For the connection between the liquid storage connecting pipe 3 and the inner pipe 2 and the air inlet connecting pipe 6, a sleeving manner is generally adopted, that is, the end part of the liquid storage connecting pipe 3 is fixedly arranged in the inner pipe 2 or the air inlet connecting pipe 6 in a penetrating manner, or the liquid storage connecting pipe 3 is sleeved outside the inner pipe 2 or the air inlet connecting pipe 6, in order to ensure air tightness, the connecting pipe 3 is matched with the inner pipe 2 and the air inlet connecting pipe 6 in size, but for the compressors of different models, the inner pipe 2 is usually different in size, the air inlet hole is also different in size, and the air inlet connecting pipe matched with the air inlet hole is also different in size.

Moreover, when the difference of the fit sizes of the connecting pipe 3 and the inner pipe 2 or the air inlet hole is large, the end part of the connecting pipe 3 is simply flared, so that the wall thickness of the flaring part is too thin, the strength is poor, and the quality risks of the liquid reservoir and the compressor body in terms of welding, structural strength and the like are increased.

According to the compressor disclosed by the embodiment 1, only one part of the liquid storage connecting pipe is subjected to structural change, the inner diameter of the inner hole of the liquid storage connecting pipe is kept unchanged while the communication between the inner pipe of the liquid storage device and the compression working space in the pump body is realized, so that the flow cross section area in the liquid storage connecting pipe is unchanged, the air suction channel cross section area of the compressor body is not mutated, the problems of fluid pulsation and vortex in the air suction channel are effectively avoided, the fluid noise is reduced, the noise of the compressor is further reduced, the air suction loss caused by the mutation of the air suction channel cross section area is reduced, and the energy efficiency of the compressor is improved.
Specifically, the liquid storage connecting pipe 3 further includes a connecting section 33, and two ends of the connecting section 33 are respectively connected and communicated with the first pipe section 31 and the second pipe section 32.
In practical production, for compressors of different types, the inner tube of the liquid storage device is not necessarily completely matched with the liquid storage connecting tube 3 and the air inlet connecting tube matched with the air inlet hole of the pump body is not required to meet design requirements, and in order to ensure that the inner hole of the liquid storage connecting tube 3 has a uniform inner diameter so as to avoid the problem of noise caused by fluid pulsation and vortex, in the embodiment of the utility model, in order to change the wall thickness of the first tube section 31 and the second tube section 32, for example, for the inner tube 2 and the air inlet hole with slightly smaller inner diameter, the wall thickness of the first tube section 31 and the second tube section 32 is not greater than the wall thickness of the connecting section 33 by cutting the first tube section 31 and the second tube section 32, further, the wall thickness of the first tube section 31 and the second tube section 32 is not less than 30% of the wall thickness of the connecting section 33, and the minimum wall thickness of the first tube section 31 and the second tube section 32 is limited, so that the structural strength is ensured, and the vibration noise caused by insufficient strength is reduced.
