Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and in particular to a pump module and an aerosol generation device including the pump module. Background Technology

[0002] An aerosol generating device is a device capable of atomizing a liquid matrix to generate aerosols. An exemplary aerosol generating device exists, comprising an atomizing component for atomizing the liquid matrix, a pumping component having a pump chamber, and a supply tank for storing the liquid matrix. The pumping component drives the supply tank to replenish the liquid matrix to the atomizing component. The atomizing component is connected to the pump chamber via a first hose, and the supply tank is connected to the pump chamber via a second hose. Therefore, during the assembly of the atomizing component, pumping component, and supply tank, the first hose needs to connect the atomizing component and the pumping component, and the second hose needs to connect the supply tank and the pumping component. This not only results in an excessive number of components in the aerosol generating device, complicating the assembly process, but also hinders the removal and reuse of the pumping component.

[0067] Please refer to Figure 1 This application provides an aerosol generating device 100, which includes a first fluid source and a pump module 2. The pump module 2 has a pump chamber 211 capable of storing fluid. The pump module 2 can be connected to the first fluid source, thereby allowing fluid to be transferred between the pump chamber 211 and the first fluid source. Typically, the first fluid source includes an atomizing module 1, which has a first storage cavity 11 capable of storing fluid. When the first fluid source 1 is connected to the pump module 2, a fluid channel can be formed between the first storage cavity 11 and the pump chamber 211, allowing the pump chamber 211 to inject fluid into the first storage cavity 11 or receive fluid from the first storage cavity 11. Thus, when the fluid channel is open, fluid can flow between the first storage cavity 11 and the pump chamber 211. The fluid is a flowable substance; for example, the fluid may include a liquid or, for example, a gas.

[0068] It should be noted that the ability of a storage chamber or pump chamber to store fluid means that the fluid can be maintained in the storage chamber or pump chamber for a long time or a short time. Maintaining the fluid in the storage chamber or pump chamber includes the fluid being able to remain statically in the storage chamber or pump chamber, or the fluid flowing in the storage chamber or pump chamber, or the fluid flowing along the storage chamber or pump chamber. Therefore, the storage chamber or pump chamber may include a cavity or may include a pipe.

[0069] In some embodiments, the aerosol generating device 100 further includes a second fluid source, to which the pump module 2 can be connected, thereby enabling fluid to be transferred between the pump chamber 211 and the second fluid source. Typically, the second fluid source includes a liquid storage module 32, which has a second storage cavity 31 capable of storing fluid. When the liquid storage module 3 is connected to the pump module 2, a fluid channel can be formed between the second storage cavity 31 and the pump chamber 211, allowing the pump chamber 211 to inject fluid into the second storage cavity 31 or receive fluid from the second storage cavity 31. Thus, when the fluid channel is open, fluid can flow between the second storage cavity 31 and the pump chamber 211.

[0070] In some embodiments, the pump module 2 further includes a pump body 21 and a movable component 23, wherein a pump chamber 211 is disposed within the pump body 21, and the movable component 23 is configured to decrease or increase the air pressure in the pump chamber 211 during operation. As an example, the pump chamber 211 is configured to draw fluid from either the first storage chamber 11 or the second storage chamber 31 when the movable component 23 is in operation. As an example, the pump chamber 211 is configured to direct fluid into either the first storage chamber 11 or the second storage chamber 31 when the movable component 23 is in operation. As an example, the pump chamber 211 is configured to draw fluid from one of the first storage chamber 11 and the second storage chamber 31 and introduce at least a portion of the drawn fluid into the other when the movable component 23 is in operation. As an example, the pump chamber 211 is configured to inject fluid into the second storage chamber 31 to increase the air pressure in the second storage chamber 31 when the movable component 23 is in operation, thereby causing the second storage chamber 31 to automatically inject fluid into the first storage chamber 11.

[0071] In some embodiments, the pump module 2 further includes a first housing 22 disposed around the pump body 21, a first through hole 241 disposed on the first housing 22, a second through hole 242 disposed on the first housing 22, a first channel 251 for connecting the first through hole 241 and the pump chamber 211, and a second channel 252 for connecting the second through hole 242 and the pump chamber. The first through hole 241 is used to introduce or export fluid into the pump chamber 211 through the first channel 251. The second through hole 242 is used to introduce or export fluid into the pump chamber 211 through the second channel 252.

[0072] The first housing 22 can be used to shield and protect the pump body 23. The first housing 22 can be directly connected to the atomizing module 1 and / or the liquid storage module 3. Since the first through hole 241 and the second through hole 242 are provided on the first housing 22, when the first housing 22 is connected to the atomizing module 1 and / or the liquid storage module 3, the first storage cavity 11 can be connected to the first channel 251 or the second storage cavity 31 can be connected to the second channel 252.

[0073] At least a portion of the first channel 251 may be disposed in the wall of the first housing 22, or at least a portion of the first channel 251 may be disposed between the first housing 22 and the pump body 23. At least a portion of the second channel 252 may be disposed in the wall of the first housing 22, or at least a portion of the second channel 252 may be disposed between the first housing 22 and the pump body 23.

[0074] In some embodiments, the movable component 23 is configured to decrease the air pressure of the pump chamber 211 during operation so that the pump chamber 211 draws fluid from the first fluid source through the first through-hole 241, or increase the air pressure of the pump chamber 211 so that the pump chamber 211 injects at least a portion of the fluid it draws into the second fluid source through the second through-hole 242.

[0075] Typically, the pump chamber 211 can draw gas from the first storage chamber 11 through the first through-hole 241 and introduce at least a portion of the drawn gas into the second storage chamber 31 through the second through-hole 242 when the movable component 23 is in operation.

[0076] Alternatively, the pump chamber 211 can draw liquid matrix from the second storage chamber 31 through the first through hole 241 and introduce at least a portion of the drawn liquid matrix into the first storage chamber 11 through the second through hole 242 when the movable component 23 is in operation.

[0077] In some embodiments, a first fluid path connecting the atomizing module 1 and the liquid storage module 3 and a second fluid path connecting the atomizing module 1 and the liquid storage module 3 are established inside the first housing 22, and the first and second fluid paths are isolated from each other. As an example, a movable component 23 is disposed in the first fluid path to drive the fluid in the atomizing module 1 to flow towards the liquid storage module 3 along the first fluid path. For instance, when the movable component 23 is in operation, the pump chamber 211 can draw gas from the first storage chamber 11 through the first fluid path, and then at least a portion of the drawn gas is guided to the second storage chamber 31 through the remaining first fluid path, while the liquid matrix in the second storage chamber 31 can flow towards the first storage chamber 11 through the second fluid path. As an example, the movable component 23 is disposed in the second fluid path to drive the fluid in the liquid storage module 3 to flow towards the atomizing module 1 along the second fluid path. For example, when the movable component 23 is running, the pump chamber 211 can draw liquid matrix from the second storage chamber 31 through the second fluid path, and then guide at least a portion of the drawn liquid matrix to the first storage chamber 11 through the remaining second fluid path. The gas in the first storage chamber 11 can flow to the second storage chamber 31 through the first fluid path.

[0078] In some embodiments, reference may be made to Figure 2 The atomizing module 1 includes a second housing 12 and an atomizing core 15 for atomizing a liquid matrix to generate an aerosol, and a first storage cavity 11 is disposed in the second housing 12.

[0079] In some embodiments, the atomizing core 15 includes a liquid-absorbing element and a heating element, wherein the liquid-absorbing element is used to guide the liquid matrix to the heating element, thereby enabling at least a portion of the liquid matrix in the liquid-absorbing element to atomize and generate an aerosol under the heat released by the heating element.

[0080] The liquid-absorbing element may include a porous body. The porous body can be a fiber, such as cotton fiber, polypropylene fiber, polyester fiber, or nylon fiber. The porous body can also be porous ceramic or porous metal; this application does not limit the structure and composition of the porous body.

[0081] In some embodiments, the atomizing core 15 includes an ultrasonic element capable of generating ultrasonic waves, which enables the atomizing core 15 to atomize a liquid matrix into an aerosol. Of course, the atomizing core 15 may also include other elements capable of atomizing a liquid matrix into an aerosol, such as a nozzle capable of turning the liquid matrix into a mist.

[0082] In some embodiments, the atomizing module 1 further includes a liquid storage element (not shown), which has a large number of pores and is capable of adsorbing a large amount of liquid matrix. The liquid storage element is disposed in the first storage cavity 11, and at least partially of the liquid matrix stored in the first storage cavity 11 is retained in the liquid storage element, thereby preventing the liquid matrix from leaking out of the first storage cavity 11. The liquid storage element includes, but is not limited to, one of the following materials: cotton fiber, polypropylene fiber, polyester fiber, nylon fiber, porous ceramic material, polymer fiber, or various combinations of the above materials.

