Embodiment one
The present invention provides a kind of charging units, to solve the above technical problems, with reference to the accompanying drawing to charging unit into
Row detailed description.
Firstly, Fig. 2 shows the schematic block diagrams of charging unit 200 according to an embodiment of the present invention referring to Fig. 2.
As shown in Fig. 2, charging unit 200 according to an embodiment of the present invention includes the switching circuit being arranged in charging unit
210, booster circuit 220 and current detection circuit 230.
According to embodiments of the present invention, wherein charging unit can be used for the charging of various electronic products, for example including but not office
It is limited to smart phone, laptop, intercom, bluetooth headset, Baffle Box of Bluetooth, outdoor monitoring device etc..In following embodiment
In be illustrated by taking bluetooth headset as an example, but it should be noted that for detect other electronic products detection device is similar or phase
Together.
Wherein, by the unlatching of switching circuit and closure, to realize the conducting and disconnection of charging unit.
Optionally, switching circuit is Hall switch circuit, and charging unit is in such a way that Hall switch triggers.Such as when filling
When Denso is set to earphone charging box, charging box 5V booster circuit is opened by Hall switch circuit, is charged to earphone.
Wherein, booster circuit 220, for the voltage of charging unit to be increased to charging voltage after switching circuit is opened
And kept for the first scheduled period.
Certainly, booster circuit 220 is also used to work as within the first scheduled period there is no charging action or in charging complete
Without charging action again in the second scheduled period later, then booster circuit 220 be used for by the voltage drop of charging unit down to
Charging voltage is hereinafter, so that charging unit is in low-power consumption working condition.
Wherein, current detection circuit 230 is used to detect the size of electric current in charging unit, if examining within the first scheduled period
The electric current measured is charging current, then the voltage of charging unit remains charging voltage and charges；If in first expected time of arrival
The interior electric current detected is consistently less than charging current, then the voltage drop of charging unit is down to charging voltage hereinafter, so that charging
Device is in low-power consumption working condition.
Wherein, being less than charging current in the electric current that current detection circuit 230 detects may include following two state:

Through completing to charge, the electric current in charging unit is less than normal charging current at this time；
Second, although switching circuit opens charging unit, and voltage is risen to charging electricity by charging unit
Pressure, but the interface of electronic product to be charged is not electrically connected (i.e. not by electronic product to be charged with the contact of charging unit
Charge), the electric current in charging unit is again smaller than normal charging current at this time.
When there are above-mentioned two situations, for the first situation, charging voltage is kept for the second scheduled period, second
Charging voltage is then kept for the first scheduled period by situation, and the voltage of charging unit is maintained charging voltage by booster circuit, each
From scheduled period in the electric current that detects still less than charging current, then booster circuit is closed, but charging unit can't close,
It can work in a low voltage state, be in low-power consumption working condition.
