Specifically, filtration 5 is the filter screen, and filter screen welded fastening is on exit tube 4 to cover intercommunicating pore 43, thereby, need not additionally to set up the structure that is used for fixed filter screen, simplify the inner structure of reservoir 100, increase the effective storage space in the reservoir 100, effectively reduce structural cost. Of course, in other embodiments, the specific structure of the filtering structure 5 is not limited to the above-mentioned filtering net, and may be other filtering components, etc.
Further, as shown in fig. 2, the inlet pipe 3 comprises a first branch pipe 31 and a second branch pipe 32, the diameter of the first branch pipe 31 is larger than that of the second branch pipe 32, the first branch pipe is conveniently and quickly inserted into the shell, the filtering structure 5 is assembled at one end of the second branch pipe 32, the other end of the second branch pipe 32 is hermetically connected with the first branch pipe 31 and is mutually communicated, so that the inlet pipe 3 is conveniently assembled, and the processing efficiency is improved.
Further, referring to fig. 2, an oil return hole 44 is formed on the outlet pipe 4 located in the cylinder 11, and the oil return hole 44 is disposed near the second end 1b of the housing 1. During the operation of the compressor, a small amount of lubricating oil is carried in the refrigerant, and after entering the reservoir 100, the lubricating oil is accumulated at one end of the reservoir 100 far away from the inlet pipe 3 and then circularly flows into the compressor pump body through the oil return hole 44, so that the lubricating oil can be prevented from being accumulated in the reservoir 100. The accumulated lubricant is usually glazed higher than the location of the oil return hole 44, and the gravity of the lubricant is higher than that of the liquid refrigerator, so that liquid refrigerant cannot enter the compressor through the oil return hole 44. And the impurities (typically, metal swarf) entering the reservoir 100 are deposited at the bottom of the second end 1b of the reservoir 100, and the oil return hole 44 is spaced from the second end 1b of the cover 12, so that the deposited impurities cannot block the oil return hole 44.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
