Problems solved by technology

[0003] In order to solve the problems of the traditional manual contact water flow valve, which is easy to spread germs, and the inductive electronic control system, the control synchronization is poor, the water output cannot be controlled, and it is difficult to popularize in the family. Gear Synchronous Flow Control System
[0004] The beneficial effects of the present invention are: using the working principle Y=A+B+C of the three-input NOR gate, the synchronous control of the outlet water flow and the control of different gears are realized through three three-input NOR gates, which solves the problem of inductive The electronic control system has poor control synchronization and cannot control the amount of water output; the switch of the present invention adopts a touch switch, which avoids the problem of secondary pollution of the user by germs; in addition, the present invention is simple in structure and easy to implement, and can be widely used in It is used in public places and extended to households. It is easy to control and meets hygienic standards, so as to achieve the purpose of efficient and water saving.

Description

technical field [0001] The invention relates to a device capable of synchronously controlling water discharge and having gears for adjusting water discharge. Background technique [0002] At present, in the field of water flow terminal control, two control methods are mainly used: one is the traditional manual contact water flow valve; the other is the non-contact water flow electronic control system controlled by electronic sensors. But they all have their own shortcomings: First, although the water flow controllers such as traditional faucets are convenient, they must be rotated or pressed by the user during use, resulting in unavoidable contact between the human body and the control parts, which is easy to spread germs , which affects the safety and health conditions to a certain extent; although the second type of inductive electronic control system avoids the direct contact between the human body and the water flow output equipment by using the inductive device, and sol...
