VALVE DEVICE AND SHOWER DEVICE USING THE SAME

摘要

Each of the valve device and the shower device includes: a valve/shower device main body; a link lever pivotally held in the valve/shower device main body; a weight provided on the link lever; and a ball valve provided between the weight and a pivot axis of the link lever. When the valve/shower device main body is manually caused to move by shaking, swinging, turning, tilting, tapping, or like operation, a kinetic energy imposed on the weight causes the link lever to make a rotational movement relative to the valve/shower device main body, and then the rotational movement of the link lever displaces the ball valve to open or close a valve hole. The valve device and the shower device can significantly facilitate the valve-opening/closing operations, and do not require a special external member for hand- or finger-operation such as a button, a handle or a switch.

主权项

1. A valve device comprising a valve device main body, a fluid passage provided in the valve device main body and having a valve hole, and a valve body for opening and closing the valve hole,
wherein the valve device further comprises a link lever which is pivotally held in the valve device main body and which is equipped with a weight serving as a point of effort, the valve body is provided at such a position that a distance between a pivot point of the link lever and the valve body is shorter than a distance between the weight and the pivot point of the link lever, and when the valve device main body is caused to move, the movement of the valve device main body causes the weight to make a relative movement to the valve device main body, the movement of the weight causes the link lever to make a rotational movement, and the rotational movement of the link lever causes a movement of the valve body to open or close the valve hole.
