Air energy heat pump system with non-stop defrosting mechanism

The invention discloses an air energy heat pump system with a non-stop defrosting mechanism, which relates to the field of heat pump systems and comprises an air energy heat pump outdoor unit shell and an open frame groove formed in one end face of the air energy heat pump outdoor unit shell. Two frame plates which are vertically and symmetrically distributed are fixedly installed on the side, close to the open frame groove, of the interior of the air energy heat pump outdoor unit shell, a heat transfer copper pipe which is in a bent and folded shape is fixedly arranged between the two frame plates, and a plurality of cooling fins which are linearly distributed at equal intervals are further arranged between the two frame plates. The ice and snow separating unit is driven by the driving unit to clean ice and snow between every two adjacent cooling fins, then hot air exhausted by the compressor is directly guided into the heat transfer copper pipe of the evaporator in cooperation with the four-way valve, the h
