[0034] The realization of the objectives, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0036] Existing aerosol generating devices mainly include a main unit and an atomizer. The atomizer is detachably mounted on the main unit, and an atomizer core is installed in the atomizer. The atomizer core is used to atomize the aerosol-generating liquid into an aerosol. However, as the atomizer is used for a long time, the performance of the atomizer core will decline, thereby affecting the quality of aerosol generation. The atomizer core in the existing atomizer is not convenient for users to remove and replace by themselves. Users can only replace the entire atomizer, which results in high usage costs.

[0037] Therefore, the atomizer of the present application is provided with an electrode seat, which is an electrical conductor. The electrode seat not only serves to electrically connect the second atomizing electrode on the atomizing core with the second host electrode on the host, but also serves to limit the atomizing core. The electrode seat is also detachably connected to the shell. Therefore, when the atomizing core needs to be replaced, it is only necessary to remove the electrode seat from the shell to remove the atomizing core. After replacing the atomizing core, the atomizing core can be re-limited in the installation groove of the shell by the electrode seat. No complicated operations are required during the disassembly and reassembly process, which is very convenient and quick, thereby reducing the cost of use.

[0038] The atomizer provided in the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0039] First, if Figure 7 As shown, the atomizer 100 proposed in this application is used to connect to the host 200 in the aerosol generating device 300. The host 200 is provided with a first host electrode 210 and a second host electrode 220. One of the first host electrode 210 and the second host electrode 220 is a positive electrode and the other is a negative electrode. The first host electrode 210 and the second host electrode 220 both have one end extending out of the host 200 and the other end electrically connected to a circuit board (not shown) disposed within the host 200. The host 200 is generally also provided with a detection module (also called a microphone) for detecting whether the user has inhaled, a battery for providing electrical energy, a charging plate for controlling charging, etc. The specific structure of the host 200 can be designed according to relevant existing technologies and is not specifically limited here.

[0040] like Figure 1 As shown, the atomizer 100 proposed in this application mainly includes a housing 10 and an atomizing assembly 20 .

[0041] Among them, Figure 5 As shown, Figure 5 This is a structural cross-sectional view of an embodiment of the shell 10. A first air duct 11, a mounting groove 12 and a liquid storage tank 151 are provided in the shell 10. One end of the first air duct 11 forms a suction nozzle opening 111, and the other end is connected to the bottom 121 of the mounting groove 12. The mounting groove 12 has a groove opening 122 opposite to the bottom 121. The liquid storage tank 151 is arranged around the first air duct 11, and the liquid storage tank 151 is provided with a liquid outlet (not shown) on the bottom 121.

[0042] Specifically, the housing 10 is assembled from a plurality of parts, or can be integrally formed, for example, Figure 3 In the embodiment shown, the housing 10 includes a main housing 13, a sub-housing 14 and a liquid cup 15. The interior of the main housing 13 is hollow to form a mounting cavity. The upper end of the main housing 13 (with Figure 3 The orientation is indicated in the figure for reference) and a nozzle 131 is provided on the protruding end, and a mounting opening is provided on the lower end. Figure 5 It is understood that a liquid storage tank 151 is provided in the liquid cup 15, and the liquid storage tank 151 is used to store the aerosol generating liquid 30, and a part of the liquid cup 15 is installed in the installation cavity of the main shell 13 through the installation opening, and the other part extends out of the main shell 13, and the auxiliary shell 14 is sleeved on the part of the liquid cup 15 extending out of the main shell 13, and the auxiliary shell 14 is snap-connected to the main shell 13.

[0043] The liquid cup 15 is further provided with an injection hole 152 at a position corresponding to the secondary housing 14. This injection hole 152 is used to inject the aerosol-generating liquid 30 into the liquid reservoir 151, thereby facilitating the user to add aerosol-generating liquid 30 as needed. A plug 141 is provided on the secondary housing 14 at a position corresponding to the injection hole 152. This plug 141 is used to seal the injection hole 152 to prevent the aerosol-generating liquid 30 from flowing out of the injection hole 152.

[0044] It should be noted that any two of the main shell 13, the auxiliary shell 14, and the liquid cup 15 can be integrally formed, or the main shell 13, the auxiliary shell 14, and the liquid cup 15 can be integrally formed. In addition, the housing 10 may also include other accessories, such as a nozzle cover 16 that fits over the nozzle 131, or a decorative piece 17 that is assembled on the main shell 13 to enhance the appearance of the atomizer 100.

