Description

Technical Field

[0001] This disclosure relates to the field of aerosol generation technology, and more specifically, to an aerosol generation apparatus and an aerosol generation system. Background Technology

[0002] Traditional cigarettes contain dozens of carcinogens, such as tar, in the smoke, which poses a significant threat to human health. Furthermore, the smoke creates secondhand smoke, which can also harm those nearby. The heated but non-combustible aerosol generator uses a central heating needle to provide heat from the inside out, baking the tobacco and releasing only nicotine and flavor compounds for the user to inhale, thus minimizing the release of other harmful substances.

[0003] Because the central heating element needs to be inserted into the cigarette, its heating area is strictly limited by its external dimensions. Heat is transferred radially from the center outward through the tobacco. The temperature of the inner area of ​​the cigarette is higher than that of the outer area. If the tobacco in the inner area is not charred, the tobacco in the outer area will not be sufficiently heated, resulting in insufficient aroma release and smoke production, which affects the user's smoking experience. Summary of the Invention

[0004] To address the issue of insufficient heating of tobacco shreds in the outer region of aerosol-generated products, resulting in insufficient release of tobacco aroma and smoke volume, thus affecting the user's smoking experience, this disclosure provides an aerosol generating device and an aerosol generating system.

[0042] This disclosure provides an aerosol generating device 10, such as... Figure 1 As shown, it includes a main body 1, a smoke lifter 2, and a heating component 3.

[0043] The main body 1 and the smoke lifter 2 are detachably connected. The smoke lifter 2 has a receiving cavity 21 for accommodating the aerosol generating product 20. It should be noted that after the aerosol generating product 20 is inserted into the receiving cavity 21, the smoke lifter 2 can move the aerosol generating product 20 together, and the smoke lifter 2 can assist the user in lifting the smoke.

[0044] The heating element 3 extends into the receiving cavity 21 to heat the aerosol generating article 20 to produce aerosol. The heating element 3 may be needle-shaped. After the aerosol generating article 20 is inserted into the receiving cavity 21, the needle-shaped heating element 3 can be inserted into the aerosol generating article 20. The needle-shaped heating element 3 can heat and bake the aerosol generating article 20 from the inside, so that the aerosol generating article 20 produces aerosol.

[0045] The smoke lifter 2 includes a top cover 22, an elastic element 23 and a sleeve 24 connected in sequence. The sleeve 24 defines a receiving cavity 21. One end of the elastic element 23 abuts against the top cover 22, and the other end of the elastic element 23 abuts against the sleeve 24, so that the sleeve 24 abuts against the heating component 3.

[0046] In the aerosol generating device 10 of this disclosure, one end of the elastic element 23 of the smoke lifter 2 abuts against the top cover 22, and the other end of the elastic element 23 abuts against the sleeve 24, so that the sleeve 24 abuts against the heating component 3, thereby facilitating the transfer of heat from the heating component 3 to the sleeve 24, so that the sleeve 24 bakes the outer area of ​​the aerosol generating product 20, allowing the aerosol generating product 20 to release sufficient smoke and vapor, so that the user can obtain a good smoking experience.

[0047] In one embodiment of this disclosure, such as Figures 2-3 As shown, the smoke lifter 2 also includes a bracket 25, which is fixed to the top cover 22. The bracket 25 and the top cover 22 together define an elastic cavity 231, and an elastic element 23 is disposed in the elastic cavity 231. The elastic cavity 231 is used to accommodate the elastic element 23, which can deform in the elastic cavity 231, so that the sleeve 24 abuts against the heating assembly 3.

[0048] In one embodiment of this disclosure, the bracket 25 is fixed to the top cover 22 by screws. In other embodiments of this disclosure, the bracket 25 and the top cover 22 can be connected by means of snap-fit ​​or the like, so that the bracket 23 and the top cover 22 are fixedly connected.

[0049] In one embodiment of this disclosure, the sleeve 24 has a protrusion 241 at one end facing the top cover 22. The protrusion 241 is disposed in the elastic cavity 231 and abuts against the elastic member 23. A certain amount of space is reserved in the elastic cavity 231 so that the protrusion 241 can move within the elastic cavity 231.

