Noise reduction structure of rotor type compressor

The utility model discloses a rotor type compressor noise reduction structure which is characterized in that a plurality of layers of sound absorption layers are arranged and are a first material layer, a second material layer, a third material layer and a fourth material layer from inside to outside in sequence, and the material layers from inside to outside are attached through mucilage glue or are sequentially formed in an injection molding mode from inside to outside. The first material layer is connected with the surface of the compressor through hook-and-loop fasteners, the multiple sound absorption layers are provided with mounting holes or notches according to the structure of the compressor, and sealing openings are connected through the hook-and-loop fasteners. The multi-layer sound absorption layer and the multi-layer sound insulation layer are used for absorbing noise generated during operation of the compressor, and particularly have a remarkable effect on high-frequency noise above 1000 Hz, the
