Description

TECHNICAL FIELD

[0001] This application relates to the field of aerosol generation technologies, and in particular, to an aerosol generation device. BACKGROUND

[0002] An aerosol generation device is a device capable of atomizing a liquid formulation to form an aerosol. However, in some exemplary prior arts, there is an aerosol generation device that includes an atomizer, a backup oil storage chamber, and a power supply assembly. The backup oil storage chamber is in communication with the atomizer through a liquid path, to supply a liquid substrate to an oil chamber in the atomizer. The power supply assembly is connected to the atomizer through a circuit, to provide, through the circuit, the atomizer with power for atomizing the liquid substrate. The backup oil storage chamber is detachably connected to the atomizer, to replace the backup oil storage chamber after the liquid substrate in the backup oil storage chamber is exhausted.

[0003] However, an atomization core configured to atomize the liquid substrate in the existing atomizer has a limited amount of atomization. A combined amount of a liquid substrate reserve in the backup oil storage chamber and a liquid substrate reserve in the atomizer has substantially reached an upper limit of atomization amount of the atomization core. When the liquid substrate in the backup oil chamber is exhausted, the remaining lifespan of the atomization core is insufficient to continue atomizing a liquid substrate in a new backup oil chamber according to an expected effect, which not only causes waste after replacing the new backup oil chamber, but also reduces user experience. SUMMARY

[0004] An objective of this application is to provide an aerosol generation device, which not only can enable independence between a first module and a second module, but also can enable the first module including an atomization core to be separated from a third module when replacing the second module. This enables simultaneous replacement of the first module and the second module, so that the aerosol generation device provides user experience meeting expectations during repeated use.

[0005] At least one embodiment of this application provides an aerosol generation device. The aerosol generation device includes:

[0006] a first module, including a first chamber configured to store a liquid substrate and an atomization core configured to atomize the liquid substrate to generate an aerosol, where the first chamber is in fluid communication with the atomization core, and the first module includes a first end and a second end that are opposite to each other;

[0007] a second module, internally including a second chamber configured to store a liquid substrate, where the second module is independent of the first module and is connected to the first end of the first module, and when the second module and the first module are in a connected state, a fluid channel for supplementing the liquid substrate from the second chamber to the first chamber is established between the second module and the first module; and

[0008] a third module, detachably connected to the second end of the first module, where the third module includes a power supply, and the power supply is configured to establish a power supplying path between the power supply and the atomization core when the third module and the first module are in the connected state, where

[0009] the second module is configured to be operable by a user to establish a connection to the first module, and drive the first module to be separated from the third module.

[0010] As an example, the second module and the first module are not detachable from each other after the connection is established.

[0011] As an example, the connection between the second module and the first module is a detachable connection, where

[0012] a disassembly manner after the second module is connected to the first module is different from a disassembly manner after the third module is connected to the first module; or

[0013] a disassembly force after the second module is connected to the first module is greater than a disassembly force after the third module is connected to the first module.

[0014] As an example, the third module further includes a shell having an open proximal end, and an interior of the shell includes an accommodating cavity adjacent to the proximal end of the shell, where

[0015] the first module is removably retained in the accommodating cavity, the second module is partially removably retained in the accommodating cavity, and partially exposed outside the shell for the user to operate.

[0016] As an example, the aerosol generation device further includes a fourth module, and the fourth module is configured to be partially accommodated in the accommodating cavity and expose the first end of the first module after being removed from the accommodating cavity.

[0017] As an example, the second module is configured to move relative to the first module between a first position and a second position, where

[0018] the fluid channel is disconnected when the second module is located at the first position, and the fluid channel is connected when the second module is located at the second position.

[0019] As an example, the first module includes a first docking assembly, the second module includes a second docking assembly, and when the second module moves between the first position and the second position, the first docking assembly retains connected to the second docking assembly, where

[0020] an interference force between the first docking assembly and the second docking assembly is less than an interference force between the first module and the third module, and when the second module moves between the first position and the second position, the first module remains relatively stationary with the third module.

[0021] As an example, the interference force between the first docking assembly and the second docking assembly is greater than a gravitational force of the second module, so that the second module remains at the first position.

[0022] 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 provided on a side wall of the flow guide column and a second flow guide hole provided inside the flow guide column and in fluid communication with the second chamber.

