Patent

CA 2611679

It is disclosed a vacuum cleaner nozzle (1) comprising a housing (2), a rotatable brush (9) which is adapted to brush a surface, and a turbine (6), wherein a suction air flow impacting on said turbine (6) generates a first rotational torque for rotating said rotatable brush (4), wherein it further comprises an electric power generator (14) for generating electric power by a rotation of said turbine (6); an accumulator unit (18) for storing said electric power,- and an electric motor (14) which is adapted to generate a second rotational torque for rotating said rotatable brush (9), wherein said electric motor (14) is electrically connected to say accumulator unit (18). The electric power generator (14) and the electric motor could be either integrated into a single component or they could be separate components.

L'invention concerne un suceur (1) d'aspirateur comprenant un boîtier (2), une brosse rotative (1) conçue pour brosser une surface, et une turbine (6). Le flux d'air aspiré arrivant sur ladite turbine (6) produit un premier couple de rotation permettant de faire tourner ladite brosse rotative (20). Ce suceur comprend en outre un générateur (14) d'énergie électrique permettant de produire de l'énergie électrique par rotation de ladite turbine (6), un bloc (18) accumulateur permettant de stocker ladite énergie électrique, et un moteur électrique (14) conçu pour générer un second couple de rotation permettant de faire tourner ladite brosse rotative (1). Le moteur électrique (14) est raccordé électriquement au bloc (18) accumulateur. Le générateur (14) d'énergie électrique et le moteur électrique peuvent être soit intégrés dans un seul composant, soit se présenter sous forme de composants distincts.
