Description

Technical Field

[0001] This utility model relates to the field of water purifier filter technology, and in particular to a multi-layer protective water purifier filter. Background Technology

[0002] As people's living standards continue to improve, their demands for drinking water quality are also increasing. They are paying more and more attention to the safety and health of drinking water, hoping to obtain purer and healthier drinking water through effective filtration equipment. Carbon rod filter cartridges, due to their excellent adsorption properties, can effectively remove odors, residual chlorine, organic matter, and other impurities from water, meeting consumers' needs for improved water quality. However, long-term use of existing water purifier filter cartridges can easily cause rust to form on the springs. This undoubtedly increases the load on the filter cartridge when filtering water, and it is also not easy to disassemble and maintain, thus limiting its use.

[0003] Existing technology, patent number CN218188196U, discloses a water purifier filter element with a protective structure. This structure, through the setting of protective filtration components, has a simple and reasonable overall design. Through the corresponding cooperation of various components, water, upon contact with the diversion ring, enters through the diversion groove and then contacts the buffer filter pad. The water is then diverted and buffered through the inner wall of the diversion groove, preventing backflow of water due to excessive water flow in the water purifier. Simultaneously, it not only filters the water entering the outer tank but also supports the inner tank, increasing its load-bearing capacity and giving the filter element a certain rigidity. It also facilitates one-time cleaning and replacement, effectively preventing the filter element from falling and being damaged. However, in actual use, this existing technology relies on a first and second filter element for filtration, resulting in a single filtration method. This makes it difficult to significantly improve water quality in multiple dimensions, failing to meet people's demand for high-quality drinking water. Furthermore, all filtration is concentrated on these two layers, making the filter element prone to rapid clogging and shortening its lifespan. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a multi-layer protective water purifier filter element.

[0005] This utility model is achieved through the following technical solution:

[0006] A multi-layer protective water purifier filter element includes a filter element housing with pipe joints extending through both ends. The filter element housing contains a multi-layer protective mechanism. This mechanism includes a first support plate, a second support plate, a third support plate, and a fourth support plate fixedly disposed inside the filter element housing. Support columns are fixedly disposed between the first, second, third, and fourth support plates. Support meshes are fixedly disposed at the bottom of each of the first, second, third, and fourth support plates. A PP cotton layer is fixedly disposed inside the first support plate. Fixed meshes are inserted into the interiors of the second and third support plates. One of the fixed meshes contains granular activated carbon, and the other contains compressed activated carbon. An ultrafiltration membrane layer is disposed inside the fourth support plate. Two protruding blocks are fixedly disposed at the top of the fixed mesh. Two buffer pads are fixedly disposed on the inner wall of the filter element housing.

[0007] By adopting the above technical solutions, comprehensive filtration of various impurities such as silt, rust, odor, and bacteria can be achieved, ensuring clean and safe water quality. The support plate, support column, and support net provide stable physical support for each filter layer, ensuring stable operation of the filter element.

[0008] As a further description of the above technical solution: a support strip is fixedly provided on the inner wall of the filter element housing, a fixing rod is fixedly provided on the top of the support strip, a guide vane is fixedly provided on the surface of the fixing rod, a cleaning mechanism is provided on one side of the filter element housing, the cleaning mechanism includes a sealing groove formed on the surface of the filter element housing, a sealing strip is inserted into the inside of the sealing groove, and a fixing door is fixedly provided on one side of the sealing strip.

[0009] By adopting the above technical solutions, the water flow direction can be guided, the water can be more evenly distributed in the filter element, and each filter layer can be fully contacted with the water to improve filtration efficiency. The sealing groove and sealing strip work together to ensure airtightness. The fixed door is easy to open, which facilitates cleaning, maintenance or replacement of parts inside the filter element, extends the service life of the filter element and ensures the water purification effect.

[0010] As a further description of the above technical solution: the surface of the fixed door is provided with an installation groove, and tempered glass is fixedly installed inside the installation groove. Two handles are fixedly installed on one side of the fixed door. Multiple limiting frames are fixedly installed on the surface of the filter element housing. Limiting blocks are inserted into the interior of each of the multiple limiting frames. Threaded holes are provided on the surface of the limiting frames and the limiting blocks. Bolts are threaded into the interior of the threaded holes.

[0011] By adopting the above technical solution, the tempered glass in the fixed door mounting slot allows users to intuitively observe the condition of the filter layer inside the filter element, keep track of the filter element's usage, and make reasonable arrangements for maintenance and replacement. At the same time, it ensures the overall sealing of the filter element and guarantees the filtration effect.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This invention employs a multi-layered protective mechanism, utilizing a four-layer progressive filtration system consisting of a PP cotton layer, granular activated carbon, compressed activated carbon, and an ultrafiltration membrane layer. This system comprehensively removes various impurities from the water. The PP cotton layer intercepts large particles, ensuring the stable operation of subsequent filtration layers. The granular activated carbon adsorbs odors, residual chlorine, and some organic matter, improving taste and odor. The compressed activated carbon further refines the purification process, adsorbing tiny organic matter. The ultrafiltration membrane layer traps bacteria, viruses, and other tiny particles, enhancing the hygiene and safety of the water. The four layers work synergistically to produce clean, safe, and palatable water. Furthermore, the design of the support plates, support nets, and fixing nets ensures the stability of each filtration layer, guaranteeing stable and efficient operation of the filter element. This multi-layered protection meets users' demands for high-quality drinking water. Attached Figure Description

