Abstract

The utility model relates to a household back-up power supply for supplying power for household network equipment under the power failure state. A 12-V storage battery and a 9-V voltage stabilizing circuit are arranged inside a housing; the 12-V storage battery supplies power for the 9-V voltage stabilizing circuit; and the 9-V voltage stabilizing circuit outputs the power for the household network equipment for power supplying. Therefore, people can still use notebook computers to surf the internet under the power failure state.

Description

A kind of family expenses back-up source

Technical field:

The utility model relates to portable power source, especially a kind of family expenses back-up source.

Background technology:

At present, notebook computer, home network device are very general, meet power failure, and these equipment often can't normally use, though various high-power power failure emergency sets are arranged, power consumption is big, cost is high.

Summary of the invention:

In order to provide a kind of emergency power supply to home network device separately, solve the domestic consumer under power down mode, still can utilize the notebook online, the utility model provides a kind of family expenses back-up source.

The technical solution of the utility model: a kind of family expenses back-up source, it has a housing, enclosure interior is made up of 12V storage battery, 9V voltage stabilizing circuit, the input of 9V voltage stabilizing circuit respectively with the corresponding electrical connection of positive and negative electrode of 12V storage battery, the output of 9V voltage stabilizing circuit extends to outside the housing by connecting line, and connect an output plug endways, also have the charging socket of 12V storage battery at housing.

Beneficial effect: because home network device is 9V direct current supply mostly, the utility model utilizes the 12V storage battery by voltage stabilizing output 9V direct current, under the state that has a power failure, still can utilize the notebook online like this.

Description of drawings:

Below in conjunction with drawings and Examples, the utility model is described in further detail.

Fig. 1 is schematic diagram of the present utility model.

In the drawings, 1.12V storage battery, 2.7809 regulator blocks, 3. charging socket, 4. output plug

Embodiment:

Among Fig. 1, the corresponding electrical connection of input of the positive and negative electrode of 12V storage battery (1) and 7809 regulator blocks (2), the corresponding electrical connection of positive and negative electrode of the input of 7809 regulator blocks (2) and output plug (4), the positive and negative electrode of 12V storage battery (1) also with the corresponding electrical connection of positive and negative electrode of charging socket (3), charging socket (3) is fixed on the housing, and output plug (4) is connected to outside the housing by extended line.

On the basis of Fig. 1, can also set up the 5V voltage stabilizing circuit again, its input connects identical with the electric connection mode of 9V voltage stabilizing circuit, and the positive and negative electrode of output is electrically connected with the positive and negative electrode of a USB socket respectively, this USB socket is fixed on the housing, can be the charging of electronic equipments such as mobile phone.
