Abstract

The utility model discloses a power-saving delay-action circuit breaker belonging to an electric appliance control switch. When the user pushes a button, a lamp is turned on, then the lamp can automatic turn off delaying for a plurality of minutes, so the power-saving delay-action circuit breaker can be used for controlling illumination lamps in a toilet, a corridor and stairs. The existing delay-action circuit breaker has a relay-type which adopts mechanical delay and has the disadvantages of high manufacturing cost, short life time, large volume and high noise The existing delay-action circuit breaker has the advantages of long service life, low cost, convenient installation and operation, high reliability, light weight and small size, free delay time adjusting and non power-consuming when a delay circuit doesn't work. The power-saving delay-action circuit adopts the delay circuit composed of electron devices, and the delay circuit can drive loads with different powers when the user exchanges electron devices with different powers.

Description

Power-saving delay-action circuit breaker

The utility model belongs to electric control switch, and lamp is lighted through a few minutes time-delay back light and extinguished automatically when pressing the button.This energy-conservation delay switch be used for lavatory, corridor, stair, etc. the control of place illuminating lamp.Existing delay switch has relay-type, and its principle is: press the follow-up appliance starting of start button, relay is inner to be produced mechanical delay, through turning off power supply automatically after one period time of delay.This switch has several weakness, and cost is higher, and the life-span is short, and volume is big and noise arranged.The ordinary electronic delay circuit needs independent power supply, and delay circuit also consumes a part of electric energy when not working.

The delay circuit that the utility model adopts electronic device to form is an electronic non-contact switch, has overcome above-mentioned defective.The utlity model has long service life, but repeat switch is more than tens0000 times; Cost is low; Consumed power not when delay circuit is not worked, and power supply that need not be independent; Easy to install, only need change original switch to the transformation of original switching system, do not change any other circuit, to not additional any construction cost of the installation of new building and quantities; Reliable, in light weight, volume is little; Function is strong, the load-carrying size of changeable switch when adopting the electronic device of different capacity, additional universal switch can constitute not only the two-way switch of can be kept burning day and night but also can delaying time, also can a lot of lamp of a switch control, and lamp of switch control of a lot of diverse locations; Wide application, this switch also can install neon indicator additional in switch panel or button, this delay circuit can be used for the time-delay of various needs and requires the not really high occasion of delay precision, time of delay to regulate arbitrarily, can solve the problem that altar lamp wastes energy after using this switch.

The main points of this energy-conservation delay switch are that illuminating lamp and energy-conservation delay switch series connection become pulsating direct current through bridge rectifier on the 220V AC power, when pressing hand switch K ₁After, pass through D ₅Give C ₁Charging, when adopting the 10W bulb, the charging interval only needs 0.3 second, so hand can satisfy the requirement in charging interval fully by the habitual movement time of switch.Simultaneously by T ₁R ₁The constant-current source that constitutes is to C ₂Charging.Because the constant-current source electric current is very little, Uc ₂Voltage rises slower, can not reach the controllable silicon trigger voltage, not conducting of controllable silicon at once.Work as Uc ₁Voltage rises to T ₁During puncture voltage, T ₁Puncture (instantaneous breakdown does not damage transistor), at this moment very big electric current is arranged C ₂Charging makes Uc ₂Rise to T rapidly ₂Trigger voltage, T ₂The conducting electric light is bright.Work as T ₂After the conducting, T ₂The negative and positive voltage across poles drop to about 1.4V, make Uc ₁Can not continue to rise.Because diode D ₅Be in the reverse operation state this moment, so C ₁Can not pass through D ₅To T ₂Discharge can only be passed through T ₁, R ₁, R ₂To T ₂Uc is worked as in discharge ₁Drop to T ₁When puncture voltage is following, T ₁With R ₁The constant current that constitutes returns to normal operating conditions.This moment, electric current can make T ₂Continue conducting, from T ₂Conducting begins circuit and just is in the time-delay process.Work as C ₁, C ₂Discharge makes Uc ₁, Uc ₂Drop in the time of can not making the constant-current source operate as normal, constant-current source outputs to T ₂The electric current that control is extremely gone up descends rapidly, thereby can not keep T ₂Continue conducting.At this moment T ₂The shutoff lamp extinguishes, and the time-delay process finishes.

Fig. 1 is the circuit diagram of energy-conservation delay switch.

Fig. 2 is that energy-conservation delay switch and regular tap are connected in series, and finishes the line graph of two kinds of functions.

Fig. 3 is the line graph of a lamp of a plurality of energy-conservation delay switch controls.

Most preferred embodiment of the present utility model is as follows:

Illuminating lamp D among Fig. 1 and the series connection of 220V power supply, D can be at 10～440W with interior any selection, and rectifier bridge is by D ₁, D ₂, D ₃, D ₄Form, all operating currents can both be used K at 1A, reverse breakdown voltage 2 utmost point pipes more than 400V ₁Be push-button switch, requirement can be born 250V, 2A, C ₁Be the withstand voltage 160V of 100 μ F electrochemical capacitors, T ₁Be technotron 3DJ6E, R ₁Be the 100K adjustable resistance, R ₂Be 30K1/8W resistance, C ₂Be 10 μ F25V electrochemical capacitors, C ₂Its UC during operate as normal ₂≤ 1V, T ₂Be trigger current between 10～100 μ A, puncture voltage more than 400V, the one-way SCR of operating current more than 2A.

T ₁R ₁Form constant-current source, to C ₂Constant current charge, its constant current value is by variable resistor R ₁Adjust, work as T ₂Uc after the conducting ₁Through T ₁R ₁The constant-current source constant-current discharge of forming is kept T ₂Continue conducting, both time of delay was by Uc ₁Discharge time decision, this routine delay time is 0.5 minute～10 minutes, D ₅Effect be T ₂Prevent C during conducting ₁Pass through T ₂So the forward current discharge is D ₅In circuit to Uc ₁Charging voltage be reverse connection.R ₂Effect one be the protection T ₂, in order to avoid trigger current is crossed ambassador T ₂Damage, the 2nd, prevent because T ₂Poor quality and make T ₂Produce and do not turn-off phenomenon.

Being connected as shown in Figure 2 of energy-conservation delay switch and regular tap, (1) among Fig. 2 is energy-conservation delay switch, K ₂Be a common cutter two throw switches, two switches are connected in series, and can play two kinds of effects, also can play the control of many lamps list with a plurality of lamps and at the two ends of D.
