Touch type water tap water-saving device based on sensor

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...
