Description

Technical Field

[0001] The present application relates to the technical field of aerosol generation, and in particular to an aerosol generating device. Background Art

[0002] An aerosol generating device is a device that can atomize a liquid preparation to form an aerosol. However, in some exemplary prior art, there is an aerosol generating device, including a nebulizer, a spare oil storage tank and a power supply assembly, the spare oil storage tank is connected to the nebulizer through a liquid path to replenish the liquid matrix in the oil tank in the nebulizer, and the power supply assembly is connected to the nebulizer with a circuit to provide the nebulizer with electricity for atomizing the liquid matrix through the circuit. The spare oil storage tank is detachably connected to the nebulizer so that the spare oil storage tank can be replaced after the liquid matrix in the spare oil storage tank is exhausted.

[0003] However, the atomization amount of the atomization core used for atomizing the liquid matrix in the existing atomizer is limited. The sum of the liquid matrix reserve amount in the spare oil storage tank and the liquid matrix reserve amount in the atomizer has basically reached the upper limit of the atomization of the atomization core. When the liquid matrix in the spare oil tank is exhausted, the service life of the atomization core is not long enough to support it to continue to atomize the liquid matrix in the new spare oil tank according to the expected effect, which not only causes waste after replacing the new spare oil tank, but also leads to a decrease in user experience. Utility Model Content

[0004] The purpose of the present application is to provide an aerosol generating device, which can make the first module and the second module independent of each other, and when the second module is replaced, the first module with the atomization core can be separated from the third module, so that the second module can be replaced at the same time, so that the aerosol generating device can provide an experience that meets the user's expectations during repeated use.

[0005] At least one embodiment of the present application provides an aerosol generating device, the aerosol generating device comprising:

[0006] A first module, comprising a first chamber for storing a liquid matrix and an atomizing core for atomizing the liquid matrix to generate an aerosol, wherein the first chamber is in fluid communication with the atomizing core, and the first module has a first end and a second end disposed opposite to each other;

[0007] a second module having a second chamber for storing a liquid matrix therein, the second module being independent of the first module and being connectable to a first end of the first module, and establishing a fluid passage for replenishing the liquid matrix from the second chamber to the first chamber when the second module is in a connected state with the first module; and

[0008] A third module is detachably connected to the second end of the first module, and the third module includes a power supply, and the power supply is used to establish a power supply path between the atomizer core when the third module is in a connected state with the first module;

[0009] The second module is configured to provide a user operation to establish a connection with the first module, and can drive the first module to separate from the third module.

[0010] As an example, after the second module and the first module are connected, they cannot be disassembled from each other.

[0012] The disassembly method of the second module after being connected to the first module is different from the disassembly method of the third module after being connected to the first module; or

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

[0014] As an example, the third module further comprises a shell with an open proximal end, and the interior of the shell comprises a receiving cavity disposed adjacent to the proximal end of the shell;

[0015] The first module is removably retained in the receiving cavity, and a portion of the second module is removably retained in the receiving cavity, and is partially exposed outside the housing for user operation.

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

[0017] As an example, the second module is configured to be movable between a first position and a second position relative to the first module;

[0020] The interference force between the first docking assembly and the second docking assembly is smaller than the interference force between the first module and the third module, so that when the second module moves between the first position and the second position, the first module and the third module remain relatively stationary.

[0021] As an example, the interference force between the first docking assembly and the second docking assembly is greater than the gravity of the second module, so that the second module can be maintained in the first position.

[0028] The second module comprises a guide column, and at least one of the fluid channels comprises a first guide hole opened on the wall of the guide column and a second guide hole arranged inside the guide column and in fluid communication with the second chamber;

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

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

[0031] When the second module is located at the second position, the protrusion abuts against the guide column, so that there is a gap between the hole wall of the second docking hole and the guide column to connect to the first chamber, and the first guide hole is located in the second docking hole and is set corresponding to the gap.

