[0028] Example:

[0029] Reference Figures 1 to 6 This embodiment proposes a modular constant potential instrument, including a detachably mounted electric control body and a heat dissipation module. A normally closed component is arranged at the inner bottom of the electric control body. When the heat dissipation module is installed to the bottom of the electric control body, the top of the heat dissipation module is suitable for pushing open the normally closed component to make the space inside the electric control body and the heat dissipation module connected; when the heat dissipation module is removed, the normally closed component returns to a closed state, thereby isolating the inside of the electric control body from the outside, preventing dust from entering the inner cavity of the electric control body through the bottom of the electric control body when not in use. Only when the heat dissipation module is installed during operation, the normally closed component automatically opens the connection between the electric control body and the heat dissipation module. Through the split modular design of the electric control body and the heat dissipation module, the constant potential instrument is disassembled into two major parts, thereby providing convenience in its transportation, installation and other scenes; at the same time, due to the modular design, dust is easily infiltrated into the openings of the electric control body and the heat dissipation module. In this embodiment, through the design of the normally closed component, only after the heat dissipation module is installed, the normally closed component in the electric control body will open the space connection from the bottom of the electric control body to the inner cavity of the heat dissipation module, thereby avoiding dust from entering the inside of the electric control body when not in use.

[0030] like Figures 2 to 5 As shown, the normally closed component includes a ventilation plate, a movable plate arranged below the ventilation plate, and a guide portion. The ventilation plate is fixedly mounted on the inner wall of the electric control body, and the movable plate is movably mounted between the four inner walls of the electric control body in a limited manner. The guide portion is suitable for limiting the movement of the movable plate within a set range below the ventilation plate. The ventilation plate includes an adjustment hole. The top of the movable plate is provided with an adjustment member with an outer diameter the same as that of the adjustment hole. When the movable plate moves, the adjustment member fits against the hole wall of the adjustment hole and moves up and down. The adjustment member includes a long hole. When the heat dissipation module is not installed, the adjustment member falls freely with the movable plate to the lowest end of its movable range. At this time, the top of the long hole is located below the adjustment hole, so that the adjustment member blocks the adjustment hole. When the heat dissipation module is installed, it pushes the movable plate upward, and the long hole is connected at the top and bottom of the ventilation plate at the same time. As shown Figure 2 , Figure 3 As shown, a heat dissipation top plate is provided on the top of the inner wall of the heat dissipation module, a gap is left between the top of the heat dissipation top plate and the top surface of the inner wall of the heat dissipation module, an interference rod is fixedly installed on the top surface of the heat dissipation top plate, and when the heat dissipation module is close to the bottom of the electric control body, the interference rod is suitable for contacting the movable plate.

[0031] The guide part is set as a guide rod, and a spring is arranged outside the guide rod, and the bottom of the spring is fixedly connected to the movable plate. When the heat dissipation module is installed at the bottom of the electric control body, the spring can provide a certain buffering effect, so that the heat dissipation module and the movable plate can ensure stable contact.

[0032] The inner wall of the electric control body is detachably mounted with a support plate at a set distance below the movable plate, and the top surface of the support plate is the limit end of the movable plate's downward movement. The support plate can flexibly control the farthest end of the movable plate's downward movement. Due to the limitation of the internal space of the potentiostat, the support plate can be adjusted as needed to adjust the movable range of the movable plate to a smaller range, which can minimize the space actually occupied by the normally closed component.

[0033] To facilitate the wiring of this constant potential instrument, Figure 2 , Figure 5 As shown, the electric control body includes a wire group, which extends downward along the inner walls on both sides of the electric control body, and an electrical connector is integrated in the area below the inner wall of the electric control body; a power module is provided on the inner side of the heat dissipation module, and the power module includes a power connector, which is provided on the inner wall of the heat dissipation module opposite to the wire group, and the top of the power connector extends out of the top surface of the heat dissipation module. The movable plate and the ventilation plate are provided with avoidance grooves suitable for accommodating the wire group, and the heat dissipation top plate is provided with avoidance grooves suitable for accommodating the power connector. Of course, the actual length of the wire group can be longer, and it can also be bent and fixed in the upper inner wall of the electric control body. Figure 2 The straight line groups shown are for illustration purposes only.

[0034] A base frame is provided at the bottom of the heat dissipation module, and the base frame is suitable for spacing the bottom surface of the heat dissipation module from the ground, thereby ensuring that the heat dissipation module can discharge the heat absorbed by the power module and the electric control body in time.

[0035] Both sides of the bottom surface of the electric control body and both sides of the top surface of the heat dissipation module are provided with fixing parts. After the electric control body and the heat dissipation module are spliced, the fixing parts on the upper and lower sides are matched and fixed. The fixing parts can be as follows Figure 1 The combination of screw holes on the fixing plate shown can easily fix the two together through a combination of nuts.

[0036] A top cover is fixedly installed on the top of the electric control body, and a pull ring is provided on the top of the top cover. The pull ring is suitable for adapting to the lifting mechanism. The lifting mechanism can lift the entire constant potentiostat by hooking the pull ring, so as to facilitate transportation.

[0037] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
