Compressor

Abstract

The compressor comprises an air cylinder cover and a drainage device, and a groove with an opening facing the air outlet side is formed in the air cylinder cover; an exhaust hole is formed in the bottom surface of the groove; the peripheral wall face of the groove is provided with a flow guide area, and the distance between the flow guide area and the axis of the exhaust hole is gradually increased in the direction from the air inlet side to the air outlet side of the air cylinder cover. The drainage device is arranged in the groove and provided with a flow guide face facing the exhaust hole. When the flow guide face guides flow, the distance between the position, close to the flow guide area, of the flow guide face and the bottom face of the groove is larger than that between the position, away from the flow guide area, of the flow guide face and the bottom face of the groove. The compressor is low in noise during operation, and the use experience of a user is good.
