Description

Technical Field

[0001] This utility model relates to the field of water purification equipment technology, and in particular to a water purification filter element with a track etching membrane. Background Technology

[0002] Water purifier filter cartridges are the core filtration components of water purification equipment. Their function is to purify the water entering the equipment. They are usually made of a variety of filter materials, each targeting different contaminants. For example, PP cotton filter cartridges can intercept large particles of impurities in the water, such as sediment and rust; activated carbon filter cartridges can adsorb residual chlorine, discoloration, and odors in the water; while ultrafiltration or reverse osmosis membrane filter cartridges can further filter out tiny particles, bacteria, viruses, and even heavy metal ions. Through the synergistic effect of multiple filter cartridges, harmful substances in the water can be effectively removed, water quality can be improved, and healthier and safer drinking water can be provided for people. They are widely used in homes, businesses, and industries.

[0003] With increasing public concern about water safety and health, water purification equipment has become crucial for ensuring water quality. As the core component of water purification equipment, the performance of water filter cartridges directly affects the purification effect. However, the existing water filter cartridges have a relatively simple structure, resulting in limitations in the filtration effect and performance of the equipment. The filter cartridges have limited filtration precision, making it difficult to effectively intercept tiny impurities, bacteria, viruses, and other harmful substances in the water, thus failing to provide users with sufficiently safe drinking water. At the same time, the installation and replacement of existing filter cartridges are complicated and require professional personnel with specific tools, which not only increases the cost of use but also reduces the user experience.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] Example 1: Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a water filter element with a track etching membrane, including a shell 1, a bottom cylinder 2 connected to the bottom of the shell 1, a sealing cover 3 installed on the top of the shell 1, a water inlet pipe 4 connected to the top of the sealing cover 3, and a flange provided at the top of the water inlet pipe 4. An installation cylinder 5 is provided inside the shell 1, and multiple sets of slots 6 are opened on the outer side of the installation cylinder 5. Multiple sets of track etching membrane filter element bodies 7 are inserted into the inner wall of the slots 6.

[0024] The outer shell 1 serves as the main frame of the entire water purification filter element, providing installation space and protection for the internal components. This ensures stable and coordinated operation of all parts during the water purification process and prevents damage to the internal structure from external factors. The bottom cylinder 2 collects the water filtered by the filter element and guides it to subsequent drainage or output stages. The sealing cap 3 prevents external impurities from entering the filter element, ensuring the purity of the purified water. It also provides the mounting base for the inlet pipe 4, the channel through which water enters the filter element. The flange design facilitates connection and fixation of the inlet pipe 4 to other water source pipes, ensuring smooth water intake. The mounting cylinder 5 is the mounting carrier for the track etching membrane filter element body 7. The slot 6 is used to insert the track etching membrane filter element body 7, positioning and fixing it to ensure accurate installation on the mounting cylinder 5 and guaranteeing the water purification effect. The track etching membrane filter element body 7 is the core filtration component of the water purification filter element. Equipped with a track-etched membrane, this filter cartridge filters water entering the cartridge, removing impurities, particles, bacteria, and other harmful substances to achieve water purification. It's important to note that the track-etched membrane filter cartridge body 7 is the main body of the filter cartridge, using the track-etched membrane as the core filtration medium. It forms uniform cylindrical micropores on a polymer film through high-energy particle irradiation and chemical etching processes. This results in precisely controllable pore size, strong chemical stability, high mechanical strength, and a smooth, flat surface. The pore size distribution is extremely narrow, the pore shape is regular, and it is perpendicular to the membrane surface, achieving precise retention. By adjusting the irradiation dose and etching time, different pore sizes (such as 0.1μm, 0.2μm, 0.4μm, etc.) can be customized to meet precision filtration needs. The membrane thickness is typically 6-11μm, with a smooth, flat surface and a semi-transparent state, facilitating microscopic observation. Commonly used materials include polycarbonate, polyester, and polyimide, with polycarbonate being the most widely used due to its high etching sensitivity and ability to produce small pore sizes (as small as 0.01μm).

[0025] The inner wall of the bottom cylinder 2 is connected to a horizontally arranged water guide pipe 8, and a partition is fixed to the inner wall of the water guide pipe 8. The inner wall of the water guide pipe 8 is connected to two vertically arranged water supply pipes 9, and a connecting component 10 is provided at both ends of the water guide pipe 8.

[0026] The water guide pipe 8 is used to guide and distribute water flow. The internal space of the water guide pipe 8 can be divided by the baffle fixed on its inner wall. The water delivery pipe 9 is used to deliver the filtered water to different output channels of the water guide pipe 8 to meet different usage needs. The connecting component 10 can connect the drain pipe 11 to the water guide pipe 8 through its internal structure, while ensuring the sealing of the connection.

[0027] The connecting component 10 includes two sets of threaded grooves 101 opened at both ends of the water guide pipe 8. Both ends of the water guide pipe 8 are fitted with mounting caps 102, and the inner wall of the mounting cap 102 is threadedly connected to the outer side of the threaded groove 101. A sealing gasket 103 is provided on the inner wall of the mounting cap 102.