[0083] In some embodiments, the atomizing module 1 further includes an outlet tube 16 for discharging the aerosol. Figure 2 In the illustrated embodiment, the outlet tube 16 extends longitudinally in the second housing 12, and at least a portion of the outlet tube 16 is located in the first storage cavity 11.

[0084] In some embodiments, at least a portion of the atomizing core 15 is disposed in the outlet tube 16. In other embodiments, the atomizing module 1 further includes a compartment (not shown) in which the atomizing core 15 is disposed. The compartment is in communication with the first storage chamber 11 via a liquid channel, allowing the liquid matrix in the first storage chamber 11 to be transferred to the atomizing core 15. The compartment is in fluid communication with the outlet tube 16, allowing the aerosol formed in the compartment to be exported by the outlet tube 16.

[0085] In some embodiments, reference may be made to Figure 3 The wall of the outlet tube 16 is provided with a liquid guiding hole 161 that connects the first storage cavity 11 and the atomizing core 15. The liquid guiding hole 161 can guide the liquid matrix in the first storage cavity 11 to the atomizing core 15 so that the atomizing core 15 can atomize and generate aerosol.

[0086] In some embodiments, the atomizing module 1 further includes a liquid guiding element 17, which is disposed inside the outlet tube 16 and located outside the atomizing core 15. The liquid guiding element 17 can adsorb the liquid matrix stored in the first storage cavity 11 through the liquid guiding hole 161, and can conduct at least a portion of the adsorbed liquid matrix to the atomizing core 15, thereby allowing the liquid matrix to be adsorbed and atomized by the atomizing core 15 to generate an aerosol. By providing the liquid guiding element 17 between the liquid guiding hole 161 and the atomizing core 15, leakage of the liquid matrix stored in the first storage cavity from the outlet tube 16 and the atomizing core 15 can be prevented, and leakage or oil splattering problems caused by excessive wetting of the atomizing core 15 by the liquid matrix can be prevented.

[0087] In some embodiments, reference may be made to Figure 2 The aerosol generating device 100 also includes a mouthpiece 4 having an air outlet 41, an outlet tube 16 connecting to the air outlet 41 of the mouthpiece 4, at least a portion of the mouthpiece 4 being held in the mouth by a user, and the mouthpiece 4 being used to introduce aerosol into the user's oral cavity.

[0088] Furthermore, the atomizing module 1 includes a nozzle 4, or the nozzle 4 of the aerosol generating device 100 is disposed on the atomizing module 1. Even further, the nozzle 4 is integrally formed with the second housing 12, or the nozzle 4 is assembled onto the second housing 12.

[0089] In some embodiments, the pump module 2 further includes a first valve 261 for sealing the first through-hole 241. It is understood that the first valve 261, in its initial state, is capable of sealing the first through-hole 241 to prevent fluid from flowing into or out of the pump chamber 211, so that the pump module 2 can be stored separately.

[0090] In some embodiments, the first valve 261 includes a first inner sealing portion 2611 for sealing the first through hole 241. The first inner sealing portion 2611 is configured to be displaceable or deformable inward to open the first through hole 241, so that the first channel 251 communicates with the first fluid source through the first through hole 241.

[0091] Furthermore, when the atomizing module 1 is connected to the pump module 2, at least a portion of the first valve 261 deforms or shifts in a direction away from the atomizing module 1, thereby opening the first through hole 241 and connecting the first storage cavity 11 and the first channel 251.

[0092] In some embodiments, a first valve 261 is disposed on the first housing 22. Further, see... Figure 3 and Figure 8 The first valve 261 is at least partially disposed in the wall of the first housing 22. This reduces the space occupied by the first valve 261 between the atomizing module 1 and the pump module 2 when the atomizing module 1 is connected to the pump module 2, and helps to ensure that the outer wall of the second housing 12 is in close contact with the outer wall of the first housing 22.

[0093] In some embodiments, reference may be made to Figure 3The first housing 22 includes a first base 221 and a first cover 222. The first through hole 241 includes a first inner hole 2411 formed on the first base 221 and a first outer hole 2412 formed on the first cover 222. At least a portion of the first valve 261 is disposed between the first cover 222 and the first base 221, thereby at least a portion of the first valve 261 is disposed in the wall of the first housing 22. Disposing at least a portion of the first valve 261 between the first cover 222 and the first base 221 can, on the one hand, prevent the first valve 261 from being removed from the first housing 22, and on the other hand, can cover at least a portion of the first valve 261, giving the first housing 22 a more aesthetically pleasing appearance. When the atomizing module 1 is connected to the pump module 2, the outer wall of the first cover 222 can interfere with the second housing 12 to form a sealing ring around the outer end of the first through hole 241 or the first outer hole 2412 between the first housing 22 and the second housing 12, so as to prevent fluid from leaking between the first housing 22 and the second housing 12 through the first through hole 241.

[0094] In some embodiments, the first valve 261 is configured to seal the first outer hole 2412 when in an initial state. Typically, the first valve 261 seals the first outer hole 2412 when the atomizing module 1 is not connected to the pump module 2. Further, a first inner seal 2611 is disposed between the first cover 222 and the first base 221, and the first inner seal 2611 seals the first outer hole 2412 when the first valve 261 is in an initial state.

[0095] The first inner hole 2411 can always remain in communication with the first channel 251, so that part of the fluid in the first channel 251 can flow into the first inner hole 2411 to the interval between the first cover 222 and the first base 221, or flow through the first inner hole 2411 to the contact valve 261. Of course, the first valve 261 can also seal the first inner hole 2411 to isolate the interval between the first cover 222 and the first base 221 from the first channel.

[0096] In some embodiments, the projection of the first outer hole 2412 intersects or coincides with the projection of the first inner hole 2411. The first outer hole 2412 and the first inner hole 2411 may share a central axis.

[0097] In some embodiments, reference may be made to Figure 7 and Figure 8The first valve 261 includes a first abutment portion 2612 connected to the first inner sealing portion 2611. The first abutment portion 2612 is configured to protrude from the first outer hole 2412 when the first valve 261 is in its initial state, thus being located outside the first cover 222 or at least partially within the first outer hole 2412. When abutted by the atomizing module 1, the first abutment portion 2612 displaces toward the first base 221, causing the first inner sealing portion 2611 to open the first outer hole 2412. Further, when abutted by the atomizing module 1, the outer end of the first abutment portion 2612 is flush with the outer wall of the first cover 222.

[0098] In some embodiments, the atomizing module 1 further includes a fifth valve 131. A fifth through-hole 141 is provided on the second housing 12 to allow fluid to flow into or out of the first storage chamber 11. The fifth valve 131 is disposed on the second housing 12 to seal the fifth through-hole 141. It is understood that, in its initial state, the fifth valve 131 can seal the fifth through-hole 141 to prevent fluid from flowing into or out of the first storage chamber 11, allowing the atomizing module 1 to be stored separately.

[0099] Furthermore, when the atomizing module 1 is connected to the pump module 2, the fifth valve 131 and the first valve 261 abut against each other, causing at least a portion of the fifth valve 131 and at least a portion of the first valve 261 to deform or displace in opposite directions. This allows the fifth through hole 141 and the first through hole 241 to open simultaneously, connecting the first storage cavity 11 and the first channel 251. Moreover, the outer wall of the second housing 12 can be tightly fitted to the outer wall of the first housing 22, which not only prevents fluid leakage between the second housing 12 and the first housing 22 but also makes the aerosol generating device 100 more compact, thus helping to reduce the size of the aerosol generating device 100.

[0100] In some embodiments, reference may be made to Figure 1 and Figure 3 The fifth valve 131 is at least partially disposed within the wall of the second housing 12. This helps to reduce the space occupied by the fifth valve 131 between the atomizing module 1 and the pump module 2 when they are connected, and helps to ensure that the outer wall of the second housing 12 is in close contact with the outer wall of the first housing 22. Furthermore, the fifth valve 131 is disposed outside the first storage cavity 11, so that the fifth valve 131 does not occupy the space of the first storage cavity 11, and therefore does not affect the capacity of the first storage cavity 11.

