Abstract
A nozzle mechanism for a vacuum cleaner. The mechanism has a sliding base with an intake opening, and a suction conduit connector for a vacuum cleaner. Disposed between the intake opening and the connector is an air feed channel, in the path of which is disposed a turbine chamber having a turbine that can be driven by intake air. The turbine serves for driving a brush roller for mechanically cleaning floors. A second intake opening is provided that is connected to the turbine chamber via an intake channel that is independent of the first intake opening. The air for driving the turbine is supplied to the turbine chamber at least partially via the second intake opening and the intake channel.

In a vacuum cleaner nozzle mechanism having a sliding base with a first intake opening, a suction conduit connecting means for a vacuum cleaner, an air feed channel for establishing communication between said first intake opening and said connecting means, and a turbine that is driven by drawn-in air and serves to drive a brush roller that is rotatably mounted in the vicinity of said first intake opening, the improvement wherein:
- a second intake opening is provided, with an intake channel that is independent of said first intake opening establishing communication between said second intake opening and a turbine chamber for said turbine, with said air for driving said turbine being supplied to said turbine chamber at least partially via said second intake opening and said intake channel, with said air feed channel, which conveys dust-laden air, being disposed between said first intake opening and said turbine chamber, with said air feed channel and said intake channel opening out into said turbine chamber on one and the same side thereof.
