When the rotating surface 11 is rotated, the fixed block 12 is fixed with respect to the supporting shaft 14, and the rotating block 13 rotates with respect to the supporting shaft 14.
Further, a magnetoelectric conversion module 20 is disposed between each support shaft 14 and the two corresponding rotating surfaces 11, so that 3 magnetoelectric conversion modules 20 are disposed inside the three-order cube body 10. Each magnetoelectric conversion module 20 includes an N-pole magnetic block 21, an S-pole magnetic block 22, and an induction coil 23, the N-pole magnetic block 21 and the S-pole magnetic block 22 are respectively disposed on the fixed blocks 12 on the two opposite rotating surfaces 11, and at this time, as shown in fig. 1, a magnetic axis is formed between the N-pole magnetic block 21 and the S-pole magnetic block 22, and the magnetic axis coincides with the supporting shaft 14.

The first thermistor Rk is attached to the inner surface of the rotating surface 11 for measuring the actual operating temperature t' of the rotating surface 11. When the resistance of the digital potentiometer Ro is not equal to the resistance of the first thermistor Rk, an electromotive force gradient UAB is formed at the two ends A, B of the wheatstone bridge, where UAB may be positive or negative, and UAB is equal to 0 when the resistance of the digital potentiometer Ro is equal to the resistance of the first thermistor Rk. The temperature control chip is attached to the inner surface of the rotating surface 11 and used for heating the rotating surface 11, the heating mechanism is determined by the UAB value, when the UAB is positive or negative, the temperature control chip heats or refrigerates until the UAB is 0, the actual working temperature of the rotating surface 11 is at the working point of the Ro value of the digital potentiometer set by the processor, and the resistance value of the first thermistor Rk is equal to the resistance value of the Ro of the digital potentiometer.

By utilizing the characteristic, the filter has higher absorption and inhibition capability on overvoltage or spike pulse in a circuit, not only can play a role in overvoltage protection, but also can inhibit interference generated by a switching power supply from being transmitted to a power grid, and plays a dual role in filtering. When the self-locking power supply filtering socket unit 48 is connected with a power line and AN external electric appliance, the microswitch AN is pressed down, alternating current on the power line supplies 12V direct current power to a circuit after being reduced by the capacitor C11 and the capacitor C12, stabilized by the diode D1, rectified by the diode D2 and filtered by the capacitor C2, and is output to the relay J, the coil of the relay J is attracted at the moment, and then acts on the contact J1-1 of the relay J, and the contact J1-1 is switched on to complete self-locking. The alternating current on the power line is output to an external electric appliance through the two-pin socket XS1 and the three-pin socket XS2 after being acted by a power filter consisting of the transformer T and the capacitor C3-the capacitor C6. When a sudden power failure occurs, the contact J1-1 automatically cuts off the main current, so that the impact caused by the fact that the external electrical appliance is not pulled out of the two-pin socket XS1 and the three-pin socket XS2 during the incoming call can be prevented.

When the outer shell of the external electrical appliance leaks electricity, the leakage current forms a loop through the phase line of the triangular socket XS2, the metal shell of the external electrical appliance, the ground line of the triangular socket XS2, the analog sound chip A and the zero line of the power line. The leakage current is limited through a resistor R3 and rectified by a diode VD1, and then the light-emitting diode VD2 is lightened; meanwhile, the leakage current is stabilized through a voltage stabilizing diode VD3, 5V direct current voltage is output from two ends of the leakage current, after the leakage current is filtered by a filter capacitor C, an analog sound generator consisting of an analog sound chip A and a resistor R4 works, and a piezoelectric ceramic piece B sends out an alarm sound to remind a user of timely powering off and maintaining an external electric appliance.
