[0040] In the production process, the air compressor is powered on to start working, starts to inhale air to produce compressed gas, the fan starts to run, and the high temperature generated by the main machine is continuously taken away from the air compressor cavity by air cooling. The compressed gas generated by the main machine is transmitted to the copper pipe of the cooler through the gas distribution bag 8, and the gas is routed through the area cooled by the condenser fan.

In addition, the safety hazard investigation is more rigorous than competitors, and the pressure sensor and temperature sensor are detected at any time to ensure the safety of the user's person and property
[0042] Under the existing premise, the technical solution first designs the appearance, such as Figure 1 As shown by the frame type body 1, this shell not only looks beautiful, but also integrates the components of the air compressor in a space to form a soundproof cover effect, further containing the noise inside the cavity. In addition, the only muffler on the main machine cannot reduce more noise, and two additional mufflers 21 are added at the bottom of the device according to the main noise generating position to ensure that the noise is reduced to the minimum.

Figure 3 The electromagnetic unloading valve 7 is connected with the main machine 6, and when the compressed air generated by the continuous work of the main machine fills the gas storage tank 16, the pressure switch will first release an electric signal to stop the work of the main machine, and the electromagnetic unloading valve will receive the signal released by the pressure sensor 19 to unload, so as to avoid damage to the main machine and the air compressor, and to improve the service life of the air compressor.