[0050] In one embodiment of this disclosure, the distance between the protrusion 241 and the top cover 22 is 0.1mm-5.0mm, and the distance between the protrusion 241 and the bracket 25 is 0.1mm-5.0mm, so that the protrusion 241 can move within the elastic cavity 231, and the sleeve can abut against the base 32 when the relevant parts fluctuate within the normal tolerance range.

[0051] In one embodiment of this disclosure, the bracket 25 has a through hole 251 through which the sleeve 24 passes.

[0052] In one embodiment of this disclosure, the outer diameter of the protrusion 241 is larger than the inner diameter of the through hole 251, such that the protrusion 241 on the sleeve 24 is located inside the elastic cavity 231.

[0053] In one embodiment of this disclosure, the elastic element 23 is a spring, a sheet, foam, silicone, or rubber. In one embodiment of this disclosure, in order for the sleeve 24 to abut against the heating assembly 3 under the force of the elastic element 23, the elastic element 23 is installed in the elastic cavity 231 and is in a compressed state, so that the elastic element 23 can apply an external force to the sleeve 24, causing the sleeve 24 to abut against the heating assembly 3. In one embodiment of this disclosure, the elastic element 23 is a spring. Before the cigarette lifter 2 is installed to the main body 1, the elastic element 23 abuts against the protrusion 241, causing the sleeve 24 to abut against the bracket 25; after the cigarette lifter 2 is installed to the main body 1, the sleeve 24 abuts against the base 32, at which time the elastic element 23 is compressed, and the protrusion 241 is located between the top cover 22 and the bracket 25.

[0054] In one embodiment of this disclosure, there are two elastic elements 23, so that both ends of the sleeve 24 are subjected to abutment force, making the force on both ends of the sleeve 24 more uniform.

[0055] In one embodiment of this disclosure, the sleeve 24 includes an upper section 242 and a lower section 243 connected to the upper section 242. The upper section 242 and the lower section 243 together define a receiving cavity 21, and the lower section 243 is a heat-conducting element. The heat from the heating component 3 can be conducted to the lower section 243 to heat the aerosol generating article 20. It should be noted that the lower section 243 can surround the outer periphery of the aerosol generating article 20, and the lower section 243 receiving heat from the heating component 3 can heat the aerosol generating article 20. In this way, the heating component 3 and the lower section 243 can heat the aerosol generating article 20 from both the center and the outer periphery, so that the aerosol generating article 20 can be fully baked.

[0056] In one embodiment of this disclosure, the cigarette holder 2 is movably connected to the main body 1. The aerosol generating product 20 is inserted into the receiving cavity 21 and heated by the heating component 3 to generate aerosol. After the user finishes inhaling, the cigarette holder 2 can be separated from the main body by the user applying external force, thereby separating the inhaled aerosol generating product 20 from the heating component 3. Since the inhaled aerosol generating product 20 will produce some residue, the cigarette holder 2 can better separate the inhaled aerosol generating product 20 from the heating component 3, preventing the residue from falling around the heating component 3. This avoids the residue being over-baked and producing a burnt smell when the user inhales again.

[0057] In one embodiment of this disclosure, the main body 1 and the cigarette holder 2 are detachably connected by magnetic attraction. In one embodiment of this disclosure, the main body 1 includes a first magnetic element, and the cigarette holder 2 includes a second magnetic element. In one embodiment of this disclosure, there are two first magnetic elements and two second magnetic elements. In one embodiment of this disclosure, the materials of the magnetic attraction structure include, but are not limited to, rubidium boron magnets, electromagnets, and materials containing iron.

[0058] In one embodiment of this disclosure, the magnetic attraction between the main body 1 and the cigarette lifter 2 is greater than or equal to the abutment force of the elastic member 23 against the sleeve 24, so that when the main body 1 and the cigarette lifter 2 are magnetically connected, the sleeve 24 and the top cover 22 will not separate due to the elastic force of the elastic member 23. In one embodiment of this disclosure, the direction of the magnetic attraction between the main body 1 and the cigarette lifter 2 is parallel to the direction of the abutment force of the elastic member 23 against the sleeve. In one embodiment of this disclosure, both the direction of the magnetic attraction between the main body 1 and the cigarette lifter 2 and the direction of the abutment force of the elastic member 23 against the sleeve 24 are parallel to the insertion direction of the aerosol generating article 20.

