Energy-saving air purification device for clean laboratory

The invention relates to the technical field of air purification devices, in particular to an energy-saving air purification device for a clean laboratory, and provides the energy-saving air purification device for the clean laboratory in order to solve the problems that the air purification range is limited, filter holes can be blocked after long-time filtration of a filter, the filtering effect is poor, and the purification efficiency is reduced. Comprising a base, a multi-stage lifting rod is arranged at the upper end of the base, a top plate capable of moving up and down and rotating is arranged at the top of the multi-stage lifting rod, and a dust collector is arranged on the top plate; when the dust removal disc moves downwards, a structure that the arc-shaped scraper moves downwards along the outer surface of the filter cover and the straight scraper rotates and moves along the lower end surface of the filter cover can be formed; a detachable filter bottle is further arranged on the top plate, the bott
