DETAILED DESCRIPTION
[0051] To describe the present invention more clearly, the
present invention is further
described below with reference to the accompanying drawings.
[0052] It should be understood that, the terms such as "front",
"rear", "left", "right",
"upper", "lower", "first", and "second" are used only for ease of describing
the technical
solutions of the present invention, rather than indicating or implying that
the mentioned
apparatus or component must have a particular difference. Therefore, such
terms should not be
construed as a limitation to the present invention. It should be noted that,
when a component is
considered to be "connected to" another component, the component may be
directly connected
to the another component, or an intervening component may be present. Unless
otherwise
defined, meanings of all technical and scientific terms used in this
specification are the same as
that usually understood by a person skilled in the technical field to which
the present invention
belongs. In this specification, terms used in this specification of the
present invention are only
intended to describe objectives of the specific embodiments, but are not
intended to limit the
present invention.
[0053] FIG. 1 and FIG. 2 show an electronic vaporization device
according to some
embodiments of the present invention. The electronic vaporization device may
be provided for
a user to inhale aerosols and may include a vaporizer land a battery device 2
cooperating with
the vaporizer 1. The vaporizer 1 may be configured to store and heat and
vaporize a liquid
aerosol-generation substrate such as liquid medicine, and output aerosols. The
battery device 2
may be configured to supply power to the vaporizer 1. In some embodiments, the
vaporizer 1
and the battery device 2 may be both in a shape of a cylinder and are
mechanically and
electrically connected to each other in an axial direction. In some
embodiments, the vaporizer 1
and the battery device 2 are detachably connected to each other in a threaded
connection
manner. It may be understood that, the vaporizer 1 and the battery device 2
are not limited to
being connected through threads, and may also be detachably connected to each
other in a
magnetic attraction manner. Further, it may be understood that, the vaporizer
1 and the battery
device 2 are not limited to a shape of a cylinder, and may alternatively be in
a shape of a
column whose cross section is in a shape of an ellipse, a racetrack, or an
irregular shape.
CA 03203877 2023- 6- 29 6
[0054] As shown in FIG. 3 to FIG. 5, in some embodiments, the
vaporizer 1 may include a
cylindrical vaporization main body 10 located at a lower portion and a suction
nozzle
component 20 axially connected to an upper end of the vaporization main body
10. The
vaporization main body 10 is configured to store and heat and vaporize the
liquid
aerosol-generation substrate, and the suction nozzle component 20 is
configured to block the
liquid aerosol-generation substrate in the vaporization main body 10 and
output the aerosols. In
some embodiments, the suction nozzle component 20 is embedded in the upper end
of the
vaporization main body 10 in a tight fitting manner, which is conducive to
inject the liquid
aerosol-generation substrate into the vaporization main body 10. The suction
nozzle
component 20 may be detachably connected to the upper end of the vaporization
main body 10.
In this case, the liquid aerosol-generation substrate may be added repeatedly,
thereby
prolonging a service life of the vaporizer 1. For some disposable vaporizers
1, connection
between the suction nozzle component 20 and the vaporization main body 10 may
be
non-detachable. That is, once the suction nozzle component and the
vaporization main body
are connected, the two components are locked and cannot be separated without
destroying an
existing structure. In addition, even for a vaporizer that can be used
repeatedly, the suction
nozzle component and the vaporization main body may be integrally formed by
adding a liquid
injector, such as a vaporizer 1c shown in FIG. 16.
[0055] Referring to FIG. 6 and FIG. 7, in some embodiments, the
vaporization main body
may include a bottom base 11, a vent tube 12, a housing 13, a vaporization
assembly 14, an
electrode column 15, an insulating sealing ring 16, a first electrode claw 17,
and a second
electrode claw 18 that are assembled coaxially.
[0056] In some embodiments, the bottom base 11 may be in a shape
of a cylinder and
conductive. In some embodiments, the vent tube 12 may also be conductive, is
longitudinally
embedded in an upper portion of the bottom base 11, and is electrically
connected to the bottom
base 11. The vent tube 12 defines a columnar vaporization cavity 120. In some
embodiments,
the housing 13 may be in a shape of a cylinder, is longitudinally sleeved on
the upper portion of
the bottom base 11, and surrounds the vent tube 12. An annular liquid storage
cavity 130 is
defined between an inner wall surface of the housing 13 and an outer wall
surface of the vent
tube 12. A liquid inlet hole 122 communicating the liquid storage cavity 130
with the
vaporization cavity 120 may be further formed on the vent tube 12. In some
embodiments, the
vaporization assembly 14 may be in a shape of a cylinder and is longitudinally
arranged in the
CA 03203877 2023- 6- 29 7
vaporization cavity 120. A middle portion of the vaporization assembly 14 may
form a
longitudinally run-through airflow channel 140. The electrode column 15
longitudinally runs
through a lower portion of the bottom base 11 and is electrically insulated
from the bottom base
11. Specifically, the lower portion of the bottom base 11 is longitudinally
provided with an
insulating sealing ring 16, and the electrode column 15 further runs through
the insulating
sealing ring 16, to implement insulating and sealing connection to the bottom
base 11. One end
of the first electrode claw 17 is fixed to an inner wall of the vent tube 12
and is electrically
connected to the vent tube 12, and the other end is in elastic contact with an
upper end of the
vaporization assembly 14, so as to electrically connect the upper end of the
vaporization
assembly 14 to the vent tube 12. One end of the second electrode claw 18 is
fixed to the
electrode column 15 and is electrically connected to the electrode column 15,
and the other end
is in elastic contact with a lower end of the vaporization assembly 14, so as
to electrically
connect the lower end of the vaporization assembly 14 to the electrode column
15.
[0057] In some embodiments, the electrode column 15 is
configured to be electrically
connected to a positive electrode of the battery device 2, and the bottom base
11 is configured
to be electrically connected to a negative electrode of the battery device 2,
to form an electrical
loop. Therefore, after flowing out of the positive electrode of the battery
device 2, a current can
flow through the electrode column 15 and the second electrode claw 18
sequentially and reach
the lower end of the vaporization assembly 14; and after running through the
vaporization
assembly 14 and causing the vaporization assembly 14 to generate heat, the
current reaches the
upper end of the vaporization assembly 14, and then flows back to the negative
electrode of the
battery device 2 after flowing through the first electrode claw 17, the vent
tube 12, and the
bottom base 11 sequentially. It may be understood that, in some embodiments,
the electrode
column 15 and the bottom base 11 may alternatively be electrically connected
to the negative
electrode and the positive electrode of the battery device 2 respectively. In
this case, a flowing
direction of the current is opposite to the foregoing flowing direction.
[0058] Still referring to FIG. 6 and FIG. 7, in some
embodiments, the bottom base 11 may
be integrally formed by using a metal material and may include a circular base
111, a first
mounting tube 112 longitudinally arranged on an upper surface of the base 111,
and a second
mounting tube 113 longitudinally arranged on a bottom surface of the base 111.
A middle
portion of the base 111 is provided with a longitudinally run-through through
hole 1110, and
the through hole 1110 communicates the first mounting tube 112 with the second
mounting
CA 03203877 2023- 6- 29 8
tube 113. An outer wall surface of the second mounting tube 113 forms a
threaded structure
1131 matching threads on an upper end of the battery device 2, and a mounting
ring 1132
matching the insulating sealing ring 16 is formed on an inner wall surface.
[0059] In some embodiments, the vent tube 12 may be integrally
formed by using a metal
material and may include a first tube section 121, a second tube section 123
axially connected
to an upper end of the first tube section 121, and a third tube section 125
axially connected to a
lower end of the first tube section 121, where inner diameters and outer
diameters of the third
tube section 125, the first tube section 121, and the second tube section 123
are sequentially
decreased. The first tube section 121 defines the vaporization cavity 120, and
there may be a
plurality of liquid inlet holes 122 uniformly formed on a circumferential
direction of a side wall
of the first tube section 121. A block ring 1231 extending toward a central
axis may be arranged
at a position close to the first tube section 121 on an inner wall surface of
the second tube
section 123, which is configured to provide axial resistance force for the
first electrode claw 17.
An end surface of the block ring 1231 close to the first electrode claw 17 may
be a flat surface
perpendicular to the central axis of the second tube section 123, and an end
surface away from
the first electrode claw 17 may be a conical surface in a shape of a horn. An
outer diameter of
the third tube section 125 matches an inner diameter of the first mounting
tube 112, so that the
third tube section 125 is longitudinally embedded in the first mounting tube
112 and tightly fits
the first mounting tube 112. The height of the third tube section 125 is equal
to the height of the
first mounting tube 112. In some embodiments, to facilitate to embed the third
tube section 125
in the first mounting tube 112, a guide portion 1251 is further formed on an
outer wall surface
of the third tube section 125 close to a lower end thereof through inward
retraction, and an
outer diameter of the guide portion 125 is less than that of the first
mounting tube 112.
