Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical solution of the utility model, below in conjunction with embodiment and accompanying drawing, this utility model product is described in further detail.
As shown in figs. 1 to 6, the utility model discloses the electric toothbrush wireless charger of a kind of low power consumption standby, with and there is radio energy receive the electric toothbrush of circuit and support the use, described wireless charger includes rechargeable energy transmitting coil, high frequency transmission circuit and Micro Energy Lose control module；Described Micro Energy Lose controls module and includes detection signal collection coil, filter capacitor, commutation diode, current-limiting resistance, bleeder resistor, field effect transistor, the negative pole of described commutation diode is connected in a bit with detection signal collection coil, the positive pole of described commutation diode, filter capacitor one end, one end of described bleeder resistor, the source electrode of field effect transistor is connected in together jointly, the other end of described bleeder resistor, one end of current-limiting resistance, the grid of field effect transistor and the earth terminal of described high frequency transmission circuit are connected in a bit jointly, the other end of described detection signal collection coil, the other end of filter capacitor, one end of current-limiting resistance links together；The grid of described field effect transistor, the other end of the resistance that confluxes, current-limiting resistance the other end be jointly connected together；The drain electrode of described field effect transistor is for control signal outfan and is connected with the control pole of high frequency transmission circuit.
As shown in Figure 5, Figure 6, in this utility model, it is that the Copper Foil on the wiring board of electric toothbrush carries out circular helical-line formation that described signal detection collects coil.Described signal detection is collected the helix 206 of the circle that coil is made by the Copper Foil on wiring board and is replaced, and technological design is also more economized in more cost-saving and space.
As shown in figs. 1 to 6, the operation principle of wireless charger described in the utility model is: this radio energy receives the radio energy receiving coil 102 of circuit wireless connections electric toothbrush, high frequency transmission circuit connects wireless charger transmitting coil 103, the coil 206 of collecting of signal detection is placed in the bottom of wireless charger transmitting coil 103, when wireless charger works, main electromagnetic energy transmitting will be passed to the object radio energy receiving coil 102 being electrically charged by magnetic field energy boundling rod 101 by work surface.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.nullAnd the electromagnetic field detected is converted to electromotive force by the coil 206 of collecting of signal detection，Rectification function by diode 201，Charge to filter capacitor 202，When the electric energy being charged on capacitor 202 is increased to the conducting threshold values of field effect transistor 205，Field effect transistor 205 turns on，It is relevant to source electrode and drain short circuit，Be equivalent to draw the control to high frequency transmission circuit，High-frequency circuit quits work entrance resting state，Now owing to filter capacitor still remaining with the electricity stored，And maintain field effect transistor continuation conducting，High-frequency circuit is always maintained at the state of quitting work，Only when the electricity on filter capacitor 202 is run out of by the internal resistance of bleeder resistor 204 and field effect transistor 205 grid，Loss of voltage on filter capacitor 204，Field effect transistor 205 immediately enters Disconnected mode，Then high-frequency circuit is resumed work，Repeat said process，Suitably adjust the capacity of filter capacitor 202，The resistance of bleeder resistor 204，Time by the time of adjustment high-frequency circuit dormancy and every task，Data in accompanying examples，Each dormancy 300ms will be produced,Every task 1ms.The number of turn of suitable adjustments signal detection coil, by entrance park mode when adjusting the electricity of charging to which kind of degree.
In order to assess the technique effect of wireless charger described in the utility model further, carry out principle from the power consumption generation angle of wireless charger further and data analysis be as follows:
In wireless charger, charger stand-by power consumption divides two parts, and a part is the energy that the duty set must consume, being generally less than 0.1W, be defined herein as P3, another part is the energy that the transmitting coil of wireless charging consumes when to spatial emission electromagnetic energy, generally account for the 90% of total power consumption, calculate by 1 watt of standby power, it is simply that 0.9 watt, it is defined herein as P4, here method, it is simply that by this part of 90%, work in an intermittent fashion, reach to save energy, be in Micro Energy Lose state.
The wireless charger being 60KHz for operating frequency, working method is as follows:
Every 300ms works once, in each 3 cycles, namely only works each second in 10 cycles,
Therefore the working time is:
T=10/60KHz=0.000167S,
Power consumption is also original 0.000167 times
Therefore the power P 5 during 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, and after adopting low power consumption standby, the product monthly sold on sky cat at the annual electric power consumed is:
P11=190,000*0.10015*72=1370052WH=1,370.052kWh
Only original 0.10015 times, about 10%.
Therefore.Adopt wireless charger power savings of the present utility model clearly.
The above, be only preferred embodiment of the present utility model, and this utility model is not done any pro forma restriction；The those of ordinary skill of all industry all can shown in by specification accompanying drawing and the above and implement this utility model swimmingly；But, all those skilled in the art without departing within the scope of technical solutions of the utility model, available disclosed above technology contents and make a little change, modify and the equivalent variations of differentiation, be Equivalent embodiments of the present utility model；Meanwhile, the change of all any equivalent variations above example made according to substantial technological of the present utility model, modification and differentiation etc., all still fall within the protection domain of the technical solution of the utility model.
