[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0027] Reference Figure 1-6 As shown, a double-layer capacitor includes a pin 1, a main body 2 is fixedly installed at the lower end of the pin 1, the pin 1 is symmetrically arranged about the axis of the main body 2, an adjusting device 3 is provided in the main body 2, and the staff can adjust the discharge amount of the capacitor through the adjusting device 3 according to needs, and a rotating groove 8 is provided on the outer surface of the main body 2, and the adjusting device 3 is rotatably connected to the main body 2 through the rotating groove 8.

[0028] like Figure 2-3 As shown, the adjusting device 3 includes a rotating plate 4. Since the height of the rotating groove 8 is consistent with the thickness of the rotating plate 4, after rotation, the rotating plate 4 will not deviate or shake due to the friction force. A plurality of connecting plates 5 are installed corresponding to the upper surface and the bottom surface of the rotating plate 4. The pin 1 passes through the upper surface of the main body 2 and abuts against the connecting plate 5 on the upper surface of the rotating plate 4. A plurality of fixing grooves 6 are opened in the rotating plate 4 corresponding to the connecting plate 5. A resistor 7 is fixedly installed inside each of the fixing grooves 6. The resistor 7 passes through the top and bottom of the inner wall of the fixing groove 6 and is connected to the connecting plate 5. The asymmetric resistors 7 among the plurality of resistors 7 have different resistance values. The rotating plate 4 drives the plurality of connecting plates 5 on the rotating plate 4 to rotate around the axis. Since the lead wire is fixed and abuts against the connecting plate 5, the pin 1 is adjusted to abut against different connecting plates 5 through the rotation of the rotating plate 4, thereby changing the resistor 7 connected to the pin 1.

[0029] like Figure 4 As shown, a chamber 9 is provided inside the main body 2, and the chamber 9 is loaded with an electrolyte solution, which increases the capacitance. A circular isolation plate 10 is fixedly installed inside the chamber 9, and the axial direction of the circular isolation plate 10 is consistent with the axial direction of the main body 2. The circular isolation plate 10 is made of insulating material to prevent short circuit in the circuit where the capacitor is located. A cathode rod 11 is fixedly installed on the bottom surface of the circular isolation plate 10, and a cathode metal foil 12 is fixedly installed on the outer surface of the cathode rod 11. An anode metal foil 13 is provided inside the chamber 9, and the anode metal foil 13 is fixedly connected to the top and bottom of the inner wall of the chamber 9. Since charges are always accumulated on adjacent metal surfaces, cathode metal foil 12 and anode metal foil 13 are used, and electrolytic paper 14 is provided between the cathode metal foil 12 and the anode metal foil 13. The electrolytic paper 14 prevents the cathode metal foil 12 from being directly connected to the anode metal foil 13, and at the same time, the electrolytic paper 14 inhibits the flow of electrons. The electrons of the cathode metal foil 12 enter the anode metal foil 13 through the electrolytic paper 14, and the electrons in the electrolyte solution directly enter the anode metal foil 13.

[0030] like Figure 4 As shown, two carbon rods 15 are fixedly installed on the upper surface of the circular isolation plate 10 corresponding to the pin 1, and each carbon rod 15 passes through the main body 2 and abuts against the connecting plate 5 on the bottom of the rotating plate 4. A hollow area 18 is formed between the circular isolation plate 10 and the top of the inner wall of the chamber 9. The circular isolation plate 10 prevents the electrolyte solution in the chamber 9 from directly contacting the carbon rod 15 to produce a chemical reaction. The hollow area 18 prevents the two carbon rods 15 from being connected, resulting in a short circuit in the capacitor and damage to the capacitor.

[0031] like Figure 4 As shown, the cathode rod 11 is connected to one of the carbon rods 15, and the anode metal foil 13 is connected to the other carbon rod 15. The electrons pass through one of the carbon rods 15, the cathode rod 11, the cathode metal foil 12, the electrolyte solution, the electrolytic paper 14 and the anode metal foil 13 in sequence to reach the other carbon rod 15.

[0032] like Figure 4 As shown, the resistor 7 connected to the connecting plate 5 corresponding to the pin 1 and the carbon rod 15 has the same resistance value. The resistor 7 can effectively filter the voltage or current in the circuit. The pin 1 and the carbon rod 15 are connected to resistors 7 with different resistance values ​​to control the current size of the circuit during the discharge process, and during the charging process, the capacitance of the capacitor can be changed.

[0033] like Figure 2-3 As shown, multiple connecting plates 5 are distributed in a circle around the axis of the rotating plate 4. During the rotation, the connecting plates 5 corresponding to the upper surface and the bottom surface of the rotating plate 4 are in contact with the pins 1 and the carbon rods 15 respectively. The pins 1 and the carbon rods 15 are connected to the resistors 7 through the connecting plates 5, and the rotating plate 4 drives the pins 1 and the carbon rods 15 to connect to different connecting plates 5.

[0034] like Figure 4-6 As shown, a vacuum chamber 16 is provided inside the main body 2, and the vacuum chamber 16 wraps the chamber 9. An insulating plate 17 is fixedly installed on the top of the inner wall of the vacuum chamber 16. The vacuum chamber 16 and the insulating plate 17 prevent the capacitor from leaking electricity to damage the equipment and prevent the staff from getting an electric shock. When the vacuum chamber 16 is damaged, the insulating plate 17 still takes effect.

[0035] Working principle: The staff connects the double-layer capacitor to the circuit, and rotates the rotating plate 4 on the adjusting device 3 as needed, changes the pin 1 and the carbon rod 15 to connect to the corresponding connecting plate 5, so as to achieve the effect of changing the resistance value of the resistor 7. During the charging process, the circuit is turned on, and the electrons enter the adjusting device 3 through one of the pins 1. In the adjusting device 3, the electrons pass through the connecting plate 5 on the upper surface of the rotating plate 4, the resistor 7 and the corresponding connecting plate 5 in turn and enter the main body 2. The carbon rod 15 connected to the cathode metal foil 12 transmits the electrons to the cathode metal foil 12, and the electrons gradually increase on the cathode metal foil 12. Add, and form an electric field, the end where electrons flow into is the negative electrode, due to mutual repulsion in the same direction, the electrons on the anode metal foil 13 enter the circuit through the anode metal foil 13, the carbon rod 15, the adjustment device 3 and the pin 1 in turn, when the electric field strength reaches equilibrium, the capacitor will no longer absorb and release electrons, then the electrons flow into the negative electrode, and the electrons flow out of the positive electrode; in the process of releasing points, the staff rotates the adjustment device 3 as needed, changes the resistance value of the resistor 7 connected to the pin 1, and then changes the size of the current, and the electrons on the cathode metal foil 12 return to the anode metal foil 13 through the electrolytic paper 14 and the electrolyte solution in turn.

[0036] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
