Until the sealing plate 6 is reset to the initial state, the controller shuts down the second electric push rod 7, and starts the first electric rotating shaft 15, the second electric rotating shaft 18 and the electromagnetic valve in the first connecting pipe 21 at the front side, the first electric rotating shaft 15 at the front side rotates and drives the collecting frame 17 to reciprocate up and down, in the process, the second electric rotating shaft 18 at the front side drives the brush on the cleaning roller 19 to rotate anticlockwise (under the front view of fig. 1), the right side surface of the cleaning roller 19 is cleaned, the cleaned impurities are cleaned into the collecting frame 17, and the cleaned impurities are discharged through the left through hole of the collecting frame 17, so that the cleaned impurities on the cleaning roller 19 are prevented from plugging the right side surface of the cleaning roller 4 again, and the new cleaning effect of the brush on the cleaning roller 19 is weakened.
In the process of the rotation of the cleaning roller 19, the brush on the right side in the collecting frame 17 is bent through the cleaning plate 1701, so that impurities adhered to the brush drop off, the adhesion of the impurities on the cleaning roller 19 is avoided, the adhered impurities are reattached to the right side surface of the front side primary filter 4 in the process of the rotation, and the new cleaning effect of the brush on the cleaning roller 19 is weakened.
In the process of up-and-down reciprocating movement of the collecting frame 17, the electromagnetic valve in the first connecting pipe 21 is opened, purified water in the external water tank is sprayed out to the left side surface of the front side primary filter 4 through the high-pressure water gun spray head 22, and impurities in the front side primary filter 4 are backwashed, so that the influence of the impurities in the primary filter 4 on the flow area of air in the ventilating duct 1 is avoided.

In the above process, since the height of the high-pressure water gun spray head 22 is lower than the lower side of the adjacent collecting frame 17, when the cleaning roller 19 is used for cleaning the impurities on the right side surface of the primary filter 4 firstly, the resistance of water flow passing through the primary filter 4 is reduced, the water flow emitted by the high-pressure water gun spray head 22 is convenient to pass through the primary filter 4, and the cleaning effect of the inside of the primary filter 4 is improved.
In the above process, the water flow sprayed by the high-pressure water gun spray head 22 flows into the collecting tank 201 after cleaning the primary filter 4, is discharged into the sewage collecting device through the sewage discharge pipe, so that excessive accumulation of sewage after cleaning the primary filter 4 in the cleaning shell 2 after repeatedly cleaning the primary filter 4 is avoided, and when the liquid level is higher than the upper end of the collecting tank 201, the brush on the cleaning roller 19 thoroughly loses the cleaning effect on the primary filter 4, and the service life of the primary filter 4 is reduced.
After the first electric rotating shaft 15 is operated for a certain time, the controller shuts down the first electric rotating shaft 15 when the collection frame 17 moves down to an initial state.
