Aerosol generation device

[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202410917351.2, filed on July 9, 2024, entitled "Aerosol Generating Apparatus", the entire contents of which are incorporated herein by reference. Technical Field

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

[0004] An aerosol generating device is a device capable of atomizing liquid formulations to form aerosols. However, in some exemplary prior art, an aerosol generating device includes an atomizer, a spare reservoir, and a power supply component. The spare reservoir is connected to the atomizer via a liquid circuit to replenish the liquid matrix in the atomizer's reservoir. The power supply component is electrically connected to the atomizer to provide power for atomizing the liquid matrix. The spare reservoir is detachably connected to the atomizer so that it can be replaced after the liquid matrix in the spare reservoir is depleted.

[0005] However, the atomizing coils in existing atomizers, which are used to atomize liquid substrates, have a limited atomization capacity. The sum of the liquid substrate reserves in the spare tank and the liquid substrate reserves in the atomizer is basically the upper limit of the atomizing coil's atomization capacity. When the liquid substrate in the spare tank is depleted, the atomizing coil's lifespan is not long enough to support it in continuing to atomize the liquid substrate in the new spare tank to achieve the desired effect. This not only results in waste after replacing the spare tank, but also leads to a decrease in the user experience.

[0006] Application content

[0007] The purpose of this application is to provide an aerosol generating device that allows the first module and the second module to operate independently, and also allows the first module with the atomizing core to be detached from the third module when the second module is replaced, so that the second module can be replaced simultaneously, thereby providing an aerosol generating device that meets user expectations during repeated use.

[0008] At least one embodiment of this application provides an aerosol generating apparatus, which includes:

[0009] The first module includes a first chamber for storing a liquid matrix and an atomizing core for atomizing the liquid matrix to generate an aerosol. The first chamber is in fluid communication with the atomizing core. The first module has a first end and a second end that are disposed opposite to each other.

[0010] The second module has a second chamber for storing a liquid matrix. The second module is independent of the first module and can be connected to a first end of the first module. When the second module is connected to the first module, a fluid channel can be established between them to replenish the liquid matrix from the second chamber to the first chamber.

[0011] A third module is detachably connected to the second end of the first module. The third module includes a power source, which is used to establish a power supply path between the third module and the atomizing core when the third module is connected to the first module.

[0012] The second module is configured to provide user operation to establish a connection with the first module, and to enable the first module to detach from the third module.

[0013] As an example, the second module cannot be disassembled from the first module after the connection is established.

[0014] As an example, the connection between the second module and the first module is detachable; wherein

[0015] The method of disassembling the second module after it is connected to the first module is different from the method of disassembling the third module after it is connected to the first module; or

[0016] The disassembly force of the second module after it is connected to the first module is greater than the disassembly force of the third module after it is connected to the first module.

[0017] As an example, the third module also includes a housing that is open at the proximal end, the housing having an internal receiving cavity disposed adjacent to the proximal end of the housing;

[0018] The first module is removably held in the receiving cavity, and a portion of the second module is removably held in the receiving cavity, with a portion exposed outside the housing for user operation.

[0019] As an example, the aerosol generating apparatus further includes a fourth module configured to be partially housed within the receiving cavity and to expose a first end of the first module upon removal from the receiving cavity.

[0020] As an example, the second module is configured to move relative to the first module between a first position and a second position;

[0021] The fluid channel is disconnected when the second module is in the first position and connected when the second module is in the second position.

[0022] As an example, the first module includes a first docking component, and the second module includes a second docking component, wherein the first docking component and the second docking component remain connected as the second module moves between the first position and the second position;

[0023] Wherein, the interference force between the first docking component and the second docking component is less than the interference force between the first module and the third module, such that when the second module moves between the first position and the second position, the first module and the third module remain relatively stationary.

[0024] As an example, the interference force between the first docking component and the second docking component is greater than the gravity of the second module, so that the second module can be held in the first position.

[0025] As an example, the second module includes a flow guide column facing away from the second chamber, and the fluid channel includes a first flow guide hole formed on the side wall of the flow guide column and a second flow guide hole disposed inside the flow guide column and in fluid communication with the second chamber.

[0026] As an example, the first module includes a flexible plug, on which a first mating hole is formed;

[0027] The first convex ring is present on either the wall of the first docking hole or the outer wall of the guide column.

