BACKGROUND
[0003] An electronic vaporization device is configured to heat and vaporize
a vaporizable
liquid medium, to generate inhalable aerosols. In an electronic vaporization
device in the
related technology, a vaporization core is generally manufactured using a
porous ceramic. A
lead of such porous ceramic vaporization core generally needs to pass through
the porous
ceramic, causing the porous ceramic to change in the internal structure and to
be prone to cracks.
In addition, when a lead electrode is energized and wired, long circuit wiring
increase
manufacturing difficulty and production costs of the electronic vaporization
device.

[0033] FIG. 1 and FIG. 2 show an electronic vaporization device 1 in some
embodiments
of the present disclosure. The electronic vaporization device 1 includes a
vaporizer 100 and a
power supply device 200 matched with and connected to the vaporizer 100. The
power supply
device 200 is configured to supply power to the vaporizer 100 and can control
operations such
as ON and OFF of the entire electronic vaporization device 1. The vaporizer
100 is configured
to accommodate a liquid medium and heat and vaporize the liquid medium to
generate aerosols
after energized. In some embodiments, both the vaporizer 100 and the power
supply device
200 may have a roughly cylindrical structure, and may be mechanically and
electrically
connected in the axial direction. Further, the vaporizer 100 and the power
supply device 200
may be detachably connected together in a threaded connection manner. It may
be understood
that in other embodiments, the vaporizer 100 and the power supply device 200
may
alternatively be connected together in other detachable manners such as
magnetic connection,
snap-fit connection. Alternatively, the vaporizer 100 and the power supply
device 200 may be
connected together in a non-detachable manner. In addition, the cross-
sectional shape of the
vaporizer 100 and/or the power supply device 200 is not limited to being
circular, and may also
be in other shapes such as ellipse, racetrack, or rectangle.
[0034] As shown in FIG. 3 to FIG. 5, the vaporizer 100 may include a liquid
storage and
vaporization body 10 and a mouthpiece body 20 disposed at the upper end of the
liquid storage
and vaporization body 10. A liquid storage cavity 110 for accommodating a
liquid medium and
an output channel 120 isolated from the liquid storage cavity 110 and
configured to deliver
aerosols are formed in the liquid storage and vaporization body 10. The
mouthpiece body 20
is blocked at the upper end of the liquid storage cavity 110, and has a vaping
channel 210
communicated with the output channel 120 formed therein.
Date Recue/Date Received 2023-07-13
[0035] Specifically, the mouthpiece body 20 may include a mouthpiece 21.
The vaping
channel 210 is formed in the mouthpiece 21 in the longitudinal direction and
may be disposed
coaxially with the mouthpiece 21. In some embodiments, the mouthpiece 21 may
be made of
a hard material such as plastic, to improve structural stability of the vaping
channel 210. Further,
the mouthpiece 21 may include a blocking part 211 located at the lower part
and a mouthpiece
part 212 at the upper part. The mouthpiece part 212 may have a flat shape. The
flat design can
better fit lips, and can better gather vapor to improve vaping experience. The
blocking part 211
is inserted in an opening at the upper end of the liquid storage and
vaporization body 10, to
sealingly block the upper end of the liquid storage cavity 110. In some
embodiments, the
mouthpiece body 20 may further include a seal member 22 fitted on the blocking
part 211.
[0036] The seal member 22 may be made of an elastic material such as silica
gel. The seal
member 22 is disposed between the outer wall surface of the blocking part 211
and the cavity
wall surface of the upper end of the liquid storage cavity 110 in a sealed
manner.
[0037] In some embodiments, the mouthpiece body 20 may be detachably
connected to the
upper end of the liquid storage and vaporization body 10. In this way, the
liquid medium can
be added to the liquid storage cavity 110 by detaching the mouthpiece body 20
from the liquid
storage and vaporization body 10, to prolong the service life of the vaporizer
100. In addition,
parts of the mouthpiece body 20 and/or the liquid storage and vaporization
body 10 can be
replaced separately, to reduce costs. In other embodiments, the mouthpiece
body 20 and the
liquid storage and vaporization body 10 may alternatively be connected
together in a non-
detachable manner.
