NON-POWERED AIR FILTERING APPARATUS USING CYCLONE STRUCTURE

摘要

PURPOSE: A non-powered air filtering apparatus using a cyclone structure is provided to allow a user to operate the device without power by using the flux of inflow air. CONSTITUTION: A fine dust reduction device adopting a non-power cyclone includes a body(2) having a plurality of penetration holes in axial direction. In the penetration holes, cyclonic flow formation member guiding inflow air to be rotated along fane of a shaft attached the side of the shaft and an outlet port is arranged in rear part of the body. A collection space(30) is formed between penetration holes and the outlet port.
