Technical Field

[0001] This utility model relates to the field of experimental equipment technology, specifically to a portable electrolytic cell experimental device for simulating electroplating. Background Technology

[0002] Electroplating is a common technique for depositing metal layers on metal surfaces based on the principle of electrolysis. It is widely used in industrial processing, decorative protection, and chemical education. In chemistry teaching and experimental demonstrations, electroplating experiments help students intuitively understand electrochemical processes.

[0003] Existing electroplating experimental apparatuses typically employ a modular design, including separate electrolytic cells, electrodes, an external DC power supply, an electroplating solution container, and auxiliary tools. During use, each component requires manual assembly: the electrodes are connected to the power supply via wires, often secured by clips or welding, but this is prone to circuit interruptions due to poor contact; the electrolyte must be taken from a separate container, making leakage during transportation or operation likely; and waste disposal relies on additional beakers or containers, increasing cleaning steps.

[0004] The inventors of this application have discovered that existing electroplating experimental devices are large in size and have scattered components, making them difficult to carry and store, and thus unable to meet the needs of mobile teaching or outdoor experiments. Utility Model Content

[0005] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide a portable electrolytic cell experimental device for simulating electroplating, which is easy to carry, easy to assemble, and improves experimental efficiency.

The plurality of locking plates are arranged at diagonal positions according to the shape of the battery, and a flexible anti-slip pad is provided on the side of the locking plate that is in contact with the battery.

[0008] Preferably, the bottom ends of the Cu electrode and the Fe electrode extend into the first mounting bracket and can be directly connected to the positive and negative terminals of the battery disposed in the first mounting bracket.

[0009] Preferably, the container area is provided with a limiting ring that matches the size of the aviation cup, and the limiting ring is provided with a leak-proof pad.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0022] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0023] Combination Figures 1-3 As shown, the portable electrolytic cell experimental device for simulating electroplating includes a storage box, a battery 8, an aviation cup, an electroplating solution packaging bag 9, a waste liquid bag 10, a pipette 12, and a cleaning cotton pad 11.

[0024] The storage box includes a box body 1 with a storage cavity and a box cover 2 disposed on the box body 1. The inner bottom surface of the box body 1 is provided with a power supply area, a container area, a consumables area 6 and a tool area 7. The battery 8 is detachably disposed in the power supply area. The aviation cup is snapped into the container area. The aviation cup includes a cup body 13 and a snap-fit ​​seat disposed on the bottom surface of the cup body 13 for fixing the battery 8. The bottom surface of the aviation cup is also provided with a Cu electrode 15 and an Fe electrode 14 that pass through it. The electroplating solution packaging bag 9 is disposed in the consumables area 6. The waste liquid bag 10 is folded and disposed in the consumables area 6. The pipette 12 is disposed in the tool area 7. The cleaning cotton pad 11 is disposed in the tool area 7.

[0025] In one embodiment of this utility model, such as Figure 2As shown, the power supply area is provided with a second locking seat for fixing the battery 8. Both the first and second locking seats include several locking plates 4. The locking plates 4 are arranged diagonally according to the shape of the battery 8, and a flexible anti-slip pad 5 is provided on the side of the locking plate 4 that is in contact with the battery 8. Specifically, the locking plates 4 are usually made of a slightly elastic plastic material, such as polypropylene or ABS engineering plastic. The number of them is set according to the shape of the battery 8. For cylindrical batteries 8, three or four locking plates 4 are usually provided to form a stable clamp in a three-point or four-point support manner. The flexible anti-slip pad 5 can be made of rubber or silicone sheet and is fixed to the inside of the locking plate 4 by insert molding or adhesive. Its surface can be designed with small raised textures to increase friction and ensure that the battery 8 can withstand a certain amount of vibration and shaking in both the first and second locking seats without falling off, while also facilitating manual installation and removal.

[0026] In one embodiment of this utility model, such as Figure 3 As shown, the bottom ends of Cu electrode 15 and Fe electrode 14 extend into the first retainer and can be directly connected to the positive and negative terminals of the battery 8 disposed in the first retainer. Specifically, the electrodes are made of metal rods, and their bottoms are machined to form flat contact surfaces. When the battery 8 is inserted into the first retainer, the bottom contact surfaces of the electrodes form a tight physical contact and electrical connection with the electrodes of the battery 8 under the positive pressure applied by the retainer plate 4. This direct connection method eliminates the need for traditional wires and solder joints, which not only reduces contact resistance and ensures current stability, but also simplifies the assembly process and avoids the risk of wire tangling or breakage.

