[0018] When the utility model is in use, external air enters the compressor body 5 from the compressed air inlet 8, and cold oil enters the compressor body 5 from the compressed oil inlet 10. After the air and the cold oil pass through the compressor body 5, an oil-gas mixture is formed. The oil-gas mixture passes through the compressed air outlet 9, the mixed air pipe 19 and the mixed air inlet 14 and enters the oil-gas separator 7. The oil-gas separator 7 separates the oil-gas mixture into compressed gas and hot oil. The compressed gas passes through the separation gas outlet 15, the gas storage gas pipe 20 and the gas storage inlet 4 and enters the gas storage cylinder 1 for storage. The gas storage outlet 2 can be used to supply gas to the gas user end. The hot oil passes through the separation oil outlet 16, the first oil pipe 21 and the cooling inlet 1 7 enters the cooler 6, the hot oil is cooled by the cooler 6 to form cold oil and enters the oil-cooled motor 11 through the cooling outlet 18, the second oil pipe 22 and the cold oil inlet 12. The temperature of the cold oil will not be too low after being heated by the oil-cooled motor 11. If the oil-cooled motor 11 generates heat after working for a period of time, it can also be cooled by the cold oil. The cold oil and the oil-cooled motor 11 interact with each other to reach their respective suitable working temperatures. The cold oil with suitable temperature enters the compressor body 5 again through the cold oil outlet 13, the third oil pipe 23 and the compression oil inlet 10. Since the temperature of the cold oil is not too cold, even if the compressor body 5 is frequently started and stopped, no water accumulation will be generated, thereby ensuring the performance of the air compressor.
[0019] Preferably, a bearing oil inlet 24 is provided on the compressor body 5, and a bearing oil outlet 25 is provided on the oil-gas separator 7. The bearing oil outlet 25 is connected to the bearing oil inlet 24 through a fourth oil pipe 26, so that lubricating oil can be provided to the bearings of the compressor body 5 at any time, thereby extending the service life of the air compressor.

The oil amount in the oil-gas separator 7 can be observed through the separation level gauge 30. If the oil amount is insufficient, oil can be added to the oil-gas separator 7 through the separation refueling port 27, and dirt in the oil-gas separator 7 can be discharged through the separation drain port 28. When the pressure in the oil-gas separator 7 is too high, the separation safety valve 31 on the separation safety port 29 automatically opens to release the pressure, ensuring safe use.