[0101] In some embodiments, reference may be made to Figures 4-6The second housing 12 includes a second base 121 and a second cover 122 for tightly fitting against the first housing 22. The fifth through hole 141 includes a second inner hole 1411 formed on the second base 121 and a second outer hole 1412 formed on the second cover 122. At least a portion of the fifth valve 131 is disposed between the second cover 122 and the second base 121, thereby at least a portion of the fifth valve 131 is disposed in the wall of the second housing 12. Disposing at least a portion of the fifth valve 12 between the second cover 122 and the second base 121 can, on the one hand, prevent the fifth valve 131 from being removed from the second housing 12, and on the other hand, can cover at least a portion of the fifth valve 131, giving the second housing 12 a more aesthetically pleasing appearance, and also allowing the fifth valve 131 to be spaced from the first storage cavity 11. When the atomizing module 1 is connected to the pump module 2, the outer wall of the second cover 122 can interfere with the first housing 22 to form a sealing ring around the outer end of the second through hole 242 or the second outer hole 1412 between the first housing 22 and the second housing 12, so as to prevent fluid from leaking between the first housing 22 and the second housing 12 through the second through hole 242.

[0102] Furthermore, one can refer to Figure 4 and Figure 5 When the atomizing module 1 and the pump module 2 are not connected, the fifth valve 131 seals the second outer hole 1412. The second inner hole 1411 can always remain in communication with the first storage cavity 11. Of course, the fifth valve 131 can also seal the second inner hole 1411 to isolate the area between the second cover 122 and the second base 121 from the first storage cavity 11.

[0103] In some embodiments, at least a portion of the fifth valve 131 deforms or displaces in a direction away from the pump module 2 upon contact with the pump module 2. The projection of the second outer hole 1412 may intersect or coincide with the projection of the second inner hole 1411. The second outer hole 1412 and the second inner hole 1411 may share a common central axis.

[0104] In some embodiments, reference may be made to Figure 5 The inner wall of the second substrate 121 defines at least a portion of the boundary of the first storage cavity 11. This helps to reduce the volume of the atomizing module 1 without changing the capacity of the first storage cavity 11.

[0105] In some embodiments, reference may be made to Figure 5 and Figure 6 The second housing 12 includes a second sidewall 123 and other sidewalls 124. The outer wall of the second sidewall 123 is used for connection with the pump module 2. At least a portion of the fifth valve 131 is disposed in the wall of the second sidewall 123. Alternatively, the second sidewall 123 includes the second base 121 and the second cover 122.

[0106] If the thickness D1 of the second sidewall 123 is too small, the strength of the second sidewall 123 will be insufficient, and the second sidewall 123 may easily break during the process of at least partially placing the fifth valve 131 in the wall of the second sidewall 123. If the thickness D1 of the second sidewall 123 is too large, the volume of the atomizing module 1 will be increased, which is not conducive to miniaturizing the aerosol generating device 100 without changing the capacity of the first storage cavity 11.

[0107] In some embodiments of this application, the thickness D1 of the second sidewall 123 satisfies: 2mm ≤ D1 ≤ 4mm. For example, D1 can be approximately equal to 3mm.

[0108] In some embodiments of this application, the relationship between the thickness D1 of the second sidewall 123 and the thickness D2 of the other sidewall 124 satisfies: D2<D1≤2*D2.

[0109] It should be noted that the thickness D1 of the second sidewall 123 is mainly the average thickness of the portion of the second sidewall 123 corresponding to the portion of the first storage cavity 11. The thickness D2 of the other sidewalls 124 is mainly the average thickness of the portions of the other sidewalls 124 corresponding to the portions of the first storage cavity 11.

[0110] In some embodiments, reference may be made to Figures 4-6 The fifth valve 131 includes a fifth inner sealing portion 1311 for sealing the second outer bore 1412 and a fifth abutment portion 1312 connected to the fifth inner sealing portion 1311; the fifth inner sealing portion 1311 is disposed between the second cover 122 and the second base 121. The fifth abutment portion 1312 is configured to protrude from the second outer bore 1412 when the fifth valve 131 is in its initial state, thereby being located outside the second cover 122, or at least partially located in the second outer bore 1412, and when abutted by the pump module 2, to displace toward the second base 121 and drive the fifth inner sealing portion 1311 to open the second outer bore 1412.

[0111] Furthermore, the fifth contact part 1312 is used to contact the first valve 261 and is contacted by the first valve 261.

[0112] In some embodiments, a second blocking portion 125 is provided between the second base 121 and the second cover 122. When the fifth abutting portion 1312 is abutted, causing the fifth inner sealing portion 1311 to deform or displace, the second blocking portion 125 can prevent the fifth inner sealing portion 1311 from sealing the second inner hole 1411. This allows the second inner hole 1411 to communicate with the outside (e.g., with the first through hole 241) through the second outer hole 1412 when the second outer hole 1412 is open, and the second outer hole 1412 to communicate with the first storage cavity 11 through the second inner hole 1411. Further, the fifth inner sealing portion 1311 is disposed between the second outer hole 1412 and the second blocking portion 125, and when the fifth valve 131 is in its initial state, the fifth inner sealing portion 1311 isolates the second outer hole 1412 from the second inner hole 1411. The first abutting portion 2612 is used to abut against the fifth abutting portion 1312 and is abutted by the fifth abutting portion 1312.

[0113] In some embodiments, the atomizing module 1 and the pump module 2 are detachably connected, and when the two are separated, the fifth valve 131 can automatically reset to reseal the fifth through hole 141, and the first valve 261 can also automatically reset to reseal the first through hole 241.

[0114] Furthermore, one can refer to Figure 6 The fifth valve 131 also includes a fifth elastic part 1313 connected to the fifth inner seal 1311. The fifth elastic part 1313 is configured to deform when the fifth valve 131 is abutted. When the atomizing module 1 is separated from the pump module 2, the fifth elastic part 1313 provides elastic force to drive the fifth inner seal 1311 to reset so that the fifth inner seal 1311 re-seals the second outer hole 1412.

[0115] In some embodiments, a first blocking portion 224 is provided between the first base 221 and the first cover 222. When the first abutting portion 2612 is abutted, causing the first inner sealing portion 2611 to deform or displace, the first blocking portion 224 can prevent the first inner sealing portion 2611 from sealing the first inner hole 2411. This allows the first inner hole 2411 to communicate with the outside (e.g., with the fifth through hole 141) through the first outer hole 2412 when the first outer hole 2412 is open, and the first outer hole 2412 to communicate with the pump chamber 211 through the first inner hole 2411. Further, the first inner sealing portion 2611 is disposed between the first outer hole 2412 and the first blocking portion 224, and when the first valve 261 is in the initial state, the first inner sealing portion 2611 isolates the first outer hole 2412 from the first inner hole 2411.

[0116] In some embodiments, reference may be made to Figure 8The first valve 261 also includes a first elastic portion 2613, which is configured to provide resistance to the inward displacement of the first inner seal portion 2611, thereby helping the first inner seal portion 2611 to maintain sealing of the first through hole 241 before being abutted, and also helping to drive the first inner seal portion 2611 to automatically replicate to reseal the first through hole 241 after the abutting force is removed.

[0117] In some embodiments, reference may be made to Figure 3 and 4 The second cover 122 includes a resilient second outer sealing portion 1221. At least a portion of the second outer hole 1412 is formed on the second outer sealing portion 1221. When the second cover 122 is tightly attached to the first cover 222, the second outer sealing portion 1221 elastically abuts against the first cover 222, thereby providing a seal between the second cover 122 and the first cover 222, which helps prevent fluid leakage from between the second cover 122 and the first cover 222. Simultaneously, during the connection of the atomizing module 1 and the pump module 2, the impact between the atomizing module 1 and the pump module 2 can also be reduced.

[0118] In some embodiments, reference may be made to Figure 7 and Figure 8 The first cover 222 includes a first outer sealing portion 2221 with elasticity. At least a portion of the first outer hole 2412 is formed on the first outer sealing portion 2221. When the second cover 122 is tightly attached to the first cover 222, the first outer sealing portion 2221 elastically abuts against the second cover 122.

[0119] In some embodiments, the second cover 122 includes a second outer sealing portion 1221 with elasticity, and the first cover 222 includes a first outer sealing portion 2221 with elasticity. The second outer sealing portion 1221 has a second sealing groove 1A surrounding the second outer hole 1412, and the first outer sealing portion 2221 has a second sealing rib 2A surrounding the first outer hole 2412. When the second cover 122 is tightly attached to the first cover 222, the second sealing rib 2A is embedded in the second sealing groove 1A, and along the direction in which the second cover 122 is tightly attached to the first cover 222, the second sealing rib 2A elastically abuts against the second outer sealing portion 1221. Since the second sealing rib 2A is embedded in the second sealing groove 1A, when the second sealing rib 2A elastically abuts against the bottom of the second sealing groove 1A, the second sealing rib 2A undergoes elastic deformation, causing the second sealing rib 2A to elastically press against the two side walls of the second sealing groove 1A respectively. This results in a seal between the second sealing rib 2A and the bottom of the second sealing groove 1A, and between the second sealing rib 2A and the groove walls on both sides of the second sealing groove 1A, thereby improving the sealing effect between the second cover 122 and the first cover 222 by at least 3 times.

