MULTIPLE-CYCLONE DUST COLLECTOR

摘要

PROBLEM TO BE SOLVED: To provide a multiple-cyclone dust collector capable of improving a fine dust-collection efficiency. SOLUTION: The multiple-cyclone dust collector comprises a first cyclone for centrifuging foreign matters from air sucked, a plurality of second cyclones provided on an upper part of the first cyclone and a dirt collecting unit connected with a lower part of the first cyclone. The second cyclones are adjoiningly disposed in parallel respectively. The axis of spiral motion of air in the second cyclones are so disposed that they actually intersect the axis of spiral motion of air in the first cyclone at a right angle. A main body of the dirt collecting unit is so formed that it functions as a handle. COPYRIGHT: (C)2006,JPO&NCIPI
