Embodiment 1

[0018] A socket for a power-saving electrical appliance in this embodiment includes a casing, an intelligent control circuit connected to the mains in the casing, and a socket connected to the intelligent control circuit. The intelligent control circuit includes sequentially connected AC input terminal, relay, transformer, rectifier circuit, first switching tube (VT1), adjustable power supply, second switching tube (VT2) and output terminal, the AC input terminal is used to connect to the mains, and the output terminal is used When the load is connected through the socket and the load is working normally, the second switching tube (VT2) and the first switching tube (VT1) are saturated and turned on, the relay (K1) works normally, and the normally open contact is closed to ensure that the power circuit is normal Power supply; at the same time, the first capacitor (C2) is charged through the second switch tube (VT2), when the current at the load terminal is less than a threshold ...

Embodiment 2

[0022] See attached figure 1, the power-saving appliance socket includes two AC input terminals, the first AC input terminal is connected to one end of the relay K1, the other end of the relay K1 is connected to one end of the primary winding of the transformer T1, and the two ends of the relay K1 are connected in parallel with a control switch S1, The manner of controlling the on-off of the switch S1 is a familiar manner in the art, and will not be repeated here. The other end of the primary winding of the transformer is connected to the second AC input end, the secondary side of the transformer T1 is rectified by the rectifier circuit, the two ends of the rectifier circuit are connected in parallel with the capacitor C1, the positive pole of the capacitor C1 is connected to one end of the LED1 lamp, and the other end of the LED1 lamp is connected to One end of resistor R1, the other end of resistor R1 is connected to the cathode of capacitor C1, the cathode of diode VD3 is c...

Abstract

The invention discloses a power-saving electrical appliance socket, comprising a shell, an intelligent control circuit connected to a mains supply, and a socket connected to the intelligent control circuit, wherein the intelligent control circuit and the socket are arranged in the shell, the intelligent control circuit comprises an alternating current input end, a relay, a transformer, a rectifiercircuit, a first switching tube (VT1), an adjustable power supply, a second switching tube (VT2) and an output end that are sequentially connected, when the current of a load end is less than a threshold current, a third capacitor (C4) is slowly charged, the voltage at both ends of the third capacitor (C4) rises slowly, and after a first delay time, the voltage at both ends of the third capacitor(C4) rises to a certain extent, the second switching tube (VT2) is cut off, and due to the discharge of a first capacitor (C2), the first switching tube (VT1) continues to keep a conducted state, andafter a second delay time, the first switching tube VT1 is cut off, the relay K1 is disconnected to cut off the entire power circuit, and thus the power supply can be automatically and completely shut off under a small current state of the load end.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a power-saving appliance socket which can automatically cut off the power supply in the case of standby and other currents. Background technique [0002] In the prior art, many electrical appliances can be turned off by remote control to enter a low current state such as standby state, but in real life, if you want to completely turn off the power supply, you need to manually turn off the switch of the electrical equipment, for example, when watching TV to After late at night, users lying in bed do not want to get up to turn off the power of the TV, but choose to use the remote control to turn it off to standby, but for many users, they still want to be able to completely turn off their power connection, on the one hand, for To save electricity, some are also for safety considerations. In addition, there are technologies in the prior art that can automatically shut off th...
