The faucet is composed of a main body, a valve core, a handle, a water filter and other parts.
Working principle: Change the "pipe flow" of water at the outlet of the faucet to " "Line flow", and then the "line flow" is changed into "jet flow" through the pressure of the air. The pressure of the air makes the water dynamic, and reduces the flow of water and increases the pressure of the water flow.
It can easily replace the ordinary filter device in the original faucet spout, and can match international standard size faucets. A correctly installed water saver will allow users to experience the huge difference before and after use in a short period of time: reduced water bills, reduced energy consumption, and increased water outlet pressure.
This water saver reduces the original multi-layer steel wire filter, which can effectively prevent the accumulation of dirt and eliminate the possibility of bacterial breeding. It is equipped with a patented wrench for easy disassembly and cleaning, and is highly efficient in water conservation. It saves energy while effectively maintaining human health.
When this valve is used, the valve core of the valve enters the water outlet, so the water outlet pipe is in a semi-closed state. Therefore, when the control of valve 1 remains unchanged, the water flow is blocked in valve 2, and the water The flow rate will become smaller and the momentum of the water will become larger.
Features: Use simple methods that are easily accepted by consumers to create energy-saving and efficient faucets.
Description: Connect a valve in series to the water outlet of the faucet. If you need to increase the momentum of the water flow, you can control the valve and adjust the flow and momentum of the water by adjusting the size of the water outlet.
The time-limited infrared water-saving faucet has the following characteristics: 1. It is opened by human body induction and automatically closes when the person walks away; 2. If the time limit has expired but the person washing hands has not left, the faucet will automatically close, thus achieving The purpose of saving water.
Working principle: The device mainly consists of infrared detection, time-limited control, execution and power supply. After the mains power is stepped down by C1, rectified by VD1, stabilized by DW and filtered by C2, a 6V voltage is obtained for circuit use. Infrared detection is completed by IC1. IC1 is an ultra-small pyroelectric integrated infrared sensor AMN1 recently launched by Panasonic of Japan. It is packaged in a TO-5 metal shell and has strong anti-interference ability. The static operating current is only about 170μA.
When the human body is close to IC1, its output terminal outputs a high level, causing BG1 and BG2 to be saturated and turned on one after another. The time base integrated circuit IC2 connected to the timer is powered to work, and the power is supplied to the capacitor C4 through R5. Charge. At the beginning, the low potential of the positive terminal of C4 cannot be mutated, pin 3 of IC2 outputs high level, the light-emitting diode in the thyristor photocoupler IC3 emits light, the built-in thyristor is turned on, and the trigger power thyristor SCR is turned on. The solenoid valve DF-1 is electrically activated to open the faucet. When the person leaves IC1, IC1 outputs a low level because it cannot detect the infrared rays emitted by the human body. BG1 and BG2 are cut off one after another, IC2 loses power, IC3 and SCR are also cut off one after another, and the faucet is closed.
During the process of opening the faucet, as C4 continues to charge, the potential of pins 2 and 6 of IC2 gradually increases. If the person using the faucet does not leave, the potential of pins 2 and 6 of IC2 will rise. When the voltage reaches 2/3Vcc, its pin 3 changes to low level, IC3 and SCR are cut off, and DF-1 forcibly closes the faucet, thereby ensuring water conservation. Once the person leaves the faucet, IC2 loses power, and the charge on C4 is immediately discharged through the interior of IC2 and VD2 and R8. The above process will be repeated when the follower uses the faucet.
Installation and production: All components can be soldered on a small circuit board and placed in the wall switch box next to the faucet. A hole of appropriate size is drilled on the switch board so that the sensor lens can receive the close signal. Infrared rays emitted by the human body. Since the horizontal detection angle and vertical detection angle of the sensor can reach 100° and 82° respectively, and the maximum detection distance is up to 5 meters, in order to avoid malfunction, a baffle should be set at an appropriate position in front of the lens so that it can only Receives infrared radiation signals from people near the faucet.
After the production is completed, just adjust the resistance of resistor R5 appropriately so that the time limit is the normal hand washing time. No need to debug the rest.
