Abstract

The invention relates to a porous ceramic material, a porous ceramic and a preparation method as well as application thereof in electronic cigarette. The porous ceramic includes several superposed ceramic layers, each of which has pores, the porous ceramic includes a bottom layer and a top layer, and the pore size of the porous ceramic's pores increases layer by layer from the bottom layer to thetop layer. The porous ceramic can be applied to the atomization core of electronic cigarette, wherein the bottom layer can control the oil absorption amount, and avoids the problems of low atomizationrate and small smoke amount caused by excessive oil absorption at a time. A heating element can be printed on the top layer, the electronic cigarette liquid flows to the top layer, because of the increase of the pore size, the contact surface of the electronic cigarette liquid and the heating element is enlarged, the cigarette liquid atomization rate is increased, and then the smoke volume is increased. Layer-by-layer increase of the pores' pore size can bring smooth guidance of cigarette liquid, reduces the problem of uneven atomization or damage caused by obstructed guidance of cigarette liquid, and enhances the user's experience. The porous ceramic can also be applied to products needing pores to control substance flux.

Description

technical field [0001] The invention relates to the technical field of ceramic materials, ceramic products and preparation techniques, in particular to porous ceramic materials, porous ceramics and preparation methods thereof. Background technique [0002] E-cigarette is an electronic product that imitates cigarettes. It has the same appearance, smoke, taste and feeling as cigarettes. It is a product that turns e-liquid into steam by means of atomization and other means, and allows users to smoke. [0003] The vaporizer core of the electronic cigarette is the core component of the electronic cigarette, which determines the size and taste of the smoke produced by the electronic cigarette. Because the smoke produced by the atomizing core made of porous ceramics has no peculiar smell, most of the atomizing cores for electronic cigarettes on the market use porous ceramic atomizing cores. However, the current distribution of pores in porous ceramics is not good, and the amount o...
