Description

Technical Field

[0001] The present invention relates to the technical field of electronic atomization devices, and in particular to an atomization core, an atomizer, and an electronic atomization device. Background Art

[0002] The atomizing core is a device used to heat and atomize the aerosol-generating substrate when powered on to form an aerosol that can be consumed by the user.

[0003] At present, the atomizer core generally includes liquid-conducting cotton and a heating element; the liquid-conducting surface is used to guide the aerosol-generating matrix; the heating element is used to heat and atomize the aerosol-generating matrix to form an aerosol when powered on.

[0004] However, slight changes in the tightness of the liquid-guiding cotton can significantly affect its liquid-guiding rate. If the liquid-guiding cotton's liquid-guiding rate is too low, the atomizer core is prone to insufficient oil supply during atomization, shortening the life of the heater. On the other hand, if the liquid-guiding cotton's liquid-guiding rate is too high, the atomizer core is prone to leakage during atomization, seriously affecting the user's vaping experience. Therefore, it is difficult to find a balance between the tightness of the liquid-guiding cotton and the heater core during adjustment. Summary of the Invention

[0049] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0050] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of an electronic atomization device 100 provided in one embodiment of the present application. In this embodiment, an electronic atomization device 100 is provided, which can be used to atomize an aerosol-generating substrate to form an aerosol for user inhalation. The aerosol-generating substrate can be a plant leaf substrate or a paste-like substrate. Specifically, the electronic atomization device 100 includes an atomizer 101 and a power supply assembly 102.

[0051] The nebulizer 101 can be used in various fields, such as medical atomization and electronic atomization.

The atomizer 101 and the power supply assembly 102 may be detachably connected to facilitate replacement of the atomizer 101 and improve the utilization of the power supply assembly 102. Of course, in other embodiments, the power supply assembly 102 and the atomizer 101 may also be integrally provided, and this application is not limited thereto.

[0053] Please refer to Figure 2 , Figure 2 Schematic diagram of the structure of an atomizer 101 provided in one embodiment of the present application. In this embodiment, an atomizer 101 is provided, which includes a housing 10 and an atomizer core 20. Furthermore, the atomizer 101 may also include a mounting seat and a sealing member.

[0054] The housing 10 has a receiving cavity, within which the atomizer core 20 is disposed. The atomizer core 20 cooperates with the inner wall of the housing 10 to form a liquid storage cavity 30 for storing an aerosol-generating substrate. In a specific embodiment, the atomizer core 20 is configured to heat and atomize the aerosol-generating substrate from the liquid storage cavity 30 to form an aerosol when powered.

[0055] The atomizer core 20 may be any of the following embodiments. For its specific structure and function, please refer to the following description of the atomizer core 20 , and the same or similar technical effects can be achieved.

[0056] See also Figures 3 to 8 ,in, Figure 3 A schematic structural diagram of the atomizer core 20 provided in one embodiment of the present application; Figure 4a for Figure 3 A cross-sectional view of the atomizer core 20 taken along the AA direction is shown; Figure 4b for Figure 4a Disassembly diagram of the Figure 5 for Figure 3 A cross-sectional view of the atomizer core 20 taken along the BB direction is shown;

[0057] Figure 6 This is a schematic diagram of the structure of the atomizer core 20 provided in one embodiment of the present application, excluding the liquid inlet pipe 23 and the heating seat 24; Figure 7A schematic structural diagram of the first liquid-guiding member 21 with a five-layer structure provided in the first embodiment of the present application after unfolding; Figure 8 for Figure 7 Schematic diagram of the disassembly.

[0058] In this embodiment, if Figures 3 to 6 As shown, an atomizer core 20 is provided. The atomizer core 20 includes a first liquid guide member 21 and a heating member 22. The first liquid guide member 21 is layered and can be arranged in a ring shape, that is, forming a hollow column.

[0059] Specifically, such as Figure 7 and Figure 8 As shown, the first liquid guiding member 21 may include at least one liquid guiding layer; and the first liquid guiding member 21 has a first side and a second side arranged opposite to each other; wherein, the first side of the first liquid guiding member 21 specifically refers to the outermost side of the annular first liquid guiding member 21, and the second side of the first liquid guiding member 21 specifically refers to the innermost side of the annular first liquid guiding member 21. In a specific embodiment, the first liquid guiding member 21 is specifically used to guide the aerosol generating matrix from the first side to the second side. wherein, the first liquid guiding member 21 may be liquid guiding cotton, so as to guide the aerosol generating matrix from the first side to the second side through the capillary force of the liquid guiding cotton. Specifically, the liquid guiding cotton may be linen, so as to ensure the temperature resistance and environmental protection of the first liquid guiding member 21; of course, the liquid guiding cotton may also be non-woven fabric.

