[0002] Existing natural water purification systems typically use filtration units within a filter tank to purify water. These units are typically composed of stacked filter media. Using different filter media materials, the filtration process is completed to remove impurities and harmful substances from the water. However, existing filtration methods have some shortcomings.

[0003] First, the filter units within existing filter tanks all consist of stacked filter media, lacking the ability to combine and customize them. This means each filter unit can only use one type of filter media, preventing flexible combination and adjustment based on demand. This limits the improvement of filtration effectiveness and the expansion of its application range.

[0004] Secondly, existing filtration methods are relatively simple. Because the type and arrangement of filter media are fixed, they cannot be adjusted or optimized according to changes in water quality. This can lead to suboptimal filtration results in certain situations, failing to meet user water quality requirements.

[0005] Therefore, in view of the deficiencies in the prior art, it is necessary to design a novel natural water purification device to solve the above problems and improve the effect and efficiency of water purification. Utility Model Content

[0036] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. As long as the effects of the present invention can be exerted, various changes can be made to the embodiments.

[0037] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0038] Reference Figure 1-7 A drinking natural water purification device based on medical stone powder filter material according to this embodiment is described.

[0039] like Figure 1 As shown, the device includes a filter tank body 1, which comprises a main body and upper and lower heads fixed to the upper and lower ends of the main body. The upper head is provided with an inlet, an exhaust port, and a threaded port. Two manholes, several observation mirrors, and several side ears for hanging are provided on the outer wall of the main body. The lower head is provided with an outlet and support legs. A filtering mechanism is provided within the inner cavity of the filter tank body 1.

[0040] In this embodiment, the filtering mechanism includes a first filtering unit 2, a second filtering unit 4, a third filtering unit 5 and a fourth filtering unit 6 which are sequentially arranged from top to bottom.

[0041] Specifically, the first filter unit 2 includes a first filter material layer 21 , and the first filter material layer 21 is quartz sand.

[0042] like Figure 1 and Figure 7 As shown, the first filter unit 2 further includes a support cover 22 that supports the first filter material layer 21. A converging chamber 3 is formed between the bottom of the support cover 22 and the second filter unit 4. After coarse filtration with the quartz sand, the water is collected in the converging chamber 3 and evenly distributed on the filter assembly 42 for secondary filtration.

[0043] The support cover 22 in this embodiment comprises a first positioning frame 221 and a second positioning frame 222 arranged vertically. A mesh frame 223 is secured between the first and second positioning frames 221 and 222. The mesh frame 223 serves as the cover body, which snaps downward. Several reinforcing ribs are provided on the mesh frame 223, with their ends secured to the first and second positioning frames 221 and 222. The mesh frame 223 acts as a barrier, supporting the quartz sand and preventing it from falling.

[0044] like Figure 2 and Figure 3 As shown, the second filter unit 4 includes a plurality of filter assemblies 42 arranged in sequence. It also includes a base 41, on which the filter assemblies 42 are closely arranged. A filler is provided on the inner sidewall of the base 41 to fill the gap between the edges of the closely arranged filter assemblies 42 and the base 41, thereby ensuring that the filter assemblies 42 are stably mounted on the base 41.

[0045] The filter assembly 42 includes a plurality of closely arranged medical stone cylindrical members 421. A cavity 422 is formed within each of the medical stone cylindrical members 421. The cavity 422 has a closed bottom and an open top. A first filter block 423, made of a columnar activated carbon material, is disposed within the cavity 422. The outer wall of the first filter block 423 mates with the inner wall of the cavity 422.

[0046] like Figure 2 Shown, in order to make a plurality of medical stone cylindrical parts 421 closely arranged together, the outer wall surface of the medical stone cylindrical part 421 is designed to polygonal shape. Adopt hexagon in this embodiment. Strengthen the compactness and stability after the medical stone cylindrical part 421 is arranged by being set to hexagon.

[0047] like Figure 1 As shown, the third filter unit 5 includes a second filter material 51, which is filled between the second filter unit 4 and the fourth filter unit 6. The second filter material 51 is preferably medical stone particles.

[0048] like Figure 4 、 Figure 5 and Figure 6 As shown, the fourth filter unit 6 includes a first flange 62 and a second flange 65, and also includes an outer limit frame 63 and an inner limit frame 64 arranged opposite to each other. The outer limit frame 63 and the inner limit frame 64 are fixed between the first flange 62 and the second flange 65 to form a sandwich cavity 67. A second filter material layer 68 is sandwiched between the outer limit frame 63 and the inner limit frame 64, and the second filter material layer 68 is filled in the sandwich cavity 67.

[0049] The clamping cavity 67 is an annular cavity or an inclined sheet-shaped cavity.

[0050] like Figure 5 As shown, the first flange 62 and the second flange 65 are arranged up and down, and the diameter of the first flange 62 is smaller than that of the second flange 65. At this time, when the outer limit frame 63 and the inner limit frame 64 are connected to the first flange 62 and the second flange 65, the clamping cavity 67 has an annular cavity structure and is trapezoidal in shape when projected in the main view, so that water can contact the second filter material layer 68 when falling from top to bottom.

[0051] like Figure 6 As shown, the outer limit frame 63 and the inner limit frame 64 are fixed on the filter tank body 1, and the first flange 62 and the second flange 65 are arranged on the left and right, and are arranged in the clamping cavity 67 formed between the outer limit frame 63 and the inner limit frame 64. At this time, the clamping cavity 67 is a sheet-like cavity structure, which is inclined under the main view projection, so that water can contact the second filter material layer 68 when falling from top to bottom.

[0052] like Figure 4 and Figure 5 and Figure 6 As shown, the first flange 62 and the second flange 65 are connected to a feed pipe 61 and a discharge pipe 66, respectively. The feed pipe 61 and the discharge pipe 66 are both connected to the filter tank body 1, and the horizontal position of the feed pipe 61 is higher than that of the discharge pipe 66. Valves are provided on the feed pipe 61 and the discharge pipe 66.

[0053] In one embodiment, the second filter layer 68 is a ceramsite filter layer, a KDF55 filter layer, or other desired filter media. In actual use, the second filter layer 68 can be replaced via the feed pipe 61 and the discharge pipe 66. For example, the discharge pipe 66 is closed, and the required filter material is introduced into the clamping chamber 67 through the feed pipe 61. Once the chamber is full, the feed pipe 61 is closed. To change the material, the discharge pipe 66 is opened to allow the added filter material to flow out, and then the filter material is refilled. The user can select the material of the final filter layer based on actual filtration needs.

[0054] Working Principle: Natural water is coarsely filtered through quartz sand as it passes through the first filter layer 21. The coarsely filtered water then permeates downward into the converging chamber 3. After converging, the water is evenly distributed on the filter assembly 42 and filtered a second time by the filter assembly 42. The filter assembly 42 comprises a medical stone cylindrical member 421 and columnar activated carbon disposed therein. After passing through the activated carbon, the natural water then passes through the medical stone cylindrical member 421. As it permeates downward, it passes through the medical stone particles in the third filter unit 5 and continues to permeate downward through the second filter layer 68 for final filtration.

[0055] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
