Title:
AEROSOL GENERATING DEVICE AND AEROSOL GENERATING ARTICLE THEREOF, AND HEATING ASSEMBLY AND SUSCEPTOR
Document Type and Number:
WIPO Patent Application WO/2024/041127
Kind Code:
A1
Abstract:
The present invention relates to an aerosol generating device and an aerosol generating article thereof, and a heating assembly and a susceptor. The susceptor comprises a heating layer, a heat conduction layer and a temperature sensing layer, wherein the heating layer is used for generating heat under the action of a changing magnetic field; the heat conduction layer is arranged between the heating layer and the temperature sensing layer, and the heat conduction layer is used for conducting to the temperature sensing layer the heat generated by the heating layer; and the temperature sensing layer is used for changing a magnetic permeability on the basis of the temperature of the susceptor. The heating assembly comprises a susceptor and a coil surrounding the susceptor. The aerosol generating article comprises an aerosol generating matrix and a susceptor. The aerosol generating device comprises a power source assembly and a heating assembly or an aerosol generating article. In the present invention, a magnetic permeability of a temperature sensing layer changes on the basis of the temperature of a susceptor, a heat conduction layer is added between the temperature sensing layer and a heating layer, different materials are respectively compounded to form the susceptor with a multilayer structure, and the structure of the susceptor is simple, thereby simplifying a temperature measurement of the susceptor; and the corrosion resistance of the materials is strong, thereby facilitating the accurate temperature control of the susceptor, and improving the heating efficiency.
