Description

Technical Field

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

[0002] An aerosol generating device is a device comprising an atomizer, the atomizer having a storage chamber for storing an aerosol generating matrix and an atomizing component for atomizing the aerosol generating matrix to generate an aerosol. An exemplary aerosol generating device exists in which the atomizer can be coupled with an external component, and when coupled, the external component can be in fluid communication with the storage chamber of the atomizer through a through-hole formed in the atomizer. However, fluid leakage can occur at the junction of the atomizer and the external component. Utility Model Content

[0003] The purpose of this application is to provide an atomizing module, a pump module, and an aerosol generating device, wherein the atomizing module can be stored separately and can prevent fluid leakage between the atomizing module and the external mechanism when the atomizing module is connected to the external mechanism.

[0004] At least one embodiment of this application provides an atomizing module, the atomizing module comprising:

[0005] A first housing, the first housing having a first storage cavity for storing an aerosol generation matrix and a first through hole for providing fluid inflow or outflow from the first storage cavity;

[0006] Atomizing core, used to atomize the aerosol generating matrix to produce an aerosol; and

[0007] A first valve is disposed on the first housing. The first valve includes a first inner sealing part, which is located in the first housing and is used to seal the first through hole.

[0008] The atomizing module is configured such that when connected to an external mechanism, the first inner sealing part can be driven to move or deform along a first direction, thereby opening the first through hole, and automatically sealing the first through hole when the external mechanism is removed.

[0009] The first housing is further provided with a first external sealing part, which at least partially surrounds the first through hole and is used to provide a seal between the first housing and the external mechanism when the first through hole is open.

[0010] As an example, the first valve further includes a first elastic portion connected to the first inner seal, the first elastic portion being configured to provide an elastic force opposite to a first direction, thereby keeping the first inner seal sealing the first through hole.

[0011] As an example, the first valve further includes a first abutment portion, at least partially disposed in the first through hole or protruding from the outer wall of the first outer sealing portion, to receive abutment from an external mechanism and thereby drive the first inner sealing portion to displace.

[0012] As an example, the first housing includes a first base defining at least a portion of the boundary of the first storage cavity, the first outer sealing portion is disposed on the first base, and the first through hole includes a first inner hole formed on the first base and a first outer hole formed on the first outer sealing portion;

[0013] The first inner sealing portion is disposed between the first outer sealing portion and the first base. The first inner sealing portion is configured to be displaceable between the first outer sealing portion and the first base, and to seal the first outer hole when the first valve is not abutted by an external mechanism.

[0014] As an example, the first housing also includes a first stop portion disposed between the first inner sealing portion and the first base, the first stop portion being used to stop the first valve to prevent the first valve from being driven by an external mechanism to seal the first inner hole.

[0015] As an example, the surface of the first substrate has a first plane and a first groove recessed relative to the first plane, the first outer sealing part is disposed in the first groove, and the outer wall of the first outer sealing part is substantially flush with the first plane.

[0016] As an example, the first housing includes a first sidewall and other sidewalls, and at least a portion of the first valve is disposed in the wall of the first sidewall;

[0017] The thickness D1 of the first sidewall satisfies: 2mm ≤ D1 ≤ 4mm; or

[0018] The relationship between the thickness D1 of the first sidewall and the thickness D2 of the other sidewalls satisfies: D2≤D1≤2*D2.

[0019] As an example, the outer wall of the first outer sealing part is provided with an annular sealing groove that can be partially embedded by an external mechanism, and / or is provided with an annular sealing rib that can be squeezed by an external mechanism, the annular sealing groove or the annular sealing rib being arranged around the first through hole.

[0020] As an example, it also includes an air inlet communicating with the atomizing core and a first capillary groove communicating with the air inlet, and at least a portion of the first capillary groove extending on the outer surface of the atomizing module.

[0021] As an example, the atomizing module also includes a mouthpiece, with the inner end of the first through-hole located between the mouthpiece and the atomizing core.

[0022] At least one embodiment of this application provides a pump module configured for use in conjunction with an atomizing module, and the pump module includes:

[0023] The second housing has a second storage cavity for receiving fluid and a second through-hole for fluid to flow into or out of the second storage cavity;

[0024] A second valve is disposed on the second housing. The second valve includes a second inner sealing part, which is located in the second housing and is used to seal the second through hole.

[0025] The pump module is configured such that when connected to the atomizing module, the second inner sealing portion can be driven to displace or deform along the second direction, thereby opening the second through hole, and automatically sealing the second through hole when the atomizing module is removed;

[0026] The second housing is further provided with a second outer sealing part that mates with the first outer sealing part. The second outer sealing part at least partially surrounds the second through hole and is used to provide a seal between the first housing and the second housing when the second through hole is open.

[0027] At least one embodiment of this application provides an aerosol generating device, which includes the aforementioned atomizing module and further includes:

[0028] A pump module includes a second housing and a second valve located on the second housing. The second housing has a second storage chamber for storing fluid and a second through-hole for providing fluid inflow or outflow from the second storage chamber. The second valve includes a second inner seal for sealing the second through-hole.

[0029] When the atomizing module is connected to the pump module, the first valve and the second valve abut against each other, causing the first inner sealing part and the second inner sealing part to deform or shift in opposite directions, thereby simultaneously opening the first through hole and the second through hole, and the second housing interferes with the first outer sealing part to form a sealing ring between the first through hole and the second through hole;

[0030] The second storage chamber is configured to allow fluid to be injected into the first storage chamber through the first through-hole and the second through-hole during operation of the pump module, or to allow fluid to be extracted from the first storage chamber through the first through-hole and the second through-hole.

[0031] As an example, the atomizing module also includes a locking part;

[0032] When the atomizing module is connected to the pump module, the locking part is locked to the pump module to provide a force so that the first outer sealing part and the second housing maintain an interference fit.

[0033] As an example, it also includes a liquid storage assembly having a third storage chamber inside capable of storing fluid;

[0034] The first housing has a third through hole for fluid to flow into or out of the first storage cavity, and the atomizing module also includes a third valve disposed on the first housing to seal the third through hole;

[0035] The second housing has a fourth through hole for fluid to flow into or out of the second storage cavity. The pump module also includes a fourth valve disposed on the second housing to seal the fourth through hole, a first channel for connecting the second through hole and the second storage cavity, and a second channel for connecting the fourth through hole and the third storage cavity.

