Abstract
The utility model is a water-pump pressure controller comprising a body with a water inlet and a water outlet, a diaphragm in a cavity connecting with the water inlet in the body, and a pressing block and a pressing spring which press tightly on the diaphragm. A micro-switch whose button touches the pressing block is arranged on one side of the pressing block. A control circuit board whose corresponding input end connects electrically with the micro-switch. An impeller on which a magnet is set is arranged in the cavity connecting with the water inlet. A coil arranged on the corresponding position of the magnet connects electrically with the corresponding input end of the control circuit board. The control circuit processes the pressure signal which is input by the micro-switch and the flow signal which is produced by the action of the magnet on the impeller and the coil to control the work of the water-pump by controlling the water pressure and cutting off the power supply of the water-pump to protect the water-pump when the headstream is small in flow caused by water shortage.