[0060] In some embodiments, the housing 13 may be made of a
transparent material, and
an inner diameter thereof matches the outer diameter of the first mounting
tube 112, so that the
housing 13 can be axially sleeved on the first mounting tube 112 through a
lower end and
tightly fits the first mounting tube 112. An upper end surface of the housing
13 may be slightly
lower than an upper end surface of the second tube section 123, to better
match the suction
nozzle component 20. The liquid storage cavity 130 is defined between the
inner wall surface
of the housing 13 and the inner wall surfaces of the first tube section 121
and the second tube
section 123, and an annular liquid injection opening 132 is formed between an
upper end of the
housing 13 and an upper end of the second tube section 123.
CA 03203877 2023- 6- 29 9
[0061] In some embodiments, the vaporization assembly 14 may
include a longitudinally
arranged cylindrical vaporization core 141, a first sealing ring 142 sleeved
on an upper end of
the vaporization core 141, and a second sealing ring 143 sleeved on a lower
end of the
vaporization core 141.
[0062] The first sealing ring 142 may include an L-shaped cross
section configured to seal
a gap between the upper end of the vaporization core 141 and the upper end of
the first tube
section 121. In some embodiments, the first sealing ring 142 may include a
cylindrical first
sealing portion 1421 and an annular second sealing portion 1423 connected to
an upper end
edge of the first sealing portion 1421, where the first sealing portion 1421
is sleeved on an outer
wall surface of the upper end of the vaporization core 141, and the second
sealing portion 1423
covers an upper end surface of the vaporization core 141. An inner diameter of
the second
sealing portion 1423 is preferentially greater than a pore size of the
vaporization core 141, so
that the first electrode claw 17 may not be blocked by the second sealing
portion 1423 when
matching the vaporization core 141.
[0063] The second sealing ring 143 may also include an L-shaped
cross section configured
to seal a gap between the lower end of the vaporization core 141 and the third
tube section 125.
In some embodiments, the second sealing ring 143 may include a cylindrical
third sealing
portion 1431 and an annular fourth sealing portion 1433 connected to a lower
end edge of the
third sealing portion 1431, where the third sealing portion 1431 is sleeved on
an outer wall
surface of the lower end of the vaporization core 141, and the fourth sealing
portion 1433
covers a lower end surface of the vaporization core 141. A middle portion of
the outer wall
surface of the vaporization core 141 may directly face the liquid inlet hole
122. A middle
portion of the vaporization core 141 forms a longitudinally run-through
central through hole
1410. An inner diameter of the fourth sealing portion 1433 is preferentially
greater than the
pore size of the vaporization core 141, so that the second electrode claw 18
may not be blocked
by the fourth sealing portion 1433 when matching the vaporization core 141.
[0064] In some embodiments, a first vent groove 1420 in a shape
of a labyrinth is formed
on an inner wall surface of the first sealing ring 142, and the first vent
groove 1420 runs
through inner wall surfaces of the first sealing portion 1421 and the second
sealing portion
1423. A size of the first vent groove 1420 may be designed to be small enough
to include
capillary force in a use state, so as to communicate the liquid storage cavity
130 with an airflow
channel in the vent tube 12 when the liquid storage cavity 130 is under a
relatively great
CA 03203877 2023- 6- 29 10
negative pressure, thereby achieving vapor¨liquid equilibrium and preventing
dry heating. In
some embodiments, a second vent groove 1430 in a shape of a labyrinth may also
be provided
on an inner wall surface of the second sealing ring 143, and the second vent
groove 1430 runs
through inner wall surfaces of the third sealing portion 1431 and the fourth
sealing portion
1433 and has a same function as the first vent groove 1420. In some
embodiments, the first
sealing ring 142 and the second sealing ring 143 have a same structure and may
be compatible,
thereby facilitating automated mounting and reducing mold making costs for a
sealing ring.
[0065] It may be understood that, a vent structure may be
arranged on any one of the first
sealing ring 142 or the second sealing ring 143, which have advantages and
disadvantages
respectively. When the vent structure is only arranged on the first sealing
ring 142, namely, the
first vent groove 1420 of the first sealing ring 142, if liquid leakage
occurs, some leaked liquid
may flow downward from the upper end of the vaporization core 141 and is
vaporized again
after being absorbed by the vaporization core 141. When the vent structure is
only arranged on
the second sealing ring 143, although the possible leaked liquid easily leaks
into the bottom
base 11, an airflow direction in the airflow channel is flowing upward from
the bottom, so that
air supplement through the second sealing ring 143 is smoother. In some
embodiments, the
thickness of sealing silicone, namely, a distance between a surface in contact
with the
vaporization core 141 of the second sealing ring 143 and a surface in contact
with the vent tube
12, at a lower end of the second sealing ring 143 is relatively large, so that
the second sealing
ring can better seal the lower end of the vaporization core 141 through
interference fitting,
thereby preventing liquid leakage. When comparison is performed, the thickness
of the sealing
silicon of the second sealing ring is compared with the thickness of a
corresponding part of the
first sealing ring 142.
[0066] Referring to FIG. 8, in some embodiments, the
vaporization core 141 may include a
cylindrical porous body 1411, a heating element 1412 arranged on an inner wall
surface of the
porous body 1411, a first electrode 1413 arranged at an upper end of the inner
wall surface of
the porous body 1411 and electrically connected to an upper end of the heating
element 1412,
and a second electrode 1414 arranged at a lower end of the inner wall surface
of the porous
body 1411 and electrically connected to a lower end of the heating element
1412. In some
embodiments, the porous body 1411 may be a porous ceramic and may be a small-
size porous
body 1411. In some embodiments, a length of the small-size porous body 1411
may range from
0.8 cm to 1.2 cm, and an inner diameter thereof may range from 0.18 cm to 0.22
cm.
CA 03203877 2023- 6- 29 11
[0067] In some embodiments, the heating element 1412 may be made
of a material such as
a nickel-chromium alloy, an iron-chromium-aluminum alloy, or a silver-
palladium alloy, and is
first printed or coated on an inner surface of a green body of the porous body
1411 and then
formed on the inner wall surface of the porous body 1411 in a sintering
manner. The heating
element may include two long flat and clip-shaped heating circuits B arranged
in parallel in an
axial direction of the porous body 1411 and a connection circuit C connecting
the two heating
circuits in series, where a length direction of each of the two heating
circuits B extending in a
circumferential direction of the inner wall surface of the porous body 1411,
so that the entire
heating element is C-shaped. The heating element 1412 may further include an
upper end
circuit D and a lower end circuit A connected to an upper end and a lower end
respectively,
which are electrically connected to the first electrode 1413 and the second
electrode 1414
respectively.
[0068] The first electrode 1413 and/or the second electrode 1414
may be made of a
material such as silver or copper, and specifically, may be formed on the
inner wall surface of
the cylindrical porous body 1411 by coating/printing and sintering silver
slurry or copper
slurry. In addition, the first electrode and/or the second electrode are/is at
least partially
connected to the heating element 1412. In some embodiments, the first
electrode 1413 and/or
the second electrode 1414 may be C-shaped. Generally, slurry of the heating
element 1412 is
first printed on the green body of the porous body 1411, and slurry of the
electrode is then
printed or coated, and then the slurry is sintered together. In some
embodiments, the width of a
notch of the first electrode 1413 may be less than the width of a conductive
portion 173, so that
the first electrode claw 17 is in electrical contact with all conductive
portions 173; and the
width of a notch of the second electrode 1414 may be less than the width of a
conductive
portion 183, so that the second electrode claw 18 is in electrical contact
with all conductive
portions 183. It may be understood that, in some embodiments, the heating
element 1412 may
also be made of a metal heating sheet, and the porous body 1411 is also not
limited to a porous
ceramic material and may be made of any other suitable porous body material.
It may be
understood that, the first electrode 1413 and/or the second electrode 1414
are/is not limited to
being distributed on an end portion of the inner wall surface of the porous
body 1411 in a shape
of C, and may also distributed on an entire circumferential direction of the
end portion of the
inner wall surface of the porous body 1411, namely, may be annular.
CA 03203877 2023- 6- 29 12
[0069] Arrangement of the first electrode 1413 and/or the second
electrode 1414 does not
require opening holes and introducing leads in the porous body 1411, so that
an internal
structure of the porous body 1411 is more complete, controllable, and
reliable, and the product
consistency is therefore well ensured. In addition, use of leads may be
avoided, thereby
reducing the manufacturing difficulty and production costs, which is more
apparent for the
small-size porous body 1411.
[0070] In some embodiments, by arranging the first electrode 1413
and the second
electrode 1414 at two ends of the inner wall surface of the small-size porous
body 1411
respectively may also have various benefits. An area of an inner wall of the
small-size porous
body 1411 is quite small, if two electrodes are arranged at one end, areas of
the two electrodes
are excessive small and are not conducive to establish stable electrical
connection with an
electrode connector, and a problem of short circuit may easily occur. By
arranging the first
electrode 1413 and the second electrode 1414 at two ends, deployment of the
first electrode
1413 and the second electrode 1414 may be facilitated, and areas of the first
electrode 1413 and
the second electrode 1414 may be greater, thereby facilitating to establish
stable electrical
connection with the electrode connector.
