ABSTRACT:
This invention discloses a subsection dedusting device for a vacuum cleaner comprising an upper cyclone separator including a wind outlet and several lower cyclone separators located below said upper cyclone separator, wind inlets of said lower cyclone separators in fluid communication with said wind outlet of said upper cyclone separator, thereby increasing wind quantity while reducing the whole bulk of the machine, and keeping a relatively high dedusting efficiency, and besides the lower cyclone separator of the present invention adopts a pervasion construction, and air flow rotates in a decelerated and acentric state in the conical barrel, thereby the pressure loss of the air flow is little, and accordingly, obtain a good dust suction effect.
