Abstract

An electronic cigarette, including a cigarette holder assembly, an atomization assembly, a glass container for accommodating smoke oil, and a gas flow regulator. The cigarette holder assembly includes a mouthpiece, a first sealing ring, a seat for supporting the mouthpiece, a fixed screw, and a pole. The atomization assembly includes a pair of heating wires, a glass casing, a second sealing ring, a third sealing ring, oil-guiding cotton, a limit cover, an insulating ring, and a fixed ring. The glass container includes a first sealing gasket and a second sealing gasket which are respectively disposed at both ends of the glass container. The gas flow regulator includes a control ring, a steel ball, a spring, and a rotary button. The first sealing ring of the cigarette holder assembly is sleeved on the mouthpiece, and the mouthpiece is fixed on the seat via the fixed screw.
