1 and 2, the wireless power supply method includes steps S1 to S7.

In step S1, the first control unit 11 transfers a preset power from the rechargeable battery 91 to the second control unit 21 through the first coil unit 12 and the second coil unit 22, In order to provide the power required for the operation of the second control unit 21 and the sensing unit 23. In more detail, the user turns on the waterproof power supply device 100 through the input unit 13, so that the waterproof power device 200 obtains the preset power, for example, the preset power is sufficient to provide the second control unit 21 And the sensing unit 23 operates.

In step S2, a critical threshold and an identification code corresponding to the load unit 92 are pre-stored by the second control unit 21, and the critical threshold and the identification code are passed through the second coil unit 22 and the first coil The unit 12 is transmitted to the first control unit 11. For example, in the existing wireless charging technology, the transmitter 1 uses Frequency-Shift Keying (FSK) technology to transmit signals to the receiver 2, and the receiver 2 uses amplitude offset Amplitude-Shift Keying (ASK) technology transmits the signal to the transmitter 1. In addition, the critical threshold and the identification code can also be stored in a storage unit in advance, and then read by the second control unit 21. The storage unit is, for example, a non-volatile memory, but not Is limited.

In step S3, the load cell 92 is detected by the sensing unit 23 to obtain a state value corresponding to the operating state of the load cell 92. In this embodiment, the The state value is a set of temperature values and includes the at least one detected temperature.

In step S4, the state value is transmitted to the first control unit 11 via the second coil unit 22 and the first coil unit 12 by the second control unit 21.

In step S5, according to the state value and an input signal from the input unit 13, the first control unit 11 transfers an output power from the rechargeable battery 91 through the first coil unit 12 and the second coil The unit 22 transmits to the second control unit 21 and controls the output power. In addition, the first control unit 11 transmits the input signal to the second control unit 21 after adjusting the output power. For example, in this embodiment, the input unit 13 is a button, and when the button is pressed by the user, the input signal is generated. In addition, it should be supplemented that the first control unit 11 controls the change of the output power, which is also included under the same power level, and controls the change of the voltage corresponding to the output power.

In more detail, the first control unit 11 also pre-stores a look-up table, the look-up table includes a plurality of different identification codes, and a corresponding relationship of a plurality of power values corresponding to each of the identification codes. For example, the look-up table contains five identification codes to correspond to five different load units 92. One of the identification codes corresponds to four sets of power values, and the remaining four identification codes also correspond to multiple power values. Is limited.

When the first control unit 11 determines that the state value is greater than the critical threshold When, control the size of the output power to become smaller. In this embodiment, that is, when any one of the at least one detected temperature is greater than the critical threshold, there is a risk of causing the user to be scalded by the load unit (ie, the waterproof heating cloth) 92. Therefore, the control The output power received by the load unit 92 via the second control unit 21 becomes smaller, thereby reducing the state value.

When the first control unit 11 determines that the state value is less than the critical threshold value, it selects one of the power values corresponding to the identification code according to the input signal, and controls the output power to be equal to the one of the power values. . In this embodiment, for example, the identification code corresponds to four sets of power values, which are 100W, 150W, 200W, and 250W in order. Each time the input unit (ie, the button) 13 generates an input signal, the first control unit 11 selects the four power values in turn, for example, from 100W to 150W, then to 200W, then to 250W, and then It is 200W and then converted to 150W to control the output power.

In step S6, after the second control unit 21 receives the input signal from the first control unit 11 (as in step S5), the magnitude of the output power received through the second coil unit 22 is detected , And generate a corresponding confirmation signal, and transmit the confirmation signal to the first control unit 11 via the second coil unit 22 and the first coil unit 12.

In step S7, the first control unit 11 controls the output unit 14 to output a display signal according to the confirmation signal to instruct the second control unit 21 to detect Measure the size of the output power, or display the value of the output power. Then, step S3 is executed again. The output unit 14 is at least one of a vibration device, an acoustic device, and a display device, and the display signal is corresponding to at least one of a vibration message, an acoustic message, and a display message . For example, in this embodiment, the output unit 14 is the vibration device, and the vibration message includes one short vibration, two short vibrations, three short vibrations, and four short vibrations. Continue the previous example, and correspond to the power values respectively equal to 100W, 150W, 200W, and 250W. That is, each time the receiver 2 receives and detects the updated output power, it informs the user of the output power through the display signal.

