Description

A kind of water dispenser control device of fetching water

Technical field

The utility model relates to the electronic intelligence control device, is specifically related to a kind of water dispenser control device of fetching water.

Background technology

Family/the company that sells in the market is designed to the structure for water tap of switch knob with its delivery port of water dispenser; A hand-held cup places below the tap when fetching water; The another hand then need be pulled down the handle of tap top, and this moment, tap can be opened, and cup begins water receiving.Two hands of this process need user are operated simultaneously and could be accomplished, loaded down with trivial details inconvenience, shortcoming hommization.Induction type drinking machine on the market exists water outlet slow again, and it is slow to cut off the water, and controls shortcomings such as not in place, and expensive price simultaneously is difficult to accepted by most of family/companies.

Summary of the invention

To the defective or the deficiency of prior art, the purpose of the utility model is to provide a kind of intelligent degree double-purpose water dispenser high, that more meet people's habits and customs and demand control device of fetching water.

For realizing above-mentioned technical assignment, the utility model is taked following technical solution:

A kind of water dispenser control device of fetching water is characterized in that, this device comprises microswitch, single-chip microcomputer, triode, operational amplifier, FET, electromagnetic relay and the magnetic valve that connects successively.

The other technologies of the utility model are characterized as:

Said apparatus also comprises an optoelectronic switch, and this optoelectronic switch is connected with single-chip microcomputer.

Above-mentioned single-chip microcomputer is the STC80C51 single-chip microcomputer that Shenzhen macrocrystalline scientific & technical corporation produces.

The control device of the utility model is core with the single-chip microcomputer, rather than the traditional hardware installation, makes the control device of fetching water intelligent more, and safe is easier in the science and technology afterwards promote.When taking water tumbler to remove water receiving, only need bump that microswitch get final product, need not to bump always, beat when leaving behind the water because of there being the control of optoelectronic switch also can not waste water.Overcome the fetch water deficiency of device of existing water dispenser, provide a kind of simple in structure, reasonable price is saved resource, and the device of fetching water that can promote easily.

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the circuit diagram of the utility model;

Fig. 3 is the installation site sketch map of control device on water dispenser of the no optoelectronic switch of the utility model;

Fig. 4 is the installation site sketch map of the control device that optoelectronic switch is arranged on water dispenser of the utility model.

Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.

The specific embodiment

The water dispenser of the utility model control device of fetching water comprises successively microswitch, single-chip microcomputer, triode, operational amplifier, FET, electromagnetic relay and the magnetic valve that connects.As shown in Figure 3 in actual the use, microswitch is installed in the place of the cup that discharges water, and single-chip microcomputer is installed on the water dispenser internal stent, and magnetic valve directly is connected the switch of controlling delivery port with delivery port.But to the hardness requirement to some extent of cup, if cup is soft excessively, big inadequately to the dynamics of microswitch, causes switch can't act under this scheme, relatively is fit to company and family and uses.

Another kind of implementation, as shown in Figure 1, the water dispenser of the above-mentioned the utility model control device of fetching water also comprises an optoelectronic switch, this optoelectronic switch is connected with single-chip microcomputer.As shown in Figure 4 in actual the use; Optoelectronic switch is installed on the delivery port vicinity of water dispenser; Microswitch is installed on the delivery port of water dispenser and locates in the inner part, and single-chip microcomputer is installed on the water dispenser internal stent, and magnetic valve directly is connected the switch of controlling delivery port with delivery port.

This control system considers that the simple realization function expansion convenient and later on possible with control serves as the control core with the STC80C51 single-chip microcomputer, obtains external information through optoelectronic switch and microswitch, and drives magnetic valve and reach and control the purpose that current cut-off.

For the control device that is provided with optoelectronic switch, as shown in Figure 2, the positive termination+5V of optoelectronic switch, negativing ending grounding, photoelectric switching signal termination STC80C51 single-chip microcomputer P1.6 pin; Optoelectronic switch is infrared adjustable digital; Adjustable distance is 0.1cm～50.0cm; The photoelectric switching signal end is a high level when in setpoint distance, there not being object to block then; The optoelectronic switch signal end is a low level when detecting object, the color of shelter and profile to detection sensitivity all to some extent influence but among the design distance of reaction set shorter, so this influence can be ignored;

Microswitch is the microswitch on the common mouse, and is cheaply durable, and the INTO (external interrupt 0) of microswitch one another termination of end ground connection STC80C51 single-chip microcomputer mouthful is the P3.3 pin in the physical circuit;

The P1.5 pin of STC80C51 single-chip microcomputer is connected with triode Q3.

During concrete work, if there is not object contact contact plate, microswitch is not touched, and then the STC80C51 single-chip microcomputer gets into and waits for, does not carry out any operation;

If it is closed to be carved with object contact microswitch when a certain; Loop ground connection; Then a trailing edge initiation interruption appears in the P3.3 pin, and the STC80C51 single-chip microcomputer stops wait-for-response interrupting, and whether be blocked with the machine testing optoelectronic switch is whether the P1.6 pin is low level; If not low level signal, then the 80C51 single-chip microcomputer is judged as rub-out signal and withdraws from interruption continuation wait; If low level signal, whether the 0.1s that then delays time detects the P1.6 pin once more is that low level prevents rub-out signal, if not then withdrawing from interruption; If then be judged as useful signal, low level signal will continue to detect the P1.6 pin, if shelter does not leave; Then the p1.6 pin is kept low level, and low level signal is high level by the upset of P1.5 pin, and this high level signal inputs to triode Q3; Triode Q3 makes the R4 conducting obtain the voltage of nearly 5V; Then 5V voltage is inputed to operational amplifier OP1, export the grid of one+9V voltage to field-effect pipe Q2 through the proportional amplifier in the same way of resistance R 6 and potentiometer R7 formation, the complete conducting of FET also makes the electromagnetic relay excitation; The closing of contact, the solenoid control delivery port flows out for the open mode current; If shelter leaves; Then high level of optoelectronic switch output is to the P1.6 pin of STC80C51 single-chip microcomputer, and with the P1.5 pin low level of overturning back, the electromagnetic relay output broke off once more after the 80C51 single-chip microcomputer detected; The solenoid control delivery port is a closed condition; Stop to supply water, program is jumped out and is interrupted returning to init state simultaneously, and the STC80C51 single-chip microcomputer continues to wait for.

Above control strategy has been accomplished once the someone and prepared water receiving to whole detection control procedures of finally leaving, and is feasible through preliminary test proof scheme, can work.