[0071] Still referring to FIG. 6 and FIG. 7, in some embodiments,
the electrode column 15
includes a central hole 150 extending upward from a lower end surface, an air
outlet hole 152
formed on a side wall of a top portion, and a clamping groove 154 formed on a
side wall
surface, where the air outlet hole 152 is in communication with the central
hole 150 for air
intaking. The clamping groove 154 is configured to be clamped with the
insulating sealing ring
16. An outer wall surface of the insulating sealing ring 16 forms a clamping
groove 160
configured to be clamped with the mounting ring 1132 of the bottom base 11.
[0072] In some embodiments, the first electrode claw 17 may be
made of a material such as
phosphor copper or 316 stainless steel, and a gold plated coating may be
arranged on a surface
of the first electrode claw. Preferably, the first electrode claw 17 is made
of a phosphor copper
material, and an impedance of the phosphor copper material is relatively
small. The first
electrode claw 17 may include a mounting portion 171 embedded in the inner
wall surface of
the second tube section 123, three extension portions 172 connected to the
mounting portion
171, and three conductive portions 173 connected to the three extension
portions 172
respectively. Each extension portion 172 and a corresponding conductive
portion 173 form an
elastic conductive arm of the first electrode claw 17. It may be understood
that, a quantity of
CA 03203877 2023- 6- 29 13
elastic conductive arms of the first electrode claw 17 is not limited to three
and may be one or
more than one, and when the first electrode claw includes a plurality of
elastic conductive arms,
electrical connection may be more reliable and assembly may be more
convenient.
[0073] In some embodiments, the mounting portion 171 may be in a
shape of a cylinder
and includes a longitudinal fracture 1710 running through two side edges,
where existence of
the fracture 1710 causes deformation during mounting, thereby ensuring that
the mounting
portion 171 is better fixed to the inner wall surface of the second tube
section 123. Specifically,
a horn-shaped guide surface 1210 is arranged at a junction of the second tube
section 123 and
the first tube section 121. In a process that the first electrode claw 17 is
axially inserted into the
second tube section 123, the guide surface 1210 applies a radially inward
component force to
the mounting portion 171 of the first electrode claw 17, so that the fracture
1710 of the
mounting portion 171 is closed, an outer diameter is reduced, and the first
electrode claw can
be inserted into the second tube section 123. After the first electrode claw
is mounted in place,
the mounting portion 171 provides a reaction force to the inner wall surface
of the second tube
section 123, so that the mounting portion can be firmly fixed to the second
tube section 123. It
may be understood that, in some embodiments, the mounting portion 171 may also
be
integrated together with the second tube section 123. In some embodiments, the
mounting
portion 171 may also be axially embedded in an upper end of the central
through hole 1410 of
the vaporization core 141 and elastically abuts against and fixed to the first
electrode 1413, so
that the elastic conductive arm extends out to be in elastic contact with the
vent tube 12.
[0074] In some embodiments, the extension portion 172 may be in
a shape of a bar and
includes good elasticity, which first bends and extends by a certain distance
from the mounting
portion 171 toward a central axis of the mounting portion 171 and then extends
in a direction
parallel to the central axis of the mounting portion 171 and away from the
mounting portion
171, to provide space for bending of the conductive portion 173 in a direction
away from the
central axis of the mounting portion 171 and provide a good elastic
characteristic. Preferably,
there are two or more than two extension portions 172, to ensure more reliable
electrical
connection; and when there are a plurality of extension portions 172, a best
situation is that the
extension portions are uniformly distributed at a lower side edge of the
mounting portion 171
and extend downward. Specifically, the extension portion 172 first obliquely
extends by a
certain distance from the mounting portion 171 toward the central axis of the
mounting portion
171, and then extends out in a direction parallel to the central axis and away
from the mounting
CA 03203877 2023- 6- 29 14
portion 171. One conductive portion 173 is arranged at a tail end of each
extension portion 172,
and is configured to be in elastic contact with the first electrode 1413 of
the vaporization core
141. In some embodiments, the conductive portion 173 may be in a shape of a
spoon.
Specifically, the conductive portion 173 first obliquely extends toward a
direction away from
the central axis of the mounting portion 171, and then bends and obliquely
extends toward a
direction of the central axis. An inclined surface of the spoon-shaped
structure leans inward
and plays a role of guiding, and a bottom portion of the spoon-shaped
structure is in arc
transition, so that the spoon-shaped structure can be in better contact with
the first electrode
1413 of the vaporization core 141 and may not scratch the first electrode 1413
during
assembly. A vertical distance between a bottom portion of the conductive
portion 173 and the
central axis is slightly greater than a radius of a position of the central
through hole 1410 of the
vaporization core 141 at the first electrode 1413. Therefore, when the
conductive portion 173 is
axially inserted into the central through hole 1410, because the conductive
portion 173 includes
an inclined surface leaning inward, a reaction force applied by the
vaporization core 141 to the
conductive portion 173 includes a component force toward the direction of the
central axis, so
that the extension portion 171 is elastically deformed toward the direction of
the central axis,
and the conductive portion 173 can be inserted in this case. After the
conductive portion 173 is
inserted into the central through hole 1410, the elasticity of the extension
portion 171 maintains
close contact between the conductive portion 173 and the first electrode 1413.
[0075] In some embodiments, the second electrode claw 18 may be
made of a material
such as phosphor copper or 316 stainless steel, and a gold plated coating may
be arranged on a
surface of the second electrode claw. Preferably, the second electrode claw 18
is made of a
phosphor copper material, and an impedance of the phosphor copper material is
relatively
small. The second electrode claw 18 may include a mounting portion 181 sleeved
on an upper
portion of the electrode column 15, an extension portion 182 connected to the
mounting portion
181, and a conductive portion 183 connected to the extension portion 182. In
some
embodiments, the mounting portion 181 may be in a shape of a cylinder and
includes a
longitudinal fracture 1810 running through two side edges, where existence of
the fracture
1810 causes deformation during mounting, thereby ensuring that the mounting
portion 181 is
better fixed to the upper portion of the electrode column 15. It may be
understood that, in some
embodiments, the mounting portion 181 may also be integrated with the
electrode column 15.
In some embodiments, the extension portion 182 may be in a shape of a bar and
includes good
elasticity. Preferably, there are two or more than two extension portions 182,
to ensure more
CA 03203877 2023- 6- 29 15
reliable electrical connection; and when there are a plurality of extension
portions 181, a best
situation is that the extension portions are uniformly distributed at a lower
side edge of the
mounting portion 181 and extend downward. One conductive portion 183 is
arranged at a tail
end of each extension portion 182, and is configured to be in elastic contact
with the second
electrode 1414 of the vaporization core 141. In some embodiments, the
conductive portion 183
may be in shape of a spoon. An inclined surface of the spoon-shaped structure
leans inward and
plays a role of guiding, and a bottom portion of the spoon-shaped structure is
in arc transition,
so that the spoon-shaped structure can be in better contact with the second
electrode 1414 of the
vaporization core 141 and may not scratch the second electrode 1414 during
assembly. In some
embodiments, the second electrode claw 18 and the first electrode claw 17 may
have a same
structure and may be compatible. In this way, the assembly difficulty and
costs may be
reduced.
[0076] During assembly of the vaporization main body 10, the
following steps may be
used:
[0077] (1) The bottom base 11, the electrode column 15, the
insulating sealing ring 16, and
the second electrode claw 18 are provided, the electrode column 15 is mounted
in the second
mounting tube 113 of the bottom base 11 through the insulating sealing ring
16, and the second
electrode claw 18 is then sleeved on a top portion of the electrode column 15,
to form a bottom
base combination body. In this case, the conductive portion 183 of the second
electrode claw
18 extends upward.
[0078] (2) The vent tube 12 and the first electrode claw 17
shown in the figure are
provided, and the first electrode claw 17 is embedded in the second tube
section 123 of the vent
tube 12, where the conductive portion 173 of the first electrode claw 17
extends downward.
[0079] (3) The vaporization core 141, the first sealing ring
142, and the second sealing ring
143 are provided, and the first sealing ring 142 and the second sealing ring
143 are respectively
sleeved on the upper and lower ends of the vaporization core 141 to form the
vaporization
assembly 14.
[0080] (4) The vaporization assembly 14 is inserted in the vent
tube 12 from bottom to top,
and the first electrode 1413 of the vaporization core 141 is in electrical
contact with the
conductive portion 173 of the first electrode claw 17, so that electrical
connection between the
CA 03203877 2023- 6- 29 16
first electrode 1413 of the vaporization core 141 and the vent tube 12 is
implemented, and a
vent tube combination body is formed.
