Background technology

Present known touch delay electronic switch now has been widely used in various place.As the passageway, corridor, public bath room, corridor mouth etc., himself advantage and use value have been demonstrated fully, it mainly is made up of control circuit, load, shell three parts, is exactly to carry out break-make control to the load of heat radiation light sources such as ordinary incandescent lamp bubble but this touch delay electronic switch has a fly in the ointment only, like this consumer selection with use different light sources on be subjected to placing restrictions on and retraining, be difficult to satisfying personalized requirement, also wasted the energy of a large amount of preciousnesses simultaneously.

Summary of the invention

In order to overcome the existing deficiency that delay electronic switch can not be controlled the load of glow discharge spot lamps such as fluorescent lamp, electricity-saving lamp well that touches, to be exactly that design is a kind of can not only carry out the control of reliable and stable break-make to the load of heat radiation light sources such as ordinary incandescent lamp bubble to purpose of design of the present utility model, and can also carry out reliable and stable break-make control to the load of glow discharge spot lamps such as fluorescent lamp, electricity-saving lamp.

The technical scheme that its technical problem that solves the utility model adopts is: it mainly is the circuit by common touch delay electronic switch, relay and load are formed, the load bulb of the 220 volts of power inputs of civil power that are serially connected with former common touch delay electronic switch circuit is directly received the input that again the coil two ends of relay is concatenated into 220 volts of power supplys of civil power on two left and right sides fixed contacts of relay, and then two moving contacts of relay are directly inserted 220 volts of power supplys of civil power, like this when the controllable silicon in the control circuit of electronic switch satisfies its turn-on condition, controllable silicon is with conducting, in case controllable silicon conducting, the bridge circuit of full-bridge rectification is connected, the coil of relay has electric current to flow through, produce an electromagnetic field, with two moving contacts about relay and about two fixed contacts closed simultaneously, two fixed contacts get about making, thereby load is lighted, and then the control circuit by electronic switch is after the time-delay regular hour, controllable silicon ends, the bridge circuit of full-bridge rectification of the input of 220 volts of power supplys of civil power can't be connected, the coil of relay does not have electric current to flow through, magnetic field diminishes, about relay two moving contacts and about two fixed contacts separate simultaneously, load loses power supply and extinguishes, if the controllable silicon that this moment, general purpose type energy-saving touched in the delay electronic switch circuit satisfies its turn-on condition once more, the bridge circuit of rectification full-bridge is connected once more, the coil of relay has electric current to flow through once more, produce an electromagnetic field, make relay about two moving contacts and two left and right sides fixed contacts closed simultaneously once more, load gets electric work and is lighted, and then by behind the time-delay of the control circuit in the electronic switch certain hour, controllable silicon ends once more, the bridge circuit of full-bridge rectification can't be connected again, the coil of relay does not have electric current to flow through, magnetic field disappears, two left and right moving contacts and two left and right sides fixed contacts of relay are separated simultaneously, load is extinguished, so can carry out reliable and stable break-make control to load repeatedly, this shows, the control circuit of practical touch delay electronic switch is the electric and dead electricity that gets of direct control relay coil, thereby make two left and right moving contacts of relay and two left and right sides fixed contacts closed simultaneously and divide lighting and extinguishing of the control load indirectly of coming, so the control circuit in load and the electronic switch is without any relation, so no matter two fixed contacts of relay are the loads that connects which kind of light source, can not have influence on the work of electronic switch control circuit, this general purpose type energy-saving touches delay electronic switch and possesses simple in structure, utility model, good reliability, energy-conservation, can reduce the power consumption of haveing suffered circuit greatly, thus the useful life of having improved whole electronic switch.

