[0034] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 In one embodiment, a nitrate treatment device for drinking water includes a mounting frame 1 and an upper shell 2. The upper shell 2 is provided on one side of the mounting frame 1, and a plurality of tanks 3 are provided on the other side of the mounting frame 1. The plurality of tanks 3 are sequentially filled with PP cotton, ion exchange resin and activated carbon 4. The plurality of tanks 3 are connected by connecting pipes 5. The mounting frame 1 is provided with an inlet pipe 6 and an outlet pipe 7. One end of the inlet pipe 6 passes through the mounting frame 1 and extends into the tank 3 filled with PP cotton. One end of the outlet pipe 7 passes through the tank 3 filled with activated carbon 4 and is connected to the outlet pipe 7. The other ends of the inlet pipe 6 and the outlet pipe 7 extend outward through the upper shell 2.

[0035] As can be understood, the incoming water enters through the PP cotton tank 3, and the forced water flow passes through three stages of filtration in sequence, effectively treating nitrates in drinking water. Specifically, the water source enters the PP cotton for primary filtration, removing large particles such as sediment and rust, protecting subsequent filter media, and extending the lifespan of the ion exchange resin and activated carbon 4. It then enters the tank 3 filled with ion exchange resin, where the ion exchange resin selectively adsorbs nitrates (NO3⁻). Finally, the nitrate-treated water source enters the tank 3 filled with activated carbon 4, where the activated carbon 4 adsorbs residual organic matter, odors, and disinfection byproducts (such as residual chlorine). The drinking water undergoes further filtration or purification through the above flow process.

[0036] Furthermore, the barrel 3 is made of transparent acrylic material, which users can replace according to the color change of the PP cotton or the usage time of the barrel 3, thereby achieving continuous purification of drinking water.

[0037] In summary, this application achieves efficient, stable, and easy-to-maintain nitrate removal through modular structural design and multi-stage filter media combination. By packaging PP cotton, ion exchange resin, and activated carbon 4 into independent tanks 3, the filter media can be replaced individually without the need for overall disposal, which helps reduce long-term operating costs. At the same time, installation and replacement only require disassembly and assembly of tank 3, without the need for complex component disassembly and assembly. The overall structure is simple and more convenient to maintain, making it suitable for home installation. Furthermore, this application does not require electric drive and relies on natural water pressure filtration, making it suitable for areas without electricity.

[0038] Specifically, please refer to Figure 1 , Figure 2 Based on the above embodiments, it also includes a control box 8, an electrically controlled valve 9, and a control panel 10. The control box 8 is installed on the mounting bracket 1, the electrically controlled valve 9 is installed on the water inlet pipe 6, and the control panel 10 is installed on the upper housing 2. The control panel 10, the electrically controlled valve 9, and the control box 8 are electrically connected.

[0039] It is understandable that ion exchange resin needs an appropriate contact time to efficiently adsorb nitrates. By selecting the corresponding button on the control panel 10, a corresponding signal can be sent to the control box 8, thereby enabling the flow rate to be adjusted using the electronically controlled valve 9 to meet the requirements. By controlling the inlet water flow rate, it is ensured that the water flows through the PP cotton, ion exchange resin and activated carbon 4 at the optimal flow rate, avoiding insufficient filtration due to excessive flow rate.

[0040] Specifically, please refer to Figure 2 , Figure 4 , Figure 5 Based on the above embodiments, the mounting bracket 1 has several mounting holes 11 on the side near the barrel 3, and several barrels 3 are threadedly connected through the mounting holes 11.

[0041] It is understandable that the mounting hole 11 and the barrel body 3 are connected by threads. When disassembling and assembling, the user only needs to rotate the barrel body 3. The whole process is easy to disassemble and assemble, has a good sealing effect, and is easy to maintain.

[0042] Specifically, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 Based on the above embodiments, it also includes an annular gasket 12 and a cover plate 13. An annular gasket 12 is provided in a plurality of mounting holes 11, and a cover plate 13 is provided on the inner ring of the annular gasket 12. A through hole is provided on the cover plate 13.

[0043] It is understandable that by setting the cover plate 13 and the annular gasket 12, a sealing effect can be achieved, further realizing the sealing effect and avoiding water leakage.