[0045] like Figure 5 As shown, the housing 10 further includes a first air channel 11 and a mounting groove 12. The mounting groove 12 is located at the lower end of the housing 10 and has a bottom 121 and a notch 122 that face each other. When the aerosol generating device 300 is assembled, the notch 122 faces the main unit 200. The first air channel 11 extends in a straight line, with the upper end of the first air channel 11 forming a nozzle opening 111. The lower end of the first air channel 11 extends through the bottom 121 of the mounting groove 12, thereby communicating with the mounting groove 12. The first air channel 11 is used to supply aerosol to the nozzle opening 111.

[0046] The liquid storage tank 151 is an annular cylindrical cavity. The liquid storage tank 151 is located above the mounting groove 12 and is arranged around the first air channel 11. The liquid storage tank 151 has a liquid outlet formed on the groove bottom 121 of the mounting groove 12. The liquid outlet is used to allow the aerosol generating liquid 30 in the liquid storage tank 151 to flow out of the liquid storage tank 151, so that the aerosol generating liquid 30 can flow to the atomization core 21 and be atomized.

[0047] like Figure 1 or Figure 6 As shown, the atomizer assembly 20 includes an atomizer core 21 and an electrode holder 22, wherein the atomizer core 21 is a porous body, specifically cotton, non-woven fabric, glass fiber, porous ceramic material, porous metal material, etc. Figure 4 As shown, the atomizer core 21 is arranged in the mounting groove 12 and can be combined with Figure 6 It is understood that the atomizer core 21 has a block structure and has a relative liquid absorption surface 211 and an atomization surface 212. The liquid absorption surface 211 is arranged opposite to the liquid outlet. When the aerosol generating liquid 30 flows out of the liquid storage tank 151 from the liquid outlet, the aerosol generating liquid 30 can flow onto the atomizer core 21.

[0048] like Figure 2As shown, a heating element 23 is provided on the atomizing surface 212. The heating element 23 can be a metal wire or a metal sheet, and the heating element 23 includes a first atomizing electrode 231 and a second atomizing electrode 232 connected to each other. The first atomizing electrode 231 is used to electrically connect to the first host electrode 210 on the host 200, and the second atomizing electrode 232 is used to electrically connect to the second host electrode 220 on the host 200. In this way, the heating element 23 can form a conductive loop with the circuit on the host 200. After power is turned on, the heat generated can convert electrical energy into thermal energy, thereby atomizing the aerosol generating liquid 30 on the atomizing core 21 into aerosol.

[0049] In order to allow the aerosol generated by atomization on the atomization surface 212 to flow into the first airway 11, as shown in FIG. Figure 4 As shown, the atomizer core 21 is further provided with a second air channel 213 extending from the liquid suction surface 211 to the atomizing surface 212. The second air channel 213 is respectively connected to the first air channel 11 and the notch 122. When the user inhales through the mouthpiece 131, air flows in from the notch 122 of the mounting groove 12. The air mixes with the aerosol particles at the atomizing surface 212 to form an aerosol. The aerosol then passes through the second air channel 213 and the first air channel 11 in sequence, and finally flows to the mouthpiece opening 111 and out through the mouthpiece opening 111.

[0050] like Figure 1 and Figure 2 As shown, the electrode holder 22 is detachably mounted in the mounting groove 12 , and the electrode holder 22 is configured to limit the movement of the atomizer core 21 in a direction away from the first air channel 11 , the electrode holder 22 is electrically connected to the second atomizer electrode 232 , and the electrode holder 22 is used to be electrically connected to the second host electrode 220 .

[0051] Specifically, in this embodiment, the electrode holder 22 is a conductor, and the material of the electrode holder 22 can be copper, aluminum, copper alloy, aluminum alloy, etc. When the electrode holder 22 is installed in the installation groove 12, the electrode holder 22 can block part of the end surface of the atomizer core 21 to limit the atomizer core 21 from downwardly separating from the housing 10. Figure 7 The electrode holder 22 is electrically connected to the second atomizing electrode 232 on the atomizing core 21. When assembling the aerosol generating device, the electrode holder 22 is electrically connected to the second host electrode 220 on the host 200. In this way, the electrical connection between the second atomizing electrode 232 and the second host electrode 220 can be achieved through the electrode holder 22, so that the heating element 23 can form a conductive loop with the circuit on the host 200.

[0052] In order to make the electrode holder 22 removable, there can be multiple ways to install the electrode holder 22 in the mounting groove 12. For example, the electrode holder 22 can be detachably installed in the mounting groove 12 by threaded connection, snap connection, magnetic connection, connecting parts (such as screws, airway parts 24), etc. Therefore, the specific installation method of the electrode holder 22 in the mounting groove can be flexibly selected according to actual needs, as long as the electrode holder 22 can be stably installed in the mounting groove 12 and can be easily disassembled.