[0081] (5) The vent tube combination body is inserted in the
first mounting tube 112 on a
top portion of the bottom base combination body, to implement tight fitting
and electrical
connection between the vent tube 12 and the bottom base 11, and the conductive
portion 183 of
the second electrode claw 18 is in contact and conducted with the second
electrode 1414 of the
vaporization core 141.
[0082] (6) The housing 13 is provided, and the housing 13 is
sleeved on the outside of the
first mounting tube 112, to implement assembly of the vaporization main body
10.
[0083] In the foregoing assembly steps of the vaporization main
body 10, the first electrode
claw 17 and the second electrode claw 18 implement quick electrical contact
and conduction
between components, which is more convenient and quick in operations when
compared with
an implementation of lead welding in the related art, so that automated
assembly of products
can be implemented more easily. It may be understood that, the serial numbers
before the steps
are only provided for ease of statement, and do not represent a sequence of
the steps. For
example, during specific assembly, the vent tube combination body may be first
constructed,
and the bottom base combination body is then constructed.
[0084] Still referring to FIG. 4 and FIG. 5, in some embodiments,
the suction nozzle
component 20 may include an annular block portion 21 and a flat suction nozzle
portion 22
connected to the annular block portion 21, where the annular block portion 21
is configured to
be embedded in the annular liquid injection opening 132 at the upper end of
the vaporization
main body 10.A middle portion of the suction nozzle portion 22 is provided
with a longitudinal
air guide hole 220, and the air guide hole 220 is configured to be in
communication with the
upper end of the second tube section 123 of the vent tube 12, to output a
mixture of aerosols and
air.
[0085] During assembly of the vaporizer 1, the liquid aerosol-
generation substrate is first
injected in the liquid storage cavity 130 of the vaporization main body 10
through the liquid
injection opening 132, the suction nozzle component 20 is then inserted in the
liquid injection
opening 132 to seal the liquid storage cavity 130 after the liquid storage
cavity is filled, and the
air guide hole 220 of the suction nozzle component 20 is in communication with
the vent tube
12. In this case, the liquid aerosol-generation substrate reaches a periphery
of the vaporization
CA 03203877 2023- 6- 29 17
core 141 through the liquid inlet hole 122, and the porous body 1411 of the
vaporization core
141 absorbs the liquid aerosol-generation substrate through capillary force to
the inner surface
so as to be in contact with the heating element 1412. During use, the
vaporization assembly 1 is
mounted onto the battery device 2. When a user inhales through the suction
nozzle portion 22,
as shown by arrows X in FIG. 3, external air enters through the central hole
150 of the electrode
column 15, enters the central through hole 1410 of the vaporization core 141
after flowing
through the through hole 1110 of the bottom base 11, and is then outputted
through the air
guide hole 220 of the suction nozzle component 20. Meanwhile, an air switch
(not shown in the
figure) in the battery device 2 is conducted, to drive the battery device 2 to
supply power to the
vaporizer 1. The heating element 1412 of the vaporization core 141 generates
heat after being
energized, to heat and vaporize the liquid aerosol-generation substrate on the
inner surface of
the porous body 1411 to form aerosols, and the aerosols are carried out by an
airflow after the
aerosols are mixed in the air flowing through the central through hole 1410.
[0086] FIG. 9 to FIG. 11 show a vaporization main body 10a in
some embodiments of the
present invention, a housing is omitted in the figures, and the vaporization
main body 10a may
be used as an alternative of the vaporization main body 10. As shown in the
figure, in some
embodiments, the vaporization main body 10a may include a bottom base 11a, a
vent tube 12a,
a vaporization assembly 14a, an electrode column 15a, an insulating sealing
ring 16a, a first
electrode claw 17a, and a second electrode claw 18a that are assembled
coaxially. In some
embodiments, the bottom base 11a may be in a shape of a cylinder and
conductive. In some
embodiments, the vent tube 12a may also be conductive, is longitudinally
embedded in an
upper portion of the bottom base 11a, and is electrically connected to the
bottom base 11a. The
vent tube 12a defines a columnar vaporization cavity 120a. A liquid inlet hole
122a
communicating a liquid storage cavity with the vaporization cavity 120a may be
further formed
on the vent tube 12a. In some embodiments, the vaporization assembly 14a may
be in a shape
of a cylinder and is longitudinally arranged in the vaporization cavity 120a.
A middle portion
of the vaporization assembly 14a may form a longitudinally run-through airflow
channel 140a.
The electrode column 15a longitudinally runs through a lower portion of the
bottom base 11a
and is electrically insulated from the bottom base 11a. Specifically, the
lower portion of the
bottom base 11a is longitudinally provided with an insulating sealing ring
16a, and the
electrode column 15a further runs through the insulating sealing ring 16a, to
implement
insulating and sealing connection to the bottom base 11a. One end of the first
electrode claw
17a is fixed to an inner wall of the vent tube 12a and is electrically
connected to the vent tube
CA 03203877 2023- 6- 29 18
12a, and the other end is in elastic contact with an upper end of the
vaporization assembly 14a,
so as to electrically connect the upper end of the vaporization assembly 14a
to the vent tube
12a. One end of the second electrode claw 18a is fixed to the electrode column
15a and is
electrically connected to the electrode column 15a, and the other end is in
elastic contact with a
lower end of the vaporization assembly 14a, so as to electrically connect the
lower end of the
vaporization assembly 14a to the electrode column 15a.
[0087] In some embodiments, the electrode column 15a is
configured to be electrically
connected to a positive electrode of a battery device 2a, and the bottom base
ha is configured
to be electrically connected to a negative electrode of the battery device 2a,
to form an
electrical loop. Therefore, after flowing out of the positive electrode of the
battery device 2a, a
current can flow through the electrode column 15a and the second electrode
claw 18a
sequentially and reach the lower end of the vaporization assembly 14a; and
after running
through the vaporization assembly 14a and causing the vaporization assembly
14a to generate
heat, the current reaches the upper end of the vaporization assembly 14a, and
then flows back
to the negative electrode of the battery device 2a after flowing through the
first electrode claw
17a, the vent tube 12a, and the bottom base 11a sequentially. It may be
understood that, in
some embodiments, the electrode column 15a and the bottom base 11a may
alternatively be
electrically connected to the negative electrode and the positive electrode of
the battery device
2a respectively. In this case, a flowing direction of the current is opposite
to the foregoing
flowing direction.
[0088] In some embodiments, the bottom base 11a may be
integrally formed by using a
metal material and may include a circular base 111a and a second mounting tube
113a
longitudinally arranged on a bottom surface of the base 111a. A middle portion
of the base
111a is provided with a longitudinally run-through through hole 1110a, and the
through hole
1110a communicates a first tube section 121a of the vent tube 12a with the
second mounting
tube 113a. A mounting ring 1132a matching the insulating sealing ring 16a is
formed on an
inner wall surface of the second mounting tube 113a. An air inlet hole 1130a
is further formed
on a side wall of the second mounting tube 113a.
[0089] In some embodiments, the vent tube 12a may include a
first tube section 121a
integrally formed with the bottom base 11a and a second tube section 123a
axially embedded in
an upper end of the first tube section 121a and electrically connected to the
first tube section
121a. The first tube section 121a defines the vaporization cavity 120a, and
there may be a
CA 03203877 2023- 6- 29 19
plurality of liquid inlet holes 122a uniformly formed on a circumferential
direction of a side
wall of the first tube section 121a. A block ring 1231a may be arranged at a
position close to the
first tube section 121a on an inner wall surface of the second tube section
123a, which is
configured to provide axial resistance force for the first electrode claw 17a.
[0090] In some embodiments, the vaporization assembly 14a may
include a longitudinally
arranged cylindrical vaporization core 141a, a first sealing ring 142a sleeved
on an upper end
of the vaporization core 141a, and a second sealing ring 143a sleeved on a
lower end of the
vaporization core 141a. The first sealing ring 142a may include an L-shaped
cross section
configured to seal gaps between the upper end of the vaporization core 141a
with the first tube
section 121a and the second tube section 123a. The second sealing ring 143a
may also include
an L-shaped cross section configured to seal a gap between the lower end of
the vaporization
core 141a and the bottom base 11a. A middle portion of the outer wall surface
of the
vaporization core 141a may directly face the liquid inlet hole 122a. In some
embodiments, the
first sealing ring 142a and the second sealing ring 143a may have a same
structure.
[0091] In some embodiments, a first vent groove 1420a in a shape
of a labyrinth is formed
on an inner wall surface of the first sealing ring 142a. A size of the first
vent groove 1420a may
be designed to be small enough to include capillary force in a use state, so
as to communicate
the liquid storage cavity with an airflow channel in the vent tube 12a when
the liquid storage
cavity is under a relatively great negative pressure, thereby achieving
vapor¨liquid equilibrium
and preventing dry heating. In some embodiments, a second vent groove 1430a in
a shape of a
labyrinth may also be provided on an inner wall surface of the second sealing
ring 143a, which
has a same function as the first vent groove 1420a. It may be understood that,
a vent groove
may be arranged on any one of the first sealing ring 142a or the second
sealing ring 143a. In
some embodiments, the first sealing ring 142a and the second sealing ring 143a
may have a
same structure and may be compatible.
