Abstract

The present invention relates to a automatic shut-off device for water pup. This device comprises a main controller, a water pump operation detecting unit and a power switch connecting to the output terminal of the main controller. The power switch and the water pump operation detecting unit are serially connected to the power circuit between the alternating current and the water pump, where the water pump operation detecting unit further connects to the main controller. When the water pump runs normally, the power switch is under OFF status, on the contrary, the main controller is able to be informed through the water pump operation detecting unit and makes the power switch to be under ON status to shut off the power circuit of the water pump, so as to prevent the noise and breakdown caused by the incessant ON and OFF of the water pump motor induced by the vibration of water valve.