[0053] In summary, it can be understood that the atomizer 100 of the present application is provided with an electrode holder 22, which is an electrical conductor. The electrode holder 22 not only serves to electrically connect the second atomizing electrode 232 on the atomizing core 21 with the second host electrode 220 on the host 200, but also serves to limit the atomizing core 21 and prevent the atomizing core 21 from detaching. In addition, the electrode holder 22 is also detachably connected to the shell 10. Therefore, when the atomizing core 21 needs to be replaced, it is only necessary to remove the electrode holder 22 from the shell 10 to remove the atomizing core 21. After replacing the new atomizing core 21, the atomizing core 21 can be re-limited in the mounting groove 12 of the shell 10 by the electrode holder 22. No complicated operations are required during the disassembly and reassembly process, which is very convenient and quick.

[0054] It should be noted that, in order to facilitate the removal of the atomizer core 21, the atomizer core 21 can be detachably connected to the inner wall of the mounting groove 12, or detachably connected to the electrode holder 22. For example, in one embodiment, Figure 6 As shown, the electrode holder 22 is provided with a limiting cavity 221. Figure 4 As shown, when the electrode holder 22 is installed in the mounting groove 12, the limiting cavity 221 is communicated with the first airway 11 and the notch 122 respectively, and the atomizer core 21 is detachably installed in the limiting cavity 221. In this way, when the electrode holder 22 is removed from the mounting groove 12, the atomizer core 21 can be removed from the mounting groove 12 at the same time, which makes it more convenient to remove and replace the atomizer core 21, thereby improving the convenience of disassembling and replacing the atomizer core 21.

[0055] It should be noted that there are also various ways to install the atomizer core 21 in the limiting cavity 221. For example, the atomizer core 21 can be detachably installed in the limiting cavity 221 by means of threaded connection, snap connection, magnetic connection, etc. For example, in one embodiment, Figure 6 As shown, the inner diameter of the limiting cavity 221 is slightly larger than the outer diameter of the atomizer core 21. A limiting boss 222 is protruded from the inner wall of the limiting cavity 221. The atomizer core 21 is supported on the limiting boss 222. That is, the atomizer core 21 is naturally placed in the limiting cavity 221. This makes it easier to remove and replace the atomizer core 21 from the electrode holder 22.

[0056] In order to prevent the atomizer core 21 from shaking, the distance between the limiting boss 222 and the groove bottom 121 of the installation groove 12 can be equal to or slightly smaller than the thickness of the atomizer core 21. Then, after assembly, the atomizer core 21 is clamped between the limiting boss 222 and the groove bottom 121 of the installation groove 12.

[0057] Alternatively, a compression structure (such as a limiting plate 244 on the airway component 24) can be provided to compress the atomizer core 21 to prevent the atomizer core 21 from shaking during use, thereby avoiding poor contact between the first atomizing electrode 231 and the first host electrode 210, or between the second atomizing electrode 232 and the electrode holder 22.

[0058] Optionally, in one embodiment, as Figure 6 As shown, the second atomizing electrode 232 is provided corresponding to the limiting boss 222, and the second atomizing electrode 232 is in conductive contact with the limiting boss 222. In this way, under the action of gravity of the atomizing core 21, the second atomizing electrode 232 and the electrode holder 22 can maintain contact, thereby avoiding poor contact between the second atomizing electrode 232 and the electrode holder 22.

[0059] What needs to be explained here is that the second atomizing electrode 232 and the limiting boss 222 can be provided in plurality, and the plurality of second atomizing electrodes 232 and the plurality of limiting bosses 222 correspond one to one, so that a stable limit can be formed for the atomizing core 21, and the conductive area between the heating element and the electrode holder 22 can be increased.

[0060] Alternatively, in one embodiment, as Figure 2 As shown, the limiting boss 222 extends along the inner circumference of the limiting cavity 221 , which not only supports the atomizer core 21 more stably, but also does not restrict the positional relationship between the atomizer core 21 and the electrode holder 22 , thereby improving assembly efficiency.

[0061] like Figure 2 As shown, the second atomizing electrode 232 extends along the limiting boss 222, that is, the second atomizing electrode 232 is also arranged in a ring shape. This can increase the supporting area of ​​the limiting boss 222 on the atomizing core 21, making the installation of the atomizing core 21 more stable, and can also increase the conductive area between the electrode holder 22 and the heating element 23, reduce the resistance, and improve the heating efficiency of the heating element 23.

[0062] Optionally, in one embodiment, as Figure 4As shown, the electrode holder 22 is inserted into the mounting groove 12, and the atomizer assembly 20 also includes an airway component 24. One end of the airway component 24 is detachably connected to the electrode holder 22, such as a threaded connection, a snap connection, a magnetic connection, etc., and the other end is snapped into the first airway 11. A third airway 241 is provided in the airway component 24, and one end of the third airway 241 is connected to the first airway 11, and the other end is connected to the second airway 213.

