Through the cooperation of the air pump 25 and the suction pipe 24, the dust suction seat 23 that moves up and down reciprocates to absorb the dust floating in the ventilation duct body 1, and at the same time, The holes arranged on the surface of the dust suction seat 23 are facing the holes on the inner bottom wall of the ventilation duct body 1, and can also absorb dust on the inner bottom wall of the ventilation duct body 1, and the dust suction seat 23 can be expanded by moving up and down to absorb the dust. The absorbed dust is then discharged into the dust collecting bag 30 through the discharge pipe 26. When a certain amount of dust is collected in the dust collecting bag 30, the connecting ring 29 can be directly rotated to remove the dust collecting bag 30 from the fixing seat 27, and then the dust collected in the dust collecting bag 30 can be cleared. The above is the working principle of the ventilation duct with a ventilation structure.
