Abstract
A water-saving control device and the control method thereof is used in an inflowing waterway. The control device has an internal floating body disposed in an upper cover, a spring and a main body. The upper end of the internal floating body forms a head, which can be hermetically cooperated with an opening of the upper end of the upper cover. The side wall of the internal floating body has a water inlet. The side wall of the lower part of the main body has a flow adjusting opening and the lower part of the internal floating body is movable in the main body for adjusting the flow opening. The lower end of the spring abuts against the inside of the main body while the upper end abuts against the internal floating body to seal the opening of the upper cover.
