The terms used in the specification of the application are only for the purpose of describing specific embodiments and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0040] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[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 the attached Figure 1 To the attached Figure 11 As shown, an embodiment of the present application provides an atomizer, comprising:

[0043] A liquid cup 1, an atomizer core assembly 100 disposed in the liquid cup 1, a base 2 disposed on the liquid cup 1, and a seal 3 disposed 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 near the middle of the base 2 and for supporting the seal 3. The seal 3 is provided with an insertion portion 31 and is 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 near 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 the attached Figure 2 To the attached Figure 9 As shown, further, the atomizer core assembly 100 includes a liquid guide member 7, a through cavity 71 is defined in the liquid guide member 7, a second liquid guide member 10 is disposed 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 member 10. The sealing member 3 is connected to the liquid guide member 7 and / or the second liquid guide member 10, so that the sealing member 3 can support the atomizer core assembly 100, preventing the atomizer core assembly 100 from shaking during transportation and use, thereby causing liquid leakage. At the same time, the support structure 200 can provide better support, effectively preventing deformation of the sealing member 3, ensuring that the sealing member 3 is tightly connected to the liquid guide member 7 and / or the second liquid guide member 10, and preventing liquid leakage from the liquid cup 1.

[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 and other 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 simultaneously connected to the liquid guide member 7 and the second liquid guide member 10, 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 the attached Figure 2 To the attached Figure 9 As shown, the base 2 is further provided with an air inlet 21, and the support structure 200 includes at least one first protrusion 22 disposed around the air inlet 21. The support structure 200 near the middle of the base 2 can provide better support, effectively preventing the seal 3 from deforming and causing the seal 3 to fail to abut against the liquid cup 1, thereby preventing the liquid cup 1 from leaking.

[0047] Furthermore, each of the air inlet holes 21 is provided with a first raised portion 22 on all sides. The number of the first raised portions 22 can be two or four. The first raised portions 22 can be arranged around the air inlet hole 21 or symmetrically on both sides of the air inlet hole 21. Whether the first raised portions 22 are arranged around or symmetrically, they are all located near the middle of the base 2, which can better support the sealing member 3 and prevent the liquid cup 1 from leaking. At the same time, the sealing member 3 provides good support for the atomizer core assembly 100, which is firmly fixed and improves the aerosol matrix absorption effect of the atomizer core assembly 100.

[0048] Please see the attached Figure 2 To the attached Figure 9 As shown, the base 2 is further 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 aerosol matrix or condensed liquid from flowing into the electronic components below through the air inlet 21, thereby avoiding damage to the electronic components and improving the service life of the atomizer.

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

[0050] Furthermore, in this embodiment, the electrode 4 and the third protrusion 25 simultaneously abut 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 the attached Figure 2 To the attached Figure 9 As shown, further, a fourth protrusion 26 is provided in the accommodating cavity 23, and the electrode 4 is disposed in the fourth protrusion 26. This prevents aerosol matrix or condensate from flowing through the electrode 4 into the underlying electronic components, preventing the aerosol matrix and condensate from affecting the normal conductivity of the electrode 4 and damaging the electronic components, thereby increasing the service life of the atomizer. It is understood that the fourth protrusion 26 is provided with an electrode through-hole 261 for the electrode 4 to penetrate from bottom to top and electrically connect to the atomizer core assembly 100.

[0052] Please see the attached Figure 2 To the attached Figure 9 As shown, the electrode 4 is further provided with a fifth protrusion 27 on a side away from the third protrusion 25. This strengthens the fixing effect between the second protrusion 24 and the fourth protrusion 26, preventing aerosol matrix and condensed liquid from sticking to the electrode 4 and affecting the normal conductivity of the electrode 4. It also prevents aerosol matrix and condensed liquid from flowing through the air inlet 21 and the electrode 4 into the electronic components below, thereby avoiding damage to the electronic components and improving the service life of the atomizer.

