Description

Technical Field

[0001] This utility model relates to the field of aerosol generation technology, and more specifically, to an aerosol generation device. Background Technology

[0002] Aerosol generators are a new type of electronic product that uses a heating element to heat aerosol-forming substances to produce inhalable aerosols. Compared to traditional cigarettes, aerosol generators do not burn, thus avoiding the various harmful chemicals produced by tobacco combustion. They also eliminate the harm to others and environmental pollution caused by "secondhand smoke." Therefore, aerosol generators are healthier and more environmentally friendly than traditional cigarettes.

[0003] Currently, the most popular aerosol generators on the market are disposable. They consist of an outer shell and an atomizing unit fixed inside the shell. The atomizing unit includes an atomizing module for atomizing the vapor-forming substance and a power supply module for providing electrical energy. While disposable aerosol generators offer users many conveniences, their extensive use can easily lead to environmental pollution and resource waste. Therefore, the recycling of disposable aerosol generators is of great significance. However, existing disposable aerosol generators are not easy to recycle; after use, they can only be discarded as a whole, which is not environmentally friendly. Utility Model Content

At least a portion of the outer wall of the power supply module elastically abuts against the cavity wall of the receiving cavity, thereby enabling the power supply module to be detachably connected to the outer shell.

[0007] In one embodiment, the atomizing module includes a liquid storage tube, an elastic sealing top cover, an elastic sealing base, an atomizing core, and a connecting base. The elastic sealing top cover is connected to a first end of the liquid storage tube and elastically abuts against the mouthpiece. A first conductive hole is located at the elastic sealing top cover and communicates with the atomizing core. The elastic sealing base is connected to a second end of the liquid storage tube. The atomizing core is located inside the liquid storage tube and is connected to the elastic sealing base. The connecting base is connected to the elastic sealing base. The power supply module is detachably connected to the connecting base, and when the power supply module moves relative to the outer casing under external force, the atomizing module moves together with the power supply module.

[0008] In one embodiment, the atomizing module further includes a first elastic connecting ring, which is sleeved on the outer peripheral surface of the connecting base; a docking groove is provided at the first end face of the power supply module, the connecting base extends into the docking groove, and the first elastic connecting ring elastically abuts against the groove wall of the docking groove.

[0009] In one embodiment, the wall of the first conductive hole is provided with a limiting step; the opening of the vapor discharge hole facing the atomizing module extends into the first conductive hole to form an extension tube, the extension tube extending into the first conductive hole and abutting against the limiting step.

[0010] In one embodiment, the elastic sealing base is provided with a second conductive hole and an electrode slot. The second conductive hole penetrates both end faces of the elastic sealing base that are opposite to each other, and the electrode slot is located at the end face of the elastic sealing base. The atomizing core includes a vent tube, a liquid guiding component, a heating element, and an electronic wire. The vent tube is inserted into the second conductive hole, the liquid guiding component is located inside the vent tube, the heating element is in contact with the liquid guiding component, and the electronic wire is connected to the heating element and extends through the second conductive hole into the electrode slot. The power supply module extends into the electrode slot and clamps the electronic wire with the slot wall of the electrode slot, so that the power supply module is electrically connected to the atomizing module.

[0011] In one embodiment, the connecting base is provided with a positioning hole, the positioning hole corresponding to the position of the electrode slot, and the power supply module extends into the electrode slot through the positioning hole.

[0012] In one embodiment, the power supply module includes a bracket, electrode posts, a battery, a bottom cover, and a second elastic connecting ring. The bracket is at least partially located within the receiving cavity and is detachably connected to the atomizing module. The electrode posts are mounted on the bracket and electrically connected to the atomizing module. The battery is mounted on the bracket and electrically connected to the electrode posts. The bottom cover is at least partially located outside the outer casing and connected to the bracket. The second elastic connecting ring is sleeved on the bottom cover or the bracket and elastically abuts against the cavity wall of the receiving cavity, so that the power supply module is detachably connected to the outer casing.

[0013] In one embodiment, the power supply module further includes an isolation tube and an airflow sensor.

The atomizing module and the power supply module are detachably connected, with the power supply module extending outside the outer shell. The outer wall of the power supply module elastically abuts against the cavity wall, thus enabling the detachable connection between the power supply module and the outer shell. Therefore, when recycling is required, the user can hold the outer shell with one hand and clamp the bottom cover with the other, applying axial force to the outer shell to pull the atomizing body out. Then, the atomizing module and the power supply module can be separated, facilitating classified recycling, being more environmentally friendly, and avoiding resource waste.