[0028] The threaded groove 101 provides a foundation for the threaded connection of the mounting cover 102. The threaded connection enables the mounting cover 102 to be tightly fixed to the water guide pipe 8. The mounting cover 102 serves two purposes: firstly, it seals both ends of the water guide pipe 8 to prevent water leakage; secondly, it cooperates with the positioning ring 12 of the drain pipe 11 to fix the position of the drain pipe 11. The sealing gasket 103 further enhances the sealing between the mounting cover 102 and the water guide pipe 8, preventing water leakage during the water purification process and ensuring the normal operation of the filter element.

[0029] Example 2: This is the second embodiment of the present invention, which is based on the previous embodiment.

[0030] Specifically, a drain pipe 11 is inserted into the inner wall of the water pipe 8, and a positioning ring 12 is fixed on the outer side of the drain pipe 11, with one side of the positioning ring 12 fitting against the inner wall of the mounting cover 102.

[0031] The drain pipe 11 is designed to discharge the filtered water from the filter element. The positioning ring 12 fixed on its outer side can position the drain pipe 11, ensuring that the drain pipe 11 is accurately installed in the water guide pipe 8 and that the drainage is smooth.

[0032] Specifically, the bottom of the bottom cylinder 2 is fixed with a mounting plate 13, and the inner wall of the mounting plate 13 is provided with four sets of mounting holes 14.

[0033] The mounting plate 13 is designed to provide a mounting base for the entire filter element. Through the four sets of mounting holes 14 on its inner wall, the filter element can be fixed inside the water purification equipment with bolts to ensure the stability of the filter element.

[0034] Specifically, a connecting flange 15 is installed on the top of the outer casing 1, and the top of the connecting flange 15 is fixedly connected to the bottom of the sealing cover 3. The inner wall of the connecting flange 15 is threaded with multiple sets of fixing bolts 16.

[0035] The connection strength and sealing performance between the sealing cover 3 and the outer shell 1 can be enhanced by connecting flange 15 to prevent water leakage. The fixing bolts 16 are used to further tighten the sealing cover 3 and the outer shell 1 to ensure that the connection between the two is firm and will not loosen or separate due to water pressure or other factors during the water purification process.

[0036] Example 3: This is the third embodiment of the present invention, which is based on the first two embodiments.

[0037] Specifically, the top and bottom ends of the mounting cylinder 5 are respectively fitted with a top cover 18 and a bottom cover 17, and the inner walls of the bottom cover 17 and the top cover 18 are provided with multiple sets of through holes 19.

[0038] The bottom cover 17 and the top cover 18 work together to protect the internal structure of the mounting cylinder 5 and fix the internal components. The multiple through holes 19 on its inner wall allow water to flow through, and may also disperse and guide the water flow, so that the water flows more evenly through the track etched membrane filter body 7 and improves the filtration effect.

[0039] Specifically, the inner walls of the bottom cover 17 and the top cover 18 are respectively fixed with a first sealing plug 20 and a second sealing plug 21, and the outer sides of the first sealing plug 20 and the second sealing plug 21 are mutually fitted with the inner wall of the mounting cylinder 5.

[0040] By using the first sealing plug 20 and the second sealing plug 21 together, water leakage can be prevented from the gap between the mounting cylinder 5 and the bottom cover 17 and the top cover 18, thus ensuring the sealing and effectiveness of the water purification process.

[0041] Specifically, multiple sets of fixing rings 22 are fixed to the inner wall of the outer shell 1, and the inner wall of the fixing rings 22 is engaged with the outer side of the track etching membrane filter body 7.

[0042] The fixing ring 22 can further fix and support the track etching membrane filter body 7, prevent the track etching membrane filter body 7 from moving or shaking due to water flow impact during the water purification process, and ensure the filtration effect and service life of the track etching membrane filter body 7.

[0043] Working Principle: When this water filter cartridge equipped with a track etching membrane is in operation, the external water source pipe is first connected to the inlet pipe 4 via the flange at the top of the inlet pipe 4. Water flows in from the inlet pipe 4 and enters the housing 1 through the sealing cover 3. At this time, the housing 1 provides a closed space for the entire filtration process. The water flowing into the housing 1 flows downward to the mounting cylinder 5. The water is purified by multiple sets of track etching membrane filter cartridge bodies 7 inserted into the outside of the mounting cylinder 5. At the same time, because the track etching membrane filter cartridge body 7 has a track etching membrane, water will pass through the through hole 19 into the inside of the mounting cylinder 5. The track etching membrane performs fine filtration of the water, removing impurities, bacteria and other harmful substances in the water. The fixing ring 22 on the inner wall of the housing 1 is engaged with the outside of the track etching membrane filter cartridge body 7, ensuring the track etching membrane filter cartridge body 7... To ensure stability and prevent displacement under water flow impact, thus affecting filtration efficiency, the filtered water flows to the bottom cylinder 2 by gravity. At this time, the water supply pipe 9 guides the water flow into the water guide pipe 8. The water flow is rationally distributed by the baffle inside the water guide pipe 8. The mounting cover 102 is threadedly connected to the threaded groove 101, and the sealing gasket 103 ensures a tight seal to prevent leakage. The drain pipe 11 inserted inside the water guide pipe 8 has a positioning ring 12 on its outer side that fits against the inner wall of the mounting cover 102, which serves to position the drain pipe 11. The filtered water is discharged through the drain pipe 11. In addition, the mounting plate 13 and mounting hole 14 at the bottom of the bottom cylinder 2 make it easy to install the entire filter element in the water purification equipment. The connecting flange 15 and fixing bolts 16 ensure the firm connection between the sealing cover 3 and the outer shell 1.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