[0053] Please see the attached Figure 2 To the attached Figure 9 As shown, further, the third protrusion 25 is 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 it. The arc-shaped structure of the third protrusion 25 increases the support range, effectively preventing deformation of the seal 3 and further preventing leakage from the liquid cup 1. Furthermore, by setting the first protrusion 22, the second protrusion 24, and the fifth protrusion 27 at different heights, different components can be supported, thereby supporting the seal 3. This effectively prevents deformation of the seal 3, which could result in the seal 3 failing to abut against the liquid cup 1, and further prevents leakage from the liquid cup 1.

[0057] Please see the attached Figure 2 To the attached Figure 5 As shown, the base 2 is further provided with a liquid absorbing member 5, which abuts against the sealing member 3 to support the sealing member 3. The liquid absorbing member 5 not only absorbs aerosol matrix and condensed liquid leaked into the base 2, but also provides additional support for the sealing member 3, effectively preventing accidents such as deformation of the sealing member 3 that cause the sealing member 3 to fail to abut against the liquid cup 1, further preventing the liquid cup 1 from leaking. At the same time, the base 2 provides good support for the liquid absorbing member 5, which is firmly fixed, thereby improving the effectiveness of the liquid absorbing member 5 in absorbing aerosol matrix.

[0058] Please see the attached Figure 3 To the attached Figure 4 and attached Figure 6 To the attached 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-absorbing 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 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, as well as the fifth protrusion 27 and the second protrusion 24, cooperate with each other to jointly support the sealing member 3.

[0059] For further information, please see the attached Figure 3 To the attached Figure 4 and attached Figure 6 To the attached 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-absorbing member 5, thereby jointly supporting the sealing member 3.

[0060] For further information, please 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, while 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 from supporting the sealing member 3 to supporting the liquid absorbent member 5. At the same time, by changing the function of the fifth protrusion 27 to support the sealing member 3, the support function of the sealing member 3 is maintained, thereby preventing the liquid cup 1 from leaking.

[0061] Furthermore, the first protrusion 22 is arranged between the air inlet 21 and the liquid absorbing member 5, and the third protrusion 25 is arranged between the electrode 4 and the liquid absorbing member 5. The first protrusion 22 and the third protrusion 25 can not only support the sealing member 3, but also position and shape the liquid absorbing member 5, so that the liquid absorbing member 5 can also provide another supporting force for the sealing member 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 located at both ends and both sides of the bottom wall of the accommodating cavity 23 to strengthen the support for the liquid absorbent member 5 .

[0063] Please see the attached Figure 3 To the attached Figure 5 and attached Figure 9 To the attached Figure 10 As shown, the base 2 is further provided with a flange 28, and the sealing member 3 is provided with a connecting portion 32. When connected, the end surface of the flange 28 abuts against the sealing member 3, and the connecting portion 32 is provided between the side surface of the flange 28 and the inner wall of the liquid cup 1. The flange 28 not only supports the sealing member 3, but also cooperates with the inner wall of the liquid cup 1 to clamp the connecting portion 32, so that the connecting portion 32 and the inner wall of the liquid cup 1 are tightly fitted, forming a sealed connection, and preventing the liquid cup 1 from leaking.

[0064] To go further, the base 2 and the liquid cup 1 are engaged. 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 engaged, the base 2 and the liquid cup 1 are engaged together, which is convenient for disassembly and assembly, and easy for assembly and replacement of accessories.

[0065] Please see the attached Figure 2 To the attached Figure 5 and attached Figure 11 As shown, the atomizer core assembly 100 further includes an atomizer tube 6, a liquid guide member 7 is provided in the atomizer tube 6, a liquid inlet hole 61 is provided on the atomizer tube 6, and an air guide passage 300 is provided on the liquid guide member 7. The liquid inlet hole 61 is correspondingly provided with the air guide passage 300. The corresponding arrangement of the liquid inlet hole 61 and the air guide passage 300 allows the atomizer core assembly 100 to share a single passage for liquid inlet and air supply, further improving the air supply efficiency and preventing problems such as "bubble stuck". 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, one end of which 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 into the atomizing pipe 12, and the inserting portion 31 is inserted into the liquid guide 7, so that the liquid cup 1, the mist outlet pipe 12, and the atomizing pipe 6 enclose a liquid storage tank 13.

