Multi cyclone dust-collecting apparatus

摘要

A multi cyclone dust collecting apparatus comprises a multi cyclone unit having a first cyclone and a plurality of secondary cyclones. The first cyclone separates relatively large particles whereas the secondary cyclones separate out smaller particles. The cyclones are under a top cover mounted on a top portion of the multi cyclone unit and having a plurality of connecting covers forming a connecting path for guiding air flowing out of the first cyclone to the secondary cyclone, and a discharge cover forming a discharge path for guiding air flowing out of the secondary cyclone to the outside. The connecting covers and the discharge cover are integrally formed. A contaminant collecting unit is mounted to a bottom portion of the multi cyclone unit and collects contaminants separated from the first cyclone and the secondary cyclones.
