The slide 504 is opened above the gear ring groove 503, and a circular protrusion matching the internal shape of the slide 504 is provided below the mounting plate 501. The mounting bracket 505 is fixedly connected to the lower surface of the primary filter cartridge 2. The cleaning brush 506 is fixedly connected to the lower part of the gear 502 and rotatably connected to the lower groove inside the mounting bracket 505. The outer surface of the cleaning brush 506 contacts the outer surface of the primary filter cartridge 2. A threaded hole is opened above the mounting plate 501, and the motor 5 and the mounting plate 501 are connected by bolts through the threaded hole.

[0026] A knob 201 is rotatably connected to the bottom of the primary filter cartridge 2. A limit block 202 is fixedly connected above the knob 201 and is located inside the lower part of the primary filter cartridge 2. A limit groove 203 is opened at the bottom of the submersible electric pump 1. The limit block 202 matches the inside of the limit groove 203. The opening of the limit groove 203 is square and the inside is circular. Filter elements 301 are installed inside the primary filter cartridge 2. There are four filter elements 301 arranged in a circle.

[0027] In this embodiment, the motor 5 drives the gear 502 to rotate along the gear groove 503, so that the cleaning brush 506 moves to clean a larger area while rotating and cleaning the outer surface of the primary filter cartridge 2. The primary filter cartridge 2 and the submersible pump 1 are fixed together by the cooperation of the limiting block 202 and the limiting groove 203. Large particulate impurities are filtered through the primary filter cartridge 2, and small particulate impurities are filtered through the filter element 301, so that the filtration effect is better.

[0028] Example 2: Based on Example 1, please refer to... Figures 1-4This system allows for quick filter replacement, and the anti-slip grooves and counterweights ensure stable operation of the entire device in water. A guide rail 302 is provided on the outer surface of the submersible pump 1, and a pressure plate 3 is mounted on its outer surface. The inner surface of the pressure plate 3 has protrusions that match the inside of the guide rail 302.

Pressing down the pressure plate 3 and then rotating the pressure plate 3 can release the filter element 301 and allow it to be replaced. The spring 304 makes the filter element 301 fit more tightly with the pressure plate 3, improving the fixing effect. The anti-slip groove and the counterweight 401 make the whole equipment work more stably in the water.

[0030] Working Principle: The motor 5 drives the gear 502 to rotate along the gear groove 503, causing the cleaning brush 506 to move and clean a wider area while rotating and cleaning the outer surface of the primary filter cartridge 2. The limiting block 202 and the limiting groove 203 work together to fix the primary filter cartridge 2 and the submersible pump 1. The primary filter cartridge 2 filters large particles of impurities, and then the filter element 301 filters small particles of impurities, resulting in better filtration. The pressure plate 3 fixes the filter element 301. Pressing down the pressure plate 3 and then rotating it releases the filter element 301 for replacement. The spring 304 ensures that the filter element 301 fits more tightly against the pressure plate 3, improving the fixing effect. The anti-slip groove and the counterweight 401 make the whole equipment work more stably in the water.
