结合参见图6所示,根据本公开的实施例,一种压缩机,包括上述任一种的消音器结构实施例。With reference to Fig. 6, according to an embodiment of the present disclosure, a compressor includes any of the foregoing muffler structural embodiments.
在一些实施例中,压缩机还包括压缩机外壳1和气缸3,压缩机外壳1上设置有第一排气口2;气缸3设置于压缩机外壳1内,且气缸3上设置有第二排气口2;消音器结构设置于压缩机外壳1内;当消音器壳体4上开设有进口5和出口6时,进口5连通第二排气口2,出口6连通第一排气口2,排气过程的及时油气分离回油。在一些实施例中,出管7的第二端连通第一排气口2。In some embodiments, the compressor further includes a compressor housing 1 and a cylinder 3.

Timely oil and gas separation and oil return in the exhaust process. In some embodiments, the second end of the outlet pipe 7 communicates with the first exhaust port 2.
当压缩机长时间运行或排气带油量较大,在第一腔室的底部的集油区很可能会积存较多润滑油,如不解决,可能带来排气带油量大导致传热恶化、压缩机性能降低及回油不及时等一系列的相关问题。因此设置回油件8进行排油,在压缩机实际运行过程中,由于密封部81和限位部82都采用轻质材料,其密度小体积偏大,而密封部81在第一腔室内,由于排气压力是腔外吸气压力的数十倍,即消音腔内压力大于消音腔外压力;且回油件8在自身重力作用下实现了高要求的密封性。When the compressor runs for a long time or the exhaust oil has a large amount of oil, it is likely that a lot of lubricating oil will accumulate in the oil collection area at the bottom of the first chamber. A series of related problems such as thermal deterioration, reduced compressor performance and delayed oil return. Therefore, the oil return member 8 is provided to discharge oil. In the actual operation of the compressor, since the sealing part 81 and the limiting part 82 are made of light materials, their density is small and the volume is too large, and the sealing part 81 is in the first chamber. Since the exhaust pressure is dozens of times the suction pressure outside the cavity, that is, the pressure in the muffler cavity is greater than the pressure outside the muffler cavity; and the oil return member 8 achieves high-requirement sealing performance under the action of its own gravity.
当压缩机在暂时停机时,由于排气回油消音腔体内外压力相等,积存在第一腔室的底部有大量润滑油时,轻质且体积偏大的密封部81可实现克服自身重力,使得密封部81打开回油孔,实现了消音腔内的润滑油及时回油,限位部82起到回升时的缓冲作用。当润滑油回流后,密封部81受到的浮力和自身重力的平衡打破,又重新实现了密封。When the compressor is temporarily stopped, because the internal and external pressures of the exhaust and oil return muffler chamber are equal, and there is a large amount of lubricating oil accumulated in the bottom of the first chamber, the light and large sealing portion 81 can overcome its own gravity. The sealing portion 81 opens the oil return hole, realizing the timely return of the lubricating oil in the muffler cavity, and the limiting portion 82 plays a role of buffering during the recovery. When the lubricating oil returns, the balance between the buoyancy of the sealing portion 81 and its own gravity is broken, and the sealing is realized again.
