[0024] Please refer to Figures 1 - 5 , the present utility model provides a highly efficient water purification PP cotton filter element, including a housing 1, a cover plate 2 is installed on one side of the housing 1, a threaded cylinder 3 is fixedly connected to one side of the cover plate 2, a fixed pipe 4 is threadedly connected inside the threaded cylinder 3, through holes are provided on the outer side of the fixed pipe 4, a PP cotton filter element 5 is placed inside the fixed pipe 4, a water outlet pipe 6 is communicated with the outside of the housing 1, a water inlet pipe 7 is fixedly connected to the cover plate 2, the water inlet pipe 7 penetrates through the cover plate 2, an output pipe 8 is fixedly connected to one side of the fixed pipe 4, the output pipe 8 is communicated with the fixed pipe 4, a circular through groove is provided on one side of the housing 1, the circular through groove is matched with the output pipe 8, control valves 9 are installed on both the water outlet pipe 6 and the output pipe 8. When in use, water enters the housing 1 through the water inlet pipe 7, the water passes through the PP cotton filter element 5 for filtration, and then the water passes through the fixed pipe 4 and enters the housing 1. At this time, the control valve 9 on the water outlet pipe 6 is opened, and the control valve 9 on the output pipe 8 is closed. The filtered water can only flow out of the housing 1 through the water outlet pipe 6, and the impurities in the water are blocked inside the fixed pipe 4 on the inner side of the PP cotton filter element 5 at this time. When cleaning the accumulated impurities, the control valve 9 on the water outlet pipe 6 is closed at this time, the control valve 9 on the output pipe 8 is opened, and water is conveyed into the housing 1 through the water inlet pipe 7 again. The water flow impacts the impurities and outputs the impurities from the housing 1 through the output pipe 8, cleaning the impurities on the inner side of the PP cotton filter element 5. At the same time, it is not necessary to disassemble the PP cotton filter element 5 during cleaning, making it more convenient to clean the impurities.

[0025] As Figure 2 shown in Figure 3 , a conical cylinder 10 is fixedly connected to one side of the fixed pipe 4, the output pipe 8 penetrates through the conical cylinder 10, a rubber pad is fixedly connected to one side of the conical cylinder 10, the rubber pad contacts the inner wall of the housing 1, and the control valve 9 on the output pipe 8 is located inside the conical cylinder 10. By means of the rubber pad, the gap between the conical cylinder 10 and the inner wall of the housing 1 is reduced, reducing the water entering the conical cylinder 10 and protecting the control valve 9.

[0026] As shown Figure 2 in FIG. 1, a fixing ring 11 is fixedly connected to the inner wall of the fixing pipe 4. The inner diameter of the fixing ring 11 is the same as the diameter of the output pipe 8. The distance between the fixing ring 11 and the inner wall of the fixing pipe 4 is the same as the thickness of the PP cotton filter element 5. When installing the PP cotton filter element 5, the PP cotton filter element 5 is inserted between the fixing ring 11 and the fixing pipe 4 to limit the position of the PP cotton filter element 5. The inner wall of the conical cylinder 10 is inclined. When cleaning impurities, the inclined inner arc surface facilitates the impurities to pass through the fixing ring 11 and enter the output pipe 8.

[0027] As shown Figure 5 in FIG. 2, one side of the housing 1 is fixedly connected to a fixing plate 12. Two support rods 13 are fixedly connected between the fixing plate 12 and the cover plate 2. Installation grooves are provided on one side of the two support rods 13, and installation members 14 are provided in the installation grooves. The installation members 14 are used to fix the cover plate 2. The installation member 14 includes a fixing seat 141. The fixing seat 141 is located in the installation groove and is fixedly connected to the support rod 13. Two square through grooves are provided on the cover plate 2, and the square through grooves are matched with the fixing seat 141. A square groove is provided on one side of the fixing seat 141, and a clamping block 142 is slidably connected in the square groove. One side of the clamping block 142 is provided with an inclined surface. A spring 143 is fixedly connected between the clamping block 142 and the side wall of the square groove. When installing the cover plate 2, align the square through groove on the cover plate 2 with the fixing seat 141, so that the fixing seat 141 passes through the square through groove. When passing through, the inclined surface on one side of the clamping block 142 abuts against the side wall of the square through groove. After being blocked, the clamping block 142 is squeezed into the square groove to avoid, and the spring 143 is compressed. When the clamping block 142 passes over the cover plate 2, it pops out under the push of the spring 143 and clamps the cover plate 2 to fix the cover plate 2. The installation of the cover plate 2 is more convenient and fast. An elastic pad is provided on the inner side of the cover plate 2. By squeezing with the housing 1, water leakage is avoided. When removing, just press the two clamping blocks 142, press the clamping blocks 142 back into the square groove, and then pull out the cover plate 2.

[0028] As shown Figure 4 in FIG. 3, a round rod 144 is fixedly connected to the side wall of the square groove on the fixing seat 141. A circular through hole is provided on the clamping block 142, and the round rod 144 is located in the circular through hole. The clamping block 142 is slidably connected to the round rod 144. The clamping block 142 can only slide on the round rod 144, which can avoid the clamping block 142 from skewing when sliding in the square groove, resulting in loosening when clamping the cover plate 2 and further causing water leakage.

[0029] Working principle: When installing the cover plate 2, align the square slot on the cover plate 2 with the fixing seat 141, so that the fixing seat 141 passes through the square slot. When passing through, the inclined surface of one side of the block 142 abuts against the side wall of the square slot. After being blocked, the block 142 is squeezed into the square slot to avoid it, and the spring 143 is compressed. When the block 142 passes over the cover plate 2, it pops out under the push of the spring 143, clamps the cover plate 2, and fixes the cover plate 2. At this time, the output pipe 8 passes through the circular slot, and water enters the housing 1 through the water inlet pipe 7. The water passes through the PP cotton. The filter element 5 filters, and then the water passes through the fixed pipe 4 into the shell 1. At this time, the control valve 9 on the water outlet pipe 6 is opened, and the control valve 9 on the output pipe 8 is closed. The filtered water can only flow out of the shell 1 through the water outlet pipe 6. The impurities in the water are blocked on the inner side of the PP cotton filter element 5 inside the fixed pipe 4. When the accumulated impurities are cleaned, the control valve 9 on the water outlet pipe 6 is closed, and the control valve 9 on the output pipe 8 is opened. Water is transported into the shell 1 through the water inlet pipe 7 again. The water flow impacts the impurities and outputs the shell 1 through the output pipe 8.

[0030] Of course, the present utility model may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present utility model.
