Abstract

An atomizing electronic cigarette has an atomizing core component and a liquid storage component including an electric heater. The electric heater may have a through hole aligned with a channel passing through the liquid storage component. The cigarette can heat and uniformly vaporize liquid from the liquid storage component, with the user inhaling the vaporized liquid. The vapor generated by the atomizing process may be cooled as it flows through the channel.

Claims
