Abstract

The utility model provides a touch adjustable type electric-control water-saving valve, which belongs to the field of electronic automatic control. The prior water valve does not have the function of cutting off water automatically. The water-release amount of the prior delay flushing valve is about 8 liter after the delay flushing valve is pressed once, and the delay flushing valve flushes urine and excrement with the same maximum amount of water according to factory design, which is not favorable for saving water. The water valve uses a Quad 2-input NAND gate digital integrated circuit CD4011 as a core for forming a logic control circuit. An electromagnetic water valve utilizes the induction voltage of human body and can be controlled to open only by using a finger to touch a metal touch sheet, so as to flow out tap water. The opening time of the electromagnetic water valve can be conveniently set by rotating a single-pole multi-throw switch before and when the electromagnetic water valve is opened, so as to control the outflow time of the tap water. Once the set opening time is up, the electromagnetic water valve can be automatically closed so as to cut off the tap water, thereby achieving the aim of providing comfort for operation and saving water.

Description

Touch adjustable automatically controlled water-saving valve

Technical field

The utility model relates to the adjustable automatically controlled water-saving valve of a kind of touch.

Background technique

The reasonable utilization of water resources to the country of this serious water shortage of China, more and more becomes the topic of our growing interest.In our daily life, there is the situation of a lot of waste water resources: the 1. floor more than school instruction building three floor, daytime, classmates did not often turn off the tap because of the tap anhydrous outflow afterwards of fetching boiling water because the hydraulic pressure of tap water is little; After but hydraulic pressure increased to evening, water tap is flowing water always just, and on the market water valve does not have to close automatically the function of water at present.2. present delay flushing valve is on the market pushed once, and waterdrainage amount is about about 8L, and the flushing of urinating follows stool to wash used water together, all is to wash by the maximum amount of water of producer's design, is unfavorable for using water wisely.People urgently wish to have a kind of easy to operate, water outlet time convenient adjustable and the water-saving valve appearance of the function of automatic pass water arranged.

Summary of the invention:

Technical problem to be solved in the utility model is: overcome above the deficiencies in the prior art and defective, satisfy people's hope, provide a kind of touch adjustable automatically controlled water-saving valve.This water-saving valve utilizes the induced voltage of human body, only with hand refers to touch, and metal touches the unlatching that sheet just can be controlled the electromagnetism water valve, tap water is flowed out, all can be before the electromagnetism water valve is opened, in opening by rotating single pole multiple throw, set the open-interval length of electromagnetism water valve easily, with the delivery time of control tap water, in case the opening time of electromagnetism water valve arrives the time of setting, the electromagnetism water valve can cut out automatically, thereby the shutoff tap water has reached and has not only operated comfortable but also water-saving purpose.

The technological scheme that its technical problem that solves the utility model adopts is: the adjustable automatically controlled water-saving valve of a kind of touch is characterized in that: opening time many grades of adjustable logic control circuits and controll plant electromagnetism water valve are equipped with in inside.At the input end of logic control circuit metal is housed and touches sheet, be equipped with in the logic control circuit one four or two input nand gate digital integrated electronic circuit CD4011, constitute many grades of adjustable RC delay circuits by single pole multiple throw and Resistor-Capacitor Unit.

The utlity model has following advantage and beneficial effect: utilize the induced voltage of human body, only with hand refers to touch the unlatching that the sheet of metal touch just can be controlled the electromagnetism water valve, and tap water is flowed out; All can be before the electromagnetism water valve is opened, in opening by rotating single pole multiple throw, set the open-interval length of electromagnetism water valve easily, with the delivery time of control tap water, in case the opening time of electromagnetism water valve arrives the time of setting, the electromagnetism water valve can cut out automatically, thereby the shutoff tap water has reached and has not only operated comfortable but also water-saving purpose.The utility model also can be used for the livestock self water feeding of livestock plant, and has and simple, easy to use, cost is installed is no more than 40 yuan advantage.

Embodiment:

Below in conjunction with the drawings and specific embodiments principle of the present utility model and structure are described further.

Fig. 1 is the general structure schematic representation of present embodiment, comprises opening time many grades of adjustable logic control circuit I and controll plant electromagnetism water valve II.

Fig. 2 is the external form schematic representation of the opening time many grades of adjustable logic control circuits of present embodiment, and A is that metal touches sheet, and K is that hilted broadsword is thrown selector switch more.

Fig. 3 is the use flow chart of present embodiment, only with hand refers to touch the sheet of metal touch during use, opening time, many grades of adjustable logic control circuits will be controlled the unlatching of electromagnetism water valve, tap water is flowed out, in case the opening time of electromagnetism water valve arrives the time of setting, the electromagnetism water valve can cut out automatically, thereby turn-offs tap water.

Fig. 4 is the circuit theory diagrams of present embodiment.

In circuit diagram, the 220V electric main is through electromagnetic valve coil L current limliting, diode D2-D5 rectification, resistance R 10 and R9 dividing potential drop, and capacitor C 2 filtering obtain the VDC of about 10V, use for the work of CD4011 integrated package.The input pin of four 2 input nand gates of CD4011 inside all links to each other in twos, becomes four not circuits, is denoted as F1～F4 here.Because the input of F1 at ordinary times through resistance R 2 ground connection, is exported high level, F2 is output low level then, the input of F3 is simultaneously also exported high level through resistance R 4 ground connection, and the F4 output low level is ended unidirectional controllable silicon S CR, the electric current that flows through among the electromagnetic valve coil L is very little, is not enough to action.When the tinsel on the staff touch switch, the voltage of body sense makes F1 input become high level by resistance R 1, thereby output low level, F2 exports high level thereupon, and gives capacitor C 1 charging through isolating diode D1, after voltage rises to a certain degree, the F3 output low level of overturning makes F4 output high level, the SCR conducting, the electric current that flows through among the solenoid valve L sharply increases, and the valve opening solenoid initiating is done.After staff stops to touch, F2 output reverts to low level again, capacitor C 1 will be by slowly discharge of resistance R 4 (or R3 or R5 or R6 or R7), voltage reduces gradually, hang down when arriving to a certain degree F3 upset output high level, F4 output low level, cause unidirectional controllable silicon S CR to end once more when alternating voltage zero-crossing, electromagnetic valve coil L reduces to reset because of the electric current that flows through.Resistance R 11 is indicated as power supply with neon bulb Ne, can be convenient for people to find accurately fast in the dark the position of touch switch.

The length of the time of this touch switch time-delay can be held the resistance that K switch is switched different resistances by hilted broadsword more, obtains different delay times, and the resistance of the R3 to R7 among the figure can be selected according to actual needs, and resistance is big more, and the time of time-delay is just long more.
