Abstract
A handheld dust collector, a spiral two-stage tornado dust-air separation structure and a primary dust barrel are disposed in the body of the handheld dust collector. The spiral two-stage tornado dust-air separation structure includes a first-stage cyclone barrel, a second-stage cyclone barrel, a cyclone cover, and a spiral dust-air separation apparatus disposed at the upper end of the second-stage cyclone barrel. The first-stage cyclone barrel and the cyclone cover perform first-stage dust-air separation on primary dust-air entering the spiral two-stage tornado dust-air separation structure, and second-stage dust-air after previous separation enters the second-stage cyclone barrel for second-stage dust-air separation. The dust collector is small in the number of components, simple in assembling procedure, and high in comprehensive performance of a complete machine. The spiral two-stage tornado dust-air separation structure is relatively small in size, and effectively reduces the space of a machine body and achieves a maximum dust storage volume.
