ATOMIZING DEVICE, ATOMIZING ASSEMBLY, AND MANUFACTURING PROCESS
OF ATOMIZING ASSEMBLY
FIELD
[1] The present invention relates to the technical field of electronic
cigarette sets, and
more specifically, to an atomizing device, an atomizing assembly, and a
manufacturing
process of the atomizing assembly.
BACKGROUND
[2] The electric heating atomization technology is to use the electric
energy to heat
atomizable liquid to make it reach the boiling point to produce aerosol to be
mixed with air.
[31 The atomizing core is the core part of the atomizer, and the key of
the atomizing
core is the matching and consistency of the liquid conducting material and the
heating
material. The heating member and the liquid conducting material should be well
bonded.
While if the heating member meets the resistance requirement, it generally has
a poor
strength and is prone to deformation.
[4] Different from other electric heating methods, due to the fact that
the electronic
atomizing device is limited by the volume and the usage scenario, the
characteristics of the
use of the device are: the working time of each time is short (since the
smoking of the user
usually is generally within 5 seconds), and the use frequency is high (may be
used more than
100 to 200 times a day). The principle of the electronic atomizing device is
to heat the
atomizable liquid to evaporate it instantaneously at a high temperature.
Therefore, it is
required that the working of the heating member can reach the boiling point of
the atomizable
liquid instantaneously. The main components of the atomizable liquid are
propylene glycol
and glycerol, and the boiling point of the mixed liquid is about 230 degrees
Celsius.
[51 However, limited to these conditions, the material selection of the
heating member
is generally thin (generally a round wire with a diameter of 0.2 mm, that is,
a cross-sectional
area of 0.0314 mm2), so that the strength of the heating member is weak, and
it is difficult to
have a supporting force to ensure the contact between the heating member and
the liquid
conducting cotton. Therefore, the wire is often wound into a spiral shape in
the industry,
but there is still a problem of poor contact, and dry burning is easy to
occur.

DETAILED DESCRIPTION
[54] For better understanding of the technical features, objects and
effects of the
present invention, the specific embodiments of the present invention will be
described in
detail with reference to the accompanying drawings.
[55] An atomizing device in a preferred embodiment of the present invention
includes
an atomizer and a battery assembly. The atomizer includes a housing, and a
liquid storage
cavity and an atomizing assembly 10 that are arranged in the housing. The
liquid storage
cavity is configured to store an atomizable medium. The atomizing assembly 10
can adsorb
the atomizable medium. When the atomizing assembly 10 is electrified by the
battery
assembly, the atomizable medium on the atomizing assembly 10 can be heated to
generate
aerosols to flow out.
[56] As shown in Fig. 1 to Fig. 7, the atomizing assembly 10 includes a
first liquid
conducting member 11, a heating assembly, and an electrode. The first liquid
conducting
member 11 is made of a flexible material. Generally, the first liquid
conducting member 11
is provided with holes, or is made of woven material, and is configured to
adsorb the
atomizable medium. The heating assembly is fixed to the first liquid
conducting member 11
6
8610870
Date Recue/Date Received 2023-07-21
through sewing, and the electrode is electrically connected to the heating
assembly. When
the electrode is energized, the heating assembly is energized to generate heat
to atomize the
atomizable medium on the first liquid conducting member 11.
[57] In some embodiments, the first liquid conducting member 11 includes an
atomizing surface A and an liquid inlet surface B. Generally, the atomizing
surface A and
the liquid inlet surface B are located on two opposite sides of the first
liquid conducting
member 11, respectively. The atomizable medium enters the first liquid
conducting member
11 from the liquid inlet surface B, and the adsorbed atomizable medium is
heated to generate
aerosol when the heating assembly is powered on, then the generated aerosol
flows outward
from the atomizing surface A by airflow, so that the liquid inlet and the
atomization are not
interfered. Preferably, the atomizing surface A is provided with a concave-
convex structure
that allows the heating assembly to be embedded in the surface of the first
liquid conducting
member 11, increasing the contact area between the heating assembly and the
first liquid
conducting member 11.
[58] As shown in Fig. 8 and Fig. 9, the first liquid conducting member 11
may include
one layer of liquid conducting layer 111, or may include more than one layer
of liquid
conducting layer 111 stacked in layers. When multiple layers of liquid
conducting layers
111 are adopted, gaps are reserved between the various layers, which can store
part of the
atomizable liquid to improve the use effect. Meanwhile, the multi-layer first
liquid
conducting member 11 is sewn into a whole structure, which is also convenient
for
subsequent assembly. Further, the multi-layer structure may be made of
different materials,
so that some requirements can be taken into account, for example, the liquid
inlet side needs
to be made of a material with fast liquid conduction and good oil locking, and
the part that is
tightly attached to the second wire 13 needs to be made of a material with a
high-temperature
resistant, while the problem can be well solved by adopting the multi-layer
first liquid
conducting member 11.
[59] When the first liquid conducting member 11 is a multi-layer liquid
conducting
layer 111, the liquid conducting layer 111 of the atomizing surface A of the
first liquid
conducting member 11 may be made of one of the materials of linen cotton or
aramid fiber
woven fabric, or may be formed by weaving the above several materials, or may
be made of
some high-temperature resistant mixed materials.

