ABSTRACT:
A dust collector with an inbuilt cyclonic water filter, comprising a cup-shaped dust collecting unit, a water filter, a fan, a dust passage, an air flow passage, incoming and outgoing air passages; wherein, the outlets of the water filter open into the inlet of the outgoing air passage, and the outlet of the outgoing air passage is separated from the incoming air passage, passes through the outer wall of the cup-shaped dust collecting unit and is connected to the air flow passage. In operation, dust-containing air enters the dust collecting unit via the incoming air passage at a tangent, and the air flow in the dust collecting unit is whirled downwards into the water of the water filter, thereby, the dust contained in the air is wet and left in the water, while purified air is discharged.
