The invention discloses a one-end-inlet high-efficiency water-saving
reverse osmosis membrane
assembly which comprises an upper end cover, a lower end cover, a central tube, a
reverse osmosis membrane, a sealing membrane, a sealing
adhesive tape, a sealing
adhesive, a seal ring 1 and a seal ring 2, wherein the
reverse osmosis membrane is wound on the central tube; the sealing membrane is wound outside the reverse
osmosis membrane; the upper end cover is covered on the upper end of the central tube which is wound by the reverse
osmosis membrane and sealing membrane, and sealed by the sealing
adhesive; the lower end cover is covered on the lower end of the central tube which is wound by the reverse
osmosis membrane and sealing membrane; and the gap between the lower end cover and reverse osmosis membrane is sealed by the sealing adhesive tape. The proportion of the
discharge amount of the filtered pure water outlet to the
raw water flowing into the membrane component can reach 1:2, thereby enhancing the water purification efficiency and performing the water-saving function. The reverse osmosis membrane
assembly is simple in structure, lowers the cost of the product, and enhances the production
assembly efficiency. The structure is simplified, thereby enhancing the sealing effect among various waterways, and reducing the possibility of the water mixing phenomenon in the prior art.