[0023] As an example, the first module includes a flexible plug, and the flexible plug is provided with a first docking hole, where

[0024] a first convex ring is provided on one of a hole wall of the first docking hole and an outer wall of the flow guide column; and

[0025] when the second module is located at the first position, the first flow guide hole and the first chamber are located at two opposite sides of the first convex ring and the first convex ring provides a sealing connection between the flexible plug and the flow guide column, and when the second module is located at the second position, the flow guide column partially passes through the first docking hole and exposes the first flow guide hole out of the first docking hole.

[0026] As an example, a second convex ring is provided on one of the hole wall of the first docking hole and the outer wall of the flow guide column, the second convex ring is located between the first flow guide hole and the second chamber, and when the second module moves between the first position and the second position, the second convex ring provides a sealing connection between the flexible plug and the flow guide column.

[0027] As an example, the first module includes a cup body and a fiber element that is arranged in the first chamber and configured to hold the liquid substrate, and the cup body defines at least part of a boundary of the first chamber;

[0028] the second module includes a flow guide column, and at least one fluid channel includes a first flow guide hole provided on a wall of the flow guide column and a second flow guide hole provided inside the flow guide column and in fluid communication with the second chamber; and

[0029] when the second module is located at the second position, the first flow guide hole is located in the cup body and is spaced apart from the fiber element.

[0030] As an example, a wall of the cup body is provided with a second docking hole in communication with the first chamber, and a hole wall of the second docking hole is provided with a protrusion; and

[0031] when the second module is located at the second position, the protrusion abuts against the flow guide column, forming a gap in communication with the first chamber between the hole wall of the second docking hole and the flow guide column, and the first flow guide hole is located in the second docking hole and is arranged corresponding to the gap.

[0032] As an example, the first module includes the cup body defining at least the part of the boundary of the first chamber, and the second module includes a housing defining at least part of a boundary of the second chamber;

[0033] one of the cup body and the housing is provided with a first stopping edge and a second stopping edge, and the other is provided with a buckling member; and

[0034] after the second module is connected to the first module, the buckling member is located between the first stopping edge and the second stopping edge, and when the second module moves between the first position and the second position, the buckling member moves between the first stopping edge and the second stopping edge, where

[0035] the second module is configured to act on the buckling member through the first stopping edge, to drive the first module to be separated from the third module.

[0036] As an example, the first module includes an air guide tube and an auxiliary air channel, and the air guide tube is in air communication with the atomization core, to guide the aerosol; and

[0037] the auxiliary air channel enables air communication between the first chamber and the air guide tube, to balance air pressure in the first chamber and the air guide tube.

[0038] As an example, the second module includes a suction nozzle.

[0039] The aerosol generation device provided in the foregoing embodiment includes a first module, a second module, and a third module. The first module includes a first chamber configured to store a liquid substrate and an atomization core configured to atomize the liquid substrate to generate an aerosol, where the first chamber is in fluid communication with the atomization core, and the first module includes a first end and a second end that are opposite to each other. The second module internally includes a second chamber configured to store a liquid substrate, where the second module is independent of the first module and is connected to the first end of the first module, and when the second module and the first module are in a connected state, a fluid channel for supplementing the liquid substrate from the second chamber to the first chamber is established between the second module and the first module. The third module is detachably connected to the second end of the first module, where the third module includes a power supply, and the power supply is configured to establish a power supplying path between the power supply and the atomization core when the third module and the first module are in the connected state. The second module is configured to be operable by a user to establish a connection to the first module, and drive the first module to be separated from the third module. Therefore, the user not only can select the second module to connect to the first module, but also can operate the second module to drive the first module to be separated from the third module when the second module needs to be replaced. This enables simultaneous replacement of the first module and the second module, so that the atomization core in the first module can operate with an expected effect.

[0058] Referring to FIG. 1 to FIG. 9, some embodiments of this application provide an aerosol generation device. The aerosol generation device includes a first module 1, a second module 2, and a third module 3 that are independent of each other. The second module 2 is connected to a first end of the first module 1 through assembly, the third module 3 is connected to a second end of the first module 1 through assembly. The first end and the second end may be arranged opposite to each other, enabling the first module 1, the second module 2, and the third module 3 to be arranged longitudinally. Certainly, the first end and the second end may alternatively be located on two adjacent sides of the first module 1.

