Description

[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202411436275X, filed on October 15, 2024, entitled “Atomizing Module and Aerosol Generating Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of electronic atomization technology, and in particular to an atomization module and an aerosol generating device. Background Technology

[0004] An aerosol generator is an electronic device that atomizes stored e-liquids, medications, or other liquids into aerosols through electric heating. Currently, commercially available aerosol generators typically include an atomizing component for generating aerosols and a power supply component for providing power to the atomizing component. The atomizing component usually includes a reservoir for storing the atomizing liquid and an atomizing core for heating and atomizing the liquid. The atomizing liquid in the reservoir is conducted to the atomizing core through capillary action. During inhalation, the power supply component provides power to the atomizing core, causing it to heat up. The heat generated by the atomizing core atomizes the liquid into an aerosol that the user can inhale.

[0005] In related technologies, most atomizing components are disposable products. Once the atomizing liquid in the reservoir is consumed by the atomizing core, the user cannot replenish the liquid, causing the entire atomizing component to be scrapped and unusable. This not only increases the user's operating costs but is also detrimental to the environment. Summary of the Invention

[0006] The main objective of this application is to provide an atomizing module and an aerosol generating device, which aims to solve the technical problem in related technologies that atomizing components cannot be reused after the atomizing liquid is consumed.

[0007] To achieve the above objectives, in a first aspect, this application provides an atomizing module for use in conjunction with a power supply module, the atomizing module comprising:

[0008] The first housing has a nozzle mounting port on its top and a first sidewall along its circumference for detachable connection with the power supply module. The first sidewall is located between the top surface and the bottom surface of the first housing.

[0009] A liquid storage cup is installed inside the first housing. The liquid storage cup has an atomization channel and a liquid storage chamber for storing atomized liquid inside. The top of the liquid storage cup has an injection hole that communicates with the liquid storage chamber. The injection hole is arranged opposite to the nozzle mounting port.

[0010] The atomizing core is installed in the atomizing channel and is connected to the liquid storage chamber;

[0011] A first electrode assembly, exposed on the first sidewall and electrically connected to the atomizing core, is used for electrical connection to the power supply module. Specifically, the first electrode assembly is used for electrical contact with a second electrode assembly of the power supply module.

[0012] The nozzle assembly includes a nozzle body having a suction channel and a seal disposed within the nozzle body. The nozzle body is detachably connected to the nozzle mounting port, and the suction channel is connected to the atomization channel. The seal closes the liquid injection hole.

[0013] In some embodiments, the nozzle body is rotatably connected to the nozzle mounting port and can rotate relative to the first housing to a first position and a second position. The outer peripheral wall of the nozzle body has a limiting protrusion, and the inner peripheral wall of the nozzle mounting port has a stepped portion. The stepped portion has a notch through which the limiting protrusion can pass. When the nozzle body rotates to the first position, the sealing member covers the opening of the injection hole, and the limiting protrusion is misaligned with the notch so that the limiting protrusion can abut against the side surface of the stepped portion facing the liquid storage cup. When the nozzle body rotates to the second position, the limiting protrusion is opposite to the notch so that the limiting protrusion can pass through the notch in a direction away from the liquid storage cup.

[0014] In some embodiments, a first blocking portion is provided on the side surface of the stepped portion facing the liquid storage cup. When the nozzle body rotates to the first position, the limiting protrusion abuts against the first blocking portion.

[0015] In some embodiments, a second blocking portion is provided on the side of the stepped portion facing the liquid storage cup. The second blocking portion has a blocking surface flush with the inner wall of the notch. When the suction nozzle body is rotated to the second position, the limiting protrusion abuts against the blocking surface.

[0016] In some embodiments, the top of the liquid storage cup is further provided with a vent hole communicating with the liquid storage cavity, the vent hole is spaced apart from the liquid injection hole, and the sealing member covers the opening of the vent hole.

[0017] In some embodiments, the outer surface of the nozzle body is provided with an exposed first marking groove, and the outer surface of the first housing is provided with a second marking groove adjacent to the nozzle mounting port. When the nozzle body is rotated to the second position, the first marking groove and the second marking groove are aligned.

[0018] In some embodiments, the first housing is made of a biodegradable material.

[0019] In some embodiments, the stepped portion has an anti-rotation protrusion on the side facing the liquid storage cup, and the limiting protrusion has an anti-rotation groove adapted to the anti-rotation protrusion on the side surface facing away from the outer peripheral wall of the suction nozzle body. The side surface of the anti-rotation protrusion facing the suction nozzle body and the groove wall surface of the anti-rotation groove are both arc surfaces. At least one of the limiting protrusion and the anti-rotation protrusion is made of plastic. When the suction nozzle body rotates to the first position, the anti-rotation protrusion engages with the anti-rotation groove.

[0020] Secondly, this application also provides an aerosol generating device, which includes a power supply module and an atomizing module as described in any of the above embodiments. The atomizing module further includes a first electrode assembly electrically connected to the atomizing core, and the first electrode assembly is exposed on the first sidewall.

[0021] The power supply module includes a second housing, a battery, a second control circuit board, and a second electrode assembly. The battery and the second control circuit board are both installed inside the second housing. The second housing has a second sidewall along its circumference, located between the top surface and the bottom surface of the second housing. The second electrode assembly is exposed on the second sidewall. The second control circuit board is electrically connected to the battery and the second electrode assembly, respectively. The second sidewall is detachably connected to the first sidewall, and the second electrode assembly is in electrical contact with the first electrode assembly.

[0022] Compared with the prior art, this application has at least the following beneficial effects:

[0023] In the technical solution of this application, the top of the first housing is provided with a nozzle mounting port, and the nozzle body is detachably connected to the nozzle mounting port. The top of the liquid storage cup is provided with a liquid injection hole communicating with the liquid storage chamber. The liquid injection hole is opposite to the nozzle mounting port, and the inside of the nozzle body is provided with a sealing element for sealing the liquid injection hole. With this configuration, when the atomizing liquid in the liquid storage cup is consumed by the atomizing core and it is necessary to replenish the atomizing liquid in the liquid storage chamber, the entire nozzle assembly can be detached from the first housing to expose the liquid injection hole. At this time, the atomizing liquid can be injected into the liquid storage chamber through the liquid injection hole to replenish the atomizing liquid. After replenishing the atomizing liquid, the nozzle body is installed back into the nozzle mounting port of the first housing so that the sealing element seals the liquid injection hole, thus allowing the atomizing module to continue to be used. Therefore, it can be seen that after the atomizing liquid in the storage chamber is consumed by the atomizing core, the atomizing module provided in this application embodiment can be replenished through the injection hole, so that it can be reused. Compared with traditional disposable atomizing components, the atomizing module provided in this application embodiment not only helps to reduce the user's usage cost, but also helps to protect the environment.

[0024] Furthermore, in the technical solution of this application, the sealing element not only effectively reduces the risk of leakage of atomized liquid from the injection hole in the liquid storage chamber, but also, since the sealing element is located inside the nozzle body and does not protrude from the inside of the nozzle body, the user's hands are unlikely to come into contact with the sealing element during the disassembly and assembly of the nozzle body, thereby effectively preventing the user's hands from being contaminated with atomized liquid adhering to the sealing element and affecting the user's experience.

