One side of the ventilation channel 1 is provided as an air suction end 2, and the other side is provided as a filtering end 3. The air suction end 2 on the ventilation channel 1 is in communication with an air suction fan outside. The air suction fan is used to drive the airflow to enter the ventilation channel 1 after passing through the filter screen frame 4. The filter screen frame 4 is provided with a plurality of filter screen frames 4 which are rotatably connected to the filtering end 3. Adjacent filter screen frames 4 are in contact with each other. The filter screen frame 4 is provided with a filter screen.

The deflection mechanism is in contact with the plurality of filter screen frames 4. The deflection mechanism is used to drive the plurality of filter screen frames 4 to rotate. The carrying mechanism is arranged in the air suction end 2. The carrying mechanism is provided with the cleaning mechanism. The carrying mechanism is used to drive the cleaning mechanism to be in contact with the plurality of filter screen frames 4. The cleaning mechanism is used to clean the side of the plurality of filter screen frames 4 close to the air suction end 2. When there are many impurities on the filter screen, the plurality of filter screen frames 4 are rotated by the deflection mechanism. The side with dust is rotated to the side facing the air suction end 2. At this time, the carrying mechanism drives the cleaning mechanism to be close to the filter screen frame 4.