[0120] Preferably, the distance between the groove walls on both sides of the second sealing groove 1A is at least 10% greater than the width of the second sealing rib 2A, or the distance between the groove walls on both sides of the second sealing groove 1A is at least 0.05 mm greater than the width of the second sealing rib 2A. More preferably, the distance between the groove walls on both sides of the second sealing rib 2A is at least 0.1 mm greater than the width of the second sealing rib 2A. This facilitates the entry of the second sealing rib 2A into the second sealing groove 1A.

[0121] Preferably, the difference between the spacing between the groove walls on both sides of the second sealing groove 1A and the width of the second sealing rib 2A is less than or equal to 0.3 mm. More preferably, the difference between the spacing between the groove walls on both sides of the second sealing groove 1A and the width of the second sealing rib 2A is less than or equal to 0.2 mm. This ensures that after the second sealing groove 1A deforms, the second sealing rib 2A can compress the groove walls on both sides of the second sealing groove 1A, thereby forming a seal between the second sealing rib 2A and the groove walls on both sides of the second sealing groove 1A.

[0122] In some embodiments, reference may be made to Figure 4 and Figure 6 The second sidewall 123 has a second plane 1231 and a second groove 1232 recessed relative to the second plane 1231. The second cover 122 is disposed in the second groove 1232, and the outer wall of the second cover 122 is substantially flush with the second plane 1231. Further, the first housing 22 includes a first sidewall 223, which has a first plane 2231 and a first groove 2232 recessed relative to the first plane 2231. The first cover 222 is disposed in the first groove 2232, and the outer wall of the first cover 222 is substantially flush with the first plane 2231. Therefore, when the second cover 122 is in close contact with the first cover 222, the second plane 1231 can also be in contact with the first plane 2231. Alternatively, the atomizing module 1 and the pump module 2 are arranged laterally, and when the second cover 122 and the first cover 222 are in close contact, there is a very small or no lateral gap between the second plane 1231 and the first plane 2231. This allows the atomizing module 1 and the pump module 2 to be connected very compactly.

[0123] Preferably, when the atomizing module 1 is connected to the pump module 2, the second plane 1231 and the first plane 2231 are arranged face to face and in close contact.

[0124] The first sidewall 223 may include a first base 221 and a first cover 222.

[0125] In some embodiments, reference may be made to Figure 6 The second sidewall 123 also has a third groove 1233 that is further recessed relative to the second groove 1232, and the fifth inner sealing part 1311 is located in the third groove 1233.

[0126] In such Figure 6 In the embodiment shown, the fifth valve 131 includes a fifth annular base 1314, one end of the fifth elastic part 1313 is connected to the inner wall of the fifth annular base 1314, and the other end is connected to the fifth inner sealing part 1311.

[0127] Furthermore, the fifth annular base 1314 is interference-fitted into the third groove 1233, which not only forms a seal between the fifth annular base 1314 and the wall of the third groove 1233, but also fixes the fifth valve 131 in the third groove 1233. Multiple fifth elastic portions 1313 may be present. The fifth elastic portions 1313 may extend non-linearly between the fifth annular base 123 and the fifth inner sealing portion 1311.

[0128] Furthermore, the fifth annular base 1314 of the fifth valve 131 can be fixedly connected to the second cover 122 by means of bonding, welding, snap-fit ​​connection or threaded connection. Thus, during assembly, the second cover 122 and the fifth valve 131 can be assembled as an integral structure with the second base 121.

[0129] In some embodiments, the second cover 122 includes a second support member 1222, and a second outer sealing portion 1221 is disposed on the second support member 1222 and located on the side opposite to the first storage cavity 11. It is understood that the hardness of the support member is greater than the hardness of the sealing member. The support member may include an injection-molded product or a metal product. The sealing member may include a silicone product or a rubber product.

[0130] In some embodiments, reference may be made to Figure 8 The first sidewall 223 also has a fourth groove 2233 that is further recessed relative to the first groove 2232, and the first inner sealing part 2611 is located in the fourth groove 2233.

[0131] In such Figure 8 In the illustrated embodiment, the first valve 261 includes a first annular base 2614, one end of a first elastic portion 2613 is connected to the inner wall of the first annular base 2614, and the other end is connected to a first inner sealing portion 2611. Multiple first elastic portions 2613 may be present. The first elastic portion 2613 may extend non-linearly between the first annular base 2614 and the first inner sealing portion 2611.

[0132] Furthermore, the first annular base 2614 is interference-fitted into the fourth groove 2233, which not only forms a seal between the first annular base 2614 and the wall of the fourth groove 2233, but also fixes the first valve 261 in the fourth groove 2233.

[0133] Furthermore, the first annular base 2614 of the first valve 261 can be fixedly connected to the first cover 222 by means of bonding, welding, snap-fit ​​connection or threaded connection. Thus, during assembly, the first cover 222 and the first valve 261 can be assembled as an integral structure with the first base 221.

[0134] In some embodiments, the first cover 222 includes a first support member, and the first outer sealing portion 222 is disposed on the first support member and located on the side opposite to the pump chamber 211.

[0135] In some embodiments, reference may be made to Figure 1 The pump module 2 further includes a second valve 262 disposed between the first channel 251 and the pump chamber 211. The second valve 262 is configured to open when the air pressure in the pump chamber 211 is lower than the air pressure in the first channel 251, thereby connecting the first channel 251 and the pump chamber 211. Preferably, the second valve 262 has the same structural features as the first valve 261.

[0136] In some embodiments, the movable component 23 is configured to move at least partially within the pumpable chamber 211 during operation.

[0137] As an example, you can refer to Figure 1 The movable component 23 includes a piston 231 movable within the pump chamber 211. As the pump chamber 211 moves, the piston 231 can compress or expand. When the pump chamber 211 expands, the air pressure decreases; when it compresses, the air pressure increases. Further, the movable component 23 is configured to move between a first position and a second position, and the pump chamber 211 compresses to reduce its capacity when the movable component 23 moves from the first position to the second position, and expands to increase its capacity when the movable component 23 moves from the second position to the first position. Even further, the movable component 23 is configured to move longitudinally between the first and second positions.

[0138] In some embodiments, one side of the movable component 23 is connected to the first channel 251, and the other side is connected to the second channel 252. Thus, when the movable component 23 is in operation, the pump module 2 draws fluid from the first fluid source into the pump chamber 211 through the first through-hole 241, and draws at least a portion of the fluid from the pump chamber 211 and discharges it to the second fluid source through the second through-hole 242. Furthermore, the first channel 251 and the second channel 252 are selectively connected through a flow path that at least partially passes through the movable component 23.

[0139] As an example, you can refer to Figure 2The movable component 23 also includes a third connecting member 232 connected to the piston 231. Fluid can pass through the interior of the third connecting member 232. One side of the third connecting member 232 is connected to the first channel 251 through the pump chamber 211, and the other side of the third connecting member 232 is connected to the second channel 252, so that the first channel 251 and the pump chamber 211 can be connected to the second channel 252 through the third connecting member 232.

[0140] In some embodiments, the movable component 23 further includes an open hole 233 communicating with the second channel 252, the open hole 233 being selectively communicating with the pump chamber 211. Alternatively, the movable component 23 further includes an open hole 233 communicating with the pump chamber 211, the open hole 233 being selectively communicating with the second channel 252.

[0141] As an example, the third connecting member 232 has an opening 233 on its side wall. When the movable component 23 is in the first position, the opening 233 is isolated from the pump chamber 211, causing the pump chamber 211 to be disconnected from the second channel 252. When the movable component 23 is in the second position, the opening 233 connects to the pump chamber 211, allowing the pump chamber 211 to connect to the second channel 252 through the opening 233.

[0142] Furthermore, one can refer to Figure 2 The pump module 2 also includes a sealing tube 27, and a third connecting member 232 is movable along the sealing tube 27. When the movable component 23 is in the first position, the open hole 233 is located inside the sealing tube 27. When the movable component 23 is in the second position, there is a gap between the piston 231 and the sealing tube 27 connecting the pump chamber 211 and the open hole 233, or the open hole 233 is located in the pump chamber 211. When the open hole 233 is located inside the sealing tube 27, the inner wall of the sealing tube 27 can be tightly fitted against the open hole 233 to seal it. Alternatively, when the movable component 23 is in the first position, the piston 231 and the sealing tube 27 form a sealed connection, isolating the interior of the sealing tube 27 from the pump chamber 211.

