At the same time, the hydraulic telescopic rod can adjust the position of the dust cover to adapt to the height of the paper to be dusted on the workbench, without manual operation, convenient and fast, saving time and effort, the adsorption is clean and thorough, and the work efficiency is high;

2. The utility model can increase the adsorption area of the dust collection cover on the dust and other sundries generated on the workbench by setting the dust collection cover as a trumpet shape, thereby improving the adsorption efficiency of the dust collection cover, and further reducing the dust, dust, etc. The sundries are absorbed cleanly;

3. The utility model is provided with a filter screen layer at the front end of the air inlet of the exhaust fan, which can intercept the large particle debris in the exhaust pipe and prevent the large particle debris from damaging the normal operation of the exhaust fan;

4. The utility model is equipped with an electrostatic dust removal net in the dustproof frame, which can further absorb dust and other sundries that may not be absorbed by the dust collection cover, so as to ensure that the dust and dust and other sundries are cleaned up and the dust removal effect is improved. ;