[0038] The liquid storage and vaporization body 10 may include a shell 11,
a vent tube 12,
a vaporization assembly 13, an electrode column 14 and abase 16. The vent tube
12 is disposed
in the shell 11 in the longitudinal direction and may be disposed coaxially
with the shell 11.
The vent tube 12 may be tubular. The inner wall surface of the vent tube 12
defines an output
channel 120. An annular liquid storage cavity 110 is defined between the outer
wall surface of
the vent tube 12 and the inner wall surface of the shell 11. The upper end of
the vent tube 12
may be inserted into the mouthpiece body 20. Specifically, the upper end of
the vent tube 12
may penetrate through the seal member 22 and be inserted into the mouthpiece
21. The seal
member 22 is configured to sealingly wrap on the vent tube 12. The mouthpiece
21 is used for
ensuring the reliability of the connection between the vent tube 12 and the
mouthpiece body
20.

[0039] The vaporization assembly 13 is accommodated in the vent tube 12 and
may be
disposed coaxially with the vent tube 12. The vaporization assembly 13
includes a vaporization
core 130. The vaporization core 130 includes a liquid absorbing body 131 and a
heating element
132 in contact with the liquid absorbing body 131. The liquid absorbing body
131 is in fluid
communication with the liquid storage cavity 110, and is configured to absorb
the liquid
medium from the liquid storage cavity 110 and deliver the liquid medium to the
heating element
132. Specifically, in this embodiment, the liquid absorbing body 131 is a
porous ceramic, and
can absorb the liquid medium from the liquid storage cavity 110 through
infiltration and
capillary effect of an internal microporous structure of the liquid absorbing
body 131. The
liquid absorbing body 131 may be cylindrical, and is internally provided with
a vaporization
cavity 1310 running through the liquid absorbing body in the longitudinal
direction. The
vaporization cavity 1310 is communicated with the lower end of the output
channel 120 and
may be disposed coaxially with the output channel 120.
[0040] It may be understood that in other embodiments, the liquid absorbing
body 131 may
alternatively be made of other porous materials, not limited to a porous
ceramic material.
[0041] The heating element 132 may be a heating film, and may be formed on
a blank of
the liquid absorbing body 131 by silk screen printing, printing, spraying or
the like, then
sintered together with the liquid absorbing body 131 and formed.
Alternatively, the heating
element 132 may be an independently formed metal heating sheet or metal
heating wire. The
heating element 132 includes at least one heating track 1321 and two end
surface electrodes
1322 and 1323 connected to two poles of the at least one heating track 1321.
The at least one
heating track 1321 may be disposed in the inner wall surface of the liquid
absorbing body 131
to generate heat after energized, to heat and vaporize the liquid medium
adsorbed by the liquid
absorbing body 131. The two end surface electrodes 1322 and 1323 are
respectively disposed
on the upper end surface and the lower end surface ofthe liquid absorbing body
131 for external
connection of an external power supply. Further, in other embodiments, the
heating element
132 may also include two connection electrodes 1324 and 1325. The two
connection electrodes
1324 and 1325 are respectively disposed at the upper and lower ends of the
inner wall surface
of the liquid absorbing body 131. The upper and lower ends of the heating
track 1321 are
connected to the two end surface electrodes 1322 and 1323 through the two
connection
electrodes 1324 and 1325, respectively. It may be understood that in other
embodiments, the
heating element 132 may alternatively not include the two connection
electrodes 1324 and
7
Date Recue/Date Received 2023-07-13
1325. In other words, the upper and lower ends of the heating track 1321 may
alternatively be
directly connected to the two end surface electrodes 1322 and 1323.
[0042] In this embodiment, the heating element 132 includes three parallel
heating tracks
1321. The three heating tracks 1321 are evenly arranged at intervals in the
circumferential
direction of the liquid absorbing body 131. This is beneficial to uniformly
heat the liquid
medium adsorbed by the liquid absorbing body 131. Each heating track 1321
extends in the
axial direction of the heating element 132 in a non-linear manner, such as
extending along a
curved or zigzag path, to increase the heating area of the heating track 1321.
