Abstract: This invention is a motor rotary device having a pump to enhance pressure of water passing through the interior compartment of the brush. The water, while flowing through a water pipe, is allowed to mix with fluid additive and then flow out from the center portion of the brush. There is a pump located at the water pipe. When the motor rotates in a certain direction, it will allow a moveable sliding shaft to slide to a certain position to move a set of idle gears and make the pump rotate to enhance the water pressure of water pipe's water.

Abstract: A portable electrical brush having a water supply and a liquid additive container having a valve controlled outlet is installed on the casing of the brush assembly. The attachment is provided with a water pipe having a valve and an outlet device, which is connected between a hollow shaft and the water outlet of the brush assembly. A motor, a gear reduction set, and a shaft is mounted the same support plate which is secured to upper and lower casings, and a water pipe is connected between the water inlet at the shaft end and water source valve. The space formed by the upper casing and the lower casing is used for containing the above components. The motor start switch, water source valve, and liquid container valve are installed at the outside of the casing such that they can be operated directly. The brush assembly is located at the outside of the lower casing and is removable from the extended portion of the hollow shaft.

Abstract: A water supply device for vacuum bottle used a space at the bottom outside the inner bottle to install a power driving device to drive a gear. The gear has two magnetic poles provided by a permanent magnetic iron using to repel or attract the other magnetic poles located at the concavity to rotate. These poles use the same shaft with a multiple blade gear, therefore, as the magnetic poles rotate, the water inside the inner bottle can be squeezed and flow out through outlet pipe.