[0028] When the second module is in the first position, the first flow guide hole and the first chamber are located on opposite sides of the first convex ring, and the first convex ring provides a sealing connection between the flexible plug and the flow guide post. When the second module is in the second position, a portion of the flow guide post protrudes through the first docking hole and exposes the first flow guide hole outside the first docking hole.

[0029] As an example, a second protruding ring is provided on either the wall of the first docking hole or the outer wall of the guide post. The second protruding ring is located between the first guide hole and the second chamber, and provides a sealing connection between the flexible plug and the guide post when the second module moves between the first position and the second position.

[0030] As an example, the first module includes a cup body and a fibrous element disposed within the first chamber for holding a liquid matrix, the cup body defining at least a portion of the boundary of the first chamber;

[0031] The second module includes a flow guide column, and at least one of the fluid channels includes a first flow guide hole formed on the wall of the flow guide column and a second flow guide hole disposed inside the flow guide column and in fluid communication with the second chamber;

[0032] When the second module is in the second position, the first flow guide hole is located in the cup body and is spaced apart from the fiber element.

[0033] As an example, the cup body has a second docking hole that connects to the first chamber, and the wall of the second docking hole has a protrusion.

[0034] When the second module is in the second position, the protrusion abuts against the guide post, so that there is a gap between the hole wall of the second docking hole and the guide post that connects to the first chamber, and the first guide hole is located in the second docking hole and is set corresponding to the gap.

[0035] As an example, the first module includes a cup body that defines at least a portion of the boundary of the first chamber, and the second module includes a shell that defines at least a portion of the boundary of the second chamber;

[0036] One of the cup body and the shell is provided with a first stop edge and a second stop edge, and the other is provided with a fastening element;

[0037] After the second module is connected to the first module, the latching member is located between the first stop edge and the second stop edge, and when the second module moves between the first position and the second position, the latching member moves between the first stop edge and the second stop edge;

[0038] The second module is configured to disengage from the third module by acting on the latching member through the first stop edge.

[0039] As an example, the first module has an air guide tube and an auxiliary air channel, the air guide tube being connected to the air guide tube of the atomizing core to guide the aerosol;

[0040] The auxiliary airway connects the first chamber and the air delivery tube to balance the air pressure in the first chamber and the air delivery tube.

[0041] As an example, the second module includes a suction nozzle.

[0042] The aerosol generating device provided in the above embodiments includes a first module, a second module, and a third module. The first module includes a first chamber for storing a liquid matrix and an atomizing core for atomizing the liquid matrix to generate aerosol. The first chamber and the atomizing core are in fluid communication, and the first module has a first end and a second end disposed opposite to each other. The second module has a second chamber for storing a liquid matrix inside. The second module is independent of the first module and can be connected to the first end of the first module. When the second module and the first module are connected, a fluid channel for replenishing the liquid matrix from the second chamber to the first chamber can be established between them. The third module is detachably connected to the second end of the first module. The third module includes a power supply. The power supply is used to establish a power supply path between the third module and the atomizing core when the third module and the first module are connected. The second module is configured to provide user operation to establish a connection with the first module and to drive the first module to detach from the third module. Therefore, users can not only choose to connect the second module to the first module, but also operate the second module to detach the first module from the third module when the second module needs to be replaced, so that the first module and the second module can be replaced at the same time, and the atomizing core in the first module can maintain the desired effect.

[0057] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection 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.

[0060] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be intervening elements. When an element is referred to as being "connected to" another element, it can be directly connected to the other element, or there may be one or more intervening elements.

[0061] Referring to Figures 1-9, some embodiments of this application provide an aerosol generating device. The aerosol generating device includes a first module 1, a second module 2, and a third module 3, which are independent of each other. The second module 2 is assembled and connected to a first end of the first module 1, and the third module 3 is assembled and connected to a second end of the first module 1. The first end and the second end can be arranged opposite to each other, so that the first module 1, the second module 2, and the third module 3 can be arranged longitudinally. Of course, the first end and the second end can also be located on two adjacent sides of the first module 1.