[0063] It can be understood that in this embodiment, the electrode holder 22 is installed in the mounting groove 12 by plugging, and is fixed on the shell 10 by snapping the airway piece 24 with the inner wall of the first airway 11. In this way, the atomizer assembly 20 can be installed in the shell 10 by insertion, and the atomizer assembly 20 can be removed from the shell 10 by pulling out, which further improves the convenience of disassembly and assembly of the atomizer assembly 20.

[0064] Among them, the specific method for clamping the air duct component 24 with the inner wall of the first air duct 11 is that the air duct component 24 can be interference-fitted into the first air duct 11, and then the entire atomizer assembly 20 can be inserted into the first air duct 11 with a little force during assembly, and the entire atomizer assembly 20 can be pulled out with a little force during disassembly.

[0065] Alternatively, optionally, in one embodiment, as Figure 5 As shown, the first air duct 11 includes a ventilation section 112, a clamping section 113 and an assembly section 114 connected in sequence along its axial direction, and the end of the ventilation section 112 away from the clamping section 113 forms a suction nozzle opening 111, the inner diameter of the clamping section 113 is larger than the inner diameter of the assembly section 114, and the end of the assembly section 114 away from the clamping section 113 is connected to the mounting groove 12.

[0066] like Figure 6 As shown, the airway component 24 includes a clamping head section 242 and a mounting rod section 243 connected in sequence along its axial direction. The outer diameter of the clamping head section 242 is larger than the outer diameter of the mounting rod section 243. Figure 4 As shown, the clamping head section 242 is adapted to be clamped in the clamping section 113, and the clamping head section 242 is configured to be able to squeeze and deform the inner wall of the assembly section 114 and clamp it into the clamping section 113, so that the air duct component 24 can be clamped and installed in the first air duct 11, and the mounting rod section 243 is installed in the assembly section 114. The third air duct 241 passes through the air duct component 24 along the axial direction of the first air duct 11, and one end of the third air duct 241 is connected to the ventilation section 112, and the other end is connected to the second air duct 213.

[0067] It can be understood that in this embodiment, when the atomizer assembly 20 needs to be installed in the shell 10, the airway piece 24 and the electrode holder 22 can be inserted into the first airway 11 through the notch 122 of the installation groove 12. Because the outer diameter of the clamping head section 242 is larger than the assembly section 114, when pushing the electrode holder 22 and the airway piece 24, you can push them inward with a little force, so that the clamping head section 242 squeezes and deforms the inner wall of the assembly section 114 and continues to move toward the ventilation section 112 until the clamping head section 242 is adapted to be clamped in the clamping section 113, and the installation of the atomizer assembly 20 is completed.

[0068] When the atomizer assembly 20 needs to be removed from the shell 10, the electrode holder 22 can be pulled outward, so that the electrode holder 22 drives the airway component 24 and the atomizer core 21 to move outward together. Because the outer diameter of the clamping head section 242 is larger than the assembly section 114, when pulling the electrode holder 22, it can be pulled outward with a little force, so that the clamping head section 242 squeezes and deforms the inner wall of the assembly section 114 and continuously moves toward the notch 122 of the installation groove until the entire atomizer assembly 20 is completely pulled out of the shell 10, and the disassembly of the atomizer assembly 20 is completed.

[0069] Optionally, in one embodiment, as Figure 6 As shown, the mounting rod section 243 further extends into the limiting cavity 221, and a limiting plate 244 is protruded from the outside of the mounting rod section 243. The limiting plate 244 is detachably connected to the limiting cavity 221. The specific connection method can be threaded connection, clamping connection, magnetic connection, etc., and the limiting plate 244 is pressed onto the atomizer core 21 to limit the atomizer core 21 from moving away from the limiting boss 222. That is, the atomizer core 21 is clamped between the limiting boss 222 and the limiting plate 244. This can improve the installation stability of the atomizer core 21 and prevent the atomizer core 21 from shaking during use.

[0070] Optionally, in one embodiment, as Figure 6 As shown, a first sealing member 25 is further provided between the limiting plate 244 and the atomizing core 21. The limiting plate 244 is provided with a first through hole 2441 at a position corresponding to the liquid outlet, and the first sealing member 25 is provided with a second through hole 251 at a position corresponding to the first through hole 2441. Figure 4 It is understood that after the aerosol generating liquid 30 flows out of the liquid storage tank 151 through the liquid outlet, it passes through the first through hole 2441 and the second through hole 251 in sequence and flows onto the liquid absorption surface 211 of the atomizing core 21 .

