Abstract
The utility model relates to a can carry out the power adapter who charges to cell -phone isoelectron product under no external power supply's the circumstances. Through the combining of mobile phone power adapter and portable power source, make the user only need carry a product, can satisfy the demand of charging of different occasions. Having under the condition of power, can charge simultaneously to electronic product and built -in battery, also can only select to charge to the electronic product: under the circumstances of non -transformer, the built -in battery of usable adapter charges to the cell -phone.
Description
Technical field
The utility model relates to a kind of can, without external power supply in the situation that, the electronic products such as mobile phone chargingsPower supply adaptor.
Background technology
At present, electronic product is extensive use, and battery electric quantity deficiency is the subject matter that user faces. Although moveMoving power supply can charge to electronic product, but the charging of portable power source is needed to additional adapters. And on present marketPower supply adaptor only can charge in the situation that having power supply, can not meet user's demand.
Utility model content
By the combination of power adapter for mobile phones and portable power source, make user only need carry a product, can expireThe charging demand of the different occasions of foot.
The utility model is mainly solved by following technical proposals for above-mentioned technical problem:
A kind of chargeable power supply adaptor, charging circuit 1, control circuit, charging circuit 2, internal battery, plug 4, pressesThe order of connection of button 1, usb interface 2, usb interface 3 is: plug 4 is connected with charging circuit 1, charging circuit 1 again with control circuitBe connected, control circuit is connected with charging circuit 2 again, and charging circuit 2 is connected with internal battery again, wherein on control circuit, has button1, usb interface 2, usb interface 3.
User discharges and recharges by the button control internal battery on control control circuit.
User selects the electric current of different sizes to charge by two usb interfaces on control circuit.
While having external power supply, both can charge to electronic product by usb interface, can fill internal battery againElectricity.
During without external power supply, can charge by internal battery.
Button 1 on control circuit determines whether charging circuit 2 and internal battery are linked in circuit, thus control rightThe charging and discharging of battery.
The beneficial effects of the utility model are that user only need carry a product, can meet the charging demand of different occasions.
Brief description of the drawings
Accompanying drawing is circuit theory diagrams of the present utility model.
Detailed description of the invention
While having external power supply, input 220V alternating voltage by plug 4, obtain low-voltage DC through overcharge circuit 1,The exportable 1A circuit of usb interface 2, usb interface 3 is exported 2A electric current. User selects whether to input electricity by the button 1 of control circuitFlow to control circuit 2, thereby control the charging to internal battery.
During without external power supply, connect charging circuit 2 and control circuit by the button 1 of control circuit, can at usb interface 2Output 1A circuit, usb interface 3 is exported 2A electric current.
