Claims19
An electronic cigarette atomization core, comprising:
- a porous ceramic base body;
- and
- a heating body,
- wherein the porous ceramic base body comprises a liquid absorbing surface and an atomization surface;
- and
- wherein the heating body is arranged on the atomization surface, the heating body being a porous heating body, and wherein the porous heating body has a porosity less than or equal to 30%.
A preparation method for an electronic cigarette atomization core, comprising:
