ABSTRACT:
The disclosure is directed to a water-powered toothbrush appliance or the like wherein the water-powered motor for driving the toothbrush is mounted in a hand held housing. A valve for controlling fluid flow to the water-powered motor is mounted in the housing and a valve control portion is rotatably mounted by the housing at an area thereof which generally underlies the thumb of a hand holding the appliance. The valve control portion is rotatable by the user's thumb to actuate the valve. In order to efficiently utilize the space within the housing, while maintaining optimum proportions thereof for convenient handling by the human hand, the valve is mounted within the housing on the side of the motor more distant from the valve control portion and the valve control portion is mechanically connected to the valve by an actuator which is arranged to pass directly through the nutating action motor.
