Inspection openings 25 are provided on the side positions of the air supply bin 3 and the exhaust bin 4, and an inspection door 26 is movably connected to the inspection opening 25. When the air blower 7 is started, the air blower 7 introduces external gas into the air supply bin 3, and a large amount of atomized liquid is sprayed out through the atomizing nozzle 12 to fill the entire air supply bin 3. The spiral condenser 8 on the air blower 7 allows the cooling liquid to wrap around the air blower 7, thereby reducing the heat generated when the air blower 7 is working, so that the temperature of the gas delivered from the air supply bin 3 is reduced, and the cooling effect is improved.

The exhaust bins 4 are interconnected, and a No. 2 absorbent cotton 20 is provided on the side of the connecting pipe 19. The No. 2 absorbent cotton 20 is fixedly connected to the connecting pipe 19 through a No. 2 fixing ring 21. The exhaust fan 23 is started to draw a negative pressure into the exhaust bin 4, so that the exhaust bin 4 sucks external air through the exhaust port 16. A No. 2 filter rack 18 is fixedly connected to the No. 2 wind collecting hood 17. The No. 2 filter rack 18 filters the gas to remove impurities such as dust. The atomizing nozzle 12 sprays a large amount of atomized liquid, so that the atomized liquid fills the exhaust bin 4 and mixes with the gas, thereby reducing the temperature of the gas. The gas passes through the No. 2 absorbent cotton 20, thereby absorbing the atomized liquid and drying the gas, so that the gas with reduced temperature is discharged from the exhaust port 24, thereby improving the cooling effect.

[0024] It should be noted that the present invention is an integrated air supply and exhaust device that can filter gas. When the blower 7 is started, the blower 7 sucks in the external gas and sends it into the air supply bin 3. The airflow passes through the No. 1 air collecting hood 9.

Then the valve on the atomizing water pipe 11 on the side of the No. 1 air collecting hood 9 is opened, and the atomizing nozzle 12 atomizes the liquid and sprays it out, so that the atomized liquid fills the air supply bin 3. As the air pressure in the air supply bin 3 increases, the gas passes through the No. 1 absorbent cotton 14 and enters the air supply port 13, thereby sending the gas out. After the atomized liquid mixes with the gas, the temperature of the gas is reduced. When the gas passes through the No. 1 absorbent cotton 14, the No. 1 absorbent cotton 14 absorbs the atomized liquid, thereby drying the gas. The exhaust fan 23 is started to suck the gas from the exhaust bin 4, so that a negative pressure is generated in the exhaust bin 4. The negative pressure in the exhaust bin 4 makes The external gas enters through the exhaust port 16. A No. 2 wind collecting hood 17 is provided at the lower end of the exhaust port 16. A No. 2 filter frame 18 is fixedly connected to the No. 2 wind collecting hood 17 to filter the incoming air flow, thereby intercepting impurities such as dust.

After mixing with the gas, the temperature of the gas is reduced. Then the gas passes through the No. 2 absorbent cotton 20, and the atomized liquid is absorbed by the No. 2 absorbent cotton 20, thereby drying the gas. Through this structure, a clean air flow is provided for cooling the workpiece. The two ends of the spiral condenser 8 are respectively connected to the external pipes to circulate the external cooling liquid around the blower 7 and the exhaust fan 23, thereby reducing the heat when the motor is working, and cooperating with the atomizing liquid sprayed by the atomizing nozzle 12 to reduce the temperature of the gas, so that the effect of gas cooling the workpiece is reduced.