[0036] When the atomizing module is connected to the pump module, the third valve and the fourth valve deform or shift, thereby opening the third through hole and the fourth through hole, so that the first storage cavity is connected to the third storage cavity through the second channel.

[0037] The atomizing module, pump module, and aerosol generating device provided in the above embodiments include a first storage cavity for storing the aerosol generating matrix, a first housing with a first through-hole, and a first valve disposed on the first housing. The first housing includes a first outer sealing portion, the first through-hole provides fluid inflow or outflow from the first storage cavity, and the first valve includes a first inner sealing portion for sealing the first through-hole. The atomizing module is configured such that, when connected to an external mechanism, the first inner sealing portion can be driven to displace or deform along a first direction, thereby opening the first through-hole. The first outer sealing portion then interferes with the external mechanism to provide a seal between the first housing and the external mechanism, preventing fluid leakage between the atomizing module and the external mechanism. Furthermore, the first inner sealing portion is configured to automatically seal the first through-hole when the external mechanism is removed, preventing fluid leakage from the atomizing module through the first through-hole when the atomizing module or the external mechanism is removed. Thus, the atomizing module can be stored independently, and fluid leakage through the first through-hole is prevented both when the atomizing module is connected to the external mechanism and when it changes from a connected state to a disconnected state.

[0056] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0057] It should be noted that when a part is referred to as being "fixed to" another part, it can be directly on the other part or there may be an intermediate part. When a part is referred to as being "connected to" another part, it can be directly connected to the other part, or there may be one or more intermediate parts present simultaneously.

[0058] Please refer to Figure 1 This application provides an aerosol generating device 100, which includes an atomizing module 1 and a pump module 2. The atomizing module 1 has a first storage chamber 11 capable of storing fluid, and the pump module 2 has a second storage chamber 21 capable of storing fluid. When the atomizing module 1 and the pump module 2 are connected, a fluid channel can be formed between the first storage chamber 11 and the second storage chamber 21, allowing the second storage chamber 21 to inject fluid into the first storage chamber 11 or receive fluid from the first storage chamber 11. Thus, when the fluid channel is open, fluid can flow between the first storage chamber 11 and the second storage chamber 21. The fluid can be a flowable substance, such as a liquid or a gas.

[0059] It should be noted that the ability of a storage cavity to store fluid means that the fluid can be kept in the storage cavity for a long time or a short time. Keeping the fluid in the storage cavity includes the fluid being able to remain statically in the storage cavity, or the fluid flowing in the storage cavity, or the fluid flowing along the storage cavity. Therefore, the storage cavity may include a chamber or may include a pipe.

[0060] In some embodiments, the atomizing module 1 further includes a first valve 13 and a first housing 12 disposed outside the first storage cavity 11. The first housing 12 has a first through hole 14 for fluid to flow into or out of the first storage cavity 11, and the first valve 13 is disposed on the first housing 12 to seal the first through hole 14. It is understood that when the first valve 13 is in its initial state, it can seal the first through hole 14 to prevent fluid from flowing into or out of the first storage cavity 11, so that the atomizing module 1 can be stored separately.

[0061] As an example, the first housing 12 includes an annular wall 127 surrounding the first storage cavity 11. Further, the inner wall of the annular wall 127 defines at least a portion of the circumferential boundary of the first storage cavity 11. As an example, the first housing 12 also includes a base 128, which is hermetically connected to the annular wall 127 and located on one side of the first storage cavity 11. Further, the inner wall of the base 128 defines at least a portion of the bottom boundary of the first storage cavity 11. As an example, the first housing 12 includes a top wall 129 disposed opposite the base 128, which is hermetically connected to the annular wall 127 and located on one side of the first storage cavity 11. Further, the inner wall of the top wall 129 defines at least a portion of the top boundary of the first storage cavity 11. Preferably, the top wall 129 and the annular wall 127 are integrally injection molded.

[0062] In some embodiments, the inner end of the first through hole 14 is located between the base 128 and the top wall 129. The liquid matrix in the first storage cavity 11 is mainly stored between the inner end of the first through hole 14 and the base 128, so the greater the distance between the inner end of the first through hole 14 and the base 128, the more liquid matrix the first storage cavity 11 can store.

[0063] In some embodiments, the first through hole 14 is formed on the annular wall 127, such that the inner end of the annular wall 127 can penetrate the inner surface of the annular wall 127, or the outer end of the first through hole 14 can penetrate the outer surface of the annular wall 127. In other embodiments, the first through hole 14 is formed on the top wall 129.

[0064] In some embodiments, reference may be made to Figure 2 The atomizing module 1 also includes an atomizing core 15 for atomizing the aerosol generating matrix to produce aerosols.

[0065] The aerosol-generating matrix may include a liquid matrix that is liquid at room temperature. In some embodiments, the liquid matrix may contain a liquid containing tobacco-containing substances with volatile tobacco aroma components. The liquid matrix may also contain a liquid containing non-tobacco substances. The liquid matrix may contain water, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures, etc. Fragrances may include, but are not limited to, areca nut extract, menthol, peppermint, spearmint oil, various fruit flavoring components, etc. Flavorings may contain ingredients that can provide the user with various aromas or flavors. Vitamin mixtures may be mixtures containing at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but are not limited to.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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 within the first housing, and at least a portion of the outlet tube 16 is located within the first storage cavity. The longitudinal direction may be perpendicular to a first direction or a second direction. One end of the outlet tube 16 is connected to the top wall 129 of the first housing 12, and the other end is connected to the base 128 of the first housing 12.

[0071] 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.

[0072] In some embodiments, 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 an aerosol.

[0073] 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.

[0074] 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.

[0075] 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 first housing 12, or the nozzle 4 is assembled onto the first housing 12.

[0076] Preferably, the inner end of the first through hole 14 is located between the nozzle 4 and the atomizing core 15 to ensure that the liquid level of the liquid matrix in the first storage chamber 11 is higher than the end face of the atomizing core 15 facing the nozzle 3. When the atomizing core 15 is disposed in the outlet tube 16, the inner end of the first through hole 14 being located between the nozzle 4 and the atomizing core 15 also helps to increase the maximum storage capacity of the liquid matrix in the first storage chamber 11.

[0077] In some embodiments, the pump module 2 includes a second valve 23 and a second housing 22 disposed around the second storage cavity 21. The second housing 22 has a second through hole 24 for fluid to flow into or out of the second storage cavity 21. The second valve 23 is disposed on the second housing 22 to seal the second through hole 24. It is understood that, in its initial state, the second valve 23 can seal the second through hole 24 to prevent fluid from flowing into or out of the second storage cavity 21, so that the pump module 2 can be stored separately.

