Specifically, since the first filter 63 is disposed obliquely, after the first filter 63 filters the refrigerant, the refrigerant drives the impurities to move downward along the surface of the first filter 63, so that the impurities filtered by the first filter 63 enter the inner cavity of the flow guiding frame 64 through the first flow guiding hole 621, the flowing refrigerant also enters the inner cavity of the flow guiding frame 64 and drives the impurities to enter the inner cavity of the second flow guiding hole 641, the refrigerant drives the impurities to flow into the inner cavity of the connecting pipe 71 after passing through the second flow guiding hole 72, then enters the collecting box 73, and the impurities in the refrigerant remain in the inner cavity of the collecting frame 731 through the second filter 732 and flow into the inner cavity of the casing 1 again through the second filter 732.
