HYBRYD NOZZLE FOR VACUUM CLEANER Russian patent published in 2010 - IPC A47L9/04 

FIELD: personal use articles.

SUBSTANCE: invention is referred to the vacuum cleaner and it's nozzle. The nozzle contains body, rotating brush for surface cleaning and turbine, which is treated by sucked air flow producing torque for rotation of the brush. The nozzle additionally contains electric energy generator for generation of electric energy when rotating the turbine, accumulator for accumulation of electric energy and electric motor which has the ability to create second torque for rotation of rotating brush. Electric motor electrically connected to the accumulator. Electric energy generator can be made in the form of solid element or separate elements. The nozzle is supplied with detector device for detection of values of at least one parametre which defines rotation of the brush and switching device for switching between first and second operating regime. When the first operating regime is active, the generator generates electric energy which is accumulated in the accumulator and when the second operating regime is active, electric motor is supplied by electric energy.

EFFECT: ability to treat surface nozzle of any type without decreasing of suction efficiency when excluding any connected to the network power cables and without work interruption.
