ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a controlling device for a showerhead, and more particularly to a controlling device that allows short people to use the showerhead readily.
2. Description of Related Art
With reference to
FIG. 7
, a conventional controlling device for a showerhead (
70
) is firmly attached to a wall. The controlling device is a valve (
71
) securely and pivotally mounted in the showerhead (
70
) so a person can control water flowing to a first outlet (
72
) or a second outlet (
73
). However, because the showerhead (
70
) normally is attached to the wall high above the ground, short children are not able to reach the valve (
71
) to control the water. Therefore, an adult must assist a child when ever the valve (
71
) must be operated.
To overcome the shortcomings, the present invention provides an improved controlling device for a showerhead to mitigate and obviate the aforementioned problems.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide an improved controlling device for a showerhead. The controlling device enables children to use the showerhead readily.
Another objective of the present invention is to provide a clamping device so that when the controlling device is activated, the clamping device is able to provide necessary force to support the push rod to keep water flowing in a specific direction.
To accomplish the foregoing objective, the controlling device of the present invention includes a push rod, a controlling valve and a collar. The push rod has a head with an annular seal mounted around the head. The controlling valve has a first opening, a second opening communicating with the first opening and a radially defined hole communicating with both the first opening and second opening. The collar is connected to the showerhead body and the controlling valve.