[0056] Please refer to Figure 1-6 This application provides an atomizing module 1, which includes a first housing 11, an atomizing core 14, a mouthpiece assembly 15, and a liquid storage cup 10 installed in the first housing 11, wherein:

[0057] The top of the first housing 11 is provided with a suction nozzle mounting port 110. It should be noted that, in specific implementations, the first housing 11 can be a one-piece structure or a modular structure assembled from different housing structures. Its specific structural form can be determined according to actual usage needs, and this embodiment does not impose specific limitations in this regard. Furthermore, the material of the first housing 11 can be a biodegradable material (such as polylactic acid, polybutylene terephthalate, polyhydroxyalkanoates, polybutylene succinate, etc.), plastic, or metal, depending on actual usage requirements. This embodiment does not impose specific limitations on the specific material of the first housing 11.

[0058] The liquid storage cup 10 has an atomization channel 1031 and a liquid storage chamber 1041 for storing atomizing liquid inside. The top of the liquid storage cup 10 has an injection hole 1012 that communicates with the liquid storage chamber 1041. The injection hole 1012 is arranged opposite to the nozzle mounting port 110.

[0059] The mouthpiece assembly 15 includes a mouthpiece body 151 with a suction channel 150 and a seal 152 disposed in the mouthpiece body 151. The mouthpiece body 151 is detachably connected to the mouthpiece mounting port 110. The seal 152 closes the liquid injection hole 1012. The suction channel 150 is connected to the atomization channel 1031. When the user bites the mouthpiece body 151 to suck, a suction airflow is formed in the path connecting the atomization channel 1031 and the suction channel 150.

[0060] It should be noted that, in specific implementations, the material of the sealing element 152 can be silicone, rubber, silicone rubber, absorbent cotton (such as sponge or fiber cotton), etc., as long as it can meet the usage requirements. This embodiment does not impose specific restrictions on this.

[0061] It should also be noted that the detachable connection between the nozzle body 151 and the first housing 11 can be a snap-fit ​​connection, a threaded connection, a plug-in connection, etc., as long as it meets the usage requirements. This embodiment does not impose specific limitations on this. In addition, the material of the nozzle body 151 can be plastic or the like, which can be determined according to actual usage requirements. This embodiment does not impose specific limitations on the specific material of the nozzle body 151.

[0062] The atomizing core 14 is installed in the atomizing channel 1031 so that the aerosol generated by the atomizing core 14 can be carried away by the suction airflow formed in the atomizing channel 1031 and discharged to the mouthpiece body 151 for the user to inhale. In addition, the atomizing core 14 is connected to the liquid storage chamber 1041 so that the atomizing core 14 can draw atomizing liquid from the liquid storage chamber 1041 for heating and atomization to generate aerosol.

[0063] In this embodiment, based on the above structural design, when the atomizing liquid in the storage cup 10 is consumed by the atomizing core 14 and it is necessary to replenish the atomizing liquid into the storage chamber 1041, the nozzle body 151 can be detached from the first housing 11 (during this process, the sealing element 152 will also be detached from the first housing 11 along with the nozzle body 151), exposing the injection hole 1012. At this time, the atomizing liquid can be injected into the storage chamber 1041 through the injection hole 1012 (in some specific application scenarios, the container holding the atomizing liquid can be filled with atomizing liquid). The nozzle of the liquid injection bottle extends into the nozzle mounting port 110 and is inserted into the injection hole 1012. Then, by tilting or squeezing the injection bottle, the atomizing liquid in the injection bottle is injected into the storage chamber 1041 of the storage cup 10, thereby replenishing the atomizing liquid. After replenishing the atomizing liquid, the nozzle body 151 is reinstalled back into the nozzle mounting port 110 of the first housing 11, so that the sealing member 152 seals the injection hole 1012, allowing the atomizing module 1 to continue to be used. Therefore, the atomizing module 1 provided in this embodiment can be replenished with atomizing liquid through the injection hole 1012 after the atomizing liquid in the storage chamber 1041 is consumed by the atomizing core 14, allowing for repeated use. Thus, the atomizing module 1 provided in this embodiment not only helps reduce user costs but also benefits the environment.

[0064] Furthermore, in this embodiment, the sealing element 152 not only effectively reduces the risk of leakage of the atomized liquid in the liquid storage chamber 1041 from the injection hole 1012, but also, since the sealing element 152 is located inside the nozzle body 151 and does not protrude from the inside of the nozzle body 151, the user's hands are unlikely to come into contact with the sealing element 152 during the disassembly and assembly of the nozzle body 151, thereby effectively preventing the user's hands from getting contaminated with the atomized liquid adhering to the sealing element 152 and affecting the user's experience.

[0065] It should be noted that, in some optional embodiments, the seal 152 can seal the injection hole 1012 by partially inserting it into the injection hole 1012 (in this case, the seal 152 usually has a plunger portion that can be inserted into the injection hole 1012). In other optional embodiments, the seal 152 can also seal the injection hole 1012 by covering the opening of the injection hole 1012. The specific method by which the seal 152 seals the injection hole 1012 can be determined according to actual usage needs, and this embodiment does not impose specific limitations on this. Preferably, the sealing member 152 seals the injection hole 1012 by covering its opening. Compared to sealing the injection hole 1012 by inserting the plunger portion of the sealing member 152 into the injection hole 1012, the sealing member 152 does not insert into the injection hole 1012. Therefore, during the process of replenishing the atomizing liquid and installing the nozzle body 151 back into the nozzle mounting port 110 of the first housing 11, the sealing member 152 is less likely to force the air in the injection hole 1012 into the storage chamber 1041. This effectively reduces the risk of the atomizing liquid in the storage chamber 1041 leaking from the connection point between the storage chamber 1041 and the atomizing core 14 due to the increased air pressure caused by the air in the injection hole 1012 being forced into the storage chamber 1041 by the sealing member 152.

[0066] Furthermore, in some optional embodiments of this application, the nozzle body 151 and the first housing 11 can be detachably connected in the following manner:

[0067] Please refer to Figure 1-8 The nozzle body 151 is rotatably connected to the nozzle mounting port 110 and can rotate relative to the first housing 11 to a first position and a second position. A limiting protrusion 1512 protrudes from the outer peripheral wall of the nozzle body 151, and a stepped portion 112 protrudes from the inner peripheral wall of the nozzle mounting port 110. A notch 1120 is provided on the stepped portion 112 to allow the limiting protrusion 1512 to pass through.

[0068] like Figure 6-7As shown, when the nozzle body 151 is rotated to the first position, the seal 152 covers the opening of the injection hole 1012, and the limiting protrusion 1512 is misaligned with the notch 1120 so that the limiting protrusion 1512 can abut against the side surface of the step portion 112 facing the liquid storage cup 10. At this time, even if the user applies a force to the nozzle body 151 in a direction away from the liquid storage cup 10, the limiting protrusion 1512 of the nozzle body 151 will be blocked by the step portion 112 of the first housing 11, so the user cannot pull out the nozzle body 151. This allows the nozzle body 151 to be stably held at the nozzle mounting port 110 of the first housing 11, preventing the nozzle body 151 from accidentally coming off the nozzle mounting port 110 of the first housing 11 and affecting the user's experience.