[0062] The first module 1 includes a first chamber 111 and an atomizing core 12 capable of atomizing a liquid matrix to form an aerosol, wherein the first chamber 111 and the atomizing core 12 are in fluid communication; the second module 2 includes a second chamber 211 having an internal storage for storing a liquid matrix, wherein after the first module 1 and the second module 2 are connected, a fluid channel is formed between the second module 2 and the first module 1 for fluid communication between the first chamber 111 and the second chamber 211; the third module 3 includes a power supply 31 for providing power to the atomizing core 12 for atomizing the liquid matrix.

[0063] The liquid matrix can contain a liquid containing tobacco-based substances with volatile tobacco aroma components, or it can contain a liquid containing non-tobacco substances. The liquid matrix can contain water, pharmaceutical solutions, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures, etc. Fragrances can include areca nut extract, menthol, peppermint, spearmint oil, various fruit flavorings, etc., but are not limited to these. Flavorings can contain ingredients that can provide users with various fragrances or flavors. Vitamin mixtures can be mixtures containing at least one of vitamins A, B, C, and E, but are not limited to these. Based on the different properties of the liquid matrix, aerosol generating devices can be used in different fields, such as medical and electronic aerosol atomization.

[0064] In some embodiments, the atomizing core 12 includes a liquid-absorbing element and a heating element, the heating element being disposed on the liquid-absorbing element. The liquid-absorbing element can be a porous body for guiding the liquid matrix into the atomization range of the heating element. The heating element is used to heat the atomized aerosol matrix, thereby generating an aerosol. The porous body can be a fiber, such as cotton fiber, polypropylene fiber, polyester fiber, or nylon fiber. The porous body can be porous ceramic or porous metal; this application does not limit the structure and composition of the porous body.

[0065] In some embodiments, the atomizing core 12 may include an ultrasonic element capable of generating ultrasonic waves, which atomizes the liquid matrix to form an aerosol. Of course, the atomizing core 12 may also include other elements capable of atomizing the liquid matrix to form an aerosol.

[0066] In some embodiments, the first chamber 111 can store a liquid matrix, and the amount of liquid matrix stored may be less than or equal to 2 ml, but is not limited thereto; the liquid matrix in the second chamber 211 can enter the first chamber 111 to supply liquid matrix to the first chamber 111. In other embodiments, the first chamber 111 is mainly used to guide the liquid matrix in the second chamber 211 to the atomizing core 12 for atomization.

[0067] To prevent leakage from the first module 1, the first module 1 further includes a fiber element 13 disposed in the first chamber 111, capable of adsorbing the liquid matrix and retaining at least a portion of the adsorbed liquid matrix. The fiber element 13 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.

[0068] Referring to Figures 5, 6, and 10-12, the first module 1 also includes a cup body 11, which defines at least a portion of the boundary of the first chamber 111. The fiber element 13 is housed within the cup body 11. An air-guiding channel 15 can be formed between the fiber element 13 and the cup body 11 by constructing the outer surface of the fiber element 13 or the inner wall of the cup body 11. This air-guiding channel 15 connects the two opposite ends of the fiber element 13 in the longitudinal direction. On the one hand, the air-guiding channel 15 can ensure a uniform air pressure distribution in the first chamber 111, allowing the liquid matrix in the fiber element 13 to be smoothly transported towards the atomizing core 12. On the other hand, it can provide clearance for the expanded fiber element 13, liquid matrix, and gas when the fiber element 13, the gas in the first chamber 111, and the liquid matrix expand due to heat or under the pressure difference between the inside and outside of the first chamber 111, preventing the liquid matrix from leaking out of the first chamber 111.

[0069] In the embodiment shown in Figure 12, the sidewall of the fiber element 13 has strip-shaped ribs 131, which abut against the inner wall of the cup body 11, thereby creating the air guiding channel 15 between the other part of the sidewall of the fiber element 13 and the inner wall of the cup body 11, or creating the air guiding channel 15 between two adjacent strip-shaped ribs 131. The strip-shaped ribs 131 can extend longitudinally to connect two oppositely arranged end faces of the fiber element 13.

[0070] The first module 1 may further include an air guide tube that communicates with the atomizing core 12 for guiding the aerosol generated by the atomizing core 12 outside the first module 1. The air guide tube may pass through the first chamber 111, and the fiber element 13 may be arranged around the air guide tube. In one example, the atomizing core 12 may be disposed in the air guide tube.