[0059] The first module 1 includes a first chamber 111 and an atomization core 12 capable of atomizing a liquid substrate to form an aerosol, and the first chamber 111 is in fluid communication with the atomization core 12; the second module 2 internally includes a second chamber 211 configured to store a liquid substrate, and after the first module 1 is connected to the second module 2, a fluid channel configured to fluid communicate the first chamber 111 and the second chamber 211 is formed between the second module 2 and the first module 1; and the third module 3 includes a power supply 31, and the power supply 31 is configured to provide the atomization core 12 with power for atomizing the liquid substrate.

[0060] The liquid substrate may include a liquid including a tobacco-containing substance having a volatile tobacco-flavor component, and may further include a liquid including a non-tobacco substance. The liquid substrate may contain water, medicinal liquid, solvent, ethanol, plant extract, fragrance, a flavoring agent, vitamin mixture, or the like. The fragrance may include, but is not limited to, areca nut extract, menthol, peppermint, spearmint oil, various fruit fragrance components, and the like. The flavoring agent may include components that can provide various fragrances or flavors to a user. The vitamin mixture may be a mixture having at least one of vitamin A, vitamin B, vitamin C, and vitamin E mixed therein, but is not limited thereto. Based on different attributes of the liquid substrate, the aerosol generation device may be used in different fields, such as medical treatment and electronic aerosol atomization.

[0061] In some embodiments, the atomization core 12 includes a liquid absorbing element and a heating element, and the heating element is arranged on the liquid absorbing element. The liquid absorbing element may be a porous body, and is configured to guide the liquid substrate into an atomization range of the heating element. The heating element is configured to heat and atomize the liquid substrate, to generate the aerosol. The porous body may be a fiber, such as a cotton fiber, a polypropylene fiber, a polyester fiber, or a nylon fiber. The porous body may be a porous ceramic or a porous metal. A structure and composition of the porous body are not limited in this application.

[0062] In some embodiments, the atomization core 12 may include an ultrasonic element capable of generating an ultrasonic wave, and the atomization core 12 uses the ultrasonic wave to atomize the liquid substrate to form the aerosol. Certainly, the atomization core 12 may further include another element capable of atomizing the liquid substrate to form the aerosol.

[0063] In some embodiments, the first chamber 111 can store the liquid substrate, and an amount of the liquid substrate stored in the first chamber 111 may be less than or equal to 2 ml, but is not limited thereto; and the liquid substrate in the second chamber 211 can enter the first chamber 111 to supply the liquid substrate to the first chamber 111. In another embodiment, the first chamber Illis mainly configured to guide the liquid substrate in the second chamber 211 to the atomization core 12 for the atomization core 12 to atomize.

[0064] To prevent leakage from the first module 1, the first module 1 further includes a fiber element 13. The fiber element 13 is arranged in the first chamber 111, capable of adsorbing the liquid substrate and retaining at least part of the adsorbed liquid substrate. The fiber element 13 includes, but is not limited to, one of the following materials: a cotton fiber, a polypropylene fiber, a polyester fiber, a nylon fiber, a porous ceramic material, a polymer fiber, or various combinations of the foregoing materials.

[0065] Referring to FIG. 5, FIG. 6, and FIG. 10 to FIG. 12, the first module 1 further includes a cup body 11, the cup body 11 defines at least part of a boundary of the first chamber 111, and the fiber element 13 is accommodated in the cup body 11. An outer surface of the fiber element 13 or an inner wall of the cup body 11 may be constructed in such a way that an air guide channel 15 is formed between the fiber element 13 and the cup body 11. The air guide channel 15 may communicate two longitudinal opposite ends of the fiber element 13. In this way, the air guide channel 15 can ensue uniform distribution of air pressure in the first chamber 111, enabling the liquid substrate in the fiber element 13 to be smoothly transferred toward the atomization core 12 through the fiber element 13. In addition, when the fiber element 13, gas in the first chamber 111, and the liquid substrate expand due to heating, or the fiber element 13, gas in the first chamber 111, and the liquid substrate expand due to a difference between internal air pressure and outside air pressure of the first chamber 111, a space can be provided for the expanded fiber element 13, the expanded liquid substrate, and the expanded gas, to prevent leakage of the liquid substrate from the first chamber 111.

[0066] In the embodiment shown in FIG. 12, a side wall of the fiber element 13 has a strip-shaped rib 131, and the strip-shaped rib 131 is configured to abut against the inner wall of the cup body 11, forming the air guide channel 15 between another part of the side wall of the fiber element 13 and the inner wall of the cup body 11, or forming the air guide channel 15 between two adjacent strip-shaped ribs 131. The strip-shaped rib 131 may extend longitudinally to two opposite end surfaces connected to the fiber element 13.

