Filter and amplification contact type water-saving tap based on logic protection emitter coupling

Abstract

The invention discloses a filter and amplification contact type water-saving tap based on logic protection emitter coupling. The filter and amplification contact type water-saving tap is mainly composed of a tap body, a solenoid valve, a relay K, a voltage transformation circuit connected with the solenoid valve, a control circuit connected with the voltage transformation circuit, a touch open contact and a touch closed contact and further provided with a filter and amplification circuit, a beam-emission type logic amplification circuit and a logic protection emitter coupling type amplification circuit, wherein the touch open contact point and the touch closed contact are connected with the control circuit and arranged on the two sides of the tap body. By means of the filter and amplification contact type water-saving tap, signals can be well filtered and amplified, the adaptive capacity and accuracy of products are improved greatly, the touch open contact and the touch closed contact are adopted for collecting touch information of users, the information is processed through the control circuit and the voltage transformation circuit and then used for control over opening and closing of the solenoid valve, and accordingly opening and closing functions of the tap are achieved. The filter and amplification contact type water-saving tap is very high in sensitivity and very high in stability.

Description

technical field [0001] The invention relates to an energy-saving faucet, in particular to a filtering and amplifying touch-type water-saving faucet based on logic protection emitter coupling. 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, the faucets in many public places have been replaced with push-type or induction-type faucets. After long-term use, it is found that the push-type faucet still has the following defects in actual use: (1) Since the internal water control part of the push-type faucet is a mechanical structure, its internal mechanical structure is easily damaged under long-term external pressure. Then the water source cannot be completely shut off, resulting in the situation that the water source continues to flow out and be wasted. ...
