Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-5 This utility model provides an embodiment of a cleanroom air circulation and purification duct structure, including a purification duct body 7. One end of the purification duct body 7 is sealed and connected to an exhaust chamber 4 through an air inlet pipe 6. A spraying mechanism 11 and an activated carbon adsorption mechanism 12 are respectively installed inside the purification duct body 7. The activated carbon adsorption mechanism 12 and the purification duct body 7 are detachable. The spraying mechanism 11 includes a spray pipe 18, a spray head 19, and a water inlet pipe 8. The spray head 19 is evenly distributed at both ends of the spray pipe 18. The spraying mechanism 11 is used to further spray and settle the dust inside the purification duct body 7.

[0023] Furthermore, the water inlet pipe 8 and the spray pipe 18 are sealed and connected. A switch control valve 9 is installed on the water inlet pipe 8. One end of the water inlet pipe 8 is connected to a water tank through a spray pump. The water in the water tank can be transported to the spray pipe 18 through the water inlet pipe 8 by the spray pump. Finally, the water is sprayed out quickly in an atomized form through the spray head 19, thereby quickly spraying and settling dust particles.

[0024] Furthermore, the activated carbon adsorption mechanism 12 adopts an activated carbon mesh or activated carbon plate structure, which is convenient for adsorbing and removing dust particles in the air entering the purification air duct body 7 layer by layer.

[0025] Furthermore, an air extraction slot 5 is provided at the upper end of the air extraction chamber 4. An air extraction fan 13 is installed inside the air extraction chamber 4. A motor mounting box 1 is installed on one side of the exterior of the air extraction chamber 4. A transmission box 2 is installed on one side of the motor mounting box 1. A drive motor 17 is installed inside the motor mounting box 1. The output end of the drive motor 17 is connected to the drive wheel 16 located inside the transmission box 2 via a rotating shaft. A driven wheel 14 is connected to the surface of the drive wheel 16 via a belt 15. The center of the surface of the driven wheel 14 is connected to the air extraction fan 13 via a rotating shaft 3. By turning on the drive motor 17, the drive wheel 16 is driven and controlled to drive the driven wheel 14 to perform transmission, thereby driving and controlling the air extraction fan 13 to operate rapidly, which can quickly draw indoor air from the air extraction slot 5 into the purification air duct body 7.

[0026] Furthermore, an exhaust slot 10 is provided on the side surface of the purification air duct body 7 to facilitate the discharge of the purified air after the purification air duct body 7 is completed.

[0027] Working principle: During use, the drive motor 17 is turned on to drive the active wheel 16, which in turn drives the driven wheel 14, thereby driving and controlling the exhaust fan 13 to run rapidly. This allows indoor air to be quickly drawn into the purification duct body 7 from the exhaust port 5. The purification duct body 7 is equipped with a spray mechanism 11 and an activated carbon adsorption mechanism 12. The activated carbon adsorption mechanism 12 is detachable from the purification duct body 7. The spray mechanism 11 includes a spray pipe 18, a spray head 19, and a water inlet pipe 8. The activated carbon adsorption mechanism 12 is evenly distributed at both ends of the spray pipe 18. It is convenient to adsorb and remove dust particles in the air entering the main body of the purification air duct 7 layer by layer. The water in the water tank can be transported to the spray pipe 18 through the water inlet pipe 8 by the spray pump. Finally, it is quickly sprayed out in the form of atomization through the spray head 19, so as to quickly spray and settle the dust particles. The side surface of the main body of the purification air duct 7 is provided with an exhaust slot 10, which is convenient for exhausting the purified air of the main body of the purification air duct 7.