[0060] In a specific embodiment, if Figure 8 As shown, the first liquid guiding member 21 includes multiple liquid guiding layers (not shown), and at least one of the multiple liquid guiding layers is provided with a first liquid guiding hole 211, so that the first liquid guiding member 21 can specifically guide the aerosol-generating substrate from the first side to the second side through the first liquid guiding hole 211. The first liquid guiding member 21 guides the aerosol-generating substrate through the first liquid guiding hole 211, thereby reducing the flow resistance and improving the flow guiding capacity. Furthermore, compared to a solution that only guides the flow through the capillary force of the liquid guiding cotton, the oil supply rate of the first liquid guiding member 21 is mainly determined by the relevant performance parameters of the first liquid guiding hole 211. For example, the liquid supply rate of the first liquid guiding member 21 can be increased by increasing the width and / or number of the first liquid guiding holes 211, or reduced by reducing the width and / or number of the first liquid guiding holes 211. Therefore, the oil supply rate of the first liquid guiding member 21 is less affected by the tightness of the first liquid guiding member 21. At the same time, in a specific embodiment, the first liquid guide holes 211 with corresponding parameters such as number or width can be set according to the actual required flow rate, so as to ensure that the atomizer core 20 can avoid the problem of insufficient oil supply due to a low oil supply rate, and can also avoid the problem of suction leakage due to a fast oil supply rate.

[0061] Among them, the shape of the first liquid guide hole 211 is not limited, and can be circular, elongated or elliptical, etc. Among them, the elongated shape can be runway-shaped or rectangular, etc. The angle value of the angle between the length direction of the elongated first liquid guide hole 211 and the length direction of the first liquid guide member 21 after it is unfolded (i.e., the inclination angle value α) can be 0°-180°. Preferably, the angle value of the angle between the length direction of the elongated first liquid guide hole 211 and the length direction of the first liquid guide member 21 after it is unfolded can be 0°, 45° or 90°, so as to facilitate the radial, circumferential and / or axial diffusion of the aerosol-generating matrix along the first liquid guide member 21, thereby improving the uniformity of liquid conduction.

[0062] The width of the first liquid guiding hole 211 may be 1.0 mm to 5 mm, so as to utilize the capillary force of the first liquid guiding hole 211 to guide the flow while avoiding the problem of excessively fast liquid guiding rate and leakage caused by a larger width.

[0063] The heating element 22 is disposed on the second side of the first liquid-guiding member 21 and is used to heat and atomize the aerosol-generating substrate when powered. Specifically, the heating element 22 is disposed on the surface of the second side of the first liquid-guiding member 21, that is, the heating element 22 is disposed on the innermost surface of the first liquid-guiding member 21, to heat and atomize the aerosol-generating substrate directed to the innermost surface of the first liquid-guiding member 21. The heating element 22 can be a heating film or a metal frame, such as a copper mesh.

[0064] The atomizer core 20 provided in this embodiment is provided with a first liquid guide member 21 and a first liquid guide hole 211 is opened on the first liquid guide member 21 to guide the aerosol-generating substrate from the first side of the first liquid guide member 21 to the second side through the first liquid guide hole 211. This not only prevents the tightness of the first liquid guide member 21 from affecting the liquid guide rate of the atomizer core 20, but also ensures that the atomizer core 20 is not only adequately supplied with oil during the atomization process, but also does not suffer from suction leakage problems by controlling the number and width of the first liquid guide holes 211, thereby effectively extending the service life of the heating element 22. In addition, by providing the heating element 22, the heating element 22 is arranged on the second side of the first liquid guide member 21, so that when the heating element 22 is energized, the heating element 22 heats and atomizes the aerosol-generating substrate to form an aerosol.