[0071] In some embodiments, the capacity of the second chamber 211 is greater than that of the first chamber 111. The second chamber 211 can store a liquid matrix of less than or equal to 10 ml, but is not limited thereto. The liquid matrix stored in the second chamber 211 may have the same flavor as the liquid matrix stored in the first chamber 111, or it may have a different flavor. Referring to Figures 5 and 6, the second module 2 includes a housing 21 that defines at least a portion of the boundary of the second chamber 211.

[0072] When the second module 2 is connected to the first module 1, a fluid channel can be established between the second module 2 and the first module 1 to replenish the liquid matrix from the second chamber 211 to the first chamber 111. When the first module 1 and the third module 3 are connected, a power supply path is established between the power supply 31 and the atomizing core 12.

[0073] It should be noted that the first module 1 and the second module 2 are independent of each other, meaning that the first module 1 and the second module 2 need to be assembled together under the user's operation. Therefore, the user can choose the second module 2 connected to the first module 1. Different second modules 2 can be different; for example, the second chamber 211 in different second modules 2 can have different capacities, or the second chamber 211 in different second modules 2 can store liquid bases of different flavors; of course, different second modules 2 can also be completely identical.

[0074] Similarly, the third module 3 and the first module 1 are independent of each other, so that the first module 1 and the third module 3 can be assembled together under the user's operation.

[0075] The second module 2 is configured to be operable so that it can be connected to the first module 1. The user can also operate the second module 2 to drive the first module 1 and detach it from the third module 3. The second module 2 and the first module 1 can therefore be removed and replaced together.

[0076] In some embodiments, the aerosol generating apparatus further includes a fourth module, wherein a first end of the first module 1 is configured to be detachably connected to the fourth module, and the first end of the first module 1 is exposed after the fourth module is removed for connection to the second module 2.

[0077] In other words, in the initial state of the aerosol generating device, the fourth module is detachably connected to the first end of the first module 1. When the aerosol generating device needs to be used, or when the liquid matrix needs to be supplied to the first chamber 111, the fourth module is first removed from the first module 1, and then the second module 2 is connected to the first end in place of the fourth module.

[0078] When the fourth module is connected to the first module 1, it can seal the first chamber 111 to prevent the liquid matrix in the first chamber 111 from leaking through the first end.

[0079] In some embodiments, as shown in Figures 5 and 6, the second module 2 further includes a suction nozzle 22. The suction nozzle 22 can be integrally formed with the housing 21, or the suction nozzle 22 can be fixed on the housing 21. The suction nozzle 22 is used for the user's mouth to hold. The suction nozzle 22 has an air intake 221. The user sucks in the aerosol generated by the first module 1 by sucking in the air intake 221. Therefore, the air intake 221 is in fluid communication with the air guide tube in the first module 1.

[0080] Based on this, when the fourth module is connected to the first module 1, it can keep the air duct clean and reduce air convection between the first module 1 and the outside, which is beneficial for preventing leakage and deterioration of the liquid matrix in the first chamber 111. In some embodiments, the fourth module can also seal the air duct, thereby preventing the air pressure inside the first module 1 from being affected by the external air pressure, which helps to prevent the fiber element 13 in the first chamber 111 from expanding and prevent the liquid matrix in the first chamber 111 from leaking; for example, when the air pressure around the aerosol generating device decreases in the initial state, it can prevent the liquid matrix in the first chamber 111 from automatically flowing out.

[0081] In some embodiments, the second module 2 and the first module 1 are not detachable after being connected, making it impossible or difficult to separate the two modules after they are connected. Of course, the connection between the second module 2 and the first module 1 can also be detachable, so that the two modules can be separated from each other by appropriate operation or tools after they are connected.

[0082] In some embodiments, the connection between the second module 2 and the first module 1 is detachable. However, the method of detachment after the second module 2 is connected to the first module 1 differs from the method of detachment after the third module 3 is connected to the first module 1, or the detachment force after the second module 2 is connected to the first module 1 is greater than the detachment force after the third module 3 is connected to the first module 1. Therefore, during the process of the second module 2 driving the first module 1 to detach from the third module 3, the second module 2 and the first module 1 can maintain their connection. In this embodiment, the fourth module is optional rather than mandatory.