[0059] In one embodiment of this disclosure, the end of the aerosol generating device 10 closest to the user is the proximal end, and the end furthest from the user is the distal end. In one embodiment of this disclosure, the upper section 242 of the cigarette lifter 2 is located at the proximal end, and the lower section 243 of the cigarette lifter 2 is located at the distal end.

[0060] In one embodiment of this disclosure, the heating assembly 3 includes a heating needle 31 and a base 32, the heating needle 31 extending into the receiving cavity and the base 32 abutting against the sleeve 24.

[0061] In one embodiment of this disclosure, the base 32 is a heat-conducting element. In one embodiment of this disclosure, the base 32 and the lower section 243 are in contact and thermally connected. In one embodiment of this disclosure, the heat generated by the heating needle 31 is conducted to the base 32, and then from the base 32 to the lower section 243. In one embodiment of this disclosure, a portion of the heat generated by the heating needle 31 is directly conducted to the lower section 243, and another portion is conducted to the base 32, and then from the base 32 to the lower section 243.

[0062] In one embodiment of this disclosure, the base 32 is made of stainless steel, aluminum, aluminum alloy, copper, copper alloy, or graphene. The base 32 is made of a material with high thermal conductivity to facilitate heat conduction between the base 32 and the heating needle 31, and between the base 32 and the lower section 22.

[0063] In one embodiment of this disclosure, the lower section 243 comprises stainless steel, aluminum, aluminum alloy, copper, copper alloy, or graphene. The use of a material with high thermal conductivity in the lower section 243 allows for better heat conduction from the heating component 3 to the lower section 22. Furthermore, the high thermal conductivity of the lower section 243 also results in a more uniform heat distribution on its surface, ensuring that the aerosol-generating article 20 can be baked evenly.

[0064] In one embodiment of this disclosure, the upper section 242 is a heat insulation component. On the one hand, the heat insulation component can prevent heat from the lower section 243 from being conducted to the proximal end of the aerosol generating device 10 near the user, thus preventing the user from being burned; on the other hand, the heat insulation component can prevent heat from the lower section 243 from being conducted to the non-tobacco section area of ​​the aerosol generating article 20, thus avoiding heat waste.

[0065] In one embodiment of this disclosure, the upper section 242 and the lower section 243 are snapped together, so that the upper section 242 and the lower section 243 can be made of materials with different thermal conductivity and are structurally tightly connected, so that the smoke lifter 2 and the aerosol generating product 20 can form an air passage, and the user can obtain a suitable suction resistance.

[0066] One embodiment of this disclosure also provides an aerosol generation system 100, such as Figures 4-6 As shown, it includes an aerosol generating article 20 and the aforementioned aerosol generating device 10. The aerosol generating device 10 heats the aerosol generating article 20 to generate aerosol.

[0067] In one embodiment of this disclosure, the tobacco segment of the aerosol-generating article 20 may have an aerosol-generating matrix. As used herein, the term "aerosol-generating matrix" refers to a matrix capable of releasing volatile substances to form an inhalable aerosol. The aerosol-generating matrix may include tobacco-containing material containing volatile tobacco flavor compounds that are released from the substrate upon heating. Specifically, the aerosol-generating matrix may be a tobacco-containing aerosol-generating matrix or an aerosol-generating matrix containing solid tobacco. Alternatively, the aerosol-generating matrix may include non-tobacco materials. The aerosol-generating matrix may also include an aerosol-forming agent. Examples of suitable aerosol-forming agents are glycerol and propylene glycol.

[0068] As needed, the aerosol generating matrix may contain additional tobacco or non-tobacco volatile aroma compounds released when the aerosol generating matrix is ​​heated. The aerosol generating matrix may also contain microcapsules, which may contain additional tobacco or non-tobacco volatile aroma compounds, and such microcapsules may melt during heating of the solid aerosol generating matrix.

[0069] It should be noted that the preferred embodiments of this disclosure are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
