Abstract:
A device for a vacuum cleaner comprising a cyclone separator having a cyclone comprising a first end wall (35), a second, opposite end wall (135), and an intermediate part (38,130), said intermediate part being either shaped as a cylinder or, at least partly, a truncated cone, the intermediate part has a particle outlet opening (39,131) through which particles separated by the cyclone leave from the intermediate part toward the second end wall, the cyclone, close to the first end wall, being provided with a generally tangentially-directed air inlet (33,129) for dust laden air and having a tube-shaped air outlet (50,142) extending from the first end wall (35) into the intermediate part and communicating with a vacuum source (15,111), wherein said particle outlet opening (39,131) continues into a separation part (40,134) having a side wall opening (41,137) through which particles leave generally perpendicular to an axis of rotation (R) of a vortex created in the cyclone to a particle collecting (27) container placed outside the separation part (40,134).
