[0041] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0042] Please see attached Figure 1 To Attachment Fig.11 As shown, the embodiment of the present application provides an atomizer, comprising:

[0043] A liquid cup 1, an atomizer core assembly 100 arranged in the liquid cup 1, a base 2 arranged on the liquid cup 1, and a seal 3 arranged between the base 2 and the atomizer core assembly 100, wherein the seal 3 is provided with an insertion portion 31 connected to the atomizer core assembly 100, and the base 2 is provided with a support structure 200 close to the middle of the base 2 and used to support the seal 3. The seal 3 is provided with an insertion portion 31 and connected to the atomizer core assembly 100, so that the seal 3 can support the atomizer core assembly 100 to prevent the atomizer core assembly 100 from shaking during transportation and use, thereby causing leakage. At the same time, a support structure 200 for supporting the seal 3 is also provided on the base 2. The support structure 200 close to the middle of the base 2 can play a better supporting role, effectively preventing the seal 3 from deforming, resulting in the seal 3 being unable to abut against the liquid cup 1, and further preventing the liquid cup 1 from leaking. Compared with the prior art solution of connecting the seal with materials such as steel sheets, the use of parts is reduced, the cost is reduced, and the assembly efficiency is improved.

[0044] Please see attached Figure 2 To Attachment Fig. 9 As shown, further, the atomizer core assembly 100 includes a liquid guide member 7, a through cavity 71 is provided in the liquid guide member 7, a second liquid guide 10 is arranged in the through cavity 71, and the outer peripheral surface of the insertion portion 31 abuts against the through cavity 71 and / or the end surface of the insertion portion 31 abuts against the second liquid guide 10. The sealing member 3 is connected to the liquid guide member 7 and / or the second liquid guide 10, so that the sealing member 3 can support the atomizer core assembly 100 to prevent the atomizer core assembly 100 from shaking during transportation and use, thereby causing liquid leakage. At the same time, the supporting structure 200 can play a better supporting role, effectively prevent the deformation of the sealing member 3, ensure that the sealing member 3 is tightly connected to the liquid guide member 7 and / or the second liquid guide 10, and prevent the liquid cup 1 from leaking.

[0045] Furthermore, the insert 31 and the entire seal 3 can be made of soft rubber material, such as silicone or rubber, to improve the sealing effect. Of course, plastic or metal materials can also be used to improve the support for the atomizer core assembly 100, and at the same time, a certain sealing effect can also be achieved. It can be understood that the support structure 200 can better support the seal 3 made of soft rubber material. In this embodiment, the seal 3 is connected to the liquid guide member 7 and the second liquid guide member 10 at the same time, that is, the outer peripheral surface of the insert 31 is against the through cavity 71 and the end face of the insert 31 is against the second liquid guide member 10. The seal 3 and the liquid guide member 7 can be an interference fit to effectively prevent the liquid cup 1 from leaking.

[0046] Please see attached Figure 2 To Attachment Fig. 9 As shown, further, the base 2 is provided with an air inlet 21, and the support structure 200 includes at least one first protrusion 22 arranged around the air inlet 21. The support structure 200 near the middle of the base 2 can play a better supporting role, effectively preventing the occurrence of accidents such as the seal 3 being unable to abut against the liquid cup 1 due to deformation of the seal 3, and preventing the liquid cup 1 from leaking.

[0047] Furthermore, each of the air inlet holes 21 is provided with a first protrusion 22 around it, and the first protrusion 22 can be provided in two or four numbers, and the first protrusion 22 can be provided around the air inlet hole 21 or symmetrically provided on both sides of the air inlet hole 21. Whether the first protrusion 22 is provided around it or symmetrically provided, it is provided near the middle of the base 2, which can provide a better support for the sealing member 3 to prevent the liquid cup 1 from leaking; at the same time, the sealing member 3 has a good support effect on the atomizer core assembly 100, and the atomizer core assembly 100 is firmly fixed, thereby improving the effect of the atomizer core assembly 100 in absorbing the aerosol matrix.

[0048] Please see attached Figure 2 To Attachment Fig. 9 As shown, further, the base 2 is provided with a receiving cavity 23, a second protrusion 24 is provided in the receiving cavity 23, and the air inlet 21 is provided in the second protrusion 24, so that the end surface of the air inlet 21 is higher than the bottom wall of the receiving cavity 23. This prevents the liquid cup 1 from leaking liquid, and also prevents the aerosol matrix or condensed liquid from flowing into the lower electronic components through the air inlet 21, thereby avoiding damage to the electronic components and improving the service life of the atomizer.

