Based on market research and user feedback, the inventors found that existing water purifiers produce water with a relatively constant TDS value (total dissolved solids, primarily reflecting the concentration of calcium, magnesium, sodium, and potassium ions). Therefore, when users require purified water with different TDS values ​​to prepare or cook beverages with specific flavors, these existing water purifiers are insufficient to meet their needs. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a water purifier.

[0004] A water purifier according to an embodiment of the present invention includes a frame, and an inlet section, a pre-filter assembly, an ultrafiltration membrane module, an RO membrane module, a mixing valve, and a first outlet section, all disposed on the frame. The inlet section, the pre-filter assembly, the ultrafiltration membrane module, the mixing valve, and the first outlet section are sequentially connected. The RO membrane module is connected to the ultrafiltration membrane module and the mixing valve. Water flowing sequentially through the inlet section, the pre-filter assembly, and the ultrafiltration membrane module can partially pass through the RO membrane module and enter the mixing valve to mix with another portion that directly enters the mixing valve before being output through the first outlet section.

[0028] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0029] In the description of this utility model, the use of terms such as first, second, third, fourth, and fifth is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0030] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] In this utility model, unless otherwise explicitly defined, the terms "setting," "installing," and "connecting" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to a fixed connection, a detachable connection, or an integral molding; they can refer to a mechanical connection; they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] Reference Figures 1 to 4 This utility model discloses a water purifier, comprising a frame 100, and an inlet section 200, a pre-filter assembly 300, an ultrafiltration membrane module 400, an RO membrane module 500, a mixing valve 600, and a first outlet section 710, all disposed on the frame 100. The inlet section 200, pre-filter assembly 300, ultrafiltration membrane module 400, mixing valve 600, and first outlet section 710 are sequentially connected. The RO membrane module 500 is connected to the ultrafiltration membrane module 400 and the mixing valve 600. Water flowing sequentially through the inlet section 200, pre-filter assembly 300, and ultrafiltration membrane module 400 can partially pass through the RO membrane module 500 into the mixing valve 600, where it mixes with the remaining water directly entering the mixing valve 600 before being output through the first outlet section 710. This connection can be achieved through pipes.

[0033] It is understandable that, based on the above structure, referring to Figure 4 After water flows sequentially through the inlet section 200, the pre-filter assembly 300, and the ultrafiltration membrane module 400, it becomes mineral water and is divided into two paths. One path directly enters the mixing valve 600, while the other path is filtered into pure water by the RO membrane module 500 before entering the mixing valve 600. The two streams of water entering the mixing valve 600 are mixed (i.e., mineral water and pure water are mixed) and then output through the first outlet section 710.

[0034] Understandably, users can operate the mixing valve 600 to control the ratio of mineral water and pure water in the mixing of the two water streams, so as to obtain purified water with the corresponding TDS value from the first water outlet 710.

[0035] Understandably, the ultrafiltration membrane module 400 is an ultrafiltration membrane filter element, which can intercept bacteria and microorganisms in water through physical sieving principles, and can remove large molecular organic matter while retaining minerals beneficial to the human body; the RO membrane module 500 is an RO membrane filter element, which can achieve high-precision filtration to obtain pure water through nanopores; the pre-filter assembly 300 does not include the ultrafiltration membrane module 400 and the RO membrane module 500, and the pre-filter assembly 300 can perform preliminary filtration work such as removing particulate impurities and adsorbing organic matter.

[0036] Through the aforementioned structure, on the one hand, the water purifier of this application, through the design of the mixing valve 600, can mix low-TDS pure water that has undergone deep desalination by the RO membrane module 500 with high-TDS mineral water that has been filtered only by the ultrafiltration membrane module 400 and retains minerals. Users can adjust the opening of the mixing valve 600 to control the TDS value of the mixed water ultimately output from the first outlet 710, thereby obtaining purified water with different mineral concentrations. Therefore, it solves the problem of relatively constant and uniform TDS values ​​in existing water purifiers. Users can select the most suitable TDS value according to different uses (such as brewing tea / coffee, preparing milk powder / drinks, cooking specific dishes, direct drinking, etc.), significantly improving the taste and flavor compatibility of water in different scenarios. On the other hand, the entire system is integrated on the frame 100, optimizing the overall structural integration and facilitating user operation.

[0037] In this embodiment, refer to Figures 1 to 4 The frame 100 is provided with a second water outlet 720, and the RO membrane module 500 is connected to the second water outlet 720. Water that flows sequentially through the water inlet 200, the pre-filter assembly 300, the ultrafiltration membrane module 400, and the RO membrane module 500 can be output through the second water outlet 720.

[0038] The above structure enables the water purifier of this application to provide an independent high-purity pure water (low TDS value) output channel for user use.

[0039] In this embodiment, refer to Figure 3 and Figure 4 The frame 100 is equipped with a first activated carbon module 800, which is connected to the RO membrane module 500 and the second water outlet 720. The first activated carbon module 800 is also connected to the mixing valve 600 and the first water outlet 710. Water that flows sequentially through the inlet 200, the pre-filter assembly 300, the ultrafiltration membrane module 400, the RO membrane module 500, and the first activated carbon module 800 can be output through the second water outlet 720; water mixed by the mixing valve 600 can be output through the first activated carbon module 800 and then through the first water outlet 710.

[0040] Understandably, the first activated carbon module 800 is an activated carbon filter element, which can adsorb residual chlorine and organic pollutants in water and remove odors.

[0041] The above structure enables the design of a dual-path shared single first activated carbon module 800, thereby achieving the effect of saving space and cost.

[0042] In some embodiments, there are two first activated carbon modules 800, one of which is connected to the RO membrane module 500 and the second water outlet 720, and the other is connected to the mixing valve 600 and the first water outlet 710.

[0043] In this embodiment, refer to Figure 3 and Figure 4 The pre-filter assembly 300 includes a PP module 310 and a second activated carbon module 320. The inlet section 200, PP module 310, second activated carbon module 320, ultrafiltration membrane module 400, mixing valve 600, and first outlet section 710 are sequentially connected. The PP module 310 is a PP filter element, which acts as a coarse filtration device, removing large particulate impurities such as suspended solids, rust, and silt from the water through physical interception. The second activated carbon module 320 is an activated carbon filter element, which adsorbs residual chlorine and organic pollutants in the water, removing odors.

[0044] Understandably, water entering from the inlet 200 can flow sequentially through the PP module 310 and the second activated carbon module 320 before entering the ultrafiltration membrane module 400. The PP module 310 and the second activated carbon module 320 can perform preliminary filtration of the water.

[0045] In this embodiment, refer to Figure 1 and Figure 4 The frame 100 is equipped with a first detection element 910, which can detect the water pressure of the water output from the ultrafiltration membrane module 400; the frame 100 is equipped with a second detection element 920, which can detect the water pressure of the water before it enters the RO membrane module 500. Both the first detection element 910 and the second detection element 920 are configured as water pressure gauges.

[0046] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
