After a period of use, the aerosol matrix in the cotton of the atomizing core is already saturated. When the replenishment container is removed and reassembled to the replenishment interface, the increased negative pressure inside the liquid storage chamber will cause the aerosol matrix adsorbed in the cotton to be squeezed out, which can easily cause leakage.

[0031] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.
[0032] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).
[0033] The aerosol generating device provided in this application has a separate liquid replenishment container from the liquid storage chamber in its initial state. Users can configure the liquid replenishment container, containing the desired aerosol matrix, according to their needs, and assemble it into the liquid replenishment interface of the liquid storage chamber to supply the aerosol matrix. The atomizing core assembly heats and atomizes the aerosol matrix in the liquid storage chamber to generate aerosols of the corresponding flavor. When the container interface of the liquid replenishment container is threaded into the liquid replenishment interface of the liquid storage chamber, a one-way snap-fit engagement is formed using a first snap-fit structure and a second snap-fit structure, making the liquid replenishment container impossible to disassemble after connection. This prevents leakage of the aerosol matrix under negative pressure caused by repeated assembly and disassembly of the liquid replenishment container.
[0034] The following describes some embodiments of the aerosol generating apparatus and aerosol generating equipment provided in this application, with reference to the accompanying drawings.
[0035] An embodiment of the first aspect of this application provides an aerosol generating apparatus 100, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the aerosol generating device 100 includes a housing 1, an atomizing core assembly 2, and a replenishment container 3. A liquid storage chamber 11 is provided inside the housing 1, and the atomizing core assembly 2 is disposed within the liquid storage chamber 11 to heat and atomize the aerosol matrix within the liquid storage chamber 11 to generate aerosols. A replenishment interface 12 is provided on the outside of the liquid storage chamber 11, and the replenishment container 3 has a container interface 31. The container interface 31 is adapted to the replenishment interface 12 and can be connected and assembled with the replenishment interface 12 via a threaded connection, so that the aerosol matrix contained in the replenishment container 3 can flow into the liquid storage chamber 11 through the replenishment interface 12 to replenish the liquid storage chamber 11 with aerosol matrix. The container interface 31 is provided with a first snap-fit structure 311, and the replenishment interface 12 is provided with a second snap-fit structure 121. The first snap-fit structure 311 and the second snap-fit structure 121 form a one-way rotational engagement along the screw tightening direction of the container interface 31. That is, when the container interface 31 is tightened relative to the replenishment interface 12, the first snap-fit structure 311 can rotate relative to the second snap-fit structure 121; and when the container interface 31 is loosened (i.e., rotated in the opposite direction), the first snap-fit structure 311 can be snapped and fixed with the second snap-fit structure 121, thereby preventing the container interface 31 from rotating, thus achieving the anti-disassembly effect of the replenishment container 3.
[0036] The rotation direction of the thread of the container interface 31 relative to the liquid replenishment interface 12 can be set according to usage requirements. The snap-fit direction of the first snap-fit structure 311 and the second snap-fit structure 121 is adapted to the rotation direction of the thread of the container interface 31. For example, when the container interface 31 rotates clockwise relative to the liquid replenishment interface 12 to the tightening direction, the first snap-fit structure 311 and the second snap-fit structure 121 form a snap-fit fixation in the counterclockwise direction of the container interface 31. Conversely, when the container interface 31 rotates counterclockwise relative to the liquid replenishment interface 12 to the tightening direction, the first snap-fit structure 311 and the second snap-fit structure 121 form a snap-fit fixation in the clockwise direction.
[0037] It is understandable that in common aerosol generating devices, the atomizing core assembly has an adsorption structure (such as cotton wrapping) for adsorbing the aerosol matrix. After a period of use, the adsorption structure is basically saturated, and the adsorbed aerosol matrix is easily squeezed out under pressure. At this time, if the assembled replenishment container 3 is disassembled and reassembled, a negative pressure will be generated in the liquid storage chamber, which can easily cause the aerosol matrix to be squeezed out and leakage to occur.
[0038] The aerosol generating device 100 in this embodiment has been improved and optimized in structure. It can form a one-way threaded connection between the container interface 31 of the replenishment container 3 and the replenishment interface 12 of the liquid storage tank 11. The replenishment container 3 is difficult to disassemble after assembly and connection, thereby preventing leakage caused by repeated assembly and disassembly of the replenishment container 3 during use.