[0061] Please refer to Figure 1-Figure 9Some embodiments of the present application provide an aerosol generating device, which includes a first module 1, a second module 2, and a third module 3 that are independent of each other, wherein the second module 2 is connected to the first end of the first module 1 by assembly, and the third module 3 is connected to the second end of the first module 1 by assembly, and the first end and the second end can be arranged relative to each other, so that the first module 1, the second module 2, and the third module 3 can be arranged in the longitudinal direction. Of course, the first end and the second end can also be located on two adjacent side surfaces of the first module 2.

[0062] The first module 1 includes a first chamber 111 and an atomizer core 12 capable of atomizing a liquid matrix to form an aerosol, and the first chamber 111 is fluidically connected to the atomizer core 12; the second module 2 includes a second chamber 211 for storing a liquid matrix therein, and after the first module 1 is connected to the second module 2, a fluid channel for fluidly connecting the first chamber 111 and the second chamber 211 is formed between the second module 2 and the first module 1; the third module 3 includes a power supply 31, and the power supply 31 is used to provide power for the atomizer core 12 to atomize the liquid matrix.

[0063] Wherein, liquid matrix can comprise the liquid containing tobacco material that contains volatile tobacco flavor component, can also be the liquid that comprises non-tobacco material.Liquid matrix can comprise water, medicinal liquid, solvent, ethanol, plant extract, spices, flavoring agent or vitamin mixture etc., and spices can comprise betel nut extract, menthol, European mint, green mint oil, various fruity fragrance components etc., but is not limited to this.Flavoring agent can comprise the composition that can provide various fragrance or local flavor to the user.Vitamin mixture can be the mixture that is mixed with at least one in vitamin A, vitamin B, vitamin C and vitamin E, but is not limited to this.Based on the different attributes of liquid matrix, aerosol generating device can be used for different fields, such as, medical treatment, electronic aerosol atomization etc.

[0064] In some embodiments, the atomizing core 12 includes an imbibition element and a heating element, and the heating element is disposed on the imbibition element. The imbibition element may 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 to generate an aerosol. The porous body may be a fiber, such as cotton fiber, polypropylene fiber, polyester fiber or nylon fiber. The porous body may be a porous ceramic or a porous metal, and the present application does not limit the structure and composition of the porous body.

[0065] In some embodiments, the atomizer core 12 may include an ultrasonic element capable of generating ultrasonic waves, and the atomizer core 12 utilizes the ultrasonic waves to atomize the liquid matrix to form an aerosol. Of course, the atomizer 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 liquid matrix, and the amount of liquid matrix stored can be less than or equal to 2 ml, but not limited thereto; the liquid matrix in the second chamber 211 can enter the first chamber 111 to supply the 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 atomizer core 12 for atomization by the atomizer core 12.

[0067] In order to prevent the first module 1 from leaking, the first module 1 further includes a fiber element 13, which is disposed in the first chamber 111 and can absorb the liquid matrix and retain at least a portion of the liquid matrix absorbed by it. 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] Please refer to Figure 5 , Figure 6 , Figure 10-12 The first module 1 further includes a cup body 11, which defines at least part of the boundary of the first chamber 111, and the fiber element 13 is contained in the cup body 11. By constructing the outer surface of the fiber element 13 or the inner wall of the cup body 11, an air guide channel 15 can be provided between the fiber element 13 and the cup body 11, and the air guide channel 15 can connect the two opposite ends of the fiber element 13 in the longitudinal direction: on the one hand, the air guide channel 15 can make the air pressure in the first chamber 111 uniform, so that the liquid matrix in the fiber element 13 can be smoothly transferred by the fiber element 13 toward the atomization core 12; on the other hand, when the fiber element 13, the gas and the liquid matrix in the first chamber 111 are heated and expanded, or when the fiber element 13, the gas and the liquid matrix in the first chamber 111 are expanded under the pressure difference between the inside and outside of the first chamber 111, a clearance space can be provided for the expanded fiber element 13, the liquid matrix and the gas, so as to prevent the liquid matrix from leaking out of the first chamber 111.