[0044] Specifically, please refer to Figure 2 Based on the above embodiments, a lower housing 14 is also included. The mounting frame 1 is provided with the lower housing 14 on one side of the barrel 3. The lower housing 14 is connected to the clamping assembly 15 provided on the mounting frame 1.

[0045] It is understandable that by setting the lower shell 14, the tank 3 can be wrapped to prevent the tank 3 from being disturbed by external forces or accidentally touched by children, which could cause it to fall or become loose and affect the water purification effect.

[0046] Specifically, please refer to Figure 2 , Figure 3 , Figure 4 Based on the above embodiments, the clamping assembly 15 includes a hook 1501, a wedge block 1502, a guide groove 1503, a spring 1504, and a pull rope 1505;

[0047] The lower housing 14 is provided with a hook 1501, and the mounting bracket 1 has grooves on both sides, a guide groove 1503 is provided in the groove, and a wedge block 1502 is slidably provided in the guide groove 1503.

[0048] A spring 1504 is provided between the wedge block 1502 and the guide groove 1503. One end of the pull rope 1505 is connected to the wedge block 1502, and the other end of the pull rope 1505 extends outward through the mounting bracket 1.

[0049] It is understandable that by setting the clamping component 15, the effect of quick installation and quick disassembly can be achieved. When disassembling, the pull rope 1505 is pulled manually, the spring 1504 is compressed, the wedge block 1502 is no longer connected to the oblique opening on the hook 1501, and the lower housing 14 is separated from the mounting frame 1 due to its own weight or by manual pulling.

[0050] During installation, the hook 1501 on the lower housing 14 presses against the inclined surface of the wedge block 1502, causing the spring 1504 to compress. When the hook 1501 moves to the maximum stroke of the maximum groove, the wedge block 1502, under the reset action of the spring 1504, just fits into the inclined opening of the hook 1501, thereby locking the hook 1501 and thus installing the lower housing 14.

[0051] Specifically, please refer to Figure 2 , Figure 4 Based on the above embodiments, it also includes a partition 16 and a filter plate 17. A partition 16 is provided in several barrels 3, and a filter plate 17 is symmetrically provided at both ends of the partition 16. The side of the filter plate 17 away from the partition 16 is connected to the inner wall of the barrel 3.

[0052] It is understandable that by setting up the baffle 16 and the filter plate 17, the flow of water can be guided to a certain extent, ensuring that the water flows one by one. When the drinking water flows, it first passes through the filter plate 17 on one side of the baffle 16, and then flows out from the filter plate 17 on the other side. Through the above settings, the contact area between the flowing water and the PP cotton, ion exchange resin and activated carbon 4 can be wider, giving full play to the role of the PP cotton, ion exchange resin and activated carbon 4.

[0053] Specifically, please refer to Figure 2 , Figure 4 Based on the above embodiments, it also includes a sponge board 18. A plurality of sponge boards 18 are provided in the lower housing 14, and the side of the plurality of sponge boards 18 away from the lower housing 14 is connected to the bottom of the barrel 3.

[0054] It is understandable that by setting the sponge board 18, support and cushioning can be provided to prevent the barrel 3 from being suspended in the air. The sponge board 18 can also eliminate the gap between the barrel 3 and the lower shell 14.

[0055] Specifically, please refer to Figure 2 , Figure 4 Based on the above embodiments, a one-way valve 19 is also included, and a one-way valve 19 is provided on the connecting pipe 5.

[0056] It is understandable that adding a one-way valve 19 to the connecting pipe 5 can solve the problem of reverse mixing of water flow in a multi-stage filtration system and maintain the forward water flow path.

[0057] Specifically, please refer to Figure 4 , Figure 6 Based on the above embodiments, it also includes screw holes 20, and the mounting bracket 1 is provided with a plurality of screw holes 20.

[0058] It is understandable that before the screw holes 20 are provided, the device is placed on the ground, that is, the bottom of the lower housing 14 is in contact with the ground or tabletop; by providing the screw holes 20, the corresponding brackets or hooks 1501 can be installed, so that the whole unit can be connected to the wall, realizing another way of placing the device.

[0059] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, apparatus, article, or method that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, apparatus, article, or method.