Embodiment

For further setting forth the shortcoming that common touch delay electronic switch can not be controlled the load of glow discharge spot lamps such as fluorescent lamp, electricity-saving lamp, be described further according to Fig. 1 again, in Fig. 1, load bulb (1) is directly to be serially connected with the input that exchanges 220 volts of power supplys, the zero line (21) of 220 volts of AC power of civil power is input to the ac input end of the bridge rectifier of being made up of rectifier diode (3), (4), (5), (6) by the tungsten filament of load incandescent lamp bulb (1), and the live wire of power supply (20) directly arrives the other end of the interchange input of bridge rectifier.This shows, the ac power input end that wants bridge rectifier has stablizes 220 volts of AC power or approximate 220 volts of AC power, the input impedance that must satisfy 220 volts of power inputs of civil power is little, input impedance is more little, the voltage of ac power input end that is input to bridge rectifier is more near 220 volts of voltages of civil power, do not allow too big pressure drop and fluctuation, the DC power supply after the rectification is just stable more, makes its circuit working just reliable.Select thermal radiation light source ordinary incandescent lamp bubble the most suitable so be serially connected with the load (1) of 220 volts of power inputs of civil power, this is because the tungsten filament D.C. resistance in the incandescent lamp bulb (1) is very little, the zero line (21) of 220 volts of power inputs of civil power can be delivered to the ac power input end of full-bridge rectification very smoothly by the tungsten filament in the incandescent lamp bulb (1) like this, pressure drop is very little, can ignore, the live wire (20) that exchanges 220 volts of power supplys this moment is directly inputted to another input of the AC power of full-bridge rectification, the ac input end of full bridge rectifier will obtain a more stable alternating voltage this moment, can be near line voltage, pulsating dc voltage one road after full-bridge rectification is to the anode and the negative electrode of controllable silicon (9), its positive pole connects the anode of controllable silicon (9), negative pole connects the negative electrode of controllable silicon (9), satisfy the controllable silicon turn-on condition, resistance (13) step-down is then passed through on another road, 9.1V voltage stabilizing didoe (7) voltage stabilizing, electric capacity (11) filtering, obtaining a galvanic current presses to integrated package (2) and powers, the course of work of whole so common touch delay electronic switch circuit is: when staff touches metal touch sheet (19), 11 pin of integrated package (2) will be exported high level, reach the control utmost point of controllable silicon (9) by resistance (16), trigger controllable silicon (9) conducting, this moment is by rectifier diode (3), (4), (5), (6) bridge circuit of the full-bridge rectification of Zu Chenging is connected, load incandescent lamp bulb (1) has electric current to flow through, bulb is lighted, 4 pin of integrated package this moment (2) are 0V, silicon speed-sensitive switch diode (8) is partially anti-, electric capacity (12) is delayed time by resistance (15) is discharged behind the certain hour, 8 and 9 pin of integrated package (2) are 0V, 11 pin are low level, controllable silicon (9) ends, the bridge circuit of full bridge rectifier turn-offs, load incandescent lamp bulb (1) does not have electric current to flow through, incandescent lamp bulb (1) extinguishes, the process of whole electronic switch work comes to this and finishes, if human body touched once more and touched sheet (19) this moment, controllable silicon (9) meeting conducting is once more lighted load incandescent lamp bulb (1) once more.If be serially connected in the load of 220 volts of power inputs of civil power is not ordinary incandescent lamp bubble (1), but fluorescent lamp, the load of glow discharge spot lamps such as electricity-saving lamp, the situations such as brownout of rectification full-bridge ac power input end will appear being input to so, thereby cause starting difficulty, the grating flicker, disturb the electrical equipment of periphery to use, might cause false triggering or load not gone out or load still has shimmering phenomenon after extinguishing controllable silicon (9), this is because fluorescent lamp is to cause the tube wall fluorescent material luminous by mercury vapor discharge, needing ballast annexes such as (electric ballast or Inductive ballast and starters) to help start could be luminous, when if load incandescent lamp bulb (1) is fluorescent lamp, just relatively fluorescent tube, electric ballast or Inductive ballast and starter are serially connected with the input of 220 volts of AC power together.Because cause power supply ripple punishment distortion bigger during ballast work, the total harmonic content and the electric current crest that have are also higher, the distortion shape that feeds back to power input is bigger, various reasons such as dc impedance is big cause the entire circuit job insecurity, some unfavorable phenomenons appear, so the load incompatibility of glow discharge spot lamps such as fluorescent lamp, electricity-saving lamp is used on common touch delay electronic switch.