[0069] In such Fig.12 In the illustrated embodiment, the side wall of the fiber element 13 has a strip convex rib 131, and the strip convex rib 131 is used to abut against the inner wall of the cup body 11, so that the air guide channel 15 is provided between the other part of the side wall of the fiber element 13 and the inner wall of the cup body 11, or the air guide channel 15 is provided between two adjacent convex ribs 13. The strip convex rib 131 can extend longitudinally to connect two oppositely disposed end surfaces of the fiber element 13.

[0070] The first module 1 may further include an air guide tube, which is in air-conducting communication with the atomizer core 12 and is used to guide the aerosol generated by the atomizer 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 be arranged around the air guide tube. In one example, the atomizer core 12 may be arranged 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, and the second chamber 211 can store less than or equal to 10 ml of liquid matrix, but is not limited thereto. The liquid matrix stored in the second chamber 211 can have the same flavor as the liquid matrix stored in the first chamber 111, or can have a different flavor. Figure 5 and Figure 6 The second module 2 includes a shell 21 , which 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 for replenishing the liquid matrix 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 connected, a power supply path is established between the power source 31 and the atomizer core 12.

[0073] It should be noted that the first module 1 and the second module 2 are independent of each other, so that the first module 1 and the second module 2 need to be assembled together under the operation of the user, so the user can select the second module 2 connected to the first module 1. Different second modules 2 can be different, for example, the second chambers 211 in different second modules 2 can have different capacities, or the second chambers 211 in different second modules 2 can store liquid matrices of different flavors; of course, different second modules 2 can also be completely the same.

[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 operation of the user.

[0075] Among them, the second module 2 is configured to be operable so that the second module 2 can be connected to the first module 1 by operating the second module 2. The user can also operate the second module 2 to drive the first module 1 and separate the first module 1 from the third module 3. Therefore, the second module 2 and the first module 1 can be removed and replaced together.

[0076] In some embodiments, the aerosol generating device further comprises 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 .

[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 instead of the fourth module.

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

[0079] In some embodiments, reference may be made to Figure 5 and Figure 6 The second module 2 further includes a nozzle 22, which can be integrally formed with the shell 1, or fixed to the shell 21. The nozzle 22 is used for the user to hold in the mouth, and has an air inlet 221. The user inhales the aerosol generated by the first module 1 by sucking the air inlet 221, so the air inlet 221 is connected to the air guide fluid in the first module 1.

[0080] Based on this, when the fourth module is connected to the first module 1, it can not only keep the air duct clean, but also reduce the air convection between the first module 1 and the outside, which is beneficial to preventing the 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 air pressure outside, which helps to prevent the fiber element 13 in the first chamber 111 from expanding and preventing the liquid matrix in the first chamber 111 from leaking; for example, when the ambient air pressure of the aerosol generating device in the initial state decreases, 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 cannot be disassembled from each other after the connection is established, so that after the second module 2 is connected to the first module 1, the two cannot be separated or are difficult to separate. Of course, the connection between the second module 2 and the first module 1 can also be a detachable connection, so that after the second module 2 is connected to the first module 1, the two can be separated from each other through appropriate operations or tools.

[0082] In some embodiments, the connection between the second module 2 and the first module 1 is detachable, but the disassembly method after the second module 2 and the first module 1 are connected is different from the disassembly method after the third module 3 and the first module 1 are connected, or the disassembly force after the second module 2 and the first module 1 are connected is greater than the disassembly force after the third module 3 and the first module 1 are connected, so that the second module 2 and the first module 1 can remain connected during the process of the second module 2 driving the first module 1 to separate from the third module 3. In this embodiment, the fourth module is optional but not mandatory.

