Abstract

The utility model discloses an electronic cigarette body and a switch assembly of the electronic cigarette body. The electronic cigarette body comprises a bottom cover, an atomizer connector and a central assembly. The central assembly comprises a battery sleeve and a switch assembly. The switch assembly comprises a shell, a control unit, a switch component and a locking component. The position of a stopper can be changed by rotating the locking component. When the locking component is rotated until the stopper abuts against the switch component, the switch component cannot move radially inward to trigger the control unit, so that the control unit cannot open the electronic cigarette body. Since the locking component rotates relative to the shell in situ instead of being screwed with the shell, no matter what angle the electronic cigarette is placed at, the locking component will not be inclined to open due to the weight of the locking component, so that the locking component can effectively keep the switch component locked to prevent the electronic cigarette from being accidentally opened.
