Automatic water-saving tap

Abstract

The invention discloses an automatic water-saving tap. The tap comprises a tap shell, a ceramic valve plug water control valve, a water control valve handle, a tap water inlet and a tap water outlet, wherein a main water-saving valve water outlet is arranged on a tap water nozzle inner partition; a secondary water-saving valve water outlet is arranged in the bottom of the inner wall of a piston-shaped main water-saving valve water outlet block cover; when the hands hold water below the tap water outlet for washing the face, the fingers push a water-saving valve button, the secondary water-saving valve water outlet is opened first, the pressure above the piston-shaped main water-saving valve water outlet block cover disappears, the main water-saving valve water outlet can be easily opened and water flows out of the tap water outlet, and the fingers leave the water-saving valve button, the secondary water-saving valve water outlet and the main water-saving valve water outlet are closed and the water stops flowing out of the tap water outlet, thus achieving the aim of conveniently saving water with ingenious and simple structure.

Description

technical field [0001] The invention relates to a water-saving faucet, in particular to an automatic water-saving faucet for toilet basins. Background technique [0002] In the prior art, the bathroom faucet for washing the face and hand washing is composed of a faucet housing, a water inlet, a water control valve, a water control valve handle, and a water faucet outlet. The faucet handle is installed at the top of the faucet. The handle of the water valve controls the amount of water, the temperature of the water and closes it. Generally, when washing your face, adjust the handle of the faucet to the appropriate position with your hands, and the water outlet under the faucet will flow out the adjusted water flow downwards, and then wash your face with both hands. Hold the water under the water outlet and wash again, and repeat this until the face is washed before turning off the faucet. But when holding water to wash one's face with both hands at every turn, water flow flo...

Problems solved by technology

However, when washing the face with both hands holding water, the water flows away in vain, causing waste

[0003] The current technical solution to this problem is mainly to use an inductive water faucet, that is, a sensor is installed near the water outlet of the faucet to detect the signal that the hand is approaching the water outlet to prepare for water intake, and the detection result is transmitted to the control electrical appliance, which is then passed through the electromagnetic valve. The valve controls the closing of the faucet, but it cannot be widely used in households due to its complex structure, high cost, poor reliability, and easy failure.