[0071] It can be understood that because the first sealing member 25 is provided between the limiting plate 244 and the atomizer core 21 , the aerosol generating liquid 30 can be prevented from leaking into the second air channel 213 or between the atomizer core 21 and the inner wall of the limiting cavity 221 , thereby improving the sealing performance of the atomizer assembly 20 .

[0072] Optionally, in one embodiment, the first sealing member 25 is sleeved outside the mounting rod section 243, and the outer diameter of the first sealing member 25 is greater than or equal to the outer diameter of the limiting plate 244. This can further seal the gap between the limiting plate 244 and the inner wall of the limiting cavity 221, as well as the gap between the atomizer core 21 and the inner wall of the limiting cavity 221, thereby further improving the sealing performance.

[0073] Optionally, in one embodiment, a second sealing member (not shown) is sandwiched between the outer peripheral wall of the atomizer core 21 and the inner peripheral wall of the limiting cavity 221, so that the gap between the outer peripheral wall of the atomizer core 21 and the inner peripheral wall of the limiting cavity 221 can be sealed to further improve the sealing performance.

[0074] Optionally, in one embodiment, as Figure 4 As shown, a third sealing member 26 is sandwiched between the outer peripheral wall of the electrode holder 22 and the inner peripheral wall of the mounting groove 12, so that the gap between the outer peripheral wall of the electrode holder 22 and the inner peripheral wall of the mounting groove 12 can be sealed to further improve the sealing performance.

[0075] Optionally, in one embodiment, as Figure 4 As shown, a fourth sealing member 27 is sandwiched between the outer peripheral wall of the clamping section 242 and the inner peripheral wall of the clamping section 113, so as to seal the gap between the outer peripheral wall of the electrode holder 22 and the inner peripheral wall of the mounting groove 12, thereby further improving the sealing performance.

[0076] In summary, you can refer to Figure 3 and Figure 6 In one embodiment of the present application, the atomizer assembly 20 includes an electrode holder 22 , an atomizer core 21 , a heating element 23 , an air passage element 24 , a first seal 25 , a third seal 26 and a fourth seal 27 .

[0077] The electrode holder 22 is a conductor, and the material of the electrode holder 22 can be copper, aluminum, copper alloy, aluminum alloy, etc. The overall shape of the electrode holder 22 is annular and cylindrical. The interior of the electrode holder 22 is hollow to form a limiting cavity 221. The limiting cavity 221 is mainly used to install the atomizer core 21, the first seal 25, and the lower end of the airway component 24 (i.e., the limiting plate 244). Therefore, the size and shape of the limiting cavity 221 need to adapt to the design of the atomizer core 21, the first seal 25, and the lower end of the airway component 24. In this embodiment, the shape of the atomizer core 21 is cylindrical, so the electrode holder 22 is also designed to be annular and cylindrical. The limiting cavity 221 is a cylindrical cavity, and the limiting cavity 221 passes through the electrode holder 22 along the axial direction of the electrode holder 22 to facilitate airflow through.

[0078] like Figure 6As shown, the inner wall of the limiting cavity 221 is further provided with a limiting boss 222, which is located at the lower end of the limiting cavity 221 (i.e., the end away from the airway member 24), and the limiting boss 222 extends along the circumferential direction of the limiting cavity 221. In this embodiment, the limiting boss 222 is used to support the atomizer core 21. When the atomizer core 21 is installed in the limiting cavity 221, the atomizer core 21 is supported on the periphery of the atomizer core 21. The limiting boss 222 is integrally formed with the electrode holder 22, that is, the material of the limiting boss 222 is also a conductive material such as copper, aluminum, copper alloy, aluminum alloy, etc. The second atomizing electrode 232 of the heating element 23 abuts against the limiting boss 222, thereby realizing a conductive connection between the heating element 23 and the electrode holder 22.

[0079] Still Figure 6 As shown, the outer periphery of the electrode holder 22 is provided with a sealing ring groove, and there can be multiple sealing ring grooves. The third sealing member 26 is a sealing ring, and there can also be multiple third sealing members 26. The multiple third sealing members 26 are sleeved and installed in the multiple sealing ring grooves one by one, and the third sealing members 26 protrude from the notch 122 of the sealing ring groove. Figure 4 As shown, when the electrode holder 22 is installed in the mounting groove 12 of the shell 10, the third seal 26 is pressed between the outer peripheral wall of the electrode holder 22 and the inner peripheral wall of the mounting groove 12, thereby sealing the gap between the electrode holder 22 and the shell 10 to avoid oil leakage.