[0017] Furthermore, during normal use, if the atomizing material is depleted and the atomizing module needs to be replaced, the atomizing body can be pulled out to replace the new atomizing module without discarding the outer casing and power supply module, thus reducing the environmental burden. Finally, since the power supply module and the outer casing are detachably connected by elastic contact, the problems of difficult disassembly caused by threaded or snap-fit ​​connections are avoided, making this invention more convenient for users.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0027] Please see Figures 1 to 7 This invention provides an aerosol generating device, comprising a housing 100 and an atomizing body 200. The housing 100 is provided with an air inlet 11, a mouthpiece 12, a receiving cavity 13, and an opening 14, with the air inlet 11 communicating with the receiving cavity 13. The mouthpiece 12 is located at the first end of the housing 100 and is provided with a vapor discharge hole 121, through which vapor is discharged into the user's mouth for inhalation. The opening 14 is located at the second end of the housing 100, with the first and second ends of the housing 100 positioned opposite each other. The receiving cavity 13 communicates with the mouthpiece 12 and the opening 14. The housing 100 can be cylindrical or cuboid, etc., and its shape is not specifically limited herein. Furthermore, the housing 100 can be formed by one or more tubular structures connected together.

[0028] The atomizing body 200 is detachably installed in the receiving cavity 13 and extends out from the opening 14, thus facilitating the removal of the atomizing body 200 from the outer shell 100. The atomizing body 200 includes an atomizing module 201 and a power supply module 301. The atomizing module 201 is movably disposed within the receiving cavity 13, meaning that the atomizing module 201 is not fixed to the outer shell 100. Under the action of external force, the atomizing module 201 can move relative to the receiving cavity 13 to remove the atomizing module 201 from the receiving cavity 13.

[0029] The first end of the atomizing module 201 is provided with a first conduction hole 202, which communicates with the vapor discharge hole 121 to transport the vapor generated by the atomizing module 201 to the vapor discharge hole 121. The opening of the vapor discharge hole 121 facing the atomizing module 201 extends into the first conduction hole 202 to form an extension tube 122. The first end of the atomizing module 201 elastically abuts against the nozzle 12 and seals the steam inlet end of the vapor discharge hole 121, thereby preventing the condensed vapor in the vapor discharge hole 121 from flowing back to the outer wall surface of the atomizing body 200.

[0030] Furthermore, since the first end of the atomizing module 201 elastically abuts against the mouthpiece 12, it can prevent the atomizing body 200 from sliding arbitrarily. The second end of the atomizing module 201 is detachably connected to the power supply module 301, so that the atomizing module 201 and the power supply module 301 can be detachably connected, and the first end and the second end of the atomizing module 201 are positioned opposite each other.

[0031] Specifically, the atomizing module 201 includes a liquid storage tube 21, an elastic sealing top cover 22, an elastic sealing base 23, an atomizing core 24, a connecting base 25, and a porous liquid suction element 26. The liquid storage tube 21 is used to hold the vapor-forming substance, which can be formed by a combination of propylene glycol, glycerol, and fragrance. It is understood that as long as vapor can be generated after heating, the material of the vapor-forming substance is not specifically limited here.

[0032] The elastic sealing top cover 22 is connected to the first end of the liquid storage tube 21 and elastically abuts against the nozzle 12. The first conduction hole 202 is located at the elastic sealing top cover 22 and communicates with the atomizing core 24. The first conduction hole 202 passes through the two opposite ends of the elastic sealing top cover 22. The wall of the first conduction hole 202 is provided with a limiting step 203. The extension tube 122 extends into the first conduction hole 202 and abuts against the limiting step 203, thereby improving the sealing performance.

[0033] The elastic sealing base 23 is connected to the second end of the liquid storage tube 21 to seal the second end of the liquid storage tube 21. The elastic sealing base 23 is provided with a second conduction hole 231 and an electrode slot 232. The second conduction hole 231 passes through the two opposite end faces of the elastic sealing base 23 and communicates with the air inlet 11. When the user inhales the aerosol, external gas flows into the receiving cavity 13 from the air inlet 11 and flows into the atomizing core 24 through the second conduction hole 231. The electrode slot 232 is located at the end face of the elastic sealing base 23. The elastic sealing top cover 22 and the elastic sealing base 23 can be made of elastic materials such as silicone.

