The development of household appliance products not only improves the quality of life but also promotes energy utilization efficiency and environmental protection. With the progress of technology and the improvement of people's living standards, household appliance products are constantly innovating and upgrading to meet people's growing needs and expectations. The coating roller can ensure that the heat insulation material is evenly coated on the surface or internal structure of household appliance products, avoiding uneven coating, which is crucial for ensuring the consistent heat insulation performance of household appliance products on the entire surface or internal structure.

[0003] The coating roller for traditional heat insulation materials used in household appliances is usually made of wear-resistant materials such as silica gel, rubber or polyurethane. These materials can maintain good wear resistance during long-term use, ensuring the continuous stability of the coating process. To ensure good coating effect of the coating roller, its surface is usually subjected to special treatment, such as frosting, polishing or coating a special coating, to increase surface roughness or reduce surface tension, so as to better control the coating thickness and uniformity.

[0004] However, for the coating roller of traditional heat insulation materials used in household appliances, the coating roller cannot be easily cleaned, and the operator may need more time and energy to handle the cleaning work, which may reduce the production efficiency because the cleaning time will increase the downtime of the production line. Therefore, a coating roller for heat insulation materials used in household appliances is proposed to solve the above problems. Summary of the Utility Model

[0032] Specifically, rotate the lead screw 4, drive the slider 7 to move through the lead screw 4, then drive the scraper 9 to move through the slider 7, and then drive the nozzle 10 to move through the scraper 9, so as to place the scraper 9 on the surface of the coating roller 2. Then, since the magnet 8 fixes the connecting frame 3, start the coating roller 2 again, and clean its surface through the scraper 9 and the nozzle 10, which can quickly and effectively remove impurities and residues on the surface of the coating roller 2, thereby reducing the downtime of the production line and improving production efficiency. At the same time, regularly cleaning the surface of the coating roller 2 can prevent impurities or residues from contaminating the coating material, maintain the stability and consistency of the coating quality, ensure product quality. Then rotate the worm 11, utilize its meshing with the worm gear 12 to ensure the transmission of large torque and moment, and thus drive the scraper 9 to rotate through the worm gear 12, so as to clean the coating roller 2 at different angles, which can ensure that each area of the surface of the coating roller 2 is cleaned, minimize the accumulation of residues, which helps to maintain the coating quality and avoid the influence of impurities on the production line.

[0033] Refer to Figure 1 , the switch assembly includes a first knob 6 and a second knob 13, the outer wall of the first knob 6 is fixedly connected to one end of the outer wall of the lead screw 4, and the outer wall of the second knob 13 is fixedly connected to one end of the outer wall of the worm 11.

[0034] Specifically, rotate the lead screw 4 and the worm 11 through the first knob 6 and the second knob 13. Since the surfaces of the first knob 6 and the second knob 13 have textures, they can provide better hand feeling and grip, increasing the operator's control over the rotating structure, which helps to reduce sliding and out-of-control during operation, and improve the accuracy and stability of operation.

[0036] Specifically, press the sliding column 20 to compress the spring 16 driven by the sliding column 20. At the same time, move the sliding column 20 so that the sliding ball 17 can slide. Then place the water pipe inside the connecting column 14, and then release the sliding column 20. The spring 16 rebounds to drive the sliding column 20 back to its original position, so as to push the sliding ball 17 to its original position by the sliding column 20 to clamp the water pipe, which can be easily moved or repositioned when needed, thus providing greater flexibility. This is very useful for adjusting the pipeline layout, replacing equipment, or performing maintenance and repairs. At the same time, a rubber ring 15 is provided inside to achieve a certain sealing effect and prevent water leakage.

[0037] Working principle: Fix the coating roller 2 through the fixedly connected connecting rod 1, and then fix the connecting frame 3 inside the device through the magnet 8 fixedly connected to the outer wall of the connecting frame 3. When cleaning the coating roller 2, rotate the first knob 6 to drive the fixedly connected lead screw 4 to rotate through the first knob 6. Then drive the threaded slider 7 to slide inside the first limiting groove 5 where it is slidably connected through the lead screw 4. Then drive the fixedly connected scraping knife 9 to move to the surface of the coating roller 2 through the slider 7. At the same time, drive the fixedly connected nozzle 10 to move through the scraping knife 9. Then rotate the second knob 13 to drive the fixedly connected worm 11 to rotate through the second knob 13. Then drive the meshing-connected worm gear 12 to rotate through the worm 11. Then drive the fixedly connected scraping knife 9 to rotate through the worm gear 12. At the same time, drive the fixedly connected nozzle 10 to rotate through the scraping knife 9, so as to adjust different angles for cleaning. Then slide the sliding column 20 to compress the fixedly connected spring 16 driven by the sliding column 20. At the same time, the movement of the sliding column 20 makes the sliding ball 17 slidably connected inside the second limiting groove 19 slide. Only then can the water pipe be placed inside the connecting column 14. Then release the sliding column 20, and the spring 16 rebounds to drive the fixedly connected sliding column 20 back to its original position. Clamp it through the coil 18 fixedly connected to the connecting column 14. At the same time, fix the sliding ball 17 by moving the sliding column 20, so as to fix the water pipe.
