Atomizing core and electronic atomizing device

Abstract

The invention relates to an atomizing core and an electronic atomizing device. The atomizing core comprises an oil guide layer, a preheating layer and a heating layer which are sequentially arranged in a stacked mode, wherein the oil guide layer, the preheating layer and the heating layer are all porous structure layers with micropores, and the heating layer completely covers the other side, away from the oil guide layer, of the preheating layer. According to the atomizing core, the preheating layer is covered with the heating layer, due to the fact that the heating layer is integrally conductive, uniform heating of the whole face between the preheating layer and the heating layer can be achieved, the atomization effect is better, the atomization core has advantages of being rapid in temperature rising and high in heat efficiency, meanwhile, problems of local dry burning and burning are avoided, the heating layer is the porous structure layer with the micropores, so aerosol generated after the tobacco tar is heated and atomized can directly escape from the micropores in the heating layer, the atomization speed is higher, and the use requirement of a large-smoke-amount user can be met.

Description

technical field [0001] The invention belongs to the technical field of electronic atomization, and in particular relates to an atomization core and an electronic atomization device. Background technique [0002] The existing ceramic atomizing core copper material adopts a double-layer structure, and the etched circuit or printed thick film circuit is used as a heating element on the surface of the microporous ceramic (liquid storage layer), and the heating element is made of a metal or a metal alloy with a certain resistance value. The formed electric heating circuit (such as a heating wire or a heating net), the microporous ceramic has a relative oil-absorbing surface and a heating atomizing surface, and the heating element is located on the heating atomizing surface of the microporous ceramic. The smoke liquid on the heat-generating atomizing surface of the ceramic is heated and atomized to generate aerosol. But such a structure has the following problems: [0003] 1. Si...

AI Technical Summary

Problems solved by technology

[0003] 1. Since the heating element is an electric heating circuit formed on the surface of the microporous ceramic, it does not completely cover the heating and atomizing surface of the microporous ceramic, thus causing heat generation and atomization in different areas of the heating and atomizing surface of the microporous ceramic, and heating Uneven, prone to local overheating and core burnt

[0004] 2. The electric heating circuit is easy to fall off from the microporous ceramics during the repeated heating and cooling process

[0005] 3. When the atomization speed is fast, the e-liquid cannot be in contact with the electric heating circuit in time, resulting in dry burning of the electric heating circuit, which will cause the aerosol to produce a sticky smell, which will affect the taste of the user.