The two
connection electrodes 1324 and 1325 are cylindrical, and the two end surface
electrodes 1322
and 1323 are thin annular discs. The upper end of the connection electrode
1324 is connected
to the end surface electrode 1322, and the lower end is connected to the upper
ends of the three
heating tracks 1321. The lower end of the connection electrode 1325 is
connected to the end
surface electrode 1323, and the upper end is connected to the lower end of the
three heating
tracks 1321.
[0043] It may be understood that in other embodiments, the quantity of the
heating tracks
1321 may be one, two, or three or more, and/or, the heating tracks 1321 may
also extend along
a straight line.
[0044] In some embodiments, the vaporization core 130 may further include a
liquid guide
cotton 137 fitted outside the liquid absorbing body 131 and in contact with
the liquid absorbing
body 131. The liquid medium in the liquid storage cavity 110 is adsorbed by
the liquid guide
cotton 137 and distributed in the liquid guide cotton 137, and then delivered
to the liquid
absorbing body 131. In this way, the liquid guide is faster and more uniform.
[0045] The base 16 is disposed at the lower end of the shell 11 and blocks
the lower end of
the liquid storage cavity 110. In some embodiments, both the base 16 and the
vent tube 12 are
electrically conductive. The end surface electrode 1322 can be directly or
indirectly electrically
connected to the vent tube 12, to electrically connected to the base 16. The
electrode column
14 is inserted into the base 16 in the longitudinal direction and is
electrically insulated from the
base 16. The end surface electrode 1323 is directly or indirectly electrically
connected to the
electrode column 14.
[0046] In some embodiments, the base 16 may be integrally formed by a metal
material,
and may be fixed in the shell 11 by riveting or the like. The base 16 may
include a base part
8
Date Recue/Date Received 2023-07-13
161, an insertion part 162 extending upward from the upper end surface of the
base part 161,
and a connecting part 163 extending downward from the lower end surface of the
base part 161.
The base part 161 may be cylindrical. The upper end surface of the base part
161 may abut
against the lower end surface of the shell 11. The outer diameter of the base
part 161 may be
the same as the outer diameter of the lower end of the shell 11. The
connecting part 163 may
be cylindrical. The outer wall surface of the connecting part 163 is provided
with a threaded
structure for threaded connection with the power supply device 200. The outer
diameter of the
connecting part 163 may be smaller than the outer diameter of the base part
161. At least one
air inlet hole 1630 may also be formed in the side wall that is at the upper
part of the connecting
part 163 and that is not provided with the threaded structure, to allow
outside air to enter the
vaporization cavity 1310. In this embodiment, there are a plurality of air
inlet holes 1630, and
the plurality of air inlet holes 1630 are evenly arranged at intervals in the
circumferential
direction of the connecting part 163.
[0047] The
insertion part 162 may be cylindrical and inserted into the lower part of the
shell 11. At least part of the outer peripheral surface of the insertion part
162 is sealingly fitted
to the inner wall surface of the shell 11, to sealingly block the lower end of
the liquid storage
cavity 110. Specifically, in this embodiment, the insertion part 162 may
include a body part
1621 and a sealing boss 1622 extending outward from the body part 1621. The
outer wall
surface of the body part 1621 may be in a clearance fit with the inner wall
surface of the shell
11. The body part 1621 has a longer length in the axial direction, so that
force required for
mounting the base 16 into the shell 11 is reduced. The sealing boss 1622 is in
an interference
fit with the inner wall surface of the shell 11. The sealing effect is
enhanced by the interference
fit. The axial length of the sealing boss 1622 is short, so that force
required for mounting the
base 16 into the shell 11 is reduced while sealing performance is ensured. In
addition, the
sealing boss 1622 may be disposed on the top of the body part 1621 or close to
the top of the
body part 1621, so that less liquid medium penetrates between the outer wall
surface of the
insertion part 162 and the inner wall surface of the shell 11, thereby
achieving a better liquid
leakage prevention effect. A guide bevel 1623 may also be formed at the upper
end of the
sealing boss 1622. The outer diameter of the guide bevel 1623 gradually
decreases from bottom
to top, and the outer diameter of the upper end of the guide bevel 1623 is
smaller than the inner
diameter of the shell 11, so that the sealing boss 1622 can be easily guided
into the shell 11. It
may be understood that in other embodiments, the outer wall surface of the
body part 1621 may
alternatively be in a transition fit with the inner wall surface of the shell
11. In some other
9
Date Recue/Date Received 2023-07-13
embodiments, the sealing boss 1622 may alternatively be located at the middle
or lower part of
the body part 1621.
