Description

Technical Field

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

[0002] In aerosol generating devices, it is necessary to improve the heating uniformity of aerosol products in order to ensure that the quality and taste of the generated aerosols meet the user's requirements.

[0003] In existing aerosol generation devices, heat transfer mainly relies on heat conduction. The heating needle is placed at the center of the aerosol-generated product and transfers heat from the inside out.

[0004] However, currently, in order to ensure that the outer area is also fully heated, the temperature of the inner area is usually too high, which makes the inner area prone to overheating and scorching. But lowering the temperature of the inner area may cause insufficient heating of the outer area due to insufficient heat transfer. Utility Model Content

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0042] Please see the appendix Figure 1 -Appendix Figure 3The first aspect of this embodiment relates to an aerosol generating apparatus 10, which is used in conjunction with an aerosol generating article 100. The aerosol generating article 100 may include a mouthpiece section, a connecting section, and a tobacco section capable of generating aerosols. The connecting section is located between the mouthpiece section and the tobacco section and is used to guide the aerosol to the mouthpiece section. The mouthpiece section can be held in the mouth of a user, who can inhale the aerosol by sucking on the mouthpiece. The tobacco section of the aerosol generating article 100 may contain an aerosol generating matrix.

[0043] As used herein, the term "aerosol-generating matrix" refers to a matrix capable of releasing volatile substances to form inhalable aerosols. An aerosol-generating matrix may include tobacco-containing materials 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 it may include non-tobacco materials. The aerosol-generating matrix may also include aerosol-forming agents.

[0044] The aerosol generating article 100 can be generally a rod-shaped structure extending longitudinally. The mouthpiece section can be disposed adjacent to the proximal end of the aerosol generating article 100. The tobacco section can be disposed adjacent to the distal end of the aerosol generating article 100.

[0045] In this embodiment, the aerosol generating device 10 releases heat to the aerosol generating product 100, thereby causing the aerosol generating matrix to produce volatile substances. These volatile substances combine with the air flowing into the aerosol generating matrix to form an aerosol. The air flowing into the aerosol generating matrix and the aerosol generated by the aerosol generating matrix can exit from the proximal end of the aerosol generating matrix and be inhaled into the user's mouth.

[0046] Specifically, the aerosol generating device 10 includes a main body 4, a smoke lifter 1, a heating element 2, and a base 3. The smoke lifter 1 is movably connected to the main body 4 and has a receiving cavity 11 for accommodating a portion of the aerosol generating product 100. The heating element 2 extends into the receiving cavity 11 and is partially inserted into the aerosol generating product 100 to heat the aerosol generating product 100 from the inside. The base 3 is welded to the heating element 2 so that the base 3 heats the aerosol generating product 100 from one end.

[0047] In this embodiment, the aerosol generating product 100 is cylindrical, and the heating element 2 is in the form of a heating needle, upright in the receiving cavity 11. After the aerosol generating product 100 is inserted into the receiving cavity 11, the heating element 2 is inserted into the tobacco segment of the aerosol generating product 100 to achieve heating of the aerosol generating product 100 from the center. With the heating element 2 positioned at the center of the receiving cavity 11, it is naturally located at the center relative to the aerosol generating product 100, and heat is continuously and evenly transferred outward from the center. Furthermore, the base 3 is welded to the heating element 2, and the heating element 2 can conduct heat to the base 3 through thermal conductivity. The base 3 heats the aerosol generating product 100 from one end. The base 3 has a support portion 31 for supporting the cigarette lifter 1 and the aerosol generating product 100.

[0048] This aerosol generating device 10 not only achieves central heating of the aerosol product 100, but also further heats the ends of the aerosol product 100 through thermal conduction, ensuring simultaneous heating of both parts of the aerosol product 100 and improving the heat transfer efficiency of the aerosol product 100. This aerosol generating device 10 effectively addresses the problem in existing technologies where, in order to ensure sufficient heating of the outer area, the temperature of the inner area is often too high, leading to the risk of overheating and scorching of the inner area. However, lowering the temperature of the inner area may result in insufficient heating of the outer area due to inadequate heat transfer. It avoids heat accumulation in the inner area, improves the heating uniformity of the aerosol product 100, ensures the quality and taste of the generated aerosol, and enhances the user experience.

[0049] Please see the appendix Figure 4 -Appendix Figure 6 Optionally, the base 3 is provided with a through hole 33 through which the heating element 2 passes.

[0050] Specifically, the heating element 2 includes, but is not limited to, materials such as stainless steel, aluminum (alloy), and copper (alloy). The support portion 31 is a circular plate structure with a through hole 33 at its center for the heating element 2 to pass through. The through hole 33 is circular. The inner diameter of the through hole 33 is larger than the outer diameter of the heating element 2, creating an annular gap 34 between the inner wall of the through hole 33 and the outer wall of the heating element 2, with the gap 34 ranging from 0 to 0.2 mm. The support portion 31 has a heating surface 311 opposite to the aerosol generating product 100 and a connecting surface 312 facing away from it. The distance between the heating surface 311 and the connecting surface 312 is 0.15 mm to 0.80 mm, meaning the wall thickness of the support portion 31 is 0.15 mm to 0.80 mm, providing sufficient support strength while also ensuring adequate heat conduction.