[0049] Please see attached Figure 2 To Attachment Fig. 9 As shown, further, an electrode 4 is provided on the base 2, and a third protrusion 25 is further provided on one side of the electrode 4, and the electrode 4 and / or the third protrusion 25 abut against the seal 3 to support the seal 3. The electrode 4 can not only supply power to the atomizing core assembly 100, but also the electrode 4 has a certain size, which can provide another support for the seal 3, effectively preventing the seal 3 from deforming, resulting in the seal 3 failing to abut against the liquid cup 1, and further preventing the liquid cup 1 from leaking.

[0050] Furthermore, in this embodiment, the electrode 4 and the third protrusion 25 are simultaneously against the seal 3, further increasing the component supporting the seal 3, effectively preventing the seal 3 from deforming, and further preventing the liquid cup 1 from leaking.

[0051] Please see attached Figure 2 To Attachment Fig. 9 As shown, further, a fourth protrusion 26 is provided in the accommodating cavity 23, and the electrode 4 is provided in the fourth protrusion 26. It is prevented that the aerosol matrix or condensate etc. flow into the lower electronic components through the electrode 4, and the aerosol matrix and condensate are prevented from affecting the normal conductivity of the electrode 4, and damage to the electronic components is avoided, thereby improving the service life of the atomizer. It is understandable that the fourth protrusion 26 is provided with an electrode through hole 261 for the electrode 4 to penetrate from bottom to top and be electrically connected to the atomizing core assembly 100.

[0052] Please see attached Figure 2 To Attachment Fig. 9 As shown, further, a fifth protrusion 27 is provided on one side of the electrode 4 away from the third protrusion 25. The fixing effect between the second protrusion 24 and the fourth protrusion 26 is strengthened to prevent the aerosol matrix and condensate from being attached to the electrode 4, thereby affecting the normal conductivity of the electrode 4. At the same time, the aerosol matrix and condensate can be prevented from flowing into the electronic components at the bottom through the air inlet 21 and the electrode 4, thereby avoiding damage to the electronic components and improving the service life of the atomizer.

[0053] Please see attached Figure 2 To Attachment Fig. 9 As shown, further, the third protrusion 25 is in an arc-shaped structure; and / or,

[0054] The height of the first protrusion 22 is greater than the height of the second protrusion 24 or the first protrusion 22 and the second protrusion 24 are arranged at the same height; and / or,

[0055] The height of the fifth protrusion 27 is greater than or less than the height of the second protrusion 24 .

[0056] The third protrusion 25 also abuts against the seal 3 to support the seal 3. At the same time, the arc-shaped third protrusion 25 increases the support range, effectively preventing the seal 3 from deforming, and further preventing the liquid cup 1 from leaking. At the same time, by setting the first protrusion 22, the second protrusion 24 and the fifth protrusion 27 at different heights, different components can be supported to support the seal 3, effectively preventing the seal 3 from deforming, resulting in the seal 3 being unable to abut against the liquid cup 1, and further preventing the liquid cup 1 from leaking.

[0057] Please see attached Figure 2 To Attachment Figure 5 As shown, further, a liquid absorbing member 5 is further provided in the base 2, and the liquid absorbing member 5 abuts against the sealing member 3 to support the sealing member 3. The liquid absorbing member 5 can not only absorb the aerosol matrix and condensate leaked into the base 2, but also provide another support for the sealing member 3, effectively preventing the occurrence of accidents such as the sealing member 3 being unable to abut against the liquid cup 1 due to deformation of the sealing member 3, and further preventing the liquid cup 1 from leaking. At the same time, the base 2 has a good supporting effect on the liquid absorbing member 5, and the liquid absorbing member 5 is firmly fixed, thereby improving the effect of the liquid absorbing member 5 in absorbing the aerosol matrix.