[0092] Still referring to FIG. 11, in some embodiments, the
vaporization core 141a may
include a cylindrical porous body 1411a, a heating element 1412a arranged on
an inner wall
surface of the porous body 1411a, a first electrode 1413a arranged at an upper
end of the inner
wall surface of the porous body 1411a and electrically connected to an upper
end of the heating
element 1412a, and a second electrode 1414a arranged at a lower end of the
inner wall surface
of the porous body 1411a and electrically connected to a lower end of the
heating element
CA 03203877 2023- 6- 29 20
1412a. In some embodiments, a structure of the vaporization core 141a may be
the same as a
structure of the vaporization core 141, which may be compatible.
[0093] In some embodiments, the electrode column 15a includes a
central hole 150a
extending downward from an upper end surface. In some embodiments, the
electrode column
15a may include a bottom wall 155a to block the central hole 150a, so that the
central hole 150a
can accommodate leaked liquid and prevent the leaked liquid from leaking to
the outside. In
some embodiments, an upper end of an inner wall surface of the central hole
150a is further
provided with a block ring 156a to block the second electrode claw 18a. An
outer wall surface
of the insulating sealing ring 16a forms a clamping groove 160a configured to
be clamped with
the mounting ring 1132a of the bottom base ha.
[0094] In some embodiments, the first electrode claw 17a may be
made of an elastic metal
material, and may include a mounting portion 171a embedded in the inner wall
surface of the
second tube section 123a, an extension portion 172a connected to the mounting
portion 171a,
and a conductive portion 173a connected to the extension portion 172a. In some
embodiments,
the mounting portion 171a may be in a shape of a cylinder and include a
longitudinal fracture
1710a running through upper and lower side edges, where existence of the
fracture 1710a
causes the mounting portion 171a to match an error of an inner diameter size
of the second tube
section 123a, thereby improving the applicability. In some embodiments, the
extension portion
172a may be in a shape of a bar, and preferably, there may be three or more
than three
extension portions. The three or more than three extension portions 171a are
uniformly
connected to a lower side edge of the mounting portion 171a and extend
downward. One
conductive portion 173a is arranged at a tail end of each extension portion
172a, and is
configured to be in elastic contact with the first electrode 1413a of the
vaporization core 141a,
so as to implement conduction and improve the assembly efficiency. In some
embodiments, the
first electrode claw 17a and the first connector 17 may have a same structure,
which may be
compatible.
[0095] In some embodiments, the second electrode claw 18a may
have a same structure as
the first electrode claw 17a, which may also be made of an elastic metal
material and include a
mounting portion 181a embedded in the central hole 150a of the electrode
column 15a, an
extension portion 182a connected to the mounting portion 181a, and a
conductive portion 183a
connected to the extension portion 182a. In some embodiments, the mounting
portion 181a
may be in a shape of a cylinder and include a longitudinal fracture 1810a
running through
CA 03203877 2023- 6- 29 21
upper and lower side edges, where existence of the fracture 1810a causes the
mounting portion
181a to match an error of a size of the central hole 150a of the electrode
column 15a, thereby
improving the applicability. In some embodiments, the extension portion 182a
may be in a
shape of a bar, and preferably, there may be three or more than three
extension portions. The
three or more than three extension portions 181a are uniformly connected to a
lower side edge
of the mounting portion 181a and extend downward. One conductive portion 183a
is arranged
at a tail end of each extension portion 182a, and is configured to be in
elastic contact with the
second electrode 1414a of the vaporization core 141a, so as to implement
conduction and
improve the assembly efficiency. In some embodiments, the second electrode
claw 18a and the
second connector 18 may have a same structure, which may be compatible.
[0096] During assembly of the vaporization main body 10a, the
following steps may be

[0103] FIG. 12 to FIG. 14 show a vaporization main body 10b in
some embodiments of the
present invention, where the vaporization main body 10b may be used as an
alternative of the
vaporization main body 10, and has same appearance as the vaporization main
body 10. As
shown in the figure, in some embodiments, the vaporization main body 10b may
include a
bottom base 11b, a vent tube 12b, a housing 13b, a vaporization assembly 14b,
an electrode
column 15b, an insulating sealing ring 16b, a first electrode claw 17b, and a
second electrode
claw 18b that are assembled coaxially.
[0104] In some embodiments, the bottom base llb may be in a shape
of a cylinder and
conductive. In some embodiments, the vent tube 12b may also be conductive, is
longitudinally
embedded in an upper portion of the bottom base 11b, and is electrically
connected to the
bottom base 11b. The vent tube 12b defines a columnar vaporization cavity
120b. In some
embodiments, the housing 13b may be in a shape of a cylinder, is
longitudinally sleeved on the
upper portion of the bottom base 11b, and surrounds the vent tube 12b. An
annular liquid
storage cavity 130b is defined between an inner wall surface of the housing
13b and an outer
wall surface of the vent tube 12b. A liquid inlet hole 122b communicating the
liquid storage
cavity 130b with the vaporization cavity 120b may be further formed on the
vent tube 12b. In
some embodiments, the vaporization assembly 14b may be in a shape of a
cylinder and is
longitudinally arranged in the vaporization cavity 120b. A middle portion of
the vaporization
assembly 14b may form a longitudinally run-through central through hole 1410b.
The
CA 03203877 2023- 6- 29 23
electrode column 15b longitudinally runs through a lower portion of the bottom
base 11b and is
electrically insulated from the bottom base 11b. Specifically, the lower
portion of the bottom
base 11b is longitudinally provided with an insulating sealing ring 16b, and
the electrode
column 15b further runs through the insulating sealing ring 16b, to implement
insulating and
sealing connection to the bottom base 11b. One end of the first electrode claw
17b is fixed to an
upper end of the vaporization assembly 14a and is electrically connected to
the upper end of the
vaporization assembly 14b, and the other end is in elastic contact with an
inner wall of the vent
tube 12b, so as to electrically connect the upper end of the vaporization
assembly 14b to the
vent tube 12b. One end of the second electrode claw 18b is fixed to a lower
end of the
vaporization assembly 14b and is electrically connected to the lower end of
the vaporization
assembly 14b, and the other end is in elastic contact with the electrode
column 15b, so as to
electrically connect the lower end of the vaporization assembly 14b to the
electrode column
15b.
[0105] In some embodiments, the electrode column 15b is
configured to be electrically
connected to a positive electrode of a battery device 2b, and the bottom base
lib is configured
to be electrically connected to a negative electrode of the battery device 2b,
to form an
electrical loop. Therefore, after flowing out of the positive electrode of the
battery device 2b, a
current can flow through the electrode column 15b and the second electrode
claw 18b
sequentially and reach the lower end of the vaporization assembly 14b; and
after running
through the vaporization assembly 14b and causing the vaporization assembly
14b to generate
heat, the current reaches the upper end of the vaporization assembly 14b, and
then flows back
to the negative electrode of the battery device 2b after flowing through the
first electrode claw
17b, the vent tube 12b, and the bottom base 11b sequentially. It may be
understood that, in
some embodiments, the electrode column 15b and the bottom base 11b may
alternatively be
electrically connected to the negative electrode and the positive electrode of
the battery device
2b respectively. In this case, a flowing direction of the current is opposite
to the foregoing
flowing direction.
[0106] Still referring to FIG. 13 and FIG. 14, in some
embodiments, the bottom base 11b
may be integrally formed by using a metal material and may include a circular
base 111b, a first
mounting tube 112b longitudinally arranged on an upper surface of the base
111b, and a second
mounting tube 113b longitudinally arranged on a bottom surface of the base
111b. A middle
portion of the base 111b is provided with a longitudinally run-through through
hole 1110b, and
CA 03203877 2023- 6- 29 24
the through hole 1110b communicates the first mounting tube 112b with the
second mounting
tube 113b. An outer wall surface of the second mounting tube 113b forms a
threaded structure
1131b matching threads on an upper end of the battery device 2b, and a
mounting ring 1132b
matching the insulating sealing ring 16b is formed on an inner wall surface.
In some
embodiments, the bottom base lib and the bottom base 11 may have a same
structure and may
be compatible.
