Description

Technical Field

[0001] The utility model relates to the technical field of water purification equipment, in particular to a reverse osmosis filter element and a water purifier capable of adjusting the TDS value of the effluent. Background Art

[0002] The existing water purification technologies are mainly used in the field of direct drinking water. Ultrafiltration technology is mainly used to obtain mineral water, or reverse osmosis technology is used to obtain pure water. There are certain defects in the water bodies obtained by these two technologies; for the mineral water obtained by ultrafiltration technology, since mineral elements cannot be removed, problems such as kettle scaling and dry taste will occur. In some areas with high water hardness, long-term drinking may even cause diseases such as kidney stones; the pure water obtained by reverse osmosis technology has extremely low mineral ion content. Although there is no water scale after heating, long-term drinking is likely to lead to insufficient intake of human mineral elements and diseases such as calcium deficiency and osteoporosis.

[0003] That is to say, for the water purified by the existing water purification equipment, its TDS value (i.e., total dissolved solids, which means how many milligrams of dissolved solids are dissolved in one liter of water) only has two situations: high and low. In terms of human health, the healthiest water should contain an appropriate amount of mineral elements, rather than too much or too little. People with different physical conditions have different requirements for mineral elements in water. Currently, the existing water purification equipment cannot flexibly change the mineral content in the effluent, that is, the TDS value. Therefore, it cannot meet the needs of different regions and different populations. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a reverse osmosis filter element and a water purifier capable of adjusting the TDS value of the effluent in view of the above-mentioned deficiencies of the existing technologies. The TDS value of the effluent can be adjusted, so as to meet the needs of different regions and different populations, and the structure is simple and easy to implement.

The water purification control valve is used to control the opening or closing of the mixing water pipe.

[0007] Further, a throttling orifice is provided in the purified water regulating valve. When the purified water regulating valve is powered on, the throttling orifice opens, and the raw water conveyed by the water inlet pipe flows from the throttling orifice to the water outlet pipe. When the purified water regulating valve is powered off, the throttling orifice closes.

[0008] Further, the throttling orifice is a round hole, and the diameter range of the throttling orifice is 0.3 mm to 1.0 mm.

[0009] Further, the reverse osmosis filter element further includes a concentrated water area provided in the filter bottle and a concentrated water pipe communicated with the concentrated water area.

The pure water area is formed inside the central pipe, the raw water area is formed in the reverse osmosis membrane, and the concentrated water area is formed between the reverse osmosis membrane and the inner wall of the bottle body.

[0012] Further, an inlet water channel communicating the raw water area with the outside, an outlet water channel communicating the pure water area with the outside, and a concentrated water channel communicating the concentrated water area with the outside are provided in the end cap. The water inlet pipe is communicated with the inlet water channel, the water outlet pipe is communicated with the outlet water channel, and the concentrated water pipe is communicated with the concentrated water channel.

[0013] Further, a first water isolation rib extending from the top of the central pipe to the end cap and a second water isolation rib extending from the top of the reverse osmosis membrane to the end cap are further provided in the bottle body. The first water isolation rib is used for separating the raw water area from the pure water area, and the second water isolation rib is used for separating the raw water area from the concentrated water area.

[0014] The present utility model further provides a water purifier, including the above-mentioned reverse osmosis filter element capable of adjusting the TDS value of the outlet water.

[0026] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figure 1 and Figure 2 A reverse osmosis filter element capable of adjusting the TDS value of the outlet water according to an embodiment of the present invention includes a filter bottle, a raw water area 11 provided in the filter bottle for storing raw water, and a pure water area 12 provided in the filter bottle for storing pure water; it further includes a water inlet pipe 3 communicating with the raw water area 11, a water outlet pipe 4 communicating with the pure water area 12, and a water purification adjustment component 6 connected in parallel between the water inlet pipe 3 and the water outlet pipe 4. The water inlet pipe 3 is used to input raw water into the raw water area 11, the water outlet pipe 4 is used to output the pure water in the pure water area 12, and the water purification adjustment component 6 is used to connect or close the water inlet pipe 3 and the water outlet pipe 4.