[0065] In this embodiment, if Figure 8As shown, the first liquid-conducting member 21 specifically comprises a stack of multiple non-porous liquid-conducting layers 21a and multiple porous liquid-conducting layers 21b. First liquid-conducting holes 211 are specifically defined in the porous liquid-conducting layers 21b; each porous liquid-conducting layer 21b may include multiple, spaced-apart first liquid-conducting holes 211 to improve the uniformity of the aerosol-generating matrix on the first liquid-conducting member 21. Specifically, the multiple first liquid-conducting holes 211 on different porous liquid-conducting layers 21b may be arranged in a one-to-one correspondence, as will be used in the following embodiments. Of course, staggered or irregularly distributed arrangements are also possible, and this is not a limitation of the present application. In this embodiment, by making the first liquid-conducting member 21 include a non-porous liquid-conducting layer 21a and a porous liquid-conducting layer 21b, not only can the first liquid-conducting holes 211 on the porous liquid-conducting layer 21b be used to conduct liquid to the aerosol-generating substrate, but the non-porous liquid-conducting layer 21a can also be used to avoid the problem of a fast oil supply rate in the first liquid-conducting holes 211 and leakage. Therefore, by adjusting the number and layout of the non-porous liquid-conducting layer 21a and the porous liquid-conducting layer 21b, the diffusion rate of the aerosol-generating substrate in the first liquid-conducting member 21 can be effectively controlled.

[0066] Figure 8 In the embodiment, the first liquid-conducting member 21 has a five-layer structure, including three non-porous liquid-conducting layers 21a and two porous liquid-conducting layers 21b. The two porous liquid-conducting layers 21b are both non-woven fabrics. The three non-porous liquid-conducting layers 21a include two layers of linen and one layer of non-woven fabric. The non-woven fabric serving as the non-porous liquid-conducting layers 21a is sandwiched between the two layers of linen and the two layers of porous liquid-conducting layers 21b.

[0067] In a specific embodiment, if Figure 8 As shown, all non-porous liquid-conducting layers 21a are arranged on the same side of all porous liquid-conducting layers 21b. Figure 9 , Figure 9 This is a schematic diagram of a disassembled six-layer first liquid-conducting member 21 provided in the second embodiment of the present application. Non-porous liquid-conducting layers 21a and porous liquid-conducting layers 21b are arranged alternately. In this embodiment, one, two, or three non-porous liquid-conducting layers 21a may be arranged between two adjacent porous liquid-conducting layers 21b; alternatively, one, two, or three porous liquid-conducting layers 21b may be arranged between two adjacent non-porous liquid-conducting layers 21a, although this application does not limit this. Figure 9 In the embodiment, from the outermost layer to the innermost layer, the first and third layers are porous liquid-conducting layers 21b, and the other layers are non-porous liquid-conducting layers 21a; the first, second and fourth layers are non-woven fabrics, and the other layers are linen.

[0068] In a specific embodiment, the heating element 22 is in contact with the non-porous liquid-conducting layer 21a of the first liquid-conducting element 21. That is, at least one liquid-conducting layer of the first liquid-conducting element 21 that contacts the heating element 22 is a non-porous liquid-conducting layer 21a. This increases the effective contact area between the heating element 22 and the first liquid-conducting element 21 and improves atomization uniformity. In a specific embodiment, several adjacent liquid-conducting layers disposed immediately adjacent to the heating element 22 may be non-porous liquid-conducting layers 21a to prevent excessively rapid oil supply.

[0069] Furthermore, in the first liquid-guiding member 21 , except for the liquid-guiding layer in contact with the heating element 22 , at least the outermost liquid-guiding layer along the direction from the second side to the first side is a porous liquid-guiding layer 21 b to reduce the oil supply resistance and increase the oil supply rate.

[0070] Among them, see Figures 10a to 10e ,in, Figure 10a A schematic structural diagram of the porous liquid-conducting layer 21b provided in the first embodiment of the present application; Figure 10b A schematic structural diagram of a porous liquid-conducting layer 21b provided in the second embodiment of the present application; Figure 10c A schematic structural diagram of a porous liquid-conducting layer 21b provided in the third embodiment of the present application; Figure 10d A schematic structural diagram of a porous liquid-conducting layer 21b provided in a fourth embodiment of the present application; Figure 10e This is a schematic structural diagram of the porous liquid-conducting layer 21b provided in the fifth embodiment of the present application.

