Technical Field

[0001] The utility model relates to the technical field of activated carbon rod filter element equipment, in particular to an activated carbon rod filter element component. Background Art

[0002] Household water filter cartridges are a key component of household water purifiers. Their main function is to remove impurities, odors, and harmful substances in water to improve the safety and taste of household water. Household water filter cartridges perform deep treatment of tap water through physical filtration, chemical adsorption, or membrane separation. According to different filtration principles and technologies, filter cartridges can be divided into many types. Water purifier filter cartridges are the core components of water purifiers. They are of many types and each has its own characteristics. Their main purpose is to remove impurities, odors, and harmful substances in water through physical filtration, chemical adsorption, or membrane separation, thereby improving water quality. In the existing technology, activated carbon fiber filter cartridges are mostly fixed and integrated, which are not convenient for disassembly and replacement, and are not convenient for cleaning when replacing the filter cartridges. Often, some filters have reached the end of their life, while the internal filter cartridges still have a long service life, resulting in waste of filter cartridges.

[0025] The following will be combined with the 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-6 The utility model provides a technical solution: an activated carbon rod filter element assembly, comprising an upper mounting ring 1, a lower mounting ring 2, an activated carbon rod barrel 3, a filter element 4 and a limiting member 5; the activated carbon rod barrel 3 is installed between the upper mounting ring 1 and the lower mounting ring 2, the filter element 4 is installed at the bottom of the activated carbon rod barrel 3, and the limiting member 5 is arranged at the bottom of the lower mounting ring 2 for fixing the filter element 4.

[0027] like Figure 1 As shown, the stopper 5 includes a plate body 51 fixedly mounted on both sides of the filter element 4. Both sides of the inner wall of the lower mounting ring 2 are provided with grooves 52 for inserting the plate body 51. The insides of the two grooves 52 are provided with circular grooves 53. The inside of the plate body 51 is provided with an elastic member 50 adapted to the circular grooves 53.

[0028] In this embodiment, the activated carbon rod cartridge 3 can effectively remove impurities such as residual chlorine, odor, and color in the water, thereby improving the taste and quality of the water. Due to its strong air permeability, large surface area, and small pore size, the activated carbon rod filter element can also adsorb organic matter and heavy metal ions in the water, reducing pollutants in the water. The use of the activated carbon rod filter element can purify a variety of water sources such as tap water, faucet water, and well water, making the water quality healthier and more natural. The filter element 4 is mainly a porous membrane made of inorganic materials with stable chemical properties. Under pressure, water flows inside the filter tube or outside the filter element. Flow, small molecules (such as water molecules) can pass through the filter element 4, while large molecules (such as impurities, bacteria, viruses, etc.) are intercepted by the filter element, thereby achieving the purpose of separation and purification. The filter element 4 can effectively remove suspended matter, impurities, bacteria, viruses and other harmful substances in the water, providing cleaner and safer drinking water. The filter element 4 has a long service life and is reusable, which reduces the cost of use. The filter element 4 can restore its filtering performance through simple cleaning during use, without the need for frequent replacement. The filter element 4 is made of environmentally friendly materials and will not cause pollution to the environment.

[0029] The filter element 4 needs to be cleaned frequently and can be reused. By simultaneously moving the two shift blocks 504 away from each other, the shift blocks 504 will drive the insertion rod 503 to move in the groove body 501 and squeeze the spring 502 until one end of the insertion rod 503 is disengaged from the circular groove 53, and the plate body 51 can be taken out from the groove 52, thereby realizing the removal of the filter element 4 from the PP cotton filter element for cleaning. After long-term use, when the service life of the external activated carbon rod tube 3 expires, the internal filter element 4 can be disassembled and continued to be used, which is also convenient for disassembling the filter element 4 for cleaning.

[0030] like Figure 6 As shown, the elastic member 50 includes a groove 501 provided inside the plate 51, a spring 502 is clamped inside the groove 501, an insertion rod 503 is clamped at one end of the spring 502, one end of the insertion rod 503 is adapted to the circular groove 53, and a shift block 504 is integrally processed on the surface of the insertion rod 503;

[0031] By shifting the shifting block 504 , the insertion rod 503 can be driven to move and compress the spring 502 , and the insertion rod 503 is engaged with the circular groove 53 , so that the plate body 51 is fixed on the lower mounting ring 2 .

