Abstract
An electronic control water flow switch is used for controlling starting/stopping of a water pump and comprises a valve body, a water inlet connector and a water outlet connector. The water inlet connector and the water outlet connector are connected at two ends of the valve body respectively. A spindle and an impeller are arranged inside the valve body. The spindle is perpendicular to the axis of the valve body, and the impeller is coaxially fixed on the spindle. A permanent magnet is further fixed at the bottom of the spindle, an induction coil is arranged below the permanent magnet, and a current sensor is connected with the induction coil in circuit mode. The current sensor converts generated induction current into electric signals and then transmits the electric signals to a controller for controlling the starting/stopping of the water pump. A current induction module is printed on the current sensor, and a control circuit is printed on the controller. The control circuit comprises a main control module, a voltage management module and a water pump switch module. The voltage management module reduces high voltage to low voltage applied to the main control module, and the water pump switch module is in control connection with the output end of the main control module. The impeller is arranged inside the valve body to induct water flow, thereby being sensitive in reaction. The water pump is controlled in a mode that weak current controls strong current, thereby being high in safety.
