[0035] Figure 1 A schematic structural diagram of a power supply circuit 100 provided in an embodiment of the present application is shown.

[0036] like Figure 1 As shown, an embodiment of the present application provides a power supply circuit 100, including:

[0037] The power module 10 , the conversion module 20 , the switch module 30 and the control module 40 .

[0038] A first output terminal of the power module 10 is connected to a first input terminal of the control module 40 , and a second output terminal of the power module 10 is connected to an input terminal of the conversion module 20 .

[0039] The output terminal of the conversion module 20 is connected to the first input terminal of the switch module 30 .

[0040] The second input terminal of the switch module 30 is connected to the output terminal of the control module 40 , and the output terminal of the switch module 30 is connected to the second input terminal of the control module 40 .

[0041] The control module 40 may be a control chip.

[0042] Specifically, the power module 10 can convert light energy into electrical energy, which is directly transmitted to the control module 40. At the same time, the power module 10 also generates heat energy, which is converted into electrical energy through the conversion module 20, and this part of the electrical energy is transmitted to the control module 40 through the switch module 30.

[0043] In this embodiment, by setting the power module 10, the conversion module 20, the switch module 30 and the control module 40; the first output end of the power module 10 is connected to the first input end of the control module 40, and the second output end is connected to the input end of the conversion module 20; the output end of the conversion module 20 is connected to the first input end of the switch module 30; the second input end of the switch module 30 is connected to the output end of the control module 40, and the output end is connected to the second input end of the control module 40. The power generated by the power module 10 and the power converted by the conversion module 20 are transmitted to the control module 40, so that the control module 40 works without battery power supply, and sustainable green development is achieved.

[0044] Figure 2 A structural schematic diagram of another power supply circuit 100 provided in an embodiment of the present application is shown.

[0045] like Figure 2 As shown, the structure of another power supply circuit 100 provided in the embodiment of the present application is similar to Figure 1The power supply circuit 100 in FIG. 1 is similar in structure, but has some differences.

[0046] The structure and Figure 1 The differences in the structure of the power supply circuit 100 are described in detail.

[0047] In some embodiments, the conversion module 20 includes: a thermocouple conductor 21 and a rectifier 22 .

[0048] An input end of the thermocouple conductor 21 is connected to a second output end of the electric energy module 10 , and an output end of the thermocouple conductor 21 is connected to an input end of the rectifier 22 .

[0049] An output terminal of the rectifier 22 is connected to a first input terminal of the switch module 30 .

[0050] The electrons in the thermocouple conductor 21 are stimulated by the heat energy generated by the power module 10 to move, thereby generating electric energy. The electric energy converted by the thermocouple conductor 21 may be alternating current or direct current. The rectifier 22 can convert the alternating current converted by the thermocouple conductor 21 into direct current, so that the control module 40 obtains the direct current converted by the thermocouple conductor 21.

[0051] In this embodiment, by providing a thermocouple conductor 21 , the heat energy generated by the power module 10 can be utilized to avoid energy waste; and a rectifier 22 is provided to ensure that the electric energy converted by the thermocouple conductor 21 can be utilized by the control module 40 .

[0052] In some embodiments, the power module 10 includes a mechanical flywheel 11 and a photovoltaic panel 12 .

[0053] The mechanical flywheel 11 is electrically connected to the input end of the thermocouple conductor 21 .

[0054] The photovoltaic panel 12 is electrically connected to the first input end of the control module 40 and the input end of the thermocouple conductor 21 .

[0055] The mechanical flywheel 11 rotates to generate heat, which is transmitted to the thermocouple conductor 21, and is converted into electrical energy by the thermocouple conductor 21 and transmitted to the switch module, and then to the control module 40. The mechanical flywheel 11 can rotate with the help of external force.

[0056] The photovoltaic panel 12 converts light energy into electrical energy, which is directly transmitted to the first input terminal of the control module 40. The photovoltaic panel 12 generates heat during operation, which is converted into electrical energy by the thermocouple conductor 21 and transmitted to the switch module, and then to the control module 40.

[0057] In this embodiment, a photovoltaic panel 12 and a mechanical flywheel 11 are provided to realize the conversion of light energy into electrical energy, and the heat generated by the photovoltaic panel 12 during operation and the heat generated by the rotation of the mechanical flywheel 11 are transmitted to the conversion module 20 to realize the conversion of thermal energy into electrical energy, and finally the control module 40 obtains electrical energy without using a battery.

[0058] In some embodiments, the mechanical flywheel 11 is located on the side of the photovoltaic panel 12 away from the light reaction, so as to make use of the space under the photovoltaic panel 12 without affecting the photovoltaic panel 12 to obtain light, thereby avoiding space waste.

[0059] In some embodiments, the photovoltaic panel 12 is circular, the mechanical flywheel 11 is fan-shaped, the radius of the photovoltaic panel 12 is equal to the radius of the mechanical flywheel 11, and the orthographic projection of the center of the photovoltaic panel 12 on the mechanical flywheel 11 overlaps with the center of the mechanical flywheel 11, so as to further save space.

[0060] In this embodiment, the switch module 30 includes a transistor 31 .

[0061] Specifically, the electric energy generated by the photovoltaic panel 12 turns on some functions of the control module 40 , so that the control module 40 can control the transistor 31 to regulate the current, and the electric energy converted by the conversion module 20 is transmitted to the control module 40 through the transistor 31 .

[0062] In some embodiments, a first protection resistor 51 and a second protection resistor 52 are further included.

[0063] The first protection resistor 51 is disposed between the output terminal of the switch module 30 and the second input terminal of the control module 40 .

[0064] The second protection resistor 52 is disposed between the first output terminal of the power module 10 and the first input terminal of the control module 40 .

[0065] By providing the first protection resistor 51 and the second protection resistor 52 , it is prevented that the current transmitted from the power module 10 to the control module 40 and the current converted by the conversion module 20 are too large and break down the control module 40 , so as to protect the control module 40 .

[0066] In some embodiments, an energy storage module 60 is also included.

[0067] The first output terminal of the electric energy module 10 is connected to the first input terminal of the energy storage module 60 , and the second output terminal is connected to the second input terminal of the energy storage module 60 .

[0068] A first output terminal of the energy storage module 60 is connected to a first input terminal of the control module 40 , and a second output terminal of the energy storage module 60 is connected to an input terminal of the conversion module 20 .

[0069] Specifically, the energy storage module 60 can store the electric energy generated by the photovoltaic panel 12 in the electric energy module 10, and the thermal energy generated by the photovoltaic panel 12 and the mechanical flywheel 11. The electric energy generated by the photovoltaic panel 12 is transmitted to the control module 40, and the thermal energy generated by the photovoltaic panel 12 and the mechanical flywheel 11 is transmitted to the conversion module 20. If the electric energy generated by the electric energy module 10 and the electric energy converted by the conversion module 20 are greater than the electric energy required for the control module 40 to work, the electric energy and thermal energy can be stored to avoid energy waste.

[0070] In this embodiment, by setting a thermocouple conductor 21 and a rectifier 22, the heat energy generated by the mechanical flywheel 11 and the photovoltaic panel 12 in the power module 10 is converted into electrical energy to avoid energy waste; a first protection resistor 51 and a second protection resistor 52 are set to prevent the control module 40 from being broken down by a large current; an energy storage module 60 is set, and if the electrical energy generated by the power module 10 and the electrical energy obtained by the conversion module 20 is greater than the electrical energy required for the control module 40 to work, the electrical energy and thermal energy can be stored to avoid energy waste.
