Atomizer component, battery component and electronic cigarette

Abstract

An atomizer component, a battery component and an electronic cigarette are provided. A knurl configuration is provided, the knurl protrudes from a surface of an end cover of the atomizer component, where the end cover and an atomizer sleeve are contacted closely. A knurl configuration is provided, the knurl protrudes from a surface of an end cover of the battery component, where the end cover and a battery sleeve are contacted closely. The knurl configuration is defined on the outer surface of the circumferential side wall of the joint part of the end cover. The drawbacks in the prior art, that the end cover may easily fall apart from the sleeve resulted from the smooth surface contact there between and the glues between them may run out to be dirty and harmful when implementing the gluing process, can be overcome.
