    Abstract: A separator for a vacuum cleaner has a cover part from which webs are projecting which are positioned along the circumference of the cover part at a spacing one behind the other with formation of through openings. At least some of the webs are without connection with each other at the end that is facing away from the cover part. The webs are elastically yielding transversely to the longitudinal direction. The webs are positioned in their mounting position with radial pretension on a spider which is fixedly seated on the motor shaft of the vacuum cleaner. Due to centrifugal forces occurring in operation of the vacuum cleaner as a result of the high rotary speed of the motor shaft, the webs of the separator are positioned with their free ends under high force on the spider. The separator is thus reliably entrained by the spider by friction.

When the switch is in ON condition, the plurality of batteries supply an electrical power to the motor and the motor converts the electrical power into a mechanical power which in turn causes propulsion of the impeller thereby sucking out the air from a water bowl of the smoking apparatus. The propulsive motion of the impeller sucks out the air from the water bowl until the air inside the water bowl is replaced by condensed smoke.

  • Patent number: 8966705
    Abstract: A round-shaped lid with a curved edge and domed air outlets to collect leaves with a blower/vacuum in suction mode. The leaves shredded by the blower/vacuum are discharged into a connecting pipe which is attached to a lid inserted into the opening of a large debris collection bag. In particular, the lid has three main openings, one for the entry of debris and two for the air outlet. The connecting pipe is made of ribbed plastic and is held to the lid by the sides of a groove and to the blower/vacuum by a plastic sleeve with cable ties. A piece of thick plastic or metal is placed under a plastic membrane and the debris collection bag in order to protect them during movement over the ground. The debris is collected directly into the bag that will be discarded.