[0071] In one embodiment, if Figure 10a As shown, the first liquid-conducting holes 211 on the same porous liquid-conducting layer 21b have different shapes, and the first liquid-conducting holes 211 of different shapes are alternately distributed along the circumference of the porous liquid-conducting layer 21b to regulate the liquid-conducting rate of the entire first liquid-conducting member 21. Specifically, the same porous liquid-conducting layer 21b may include vertically arranged elongated first liquid-conducting holes 211 and circular first liquid-conducting holes 211, which are alternately distributed and evenly spaced to guide liquid to the aerosol-generating substrate in the axial and radial directions.

[0072] In another embodiment, Figures 10b to 10e As shown, the shapes of the multiple first liquid conducting holes 211 on the same porous liquid conducting layer 21b are the same, for example, all are in the shape of a racetrack (see Figure 10b 、 Figure 10c or Figure 10d ) or round (see Figure 10e ), and the plurality of first liquid conducting holes 211 can be arranged at equal intervals along the circumferential direction of the porous liquid conducting layer 21b.

[0073] In one embodiment, the shapes of the multiple first liquid-conducting holes 211 on the same porous liquid-conducting layer 21b are the same, while the shapes of the first liquid-conducting holes 211 on different porous liquid-conducting layers 21b are different, so as to regulate the overall liquid-conducting rate and diffusion range of the first liquid-conducting layer. For example, the first liquid-conducting holes 211 on one of two adjacent porous liquid-conducting layers 21b are elongated, while the first liquid-conducting holes 211 on the other porous liquid-conducting layer 21b are circular; or, as follows Figure 11-12 As shown, the first liquid conducting holes 211 on one layer of the porous liquid conducting layer 21b are long strips with an inclination angle α of 45°, and the first liquid conducting holes 211 on the other layer of the porous liquid conducting layer 21b are long strips with an inclination angle α of 135°, so as to increase the lateral diffusion range of the aerosol generating matrix.

[0074] In another specific embodiment, the first liquid guiding holes 211 on the same porous liquid guiding layer 21b have the same shape, while the first liquid guiding holes 211 on different porous liquid guiding layers 21b have the same shape but are arranged differently. For example, the first liquid guiding holes 211 on both porous liquid guiding layers 21b may be elongated or circular, but the first liquid guiding holes 211 on one porous liquid guiding layer 21b are evenly spaced along the circumference of the porous liquid guiding layer 21b, while the first liquid guiding holes 211 on the other porous liquid guiding layer 21b are evenly distributed throughout the porous liquid guiding layer 21b.

[0075] In another specific embodiment, Figure 8 As shown, the first liquid-conducting holes 211 on the same porous liquid-conducting layer 21b have the same shape, and the first liquid-conducting holes 211 on different porous liquid-conducting layers 21b have the same shape and are arranged in the same manner. Specifically, the first liquid-conducting holes 211 on two adjacent liquid-conducting layers also have the same shape and are arranged in a one-to-one correspondence to improve liquid-conducting efficiency. In this embodiment, the first liquid-conducting holes 211 may be in the shape of a racetrack extending along the width of the liquid-conducting layer.

[0076] See also Figure 11 as well as Figure 16 ,in, Figure 11 A schematic structural diagram of a first liquid-guiding member 21 with a six-layer structure provided in the third embodiment of the present application; Figure 12 for Figure 11 Disassembly diagram of the

[0077] Figure 13 A disassembled schematic diagram of the first liquid-guiding member 21 with a six-layer structure provided in the fourth embodiment of the present application; Figure 14 A schematic structural diagram of a first liquid-guiding member 21 provided in a fifth embodiment of the present application; Figure 15 for Figure 14 Disassembly diagram of the Figure 16This is a disassembled schematic diagram of the six-layer first liquid guiding member 21 provided in the sixth embodiment of the present application. The first liquid guiding holes 211 on each porous liquid guiding layer 21b are all in the shape of an elongated strip.

[0078] In a specific embodiment, if Figures 11 to 13 As shown, the projections of the first liquid-conducting holes 211 on two adjacent porous liquid-conducting layers 21b in the thickness direction of the porous liquid-conducting layers 21b intersect at an angle of 30°-90°, thereby directing liquid to the aerosol-generating substrate in different directions. Specifically, the sum of the inclination angle α of the first liquid-conducting holes 211 on one of the two adjacent porous liquid-conducting layers 21b and the inclination angle α of the first liquid-conducting holes 211 at corresponding positions on the other porous liquid-conducting layer 21b can be 180 degrees. Preferably, the corresponding first liquid-conducting holes 211 on the two adjacent porous liquid-conducting layers 21b are projected to intersect at an angle of 90°. For example, if the inclination angle α of the first liquid conducting holes 211 on one of the two adjacent porous liquid conducting layers 21b is 45°, then the inclination angle α of the first liquid conducting holes 211 at the corresponding position on the other porous liquid conducting layer 21b is 135°, so as to facilitate the diffusion of the aerosol generating matrix along the circumferential and axial directions of the first liquid conducting member 21.

