Therefore, by utilizing the setting of the rubber convex balls 20, the fitting ring 6 is fitted with the bottom of the inner wall of the water delivery cylinder 1 to increase the stability of the support ring 4 during the rotation process, and at the same time, it is convenient to pull the top cover 2 upward subsequently to drive it away from the inner wall of the water delivery cylinder 1, so as to clean the collection filter frame 10 and maintain the cleaning components.

When the cleaning and maintenance are completed, the counterweight ring 8 is sleeved on the outside of the filter element body 3, and the collection filter frame 10 is inserted into the gap between the water delivery cylinder 1 and the filter element body 3, and then the top cover 2 is pushed downward to drive the fitting ring 6 to reset along the inner wall of the water delivery cylinder 1, and drive the plug-in portion 27 at the bottom of the counterweight ring 8 to insert into the inner wall of the plug-in groove 28. At this time, the multiple rubber convex balls 20 on the outside of the fitting ring 6 will be clamped and deformed with the inner wall of the water delivery cylinder 1, thereby increasing the stability between the fitting ring 6 and the water delivery cylinder 1, and improving the stability of the support ring 4 during the rotation process. Finally, the top cover 2 is reset to complete the cleaning and maintenance operation.

[0045] Embodiment 5: Based on Embodiment 4, a method for using a filter element cleaning device for a reverse osmosis water inlet assembly is proposed, and the method comprises the following steps:

At this time, start the motor 16 synchronously to drive the gear 17 at the output end to rotate, and at the same time drive the gear ring 15 to rotate on the inner wall of the support groove 14, thereby synchronously driving the support ring 4 to rotate on the inner wall of the water delivery cylinder 1. Since the bottom of the support ring 4 is connected between the rotating member 7 and the rotating groove 21, the support ring 4 is driven to rotate on the inner wall of the fitting ring 6 to increase the stability of the support ring 4 during the rotation process. As the support ring 4 rotates on the outside of the filter element body 3, it drives the multiple scraping plates 5 on its inner wall to the filter element The outer side of the body 3 is scraped, and the cleaning liquid is transported downward by using the output hole 29, thereby increasing the scraping and cleaning effect, thereby improving the use effect of the cleaning device, and improving the filtering effect of the filter element body 3.

[0047] Step 2: When cleaning the outside of the filter element body 3, since one side of the collecting filter frame 10 is installed between the counterweight ring 8 and the other side is installed between the fitting ring 6, the collecting filter frame 10 filters and collects the waste water and impurities cleaned from the outside of the filter element body 3, thereby reducing the blockage of the sewage pipe of the water delivery cylinder 1 caused by excessive impurities;

[0048] Step 3: When it is necessary to clean the collection filter frame 10 and maintain the cleaning assembly, first pull the top cover 2 upwards, and drive the support ring 4 to move upwards, while driving the multiple rubber convex balls 20 to gradually detach from the lower side of the inner wall of the water delivery cylinder 1, so that the fitting ring 6 slides upward along the inner wall of the water delivery cylinder 1. At this time, the plug-in portion 27 at the bottom of the counterweight ring 8 will simultaneously detach from the plug-in groove 28, and drive the counterweight ring 8 to slide upward along the outer side of the filter element body 3, thereby facilitating the removal of the collection filter frame 10, and driving the multiple scraping plates 5 to detach from the water delivery cylinder 1, thereby facilitating the cleaning of the collection filter frame 10 while maintaining the cleaning assembly, thereby improving the cleaning efficiency of the cleaning device. The use effect of the device is that after cleaning and maintenance is completed, the counterweight ring 8 is sleeved on the outside of the filter element body 3, and the collection filter frame 10 is inserted into the gap between the water delivery cylinder 1 and the filter element body 3, and then the top cover 2 is pushed downward to drive the fitting ring 6 to reset along the inner wall of the water delivery cylinder 1, and drive the plug-in portion 27 at the bottom of the counterweight ring 8 to insert into the inner wall of the plug-in groove 28. At this time, the multiple rubber convex balls 20 on the outside of the fitting ring 6 will be engaged and deformed with the inner wall of the water delivery cylinder 1, increasing the stability between the fitting ring 6 and the water delivery cylinder 1, and improving the stability of the support ring 4 during the rotation process. Finally, the top cover 2 is reset to complete the cleaning and maintenance operation.
