The invention discloses a structure capable of air suction and sound reduction for a connecting rod of a compressor. The structure comprises a compressor shell and a piston device arranged in the compressor shell; the lower part of the piston device is provided with a connecting rod; the upper part of the piston device is provided with a piston; the piston comprises an annular ring and an annular ring press plate; the top part of the annular ring press plate is provided with a valve sheet; the structure is characterized in that: the compressor shell is provided with an air inlet accommodating cavity; the connecting rod is provided with an air inlet channel and a small air inlet hole; a labyrinth air inlet cavity is arranged in the piston; the small air inlet hole, the air inlet channel and the labyrinth air inlet cavity are mutually communicated; and more than two air inlet holes used for controlling the opening and the closing of the valve sheet are arranged in the annular ring press plate. By the structure, the air inlet noise of the compressor is greatly reduced, so that the comprehensive noise of the compressor is reduced. Moreover, the structure is convenient to assemble and has favorable promotion values.
Description
technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor inlet noise reduction structure. Background technique [0002] The traditional compressor air intake system is on the cylinder head, which directly enters the compression chamber through the air intake cavity of the cylinder head and the intake valve plate of the valve plate, so it is difficult to realize the overall noise reduction function of the compressor. For this reason, many noise-absorbing structures designed for compressor noise problems have also been proposed in patent documents, such as patent application number CN200710061273.7, and the name of the invention is a noise-absorbing device for a compressor. The compressor includes an electronic part and a mechanical compression part. The electronic part and the mechanical compression part are arranged in the closed cavity of the compressor shell, and the electronic part is composed of a stator and a roto...
