when the air filter is used, air enters from the air inlet pipe (3), is filtered by the upper filter cylinder (9) and the lower filter cylinder (27) and then is discharged to the air outlet (23) through the detection pipe (31), when the surface area of the upper filter cylinder (9) and the lower filter cylinder (27) is not too much, the air resistance is small, the air flow in the lower filter cylinder (27) is large, the filter screen (32) is pushed to extrude towards the air outlet (23), namely, the connecting plates (34) at the two ends of the filter screen (32) drive the ejector rods (35) to push against the pressure sensors (37), the pressure value born by the pressure sensors (37) is in a normal range, and if the air flow in the upper filter cylinder (9) or the lower filter cylinder (27) is small due to long-time use, the surface dust accumulation is more, the air resistance is large, the air flow entering the interior of the air is small, the air flow discharged into the detection pipe (31) is small, the extrusion force of the filter screen (32) to the air outlet (23) is reduced, the pressure generated by the ejector rods (35) driven by the connecting plates (34) at the two ends of the filter screen (32) to the pressure sensor (37) is reduced, namely, the pressure value born by the pressure sensor (37) is lower than a normal range value, which indicates that the air outlet efficiency of the air filter is low, at the moment, the pressure sensor (37) transmits a signal to the external controller, the external controller controls the driving motor (24) to work, the filter cylinder (27) is driven to rotate by the external controller, and the surface of the air filter is cleaned by the brush (22), so that the dust on the surface of the air filter is cleaned, meanwhile, the operator can be reminded, and the upper filter cylinder (9) needs to be cleaned.