[0083] Specifically, in one embodiment, the disassembly method of the second module 2 after it is connected to the first module 1 is different from the disassembly method of the third module 3 after it is connected to the first module 1. This includes a difference in the connection method between the second module 2 and the first module 1 compared to the connection method between the third module 3 and the first module 1. For example, the second module 2 and the first module 1 are connected by a snap-fit ​​connection, while the third module 3 and the first module 1 are connected by a magnetic attraction connection. Referring to Figures 2-5, the first module 1 further includes a first magnetic component 16, and the third module 3 further includes a second magnetic component 33. When the first magnetic component 16 and the second magnetic component 33 are brought close together, they have a magnetic attraction force, ensuring a stable connection between the first module 1 and the third module 3. Referring to Figures 2 and 3, one of the first module 1 and the second module 2 has a first stop edge 231 and a second stop edge 232, while the other has a latching member 112. After the second module 2 is connected to the first end of the first module 1, the latching member 112 is located between the first stop edge 231 and the second stop edge 232. The second module 2 is configured to drive the first module 1 to disengage from the third module 3 by the first stop edge 231 acting on the latching member 112. In the embodiment shown in Figures 2 and 3, the housing 21 is provided with a latching groove 23. The first stop edge 231 and the second stop edge 232 are arranged opposite to each other and define part of the boundary of the latching groove 23. The cup body 11 is provided with a spring arm 113 and a latching member 112 provided on the spring arm 113. When the spring arm 113 is deformed by pressing it laterally, the latching member 112 can be disengaged from the latching groove 23. Then, when a longitudinal force is applied, the second module 2 can disengage from the first module 1. Of course, the first stop edge 231 and the second stop edge 232 can also be components of the cup body 11, and the buckle 112 and the spring arm 113 can therefore be components of the housing 21.

[0084] In one embodiment, the method of disassembling the second module 2 after it is connected to the first module 1 is different from the method of disassembling the third module 3 after it is connected to the first module 1. This includes that the direction of disassembly of the second module 2 after it is connected to the first module 1 is different from the direction of disassembly of the third module 3 after it is connected to the first module 1. For example, when the first module 1 is moved longitudinally in a direction away from the third module 3, the first module 1 can detach from the third module 3. However, the second module 2 needs to be rotated relative to the first module 1 in a preset direction to detach from the first module 1.

[0085] In some embodiments, the disassembly force after the second module 2 is connected to the first module 1 is greater than the disassembly force after the third module 3 is connected to the first module 1. When the second module 2 and the first module 1 are connected, they interfere with each other, thus maintaining a stable connection. When the second module 2 needs to be removed from the first module 1, the disassembly force must overcome the interference force between the second module 2 and the first module 1. Similarly, when the first module 1 needs to be removed from the third module 3, the disassembly force must overcome the interference force between the third module 3 and the first module 1. Therefore, when a force is applied along the direction that separates the first module 1 and the third module 3, the separation of the first module 1 and the third module 3 occurs before the separation of the second module 2 and the first module 1. Furthermore, when the first module 1 and the third module 3 separate, the first module 1 and the second module 2 can remain connected. In this embodiment, the connection method between the second module 2 and the first module 1 can be the same as the connection method between the third module 3 and the first module 1, and / or the disassembly direction after the second module 2 is connected to the first module 1 can be the same as the disassembly direction after the third module 3 is connected to the first module 1.

[0086] The fluid passage between the second chamber 211 of the second module 2 and the first chamber 111 of the first module 1 can be mainly opened when the user uses the aerosol generating device, and disconnected when the user puts the aerosol generating device down.

[0087] Based on this, in some embodiments, referring to Figures 5 and 6, the second module 2 is configured to be movable relative to the first module 1 between a first position and a second position; wherein the fluid passage between the second chamber 211 and the first chamber 111 is disconnected when the second module 2 is in the first position and connected when the second module 2 is in the second position. Preferably, the second module 2 moves longitudinally between the first position and the second position, but is not limited thereto.