[0039] It should be noted that, in the initial state, the liquid replenishment container 3 and the liquid storage tank 11 of the aerosol generating device 100 in this embodiment can be separate structures. Users can select the liquid replenishment container 3 with the desired aerosol matrix flavor and assemble it themselves. Correspondingly, the housing 1 of the aerosol generating device 100 adopts a structure that is easy to disassemble, so as to facilitate user assembly. Of course, the aerosol generating device 100 in this embodiment can also be designed to be pre-assembled at the factory, and different aerosol generating devices 100 can be formed according to the different aerosol matrices contained in the liquid replenishment container 3 for users to choose from.
[0040] In further embodiments of this application, such as Figure 4 , Figure 5 and Figure 6 As shown, on the replenishment container 3, the container interface 31 has a tubular structure. The first snap-fit structure 311 specifically includes first snap teeth 3111 arranged circumferentially along the container interface 31, and the first snap teeth 3111 are all inclined towards the direction of thread loosening of the container interface 31. For example... Figure 7As shown in the diagram, the first locking teeth 3111 are all inclined in the counterclockwise direction along the container interface 31, that is, the outer surface of the first locking teeth 3111 in the radial direction is a bevel or arc surface, and the tail of the first locking teeth 3111 in the counterclockwise direction has an end face; correspondingly, the second locking structure 121 is arranged in the circumferential direction of the container interface 31 to correspond to the first locking teeth 3111. When the container interface 31 rotates clockwise (tightening), the outer surface of the first locking tooth 3111 in the radial direction contacts the second locking structure 121, and the inclined design of the outer surface can generate a guiding effect, so that the first locking tooth 3111 can rotate with the container interface 31 relative to the second locking structure 121; when the container interface 31 rotates counterclockwise (loosening), the end face of the first locking tooth 3111 in the circumferential direction can abut against the second locking structure 121, so that the second locking structure 121 blocks the first locking tooth 3111, thereby preventing the first locking tooth 3111 and the container interface 31 from continuing to rotate (i.e., cannot be loosened).
[0041] It should be noted that the number of the first locking teeth 3111 and the second locking structure 121 can both be one or more, and the specific number and tilt angle can be set according to the specific dimensions of the container interface 31 and the liquid replenishment interface 12 and the assembly requirements; preferably, such as Figure 7 In the example, a plurality of first locking teeth 3111 are uniformly arranged in the circumferential direction of the container interface 31, and a plurality of second locking structures 121 are uniformly arranged in the circumferential direction of the liquid replenishment interface 12.
[0042] Furthermore, in a specific implementation, such as Figure 5 , Figure 7 In the example shown, the second snap-fit structure 121 is inclined towards the thread tightening direction of the container interface 31, and the inclination angle matches the inclination angle of the first snap-fit tooth 3111 in the thread loosening direction, so that the end face of the second snap-fit structure 121 in the thread tightening direction is opposite to the end face of the first snap-fit tooth 3111 in the thread loosening direction in the circumferential direction. When the container interface 31 is loosened, the end face of the first snap-fit tooth 3111 abuts against the end face of the second snap-fit structure 121, so that the first snap-fit tooth 3111 and the second snap-fit structure 121 form a snap-fit fixation, preventing the container interface 31 from loosening.
[0043] Furthermore, in a specific implementation, such as Figure 5 and Figure 7 In the example shown, the second snap-fit structure 121 includes an elastic plate structure 1211. The elastic plate structure 1211 has a certain elasticity in the thickness direction (as shown in the radial direction of the container interface 31 in the figure), and can generate a certain elastic deformation under pressure, but it is difficult to generate large elastic deformation in the length and width directions. Figure 7In the example, when the replenishing container 3 rotates along the tightening direction of the thread, the container interface 31 drives the first locking tooth 3111 to rotate clockwise. When the outer side of the first locking tooth 3111 contacts the side wall of the elastic plate structure 1211, it can generate radial pressure on the elastic plate, so that the elastic plate can undergo elastic deformation in the radial direction, so that the first locking tooth 3111 can rotate normally. When the replenishing container 3 rotates along the loosening direction of the thread, the end face of the first locking tooth 3111 in the loosening direction abuts against the end face of the elastic plate structure 1211 in the tightening direction. Since the elastic plate structure 1211 is difficult to generate large elastic deformation in the length direction, it can form an abutment block against the first locking tooth 3111, so that the container interface 31 and the replenishing container 3 are difficult to continue to rotate in the loosening direction, thus achieving the effect of preventing disassembly.
