Abstract
A device capable of automatically igniting or heating a cigarette includes a heat source system, a control system, and the openable and closeable top cover. The heat source system includes the electric heating chamber and the igniter. The igniter includes the electric heating element. The electric heating chamber includes at least one pair of light passing holes of the electric heating chamber. The control system includes the control circuit board, the mechanical switch, the mode switching switch, the infrared light source, the light sensing switch, and the device main circuit switch. The mechanical switch controls the top cover to be opened or closed and controls the device main circuit switch to be turned on or off. The mode switching switch is used for switching between an operation of the igniter and an operation of the electric heating chamber.
