[0002] The filter element of the water purifier is used to purify polluted water to the state required for production and life, that is, to make the water reach a certain degree of cleanliness. In this process, it needs to go through multiple purification processes such as filtering and removing impurities, adsorbing harmful substances, and disinfection. Among them, the pp cotton filter element is the primary filtration structure for purifying water. It can filter large particles of impurities in the water.
[0003] After long-term use, the surface of the PP cotton in the current PP cotton filter will be covered with a layer of impurities, which will affect the subsequent filtering effect and speed. Therefore, the PP cotton needs to be regularly disassembled for cleaning or replacement. It is more troublesome to use. Secondly, there is no supporting structure inside the existing PP cotton filter. If the water pressure is too high, the PP cotton will be deformed, affecting the filtering effect. Therefore, the utility model proposes a PP cotton filter structure. Utility Model Content

[0023] like Figure 1-Figure 4 As shown, it relates to a PP cotton filter element structure, including an outer shell 1, the top of the outer shell 1 is open, and the top of the outer shell 1 is fixedly connected to a top cover 2 by a thread, PP cotton 3 is arranged inside the outer shell 1, and the inside of the PP cotton 3 is hollow, and a plurality of support rods 4 for supporting the PP cotton 3 are fixed at the bottom of the inner shell 1, a water inlet pipe 7 is fixedly connected to the side of the top cover 2, and the water inlet pipe 7 is located on the outside of the PP cotton 3, a water outlet pipe 8 and a backwash pipe 14 are fixedly connected to the middle of the top cover 2, and the water outlet pipe 8 and the backwash pipe 14 are both connected to the inside of the PP cotton 3, and a sewage pipe 15 is fixedly connected to the bottom of the outer shell 1.
[0024] The inner bottom wall of the housing 1 and the inner top wall of the top cover 2 are both fixedly connected with an inner ring plate 5 and an outer ring plate 6 , and the PP cotton 3 is clamped between the inner ring plate 5 and the outer ring plate 6 .
[0025] The bottom and top of the PP cotton 3 can be limited and fixed by the inner ring plate 5 and the outer ring plate 6.
[0026] The side of the PP cotton 3 is provided with a plurality of through holes 31 for passing the support rods 4 .
[0027] When the support rod 4 passes through the PP cotton 3, it can support the PP cotton 3 to prevent the PP cotton 3 from being deformed under strong water pressure.
[0028] The middle parts of the backwash pipe 14 and the sewage pipe 15 are fixedly connected with valves 16 , and the sewage pipe 15 is located outside the PP cotton 3 .
[0029] When the PP cotton 3 needs to be cleaned, the valve 16 can be opened to connect water from the backwash pipe 14. The water enters the PP cotton 3 and passes through the PP cotton 3, thereby flushing away the dirt and impurities attached to the PP cotton 3. The flushed impurities are discharged from the drain pipe 15 along with the water.
[0030] An annular groove 17 is formed at the top of the side wall of the housing 1 , a sealing ring 18 is fixed inside the annular groove 17 , and the sealing ring 18 is in contact with the inner wall of the top cover 2 .

[0035] Working principle: During installation, first connect the water inlet pipe 7 to the pipeline, and then connect the butt joint pipe 10 to the other end of the pipeline. Since the butt joint pipe 10 is connected with a hose 9, the butt joint pipe 10 can move more freely and flexibly. When purifying water, water enters the shell 1 from the water inlet pipe 7, then passes through the PP cotton 3 and is discharged from the water outlet pipe 8, achieving preliminary filtration and purification of the water. When it is necessary to clean the surface of the PP cotton 3, open the valves 16 on the backwash pipe 14 and the drain pipe 15, inject water from the backwash pipe 14, and the water passes from the inside of the PP cotton 3 to the outside to flush away the impurities on the surface of the PP cotton 3, and finally the impurities are discharged from the drain pipe 15. When the PP cotton 3 needs to be replaced, the shell 1 can be unscrewed from the bottom of the top cover 2, and then the PP cotton 3 can be taken out for replacement.