[0044] It should be noted that in practical applications, by designing the length, width, thickness and tilt angle of the elastic plate structure 1211 and selecting appropriate materials, the elastic plate structure 1211 can only produce a certain elastic deformation in the lateral direction, and it is difficult to produce large elastic deformation in the length and width directions, so as to meet the unidirectional blocking requirements of the first locking tooth 3111.
[0045] Furthermore, in one specific implementation, the first locking tooth 3111 has a groove on its end face in the loosening direction of the thread. The groove is adapted to the second locking structure 121. When the first locking tooth 3111 rotates with the container interface 31 in the loosening direction until it abuts against the second locking structure 121, a portion of the second locking structure 121 can extend into the groove and form an insert-type locking engagement with the first caliper. This further prevents relative sliding of the second locking structure 121 when it abuts against the end face of the first locking tooth 3111, thereby improving the stability of the locking state. When the first locking tooth 3111 rotates with the container interface 31 in the tightening direction of the thread, the second locking structure 121 and the groove of the first locking tooth 3111 can naturally separate, without affecting the tightening operation of the container interface 31.
[0046] In further embodiments of this application, such as Figure 7In the example, the inner diameter of the replenishment port 12 is larger than the outer diameter of the container port 31. During assembly, the container port 31 extends into the replenishment port 12 to form a plug-in fit. The outer wall of the container port 31 is provided with a corresponding external thread 3112 and a first snap-fit structure 311. Correspondingly, the inner wall of the replenishment port 12 is provided with a corresponding internal thread and a second snap-fit structure 121. The external thread 3112 of the container port 31 and the internal thread of the replenishment port 12 form a threaded fit. When the container port 31 rotates in the direction of thread tightening, the first snap-fit structure 311 can rotate relative to the second snap-fit structure 121. When the container port 31 rotates in the direction of thread loosening, the second snap-fit structure 121 and the first snap-fit structure 311 form a snap-fit fixation, thus blocking the first snap-fit structure 311 and the container port 31, keeping the container port 31 and the replenishment port 12 in a threaded connection state.
[0047] It should be noted that, since the thread size in the radial direction of the container interface 31 is smaller than that of the first snap-fit structure 311, in order to facilitate the threaded connection with the liquid replenishment interface 12 and prevent the first snap-fit structure 311 from interfering with the threaded connection, a method such as... Figure 6 The configuration is such that the first snap-fit structure 311 is positioned above the external thread 3112 on the container interface 31; correspondingly, the second snap-fit structure 121 in the liquid replenishment interface 12 is positioned above the internal thread.
[0048] In practical applications, the dimensions of the container interface 31 and the replenishment interface 12 can be designed according to usage requirements. For example, the outer diameter of the replenishment interface 12 can be set to be smaller than the inner diameter of the container interface 31. During assembly, the replenishment interface 12 can be inserted into the container interface 31. The container interface 31 has an internal thread and a first snap-fit structure 311 on its inner sidewall, and the replenishment interface 12 has a corresponding external thread and a second snap-fit structure 121 on its outer sidewall. This allows the container interface 31 and the replenishment interface 12 to form a threaded connection. When the container interface 31 rotates in the direction of thread tightening, the first snap-fit structure 311 can rotate relative to the second snap-fit structure 121. When the container interface 31 rotates in the direction of thread loosening, the second snap-fit structure 121 and the first snap-fit structure 311 form a snap-fit fixation, thereby blocking the first snap-fit structure 311 and the container interface 31, so that the container interface 31 and the replenishment interface 12 remain in a threaded connection state.
[0049] It should be noted that, since the thread size of the container interface 31 is smaller than that of the first snap-fit structure 311 in the radial direction, in order to facilitate the threaded connection with the liquid replenishment interface 12 and prevent the first snap-fit structure 311 from interfering with the threaded connection, the first snap-fit structure 311 can be set below the internal thread on the container interface 31; correspondingly, the second snap-fit structure 121 in the liquid replenishment interface 12 is set below the external thread 3112.
