[0002] As people's quality of life improves, they are paying more and more attention to water safety, and the use of filters in water filtration is becoming increasingly widespread. One widely used filter is in water purifiers, such as reverse osmosis water purifiers. As a crucial component of a water purifier, the filter element has a significant impact on the entire system.

[0003] During long-term use, a water purifier will breed bacteria and cause microbial contamination, especially in the filter element that has been standing for a long time. Bacteria will multiply in large numbers and ammonia nitrogen will exceed the standard, causing organic and microbial contamination of the filter element, resulting in a shortened lifespan and easy generation of odor.

[0004] Existing technologies achieve sterilization by injecting bactericidal substances into or outside the filter element. However, this sterilization technology can suffer from poor release of the bactericidal substance, making it difficult to effectively address the odor caused by excessive bacterial growth. Furthermore, the bactericidal substance remains in the water treatment unit, posing a risk to water quality. Utility Model Content

[0038] like Figures 1 to 6 As shown, the present invention provides a water purification system, including a reverse osmosis filter element 1, a raw water pipeline, a pure water pipeline, and a wastewater pipeline 30. The reverse osmosis filter element 1 is provided with a raw water inlet, a pure water outlet, and a wastewater outlet. The raw water pipeline is connected to the raw water inlet, the pure water pipeline is connected to the pure water outlet, and the wastewater pipeline 30 is connected to the wastewater outlet. Raw water enters the reverse osmosis filter element 1 through the raw water pipeline and the raw water inlet for filtration. Pure water formed after filtration by the reverse osmosis filter element 1 flows out through the pure water outlet and the pure water pipeline. Wastewater formed after filtration by the reverse osmosis filter element 1 flows out through the wastewater outlet and the wastewater pipeline 30.

[0039] The water purification system also includes a pre-filter cartridge 3. The raw water pipeline includes a first raw water pipeline 11 and a second raw water pipeline 12. The first raw water pipeline 11 is connected to the inlet of the pre-filter cartridge 3. One end of the second raw water pipeline 12 is connected to the outlet of the pre-filter cartridge 3 and the other end is connected to the raw water inlet of the reverse osmosis filter cartridge 1. The pre-filter cartridge 3 generally includes a polypropylene fiber filter layer and an activated carbon filter layer, which can filter out large particles and some colored impurities in the raw water, preventing impurities from damaging the reverse osmosis filter cartridge 1 and effectively extending the service life of the water purification system.

[0040] The water purification system also includes a booster pump 4, which is installed in the first raw water pipeline 11 or the second raw water pipeline 12. The booster pump 4 provides power for the water flow, allowing the raw water to be filtered and purified under pressure through the reverse osmosis filter element 1. In this embodiment, the booster pump 4 is installed in the second raw water pipeline 12, that is, downstream of the pre-filter element 3. This prevents impurities in the raw water from damaging the booster pump 4, further extending the service life of the water purification system.

[0041] To control the water flow, the water purification system also includes an inlet valve 5, which is located in either the first raw water pipeline 11 or the second raw water pipeline 12. The inlet valve 5 can be a solenoid valve. In this embodiment, the inlet valve 5 is located in the first raw water pipeline 11. Alternatively, the inlet valve 5 can be located in the second raw water pipeline 12, downstream of the pre-filter 3. This prevents impurities in the raw water from damaging the solenoid valve, further extending the service life of the water purification system.

[0042] The water purification system also includes a post-filter element 6. The pure water pipeline includes a first pure water pipeline 21 and a second pure water pipeline 22. One end of the first pure water pipeline 21 is connected to the pure water outlet of the reverse osmosis filter element 1, and the other end is connected to the inlet of the post-filter element 6. The second pure water pipeline 22 is connected to the outlet of the post-filter element 6. The post-filter element 6 is generally a granular carbon filter layer, which can further filter the pure water flowing through, filter out particulate impurities and some colored impurities in the pure water, and further improve the water quality.

[0043] Optionally, the pre-filter element 3 and the post-filter element 6 may be provided separately, or may form a composite filter element.

[0044] To prevent backflow of pure water, a first one-way valve 7 and a high-pressure switch 8 are provided on the second pure water pipeline 22. The first one-way valve 7 is connected in series between the high-pressure switch 8 and the outlet of the post-filter element 6. The first one-way valve 7 is configured to allow water to flow in one direction, in the direction of pure water outflow. The provision of the first one-way valve 7 and the high-pressure switch 8 facilitates pure water outflow and prevents backflow of pure water.