[0088] Further, referring to Figures 5 and 6, the first end of the first module 1 has a first docking component 14, and the second module has a second docking component 24. During the movement of the second module 2 between the first position and the second position, the first docking component 14 and the second docking component 24 remain connected, thereby maintaining mutual interference. The interference force between the first docking component 14 and the second docking component 24 is less than the interference force between the first module 1 and the third module 3, so that when the second module 2 moves between the first position and the second position, the first module 1 and the third module 3 remain relatively stationary. Thus, during the process of the fluid channel between the second chamber 211 and the first chamber 111 switching from disconnected to open, or from open to disconnected, the first module 1 and the third module 3 remain relatively stationary.

[0089] Furthermore, since the first module 1 and the second module 2 are arranged longitudinally, and the second module 2 is located above the first module 1 longitudinally, when the first module 1 and the second module 2 are connected, the first module 1 needs to provide an upward force to overcome the gravity of the second module 2 and support the second module 2.

[0090] The first position is located vertically above the second position. When the second module 2 is in the first position, the interference force between the first docking component 14 and the second docking component 24 is greater than the gravity of the second module 2, so that the second module 2 can be maintained in the first position, so that the fluid channel between the second chamber 211 and the first chamber 111 remains disconnected, and prevents the fluid channel between the second chamber 211 and the first chamber 111 from automatically opening.

[0091] In this application, there may be at least one fluid channel between the second chamber 211 and the first chamber 111. In the embodiments shown in FIG5 and FIG6, there are two fluid channels between the second chamber 211 and the first chamber 111.

[0092] In some embodiments, at least one fluid channel is configured to provide a liquid path for the liquid matrix in the second chamber 211 to flow into the first chamber 111, wherein the liquid path is configured to disconnect when the air pressure in the second chamber 211 is lower than the air pressure in the first chamber 111; at least one fluid channel is configured to provide an air path for guiding air communication between the second chamber 211 and the first chamber 111, such that the air pressure between the second chamber 211 and the first chamber 111 is balanced, wherein the air path is disconnected when the second module 2 is in a first position and connected when the second module 2 is in a second position.

[0093] To simplify the structure, the liquid path and the gas path can overlap at least partially, with at least partially allowing gas flow through the liquid path or at least partially allowing the liquid matrix to flow through the gas path. Of course, the liquid path and the gas path can also be independent of each other.

[0094] In some embodiments, referring to Figures 5 and 6, the first docking assembly 14 includes a flexible plug 141 made of a flexible material, such as silicone. The flexible plug 141 has a first docking hole 1411, and the wall of the first docking hole 1411 has a first protruding ring 1412. The second docking assembly 24 includes a flow guide column 241. At least one fluid channel includes a first flow guide hole 2411 formed on the sidewall of the flow guide column 241 and a second flow guide hole 2412 disposed inside the flow guide column 241 and in fluid communication with the second chamber 211. Referring to Figure 5, when the second module 2 is in the first position, the first flow guide hole 2411 and the first chamber 111 are located on opposite sides of the first protruding ring 1412, and the first protruding ring 1412 provides a sealing connection between the flexible plug 141 and the flow guide column 241, thus isolating the first chamber 111 from the first flow guide hole 2411, thereby disconnecting the gas path and the liquid path. Referring to Figure 6, when the second module 2 is in the second position, the first guide hole 2411 extends out of the first docking hole 1411 and is located outside the first docking hole 1411, thus connecting the gas path and the liquid path.

[0095] In the embodiments shown in Figures 5, 6, and 8, the wall of the first mating hole 1411 may also have a second protruding ring 1413. When the second module 2 is in the first position, the first guide hole 2411 is located between the first protruding ring 1412 and the second protruding ring 1413, and the second protruding ring 1413 is located between the second chamber 211 and the first guide hole 2411. The second protruding ring 1413 provides a sealing connection between the flexible plug 141 and the guide column 241 to prevent the liquid matrix in the second chamber 211 from leaking through the first guide hole 2411. When the second module 2 is in the second position, the first protruding ring 1412 and the second protruding ring 1413 are located on the same side of the first guide hole 2411, and the second protruding ring 1413 still provides a sealing connection between the flexible plug 141 and the guide column 241 to prevent the liquid matrix in the second chamber 211 from leaking through the first guide hole 2411.

[0096] It should be noted that, in other embodiments, the first convex ring 1412 and / or the second convex ring 1413 may be disposed on the outer wall of the guide column 241.

