Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment:
Embodiment 1: as shown in Figure 1, adopt high-tension electricity magnetic induction, power circuit is used decompression rectifier filter circuit always, and the parameter of electromagnetic induction coil is in the described high-tension electricity magnetic detection circuit: generally be 1000 circles above (1000-4000 circles), and 1000-3000 circle commonly used.Generally be provided with FERRITE CORE in the coil, inductance value is increased.
Amplifier can adopt switch triode or field effect transistor amplifier, and the output of induction coil connects amplifier input terminal, and electric apparatus coil is succeeded in the output of amplifier; The normally opened contact of relay coil is connected on the power input of mains switch socket, therewith the other K switch 1 in parallel of normally opened contact.Diode of series connection and shunt capacitance on above-mentioned induction coil, also parallel diode, also parallel resistance R1 of induction coil in addition.
The TV set high-voltage induction automatic switch that more than constitutes, energized P
1And K switch
1, TV set high-voltage induction automatic switch is placed on is in by the television set of normally watching program state, observe the LED lamp, TV set high-voltage induction automatic switch present position was its suitable place when lamp was bright.Plug with television set and match appliance thereof is inserted in respectively on the socket of high voltage induction automatic switch again, connects K switch
1Can normally open television-viewing.When the user need use a teleswitch disposable shutoff television set and match appliance and TV set high-voltage induction automatic switch, as long as K1 is disconnected, this moment, relay switch JK was in connected state, when the user turns off TV with remote controller, the high-voltage electromagnetic field that produces because of television set disappears, TV set high-voltage induction automatic switch automatic disconnection switch JK realizes the cut-out of television set and match appliance thereof and TV set high-voltage induction automatic switch its own power source.When the user watches TV once more, as long as connect K switch
1, turn on TV with remote controller and can normally watch.
Embodiment 2
As shown in Figure 2, adopt high-tension electricity magnetic induction, on example 1 basis, switch is the electronic type time-delay, its formation: be provided with an amplifier (comprising comparator IC1-2 and switching tube or field effect transistor etc.), amplifier in connects the capacitance resistance delay circuit, and amplifier out is succeeded electric apparatus coil, can be shared with relay on the socket.K switch 1 is chosen as push-button switch.Press start button K switch 1, the circuit energising, IC2 exports electronegative potential immediately, makes the Q3 conducting, relay coil energising adhesive, the LED lamp is bright, the JK closure, and socket is charged, as long as in the delay time of Q3 conducting (as 30-45 second) turn on television set, high-tension electricity magnetic detection circuit of the present utility model detects high-voltage electromagnetic field, makes the Q2 conducting by IC1 output electronegative potential, powers to relay coil simultaneously; IC2 output high potential ends Q3 behind the delay time, owing to Q2 conducting is powered to relay coil, so relay can not disconnect.When the user turns off television set with remote controller, because the high-voltage electromagnetic field that television set produces disappears, the high voltage induction automatic switch is surveyed less than high-voltage electromagnetic field, IC1 exports high potential immediately ends Q2, relay electric-loss disconnects, and JK also disconnects, socket I outage, the plug of (or DVD etc.) is all on same group of socket I, so the power supply of television set and top box of digital machine all is cut off because television set and top box of digital machine.Relay coil also can directly be connected on the output circuit of switching tube.
The employing high-tension electricity magnetic induction way of example 1 and example 2 is suitable for the power supply control of CRT television set, is not suitable for panel TVs such as liquid crystal.
Seek the best placement location of this device during use earlier, make its energy operate as normal.The high voltage induction automatic switch plug is inserted on the attaching plug, presses start button and do not loose one's grip, this moment, the LED lamp was bright, went out about the completely back LED lamp of delay time greatly.Be placed on the TV play side of normally watching with this device and observe the LED lamp this moment, and it is exactly the optimum position that position can make the LED lamp not go out, through after the utility model device just be placed on this position.
Embodiment 3: as shown in Figure 3, adopt the dropping resistor detection mode, at TV set power socket series connection dropping resistor R1, the R1 resistance is: resistance is 0.8-8 ohm, adopts high-power resistance; Especially adopt the step-down sample resistance of 1-3 ohm, as adopting cement resistor etc.
Television set private jack and miscellaneous equipment (as DVD, set-top box etc.) private jack is set.Television set is inserted on its private jack, and during use, energized P1 presses starting switch K1, the circuit energising.Q1 conducting when IC2 exports electronegative potential immediately, the relay adhesive, LED is bright, the JK closure, socket is charged.As long as in the delay time of Q1 conducting (as 30-45 second) turn on television set.Because dropping resistor R1 goes up voltage and uprises, IC1 exports electronegative potential equally, makes Q1 continue conducting, so relay continues closure, socket can not cut off the power supply.When the user shuts down with remote controller, the voltage step-down on the dropping resistor R1, IC1 exports high potential, and Q1 is ended, relay electric-loss, JK disconnects, the supply socket outage.Example 3 adopts the dropping resistor mode, also is applicable to multiple electrical equipment such as panel TV except that the CRT television set.
Use the utility model, the user is as long as press shift knob earlier, and turns on television set with remote controller and can normally watch in delay time, finish watching TV after, cut off the electricity supply simultaneously when shutting down with the remote controller of television set.
