The electromagnetic switching valve is arranged in the exhaust silencing box, so that noise generated when the electromagnetic switching valve works can be isolated from the outside, and the working noise of the electromagnetic switching valve and the exhaust noise of the electromagnetic switching valve are effectively reduced.
Because the electromagnetic switching valve is excited by pulse vibration generated by the impact of the movable iron core and the metal component of the valve body, the vibration conduction force generated by the low-order mode vibration mode of the electromagnetic switching valve is stronger, the vibration damping layer 6 is arranged between the electromagnetic switching valve and the exhaust silencing box, the vibration damping layer 6 is composite damping cotton, specifically, the composite damping cotton is made of high-density polyurethane cotton, and the vibration mechanical energy is converted into heat energy through the internal friction motion generated by the deformation stress action of the material of the vibration damping layer, so that most of vibration energy is absorbed, the low-frequency vibration during the action of the electromagnetic valve is inhibited, and the noise is reduced and is conducted to the cavity of the compressor assembly and the resonance formed by.
