Abstract

The invention provides a preparation method of a porous ceramic matrix, an atomizing core, an atomizer and an electronic cigarette. The atomizing core comprises the porous ceramic matrix and a heating layer; the porous ceramic matrix is a silicate porous ceramic matrix with low heat conductivity, and the heat conductivity coefficient of the porous ceramic matrix is less than 0.3 W / (m.K); the heating layer is arranged on the surface of the porous ceramic matrix. Through the arrangement, the atomizing core is free of peculiar smell in the atomization process; the porous ceramic matrix has a low heat conductivity coefficient, heat is concentrated on the atomizing surface of the atomizing core as much as possible, the atomizing temperature of the tobacco juice is reached within a short time, the taste consistency in the smoking process is guaranteed, the reduction degree of the tobacco juice is good, the taste of the smoke is improved, and meanwhile the endurance time of a battery is prolonged.

Description

technical field [0001] The invention relates to the technical field of atomizers, in particular to a method for preparing a porous ceramic substrate, an atomizing core, an atomizer, and an electronic cigarette. Background technique [0002] Electronic cigarettes are electronic products used to quit smoking or replace cigarettes. E-cigarettes produce smoke by heating and atomizing the smoke liquid, and the smoke produced has the same taste and feel as cigarettes. And when the smoke liquid is heated and atomized, it will not produce harmful components such as tar and suspended particles in the cigarette. [0003] The atomizing core in electronic cigarettes is the main component for storing and producing e-liquid, and porous ceramics are favored because of their excellent characteristics such as high porosity, good oil storage, unfavorable burnt paste, and high degree of reduction of flavor in e-cigarettes. Widely used in atomizing cores. Therefore, ceramic atomizing cores a...