[0078] In some embodiments, when the atomizing module 1 is connected to the pump module 2, at least a portion of the first valve 13 and at least a portion of the second valve 23 deform or displace, thereby opening the first through hole 14 and the second through hole 24, making the first through hole 14 and the second through hole 24 connected, and thus making the first storage cavity 11 and the second storage cavity 21 connected. The second storage cavity 21 is configured to inject fluid into the first storage cavity 11 through the first through hole 14 and the second through hole 24, or to extract fluid from the first storage cavity 11 through the first through hole 14 and the second through hole 24, when the pump module 2 is running.

[0079] Furthermore, when the atomizing module 1 is connected to the pump module 2, the first housing 12 and the second housing 22 are in close contact, thereby making the first through hole 14 and the second through hole 24 in a sealed connection. This not only prevents fluid from leaking between the first housing 12 and the second housing 22, but also makes the structure of the aerosol generating device 100 compact, which helps to reduce the volume of the aerosol generating device 100.

[0080] In some embodiments, reference may be made to Figure 1 and Figure 3 When the atomizing module 1 is connected to the pump module 2, the first valve 13 and the second valve 23 abut against each other, causing at least a portion of the first valve 13 and at least a portion of the second valve 23 to deform or displace in opposite directions, thereby simultaneously opening the first through hole 14 and the second through hole 24.

[0081] In some embodiments, reference may be made to Figure 1 and Figure 3 The first valve 13 is at least partially disposed within the wall of the first housing 12. This reduces the space occupied by the first valve 13 between the atomizing module 1 and the pump module 2 when they are connected, thus helping to ensure a tight fit between the first housing 12 and the second housing 22. Furthermore, the first valve 13 is disposed outside the first storage cavity 11, so that it does not occupy space within the first storage cavity 11, and consequently, it does not affect the capacity of the first storage cavity 11.

[0082] In some embodiments, reference may be made to Figures 4-6The first housing 12 includes a first base 121 and a first cover 122. The first through hole 14 includes a first inner hole 141 formed on the first base 121 and a first outer hole 142 formed on the first cover 122. At least a portion of the first valve 13 is disposed between the first cover 122 and the first base 121, thereby at least a portion of the first valve 13 is disposed in the wall of the first housing 12. Disposing at least a portion of the first valve 12 between the first cover 122 and the first base 121 can, on the one hand, prevent the first valve 13 from being removed from the first housing 12, and on the other hand, can cover at least a portion of the first valve 13, giving the first housing 12 a more aesthetically pleasing appearance. It also allows the first valve 13 to be spaced from the first storage cavity 11 and helps to accurately install the first valve 13 in the wall of the first housing 12. When the atomizing module 1 is connected to the pump module 2, the outer surface of the first cover 122 can interfere with the second housing 22 to form a sealing ring around the outer end of the first through hole 14 or the first outer hole 142 between the first housing 12 and the second housing 22, so as to prevent fluid from leaking between the first housing 12 and the second housing 22 through the first through hole 14.

[0083] In some embodiments, reference may be made to Figure 4 and Figure 5 When the atomizing module 1 and the pump module 2 are not connected, the first valve 13 seals the first outer hole 142. The first inner hole 141 can always remain in communication with the first storage cavity 11, so that part of the fluid in the first storage cavity 11 can flow into the interval between the first cover 122 and the first base 121 through the first inner hole 141. Of course, the first valve 13 can also seal the first inner hole 141 to isolate the interval between the first cover 122 and the first base 121 from the first storage cavity 11.

[0084] In some embodiments, at least a portion of the first valve 13 deforms or displaces along a first direction upon contact with the pump module 2. The projection of the first outer hole 142 in the first direction may intersect or coincide with the projection of the first inner hole 141 in the first direction. The first outer hole 142 and the first inner hole 141 may share a common central axis.

[0085] In some embodiments, reference may be made to Figure 5 The inner wall of the first 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.

[0086] In some embodiments, reference may be made to Figure 5 and Figure 6The first housing 12 includes a first sidewall 123 and other sidewalls 124, and at least a portion of the first valve 13 is disposed in the wall of the first sidewall 123. Alternatively, the first sidewall 123 includes the first base 121 and the first cover 122.

[0087] If the thickness D1 of the first sidewall 123 is too small, the strength of the first sidewall 123 will be insufficient, and the first sidewall 123 may easily break during the process of at least partially placing the first valve 13 in the wall of the first sidewall 123. If the thickness D1 of the first 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.

[0088] In some embodiments of this application, the thickness D1 of the first sidewall 123 satisfies: 2mm ≤ D1 ≤ 4mm. For example, D1 can be approximately equal to 3mm.

[0089] In some embodiments of this application, the relationship between the thickness D1 of the first sidewall 123 and the thickness D2 of the other sidewall 124 satisfies: D2≤D1≤2*D2.

[0090] It should be noted that the thickness D1 of the first sidewall 123 mainly refers to the average thickness of the portion of the first sidewall 123 corresponding to the portion of the first storage cavity 11. The thickness D2 of the other sidewalls 124 mainly refers to the average thickness of the portions of the other sidewalls 124 corresponding to the portions of the first storage cavity 11.

[0091] Preferably, the outer wall of the first sidewall 123 can be in close contact with the pump module 2.

[0092] In some embodiments, the first valve 13 includes a first inner sealing portion 131 for sealing the first through hole 14. When the first valve 13 is interfered with by an external mechanism, the first inner sealing portion 131 is driven to displace or deform along a first direction, thereby opening the first through hole 14. When the external mechanism is removed, the first inner sealing portion 131 can automatically seal the first through hole 14.

[0093] Furthermore, the first inner sealing part 131 is disposed between the first cover 122 and the first base 121, and when the first valve 13 is in the initial state, the first inner sealing part 131 seals the first outer hole 142.

[0094] In some embodiments, reference may be made to Figures 4-6 The first valve 13 also includes a first abutment portion 132, at least partially disposed in the wall of the first housing 12, or disposed in the first through hole 14, or as shown in the figure. Figure 4 The first inner seal 131 protrudes from the outer wall of the first housing 12 to receive contact with an external mechanism, thereby driving the first inner seal 131 to move.

