[0027] In this embodiment, the front end of the air intake cylinder 1 is provided with an air intake grille 12, which is typically bolted to the air intake cylinder 1. A spray device 2 is mounted on the air intake cylinder 1, typically on both sides of the air intake cylinder 1. The rear end of the air intake cylinder 1 is fixed to the front end of the separator cylinder 3. The air intake grille 12 is uniformly distributed with small holes to prevent large impurities from entering the air intake cylinder 1, effectively preventing large impurities from entering the multifunctional air intake device.

[0028] The vane mechanism 17 in this embodiment includes an inner cylinder block 37 that prevents fluid from directly entering the inner cylinder 36 from the intake cylinder 1, and several vanes 35 for centrifuging the fluid.

The air entering from the air inlet cylinder 1 enters the air compressor main unit along the fluid channel, thereby purifying the air entering the air compressor main unit and adjusting the air intake volume.

The first moving block 32 , the second moving block 18 , the third moving block 21 and the fourth moving block 24 cooperate with each other to adjust the opening size of the air outlet 34 of the base 11 .

[0036] The drive motor 10 in this embodiment is mounted on the base 11 via a sheet metal fastener 27. The output shaft of the drive motor 10 is connected to the side gear 26, and the drive motor 10 can drive the side gear 26 to rotate. The side gear 26 meshes with the outer ring of the internal gear 29, and the rotation of the side gear 26 can drive the internal gear 29 to rotate. An internal gear 29 is provided on the circular guide groove. The internal gear 29 is capable of rotating on the circular guide groove. The internal gear 29 is internally meshed with the first pinion 30, the second pinion 19, the third pinion 22, and the fourth pinion 25.

[0037] The air intake method of the multifunctional air intake device for the compressor in this embodiment is as follows: the multifunctional air intake device is installed at the air intake port of the air compressor main unit. When the air compressor main unit is running, air containing impurities enters the air intake cylinder 1 through the air intake grille 12. The spray device 2 in the air intake cylinder 1 sprays. Under the action of the spray device 2, dust in the air is attached to the water mist. The air at this time contains water mist and small particles of impurities. After passing through the rotor vane 35, this air produces a cyclonic separation effect, and the air and water are cyclonically separated. Under the action of centrifugal force, the water and small particles of impurities are separated to the inner wall of the separation cylinder 3, flow downward along the inner wall of the separation cylinder 3, and are finally transmitted to the sewage outlet 4 under the action of the air flow. The high-humidity air after the air-water separation flows back along the outer wall of the inner cylinder 36 to the air intake channel 39 between the inner cylinder 36 and the inner cylinder block 37, then flows into the inner cylinder 36 and flows to the drying chamber box 5. After the separation of gas and water, the high-humidity air is greatly reduced in humidity by the drying plate 13 of the drying plate suitcase 14. The air dried by the drying plate suitcase 14 enters the buffer box 8 along the square tube 6. The humidity sensor 9 in the buffer box 8 is used to monitor the humidity value of the air and observe whether the humidity value of the air meets the working conditions. If the humidity value of the air does not meet the working conditions, the drying plate 13 in the drying plate suitcase 14 needs to be replaced. Finally, the opening size of the air outlet 34 of the base 11 is controlled by the air outlet opening adjustment mechanism 33 to adjust the air intake of the air compressor. The air that meets the humidity value enters the air inlet of the air compressor main unit through the air outlet 34.
