Rotary vane electronic sucking pump with built-in porous silencers

The invention discloses a rotary vane electronic sucking pump with built-in porous silencers. The sucking pump comprises a pump body, a connecting base and a motor. The pump body comprises an upper sealing cover, the upper porous silencer, an upper cover plate, a stator, a rotor shaft, a lower cover plate, the lower porous silencer and a lower sealing cover. A rotary vane is arranged in a rotary vane groove. The rotor shaft is concentrically arranged in an oval cavity of the stator. A gap between the stator and the rotor shaft forms two sections of symmetrical pump cavities. The stator is provided with an air inlet nozzle hole, an air outlet nozzle, a through air inlet hole and a through air outlet hole. The upper cover plate and the lower cover plate are each provided with two non-throughair inlets, two through air outlets, a through air outlet hole and a semi-elliptical non-through annular groove. The upper sealing cover and the lower sealing cover are respectively provided with reactive silencing expansion