[0050] In further embodiments of this application, such as Figure 2 and Figure 5 In the example shown, the contact surface between the replenishment port 12 and the container port 31 is provided with an interface seal 123 to seal the gap between them, thereby preventing leakage of the aerosol matrix in the replenishment container 3 during the replenishment process from the replenishment port 12 into the storage tank 11. The interface seal 123 can be, for example, […]. Figure 2 The sealing sleeve shown can also be a sealing ring or other sealing form; the interface seal 123 can be set inside the container interface 31 or outside the container interface 31, depending on the specific cooperation between the container interface 31 and the replenishment interface 12.
[0051] In further embodiments of this application, such as Figure 2 and Figure 5 As shown, the replenishment port 12 has a conduit structure 122, which is arranged along the height direction. After the container port 31 and the replenishment port 12 are assembled, the conduit structure 122 extends into the container port 31, and the conduit structure 122 is sealed to the inner wall of the container port 31. Figure 2 The state shown allows the aerosol matrix in the replenishment container 3 to flow directly into the conduit structure 122, and then into the storage tank 11 through the inlet channel 1122. By providing the conduit structure 122 that extends into the container interface 31, a sealing configuration can be easily achieved, for example... Figure 2 In the example, a corresponding interface seal 123 can be provided on the outer wall of the conduit structure 122 to form a sealing fit with the inner wall of the container interface 31. Compared with the method of providing a sealing structure on the end face of the container interface 31, the method of setting in this embodiment has a larger sealing coverage area and a better sealing effect.
[0052] In further embodiments of this application, such as Figure 2 and Figure 8As shown, a sealing element 312 is provided inside the container interface 31 of the replenishment container 3. In the initial state, the sealing element 312 seals the container interface 31 to prevent leakage of the aerosol matrix inside the replenishment container 3 during assembly. Correspondingly, a desealing structure 124 adapted to the sealing element 312 is provided inside the replenishment interface 12. When the container interface 31 and the replenishment interface 12 are connected and assembled, the desealing structure 124 can puncture the sealing element 312 inside the container interface 31 to make the container interface 31 and the replenishment interface 12 connected. Then, the aerosol matrix inside the replenishment container 3 can flow into the storage tank 11 through the replenishment interface 12. Under normal circumstances, the replenishment container 3 needs to be inverted and connected to the replenishment port 12 to allow the aerosol matrix to flow into the replenishment port 12 using gravity. Therefore, a punctureable sealing membrane 312 is provided inside the container port 31 to prevent leakage during the connection process between the container port 31 and the replenishment port 12. After the two are connected and assembled, the sealing membrane 312 is punctured, allowing the aerosol matrix to flow into the storage tank 11 through the replenishment port 12. The sealing membrane 312 can be a flexible membrane for easy puncture; the unsealing structure 124 can be as follows: Figure 8 The protruding structure shown can be, for example, a conical cylindrical structure provided on the end face of the conduit structure 122, or a conical or rod-shaped structure, which can facilitate piercing the sealing membrane 312.
[0053] In further embodiments of this application, such as Figure 2 and Figure 9In the example, the liquid storage chamber 11 of the aerosol generating device 100 includes a chamber shell 111 and a chamber base 112. The top of the chamber shell 111 has a suction nozzle structure 13, and the side wall of the chamber shell 111 has a laterally protruding boss structure 1111. The chamber base 112 is assembled and connected to the bottom of the chamber shell 111 to cover the bottom of the chamber shell 111 (including the bottom of the boss structure 1111), so that a chamber capable of storing the aerosol matrix is formed inside the liquid storage chamber 11; the atomizing core assembly 2 is disposed in the chamber of the liquid storage chamber 11 that contains the aerosol matrix. The boss structure 1111 has a first through hole 1112 extending along the height direction, and a second snap-fit structure 121 is provided on the inner side wall of the first through hole 1112; an interface groove 1121 is provided on the tank base 112 at a position corresponding to the first through hole 1112, and a threaded sleeve 1123 with internal threads is connected in the interface groove 1121. The tank base 112 has a liquid inlet channel 1122 that connects the interface groove 1121 and the inside of the liquid storage tank 11, and a liquid replenishment interface 12 is formed through the first through hole 1112, the interface groove 1121 and the threaded sleeve 1123. When the container interface 31 of the replenishment container 3 passes through the first through hole 1112 and extends into the threaded sleeve 1123 of the interface groove 1121, rotating the replenishment container 3 allows the external thread 3112 on the container interface 31 to form a threaded connection with the threaded sleeve 1123. During the tightening process, the first locking structure 311 on the outer wall of the container interface 31 moves to the height of the second locking structure 121 in the first through hole 1112, thereby enabling the first locking structure 311 and the second locking structure 121 to form a one-way rotational engagement. That is, when the container interface 31 is tightened, the first locking structure 311 can rotate relative to the second locking structure 121, and when the container interface 31 is loosened, the second locking structure 121 locks and fixes the first locking structure 311.
