Intelligent power socket
First Claim
1. An intelligent power socket, comprising:
- a base, having a casing for covering the top of said base, and said casing at least having a first socket and a second socket, and said first and second sockets being respectively connected to a power supply;
a printed circuit board, being installed at the inner bottom of said base, and further comprising a rectification circuit, and said rectification circuit adjusting an alternate current to a direct current with constant voltage;
a sampling amplify circuit, being coupled to said first socket and said rectification circuit, and converting the alternate current entering said first socket into a direct current;
a compare amplify circuit, being coupled to said sampling amplify circuit and second socket, and comparing the voltage of the current outputted from said sampling amplify circuit with the voltage outputted from said rectification circuit, and outputting a potential signal according to the comparison result;
a control circuit, being coupled to said compare amplify circuit and second socket, and controlling the ON and OFF states of the power of said second socket with respective to the signal inputted from said compare amplify circuit;
by means of foregoing elements, said compare amplify circuit comparing the voltage outputted from said first socket with a standard voltage, and sending a signal to said control circuit, thereby said control circuit turning the power of said second socket on and off with respective to the on and off states of said first socket according to said potential signal, and thus not just saving power, but also disconnecting the power of all sockets without switching off the power of each socket manually.

Abstract
The present invention discloses an intelligent power socket, which comprises a first socket being connected to a second socket by a compare amplify circuit, and the second socket having a control circuit. The compare amplify circuit compares the voltage outputted from the first socket with a standard voltage and outputs a signal to the control circuit, so that the control circuit will follow the instruction given by the signal to turn on or off the power of the second socket as the power of the first socket is turned on or off. The present invention not only reduces the power consumption, but also turns off the power of all sockets automatically, and thus making the operation simple and easy.
