The objects, features and advantages of the present invention will be more readily understood by reference to the accompanying drawings and the following detailed description.

1 and 2 show a circuit diagram corresponding to a preferred embodiment of the bobber and the wireless charger in the wireless charging system according to the present invention, respectively.

The wireless charger of Figure 2, the rectifier 70 for converting AC electricity which is a commercial power source of 220V to DC electricity; First and second constant voltage units 90 and 100 for controlling the converted direct current electricity to have voltage values (for example, 30 V and 3 V, respectively) of a predetermined magnitude; A high frequency cut-off unit (80) for cutting a high frequency from the DC electricity; And an oscillation unit 110 for oscillating the high frequency blocked DC electricity into a high frequency signal having a predetermined size (for example, 1 to 1.5 MHz).

In the present embodiment, the detection unit 20 of the bobber is a detection diode (D1), the high frequency removal unit 30 is a second capacitor (C2), the moisture detection unit 50 is a thin and elongate two conductive It is proposed that the water sensing terminal 51 corresponding to the sieve, the light sensing unit 60 being a CDS (cadmium sulfide) cell, and the control unit 120 being the second transistor TR2.

The operation of the embodiment to which the wireless charging system according to the present invention configured as described above is described with reference to FIGS. 1 and 2 as follows.

First, in the rectifying unit 70 provided in the wireless charger of FIG. 2, the third, fourth and fifth capacitors C3, C4 and C5 and the second and third coils L2 and L3 are supplied from a commercial 220V AC electric machine. By-pass and block high frequency components corresponding to noise. Next, the bridge circuit D2 outputs only the alternating current electric current of the positive component among the alternating current electric currents having the (+) and (-) components from which the high frequency components are removed as described above, and the sixth capacitor (C6) is charged. The discharge is repeated to convert the output (+) component alternating current electricity to a direct current electricity by flattening (flat).

In the first constant voltage unit 90, the second resistor R2 receives the converted direct current electric current and supplies a bias current to the base terminal of the third transistor TR3. ZD2 controls to ground only the bias current not exceeding 30V to the base terminal of the third transistor TR3 by grounding when the bias current supplied has a voltage value exceeding 30V. The third transistor TR3 is operated by the bias current supplied as described above, and the direct current electricity converted by the rectifying unit 70 is applied to the second constant voltage unit 100.

In the second constant voltage unit 100, the third resistor R3 supplies the supplied direct current electric current to the third zener diode ZD3 and the third zener diode ZD3 exceeds the 3 V supply current. In case of having a voltage value, only DC current not exceeding 3V is grounded to supply the storage to the high frequency oscillator.

In the high frequency cut-off unit 80, the fourth coil L4 and the seventh capacitor C7 apply electricity to the oscillator 110 having a current having a low frequency determined by the resonance of L4 and C7. The signal is grounded so that it is not applied to the oscillator 110. In addition, the high frequency signals generated by the oscillator 110 are not applied to the front end (rectifier 70, first and second constant voltage units 90 and 100) of the fourth coil L4 and the seventh capacitor C7. It will also play a role in preventing them.

In the oscillator 110, the ninth and tenth capacitors C9 and C10 remove the direct current component among electricity having a low frequency applied from the low pass filter 80, and the fifth coil L5 and the eleventh and The twelfth capacitors C11 and C12 form a closed circuit together with the fourth transistor TR4 so that the low-frequency electricity from which the direct current component is removed is based on the time constant value calculated by the capacitance of L5, C11 and C12 (e.g., For example, oscillation is continuously performed so as to be converted into a high frequency signal having 1 to 1.5 MHz). In this case, the eighth and thirteenth capacitors C8 and C13 and the sixth coil L6 are grounded and removed from the oscillated high frequency signals by exceeding the previously calculated frequencies.

On the other hand, in the tuning section 10 provided in the bobbin of Figure 1, the first coil (L1) and the first condenser (C1) is based on the time constant value calculated by the capacitance of L1 and C1 (the oscillation part of the wireless charger and It is preferable that the frequency is the same and assumes that the frequency is 1 to 1.5 MHz.).

Subsequently, the detection diode D1 detects a high frequency signal, i.e., a DC signal, of the positive component by removing a high frequency signal of the negative component among the tuned high frequency signals, and the second capacitor C2 detects the detected DC signal. The high frequency component corresponding to the middle noise is grounded and removed.

In the overcharge protection unit 40, the first transistor TR1, the first resistor R1, and the first zener diode ZD1 are operated in the same operation principle as the first constant voltage unit 90 in the aforementioned wireless charger of FIG. 2. Therefore, only a DC signal which does not exceed a voltage value corresponding to a specified battery capacity among the DC signals from which the high frequency component has been removed, for example, 2V (when the voltage of the LED operating power supply is 2V and this value may be changed). By being applied to this battery, overcharge to a battery is prevented.

In this way, after the battery is charged with a DC power supply of 2V, when the moisture sensing terminal 51 comes into contact with water (when fishing), electricity is supplied between two terminals of the moisture sensing terminal 51. When the charged DC power is turned on and supplied to the base terminal of the second transistor TR2, and the CDS cell does not detect light (corresponds to night time), electricity is not conducted, so that the moisture sensing terminal ( The DC power supplied by 51 is applied to the LED via the second transistor TR2 in which the switching state is short-circuited and the LED emits light.

On the other hand, when the moisture sensing terminal 51 is not in contact with water (not during fishing), the DC power charged to the emitter terminal of the second transistor TR2 is not supplied. The two transistors TR2 are in an open state, whereby the charged DC power is not applied to the LEDs so that the LEDs do not emit light.

In addition, the moisture sensing terminal 51 is in contact with water, and electricity is conducted between two terminals of the moisture sensing terminal 51 so that the charged DC power is supplied to the base terminal of the second transistor TR2, but the CDS cell In the case where electricity is turned on by sensing the light (this is the case during the day), the DC power supplied to the base terminal of the second transistor TR2 is grounded through the CDS (cadmium sulfide) cell, thereby allowing the second transistor TR2 to be grounded. ) Is open and the LED does not emit light because the charged DC power is not supplied to the LED.

The present invention is not limited to the embodiments described above, and various modifications and changes can be made by those skilled in the art, which are included in the spirit and scope of the present invention as defined in the appended claims.

As described above, the present invention is capable of replacing 500 to 1000 disposable batteries or chemical lights with one rechargeable battery, thereby reducing the amount of environmental pollution and garbage.

In addition, the present invention, by wireless charging the rechargeable battery, in particular in the case of fishing can be a wireless charging of a number of rechargeable batteries at the same time without a contact to reduce the work time as well as to significantly reduce labor costs have.

In addition, the present invention, in particular, by providing both the water sensing means and the light sensing means in the fishing bob, not only can easily determine the position of the fishing bob during the night fishing, but also the light emitting diode provided in the fishing bobber during the day or not fishing By doing so, it saves power.
