Abstract: The invention concerns a device for separating and collecting trash for a trash collecting apparatus such as a vacuum cleaner, said device comprising a first tube with an air intake (13) capable of receiving the air sucked in and an air delivery outlet, a screw (11) substantially axially positioned in said first tube (8a), a second tube (9) with a diameter smaller than the screw external diameter and coaxially located in the first tube (8a) extension, in ventilating communication though one end to the first tube (8a) delivery end and connected by its other end to the suction unit by a first discharge conduit (14). The invention is characterised in that said device comprises a third tube (8b) arranged around the second tube (9) and connected to the first tube (8a) delivery end so as to provide between the second and third tubes (9, 8b) a second conduit for discharging the trash towards a filter and/or a container (10) in a secondary output flow.

Abstract: A device for connecting a dust bag, the device having a mounting flange (1) and a ring (21) capable of being fixed, matching, one to a vacuum cleaner frame or to a removable vacuum cleaner support or to a linerboard, and the other to the dust bag via one of their two faces, the flange (1) and ring (21) being provided with additional matching elements for being mutually maintained by their free face, and with at least a visual mark (4,24) to facilitate their connection. The invention is characterized in that the diameter of the device is twice as much as the length of the assembled device, when the ring (21) and the flange (1) are arranged one on the other. Advantageously, the flange (1) and the ring (32) have a non-planar surface at their free face, resulting from the difference in height of the two parts, for guiding one of the parts onto the other when they are being connected.
