An electronic cigarette includes: an atomizing assembly adapted to atomize liquid, a battery rod assembly adapted to supply power to the atomizing assembly, and a liquid storage device adapted to store the liquid a first screw section and a second screw section are respectively provided at two ends of the atomizing assembly, and a turning direction of the first screw section is opposite to a turning direction of the second screw section. The turning direction of the first screw section is opposite to that of the second screw section. Thus, when the electronic cigarette is under an external screwing force in a certain direction, either the battery rod assembly or the liquid storage device may be unscrewed and taken out, which effectively avoid a mis-operation.
