Abstract

An exemplary electronic cigarette includes an atomizer and a power supply. The atomizer includes one of a first connector and a second connector, and the power supply includes the other of a first connector and a second connector. The first connector includes a cylindrical plug. The plug has a recessed portion in a side surface thereof. The second connector includes a holder, a movable component, and a force exerting component. The holder is configured for receiving the plug. The movable component is movable arranged on a sidewall of the holder. The force exerting component is configured for exerting an elastic force on the movable component. The movable component is configured for ejecting from the sidewall to engage in the recessed portion when the movable component ejecting from the sidewall, and for retracting relative to the sidewall when the plug is inserted into the holder.
