In summary, referring to fig. 1 to 5, in the compressor provided in the embodiment of the present application, the mixing of refrigerant and refrigeration oil in the working chamber 7 of the compressor is reduced, the oil discharge rate is reduced, and meanwhile, the refrigeration oil flowing back to the lower cover 203 from the gap between the stator 101 and the rotor 102 of the motor 10 is also reduced, so that the resistance loss caused by oil churning is reduced. In addition, the refrigeration oil separated from the refrigerant can be guided, and flows to the oil pool of the lower cover 203 through the cutting edge of the stator 101 of the motor 10.