[0054] An embodiment of the second aspect of this application provides an aerosol generating device 400, such as... Figure 2 , Figure 9 and Figure 10As shown, the aerosol generating device 400 includes the aerosol generating apparatus 100 and the power supply component 420 as described in any of the embodiments of the first aspect. The power supply component 420 is connected to the aerosol generating apparatus 100 and electrically connected to the atomizing core assembly 2 of the aerosol generating apparatus 100 to supply power to the atomizing core assembly 2, so that the atomizing core assembly 2 can heat up when energized, thereby heating and atomizing the aerosol matrix to generate aerosol. The liquid replenishment container 3 of the aerosol generating apparatus 100 is threadedly connected to the liquid replenishment interface 12 of the liquid storage tank 11 via the container interface 31. After assembly, the liquid replenishment container 3 is circumferentially locked by the second locking structure 121 of the liquid replenishment interface 12 and the first locking structure 311 of the container interface 31, preventing the liquid replenishment container 3 from being loosened by unscrewing and thus achieving an anti-disassembly effect.
[0055] In practical applications, the power supply component 420 can be installed inside the housing 1 of the aerosol generating device 100, or the power supply component 420 can be installed with an independent housing structure as needed, and the power supply component can be installed outside the aerosol generating device 100. It can be assembled with the aerosol generating device 100 through a corresponding connection method to form the complete aerosol generating equipment 400.
[0056] The following describes a specific example of the aerosol generating apparatus 400 of this application with reference to the accompanying drawings.
[0057] like Figures 1 to 10 As shown, the aerosol generating device 400 is specifically a device with an external replenishment container 3, including a housing 1, an atomizing core assembly 2, a replenishment container 3, and a power supply assembly 420. The housing 1 has a split structure and can be assembled and connected to be installed on the outside of the liquid storage chamber 11, the replenishment container 3, and the power supply assembly 420. In the height direction, the top of the liquid storage chamber 11 has a suction nozzle structure 13, which extends out of the housing 1, and the suction nozzle structure 13 has an air passage structure 14 extending in the height direction. The bottom of the liquid storage chamber 11 is provided with a corresponding electrical connection piece 1125 and a first magnetic suction member 1124. The power supply assembly 420 is located below the liquid storage chamber 11. The power supply assembly 420 has a battery mounting base, in which a battery 421 and an electronic control board 422 are installed. On the side of the battery mounting base facing the bottom of the liquid storage chamber 11, a corresponding electrode 423 and a second magnetic suction member 424 are provided. The second magnetic member 424 of the power supply component 420 is attracted and connected to the corresponding first magnetic member 1124 so that the power supply component 420 and the liquid storage tank 11 are connected and assembled, and the liquid storage tank 11 and the power supply component 420 are wrapped and fixed together by the housing 1; the battery 421 is electrically connected to the electronic control board 422, and the electrode 423 abuts against the electrical connection piece 1125 of the liquid storage tank 11.
