Summary of the invention:
The purpose of this utility model is to provide a kind of multi-functional mobile phone standby charging device, and it not only can satisfy the user temporarily to the needs of cell-phone charging, and has multi-functional remarkable advantage.
The utility model is to constitute like this, it comprises engine housing and is located at the interior operating circuit of engine housing, it is characterized in that: the output one tunnel of dry battery power is through behind the voltage conversion circuit, form the cell-phone charging power supply, and be connected with the cell-phone charging plug, use in order to the mobile phone power supply, another road output is connected with small-sized electrical appliance.
Operating circuit of the present utility model is formed with small-sized electrical appliance is in parallel by voltage conversion circuit, because the function of voltage conversion circuit not only can make the output end voltage of being made up of dry cell convert the required charging voltage of mobile phone to, and can play the effect of voltage stabilizing direct current, so the electric current of output output is through behind the voltage conversion circuit, will form the 6V direct current, the charging voltage that needs of mobile phone just, be connected with mobile phone by the cell-phone charging plug then, just can charge to mobile phone temporarily.When not carrying out the cell-phone charging use, the electric current of output output at this moment, just can be used as small-sized electrical appliance and uses just through small-sized electrical appliance.
Than existing charging mobile phone battery device, the utility model not only has multi-functional remarkable advantage, and at needs during temporarily to cell-phone charging, only need dry cell combination with provisional configuration, can by voltage conversion circuit conversion form mobile phone the charging voltage of receptible stable state direct current mobile phone is charged, thereby satisfy its needs.
Description of drawings:
Fig. 1 is the circuit theory diagrams of the utility model embodiment.
Fig. 2 is the organigram of the utility model embodiment one.
Fig. 3 is the organigram of the utility model embodiment two.
Embodiment:
With reference to Fig. 1, the utility model embodiment comprises engine housing 1 and is located at the interior operating circuit 2 of engine housing, it is characterized in that: the output one tunnel of dry battery power is through behind the voltage conversion circuit, form the cell-phone charging power supply, and be connected with cell-phone charging plug 3, use in order to the mobile phone power supply, another road output is connected with small-sized electrical appliance.
Above-mentioned voltage conversion circuit is made up of IC-DC conversion series integrated package and peripheral circuit thereof, and above-mentioned small-sized electrical appliance is broadcast receiver or electronic lighter.When not needing to cell-phone charging, this device just can be used as broadcast receiver or electronic lighter has used.
With reference to Fig. 2, above-mentioned engine housing 1 rear portion housing is provided with the cavity 4 that can hold two dry cells side by side, and its head shell is provided with change-over circuit, small-sized electrical appliance and duct 5, cell-phone charging plug 3 grafting location.When small-sized electrical appliance uses as broadcast receiver, be provided with wireless earphone jack 6 and fm dial 7 in the head shell outside of engine housing 1.
When needs are given cell-phone charging temporarily, can buy two dry cells packs in the cavity 4 that holds it, at this moment, this dry cell is as power input, because the operating circuit on the engine housing head shell is formed with small-sized electrical appliance is in parallel by voltage conversion circuit, so the electric current one tunnel of input is through behind the voltage conversion circuit, form the 6V direct current, promptly the cell-phone charging power supply is connected with mobile phone by cell-phone charging plug 3 again, just can charge to mobile phone temporarily, wireless earphone jack 6 when not using as cell-phone charging, inserted with earplug 8 through small-sized electrical appliance in another road, rotate fm dial 7 then and select channel, promptly can be used as broadcast receiver and used.
This apparatus structure is simple, and is easy to manufacture, and cost is low, portably use conveniently, both can be used as broadcast receiver or electronic lighter and used, can form the required charging voltage of mobile phone to the mobile phone use of charging temporarily by change-over circuit with the dry cell combination of provisional configuration again, had the function of a tractor serves several purposes.
With reference to Fig. 3, above-mentioned engine housing 1 comprises outer sleeve body 9 and can be inserted in the interior small electric apparatus body 10 of outer sleeve body, the Plug Division of small electric apparatus body and the internal perisporium of outer sleeve body closely cooperate, can contract to outer sleeve body in the Plug Division that is beneficial to the small electric apparatus body, in its Plug Division, be provided with two dry cells 11 that form small-sized electrical appliance working power, be provided with two dry cells 12 in the outer sleeve body, in small electric apparatus body head shell, be provided with change-over circuit, small-sized electrical appliance and cell-phone charging plug 3 duct 5, location of pegging graft in order to be in series with the small electric apparatus working power.
When small-sized electrical appliance uses as broadcast receiver, be provided with wireless earphone jack 6 and fm dial 7 in the head shell outside of small electric apparatus body.Above-mentioned outer sleeve body internal perisporium is provided with little protruding button 13, and above-mentioned small electric apparatus Plug Division is provided with corresponding small rut 14, and the cooperation in order to as working power the time connects the location.
When mobile phone does not have, when needing interim the charging, release after earlier small electric apparatus body 10 being installed two dry cells, little protruding button 13 on the outer sleeve body internal perisporium connects the location with small rut 14 corresponding matching of small electric apparatus Plug Division at this moment, and then buy two dry cells and pack in the outer sleeve body 9, at this moment, the electric current that is formed by dry cell is as input, because the operating circuit on the engine housing head shell is formed with small-sized electrical appliance is in parallel by voltage conversion circuit, so the electric current one tunnel of input is through behind the voltage conversion circuit, form the 6V direct current, it is the cell-phone charging power supply, be connected with mobile phone by cell-phone charging plug 3, just can charge to mobile phone temporarily, another road is through small-sized electrical appliance, when not using as cell-phone charging, earplug 8 is inserted wireless earphone jack 6, rotate fm dial 7 then and select channel, promptly can be used as broadcast receiver and used.