[0028] In the present application, the reverse osmosis filter element includes a filter bottle, in which a raw water area 11 and a pure water area 12 are provided, and further includes a water inlet pipe 3 and a water outlet pipe 4. The water inlet pipe 3 communicates with the raw water area 11, so as to convey the pre-filtered raw water to the raw water area 11 through the water inlet pipe 3. The water inlet pipe 3 first conveys the raw water to the raw water area 11 for storage. The raw water forms pure water after reverse osmosis filtration in the filter bottle and is conveyed to the pure water area 12. The pure water area 12 stores the pure water after reverse osmosis filtration, and then is connected to the pure water area 12 through the water outlet pipe 4, so that the water outlet pipe 4 outputs the pure water stored in the pure water area 12 for users to use, thereby realizing the function of outputting pure water by the reverse osmosis filter element.

[0029] Since in the present application, the reverse osmosis filter element further includes a water purification adjustment assembly 6, the water purification adjustment assembly 6 is connected in parallel between the water inlet pipe 3 and the water outlet pipe 4, and the connection or closing of the water inlet pipe 3 and the water outlet pipe 4 can be achieved through the water purification adjustment assembly 6. When the water purification adjustment assembly 6 closes the connection between the water inlet pipe 3 and the water outlet pipe 4, the water inlet pipe 3 conveys the pre-filtered raw water to the raw water area 11 for storage, so as to provide water source for the reverse osmosis filtration of the filter bottle.

[0030] When the water purification adjustment assembly 6 connects the water inlet pipe 3 and the water outlet pipe 4, the water inlet pipe 3 conveys the pre-filtered raw water to the water outlet pipe 4, and mixes it with the pure water output from the water outlet pipe 4, so as to adjust the TDS value of the water output by the reverse osmosis filter element, meet the needs of different regions and different people, and has a simple structure and is easy to implement.

[0031] Since the pure water output through the water outlet pipe 4 is for direct drinking by users, in order to ensure the health of users, in the present application, the raw water conveyed to the raw water area 11 or the water outlet pipe 4 through the water inlet pipe 3 has been pre-filtered through the previous process. However, the previous pre-filtration process is not reverse osmosis filtration, but ultrafiltration, which can basically filter out harmful substances such as bacteria, rust, and colloid in the water, while retaining the original trace mineral elements in the water. Thus, when the water inlet pipe 3 directly conveys the pre-filtered raw water to the water outlet pipe 4 and mixes it with the pure water conveyed by the water outlet pipe 4, it can not only adjust the TDS value of the water output by the reverse osmosis filter element, but also ensure the health of users.

[0032] In this embodiment, the water purification adjustment assembly 6 includes a mixing water pipe 61 that connects the water inlet pipe 3 and the water outlet pipe 4, and a water purification control valve 62 provided on the mixing water pipe 61. The water purification control valve 62 is used to control the opening or closing of the mixing water pipe 61. In the present application, the water purification adjustment assembly 6 includes a mixing water pipe 61 and a water purification control valve 62. One end of the mixing water pipe 61 is connected to the water inlet pipe 3, and the other end is connected to the water outlet pipe 4, so that the mixing water pipe 61 is connected in parallel between the water inlet pipe 3 and the water outlet pipe 4, and the connection between the water inlet pipe 3 and the water outlet pipe 4 is achieved through the mixing water pipe 61.

[0033] The water purification control valve 62 is provided on the mixing water pipe 61, and the opening or closing of the mixing water pipe 61 can be controlled through the water purification control valve 62. When the water purification control valve 62 is powered off, the mixing water pipe 61 is closed, so as to disconnect the water inlet pipe 3 and the water outlet pipe 4, and enable the water inlet pipe 3 to convey the pre-filtered raw water to the raw water area 11 for storage, so as to provide water source for the reverse osmosis filtration of the filter bottle.

[0034] When the water purification regulating valve 62 is powered on, the mixing water pipe 61 is opened, so that the water inlet pipe 3 is communicated with the water outlet pipe 4 through the mixing water pipe 61, and the raw water conveyed in the water inlet pipe 3 is conveyed to the water outlet pipe 4 through the mixing water pipe 61 and mixed with the pure water output in the water outlet pipe 4, thereby adjusting the TDS value of the water output from the reverse osmosis filter element to meet the needs of different regions and different people, and the structure is simple and easy to implement.

