Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 , Figure 2 and Figure 3The embodiment of the utility model provides a system for controlling the rotation of an electrode, comprising a frame 1 and a working electrode that can be inserted into an electrolytic cell, and also comprising a control box mounted on the frame 1, wherein the control box is provided with a motor 4 for controlling the rotation of an electrode rod 5, and a control component for controlling the rotation of the motor 4 is integrated in the control box, wherein the electrode rod 5 is coaxially connected to the working electrode, and the control box is also provided with a conductive structure 6 for transmitting the signal output by the working electrode to an external measuring device. In this embodiment, by integrating the control component in the control box, the system can be made more compact, the structure can be simplified, and the motor 4 can be controlled more stably, with higher reliability. Specifically, the control component drives the motor 4 to work, and the motor 4 is connected to the electrode rod 5 through the coupling 15, driving the electrode rod 5 to rotate, and then the electrode rod 5 is coaxially connected to the working electrode, and the coupling 15 can also be used to connect, so that the working electrode rotates in the electrolytic cell, stirring the electrolyte, and the signal output by the electrolyte is fed back to the electrode rod 5 through the working electrode, and then the electrode rod 5 is output to the external measuring device through the conductive structure 6. The measuring device can be a device for recording and analyzing signals. It is an existing device and will not be described in detail here. Through this integrated control component method, the system structure can be made more compact, and the control motor 4 is directly output in the housing, which can be free from external interference, improve the reliability of the control of the motor 4, ensure the stable operation of the motor 4, and provide a highly stable rotation action, thereby providing a stable rotation working environment for the electrode for electrochemical characterization.

The control circuit board has an output circuit capable of controlling the rotation speed of the electrode. For example, the output circuit may be a circuit board with a variable resistance value with a carbon film.

Of course, in addition to using the adjustment knob 7, an adjustment rod that slides up and down can be used. The principle is the same and will not be repeated here.
