Atomization core, atomizer comprising same, and electronic cigarette

Abstract

This application relates to an atomization core and an atomizer including same and an electronic cigarette. The atomization core includes a porous ceramic substrate and a heating layer arranged on the porous ceramic substrate, wherein the permeation rate of the porous ceramic substrate is in a range of 0.8 mg/s.bar.mm2 to 4.0 mg/s.bar.mm2. In this application, problems of dry heating and oil leakage of the atomization core are resolved by using the porous ceramic substrate with a proper permeation rate. Through the electronic cigarette in this application, a relatively large smoke generation rate and a relatively large smoke amount can be realized, thereby improving an inhalation experience for users.
