The controller for intermittent operation of the exhaust fan comprises a 220V alternating current power source, an alternating current voltage reduction circuit, a full-bridge rectifier circuit, a 12V direct current voltage stabilization and filter circuit, a square wave circuit, a duty ratio regulation circuit and a photosensitive bidirectional-switch controlled circuit. The controller with the exhaust fan operating intermittently is characterized in that the model NE555 is selected as a time-base circuit IC1 in the square wave circuit and the duty ratio regulation circuit and the model MOC3061 is selected as a photoelectric coupler G1 in the photosensitive bidirectional-switch controlled circuit. In practical usage and on some occasions, firstly the exhaust fan needs to be capable of operating intermittently, and secondly the exhaust fan needs to be capable of operating for a long term and be free from burnout. According to the controller for intermittent operation of the exhaust fan, by means of the high level output by the square wave circuit formed by connecting the time-base circuit, a bidirectional-switch in the photoelectric coupler G1 is controlled to be turned on and turned off, so that the exhaust fan can be capable of operating intermittently. By regulating the output width of the square wave, the operating time and out-of-operation time of the exhaust fan can be changed.
