Touch water-saving tap based on logic amplifying circuit

Abstract

The invention discloses a touch water-saving tap based on a logic amplifying circuit. The touch water-saving tap is mainly composed of a tap body (1), a solenoid valve (2), a relay K, a transformation circuit connected with the solenoid valve (2), a control circuit connected with the transformation circuit, a touch opening contact (3) and a touch closing contact (4), wherein the touch opening contact (3) and the touch closing contact (4) are connected with the control circuit and arranged on the two sides of the tap body (1) respectively. The touch water-saving tap based on the logic amplifying circuit is characterized in that the light beam excitation type logic amplifying circuit is further in series connection between the control circuit and the transformation circuit. By means of the touch water-saving tap based on the logic amplifying circuit, the touch opening contact (3) and the touch closing contact (4) are utilized to collect touch information of a user, the touch information is processed by the control circuit and the transformation circuit to control opening and closing of the solenoid valve, and the opening and closing function of the tap is further achieved. The touch water-saving tap based on the logic amplifying circuit is very high in sensitivity and stability.

Description

technical field [0001] The invention relates to an energy-saving faucet, in particular to a touch-type water-saving faucet based on a logic amplifier circuit. 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. (2) Since the push-type faucet h...
