Abstract
The utility model discloses an automatic timing-control water economizer applicable to public toilets. The utility model comprises an electromagnetic valve, a relay, a timing-control circuit and an enclosure. The water economizer is mounted on the tap-water pipe, and the electromagnetic valve components are controlled by a control circuit (mainly comprising a singlechip) to open and close at set time intervals. Totally 30 optional time intervals are designed for the water economizer, and the desired time interval for control can be input by a keyboard. The advantage of the utility model lies in that a timing-control circuit mainly comprised of a singlemachine is adopted to achieve high automation, sound reliability, a compact structure, small power consumption and long service life.
Description
The utility model belongs to the Full-automatic water-saving device with time control, has particularly a kind ofly adopted one chip microcomputer control, is used for the public lavatory and dashes the just full-automatic water saving device of usefulness.
At present, under the very short situation of China's water resource, water saving fixtures more and more come into one's own.In the public lavatory, in the employed toilet-flushing apparatus, there is considerable place using and hangs rising and the reduction that water tank utilizes the ball float position, open or close the flush port of water tank, play the effect of flushing the toilet.For the purpose that obtains to economize on water, can only regulate the water yield size of water intaking valve, be that the little water yield flows into, after treating water filled with water tank, ball float risen, open flush valve, a large amount of water is directly rushed down sweep away, reach the purpose of flushing the toilet, and for the urinal in the men's lavatory, then be to adopt perforated pipe, make a large amount of outflow of water wash away pool wall.More than the shortcoming of two kinds of method for toilet flushing be not at times, as long as inlet valve is opened, then water just constantly washes away, (as night unmanned use time) also constantly washing away in non-the uses period especially, causes a large amount of wastes of water resource.
The purpose of this utility model be to design a kind of by the time as a kind of control instruction, the logic governor circuit that its control is made up of one chip microcomputer, analyze, differentiate the various instructions of sending by time controller, control the open and close of electromagnetism water valve then, thereby reached the purpose of automatic control water saving.It has overcome the defective that floating ball tank formula structure can not be economized on water.This water economizer is a kind of device that has adopted advanced microcomputer control electromagnetism water valve, has the effect of low-power consumption, high reliability, high life.It is a kind of comparatively desirable water saving device.
The technical solution of the utility model: a kind of public lavatory water economizer of time control comprises that electromagnetism water valve, relay, time control circuit, power supply and outer faucal shell play supporting and connect each assembly.It is characterized in that driving that electromagnetism water valve assembly opens and closes is to be made of time control circuit, relay, power supply unit branch.The output of said time control circuit connects the electromagnetic coil of relay, and relay then is connected the electromagnetic coil port of electromagnetism water valve with power supply, and whole device is powered by power unit.And electromagnetic valve, relay, time control circuit and power unit all are installed in the inside of housing, and housing plays the effect of protection.
The hardware circuit that above-mentioned said time control circuit is made up of components and parts such as one chip microcomputer, time control chip, the digital demonstration of LED, keyboards.The hardware circuit that said one chip microcomputer, time control chip, the digital demonstration of LED and keyboard etc. are formed is to carry out work after software programming.Designing altogether in this time control circuit has 30 alternative periods, can import by the period that digital demonstration of LED and keyboard will be controlled.
Above-mentioned said relay is a controlled member, and it and is connected power supply and electromagnetic valve or close after accepting the control instruction of time control circuit.
Above-mentioned said electromagnetism water valve is a penstock, and it is connected on the tap water pipeline, and when relay during with the power connection of electromagnetism water valve, then the penstock of electromagnetism water valve is opened, can be towards urinal; When relay during with the power-off of electromagnetism water valve, then the penstock of electromagnetism water valve is closed, towards the constipation bundle.
The utility model course of work and operating principle are: the critical piece that the time is controlled the public lavatory water economizer has: time control circuit, LED demonstration, keyboard, relay, electromagnetism water valve, at first import present moment, and then input needs the time period of control from the keyboard of time control circuit.And set this start-up time time period and shut-in time, this time control circuit is provided with 30 controllable time periods altogether.When the time control circuit is determined the opening time of section sometime, promptly send instruction and make the relay adhesive, thereby make the electromagnetism water valve connect power supply, valve open is finished into water.When the time control circuit is determined the shut-in time of this time period, promptly send instruction relay is resetted, thereby make electromagnetism water valve dump and valve-off is finished the process of once intaking.
Superiority of the present utility model is: 1. this water economizer opens and closes water valve and has reached increasingly automated because to have adopted be that the time control circuit and the related device of master element directly is connected on the tap water pipeline with the one chip microcomputer; 2. owing to have nearly 30 control periods time, use period and the non-peak period that can set the peak period arbitrarily use the period; 3. water-saving result is remarkable; 4. low-power consumption, high reliability, can use continuously, the life-span is long.
Further specify present technique below in conjunction with drawings and Examples;
Accompanying drawing 1 is an overall structure schematic diagram of the related time of the utility model controlling the public lavatory water economizer.
Accompanying drawing 2 is an operating principle flow chart of the related time of the utility model controlling the public lavatory water economizer.
Wherein: 1 is the electromagnetism water valve, and 2 is water inlet, and 3 is delivery port, and 4 is shell, and 5 is that LED is digital shows that 6 is keyboard, and 7 is relay.
Embodiment:
A kind of time control public lavatory water economizer (seeing Fig. 1,2), comprise electromagnetism water valve 1 and time control circuit, it is characterized in that driving the electromagnetism water valve and start and being finished by the time control circuit that main hardware circuit and programming software form of closing by one chip microcomputer.Connect the digital demonstration 5 of keyboard 6 and LED on the time control circuit plate, the output of said time control circuit links to each other with the electromagnetic coil of relay 7, and the control end of relay is connected the electromagnetism water valve with power supply.
Being linked with the digital demonstration 5 of LED on the above-mentioned said time control circuit plate, is by 4 LED charactron makeup time display screens.
Be linked with keyboard 6 on the above-mentioned said time control circuit plate, formed by 5 enter key.
Claims (2)
1. a time control water economizer that is used for the public lavatory comprises electromagnetism water valve, relay, time control circuit, shell; It is characterized in that water economizer is installed on the tap water pipeline, and, controlling electromagnetism water valve assembly and in the period that sets, opening and closing based on the hardware circuit of one chip microcomputer and the formed time control circuit of software program of establishment; Designed 30 alternative periods in the time control circuit altogether, can import by the period that digital demonstration of LED and keyboard will be controlled.
