Description

FIELD OF THE INVENTION

The present invention relates to a direct-feeding liquid-passing heat-generating atomization device, an atomization assembly, and an electronic atomization apparatus.

DESCRIPTION OF THE RELATED ART

Arranging a gas channel on a lateral side of a ceramic makes a side-feeding ceramic. A portion of the side-feeding ceramic that is arranged to abut an internal wall of a central tube functions to conduct a liquid, such as Patent Application No. 2022109812767. The liquid-conducting projection that is set to abut the internal wall of the central tube is provided with a liquid path zone, and the liquid path zone functions to conduct the liquid. In other words, the ceramic is allowed to directly carry out linear liquid conduction. Although, under this condition, the ceramic can speed up the transfer rate of the atomizable liquid, the transfer of the atomizable liquid on the ceramic still takes time. For a demand of a relatively high amount of generation of aerosol, meaning a large power atomization structure, the liquid-conducting projection still suffers issues of core burning resulting from insufficiency of liquid supplied through conduction, leading to a poor effect of atomization.