[0032] like Figure 4 As shown, the surface of the plate body 51 is provided with a slide groove for the sliding block 504, and the surface of the filter element 4 is integrally processed with two sliding plates 6;

[0033] The slide groove portion is provided for movement and adjustment of the shift block 504 , and the shift plate 6 is provided for easy removal and installation of the filter element 4 .

[0034] like Figure 6As shown, the spring 502 is movably sleeved with a rod 7, one end of the rod 7 is fixedly mounted inside the slot 501, and one side of the insertion rod 503 is provided with an alignment groove 8 for inserting the rod 7;

[0035] Specifically, as the rod 503 moves, the alignment groove 8 inside the rod 503 slides on the surface of the rod body 7, enhancing the guiding function of the rod 503 and protecting the spring 502, preventing the spring 502 from bending and becoming unusable. The spring 502 is rust-proof and is primarily made of corrosion-resistant materials such as stainless steel. Stainless steel, because it contains elements such as chromium and nickel, can form a dense oxide film on its surface, effectively resisting oxidation and corrosion.

[0036] like Figure 3 As shown, a PP cotton filter cartridge 9 is installed on the inner wall of the activated carbon rod cartridge 3;

[0037] It should be noted that the PP cotton filter cartridge 9 is mainly made of polypropylene fiber. The PP material is resistant to acid and alkali corrosion, not easy to react with other chemical substances, has high mechanical strength and toughness, and can withstand certain pressure and impact; the PP fiber is fine and can effectively intercept suspended matter and impurities in the water and tiny particles in the air; some PP cotton filter cartridges 9 support cleaning and recycling, which is beneficial to environmental protection and resource conservation. As a pre-filter, the PP cotton filter cartridge 9 can preliminarily filter large particles of impurities, mud, rust, etc. in the water, and protect subsequent water purification equipment from blockage and damage. It is widely used in household water purifiers, commercial water purifiers and other equipment to improve water purification effects.

[0038] like Figure 5 As shown, a sealing ring 10 is fixedly mounted on the surface of the filter element 4, and the surface of the sealing ring 10 is tightly fitted with the inner wall of the PP cotton filter cartridge 9;

[0039] Furthermore, a sealing ring 10 is provided between the filter element 4 and the PP cotton tube, thereby achieving a better sealing effect.

[0040] like Figure 5 As shown, the two sides of the two plates 51 are slidably mounted with limit plates 11, and the tops of the four limit plates 11 are fixedly mounted on the bottom of the lower mounting ring 2;

[0041] In order to provide a limiting guide for the placement of the two plates 51 , a limiting plate 11 is provided to limit the plates 51 .

[0042] like Figure 1 As shown, the upper mounting ring 1 and the lower mounting ring 2 are both configured as polypropylene rings;

[0043] It is worth noting that polypropylene has extremely strong corrosion resistance to acids, alkalis, salts and other chemical substances, and can work stably under high temperature, high pressure and harsh environments. Polypropylene has high strength and rigidity, and is light in weight, which makes it an ideal material for making various structural parts and lightweight products. Polypropylene is a non-toxic, odorless, tasteless milky white highly crystalline polymer that does not release harmful substances and meets environmental protection requirements.

[0044] like Figure 4 As shown, the outer surface of the activated carbon rod tube 3 is installed with a non-woven fabric layer 12;

[0045] Furthermore, the non-woven fabric on the filter element's surface is primarily made of fiber materials, the most common of which are polyester and terylene. These fibers possess excellent physical and chemical properties, such as high-temperature resistance, resistance to melting, water absorption, and corrosion resistance, making them ideal for use in the filter element's filter layer. The porous structure of the non-woven fabric effectively intercepts and filters tiny particles, impurities, and bacteria in the air or water. Its filtration accuracy can be adjusted as needed to meet the filtration requirements of different applications.

[0046] The filter element 4 of this device needs to be cleaned frequently and can be reused. By simultaneously shifting the two shift blocks 504 away from each other, the shift blocks 504 will drive the insertion rod 503 to move in the groove body 501 and squeeze the spring 502 until one end of the insertion rod 503 is disengaged from the circular groove 53, and the plate body 51 can be taken out from the groove 52, thereby realizing the removal of the filter element 4 from the PP cotton filter element for cleaning. After long-term use, when the service life of the external activated carbon rod tube 3 expires, the internal filter element 4 can be disassembled and continued to be used, which is also convenient for disassembling the filter element 4 for cleaning.

[0047] 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.