[0069] like Figure 3-4 and Figure 8 As shown, when the nozzle body 151 rotates to the second position, the limiting protrusion 1512 is aligned with the notch 1120 so that the limiting protrusion 1512 can pass through the notch 1120 in the direction away from the liquid storage cup 10. At this time, if the user applies a force to the nozzle body 151 in the direction away from the liquid storage cup 10, the limiting protrusion 1512 of the nozzle body 151 will not be blocked by the notch 1120 of the step portion 112 because it is aligned with the notch 1120 of the step portion 112. Therefore, the limiting protrusion 1512 can pass through the notch 1120 in the direction away from the liquid storage cup 10, so that the nozzle body 151 can be separated from the nozzle mounting port 110 of the first housing 11, so that the liquid injection hole 1012 can be exposed, so that new atomizing liquid can be injected into the liquid storage cavity 1041 through the liquid injection hole 1012.

[0070] In this embodiment, based on the above structural design, when the atomizing liquid in the storage chamber 1041 is consumed by the atomizing core 14 and needs to be replenished, the nozzle body 151 can be rotated from the first position to the second position, so that the limiting protrusion 1512 of the nozzle body 151 is aligned with the notch 1120 of the step portion 112. Then, the nozzle body 151 is pulled out in the direction away from the storage cup 10, so that the injection hole 1012 at the top of the storage cup 10 is exposed. At this time, new atomizing liquid can be replenished into the storage chamber 1041 through the injection hole 1012. After the atomizing liquid is replenished, the nozzle body 151 needs to be reinstalled back into the first housing. When installing the nozzle at the nozzle mounting port 110 of the 11, first insert the lower end of the nozzle body 151 into the nozzle mounting port 110, aligning the limiting protrusion 1512 of the nozzle body 151 with the notch 1120 of the step portion 112. Then, apply force to push the nozzle body 151 in the direction close to the liquid storage cup 10, causing the limiting protrusion 1512 to pass through the notch 1120 of the step portion 112. Next, rotate the nozzle body 151 from the second position to the first position, causing the limiting protrusion 1512 to be misaligned with the notch 1120 of the step portion 112, and the sealing member 152 to close the liquid injection hole 1012, thereby completing the installation of the nozzle body 151 and allowing the atomizing module 1 to continue to be used. Therefore, in the technical solution of this embodiment, the entire disassembly and assembly process of the nozzle assembly 15 is highly operable and very convenient to operate.

[0071] In this embodiment, it should be noted that, in specific implementation, the number of limiting protrusions 1512 and notches 1120 can be one or more, and can be flexibly set according to actual usage needs. This embodiment does not impose specific limitations on this. For example, as shown... Figure 7-8 As shown, there are two of each of the limiting protrusions 1512 and notches 1120, and the two notches 1120 of the step portion 112 are arranged at intervals relative to each other, while the two limiting protrusions 1512 of the suction nozzle body 151 are arranged back to back.

[0072] Further, please refer to Figure 1-6 as well as Figure 8In some optional embodiments of this application, the outer surface of the nozzle body 151 is provided with an exposed first marking groove 1511, and the outer surface of the first housing 11 is provided with a second marking groove 115 adjacent to the nozzle mounting port 110. When the nozzle body 151 is rotated to the second position, the first marking groove 1511 and the second marking groove 115 are aligned. With this configuration, when the user needs to add atomizing liquid to the liquid storage chamber 1041 and needs to disassemble the nozzle assembly 15, during the rotation of the nozzle body 151, when the user observes that the first marking groove 1511 on the nozzle body 151 is aligned with the second marking groove 115, it indicates that the limiting protrusion 1512 of the nozzle body 151 is aligned with the notch 1120 of the step portion 112. This allows the user to clearly know that force can be applied to pull the entire nozzle assembly 15 out of the nozzle mounting port 110 of the first housing 11, thereby improving the user's operational convenience from an aesthetic perspective.

[0073] Further, please refer to Figure 1-8 In some optional embodiments of this application, the outer surface of the first housing 11 is provided with an arrow indicator groove 116 for indicating the rotation direction of the suction nozzle body 151, and the arrow indicator groove 116 is disposed adjacent to the suction nozzle mounting port 110. In this embodiment, the arrow indicator groove 116 can instruct the user to perform corresponding rotation operations on the suction nozzle body 151 according to the arrow direction of the arrow indicator groove 116, so that the user can rotate the entire suction nozzle assembly 15 to a first position or a second position, thereby improving the user's operational convenience from an aesthetic perspective. In specific implementation, the arrow indicator groove 116 can be in the form of a unidirectional arrow or a bidirectional arrow, which can be determined according to actual usage needs, and this embodiment does not impose specific limitations on this. For example, as Figure 1-3 , Figure 5 and Figure 7-8 As shown, the arrow indicator groove 116 is a one-way arrow used to indicate that the nozzle body 151 is rotated to the first position, and the end of the arrow indicator groove 116 away from the arrow end is connected to the second marking groove 115. This setting allows the user to clearly know the locking and unlocking directions of the nozzle body 151. That is, when the user needs to disassemble the nozzle assembly 15, the user can rotate the nozzle body 151 to the second position where the limiting protrusion 1512 and the notch 1120 are aligned in the opposite direction to the arrow direction of the arrow indicator groove 116. When the user needs to reinstall the nozzle assembly 15 after replenishing the atomizing liquid, after inserting the nozzle mounting port 110 into the lower end of the nozzle body 151 and aligning the first marking groove 1511 and the second marking groove 115, the user can rotate the nozzle body 151 to the first position where the limiting protrusion 1512 and the notch 1120 are misaligned in the arrow direction of the arrow indicator groove 116.

[0074] Further, please refer to Figure 3 , Figure 5 and Figure 7-10 In some optional embodiments of this application, a first blocking portion 113 is provided on the side surface of the stepped portion 112 facing the liquid storage cup 10. When the mouthpiece body 151 rotates to the first position, the limiting protrusion 1512 abuts against the first blocking portion 113. With this configuration, when the user needs to reinstall the mouthpiece assembly 15 after replenishing the atomizing liquid, when the mouthpiece body 151 rotates to the position where the limiting protrusion 1512 abuts against the first blocking portion 113, the user can clearly feel that the mouthpiece body 151 is blocked and cannot continue to rotate the mouthpiece body 151 in the locking direction. This allows the user to clearly know that the mouthpiece body 151 has rotated to the first position where the limiting protrusion 1512 is misaligned with the notch 1120, thereby improving the user's operational convenience from a tactile perspective.

[0075] Furthermore, please continue to refer to Figure 3 , Figure 5 and Figure 7-10 In some optional embodiments of this application, a second blocking part 114 protrudes from the side of the step portion 112 facing the liquid storage cup 10. The second blocking part 114 has a blocking surface 1141 that is flush with the inner wall of the notch 1120. When the nozzle body 151 is rotated to the second position, the limiting protrusion 1512 abuts against the blocking surface 1141 of the second blocking part 114. With this configuration, when the user needs to add atomizing liquid to the liquid storage cavity 1041 and needs to disassemble the nozzle assembly 15, during the rotation of the nozzle body 151, when the nozzle body 151 rotates to the position where the limiting protrusion 1512 abuts against the second blocking part 114, the user can clearly feel that the nozzle body 151 is blocked and cannot continue to rotate the nozzle body 151 in the unlocking direction. This allows the user to clearly know that the nozzle body 151 has rotated to the second position where the limiting protrusion 1512 and the notch 1120 are opposite each other, thereby improving the user's operational convenience from a tactile perspective.