[0079] In another specific embodiment, Figures 14 to 16 As shown, the first liquid-conducting holes 211 on two adjacent porous liquid-conducting layers 21b are staggered, and the projections of the first liquid-conducting holes 211 on the two adjacent porous liquid-conducting layers 21b in the thickness direction of the porous liquid-conducting layers 21b are connected end to end, so that the first liquid-conducting holes 211 are connected to each other, thereby improving the liquid-conducting rate and uniformity. In this embodiment, the inclination angle α of each first liquid-conducting hole 211 is greater than 0°. Preferably, if the inclination angle α of the first liquid-conducting holes 211 on one of the two adjacent porous liquid-conducting layers 21b is 45°, the inclination angle α of the first liquid-conducting holes 211 at the corresponding position on the other porous liquid-conducting layer 21b is 135°.

[0080] Of course, in other embodiments, the shapes of the multiple first liquid-conducting holes 211 on the same porous liquid-conducting layer 21b may be partially identical, partially different, or completely different. The shapes and positions of the first liquid-conducting holes 211 on different liquid-conducting layers may also be selected based on actual needs. For example, the projections of the first liquid-conducting holes 211 in the thickness direction of the porous liquid-conducting layer 21b may partially overlap or not overlap. This application does not impose any restrictions on this, as long as sufficient liquid supply is ensured and leakage is prevented.

[0081] In one embodiment, see Figures 3 to 6 The atomizer core 20 further includes a liquid inlet pipe 23 , a heating seat 24 and a second liquid guide member 25 .

[0082] The liquid inlet tube 23 has a tubular structure, and at least one liquid inlet hole 231 is defined on the sidewall of the liquid inlet tube 23. The aerosol-generating substrate enters the first side of the first liquid-guiding member 21 through the liquid inlet hole 231. In one embodiment, the sidewall of the liquid inlet tube 23 has multiple liquid inlet holes 231 defined thereon. The multiple liquid inlet holes 231 may be evenly spaced along the circumference of the liquid inlet tube 23. Specifically, the liquid inlet holes 231 may extend along the axial direction of the liquid inlet tube 23.

[0083] At least part of the heating seat 24 is sleeved in the liquid inlet pipe 23 to achieve connection with the liquid inlet pipe 23. Specifically, the heating seat 24 is interference fit with the liquid inlet pipe 23. Among them, the heating seat 24 is hollow. In a specific embodiment, the first liquid guide member 21 is specifically arranged in an annular shape on the inner surface of the heating seat 24, and is surrounded to form an atomization chamber. Specifically, the side wall of the heating seat 24 is also provided with a guide hole 241 at the position corresponding to the liquid inlet hole 231, so that the aerosol generating matrix can pass through. Specifically, the guide hole 241 can correspond one-to-one with the position of the liquid inlet hole 231; further, the guide hole 241 can be consistent with the size and / or shape of the liquid inlet hole 231 to reduce the diversion resistance.

[0084] In one embodiment, the portion of the heating base 24 embedded within the liquid inlet tube 23 is spaced from the inner sidewall of the liquid inlet tube 23 to form a ventilation channel. A second liquid guide 25 is specifically disposed between the heating base 24 and the liquid inlet tube 23 and embedded within the ventilation channel. This allows ventilation of the liquid storage chamber 30 through the second liquid guide 25, thereby maintaining air pressure balance inside and outside the liquid storage chamber 30 to ensure that the aerosol-generating substrate can flow smoothly out of the liquid storage chamber 30. The second liquid guide 25 can also be a liquid-guiding cotton; the liquid-guiding cotton can be made of non-woven fabric.

