Do you know the delay faucet? Do you understand? I believe that everyone will encounter some embarrassing problems when using ordinary faucets. For example, if the hands are covered with dirty things, if you turn on the faucet, you have to touch the faucet, which will also pollute the faucet. At this time, the editor recommends the delay faucet for you. Let's take a look at the principle of the delay faucet.
The principle of the delay faucet - what is the delay faucet
There are many types of time-delay faucets, including mechanical ones and infrared ones. The time-delay faucet has the characteristics of time-delay, self-closing, hygienic, not limited by hydraulic power, and the water-saving effect reaches 50%. Just one click or the faucet turns on when the body is close, and it can be automatically turned off after leaving, which is convenient and prevents cross-contamination. However, the fly in the ointment of the time-delay faucet is that the water output cannot be adjusted at will and there is no self-locking function. The delay time is also fixed, and often the water stops before washing hands, which is very inconvenient to use, or people leave and the faucet is not turned off, resulting in waste of water resources, and the scope of application is limited to a certain extent sex.
The principle of the delay faucet - what is the principle of the delay faucet
The time-delay faucet is based on the principle of infrared reflection. When the human hand is placed in the infrared area of the faucet, the infrared rays emitted by the infrared emitting tube are reflected to the infrared receiving tube due to the blocking of the human hand, and are sent through the signal processed by the microcomputer in the integrated circuit. To the pulse solenoid valve, the solenoid valve receives the signal and opens the valve core according to the specified instruction to control the water from the faucet; when the human hand leaves the infrared delay range, the solenoid valve does not receive the signal, and the solenoid valve core is reset by the internal spring. Control the water off of the faucet.
AC and DC power supply, battery backup, water comes when you extend your hand, and stops water when you close it, especially water-saving. The switch of water is automatically completed by the delayer, without touching the faucet, which can effectively avoid bacterial cross-infection. The machine is controlled by a microcomputer, according to the washbasin The shape determines the best delay distance, no manual adjustment is required, and it also has a 1-minute overtime washing and water stop function to avoid waste of water resources caused by foreign objects in the delay range for a long time.