[0083] Specifically, in one embodiment, the disassembly method after the second module 2 is connected to the first module 1 is different from the disassembly method after the third module 3 is connected to the first module 1, including the connection method between the second module 2 and the first module 1 is different from 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 connection, and the third module 3 and the first module 1 are connected by a magnetic connection. Please refer to Figure 2-Figure 5 The first module 1 further includes a first magnetic member 16, and the third module 3 further includes a second magnetic member 33. When the first magnetic member 16 and the second magnetic member 33 are close to each other, there is a magnetic attraction between the two, so that the first module 1 and the third module 3 are stably connected. Please refer to Figure 2 and Figure 3 , one of the first module 1 and the second module 2 has a first stop edge 231 and a second stop edge 232, and the other is provided with a buckle 112. After the second module 2 is connected to the first end of the first module 1, the buckle 112 is located between the first stop edge 231 and the second stop edge 232, and the second module 2 is configured to drive the first module 1 to separate from the third module 3 by the first stop edge 231 acting on the buckle 112. Figure 2 and Figure 3 In the illustrated embodiment, a snap groove 23 is provided on the housing 21, a first stop edge 231 and a second stop edge 232 are arranged opposite to each other and define a part of the boundary of the snap groove 23, and an elastic arm 113 and a snap member 112 arranged on the elastic arm 113 are provided on the cup body 11, when the elastic arm 113 is squeezed in the transverse direction to deform the elastic arm 113, the snap member 112 can withdraw from the snap groove 23, and then a force is applied in the longitudinal direction, so that the second module 2 can be separated 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 snap member 112 and the elastic arm 113 can therefore be components of the housing 21.

[0084] In one embodiment, the disassembly method after the second module 2 is connected to the first module 1 is different from the disassembly method after the third module 3 is connected to the first module 1, including that the disassembly direction after the second module 2 is connected to the first module 1 is different from the disassembly direction after the third module 3 is connected to the first module 1. For example, when the first module 1 is moved in the longitudinal direction away from the third module 3, the first module 1 can be separated from the third module 3, and the second module 2 can be separated from the first module 1 only when the second module 2 is rotated relative to the first module 1 in a preset direction.

[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. The second module 2 and the first module 1 interfere with each other when they are connected to each other, so that the two can maintain a stable connection. When the second module 2 needs to be removed from the first module 1, the disassembly force needs to 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 needs to overcome the interference force between the third module 3 and the first module 1. Therefore, when a force is applied in a direction to separate the first module 1 from 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, and when the first module 1 and the third module 3 are separated, 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 and the first module 1 are connected can be the same as the disassembly direction after the third module 3 and the first module 1 are connected.

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

[0087] Based on this, in some embodiments, reference may be made to Figure 5 and Figure 6 The second module 2 is configured to be movable between a first position and a second position relative to the first module 1; 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 is 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 the present invention is not limited thereto.

[0088] For further information, please refer to Figure 5 and Figure 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. When the second module 2 moves 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. Among them, the interference force between the first docking component 14 and the second docking component 24 is smaller 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 still, so that when the fluid channel between the second chamber 211 and the first chamber 111 switches from disconnection to conduction, or switches from conduction to disconnection, the first module 1 and the third module 3 remain relatively still.

[0089] Furthermore, since the first module 1 and the second module 2 are arranged longitudinally and the second module 2 is located longitudinally above the first module 1, 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 to support the second module 2.

[0090] The first position is located longitudinally above the second position. When the second module 2 is located at 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 the fluid channel between the second chamber 211 and the first chamber 111 is prevented from automatically connecting.

[0091] In the present application, the fluid passage between the second chamber 211 and the first chamber 111 may be at least partially one. Figure 5 and Figure 6 In the illustrated embodiment, 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 to allow the liquid matrix in the second chamber 211 to flow into the first chamber 111, wherein the liquid path is configured to be disconnected 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 to conduct air to connect the second chamber 211 and the first chamber 111, so 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 located in the first position 1, and is connected when the second module 2 is located in the second position.

[0093] To simplify the structure, at least part of the liquid path and the gas path may overlap, at least part of the liquid path allows airflow to pass through, or at least part of the gas path allows liquid matrix to pass through. Of course, the liquid path and the gas path may also be independent of each other.