[0067] Furthermore, the insertion portion 31 can be tubular, forming an interference fit with the tubular liquid-guiding member 7. In other embodiments, the insertion portion 31 can also have other irregular shapes. Furthermore, it should be noted that, since nebulizers and aerosol generating devices are often portable during actual use, they are inevitably placed in various positions by the user. Therefore, in many cases, the nebulizer is not in an upright position, but may be placed on its side or even upside down. However, when a user uses a nebulizer, the nebulizer is typically placed in a near-upright position because when inhaling an aerosol, the user tends to lower their head to inhale, rather than looking up. When the user inhales the aerosol, a large amount of liquid in the liquid-guiding member 7 is consumed, turning it into atomized vapor. This vapor is then mixed with air to form an aerosol, which is then discharged from the mist outlet of the mist outlet pipe. Therefore, liquid is continuously replenished from the liquid storage tank 13 to the liquid-guiding member 7, causing the liquid flow on the liquid-guiding member 7 to be the most intense when the user is in use, which can easily cause liquid to overflow from the liquid-guiding member 7. Therefore, when the atomizer is in the upright position, that is, in this position, the direction of the atomizer's mist discharge is approximately opposite to the direction of gravity, which has a blocking effect on the end of the liquid guide 7 close to the main body of the sealing member 3, thereby greatly improving the sealing effect of the atomizer. The portion of the base 2 inserted into 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, a sealing effect can be achieved. The matching method can be selected according to actual conditions.

[0068] Furthermore, the atomizer further includes a liquid filling cap 14. The housing 11 is provided with a liquid filling hole connected to the liquid storage tank 13. The liquid filling cap 14 covers the liquid filling hole. Therefore, when the liquid storage tank 13 is low on liquid, the liquid filling cap 14 can be opened to fill the liquid storage tank 13, allowing the atomizer to be reused.

[0069] Furthermore, the liquid-conducting member 7 is further provided with a second liquid-conducting member 10. Both the liquid-conducting member 7 and the second liquid-conducting member 10 are tubular. The liquid-conducting member 7 can be made of a fiber material or a porous body, wherein the fiber material can be plant fiber, animal fiber, mineral fiber, synthetic fiber, etc. The liquid-conducting member 7 can be made of a specific material such as cotton, non-woven fabric, fiberglass, porous ceramic, porous metal, etc. The second liquid-conducting member 10 can be made of a fiber material or a porous body, wherein the fiber material can be plant fiber, animal fiber, mineral fiber, synthetic fiber, etc. The second liquid-conducting member 10 can be made of a specific material such as cotton, non-woven fabric, fiberglass, porous ceramic, porous metal, 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 circumferential surface of the liquid guide member 7. The air guide passage 300 is directly provided on the outer circumferential surface of the liquid guide member 7, which has a simple structure and is easy to process. 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 drying out, and avoiding the generation of a burnt smell.

[0071] It can be understood that the depth of the air guiding passage 300 refers to the distance extending from the outer peripheral surface of the liquid guiding part 7 to the axial direction of the liquid guiding part 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 outer peripheral surface of the liquid guiding part 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 the attached Figure 5 and attached Figure 12 To the attached Figure 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 in the liquid cup 1, thereby avoiding the problem of poor liquid supply caused by the imbalance of the air pressure in the liquid guide member 7, preventing the atomizer core assembly 100 from dry burning, and avoiding the generation of a burnt smell. At the same time, the air guide passage 300 can be provided on either the liquid guide member 7 or the atomizer tube 6, which is flexible in design, improves the performance of the aerosol generating device, and enhances the user experience.

