Input as 5V direct currents.
Preferably, the main control unit using intelligence system timing detection charging load, by current sense resistor come
Detect electromagnetism output unit overall current, when have charging load close to when ability output current, when load disengage when automatically switch
To power save mode.
Preferably, timed over-currents protection location can be protected to excessively stream.
Preferably, the resonance AC boosting unit carries out boosting processing to voltage.
Preferably, the electromagnetism output unit, which provides the port of wireless charging to electrical equipment and carries out direct current again, becomes friendship
Flow the conversion in magnetic field.
Conventional exchange wireless charging base no-load power consumption reaches 1.5W, the wireless charging of Intelligent Measurement load of the present utility model
The no-load power consumption of electric base is less than 0.3W, compared to very power saving.
Wireless charging base of the present utility model, can detect whether load access, such as no load access with timing automatic
Shi Ze enters power saving resting state, if it is determined that there is load to access, then continues to output charging current, to reach the purpose of power saving,
Due to using USB interface or D/C power as supply input, because USB charger is using widely, so being easily found
Charging source；And inputted using direct current, it is comparatively safe；Wireless charging base of the present utility model, small volume is lightweight, power consumption
It is low.Wireless charging base of the present utility model can be widely applied to electric toothbrush, the charging of the compact electric apparatus such as electric fan.
Brief description of the drawings
Fig. 1 shows schematic diagram of the present utility model.
Fig. 2 shows resonance type wireless live part circuit diagram of the present utility model.

Embodiment
In order that the utility model solve technical problem, use technical scheme, obtain technique effect it can be readily appreciated that
With reference to specific accompanying drawing, embodiment of the present utility model is described further.
With reference to Fig. 1-3, the utility model provides the wireless charging base that a kind of Intelligent Measurement is loaded, including：Direct current is defeated
Enter unit 1, main control unit 2, timed over-currents protection location 3, resonance AC boosting unit 4 and electromagnetism output unit 5.
The continuous input cell uses USB interface or D/C power as supply input, and USB interface or DC inputs are straight for 5V
Stream electricity.
The main control unit 2 uses intelligence system timing detection charging load.
The resonance AC boosting unit 4 can carry out boosting processing to voltage.
The electromagnetism output unit 5 provides the port of wireless charging to electrical equipment, and carries out direct current change AC magnetic field again
Conversion, load access can have been detected whether with timing automatic, such as no load access when if into power saving resting state, if
Judgement has load to access, then charging current is continued to output, to reach the purpose of power saving.
With reference to Fig. 2, each several part in resonance type wireless live part circuit diagram is described as follows：
Boost signal：From main control chip, inputted through PWM ends；
Step-up coil L1：Power output, produces charging magnetic field；
Current loading detects circuit：Current state is read by current sense resistor R3.
With reference to Fig. 3, each several part in software control flow chart is described as follows：
Start：System initialization；
Wireless charging is established by cable：Power output；
Load detecting：Current state is read by current sense resistor；
Automatic calibration：Gating limit value；
Excessively stream：Electric current is excessive to be resetted；
Normal load：Normal band is carried, and electric current exceeds threshold value；
Wireless charging is closed：Power is not exported；
Timer expiry：Timing start-up.
Wireless charging base of the present utility model, can detect whether load access, such as no load access with timing automatic
Shi Ze enters power saving resting state, if it is determined that there is load to access, then continues to output charging current, to reach the purpose of power saving,
Due to using USB interface or D/C power as supply input, and USB charger is filled using widely so being easily found
Power supply；And inputted using direct current, it is comparatively safe；Wireless charging base of the present utility model, small volume is lightweight, low in energy consumption.
