[0028] VII. This water purification device using reverse osmosis membrane filter cartridges can collect pollutants as they deposit inside the funnel. It draws out high-concentration wastewater and pollutants from the reverse osmosis filter cartridge and funnel, and discharges them into the storage tank through a bend in the pipe. The wastewater can then be filtered by the filter screen, forming a cycle that facilitates subsequent reverse osmosis water purification. At the same time, the right-angle inlet pipe injects the water to be treated into the storage tank, where the filter screen performs preliminary filtration and pretreatment.

[0029] 8. This water purification device, which utilizes a reverse osmosis membrane filter assembly, applies an impact force to the impeller blades when the water impacts them. The rotating shaft causes the spherical ball and impeller blades to rotate together. Furthermore, the elastic connection of the supporting spring causes the striking ball to rotate as well. This striking ball then contacts the inner wall of the filter screen, causing it to vibrate and dislodge debris adhering to the screen. This facilitates water filtration and reduces the likelihood of clogging.

[0030] 9. This water purification device using reverse osmosis membrane filter cartridges uses a booster pump to draw pre-treated water from the storage tank and spray it into the inlet hopper, increasing the water pressure. This causes the semi-circular blades to be impacted by the water, and with the support of the bracket and the rotation of the rotating shaft, the rotating shaft drives the cleaning brush and scraper to rotate. The rotating cleaning brush brushes off the contaminants attached to the inner wall of the reverse osmosis filter cartridge, and the scraper scrapes off the contaminants deposited on the inner wall of the funnel as it rotates.

[0062] At this time, the reverse osmosis filter element 61 is conical, and the diameter of the conical reverse osmosis filter element 61 gradually increases from top to bottom, the water flows from the small end of the diameter and flows downward through the gradually increasing diameter, the flow passage cross-sectional area gradually expands, forming a "gradually expanding" flow, the water flow rate gradually decreases, and the static pressure increases, so that the water flow forms a low-speed brushing effect on the membrane inner wall, avoids mechanical damage of high-speed water flow to the reverse osmosis filter element 61, and improves the stripping capacity of pollutants by using static pressure, reducing the attachment of pollutants to the inner wall of the reverse osmosis filter element 61;

[0063] And the high concentration water is injected into the inside of the reverse osmosis filter core 61 at the middle of the clean water tank 1 through the high concentration water inlet 3, and under the action of the water pressure, the high concentration water penetrates into the inside of the clean water tank 1 through the reverse osmosis filter core 61, forming reverse osmosis, and the pollutants in the high concentration water are intercepted in the inside of the reverse osmosis filter core 61, so that the water body is purified;

[0064] And the reverse osmosis filter core 61 is designed as a cone shape, and the wall thickness of the reverse osmosis filter core 61 gradually increases from top to bottom, instead of being uniform from top to bottom as in the existing cylindrical shape, so that the high concentration water entering the inside of the reverse osmosis filter core 61 gradually undergoes reverse osmosis, and flows downward with the water body and the intercepted pollutants, so that there are more pollutants at the bottom of the reverse osmosis filter core 61, and the high concentration water is fully subjected to reverse osmosis in combination with the increased wall thickness at the bottom of the reverse osmosis filter core 61;

[0065] Meanwhile, the outer sleeve ring 63 is sleeved on the surface of the reverse osmosis filter core 61, and the inner sleeve ring 64 supports the inner wall of the reverse osmosis filter core 61, and the outer sleeve ring 63 and the inner sleeve ring 64 are connected through the support pull rod 65, so that the overall strength of the reverse osmosis filter core 61 is increased, and the reverse osmosis filter core 61 is not easy to break;

[0066] And the gas in the arched elastic membrane 662 enters the inside of the plugging capsule 661 through the first communication pipe 663 and the second communication pipe 664, so that the plugging capsule 661 expands, fills the gap between the inner sleeve ring 64 and the inner wall of the reverse osmosis filter core 61, and seals the connection between the support pull rod 65 and the reverse osmosis filter core 61 in time;

[0067] And the semicircular blade 74 is impacted by the water body, is supported by the support 71, and rotates under the rotation connection of the rotating shaft 72, so that the rotating shaft 72 drives the cleaning brush 75 and the scraping strip 76 to rotate, so that the cleaning brush 75 in rotation brushes off the pollutants attached to the inner wall of the reverse osmosis filter core 61, and the pollutants deposited on the inner wall of the funnel 62 can be scraped and cleaned by the rotation of the scraping strip 76;

[0068] At this time, the high concentration water is subjected to reverse osmosis purification by the reverse osmosis filter core 61, and the purified water body is discharged from the water outlet 4;

[0069] As the pollutants are deposited in the inside of the funnel 62, the pollutants can be gathered, the staff opens the pump body 5 to work, and the high concentration sewage and pollutants in the reverse osmosis filter core 61 and the funnel 62 are sucked out and discharged into the inside of the water storage tank 21 under the conveying of the elbow pipe 23, so that the sewage can be filtered by the filter screen 25, forming a cycle, so as to facilitate subsequent reverse osmosis water purification again.

[0070] Comparative example, based on the first embodiment: replace the sealing assembly 66 with a common sealing ring, and the rest of the structure remains unchanged;

[0071] Common sealing ring specifications:

[0072] Sealing ring material: nitrile rubber, fluororubber;

[0073] Cross-sectional size: 3.53mm, sealing ring is O-ring;

[0074] Installation gap: 0.1mm;

[0075] Pressure range: 0-1.6MPa.

[0076] Performance test report:

[0077] Sealing assembly 66 test data:

[0078]

[0079] Common sealing ring test data:

[0080]

[0081] Through the comparison of experimental data:

[0082] Common sealing ring: unable to adapt to pressure changes and size deviations, low reliability, easy to leak and rupture;

[0083] And the greater the pressure of the sealing assembly 66, the better the sealing effect, which can adapt to small size deviations and material thermal expansion and contraction, and is not prone to leakage and rupture;

[0084] At the same time, the working principle of the sealing assembly 66 is reliable: the working mechanism of the sealing assembly 66 is water pressure feedback type automatic sealing;

[0085] When the water pressure inside the reverse osmosis filter element 61 increases, the pressure directly acts on the arched elastic membrane 662, and the gas in the membrane is pressed into the plugging capsule 661 through the first communication pipe 663 and the second communication pipe 664, the capsule expands to fill the gap between the inner sleeve ring 64 and the inner wall of the filter element, forming a dynamic seal.

[0086] The advantages of this design are:

[0087] Self-adapting sealing: no need for manual intervention, the greater the pressure, the better the sealing effect;

[0088] Double protection: mechanical contact sealing and pressure enhancement effect;

[0089] Compensation ability: can adapt to small size deviations and material thermal expansion and contraction.

[0090] Material and structural reliability;

[0091] The hydrolysis-resistant and chlorine-resistant elastomer material is used, and the arched elastic film 662 provides good pressure response characteristics, the communication pipeline design ensures smooth gas flow, and the support rod 65 and the middle hole of the capsule body design avoid partial load.

[0092] Therefore, the sealing assembly 66 of the present application is superior to the sealing ring of the prior art.