[0094] In some embodiments, reference may be made to Figure 5 and Figure 6 The first docking assembly 14 includes a flexible plug 141, which is made of a flexible material, such as silicone, and has a first docking hole 1411, and a first convex ring 1412 on the hole wall of the first docking hole 1411; the second docking assembly 24 includes a guide column 241, and at least one fluid channel includes a first guide hole 2411 opened on the side wall of the guide column 241 and a second guide hole 2412 arranged inside the guide column 241 and in fluid communication with the second chamber 211. Please refer to Figure 5When the second module 2 is in the first position, the first guide hole 2411 and the first chamber 111 are located on 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 guide column 241, so that the first chamber 111 is isolated from the first guide hole 2411, thereby disconnecting the gas path and the liquid path. Please refer to Figure 6 When the second module 2 is located at the second position, the first guide hole 2411 passes through the first docking hole 1411 and is located outside the first docking hole 1411, so that the gas path is connected and the liquid path can also be connected.

[0095] In such Figure 5 , Figure 6 and Figure 8 In the illustrated embodiment, a second convex ring 1413 may also be provided on the hole wall of the first docking hole 1411. 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 matrix 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 the same side of the first flow guide hole 2411, and the second convex ring 1413 still provides a sealing connection between the flexible plug 141 and the flow guide column 241 to prevent the liquid matrix in the second chamber 211 from leaking through the first flow 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 such Figure 5 and Figure 6 In the illustrated embodiment, the first docking assembly 14 further includes a first retaining member 142, the first retaining member 142 connects the flexible plug 141 and the cup body 11, and at least a portion of the flexible plug 141 is located between the first retaining member 142 and the cup body 11, and the first retaining member 142 is used to keep the flexible plug 141 connected to the cup body 11 and to prevent the flexible plug 141 from longitudinally displacing 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.

[0098] The second docking assembly 24 may further include a second retaining member 242 and a sealing plug 243, wherein the sealing plug 243 may be made of a flexible material, such as silicone. The hardness of the second retaining member 242 is greater than the hardness of the sealing plug 243. The sealing plug 243 is at least partially disposed between the housing 21 and the second retaining member 242 to provide a seal between the housing 21 and the second retaining member 242, and the second retaining member 242 and the sealing plug 243 cooperate with each other to seal the end of the second chamber 211 facing the first module 1. The guide column 241 and the second retaining member 242 may be integrally formed, or the guide column 241 may be disposed on the second retaining member 242.

[0099] In some embodiments, reference may be made to Figure 6 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 and thus affecting the air conduction and air path of the guide column 241. 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 Figure 5 , Figure 6 and Fig.10 A second docking hole 114 connected to the first chamber 111 is opened on the wall of the cup body 11. When the second module 2 is located at 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] In order to prevent the guide column 241 from tilting relative to the second docking hole 114 when the second module 2 is located at the second position, causing the hole wall of the second docking hole 114 to block the first guide hole 2411, please refer to Figure 5 and Fig.10 The hole wall of the second docking hole 114 may have a protrusion 115 , and when the second module 2 is located at the second position, the protrusion abuts against the guide column 241 , so that a gap connecting the first chamber 111 is provided between the hole wall of the second docking hole 114 and the guide column 241 .

[0102] The protrusion 115 may be in the shape of a strip extending in the longitudinal direction, and preferably the length of the strip protrusion 115 may be smaller than the depth of the second docking hole 114, so as to reduce the resistance of the guide column 241 moving in the second docking hole 114. There may be a plurality of protrusions 115, and the plurality of 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] Please refer to Figure 5 and Figure 6 The second docking hole 114 is arranged corresponding to the first docking hole 1411, and the central axis of the second docking hole 114 can coincide with the central axis of the first docking hole 1411. The aperture of the second docking hole 114 is larger than the outer diameter of the guide column 241. The aperture of the second docking hole 114 can be larger than the aperture of the first docking hole 1411.

[0104] In some embodiments, reference may be made to Fig.11 The first module 1 has an auxiliary airway 17 , which communicates the first chamber 111 with the air pipe to balance the air pressure in the first chamber 111 and the air pipe, thereby preventing leakage of the liquid matrix in the first chamber 111 .

[0105] Please refer to convex 8 and Fig.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 is provided with a tubular portion 1415 with a notch 1414 on the side wall. The air guide tube is connected to the tubular portion 1415. At least a portion of the tubular portion 1415 is embedded in the fixing hole 116 and maintained. The notch 1414 on the tubular portion 1415 is a component of the auxiliary airway 17. Among them, at least a portion of the tubular portion 1415 is embedded in the fixing hole 116 of the cup body 11 and maintained.

