Title:
HEATING ASSEMBLY AND AEROSOL GENERATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/116536
Kind Code:
A1
Abstract:
A heating assembly (2) and an aerosol generating device. The heating assembly comprises a matrix (21) made of a metal, wherein the matrix (21) is a heat radiation element for radiating heat to heat a suckable product (1) so as to enable the suckable product (1) to generate an aerosol; the matrix (21) is doped with a non-metal element; and along the depth direction with the radiating surface of the matrix (21) as a starting point, the distribution density of the non-metal element at a first depth is greater than the distribution density of the non-metal element at a second depth, the second depth being greater than the first depth. A non-metal element is present in the surface layer, having a certain thickness, of the matrix (21) made of a metal, and the surface layer of the metal matrix (21) is modified by using the non-metal element, such that the emissivity of the heat radiation of the metal matrix (21) is increased. Moreover, the surface layer of the metal matrix (21) modified by the non-metal element has an appropriate heat conductivity coefficient, and thus has a good soaking effect and a high wear resistance and does not fall off.
