Abstract

The invention provides an atomization assembly for an electronic cigarette, a preparation method of the atomization assembly and an electronic cigarette. The atomization assembly comprises a porous body and a heating material layer; the porous body is used for absorbing aerosol to form a substrate; the heating material layer is combined to at least one part of the surface of the porous body; the heating material layer is formed by a composite material comprising a ceramic material and an electric heating metal material, wherein the ceramic material and the material forming the porous body have at least one same material component. According to the atomization assembly, the heating material layer prepared by compounding the ceramic material and the electric heating metal material is adopted, and the ceramic material plays a role in framework supporting, so that on one hand, the electric heating metal material is prevented from permeating or filling the pore channels of the porous body, and the permeability of the pore channels of the porous body is kept to a certain extent; on the other hand, the form of the heating material layer and the uniform stability of resistance are improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of electronic cigarettes, and in particular to an atomizing component for an electronic cigarette, a method for preparing the atomizing component, and an electronic cigarette. Background technique [0002] The core component of the electronic cigarette product is an atomizer that heats the aerosol-forming substrate to atomize it to generate an aerosol. The function of the atomizer is mainly based on the atomization component; An atomizing component includes a porous body for absorbing and conducting an aerosol-forming substrate, and a heating element arranged on the porous body for heating and atomizing the aerosol-forming substrate absorbed and conducted by the porous body. Among them, the porous body has a large number of micrometer-sized pores, through which the infiltration, absorption and conduction of the aerosol-forming matrix can be carried out; and the heating element is us...
