Description

Technical Field

[0001] The present application relates to the field of aerosol generation technology, and in particular to aerosol generating products and aerosol generating systems. Background Art

[0002] Aerosol generating products generally include a smoking section and a filter section. When in use, the smoking section is heated to generate aerosol which is output through the filter section. In related technologies, in order to increase the flavor, etc., a flavor-carrying section is usually provided downstream of the smoking section. The flavor of the flavor-carrying section is brought out by the hot air flow of the aerosol. The hot air flow of the aerosol gradually cools down after flowing out from the smoking section, so that the flavor of the flavor-carrying section is not fully stimulated and the fragrance cannot be released well. Moreover, the fragrance-carrying section is unstable when heated. When the temperature is too low, the fragrance cannot be released and the continuity of the fragrance is poor, which affects the user experience. Utility Model Content

The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0026] Existing heat-not-burn tobacco products have the problem that the aroma-carrying segment is carried out by the aerosol hot air flow, the temperature is low, the heating is insufficient, and the aroma is not completely stimulated. In addition, the aroma-carrying segment is unstable when heated. When the temperature is too low, the aroma cannot be produced, and the aroma continuity is poor.

[0027] In the present application, a heat conductor is added between the fragrance carrying section and the smoke generating section, and the heat energy of the smoke generating section is transferred to the fragrance carrying section through the heat conductor, so that the temperature of the fragrance carrying section is higher, the fragrance is more fully stimulated, and the continuity is better.

[0028] Please refer to Figure 1 to Figure 2In one embodiment, an aerosol generating product is provided, comprising: a smoking segment 200, a housing 100, a fragrance carrying segment 220 and a heat conducting member 210; the smoking segment 200, the fragrance carrying segment 220 and the heat conducting member 210 are all arranged in the housing 100; the heat conducting member 210 is arranged between the smoking segment 200 and the fragrance carrying segment 220, and the two opposite sides of the heat conducting member 210 are in contact with the smoking segment 200 and the fragrance carrying segment 220 respectively. By adding a heat conducting member 210 between the fragrance carrying segment 220 and the smoking segment 200, the heat energy of the smoking segment 200 is transferred to the fragrance carrying segment 220 through the heat conducting member 210, and the fragrance carrying segment 220 is heated by the heat energy transferred by the heat conducting member 210 and the high-temperature aerosol generated by the smoking segment 200 at the same time, which can fully heat the fragrance of the fragrance carrying segment 220 itself.

[0029] In one embodiment, the positions of the smoke-generating segment 200 and the aroma-carrying segment 220 can be interchanged, that is, the end of the smoke-generating segment 200 away from the aerosol output abuts against the second end surface 215 of the heat-conducting member 210, and the aroma-carrying segment 220 abuts against the first end surface 214 of the heat-conducting member 210, so that the heat energy of the smoke-generating segment 200 itself is transferred to the aroma-carrying segment 220 through the heat-conducting member 210.

[0030] It can be understood that the thickness of the heat conducting member 210 is determined by design requirements, materials, thermal conductivity, and other factors. Therefore, the thickness of the heat conducting member 210 is not fixed.

[0031] Please refer to Figure 1 and Figure 3 In one embodiment, the heat conductive member 210 is a mesh structure, or the heat conductive member 210 is provided with at least one through hole 213 connecting the smoking section 200 and the fragrance carrying section 220; the heat conductive member 210 separates the smoking section 200 and the fragrance carrying section 220, and the heat conductive member has the function of separating the fragrance carrying section from the smoking section and transferring the heat of the smoking section to the fragrance carrying section.

[0032] It should be understood that substances located in the fragrance carrying section 220 or in the smoke generating section 200 cannot pass through the mesh structure or the through holes 213 .

[0033] In one embodiment, the through hole may also be in other shapes, such as star-shaped, circular, etc.

[0034] Please refer to Figure 1 and Figure 3 In one embodiment, a heat-conductivity enhancement structure 211 is further included; the heat-conductivity enhancement structure 211 is extended from the heat-conducting member 210 to the smoke-generating segment 200 and is in surface contact with the smoke-generating segment 200; and the heat-conductivity enhancement structure 211 is connected or integrated with the heat-conducting member 210. The internal temperature of the smoke-generating segment 200 is higher than the external surface temperature, and the heat-conductivity enhancement structure is inserted into the smoke-generating segment 200 to improve the heating efficiency.

[0035] In one embodiment, the length of the heat-conductivity enhancement structure 211 is less than or equal to the length of the smoking segment 200 .

