The invention provides a control method of an electronic cigarette. The electronic cigarette comprises an atomization device and a battery device, wherein the atomization device comprises a liquid guide element and a heating element; the battery device comprises a wetting detection module, a control module, a storage module, a switch module and a power source module. The control method comprises the following steps: the wetting detection module detects a relevant physical quantity X and feeds back the relevant physical quantity X to the control module; the control module calculates according to corresponding relation data of relevant physical quantity X and wetting degree Q prestored in the storage module, so as to obtain the wetting degree Q; the control module judges the size relation of the wetting degree Q and a first threshold Q1; if Q is greater than or equal to Q1, the electronic cigarette operates continuously, and if Q is less than Q1, the control module sends a standby command to the switch module; the switch module disconnects the electronic connection between the power source module and the heating element. The invention further provides the electronic cigarette for applying the control method.