[0067] The first module 1 may further include an air guide tube, and the air guide tube is in air communication with the atomization core 12 and is configured to guide the aerosol generated by the atomization core 12 to the outside of the first module 1. The air guide tube may pass through the first chamber 111, and the fiber element 13 may surround the air guide tube. In an example, the atomization core 12 may be arranged in the air guide tube.

[0068] In some embodiments, a capacity of the second chamber 211 is greater than a capacity of the first chamber 111, and the second chamber 211 may store less than or equal to 10 ml of the liquid substrate, but is not limited thereto. The liquid substrate stored in the second chamber 211 may have a flavor the same as the liquid substrate stored in the first chamber 111, or may have a flavor different from the flavor of the liquid substrate stored in the first chamber 111. Referring to FIG. 5 and FIG. 6, the second module 2 includes a housing 21, and the housing 21 defines at least part of a boundary of the second chamber 211.

[0069] When the second module 2 and the first module 1 are in a connected state, the fluid channel for supplementing the liquid substrate from the second chamber 211 to the first chamber 111 can be established between the second module 2 and the first module 1. When the first module 1 and the third module 3 are in the connected state, a power supplying path is established between the power supply 31 and the atomization core 12.

[0070] It should be noted that the first module 1 and the second module 2 are independent of each other, requiring the first module 1 and the second module 2 to be assembled through a user operation. Therefore, the user can select the second module 2 connected to the first module 1. Different second modules 2 may vary. For example, the second chamber 211 in different second modules 2 may have different capacities, or the second chamber 211 in different second modules 2 may store liquid substrates of different flavors. Certainly, different second modules 2 may alternatively be identical.

[0071] Similarly, the third module 3 and the first module 1 are independent of each other, enabling the first module 1 and the third module 3 to be assembled through a user operation.

[0072] The second module 2 is configured to be operable, to connect the second module 2 to the first module 1 by operating the second module 2. The user may further operate the second module 2, to drive the first module 1 to be separated from the third module 3. Therefore, the second module 2 and the first module 1 can be removed and replaced together.

[0073] In some embodiments, the aerosol generation device further includes a fourth module, the 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, to be connected to the second module 2.

[0074] In other words, in the aerosol generation device in an initial state, the fourth module is detachably connected to the first end of the first module 1. When the aerosol generation device needs to be used, or when the liquid substrate 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.

[0075] When the fourth module is connected to the first module 1, the first chamber 111 can be sealed, to prevent the liquid substrate in the first chamber 111 from leaking through the first end.

[0076] In some embodiments, referring to FIG. 5 and FIG. 6, the second module 2 further includes a suction nozzle 22. The suction nozzle 22 may be integrally formed with the housing 21, or the suction nozzle 22 may be fixed to the housing 21. The suction nozzle 22 is configured for the user to hold in the mouth. The suction nozzle 22 is provided with an inhalation port 221. The user inhales, through the inhalation port 221, the aerosol generated by the first module 1. Therefore, the inhalation port 221 is in fluid communication with the air guide tube in the first module 1.

[0077] Based on this, when the fourth module is connected to the first module 1, it can not only keep the air guide tube clean, but also reduce the air convection between the first module 1 and the outside, which is beneficial to preventing leakage and deterioration of the liquid substrate in the first chamber 111. In some embodiments, the fourth module can also seal the air guide tube, to prevent the internal pressure of the first module 1 from being affected by the external pressure, helping prevent the fiber element 13 in the first chamber 111 from expanding and prevent leakage of the liquid substrate in the first chamber 111. For example, when air pressure surrounding the aerosol generation device in the initial state is reduced, the liquid substrate in the first chamber 111 can be prevented from automatically flowing out.

[0078] In some embodiments, the second module 2 and the first module 1 are not detachable from each other after the connection is established, meaning that after the second module 2 is connected to the first module 1, the two modules cannot be separated or are difficult to separate. Certainly, the connection between the second module 2 and the first module 1 may alternatively be a detachable connection, meaning that after the second module 2 is connected to the first module 1, the two modules can be separated by using a suitable operation or tool.

[0079] In some embodiments, the connection between the second module 2 and the first module 1 is a detachable connection. However, a disassembly manner after the second module 2 is connected to the first module 1 is different from a disassembly manner after the third module 3 is connected to the first module 1, or a disassembly force after the second module 2 is connected to the first module 1 is greater than a disassembly force after the third module 3 is connected to the first module 1. Therefore, when the second module 2 drives the first module 1 to be separated from the third module 3, the second module 2 can remain connected to the first module 1. In this embodiment, the fourth module is optional rather than mandatory.

