Problems solved by technology

However, due to the diversity of use places and atomizing liquids, the application fields of porous ceramic atomizers are greatly limited.
[0003] Most of the porous ceramic substrates currently on the market are amorphous solid powder ceramic powders, so that the prepared porous ceramics generally have defects such as oil storage, insufficient oil locking function, oil leakage, etc., and the porosity ratio of the porous ceramic substrate The problem of high liquid absorption rate and high porosity leads to the problem of low utilization rate of e-liquid

Abstract

The invention relates to the technical field of porous ceramics, in particular to a high-liquid-absorption-rate porous ceramic matrix and a heating element, and the high-liquid-absorption-rate porous ceramic matrix is prepared from the following raw materials in parts by weight: 25-90 parts of porous silicon dioxide microspheres, 10-30 parts of glass powder, 0.1-25 parts of diatomite, 0.1-10 parts of quartz sand and 0.1-10 parts of aluminum oxide. The porous ceramic matrix has the characteristics of small pores, high liquid absorption rate and large ratio of the liquid absorption rate to the porosity, tobacco tar permeation and atomization are facilitated, the atomization rate of the tobacco tar is increased, the smoke amount is increased, and the experience feeling of a user is improved; due to the fact that the adopted porous silicon dioxide microspheres are provided with micropores, and the micropores are small and large in number, tobacco tar can penetrate through the porous silicon dioxide microspheres more conveniently compared with an existing large-aperture porous ceramic matrix. and the heating element prepared by using the porous ceramic substrate has the characteristics of small pores, high liquid absorption rate and large ratio of the liquid absorption rate to the porosity, so that the penetration and atomization of the tobacco tar are facilitated, the atomization rate of the tobacco tar is improved, the smoke amount is increased, and the experience feeling of a user is improved.