[0076] Furthermore, please continue to refer to Figure 3 , Figure 5 and Figure 7-10In some optional embodiments of this application, the stepped portion 112 has an anti-rotation protrusion 119 protruding on the side facing the liquid storage cup 10, and the limiting protrusion 1512 has an anti-rotation groove 15120 adapted to the anti-rotation protrusion 119 on the side surface facing away from the outer peripheral wall of the nozzle body 151. The side surface of the anti-rotation protrusion 119 facing the nozzle body 151 and the groove wall surface of the anti-rotation groove 15120 are both arc surfaces. At least one of the limiting protrusion 1512 and the anti-rotation protrusion 119 is made of plastic. When the nozzle body 151 rotates to the first position, the anti-rotation protrusion 119 engages with the anti-rotation groove 15120. With this configuration, the engagement between the anti-rotation protrusion 119 and the anti-rotation groove 15120 prevents the nozzle body 151 from rotating relative to the first housing 11 after it rotates to the first position, thereby improving the installation stability between the nozzle body 151 and the first housing 11. In this embodiment, it is understood that in some specific application scenarios, since at least one of the limiting protrusion 1512 and the anti-rotation protrusion 119 is made of plastic, and the surface of the anti-rotation protrusion 119 facing the mouthpiece body 151 is an arc surface, when the user applies force to rotate the mouthpiece body 151 from the second position to the first position, when the limiting protrusion 1512 and the anti-rotation protrusion 119 come into contact, the surface of the limiting protrusion 1512 and the anti-rotation protrusion 119 in contact (or the surface of the anti-rotation protrusion 119 and the limiting protrusion 1512 in contact) will undergo a certain degree of elastic deformation, so that the limiting protrusion 1512 and the anti-rotation protrusion 119 can slide relative to each other until the limiting protrusion 1512 abuts against the first blocking part 113. At this time, the part of the anti-rotation protrusion 119 with an arc surface is engaged in the anti-rotation groove 15120. Furthermore, since the side surface of the anti-rotation protrusion 119 facing the nozzle body 151 and the groove wall surface of the anti-rotation groove 15120 are both arc surfaces, when the user forcefully rotates the nozzle body 151 from the first position to the second position, the arc-shaped part of the anti-rotation protrusion 119 can slide out from the anti-rotation groove 15120 and slide relative to the limiting protrusion 1512 until the limiting protrusion 1512 abuts against the second blocking part 114.

[0077] Further, please refer to Figure 3-4 as well as Figure 6In some optional embodiments of this application, the outer peripheral wall of the suction nozzle body 151 is further provided with a shoulder portion 1513 located above the limiting protrusion 1512. The shoulder portion 1513 contacts the side surface of the step portion 112 facing away from the liquid storage cup 10. When the suction nozzle body 151 rotates to the first position, the side surface of the limiting protrusion 1512 facing away from the liquid storage cup 10 contacts the side surface of the step portion 112 facing the liquid storage cup 10. Alternatively, when the suction nozzle body 151 rotates to the first position, there is a gap between the side surface of the limiting protrusion 1512 facing away from the liquid storage cup 10 and the side surface of the step portion 112 facing the liquid storage cup 10, and the size of the gap along the height direction of the first housing 11 is less than 0.1 mm (assuming the gap is D, then 0 < D < 0.1 mm).

[0078] In this embodiment, based on the above structural design, when the nozzle body 151 is in the first position where the limiting protrusion 1512 and the notch 1120 are misaligned, on the one hand, because the shoulder portion 1513 of the nozzle body 151 is in contact with the upper surface of the step portion 112, and on the other hand, because the upper surface of the limiting protrusion 1512 is in contact with the lower surface of the step portion 112 or there is a gap of less than 0.1mm, the nozzle body 151 is difficult to move significantly up and down along the height direction of the first housing 11 when it is in the first position, thereby effectively avoiding the unpleasant experience of the nozzle body 151 giving the user a noticeable feeling of looseness. Moreover, when the nozzle body 151 is in the first position, the shoulder portion 1513 of the nozzle body 151 can cover the step portion 112 of the first housing 11, thereby improving the aesthetic appearance of the nozzle mounting port 110 of the first housing 11.

[0079] Further, please refer to Figure 4 and Figure 6 In some optional embodiments of this application, the top of the liquid storage cup 10 is also provided with an exhaust hole 1013 communicating with the liquid storage chamber 1041. The exhaust hole 1013 is spaced apart from the injection hole 1012, and the sealing member 152 covers the opening of the exhaust hole 1013 to prevent the atomized liquid in the liquid storage chamber 1041 from leaking from the exhaust hole 1013. In this embodiment, during the process of injecting atomized liquid into the liquid storage chamber 1041 through the injection hole 1012, the air in the liquid storage chamber 1041 can be discharged to the outside through the exhaust hole 1013. This effectively reduces the increase in air pressure in the liquid storage chamber 1041 caused by the inability of air in the liquid storage chamber 1041 to be discharged to the outside during the liquid injection process. Consequently, the atomized liquid in the liquid storage chamber 1041 is squeezed by the air pressure and flows out from the position where the liquid storage chamber 1041 communicates with the atomizing core 14 (i.e., Figure 6 The risk of leakage at the inlet hole (1032 shown) is present.

[0080] Further, referring to the figures, in some optional embodiments of this application, the sealing element 152 is an annular structure with a vent hole 1520. The vent hole 1520 of the sealing element 152 is respectively connected to the suction channel 150 of the nozzle body 151 and the atomization channel 1031 of the liquid storage cup 10. This configuration ensures that when the nozzle body 151 is in the first position where the limiting protrusion 1512 and the notch 1120 are misaligned, the sealing element 152 can simultaneously cover the injection hole 1012 and the vent hole 1013 to prevent the atomized liquid in the liquid storage cavity 1041 from leaking from the injection hole 1012 and the vent hole 1013. In specific implementations, the sealing element 152 can be an open-ring structure (such as a "C"-shaped open-ring structure) or a closed-ring structure (such as a circular ring structure), as long as it meets the usage requirements. This embodiment does not impose specific limitations on this.

