Abstract

PURPOSE: To cleanly discard dust, by decreasing the adhesion of dust near a discharge port by projecting the air discharge port of another end of an intake pipe from a pre-filter surface in the direction reverse to a main filter and by shaping the discharge port in a trumpet-shaped form.
CONSTITUTION: Dust from a hose connecting port 3 passes through an intake pipe 13 of a main filter 11 through a connecting pipe 4, enters a dust collecting chamber 8 from a discharge port 27 and collides with a guide plate 28. The air currents are changed into turning flows by means of a circular arc-like dash-board 30, and sucked to a gauze portion 24 of a pre-filter 23 along an inner surface of the dust collecting chamber 8. In this case, coarse dust is collected by means of the corner portions of the dust collecting chamber 8 and the pre-filter 23, fine dust is caught by means of the main filter 11 from air currents after coarse dust is collected and clean air passes through a motor fan 2 and is discharged from a discharge port 5. When discarding dust, dust can sanitarily be discarded because dust does not adhere near the discharge port 27.
