Faucet water output control system

Abstract

The invention discloses a faucet water output control system used for controlling water output of a faucet. The faucet water output control system comprises an infrared sensor, a controller, an electromagnetic valve and a timer, wherein the infrared sensor is arranged in the position, facing a user, of the front side of a wash stand, and the output end of the infrared sensor is connected with the controller; the electromagnetic valve is arranged in a water pipe and used for controlling flowing of water flow in the water pipe; and the controller is connected with the electromagnetic valve and the timer, controls the electromagnetic valve to open after receiving infrared signals of the infrared sensor, and controls the electromagnetic valve to slowly close after the electromagnetic valve is opened for a preset time according to timing of the timer. By means of the faucet water output control system, a prompt can be given when a water output period is about to be ended, people are reminded to reasonably utilize water flow, and waste of water resources is reduced.

Description

technical field [0001] The invention belongs to the field of automatic control, in particular to a water outlet control system of a faucet. Background technique [0002] Water is the source of all things. With the decrease of fresh water resources, the concept of water saving has penetrated into all aspects of life and production. In addition to improving people's awareness of water saving, people are consciously saving water, enhancing the water saving function of daily necessities, and compulsorily reducing unnecessary Necessary water waste is even more important. As an indispensable washstand faucet, it causes huge waste of water resources. How to enhance its water-saving function is a technical problem that the industry has been exploring and solving. [0003] Chinese patent application number 201510662067.6 discloses an induction delay faucet, which includes a 12V DC power supply, a microwave induction and detection circuit, a monostable delay and an electronically cont...

Problems solved by technology

[0008] (1) The sensor is usually installed on the front side of the faucet facing the user, and the user must reach out to just block the sensing signal before it can be sensed by the sensor, which is very troublesome to use;

[0009] (2) For most users who are accustomed to the manual control structure, since they do not know when to stop the water discharge, a water discharge cycle that is clearly enough for use will make people feel that they have not been cleaned because they have not adapted, and trigger it again Induction produces secondary water discharge. Most of the water flowing out in the second water discharge cycle is useless. In addition, the flow of people in these places is large, and the water consumption is actually doubled, and most of the water consumption is actually wasted. Room for improvement