[60] In addition, when the first liquid conducting member 11 is a multi-
layer liquid
conducting layer 111, the liquid conducting layer 111 of the liquid inlet
surface B of the first
liquid conducting member 11 may be made of one or a combination of a non-woven
fabric, a
grating, and a mesh cotton. Further, the liquid inlet surface B is provided
with grooves or
mesh holes, so that the liquid conduction is faster, ensuring a timely liquid
supply during
atomization, and avoiding the dry burning due to insufficient liquid supply.
[61] The first liquid conducting member 11 may be used in combination with
other
liquid conducting cotton. Preferably, the atomizing assembly 10 further
includes a second
liquid conducting member attached to the first liquid conducting member 11,
and the second
liquid conducting member is located on the side opposite the atomizing surface
A.
[62] The second liquid conducting member may be a liquid conducting cotton,
a
porous ceramic, or a liquid storage cotton or the like. The combined shape of
the second
liquid conducting member and the first liquid conducting member 11 may be a
flat plate
shape, or may be curled into a columnar shape, a tubular shape, or a curved
shape.
[63] Further, as shown in Fig. 1 and Fig. 2, in a first embodiment, the
heating assembly
includes a first wire 12 and a second wire 13 that are flexible. Preferably,
the second wire
13 is made of electrically conductive material. The first wire 12 and the
second wire 13 are
respectively sewn onto the first liquid conducting member 11 from two opposite
sides of the
first liquid conducting member 11 and interwoven with each other, and are
respectively fixed
to the first liquid conducting member 11 from two sides.
[64] Further, the electrodes include a first electrode 15 and a second
electrode 16 that
are respectively electrically connected to the heating assembly, and
preferably, connected to
two ends of the heating assembly, and connected to the battery assembly
through contacts or
conducting wires to supply power to the heating assembly. In other
embodiments, the
electrodes may include a plurality of electrodes that may be connected to the
battery
assembly respectively.
[65] Correspondingly, in the embodiment, the side where the second wire 13
is located
is the atomizing surface A, and the side where the first wire 12 is located is
the liquid inlet
surface B. The atomizable medium enters the first liquid conducting member 11
from the
side where the first wire 12 is located. When the second wire 13 made of a
conductive
material is energized, the adsorbed atomizable medium is heated to generate
aerosol, which
8
8610870
Date Recue/Date Received 2023-07-21
flows outward from the side where the second wire 13 is located under the
action of the
airflow. Of course, when the first wire 12 is made of a conductive material
and the second
wire 13 is made of a non-conductive material, the liquid inlet surface B and
the atomizing
surface A are exchanged. Or alternatively, both the first wire 12 and the
second wire 13 are
made of a conductive material, and both sides are atomized simultaneously, and
the liquid
may be entered from an end portion or a lateral side.
[66] Further, in some embodiments, the first wire 12 may be made of a non-
conductive
material, and of course, the first wire 12 may also be made of a conductive
material. When
the first wire 12 is made of a conductive material, the resistance of the
second wire 13 is less
than the resistance of the first wire 12.
[67] According to the sewing principle of a sewing machine, the first wire
12 and the
second wire 13 with different resistances on the two sides are interwoven to
form an integral
structure with the first liquid conducting member 11. At least one of the
first wire 12 and
the second wire 13 can generate heat. The second wire 13 that can generate
heat is fixed to
the first liquid conducting member 11, which can ensure the contact between
the second wire
13 and the first liquid conducting member 11, and is conducive to heating and
atomizing, so
that the problem of dry burning is avoided, and mass production can be
realized.
[68] According to the sewing principle of the sewing machine, one of the
wires is
changed into a conductive heating wire and the heating wire is fixed to the
first liquid
conducting member 11, so that the heating wire is assisted by an object and
not easily
separated from the liquid conducting substrate, meanwhile, large-batch
production can be
achieved, and the production cost is low.
[69] Further, the heating assembly is fixed by sewing and has a good
contact with the
first liquid conducting member 11, so that the loosening is avoided. The first
wire 12 and
the second wire 13 can adopt thinner wires, and since the sectional areas of
the first wire 12
and the second wire 13 can be smaller than that of the prior art, the thermal
startup speed is
fast, the heat dissipation is also fast, and a lower power can be used to
drive the atomizing
assembly 10, which is more energy-saving. Large-scale production is
