    • A powered scrub brush having a power head module, a brush head module, andn extension shaft module. The power head module includes a positive-displacement motor and a flow-control valve. The motor may be coupled directly to the brush head module or indirectly through one or more extension shaft modules. The power head module has a liquid discharge port that is connected to a liquid discharge tube on the extension shaft module that in turn is connected to a liquid sprayer having a nozzle on the brush head module. Mechanical power is transferred from the motor to the brush via an output shaft on the motor, a flexible shaft in the extension shaft module, and a shaft in the brush head module on which the brush is removably mounted. The powered scrub brush is manually operated by regulating a flow-control valve that is connected between a pressurized water source and an inlet port on the motor. As pressurized liquid flows through the motor, the brush will rotate and liquid will be discharged via the nozzle. In an alternate embodiment, the brush is eccentrically mounted for orbital motion. In this version, a counterweight provides dynamic balance.
    • 具有动力头模块,刷头模块和延伸轴模块的动力擦洗刷。 动力头模块包括一个正排量马达和一个流量控制阀。 马达可以直接耦合到刷头模块,或间接地通过一个或多个延伸轴模块。 动力头模块具有液体排出口,其连接到延伸轴模块上的液体排出管,该喷液管又连接到在刷头模块上具有喷嘴的液体喷雾器。 机械动力通过马达上的输出轴,延伸轴模块中的柔性轴以及刷头模块中的可移除地安装的刷子头上的轴传送到电刷。 通过调节连接在电动机上的加压水源和入口之间的流量控制阀来手动操作动力洗刷刷。 当加压液体流过电机时,电刷将旋转,液体将通过喷嘴排出。 在替代实施例中,刷子偏心安装用于轨道运动。 在这个版本中,配重提供动态平衡。