[0143] As an example, you can refer to Figure 1 The piston 231 has an open hole 233, and the piston 231 is also provided with a one-way valve 234 for sealing the open hole 233. The one-way valve 234 is configured to open when the movable component 23 moves from the first position to the second position, so that the open hole 233 communicates with the second channel 252, or so that the second channel 252 communicates with the pump chamber 211 through the open hole 233, so that the fluid in the pump chamber 211 can flow through the piston 231 to the second channel 252. When the movable component 23 moves from the second position to the first position, the valve 234 closes, so that the open hole 233 is isolated from the second channel 252, or so that the second channel 252 is isolated from the pump chamber 211.

[0144] In some embodiments, reference may be made to Figure 2 The third connecting member 232 connects to the piston 231. In some embodiments, reference may be made to... Figure 2 The pump module 2 also includes an operating member 28 for driving the movable component 23, the operating member 28 being configured to be operable to drive the movable component 23 to move. Further, the pump module 2 also includes a reset member 29, which acts on the operating member 28 or the movable component 23 to automatically reset the movable component 23 to a first position. Even further, the operating member 28 is configured to be pressed longitudinally by a user, thereby causing the movable component 23 to move from the first position to a second position.

[0145] In some embodiments, the operating element 28 is connected to the third connecting element 232.

[0146] In some embodiments, reference may be made to Figure 2 and Figure 12 The pump module 2 also includes a first connecting member 201 disposed between the second through hole 242 and the movable component 23. The second channel 252 is partially disposed in the first connecting member 201, so that when the movable component 23 is running, fluid can be introduced into or exported from the pump chamber 211 through the first connecting member 201.

[0147] Furthermore, at least a portion of the first connecting member 201 is deformable or movable. Even further, at least a portion of the first connecting member 201 is deformable or movable as the movable component 23 moves. Still further, the first connecting member 201 is connected to the movable component 23. Connecting the first connecting member 201 to the movable component 23, rather than connecting it to the pump body 21, helps to achieve better consistency in the sidewalls of the pump body 21 and also helps to achieve a smaller volume of the pump body 21 while allowing the second channel 252 to have a larger flow cross-sectional area, thereby helping to reduce the volume of the pump module 2. In some embodiments, at least a portion of the first connecting member 201 is deformable or movable under the drive of the operating member 28. Furthermore, the first connecting member 201 is connected to the operating member 28.

[0148] In some embodiments, reference may be made to Figure 2 The first connecting member 201 includes a deformable hose, one end of which is directly connected to the movable component 23 or indirectly connected to the movable component 23 via an operating member 28. The hose is deformable as the movable component 23 moves, for example, the movable component 23 stretches, contracts, or changes its curvature. The hose can be made of rubber, silicone, or plastic. The other end of the hose can be connected to the base 225 of the pump module 2 or the second through hole 242.

[0149] Alternatives can be found by referring to Figure 12The first connecting member 201 includes a rigid tube directly connected to the movable component 23 or indirectly connected via the operating member 28, or at least a portion of the first connecting member 201 is made of a rigid material, so that the rigid tube or rigid first connecting member 201 can maintain its inherent shape when the movable component 23 moves, thereby preventing the internal channel of the rigid tube or rigid first connecting member 201 from narrowing, twisting, or becoming blocked. For example, the rigid tube or rigid first connecting member 201 is a metal tube, preferably made of stainless steel or copper, preferably low-lead brass.

[0150] Furthermore, one can refer to Figure 12 and Figure 13 The pump module 2 also includes a rigid second connecting member 202. A rigid pipe or a rigid first connecting member 201 is nested with the second connecting member 202, and the first connecting member 201 is linked with the movable component 23, so that the first connecting member 201 can move relative to the second connecting member 202 when the movable component 23 is running. The second connecting member 202 can remain stationary when the movable component 23 is moving.

[0151] Furthermore, the second connecting member 202 is connected to the base 225 of the pump module 2 or the second through hole 242, thereby giving the second through hole 242 a relatively stable position. When the pump module 2 is connected to the liquid storage module 3, the base 225 of the pump module 2 or the second through hole 242 can remain stationary relative to the liquid storage module 3, which helps to prevent fluid leakage between the pump module 2 and the liquid storage module 3.

[0152] The second channel 252 may be partially disposed in the second connecting member 202, so that the second connecting member 202 can connect the first connecting member 201 and the second through hole 242.

[0153] In such Figure 2 and Figure 12 In the embodiment shown, the third connecting member 232 connects the piston 231 and the first connecting member 201, and the third connecting member 232 is connected to the first connecting member 201 through the operating member 28. The operating member 28 can be configured to simultaneously drive the movable 231 and the first connecting member 201 to move when operated.

[0154] In some embodiments, reference may be made to Figures 12-15 The pump module 2 also includes an annular seal 203 connecting the first connector 201 and the second connector 202. The annular seal 203 is used to provide a seal between the first connector 201 and the second connector 202 to prevent fluid in the second channel 252 from leaking between the first connector 201 and the second connector 202.

[0155] Furthermore, a retaining groove for holding the annular seal 203 is provided on one of the first connecting member 201 and the second connecting member 202, so that the annular seal 203 is held on one and can move relative to the other when the movable component 23 or the first connecting member 201 moves.

[0156] In some embodiments, reference may be made to Figure 12 and Figure 14 The pump module 2 also includes a stop 204, and an annular seal 203 is disposed around the periphery of the first connecting member 201 and closely abuts the outer wall of the first connecting member 201. A retaining groove is provided on the second connecting member 202, with its first end open to allow the annular seal 203 to enter. The boundary of the retaining groove has a supporting wall for supporting the annular seal. At least a portion of the annular seal 203 is disposed between the supporting wall and the stop 204, and the stop 204 is disposed adjacent to the first end of the retaining groove to prevent the annular seal 203 from being removed from the retaining groove. The stop 204 can also stop the annular seal 203 to prevent it from moving with the first connecting member 201.

[0157] As an example, the annular seal 203 has a first annular rib 2031 on its annular outer wall, which elastically abuts against the sidewall of the retaining groove. Multiple first annular ribs 2031 may be present, and any two adjacent first annular ribs 2031 are spaced apart. When the annular seal 203 is located in the retaining groove, the first annular ribs 2031 are elastically deformed by the pressure of the sidewall of the retaining groove, thereby providing a seal between the annular seal 203 and the sidewall of the retaining groove. Furthermore, the first annular ribs 2031 help reduce the resistance when the annular seal is assembled into the retaining groove. Simultaneously, the groove between two adjacent first annular ribs 2031 can lock in fluid to prevent leakage from the retaining groove.

[0158] As an example, the annular seal 203 has a second annular rib 2032 on its annular inner wall, which elastically abuts against the outer wall of the first connecting member 201. Multiple second annular ribs 2032 can be present, and any two adjacent second annular ribs 2032 are spaced apart. By providing the second annular ribs 2032, a sealing connection between the annular seal 203 and the first connecting member 201 is achieved. Although this reduces the contact area between the annular seal 203 and the first connecting member 201, it also reduces the resistance to the movement of the first connecting member 201 relative to the second connecting member 202, and also reduces the resistance to the first connecting member 201 passing through the port of the second connecting member 202.

[0159] As an example, the annular seal 203 has a third annular rib 2033 protruding towards the support wall, which elastically abuts against the support wall. Multiple third annular ribs 2033 may be present, with any two adjacent ribs spaced apart, thus creating a flow-locking groove 2034 between adjacent ribs. This flow-locking groove 2034 prevents fluid from flowing between the sidewall of the retaining groove and the annular seal 203. Furthermore, under the stop of the stop member 204, the third annular rib 2033 is compressed and undergoes elastic deformation, thereby providing a seal between the annular seal 203 and the support wall of the retaining groove.

[0160] In some embodiments, the first housing 22 includes a first sidewall 223 disposed on a lateral side of the pump body 21 and a base 224 disposed on a longitudinal side of the pump body 21. At least a portion of the second connecting member 202 is disposed between the first sidewall 223 and the pump body 21, and the second connecting member 202 connects to the base 225. Preferably, the second connecting member 202 is integrally injection molded with the first housing 22.

[0161] In some embodiments, the pump module 2 further includes a decorative shell 205, which is assembled to the first housing 22, and at least partially disposed between the movable component 23 and the decorative shell 205. When the operating member 28 is operated, the operating member 28 can slide along the decorative shell 205 or the first sidewall 223.

