Multi-cyclone contaminants collector for vacuum cleaner

摘要

The present invention relates to a multi-cyclone contaminants collector having a plurality of contaminants chambers corresponding to a plurality of cyclones. The multi-cyclone contaminants collector includes at least one first cyclone drawing outside air so as to separate contaminants; at least one second cyclone separating fine contaminants from air discharged from the at least one first cyclone, the at least one second cyclone having a contaminants discharging opening for discharging the separated fine contaminants; and a dust cap disposed at the contaminants discharging opening, the dust cap preventing discharged fine contaminants from entering the second cyclone.