[0107] In some embodiments, the vent tube 12b may be integrally
formed by using a metal
material and may include a first tube section 121b, a second tube section 123b
axially
connected to an upper end of the first tube section 121b, and a third tube
section 125b axially
connected to a lower end of the first tube section 121b, where inner diameters
and outer
diameters of the third tube section 125b, the first tube section 121b, and the
second tube section
123b are sequentially decreased. The first tube section 121b defines the
vaporization cavity
120b, and there may be a plurality of liquid inlet holes 122b uniformly formed
on a
circumferential direction of a side wall of the first tube section 121b. An
outer diameter of the
third tube section 125b matches an inner diameter of the first mounting tube
112b, so that the
third tube section 125b is longitudinally embedded in the first mounting tube
112b and tightly
fits the first mounting tube 112b. The height of the third tube section 125b
is equal to the height
of the first mounting tube 112b. In some embodiments, to facilitate to embed
the third tube
section 125b in the first mounting tube 112b, a guide portion 1251b is further
formed on an
outer wall surface of the third tube section 125b close to a lower end thereof
through inward
retraction, and an outer diameter of the guide portion 125b is less than that
of the first mounting
tube 112b. In some embodiments, a horn-shaped guide surface 1210b leaning
outward may be
arranged on an inner wall surface of a junction of the first tube section 121b
and the second
tube section 123b, which is configured to match the conductive portion 173b of
the first
electrode claw 17b, thereby facilitating smooth connection between the
conductive portion
173b and the vent tube 12b, and facilitating quick assembly.
[0108] In some embodiments, the housing 13b may be made of a
transparent material, and
an inner diameter thereof matches the outer diameter of the first mounting
tube 112b, so that
the housing 13b can be axially sleeved on the first mounting tube 112b through
a lower end and
tightly fits the first mounting tube 112b. An upper end surface of the housing
13b may be
slightly lower than an upper end surface of the second tube section 123b, to
better match the
suction nozzle component 20. The liquid storage cavity 130b is defined between
the inner wall
CA 03203877 2023- 6- 29 25
surface of the housing 13b and the inner wall surfaces of the first tube
section 121b and the
second tube section 123b, and an annular liquid injection opening 132b is
formed between an
upper end of the housing 13b and an upper end of the second tube section 123b.
[0109] In some embodiments, the vaporization assembly 14b may
include a longitudinally
arranged cylindrical vaporization core 141b, a first sealing ring 142b sleeved
on an upper end
of the vaporization core 141b, and a second sealing ring 143b sleeved on a
lower end of the
vaporization core 141b. The first sealing ring 142b may include an L-shaped
cross section
configured to seal a gap between the upper end of the vaporization core 141b
and the upper end
of the first tube section 121b. The second sealing ring 143b may also include
an L-shaped cross
section configured to seal a gap between the lower end of the vaporization
core 141b and the
third tube section 125b. A middle portion of the outer wall surface of the
vaporization core
141b may directly face the liquid inlet hole 122b. A middle portion of the
vaporization core
141b forms a longitudinally run-through central through hole 1410b.
[0110] Referring to FIG. 15, in some embodiments, the
vaporization core 141b may
include a cylindrical porous body 1411b, a heating element 1412b arranged on
an inner wall
surface of the porous body 1411b, a first electrode 1413b arranged at an upper
end of the
porous body 1411b and electrically connected to an upper end of the heating
element 1412b,
and a second electrode 1414b arranged at a lower end of the porous body 1411b
and electrically
connected to a lower end of the heating element 1412b. In some embodiments,
the heating
element 1412b may be formed on an inner wall surface of the porous body 1411b
in a manner
of silk-screening, printing, or coating heating film slurry on an inner
surface of a green body of
the porous body 1411b and then sintering the slurry to form a heating circuit.
In some
embodiments, the heating element may be spirally distributed on the inner wall
surface of the
porous body 1411b along a longitudinal direction of the porous body 1411b.
[0111] In some embodiments, the first electrode 1413b and/or the
second electrode 1414b
may be formed on a surface of the cylindrical porous body 1411b by coating and
sintering
silver slurry, and at least partially connected to the heating element 1412b.
In some
embodiments, the first electrode 1413b includes a cylindrical first electrode
portion M and a
circular ring-shaped second electrode portion N connected to an upper end edge
of the first
electrode portion M. The first electrode portion M is formed at an upper end
of the inner wall
surface of the porous body 1411b and is connected to the upper end of the
heating element
1412b. The second electrode portion N is formed on an upper end surface of the
heating
CA 03203877 2023- 6- 29 26
element 1412b and is connected to the first electrode claw 17b. In some
embodiments, the
second electrode 1414b includes a cylindrical third electrode portion P and a
circular
ring-shaped fourth electrode portion Q connected to a lower end edge of the
third electrode
portion P. The third electrode portion P is formed at a lower end of the inner
wall surface of the
porous body 1411b and is connected to the lower end of the heating element
1412b. The fourth
electrode portion Q is formed on a lower end surface of the heating element
1412b and is
connected to the second electrode claw 18b. In some embodiments, the first
electrode 1413b
may not be provided with the first electrode portion M, and the second
electrode 1414b may
not be provided with the third electrode portion P. That is, the first
electrode 1413b and the
second electrode 1414b are only arranged on an end surface of the porous body
1411b. In this
way, a structure of an electrode becomes very simple, and a printing or
coating forming process
becomes simpler, thereby providing great convenience for the diversity of
electrical
connection. For example, a vaporization main body 1d shown in FIG. 21
implements electrical
connection through conductive silicone.
[0112] Still referring to FIG. 13 and FIG. 14, in some
embodiments, the electrode column
15b includes a central hole 150b extending upward from a lower end surface, an
air outlet hole
152b formed on a side wall of a middle portion, and a clamping groove 154b
formed on a side
wall surface, where the air outlet hole 152b is in communication with the
central hole 150b for
air intaking. The clamping groove 154b is configured to be clamped with the
insulating sealing
ring 16b. An outer wall surface of the insulating sealing ring 16b forms a
clamping groove
160b configured to be clamped with the mounting ring 1132b of the bottom base
11b.
Preferably, an upper end of the electrode column 15b runs through the through
hole 1110b of
the bottom base 11b, and extends to a position near the lower end of the
vaporization core
141b, so as to be in contact and conducted with the second electrode claw 18b
arranged at the
lower end of the vaporization core 141b.
[0113] In some embodiments, the first electrode claw 17b may be
made of a material such
as phosphor copper or 316 stainless steel, and a gold plated coating may be
arranged on a
surface of the first electrode claw. Preferably, the first electrode claw 17b
is made of a
phosphor copper material, and an impedance of the phosphor copper material is
relatively
small. The first electrode claw 17b may include a mounting portion 171b
sandwiched between
an upper end surface of the vaporization core 141b and the first sealing ring
142b, an extension
portion 172b connected to the mounting portion 171b, and a conductive portion
173b
CA 03203877 2023- 6- 29 27
connected to the extension portion 172b. Each extension portion 172b and a
corresponding
conductive portion 173b form an elastic conductive arm of the first electrode
claw 17b. It may
be understood that, a quantity of elastic conductive arms of the first
electrode claw 17b is not
limited to three and may be one or more than one, and when the first electrode
claw includes a
plurality of elastic conductive arms, electrical connection may be more
reliable and assembly
may be more convenient.
[0114] In some embodiments, the mounting portion 171b may be in
a shape of a circular
ring-shaped sheet, and is in electrical contact with the second electrode
portion N of the first
electrode 1413b. In some embodiments, the extension portion 172b may be in a
shape of a bar
and includes good elasticity. Preferably, there are two or more than two
extension portions
172b, to ensure more reliable electrical connection; and when there are a
plurality of extension
portions 172b, a best situation is that the extension portions are uniformly
distributed at an
inner ring of the mounting portion 171b and extend upward. One conductive
portion 173b is
arranged at a tail end of each extension portion 172b, and is configured to be
in elastic contact
with the vent tube 12b. In some embodiments, the conductive portion 173b may
be in shape of
a spoon. An inclined surface of the spoon-shaped structure leans inward and
plays a role of
guiding, and a bottom portion of the spoon-shaped structure is in arc
transition, so that the
spoon-shaped structure can be in better contact and conducted with the vent
tube 12b. In some
embodiments, the mounting portion 171b further includes several first convex
points 174b
protruding toward the upper end surface of the vaporization core 141b. Burrs
may be easily
generated in a manufacturing process of the mounting portion 171b in a shape
of a circular
ring-shape sheet, and as a result, contact between the mounting portion 171b
and the upper end
surface of the vaporization core 141b may be not stable enough. By adding the
first convex
points 174b, the mounting portion can be in better contact with the first
electrode 1413b on the
upper end surface of the vaporization core 141b, and the consistency is
better. Preferably, a
quantity of the first convex points 174b ranges from two to three, and the
first convex points are
uniformly distributed in a circumferential direction of the mounting portion
171b.
[0115] In some embodiments, the second electrode claw 18b may be
made of a material
such as phosphor copper or 316 stainless steel, and a gold plated coating may
be arranged on a
surface of the second electrode claw. Preferably, the second electrode claw
18b is made of a
phosphor copper material, and an impedance of the phosphor copper material is
relatively
small. The second electrode claw 18b may include a mounting portion 181b
sandwiched
CA 03203877 2023- 6- 29 28
between a lower end surface of the vaporization core 141b and the second
sealing ring 143b, an
extension portion 182b connected to the mounting portion 181b, and a
conductive portion 183b
connected to the extension portion 182b. Each extension portion 182b and a
corresponding
conductive portion 183b form an elastic conductive arm of the second electrode
claw 18b. It
may be understood that, a quantity of elastic conductive arms of the second
electrode claw 18b
is not limited to three and may be one or more than one, and when the second
electrode claw
includes a plurality of elastic conductive arms, electrical connection may be
more reliable and
assembly may be more convenient.