[0034] The atomizing core 24 is located inside the liquid storage tube 21 and connected to the elastic sealing base 23. It includes a vent tube 241, a liquid guide 242, a heating element 243, and an electronic wire 244. The vent tube 241 is inserted into the second conductive hole 231. The liquid guide 242, located inside the vent tube 241, can be made of a material capable of adsorbing liquids, such as fiber or porous ceramic. The liquid guide 242 is used to adsorb the vapor-forming substance. The heating element 243 is in contact with the liquid guide 242 and can be a heating wire or heating plate, etc., to generate heat when energized, thereby atomizing the vapor-forming substance.

[0035] The electronic wire 244 is connected to the heating element 243 and extends into the electrode slot 232 via the second conductive hole 231. It is understood that as long as it can conduct electricity, the material of the electronic wire 244 is not specifically limited. The power supply module 301 extends into the electrode slot 232 and clamps the electronic wire 244 with the slot wall of the electrode slot 232, so that the power supply module 301 is electrically connected to the atomizing module 201. This mechanism eliminates the electrode components of the atomizing module 201, thus reducing costs and improving production efficiency. It is understood that as long as it can atomize the vapor-forming substance, the structure of the atomizing core 24 is not specifically limited.

[0036] The connecting base 25 is sleeved on one end of the elastic sealing base 23 and connected to the elastic sealing base 23 and the liquid storage tube 21. The power supply module 301 is detachably connected to the connecting base 25, and when the power supply module 301 moves relative to the outer casing 100 under the action of external force, the atomizing module 201 moves together with the power supply module 301. That is to say, when the power supply module 301 is pulled out from the opening 14, the atomizing module 201 is also pulled out from the opening 14 together with the power supply module 301, thus facilitating user use.

[0037] The connecting base 25 is provided with a positioning hole 251 and a positioning groove 252. The positioning hole 251 corresponds to the electrode slot 232, that is, the orthographic projection of the positioning hole 251 onto the plane where the slot of the electrode slot 232 is located is at least partially located within the slot of the electrode slot 232. The positioning groove 252 is located on the outer peripheral surface of the connecting base 25 and at the end of the atomizing module 201 facing the power supply module 301. The porous liquid suction element 26 is located inside the liquid storage tube 21 and is sleeved on the atomizing core 24 for adsorbing the vapor-forming substance. The porous liquid suction element 26 is in contact with the liquid guiding element 242 and can be made of porous materials such as porous ceramics or fibers. Preferably, the atomizing module 201 also includes a first elastic connecting ring 27, which is sleeved on the outer peripheral surface of the connecting base 25.

[0038] The first end of the power supply module 301 is inserted into the receiving cavity 13, and the second end of the power supply module 301 extends out of the outer shell 100 through the opening 14. A portion of the outer wall of the power supply module 301 elastically abuts against the cavity wall of the receiving cavity 13, allowing the power supply module 301 and the outer shell 100 to be detachably connected. That is, the power supply module 301 and the outer shell are detachably connected through elastic abutment, eliminating the need for threads or clips, thus facilitating the user's removal of the atomizing body 200. A docking groove 302 is provided at the first end face of the power supply module 301, and an air guide hole 3021 is provided on the groove wall of the docking groove 302, communicating with the air inlet 11 and the docking groove 302. The connecting base 25 extends into the docking groove 302, and the first elastic connecting ring 27 elastically abuts against the groove wall of the docking groove 302, thereby improving the reliability of the connection between the atomizing module 201 and the power supply module 301.

[0039] Specifically, the power supply module 301 includes a bracket 31, electrode posts 32, a battery 33, a bottom cover 34, and a second elastic connecting ring 35. The first end of the bracket 31 is located within the receiving cavity 13 and is detachably connected to the atomizing module 201. The second end of the bracket 31 extends from the opening 14. The bracket 31 is provided with a battery mounting groove 311, a mating groove 302, a positioning protrusion 312, and a fastening protrusion 313. The mating groove 302 and the positioning protrusion 312 are located at the first end face of the bracket 31. That is, the positioning protrusion 312 is located at the first end face of the power supply module 301 and is inserted into the positioning groove 252. Therefore, when assembling the atomizing module 201 and the battery module 33, the electrode posts 32 are easily aligned, improving production efficiency.