[0162] Furthermore, the stop 204 is connected to the decorative shell 205. Even further, the stop 204 and the decorative shell 205 are integrally injection molded.

[0163] In some embodiments, the first connecting member 201 is configured to be longitudinally movable. The first connecting member 201 includes a first tubular portion extending laterally and a second tubular portion extending longitudinally. The first tubular portion may be directly connected to the movable component 23, or the first tubular portion may be indirectly connected to the movable component via an operating member 28. The second tubular portion is nested with the second connecting member 202, such that at least a portion of the second connecting member 202 extends longitudinally, and the first connecting member 201 is longitudinally movable relative to the second connecting member 202.

[0164] Preferably, the first tubular portion and the second tubular portion are connected such that the first connecting member is approximately L-shaped. Preferably, the first tubular portion and the second tubular portion have the same inner diameter.

[0165] It should be noted that the second tubular portion and the second connecting member 202 are nested together, which may include at least partially embedded in the second connecting member 202, or at least partially embedded in the second connecting member 202.

[0166] In some embodiments, reference may be made to Figure 9 The first through hole 241 is formed on the first side wall 223. The first channel 251 includes a first part 2511 disposed between the first side wall 223 and the pump body 21 and a second part 2512 disposed in the base 225. The first part 2511 is used to connect the first through hole 241 and the second part 2512. The first part 2511 and the second part 2512 can be arranged vertically.

[0167] Furthermore, one can refer to Figure 11 The base 225 supports the bottom of the pump body 21, and the bottom of the pump body 21 is provided with a first connecting hole 212 for connecting the pump chamber 211 and the second part 2512. Furthermore, a second valve 262 is used to seal the first connecting hole 212. Even further, the second valve 262 is disposed within the pump body 21, or the second valve 262 is disposed between the pump body 21 and the base 225.

[0168] In some embodiments, the base 225 includes a soft seat 2252 and a base 2251 supporting the soft seat 2252, wherein the hardness of the base 2251 is greater than that of the soft seat 2252. For example, the soft seat 2252 may be made of silicone or rubber, and the base 2251 may be made of injection molded material, metal, ceramic, or wood. The soft seat 2252 and the base 2251 can be connected by assembly.

[0169] The second part 2512 is disposed between the base 2251 and the flexible seat 2252. The flexible seat 2252 is used to provide a sealing communication between the first part 2511 and the second part 2512, and / or to provide a sealing communication between the second part 2512 and the pump chamber 211. The flexible seat 2252 helps to prevent fluid leakage between the first part 2511 and the second part 2512, and / or to prevent fluid leakage between the first communication hole 212 and the second part 2512.

[0170] In such Figure 9 In the illustrated embodiment, the base 2251 and the flexible seat 2252 jointly define the boundary of the second portion 2512. The flexible seat 2252 has a second connecting hole 2061 and a third connecting hole 2062. The second connecting hole 2061 connects the first portion 2511 and the second portion 2512, and the third connecting hole 2062 connects the second portion 2512 and the pump chamber 211. Typically, at least one of the base 2251 and the flexible seat 2252 is provided with a flow guide groove, and at least a portion of the second portion 2512 is located in the flow guide groove. Preferably, the second connecting hole 2061 and the third connecting hole 2062 are respectively provided at both ends of the flow guide groove, such that the second connecting hole 2061 connects one end of the flow guide groove to the first portion 2511, and the third connecting hole 2062 connects the other end of the flow guide groove to the first connecting hole 212.

[0171] In some embodiments, a second through hole 242 is formed on the base 225. Further, the base 225 is configured to be connected to the liquid storage module 3. Preferably, the base 225 is provided with a protrusion 207 extending in a direction away from the first sidewall 223 or the pump body 21, the protrusion 207 being used for snap-fit ​​connection or threaded connection with the liquid storage module 3.

[0172] In some embodiments, reference may be made to Figure 2 and Figure 12 The base 225 includes a first connector 2253 protruding in a direction away from the pump body 21, and a second through hole 242 is formed in the first connector 2253. When the pump module 2 is connected to the liquid storage module 3, at least a portion of the first connector 2253 can extend into the liquid storage module 3.

[0173] Typically, one can refer to Figure 16 The liquid storage module 3 includes a liquid storage cup 32 with a second storage cavity 31 and a rubber stopper 33 for sealing the port of the liquid storage cup 32. The rubber stopper 33 is provided with a first flow guide hole 331 and a first sealing membrane 332 for sealing the first flow guide hole 331. When the pump module 2 is connected to the liquid storage module 3, at least a portion of the first connector 2253 extends into the first flow guide hole 331 and punctures or expands the first sealing membrane 332, so that the second storage cavity 31 communicates with the second through hole 242. Furthermore, the first sealing membrane 332 is configured to recover after the pump module 2 is separated from the liquid storage module 3, thereby resealing the first flow guide hole 331.

[0174] In some embodiments, reference may be made to Figure 1 , Figure 7 and Figure 10 The pump module 2 also includes a third through hole 243 for connecting the first fluid source and a fourth through hole 244 for connecting the second fluid source. A third channel 253 is established between the third through hole 243 and the fourth through hole 244, so that the first fluid source and the second fluid source can be connected through the third channel 253.

[0175] Furthermore, both the third through-hole 243 and the fourth through-hole 244 are disposed on the first housing 22. Typically, the pump module 2 can be connected to the atomizing module 1 through the first housing 22, and when the first housing 22 is connected to the atomizing module 1, the first storage cavity 11 can communicate with the third channel 253. Similarly, the pump module 2 can be connected to the liquid storage module 3 through the first housing 22, and when the first housing 22 is connected to the liquid storage module 3, the second storage cavity 31 can communicate with the third channel 253.

[0176] As an example, the first through-hole 241 and the third through-hole 243 are adjacent and located on the same surface of the pump module 2 to facilitate simultaneous communication between the first through-hole 241 and the third through-hole 243 and the first fluid source. For instance, both the first through-hole 241 and the third through-hole 243 are disposed on the first sidewall 223. When the pump module 2 is combined with the atomizing module 1, the first sidewall 223 is connected to the atomizing module 1, so that the first through-hole 241 and the third through-hole 243 are simultaneously connected to the first storage cavity 11.

[0177] As an example, the second through hole 242 and the fourth through hole 244 are adjacent and located on the other surface of the pump module 2. For instance, both the second through hole 242 and the fourth through hole 244 are provided on the base 225. When the pump module 2 is combined with the liquid storage module 3, the base 225 is connected to the liquid storage module 3, so that the second through hole 242 and the fourth through hole 244 are simultaneously connected to the second storage cavity 31.

[0178] In some embodiments, the first through hole 241 and the second through hole 242 are respectively opened on the outer surfaces of the pump module 2 with different orientations. The first fluid source and the second fluid source can be respectively disposed on the outer surfaces of the pump module 2 with different orientations. Typically, the atomizing module 1 is disposed as the first fluid source corresponding to the outer surface of the pump module 2 with the first orientation, and the first through hole 241 is opened on the outer surface of the pump module 2 with the first orientation; the liquid storage module 3 is disposed as the second fluid source corresponding to the outer surface of the pump module 2 with the second orientation, and the second through hole 242 is opened on the outer surface of the pump module 2 with the second orientation; thereby, the space of the atomizing module 1, the pump module 2 and the liquid storage module 3 can be reasonably allocated in the aerosol generating device 100.

[0179] In some embodiments, a first fluid path connects the first through-hole 241 and the second through-hole 242, and a second fluid path connects the third through-hole 243 and the fourth through-hole 244. As an example, the first fluid path includes a first channel 251, the pump chamber 211, the internal space of the drive assembly 23, and a second channel 252. As an example, the second fluid path includes a third channel 253.

[0180] In some embodiments, when the pump module 2 is running or the movable component 23 is running, the gas in the first storage chamber 11 can be drawn into the pump chamber 211 through the first channel 251, thereby reducing the gas pressure in the first storage chamber 11. The liquid matrix in the second storage chamber 31 can flow into the first storage chamber 11 through the third channel 253 to replenish the liquid matrix in the first storage chamber 11. As the pump module 2 or the movable component 23 continues to run, the gas in the pump chamber 211 can be introduced into the second storage chamber 31 through the second channel 252 to compensate for the gas pressure loss in the second storage chamber 31 due to the discharge of the liquid matrix.