[0081] Furthermore, in some optional embodiments of this application, the specific structural composition of the liquid storage cup 10 can be as follows:

[0082] Specifically, please refer to Figure 6 as well as Figure 10-11 The liquid storage cup 10 includes a top cover 101 made of a sealing material (such as silicone, rubber, or silicone rubber), a bottom cover 102 made of a sealing material (such as silicone, rubber, or silicone rubber), an air passage 103 having an atomization channel 1031, and a hollow, through-hole cup body 104. The top cover 101 covers the top of the cup body 104, and the bottom cover 102 covers the bottom of the cup body 104. The top cover 101 is provided with a liquid injection hole 1012 and a first mounting through hole 1011 spaced apart from the liquid injection hole 1012 (illustratively, as shown in the figure). Figure 4 and Figure 6As shown, the first mounting hole is located between the injection hole 1012 and the vent hole 1013. The bottom cover 102 is provided with a second mounting through hole 1021. One end of the air passage tube 103 is sealed and fitted into the first mounting through hole 1011, and the other end is sealed and fitted into the second mounting through hole 1021. The top cover 101, bottom cover 102, air passage tube 103, and cup body 104 together enclose the liquid storage chamber 1041. The side wall of the air passage tube 103 is provided with an inlet hole 1032 that communicates with the liquid storage chamber 1041. The atomizing core 14 is installed in the air passage tube 103 and covers the inlet hole 1032. The atomizing liquid in the liquid storage chamber 1041 can be conducted to the mist through the inlet hole 1032. The atomizing core 14 (i.e., the atomizing core 14 can be connected to the liquid storage chamber 1041 through the liquid inlet hole 1032); the top cover 101 has an annular groove 1014 recessed on the side facing away from the bottom cover 102, and the lower end of the mouthpiece body 151 is rotatably fitted in the annular groove 1014 (it can be understood that the cross-section of the part of the mouthpiece body 151 that fits with the annular groove 1014 can be circular, and correspondingly, the annular groove 1014 can be a circular annular groove), the air inlet end of the suction channel 150 is connected to the first mounting through hole 1011, and the sealing member 152 contacts the top cover 101 and simultaneously covers the opening of the liquid injection hole 1012 and the opening of the exhaust hole 1013.

[0083] In this embodiment, the annular groove 1014 positions the lower end of the nozzle body 151, allowing the nozzle body 151 to be more stably held at the nozzle mounting opening 110 of the first housing 11 without easily shaking. Furthermore, it improves the rotational stability of the nozzle body 151 during rotation. In this embodiment, it should be noted that after the lower end of the nozzle body 151 is rotatably fitted into the annular groove 1014, the circumferential wall surface of the lower end of the nozzle body 151 (i.e., the outer or inner circumferential wall surface of the lower end of the nozzle body 151) can contact the top cover 101, generating a certain amount of friction between the nozzle body 151 and the top cover 101, thereby improving the installation and rotational stability of the nozzle body 151.

[0084] Further, please refer to Figure 6 and Figure 11 In some optional embodiments of this application, a liquid storage cotton 105 is provided in the liquid storage cavity 1041. The liquid storage cotton 105 can absorb the atomized liquid in the liquid storage cavity 1041, making it less likely for the atomized liquid in the liquid storage cavity 1041 to leak from the injection hole 1012 and the vent hole 1013. The specific material of the liquid storage cotton 105 can be sponge or fiber cotton.

[0085] Further, please refer to Figure 6In some optional embodiments of this application, the liquid storage cotton 105 is configured to cover the liquid inlet hole 1032 so that the atomizing liquid adsorbed by the liquid storage cotton 105 can be supplied to the atomizing core 14 for heating and atomization in a timely manner, reducing the risk of the atomizing core 14 running dry due to lack of liquid; moreover, there is a gap L between the side surface of the top cover 101 facing the bottom cover 102 (i.e., the lower side surface of the top cover 101) and the side surface of the liquid storage cotton 105 facing the top cover 101 (i.e., the upper side surface of the liquid storage cotton 105). With this configuration, compared to setting the upper side surface of the liquid storage cotton 105 to contact the lower side surface of the top cover 101, the risk of the atomizing liquid overflowing from the liquid inlet hole 1012 or the vent hole 1013 during the process of injecting the atomizing liquid into the liquid storage cavity 1041 through the liquid injection hole 1012 can be reduced because the liquid absorption speed of the liquid storage cotton 105 is slower than the injection speed of the atomizing liquid. In order to better ensure that the atomizing liquid does not overflow from the injection hole 1012 or the vent hole 1013 during the process of injecting atomizing liquid into the liquid storage chamber 1041, the size of the interval L can optionally be 4mm to 12mm, that is, 4mm≤L≤12mm.

[0086] Furthermore, considering that in some specific application scenarios, during the transportation of the atomizing module 1, the liquid storage cotton 105 may shift along the height of the cup 104 due to factors such as bumps during transport, which may result in the liquid storage cotton 105 not completely covering the liquid inlet hole 1032 or even failing to cover it. This could lead to the atomizing coil 14 running dry due to insufficient liquid intake from the liquid storage cotton 105 during subsequent vaping use (when the atomizing coil 14 runs dry, it not only affects the user's vaping experience but may also damage the atomizing coil 14). Based on this consideration, to avoid the problem of the atomizing coil 14 running dry during subsequent vaping use, please refer to... Figure 6 and Figure 11 In some optional embodiments of this application, a stop 1015 protrudes from the side of the top cover 101 facing the bottom cover 102. The stop 1015 is located inside the liquid storage cavity 1041, along the height direction of the cup body 104 (i.e., Figure 6 In the vertical direction of the cup body 104, the end face of the baffle 1015 facing away from the top cover 101 and the side surface of the liquid storage cotton 105 facing the baffle 1015 have a first minimum distance H1, and the wall of the liquid inlet hole 1032 and the side surface of the liquid storage cotton 105 facing the bottom cover 102 have a second minimum distance H2, where H1≤H2. With this setting, even if the liquid storage cotton 105 moves upward along the height direction of the cup body 104 during the transportation of the atomizing module 1, the baffle 1015 will prevent the liquid storage cotton 105 from moving excessively and failing to completely cover the liquid inlet hole 1032. This effectively avoids the problem of dry burning of the atomizing core 14 due to lack of liquid during subsequent suction use.

[0087] Further, please refer to Figure 6 In some optional embodiments of this application, the vertical height of the baffle 1015 along the height direction of the cup body 104 is 4mm to 12mm, and the end face of the baffle 1015 facing away from the top cover 101 abuts against the side surface of the liquid storage cotton 105 facing the baffle 1015. This arrangement not only ensures a sufficient gap between the upper surface of the liquid storage cotton 105 and the lower surface of the top cover 101, but also prevents the liquid storage cotton 105 from shifting along the height direction of the cup body 104. This not only ensures that the atomized liquid does not overflow from the injection hole 1012 or the vent hole 1013 during the liquid injection process, but also effectively avoids the problem of dry burning of the atomizing core 14 due to lack of liquid during subsequent suction use.

[0088] Correspondingly, please refer to Figure 19-21 This application also provides an aerosol generating device, which includes a battery 24, a first control circuit board 16, and an atomizing module 1 as described in any of the above embodiments (e.g., Figure 1-11 As shown, the battery 24 and the first control circuit board 16 are both installed inside the first housing 11. The first control circuit board 16 is electrically connected to the battery 24 and the atomizing core 14 respectively. The battery 24 can supply power to the atomizing core 14 or stop supplying power to the atomizing core 14 through the first control circuit board 16, so as to improve the intelligence of the aerosol generating device.

[0089] In this embodiment, thanks to the improvements to the atomizing module 1 described above, the aerosol generating device provided in this embodiment has the same technical effects as the atomizing module 1 described above, and will not be repeated here. It should be noted that other contents of the aerosol generating device provided in this embodiment can be referred to the relevant contents of the atomizing module 1 embodiment described above, and will not be repeated here.

