Description of drawings
Fig. 1 is the utility model structural principle schematic diagram.
Embodiment
Be illustrated in figure 1 as the set-top box of a kind of chargeable and external power supply of the utility model, comprise set-top box 10, the mainboard 8 that is provided with switch power module 7 in the set-top box 10 and is connected with the switch power module circuit, switch power module 7 connects 220V power frequency electricity 1 by power line.Also be provided with energy-storage module 2 in the described set-top box 10, energy-storage module 2 is connected with switch power module 7 circuit, and energy-storage module 2 connects 220V power frequency electricity 1 by power line simultaneously.2 parallel connections are connected 220V power frequency electricity 1 by same power line with energy-storage module at switch power module described in the preferred version 7.
As shown in Figure 1, the energy-storage module 2 of preferred structure is made up of the storage battery 3 that connects successively, DC/AC transducer 4, transformer 5, socket 6 and the independent usb interface module 9 that is connected with storage battery 3, wherein socket 6 and usb interface module 9 all have jointing holes, and these jointing holes all are located on the shell wall of set-top box 10.Described switch power module 7 circuit are connected on the storage battery 3 of energy-storage module 2.DC/AC transducer 4 can convert the direct current that storage battery 3 provides to alternating current, carries out transformation by transformer 5 then, makes the voltage that produces satisfy the operating voltage of general household electrical appliances 11, outputs to household electrical appliances 11 such as TV at last by socket 6.
With reference to Fig. 1 the utility model principle be: connect AC220V power frequency electricity 1 with the set-top box plug, the trend of AC220V power frequency electricity 1 has two: one is that 7, one of switch power modules are energy-storage modules 2.Switch power module 7 converts AC220V power frequency electricity can be sent to mainboard 8 for the direct voltage of set-top box operate as normal to, for mainboard 8 work.Energy-storage module 2 makes that by the power frequency electricity electronics shifts in the storage battery 3, produces electrical potential difference, thus store electrical energy.Electrical power storage is full in storage battery 3, and AC220V power frequency electricity is also continual when giving switch power module 7 and energy-storage module 2 power supplies, and energy-storage module 2 will be in resting state.When following situation occurred, energy-storage module 2 startup work: (1) 220V power frequency electricity 1 was stopped power supply; (2) there is external plug to insert on the socket 6 of energy-storage module 2; (3) usb interface module 9 of energy-storage module 2 has circumscribed USB equipment to insert (as mobile phone, MP3 etc.).
