The silent air compressor 100 provided in one embodiment of the utility model includes a housing 10, an air compressor 20, an oil separator 30, an air tank 40, an air-water separator 50, an oil mist separator 60 and an air inlet of the equipment. The air compressor 20 is arranged in the housing 10, and the air compressor 20 is interconnected with the outside air; the oil separator 30 is arranged in the housing 10 and is connected to the air compressor 20; the air tank 40 is arranged in the housing 10 and is connected to the oil separator 30; the air-water separator 50 is connected to the air tank 40; and the oil mist separator 60 is interconnected with the air-water separator 50.

[0035] In this embodiment, outside air can enter the silent air compressor 100 through the air compressor 20. At this time, the air compressor 20 can introduce outside air into the oil separator 30 and separate the oil in the air compressor 100 through the oil separator 30. The subsequent gas can enter the gas tank 40 for storage. When other equipment needs to use the gas source, the gas in the gas tank 40 is separated from the water in the gas through the gas-water separator 50, and then the oil mist in the gas is separated through the oil mist separator 60, and the gas is passed through the air inlet of the equipment to enter other equipment for use. Through such a setting, the noise can be reduced to a certain extent, and the oil separator 30 is used to separate the oil in the high-pressure gas, the gas-water separator can effectively filter the water in the gas, the oil mist separator 60 can filter the oil mist particles in the gas, and deliver the cleaner air to the equipment. The oil return port of the oil separator 30 can deliver the filtered oil back to the compressor through the oil return pipe 32. Extend the service life of the compressor. The gas-water separator 50 can separate the water vapor by centrifugal force, which can basically achieve maintenance-free.

[0036] In some embodiments, the oil separator 30 includes a first bellows 31 and an oil return pipe 32. The oil separator 30 is connected to the air tank 40 through the first bellows 31 and is connected to the air compressor 20 through the oil return pipe 32. The first bellows 31 and the oil return pipe 32 can absorb and reduce the pressure fluctuation of the compressed air during the flow process, thereby reducing the noise generated when the air compressor is running. The oil separator 30 is connected to the air tank 40 through the first bellows 31, so that the compressed air can be separated from the oil and gas before entering the air tank 40. The oil return pipe 32 is used to separate the lubricating oil in the oil separator 30 after passing through the oil separator 30 due to its different density and viscosity. Then the separated lubricating oil will flow back to the lubricating oil tank through the oil return pipe 32. After a certain pressure is generated in the lubricating oil tank, it will flow back to the lubrication system of the compressor through the oil return valve to maintain the normal operation of the lubrication system and ensure the long-term stability of the machine. The function of the air tank 40 is to store compressed air and stabilize pressure fluctuations. The use of the first bellows 31 can alleviate pressure fluctuations and ensure stable operation of the air compressor 20 .

[0037] In some embodiments, the air compressor 20 includes a second bellows 21 , which is connected to the oil separator 30 , and the air compressor 20 delivers air into the oil separator 30 through the second bellows 21 .

[0038] After being discharged from the air compressor 20, the compressed air enters the second bellows 21. The second bellows 21 sends the compressed air to the oil separator 30, where the oil mist in the compressed air is separated and flows back to the air compressor 20 through the oil return pipe 32, thus realizing the recycling of the oil. The dry compressed air after the oil and gas separation enters the air storage tank 40 through the pipeline and is stored for subsequent use. When the compressed air is needed, the compressed air in the air storage tank 40 is released through the pipeline for use by the equipment.

[0039] In some embodiments, the air compressor 20 further includes a first cooling fan 22, which is disposed on the outside of the air compressor 20. When the air compressor 20 is running, the first cooling fan 22 starts to work, sucking the outside air into the air compressor 20 to dissipate heat for the air compressor 20. The inhaled air passes through the heat sink of the air compressor 20, exchanges heat with the high-temperature components inside the air compressor 20, and takes away the heat. The air after the heat is dissipated is discharged from the other side of the air compressor 20, thereby reducing the temperature of the air compressor 20 and ensuring the normal operation of the air compressor 20. Through such a setting, the first cooling fan 22 can help the air compressor 20 dissipate heat, improve the working efficiency and reliability of the air compressor 20, and extend the service life of the air compressor 20.

[0040] In some embodiments, a pressure gauge 41 and a pressure switch 42 are provided on the gas storage tank 40 . The pressure gauge 41 is used to detect the air pressure value in the gas storage tank 40 ; the pressure switch 42 is electrically connected to the pressure gauge 41 and the air compressor 20 .

[0041] The pressure gauge 41 is used to detect the air pressure value in the gas tank 40 and convert it into a corresponding pressure signal. The pressure switch 42 is electrically connected to the pressure gauge 41 and the air compressor 20. When the air pressure in the gas tank 40 reaches the upper limit set by the pressure switch 42, the pressure switch 42 will receive a signal and issue a command to stop the air compressor 20 to avoid excessive pressure in the gas tank 40. When the air pressure in the gas tank 40 drops to the lower limit set by the pressure switch 42, the pressure switch 42 will receive a signal again and issue a command to restart the air compressor 20 to ensure that there is enough compressed air in the gas tank 40. Through such a setting, the air pressure in the gas tank 40 can be automatically controlled to ensure the stable operation of the air compressor 20, and protection can be performed when necessary to prevent the air pressure from being too high or too low.

[0042] Specifically, there is a spring connection inside the pressure switch 42. When the pressure is less than 0.8Mpa, the spring closes the circuit and turns on the power, and the silent air compressor 100 works. When the pressure in the air tank 40 reaches 0.8Mpa, the spring inside the switch is disconnected under the action of pressure, and the silent air compressor 100 stops working.

[0043] In some embodiments, the gas storage tank 40 further includes a third bellows 43, and the gas storage tank 40 is connected to the gas-water separator 50 through the third bellows 43. The gas storage tank 40 can introduce gas into the gas-water separator 50 through the third bellows 43.

[0044] In some embodiments, a ball valve 44 is disposed on the third bellows 43. The ball valve 44 is disposed on the third bellows 43, and the ball valve 44 can control the on / off and flow rate of the compressed air.

[0045] In some embodiments, a check valve 45 is further provided in the gas storage tank 40, and the check valve 45 is used to prevent the gas from rushing back to the air compressor 20. There is a silicone plug inside the check valve 45, and when the gas reaches a certain pressure, the rubber plug is pushed open to allow air to pass into the gas storage tank 40, and the reverse airflow will push the rubber plug, preventing the airflow from passing, thereby preventing the gas from rushing back to the air compressor 20.

[0046] It should be particularly noted that the silent air compressor 100 provided in the embodiment of the utility model only shows the part related to the technical problem to be solved by the embodiment of the utility model. It can be understood that the silent air compressor 100 provided in the embodiment of the utility model also includes other structures for realizing the functions of the silent air compressor 100, which will not be described one by one again.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Under the idea of ​​the present invention, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other changes in different aspects of the present invention as above, which are not provided in detail for the sake of simplicity.
