Then the strip plate 6 will drive the rotating plate 7 to rotate, thereby driving the rotating shaft 8 to rotate, and then driving the exhaust plate 9 to rotate, so that the exhaust plate 9 is offset to allow the gas to pass through, and then the air pressure inside the exhaust box 1 will push the sealing plate 14 to slide, and then the sealing plate 14 will push the protective plate 13 to slide, so that the sealing plate 14 can slide away from the exhaust box 1 , and then the gas is discharged.

[0036] During the gas discharge process, the filter plate 28 will capture and isolate tiny particles and pollutants that may enter the cabin through the exhaust box 1. At the same time, the rotating shaft 4 will also drive the rotating shaft 4 to rotate, thereby driving the belt 21 to rotate, and then driving the driven wheel 24 to rotate. The driven shaft 25 is driven by the driven wheel 24 to rotate, thereby driving the bottom plate 26 to rotate, and then the force-bearing plate 29 is rotated and hit. Then the force-bearing plate 29 transmits the vibration force to the filter plate 28, so that the dust adsorbed inside the filter plate 28 can fall off, so that it can continue to filter, and then improve the filtering effect.