[0095] In such Figure 4 and Figure 5 In the illustrated embodiment, when the first valve 13 is in its initial state, at least a portion of the first abutment portion 132 protrudes through the first external hole 142 and thus lies outside the first cover 122. In such a case... Figure 1 and Figure 3 In the illustrated embodiment, when the pump module 2 abuts the first abutting portion 132, the first abutting portion 132 retracts into the first outer hole 142 or retracts into the area between the first cover 122 and the first base 121, thereby causing the first inner sealing portion 131 to open the first outer hole 142. Furthermore, when the pump module 2 abuts the first abutting portion 132, its outer end is flush with the outer wall of the first cover 122.

[0096] Preferably, the first abutting portion 132 is used to abut against the second valve 23 and is abutted by the second valve 23. Based on this, at least a portion of the first abutting portion 132 protrudes from the first outer hole 142 when the first valve 13 is in its initial state, facilitating the abutment of the first valve 13 against the second valve 23. Furthermore, when the second valve 23 abuts against the first abutting portion 132, the second valve 23 does not need to be inserted into the first through hole 14, thus eliminating the need for the second valve 23 to adapt to the size of the first through hole 14. Alternatively, when the second valve 23 abuts against the first abutting portion 132, the depth to which the second valve 23 is inserted into the first through hole 14 can be reduced, which is beneficial for reducing the size and cost of the second valve 23.

[0097] Preferably, the first abutting portion 132 is connected to the first inner sealing portion 131. More preferably, the first abutting portion 132 is connected to the central region of the first inner sealing portion 131.

[0098] In some embodiments, a first blocking portion 125 is provided between the first base 121 and the first cover 122, thereby preventing the first inner sealing portion 131 from sealing the first inner hole 141 when the first abutting portion 132 is abutted along the first direction, causing the first inner sealing portion 131 to deform or displace along the first direction. This allows the first inner hole 141 to communicate with the outside (e.g., with the second through hole 24) through the first outer hole 142 when the first outer hole 142 is open, and the first outer hole 142 to communicate with the first storage cavity 11 through the first inner hole 141. Furthermore, the first inner sealing portion 131 is disposed between the first outer hole 142 and the first blocking portion 125, and when the first valve 13 is in the initial state, the first inner sealing portion 131 isolates the first outer hole 142 from the first inner hole 141.

[0099] Furthermore, the first blocking portion 125 is disposed around the first inner hole 141, and the first blocking portion 125 has a notch or a plurality of first blocking portions 125 disposed at intervals. Even further, the first blocking portion 125 is integrally formed with the first base 121.

[0100] It should be noted that the first base 121 may include any one of the annular wall 127, the base 128, and the top wall 129.

[0101] In some embodiments, the atomizing module 1 and the pump module 2 are detachably connected, and when the two are separated, the first valve 13 can automatically reset to reseal the first through hole 14, and the second valve 23 can also automatically reset to reseal the second through hole 24.

[0102] Furthermore, you can refer to Figure 6 The first valve 13 also includes a first elastic portion 133 connected to the first inner seal portion 131. The first elastic portion 133 is configured to deform in a first direction when the first valve 13 is abutted, thereby providing resistance to the displacement of the first inner seal portion 131 in the first direction. When the atomizing module 1 separates from the pump module 2, the first elastic portion 133 provides elastic force to drive the first inner seal portion 131 to reset, causing the first inner seal portion 131 to reseal the first outer hole 142. The first elastic portion 133 also prevents the first through hole 14 from being easily opened and thus obstructed.

[0103] In some embodiments, reference may be made to Figure 3 and Figure 8 The second valve 23 is at least partially disposed in the wall of the second housing 22. This reduces the space occupied by the second valve 23 between the atomizing module 1 and the pump module 2 when the atomizing module 1 is connected to the pump module 2, which helps to ensure that the first housing 12 and the second housing 22 fit tightly together.

[0104] In some embodiments, reference may be made to Figure 3 The second housing 22 includes a second base 221 and a second cover 222. The second through hole 24 includes a second inner hole 241 formed on the second base 221 and a second outer hole 242 formed on the second cover 222. At least a portion of the second valve 23 is disposed between the second cover 222 and the second base 221, thereby at least a portion of the second valve 23 is disposed within the wall of the second housing 22. Disposing at least a portion of the second valve 23 between the second cover 222 and the second base 221 can, on the one hand, prevent the second valve 23 from being removed from the second housing 22, and on the other hand, can cover at least a portion of the second valve 23, giving the second housing 22 a more aesthetically pleasing appearance and facilitating the accurate installation of the second valve 23 within the wall of the second housing 22. When the atomizing module 1 is connected to the pump module 2, the outer surface of the second cover 222 can be interfering with the first housing 12 and the second housing 22 to form a sealing ring around the outer end of the second through hole 24 or the second outer hole 242, so as to prevent fluid from leaking between the first housing 12 and the second housing 22 through the second through hole 24.

[0105] In some embodiments, when the atomizing module 1 is not connected to the pump module 2, the second valve 23 seals the second outer hole 242. The second inner hole 241 can always remain in communication with the second storage cavity 21, so that a portion of the fluid in the second storage cavity 21 can flow into the second inner hole 241 through the interval between the second cover 222 and the second base 221. Of course, the second valve 23 can also seal the second inner hole 241 to isolate the interval between the second cover 222 and the second base 221 from the second storage cavity 21.

[0106] In some embodiments, at least a portion of the second valve 23 deforms or displaces along the second direction upon contact with the atomizing module 1. The projection of the second outer hole 242 in the second direction may intersect or coincide with the projection of the second inner hole 241 in the second direction. The second outer hole 242 and the second inner hole 241 may share a central axis. The first direction and the second direction may be opposite.

[0107] In some embodiments, the second valve 23 includes a second inner sealing portion 231 for sealing the second through hole 24. When the second valve 23 is interfered with by an external mechanism, the second inner sealing portion 231 is driven to displace or deform along a second direction, thereby opening the second through hole 24. When the external mechanism is removed, the second inner sealing portion 231 can automatically seal the second through hole 24.

[0108] Furthermore, the second inner sealing part 231 is disposed between the second cover 222 and the second base 221, and when the second valve 23 is in the initial state, the second inner sealing part 231 seals the second outer hole 242.

[0109] In some embodiments, reference may be made to Figure 7 and Figure 8 The second valve 23 further includes a second abutment portion 232, at least partially disposed in the wall of the second housing 22, or disposed in the second through hole 24, or as shown in the figure. Figure 7 The second inner seal 231 protrudes from the outer wall of the second housing 22 to receive the abutment of the external mechanism and thereby drive the second inner seal 231 to move.

