The invention discloses a control method and a control device of an electronic cigarette and the electronic cigarette, and belongs to the field of electronic technologies. The method is applied to theelectronic cigarette. The method comprises the following steps: judging that whether a movement event occurs on the electronic cigarette or not, wherein the movement event is an event detected through an acceleration sensor; and when the movement event occurs on the electronic cigarette, carrying out the function corresponding to the movement event, wherein the functions at least comprise the suction control function, the standby function, the preheating function, the startup and shutdown function and the work mode control method. According to the technical scheme, the movement event is enabled to occur on the electronic cigarette as long as the user adjusts the position of the electronic cigarette, then the electronic cigarette automatically performs the function corresponding to the movement event, therefore, the operation performed when the user controls the electronic cigarette to work is greatly simplified, then the user can easily and conveniently control the work of the electronic cigarette, and finally, the control efficiency for the electronic cigarette is improved.