[0058] Please see attached Figure 3 To Attachment Figure 4 and attached Figure 6 To Attachment Figure 8 As shown, further, when the height of the first protrusion 22 is greater than the height of the second protrusion 24, the first protrusion 22 is used to support the sealing member 3; when the first protrusion 22 and the second protrusion 24 are arranged at the same height, the first protrusion 22 is used to support the liquid absorbent member 5. When the height of the fifth protrusion 27 is greater than the height of the second protrusion 24, the fifth protrusion 27 is used to support the sealing member 3; when the height of the fifth protrusion 27 is less than the height of the second protrusion 24, the fifth protrusion 27 is used to strengthen the fixing effect between the second protrusion 24 and the fourth protrusion 26. By setting the first protrusion 22, the second protrusion 24 and the fifth protrusion 27 at different heights, different functions are achieved, and the first protrusion 22 and the second protrusion 24 and the fifth protrusion 27 and the second protrusion 24 cooperate with each other to jointly achieve the function of supporting the sealing member 3.

[0059] For further information, see the attached Figure 3 To Attachment Figure 4 and attached Figure 6 To Attachment Figure 7 As shown, in the first embodiment of the base 2, the height of the first protrusion 22 is greater than the height of the second protrusion 24, and the height of the fifth protrusion 27 is less than the height of the second protrusion 24, so that the first protrusion 22 is used to support the sealing member 3, and the fifth protrusion 27 is used to strengthen the fixing effect between the second protrusion 24 and the fourth protrusion 26. At the same time, the fifth protrusion 27 can be set to be the same height as the fourth protrusion 26, and the fourth protrusion 26 can also support the liquid absorbent member 5, thereby jointly supporting the sealing member 3.

[0060] For further information, see the attached Figure 7 As shown, in the second embodiment of the base 2, the first protrusion 22 and the second protrusion 24 are arranged at the same height, and the height of the fifth protrusion 27 is greater than the height of the second protrusion 24. The first protrusion 22 is used to support the liquid absorbent member 5, and the fifth protrusion 27 is used to support the sealing member 3. Compared with the first embodiment, the second embodiment changes the supporting function of the first protrusion 22, that is, from supporting the sealing member 3 to supporting the liquid absorbent member 5, and at the same time, by changing the function of the fifth protrusion 27, it supports the sealing member 3, thereby maintaining the supporting function of the sealing member 3 and preventing the liquid cup 1 from leaking.

[0061] Furthermore, the first protrusion 22 is arranged between the air inlet 21 and the liquid absorbent component 5, and the third protrusion 25 is arranged between the electrode 4 and the liquid absorbent component 5. The first protrusion 22 and the third protrusion 25 can not only support the sealing component 3, but also position and plasticize the liquid absorbent component 5, so that the liquid absorbent component 5 can also provide another supporting force for the sealing component 3.

[0062] Furthermore, a sixth protrusion 29 for supporting the liquid absorbent member 5 is further provided on the bottom wall of the accommodating cavity 23 . The sixth protrusion 29 is symmetrically disposed at both ends and both sides of the bottom wall of the accommodating cavity 23 to strengthen the supporting effect on the liquid absorbent member 5 .

[0063] Please see attached Figure 3 To Attachment Figure 5 and attached Fig. 9 To Attachment Fig.10 As shown, further, the base 2 is provided with a flange 28, and the sealing member 3 is provided with a connecting portion 32. When connected, the end face of the flange 28 abuts against the sealing member 3, and the connecting portion 32 is provided between the side of the flange 28 and the inner wall of the liquid cup 1. The flange 28 can not only support the sealing member 3, but also clamp the connecting portion 32 in combination with the inner wall of the liquid cup 1, so that the connecting portion 32 is closely fitted with the inner wall of the liquid cup 1 to form a sealed connection to prevent the liquid cup 1 from leaking.

[0064] To go further, the base 2 and the liquid cup 1 are snap-fitted. It can be understood that a buckle or a slot is provided on the base 2, and a slot or a buckle is provided on the liquid cup 1. When the buckle and the slot are snap-fitted, the base 2 and the liquid cup 1 are snap-fitted together, which is convenient for disassembly and assembly, and easy for replacement of accessories.

[0065] Please see attached Figure 2 To Attachment Figure 5 and attached Fig.11 As shown, further, the atomizer core assembly 100 further includes an atomizer tube 6, a liquid guide member 7 is disposed in the atomizer tube 6, a liquid inlet hole 61 is disposed on the atomizer tube 6, an air guide passage 300 is disposed on the liquid guide member 7, and the liquid inlet hole 61 is disposed correspondingly to the air guide passage 300. The corresponding arrangement of the liquid inlet hole 61 and the air guide passage 300 can make the atomizer core assembly 100 share a passage for liquid inlet and air replenishment, further improve the air replenishment efficiency, and prevent the generation of problems such as "bubble jamming". When negative pressure is generated in the atomizer core assembly 100, air can enter the atomizer core assembly 100 through the air guide passage 300 to adjust the internal air pressure of the atomizer core assembly 100, so that the air pressure in the atomizer core assembly 100 is balanced with the air pressure in the liquid cup 1, thereby improving the liquid supply capacity of the liquid guide member 7, thereby avoiding the problem of poor liquid supply caused by the imbalance of air pressure in the atomizer core assembly 100, preventing the atomizer core assembly 100 from dry burning, improving the performance of the atomizer, and enhancing the user experience.

