CYCLONE DUST COLLECTOR OF VACUUM CLEANER

摘要

PURPOSE: A cyclone dust collector increases suction force of air flowing in through a suction inlet to increase centrifugal force to effectively separate dust contained in sucked air. CONSTITUTION: A dust collector includes a dust collecting case, a filter(41) and a protrusion(55). The dust collecting case has a suction inlet and a discharging outlet and forms air flowing in through the suction inlet(36) and containing dust into whirling air current to separate dust. The filter(41) is coaxially installed in the dust collecting case to pass air with dust filtered off. The protrusion(55) upwardly protrudes toward the filter(41) to prevent back flow of dust.