[0090] Correspondingly, please refer to Figure 12-14 This application also provides an aerosol generating device, which includes a power supply module 2 and an atomizing module 1 as described in any of the above embodiments (e.g., Figure 1-11As shown), the atomizing module 1 also includes a first electrode assembly 12 electrically connected to the atomizing core 14. The first electrode assembly 12 is exposed on the bottom wall or circumferential side wall of the first housing 11 (it can be understood here that the circumferential side wall of the first housing 11 includes the front side wall, rear side wall, left side wall, and right side wall of the first housing 11); the power supply module 2 includes a second housing 21, a battery 24, a second control circuit board 25, and a second electrode assembly 22. The battery 24 and the second control circuit board 25 are both installed inside the second housing 21, and the second electrode assembly 22 is exposed on the second housing 21. The outer wall of the device is connected to the battery 24 and the second electrode assembly 22. The second housing 21 is detachably connected to the first housing 11. The second electrode assembly 22 is in electrical contact with the first electrode assembly 12, thereby realizing the electrical connection between the atomizing module 1 and the power supply module 2. This allows the battery 24 in the power supply module 2 to provide power to the atomizing core 14 in the atomizing module 1. The second control circuit board 25 can control the battery 24 to supply power to the atomizing core 14 or stop supplying power to the atomizing core 14, thereby improving the intelligence of the aerosol generating device.

[0091] In this embodiment, it is understood that when the first electrode assembly 12 is exposed on the bottom wall of the first housing 11, the second electrode assembly 22 is exposed on the top of the second housing 21. In this case, the aerosol generating device has an up-and-down structure where the atomizing module 1 is located above the power supply module 2. When the second electrode assembly 22 is exposed on the circumferential side wall of the second housing 21, the aerosol generating device has a left-right structure where the atomizing module 1 is located to the side of the power supply module 2.

[0092] In this embodiment, it should be noted that, in specific implementation, the second housing 21 can be an integral structure or a split structure assembled from different housing structures. Its specific structural form can be determined according to actual usage needs, and this embodiment does not impose specific limitations on it. Furthermore, in specific implementation, the detachable connection between the second housing 21 and the first housing 11 can be a snap-fit ​​connection, a plug-in connection, a magnetic connection, a threaded connection, etc., as long as it meets the usage requirements; this embodiment does not impose specific limitations on it.

[0093] In this embodiment, thanks to the improvement of the atomizing module 1, the aerosol generating device provided in this embodiment has the same technical effect as the atomizing module 1, which will not be described again here.

[0094] In this embodiment, it should be further noted that, in the aerosol generating device provided in this embodiment, since the first housing 11 of the atomizing module 1 and the second housing 21 of the power supply module 2 are detachably connected, the atomizing module 1 and the power supply module 2 containing the battery 24 can be mutually disassembled and assembled, compared to... Figure 19-21 The embodiment shown here has a non-detachable aerosol generating device for the atomizing module 1, and the aerosol generating device provided in this embodiment (such as...) Figure 12-14 The advantages of this design are twofold. First, when battery 24 is damaged, simply detach power supply module 2 from atomizing module 1 and then assemble a new power supply module 2 onto atomizing module 1, allowing the aerosol generator to continue operating without replacing the entire aerosol generator. This effectively reduces user costs and is more environmentally friendly, as atomizing module 1 can be reused. Second, similarly, when atomizing module 1 is damaged (e.g., atomizing core 14 is damaged), simply detach atomizing module 1 from power supply module 2 and then assemble a new atomizing module 1 onto power supply module 2, allowing the aerosol generator to continue operating without replacing the entire aerosol generator. This again effectively reduces user costs and is more environmentally friendly, as atomizing module 2 can be reused.

[0095] Further, please refer to Figure 12-16 In some optional embodiments of this application, the first housing 11 has a first sidewall 111 along its circumference. The first sidewall 111 is located between the top surface of the first housing 11 and the bottom surface of the first housing 11. The first electrode assembly 12 is exposed on the first sidewall 111. The first electrode assembly 12 includes a first positive electrode 121 and a first negative electrode 122 that are spaced apart.

[0096] The second housing 21 has a second sidewall 211 along its circumference. The second sidewall 211 is located between the top surface of the second housing 21 and the bottom surface of the second housing 21. The second electrode assembly 22 is exposed on the second sidewall 211. The second electrode assembly 22 includes a second positive electrode 221 and a second negative electrode 222 that are spaced apart. The second sidewall 211 is detachably connected to the first sidewall 111, and the second positive electrode 221 is in electrical contact with the first positive electrode 121, and the second negative electrode 222 is in electrical contact with the first negative electrode 122.

[0097] In this embodiment, it should be noted that, in specific implementation, the detachable connection between the first side wall 111 of the first housing 11 and the second side wall 211 of the second housing 21 can be a snap-fit ​​connection, a plug-in connection, a magnetic connection, etc., as long as it can meet the usage requirements. This embodiment does not impose specific restrictions on this. It is understood here that when the detachable connection between the first sidewall 111 of the first housing 11 and the second sidewall 211 of the second housing 21 is a magnetic connection, at least one first magnetic element 13 is fixed on the first sidewall 111 and at least one second magnetic element 23 is fixed on the second sidewall 211. At least one first magnetic element 13 and at least one second magnetic element 23 attract each other. In specific implementation, at least one of the first magnetic element 13 and the second magnetic element 23 is a magnet. For example, both the first magnetic element 13 and the second magnetic element 23 are magnets. Or, for example, one of the first magnetic element 13 and the second magnetic element 23 is a magnet, and the other is a magnetic conductor made of a magnetically conductive material (e.g., iron, nickel-chromium-iron alloy, silicon steel, etc.). As long as the usage requirements are met, it is acceptable. This embodiment does not impose specific restrictions on the structural form of the first magnetic element 13 and the second magnetic element 23.

[0098] In this embodiment, compared to the top-bottom structure where the aerosol generating device is positioned above the power supply module 2, this embodiment designs the aerosol generating device as a left-right structure where the aerosol generating module 1 is positioned to the side of the power supply module 2. This helps to shorten the overall height of the aerosol generating device. In some specific application scenarios, when a user carries the aerosol generating device in their pocket, it makes it less likely for the nozzle body 151 of the aerosol module 1 to be exposed to the outside air. This reduces the risk of the nozzle body 151 being contaminated by dust and other impurities in the outside air due to prolonged exposure to the outside air.

[0099] Further, please refer to Figure 13-16In some optional embodiments of this application, a boss portion 1110 is provided on the first side wall 111 of the first housing 11, and the end face of the first electrode assembly 12 is exposed on the boss portion 1110. A limiting groove 2110 adapted to the boss portion 1110 is provided on the side wall of the second housing 21, and the second electrode assembly 22 is exposed in the limiting groove 2110. The boss portion 1110 is fitted in the limiting groove 2110. This configuration has several advantages. First, by utilizing the interaction between the boss 1110 and the limiting groove 2110, the relative movement between the power supply module 2 and the atomizing module 1 along the vertical or horizontal direction of the aerosol generating device can be better restricted, thereby improving the connection stability between the atomizing module 1 and the power supply module 2. Second, by utilizing the alignment effect between the boss 1110 and the limiting groove 2110, it is easier to assemble the atomizing module 1 and the power supply module 2 together more quickly and accurately. Third, since the first electrode assembly 12 is enclosed by the boss 1110 and the second electrode assembly 22 is hidden in the limiting groove 2110, compared to having the first electrode assembly 12 protrude from the first side wall 111 of the first housing 11 and the second electrode assembly 22 protrude from the second side wall 211 of the second housing 21, it is beneficial to reduce the risk of damage to the first electrode assembly 12 and the second electrode assembly 22 from impacts by external objects during the separate transportation or carrying of the atomizing module 1 and the power supply module 2.