[0048] Further, the insertion part 162 may further include a joint part
1624 connected to
the lower end of the body part 1621. The outer wall surface of the joint part
1624 may be in an
interference fit with the inner wall surface of the shell 11. This can further
improve the liquid
leakage prevention effect, and can make fixation of the insertion part 162 in
the shell 11 more
reliable. In addition, the insertion part 162 is located at the opening of the
shell 11, and has
little influence on the force required for mounting the base 16 into the shell
11. It may be
understood that in other embodiments, the outer wall surface of the joint part
1624 and the
inner wall surface of the shell 11 may alternatively be in a transition fit or
a clearance fit.
[0049] In some embodiments, a heat insulation space 1610 may also be formed
on the base
16. The heat insulation space 1610 can play a role of heat insulation and heat
preservation, to
reduce heat transferred outward by the base 16 and reduce heat loss.
[0050] In this embodiment, the heat insulation space 1610 is an annular
groove, which is
formed by radial inward depression of the outer peripheral surface of the base
part 161. Because
the outer diameter of the base part 161 is the largest, the provision of the
heat insulation space
1610 on the base part 161 enables the heat insulation space 1610 to have large
volumetric space,
so as to improve heat insulation effect and reduce heat transferred to the
connecting part 163,
thereby reducing heat transferred to the power supply device 200. It may be
understood that in
other embodiments, the heat insulation space 1610 may alternatively be in
other shapes, such
as a shape of petals arranged at intervals.
[0051] In some other embodiments, the heat insulation space 1610 may
alternatively be
completely or partially formed on the insertion part 162 or the connecting
part 163. In addition,
the heat insulation space 1610 may also be filled with a heat insulation
material to further
improve the heat insulation effect.
[0052] In some embodiments, the liquid storage and vaporization body 10 may
also include
a fixing sleeve 17. The fixing sleeve 17 is cylindrical and fitted at the
lower end of the shell 11
and outside the base part 161. This can strengthen the fixation between the
she 11 and the
base 16, and can also seal the heat insulation space 1610.
Date Recue/Date Received 2023-07-13
[0053] The vent tube 12 may be integrally formed by a metal material, and
may include a
first tube section 121 and a second tube section 122 connected to the lower
end of the first tube
section 121. Both the inner diameter and the outer diameter of the first tube
section 121 are
smaller than the inner diameter and the outer diameter of the second tube
section 122. The outer
diameter of the first tube section 121 is small, so that the liquid storage
cavity 110 formed
between the outer wall surface of the first tube section 121 and the inner
wall surface of the
shell 11 has a larger liquid storage space. The lower end of the second tube
section 122 is
inserted in the base 16, and the outer wall surface of the second tube section
122 is in electrical
contact with the inner wall surface of the base 16. It may be understood that
in other
embodiments, the vent tube 12 and/or the base 16 may alternatively be made of
an electrically
conductive or insulating material, and then coated with an electrically
conductive layer on a
required electrically conductive part to achieve an electrically conductive
function.
[0054] The vaporization core 130 is accommodated in the second tube section
122, and at
least one liquid inlet 1220 is formed in the side wall of the second tube
section 122, to enable
the liquid medium in the liquid storage cavity 110 to flow into the
vaporization core 130
through the at least one liquid inlet 1220. In this embodiment, there are a
plurality of liquid
inlets 1220, and the plurality of liquid inlets 1220 are evenly arranged at
intervals in the
circumferential direction of the second tube section 122, to facilitate
uniform and sufficient
liquid supply to the liquid absorbing body 131. The inner diameter of the
second tube section
122 may be slightly smaller than the outer diameter of the liquid guide cotton
137, to enable
the second tube section 122 to tightly clamp the liquid guide cotton 137. In
this way, the
vaporization core 130 can be fixed, and liquid leakage can be reduced through
sealing. It may
be understood that in other embodiments, the inner diameter of the second tube
section 122
may alternatively be equal to or greater than the outer diameter of the liquid
guide cotton 137.
