Description

The full-automatic multi-functional Energy-saving water valve

The utility model belongs to the energy saving device technical field, relates in particular to a kind of full-automatic multi-functional Energy-saving water valve.

Present most running water valve is traditional mechanical type valve, has many shortcomings, aspect health care, is the approach of transmission especially.Rarely seen a kind of contactless water valve from the beginning is external import on the existing market, is moment start-stop formula, and when hand enters water discharge of water faucet within the sensing scope, current stop after hand leaves, shortcomings such as having function singleness, cost an arm and a leg, practical face is narrow.

The purpose of this utility model just provides a kind of full-automatic multi-functional water valve, the not public as yet mistake of this Energy-saving water valve.

Task of the present utility model is finished like this: in the system of the moulding water tap that is connected with water pipe, placed solenoid valve, infrared transmitting tube and infrared receiving tube, its guide line is connected with control circuit in the power box by multicore rubber shielding wire.Have power switch, the power box of the tutorial light that powers on, control circuit, electrode plug can be directly and 220 volts power lines grafting.Wherein control circuit is by infrared emission drive circuit, infrared reception change-over circuit, has the audio decoder IC of phaselocked loop ₁, single bistable circuit, photoelectric coupling switch IC of triggering ₃, composition such as controllable silicon SCR.Motionless in hand is put into water tap below distance sensing, the infrared light that infrared transmitting tube sends is reflected, and is received by infrared receiving tube, converts electrical signal to, adds to audio decoder IC through amplification ₁Input end (3 end), as the frequency and the IC of 3 end input signals ₁Self-oscillation frequency when consistent, IC ₁Output terminal (8 end) become low level by high level, this low level signal divides two-way output: the one tunnel send single bistable circuit that triggers, by NE555IC ₂The list of forming Deng element triggers bistable circuit, after working on power, and IC ₂3 ends be high level output, can not trigger by the coupled IC of resistance ₃, existing owing to sending low level signal to give single bistable circuit that triggers, so IC ₂3 ends still be high level after conversion; Photoelectric coupling switch IC is directly triggered on another road ₃, make to be connected IC ₃The controllable silicon conducting of output terminal, the solenoid valve that links to each other with controllable silicon gets electric work, and the water pipe current flow out.As hand leaving water tap below distance sensing, IC ₂3 end no signals inputs, IC ₁8 ends recover high level, the solenoid valve dead electricity, the water pipe current are closed.When shaking in the distance sensing below water tap, hand makes a movement, then IC ₁8 end output low level pulse signals, bistable circuit upset, IC ₂3 ends become low level by high level, IC ₃Be triggered, the controllable silicon conducting, solenoid valve gets electric water pipe water outlet, and keeps this working state; When shaking in the distance sensing again, water makes a movement IC below water tap ₁8 ends export a low level pulse signal again, bistable circuit overturns once more, IC ₂3 ends become high level by low level, solenoid valve dead electricity water pipe current are closed.

The utility model full-automatic multi-functional Energy-saving water valve utilizes a pair of infrared senor, a cover control circuit, by design dexterously, reaches multi-functional effect, but has realized not only can washing one's hands but also the demand of water receiving.Select for use to exchange the 36V inlet valve on the washing machine, can make the water tap of small but excellent U.S. of the system of moulding, and can directly be connected with water pipe as solenoid valve of the present utility model.Place the power box of control circuit, three utmost point latches are arranged, can directly peg graft with 220 volts of power circuits; and be provided with safety grounding protection; and be connected by multicore rubber shielding wire with water tap, make power box, thereby further improved the working life and the reliability of water valve away from the water source.The utility model is simple in structure, with low cost, multiple functional, can satisfy the Consumer of different levels.
