Abstract

An electronic cigarette is provided, comprising: a battery sleeve, an outer tube, an internal threaded sleeve, an external threaded sleeve and an upper electrode; the upper electrode defining a first through hole therein, the external threaded sleeve defines a second through hole therein, the internal threaded sleeve includes a barrel and a ring step formed relative to a periphery of barrel, the ring step includes an upper end surface and a lower end surface, the upper end surface is a wave-shaped end surface, the lower end surface resists and is connected with the battery sleeve, an air admission passage is formed at a point between the upper end surface and the external threaded sleeve, and the air admission passage, the second through hole and the first through hole form an air flow loop. Thus the threaded copper component does not form sharp angles and is prevented from hurting users'"'"' bodies.