[0106] The flexible plug 141 is partially arranged on the surface of the cup body 11 facing the second module 2, and a guide groove 118 is opened 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 portion 1415. The guide groove 118 and the through hole 117 are also components of the auxiliary airway 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 enters the tubular portion 116 through the through hole 117, the guide groove 118 and the notch 1414 in sequence, and then enters the air duct or the second module 2 / the 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 / the fourth module or the air duct can first enter the tubular portion 116, and then flow into the first chamber 111 through the notch 1414, the guide groove 118 and the through hole 117 in sequence. Therefore, the air pressure balance between the first chamber 111 and the air duct can be maintained. Since the second chamber 211 can be connected to the first chamber 111 through air flow, when the air path is connected, the second chamber 211 can also basically balance the air pressure in the air duct.

[0108] In some embodiments, reference may be made to Figure 4-Figure 6The third module 3 further comprises a housing 32 with an open proximal end, and a receiving cavity 321 is provided inside the housing 32, and the receiving cavity 321 is arranged adjacent to the proximal end of the housing 32; wherein the first module 1 is removably held in the receiving cavity 321, and a part of the second module 2 is removably held in the receiving cavity 321, and is partially exposed outside the housing 32 for user operation. The user can separate the first module 1 completely blocked by the housing 32 from the third module 3 and detach it from the receiving cavity 321 by operating the part of the second module 2 exposed outside the housing 32.

[0109] Please refer to Figure 2-Figure 4 The first module 1 also includes a first electrode 18 electrically connected to the atomizer core 12, and 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 is connected to the third module 3, 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, the bottom of the first module 1 is provided with an air hole 19 that is fluidically connected to the atomizing core 12, and the air inlet 212 of the aerosol generating device is provided on the housing 21, and the air inlet 212 is fluidically connected to the air hole 19 of the first module 1, and the outside air enters the housing 21 through the air inlet 212, and then enters the first module 1 through the air hole 19, and then combines with the aerosol formed by the liquid matrix under the action of the atomizing core 12 to form an aerosol. The housing 21 may be provided with a regulating valve 213, and the regulating valve 213 is used to adjust the amount of air entering the housing 21 through the air inlet 212, thereby adjusting the suction resistance of the aerosol generating device.

[0111] In some embodiments, please refer to Figure 5 and Figure 6 The second module 2 also includes a connecting pipe 25 with an air passage inside. The connecting pipe is arranged inside the shell 21, and one end of the connecting pipe 25 is connected to the air inlet 221, and the other end passes through the second docking component 24 and is exposed to the outside to dock with the first docking component 14.

[0112] The connecting tube 25 is interference-fitted with the sealing plug 243 when passing through the second docking assembly 24, so that the two are sealed and connected to prevent the liquid matrix in the second chamber 211 from leaking.

[0113] The flexible plug 141 has a docking hole 1416 which is arranged corresponding to and connected to 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 docking hole 1416 of the flexible plug 141 and has an interference fit with the docking hole 1416, so that the two are sealed and connected to prevent aerosol leakage.

[0114] In order to prevent the condensate formed by the aerosol from accumulating on the inner wall of the connecting tube 25, so that the user inhales the condensate into the mouth when sucking the air inlet 221. Figure 5 and Figure 6 A strip groove 251 is provided on the inner wall of the connecting tube 25, and the strip groove 251 extends to the distal end of the connecting tube 25, and is used to guide the condensate in the connecting tube 25 into the tubular portion 1415, so that the condensate can flow into the atomizer core 12, and then flow into the first chamber 111 along the auxiliary airway 17. The extension length of the strip groove 251 can be greater than or equal to 1 / 2 of the length of the connecting tube 25, and can be less than or equal to 4 / 5 of the length of the connecting tube 25, which is not specifically limited here.

Furthermore, it is possible for a person of ordinary skill in the art to make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to the present application.
