Vacuum cleaning tool with electrically driven brush roller
First Claim
1. A vacuum cleaning tool for connecting to a suction tube of a vacuum cleaning device, said tool comprising:
- a casing with a bottom plate facing a floor surface to be cleaned;
a brush chamber enclosed within said casing;
a brush roller having bristles and being rotatably supported within said brush chamber;
an electric motor for rotatably driving said brush roller;
said bottom plate having a suction opening;
said bristles of said brush roller extending through said suction opening;
a speed regulator connected to said electric motor;
a movement sensor for sensing movement of said vacuum cleaning tool across a floor;
a first recognition circuit connected between said movement sensor and said speed regulator for recognizing signals emitted by said movement sensor derived from movement of said vacuum cleaning tool across the floor and sending switching signals derived from the signals emitted by said movement sensor to said speed regulator; and
wherein said speed regulator switches on and off said electric motor based on said switching signals.

Abstract
A vacuum cleaning tool for connecting to a suction tube of a vacuum cleaning device according has a casing with a bottom plate facing a floor surface to be cleaned. A brush chamber is enclosed within the casing. A brush roller having bristles is rotatably supported within the brush chamber. An electric motor drives the brush roller. The bottom plate has a suction opening through which the bristles of the brush roller extend. A speed regulator is connected to the electric motor. A movement sensor for controlling the speed regulator is provided, wherein the electric motor is switched off by the speed regulator as a function of a signal emitted by the movement sensor. A first recognition circuit is connected between the movement sensor and the speed regulator.
