During normal use, the air flow passing through the heating and ventilation duct can be purified by the multiple filters 11 in the installation frame 12, so that the dust in the heating and ventilation duct can be filtered out. When a lot of dust is attached to the filter 11, the handle 3 is pulled, and then the installation frame 12 is moved downward through the slide column 14, so that the installation frame 12 is moved into the cleaning box 3, and then the air outlet end of the blower can be connected to the air inlet 6, the air inlet end of the dust collection device is connected to the exhaust port 4, the water inlet 9 is connected to the water injection pipe through a water pump, and then the air is blown into the air inlet 6 by the blower, and clean water is injected through the water inlet 9. The water is sprayed out through the water spray holes on the water spray pipe 10, and the air flow enters the distribution through the air inlet 6. The dust in the air flow box 8 is then sprayed out through the multiple air outlets 801 on the diverter box 8, and the water sprayed out from the water spray holes is brought out, thereby blowing onto the multiple filter screens 11, and the multiple filter screens 11 are backwashed. Subsequently, the air flow carries the condensed dust and is discharged into the dust collection device through the exhaust port 4, thereby cleaning the filter screen 11. After cleaning, the installation frame 12 can be moved into the air duct 1 through the adjustment mechanism; through the setting of the adjustment mechanism, the filter screen 11 in the installation frame 12 can be quickly moved into the cleaning box 3, and through the setting of the separation box and the water spray pipe 10, a uniform air flow carrying droplets can be sprayed out from the air outlet 801, so that the dust on the filter screen 11 is easier to be washed off, and the cleaning effect is better.
