The core of the reverse osmosis system is its water inlet assembly, and the filter core in the water inlet assembly is the key component to ensure water quality. However, due to long-term use, a large amount of pollutants will accumulate on the surface of the filter core, which will seriously affect the filtering efficiency of the filter core and the water production quality of the reverse osmosis system.

Multiple scraping plates 5 are installed on the inner wall of the support ring 4, with three scraping plates 5 forming a group, and four groups in total, installed between the support ring 4. All scraping plates 5 are in contact with the outer side of the filter cartridge body 3. A fitting ring 6 is inserted into the bottom of the inner wall of the water delivery cylinder 1. The bottom of the support ring 4 is rotatably connected to the inner wall of the fitting ring 6. The inlet pipe 11 is installed inside the rear side of the top cover 2 and passes through the top cover 2. The bottom end of the connecting pipe 26 is installed between the rear side of the conveying pipe 25, and the bottom end of the conveying pipe 25 passes through the upper rotating plate 12. Multiple scraping plates 5 are arranged in a ring around the axis of the support ring 4, so that the outer surface of the filter element body 3 is cleaned and scraped by multiple scraping plates 5, reducing the residual pollutants on its surface and thus improving the filtration effect of the filter element body 3. The support ring 4 is sleeved on the outside of the filter element body 3. The top end of the support ring 4 passes through the support groove 14, and the bottom end is inserted into the inner wall of the rotating groove 21. Thus, the support ring 4 rotates along the outside of the filter element body 3, driving multiple scraping plates 5 to scrape and cooperate with the cleaning components, thereby improving the cleaning effect of the filter element body 3. The conveying pipe 25 is designed in a "U" shape, so as to facilitate the subsequent control of the amount of cleaning liquid, thereby reducing the waste of cleaning liquid.

The plurality of connecting rods 19 are evenly distributed with the axis of the lower rotating plate 13 as the center, and the ends away from the lower rotating plate 13 are installed between the tooth ring 15, thereby when the tooth ring 15 rotates, the lower rotating plate 13 is synchronously driven to rotate, so as to drive the plurality of adjusting holes 22 to be in abutment with the bottom end of the conveying pipe 25 one by one, thereby intermittently conveying the cleaning liquid and reducing the waste thereof. The connecting rod 19 is arranged on the inner wall of the support groove 14, thereby when the tooth ring 15 rotates, the plurality of connecting rods 19 are used to synchronously drive the lower rotating plate 13 to rotate.

[0042] In the process of rotating the gear ring 15 along the inner wall of the support groove 14, the lower rotating plate 13 is connected with the gear ring 15 through the connecting rod 19, and the rotating part two 24 at the bottom of the upper rotating plate 12 rotates in the inner wall of the rotating groove two 23, thereby driving the lower rotating plate 13 to rotate synchronously at the bottom of the upper rotating plate 12, and then allowing the plurality of adjusting holes 22 to be matched with the bottom end of the conveying pipe 25 one by one, and at the same time, the output hole 29 is kept unobstructed, so as to realize the intermittent discharging of the cleaning liquid and reduce the waste of the cleaning liquid.

The plug-in part 27 is plugged into the inner wall of the plug-in groove 28, the collecting filter frame 10 is installed between the side away from the counterweight ring 8 of the collecting filter frame 10 and the fitting ring 6, and the collecting filter frame 10 is arranged at the inner wall bottom of the water conveying cylinder 1, and the counterweight ring 8 is sleeved on the lower outer side of the filter core body 3, so that the counterweight ring 8 is arranged to facilitate the counterweight of the collecting filter frame 10 and increase the stability of the plug-in between the collecting filter frame 10 and the filter core body 3.

[0044] When cleaning the outside of the filter core body 3, the collection filter frame 10 is installed between the weight ring 8 on one side and the fitting ring 6 on the other side, so that the collection filter frame 10 filters and collects the waste water and impurities cleaned from the outside of the filter core body 3, thereby reducing excessive impurities and causing the drain pipe of the water delivery cylinder 1 to be blocked. When the collection filter frame 10 and the maintenance cleaning assembly need to be cleaned, the top cover 2 is pulled upwards first, and the support ring 4 is moved upwards, and the plurality of rubber convex balls 20 are gradually separated from the inner wall of the water delivery cylinder 1, so that the fitting ring 6 slides upwards along the inner wall of the water delivery cylinder 1.
