[0014] In some embodiments, the relay coil LK1 and the relay normally open contact LK1-1 belong to a reed current relay, the relay coil LK1 drives the on-off of the relay normally open contact LK1-1 through electromagnetic induction, the size and weight of the reed current relay are greatly reduced, and the service life under normal use is extremely long, which can also effectively improve the practical service life of the circuit.

[0015] According to the technical scheme provided in the application, the diode D1 is a Schottky diode, and the conduction voltage of the Schottky diode is much lower than that of a conventional diode, which can further reduce the energy consumption of the circuit, and on this basis, the switching speed of the Schottky diode is also very fast, and the reverse recovery time can achieve a nanosecond-level response.

[0016] Further, the three-terminal voltage stabilizing block IC1 is an LM117 adjustable positive voltage linear stabilizer, and the LM117 can realize voltage adjustment between 1.25V and 37V, while the voltage of a conventional three-terminal voltage stabilizing block is a fixed value, thereby avoiding frequent replacement of different chips.

[0017] The socket circuit provided in the application has the following specific working principle: First, the live line L and zero line N to 220V mains, the air conditioner power plug connected to the socket Z1, switch power supply circuit U1 output DC 12V voltage into two ways, one way through the type LM117 three-terminal voltage regulator block IC1 3-pin output 3.3V voltage into two ways, one way through the resistance R1 connected to the base of the transistor Q1, Q1 base through the diode D2 and diode D3 in series after again through the negative electrode of diode D3 connected to the 12V power supply negative, so that the Q1 transistor base voltage is limited to about 1V, at this time the transistor Q1 collector is in a low voltage close to 0V state, the other way 3.3V through the Schottky diode D1 forward conduction after output about 3V voltage for the Figure 2 of the super capacitor C3 fast charging, charging time is about 5 seconds; resistance R2 is a red light-emitting diode LED1 current limiting resistor, LED1 is Figure 2 of the super capacitor charging indicator light, when the super capacitor C1 charging, LED1 indicator light will be dark to light, light indicates that the full charge; Figure 2 of the super capacitor C3 air conditioner monitor for internal power supply battery.

[0018] At this time another 12V voltage connected to the positive of the infrared emitter tube UD1, the negative of the infrared emitter tube UD1 is connected to 12V negative through resistance R3, while the 12V voltage is connected to the photoelectric receiving triode UD2 collector, when the photoelectric receiving triode UD2 base receives infrared signal, makes the photoelectric receiving triode UD2 emitter output high voltage through resistance R5 and resistance negative voltage division after connecting to the base of triode Q4, makes triode Q4 turn on, the collector of triode Q4 is connected to the positive of 12V, makes triode Q4 emitter output 12V voltage through resistance R7 connected to the positive of capacitor C1 after charging, while charging through capacitor C1 also through resistance R9 connected to the base of triode Q3, makes triode Q3 turn on, while the emitter of triode Q4 is connected to the emitter of triode Q3 through the negative of diode D6, at this time, triode Q3 is triggered to turn on, the collector of triode Q3 outputs high level through the forward conduction of diode D8, then the negative of diode D8 outputs high level through voltage division of resistance R10 and resistance R11 after connecting to the base of triode Q2, makes triode Q2 saturated conduction, the collector of triode Q2 outputs low level, makes relay coil J1 get electricity work, the normally open contact J1-1 of relay J1 is connected, then makes the socket Z1 get electricity, at this time, the air conditioner power gets electricity, the air conditioner is in standby state, after turning on the air conditioner with the air conditioner remote controller, the air conditioner is in normal working state. When the air conditioner is in normal working state, at this time, the LK1 reed relay coil has 220V voltage through to generate current magnetic field, makes the normally open contact LK1-1 of the reed relay coil LK1 in the LK1 reed relay coil attract and connect, 12V voltage is connected through the normally open contact LK1-1 of relay after charging the capacitor C2 at the same time, the output 12V voltage is connected to the negative of diode D8 through the forward conduction of diode D5, makes triode Q2 keep saturated conduction state, makes relay coil J1 keep working state, makes the air conditioner keep working state.

[0019] At this time when the capacitor C1 is full of electricity after 2 minutes, the triode Q3 is cut off, because the base voltage of the triode Q3 is higher than the emitter voltage by more than 0.7V, so the triode Q3 is in the cut-off state, at this time the collector electrode of the triode Q3 has no 12V voltage output; but because the air conditioner is in the normal start-up working state, the reed relay coil LK1 keeps working, and the air conditioner is in the normal working state. When the remote controller is placed in the remote controller box for charging or storage, at this time the infrared emitter UD1 and the photoelectric receiving triode UD2 are installed on the two sides of the remote controller box. At this time, the remote controller is placed to block the receiving signal of the infrared emitter UD1 and the photoelectric receiving triode UD2, so that the photoelectric receiving triode UD2 cannot receive the infrared signal and is cut off, and the collector electrode of the photoelectric receiving triode UD2 has no high-level signal output. At this time, the triode Q4 is also in the cut-off state. The capacitor C1 will be discharged quickly through the diode D7 forward conduction and the resistor R8 to the ground; soon the capacitor C1 is discharged, so that the triode Q3 is also in the cut-off state all the time.

[0020] At this time, if the air conditioner is turned off, the air conditioner is in the standby state, at this time the current flowing through the reed relay coil LK1 is very small, and the magnetic field generated thereby cannot attract the normally open contact LK1-1 of the relay to be disconnected, at this time the charged voltage on the capacitor C2 is discharged through the diode D5, the resistor R10 and the triode Q2 base to emitter to negative, so that the triode Q2 remains conductive, the relay coil J1 remains in the working state, and the air conditioner remains in the power-on state; after 2 minutes, the charged voltage of the capacitor C2 is discharged, at this time the triode Q2 is cut off, the relay coil J1 loses power and does not work, and the air conditioner is powered off, so as to achieve the air conditioner zero power standby, save electricity and use the super capacitor to power the air conditioner remote controller. The super capacitor has a long service life and is energy-saving and environmentally friendly.

[0021] When the air conditioner is started again, the air conditioner remote controller is taken out of the air conditioner remote controller box, and the air conditioner is powered on.

[0022] The preferred embodiments of the application are described in detail above with reference to the drawings, but the application is not limited thereto. Within the technical concept of the application, various simple modifications can be made to the technical solutions of the application. In order to avoid unnecessary repetition, various possible combinations are not described again. However, these simple modifications and combinations should also be regarded as the disclosed content of the application and belong to the protection scope of the application.