facilitated in the
mode that the first wire 12 and the second wire 13 are interwoven after
sewing. The
wire-shaped process generally adopts a wire drawing forming through a die
hole, and the
9
8610870
Date Recue/Date Received 2023-07-21
sizes of the first wire 12 and the second wire 13 can be controlled
accurately, which can make
the resistance of the atomizing assembly 10 more stable.
[70] Generally, the conductive material of the second wire 13 is one or a
combination
of a conductive metal alloy wire, a conductive metal fiber wire, a conductive
carbon fiber
wire, and a conductive graphite wire, which generates heat when the current is
input, so that
the second wire 13 generates heat when being energized. In some embodiments,
the second
wire 13 may adopt a round wire with the wire diameter ranging from 0.03 mm to
0.2 mm,
and preferably 0.11 mm, which is relatively proper in diameter and is not easy
to break, and
relatively thin and soft to be bent easily, and meanwhile, some requirements
of the atomizing
device on the resistance can be met. An optional material of the second wire
13 may be a
metal material such as a nickel-based alloy, a stainless steel series alloy, a
chromium-containing alloy, a titanium-containing alloy, a tungsten-containing
alloy, a
molybdenum-containing alloy, an iron-containing alloy, or a tin-containing
alloy, or may be a
non-metallic conductive material such as a carbon fiber wire or a graphite
fiber wire, or may
also be a filamentary shape twisted by one or two of an extremely fine
conductive metal wire
and an extremely fine conductive non-metallic wire. The conductive metal wire
and the
conductive non-metallic wire are relatively thin, and may be a fine wire with
a diameter of
several microns to tens of microns, which are not limited specifically.
[71] The first wire 12 used to fix the second wire 13 has a wide range of
material
selection, which may be either a conductive material or a non-conductive
material. The
wire diameter of the first wire 12 also has a wide selection, and preferably
is about 0.15 mm
with a shape of a filament.
[72] Specifically, the first liquid conducting member 11 is a liquid
conducting cotton.
After sewing, most of the second wire 13 is exposed on the atomizing surface
A, and part of
the second wire 13 is slightly sunken into the first liquid conducting member
11, so that the
liquid on the surface of the first liquid conducting member 11 can be rapidly
heated to the
boiling point to generate atomized vapor when the two ends of the second wire
13 are
energized.
[73] It can be understood that the second wire 13 may be bent, and the
bending mode
may adopt a back-and-forth bending mode or a waveform bending mode. In
addition, the
second wire 13 may also be curved, and the curved mode is not limited herein.
8610870
Date Recue/Date Received 2023-07-21
[74] Further, in order to make the area of heat radiation larger, the
heating assembly
includes several second wires 13 located on the same side of the first liquid
conducting
member 11. Preferably, the number of the second wires 13 may be two or more.
The
various second wires 13 may be interwoven to form a mesh structure as shown in
Fig. 11, or
the various second wires 13 may be arranged side by side as shown in Fig. 12,
or may also be
arranged in a combination manner of interwoven and side-by-side arrangement. A
plurality
of second wires 13 may also be bent and curved to form a mesh structure.
[75] When the second wire 13 is relatively soft in the material or
relatively thin in the
wire diameter, the interwoven position of the second wire 13 and the first
wire 12 may be
trapped in the first liquid conducting member 11 or may be flush with the
surface of the first
liquid conducting member 11.
[76] Further, as shown in Fig. 8 to Fig. 10, when the second wire 13 has a
thicker wire
diameter, such as 0.15 mm or more, the second wire 13 may be flush with the
surface of the
first liquid conducting member 11 due to its high hardness and difficulty in
bending. When
the first wire 12 is a relatively soft wire, such as a cotton thread, a linen
thread, an aramid
fiber or other flexible wire, the second wire 13 may be flush with the surface
of the first
liquid conducting member 11 without being trapped in the first liquid
conducting member 11,
or may be slightly bent.
[77] In some embodiments, the first wire 12 is made of a non-conductive
material, and
the atomizable medium enters the first liquid conducting member 11 from the
side where the
first wire 12 is located. Further, the non-conductive material of the first
wire 12 may be
cotton thread, flax, aramid fiber, glass fiber yarn, ceramic fiber yarn, or
other material with a
high temperature resistance, which is not limited herein.
[78] In addition, in other embodiments, the first wire 12 may also be made
of a
conductive material, and the resistance of the second wire 13 is smaller than
the resistance of
the first wire 12. For example, when the atomizable medium is relatively