[0080] In addition, if Figure 6 As shown, a positioning boss 223 is provided at the lower end of the outer peripheral wall of the electrode holder 22. The positioning boss 223 extends along the circumferential direction of the electrode holder 22. Figure 5 As shown, a positioning groove 123 is further provided at one end of the mounting groove 12 away from the first air channel 11. When the electrode holder 22 is installed in the mounting groove 12, the positioning boss 223 abuts against the inner wall of the positioning groove 123, which makes it easy to judge whether the electrode holder 22 is installed in place.

[0081] like Figure 6 As shown, the atomizer core 21 is a porous body, which can be specifically made of cotton, non-woven fabric, fiberglass, porous ceramic material, porous metal material, etc. The overall shape of the atomizer core 21 is cylindrical, and a second air channel 213 runs through the atomizer core 21. The second air channel 213 is used to communicate with the first air channel 11 in the shell 10 for air flow to flow through. The atomizer core 21 also has a relative liquid suction surface 211 and an atomizing surface 212. The liquid suction surface 211 is set away from the limiting boss 222 so as to face the liquid outlet of the liquid storage tank 151 after being assembled into the shell 10. The atomizing surface 212 is supported on the limiting boss 222, and a heating element 23 is fixed on the atomizing surface 212, as shown in FIG. Figure 2As shown, the heating element 23 has a second atomizing electrode 232 extending in a ring shape, and a first atomizing electrode 231 connected to the second atomizing electrode 232. After the atomizing assembly 20 is assembled, the second atomizing electrode 232 is located between the atomizing surface 212 and the limiting boss 222, and the first atomizing electrode 231 is exposed to the outside so that the first host 200 electrode on the host 200 can abut against the first atomizing electrode 231.

[0082] like Figure 6 As shown, the airway component 24 includes a mounting rod section 243, a clamping head section 242 connected to one end of the mounting rod section 243, and a limiting plate 244 connected to the other end of the mounting rod section 243. The outer diameters of the mounting rod section 243, the clamping head section 242 and the limiting plate 244 increase sequentially.

[0083] Among them, the clamping head section 242 is used to clamp and fit in the clamping section 113 of the first air channel 11, thereby achieving the fixation of the entire atomizer assembly 20, and the outer peripheral wall of the clamping head section 242 is also provided with a sealing ring groove, and there are multiple sealing ring grooves. The fourth sealing member 27 is a sealing ring, and there can also be multiple fourth sealing members 27. The multiple fourth sealing members 27 are installed one by one in the multiple sealing ring grooves, and the third sealing member 26 protrudes from the notch 122 of the sealing ring groove. Figure 4 As shown, when the clamping head section 242 is clamped into the clamping section 113 of the first air channel 11, the fourth sealing member 27 is pressed between the outer peripheral wall of the clamping head section 242 and the inner peripheral wall of the clamping section 113, thereby sealing the gap between the electrode holder 22 and the shell 10 to avoid air and oil leakage.

[0084] The mounting rod segment 243 is used to be installed in the assembly segment 114 in the first air duct 11 , so the length, outer diameter, etc. of the mounting rod segment 243 are adapted to the design of the assembly segment 114 of the first air duct 11 so that the outer wall of the mounting rod segment 243 just fits the inner wall of the assembly segment 114 .

[0085] The limiting plate 244 is circular, which allows it to compress the atomizer core 21 at various locations, making the installation of the atomizer core 21 more stable. After the atomizer assembly 20 is assembled, the upper end surface of the limiting plate 244 is flush with the upper end surface of the electrode holder 22, improving the appearance. Furthermore, to ensure that the aerosol-generating liquid 30 in the liquid reservoir 151 can flow to the atomizer core 21, a first through-hole 2441 is provided on the limiting plate 244 at the position corresponding to the liquid outlet. The first through-hole 2441 extends axially through the limiting plate 244, allowing the aerosol-generating liquid 30 to flow through the first through-hole 2441 to the atomizer core 21.

[0086] During assembly, the airway component 24 is connected to the electrode holder 22 via the limiting plate 244. Specifically, the limiting plate 244 can be detachably connected to the electrode holder 22 by means of threaded connection, interference fit, or snap fit. For example, the outer circumferential wall of the limiting plate 244 can be provided with external threads, and the inner circumferential wall of the limiting cavity 221 of the electrode holder 22 can be provided with internal threads, so that the airway component 24 can be connected to the electrode holder 22 by means of threaded connection. Alternatively, the limiting plate 244 can be inserted into the limiting cavity 221 by interference fit, which can also achieve a fixed connection between the airway component 24 and the electrode holder 22.

[0087] like Figure 6 As shown, the airway member 24 also has a third airway 241 running through it. Figure 4 The lower end of the third air channel 241 is used to communicate with the second air channel 213 in the atomizer core 21 , and the upper end of the third air channel 241 is used to communicate with the first air channel 11 in the shell 10 .