[0100] Furthermore, considering that in certain application scenarios, when the atomizing module 1 is damaged and needs replacement, users may purchase counterfeit atomizing modules 1. Since counterfeit atomizing modules 1 are typically of poor quality, combining them with genuine power supply modules 2 can easily lead to problems such as burnt-out atomizing core 14, burnt-out battery 24, leakage, and poor atomized flavor. This not only severely impacts the user experience but also seriously damages the commercial reputation of the genuine product manufacturer. Therefore, to prevent users from combining counterfeit atomizing modules 1 with genuine power supply modules 2 and experiencing a negative user experience, an anti-counterfeiting design can be implemented for the aerosol generating device, as follows:

[0101] Please refer to Figure 13-16 as well as Figure 18In some optional embodiments of this application, the atomizing module 1 further includes a first control circuit board 16 installed in the first housing 11. The first control circuit board 16 is electrically connected to the atomizing core 14 and the first electrode assembly 12, respectively. The first electrode assembly 12 further includes a first communication electrode 123, which is spaced apart from the first positive electrode 121 and the first negative electrode 122. The second electrode assembly 22 further includes a second communication electrode 223, which is spaced apart from the second positive electrode 221 and the second negative electrode 222, and is in electrical contact with the first communication electrode 123.

[0102] The first control circuit board 16 is configured to send the pre-stored first inspection information to the second control circuit board 25 after the first negative electrode 122 and the second negative electrode 222 are in contact and the first communication electrode 123 is in contact with the second communication electrode 223.

[0103] The second control circuit board 25 is configured to compare the received first verification information with the preset second verification information to determine whether the first verification information and the second verification information match. If they match, it means that the current atomizing module 1 is a genuine product that matches the power supply module 2. At this time, the second control circuit board 25 conducts the electrical connection between the second positive electrode 221 and the battery 24 so that the atomizing core 14 can normally obtain power from the battery 24 and perform atomization. If not, it means that the current atomizing module 1 is a counterfeit product. At this time, the second control circuit board 25 disconnects the electrical connection between the second positive electrode 221 and the battery 24 to prevent the atomizing core 14 from being powered on and causing a poor user experience.

[0104] In this embodiment, it should be noted that, in specific implementation, the form of the first verification information can be at least one of coded information and first circuit parameter information, as long as it can achieve the anti-counterfeiting function of the aerosol generating device. This embodiment does not impose specific restrictions on the specific form of the first verification information. The coded information includes at least one of numbers, letters, and special symbols, and can be used to represent the product model, production date, manufacturer's name, etc.; the first circuit parameter information includes at least one of the impedance value of the atomizing core 14 and the impedance value between the first negative electrode 122 and the first communication electrode 123.

[0105] To improve the anti-counterfeiting performance of the aerosol generating device, the first verification information includes coded information and first circuit parameter information. When the second control circuit board 25 receives the coded information and first circuit parameter information sent by the first control circuit board 16, the second control circuit board 25 first compares the first circuit parameter information with its own pre-stored second circuit parameter information to determine whether the first circuit parameter information and the second circuit parameter information match. If they do not match, it indicates that the current atomizing module 1 is a counterfeit product. At this time, the second control circuit board 25 disconnects the electrical connection between the second positive electrode 221 and the battery 24; if they match... If the first decoded information is matched with the second decoded information, the second control circuit board 25 will then decode the received encoded information and compare it with the second decoded information stored in its own memory to determine whether the first decoded information and the second decoded information match. If they do not match, it means that the current atomizing module 1 is a counterfeit product. At this time, the second control circuit board 25 disconnects the electrical connection between the second positive electrode 221 and the battery 24. If the first decoded information and the second decoded information match, it means that the current atomizing module 1 is genuine. At this time, the second control circuit board 25 connects the electrical connection between the second positive electrode 221 and the battery 24.

[0106] In this embodiment, it should also be noted that, in order to achieve reliable electrical contact between the electrodes in the first electrode assembly 12 and the electrodes in the second electrode assembly 22, the electrodes in the first electrode assembly 12 can be in the form of conductive pins, and the electrodes in the second electrode assembly 22 can be in the form of conductive springs. It is understood that conductive pins are electrodes that do not have a telescopic function, while conductive springs are electrodes that can telescopically extend or retract. The specific structural composition of conductive springs is well known to those skilled in the art and will not be described further here.

[0107] Further, please refer to Figure 6 , Figure 10 , Figure 13 and 18In some optional embodiments of this application, an air intake channel 117 is further provided inside the first housing 11. The air intake end of the air intake channel 117 is connected to the outside (exemplarily, the bottom of the first housing 11 is provided with an air intake hole 118 that is connected to the outside, and the air intake end of the air intake channel 117 is connected to the outside through the air intake hole 118). The air outlet end of the air intake channel 117 is connected to the atomization channel 1031 of the liquid storage cup 10. The atomization module 1 also includes an airflow sensor 17 for detecting the user's suction action at the mouthpiece body 151. The airflow sensor 17 is installed inside the first housing 11 and electrically connected to the first control circuit board 16. The second control circuit board 16 includes a first microcontroller unit 161 and a first switch transistor 162. The first microcontroller unit 161 is electrically connected to the first switch transistor 162, the airflow sensor 17, the atomizing core 14, the first negative electrode 122, and the first communication electrode 123. The first switch transistor 162 is electrically connected to the atomizing core 14 and the first positive electrode 121. The second control circuit board 25 includes a second microcontroller unit 251 and a second switch transistor 252. The second microcontroller unit 251 is electrically connected to the battery 24, the second switch transistor 252, the second negative electrode 222, and the second communication electrode 223. The second switch transistor 252 is electrically connected to the battery 24 and the second positive electrode 221.

[0108] The first microcontroller unit 161 is configured to send the pre-stored first verification information to the second microcontroller unit 251 after the first negative electrode 122 and the second negative electrode 222 are in contact and the first communication electrode 123 and the second communication electrode 223 are in contact; and to control the first switch tube 162 to be turned on when the second positive electrode 221 and the battery 24 are in a conductive state and the suction signal sent by the airflow sensor 17 is received, so that the atomizing core 14 can be powered on and work.

[0109] The second microcontroller unit 251 is configured to compare the received first verification information with the preset second verification information to determine whether the first verification information and the second verification information match. If they do not match, it indicates that the current atomizing module 1 is a counterfeit product. At this time, the second microcontroller unit 251 controls the second switch tube 252 to turn off, thereby disconnecting the second positive electrode 221 from the battery 24 to prevent the atomizing core 14 from being powered on. If they do match, it indicates that the current atomizing module 1 is genuine. At this time, the second microcontroller unit 251 controls the second switch tube 252 to turn on, thereby connecting the second positive electrode 221 to the battery 24 so that the atomizing core 14 can be powered on normally.