[0066] Specifically, the liquid cup 1 may include a housing 11 and a mist outlet pipe 12, and one end of the mist outlet pipe 12 is provided with a mist outlet 121. The mist outlet pipe 12 is connected to the housing at one end of the mist outlet 121. The atomizing pipe 6 is partially inserted in the mist outlet pipe 12, and the inserting portion 31 is inserted in the liquid guide 7, so as to enclose the liquid cup 1, the mist outlet pipe 12 and the atomizing pipe 6 to form a liquid storage tank 13.

[0067] Furthermore, the insertion portion 31 may be tubular and have an interference fit with the tubular liquid guide 7. In other embodiments, the insertion portion 31 may also be in other irregular shapes. In addition, it should be noted that, since the atomizer and the aerosol generating device are often portable during actual use, they will inevitably be placed in various postures by the user. Therefore, in many cases, the atomizer is not in an upright position, but may be placed on its side or even inverted. However, when the user uses the atomizer, the atomizer is usually placed in an approximately upright position, because when the user inhales the aerosol, he often lowers his head to inhale, rather than looking up. When the user inhales the aerosol, a large amount of liquid in the liquid guide 7 is consumed, which becomes atomized vapor, and is mixed with air to become an aerosol and then discharged from the mist outlet of the mist outlet pipe. Therefore, liquid is constantly replenished from the liquid storage tank 13 to the liquid guide 7, so that when the user uses it, the liquid flow on the liquid guide 7 is the most intense, which also easily causes the liquid to overflow the liquid guide 7. Therefore, when the atomizer is in the upright position, that is, in this position, the mist outlet direction of the atomizer is approximately opposite to the gravity direction, which has a blocking effect on the end of the liquid guide 7 close to the main body of the sealing member 3, and the sealing effect of the atomizer can be greatly improved. The part of the base 2 inserted in the liquid guide 7 and the inner circumference of the liquid guide 7 can be an interference fit or at least a partial clearance fit. This is because the surface tension of the liquid is large, and even with a clearance fit, it can also have a blocking effect. The matching method can be selected according to the actual situation.

[0068] Furthermore, the atomizer further comprises a liquid injection cap 14. The housing 11 is provided with a liquid injection hole connected to the liquid storage bin 13. The liquid injection cap 14 is disposed on the liquid injection hole. Thus, when the liquid in the liquid storage bin 13 is insufficient, the liquid injection cap 14 can be opened to inject liquid into the liquid storage bin 13. Thus, the atomizer can be reused repeatedly.

[0069] Furthermore, the liquid-conducting member 7 is further provided with a second liquid-conducting member 10, and the liquid-conducting member 7 and the second liquid-conducting member 10 are both tubular. The liquid-conducting member 7 may be made of a fiber material or a porous body, wherein the fiber material may be plant fiber, animal fiber, mineral fiber, synthetic fiber, etc. The liquid-conducting member 7 may be made of a specific material such as cotton, non-woven fabric, glass fiber, porous ceramic material, porous metal material, etc. The second liquid-conducting member 10 may be made of a fiber material or a porous body, wherein the fiber material may be plant fiber, animal fiber, mineral fiber, synthetic fiber, etc. The second liquid-conducting member 10 may be made of a specific material such as cotton, non-woven fabric, glass fiber, porous ceramic material, porous metal material, etc.

[0070] Specifically, the air guide passage 300 is configured as an air guide groove, which is provided on the liquid guide member 7 and located on the outer peripheral surface of the liquid guide member 7. The air guide passage 300 is directly provided on the outer peripheral surface of the liquid guide member 7, has a simple structure, and is convenient for processing. The air guide passage 300 can timely adjust the internal air pressure of the atomizer core assembly 100, so that the air pressure in the liquid guide member 7 is balanced with the air pressure in the liquid cup 1, thereby avoiding the problem of poor liquid supply caused by the imbalance of air pressure in the liquid guide member 7, preventing the atomizer core assembly 100 from dry burning, and avoiding the generation of burnt smell.