[0035] Specifically, in this embodiment, a throttle hole is provided in the water purification regulating valve 62, and the raw water in the mixing water pipe 61 flows out from the throttle hole when flowing through the water purification regulating valve 62. When the water purification regulating valve 62 is powered on, the throttle hole is opened, so that the raw water conveyed in the water inlet pipe 3 can flow out through the throttle hole and continue to flow in the mixing water pipe 61 towards the water outlet pipe 4, thereby realizing the mixing of the raw water and the pure water and adjusting the TDS value of the water output from the reverse osmosis filter element.

[0036] When the water purification regulating valve 62 is powered off, the throttle hole is closed, so that the raw water conveyed in the water inlet pipe 3 cannot flow out of the throttle hole, thereby cutting off the mixing water pipe 61, preventing the raw water from continuing to flow in the mixing water pipe 61 towards the water outlet pipe 4, and instead flowing towards the raw water area 11 to provide water source for the reverse osmosis filtration of the filter bottle.

[0037] In this application, the water inlet pipe 3 for conveying raw water to the filter bottle and the water outlet pipe 4 for outputting pure water from the filter bottle are usually round pipes. Therefore, further in this embodiment, the throttle hole can be set as a round hole, so that when the throttle hole is opened, the raw water conveyed through the water inlet pipe 3 can flow out of the throttle hole better and flow through the mixing water pipe 61 towards the water outlet pipe 4 to be mixed with the pure water in the water outlet pipe 4, adjusting the TDS value of the water output from the reverse osmosis filter element.

[0038] However, the raw water flowing out of the throttle hole and flowing through the mixing water pipe 61 towards the water outlet pipe 4 needs to be mixed with the pure water conveyed in the water outlet pipe 4 in a certain proportion to make the TDS value of the water output from the reverse osmosis filter element reach the preset requirement. Therefore, the diameter of the throttle hole cannot be too large or too small. In this embodiment, the diameter range of the throttle hole is preferably 0.3 mm to 1.0 mm. The specific diameter size of the throttle hole can be determined according to the actual production requirements.

[0039] In this embodiment, the reverse osmosis filter element further includes a concentrated water area 13 provided in the filter bottle and a concentrated water pipe 5 communicated with the concentrated water area 13. The concentrated water area 13 is used to store the concentrated water generated during filtration, and the concentrated water pipe 5 is used to output the concentrated water. Since the reverse osmosis filter element performs reverse osmosis filtration on the raw water, in this process, a part of the water is completely purified to form pure water, while another part of the water is concentrated, which contains a large amount of impurities and salts, forming concentrated water. If the concentrated water formed in the reverse osmosis filter element cannot be processed in time, it may cause excessive concentration of the concentrated water, resulting in blockage of the filter element or the water purifier and affecting the service life of the filter element and the water purifier.

[0040] Therefore, in the present application, the reverse osmosis filter element further includes a concentrated water area 13 and a concentrated water pipe 5. The concentrated water area 13 is arranged in the filter bottle. When the raw water stored in the raw water area 11 is subjected to reverse osmosis filtration in the filter bottle, a part of the water forms pure water, and the other part of the water forms concentrated water. The formed pure water is transported to the pure water area 12 for storage, and the formed concentrated water is transported to the concentrated water area 13 for storage. The concentrated water pipe 5 is communicated with the concentrated water area 13, so as to timely discharge the concentrated water stored in the concentrated water area 13 through the concentrated water pipe 5, thereby preventing the concentrated water from being overly compressed, resulting in the blockage of the filter element or the water purifier, and ensuring the service life of the filter element and the water purifier.

[0041] In this embodiment, the filter bottle includes a bottle body 1 and an end cap 2 arranged on the bottle body 1. The end cap 2 is used to seal the bottle body 1. The raw water area 11, the pure water area 12 and the concentrated water area 13 are all formed in the bottle body 1. The water inlet pipe 3, the water outlet pipe 4 and the concentrated water pipe 5 are all arranged on the end cap 2. In the present application, the filter bottle includes the bottle body 1 and the end cap 2. The raw water area 11, the pure water area 12 and the concentrated water area 13 are all formed in the bottle body 1. The end cap 2 seals the bottle body 1. The water inlet pipe 3, the water outlet pipe 4 and the concentrated water pipe 5 are all arranged on the end cap 2.