[0088] like Figure 6 As shown, a first sealing member 25 is provided between the limiting plate 244 and the atomizer core 21. The first sealing member 25 is annular and fits over the airway member 24. The limiting plate 244 presses the first sealing member 25 against the atomizer core 21, further enhancing the sealing effect between the atomizer core 21 and the electrode holder 22. Furthermore, a second through-hole 251 is provided on the first sealing member 25 at a position corresponding to the first through-hole 2441. This facilitates the flow of the aerosol-generating liquid 30 through the first and second through-holes 2441, 251, to the atomizer core 21.

[0089] Furthermore, based on the atomizer assembly 20 including the electrode holder 22, the atomizer core 21, the heating element 23, the airway component 24, the first sealing element 25, the third sealing element 26, and the fourth sealing element 27, when assembling the atomizer assembly 20, the heating element 23 can be first fixed to the atomizing surface 212 of the atomizer core 21 (of course, during production, the atomizer core 21 and the heating element 23 can be produced as an integral structure). The atomizer core 21 with the heating element 23 is then placed into the limiting cavity 221 of the electrode holder 22, so that the second atomizing electrode 232 of the heating element 23 is correspondingly supported on the limiting boss 222 in the limiting cavity 221. The first sealing element 25 is then placed over the lower end of the airway component 24, so that the second through hole 251 in the first sealing element 25 is in relative communication with the first through hole 2441 in the limiting plate 244. Next, the airway component 24 with the first seal 25 is secured to the limiting cavity 221 of the electrode holder 22, and the limiting plate 244 is secured to the inner wall of the limiting cavity 221 by screwing, interference fit, or snap-fitting, thereby achieving a fixed connection between the airway component 24 and the electrode holder 22. Finally, the third seal 26 is sleeved into the sealing ring groove outside the electrode holder 22, and the fourth seal 27 is sleeved into the sealing ring groove outside the clamping head section 242, completing the assembly of the atomizer assembly 20.

[0090] It should be noted that some of the above installation steps can be adjusted as needed. For example, the third seal 26 can be installed in the sealing ring groove outside the electrode seat 22 before the atomizer core 21 is placed into the electrode seat 22. For another example, the first seal 25 can be placed on the atomizer core 21 first, and then the limiting plate 244 of the airway component 24 can be fixed into the limiting cavity 221 and the first seal 25 can be pressed tightly.

[0091] Furthermore, when the atomizer assembly 20 of the above structure needs to be disassembled, the airway component 24 can be removed from the electrode holder 22 first. Specifically, when the limiting plate 244 of the airway component 24 is fixed to the limiting cavity 221 of the electrode holder 22 by a threaded connection, the airway component 24 can be removed by screwing the airway component 24. Alternatively, when the limiting plate 244 of the airway component 24 is inserted into the limiting cavity 221 of the electrode holder 22 by an interference fit, the airway component 24 can be removed from the electrode holder 22 by pulling it out. Then, the first sealing member 25 is removed from the limiting cavity 221, and then the atomizer core 21 is removed from the limiting cavity 221 of the electrode holder 22. The disassembly of the atomizer assembly 20 is completed.

[0092] The third seal 26 and the fourth seal 27 can be removed before or after any of the above disassembly steps, and are not specifically limited here. For example, before removing the airway component 24 from the electrode holder 22, the third seal 26 can be removed from the outer peripheral wall of the electrode holder 22, and the fourth seal 27 can be removed from the outer peripheral wall of the clamping head section 242.

[0093] It should be noted that, when assembling the atomizer 100 in the above embodiment, the specific assembly method includes:

[0094] Step S1: Install the atomizer core 21 into the limiting cavity 221 of the electrode holder 22. Figure 6 As shown, the inner diameter of the limiting cavity 221 is slightly larger than the outer diameter of the atomizer core 21. A limiting boss 222 is provided at one axial end of the limiting cavity 221. The limiting boss 222 is used to support the atomizer core 21. Therefore, during assembly, the atomizer core 21 is installed into the limiting cavity 221 from the end away from the limiting boss 222 until the atomizer core 21 abuts the limiting boss 222 and the atomizing surface 212 of the atomizer core 21 abuts the limiting boss 222.

[0095] Step S2: Connect the airway member 24 to the end of the electrode holder 22 away from the limiting boss 222. Figure 6 As shown, the airway component 24 can be connected to the electrode holder 22 by means of threaded connection, snap connection, magnetic connection, etc. It should be noted that when a limiting plate 244 is provided on the airway component 24, the limiting plate 244 can be detachably connected to the inner wall of the limiting cavity 221, and the limiting plate 244 is pressed onto the atomizer core 21 to make the installation of the atomizer core 21 more stable.

