Description
Technical field
The utility model belongs to portable power source and in particular to being used for a kind of portable power source of charging bluetooth earphone.
Background technology
In daily life, people run into this situation, when bluetooth earphone is inserted in portable power source charging, fill for a moment
The indicator lamp of portable power source does not just work afterwards, and earphone can fill electricity yet.Why the output voltage of portable power source is also 5V/1A
, and the output of the power supply of family is also 5V/1A, can why portable power source cannot give charging bluetooth earphone.
I see, because general portable power source is with current protection, principle is as it and fills to mobile phone
When electric, mobile phone electricity more and more higher, and the electric current charging will be less and less, when electric current little to certain degree when, just
Mobile phone electricity can be given tacit consent to be full of, disconnect charging and this province of battery capacity of bluetooth earphone is less, electric current during general charging
Less, less than the current protection scope of portable power source, so it is to will be considered that the electricity of earphone is full, would not enter back into and fill
Electricity condition.
Therefore, have producer by the output of portable power source make 5V output normally opened, can to charging bluetooth earphone, but with this with
When, its normally opened boosting when oneself power consumption exist always and larger, battery capacity exhaust quickly and cannot longer-term storage.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of mobile electricity for charging bluetooth earphone
Source.
The technical solution adopted in the utility model is：
For the portable power source of charging bluetooth earphone, including chargeable battery, boost conversion chip, micro USB charging inlet,
USB output port, this chargeable battery is electrically connected with boost conversion chip to carry out the discharge and recharge of battery, and this micro USB charges
Interface is connected to access external power source with the input of boost conversion chip, and the output end of this boost conversion chip is exported with USB
Port connection is charged to bluetooth earphone for exporting electric energy, also includes MCU and the switching switch being connected with this MCU, should
The control end of MCU is connected to control opening and shutting off of boost conversion chip power supply with boost conversion chip, and this switching switchs
For exporting with cut-off signals to MCU.
Further, described portable power source also includes the multiple battery capacity indication lamps being connected with boost conversion chip.
Described battery capacity indication lamp has three and is LED/light source.
Further, described portable power source also includes the relay indicating light being connected with MCU.
Wherein, described boost conversion chip is IP5305 chip.
The beneficial effects of the utility model：
The utility model portable power source scheme controls unlatching and the pass of boost conversion chip power supply by the MCU of a very little
Disconnected.When MCU opens the power supply of boost conversion chip, solve bluetooth earphone when charging current is less than 30mA, portable power source
The problem of charging bluetooth earphone can not be given；When MCU turns off boost conversion chip power supply, the shutdown power consumption of portable power source is smaller than
9uA, thus solve the problems, such as that low capacity portable power source is unable to long term storage.
Brief description
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described further.
Fig. 1 is the theory diagram of the utility model portable power source.
Specific embodiment
With reference to shown in Fig. 1, be the portable power source for charging bluetooth earphone of the present utility model, including chargeable battery 10,
Boost conversion chip 20, micro USB charging inlet 30, USB output port 40, this chargeable battery 10 and boost conversion chip 20 electricity
Property connect to carry out the discharge and recharge of chargeable battery 10, the input of this micro USB charging inlet 30 and boost conversion chip 20 is even
Connect to access external power source, the output end of this boost conversion chip 20 be connected with USB output port 40 for export electric energy to
Bluetooth earphone is charged；
On the basis of above-mentioned conventional structure, the technical program is additionally arranged MCU50 and the switching switch being connected with this MCU50
The control end of 60, this MCU50 is connected with boost conversion chip 20 to control opening and shutting off of boost conversion chip 20 power supply,
This switching switch 60 is used for exporting with cut-off signals to MCU50.
During use, by once switching switch 60, MCU50 output control signal is to boost conversion chip 20, boost conversion core
Piece 20 starts work of boosting, when USB output port 40 accesses the USB line connecting bluetooth earphone, just can be by chargeable battery 10
Electric energy boosting after bluetooth earphone is charged；Once switch switch 60 when user presses again, just can make boost conversion chip
20 stop boosting work, cut-out output.
As the supplement of the technical program, described portable power source also includes the multiple electricity being connected with boost conversion chip 20
Indicator lamp 70, battery capacity indication lamp 70 has three and is LED/light source.
As another supplement of the technical program, described portable power source also includes the relay indicating light 80 being connected with MCU50,
In order to remind voltage ascending conversion chip 20 in working order, go in time to turn off thus avoiding portable power source own loss, and this
The shutdown loss of technical scheme is minimum, is smaller than 9uA, so that portable power source can long-time storage.
Wherein, described boost conversion chip 20 is IP5305 chip.As the supplement of the technical program, described boost conversion
Chip can also be boosting, charge two-in-one chip, or boosting, charge, electricity shows three-in-one chip, or even integrated more
The All-in-One chip of function.
As described above, the utility model portable power source scheme controls boost conversion chip power supply by the MCU of a very little
Be switched on and off.When MCU opens the power supply of boost conversion chip, solve bluetooth earphone and be less than 30mA in charging current
When, portable power source can not give the problem of charging bluetooth earphone；When MCU turns off boost conversion chip power supply, the pass of portable power source
Machine power consumption is smaller than 9uA, thus solving the problems, such as that low capacity portable power source is unable to long term storage.
The foregoing is only preferred embodiments of the present utility model, the utility model is not limited to above-mentioned embodiment party
Formula, if the technical scheme realizing the utility model purpose with essentially identical means broadly fall into protection domain of the present utility model it
Interior.
