[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides a reverse osmosis treatment device for drinking water processing, including a filter 1, a controller 2, a water treatment structure, and a high-pressure pump 3. The inlet end of the high-pressure pump 3 is connected to the filter 1, and the outlet end of the high-pressure pump 3 is connected to the inlet end of the water treatment structure. The water treatment structure includes a reverse osmosis component, which includes a housing 4. A partition 21 is provided in the middle of the inner cavity, dividing the inner cavity of the housing 4 into two receiving cavities 14, which are adapted to the reverse osmosis membrane. A sealing cap 12 is provided at one end of the receiving cavity 14, and an inlet screen 22 is fixedly connected to the inner side of the sealing cap 12. The inlet screen 22 has a hollow structure. A U-shaped groove 19 is provided at one end of the housing 4, and an inlet hole 5 is provided at the top of one end of the receiving cavity. The inner cavity of the inlet hole 5 communicates with the inner cavity of the U-shaped groove 19, and an inlet pipe 7 is fixedly connected to the middle of the U-shaped groove 19. A ball valve 6 is provided at the end of the U-shaped channel 2 19. The ball valve 6 is located on the side of the liquid inlet 5 near the water inlet pipe 7. Through the setting of the ball valve 6, the staff can control the opening and closing of the liquid inlet 5.

[0023] A one-way valve 17 is fixedly connected to the middle of the other end of the receiving cavity 14. A pure water pipe 10 is provided in the middle of the end of the outer shell 4 away from the sealing cover 12. The other end of the one-way valve 17 is connected to the pure water pipe 10. Through the setting of the one-way valve 17, the water treated by reverse osmosis can enter the pure water pipe 10 through the one-way valve 17 and be discharged through the pure water pipe 10. A flow meter 20 is provided on one side of the pure water pipe 10. The flow meter 20 can detect the flow rate of the treated water in real time. Based on the detection result, it can be determined whether the reverse osmosis membrane needs to be replaced.

[0024] The distance between the side of the inlet hole 5 away from the water inlet pipe 7 and the end of the outer casing 4 away from the pure water pipe 10 is greater than the thickness of the sealing cap 12, but less than the sum of the thicknesses of the inlet mesh tray 22 and the sealing cap 12. With this arrangement, when the sealing cap 12 is installed in the receiving cavity 14, the inlet hole 5 contacts the inlet mesh tray 22, and the water in the U-shaped groove 19 can enter the inner cavity of the inlet mesh tray 22 along the inlet hole 5. When the device is in use, the water in the inlet mesh tray 22 can enter the reverse osmosis membrane, and the reverse osmosis membrane can treat the water.

[0025] A connecting groove 15 is provided on the outer ring of the other end of the receiving cavity 14, and concentrated water can enter the inner cavity of the connecting groove 15. A U-shaped groove 18 is provided on the end of the outer shell 4 near the one-way valve 17. One-way valve 2 16 is fixedly connected to the end of the U-shaped groove 18, and the other end of the one-way valve 2 16 extends into the inner cavity of the connecting groove 15. A concentrated water discharge pipe 8 is fixedly connected to the middle of the U-shaped groove 18. The concentrated water produced by reverse osmosis can enter the concentrated water discharge pipe 8 through the connecting groove 15, the one-way valve 2 16 and the U-shaped groove 18.

[0026] As described above, when the reverse osmosis module is in use, the water to be treated can enter the receiving cavity through the inlet pipe 7, U-shaped groove 19, liquid inlet hole 5 and liquid inlet mesh 22. The pure water produced after the reverse osmosis membrane treats the water enters the pure water pipe 10 through the one-way valve 17 and is discharged through the pure water pipe 10. The concentrated water produced can enter the inner cavity of the concentrated water discharge pipe 8 through the connecting groove 15, one-way valve 16 and U-shaped groove 18 and is discharged through the concentrated water discharge pipe 8.

[0027] When the device is in use, the number of reverse osmosis components in the water treatment structure can be set according to the requirements. When there are multiple reverse osmosis components, the concentrate discharge pipe 8 near the outlet of the high-pressure pump 3 in two adjacent reverse osmosis components is connected to the inlet pipe 7 in the adjacent reverse osmosis component. With this setting, two adjacent reverse osmosis components can be connected together, and the water can undergo multiple reverse osmosis treatments.

[0028] A drain pump 11 is installed at the bottom of the outer casing 4, and a drain hole 13 is provided at the bottom of the receiving cavity 14. The inlet end of the drain pump 11 is connected to the drain hole 13 through a pipe, and the outlet end of the drain pump 11 is connected to the concentrate discharge pipe 8 through a return pipe 9. One end of the return pipe 9 is equipped with a one-way valve. A guide groove is provided at the bottom of the inner cavity of the receiving cavity 14, and the drain hole 13 is located at the bottom of the guide groove. With the drain pump 11 installed, the drain pump 11 can draw out the liquid in the receiving cavity and discharge the drawn water into the concentrate discharge pipe 8, thus preventing water accumulation in the receiving cavity 14.

[0029] Controller 2 can control the electrical components within the device.

[0030] As described above, when the device is in use, the reverse osmosis component can simultaneously accommodate two reverse osmosis membranes, and the two reverse osmosis membranes can operate in independent environments. This allows the device to continue operating even when the reverse osmosis membranes are replaced, ensuring the device's efficiency and improving the processing efficiency of drinking water.

[0031] In summary: When the reverse osmosis treatment device for drinking water processing is in use, the high-pressure pump 3 operates, and the water for drinking water processing is pumped into the inner cavity of the inlet pipe 7 after being filtered by the filter 1. The water in the inlet pipe 7 enters the receiving cavity 14 through the U-shaped groove 19, the liquid inlet hole 5, and the liquid inlet mesh 22. The reverse osmosis membrane placed in the receiving cavity 14 treats the water, and the filtered water produced after treatment enters the inner cavity of the pure water pipe 10 through the one-way valve 17 and is discharged through the pure water pipe 10. The concentrated water produced during the treatment process enters the inner cavity of the concentrated water discharge pipe 8 through the connecting groove 15, the one-way valve 16, and the U-shaped groove 18. If there are multiple reverse osmosis components in the water treatment structure, the concentrated water produced after one reverse osmosis treatment enters the inlet pipe 7 of another adjacent reverse osmosis component, and the other reverse osmosis component can continue to treat the concentrated water, realizing multiple water treatments. When the reverse osmosis membrane needs to be replaced, the operator installs the new reverse osmosis membrane in another receiving cavity 14 of the outer casing 4. The operator then adjusts the ball valve 6 to connect the U-shaped groove 19 with the inner cavity of the other receiving cavity 14, allowing the new reverse osmosis membrane to operate. Alternatively, the operator can adjust the ball valve 6 to disconnect the receiving cavity 14 from the inner cavity of the U-shaped groove 19, allowing the operator to replace the reverse osmosis membrane. During the replacement process, the device can continue to operate, ensuring its efficiency and thus improving the processing efficiency of drinking water.