[0110] In such Figure 7 In the illustrated embodiment, when the second valve 23 is in its initial state, the second abutment portion 232 protrudes from the second outer hole 242 and thus lies outside the second cover 222. In such a case... Figure 1 and Figure 3 In the illustrated embodiment, when the second abutting portion 232 is abutted by the atomizing module 1, it retracts into the second outer hole 242 or into the area between the second cover 222 and the second base 221, thereby causing the second inner sealing portion 231 to open the second outer hole 242. Furthermore, when the second abutting portion 232 is abutted by the atomizing module 1, its outer end is flush with the outer wall of the second cover 222.

[0111] Preferably, the second abutting portion 232 is used to abut against and be abutted by the first abutting portion 132. Based on this, at least a portion of the second abutting portion 232 protrudes from the second outer hole 242 when the second valve 23 is in its initial state, facilitating the abutting portion 232 against the first abutting portion 142. Furthermore, when the first abutting portion 132 abuts against the second abutting portion 232, the first abutting portion 132 does not need to be inserted into the second through hole 24, thus eliminating the need for the first abutting portion 132 to adapt to the size of the second through hole 24. Alternatively, when the first abutting portion 132 abuts against the second abutting portion 232, the depth to which the first abutting portion 132 is inserted into the second through hole 24 can be reduced, which is beneficial for reducing the length of the first abutting portion 132. Similarly, if at least a portion of the first abutment portion 132 protrudes from the first outer hole 142 when the first valve 13 is in the initial state, then it is not necessary to adapt the second abutment portion 232 to the size of the first through hole 14, or the length of the second abutment portion 232 can be shortened.

[0112] Preferably, the second abutment portion 232 is connected to the second inner sealing portion 231. More preferably, the second abutment portion 232 is connected to the central region of the second inner sealing portion 231.

[0113] In some embodiments, a second blocking portion 225 is provided between the second base 221 and the second cover 222, thereby preventing the second inner sealing portion 231 from sealing the second inner hole 241 when the second abutting portion 232 is abutted along the second direction, causing the second inner sealing portion 231 to deform or displace along the second direction. This allows the second inner hole 241 to communicate with the outside (e.g., with the first through hole 14) through the second outer hole 242 when the second outer hole 242 is open, and the second outer hole 242 to communicate with the second storage cavity 21 through the second inner hole 241. Furthermore, the second inner sealing portion 231 is disposed between the second outer hole 242 and the second blocking portion 225, and when the second valve 23 is in the initial state, the second inner sealing portion 231 isolates the second outer hole 242 from the second inner hole 241.

[0114] Furthermore, the second blocking portion 225 is disposed around the second inner hole 241, and the second blocking portion 225 has a notch or a plurality of second blocking portions 225 disposed at intervals. Even further, the second blocking portion 225 is integrally formed with the second base 221.

[0115] In some embodiments, reference may be made to Figure 8The second valve 23 also includes a second elastic portion 233 connected to the second inner seal portion 231. The second elastic portion 233 is configured to deform in a second direction when the second valve 23 is abutted, thereby providing resistance to the displacement of the second inner seal portion 231 in the second direction. When the atomizing module 1 is separated from the pump module 2, the second elastic portion 233 provides elastic force to drive the second inner seal portion 231 to reset, causing the second inner seal portion 231 to reseal the second outer hole 242. The second elastic portion 233 also prevents the second through hole 24 from being easily opened and thus obstructed.

[0116] In some embodiments, the first housing 12 includes a first outer sealing portion 1221, which is used to interfere with an external mechanism to form a sealing ring surrounding the outer end of the first through hole 14 between the first housing 12 and the external mechanism.

[0117] As an example, when the atomizing module 1 is stored alone or when it is not connected to an external mechanism, the first inner sealing part 131 seals the first outer hole 142 inside the first outer hole 142. When the atomizing module 1 is connected to an external mechanism, the sealing ring formed between the first outer sealing part 1221 and the external mechanism seals the first outer hole 142 outside the first outer hole 142, thereby preventing fluid leakage between the first housing 12 and the external mechanism.

[0118] As an example, you can refer to Figure 3 and 4 The first cover 122 includes a first outer sealing portion 1221, and at least a portion of the first outer hole 142 is formed on the first outer sealing portion 1221. When the first cover 122 interferes with the second cover 222, the first outer sealing portion 1221 elastically abuts against the second cover 222, thereby providing a seal between the first cover 122 and the second cover 222, which helps to prevent fluid leakage from between the first cover 122 and the second cover 222. Preferably, the first outer sealing portion 1221 is elastic, so that during the connection of the atomizing module 1 and the pump module 2, the first outer sealing portion 1221 can also reduce the impact between the atomizing module 1 and the pump module 2.

[0119] In some embodiments, the second housing 22 includes a second outer sealing portion 2221, which is used to interfere with an external mechanism to form a sealing ring surrounding the outer end of the second through hole 24 between the second housing 22 and the external mechanism.

[0120] As an example, when pump module 2 is stored alone or when pump module 2 is not connected to an external mechanism, the second inner seal 231 seals the second outer hole 242 from the inside. When pump module 2 is connected to an external mechanism, the sealing ring formed between the second outer seal 2221 and the external mechanism seals the second outer hole 242 from the outside, thereby preventing fluid leakage between the second housing 22 and the external mechanism.

[0121] As an example, you can refer to Figure 7 and Figure 8 The second cover 222 includes a second outer sealing portion 2221, and at least a portion of the second outer hole 242 is formed on the second outer sealing portion 2221. When the first cover 122 is in close contact with the second cover 222, the second outer sealing portion 2221 elastically abuts against the first cover 122, thereby providing a seal between the first cover 122 and the second cover 222. Preferably, the second outer sealing portion 2221 is elastic.

