Abstract

The utility model relates to a power-saving socket, which consists of an alternating current input circuit, a voltage-reducing circuit, a current detecting circuit, an alternating output circuit, and the like. The power-saving socket mainly solves the problem that the existing power-saving socket has complex operation when being applied to computers and peripheral equipment. In order to overcome detects of the prior art, the utility model provides the power-saving socket which can turn on and turn off a power supply automatically. The power-saving socket realizes the automatic power-saving function of the computers and peripheral equipment.

Description

A kind of electricity-saving socket

Technical field

The utility model relates to appliance field, mainly is supply socket and plug converter etc., particularly a kind of electricity-saving socket to computer and the automatic economize on electricity of computer peripheral device.

Background technology

Existing be applied to computer and computer peripheral electricity-saving socket, by detecting computer, when shut down of computer, cut off the electricity supply automatically in the variable power of start during with off-mode; When needs restart computer, need click the subsidiary on ﹠ off switch of electricity-saving socket, make the power supply energising.

The shortcoming of this type of electricity-saving socket is can only cut off the power supply automatically for powering on automatically.

The utility model content

The purpose of this utility model is to provide a kind of electricity-saving socket that can cut off the power supply automatically and power on, mainly solve the technical problem that existing electricity-saving socket product can not power on automatically, in order to overcome the deficiencies in the prior art, the mode that the utility model has adopted a kind of current detecting to combine with sound detection, change outage automatically by detecting electric current, automatically power on by detecting sound, thereby realized automatic outage and the purpose that powers on automatically.

The technical solution of the utility model is:

A kind of electricity-saving socket, in moulding shell, form by reduction voltage circuit, voltage stabilizing circuit, current detection circuit, sound detection circuit, chip intelligent control circuit, button input, relay output control circuit and it is characterized in that sound detection circuit is connected with the chip intelligent control circuit.

Described electricity-saving socket is characterized in that the sound detection circuit front end for being microphone, and the rear end is that sound signal amplifying circuit is formed

Electricity-saving socket described in the utility model can be given the computer and perimeter facility power automatically by detecting sound, and the electricity-saving socket of making can be applicable in the economize on electricity of products such as computer, printer, scanner, copy, thereby reduces the standby energy consumption of this series products.

Embodiment

To help to understand the utility model by the following description of the embodiments, but not limit content of the present utility model.

Accompanying drawing 1 existing electricity-saving socket electrical block diagram;

Among the figure, existing electricity-saving socket is by reduction voltage circuit, voltage stabilizing circuit, current detection circuit, chip intelligent control circuit, and relay output circuit, button inputting circuits are formed; Turn-off by the detected current signal automatic control power supply of current detection circuit; By make relay output by button, power on for external electrical appliance.

Accompanying drawing 2 the utility model electricity-saving socket electrical block diagrams;

Among the figure, reduction voltage circuit adopts resistance-capacitance depressurization or transformer or Switching Power Supply step-down, makes the ac high-voltage of input change low-voltage direct into, by voltage stabilizing circuit pio chip and the needed direct voltage of relay; Current detection circuit is delivered to the chip intelligent control circuit with current changing signal, is turn-offed according to the current signal size control relay of input or is maintained the original state by intelligent chip; When electricity-saving socket is in off-position, i.e. relay output is turn-offed, and as the outside sound is arranged, and the voice signal testing circuit makes the output of intelligent chip control relay with detected voice signal input intelligent chip, powers on for external electrical appliance automatically; Also manual button, control relay output.

Accompanying drawing 3 the utility model voice signal testing circuit schematic diagrams;

Voice signal changes the signal of telecommunication into after receiving by microphone, exports to control chip after amplifying by amplifying circuit, control relay output.