viscous, the first
wire 12 adopts a metal wire, such that the first wire 12 also generates heat,
which is
equivalent to preheating the e-liquid to a certain extent, thereby reducing
its viscosity, and
thus accelerating its flow speed.
[79] Since most of the surface of the first wire 12 is trapped in the first
liquid
conducting member 11 or located at the liquid inlet surface B, and the first
wire 12 is in
11
8610870
Date Recue/Date Received 2023-07-21
contact with the second wire 13 of the first liquid conducting member 11, when
the first wire
12 is made of a metal material, which means the first wire 12 and the second
wire 13 are in a
parallel state, and the heat generated by the first wire 12 in the direction
close to the liquid
inlet surface B can play a role in heating the e-liquid, which is equivalent
to the effect of
preheating.
[80] The first wire 12 and the second wire 13 are arranged in parallel, so
that the
resistance of the second wire 13 needs to be smaller than the resistance of
the first wire 12,
making the power of the second wire 13 higher than that of the first wire 12.
Due to the
equal voltage of the parallel circuit, when the resistance of the second wire
13 is smaller than
that of the first wire 12, the current flowing through the second wire 13 is
larger than that of
the second wire 13, and the temperature generated by the thermal effect of
resistance of the
first wire 12 is higher.
[81] In some embodiments, as shown in Fig. 3 and Fig. 5, the first
electrode 15 and the
second electrode 16 are formed by sewing a conductive wire onto the first
liquid conducting
member 11, and it can be understood that one of the first electrode 15 and the
second
electrode 16 is formed by sewing a conductive wire onto the first liquid
conducting member
11, which is conducive to the batch and automated production of the atomizing
assembly.
[82] Further, the first electrode 15 and the second electrode 16 are
located on a same
side of the first liquid conducting member 11. Preferably, the first electrode
15, the second
electrode 16 and the second wire 13 are formed by a same conductive wire. The
first
electrode 15, the second electrode 16, and the second wire 13 may be once-sewn
by one
conductive wire, thereby improving the production efficiency.
[83] Of course, in other embodiments, it may also be that the first
electrode 15 is
located on the side where the first wire is located, and the second electrode
16 is located on
the side where the second wire 13 is located. The first electrode 15 and the
first wire are a
same conductive wire, so that the first electrode 15 and the first wire 12 are
sewn by one
conductive wire. The second electrode 16 and the second wire 13 are a same
conductive
wire, so that the second electrode 16 and the second wire 13 are sewn by one
conductive
wire.
[84] Further, the first electrode 15 and the second electrode 16 formed by
sewing may
be provided with a conductive layer 17, which can stabilize the resistance and
facilitate the
12
8610870
Date Recue/Date Received 2023-07-21
external connection of leads or contacts. In some embodiments, the conductive
layer 17 is
formed by coating or printing a conductive paste or a conductive adhesive.
[85] It can be understood that in other embodiments, the conductive layer
17 may also
be a metal sheet attached to the first electrode 15 and the second electrode
16. The material
of the metal sheet may be nickel, stainless steel, copper, aluminum foil, or
the like. Then
the metal sheet may be punctured and sewn to the first liquid conducting
member 11 by
sewing, so that the metal sheet and the first liquid conducting member 11 are
fixed and
compounded together. The advantage is that the electrode will have a certain
hardness,
making it more convenient to contact the external electrode of the atomizer.
[86] In addition, in some other embodiments, one or both of the first
electrode 15 and
the second electrode 16 are inserted into the first liquid conducting member
11. Preferably,
the heating assembly is clamped and fixed in a metal riveting method, and then
the atomizing
assembly is powered in a contact type by contacts or a lead-out type by lead
wires.
[87] Since the first liquid conducting member 11 is relatively fluffy and
needs to be
able to store more liquid, and meanwhile, the liquid leakage prevention effect
needs to be
good, a fluffy liquid conducting cotton is adopted. When the filamentous first
wire 12 and
second wire 13 of the heating assembly has a thinner wire diameter, such as a
wire diameter
of less than 0.08 mm, due to the liquid conducting cotton is fluffy, the
filamentous trajectory
for heating will be trapped in the liquid conducting cotton and thus will be
completely
wrapped by the liquid conducting cotton, as a result, the atomized vapor
cannot emerge from
the liquid conducting cotton, and a carbon deposition is easily formed on the
liquid
conducting cotton.
[88] Further, as shown in Fig. 14 and Fig. 15, in order to improve the
above problems,