[0122] In some embodiments, the first cover 122 includes a first outer sealing portion 1221 with elasticity, and the second cover 222 includes a second outer sealing portion 2221 with elasticity. The outer wall of the first outer sealing portion 1221 has a first sealing groove 1A surrounding the first outer hole 142, and the outer wall of the second outer sealing portion 2221 has a first sealing rib 2A surrounding the second outer hole 242. When the first cover 122 and the second cover 222 interfere, the first sealing rib 2A is fitted into the first sealing groove 1A, and along the direction in which the first cover 122 abuts against the second cover 222, the first sealing rib 2A can elastically abut against the bottom of the first sealing groove 1A. Because the first sealing rib 2A is fitted into the first sealing groove 1A, when the first sealing rib 2A elastically abuts against the bottom of the first sealing groove 1A, the first sealing rib 2A undergoes elastic deformation, causing the first sealing rib 2A to elastically press against the two side walls of the first sealing groove 1A respectively. This results in a seal between the first sealing rib 2A and the bottom of the first sealing groove 1A, and between the first sealing rib 2A and the groove walls on both sides of the first sealing groove 1A, thereby improving the sealing effect between the first cover 122 and the second cover 222 by at least 3 times.

[0123] Preferably, the distance between the groove walls on both sides of the first sealing groove 1A is at least 10% greater than the width of the first sealing rib 2A, or the distance between the groove walls on both sides of the first sealing groove 1A is at least 0.05 mm greater than the width of the first sealing rib 2A. More preferably, the distance between the groove walls on both sides of the first sealing rib 2A is at least 0.1 mm greater than the width of the first sealing rib 2A. This facilitates the entry of the first sealing rib 2A into the first sealing groove 1A.

[0124] Preferably, the difference between the spacing between the groove walls on both sides of the first sealing groove 1A and the width of the first 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 first sealing groove 1A and the width of the first sealing rib 2A is less than or equal to 0.2 mm. This ensures that after the first sealing groove 1A deforms, the first sealing rib 2A can compress the groove walls on both sides of the first sealing groove 1A, thereby forming a seal between the first sealing rib 2A and the groove walls on both sides of the first sealing groove 1A.

[0125] In some embodiments, reference may be made to Figure 4 and Figure 6 The surface of the first sidewall 123 or the first base 121 has a first plane 1231 and a first groove 1232 recessed relative to the first plane 1231. The first cover 122 is disposed in the first groove 1232, and the outer wall of the first cover 122 is substantially flush with the first plane 1231.

[0126] Furthermore, the outer wall of the first outer sealing part 1221 is substantially flush with the first plane 1231.

[0127] In some embodiments, the second housing 22 includes a second sidewall 223, which has a second plane 2231 and a second groove 2232 recessed relative to the second plane 2231. A second cover 222 is disposed in the second groove 2232, and the outer wall of the second cover 222 is substantially flush with the second plane 2231. The second sidewall 223 may include a second base 221 and a second cover 222. The outer wall of the second sidewall 223 may be in close contact with the atomizing module 1.

[0128] Furthermore, the outer wall of the second outer sealing part 2221 is substantially flush with the second plane 2231.

[0129] When the first cover 122 and the second cover 222 interfere with each other, the first plane 1231 can fit against the second plane 2231. Alternatively, the atomizing module 1 and the pump module 2 are arranged laterally, and when the first cover 122 and the second cover 222 interfere with each other, there is a very small lateral gap or no lateral gap between the first plane 1231 and the second plane 2231. This allows the atomizing module 1 and the pump module 2 to be connected very compactly.

[0130] Preferably, when the atomizing module 1 is connected to the pump module 2, the first plane 1231 and the second plane 2231 are arranged face to face and in close contact.

[0131] In some embodiments, reference may be made to Figure 6 The first sidewall 123 also has a third groove 1233 that is further recessed relative to the first groove 1232, and the first inner sealing part 131 is located in the third groove 1233.

[0132] In such Figure 6 In the embodiment shown, the first valve 13 includes a first annular base 134, one end of the first elastic part 133 is connected to the inner wall of the first annular base 134, and the other end is connected to the first inner sealing part 131.

[0133] Furthermore, the first annular base 134 is interference-fitted into the third groove 1233, which not only forms a seal between the first annular base 134 and the wall of the third groove 1233, but also fixes the first valve 13 in the third groove 1233. Multiple first elastic portions 133 may be present. The first elastic portions 133 may extend non-linearly between the first annular base 123 and the first inner sealing portion 131.

[0134] Furthermore, the first annular base 134 of the first valve 13 can be fixedly connected to the first cover 122 by means of bonding, welding, snap-fit ​​connection or threaded connection. Thus, during assembly, the first cover 122 and the first valve 13 can be assembled as an integral structure with the first base 121.

[0135] In some embodiments, the first cover 122 includes a first support member 1222, and a first outer sealing portion 1221 is disposed on the first 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.

[0136] In some embodiments, reference may be made to Figure 8 The second sidewall 223 also has a fourth groove 2233 that is further recessed relative to the second groove 2232, and the second inner sealing part 231 is located in the fourth groove 2233.

[0137] In such Figure 8 In the embodiment shown, the second valve 23 includes a second annular base 234, one end of the second elastic part 133 is connected to the inner wall of the second annular base 234, and the other end is connected to the second inner sealing part 231.

[0138] Furthermore, the second annular base 234 is interference-fitted into the fourth groove 2233, which not only forms a seal between the second annular base 234 and the wall of the fourth groove 2233, but also fixes the second valve 23 in the fourth groove 2233. Multiple second elastic portions 233 may be present. The second elastic portions 233 may extend non-linearly between the second annular base 234 and the second inner sealing portion 231.

[0139] Furthermore, the second annular base 234 of the second valve 23 can be fixedly connected to the second cover 222 by means of bonding, welding, snap-fit ​​connection or threaded connection. Thus, during assembly, the second cover 222 and the second valve 23 can be assembled as an integral structure with the second base 221.

[0140] In some embodiments, the second cover 222 includes a second support member, and the second outer sealing portion 222 is disposed on the second support member and located on the side opposite to the second storage cavity 21.

[0141] In some embodiments, reference may be made to Figure 1 The first housing 12 is provided with a third through hole 18 for fluid to flow into or out of the first storage cavity 11. The atomizing module 1 also includes a third valve 19 disposed on the first housing 12 to seal the third through hole 18.

[0142] The third valve 19 may include a third inner sealing part 191 and a third abutting part 192 that can be abutted by an external mechanism. The third inner sealing part 191 seals the third through hole 18 in the initial state or when the third abutting part 192 is not abutted by an external mechanism. When the external mechanism abuts the third abutting part 192, causing the third inner sealing part 191 to shift or deform, the third through hole 18 opens, allowing fluid to flow into or out of the first storage cavity 11 through the third through hole 18.

[0143] Furthermore, the third valve 19 includes a third annular base 194 and a third elastic portion 193 connecting the third annular base 194 and the third inner sealing portion 191. Preferably, the third valve 19 has the same structural features as the first valve 13. More preferably, the third valve 19 has the same size as the first valve 13.