[0116] In some embodiments, the mounting portion 181b may be in
a shape of a circular
ring-shaped sheet, and is in electrical contact with the fourth electrode
portion Q of the second
electrode 1414b. In some embodiments, the extension portion 182b may be in a
shape of a bar
and includes good elasticity. Preferably, there are two or more than two
extension portions
182b, to ensure more reliable electrical connection; and when there are a
plurality of extension
portions 182b, a best situation is that the extension portions are uniformly
distributed at an
inner ring of the mounting portion 181b and extend downward. One conductive
portion 183b is
arranged at a tail end of each extension portion 182b, and is configured to be
in elastic contact
with the upper end of the electrode column 15b. In some embodiments, the
conductive portion
183b may be in shape of a spoon. An inclined surface of the spoon-shaped
structure leans
outward and plays a role of guiding, and a bottom portion of the spoon-shaped
structure is in
arc transition, so that the spoon-shaped structure can be in better contact
and conducted with a
side wall surface of the upper end of the electrode column 15b. In some
embodiments, the
mounting portion 181b further includes several second convex points 184b
protruding toward
the lower end surface of the vaporization core 141b. Burrs may be easily
generated in a
manufacturing process of the mounting portion 181b in a shape of a circular
ring-shape sheet,
and as a result, contact between the mounting portion 181b and the lower end
surface of the
vaporization core 141b may be not stable enough. By adding the second convex
points 184b,
the mounting portion can be in better contact with the second electrode 1414b
on the lower end
surface of the vaporization core 141b, and the consistency is better.
Preferably, a quantity of
the second convex points 184b ranges from two to three, and the second convex
points are
uniformly distributed in a circumferential direction of the mounting portion
181b.
[0117] During assembly of the vaporization main body 10b, the
following steps may be
used:
CA 03203877 2023- 6- 29 29
[0118] (1) The bottom base 11b, the electrode column 15b, and the
insulating sealing ring
16b are provided, and the electrode column 15b is mounted into the second
mounting tube
113b of the bottom base 11b through the insulating sealing ring 16b to form a

combination body.
[0119] (2) The vaporization core 141b, the first sealing ring
142b, the second sealing ring
143b, the first electrode claw 17b, and the second electrode claw 18b are
provided; the first
electrode claw 17b is arranged on the upper end surface of the vaporization
core 141b, and the
first sealing ring 142b is then sleeved on the upper end of the vaporization
core 141b, so that
the mounting portion 171b of the first electrode claw 17b is sandwiched
between the upper end
surface of the vaporization core 141b and the first sealing ring 142b, and the
conductive portion
173b of the first electrode claw 17b extends upward from the inner ring of the
first sealing ring
142b; and the second electrode claw 18b is arranged on the lower end surface
of the
vaporization core 141b, and the second sealing ring 143b is then sleeved on
the lower end of
the vaporization core 141b, so that the mounting portion 181b of the second

the second
sealing ring 143b, and the conductive portion 183b of the second electrode
claw 18b extends
downward from the inner ring of the second sealing ring 143b. Therefore, a
vaporization core
combination body is formed.

core combination body is
inserted in the first tube section 121b and the third tube section 125b of the
vent tube 12b,
where the conductive portion 173b of the first electrode claw 17b is in
contact and conducted
with a junction of the first tube section 121b and the second tube section
123b, to implement
electrical connection between the upper end of the vaporization core 141b and
the vent tube
12b. Therefore, a vent tube combination body is formed.
[0121] (4) The vent tube combination body is inserted in the
first mounting tube 112b on a
top portion of the bottom base combination body, to implement tight fitting
and electrical
connection between the vent tube 12b and the bottom base 11b, and the
conductive portion
183b of the second electrode claw 18b is in contact and conducted with the
side wall surface of
the upper end of the electrode column 15b.
[0122] (5) The housing 13b is provided, and the housing 13b is
sleeved on the outside of
the first mounting tube 112b, to implement assembly of the vaporization main
body 10b.
CA 03203877 2023- 6- 29 30
[0123] In the foregoing assembly steps of the vaporization main
body 10b, the first
electrode claw 17b and the second electrode claw 18b implement quick
electrical contact and
conduction between components, which is more convenient and quick in
operations when
compared with an implementation of lead welding in the related art, so that
automated
assembly of products can be implemented more easily.
[0124] FIG. 16 to FIG. 19 show a vaporizer lc in some
embodiments of the present
invention. The vaporizer lc may include a bottom base 11c, a vent tube 12c, a

the vent tube 12c.
A liquid inlet hole 122c communicating the liquid storage cavity 130c with the
vaporization

longitudinally arranged in the
vaporization cavity 120c, and a middle portion of the vaporization assembly
14c may form a
longitudinally run-through airflow channel 140c. The first electrode column
15c and the
second electrode column 16c run through the bottom base 11c respectively and
are electrically
connected to the vaporization assembly 14c respectively, to electrically
connect a positive
electrode and a negative electrode of a battery device to the vaporization
assembly 14c
respectively. The liquid injection device 17c runs through the bottom base
11c, communicates
the liquid storage cavity 130 with the outside, and is configured to inject a
liquid
aerosol-generation substrate into the liquid storage cavity 130. Preferably,
the bottom shell 18c

base 11c, and
clamped with the housing 13c. The bottom shell 18c can be further adsorbed to
a magnet on the
battery device, to implement detachable connection between the vaporizer lc
and the battery

[0125] In some embodiments, the bottom base 11c may be in a
shape of a racetrack and
may include a hard lower base body 111c and a soft upper base body 112c

embedding the
vent tube 12c, and an air inlet hole 1112c running through to a bottom surface
of the lower base
body 111c is formed at a middle portion of a bottom wall of the accommodating
cavity 1110c.
A first mounting hole 1113c and a second mounting hole 1114c running through
to the bottom
surface of the lower base body 111c may be further included on the bottom wall
of the
accommodating cavity 1110c, which are provided for embedding lower ends of the
first
electrode column 15c and the second electrode column 16c respectively. The

a first sealing portion
1121c surrounding the vent tube 12c, a second sealing portion 1122c
surrounding a periphery
of the lower base body 111c, and a third sealing portion 1123c surrounding the
liquid injection
device 17c. The first sealing portion 1121c is configured to prevent the
liquid substrate from
leaking from a joint between the bottom base 11c and the vent tube 12c, the
second sealing
portion 1122c is configured to prevent the liquid substrate from leaking from
a joint between
the bottom base 11c and the inner wall surface of the housing 13c, and the
third sealing portion
1123c is configured to prevent the liquid substrate from leaking from a joint
between the
bottom base 11c and an outer wall surface of the liquid injection device 17c.
[0128] In some embodiments, the vent tube 12c may include a
first tube section 121c
longitudinally inserted in a top portion of the bottom base 11c, a second tube
section 123c
axially connected to an upper end of the first tube section 121c, and a third
tube section 125c

embodiments, both
the first tube section 121c and the second tube section 123c may be in a shape
of a cylinder, and
the first tube section and the second tube section may have the same diameter
and may be
integrally formed; and a block ring 124c may be arranged between inner wall
surfaces of the
first tube section 121c and the second tube section 123c. The third tube
section 125c may be
integrally connected in the housing 13c, a lower end of the third tube section
is inserted in the
upper end of the second tube section 123c, and the third tube section and the
second tube
section are sealed by using a sealing ring 126c. The first tube section 121c
defines the
CA 03203877 2023- 6- 29 32
vaporization cavity 120c, and there may be a plurality of liquid inlet holes
122c uniformly
formed on a circumferential direction of a side wall of the first tube section
121c. A block ring
1231c extending toward a central axis may be arranged at a position close to
the first tube
section 121c on the inner wall surface of the second tube section 123c, which
is configured to
provide axial resistance force for the vaporization assembly 14c.
[0129] In some embodiments, the housing 13c may be made of a
transparent material, and
appearance thereof is approximately in a shape of a parabola. A lower end of
the housing 13c
includes a racetrack-shaped opening, and the opening is sleeved on the bottom
base 11c. An
upper end of the housing 13c includes a flat suction nozzle portion, an
opening 132c is
provided on the suction nozzle portion, and the opening 132c is in
communication with the
third tube section 125c of the vent tube 12c.
[0130] In some embodiments, the vaporization assembly 14c may
include a longitudinally
arranged cylindrical vaporization core 141c, a first sealing ring 142c
arranged on an upper end
of the vaporization core 141c, and a second sealing ring 143c arranged on a
lower end of the
vaporization core 141c. The first sealing ring 142c is configured to seal a
gap between the
upper end of the vaporization core 141c and the upper end of the first tube
section 121c. The
second sealing ring 143c is configured to seal a gap between the lower end of
the vaporization
core 141c and a lower end of the first tube section 121c. A middle portion of
an outer wall
surface of the vaporization core 141c may directly face the liquid inlet hole
122c. A middle
portion of the vaporization core 141c forms a longitudinally run-through
central through hole
1410c.