[0045] In order to prevent wastewater from flowing back, a second one-way valve 9 is provided on the wastewater pipeline 30. The second one-way valve 9 is configured to allow water to flow in one direction along the wastewater outlet direction.

[0046] The water purification system provided by the present invention also includes a negative ion generator 2. During operation, the negative ion generator 2 can rapidly emit a large number of electrons (e-). When these electrons enter the water purification system, they are captured by oxygen molecules (O2) in the system, thereby generating oxygen negative ions. The oxygen negative ions generate endogenous voltage through electronic transitions, which can damage protein-based biofilms, effectively inhibit bacterial regeneration, reduce biological contamination, and extend the service life of the water purification system.

[0047] In some embodiments, the negative ion generator 2 is disposed in a raw water pipeline or a pure water pipeline.

[0048] Optionally, when the negative ion generator 2 is provided in the raw water pipeline, the negative ion generator 2 can be provided in the second raw water pipeline 12 and located downstream of the booster pump 4, referring to Figure 1 The closer to the raw water side in the raw water pipeline, the more bacteria there are. As the raw water flows and settles along the raw water pipeline and is filtered by the pre-filter, the farther away from the raw water side, the less bacteria there are. By setting the negative ion generator 2 between the booster pump 4 and the reverse osmosis filter element 1, that is, setting the negative ion generator 2 at the position farthest from the raw water side in the raw water pipeline, the number of times the negative ion generator is started can be reduced, electric energy can be saved, and the reverse osmosis filter element 1 can be effectively sterilized and protected. Alternatively, the negative ion generator 2 can also be set in the second raw water pipeline 12 and located upstream of the booster pump 4, refer to Figure 2 Compared with the location downstream of the booster pump 4, this location is closer to the raw water side, the amount of bacteria will be greater, and the number of activations of the negative ion generator 2 will be greater accordingly. At this time, the negative ion generator 2 can effectively sterilize the booster pump 4, and at the same time, it also has a certain protective effect on the reverse osmosis filter element 1 located downstream of the booster pump 4. Alternatively, the negative ion generator 2 can also be set in the first raw water pipeline 11, refer to Figure 3 This position is closest to the raw water side, where the bacteria are the largest. Accordingly, the negative ion generator 2 is started more frequently and consumes more power. At this time, the negative ion generator 2 can effectively sterilize and protect the pre-filter 2, and at the same time, it also has a certain protective effect on the booster pump 4 and reverse osmosis filter 1 located downstream of the pre-filter 3.

[0049] Optionally, when the negative ion generator 2 is provided in the pure water pipeline, the negative ion generator 2 can be provided in the first pure water pipeline 21, referring to Figure 4By placing the negative ion generator in the first pure water pipeline, the post-filter element 6 can be effectively sterilized and protected, and the pure water quality can be more effectively improved, and the taste of the pure water can be optimized. Alternatively, the negative ion generator 2 can also be placed in the second pure water pipeline 22, refer to Figure 5 This position can effectively improve the quality of pure water and optimize the taste of pure water.

[0050] Reference Figure 6 In some embodiments, the pure water pipeline further includes a pure water return line 40. One end of the pure water return line 40 is connected to the raw water pipeline, and the other end is connected to the first pure water pipeline 21. Pure water in the first pure water pipeline 21 can flow back to the raw water pipeline through the pure water return line 40. When the water purification system is shut down and before restarting, the pure water return line 40 is controlled to circulate water, replacing all the water in the reverse osmosis filter element 1 with pure water, ensuring that pure water is available to the user upon startup.

[0051] Optionally, the negative ion generator 2 can be set on the pure water return pipe 40. In this position, only when the water purification system is shut down, the negative ion generator 2 can sterilize the booster pump 4 and the reverse osmosis filter element 1, which can not only sterilize and protect the booster pump 4 and the reverse osmosis filter element 1, but also improve the pure water quality of the user when the system is just turned on.

[0052] Reference Figure 6 The water purification system also includes a third one-way valve 10, which is installed on the pure water return line 40. This valve is configured to allow water to flow in one direction, from the pure water line to the raw water line. This prevents water in the raw water line from flowing into the pure water line through the pure water return line 40.

[0053] The present invention also provides a water purifier comprising the above-mentioned water purification system. By adopting the above-mentioned water purification system, bacterial regeneration can be effectively inhibited, biological contamination can be reduced, and the service life of the water purifier can be extended.

[0054] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
