Electronic automatic self-priming vortex pump

The utility model discloses an electronic automatic self-priming vortex pump. The problem of dry rotation of the pump of the existing common vortex pump when liquid supply of a liquid source area is not enough or an impeller is deadly locked is solved. The adopted technical measures are that the electronic automatic self-priming vortex pump comprises a pump body; a motor and the impeller are arranged inside the pump body; the impeller is arranged inside a liquid inlet cavity inside the pump body; and a pressure switch communicated with a liquid inlet cavity is arranged on the pump body. The electronic automatic self-priming vortex pump is characterized in that a flow sensor and an electronic control box are respectively arranged on the pump body; the flow sensor is used for sensing liquid flow inside the liquid inlet cavity; a circuit board with a single chip is arranged inside the electronic control box; the flow sensor and the pressure switch are respectively connected with the circuit board by virtue of le
