CYCLONE DUST COLLECTOR VACUUM CLEANER

摘要

PURPOSE: A cyclone dust collector for a vacuum cleaner is provided to simplify by improving a structure of a cyclone for collecting entirely a large waste and a fine dust. CONSTITUTION: A cyclone dust collector comprises a primary cyclone body(11), a perforated pipe(13), a secondary cyclone body(21), an exhaust fluid passage(31) and a fan/motor assembly(32). The primary cyclone body(11) for collecting a waste primarily is formed in a cylindrical shape of a cavity. The perforated pipe(13) having a plurality of through hole(13a) for passing only a fine dust and air at an outer circumference surface is formed to extend from a center portion of an upper side of the cyclone body(11) to an inside of the cyclone body. The fine dust is introduced from the primary cyclone body and is collected at the secondary cyclone body(21) of the cylindrical shape communicating to air outlet of the perforated pipe(13). The exhaust fluid passage(31) for guiding air exhausted through the secondary cyclone body(21) is communicated at air exhausting side of the secondary body(21). The fan/motor assembly(32) for generating a suction force is installed at the other end of the exhaust passage(31).