first electrode 15 and the second electrode 16 to form the conductive layer
17, or, a metal
sheet is sewn onto the first electrode 15 and the second electrode 16 to form
the conductive
layer 17.
[102] As shown in Fig. 14 and Fig. 15, in some embodiments, support lines
18 are sewn
to the liquid conducting substrate before sewing the first wire 12, the second
wire 13, and the
electrode, and then the first wire 12, the second wire 13, and the electrode
are sewn on the
support lines 18 to avoid the first wire 12, the second wire 13, and the
electrode being
recessed.
[103] Combined with Fig. 13, when the size of the liquid conducting
substrate is small,
the liquid conducting substrate may be the first liquid conducting member 11.
Or, multiple
sets of heating assemblies and electrodes may be sewn on a large liquid
conducting substrate
in a zoned manner in advance. Preferably, the multiple sets of heating
assemblies and

manufacturing process of the atomizing assembly 10 in the first embodiment,
including the

[109] providing a flexible liquid conducting substrate;

[111] Specifically, the manufacturing process further includes the

providing a flexible second wire 13 which is made of an electrically
conductive material, and
interposing and sewing the second wire 13 on the liquid conducting substrate
to form the

[112] Further, the manufacturing process includes the following steps:

[113] Specifically, a conductive wire is sewn onto the liquid conducting
substrate to