[0131] Referring to FIG. 20, in some embodiments, the
vaporization core 141c may
include a cylindrical porous body 1411c, a first heating element 1412c and a
second heating
element 1415c arranged on an inner wall surface of the porous body 1411c, an
electrical
connection portion 1416c arranged on an upper end surface of the porous body

cylinder, and may be in a
shape of another cylinder such as a square cylinder or an elliptical cylinder.
CA 03203877 2023- 6- 29 33
[0132] In some embodiments, the porous body 1411c may be made of
a porous ceramic. In
some embodiments, the first heating element 1412c and the second heating
element 1415c may
be a heating circuit and may be formed on the inner wall surface of the porous
body 1411b in a
manner of printing or coating heating film slurry (for example, silver slurry
or copper slurry)
on an inner surface of a green body of the porous body 1411c and then
sintering the slurry. In
some embodiments, the first electrode 1413c, the second electrode 1414c, and
the electrical
connection portion 1416c may be formed in a manner of printing or coating
conductive film
slurry such as silver slurry on a green body of a porous body and then
sintering the slurry. It
may be understood that, in some embodiments, the first heating element 1412c,
the second
heating element 1415c, the first electrode 1413c, the second electrode 1414c,
and the electrical
connection portion 1416c may also be formed by processing a heating metal
sheet. In some
embodiments, the first electrode 1413c and the second electrode 1414c may be
in a shape of a
fan, and there is a gap between the first electrode and the second electrode.
A groove 1417c is
provided on the lower end surface of the porous body 1411c corresponding to
the gap between
the first electrode 1413c and the second electrode 1414c, and in some
embodiments, the
electrical connection portion 1416c may be in a shape of a circular ring. In
some embodiments,
a lower end portion of the porous body 1411c includes a relatively great
diameter, which on
one hand may be in better contact with the first electrode column 15c and the
second electrode
column 16c, and is also provided to open the groove 1417c more easily to
segment the first
electrode 1413c and the second electrode 1414c. In some embodiments, the first
electrode
column 15c and the second electrode column 16c may be an elastic ejector pin.
[0133] In some embodiments, the first heating element 1412c may
include several first
heating bars distributed in a longitudinal direction of the inner wall surface
of the porous body
1411c at intervals and in parallel, and the first heating bars form first
heating circuits
distributed at intervals and in parallel, where upper ends of the first
heating bars are connected
to the electrical connection portion 1416c, and lower ends of the first
heating bars are
connected to the first electrode 1413c; and the width of each heating bar
ranges from 0.1 mm to
0.6 mm, and the thickness thereof ranges from 0.02 mm to 0.2 mm. In some
embodiments, the
second heating element 1415c may include several second heating bars
distributed in the
longitudinal direction of the inner wall surface of the porous body 1411c at
intervals and in
parallel, and the second heating bars form second heating circuits distributed
at intervals and in
parallel, where upper ends of the second heating circuits are connected to the
electrical
CA 03203877 2023- 6- 29 34
connection portion 1416c, and lower ends of the second heating circuits are
connected to the
second electrode 1414c.
[0134] In some embodiments, resistivities of the first heating
element 1412c and the
second heating element 1415c are greater than resistivities of the first
electrode 1413c, the
second electrode 1414c, and the electrical connection portion 1416c.
Preferably, the resistivity
of the former is more than 20 times of that of the latter. In some
embodiments, the first heating
element 1412c and the second heating element 1415c may be made of a material
such as
nickel-chromium alloy, iron-chromium-aluminum alloy, or silver-palladium
alloy, which may
be formed in a manner of silk-screening or printing heating element slurry on
an inner surface
of the green body of the porous body and then sintering the slurry. It may be
understood that,
circuits of the first heating element 1412c and the second heating element
1415c are not limited
to those shown in the figure, and may be other suitable patterns.
[0135] In some embodiments, the second sealing ring 143c may
include a first via 1431c, a
second via 1432c, and two protruding ribs 1433c. Preferably, a connecting line
of the first via
1431c and the second via 1432c is perpendicular to and intersects a connecting
line of the two
protruding ribs 1433c. In this way, when the second sealing ring 143c matches
the lower end of
the porous body 1411c, the first via 1431c and the second via 1432c directly
face the first
electrode 1413c and the second electrode 1414c respectively. The first via
1431c and the
second via 1432c are respectively provided for upper ends of the first
electrode column 15c and
the second electrode column 16c to run through, so that the upper ends of the
first electrode
column 15c and the second electrode column 16c are in electrical contact and
conducted with
the first electrode 1413c and the second electrode 1414c respectively. Based
on this, when the
first electrode column 15c and the second electrode column 16c are
respectively conducted
with a positive electrode and a negative electrode of a battery device, a
current flowing out of
the positive electrode of the battery device flows back to the negative
electrode of the battery
device after flowing through the first electrode column 15c, the first
electrode 1413c, the first
heating element 1412c, the electrical connection portion 1416c, the second
heating element
1415c, the second electrode 1414c, and the second electrode column 16c
sequentially, to
implement a process that the first heating element 1412c and the second
heating element 1415c
generate heat. When compared with a conduction process with the assistance of
components
such as a bottom base and a vent tube in the related art, in an electrical
loop of this heating
process, selection of materials of the bottom base and the vent tube is more
flexible and the
CA 03203877 2023- 6- 29 35
components may be made of non-metal materials, so that costs of the entire
vaporizer lc may
be significantly reduced. In addition, automated production of the vaporizer
lc becomes more
convenient.
[0136] FIG. 21 shows a vaporization main body 10d in some
embodiments of the present
invention. The vaporization main body 10d may be an alternative of the
vaporization main
body 10b and may include a bottom base lid, a vent tube 12d, a housing 13d, a
vaporization
assembly 14d, an electrode column 15d, and an insulating sealing ring 16d that
are coaxially
assembled. Structures of the bottom base 11d, the vent tube 12d, the housing
13d, the electrode
column 15d, and the insulating sealing ring 16d may be the same as those of
the bottom base
11b, the vent tube 12b, the housing 13b, the electrode column 15b, and the
insulating sealing
ring 16b of the vaporization main body 10b respectively, and details are not
described herein
again. Differences between the two structures mainly lie in that: (1) The
first electrode claw
17b and the second electrode claw 18b in the vaporization main body 10b are
omitted in the
vaporization main body 10d. (2) The vaporization assembly 14d is different
from the
vaporization assembly 14b.
[0137] The vaporization assembly 14d may include a
longitudinally arranged cylindrical
vaporization core 141d, a first sealing ring 142d sleeved on an upper end of
the vaporization
core 141d, and a second sealing ring 143d sleeved on a lower end of the
vaporization core
141d. A structure of the vaporization core 141d is the same as that of the
vaporization core
141b of the vaporization assembly 14b and may include a cylindrical porous
body 1411d, a
heating element 1412d arranged on an inner wall surface of the porous body
1411d, a first
electrode 1413d arranged on an upper end surface of the porous body 1411d and
electrically
connected to an upper end of the heating element 1412d, and a second electrode
1414d
arranged on a lower end surface of the porous body 1411d and electrically
connected to a lower
end of the heating element 1412d. Main differences between the two structures
lie in that: (1)
The first sealing ring 142d is conductive, namely, has both sealing and
conductive functions,
and may be made of conductive silicone. (2) The second sealing ring 143d is a
composite
sealing ring, where an inner ring part is conductive to be electrically
connected to the electrode
column 15d; and an outer ring part is not conductive to electrically insulate
the conductive
inner ring part from the conductive bottom base 11d.
[0138] Based on the structure differences, in the vaporization
main body 10d, the first
electrode 1413d is electrically connected to the vent tube 12d through the
first sealing ring
CA 03203877 2023- 6- 29 36
142d, and the second electrode 1414d is electrically connected to the
electrode column 15d
through the conductive inner ring part of the second sealing ring 143d.
Compared with the
vaporization main body 10b, no electrode claw extends into the airflow
channel, so that
interference to airflows in the airflow channel during a flowing process is
reduced, and flowing
of the airflows becomes smoother. In addition, after the first electrode claw
17b and the second
electrode claw 18b are omitted, manufacturing costs can be reduced, assembly
steps can be
reduced, and the product stability can be improved.
[0139] While the invention has been illustrated and described in
detail in the drawings and
foregoing description, such illustration and description are to be considered
illustrative or
exemplary and not restrictive. It will be understood that changes and
modifications may be
made by those of ordinary skill within the scope of the following claims. In
particular, the
present invention covers further embodiments with any combination of features
from different
embodiments described above and below. Additionally, statements made herein
characterizing the invention refer to an embodiment of the invention and not
necessarily all
embodiments.