[0144] In some embodiments, reference may be made to Figure 6 The third through hole 18 includes a third outer hole 182 formed on the first cover 122 and a third inner hole 181 formed on the first base 121. The third valve 19 is at least partially disposed between the first cover 122 and the first base 121, and when the third valve 19 is not abutted by an external mechanism, the third valve 19 seals the third outer hole 182.

[0145] In some embodiments, the first sidewall 123 further has a fifth groove 1234 that is further recessed relative to the first groove 1232, and the third inner sealing portion 191 is located in the fifth groove 1234. Furthermore, the fifth groove 1234 and the third groove 1233 are spaced apart, and the third annular base 194 is interference-fitted into the fifth groove 1234. The third annular base 194 can also be fixedly connected to the first cover 122 by means of bonding, welding, snap-fit ​​connection, or threaded connection.

[0146] Furthermore, a third blocking portion 126 is provided between the first base 121 and the first cover 122, so that when the third abutting portion 192 is abutted along the first direction, causing the third inner sealing portion 191 to deform or shift along the first direction, the third inner sealing portion 191 can be prevented from sealing the third inner hole 181.

[0147] In some embodiments, reference may be made to Figure 1 The aerosol generating device 100 also includes a liquid storage component 3, which has a third storage chamber 31 capable of storing fluid. When the atomizing module 1 is connected to the liquid storage component 3, or when the atomizing module 1 is connected to the pump module 2, the third through hole 18 opens, allowing fluid communication between the first storage chamber 11 and the third storage chamber 31. This allows fluid in the first storage chamber 11 to flow into the third storage chamber 31 through the third through hole 18, or vice versa. As an example, when the atomizing module 1 is connected to the liquid storage component 3, the liquid storage component 3 abuts against the third abutment portion 192 of the third valve 19, thereby causing the third valve 19 to open the third through hole 18. As an example, when the atomizing module 1 is connected to the pump module 2, the pump module 2 abuts against both the first valve 13 and the third valve 19 simultaneously, allowing the first through hole 14 and the third through hole 18 to open synchronously. The direction in which the pump module 2 abuts against the first valve 13 can be the same as the direction in which it abuts against the third valve 19.

[0148] In some embodiments, reference may be made to Figure 1 The second housing 22 has a fourth through hole 25 for fluid to flow into or out of the second storage chamber 21. The pump module 2 also includes a fourth valve 26 disposed on the second housing 22 to seal the fourth through hole 25, a first channel 271 for connecting the second through hole 24 and the second storage chamber 21, and a second channel 272 for connecting the fourth through hole 25 and the third storage chamber 31. When the atomizing module 1 is connected to the pump module 3, the third valve 19 and the fourth valve 26 deform or shift, thereby opening the third through hole 18 and the fourth through hole 25, allowing the first storage chamber 11 to connect to the second storage chamber 21 through the first channel 271, and allowing the first storage chamber 11 to connect to the third storage chamber 31 through the second channel 272. When the atomizing module 1 is connected to the pump module 2, the third through hole 18 and the fourth through hole 25 can be opened simultaneously.

[0149] The fourth valve 26 may include a fourth inner sealing part 261 and a fourth abutting part 262 that can be abutted by an external mechanism. The fourth inner sealing part 261 seals the fourth through hole 25 in the initial state or when the fourth abutting part 262 is not abutted by an external mechanism. When the external mechanism abuts the fourth abutting part 262, causing the fourth inner sealing part 261 to shift or deform, the fourth through hole 25 opens, allowing fluid to flow into or out of the second storage chamber 21 through the fourth through hole 25.

[0150] Furthermore, the fourth valve 26 includes a fourth annular base 264 and a fourth elastic portion 263 connecting the fourth annular base 264 and the fourth inner sealing portion 261. Preferably, the fourth valve 26 has the same structural features as the second valve 23. More preferably, the fourth valve 26 has the same size as the second valve 23. The first valve 13 and the second valve 23 may have the same structural features.

[0151] In some embodiments, the fourth through hole 25 includes a fourth outer hole 252 formed on the second cover 222 and a fourth inner hole 251 formed on the second base 221. The fourth valve 26 is at least partially disposed between the second cover 222 and the second base 221, and the fourth valve 26 seals the fourth outer hole 252 when the fourth valve 26 is not abutted by an external mechanism.

[0152] In some embodiments, the second sidewall 223 further has a sixth groove 2234 that is recessed relative to the second groove 2232, and the fourth inner sealing portion 261 is located in the sixth groove 2234. Further, the sixth groove 2234 and the fourth groove 2233 are spaced apart, and the fourth annular base 264 is interference-fitted into the sixth groove 2234. The fourth annular base 264 can also be fixedly connected to the second 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 first valve 13 abuts against the second valve 23, and the third valve 19 abuts against the fourth valve 26.

[0153] In some embodiments, the first outer sealing portion 1221 has a second sealing rib 1B arranged around the third outer hole 182, and the second outer sealing portion 2221 has a second sealing groove 2B arranged around the fourth outer hole 252. When the first cover 122 is in close contact with the second cover 222, the second sealing rib 1B is embedded in the second sealing groove 2B, and along the direction in which the second cover 222 is in close contact with the first cover 122, the second sealing rib 1B elastically abuts against the second outer sealing portion 2221.

[0154] In some embodiments, the pump module 2 includes a pump, and the second storage chamber 21 is configured to inject fluid into the first storage chamber 11 through the second through hole 24 or to extract fluid from the first storage chamber 11 through the second through hole 24 when the pump is running.

[0155] As an example, during pump operation, the second storage chamber 21, connected to the second through-hole 24 via the first through-hole 14, draws fluid from the first storage chamber 11, thereby reducing the gas pressure in the first storage chamber 11. This causes the gas pressure in the third storage chamber 31 to be greater than that in the first storage chamber 11, and the fluid in the third storage chamber 31 then flows into the first storage chamber 11 through the third through-hole 18 connected to the fourth through-hole 25. Typically, during pump operation, the second storage chamber 21 draws gas from the first storage chamber 11, and the third storage chamber 31 automatically injects a liquid matrix into the first storage chamber 11 based on the pressure difference.

