The exhaust hood 130 is disposed in the exhaust cavity 116, as shown in fig. 2 to 4, the exhaust hood 130 includes a partition hood 131 and a flow guiding portion 132, the partition hood 131 is disposed between the air outlet 121 and the exhaust port to partition the air outlet 121 and the exhaust port, a flow guiding cavity 13111 is disposed on one side of the partition hood 131 close to the air outlet 121, the flow guiding portion 132 is disposed on the partition hood 131 and extends from the partition hood 131 into the first flow channel 118, a second flow channel 1321 is disposed inside the flow guiding portion 132, and the flow guiding cavity 13111 is communicated with the first flow channel 118 through the second flow channel 1321.

Specifically, the exhaust hood 130 may be assembled with the compression mechanism 120, may be assembled with the first end cap 112, and may be assembled with both the compression mechanism 120 and the first end cap 112.

Specifically, besides the first flow passage 118, various gaps exist between the inner peripheral wall of the casing 110 and the compression mechanism 120, so that the oil-gas mixture subjected to the oil-gas separation process can enter the exhaust cavity 116 through the gaps.

Referring to fig. 1, the straight arrows in fig. 1 indicate the flow direction of the oil-gas mixture. Firstly, the oil-gas mixture is discharged into the drainage cavity 13111 of the shield 131 from the gas outlet 121 of the compression mechanism 120, at least most of the oil-gas mixture enters the second flow passage 1321 of the drainage portion 132 under the drainage action of the drainage cavity 13111, then enters the oil-gas separation cavity 117 after sequentially passing through the second flow passage 1321 and the first flow passage 118, the oil-gas mixture continues to flow towards the second end 115 until the oil-gas mixture reaches the second end 115, the oil-gas mixture flows towards the first end 114 after being blocked by the second end 115, then various gaps between the inner peripheral wall of the casing 110 and the compression mechanism 120 enter the gas discharge cavity 116, and finally the oil-gas mixture is discharged outwards through the gas discharge pipe 180.

Therefore, under the drainage action of the exhaust hood 130, at least most of the oil-gas mixture can be subjected to effective oil-gas separation treatment, so that the oil circulation rate of the compressor 100 can be effectively reduced, and the working performance of the compressor 100 is improved.

In one embodiment, as shown in fig. 2 to 4, the partition 131 includes a cover 1311 and a flange 1312, the drainage chamber 13111 is disposed on a side of the cover 1311 away from the exhaust port, the flange 1312 is annularly disposed on the cover 1311, and an end surface of the flange 1312 is attached to an end surface of the compression mechanism 120, so that the oil-gas mixture discharged from the air outlet 121 of the compression mechanism 120 cannot directly enter the exhaust chamber 116 through an edge of the partition 131, but enters the second flow passage 1321 of the drainage portion 132 only under the drainage effect of the drainage chamber 13111, and then enters the oil-gas separation chamber 117 after sequentially passing through the second flow passage 1321 and the first flow passage 118 for oil-gas separation treatment, in other words, almost all the oil-gas mixture discharged from the air outlet 121 of the compression mechanism 120 is subjected to the oil-gas separation treatment first, then enters the exhaust chamber 116 and is discharged outside through the exhaust pipe 180, so as to further reduce the oil circulation rate of the compressor 100, so that the operation performance of the compressor 100 can be more effectively improved.

Specifically, the compressor 100 further includes a plurality of fasteners (not shown), such as bolts and screws, a plurality of first connecting holes (not shown) are formed on the flange 1312, a plurality of second connecting holes (not shown) are formed on a side of the compression mechanism 120 close to the exhaust port, each of the first connecting holes corresponds to each of the second connecting holes, and each of the fasteners passes through the corresponding first connecting hole and then is connected to the corresponding second connecting hole, so as to connect the flange 1312 and the compression mechanism 120.

Optionally, the compressor 100 further includes a sealing member (not shown) disposed between the end surface of the flange 1312 and the end surface of the compression mechanism 120, so as to further improve the sealing effect between the flange 1312 and the compression mechanism 120, and thus effectively prevent the oil-gas mixture from leaking to the exhaust cavity 116 through the joint between the flange 1312 and the compression mechanism 120, so as to ensure that the entire oil-gas mixture discharged from the gas outlet 121 of the compression mechanism 120 can be subjected to the oil-gas separation process.

In a specific example of the above embodiment, the drainage portion 132 is disposed outside the cover 1311, the flange 1312 is opened with a transition port (not shown), and the drainage portion 132 extends from the cover 1311 to the first flow channel 118 through the transition port.

In another specific example of the above embodiment, the drainage portion 132 is disposed outside the flange 1312, the flange 1312 is opened with a communication port (not shown), and the drainage chamber 13111 communicates with the second flow passage 1321 through the communication port.

In one embodiment, the number of the drainage portions 132 is multiple, and it can be understood that a plurality of first flow passages 118 are formed between the inner circumferential wall of the casing 110 and the compression mechanism 120, so that the oil-gas mixture in the drainage chamber 13111 can be quickly introduced into the oil-gas separation chamber 117, thereby effectively improving the exhaust efficiency of the compressor 100.

In the above embodiment, the number of the induction portions 132 may be determined according to the actual discharge amount of the compressor 100, and the plurality of induction portions 132 are uniformly distributed along the circumference of the shroud 131 to enable the oil-gas mixture to be uniformly discharged into the oil-gas separation chamber 117. For example, as shown in fig. 2 and fig. 3, the number of the drainage portions 132 is two, and the two drainage portions 132 are symmetrically distributed on two opposite sides of the partition cover 131; for another example, the number of the drainage portions 132 is four, and the four drainage portions 132 are distributed in an orthogonal structure.

In one embodiment, the outside of the drain 132 is sealingly connected with the port edge of the first flow channel 118. Because the oil-gas mixture is likely to collide with the inner wall surface of the casing 110 or other components when entering the first flow passage 118 or entering the oil-gas separation chamber 117 through the first flow passage 118 to generate flocculation, a part of the oil-gas mixture flows back, and by hermetically connecting the drainage portion 132 to the port of the first flow passage 118, the returned oil-gas mixture can be effectively blocked, so that the part of the oil-gas mixture is prevented from directly entering the exhaust chamber 116 and being exhausted outside through the exhaust pipe 180.

In a specific example of the above embodiment, a sealing ring (not shown) is sleeved on the drainage part 132, and the sealing ring abuts between the outer side of the drainage part 132 and the port edge of the first flow channel 118 to seal a gap between the drainage part 132 and the port edge of the first flow channel 118.

In another specific example of the above embodiment, the outside of the drain 132 is welded to the port edge of the first flow passage 118 to seal the gap between the drain 132 and the port edge of the first flow passage 118.

In one embodiment, referring to fig. 4, in order to rapidly introduce the mixture of oil and gas in the drainage chamber 13111 into the second flow passage 1321 of the drainage portion 132, the chamber wall of the drainage chamber 13111 is a curved surface, which is understood to be a convex curved surface protruding from the compression mechanism 120 toward the first end cap 112.

In another embodiment, please refer to fig. 5, in order to rapidly introduce the oil-gas mixture in the drainage chamber 13111 into the second flow passage 1321 of the drainage portion 132, the chamber wall surface of the drainage chamber 13111 is a conical surface, in other words, the longitudinal section of the drainage chamber 13111 is a triangular structure, and the vertex of the triangular structure is located near the first end cap 112.