[0051] Please refer to the appendix. Figure 5Furthermore, the connecting surface 312 is connected to the outer wall of the heating element 2 by an annular welding part 313, which is used to seal the gap 34.

[0052] Specifically, the support portion 31 includes a heating surface 311 and a connecting surface 312. The heating surface 311 can abut against the aerosol generating product 100, or other heat-conducting components can be sandwiched between it and the aerosol generating product 100. The welding portion 313 is welded circumferentially between the connecting surface 312 and the heating element 2. In this embodiment, a full circumferential weld is used to seal the gap 34, preventing debris from the aerosol generating product 100 from falling into the bottom circuit through the gap 34, thereby avoiding any impact on the circuit connection. In addition, sealing the gap 34 with a full circumferential weld can also prevent air from entering the receiving cavity 11 through the gap 34, so that the aerosol generating device 10 maintains a certain suction resistance.

[0053] Please see the appendix Figure 5 Optionally, the base 3 is provided with a plurality of connecting parts 32 at intervals along the circumference, and the base 3 is connected to the main body 4 through the connecting parts 32.

[0054] Specifically, four connecting parts 32 are arranged at intervals along the circumference. Connecting holes are provided on the connecting parts 32, and threaded fasteners can be screwed into the main body 4 through the connecting holes to achieve the effect of fixing and stabilizing the base 3.

[0055] Please continue to refer to the appendix. Figure 2 and attached Figure 3 Optionally, the smoke extractor 1 includes a first heat-conducting part 12, which is thermally connected to the base 3. The first heat-conducting part 12 is used to heat one end of the aerosol generating product 100.

[0056] Specifically, the first heat-conducting part 12 abuts against one end of the aerosol generating product 100, and at the same time, the first heat-conducting part 12 is thermally connected to the base 3, so that the heating element 2 transfers heat to the first heat-conducting part 12 through the base 3, and then heats one end of the aerosol generating product 100 through the first heat-conducting part 12. The first heat-conducting part 12 can be used to form the bottom of the receiving cavity 11. In addition to heating the aerosol generating product 100, it can also support the aerosol generating product 100. After the aerosol generating product 100 is heated, the aerosol generating product 100 is separated from the heating element 2 by lifting the smoke lifter 1.

[0057] Furthermore, the smoke extractor 1 also includes a second heat-conducting part 13 that is heat-conductingly connected to the first heat-conducting part 12. The first heat-conducting part 12 and the second heat-conducting part 13 jointly define a portion of the receiving cavity 11. The second heat-conducting part 13 is used to heat the outer periphery of the aerosol generating article 100.

[0058] Specifically, the first heat-conducting part 12 is connected to one end of the second heat-conducting part 13. The two can be an integral structure or connected by welding. The second heat-conducting part 13 is a sleeve structure to form a receiving cavity 11. The second heat-conducting part 13 can heat the circumferential outer wall of the aerosol generating product 100 by contacting it, thereby achieving simultaneous heating in three areas: the center, the end, and the outer periphery of the aerosol generating product 100. This significantly improves the uniformity of heating of the aerosol generating product 100, ensures the quality and taste of the generated aerosol, and enhances the user experience.

[0059] Optionally, the main body 4 is provided with a heat-insulating component, which is located on the side of the base 3 away from the aerosol generating product 100. The heat-insulating component is either in contact with or spaced apart from the base 3.

[0060] Specifically, the heat-insulating component can be made of a material with low thermal conductivity, such as PEEK, PEEK+GF, silicon dioxide, zirconium oxide, etc.

[0061] In this embodiment, by providing a heat-insulating component, heat can be prevented from being transferred from the bottom to the areas that make up the circuit or other non-heated areas.

[0062] Please refer to the appendix again. Figure 1 and attached Figure 2 The second aspect of this embodiment also relates to an aerosol generation system 20, which includes an aerosol generation article 100 and an aerosol generation device 10, wherein the aerosol generation device 10 heats the aerosol generation article 100 to generate aerosol.

[0063] In this aerosol generation system 20, the aerosol generation device 10 uses electrical energy to convert into heat energy to heat the tobacco segment of the aerosol generation product 100. The generated substance combines with air to form an aerosol for the user to inhale. The aerosol generation product 100 is a replaceable consumable in this aerosol generation system 20, and various flavors can be provided to the user based on different types of aerosol generation products 100. Based on this aerosol generation device 10, the aerosol generation system 20 can achieve sufficient heating inside and outside the aerosol generation product 100, ensuring uniform heating, thereby guaranteeing the quality of aerosol generation and improving the user experience.