[0096] In addition, when the first sealing member 25 needs to be installed between the limiting plate 244 and the atomizer core 21, the first sealing member 25 can be first placed on the airway member 24, and then the first sealing member 25 and the airway member 24 are installed on the electrode holder 22. Alternatively, the first sealing member 25 can be first placed on the liquid absorption surface 211 of the atomizer core 21, and then the airway member 24 is connected to the electrode holder 22, and the limiting plate 244 is pressed onto the first sealing member 25.

[0097] Step S3: Insert the electrode holder 22 and the airway member 24 into the housing 10 from the notch 122 of the mounting groove 12 until the airway member 24 is engaged with the first airway 11. Figure 4 As shown, during operation, the end of the airway component 24 away from the electrode holder 22 is first inserted into the mounting groove 12 , and then the electrode holder 22 is continuously pushed until the airway component 24 is inserted into and snapped into the first airway 11 .

[0098] like Figure 5As shown, in one embodiment, the first air channel 11 includes a ventilation section 112, a clamping section 113 and an assembly section 114 connected in sequence along its axial direction. The inner diameter of the clamping section 113 is larger than the inner diameter of the assembly section 114. Figure 6 As shown, the air channel component 24 includes a clamping head section 242 and a mounting rod section 243 connected along its axial direction. The outer diameter of the clamping head section 242 is larger than the outer diameter of the mounting rod section 243 , and the clamping head section 242 is adapted to be engaged with the engaging section 113 .

[0099] When assembling, you can refer to Figure 4 The clamping head section 242 squeezes and deforms the inner wall of the assembly section 114 and is clamped into the clamping section 113. After the assembly is completed, the clamping head section 242 is adapted to be clamped in the clamping section 113, the mounting rod section 243 is located in the assembly section 114, and the electrode holder 22 is inserted into the mounting groove 12.

[0100] It can be seen that the assembly method of the atomizer 100 proposed in the present application is simple and convenient, which is conducive to improving the assembly efficiency during production and facilitating the reassembly after the user replaces the atomizer core 21, making it more convenient to use.

[0101] It should be noted that when disassembling the atomizer 100 in the above embodiment, the specific disassembly method includes:

[0102] Step S10: Pull out the atomizer assembly 20 from the notch 122 of the mounting groove 12 until the airway component 24 is completely pulled out from the housing 10. Figure 4 The electrode holder 22 may partially protrude from the notch 122 of the mounting groove 12, or a protrusion for pinching may be provided on the end of the electrode holder 22 away from the groove bottom 121, or a slight pinching gap may be left between part of the outer wall of the electrode holder 22 and part of the inner wall of the mounting groove 12, so that the user can pinch the electrode holder 22 with his hands or tools and pull the electrode holder 22 outward until the entire atomizer assembly 20 is completely pulled out of the shell 10.

[0103] It should be noted that if Figure 5 As shown, the first air channel 11 includes a ventilation section 112, a clamping section 113 and an assembly section 114 connected in sequence along its axial direction. The inner diameter of the clamping section 113 is larger than the inner diameter of the assembly section 114. Figure 6 As shown, the airway component 24 includes a clamping head section 242 and a mounting rod section 243 connected along its axial direction. The outer diameter of the clamping head section 242 is larger than the outer diameter of the mounting rod section 243. The clamping head section 242 is adapted to be clamped with the clamping section 113, and the mounting rod section 243 is located within the assembly section 114. During disassembly, the clamping head section 242 squeezes and deforms the inner wall of the assembly section 114, gradually withdrawing from the first airway 11.

[0104] Step S20: Remove the airway member 24 from the end of the electrode holder 22 away from the limiting boss 222. Figure 6 When the airway component 24 is connected to the electrode holder 22 by a threaded connection, the airway component 24 is removed from the electrode holder 22 by rotating the airway component 24. When the airway component 24 is connected to the electrode holder 22 by a snap fit (e.g., interference fit within the limiting cavity 221), the airway component 24 is removed from the electrode holder 22 by pulling it outward.

[0105] Step S30: Remove the atomizer core 21 from the end of the electrode holder 22 away from the limiting boss 222 to remove the limiting cavity 221. Figure 6 After the airway component 24 is removed from the electrode holder 22, the movement of the atomizer core 21 in the direction away from the limiting boss 222 is no longer restricted. Therefore, the atomizer core 21 can be directly removed from the end of the electrode holder 22 away from the limiting boss 222, and the atomizer core 21 can be replaced at this time.

[0106] It can be seen that the disassembly method of the atomizer 100 proposed in the present application is simple and convenient, which makes it very easy for the user to replace the atomizer core 21 and reduces the cost of use.

The main unit 200 is provided with a first main unit electrode 210 and a second main unit electrode 220.
