Abstract

The utility model discloses a kind of interchange and input 110V-220V automatic switching function control circuit, comprise input service voltage module, voltage stabilizing circuit module, control circuit module, automatic switch-over circuit module, can be arranged on different electric upper uses this system as required.The utility model makes electric appliance and electronic product wide model in the different civil power in countries in the world use, and does not worry because the different line voltage in various countries makes electronic apparatus produce the phenomenon that can not work or blast, thus facilitates consumer to use electric appliance and electronic product.

Description

A kind of interchange inputs 110V-220V automatic switching function control circuit

Technical field

The utility model is applied to electronic control circuit, is especially applied in and has in the electronic control circuit of automatic switching function.

Background technology

Exchanging input 110V-220V automatic switchover system is widely used on different electronic apparatus, a lot of electric equipment products is all import and export at present, and from country variant and area, and the line voltage of each country is different, some operating voltage 110V, some operating voltage 220V.Often a lot of electric equipment products does not install input voltage automatic switching function system, but on electronic apparatus, a switch is installed, to manually select, like this to pin expense person with many inconvenience, if it is consistent with civil power to forget the good electric equipment products input voltage of the person of choosing, the safety of electronic product and reliability can be caused to reduce greatly, also on some electric equipment products, optional input voltage switch is not all installed, make the sales region of product not extensive like this, can only at fixing field sales.

Summary of the invention

The purpose of this utility model is, in order to overcome the shortcomings and deficiencies of prior art, provides a kind of structure simply can according to the numerical value automatic switching control circuit of 110V-220V alternating voltage of input.

The purpose of this utility model can reach by taking following technical scheme:

A kind of 110V-220V automatic switching function control circuit, operating voltage input module, voltage stabilizing circuit module, control circuit module, automatic switch-over circuit module, described work input voltage comprises extraneous input 110V or 220, described voltage stabilizing circuit module, include the disparate modules in integrated voltage-stabilized system, voltage-stabilizing system is made surely to go out a reference voltage more accurately like this, to control circuit module accurately reference voltage go to control automatic switch-over circuit module, the input that recognizes allowing automatic switch-over circuit module zero slip up switches to the civil power consistent with input voltage.

As the more preferred embodiment of the utility model patent, the input that recognizes of described automatic switch-over circuit module zero error switches to the civil power made with input voltage one.Because the input of operating voltage input module and the power supply input of electric equipment products link together, and after 110V-220V automatic switching function system modules, then to each system in electric equipment products.

Compared with prior art, the utility model has the following advantages:

One, existing electric equipment products is manual operation, is fixing input voltage in addition, and electric equipment products is installed this system on product, and facilitate pin expense person to use, the scope of sale also considerably increases.

Two and the cost of this system is low, volume is few, separately need not reserve installation position to this system when product increases this system, installs the outward appearance that this system also can not change product, easy for installation.

accompanying drawing illustrates:

Fig. 1 is the utility model patent frame principle figure;

Fig. 2 is the utility model circuit structure schematic diagram.

specific implementation method:

below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.

As described in Figure 1, one of the present utility model exchanges input 110V-220V automatic switching function control circuit and comprises operating voltage input module 1, voltage stabilizing circuit module 2, control circuit module 3, automatic switch-over circuit module 4, operating voltage input module 1 provides voltage stabilizing circuit module 2 operating voltage, burning voltage module 2 stablizes a reference voltage to control circuit module 3, and control circuit module 3 sends different signal controlling interchange input 110V-220V automatic switch-over circuit modules 4 and automatically switches.

As described in Figure 2, one of the present utility model exchanges input 110V-220V automatic switching function system and comprises AC and be input to D1 to R1 and R3 and be divided to V1 and work, ZD1 and ZD2 is stable there emerged a reference voltage 37V through C1, C2 R4 obtains more precisely more stable reference voltage after forming a RC filtering, to the conducting of the nonpolarity two pole control Q 2 of D2 and cut-off, identified the switch operating of input voltage by Q2.

Above-described the utility model execution mode, does not form the restriction to the utility model protection range.Any do within spirit of the present utility model and principle amendment, equivalent to replace and improvement etc., all should be included within claims of the present utility model.
