VACUUM CLEANER HAVING A DUST VISUALIZING UNIT, CAPABLE OF PREVENTING DUST GETTING JAMMED IN A GAP BETWEEN COMPONENTS BY SMOOTHLY MAINTAINING AN AIR FLOW IN THE INSIDE OF THE VACUUM CLEANER

摘要

PURPOSE: A vacuum cleaner having a dust visualizing unit is provided to easily remove dust in the inside of a housing unit of a dust visualizing unit due to external air flowing into the inside of the housing unit because the inside and outside of the dust visualizing unit are connected by rotating a dial unit.;CONSTITUTION: A vacuum cleaner comprises a sucking nozzle(100) and a dust visualizing unit. The dust visualizing unit is composed of an air-dust separating member, a housing unit, and an air guiding unit. The air-dust separating member formed in one side of the sucking nozzle comprises an opening(223) where dust and air are discharged and an air flowing hole. The air flowing hole and the opening are independently arranged so that the air can flow. The air guiding unit is formed in the housing unit to be rotated, thereby selectively guiding air outside of the housing unit to the inside of the housing.;COPYRIGHT KIPO 2012