[0156] As an example, a third channel 273 is also provided between the second storage cavity 21 and the third storage cavity 31, so that fluid can circulate between the first storage cavity 11, the second storage cavity 21 and the third storage cavity 31 based on the third channel 273, the first through hole 14 communicating with the second through hole 24, and the third through hole 18 communicating with the fourth through hole 25.

[0157] For example, during pump operation, the second storage chamber 21 injects fluid into the third storage chamber 31 through the third channel 273 to increase the gas pressure in the third storage chamber 31, making the gas pressure in the third storage chamber 31 greater than the gas pressure in the first storage chamber 11. Consequently, the fluid in the third storage chamber 31 flows into the first storage chamber 11 through the third through-hole 18 and the fourth through-hole 25. After receiving fluid from the third storage chamber 31, the first storage chamber 11 experiences an increase in gas pressure or fluid volume. Then, some of the fluid in the first storage chamber 11 flows into the second storage chamber 21 through the first through-hole 14 and the second through-hole 24. Typically, during pump operation, the second storage chamber 21 injects gas into the third storage chamber 31, and based on the pressure difference, the third storage chamber 31 automatically injects a liquid matrix into the first storage chamber 11, while the gas in the first storage chamber 11 flows into the second storage chamber 21.

[0158] Alternatively, for example, during pump operation, the second storage chamber 21 draws fluid from the third storage chamber 31 through the third channel 273. As the pump continues to operate, the second storage chamber 21 then injects at least a portion of the drawn fluid into the first storage chamber 11 through the first through-hole 14 and the second through-hole 24. After receiving fluid from the second storage chamber 21, the pressure or fluid volume in the first storage chamber 11 increases. Then, a portion of the fluid in the first storage chamber 11 can flow into the third storage chamber 31 through the third through-hole 18 and the fourth through-hole 25. Typically, during pump operation, the second storage chamber 21 draws liquid matrix from the third storage chamber 31 and then injects at least a portion of the drawn liquid matrix into the first storage chamber 11, while the gas in the first storage chamber 11 flows into the third storage chamber 31.

[0159] In some embodiments,

[0160] In some embodiments, reference may be made to Figure 4 The atomizing module 1 also includes a locking part 10. When the atomizing module 1 is connected to the pump module 2, the locking part 10 is locked to the pump module 2 to provide a force so that the first housing 12 and the second housing 22 are kept in close contact, thereby making the first through hole 14 and the second through hole 24 in a sealed connection to prevent fluid from leaking between the first housing 12 and the second housing 24.

[0161] Furthermore, the locking portion 10 extends from the first housing 12 along the second direction, and when the atomizing module 1 is connected to the pump module 2, the locking portion 10 is fitted into the pump module 2. By partially fitting the atomizing module 1 into the pump module 2, a stable connection between the two is maintained and fluid leakage from between the first housing 12 and the second housing 22 is prevented. 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 the reduction of the capacity of the first storage cavity 11, and can also facilitate the reduction of the thickness of the first sidewall 123, and allow the inner wall of the first sidewall 123 to define a portion of the boundary of the first storage cavity 11.

[0162] Furthermore, you can refer to Figure 4 The locking part 10 extends outward from the first 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 second side wall 223, so that the outer surface of the first side wall 123 can be closely attached to the outer surface of the second side wall 223.

[0163] In such Figure 4 In the embodiment described, the locking part 10 includes an extension part 101 extending in the second direction and a latching part 102 disposed on the extension part 101. When the extension part 101 is fitted into the second 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 in the second direction.

[0164] 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.

[0165] In some embodiments, reference may be made to Figure 7The second sidewall 223 is provided with an embedding groove 28 for the locking part 10 to be embedded in. The cross-sectional area of ​​the embedding groove 28 is larger than that of the locking part 10 to facilitate the locking part 10 to fit into the embedding groove 28. Thus, the locking part 10 is in clearance fit with the second housing 22 in the embedding groove 28. Furthermore, the second sidewall 223 is also provided with an anti-sway hole 2C, and an anti-sway pin 1C protrudes from the first 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 first sidewall 123 is close to the second 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.

[0166] It should be noted that the atomizing module 1, the pump module 2, and the liquid storage component 3 are external components to each other.

[0167] 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 and generate an aerosol. Furthermore, 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 an aerosol. The power module may include any suitable battery, such as a lithium battery, a disposable battery, or a rechargeable battery.

[0168] In some embodiments, reference may be made to Figure 9 The atomizing module 1 also includes an electrode X1 electrically connected to the atomizing core 15. The electrode X1 can be removably electrically connected to the power supply module, thereby facilitating the removal or replacement of the atomizing module 1 from the aerosol generating device 100.

[0169] Furthermore, the atomizing module 1 also includes a first magnetic element X2, and the aerosol generating device 100 also includes a second magnetic element (not shown). The first magnetic element X2 and the second magnetic element can be magnetically attracted to each other so that the electrode X1 and the power module can be stably electrically connected through the magnetic attraction between them, and the atomizing module 1 can be prevented from moving relative to the power module or being removed from the aerosol generating device 100 without the user's consent.

[0170] In some embodiments, reference may be made to Figure 9The atomizing module 1 also includes an air inlet 1D, through which air enters the interior of the atomizing module 1 and then flows to the atomizing core 15. A first capillary groove 1E is provided on the wall of the air inlet 1D. The first capillary groove 1E can lock the aerosol condensate flowing into the air inlet 1D, thereby preventing condensate leakage. The width of the first capillary groove 1E can be between 0.1 mm and 1 mm.

[0171] Furthermore, the first capillary groove 1E communicates with the air inlet 1D, and at least a portion of the first capillary groove 1E extends on the outer surface of the atomizing module 1. Even further, the atomizing module 1 includes a mounting hole 1F, in which the first magnetic element X2 is assembled. The end of the first capillary groove 1E extending on the outer surface of the atomizing module 1 may point towards the mounting hole 1F, or the first capillary groove 1E may extend on the outer surface of the atomizing module 1 to point towards the mounting hole 1F, thereby enabling the first capillary groove 1E to guide liquid in the air inlet 1D into the mounting hole 1F for storage. The number of first capillary grooves 1E may be the same as the number of mounting holes 1F.

[0172] In some embodiments, reference may be made to Figure 9 A second capillary groove 1G is provided on the wall of the mounting hole 1F. The second capillary groove 1G can lock the liquid introduced into the mounting hole 1F to prevent the liquid from flowing out of the mounting hole 1F. Furthermore, the second capillary groove 1G extends longitudinally. There can be multiple second capillary grooves 1G.

[0173] 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.
