Abstract

The invention provides an automatic closing water-saving valve arranged on a faucet. The automatic closing water-saving valve comprises a shell, a bearing, a control rod, a sleeve part and a water inlet seat. When the automatic closing water-saving valve is opened, the control rod can slowly move down due to gravity and a slight water pressure until an upper abut-against part of the control rod seals up a bearing rod hole; then water flowing into a space between the bearing and the sleeve part from a sleeve hole of the sleeve part is gradually accumulated to squeeze the sleeve part upwards and enable the sleeve part to be deformed, so that the sleeve part seals up the water inlet seat to stop the water flow, and thus, an automatic closing effect is achieved. The deformation process of the sleeve part is progressive, and thus, the sleeve part has an effect of buffering to turn off water, so that water hammer sound is avoided. Moreover, the water pressure is not directly acted to the control rod, and thus, a force which needs to be applied when the control rod is operated is small.

Description

technical field [0001] The invention relates to a self-closing water-saving valve installed on a water tap. Background technique [0002] The water pipe control valve in the prior art is installed at the switch on the faucet, which has the advantage of simple structure. However, after people finish washing, they must lift their hands to operate the control valve located above the water pipe faucet. Action will cause the waste of water resources at the same time. [0003] In order to solve the aforementioned problem of wasting water resources, relevant technical personnel have developed an infrared sensor water valve. When people perform washing actions, they can place their hands in the sensing area, and the water valve can be opened through infrared induction; completed After the hand is removed during the washing action, the water valve will automatically close, thereby achieving the effect of saving water; but because the infrared sensing range is a specific area, people...
