Abstract
The invention belongs to the technical field of electronic products, and particularly provides a rechargeable power adapter. The rechargeable power adapter comprises a shell, a circuit board and an outputting interface, wherein the circuit board is arranged in the shell; the outputting interface is formed in the rear end of the shell; an outputting end of the circuit board is serially connected with the outputting interface; a storage battery is arranged in the shell; an inputting end of the storage battery is connected with the outputting end of the circuit board in parallel; and an outputting end of the storage battery is serially connected with the outputting interface. When small portable electronic equipment or an electronic appliance is powered off and cannot be charged, the rechargeable power adapter can provide for the small portable electronic equipment or the electronic appliance so that the small portable electronic equipment or the electronic appliance can work again, loss and inconvenience which are caused by sudden power lost are avoided, and the rechargeable power adapter brings great convenience to people during working and learning.
Description
Technical field
The invention belongs to technical field of electronic products, be specifically related to a kind of chargeable power supply adaptor.
Background technology
Power supply adaptor is the power supply conversion equipment of small portable electronic device and electronic apparatus, its application is more and more extensive, but current power supply adaptor only plays the effect of combined-voltage conversion, when not having electricity to charge, small portable electronic device and electronic apparatus cannot use, if storage battery can be arranged in power supply adaptor, when small portable electronic device and electronic apparatus cannot charge without electricity, the electricity that can provide by storage battery carries out work, and this will become people's pent-up demand.
Summary of the invention
The object of the invention is to solve existing power supply adapter without the problem cannot charged to electronic equipment or electrical equipment during external power supply.
For reaching above-mentioned purpose, the invention provides a kind of chargeable power supply adaptor, comprise housing, be arranged on the circuit board in housing and be arranged on the output interface of housing rear end, the output of circuit board is connected with output interface, also storage battery is provided with in housing, the output of storage battery input and circuit board is connected in parallel, and accumulator output end and output interface are connected in series.
Above-mentioned housing outer surface installation by adhering has Battery Indicator Light, and Battery Indicator Light and storage battery are connected in series.
Above-mentioned output interface exchanges output interface.
Above-mentioned output interface is direct current output interface, and direct current output interface is USB interface.
Above-mentioned Battery Indicator Light is dichromatic LED.
Advantage of the present invention is: compared with prior art, this chargeable power supply adaptor, comprise housing, be arranged on the circuit board in housing and the output interface being arranged on housing rear end, the output of circuit board is connected with output interface, also storage battery is provided with in housing, the output of storage battery input and circuit board is connected in parallel, accumulator output end and output interface are connected in series, this chargeable power supply adaptor, when small portable electronic device and electronic apparatus cannot be charged without electricity, power supply is provided to make its work, the loss avoiding unexpected power-off to cause and inconvenience, bring great convenience to people's working and learning.
Accompanying drawing explanation
Fig. 1 is the structural representation of chargeable power supply adaptor.
Description of reference numerals: 1, housing; 2, storage battery; 3, output interface; 4, Battery Indicator Light.
Embodiment
Embodiment one
As shown in Figure 1, present embodiments provide a kind of chargeable power supply adaptor, comprise housing 1, be arranged on the circuit board in housing 1 and be arranged on the output interface 3 of housing 1 rear end, the output of circuit board is connected with output interface 3, storage battery 2 is also provided with in housing 1, storage battery input 2 is connected in parallel with the output of circuit board, and storage battery 2 output and output interface 3 are connected in series; Output interface 3 exchanges output interface; Output interface 3 is direct current output interfaces, and direct current output interface is USB interface.
During power supply adaptor external power supply, while powering to portable small-sized portable electric appts and electronic apparatus, accumulators 2 charges, when charging without electricity, portable small-sized portable electric appts and electronic apparatus can utilize the electricity of storage battery 2 to work on, the loss avoiding unexpected power-off to cause and inconvenience, bring great convenience to people's working and learning, output interface exchanges output type and direct-current-output type, the use of USB interface gets more and more, especially mobile phone, major part uses USB data line, meet the electricity consumption requirement of distinct device or electrical equipment.
Embodiment two
Substantially identical with embodiment one, difference is that the housing 1 outer surface installation by adhering in the present embodiment has Battery Indicator Light 4, and Battery Indicator Light 4 and storage battery 2 are connected in series; Battery Indicator Light 4 is dichromatic LEDs.
When storage battery 2 electricity is lower, Battery Indicator Light 4 shows redness, when storage battery 2 is full of, Battery Indicator Light 4 shows green, and user can be reminded to take measures as early as possible, the loss avoiding dead battery to cause or inconvenience, bring great convenience to the working and learning of people.
More than exemplifying is only illustrate of the present invention, does not form the restriction to protection scope of the present invention, everyly all belongs within protection scope of the present invention with the same or analogous design of the present invention.