[114] In some embodiments, the first electrode 15 and the second electrode

[116] Combined with Fig. 13, when the size of the liquid conducting
substrate is small,
the liquid conducting substrate may be the first liquid conducting member 11.
Or, multiple
sets of heating assemblies and electrodes may be sewn on a large liquid
conducting substrate
in a zoned manner in advance. Preferably, the multiple sets of heating
assemblies and
electrodes are sewn at one time, and the circuits in various zones are
connected. After the
sewing is completed, the liquid conducting substrate is cut to form a
plurality of atomizing
assemblies with heating assemblies and electrodes.
[117] Further, as shown in Fig. 16 to Fig. 18, in the third embodiment, the
heating
assembly includes a heating member 19 and a fixing thread 191. The fixing
thread 191 is
sewn to the liquid conducting substrate to fix the heating member 19. The
fixing thread 191
is sewn to fix the heating member 19 on the liquid conducting substrate,
making the heating
member 19 in a good contact with the liquid conducting substrate, enabling a
sufficient
atomization, meanwhile, facilitating the subsequent assembly, and making the
heating
member 19 less prone to deformation.
[118] The heating member 19 may be a flat-plate heating sheet with a
heating circuit
192 formed of a planar metal by cutting, stamping, etching, or the like.
Preferably, the
heating member 19 may be mesh shaped, and in other embodiments, the heating
member 19
may also be in a grid shape or a linear shape.
[119] In this embodiment, the heating member 19 includes two heating
circuits 192
arranged side by side, and several support portions 193 connected to the
heating circuits 192
respectively. The support portions 193 and the heating circuits 192 are
connected to each
other to form a mesh shaped heating member 19. The electrode is used for
connecting an
external lead or directly contacting an external electrode. The electrodes
include a first
electrode 15 and a second electrode 16 respectively connected to two ends of
the heating
circuits 192, for connecting to the power supply. The heating circuits 192
generate heat
after being energized.
[120] In this embodiment, the first electrode 15, the second electrode 16,
and the heating
member 19 are in an integrated structure and may be formed integrally. In
other
embodiments, the first electrode 15 and the second electrode 16 may also be
formed by
sewing the conductive wire/wires to the first liquid conducting member 11 and
electrically
connected to the heating member 19.
18
8610870
Date Recue/Date Received 2023-07-21
[121] In other embodiments, one or two sides of the heating circuits 192
are connected
with support portions 193. The heating circuits 192 are connected between the
electrodes,
and generate heat when the electrodes at the two ends are powered. The support
portions
play a role in connecting the multiple heating circuits 192, and making the
heating portion
have a certain strength.
[122] The fixing thread 191 used to fix the heating member 19 may be one
thread
interpenetrated between the liquid conducting cotton or two threads crossed
with each other,
and the fixing thread 191 needs to adopt a non-conductive filament or fiber.
The number of
the fixing threads 191 may be multiple or one.
[123] As the current travels the shortest distance in the circuit, and the
support portions
connected to the heating circuits 192 does not form a loop, the support
portions connected
between the two heating circuits 192 are in the loop but do not pass through
the current.
Therefore, when heating, the heat of the support portions is far lower than
that of the heating
portion, since the heat is mainly transmitted from the heating circuits 192.
Therefore, the
preferred sewing position of the fixing thread 191 is the position of the
support portion of the
heating member 19, since the temperature of the support portion of the heating
member 19 is
relatively low, and the temperature resistance requirement for the fixing
thread 191 for fixing
the heating member 19 is relatively low.
[124] The heating member 19 provides the following beneficial effects:
[125] 1, the heating member 19 can be produced by stamping to facilitate a
mass
production;
[126] 2, the spacing and the shape of the heating circuit 192 of the
heating member 19
are more regular, and the heat distribution is more stable, balanced, and
consistent.
[127] 3, the electrode portion can be designed to have a large area, which
is convenient
to connect with an external lead or contact with the electrode of the
atomizing device.
[128] Further, as shown in Fig. 19, when the heating member 19 is mesh
shaped, a
plurality of thinner conductive wires may be used to be woven into a mesh
shape, or a
conductive metal sheet or a conductive thin film may be used to be punched or
etched to form
a whole array of grids or mesh holes, to serve as a mesh-shaped heating
structure, and the
19
8610870
Date Recue/Date Received 2023-07-21
fixing thread 191 is sewn to the first liquid conducting member 11 to fix the
heating member
19. The heating member 19 is formed with a plurality of mesh holes penetrated
therethrough, and has a certain resistance value after being cut to a certain
size, and can be
used in the field of resistance heating.
[129] The heating member 19 may also be mesh shaped formed by weaving other
conductive fiber and non-conductive fiber, such as a cloth-like structure
formed by mixing
and weaving carbon fiber and cotton fiber. Wherein, the carbon fiber acts as
the conductive
wire, and generates heat after being electrified at the two ends to heat the
atomizable liquid.
The cotton fiber plays a role in conducting the liquid and is weave with the
carbon fiber to
provide a good fixing effect. The conductive wire is not limited to the carbon
fiber.
[130] The heating member 19 with the mesh structure formed by weaving is
commonly
used in a specification ranging from 50 meshes to 400 meshes (referring to the
number of
mesh holes per square inch). The mesh hole is small in size, and the liquid
can form a film
between the mesh holes due to liquid tension, so that the oil leakage is not
likely to happen.
Moreover, various parts of the heating member are in contact with the
conductive mesh, to
enable a large atomization area.
[131] The heating member 19 is relatively more uniform in heat, has a
larger heating
area, and tends to generate heat throughout the entire surface. The mesh-
shaped heating
member 19 generates heat more uniform and has a larger heating area. The mesh
spacing
and the heating trajectory of the heating member 19 are more regular, and the
heat
distribution is more stable, balanced, and consistent.
[132] Further, the present invention provides a manufacturing process of
the atomizing
assembly 10 in the third embodiment, including the following steps:
[133] providing a flexible liquid conducting substrate;
[134] sewing a heating assembly on the liquid conducting substrate.
[135] Specifically, in this embodiment, manufacturing process further
includes the
following steps: providing a heating member 19 and a fixing thread 191, and
sewing the
fixing thread 191 onto the liquid conducting substrate to fix the heating
member 19.