[0181] In some embodiments, when the pump module 2 is running or when the movable component 23 is running, the gas in the pump chamber 211 can be introduced into the second storage chamber 31 through the second channel 252 to increase the gas pressure in the second storage chamber 31. Based on the pressure difference between the second storage chamber 31 and the first storage chamber 11, the second storage chamber 31 injects liquid matrix into the first storage chamber 11 through the third channel 253. Because the liquid matrix increases, the first storage chamber 11 discharges gas into the pump chamber 211 through the first channel 251, thereby preventing the liquid matrix from leaking through the atomizing core 15 due to excessive gas pressure in the first storage chamber 11.

[0182] In some embodiments, when the pump module 2 is running or when the movable component 23 is running, the pump chamber 211 draws liquid matrix from the second storage chamber 31 through the second channel 252, and then at least a portion of the drawn liquid matrix is ​​introduced into the first storage chamber 11 through the first channel 251, while the gas in the first storage chamber 11 flows to the second storage chamber 31 through the third channel 253.

[0183] In some embodiments, reference may be made to Figure 16 The liquid storage module 3 includes a fourth connecting member 34 disposed in the second storage cavity 31. The fourth connecting member 34 is used to connect the third channel 253 or the second channel 252. The second storage cavity 31 includes a proximal end near the rubber stopper 33 and a distal end away from the rubber stopper 33. The second end of the fourth connecting member 34 is disposed adjacent to the distal end of the second storage cavity 31, thereby facilitating the immersion of the liquid matrix in the second storage cavity 31 in the second end of the fourth connecting member 34 when the pump module 2 or the aerosol generating device 100 is in the first posture, and further facilitating the flow of the liquid matrix in the second storage cavity 31 to the first storage cavity 11 or the pump chamber 211 through the fourth connecting member 34.

[0184] In some embodiments, reference may be made to Figure 10 The first housing 22 includes a second connector 2254 protruding in a direction away from the pump body 21, and a fourth through hole 244 is formed in the second connector 2254. When the pump module 2 is connected to the liquid storage module 3, at least a portion of the second connector 2254 can extend into the liquid storage module 3.

[0185] Typically, one can refer to Figure 16 The plug 33 of the liquid storage module 3 is provided with a second flow guide hole and a second sealing membrane 334 for sealing the second flow guide hole 333. When the pump module 2 is connected to the liquid storage module 3, at least a portion of the second connector 2254 extends into the second flow guide hole 333 and punctures or expands the second sealing membrane 334, so that the second storage cavity 31 communicates with the fourth through hole 244. Furthermore, the second sealing membrane 334 is configured to recover after the pump module 2 is separated from the liquid storage module 3, thereby resealing the second flow guide hole 333.

[0186] In some embodiments, reference may be made to Figure 10 and Figure 11 The pump module 2 includes a resilient opening / closing portion 2063, which is configured to open when there is a pressure difference between the third channel 253 and the second fluid source, thereby connecting the third channel 253 and the second fluid source. The resilient opening / closing portion 2063 can be disposed between the third channel 253 and the fourth through hole 244. The fourth through hole 244 can be formed on the flexible base 2252. The resilient opening / closing portion 2063 can be disposed within the fourth through hole 244. The resilient opening / closing portion 2063 can open and close in both directions. Alternatively, it can open and close in one direction. The resilient opening / closing portion 2063 can be formed on the flexible base 2252.

[0187] In some embodiments, reference may be made to Figure 8 and Figure 10 The pump module 2 also includes a third valve 263 for sealing the third through hole 243. When the atomizing module 1 is connected to the pump module 3, the third valve 263 deforms or shifts, thereby opening the third through hole 243, allowing the first storage cavity 11 to communicate with the third channel 253. The third valve 263 may be disposed on the first housing 22.

[0188] The third valve 263 may include a third inner sealing part 2631. The third valve 263 can seal the third through hole 243 through the third inner sealing part 2631, and can open the third through hole 243 when the third inner sealing part 2631 is displaced or deformed inward.

[0189] Furthermore, the third valve 263 may also include a third abutment portion 2632 that can be abutted by a foreign object. The third inner sealing portion 2631 seals the third through hole 243 when it is in the initial state or when the third abutment portion 2632 is not abutted by a foreign object. When a foreign object abuts the third abutment portion 2632, causing the third inner sealing portion 2631 to shift or deform, the third through hole 243 opens, allowing fluid to flow into or out of the pump chamber 211 through the third through hole 243.

[0190] Furthermore, the third valve 263 includes a third annular base 2634 and a third elastic portion 2633 connecting the third annular base 2634 and the third inner sealing portion 2631. Preferably, the third valve 263 has the same structural features as the first valve 261. More preferably, the third valve 263 has the same size as the first valve 261. The fifth valve 131 may have the same structural features as the first valve 261.

[0191] In some embodiments, a first hole 227 communicating with a first channel 251 is provided on the end of the first housing 22. The first hole 227 may be an injection hole of the first housing 22. In some embodiments, a decorative shell 205 is configured to cover the first hole 227. Further, a first plug 2051 is provided on the decorative shell 205, which seals the first hole 227 when the decorative shell 205 is connected to the first housing 22. In some embodiments, a second hole 228 communicating with a third channel 253 is provided on the end of the first housing 22. The second hole 228 may be an injection hole of the first housing 22. In some embodiments, the decorative shell 205 is configured to cover the second hole 228. Further, a second plug 2052 is provided on the decorative shell 205, which seals the second hole 228 when the decorative shell 205 is connected to the first housing 22. Preferably, the first hole 227 and the second hole 228 are located on the same end of the first housing 22.

[0192] In some embodiments, the third through hole 243 includes a third outer hole 2432 formed on the first cover 222 and a third inner hole 2431 formed on the first base 221. The third valve 263 is at least partially disposed between the first cover 222 and the first base 221, and the third valve 263 seals the third outer hole 2432 when the third valve 263 is not abutted by a foreign object.

[0193] In some embodiments, the first sidewall 223 further has a sixth groove 2234 that is recessed relative to the first groove 2232, and the third inner sealing portion 2631 is located in the sixth groove 2234. Further, the sixth groove 2234 and the fourth groove 2233 are spaced apart, and the third annular base 2634 is interference-fitted into the sixth groove 2234. The third annular base 2634 can also be fixedly connected to the first cover 222 by means of bonding, welding, snap-fit ​​connection, or threaded connection. Preferably, when the atomizing module 1 is connected to the pump module 2, the fifth valve 131 abuts against the first valve 261, and the sixth valve 19 abuts against the third valve 263.

[0194] A third blocking part 226 is provided between the first cover 222 and the first base 221. When the third abutting part 2632 is abutted, causing the third inner sealing part 2631 to deform or shift, the third blocking part 226 can prevent the third inner sealing part 2631 from sealing the third inner hole 2431.

[0195] In some embodiments, reference may be made to Figure 1 The second housing 12 is provided with a sixth through hole 18 for fluid to flow into or out of the first storage cavity 11. The atomizing module 1 also includes a sixth valve 19 disposed on the second housing 12 to seal the sixth through hole 18.

[0196] The sixth valve 19 may include a sixth inner sealing part 191 and a sixth abutting part 192 that can be abutted by a foreign object. The sixth inner sealing part 191 seals the sixth through hole 18 in the initial state or when the sixth abutting part 192 is not abutted by a foreign object. When a foreign object abuts the sixth abutting part 192, causing the sixth inner sealing part 191 to shift or deform, the sixth through hole 18 opens, allowing fluid to flow into or out of the first storage cavity 11 through the sixth through hole 18.

[0197] Furthermore, the sixth valve 19 includes a sixth annular base 194 and a sixth elastic portion 193 connecting the sixth annular base 194 and the sixth inner sealing portion 191. Preferably, the sixth valve 19 has the same structural features as the fifth valve 131. More preferably, the sixth valve 19 has the same size as the fifth valve 131.

[0198] In some embodiments, when the atomizing module 1 is connected to the pump module 2, the pump module 2 abuts against the fifth valve 131 and the sixth valve 19 simultaneously, so that the fifth through hole 141 and the sixth through hole 18 can be opened synchronously. The direction in which the pump module 2 abuts against the fifth valve 131 and the direction in which it abuts against the sixth valve 19 can be the same.

[0199] In some embodiments, reference may be made to Figure 6 The sixth through hole 18 includes a fourth outer hole 182 formed on the second cover 122 and a fourth inner hole 181 formed on the second base 121. The sixth valve 19 is at least partially disposed between the second cover 122 and the second base 121, and the sixth valve 19 seals the fourth outer hole 182 when the sixth valve 19 is not abutted by a foreign object.

