[0023] In actual use, the air supply box 1 is connected to the filter box 3 through the air inlet pipe 2. The air is drawn in by the fan 7 and sent to the connecting pipe 8 for output. The air passes through the sliding frame 4 of the filter box 3 and is filtered by the filter frame 5 on the sliding frame 4. When the filter frame 5 needs to be replaced, the upper part of the sliding frame 4 is pulled out from the filter box 3, and the connector is engaged with the anti-detachment groove. At this time, the bottom wall of the bearing groove of the sliding frame 4 is exposed, and the filter frame 5 can be disassembled and replaced, which is convenient to use. The air inlet pipe 2 is equipped with a switch valve 9 so that the air inlet pipe 2 can be closed when the filter frame 5 is replaced.