[0071] It can be understood that the depth of the air guiding passage 300 refers to the distance extending from the peripheral surface of the liquid guiding component 7 to the axial direction of the liquid guiding component 7, that is, the distance extending inward, and the width of the air guiding passage 300 refers to the size of the opening of the air guiding passage 300 on the peripheral surface of the liquid guiding component 7 perpendicular to the extension direction of the depth of the air guiding passage 300, that is, the distance between the two side walls of the air guiding passage 300.

[0072] As attached Figure 2 To Attachment Figure 5 and attached Fig.12 To Attachment Fig.13 As shown, further, the atomizer tube 6 is provided with a mounting cavity 62 for accommodating the liquid guide member, and the air guide passage 300 is configured as an air guide groove, which can also be provided on the atomizer tube 6 and located on the inner wall of the mounting cavity 62 on the inner side of the atomizer tube 6. The air guide passage 300 can timely adjust the internal air pressure of the atomizer core assembly 100, so that the air pressure in the liquid guide member 7 is balanced with the air pressure of the liquid cup 1, thereby avoiding the problem of poor liquid supply caused by the imbalance of air pressure in the liquid guide member 7, preventing the atomizer core assembly 100 from dry burning, and avoiding the generation of burnt smell. At the same time, the air guide passage 300 can be provided on the liquid guide member 7 or on the atomizer tube 6, with flexible design, improving the performance of the aerosol generating device, and enhancing the user experience.

[0073] Specifically, the outer peripheral surfaces of the atomizing tube 6 and the air guide passage 300 are flat; and / or,

[0074] The outer peripheral surface of the atomizing tube 6 corresponding to the air guide passage 300 is arranged in a convex shape.

[0075] As attached Fig.12 As shown in the figure, the outer peripheral surface of the atomizing tube 6 is flat, which is beneficial to improve the appearance of the atomizing tube 6 and make it beautiful. Fig.13As shown, the outer peripheral surface of the atomizer tube 6 is arranged in a convex shape, so the position of the air guide passage 300 located in the installation cavity 62 can be accurately understood from the appearance of the atomizer tube 6, which is convenient for rotating the air guide passage 300 to the required position during installation, and at the same time, the thickness of the atomizer tube 6 will not be thinned, thereby avoiding deformation and breakage of the atomizer tube 6.

[0076] It is understandable that if Fig.12 As shown, the depth H of the air guide passage 300 refers to the distance extending from the inner wall of the mounting cavity 62 of the atomizer tube 6 in the axial direction away from the atomizer tube 6, that is, the distance extending outward, and the width D of the air guide passage 300 refers to the size of the opening of the air guide passage 300 on the inner wall of the mounting cavity 62 perpendicular to the extension direction of the depth of the air guide passage 300, that is, the distance between the two side walls of the air guide passage 300.

[0077] Specifically, the depth of the air guide passage 300 is 0.05-2 mm, the length is 10-12 mm, and the width is 0.05-0.07 mm. The appropriate size can not only maintain the good liquid absorption capacity of the liquid guide member 7, but also adjust the internal air pressure of the atomizer core assembly 100, so as to avoid the problem of poor liquid supply caused by the imbalance of air pressure in the liquid guide member 7, which causes the aerosol matrix inhaled by the user to be not completely atomized, thereby causing problems such as "bubble jamming".

[0078] It can be understood that the depth of the air guide passage 300 is 0.05mm, 0.06mm, 0.07mm, 0.08mm, 0.09mm, 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, or a range formed by any two of the values; the length of the air guide passage 300 is 1 The width of the air guide passage 300 is any one of 0.1mm, 10.2mm, 10.3mm, 10.4mm, 10.5mm, 10.6mm, 10.7mm, 10.8mm, 10.9mm, 11mm, 11.1mm, 11.2mm, 11.3mm, 11.4mm, 11.5mm, 11.6mm, 11.7mm, 11.8mm, 11.9mm, and 12mm, or a range formed by any two of the values. The width of the air guide passage 300 is any one of 0.05mm, 0.06mm, and 0.07mm, or a range formed by any two of the values.

[0079] Specifically, the air guiding passage 300 has a depth of 1 mm, a length of 11 mm, and a width of 0.06 mm, thereby improving the air guiding effect of the liquid guiding member 7 .