[0055] The upper end of the second tube section 122 has a conductive end
surface 1221.
The conductive end surface 1221 directly or indirectly abuts against and is
electrically
connected to the end surface electrode 1322. In this embodiment, the
conductive end surface
1221 directly abuts against and is electrically connected to the end surface
electrode 1322.
[0056] In some embodiments, the vaporization assembly 13 further includes a
conductive
connector 135. The electrode column 14 is electrically connected to the end
surface electrode
1323 through the conductive connector 135. Further, the electrode column 14
has a conductive
end surface 1411. The conductive connector 135 is disposed between the
conductive end
11
Date Recue/Date Received 2023-07-13
surface 1411 and the end surface electrode 1323. The conductive connector 135
may include a
body part 135 1 and at least one elastic arm 1352 connected to the body part
1351. The at least
one elastic arm 1352 may be in elastic and electrical contact with the
conductive end surface
1411 or the end surface electrode 1323. The conductive connector 135 may
produce certain
elastic deformation in the longitudinal direction, to cause the vaporization
core 130 to produce
certain elastic floating in the longitudinal direction. As a result, a
reliable electrical connection
is still formed between the conductive end surface 1411 and the end surface
electrode 1323 in
the case of low product uniformity. In addition, due to the elasticity of the
conductive connector
135, the porous ceramic liquid absorbing body can be prevented from being
damaged during
installation.
[0057] Specifically, in this embodiment, the outer wall surface of the
electrode column 14
protrudes outward to form a circular flange 1412. The upper end surface of the
flange 1412
forms a conductive end surface (1411). The center part of the top surface of
the electrode
column 14 may extend downwards to form a center hole 140. The center hole 140
is located
under the vaporization cavity 1310 and can receive and accommodate certain
leaked liquid or
condensate. The lower end of the center hole 140 has a bottom wall 143. The
bottom wall 143
seals the lower end of the center hole 140, to prevent leakage of the leaked
liquid or condensate
in the center hole 140 to the outside. A circular vent gap 144 is formed
between the outer wall
surface of the electrode column 14 and the inner wall surface of the base 16.
The air inlet hole
1630 is communicated with vaporization cavity 13 10 through the vent gap 144.
There is a
spacing between the upper end surface of the electrode column 14 and the lower
end surface
of the vaporization core 130. The spacing can play a role of heat insulation
and air circulation.
[0058] The spacing can prevent the vaporization core 130 from being in
direct contact with
the electrode column 14, and prevent heat of the vaporization core 130 from
being directly
transferred to the electrode column 14, thereby achieving heat insulation. In
addition, the
spacing also communicates the vent gap 144 with the vaporization cavity 1310.
[0059] As shown in FIG. 6, the conductive connector 135 may be integrally
formed with a
metal material such as phosphor copper or 316 stainless steel. The surface of
the conductive
connector 135 may also be provided with a coating layer such as a gold coating
or a silver
coating, to improve conductivity.

[0060] The body part 1351 is cylindrical and is fitted on the upper part of
the electrode
column 14. The lower end of the body part 1351 abuts against the conductive
end surface 1411
and is in electrical contact with the conductive end surface 1411. The inner
wall surface of the
body part 1351 is in electrical contact with the outer wall surface of the
electrode column 14.
In this way, the fixation of the conductive connector 135 on the electrode
column 14 is more
reliable, and the electrical connection between the conductive connector 135
and the electrode
column 14 is more reliable. A flare structure 1353 may also be provided at the
bottom of the
body part 1351. The diameter of the flare structure 1353 gradually decreases
from bottom to
top, to facilitate the fitting of the body part 1351 onto the electrode column
14. In addition, the
outer surface of the upper end of the electrode column 14 may also be formed
with a guide
bevel, to facilitate the fitting of the body part 1351 onto the electrode
column 14.
