[0034] Working principle: When in use, the motor 211 is turned on. Since the output gear of the motor 211 is meshed with the gear ring 210 on the outer side of the rotating ring 208, after the motor 211 is turned on, the output gear of the motor 211 rotates to drive the rotating ring 208 to rotate, and the inner wall of the rotating ring 208 is provided with an inclined fan blade 212, so that after the fan blade 212 rotates, it drives the outside air to enter the top groove 201 from the air inlet pipe 203 and the through hole 215. After the outside air passes through the filter hole 214, the dust particles are left under the top plate 213, and the filtered air is discharged from the exhaust hole 216. After use, the dust box 205 is pulled out to clean the dust;

[0035] When the motor 211 is turned on, the cylinder 304 is turned on to control the output end of the cylinder 304 to move up and down reciprocatingly, thereby driving the push block 309 to move up and down reciprocatingly through the connecting rod 305 and the slider 306. When the top of the push block 309 moves below the connecting pipe 302, the water in the water tank 303 enters the top pipe 301 through the connecting pipe 302. Since the push block 309 moves downward, the vibration block 311 is driven to move downward until the vibration block 311 contacts the top of the top plate 213, thereby generating an impact force on the top plate 213, and then the top plate 213 vibrates, thereby the lower surface of the top plate 213 is The adhered dust is shaken off, thereby preventing the filter holes 214 on the top plate 213 from being blocked by the dust, thereby improving the filtering effect of the filter holes 214 on the top plate 213 on the dust. After the push block 309 moves back, due to the action of the anti-backflow unit 312, the water entering the top pipe 301 cannot flow back from the connecting pipe 302, so that the push block 309 pushes the water in the top pipe 301 upward to be sprayed out from the water sprinkling hole 308, and the water sprinkling hole 308 is set with a small aperture, so that the sprayed water is atomized, so that the atomized water mist combines with the dust particles in the air, which is convenient for dust reduction in the air;

[0036] When water enters the top pipe 301 from the water tank 303, the water enters the movable groove 3122 from the side groove 3123 of the movable block 3124 away from the second spring 3125, and enters the top pipe 301 through the water passing groove 3127 and the water passing main groove 3126. When the water in the top pipe 301 flows back, the movable block 3124 is pushed to move toward the side away from the second spring 3125 under the action of water pressure, so that the end of the water passing groove 3127 away from the second spring 3125 is in close contact with the inner wall of the movable groove 3122, so that the water passing groove 3127 is closed, so that water cannot flow back, thereby achieving an anti-backflow effect.
