Abstract

An electronic cigarette includes a battery assembly, an atomizer assembly and a cigarette bottle assembly. An external thread electrode is located in one end of battery assembly. An internal thread electrode is located in one end of atomizer assembly. The battery assembly and the atomizer assembly are connected by the screwthread electrode. The cigarette bottle assembly is inserted into the other end of the atomizer assembly and both form a cigarette type or cigar type body.

First claim
