The heat dissipation pipe 9 can cool the air used by the heat dissipation fan 3 to a certain extent, and the filter box 10 can filter the dust in the air, effectively reducing the dust from entering the extraction box 102 through the ventilation port 7.
[0026] The mounting frame 2 is provided with a dust removal mechanism for removing dust from the placement slot 101 and the extraction box 102, and the dust removal mechanism includes a collection box 11, a negative pressure fan 12, a dust bag 13 and a bellows 14.
