It should be emphasized that, in the present application, the muffler 104 is disposed outside the compressor body 102, and the volume thereof is not limited by the volume of the compressor, after the medium is continuously compressed by the compressor body 102, the medium flows into the muffler 104 through the first exhaust pipe 108 via the exhaust port 1024 for muffling, and the muffled medium continues to flow into the condenser 106 through the second exhaust pipe 110 for condensation and heat absorption, so as to reduce the external temperature and achieve the effect of refrigeration.

For the muffler 104, because it is arranged outside the compressor body 102, a type with a larger size can be selected, thereby improving the noise reduction effect, in the present application, the diameter of the muffler 104 is limited, and the requirement for limiting the diameter is greater than or equal to 30mm, thereby reducing the attenuation effect of the muffler 104 on pulsation to the maximum extent, that is, the noise reduction amount is greater than 10db (a), and obtaining a better noise reduction effect.

For the muffler 104, because it is arranged outside the compressor body 102, a type with a larger size can be selected, thereby improving the noise reduction effect, in the present application, the diameter of the muffler 104 is limited, and the limitation is more than or equal to 30mm, thereby making the noise reduction amount more than 10db (a), and obtaining a better noise reduction effect.

The compressor body 102 is provided with an inner exhaust pipe 1022, and a high-pressure medium formed by the piston in the compressor body 102 through continuous reciprocating motion is discharged outwards under the action of the inner exhaust pipe 1022. Specifically, the medium will be exhausted through the exhaust port 1024 of the inner exhaust pipe 1022 to the first exhaust pipe 108 for subsequent silencing by the silencer 104.

By limiting the diameter of the first exhaust pipe 108 to be smaller than the diameter of the exhaust opening 1024, the first exhaust pipe 108 is inserted into the inner exhaust pipe 1022 to facilitate connection of the two when connected.