[0080] Specifically, in an embodiment, that a disassembly manner after the second module 2 is connected to the first module 1 is different from a disassembly manner after the third module 3 is connected to the first module 1 includes that a connection manner of the second module 2 to the first module 1 is different from a connection manner of the third module 3 to the first module 1. For example, the second module 2 is connected to the first module 1 in a buckling connection manner, and the third module 3 is connected to the first module 1 in a magnetic connection manner. Referring to FIG. 2 to FIG. 5, the first module 1 further includes a first magnetic member 16, the third module 3 further includes a second magnetic member 33, and when the first magnetic member 16 and the second magnetic member 33 are close to each other, a magnetic force is generated between the first magnetic member 16 and the second magnetic member 33, enabling the first module 1 to remain stably connected with the third module 3. Referring to FIG. 2 and FIG. 3, one of the first module 1 and the second module 2 is provided with a first stopping edge 231 and a second stopping edge 232, and the other is provided with a buckling member 112. After the second module 2 is connected to the first end of the first module 1, the buckling member 112 is located between the first stopping edge 231 and the second stopping edge 232, and the second module 2 is configured to act on the buckling member 112 through the first stopping edge 231, to drive the first module 1 to be separated from the third module 3. In the embodiments shown in FIG. 2 and FIG. 3, the housing 21 is provided with a buckling slot 23, the first stopping edge 231 and the second stopping edge 232 are opposite to each other and define a part of boundary of the buckling slot 23, and the cup body 11 is provided with an elastic arm 113 and the buckling member 112 arranged on the elastic arm 113. When the elastic arm 113 is pressed laterally to deform the elastic arm 113, the buckling member 112 may exit the buckling slot 23, and then by applying a longitudinal force, the second module 2 may be separated from the first module 1. Certainly, the first stopping edge 231 and the second stopping edge 232 may alternatively be components of the cup body 11. Therefore, the buckling member 112 and the elastic arm 113 may be components of the housing 21.

[0081] In an embodiment, that a disassembly manner after the second module 2 is connected to the first module 1 is different from a disassembly manner after the third module 3 is connected to the first module 1 includes that a disassembly direction after the second module 2 is connected to the first module 1 is different from a disassembly direction after the third module 3 is connected to the first module 1. For example, when the first module 1 moves longitudinally in the direction away from the third module 3, the first module 1 may be separated from the third module 3, and when the second module 2 needs to rotate relative to the first module 1 in a preset direction, the second module 2 can be separated from the first module 1.

[0082] 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, and the second module 2 and the first module 1 interfere with each other when the second module 2 and the first module 1 are connected to each other, so that the second module 2 can remain stably connected to the first module 1. When the second module 2 needs to be removed from the first module 1, the disassembly force needs to overcome an 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 needs to overcome an interference force between the third module 3 and the first module 1. Therefore, when a force is applied in the direction that separates the first module 1 from the third module 3, the first module 1 is separated from the third module 3 before the second module 2 is separated from the first module 1, and when the first module 1 is separated from the third module 3, the first module 1 can remain connected to the second module 2. In this embodiment, the connection manner of the second module 2 to the first module 1 may be the same as the connection manner of the third module 3 to the first module 1, and / or the disassembly direction after the second module 2 is connected to the first module 1 may be the same as the disassembly direction after the third module 3 is connected to the first module 1.

[0083] The fluid channel between the second chamber 211 of the second module 2 and the first chamber 111 of the first module 1 may be primarily connected when the user uses the aerosol generation device, and may be disconnected when the user sets the aerosol generation device aside.

[0084] Based on this, in some embodiments, referring to FIG. 5 and FIG. 6, the second module 2 is configured to move relative to the first module 1 between a first position and a second position, where the fluid channel between the second chamber 211 and the first chamber Illis disconnected when the second module 2 is located at the first position, and is connected when the second module 2 is located at the second position. Preferably, the second module 2 moves longitudinally between the first position and the second position, but is not limited thereto.