[0080] Furthermore, the sealing member 3 is also provided with a first air replenishing groove 33, which is communicated with the air guiding passage 300. Further increasing the air replenishing channel prevents bubble jamming, facilitates rapid liquid guiding, plays a role in moistening the atomizing core assembly 100, improves the liquid supply capacity of the liquid guiding member 7, prevents the atomizing core assembly 100 from dry burning, improves the atomizer performance, and enhances the user experience.

[0081] Furthermore, the first air replenishing groove 33 is provided with an air intake section 331 and a plurality of diverging sections 332 communicating with the air intake section 331. The air intake section 331 and the diverging section 332 are arranged in a direction away from the insertion portion 31, and air diffuses toward the diverging section 332 through the air intake section 331. External air enters the liquid cup 1 from the atomizer core assembly 100 to replenish air in the liquid cup 1 to prevent negative pressure. The plurality of diverging sections 332 facilitate the entry and diffusion of gas from multiple channels, which is conducive to pressure relief, prevents negative pressure, improves air replenishment efficiency, facilitates rapid liquid conduction, prevents bubble jamming, moisturizes the atomizer core assembly 100, prevents the atomizer core assembly 100 from dry burning, improves atomizer performance, and enhances user experience.

[0082] Furthermore, the air inlet section 331 and the divergent section 332 are arranged in a direction away from the middle of the seal 3, that is, the air inlet section 331 is close to the middle of the seal 3, and the divergent section 332 is relatively far from the middle of the seal 3, and the air inlet section 331 is located between the divergent section 332 and the middle of the seal 3. The first air replenishing groove 33 is cup-shaped. The divergent section 332 extends in a direction away from the middle of the seal 3, which enhances the pressure relief function of the first air replenishing groove 33, prevents the generation of negative pressure, and improves the user experience.

[0083] Furthermore, the projection of the liquid guiding member 7 in the axial direction is located on the air inlet section 331 and the divergent section 332, so that the first air supply groove 33 is arranged corresponding to the liquid guiding member 7, which is convenient for gas to directly enter the liquid guiding member 7, is conducive to pressure relief, prevents the generation of negative pressure, improves the air supply efficiency, is conducive to rapid liquid conduction, prevents bubble jamming, plays a role in moisturizing the atomizer core assembly 100, prevents the atomizer core assembly 100 from dry burning, improves the performance of the atomizer, and enhances the user experience.

[0084] Specifically, the number of the diverging sections 332 is greater than the number of the air inlet sections 331, and the multiple diverging sections 332 intersect at a position close to the air inlet section 331. The seal 3 is provided with the diverging sections 332 with a pressure relief function in multiple directions, thereby ensuring the stability of the atomizer, avoiding poor air relief effect at some angles, and avoiding the negative pressure generated after the loss of liquid in the atomizer core assembly 100, which causes the liquid to be unable to be transported to the heating element of the atomizer core assembly 100 through the liquid guide 7.

[0085] Specifically, the width of the air intake section 331 is greater than the width of the diverging section 332. This is beneficial for the air intake section 331 to merge the gases of several diverging sections 332, thereby enhancing the pressure relief function of the first air replenishing groove 33, preventing the generation of negative pressure, and improving the user experience.

[0086] Furthermore, the seal 3 is provided with a second air replenishing groove 34. The second air replenishing groove 34 is in a long strip structure, which further increases the pressure relief function of the seal 3, prevents the generation of negative pressure, and avoids problems such as bubble jam.

[0087] Based on the above-mentioned atomizer, an embodiment of the present application provides an aerosol generating device, including a power supply assembly and the atomizer, wherein the power supply assembly is detachably connected or fixedly connected to the atomizer, and the seal 3 is provided with an insertion portion 31 and connected to the atomizer core assembly 100, so that the seal 3 can support the atomizer core assembly 100 to prevent the atomizer core assembly 100 from shaking during transportation and use, thereby causing leakage. At the same time, a support structure 200 for supporting the seal 3 is also provided on the base 2. The support structure 200 close to the middle part of the base 2 can play a better supporting role, effectively preventing the seal 3 from deforming, resulting in the seal 3 being unable to abut against the liquid cup 1, and the like, and further preventing the liquid cup 1 from leaking. Compared with the prior art solution of connecting the seal with materials such as steel sheets, the use of parts is reduced, the cost is reduced, and the assembly efficiency is improved.

The preferred embodiments of the present application are given in the accompanying drawings, but they do not limit the patent scope of the present application.
