[0002] With the improvement of living standards and people's health awareness, people are paying more and more attention to "healthy" tobacco products. In order to meet the changing consumer demand, major domestic and foreign companies have developed various new heated cigarette products to replace traditional cigarettes.

[0003] At present, the main heating methods for new heated cigarette products are resistance heating and electromagnetic heating. Among them, resistance heating has the disadvantages of low efficiency, long preheating time, large temperature difference between different heating areas of the cigarette, which causes some areas of the cigarette to be burnt while other areas are not fully heated. Electromagnetic heating technology has the advantages of self-heating, fast heating speed and high heat conversion efficiency.

[0004] Correspondingly, the smoking materials of aerosol generating products are currently mainly divided into sheet-type aerosol generating materials and granular aerosol generating materials. Granular aerosol generating materials generally require the tube to be sealed to prevent the particles from falling. Currently, the most common sealing materials are flexible materials, the main purpose of which is to allow the heating needle or heating sheet to pierce and heat the aerosol generating particles. The sealing materials of the prior art are generally flexible materials, which are not conductive and cannot be applied to electromagnetic heating cigarette smoking devices.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] 1. The sealing assembly of the present invention comprises a sealing cap 31 made of magnetic conductive material at one end and a heat-conducting component 32 made of heat-conducting material at one end. The sealing cap 31 is located at the end of the upstream end of the aerosol generating substrate 1, and the downstream end of the heat-conducting component 32 extends toward the inside of the aerosol generating substrate 1. When the sealing cap 31 contacts the electromagnetic heating device, an induced current is generated to generate heat, and the heat is transferred to the heat-conducting component 32. The heat-conducting component 32 heats the aerosol generating substrate 1 to generate aerosol.

[0043] The sealing assembly of the present invention is particularly suitable for aerosol generating products whose aerosol generating materials are granular. The sealing assembly can not only seal the granular aerosol generating materials, but also the sealing cap 31 matches the electromagnetic heating device, generates heat under the action of electromagnetic induction, and the heat conducting component 32 transfers the heat to the aerosol generating substrate. The magnetoelectric aerosol generating product of the present invention is suitable for devices based on the electromagnetic heating principle, and its heating effect is greatly improved and the preheating time is greatly shortened.

[0044] 2.

[0045] 3. The upstream end of the heat-conducting component 32 of the present invention is connected to the sealing cap 31 at a point where there is a heat-insulating component 33. The heat-insulating component 33 prevents the heat generated by electromagnetic induction from being concentrated on the upstream end face of the aerosol generating substrate 1, causing the aerosol generating material at the end to burn under high heat, further causing the various parts of the aerosol generating substrate 1 to be heated unevenly.

[0046] 4. The preparation process of the magnetoelectric aerosol generating product of the present invention is simple and can be completed on the existing assembly production line of the filling type aerosol generating product.

[0047] 5. A heat-conductive material is added to the aerosol generating substrate in the aerosol generating product described in the present invention, so that the aerosol generating substrate is heated more evenly and fully during the heating process, thereby improving the working efficiency of the aerosol generating substrate.
