Abstract
A cyclone dust-collecting apparatus capable of separately collecting relatively large dust particles and small dust particles, and implementing compact size and light weight thereof comprises a suction air inlet, a first dust-collecting chamber for collecting relatively large dust particles from dust-laden air drawn in through the suction air inlet, a second dust-collecting chamber for collecting relatively small dust particles from the air passed through the first dust collecting chamber, a cyclone generation portion extending across the first and the second dust-collecting chambers to provide fluid communication therebetween, a dust separation assembly formed in the cyclone generation portion configured to collide with the dust drawn in through the suction air inlet and to form a cyclone air stream in the second dust-collecting chamber, and an air discharge pipe disposed in the cyclone generation portion spaced apart from the dust separation assembly.