[136] In this embodiment, the electrode and the heating member 19 are in an
integrated
structure. In other embodiments, referring to the first embodiment and the
second
embodiment, the electrode is arranged on the liquid conducting substrate by
such as sewing,
and a conductive layer 17 is arranged on the electrode to electrically connect
the electrode
and the heating member 19.
[137] When the size of the liquid conducting substrate is small, the liquid
conducting
substrate may be the first liquid conducting member 11. Or, multiple sets of
heating
assemblies and electrodes may be sewn on a large liquid conducting substrate
in a zoned
manner in advance. Preferably, the multiple sets of heating assemblies and
electrodes are
sewn at one time, and the circuits in various zones are connected. After the
sewing is
completed, the liquid conducting substrate is cut to form a plurality of
atomizing assemblies
with heating assemblies and electrodes.
[138] The above heating assembly of the atomizing assembly 10 can be
manufactured to
the first liquid conducting member 11 in a sewing manner, and the structure of
the atomizing
assembly 10 has the following advantages: the production is relatively simple
and easy to
implement, the heating material is fixed on the liquid conducting substrate
based on the
sewing principle, to form the atomizing assembly with good reliability, easy
to batch
production, and having good contact between the heating and the liquid
conducting substrate,
and the problems that the flexible liquid conducting substrate such as the
liquid conducting
cotton, is prone to being in poor contact with the heating assembly during
application to
result in dry burning, the heating assembly is prone to deformation, and
taking is difficult
during assembly, are solved.
[139] It is understood that the above-mentioned technical features can be
used in any
combination without limitation.
[140] While the present invention has been illustrated and described in
detail in the
drawings and foregoing description, such illustration and description are to

changes and
modifications may be made by those of ordinary skill within the scope of the
following
