Accompanying drawing explanation
The utility model is further described with reference to the accompanying drawings in conjunction with the embodiments.
Fig. 1 is structural representation of the present utility model.
Embodiment
By describing technology contents of the present utility model, structural feature in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with execution mode.
Refer to shown in Fig. 1, human body infrared induction delay switch, comprise human body infrared inductor, the output of described human body infrared inductor is connected with the base stage of triode Q1, the collector electrode of described triode Q1 and the cathode output end of bridge rectifier pipe D2, one end of electric capacity C1 is connected with the anode of thyristor Q2, the emitter of triode Q1 and the other end of electric capacity C1, one end of resistance R1 is connected with the positive pole of diode D3, the other end of resistance R1 is connected with the positive pole of diode D1, the negative pole of diode D1 is connected with the gate pole of thyristor Q2, the negative electrode of thyristor Q2 is connected with the cathode output end of bridge rectifier pipe D2, one input of bridge rectifier pipe D2 is connected with ac input end, another input of bridge rectifier pipe D2 is connected with the first output, the negative pole of diode D3 and one end of electric capacity C2, one end of resistance R2 connects, the other end of electric capacity C2 is connected with the cathode output end of bridge rectifier pipe D4 and the anode of thyristor Q3, the other end of resistance R2 is connected with the positive pole of diode D5, the negative pole of diode D5 is connected with the gate pole of thyristor Q3, the negative electrode of thyristor Q3 is connected with the cathode output end of bridge rectifier pipe D4, one input of bridge rectifier pipe D4 is connected with ac input end, another input of bridge rectifier pipe D4 is connected with the second output, the capacitance of described electric capacity C2 is greater than electric capacity C1.
Wherein, the utility model is when being connected with electrical appliance, and the first output can receive one end of the first electrical appliance, exchanges the other end that another input can receive the first electrical appliance.The connection of the second electrical appliance is similar with it.
Utility model works principle is as follows: when human body infrared inductor senses human body, human body infrared inductor can export high level, make triode Q1 conducting, alternating current can carry out rectification through bridge rectifier pipe D2, electric current flows through triode Q1, then flow to diode D3, diode D1 and diode D5, finally flow to thyristor Q2 gate pole and thyristor Q3 gate pole, trigger turn on thyristors.After turn on thyristors, be equivalent to negative electrode and the anode of short circuit thyristor, thus electrical appliance two ends also close through the thyristor of bridge rectifier pipe and conducting, and now two electrical appliances normally work.
When human body is just away from human body infrared inductor, human body infrared inductor does not sense human body, human body infrared inductor meeting output low level, triode Q1 is ended, but now electric capacity C1 and electric capacity C2 starts electric discharge, alternating current can through bridge rectifier pipe D2 and bridge rectifier pipe D4 rectification respectively, and electric current flows through triode Q1 and triode Q3, finally flow to thyristor Q2 gate pole and thyristor Q3 gate pole, trigger turn on thyristors.After turn on thyristors, be equivalent to negative electrode and the anode of short circuit thyristor, thus electrical appliance two ends also close through the thyristor of bridge rectifier pipe and conducting, and now electrical appliance also keeps work.After a period of time, first electric capacity C1 discharges and terminates, due to the existence of diode D3, the voltage of electric capacity C2 can not reflux to electric capacity C1, now thyristor Q2 ends, and thyristor Q3 also keeps conducting, the first electrical appliance closedown.Again through after a period of time, C2 discharges end, and thyristor Q3 gate pole does not have trigger current, and thyristor ends, then the second electrical appliance also just can not get electricity and closes.
The utility model in use, can select the size of different electric capacity according to actual conditions, thus can control the time of prolongation.Electric capacity is larger, and time expand is longer.The model of each element can adopt as shown in Figure 1, when alternating current is civil power, the timing of this circuit first output and the second output is tens seconds, and because electric capacity C1 capacitance is less than C2, then the timing of the first output is lower than the second output.To sum up, the utility model uses a human body infrared inductor can realize two-way delays time to control, and save cost, circuit is simple.
The above execution mode, just better embodiment of the present utility model, be not limit the utility model practical range, therefore all equivalences done according to structure, feature and the principle described in the utility model claim change or modify, and all should comprise in the utility model patent claim.