In addition, it should be specifically supplemented that: in the first embodiment, the waterproof power supply device 100 can obtain the corresponding relationship of the waterproof power device 200 by, for example, the identification code. Therefore, the output power adjusted by the first control unit 11 according to the input signal can be designed and arranged in advance so that the output power received by the second control unit 21 via the second coil unit 22 The size meets the predetermined goal. That is, the magnitude of the output power received by the waterproof electrical device 200 indicated by the confirmation signal will be equal to the magnitude of the output power selected by the input unit.

In other embodiments, in step S6, the first control unit 11 also controls the output power according to the confirmation signal, so that the second control unit 21 detects that the second coil unit 22 The magnitude of the received output power is equal to the magnitude of one of the power values corresponding to the identification code. In other words That is, in step S5, the first control unit 11 first controls the output power according to the input signal, and then, in step S6, the first control unit 11 controls the output power according to the confirmation signal. , So that the power actually received by the second control unit 21 meets the power value or the target size corresponding to the power option. In this way, even if the waterproof electric device 200 and the waterproof power supply device 100 are not in a one-to-one relationship designed in advance, the waterproof power supply device 100 can achieve a predetermined power output through this feedback and confirmation mechanism. .

1 and FIG. 3, FIG. 3 is a second embodiment of the wireless power supply method, which is substantially the same as the first embodiment, and the difference lies in steps S2 and S5.

In step S2, the second control unit 21 pre-stores the critical threshold and multiple power options corresponding to the load unit 92, and passes the critical threshold and the power options through the second coil unit 22 and the first A coil unit 12 is transmitted to the first control unit 11. For example, there are three power options, which are the first stage, the second stage, and the third stage.

In step S5, according to the state value and the input signal from the input unit 13 by the first control unit 11, the output power is transmitted from the rechargeable battery 91 through the first coil unit 12 and the second coil The unit 22 transmits to the second control unit 21 and controls the output power. For example, in this embodiment, the input unit 13 is also a button, and when the button is pressed by the user, the input signal is generated.

When the first control unit 11 determines that the state value is greater than the critical threshold, the output power is controlled to decrease. When the first control unit 11 determines that the state value is less than the critical threshold, it selects one of the power options according to the input signal, and controls the output power to be equal to a predetermined power value corresponding to that one. . For example, in this embodiment, the first control unit 11 also stores another look-up table, and the other look-up table stores the predetermined power values corresponding to the first segment to the third segment being 200W and 300W, respectively. , And 400W. Each time the input unit (ie, the button) 13 generates an input signal, the first control unit 11 alternately selects the predetermined power value corresponding to the three power options, for example, 200W is converted to 300W, then converted to 400W, and then Turn it to 300W, then to 200W, and then to 300W to control the output power.

In addition, in other embodiments, the power options pre-stored by the second control unit 21 may also be the predetermined power values directly, that is, the second control unit 21 directly stores the other look-up table (then the The first control unit 11 does not store), so that the first control unit 11 controls the output power accordingly.

In addition, in the second embodiment, the waterproof power supply device 100 and the waterproof power consumption device 200 have a pre-designed one-to-one relationship. Therefore, the output power adjusted by the first control unit 11 according to the input signal can be designed and arranged in advance so that the output power received by the second control unit 21 via the second coil unit 22 The size meets the predetermined goal.

In other embodiments, in step S6, the first control unit 11 also controls the output power according to the confirmation signal, so that the second control unit 21 detects that the second coil unit 22 The received output power is equal to the numerical value of one of the power options. In other words, in step S5, the first control unit 11 first controls the output power according to the input signal, and then, in step S6, the first control unit 11 controls the output power according to the confirmation signal. The size of, so that the power actually received by the second control unit 21 meets the power value or the target size corresponding to the power option. In this way, even if the waterproof electric device 200 does not have the corresponding identification code, the waterproof power supply device 100 can achieve a predetermined power output through this feedback and confirmation mechanism.

To sum up, the waterproof power supply equipment and the waterproof electrical equipment do not need to use the connector structure design of the connection line such as the conventional technology, so that it can be used in various water sports, medical environments, mountaineering or other wet conditions. By implementing the wireless power supply method, the power required for the operation of various load units can be safely provided, so the purpose of the invention can be achieved.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited by this, all simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the content of the patent specification still belong to Within the scope covered by the patent of the present invention.
