Touch type water economizer based on power amplifying circuit

Abstract

The invention discloses a touch type water economizer based on a power amplifying circuit. The touch type water economizer mainly comprises a water tap (1), a sensor, a relay K1, a relay K2, a control circuit, an electronic valve (2), an open touch contact (3), a closed touch contact (4) and a transformer circuit, wherein the electromagnetic valve (2) is arranged on a pipeline of the water tap (1), the open touch contact (3) and the closed touch contact (4) are arranged on two sides of the water tap (1) and connected with the control circuit, and the transformer circuit is connected with the electromagnetic valve (2) and the control circuit. The touch type water economizer is characterized in that a power amplifying circuit is serially connected between the control circuit and the relay K2, and the relay K1 is serially connected between the control circuit and the power amplifying circuit. The open touch contact and the closed touch contact acquires touch information of users and controls on and off of the electromagnetic valve after processing of the control circuit and the transformer circuit, opening and closing of the water tap are realized, and the touch type water economizer is high in sensitivity and high in stability.

Description

Technical field [0001] The invention relates to an energy saver, in particular to a touch type water saver based on a power amplifier circuit. Background technique [0002] At present, water conservation (referred to as "water saving") has become a common topic of great concern. Water conservation slogans are posted in places where water is frequently used, such as public toilets. In order to achieve the purpose of saving water, the faucets in many public places have been replaced with inductive faucets, that is, sensor faucets. After long-term use, it has been found that since the inductive faucet uses a sensor as its control signal input source, there are often defects that the sensor cannot accurately sense human gestures during use, and the short duration of water discharge after the faucet is discharged. It satisfies people's needs well. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the current inductive faucet th...

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
