The top inner wall of the container 1 is fixedly connected to a cleaning assembly, which is used to clean the inner wall of the container 1.

[0025] Reference Figure 4 , Figure 5 The cleaning assembly includes a housing 16. A second motor 17 is fixedly connected to the inner wall of the top of the housing 16. The second motor 17 has a simple structure, is easy to maintain, does not rely on fuel, and is generally more reliable and has a longer lifespan than other types of motors. A rotating rod 18 is fixedly connected to the drive end of the second motor 17. Two fixed supports 19 are fixedly connected to the inner wall of the top of the housing 16. The fixed supports 19 can provide a firm support point to ensure the stability of the structure or equipment during use and reduce shaking and displacement. A rotating block 20 is rotatably connected to the outer wall of the rotating rod 18. A fixed rod 21 is fixedly connected to the inner wall of the rotating block 20. Due to its design and installation method, the fixed rod 21 can provide a stable support and reduce swaying or movement caused by external forces. A water outlet 22 is fixedly connected to the bottom end of the rotating block 20. Rotating columns 23 are rotatably connected to the inner walls of the two fixed supports 19 on their adjacent sides. The design of the rotating columns 23 is relatively simple and easy to manufacture and maintain. Rotating rings 24 are fixedly connected to the outer walls of the two rotating columns 23.

[0026] Reference Figure 3 - Figure 5A blade 15 is fixedly connected to the outer wall of the bottom end of the round rod 7. Due to its geometric shape, the round rod 7 maintains good stability and resists lateral displacement when subjected to lateral loads. The inner wall of the rack disc 8 meshes with the outer wall of the gear 10. The outer wall of the gear 12 meshes with the inner wall of the rack disc 13. The gear 12 can be designed and manufactured to very precise specifications to meet the requirements of precision machinery. The outer wall of the fixed rod 21 is rotatably connected to the inner wall of the rotating ring 24, and the outer wall of the gear 10 meshes with the outer wall of the gear 12. A shell 16 is fixedly connected to the inner wall of the top of the tank 1.

The outer wall of the hollow column 14 is rotatably connected to the inner wall of the bottom end of the tank 1.

[0027] Working principle: Starting motor 6 drives the round rod 7 to rotate, which in turn drives the rack disk 8 to rotate. Simultaneously, the rotation of rack disk 8 drives gear 10 to rotate. Gear 10 meshes with gear 12, which in turn meshes with rack disk 13, driving rack disk 13 to rotate. Hollow column 14 is fixed to the inner wall of rack disk 13. The rotation of rack disk 13, in turn, drives hollow column 14 to rotate. At this time, blades 15 are fixed to the outer wall of hollow column 14 and the outer wall of round rod 7, rotating in opposite directions. This achieves thorough stirring and reaction. Thorough stirring increases the contact area of ​​reactants in the methanol-water solution, accelerating the reaction rate and making the electrolysis process faster and more efficient. Stirring also ensures uniform distribution of methanol and water in the electrolyte, increasing the amount of substances effectively participating in the electrolysis reaction, thereby increasing hydrogen production.

[0028] When cleaning of the inner wall is required, motor 17 is activated, driving the rotating rod 18 to rotate. The outer wall of motor 17 is rotatably connected to the inner wall of the rotating block 20. Because the rotating rod 18 is inclined, the rotating block 20 oscillates during rotation. At this time, the fixed rod 21 rotates on the inner wall of the rotating ring 24. The rotating ring 24 drives the rotating column 23 to rotate on the inner wall of the fixed support 19, thus achieving the cleaning effect. Cleaning removes salt crystals or other contaminants formed on the inner wall. These contaminants hinder ion migration during electrolysis, reducing electrolysis efficiency. Regular cleaning maintains the cleanliness of the electrode surface, ensuring the smooth progress of the electrolysis reaction.
