Introduction faucet is based on the principle of infrared reflection When the human hand is placed in the infrared area of the faucet, the infrared emitting by the infrared emitting tube is reflected to the infrared receiving tube due to the shielding of the human hand After being processed by the microcomputer in the integrated circuit, the signal is sent to the pulse solenoid valve After receiving the signal, the solenoid valve opens the valve core according to the specified command to control the faucet to discharge water; When the human hand is detached from the infrared sensing scale, the solenoid valve does not receive the signal, and the solenoid valve core is reset by the internal spring to control the water faucet to turn off

In the 1970s, economically developed countries such as Japan and Europe and America used it in public places to prevent secondary pollution and infections after washing hands, but the water saving function was not given multiple attention But because the sensing faucet skills at that time were not mature, they were not always advancing in the process of implementation and dissertation

The introduction faucet is based on the principle of infrared reflection When the human hand is placed in the infrared area of the faucet, the infrared emitting by the infrared emitting tube is reflected to the infrared receiving tube due to the shielding of the human hand After being processed by the microcomputer in the integrated circuit, the signal is sent to the pulse electromagnetic valve After receiving the signal, the electromagnetic valve opens the valve core according to the specified command to control the faucet to discharge water; When the human hand is detached from the infrared sensing scale, the solenoid valve does not receive a signal, and the solenoid valve core is reset by an internal spring to control the water faucet to turn off. In addition, the sensing faucet also has a sensing section faucet, which is a newly invented high tech product widely used in hotels, hotels, office buildings, and others Places It is beneficial for enterprises to save water and money, and also play a responsibility for water scale cities nationwide With the development of sensing sanitary ware, the sensing water saving faucet is widely used

Induction faucet

Communication power supply or DC power supply, using infrared sensing, water can be reached by hand in the sensing area, and stopped by hand when detached from the sensing area The water switch is automatically completed by the sensor, without touching the faucet, which can prevent bacterial cross infection The machine is controlled by a microcomputer, and the sensing interval is set according to the shape of the basin, without the need for manual adjustment It also has a 1-minute timeout function for washing and stopping water, to prevent the waste of water resources caused by foreign objects in the sensing scale for a long time, alkaline dry batteries (6V, 3V, 4.5V) are used for DC power supply, and a filter screen is installed inside to prevent impurities from entering the electrical valve The cleaning is customary, the appearance is essential, the structure is urgent, and it is suitable for places with dense crowds

1. Due to its large size and unattractive appearance, communication power supply is used, making installation inconvenient There is a risk of electric shock when the power supply comes into contact with water

2. In case of power output or unstable voltage, it cannot be used

3. Infrared sensing is sustainable to the influence of background light and direct sunlight, resulting in flowing water when not in use

4. Slow response, opening too slowly during use, and closing the water too slowly after use

5. The battery life of the induction faucet powered by DC is short, and it needs to be replaced frequently Due to the structural design of the battery box, replacing the battery is not very conservative, which poses a problem for managers

6. The various components of the faucet are not modular, resulting in high development and production costs

7. People are unfriendly with the use of infrared radiation, and there is a series phenomenon of human damage

Due to the numerical defects mentioned above, it has had a negative impact on consumption to a certain extent, which has hinted at the implementation of infrared sensing factors

Since the 1990s, due to the rapid advancement of electronic skills, many improvements have been made in sensing faucet skills

1. The power supply has shifted from communication power to direct current power supply, from DC6V and 4.5V alkaline batteries to now 6V and 4.5V lithium batteries, reducing environmental pollution caused by the use of alkaline batteries and raising concerns about the use of communication power

Instructions for using introduction faucets

2. The structure of the water valve has been significantly improved, with a simple, compact, pressure resistant, and conventional disassembly, installation, and maintenance Together, it has functions such as filtering and checking, with quick opening and closing and minimal power consumption

3. Many infrared control blocks use chip soldered electronic components and microcomputer programs for operation, greatly reducing the size of the infrared control blocks It has advantages such as low power consumption, water resistance, and high temperature resistance Because of the use of digital skills, peripheral circuits are simplified, and functional adjustments are considered, reducing development and production costs

4. Due to the compact structure of the water valve and sensing control block of the sensing faucet, the appearance design is becoming more and more beautiful, gradually becoming a beautiful scene in people# 039; S daily lives

With the gradual modularization and standardization of induction faucet production in our country, the quality of induction faucets has significantly improved, production costs have significantly decreased, and people# 039; S daily quality has improved The star of tomorrow, induction faucets, will be ubiquitous in people# 039; S lives
