Document Type and Number:
WIPO Patent Application WO/2021/201311
Kind Code:
A1
Abstract:
The present invention relates to a cyclone unit and a road surface cleaning device equipped with same. The cyclone unit comprises: a first unit pipe which has a first flow space formed therein and a plurality of inlets formed on the outer circumferential surface thereof so that air forcibly blown from a suction unit can enter the first flow space; a second unit pipe which is provided below the first unit pipe and has a second flow space formed therein so as to communicate with the first flow space, wherein the second flow space is formed such that the inner diameter gradually decreases toward the bottom; and flow guide parts which are installed in the inlets in order to guide the air entering the first unit pipe so that the air flowing into the first flow space flows in a spiral trajectory along the inner wall of the first unit pipe, and foreign substances can be separated therefrom. The cyclone unit and the road surface cleaning device equipped with same according to the present invention cause air suctioned from the suction unit to flow along a spiral trajectory and filter foreign substances therefrom, and thus have the advantage of being able to provide relatively high cleaning efficiency even when used for a long period of time.
