A shower head adapted to mix and dispense a detergent and water is disclosed. A rotational shaft with impeller blades mounted on one end and a rotary brush engaging a detergent bar on the other end is rotated in a shower head when water under pressure flowing through the shower head impinges on the blades. Means are employed to keep the rotary brush in contact with the detergent bar when the detergent bar is being consumed during use. Means for diverting water toward or away from the impeller blades are also provided so that a bather may adjust the shower head during use to provide water or a mixture of water and a detergent.
A turbine driven rotating brush includes a turbine enclosed in a housing having an inlet for receiving water and an outlet for discharging water flow. A port in the housing directs water onto blades of the turbine. A reduction gear transmits the torque output of the turbine to a shaft on which the brush is mounted. The turbine may be located adjacent a backstop so that water exiting the housing through the outlet is incident on the backstop. The backstop breaks up the discharge of the flow of water outwardly away from the brush for achieving different spray patterns around the brush.
