Abstract

PURPOSE: To control sucked air flow in a dust collecting case and press collected dusts by a force applied from the periphery of the case, by shaping a large dust filter like a cone whose top is located at the side of an inlet port and forming blades integrally with the slope of the cone.

CONSTITUTION: Two blades 18 are radially provided along the conical slope of the primary filter 10 shaped like a cone whose top is located at the side of the inlet port 5. The blades 18 symmetrially extend from the center along curves. In cleaning, the air flows from the inlet port 5 and swirls in the same direction as the inflow to deposit the dust collecting case by the centrifugal force and then passes through the primary filter 10 and a secondary filter 14. When the custs are dropped down, small dusts are flipped down by a dust removing member 24 under the revolution of a knob 12 and large dusts are pressed in a large opening 25 and a small opening 26 by the interlocked revolution of the primary filter 10 and the blades 18. To discharge the dusts to the outside, the knob 12 is revolved and the blades 18 are revolved by the action of a fixed blade 19.