[0027] In one embodiment of this utility model, such as Figure 3 As shown, the container area is equipped with a limiting ring 3 that matches the size of the aviation cup, and the limiting ring 3 contains a leak-proof pad. Specifically, the limiting ring 3 is formed by protruding upward from the inner bottom surface of the box body 1, and its inner contour is in transition or with a small gap with the outer contour of the aviation cup body 13, which can restrict the movement of the aviation cup in the horizontal direction. The leak-proof pad is usually made of closed-cell foam material or elastic rubber. When the aviation cup is placed into the limiting ring 3 and pressed tightly, the leak-proof pad undergoes elastic deformation to form an effective seal, preventing a small amount of liquid that may overflow from the aviation cup from seeping into other areas of the storage box.

[0028] In one embodiment of this invention, the length × width × height of the storage box is no greater than 15cm × 10cm × 5cm. Specifically, this size range is designed and optimized to achieve maximum portability of the device. For example, a typical implementation size can be 14.5cm x 9.5cm x 4.5cm. This compact size ensures that the entire device can be easily placed in a backpack or carried with one hand. At the same time, the internal space, through a reasonable partitioned layout, is sufficient to accommodate all the components required to complete a full electroplating experiment, and the components do not interfere with each other and are easy to access.

[0029] In one embodiment of this invention, the battery 8 is a button cell 8 or a thin cylindrical battery 8. Specifically, the button cell 8 can be a standard 3V lithium battery 8, such as CR2032, which is characterized by its small thickness and ease of integration; the thin cylindrical battery 8 can be a 9V thin cylindrical battery 8, such as 6LR61. The selection of these battery types is mainly based on their advantages of small size, stable voltage, easy commercial availability and low cost. They provide sufficient voltage and current to drive small-scale simulated electroplating reactions, while their shape facilitates effective fixation by the mounting bracket and reliable contact with the electrodes.

[0030] In one embodiment of this utility model, the aviation cup is made of food-grade PP plastic to form a cup body 13 with a volume of 50ml. Specifically, food-grade polypropylene is chosen because it has good chemical stability, can withstand the corrosion of commonly used electroplating solutions, and is non-toxic, odorless, and highly safe. The cup body 13 is usually integrally molded by injection molding, with uniform wall thickness and sufficient mechanical strength. The 50ml volume ensures that the electrode has sufficient immersion area for effective electroplating reaction, controls the amount of electroplating solution used, reduces waste, and keeps the entire aviation cup assembly compact, matching the compact design of the storage box.

[0031] The portable electrolytic cell experimental apparatus for simulating electroplating according to an embodiment of the present invention

[0032] In use, first open the storage box cover 2, remove the battery 8 from the second slot in the power supply area, remove the aviation cup from the limiting ring 3 in the container area, and firmly insert the battery 8 into the first slot at the bottom of the aviation cup. Then, remove the electroplating solution packaging bag 9 from the consumables area 6, and use the pipette 12 in the tool area 7 to transfer a certain amount of electroplating solution into the aviation cup, ensuring that the liquid level submerges the effective part of the electrode. At this time, since the bottom of the electrode has made physical contact with the positive and negative terminals of the battery 8, the circuit is automatically connected, and the electroplating process begins. Observe and record the changes on the electrode surface. After the experiment is completed, use the cleaning cotton pad 11 in the tool area 7 to wipe the electrode and pour the waste liquid into the waste liquid bag 10 in the consumables area 6. Finally, put all components back in place, close the box cover 2, and complete the entire experimental procedure.

[0033] When electrolyte is injected into the aviation cup containing battery 8, a complete closed circuit is automatically formed. Current flows from the positive terminal of battery 8 through one of the electrodes in direct physical contact with it into the electrolyte. Ions in the electrolyte move in a direction under the action of the electric field, completing the transfer of charge. Then the current flows back to the negative terminal of battery 8 through the other electrode, forming a closed loop.

[0034] Taking copper plating on an iron electrode as an example, when using copper sulfate electroplating solution, the copper electrode connected to the positive terminal of the power supply serves as the anode. The metallic copper loses electrons and is oxidized into copper ions that enter the solution. The iron electrode connected to the negative terminal of the power supply serves as the cathode. The copper ions in the solution gain electrons on the surface of the iron electrode and are reduced, forming a metallic copper layer that is deposited on it, thus achieving electroplating. The whole process intuitively demonstrates electrochemical knowledge such as electrolysis and redox reactions.

[0035] The device modularly stores all components through a partitioned storage box design. The aviation cup serves as both an electrolytic cell and a power supply holder. The direct contact connection between the electrodes and the battery 8 eliminates the need for external wires. The limiting ring 3 and the leak-proof pad provide a sealing guarantee. The dedicated electroplating solution packaging bag 9 and waste liquid bag 10 enable the safe handling of reagents and the safe storage of waste liquid. These designs work together to simplify a complex laboratory device and integrate it into a portable, easy-to-use, and safe kit, allowing electroplating experiments to be conducted anytime, anywhere.

[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