[0085] Further, referring to FIG. 5 and FIG. 6, the first end of the first module 1 has a first docking assembly 14, the second module has a second docking assembly 24, and when the second module 2 moves between the first position and the second position, the first docking assembly 14 remains connected to the second docking assembly 24, thereby maintaining mutual interference. An interference force between the first docking assembly 14 and the second docking assembly 24 is less than the interference force between the first module 1 and the third module 3, enabling the first module 1 to remain relatively stationary with the third module 3 when the second module 2 moves between the first position and the second position. Therefore, when the fluid channel between the second chamber 211 and the first chamber 111 is switched from being disconnected to being connected or from being connected to being disconnected, the first module 1 remains relatively stationary with the third module 3.

[0086] Further, 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 in the longitudinal direction, when the first module 1 is connected to the second module 2, the first module 1 needs to provide an upward force to overcome a gravitational force of the second module 2 to support the second module 2.

[0087] The first position is located above the second position in the longitudinal direction. When the second module 2 is located at the first position, the interference force between the first docking assembly 14 and the second docking assembly 24 is greater than the gravitational force of the second module 2, enabling the second module 2 to remain at the first position, so that the fluid channel between the second chamber 211 and the first chamber 111 remains disconnected, and the fluid channel between the second chamber 211 and the first chamber 111 is prevented from being automatically connected.

[0088] 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 FIG. 5 and FIG. 6, there are two fluid channels between the second chamber 211 and the first chamber 111.

[0089] In some embodiments, the at least one fluid channel is configured to provide a liquid path, to enable the liquid substrate in the second chamber 211 to flow into the first chamber 111, where the liquid path is configured to be disconnected when air pressure in the second chamber 211 is lower than air pressure in the first chamber 111; and the at least one fluid channel is configured to provide an air path to enable air communication between the second chamber 211 and the first chamber 111, to balance air pressure in the second chamber 211 and the first chamber 111. The air path is disconnected when the second module 2 is located at the first position, and is connected when the second module 2 is located at the second position.

[0090] To simplify the structure, the liquid path and the air path may at least partially overlap, where the liquid path at least partially allows an air flow to pass through, or the air path at least partially allows the liquid substrate to pass through. Certainly, the liquid path and the air path may alternatively be independent of each other.

[0091] In some embodiments, referring to FIG. 5 and FIG. 6, the first docking assembly 14 includes a flexible plug 141. The flexible plug 141 is made of a flexible material, for example, silicone. The flexible plug 141 is provided with a first docking hole 1411, and a hole wall of the first docking hole 1411 is provided with a first convex ring 1412. The second docking assembly 24 includes a flow guide column 241, and the at least one fluid channel includes a first flow guide hole 2411 provided on a side wall of the flow guide column 241 and a second flow guide hole 2412 provided inside the flow guide column 241 and in fluid communication with the second chamber 211. Referring to FIG. 5, when the second module 2 is located at the first position, the first flow guide hole 2411 and the first chamber 111 are located at two opposite sides of the first convex ring 1412, and the first convex ring 1412 provides a sealing connection between the flexible plug 141 and the flow guide column 241, to isolate the first chamber 111 from the first flow guide hole 2411. In this way, the air path is disconnected, and the liquid path may also be disconnected. Referring to FIG. 6, when the second module 2 is located at the second position, the first flow guide hole 2411 passes through the first docking hole 1411 and is located outside of the first docking hole 1411. In this way, the air path is connected, and the liquid path may also be connected.

[0092] In the embodiments shown in FIG. 5, FIG. 6, and FIG. 8, the hole wall of the first docking hole 1411 may further be provided with a second convex ring 1413. When the second module 2 is located at the first position, the first flow guide hole 2411 is located between the first convex ring 1412 and the second convex ring 1413, the second convex ring 1413 is located between the second chamber 211 and the first flow guide hole 2411, and the second convex ring 1413 provides a sealing connection between the flexible plug 141 and the flow guide column 241, to prevent the liquid substrate in the second chamber 211 from leaking through the first flow guide hole 2411. When the second module 2 is located at the second position, the first convex ring 1412 and the second convex ring 1413 are located on a same side of the first flow guide hole 2411, and the second convex ring 1413 still provides the sealing connection between the flexible plug 141 and the flow guide column 241, to prevent the liquid substrate in the second chamber 211 from leaking through the first flow guide hole 2411.

[0093] It should be noted that, in another embodiment, the first convex ring 1412 and / or the second convex ring 1413 may be provided on an outer wall of the flow guide column 241.