[0042] The water inlet pipe 3 arranged on the end cap 2 is communicated with the raw water area 11 arranged in the bottle body 1, so that the water inlet pipe 3 transports the pre-filtered raw water to the raw water area 11. The water inlet pipe 3 first transports the raw water to the raw water area 11 for storage. After the raw water undergoes reverse osmosis filtration in the bottle body 1, pure water and concentrated water are formed. The pure water is transported to the pure water area 12, and the pure water area 12 stores the pure water after reverse osmosis filtration; the concentrated water is transported to the concentrated water area 13, and the concentrated water area 13 stores the concentrated water formed by reverse osmosis filtration.

[0043] Finally, the water outlet pipe 4 arranged on the end cap 2 is communicated with the pure water area 12 arranged in the bottle body 1, so that the water outlet pipe 4 outputs the pure water stored in the pure water area 12 for the user to use, thereby realizing the function of outputting pure water of the reverse osmosis filter element; the concentrated water pipe 5 arranged on the end cap 2 is communicated with the concentrated water area 13 arranged in the bottle body 1, so that the concentrated water pipe 5 outputs the concentrated water stored in the concentrated water area 13, preventing the concentrated water from being overly compressed, resulting in the blockage of the filter element or the water purifier, and ensuring the service life of the filter element and the water purifier.

[0044] In this embodiment, the filter bottle further includes a central pipe 14 arranged in the bottle body 1 and a reverse osmosis membrane 15 arranged in the bottle body 1. The reverse osmosis membrane 15 surrounds the outside of the central pipe 14. The pure water area 12 is formed inside the central pipe 14. The raw water area 11 is formed in the reverse osmosis membrane 15. The concentrated water area 13 is formed between the reverse osmosis membrane 15 and the inner wall of the bottle body 1. In the present application, the filter bottle further includes the central pipe 14 and the reverse osmosis membrane 15. The central pipe 14 and the reverse osmosis membrane 15 are both arranged in the bottle body 1.

[0045] The central tube 14 is arranged in the middle of the bottle body 1, so as to form a pure water area 12 in the central tube 14; the reverse osmosis membrane 15 surrounds the outside of the central tube 14, so as to form a raw water area 11 in the reverse osmosis membrane 15, and a concentrated water area 13 is formed between the reverse osmosis membrane 15 and the inner wall of the bottle body 1. When the water inlet pipe 3 conveys the pre-filtered raw water to the raw water area 11, the reverse osmosis membrane 15 further performs reverse osmosis filtration on the raw water. During this process, a part of the water forms pure water, and another part of the water forms concentrated water. Among them, the pure water enters the pure water area 12 in the central tube 14 for storage, and the concentrated water enters the concentrated water area 13 between the reverse osmosis membrane 15 and the inner wall of the bottle body 1 for storage.

[0046] It can be foreseen that: a plurality of filter holes are provided on the pipe wall of the central tube 14. Inside the reverse osmosis membrane 15, the pure water filtered by the reverse osmosis membrane 15 can enter the pure water area 12 in the central tube 14 through the plurality of filter holes on the pipe wall of the central tube 14; outside the reverse osmosis membrane, the concentrated water formed by the filtration of the reverse osmosis membrane 15 flows into the concentrated water area 13 between the reverse osmosis membrane 15 and the inner wall of the bottle body 1.

[0047] In this embodiment, the end cap 2 is provided with a water inlet channel 21 communicating the raw water area 11 with the outside, a water outlet channel 22 communicating the pure water area 12 with the outside, and a concentrated water channel 23 communicating the concentrated water area 13 with the outside. The water inlet pipe 3 is communicated with the water inlet channel 21, the water outlet pipe 4 is communicated with the water outlet channel 22, and the concentrated water pipe 5 is communicated with the concentrated water channel 23. In this application, the end cap 2 is provided with a water inlet channel 21, a water outlet channel 22 and a concentrated water channel 23. When the end cap 2 closes the bottle body 1, the water inlet channel 21 communicates the raw water area 11 in the bottle body 1 with the outside, the water outlet channel 22 communicates the pure water area 12 in the bottle body 1 with the outside, and the concentrated water channel 23 communicates the concentrated water area 13 in the bottle body 1 with the outside.