In the embodiment shown in Figure 2, be that the utility model is complete enforcement circuit theory diagrams.Relay (23) be a coil voltage be 220 volts often open double-contact relay, can can select different relays with service condition according to different loads, (22) be the coil of relay (23), (24), (25) two moving contacts about relay (23), directly connect the AC power of 220 volts of civil powers, (26), (27) be two left and right sides fixed contacts of relay (23), directly connect the two ends of free load (28), the coil (22) of its repeat circuit (23) directly is serially connected with the input that exchanges 220 volts of power supplys, the zero line (21) that promptly exchanges 220 volts of power supplys is input to by rectifier diode (3) by the coil (22) of relay (23), (4), (5), (6) ac input end of the bridge rectifier of being formed, 220 volts of power firestreaks of civil power (20), then directly enter the other end that bridge rectifier exchanges input, this moment, the dc output end of bridge rectifier had a stable pulsating dc voltage output, one the tunnel directly is added to the anode and the negative electrode of controllable silicon (9), another road power supply is through resistance (13) step-down, electric capacity (11) filtering is directly inputted to 14 pin positive power source terminals of integrated package (2) after voltage stabilizing didoe (7) voltage stabilizing.The principle of electronic switching circuit control section is the same with circuit control principle shown in Figure 1, it is the load difference that control circuit is controlled, the load that common touch delay electronic switch shown in Figure 1 is controlled is incandescent light bulb (1), the load that general purpose type energy-saving touch delay electronic switch shown in Figure 2 is controlled is the coil (22) of relay (23), the character of two kinds of loads all is the same basically, circuit is worked reliably, but the utility model shown in Figure 2 obviously is better than the electronic switch of common touch time-delay shown in Figure 1.This is that its power is bigger because the load of common touch delay electronic switch control shown in Figure 1 is incandescent lamp bulb (1), is generally tens watts, goes up the power of hectowatt, and circuit power consumption is bigger, and is unfavorable to the useful life of whole electronic switch.Another reason is can only be fit to incandescent lamp bulb is carried out break-make control, has been subjected to placing restrictions in the selection of light source.And its load of being controlled of utility model shown in Figure 2 is the coil (22) of relay (23), its power is very little, the power that generally has only several watts of zero points, power consumption to control circuit is very little very little, can improve the useful life of whole electronic switch comparatively speaking greatly, the employed free load of utility model as shown in Figure 2 (28) is on two left and right sides fixed contacts (26) of directly arriving relay (23), (27) again, so free load (28) is no matter be work and the use not at all influence of the load of which kind of light source to whole electronic switch, work that can both be stable.

Below according to the enforcement schematic diagram of Fig. 2, the whole process of the utility model electronic switch done further again tell about.The live wire (20) of 220 volts of AC power of civil power divides the two-way input, a kind of left moving contact (24) that is input to relay (23), another road is input to by rectifier diode (3), (4), (5), (6) end of the interchange of the bridge rectifier of being formed input, the zero line of 220 volts of power supplys of civil power also divides two tunnel inputs, one the road is directly inputted to the right moving contact (25) of relay (23), another road is then passed through the coil (22) of relay (23) and is delivered to by rectifier diode (3), (4), (5), (6) other end of the interchange of the bridge rectifier of being formed input, because it is very little to be serially connected in the resistance of coil (22) of ac power input end, voltage to the AC power that is input to bridge rectifier does not have great pressure drop, the voltage that still can keep 220 volts of civil powers basically is to the not influence of operating voltage of control circuit.220 volts of anode and negative electrodes that directly are added to controllable silicon (9) by the pulsating dc voltage of exporting behind the bridge rectifier one tunnel of civil power, wherein anode is just connecing, negative electrode connects negative, satisfy its required turn-on condition, another road is through resistance (13) step-down, electric capacity (11) filtering provides stable voltage to supply the power supply of integrated package (2) after voltage stabilizing didoe (7) voltage stabilizing.Touch sheet (19) if catch this moment, because function and effect that integrated package (2) is inner, the control utmost point that makes the trigger voltage of 11 pin output of integrated (2) deliver to controllable silicon (9) through resistance (16) triggers the controllable silicon conducting, and this moment, the bridge circuit of full-bridge rectification was connected.There is electric current to flow through on the coil (22) of relay (23), because the magnetic effect of electric current produces an electromagnetic field, make two left and right moving contacts (24) of relay (23), (25) and two left and right sides fixed contacts (26), (27) closed simultaneously, free load (28) is lighted, after control circuit is delayed time the regular hour, controllable silicon (9) can not be connected by the bridge circuit of full-bridge rectification, the coil (22) of relay (23) does not have electric current to flow through, magnetic field disappears, about two moving contacts (24), (25) with about two fixed contacts (26), (27) separately, free load (28) is extinguished.If touch metal once more and touch sheet (19) this moment, controllable silicon (9) meeting conducting once more, the bridge circuit of full-bridge rectification is connected once more.The coil (22) of relay (23) has electric current to flow through and produces an electromagnetic field, make relay (23) about two moving contacts (24), (25) and two fixed contacts (26), (27) closure, free load (28) is lighted, after control circuit is delayed time the regular hour, controllable silicon (9) ends, the bridge circuit of full-bridge rectification can not be connected, coil (22) no current of relay (23) flows through, magnetic field disappears, two left and right moving contacts (24) of relay (23), (25) and two left and right sides fixed contacts (26), (27) separate free load (28) dead electricity and extinguish, so can be repeatedly carry out reliable break-make control to free load (28), can not influence the control circuit work and the advantages such as interference of electrical equipment to external world again.