[0036] Please refer to Figure 1 In one embodiment, the heat conduction enhancement structure 211 is inserted into the smoke generating section 200 , or the heat conduction enhancement structure 211 is attached to the outer peripheral surface of the smoke generating section 200 .

[0037] In one embodiment, the heat conductivity enhancement structure may extend throughout the entire smoking section 200 .

[0038] Please refer to Figure 4 In one embodiment, the thermal conductivity enhancement structures 211 are multiple and are arranged at intervals along the circumference of the aerosol generating article. In one embodiment, the multiple thermal conductivity enhancement structures 211 can be evenly arranged along the circumference of the smoking section 200. Multiple thermal conductivity enhancement structures 211 are conducive to improving the efficiency of the heat conductive member 210 absorbing heat energy from the smoking section 200, and the thermal conductivity enhancement structures arranged at intervals along the circumference are conducive to more uniform heat transfer to the heat conductive member 210, so that the overall temperature of the heat conductive member 210 is uniform.

[0039] Please refer to Figure 5 In one embodiment, an extension portion 212 is provided at one end of the heat-conducting enhancement structure 211 away from the heat-conducting member 210, and the extension portion 212 extends from the heat-conducting enhancement structure 211 to the inner side of the smoke-generating section 200. The extension portion 212 can have a larger area to transfer heat to the heat-conducting enhancement structure, thereby improving the heating efficiency of the heat-conducting member 210. In one embodiment, the extension portion 212 is in a mesh shape, which increases the contact area with the smoke-generating section 200 and improves the heat transfer efficiency while ensuring that the gas flow is not blocked.

[0040] Please refer to Figure 1 In one embodiment, the aerosol generating product is further provided with a heat insulating layer 120; the heat insulating layer 120 is arranged between the periphery of the heat conductive member 210 and the outer shell 100, separating the heat conductive member 210 from the outer shell 100, and the heat insulating layer 120 can block heat from being transferred to the outside, thereby improving the heating efficiency.

[0041] In one embodiment, the heat insulating layer 120 may be disposed on the inner wall of the outer shell 100 , or the heat insulating layer 120 and the outer shell 100 may be integrally disposed.

[0042] Please refer to Figure 2 In one embodiment, a gap 130 is provided between the housing 100 and the heat-conducting enhancement structure. The gap 130 is mainly used for heat insulation to avoid paper paste gas caused by high-temperature baking of the paper tube wall and improve the user experience.

[0043] Please refer to Figure 1 In one embodiment, the heat conductive member 210 is made of metal; and / or the heat conductive enhancement structure 211 is made of metal; and / or the heat conductive enhancement structure 211 is made of magnetic induction heating material. Metal has a high thermal conductivity, high thermal conductivity efficiency, and a relatively high melting point, and will not melt. It is understandable that the heat conductive enhancement structure can also be other materials, such as graphite, thermal conductive ceramics, etc. The magnetic induction heating material can be heated in the air by an external power source to generate heat.

[0044] Please refer to Figure 4 and Figure 5 In one embodiment, the thermal conductivity enhancement structure 211 is a sheet structure, a strip structure or a ring structure.

The high-temperature aerosol and the heat conducting member 210 heat the fragrance in the aroma carrying section 220 at the same time, so that the fragrance of the fragrance in the aroma carrying section 220 is stimulated, and the aerosol mixed fragrance passes through the cooling section 230, and the cooling section 230 cools down the high-temperature aerosol and the fragrance mixed gas, and the mixed gas passes through the filtering section 240, and after filtering out impurities, the mixed gas becomes an aerosol that is easy to use.

[0046] In one embodiment, the positions of the cooling section 230 and the filtering section 240 can be swapped, that is, the smoking section 200, the heat conducting element 210, the fragrance carrying section 220, the filtering section 240 and the cooling section 230 are sequentially arranged in the outer shell 100 of the aerosol generating product.

[0047] Please refer to Figure 6 In one embodiment, an aerosol generating system is provided, comprising an aerosol generating device and an aerosol generating product in any of the above embodiments.

[0048] In one embodiment, the aerosol generating device includes a heating element 250. When the aerosol generating product is assembled on the aerosol generating device, the heating element is inserted into the aerosol generating product and contacts the heat conductive element 210 of the aerosol generating product. The heating element 250 is inserted into the smoking segment 200. The heating element 250 directly heats the smoking segment 200 to generate aerosol. Part of the heat of the heating element 250 is transferred to the fragrance carrying segment 220 through the heat conductive element 210.

[0049] It is understandable that in other embodiments, the heating element 250 may not be inserted into the smoking segment 200.