[0040] Electrode posts 32 are mounted at the first end of the bracket 31 and electrically connected to the atomizing module 201. In this embodiment, the electrode posts 32 of the power supply module 301 extend into the electrode slot 232 via the positioning hole 251. The electrode posts 32 and the slot wall of the electrode slot 232 clamp the electronic wire 244, so that the power supply module 301 and the atomizing module 201 are electrically connected. The battery 33 is mounted in the battery mounting slot 311 of the bracket 31 and electrically connected to the electrode posts 32. The bottom cover 34 is sleeved on the second end of the bracket 31 and covers the second end face of the bracket 31. The first end of the bottom cover 34 extends into the receiving cavity 13 and is connected to the bracket 31. The second end of the bottom cover 34 is located outside the outer shell 100. The first end of the bottom cover 34 is provided with a snap-fit ​​groove 341 and a limiting groove 342. The snap-fit ​​protrusion 313 is snapped into the snap-fit ​​groove 341.

[0041] The second elastic connecting ring 35 is fitted onto the limiting groove 342 of the bottom cover 34 and elastically abuts against the cavity wall of the receiving cavity 13, so that the power supply module 301 is detachably connected to the outer shell 100. In other words, the atomizing body 200 and the outer shell 100 are detachably connected through elastic abutment, eliminating the need for threads or snap-fit ​​connections. This not only facilitates production but also makes it easy for users to remove the atomizing body 200. In one embodiment, the second elastic connecting ring 35 is fitted onto the bracket 31 and elastically abuts against the cavity wall of the receiving cavity 13. It is understood that the bottom cover 34 and the outer shell 100 are spaced apart or movably abutted, without the need for threads or snap-fit ​​connections.

[0042] The power supply module 301 also includes an isolation tube 36, an airflow sensor 37, a flexible mounting base 38, and a controller 39. The isolation tube 36 is sleeved on the bracket 31 and connected to the first end of the bottom cover 34. The isolation tube 36 and the bracket 31 combine to form a sealed cavity 361, within which the battery 33 is located. Therefore, when the atomizing body 200 is removed from the outer casing 100, the battery 33 is prevented from falling off the bracket 31. The airflow sensor 37 is mounted on the bracket 31 and located within the sealed cavity 361. The airflow sensor 37 communicates with the atomizing module 201 via a docking groove 302. The flexible mounting base 38 is installed within the battery mounting groove 311.

[0043] The flexible mounting base 38 covers most of the airflow sensor 37 to seal it. The controller 39 is located inside the bottom cover 34 and is electrically connected to the battery 33 and the airflow sensor 37. When a user inhales the aerosol generating device, the airflow sensor 37 detects the user's inhalation signal and sends a trigger signal to the controller 39. The controller 39 controls the battery 33 to supply power to the heating element 243 according to the trigger signal, thereby heating the heating element 243 to heat the vapor-forming substance, causing the vapor-forming substance to vaporize and form vapor.

[0044] In summary, this utility model detachably installs the atomizing body 200 into the receiving cavity 13 and extends it from the opening 14. The atomizing module 201 is detachably connected to the power supply module 301, which extends outside the outer shell 100. The outer wall of the power supply module 301 elastically abuts against the cavity wall of the receiving cavity 13, thus enabling the power supply module 301 to be detachably connected to the outer shell 100. Therefore, when recycling is required, the user can hold the outer shell 100 with one hand and clamp the bottom cover 34 with the other hand, applying axial force to the outer shell 100 to pull the atomizing body 200 out of the outer shell 100. Then, the atomizing module 201 can be separated from the power supply module 301, facilitating classified recycling, being more environmentally friendly, and avoiding resource waste.

[0045] Furthermore, during normal use, if the atomizing material is depleted and the atomizing module 201 needs to be replaced, the atomizing body 200 can be pulled out to replace the new atomizing module 201 without discarding the outer casing 100 and the power supply module 301, thus reducing the environmental burden. Finally, since the power supply module 301 and the outer casing 100 are detachably connected by elastic contact, the problem of difficulty in disassembly caused by threaded or snap-fit ​​connections can be avoided, making this invention more convenient for users.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0047] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution.