[0097] In the embodiments shown in Figures 5 and 6, the first docking assembly 14 further includes a first retainer 142. The first retainer 142 connects the flexible plug 141 and the cup body 11, with at least a portion of the flexible plug 141 located between the first retainer 142 and the cup body 11. The first retainer 142 serves to maintain the connection between the flexible plug 141 and the cup body 11 and to prevent longitudinal displacement of the flexible plug 141 relative to the cup body 11. When the second module 2 is connected to the first module 1, the first retainer 142 supports the second module 2.

[0098] The second docking assembly 24 may further include a second retainer 242 and a sealing plug 243, the sealing plug 243 being made of a flexible material, such as silicone. The hardness of the second retainer 242 is greater than that of the sealing plug 243. At least a portion of the sealing plug 243 is disposed between the housing 21 and the second retainer 242 to provide a seal between the housing 21 and the second retainer 242, and the second retainer 242 and the sealing plug 243 cooperate to seal the end of the second chamber 211 facing the first module 1. The flow guide 241 and the second retainer 242 may be integrally formed, or the flow guide 241 may be disposed on the second retainer 242.

[0099] In some embodiments, referring to FIG6, when the second module 2 is in the second position, the first guide hole 2411 is located in the cup body 11 and is spaced apart from the fiber element 13 to prevent the fiber element 13 from blocking the first guide hole 2411, thereby affecting the air guiding column 241 and the air passage. Of course, when the second module 2 is in the second position, the end of the guide column 241 can abut against the fiber element 13.

[0100] Please refer to Figures 5, 6 and 10. The cup body 11 has a second docking hole 114 that connects to the first chamber 111. When the second module 2 is in the second position, the first guide hole 2411 can be located in the second docking hole 114, and the first guide hole 2411 is spaced apart from the hole wall of the second docking hole 114, so that the first guide hole 2411 is connected to the first chamber 111 for air conduction.

[0101] To prevent the guide column 241 from being tilted relative to the second docking hole 114 when the second module 2 is in the second position, causing the hole wall of the second docking hole 114 to block the first guide hole 2411, please refer to Figures 5 and 10. The hole wall of the second docking hole 114 may have a protrusion 115. When the second module 2 is in the second position, the protrusion 115 abuts against the guide column 241, so that there is a gap between the hole wall of the second docking hole 114 and the guide column 241 that connects to the first chamber 111.

[0102] The protrusion 115 can be a strip extending longitudinally. Preferably, the length of the strip-shaped protrusion 115 is less than the depth of the second docking hole 114 to reduce the resistance to the movement of the guide column 241 in the second docking hole 114. There can be multiple protrusions 115, and the multiple protrusions 115 are evenly distributed along the hole wall of the second docking hole 114, which helps to make the central axis of the guide column 241 coincide with the central axis of the second docking hole 114.

[0103] Referring to Figures 5 and 6, the second docking hole 114 is set corresponding to the first docking hole 1411, and the central axis of the second docking hole 114 and the central axis of the first docking hole 1411 can coincide. The diameter of the second docking hole 114 is larger than the outer diameter of the guide column 241. The diameter of the second docking hole 114 can be larger than the diameter of the first docking hole 1411.

[0104] In some embodiments, as shown in FIG11, the first module 1 has an auxiliary airway 17, which guides air to connect the first chamber 111 and the air guide tube, so as to balance the air pressure in the first chamber 111 and the air guide tube, thereby preventing leakage of the liquid matrix in the first chamber 111.

[0105] Referring to Figures 8 and 10, the cup body 11 is provided with a fixing hole 116 and a through hole 117 for fluid communication with the first chamber 111. The flexible plug 141 has a tubular portion 1415 with a notch 1414 on its sidewall. The air guide tube communicates with the tubular portion 1415. At least a portion of the tubular portion 1415 is embedded in the fixing hole 116 and held in place. The notch 1414 on the tubular portion 1415 is a component of the auxiliary airway 17. Specifically, at least a portion of the tubular portion 1415 is embedded in the fixing hole 116 of the cup body 11 and held in place.

[0106] The flexible plug 141 is partially disposed on the surface of the cup body 11 facing the second module 2, and a guide groove 118 is formed on the surface of the cup body 11 facing the second module 2. One end of the guide groove 118 is connected to the through hole 117, and the other end of the guide groove 118 extends to the connecting fixing hole 116, and then connects to the notch 1414 on the tubular part 1415. The guide groove 118 and the through hole 117 are also components of the auxiliary air passage 17.

