[0036] Example 1

[0037] The embodiments of this application provide an aerosol generating article 1000, which is mainly used to form an aerosol after heating for user use, and can improve the problem of uneven heating during the heating process.

[0038] Combination Figure 1 and Figure 2As shown, the aerosol generating article 1000 provided in this embodiment includes a smoke-generating section. The smoke-generating section includes an aerosol matrix 1100 and a heat-insulating layer 1200. The aerosol matrix 1100 is a columnar molded part. Both the aerosol matrix 1100 and the heat-insulating layer 1200 are breathable. The heat-insulating layer 1200 is sleeved around the aerosol matrix 1100, and along the axial direction of the aerosol generating article 1000, the projection surface of the heat-insulating layer 1200 coincides with the projection surface of the aerosol matrix 1100. The aerosol generated by heating the aerosol matrix 1100 can pass through the heat-insulating layer 1200 along the axial direction of the aerosol generating article 1000. This application provides thermal insulation by covering the aerosol matrix 1100 with the insulation layer 1200, thereby reducing heat loss from the aerosol matrix 1100 and ensuring more uniform heating of all areas during the heating process. This ensures that the aerosol matrix 1100 is fully heated, reducing waste and preventing scorching in some areas due to uneven heating. Furthermore, the breathable insulation layer 1200 provides a channel for the aerosol generated by the heating of the aerosol matrix 1100, facilitating inhalation by the user.

[0039] In some embodiments, the aerosol matrix 1100 is manufactured by stamping or molding processes, and the aerosol matrix 1100 has a first predetermined cross-section.

[0040] It is understood that, since the aerosol matrix 1100 is a columnar body made by stamping or molding, the first preset cross-sectional shape can be adjusted to any one of the following shapes, such as ellipse, polygon, or honeycomb with axial holes, according to actual needs.

[0041] In some embodiments, the aerosol matrix 1100 is a solid smoke-generating material, and the raw materials of the aerosol matrix 1100 include one or more of the aroma compounds of tobacco plants and non-tobacco plants and smoke-generating agents.

[0042] For example, the tobacco plant is tobacco powder. The aroma compounds from the non-tobacco plants include essential oils and extracts from aromatic plants and synthetic fragrances. The essential oils and extracts from aromatic plants include commonly used plant essential oils such as laurel leaf oil, rose oil, and clove oil. The synthetic fragrances, such as cinnamic acid, have excellent aroma-preserving properties; as a fragrance ingredient, they can make the aroma of the main fragrance more fragrant and volatile, and various esters of cinnamic acid can be used as fixatives.

[0043] In some embodiments, the tobacco plant, the aroma compounds of the non-tobacco plant, and the smoke-generating agent are pressed into tablets using an anhydrous pressing machine, so that the aerosol matrix 1100 has the characteristics of loose texture, low relative density, light weight, good adsorption effect, and strong ability to load aroma substances.

[0044] Combination Figure 2 As shown, in some embodiments, the aerosol matrix 1100 includes a first end 1110 and a second end 1120.

The heating element 2200 is disposed within the aerosol matrix 1100. The heating element 2200 is used to heat the aerosol matrix 1100 to generate aerosol. The heating element 2200 is located between the first end 1110 and the second end 1120, and is located on the central axis of the aerosol matrix 1100 to ensure uniform heating of the aerosol matrix 1100. The heating element 2200 is an induction heating element 2200, and it is used in conjunction with a non-contact electromagnetic induction element 2300 to heat the aerosol matrix 1100.

[0046] For example, the induction heating element 2200 is a metal sheet. The non-contact electromagnetic induction element 2300 is an electromagnetic coil.

[0047] Combination Figure 1 and Figure 2 As shown, in other embodiments, the aerosol generating article 1000 does not contain a heating element 2200, and the heating device 2000 includes the heating element 2200. ， The heating element 2200 ， As a sheet heater, when the aerosol matrix 1100 is inserted into the heating device 2000, the heating element 2200... ， Inserted into the aerosol matrix 1100, thereby heating the aerosol matrix 1100. Exemplarily, the heater is a ceramic sheet coated with a zirconium oxide.

