Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1 to 4. The utility model provides a filter that is easy to disassemble, including a cover shell 1, a mounting plate 5 is fixedly installed at the bottom end of the cover shell 1, a fixing seat 18 is fixedly installed at the bottom end of the cover shell 1, a spring 17 is fixedly installed at the top of the fixing seat 18, a filter element 15 is sleeved on the outer side of the fixing seat 18, a filter plate 16 is fixedly installed in the filter element 15, the top of the spring 17 abuts against the bottom end of the filter plate 16, a slot 8 is provided at the top end of the cover shell 1, a cover plate 7 is inserted in the slot 8, a rotating member 9 is sleeved on the outer side of the cover shell 1, a pressure ring 10 is fixedly installed at the top end of the rotating member 9, the bottom end of the pressure ring 10 abuts against the top end of the cover plate 7, a positioning rod 12 is fixedly installed at the bottom end of the cover plate 7, a positioning seat 13 is fixedly installed on the top end of the filter element 15, and the bottom end of the positioning rod 12 is inserted in the positioning seat 13.

A scraper ring 19 is sleeved on the outside of the filter element 15, and two connecting rods 20 are fixedly installed on the bottom end of the scraper ring 19. The bottom ends of the two connecting rods 20 extend out of the mounting plate 5. Pull rings 6 are fixedly installed on the bottom ends of the two connecting rods 20. The scraper ring 19 is convenient for cleaning impurities on the surface of the filter element 15. A limit ring 11 is sleeved on the outside of the top of the cover 1. The rotating member 9 is sleeved on the outside of the limit ring 11. The limit ring 11 can limit the rotating member 9. Two openings 14 are reserved at the top of the pressure ring 10. 14 is convenient for the cover plate 7 to be inserted into the card slot 8, the bottom end of the mounting plate 5 is fixedly mounted with a water outlet pipe 2, the right side of the cover shell 1 is fixedly mounted with a water inlet pipe 3, the water flow is convenient to be filtered through the water inlet pipe 3 and the water outlet pipe 2 through the filter, the left side of the cover shell 1 is fixedly mounted with a sewage pipe 4, the sewage pipe 4 is fixedly mounted with a valve, the sewage pipe 4 is convenient to discharge the filtered impurities through the sewage pipe 4, the positioning rod 12 is set in a hexagonal shape, and the positioning seat 13 is set corresponding to the positioning rod 12, and this design is conducive to the use of this filter.

Working principle: When in use, by pulling the pull ring 6 upward, the pull ring 6 drives the connecting rod 20 to extend into the housing 1, so that the scraper ring 19 slides upward along the outer side of the filter element 15, the impurities attached to the outer side of the filter element 15 can be scraped off, and then the valve of the sewage pipe 4 is opened, and the impurities can be flushed and discharged by water flow. When the filter element 15 needs to be replaced, the rotating member 9 is rotated 90 degrees, and the rotating member 9 drives the pressure ring 10 to rotate, so that the two openings 14 correspond to the two sides of the cover plate 7. At this time, the cover plate 7 loses its limit, and the spring 17 returns to drive the filter plate 16 to rise, so that the cover plate 7 can be extended out of the card slot 8, and the filter element 15 extends out of the housing 1, so that it is convenient to take out the filter element 15 for replacement. This kind of filter that is easy to disassemble is easy to use.