[0048] A water inlet joint is provided at one end of the water inlet channel 21 away from the bottle body 1. Through the water inlet joint, the water inlet pipe 3 can be connected to the end cap 2, and through the water inlet channel 21, the water inlet pipe 3 is communicated with the raw water area 11 in the bottle body 1, so that the pre-filtered raw water can be conveyed to the raw water area 11 through the water inlet pipe 3 to provide a water source for the reverse osmosis filtration of the bottle body 1.

[0049] A water outlet joint is provided at one end of the water outlet channel 22 away from the bottle body 1. Through the water outlet joint, the water outlet pipe 4 can be connected to the end cap 2, and through the water outlet channel 22, the water outlet pipe 4 is communicated with the pure water area 12 in the bottle body 1, so that the pure water stored in the pure water area 12 can be output through the water outlet pipe 4 for direct drinking by users;

[0050] A concentrated water connector is provided at one end of the concentrated water channel 23 away from the bottle body 1. Through the concentrated water connector, the concentrated water pipe 5 can be connected to the end cap 2, and the concentrated water pipe 5 is communicated with the concentrated water area 13 in the bottle body 1 through the concentrated water channel 23. Thus, the concentrated water stored in the concentrated water area 13 can be discharged through the concentrated water pipe 5, preventing the concentrated water from being overly compressed, which may cause the filter element or the water purifier to be blocked, and ensuring the service life of the filter element and the water purifier.

[0051] In this embodiment, a first water isolation rib 16 extending from the top of the central pipe 14 to the end cap 2, and a second water isolation rib 17 extending from the top of the reverse osmosis membrane 15 to the end cap 2 are further provided in the bottle body 1. The first water isolation rib 16 is used to separate the raw water area 11 from the pure water area 12, and the second water isolation rib 17 is used to separate the raw water area 11 from the concentrated water area 13. As mentioned in the previous embodiment, the central pipe 14 is arranged in the middle of the bottle body 1, the pure water area 12 is formed in the central pipe 14, the reverse osmosis membrane 15 surrounds the outside of the central pipe 14, the raw water area 11 is formed in the reverse osmosis membrane 15, and the concentrated water area 13 is formed between the reverse osmosis membrane 15 and the inner wall of the bottle body 1. Therefore, in the bottle body 1, the raw water area 11 is located outside the pure water area 12, and the concentrated water area 13 is located outside the raw water area 11.

[0052] In this application, a first water isolation rib 16 is further provided in the bottle body 1. When the end cap 2 closes the bottle body 1, the first water isolation rib 16 extends from the top of the central pipe 14 to the end cap 2. Thus, the pure water area 12 is separated from the raw water area 11 located outside the pure water area 12 through the first water isolation rib 16, and the water outlet channel 22 on the end cap 2 extends into the bottle body 1 through the first water isolation rib 16. Furthermore, the pure water stored in the pure water area 12 passes through the area inside the first water isolation rib 16 and the water outlet channel 22 in sequence, and then is output from the water outlet pipe 4 for direct drinking by the user.

[0053] A second water isolation rib 17 is further provided in the bottle body 1. When the end cap 2 closes the bottle body 1, the second water isolation rib 17 extends from the top of the reverse osmosis membrane 15 to the end cap 2. Thus, the raw water area 11 is separated from the concentrated water area 13 located outside the raw water area 11 through the second water isolation rib 17, and the water inlet channel 21 and the concentrated water channel 23 on the end cap 2 extend into the bottle body 1 through the second water isolation rib 17. Furthermore, the raw water conveyed by the water inlet pipe 3 flows to the raw water area 11 after passing through the water inlet channel 21 and the area between the first water isolation rib 16 and the second water isolation rib 17 in sequence; the concentrated water stored in the concentrated water area 13 is output from the concentrated water pipe 5 after passing through the area between the second water isolation rib 17 and the inner wall of the bottle body 1 and the concentrated water channel 23 in sequence.