[0048] Combination Figure 2 andFigure 3 As shown, in some embodiments, the insulation layer 1200 is provided with an opening 1230 that matches the shape of the aerosol matrix 1100, and the aerosol matrix 1100 is housed in the opening 1230 so that part of the aerosol matrix 1100 is exposed from the insulation layer 1200.

[0049] Combination Figure 3 As shown, in some embodiments, the insulation layer 1200 includes a first insulation portion 1210 and a second insulation portion 1220.

The second insulation portion 1220 is connected to the first insulation portion 1210 to form the open cavity 1230, and the second insulation portion 1220 is attached to the second end portion 1120.

[0052] It is understood that the insulation layer 1200 is wrapped around the aerosol matrix 1100 to better achieve the effect of heat insulation, so that the heating element 2200 ， The transferred heat circulates continuously within the insulation layer 1200, thereby making the entire aerosol-generating product 1000 more evenly heated.

[0053] In some embodiments, the insulation layer 1200 has a second preset cross-section. The area ratio of the first preset cross-section to the area of ​​the second preset cross-section is 6-7:3-4, that is, the second preset cross-section accounts for 30%-40% of the cross-section of the aerosol generating article 1000.

[0054] In some embodiments, the raw material of the insulation layer 1200 includes one or more of tobacco shreds, flakes, or granules and a mixture of bio-based polysaccharides. The tobacco shreds, flakes, or granules have a good ability to load aroma substances, and the aroma substances include, but are not limited to, fragrances and flavorings with herbal, fruit, and floral characteristics, such as strawberry flavoring, mango flavoring, cola flavoring, jasmine flavoring, tea flavoring, etc., which will not be listed here.

[0055] For example, the bio-based polysaccharide includes one or more of mannitol, sodium alginate, chitosan, and chitin. The insulation layer 1200 can effectively improve the thermal stability of the smoke-generating section and inhibit the pyrolysis process, thereby improving the heat resistance performance.

[0056] In some embodiments, the raw material of the insulation layer 1200 includes a mixture of bio-based polysaccharides. In some embodiments, the raw material of the insulation layer 1200 includes tobacco shreds, flakes, or granules.

[0058] It is understood that when the aerosol generating product 1000 is in use, the aerosol matrix 1100 and the insulation layer 1200 can simultaneously emit fragrance. The assembly method in which the aerosol matrix 1100 and the insulation layer 1200 are wrapped inside and out allows the aerosol generating product 1000 to achieve the effects of assisting in fragrance enhancement and joint fragrance release during use, and also ensures that the smoke-generating section is heated evenly, while locking in the fragrance substances inside the smoke-generating section, and also playing a role in moisture prevention and moisture retention.

[0059] In some embodiments, the aroma-producing components in the insulation layer 1200 account for 20% to 40% of the mass percentage of the aerosol-generating article 1000, and the aroma-producing components in the aerosol matrix 1100 account for 40% to 60% of the mass percentage of the aerosol-generating article 1000.

[0060] In other embodiments, the aroma-producing components in the insulation layer 1200 account for 20% to 40% of the mass percentage of the aerosol-generated article 1000, or the aroma-producing components in the aerosol matrix 1100 account for 40% to 60% of the mass percentage of the aerosol-generated article 1000.

[0062] In some embodiments, there is a preset distance between the filter element 3000 and the smoke-generating section, and the portion between the filter element 3000 and the smoke-generating section is a cooling section for aerosol cooling.

[0063] The aerosol generating article 1000 provided in this application assembles the aerosol matrix 1100 and the heat insulation layer 1200 by wrapping them inside and out. On the one hand, this allows the heating element 2200 to... ， The transferred heat circulates continuously within the insulation layer 1200, thereby making the entire aerosol generating product 1000 more evenly heated and improving the phenomenon of scorching in some areas of the aerosol matrix 1100 due to uneven heating. On the other hand, the aerosol matrix 1100 and the insulation layer 1200 can achieve the effects of assisting in aroma enhancement and joint aroma release, and can lock in the aroma substances inside the smoke-generating section, thus playing a role in moisture prevention and moisture retention.
