[0038] Real-time cleaning: The cleaning brush 5 is installed inside the filter sub-box 2 to clean the surface of the filter assembly in real time, keep the filter holes unobstructed, and further improve the filtering effect.

[0039] Cleaning the filter surface: As the filter assembly rotates, the cleaning brush 5 can clean the filter surface in real time. It can contact the impurities on the filter and brush them out to keep the filter holes unobstructed. This can avoid the accumulation and blockage of impurities and ensure the stability and continuity of the filtering effect.

[0040] Improve filtration efficiency: By cleaning the filter surface in real time, the cleaning brush 5 can quickly and effectively remove impurities and prevent them from adhering to the filter body 4. This can keep the filter holes clean and improve filtration efficiency and product quality.