[0061] Preferably, there are a plurality of elastic arms 1352. The
plurality of elastic arms
1352 are evenly arranged at intervals in the circumferential direction of the
body part 1351.
Each elastic arm 1352 includes a conducting part 1355 configured to
elastically abut against
and be electrically connected to the end surface electrode 1323 and a
connecting arm 1356
connecting the conducting part 1355 and the body part 1351. In some
embodiments, the
quantity of the elastic arms 1352 may range from two to four. This can ensure
the width of the
elastic arms 1352 to enable the elastic arms 1352 to be in electrical contact
with the end surface
electrode 1323 more stably, and can meet requirements of a manufacturing
process and
facilitate manufacturing. Specifically, in this embodiment, the quantity of
the elastic arms 1352
is two.
[0062] Further, in this embodiment, the connecting arm 1356 is sheet-shaped
and has good
elasticity, and may extend upward from the top surface of the body part 135 1
and obliquely
toward the center of the body part 1351. The conducting part 1355 may roughly
have a spoon-
shaped structure, and may be formed by the end of the connecting arm 1356 away
from the
body part 1351 bending toward the inside of the body part 1351, that is, the
bowl of the spoon
faces the inside of the body part 1351. The bevel of the spoon-shaped
structure has a guiding
effect, and the bottom of the spoon is an arc surface, to be in better contact
with the end surface
electrode 1323. It may be understood that in other embodiments, the connecting
arm 1356 may
alternatively be inclined away from the center of the body part 1351, and/or,
the bowl of the
scoop of the conducting part 1355 may alternatively face the outside of the
body part 1351.

[0063] It may be understood that in other embodiments, the conductive end
surface 1411
may also be formed on the upper end surface of the electrode column 14. In
some other
embodiments, the body part 1351 may abut against and be electrically connected
to the end
surface electrode 1323, and the elastic arm 1352 may elastically abut against
and be electrically
connected to the conductive end surface 1411.
[0064] As shown in FIG. 3 to FIG. 5, the electrode column 14 and the base
16 may be
insulatingly and sealingly connected through an insulating sleeve 15.
Specifically, the
insulating sleeve 15 may be made of an insulating material such as silica gel
or plastic. The
insulating sleeve 15 is disposed in the connecting part 163 in the
longitudinal direction. The
electrode column 14 is disposed in the insulating sleeve 15 in the
longitudinal direction. The
lower end surface of the flange 1412 may abut against the upper end surface of
the insulating
sleeve 15. In some embodiments, the insulating sleeve 15 may be annular with
an opening on
one side. A through hole 150 is formed in and runs through the insulating
sleeve 15 in the
longitudinal direction. The electrode column 14 is inserted into the through
hole 150. A slot
151 is formed on one circumferential side of the insulating sleeve 15. The
slot 151 runs through
the upper and lower sides of the insulating sleeve 15, to facilitate the
installation of the
electrode column 14 into the insulating sleeve 15.
[0065] Further, at least one vent passage 152 may also be formed in the
insulating sleeve
15. The at least one vent passage 152 communicates the vent gap 144 with the
outside. In one
embodiment, the vent passage 152 may be used for inflow of air, that is,
allowing outside air
to enter the vent gap 144. In this case, an air inlet hole 1630 may or may not
be provided on
the base 16. In another embodiment, the vent passage 152 may be configured to
communicate
the vent gap 144 with an airflow sensor in the power supply device 200, to
enable the power
supply device 200 to be turned on through the airflow sensor to supply power
to the vaporizer
100 during vaping.
[0066] In this embodiment, there are a plurality of vent passages 152
evenly arranged at
intervals in the circumferential direction of the insulating sleeve 15. Each
vent passage 152
includes a vent 1521 formed in the upper end surface of the insulating sleeve
15 and a vent
groove 1522 communicated with the vent 1521 and formed in the longitudinal
direction in the
inner wall surface of the insulating sleeve 15. It may be understood that in
other embodiments,
the vent passage 152 may alternatively be formed in the outer wall surface of
the insulating
sleeve 15.
