Abstract
Description
Technical Field
[0001] The invention relates to a solenoid valve, in particular to an infrared inductive solenoid valve. Background Art
[0002] When using sanitary ware in public toilets, if the valve is opened manually to flush the sanitary ware, there will be a risk of cross-infection of germs after many people use it. How to use sanitary ware without contact is of great significance. Summary of the invention
[0003] In order to control the valve flushing of sanitary ware without contact, we have designed a solenoid valve controlled by infrared sensing. The opening and closing of the valve can be controlled by just scanning with your hand, thereby reducing the risk of cross-infection of germs.
[0004] The technical solution adopted by the present invention to solve its technical problem is: the infrared induction solenoid valve includes two parts, a solenoid valve and an infrared sensor, and the infrared sensor and the solenoid valve are connected by wires. The infrared sensor is equipped with an infrared transmitting tube and an infrared receiving tube, which are used for transmitting and receiving infrared rays respectively, and can detect the approaching movement of external objects, and then control the action of the electromagnetic relay behind. The infrared sensor is provided with a delay circuit and an electromagnetic relay, which can delay the control of the action of the electromagnetic relay. After the electromagnetic relay is connected to the solenoid valve through an external wire, the control of the solenoid valve can be realized. The solenoid valve can be a normally closed solenoid valve commonly seen on the market.
[0005] The benefit of the present invention is that after the infrared sensor is connected to the electromagnetic valve for use, the valve can be opened and closed by simply sweeping it with the hand, thereby reducing the risk of cross infection of germs and improving people's healthy living standards.

[0010] See also Figure 1In this embodiment, the infrared induction solenoid valve is composed of two parts: a solenoid valve 1 and an infrared sensor 2. The infrared sensor 2 is connected to the solenoid valve 1 through an external wire 3. The infrared sensor 2 is internally installed with an infrared transmitting tube and an infrared receiving tube, which are used for transmitting and receiving infrared rays respectively, and can detect the approaching movement of external objects, and then control the action of the solenoid valve 1 through the wire 3. The power supply of the infrared sensor 2 is connected from the outside through a power line 4.
[0011] See also Figure 2 , this is the internal circuit diagram of infrared sensor 2. In this example, infrared sensor 2 determines whether there is an object blocking the front by detecting whether the infrared signal emitted by itself is reflected, thereby controlling the switching action of the electromagnetic relay. The entire system consists of four parts: power supply circuit, infrared sensing circuit, delay circuit and switch control circuit. 1. Power supply circuit: J2 inputs 12V power supply, D5 can prevent the power supply polarity from being reversed, R7 is a current limiting resistor, and C2 and C3 are used for filtering. 2. Infrared sensing circuit: U1C, R10, R11, D6, and C4 form an oscillator, which outputs a pulse signal from pin 10 of U1, which is amplified by Q4 and drives the infrared transmitting tube D2 to transmit infrared signals into space. If this signal is not blocked by an obstacle, the infrared receiving tube D1 cannot receive the signal, so the following circuit does not work; when there is an obstacle in front of D2, the emitted infrared signal is reflected by the obstacle and received by D1. The received signal is amplified by Q1 and Q2, and finally the amplified infrared signal is output at the R3 end, and then the frequency is selected by U1A, and the shape is shaped by U1D, and then output at the 11th foot of U1. 3. Delay circuit: The delay circuit is composed of R5, RP1, and C5. Adjusting RP1 can adjust the delay time after each action. The delay time of this circuit is adjustable in the range of 0-40S. Due to the certain error of the component parameters, the delay time of the circuit will be slightly different. 4. Switch control circuit: Q3, Q5, and K1 constitute the switch control circuit. If D1 receives the signal, it will finally output a delayed low-level signal at the 4th foot of U1, so that Q3 and Q5 are turned on and the electromagnetic relay K1 is attracted. D3 is the working status indicator of the electromagnetic relay.
