Porous ceramic atomizing core and preparation method thereof

Abstract

The invention provides a preparation method of a porous ceramic atomizing core. The preparation method comprises the following steps: porous ceramic for preparing the atomizing core is provided; and the porous ceramic is soaked in a solution, the soaked porous ceramic is taken out and placed in water vapor to be subjected to an in-situ hydrolysis reaction, the porous ceramic subjected to the in-situ hydrolysis reaction is sintered, and the porous ceramic atomization core with the surface covered with a nano particle layer is obtained, wherein the solution is prepared by dissolving a first substance in an organic solvent, and the first substance comprises at least one of organic silicon, trimethyl aluminum or diethyl zinc, and the nano particle layer comprises at least one of SiO2, Al2O3 or ZnO. The invention also provides the porous ceramic atomizing core prepared by the preparation method. The porous ceramic atomizing core provided by the invention is simple in structure, the preparation method of the porous ceramic atomizing core is very simple, effective penetration of tobacco tar can be realized without additionally arranging a pneumatic structure, the atomizing amount of the electronic cigarette is increased, and the user experience feeling is better.

Description

technical field [0001] The invention belongs to the technical field of porous ceramics, in particular to a porous ceramic atomizing core and a preparation method thereof. Background technique [0002] In the existing porous ceramic atomizing core, the e-liquid in the oil storage tank impregnates to the atomizing surface through the ceramic pores under the action of the pressure difference, and the formation of the pressure difference requires setting a pneumatic structure on the atomizing core to communicate with the external environment , and the pressure difference must be kept stable to ensure the continuous and stable impregnation of the e-liquid. On the one hand, this structure increases the difficulty in the preparation of the atomizing core. It is inevitable that there will be relatively large fluctuations in the pressure difference, so that the e-liquid cannot be stably infiltrated into the atomizing surface, and cannot provide enough e-liquid to the atomizing surfac...

On the one hand, this structure increases the difficulty in the preparation of the atomizing core. It is inevitable that there will be relatively large fluctuations in the pressure difference, so that the e-liquid cannot be stably infiltrated into the atomizing surface, and cannot provide enough e-liquid to the atomizing surface in time, resulting in a small amount of e-cigarette atomization and poor user experience.
