Specific implementation mode
In order that those skilled in the art will better understand the technical solution of the present invention, with reference to embodiment and attached drawing
Product of the present invention is described in further detail.
As shown in figs. 1 to 6, the invention discloses a kind of electric toothbrush wireless charger of low power consumption standby, with with
The electric toothbrush of radio energy receiving circuit matches, and the wireless charger includes that rechargeable energy transmitting coil, height take place frequently
Transmit-receive radio road and micro energy lose control module;The micro energy lose control module includes detection signal collection coil, filter capacitor, rectification two
Pole pipe, current-limiting resistance, bleeder resistor, field-effect tube, cathode and the detection signal collection coil of the rectifier diode are connected in
A bit, the anode of the rectifier diode, filter condenser one end, one end of the bleeder resistor, the source electrode of field-effect tube are total
It is same to be connected in together, the other end of the bleeder resistor, one end of current-limiting resistance, the grid of field-effect tube and the high-frequency emission
The ground terminal of circuit is connected in a bit jointly, the detection other end of signal collection coil, the other end of filter capacitor, current limliting
One end of resistance links together;The grid of the field-effect tube, the other end for the resistance that converges, the other end of current-limiting resistance are common
It is connected together;The drain electrode of the field-effect tube signal output end and is connect in order to control with the control pole of high frequency transmission circuit.
As shown in Figure 5, Figure 6, in the present invention, the signal detection collects the copper on the wiring board that coil is electric toothbrush
Foil carries out circular helical-line formation.The signal detection collects the helix for the circle that coil is made by the copper foil on wiring board
206 replace, and more cost-saving and space also more save technological design.
As shown in figs. 1 to 6, the operation principle of wireless charger of the present invention is:The radio energy receiving circuit is wireless
The radio energy receiving coil 102 of electric toothbrush is connected, high frequency transmission circuit connects wireless charger transmitting coil 103, signal
The collection coil 206 of detection is placed in the bottom of wireless charger transmitting coil 103, and when wireless charger works, working face will
The transmitting of main electromagnetic energy is passed into the object radio energy receiving coil being electrically charged by magnetic field energy collection fasces 101
102.And the signal collection coil 206 of the bottom of transmitting coil 103, it is detected simultaneously by the electromagnetic field of high-frequency emission.And signal is examined
The electromagnetic field detected is converted to electromotive force by the collection coil 206 of survey, by the rectification function of diode 201, to filtered electrical
Container 202 charges, when the electric energy being charged on capacitor 202 is increased to the conducting threshold values of field-effect tube 205, field-effect tube 205
Conducting is relevant to source electrode and drain electrode short circuit, is equivalent to draw and has supported the control of high frequency transmission circuit, high-frequency circuit be stopped into
Enter dormant state, at this time due to still remaining with the electricity stored on filter capacitor, and field-effect tube is maintained to continue to be connected, high-frequency electrical
Road is always maintained at stop working state, only when the electricity on filter condenser 202 passes through bleeder resistor 204 and field-effect tube
The internal resistance of 205 grids runs out of, and the loss of voltage on filter condenser 204, field-effect tube 205 immediately enters Disconnected mode, in
It is that high-frequency circuit is resumed work, repeats the above process, the appropriate capacity for adjusting filter condenser 202, the resistance of bleeder resistor 204
Value, will adjust the time of high-frequency circuit suspend mode and per the time of task, the data in accompanying examples will generate each suspend mode 300ms,
Per task 1ms.The number of turns of adjustment signal detection coil appropriate, enters suspend mode when by the electricity of adjustment charging to which kind of degree
Pattern.
In order to further assess the technique effect of wireless charger of the present invention, further from the power consumption of wireless charger
It generates angle progress principle and data analysis is as follows:
In wireless charger, charger stand-by power consumption is divided to two parts, a part that must be consumed for the working condition of setting
Energy, generally less than 0.1W this is defined herein as P3, and another part is the transmitting coil of wireless charging to spatial emission electromagnetism
The energy consumed when energy, generally accounts for the 90% of total power consumption, is calculated by 1 watt of standby power, is exactly 0.9 watt, this is defined herein as
P4, method here are exactly to work, reach saving energy this 90% part in an intermittent fashion, are in micro energy lose shape
State.
By taking working frequency is the wireless charger of 60KHz as an example, working method is as follows:
Per 300ms, work is primary, every time 3 periods, i.e., only works each second 10 periods,
Therefore the working time is:
T=10/60KHz=0.000167S,
Power consumption is also 0.000167 times originally
Therefore the power P 5 when low power consumption standby is 0.000167 times of P4:
P5=P4*0.000167=0.9*0.000167=0.00015W
Then total stand-by power consumption is:
P01=P3+P4=0.1+0.00015=0.10015W
Only original 0.10015 times, about 10%,
Average stand-by power consumption is as follows:Again for above, after low power consumption standby, the product monthly sold on day cat
It is in the electric power consumed every year:
P11=190,000*0.10015*72=1370052WH=1,370.052kWh
Only original 0.10015 times, about 10%.
Therefore.Wireless charger power savings using the present invention are clearly.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the present invention in any form;It is all
The those of ordinary skill of the industry can be shown in by specification attached drawing and described above and swimmingly implement the present invention;But it is all
Those skilled in the art without departing from the scope of the present invention, using disclosed above technology contents