[0085] In a specific embodiment, Figure 4b As shown, to minimize the impact of the second liquid guide 25 on the flow rate of the atomizer core 20 and ensure the liquid supply rate without affecting the ventilation of the second liquid guide 25, a plurality of second liquid guide holes 251 can be provided in the second liquid guide 25. This allows the aerosol-generating substrate entering the liquid inlet 231 to be directed through the second liquid guide holes 251 to the first liquid guide 21. It will be appreciated that in this embodiment, the aerosol-generating substrate within the liquid storage chamber 30 is sequentially directed through the liquid inlet 231, the second liquid guide holes 251, and the flow guide holes 241 to the first side of the first liquid guide 21, and then through the first liquid guide holes 211 to the innermost surface of the first liquid guide 21, where it is heated and atomized by the heating element 22 disposed on this innermost surface to form an aerosol. In specific embodiments, the first liquid guide holes 211 and / or the second liquid guide holes 251 can be through holes.

[0086] Specifically, the second liquid guiding member 25 can be a single liquid guiding layer, and the second liquid guiding member 25 can specifically be liquid guiding cotton. Of course, in other specific embodiments, the second liquid guiding member 25 can also be a liquid guiding layer arranged in multiple layers, and this application is not limited to this. Among them, the shape and distribution of the second liquid guiding holes 251 on the second liquid guiding member 25 and the distribution of the first liquid guiding holes 211 on different layers of liquid guiding layers can be the same or similar to the shape and distribution of the first liquid guiding holes 211 on the above-mentioned first liquid guiding member 21, and can achieve the same or similar technical effects, which will not be repeated here.

[0087] Further, see Figure 17 and Figure 18 , Figure 17 A schematic structural diagram of a gap provided on the first liquid guiding member 21 or the second liquid guiding member 25 according to an embodiment of the present application; Figure 18 This is a schematic diagram of another embodiment of the present application, showing a structure in which slits are provided in the first liquid-guiding member 21 or the second liquid-guiding member 25. In one embodiment, the first liquid-guiding member 21 and / or the second liquid-guiding member 25 further have multiple slits 212, which facilitate the flow of aerosol-generating substrate along and through the slits 212. This reduces stress on the first liquid-guiding member 21 and / or the second liquid-guiding member 25, facilitating installation. The width of the slits 212 ranges from 0.1 mm to 2 mm.

[0088] In a specific embodiment, if Figure 17 As shown, each slit 212 may extend along the circumferential direction of the first liquid guiding member 21 or the second liquid guiding member 25 , and a plurality of slits 212 may be arranged at equal intervals along the width direction of the first liquid guiding member 21 or the second liquid guiding member 25 .

[0089] In another specific embodiment, Figure 18 As shown, the angle between the length direction of each slit 212 and the length direction of the first liquid guiding member 21 and / or the second liquid guiding member 25 after unfolding is greater than 0° and less than or equal to 90°; and multiple slits 212 can be arranged at equal intervals along the circumferential direction of the slit 212.

[0090] For details, see Figure 19 , Figure 19 A structural schematic diagram of another embodiment of the present application provides a gap on the first liquid guiding member 21 or the second liquid guiding member 25; when the first liquid guiding layer 21 and / or the second liquid guiding layer 25 have both liquid guiding holes and gaps 212, the gaps 212 can connect adjacent liquid guiding holes, thereby further increasing the circumferential liquid guiding effect of the liquid guiding member.

[0091] In a specific embodiment, the atomizer core 20 may further include a seal and an ejector pin. The seal is disposed at the bottom of the base and is used to seal the atomization chamber to prevent leakage of the aerosol-generating substrate within the atomization chamber and short circuiting of the leads of the heating element 22. Specifically, the seal may be made of sealing silicone.

[0092] The ejector pin is connected to the heating element 22, and the ejector pin is used to connect to the power supply assembly 102 to connect the heating element 22 with the power supply assembly 102, so that the power supply assembly 102 supplies power to the heating element 22. In a specific embodiment, an air inlet and two mounting holes are provided on the heating seat 24; wherein, the atomizing chamber is connected to the outside atmosphere through the air inlet to form an airflow during the user's inhalation process. The ejector pin is inserted into the mounting hole to connect with the heating element 22 in the atomizing chamber. Specifically, the ejector pin may include a positive electrode ejector pin and a negative electrode ejector pin, and the positive electrode ejector pin and the negative electrode ejector pin are arranged in a one-to-one correspondence with the two mounting holes.

[0093] The above is only an implementation method of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
