<P>PROBLEM TO BE SOLVED: To provide a water-saving device which generates supersonic vibration to enhance cleaning effect, by reason that water is prevented from leaking from a hole for mixing air, a secondary water flow is generated not to impair use feeling, fine air bubbles are mixed into the water, and the fine air bubbles are blown out. <P>SOLUTION: A water-saving device is configured in such a manner that electrostatics is utilized for an opening/closing structure of an air inlet 3, and the air inlet 3 is opened when water passes and closed when water is cut off, thereby preventing water from leaking from the air inlet 3. As a measure against deterioration of use feeling, a flow of fluid is reduced at an inflow entrance 4 and accordingly flowing water increased in flow rate passes through a rectification hole 5, and an air supply pressure by the sir inlet 3 and a liquid supply pressure by the flowing water are made to act in a flow hole 6 to generate fine air bubbles, while significantly saving water and without impairing the use feeling. Furthermore, cleaning effect can be improved by supersonic vibration generated in association with blowout of the fine air bubbles. <P>COPYRIGHT: (C)2013,JPO&INPIT |
