Air compressor unloading system

The utility model discloses an air compressor unloading system which comprises an air compressor, an electromagnetic valve, a condensation assembly and a gas treatment module. An air inlet pipeline and an exhaust pipeline are arranged on the air compressor, and the air inlet pipeline is communicated with the electromagnetic valve through an air inlet unloading pipeline; one end of the electromagnetic valve is communicated with the exhaust pipeline, and the other end of the electromagnetic valve is communicated with one end of the condensation assembly; the other end of the condensation assembly is connected with the gas treatment module. Under the condition that the air treatment module does not need the air compressor to inflate, the electromagnetic valve can be controlled to cut off the passage between the air compressor and the air treatment module and open the passage of the air inlet unloading pipeline, so that the air pumped by the air compressor is sucked into the air compressor cylinder again, a circu
