Problems solved by technology

After long-term use, it is found that since the induction faucet uses the sensor as the input source of its control signal, it often occurs that the sensor cannot accurately sense the gestures of the human body during use, and the water outlet time of the faucet lasts for a short time after the water is discharged. Very well meet people's needs

Embodiment

[0017] Such as figure 1 As shown, the solenoid valve 2 of the present invention is fixed on the pipeline of the faucet 1, that is, the water in the water pipe must pass through the solenoid valve 2 to flow out of the faucet 1. In order to control the opening and closing of the electromagnetic valve 2 conveniently, the present invention is provided with a voltage transformation circuit 3 and a control circuit 4 . The transformer circuit 3 is used to step down the 220V AC power to about 12V DC power for use by the control circuit 4 .

[0018] Meanwhile, the present invention also includes a sensor 7 and a sensing auxiliary circuit connected with the sensor 7 . The sensing auxiliary circuit includes a timer 8, a transistor VT3, a transistor VT4, a transistor VT5, a relay K2, a resistor R2 and a capacitor C2. When connected, the base of the triode VT3 is connected to the output terminal of the sensor 7, its emitter is connected to the base of the triode VT4 after passing through...

Abstract

The invention discloses a touch type water tap water-saving device based on a sensor. The touch water tap water-saving device is characterized by comprising a water tap (1), the sensor (7), a timer (8), a transistor VT3, a transistor VT4, a transistor VT5, a relay K2, a resistor R2, a capacitor C2, an electromagnetic valve (2), a touch open contact (5), a touch close contact (6) and a control circuit (4), wherein the electromagnetic valve (2) is arranged on a pipeline of the water tap (1), the touch open contact (5) and the touch close contact (6) are arranged on the two sides of the water tap (1), and the control circuit (4) is connected with the touch open contact (5) and the touch close contact (6). The touch open contact and the touch close contact are used for collecting the touch information of a user, the opening and closing of the electromagnetic valve are controlled after the touch information of the user is treated by the control circuit and a variable voltage circuit, and therefore the opening and closing function of the water tap is realized. The sensitivity is high, and the stability is strong.

Description

technical field [0001] The invention relates to an energy saver, in particular to a sensor-based touch-type faucet water saver. Background technique [0002] At present, water saving (referred to as "water saving") has become a common topic of great concern. Water-saving slogans are posted in places that require frequent water, such as public toilets. In order to achieve the purpose of saving water, many faucets in public places have been replaced with induction faucets, that is, sensor faucets. After long-term use, it is found that since the induction faucet uses the sensor as the input source of its control signal, it often occurs that the sensor cannot accurately sense the gestures of the human body during use, and the water outlet time of the faucet lasts for a short time after the water is discharged. It satisfies people's needs very well. Contents of the invention [0003] The purpose of the present invention is to overcome the defects that the sensor in the curre...