[0094] In the embodiments shown in FIG. 5 and FIG. 6, the first docking assembly 14 further includes a first retaining member 142. The first retaining member 142 is connected to the flexible plug 141 and the cup body 11, and the flexible plug 141 is at least partially located between the first retaining member 142 and the cup body 11. The first retaining member 142 is configured to enable the flexible plug 141 to remain connected to the cup body 11 and prevent a 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 retaining member 142 supports the second module 2.

[0095] The second docking assembly 24 may further include a second retaining member 242 and a sealing plug 243. The sealing plug 243 may be made of a flexible material, for example, may be made of silicone. Hardness of the second retaining member 242 is greater than hardness of the sealing plug 243. The sealing plug 243 is at least partially arranged between the housing 21 and the second retaining member 242, to provide sealing between the housing 21 and the second retaining member 242. The second retaining member 242 and the sealing plug 243 match with each other to seal one end of the second chamber 211 facing the first module 1. The flow guide column 241 may be integrally formed with the second retaining member 242, or the flow guide column 241 may be arranged on the second retaining member 242.

[0096] In some embodiments, referring to FIG. 6, when the second module 2 is located at the second position, the first flow 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 flow guide hole 2411, avoiding affecting air guide of the flow guide column 241 and the air path. Certainly, when the second module 2 is located at the second position, an end portion of the flow guide column 241 may abut against the fiber element 13.

[0097] Referring to FIG. 5, FIG. 6, and FIG. 10, a wall of the cup body 11 is provided with a second docking hole 114 in communication with the first chamber 111. When the second module 2 is located at the second position, the first flow guide hole 2411 may be located in the second docking hole 114, and the first flow guide hole 2411 is spaced apart from a hole wall of the second docking hole 114, enabling air communication between the first flow guide hole 2411 and the first chamber 111.

[0098] To prevent the flow guide column 241 from tilting relative to the second docking hole 114 when the second module 2 is located at the second position, to cause the hole wall of the second docking hole 114 to block the first flow guide hole 2411, referring to FIG. 5 and FIG. 10, the hole wall of the second docking hole 114 may be provided with a protrusion 115. When the second module 2 is located at the second position, the protrusion abuts against the flow guide column 241, forming a gap in communication with the first chamber 111 between the hole wall of the second docking hole 114 and the flow guide column 241.

[0099] The protrusion 115 may be in the shape of a strip extending longitudinally. Preferably, a length of the strip-shaped protrusion 115 may be less than a depth of the second docking hole 114, to reduce the resistance to the movement of the flow guide column 241 in the second docking hole 114. A plurality of protrusions 115 may be provided, and the plurality of protrusions 115 are uniformly distributed along the hole wall of the second docking hole 114, helping a central axis of the flow guide column 241 and a central axis of the second docking hole 114 overlap.

[0100] Referring to FIG. 5 and FIG. 6, the second docking hole 114 is provided corresponding to the first docking hole 1411, and the central axis of the second docking hole 114 overlap with a central axis of the first docking hole 1411. An aperture of the second docking hole 114 is greater than an outer diameter of the flow guide column 241. The aperture of the second docking hole 114 may be greater than an aperture of the first docking hole 1411.

[0101] In some embodiments, referring to FIG. 11, the first module 1 includes an auxiliary air channel 17, and the auxiliary air channel 17 enables air communication between the first chamber 111 and the air guide tube, to balance the air pressure in the first chamber 111 with air pressure in the air guide tube, to prevent leakage of the liquid substrate in the first chamber 111.

[0102] Referring to FIG. 8 and FIG. 10, the cup body 11 is provided with a fixing hole 116 and a through hole 117 in fluid communication with the first chamber 111. The flexible plug 141 includes a tubular portion 1415 whose side wall has a notch 1414, and the air guide tube is in communication with the tubular portion 1415. The tubular portion 1415 is at least partially embedded and retained in the fixing hole 116, and the notch 1414 on the tubular portion 1415 is a component of the auxiliary air channel 17. The tubular portion 1415 is at least partially embedded and retained in the fixing hole 116 of the cup body 11.

[0103] The flexible plug 141 is partially arranged on a surface of the cup body 11 facing the second module 2, and the surface of the cup body 11 facing the second module 2 is provided with a flow guide groove 118. One end of the flow guide groove 118 is in communication with the through hole 117, and the other end of the flow guide groove 118 extends to communicate with the fixing hole 116, to further communicate with the notch 1414 on the tubular portion 1415. The flow guide groove 118 and the through hole 117 are also components of the auxiliary air channel 17.