[0110] In this embodiment, when the first negative electrode 122 is in contact with the second negative electrode 222 and the first communication electrode 123 is in contact with the second communication electrode 223, the first microcontroller unit 161 is activated due to the connection of the battery 24. After being activated, the first microcontroller unit 161 sends the first verification information to the second microcontroller unit 251 so that the second microcontroller unit 251 can determine whether the current atomizing module 1 is genuine based on the first verification information. When the second microcontroller unit 251 determines that the current atomizing module 1 is genuine, the second microcontroller unit 251 controls the second switching tube 252 to be turned on, so that the atomizing core 14 can be in standby mode. In this case, if the user bites the mouthpiece body 151 at this time... When suction is performed, a suction airflow is formed along the path that connects the air inlet 118, air inlet channel 117, atomization channel 1031, and suction channel 150 in sequence. This suction airflow triggers the airflow sensor 17 to send a suction signal to the first microcontroller unit 161 to indicate that the user is suctioning. When the first microcontroller unit 161 receives the suction signal, it controls the first switch tube 162 to turn on, thereby energizing the atomizing core 14 and atomizing the atomized liquid it adsorbs into an aerosol. When the suction airflow flows through the atomizing core 14, the aerosol generated by the atomizing core 14 is carried away by the suction airflow and finally discharged to the mouthpiece body 151 for the user to inhale. When the user stops inhaling, the airflow disappears, triggering the airflow sensor 17 to send a stop signal to the first microcontroller unit 161, indicating that the user has stopped inhaling. Upon receiving this stop signal, the first microcontroller unit 161 controls the first switch tube 162 to disconnect, thereby de-energizing the atomizing core 14 and stopping its operation. This improves the intelligence level of the aerosol generating device, thus enhancing the user experience.

[0111] In this embodiment, it should be noted that in some specific application scenarios, if the second microcontroller unit 251 of the second control circuit board 25 does not receive the first verification information sent by the first microcontroller unit 161 of the first control circuit board 16 within a preset time period (which can be 2 seconds, 3 seconds, 4 seconds, etc.) after the first negative electrode 122 and the second negative electrode 222 and the first communication electrode 123 and the second communication electrode 223 come into contact, the second microcontroller unit 251 can determine that the current atomizing module 1 is a counterfeit product. It can be understood that after the first negative electrode 122 and the second negative electrode 222 and the first communication electrode 123 and the second communication electrode 223 come into contact, the impedance value between the second negative electrode 222 and the second communication electrode 223 will change (specifically, increase). The second microcontroller unit 251 can then know that the atomizing module 1 and the power supply module 2 have been assembled together, and thus begin the countdown.

[0112] In this embodiment, it should also be noted that, in specific implementation, the first switch 162 and the second switch 252 can be diodes, transistors, metal-oxide-semiconductor field-effect transistors, etc., as long as they can meet the usage requirements. This embodiment does not impose specific restrictions on the types of the first switch 162 and the second switch 252.

[0113] Further, please refer to Figure 13 and Figure 16 In some optional embodiments of this application, the power supply module 2 further includes a charging interface 26 electrically connected to the second control circuit board 25. A through hole 214 communicating with the outside is provided on the outer wall of the second housing 21, corresponding to the charging interface 26 (exemplarily, the through hole 214 is located on the bottom wall of the second housing 21). This arrangement allows the user to easily charge the battery 24 when its power is low or depleted, thereby extending the lifespan of the power supply module 2 and enabling repeated use. In specific implementations, the charging interface 26 can be a USB interface or a Type-C interface; this embodiment does not impose specific limitations on this.

[0114] Further, please refer to Figure 13 and Figure 16-18 In some optional embodiments of this application, the power supply module 2 further includes a display component 27 for displaying visual information. The display component 27 is mounted on any circumferential side wall of the second housing 21 other than the second side wall 211 (such as the front side wall, rear side wall or right side wall of the second housing 21), and the display component 27 is electrically connected to the second control circuit board 25.

[0115] In this embodiment, by adding a display component 27 for displaying visual information on the second housing 21, users can easily and intuitively observe visual information such as the operating parameters of the aerosol generating device. For example, the display component 27 can display visual information such as the remaining power of the battery 24, the operating temperature of the battery 24, the output power of the battery 24, the remaining amount of atomizing liquid in the liquid storage chamber 1041, and preset animation patterns, thus improving the user experience. In addition, in some specific application scenarios, when the second microcontroller unit 251 of the second control circuit board 25 determines that the current atomizing module 1 is a counterfeit product, the second microcontroller unit 251 can also control the display component 27 to display preset prompt information to inform the user that the current atomizing module 1 is incompatible with the power supply module 2 and cannot be used for aspiration.

[0116] In this embodiment, it should be noted that, in specific implementation, the structure of the display component 27 can be a flexible display component that can be bent (such as a flexible OLED screen, a flexible AMOLED screen, a flexible LCD screen, etc.) or a rigid display component 27 that cannot be bent (such as an LED flat panel display screen). It can be determined according to actual usage requirements, and this embodiment does not impose specific restrictions on it.

[0117] In some preferred embodiments, the display component 27 is a flexible display component. The flexible display component is mounted on the second housing 21 circumferentially and covers at least two circumferential sidewalls of the second housing 21, so that the display area of ​​the flexible display component can be distributed on multiple outer sidewalls in different directions along the circumference of the second housing 21, thereby improving the information display range of the power supply module 2, enabling the power supply module 2 to realize multi-directional information display, and displaying more visual information to users.

[0118] Further, please refer to Figure 16-17 In some optional embodiments of this application, the circumferential sidewall of the second housing 21 is provided with a mounting groove 213 for mounting a flexible display component. Two positioning protrusions 212 protrude from the groove wall of the mounting groove 213, spaced apart relative to each other along the height direction of the second housing 21. A positioning hole 270, matching the positioning protrusion 212, is provided on the upper and lower edges of the flexible display component. The flexible display component can be fixed in the mounting groove 213 by adhesive bonding, simultaneously covering the front, right, and rear sidewalls of the second housing 21. Furthermore, the corresponding positioning protrusion 212 extends into the corresponding positioning hole 270. In this embodiment, the positioning protrusions 212 and positioning holes 270 can position the flexible display component during installation in the mounting groove 213, preventing significant movement of the flexible display component along the height and circumferential direction of the first housing 11. This facilitates the quick and neat installation of the flexible display component into the mounting groove 213 of the second housing 21.

[0119] Further, please refer to Figure 12-17 In some optional embodiments of this application, the power supply module 2 further includes a protective shell 28 made of a light-transmitting material (such as glass, acrylic, etc.), which is mounted on the second housing 21 and covers the display component 27.

[0120] In this embodiment, the protective shell 28 not only ensures that the user can observe the visual information displayed by the display component 27 through the protective shell 28, but also protects the display component 27 from damage caused by impacts from external objects. In addition, it also avoids the display component 27 being exposed, which would affect the overall aesthetic appearance of the aerosol generating device.

[0121] It should be noted that other details of the atomizing module 1, power supply module 2, and aerosol generating device disclosed in this application can be found in the prior art, and will not be repeated here.

[0122] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural transformations made based on the concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
