ABSTRACT:
A cyclone dust separating apparatus has a first cyclone chamber for separating particles from the externally-drawn fluid by centrifugal force, one or more second cyclone chambers for separating particles from the fluid discharged from the first cyclone chamber by centrifugal force, and one or more third cyclone chambers for separating particles from the fluid discharged from the second cyclone chambers, and causing the fluid to be discharged out via a discharge passage. The second and the third cyclone chambers are arranged in radial relation with respect to the first cyclone chamber, and thus, surround the first cyclone chamber. Therefore, the cyclone dust separating apparatus provides multi-stage centrifugal cleaning process and improved cleaning efficiency, while remaining compact-sized.