[0107] Therefore, when the air pressure in the first chamber 111 is greater than the air pressure in the air duct, the gas in the first chamber 111 sequentially enters the tubular portion 1415 through the through hole 117, the guide groove 118, and the notch 1414, and then enters the air duct or the second module 2 / fourth module. When the air pressure in the first chamber 111 is less than the air pressure in the air duct, the gas in the second module 2 / fourth module or the air duct can first enter the tubular portion 1415, and then sequentially flow into the first chamber 111 through the notch 1414, the guide groove 118, and the through hole 117. Therefore, the air pressure balance between the first chamber 111 and the air duct can be maintained. Since the second chamber 211 is connected to the first chamber 111 by airflow, the second chamber 211 can also be basically balanced with the air pressure in the air duct when the air path is open.

[0108] In some embodiments, referring to Figures 4-6, the third module 3 further includes a proximal open housing 32, with a receiving cavity 321 inside the housing 32, the receiving cavity 321 being disposed adjacent to the proximal end of the housing 32; wherein, the first module 1 is removably held in the receiving cavity 321, and a portion of the second module 2 is removably held in the receiving cavity 321, partially exposed outside the housing 32 for user operation. The user can separate and detach the first module 1, which is completely covered by the housing 32, from the third module 3 and remove it from the receiving cavity 321 by operating the portion of the second module 2 exposed outside the housing 32.

[0109] Please refer to Figures 2-4. The first module 1 also includes a first electrode 18 electrically connected to the atomizing core 12. The first electrode 18 is fixed on the bottom of the first module 1. The third module 3 also includes a second electrode 34 electrically connected to the power supply 31. When the first module 1 and the third module 3 are connected, the first electrode 18 abuts against the second electrode 34 and the first electrode 18 and the second electrode 34 remain electrically connected.

[0110] In some embodiments, a vent 19 fluidly communicating with the atomizing core 12 is provided on the bottom of the first module 1. An air inlet 212 of the aerosol generating device is provided on the outer casing 32, and the air inlet 212 fluidly communicates with the vent 19 of the first module 1. Outside air enters the interior of the outer casing 32 through the air inlet 212, then enters the first module 1 through the vent 19, and combines with the liquid matrix to form a mist under the action of the atomizing core 12, thus forming an aerosol. A regulating valve 213 may be provided on the outer casing 32 to regulate the amount of air entering the outer casing 32 through the air inlet 212, thereby adjusting the suction resistance of the aerosol generating device.

[0111] In some embodiments, referring to Figures 5 and 6, the second module 2 further includes a connecting pipe 25 with an internal air passage. The connecting pipe 25 is disposed inside the housing 21, and one end of the connecting pipe 25 is connected to the air intake 221, while the other end passes through the second docking assembly 24 and is exposed to the outside to dock with the first docking assembly 14.

[0112] The connecting pipe 25 is press-fitted with the sealing plug 243 when passing through the second docking assembly 24, so that the two are sealed to prevent leakage of the liquid matrix in the second chamber 211.

[0113] The flexible plug 141 has a mating hole 1416 that corresponds to and communicates with the tubular portion 1415. When the second module 2 is connected to the first module 1, the end of the connecting tube 25 is embedded in the mating hole 1416 of the flexible plug 141 and is press-fitted with the mating hole 1416 to make the two connected in a sealed manner to prevent aerosol leakage.

[0114] To prevent the large accumulation of condensate formed by aerosols on the inner wall of the connecting tube 25, which could cause the user to inhale the condensate into their mouth when drawing air into the inhalation port 221, a strip-shaped groove 251 is provided on the inner wall of the connecting tube 25, extending to the distal end of the connecting tube 25. This groove guides the condensate in the connecting tube 25 into the tubular portion 1415, allowing it to flow onto the atomizing core 12 and then into the first chamber 111 along the auxiliary air passage 17. The extension length of the strip-shaped groove 251 can be greater than or equal to half the length of the connecting tube 25, or less than or equal to four-fifths of the length of the connecting tube 25; no specific limitation is made here.

[0115] 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.
