The low-temperature and low-pressure refrigerant enters the cylinder 1 through the air inlet pipe 2, the gaseous refrigerant, the liquid refrigerant and the frozen oil are separated in the cylinder 1, the gaseous refrigerant flows into the compressor through the air outlet pipe 3 and enters the next refrigeration cycle, and the liquid refrigerant and the frozen oil are left in the cylinder 1. The edge of the filter screen component 4 is connected with the inner wall of the cylinder body 1, and the filter screen component 4 is directly communicated with the air outlet of the air inlet pipe 2 along the air inlet direction. By the arrangement, the flow area of the filter screen assembly 4 for the refrigerant to flow through is increased, so that the flow resistance of the refrigerant is reduced, the pressure pulsation of the compressor in the periodic air suction and exhaust process can be reduced by reducing the flow resistance of the refrigerant, and meanwhile, the noise problems of a liquid separator and the compressor can be improved; and be equipped with the shielding plate on the screen frame of filter screen subassembly among the prior art, the shielding plate hinders the circulation of refrigerant for the flow area of filter screen subassembly is less, and the circulation resistance increases, and pressure pulsation and noise are all great.

In a preferred embodiment of the present embodiment, the distance between the screen assembly 4 and the intake pipe 2 is greater than the distance between the screen assembly 4 and the exhaust pipe 3. In-process that the refrigerant got into barrel 1 via intake pipe 2, because the area of the cross section of barrel 1 is greater than the area of the cross section of intake pipe 2, so the refrigerant gets into barrel 1 by intake pipe 2 after, the velocity of flow of refrigerant in barrel 1 is less than the velocity of flow in intake pipe 2, and the velocity of flow in barrel 1 can reduce gradually, set up filter screen subassembly 4 in the position that is close to blast pipe 3, also set up filter screen subassembly 4 in the less position of the velocity of flow of refrigerant, filter screen subassembly 4 itself is less to the impact force of refrigerant, just less to the circulation resistance of refrigerant. If filter screen assembly 4 sets up in the position that is close to intake pipe 2, because the velocity of flow of refrigerant in this position is great more near the velocity of flow of blast pipe 3 department, leads to filter screen assembly 4 under the great condition of refrigerant velocity of flow, filter screen assembly 4 is just great to the impact force and the hindrance effect of refrigerant. Therefore, in order to reduce the flow resistance of the screen assembly 4 to the refrigerant, the screen assembly 4 is disposed at a position where the flow rate of the refrigerant is small, that is, the screen assembly 4 is disposed at a position close to the exhaust pipe 3.
