Controlled silicon is controlled by means of the principle of the change of sensitizing resistance of a light activated element, and the switching on and the switching off of the photoelectric control of the electromagnetic valve can be realized. The utility model has the advantages of simple circuit, no electricity consumption, few element, low cost, high sensitivity, reliable operation, simple assembly, electricity saving, water saving, etc.
Description
The utility model relates to a kind of automatic faucet light-controller.Be specially adapted to the control of public place tap.
At present, faucet controller has a variety of, all has special-purpose low-tension supply, special light source as light-operated, infrared, induction etc., consuming electric power, and technical sophistication is made shortcomings such as difficulty, causes to apply to be subjected to certain restriction.
The purpose of this utility model is to propose a kind of automatic faucet light-controller that power source special, technology are simple, easy to make, be easy to apply that do not need.
For achieving the above object, the technical solution adopted in the utility model is that this automatic faucet light-controller is made up of power supply (3), light-operated box (2) and electromagnetically operated valve (4).Light-operated box (2) is made up of bidirectional triode thyristor (5), one-way SCR (8), rectifier diode (7), light-sensitive element and resistance.
Its circuit connecting mode is that electromagnetically operated valve (4) constitutes ac circuit with bidirectional triode thyristor (5); By electric current through rectifier diode (7) rectification after resistance (9), one-way SCR (8) anode, negative electrode connect the control utmost point (15) of bidirectional triode thyristor (5), constitute the control loop of bidirectional triode thyristor (5); The control loop of one-way SCR (8) is made of to the control utmost point (14) of controllable silicon (8) light-sensitive element (10), resistance (11), resistance (12) order; End by light-sensitive element (13) one ends and resistance (11), resistance (12) joins, and the other end of light-sensitive element (13) joins to constituting with bidirectional triode thyristor (5) negative electrode (16) again and divides a hydraulic circuit.
Automatic faucet light-controller of the present utility model has following advantage:
1, with low cost, install simple and convenient, reliable operation.This circuit only adopts light-sensitive element and controllable silicon, and circuit is simple and direct understands that no misoperation need not debugged, and the work that gets final product is installed.
2, energy-conservation, because this controller does not need special light source and special low-tension supply, so have the advantage of saves energy.
3, unglazed automatic cut-off function can reach reliable water saving.
4, water automation function has realized that water does not lift a hand, and washes the imagination that you just walk.
Fig. 1 is an automatic faucet light-controller circuit diagram
Fig. 2 is an automatic faucet light-controller scheme of installation
Below in conjunction with accompanying drawing the utility model is described further:
The related automatic faucet light-controller of the utility model is made up of power supply (3), light-operated box (2) and electromagnetically operated valve (4).Light-operated box (2) is made up of bidirectional triode thyristor (5), one-way SCR (8), rectifier diode (7), light-sensitive element and resistance.
As Fig. 1, electromagnetically operated valve (4) constitutes ac circuit with bidirectional triode thyristor (5); By electric current through rectifier diode (7) rectification after resistance (9), one-way SCR (8) anode, negative electrode connect the control utmost point (15) of bidirectional triode thyristor (5), constitute the control loop of bidirectional triode thyristor (5); The control loop of one-way SCR (8) is made of to the control utmost point (14) of controllable silicon (8) light-sensitive element (10), resistance (11), resistance (12) order; End by light-sensitive element (13) one ends and resistance (11), resistance (12) joins, and the other end of light-sensitive element (13) joins to constituting with the negative electrode (16) of bidirectional triode thyristor (5) again and divides a hydraulic circuit.
As Fig. 2, during installation, light-sensitive element of the present utility model (10) and light-sensitive element (13) place (2) two position sensitization of light-operated box respectively, other element is all with the plain fat sealing of epoxy in the light-operated box (2), draw with two leads, light-operated box (2) places near the pond (1), and the appropriate location of light source is arranged again, conveniently is advisable with water.
During use, when illumination, electric current is by negative electrode (16) circulation of rectifier diode (7), light-sensitive element (10), resistance (11), light-sensitive element (13), bidirectional triode thyristor (5), and bidirectional triode thyristor (5) and one-way SCR (8) all no current flow through and end, not water outlet of electromagnetically operated valve (4).
When light-sensitive element (13) by being covered light source, when resistance became big, electric current provided trigger current by rectifier diode (7), light-sensitive element (10), resistance (11), resistance (12) for one-way SCR (8), made one-way SCR (8) conducting; Electric current by rectifier diode (7) through resistance (9) and one-way SCR (8) to the control utmost point (15) of bidirectional triode thyristor (5), make bidirectional triode thyristor (5) conducting, electromagnetically operated valve (4) has electric current to flow through promptly to there are flowing out.
When no light source (as night), when light-sensitive element (10) resistance became big, the control loop no current flow through, and bidirectional triode thyristor (5) and one-way SCR (8) all end, not water outlet of electromagnetically operated valve (4).
Each component installation location in the utility model and the scope of application of this controller are not limited to the described scope of embodiment.