[0104] Therefore, when the air pressure in the first chamber Illis greater than the air pressure in the air guide tube, gas in the first chamber 111 enters the tubular portion 116 through the through hole 117, the flow guide groove 118, and the notch 1414 in sequence, and then enters the air guide tube or the second module 2 / the fourth module. When the air pressure in the first chamber Illis less than the air pressure in the air guide tube, gas in the second module 2 / the fourth module or in the air guide tube may first enter the tubular portion 116, and then flow into the first chamber 111 through the notch 1414, the flow guide groove 118, and the through hole 117 in sequence. Therefore, the air pressure in the first chamber 111 and the air guide tube can be balanced. Since the second chamber 211 may be in air communication with the first chamber 111 through an air flow, when the air path is connected, the air pressure in the second chamber 211 may also be substantially balanced with the air pressure in the air guide tube.

[0105] In some embodiments, referring to FIG. 4 to FIG. 6, the third module 3 further includes a shell 32 having an open proximal end, an interior of the shell 32 includes an accommodating cavity 321, and the accommodating cavity 321 is adjacent to the proximal end of the shell 32. The first module 1 is removably retained in the accommodating cavity 321, the second module 2 is partially removably retained in the accommodating cavity 321, and the second module 2 is partially exposed outside the shell 32 for the user to operate. The user may operate the part of the second module 2 that is exposed outside the shell 32 to separate the first module 1 completely covered by the shell 32 from the third module 3 and separate the first module 1 from the accommodating cavity 321.

[0106] Referring to FIG. 2 and FIG. 4, the first module 1 further includes a first electrode 18 electrically connected to the atomization core 12, the first electrode 18 is fixed on the bottom of the first module 1, and the third module 3 further includes a second electrode 34 electrically connected to the power supply 31. When the first module 1 is connected to the third module 3, the first electrode 18 abuts against the second electrode 34 and the first electrode 18 remains electrically connected to the second electrode 34.

[0107] In some embodiments, the bottom of the first module 1 is provided with an air hole 19 in fluid communication with the atomization core 12, an air inlet hole 212 of the aerosol generation device is provided on the housing 21, and the air inlet hole 212 is in fluid communication with the air hole 19 of the first module 1. External air enters the interior of the housing 21 through the air inlet hole 212, then enters the first module 1 through the air hole 19, and then combines with vapor that is formed by the liquid substrate under the action of the atomization core 12 to form the aerosol. The housing 21 may be provided with an adjustment valve 213, and the adjustment valve 213 adjusts an amount of air entering the housing 21 through the air inlet hole 212, to adjust an inhalation resistance of the aerosol generation device.

[0108] In some embodiments, referring to FIG. 5 and FIG. 6, the second module 2 further includes a connecting tube 25 internally having an air channel. The connecting tube is arranged inside the housing 21, one end of the connecting tube 25 is in communication with the inhalation port 221, and the other end of the connecting tube 25 passes through the second docking assembly 24 and is exposed to the outside, to dock with the first docking assembly 14.

[0109] The connecting tube 25 is interference-fitted with the sealing plug 243 when passing through the second docking assembly 24, enabling a sealing connection between the connecting tube 25 and the sealing plug 243, to prevent leakage of the liquid substrate in the second chamber 211.

[0110] The flexible plug 141 is provided with a docking hole 1416 provided corresponding to and in communication with the tubular portion 1415. When the second module 2 is connected to the first module 1, an end portion of the connecting tube 25 is embedded in the docking hole 1416 of the flexible plug 141, and is interference-fitted with the docking hole 1416, enabling a sealing connection between the first module 1 and the second module 2, to prevent leakage of the aerosol.

[0111] To prevent a large amount of condensate formed by the aerosol from accumulating on an inner wall of the connecting tube 25, to cause the user to inhale the condensate into the mouth through the inhalation port 221, referring to FIG. 5 and FIG. 6, a strip-shaped groove 251 is provided on the inner wall of the connecting tube 25. The strip-shaped groove 251 extends to a distal end of the connecting tube 25, and is configured to guide the condensate in the connecting tube 25 into the tubular portion 1415. In this way, the condensate may flow into the atomization core 12, and flow into the first chamber 111 along the auxiliary air channel 17. An extended length of the strip-shaped groove 251 may be greater than or equal to 1 / 2 of a length of the connecting tube 25, and may be less than or equal to 4 / 5 of the length of the connecting tube 25. This is not specifically limited herein.