[0058] like Figure 2In the example, the portion of the base 112 of the liquid storage chamber 11 that extends into the housing 111 is provided with a tubular structure extending along the height direction to form an atomizing chamber 1126. The top of the atomizing chamber 1126 is sealed by an upper seal 113 and communicates with the nozzle structure 13 through an air passage structure 14. The bottom of the atomizing chamber 1126 is sealed by a lower seal 114. The atomizing core assembly 2 is disposed in the atomizing chamber 1126 and includes a first liquid suction member 22 and an atomizing core 21. The first liquid suction member 22 is a cylindrical structure. The atomizing core 21 is connected to the inner wall of the first liquid suction member 22. The atomizing core 21 is connected to the electrical connection piece 1125 at the bottom of the liquid storage chamber 11 through a pin structure, and then forms an electrical connection with the power supply assembly 420 through the electrical connection piece 1125 and the electrode 423. A liquid inlet hole is provided on the side wall of the atomizing chamber 1126 so that the aerosol matrix inside the liquid storage chamber 11 can contact the first liquid suction member 22, thereby adsorbing the aerosol matrix onto the surface of the atomizing core 21 for heating and atomization. The side of the liquid storage chamber 11 has a boss structure 1111 with a first through hole 1112. The first through hole 1112 communicates with the interface groove 1121 at the corresponding position on the chamber base 112. The bottom of the interface groove 1121 has a conduit structure 122. An interface seal 123 is sleeved on the outer side wall of the conduit structure 122. A threaded sleeve 1123 is also provided in the interface groove 1121, thereby forming a liquid replenishment interface 12. Correspondingly, the chamber base 112 also has a liquid inlet channel 1122. One end of the liquid inlet channel 1122 communicates with the conduit structure 122, and the other end extends into the liquid storage chamber 11. After the replenishment container 3 is connected and assembled with the replenishment interface 12 through the container interface 31, the aerosol matrix contained in the replenishment container 3 can enter the liquid inlet channel 1122 under the action of gravity, and then flow into the liquid storage tank 11, forming a replenishment operation for the liquid storage tank 11.
[0059] Specifically, the bottom of the replenishment container 3 has a tubular container interface 31. The outer wall of the container interface 31 is provided with a first snap-fit structure 311 and an external thread 3112, with the external thread 3112 located below the first snap-fit structure 311. Correspondingly, the inner wall of the first through hole 1112 of the replenishment interface 12 is provided with a second snap-fit structure 121, and the inner wall of the threaded sleeve 1123 of the replenishment interface 12 has an internal thread. When the container interface 31 extends into the threaded sleeve 1123 of the replenishment interface 12, rotating the replenishment container 3 allows the external thread 3112 of the container interface 31 to form a threaded connection with the internal thread of the threaded sleeve 1123. The first locking structure 311 includes a plurality of first locking teeth 3111 evenly arranged circumferentially, and the plurality of first locking teeth 3111 are inclined in the direction of thread loosening; the second locking structure 121 includes a plurality of elastic plate structures 1211 evenly arranged circumferentially, the plurality of elastic plate structures 1211 are inclined in the direction of thread tightening, and correspond one-to-one with the first locking teeth 3111. When the replenishment container 3 is tightened, the radially outer surface of the first locking teeth 3111 can form radial compression on the elastic plate structure 1211, so that the elastic plate structure 1211 produces a certain elastic deformation, so that the first locking teeth 3111 can rotate normally; when the replenishment container 3 is loosened, the end face of the first locking teeth 3111 in the direction of thread loosening abuts against the end face of the elastic plate structure 1211 in the direction of thread tightening, thereby forming a one-way locking fixation to prevent the replenishment container 3 from being loosened.
[0060] In one specific example, a groove can be provided on the end face of the first locking tooth 3111 in the thread loosening direction, so that when the liquid replenishment container 3 is loosened, the elastic plate structure 1211 can extend into the groove of the first locking tooth 3111, which can further improve the locking stability between the first locking tooth 3111 and the elastic plate structure 1211.
[0061] Additionally, in a specific example, for instance Figure 8 In the example, a sealing film 312 can be provided inside the replenishment port 12, and a corresponding unsealing structure 124 can be provided on the top of the conduit structure 122 of the replenishment port 12, so that the container port 31 of the replenishment container 3 is kept closed before the replenishment container 3 is in the replenishment port 12 state; when the container port 31 is assembled with the replenishment port 12, the conduit structure 122 of the replenishment port 12 extends into the container port 31, and the sealing film 312 is punctured by the unsealing structure 124 during the tightening of the container port 31, so that the container port 31 and the conduit structure 122 of the replenishment port 12 are connected, so as to prevent leakage during the assembly operation.
[0062] The aerosol generating device 400 in this embodiment can form a threaded connection and a one-way snap-fit with the container interface 31 of the replenishment container 3 and the replenishment interface 12 of the liquid storage tank 11. After the replenishment container 3 and the replenishment interface 12 are assembled and connected, they are difficult to disassemble, thereby preventing leakage caused by repeated assembly and disassembly of the replenishment container 3 during use.
[0063] Furthermore, the aerosol generating device 400 in this embodiment also has all the beneficial effects of the aerosol generating device 100 in any of the above embodiments, which will not be repeated here.
[0064] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