[0073] Specifically, the outer peripheral surface of the atomizing tube 6 corresponding to the air guide passage 300 is flat; and / or,

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

[0075] As attached Figure 12 As shown in FIG. 1 , the outer peripheral surface of the atomizing tube 6 is flat, which is beneficial to improving the appearance of the atomizing tube 6 and making it beautiful. Figure 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 facilitates the rotation of the air guide passage 300 to the required position during installation without reducing the thickness of the atomizer tube 6, thereby avoiding deformation and breakage of the atomizer tube 6.

[0076] It is understandable that Figure 12 As shown, the depth H of the air guiding passage 300 refers to the distance extending from the inner wall of the mounting cavity 62 of the atomizer tube 6 in the direction away from the axial center of the atomizer tube 6, that is, the distance extending outward, and the width D of the air guiding passage 300 refers to the size of the opening of the air guiding passage 300 on the inner wall of the mounting cavity 62 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.

[0077] Specifically, the air-guiding passage 300 has a depth of 0.05-2mm, a length of 10-12mm, and a width of 0.05-0.07mm. This appropriate size not only maintains the liquid-absorbing capacity of the liquid-guiding member 7 but also regulates the internal air pressure of the atomizer core assembly 100, avoiding problems such as poor liquid supply caused by pressure imbalance within the liquid-guiding member 7, which could result in incomplete atomization of the aerosol matrix inhaled by the user, leading to "bubble jamming" and other issues.

[0078] It can be understood that the depth of the air guide path 300 is any one of 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, and 2mm, or a range formed by any two of the values; the length of the air guide path 300 is 1 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, 12mm, or a range formed by any two of the values; the width of the air guide passage 300 is 0.05mm, 0.06mm, 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 provided with a first air supply groove 33, which is in communication with the air guide passage 300. This further increases the air supply channel, prevents bubble jamming, facilitates rapid liquid guide, and plays a role in moisturizing the atomizer core assembly 100. This improves the liquid supply capacity of the liquid guide member 7, prevents the atomizer core assembly 100 from dry burning, improves the performance of the atomizer, and enhances the user experience.

[0081] Furthermore, the first air supply 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 sections 332 are arranged in a direction away from the insertion portion 31, and air diffuses from the air intake section 331 to the diverging sections 332. External air enters the liquid cup 1 from the atomizer core assembly 100 to replenish the liquid cup 1 and prevent the generation of negative pressure. The plurality of diverging sections 332 facilitate the entry and diffusion of gas from multiple channels, which is beneficial for pressure relief, prevents the generation of negative pressure, improves air supply efficiency, facilitates rapid liquid guidance, prevents bubble jamming, and plays a role in moisturizing the atomizer core assembly 100, preventing the atomizer core assembly 100 from dry burning, thereby improving atomizer performance and enhancing the user experience.

[0082] Specifically, the air inlet section 331 and the diverging section 332 are arranged in a direction away from the center of the seal 3. Specifically, the air inlet section 331 is located near the center of the seal 3, while the diverging section 332 is relatively far from the center of the seal 3. The air inlet section 331 is located between the diverging section 332 and the center of the seal 3. The first air supply groove 33 is cup-shaped. The diverging section 332 extends away from the center of the seal 3, enhancing the pressure relief function of the first air supply groove 33, preventing the generation of negative pressure and improving 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 diverging section 332, so that the first air-supplying groove 33 is arranged corresponding to the liquid-guiding member 7, which facilitates the direct entry of gas into the liquid-guiding member 7, is beneficial to pressure relief, prevents the generation of negative pressure, improves the air-supplying efficiency, facilitates rapid liquid guidance, 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 near the air inlet section 331. This ensures that the seal 3 is provided with the diverging sections 332 with pressure relief functions in multiple directions, thereby ensuring the stability of the atomizer and preventing poor air release at certain angles, thereby preventing the negative pressure generated by liquid loss in the atomizer core assembly 100 from preventing the liquid from being 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 facilitates the air intake section 331 to merge the gases from 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 further provided with a second air supply groove 34. The second air supply groove 34 is in an elongated strip shape, further enhancing the pressure relief function of the seal 3, preventing the generation of negative pressure and avoiding problems such as bubble jamming.

[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 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.
