Abstract

The present invention relates to the field of RO filter technology, and more particularly to a waterway system of an RO filter comprising an outer cylinder, an RO membrane, a central tube of the RO membrane, and an inner central tube of the RO membrane. The inner central tube of the RO membrane is mounted inside the central tube of the RO membrane, the central tube of the RO membrane is mounted inside the RO membrane, and the RO membrane is mounted inside the outer cylinder. A water inlet, a purified water port, and a wastewater port are installed at the bottom of the outer cylinder, and valve components are respectively mounted inside the water inlet, purified water port, and wastewater port. A first waterway route is formed inside the inner central tube of the RO membrane, and the water inlet and the first waterway route are in communication. A second waterway route is formed between the outer wall of the RO membrane and the inner wall of the outer cylinder, and the purified water port is in communication with the second waterway route. A third waterway route is formed between the outer wall of the inner central tube of the RO membrane and the inner wall of the RO membrane central tube, and the third waterway route is connected to the second waterway route. By using a double-layer central tube waterway structure that does not restrict the waterway direction of the water inlet, the RO membrane ensures that a large amount of pure water is retained within the waterway system of the RO filter, thereby preventing the phenomenon of increased TDS from occurring.

Description

Waterway System with RO Filter Element The present invention relates to the field of RO filter technology, in particular to a water channel system of an RO filter. The invention disclosed in Publication No. CN218507603U discloses an RO filter comprising a filter cylinder, an RO membrane, a water shut-off valve, a bottom cover, a U-shaped decorative cover, and a handle. The RO membrane is installed by inserting it inside the filter cylinder, and a wastewater port, a purified water port, and a water inlet are sequentially opened at one end of the filter cylinder, and a water shut-off valve is installed inside the wastewater port and the purified water port. The water shut-off valve includes a valve core, a valve seat, a return spring, a valve core sealing ring, and a valve seat sealing ring. The valve core sealing ring is installed as a sleeve at the end of the valve core, and the valve seat sealing ring is installed as a sleeve around the valve seat. The drain pipe of the RO membrane is connected to the purified water port, and the drain port and the water inlet are each connected to the inner chamber of the filter cylinder. The defect of the RO filter is that the RO membrane has a single-layer central tube channel structure, which restricts the direction of the water inlet. As a result, a large amount of raw water and mixed wastewater flow from the outer wall of the RO membrane into the interior of the membrane body and accumulate, causing the water in the first cup to be secondary neutralized during use, leading to increased TDS or odors, and thus making it impossible to ensure the stability of pure water quality. Therefore, there is room for improvement in conventional technology. Figure 1 is an exploded view showing the overall structure of the present invention. FIG. 2 is a cross-sectional view showing the overall structure of the present invention. Figure 3 is an enlarged view showing location A of Figure 2. Figure 4 is an enlarged view showing position B of Figure 2. Figure 5 is a schematic diagram showing the baffle at the end of the central tube of the RO membrane. FIG. 6 is a schematic diagram showing the first waterway direction of the present invention. FIG. 7 is a schematic diagram showing the second waterway direction of the present invention. FIG. 8 is a schematic diagram showing the assembly of the RO membrane inner central tube and the RO membrane central tube of the present invention. Hereinafter, the technical solution of the present invention will be described by combining the attached drawings and embodiments. As illustrated in FIGS. 1 to 8, the waterway system of the RO filter according to the present invention comprises an outer cylinder (7), an RO membrane (8), an RO membrane central tube (9), and an RO membrane inner central tube (11). The RO membrane inner central tube (11) is mounted inside the RO membrane central tube (9), the RO membrane central tube (9) is mounted inside the RO membrane (8), and the RO membrane (8) is mounted inside the outer cylinder (7). A water inlet (31), a purified water outlet (32), and a wastewater outlet (33) are installed at the bottom of the outer cylinder (7), and valve components are each mounted inside the water inlet (31), the purified water outlet (32), and the wastewater outlet (33). A first waterway route (21) is formed inside the RO membrane inner central tube (11), and the water inlet (31) and the first waterway route (21) are connected. A second waterway route (22) is formed between the outer wall of the RO membrane (8) and the inner wall of the outer cylinder (7), and the water purification port (32) is connected to the second waterway route (22). A third waterway route (23) is formed between the outer wall of the inner central tube (11) of the RO membrane and the inner wall of the central tube (9) of the RO membrane, and the third waterway route (23) is connected to the second waterway route (22). When installed in this way, the RO membrane (8) uses a double-layer central tube waterway structure so as not to restrict the direction of the water inlet, and water flows in from the inner central tube of the RO membrane or the wastewater port. By reducing the volume of the water inlet route, a large amount of pure water is maintained inside the waterway system of the RO filter, thereby preventing the phenomenon of TDS increasing and ensuring the stability of the pure water quality. More specifically, according to the RO membrane (8) which is forward osmosis and reverse osmosis, there are two modes in the waterway. First waterway: Water flows into the first waterway route (21) through the water inlet (31), flows into the third waterway route (23) after passing through the RO membrane (8), and circulates while flowing back from the third waterway route (23) to the second waterway route (22), and purified water is discharged from the purified water outlet (32), and wastewater is discharged from the wastewater outlet (33). Second waterway: Water flo