[0200] In some embodiments, the second outer sealing portion 1221 has a first sealing rib 1B arranged around the fourth outer hole 182, and the first outer sealing portion 2221 has a first sealing groove 2B arranged around the third outer hole 2432. When the second cover 122 is in close contact with the first cover 222, the first sealing rib 1B is embedded in the first sealing groove 2B, and along the direction in which the first cover 222 is in close contact with the second cover 122, the first sealing rib 1B elastically abuts against the first outer sealing portion 2221.

[0201] In some embodiments, the second sidewall 123 further has a fifth groove 1234 that is further recessed relative to the second groove 1232, and the sixth inner sealing portion 191 is located in the fifth groove 1234. Further, the fifth groove 1234 is spaced apart from the third groove 1233, and the sixth annular base 194 is interference-fitted into the fifth groove 1234. The sixth annular base 194 can also be fixedly connected to the second cover 122 by means of bonding, welding, snap-fit ​​connection, or threaded connection.

[0202] Furthermore, a fourth blocking portion 126 is provided between the second base 121 and the second cover 122, so that when the sixth abutting portion 192 is abutted and the sixth inner sealing portion 191 is deformed or displaced, the sixth inner sealing portion 191 can be prevented from sealing the fourth inner hole 181.

[0203] In some embodiments, reference may be made to Figure 9 The pump module 2 also includes a fourth valve 264 and a fourth channel 254 for connecting the second fluid source with the interior of the first housing 22. The fourth valve 264 is movably disposed in the fourth channel 254, and the fourth channel 254 is configured to be open when the pump module 2 is in a first position and closed when the pump module 2 is in a second position. Typically, when the pump module 2 is connected to the liquid storage module 3, if the pump module 2 is in the first position, the interior space of the first housing 22 is connected to the second storage chamber 31 through the fourth channel 254. Thus, when the air pressure in the second storage chamber 31 is lower than the air pressure in the interior space of the first housing 22, air can be introduced into the second storage chamber 31 through the fourth channel 254 to replenish the air pressure in the second storage chamber 31. When the air pressure in the second storage chamber 31 is higher than the air pressure in the interior space of the first housing 22, gas can be discharged from the second storage chamber 31 into the interior space of the first housing 22 through the fourth channel 254 to reduce the air pressure in the second storage chamber 31. Therefore, when pump module 2 is in the first position, the fourth channel 254 can be in the normally open state (see reference). Figure 1 As shown, when pump module 2 is in the second position, the fourth channel 254 can be in a normally closed state. When pump module 2 is in the first position, atomizing module 1 can generate aerosol which can then be drawn in by the user. When pump module 2 is in the second position, the operation of pump module 2 can transfer the liquid matrix in the first storage chamber 11 to the second storage chamber 31 for storage.

[0204] In some embodiments, reference may be made to Figure 9 and Figure 11 The first housing 22 includes a third connector 2255 protruding in a direction away from the pump body 21, and at least a portion of the fourth channel 254 or the fourth valve 264 is disposed in the third connector 2255.

[0205] Furthermore, one can refer to Figure 16 The plug 33 of the liquid storage module 3 is provided with a third flow guide hole 335 and a third sealing membrane 336 for sealing the third flow guide hole 335. When the pump module 2 is connected to the liquid storage module 3, at least a portion of the third connector 2255 extends into the third flow guide hole 335 and punctures or expands the third sealing membrane 336, so that the second storage cavity 31 communicates with the fourth channel 254. Furthermore, the third sealing membrane 336 is configured to recover after the pump module 2 is separated from the liquid storage module 3, thereby resealing the third flow guide hole 335.

[0206] In some embodiments, reference may be made to Figure 9 The third connector 2255 is located on the side of the base 2251 opposite to the soft seat 2252. The soft seat 2252 has a boss 2064 and a fourth connecting hole 2065 opened on the boss 2064. The boss 2064 protrudes into the fourth channel 254, and the fourth valve 264 can move in the fourth channel 254. When the pump module 2 is in the first posture, the fourth valve 264 moves away from the boss 2064 under its own gravity, thereby opening the fourth connecting hole 2065, and thus the internal space of the first housing 22 communicates with the second storage cavity 31. When the pump module 2 is in the second posture, the fourth valve 264 can automatically move to abut against the boss 2064 under its own gravity or under other forces. The boss 2064 can undergo elastic deformation under the abutment of the fourth valve 264 to adapt to the position or shape of the fourth valve 264, thereby enabling the fourth valve 264 to seal the fourth connecting hole 2065 well.

[0207] In some embodiments, reference may be made to Figure 9 and Figure 14 The pump module 2 also includes an annular wall 208 surrounding the pump body. There is a gap between the annular wall 208 and the pump body 21. A fifth connecting hole 2081 is provided on the annular wall 208 to connect with the outside atmosphere. The gap connects the fourth connecting hole 2065 and the fifth connecting hole 2081.

[0208] Preferably, at least a portion of the second connecting member 202 is disposed between the first sidewall 223 and the annular wall 208. Preferably, at least a portion 2511 of the first channel 251 and / or at least a portion of the third channel 253 is disposed between the first sidewall 223 and the annular wall 208.

[0209] In some embodiments, reference may be made to Figure 4 The atomizing module 1 also includes a locking portion 10 extending outward from the second housing 12. When the atomizing module 1 is connected to the pump module 2, the locking portion 10 is fitted into the pump module 2 and locked to provide force to keep the second housing 12 connected to the first housing 22. Alternatively, by partially fitting the atomizing module 1 into the pump module 2, the second housing 12 and the first housing 22 can be kept in close contact, thereby preventing fluid leakage between the second housing 12 and the first housing 22. Compared to using a partial fitting of the pump module into the atomizing module to maintain a stable connection, the solution of this embodiment can facilitate the miniaturization of the atomizing module 1 containing the atomizing core 15 and prevent a reduction in the capacity of the first storage cavity 11. It also facilitates a reduction in the thickness of the second sidewall 123 and allows the inner wall of the second sidewall 123 to define a portion of the boundary of the first storage cavity 11.

[0210] Furthermore, one can refer to Figure 4The locking part 10 extends outward from the second side wall 123, so that when the atomizing module 1 is connected to the pump module 3, the locking part 123 can be completely embedded in the first side wall 223, so that the outer wall of the second side wall 123 is in close contact with the outer wall of the first side wall 223.

[0211] In such Figure 4 In the embodiment described, the locking part 10 includes an extension part 101 and a latching part 102 disposed on the extension part 101. When the extension part is fitted into the first housing 22, the latching part 102 is latched to the pump module 2 to prevent the atomizing module 1 from separating from the pump module 2.

[0212] Preferably, the locking portion 10 has multiple parts, thereby increasing the tightness of the connection between the atomizing module 1 and the pump module 2. More preferably, it includes at least three locking portions 10, wherein the at least three locking portions 10 are arranged in a triangular pattern, so as to make the connection between the atomizing module 1 and the pump module 2 more stable.

[0213] In some embodiments, reference may be made to Figure 7 An embedding groove 2235 is provided on the first sidewall 223 for the locking part 10 to be embedded in. The cross-sectional area of ​​the embedding groove 2235 is larger than that of the locking part 10 to facilitate the locking part 10 to fit into the embedding groove 2235. Thus, the locking part 10 is in clearance fit with the first housing 22 in the embedding groove 2235. Furthermore, an anti-sway hole 2C is also provided on the first sidewall 223, and an anti-sway pin 1C protrudes from the second sidewall 123. The cross-sectional area of ​​the anti-sway hole 2C is approximately equal to that of the anti-sway pin 1C, or the cross-sectional area of ​​the anti-sway pin 1C is slightly larger than that of the anti-sway hole 2C. Thus, when the second sidewall 123 is close to the first sidewall 223, the anti-sway pin 1C can fit into the anti-sway hole 2C without gap, so as to prevent the atomizing module 1 and the pump module 2 from shaking relative to each other. Preferably, there are multiple anti-sway holes 2C and multiple anti-sway pins 1C, and when the atomizing module 1 and the pump module 2 are connected, the multiple anti-sway pins 1C are fitted into the multiple anti-sway holes 2C in a one-to-one correspondence.

[0214] In some embodiments, the aerosol generating device 100 is an electrically operated aerosol generating device, whereby the atomizing core 15 requires electrical power to atomize the liquid matrix to generate aerosol. Further, the aerosol generating device 100 also includes a power module capable of providing electrical power to the atomizing core 15 to atomize the liquid matrix and generate aerosol. The power module may include any suitable battery, such as a lithium battery, a disposable battery, or a rechargeable battery.

[0215] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
