Abstract: A cleaner head for a vacuum cleaner houses a hollow brush bar mounted for rotation about an axis. This brush bar is driven by a motor housed inside the hollow brush bar, the motor forming part of a drive assembly supported at one end of the cleaner head. The brush bar is arranged for removal from the cleaner head by sliding the brush bar along the axis and out through an opening at the opposite end of the cleaner head and the brush bar is rotatably supported in clearance around the drive assembly by a first bearing, which bearing engages the brush bar in a corresponding axial-sliding fit to allow said sliding removal of the brush bar.

Abstract: A cleaner head for a vacuum cleaner has a dirty-air inlet provided in a main suction chamber of the cleaner head, an outlet duct extending from the main suction chamber for connection to a suction source, and a rotating brush bar housed inside the main suction chamber for agitating a floor surface contacted through the dirty-air inlet. The brush bar is driven by an air-cooled motor housed inside a hollow section of the brush bar, the motor having an air intake and an air exhaust fluidly connected to one another to form an air cooling path through the inside of the motor. The air intake is connected to a clean air inlet on the cleaner head and the air exhaust is fluidly connected to the outlet duct by an exhaust duct which bypasses the main suction chamber.

Abstract: A hair straightening apparatus having two arms pivotably coupled together and arranged to receive hair within a cavity formed between them is disclosed. A plenum in at least one arm includes an air inlet for receiving airflow from a fan unit and an air outlet for emitting airflow towards hair within the cavity. The air outlet extends along the inner wall of at least one of the first arm and the second arm and is adapted to direct airflow towards a lower edge of the arms.

Abstract: A dental cleaning appliance includes a handle and a fluid delivery system. The fluid delivery system includes a nozzle for delivering a burst of working fluid to the teeth of a user. A contact member for engaging the teeth of the user is moveable relative to the nozzle as the appliance is moved along the teeth of the user. A sensor provides an output which varies with movement of contact member relative to the nozzle. A control circuit actuates the delivery of working fluid to the teeth of the user depending on the output from the sensor.

Abstract: A fluid delivery system of a dental cleaning appliance includes a fluid inlet, a pump for drawing a working fluid through the fluid inlet, a hydraulic accumulator for receiving working fluid from the pump, a nozzle having a fluid outlet, and a valve located between the accumulator and the nozzle. The valve has an open position for enabling the accumulator to deliver a burst of working fluid to the nozzle, and a closed position for enabling the accumulator to be replenished under the action of the pump. A control circuit actuates the pump and controls the position of the valve.
