Description

Technical Field

[0001] This utility model relates to the field of high-efficiency reverse osmosis water purification technology, and in particular to a high-efficiency reverse osmosis water purification device. Background Technology

[0002] High-efficiency reverse osmosis water purification equipment is based on reverse osmosis membrane separation technology. Through optimized equipment structure design, it achieves efficient filtration, convenient maintenance, and stable operation. Using reverse osmosis technology as its core, it applies pressure greater than the osmotic pressure to the raw water. Utilizing the selective permeability of the reverse osmosis membrane (pore size approximately 0.0001 microns), it traps impurities such as inorganic salts, heavy metals, organic matter, bacteria, and viruses, allowing only water molecules to pass through, thus producing purified water that meets specific water quality standards.

[0003] Currently, traditional water purification equipment typically uses screws to securely fix the filter element and filtration structure. The screws generate a large axial force through the thread engagement, which can firmly fix the filter element, sealing plate and other components. Especially in high-pressure water flow environments, the components are not easily loosened due to vibration or impact, thus ensuring the stability of the filtration structure.

[0004] While screw fastening provides high strength, it requires screwdrivers, wrenches, and other tools for tightening or loosening the filter cartridge, making the process cumbersome, especially in scenarios requiring frequent maintenance and filter replacement. This significantly increases labor and time costs. Furthermore, screw holes penetrate the equipment casing or filter cartridge support, increasing sealing difficulty and requiring additional sealing rings. Improper installation or aging of the sealing rings can easily lead to leaks. Additionally, too many screws increase the complexity and weight of equipment assembly. Therefore, this paper proposes a high-efficiency reverse osmosis water purification device to address these issues. Utility Model Content

Mounting nuts 32 are located on the sides of both the connecting circular plate 10 and the fixed circular plate 14, with two mounting nuts 32 respectively located at both ends of the mounting rod 31. The mounting rod 31 passes through the connecting circular plate 10 and the fixed circular plate 14 and is fixed by the mounting nuts 32 at both ends, forming a longitudinal support structure. The limiting plate 12 is aligned with the connecting base plate 30 via a limiting ring block 24, ensuring that the filter element 13 is installed vertically and reliably sealed.

[0043] Reference Figure 1 , Figure 2 and Figure 6 The exhaust assembly includes a filter cotton 25, which is disposed inside the housing 5. A venting block 26 is disposed inside the housing 5. Threads are provided on the outer side of the end of the housing 5, and a mounting block 27 is threadedly connected to the inner side of the end of the housing 5. The venting block 26 and the filter cotton 25 cooperate to allow internal air to be discharged through the exhaust channel inside the venting block 26 when the equipment is started, while the filter cotton 25 filters impurities from the air. The exhaust assembly also includes a cover 6, which is disposed outside the housing 5. A filter plate 28 is fixedly connected to the inner side of the cover 6. Two sealing rings 29 are provided between the housing 5 and the venting block 26, and a sealing ring 29 is also provided on the inner side of the end of the mounting block 27. Two sealing rings 29 are also provided between the multiple fixed circular plates 14 and the multiple connecting base plates 30. The housing 5 and the mounting block 27 are connected by threads, and the sealing rings 29 prevent water leakage. The filter plate 28 inside the cover 6 further filters the exhaust gas, ensuring smooth gas discharge and preventing water contamination.

[0044] Reference Figure 1 , Figure 2 and Figure 7 The inner side of the outer casing 1 has an inlet 7 and an outlet 8. The inlet 7 is located near the filter element 13, and water enters the device through the inlet 7 on the side of the outer casing 1 and flows through the filter element 13. The outlet 8 is located at the bottom of the fixed circular plate 14. A semi-circular water collection hopper 15 is fixedly connected to the bottom of the outer casing 1, and an outlet pipe 9 is located inside the semi-circular water collection hopper 15, with its end located inside the outer casing 1. The purified water flows into the semi-circular water collection hopper 15 through the outlet 8 at the bottom of the fixed circular plate 14 and is finally discharged through the outlet pipe 9. Connecting blocks 2 are located on the outer sides of the two arc-shaped locking blocks 4, and a rotating handle 3 is fixedly connected to the inner side of the connecting blocks 2. By rotating the rotating handle 3, the sealing plate 21 can be installed and removed with one hand without tools, improving maintenance efficiency.

[0045] Working principle: First, water enters the equipment through the inlet 7 on the side of the outer casing 1, and flows through the filter element 13 area. The filter element 13 is installed between the limiting plate 12 and the connecting base plate 30, and can be quickly installed and removed by snapping the filter assembly, thus initially filtering large particulate impurities in the water, such as silt and suspended solids.

[0046] After preliminary filtration, the water flows into the reverse osmosis membrane assembly between the connecting circular plate 10 and the fixed circular plate 14. After entering through the inlet 7, the water is pretreated by the filter element 13, and then enters the outside of the reverse osmosis membrane through the through holes of the connecting circular plate 10. Under pressure, it permeates to the inside of the membrane and finally converges at the outlet 8 at the bottom of the fixed circular plate 14. The water is discharged from the outlet 8 and finally flows into the semi-circular water collection hopper 15. The purified water is then discharged from the equipment through the outlet pipe 9 for user use.

[0047] The sealing plate 21 is engaged with the outer shell 1 via the arc-shaped locking block 4, achieving sealing and disassembly of the side of the equipment. Rotating the rotating handle 3 causes the connecting block 2 to rotate, and the arc-shaped locking block 4 slides along the limiting block 17 through the elliptical locking groove 22 of the connecting plate 16, so that the locking block 19 is embedded into the arc-shaped locking groove of the outer shell 11, completing the locking or unlocking.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