[0022] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] The embodiments disclosed in this application are as follows: Figure 1-5The illustrated multi-layer protective water purifier filter element includes a filter element housing 1, with pipe joints 2 extending through both ends of the filter element housing 1. The filter element housing 1 contains a multi-layer protective mechanism. This mechanism includes a first support plate 3, a second support plate 4, a third support plate 5, and a fourth support plate 6 fixedly disposed inside the filter element housing 1. Support columns 7 are fixedly disposed between each of the first, second, third, and fourth support plates 3 and 4. Support nets 8 are fixedly disposed at the bottom of each of the first, second, third, and fourth support plates 3 and 6. A PP cotton layer 9 is fixedly disposed inside the first support plate 3. Fixing nets 10 are inserted into the interiors of the second and third support plates 4 and 5. One of the fixed meshes 10 contains granular activated carbon 11, and the other fixed mesh 10 contains compressed activated carbon 12. The fourth support plate 6 contains an ultrafiltration membrane layer 13. Two protruding blocks 14 are fixedly installed on the top of the fixed meshes 10. Two buffer pads 15 are fixedly installed on the inner wall of the filter cartridge housing 1. When water enters the filter cartridge housing 1, the buffer pads 15 can buffer and reduce the noise generated by the water flow when the water flow impacts the buffer pads 15. Moreover, the guide vanes 18 can guide the direction of the water flow, so that the water is more evenly distributed inside the filter cartridge and fully contacts each filter layer to improve the filtration efficiency. The support strips 16 and the fixed rods 17 provide installation support for the guide vanes 18 to ensure the stability of its structure.

[0024] Next, the water reaches the first support plate 3, inside which a PP cotton layer 9 is fixedly installed, and a support net 8 is set at the bottom. The support net 8 provides physical support for the PP cotton layer 9 to prevent it from shifting or deforming under the impact of water flow. The PP cotton 9 has a large filter pore size and is mainly used to intercept larger particles in the water, such as silt, rust, and suspended solids. These large particles are blocked by the PP cotton layer 9 and adsorbed on its fiber surface, thereby achieving preliminary purification of the water.

[0025] After being filtered through the PP cotton layer 9, the water enters the second support plate 4. A fixed mesh 10 is installed inside the second support plate 4 via a plug-in connection. The fixed mesh 10 is filled with granular activated carbon 11. The granular activated carbon 11 has a rich porous structure and a large specific surface area. It can remove odors, residual chlorine, and some organic matter from the water through physical adsorption. These harmful substances in the water are adsorbed in the pores of the granular activated carbon, further improving the taste and smell of the water.

[0026] Next, water flows into the third support plate 5, which is also equipped with a fixing mesh 10. However, this fixing mesh 10 is filled with compressed activated carbon 12. Compressed activated carbon 12 is made by compressing activated carbon powder through a special process. Compared with granular activated carbon, it has a more compact structure and higher filtration precision. It can further adsorb residual micro-organic matter, discoloration, odor, etc. in the water, and perform more refined purification of the water quality.

[0027] Water filtered through the first three layers enters the fourth support plate 6, which contains an ultrafiltration membrane layer 13. The ultrafiltration membrane layer 13 has very fine pores, which can trap tiny particles such as bacteria, viruses, colloids, and large organic molecules in the water. The ultrafiltration membrane has high filtration precision, which can effectively improve the hygiene and safety of the water and make the filtered water purer. After being filtered through four layers of PP cotton, granular activated carbon, compressed activated carbon and ultrafiltration membrane, the water becomes clean, safe and tastes good. Finally, it flows out from the pipe connector 2 at the other end of the filter cartridge housing 1 and is available for user use.

[0028] Reference Figure 2-3 As shown, a support strip 16 is fixedly installed on the inner wall of the filter element housing 1, a fixing rod 17 is fixedly installed on the top of the support strip 16, and a guide vane 18 is fixedly installed on the surface of the fixing rod 17. A cleaning mechanism is provided on one side of the filter element housing 1. The cleaning mechanism includes a sealing groove opened on the surface of the filter element housing 1. A sealing strip 19 is inserted into the inside of the sealing groove. A fixing door 20 is fixedly installed on one side of the sealing strip 19. The pipe joint 2 at one end of the filter element housing 1 is connected to an external water inlet pipe, and the pipe joint 2 at the other end of the filter element housing 1 is connected to an external circulating water pump. The external circulating water pump is started so that the water to be filtered flows into the filter element from the pipe joint 2 at one end of the filter element housing 1, ensuring that the water can smoothly enter the filter element housing 1 for treatment.

[0029] After water enters the filter cartridge housing 1, when the water flow impacts the buffer pad 15, the buffer pad 15 can play a role in buffering and shock absorption, reducing the noise generated by the water flow. Moreover, the guide vane 18 can guide the direction of the water flow, so that the water is more evenly distributed inside the filter cartridge, fully contacting each filter layer and improving the filtration efficiency. The support bar 16 and the fixing rod 17 provide installation support for the guide vane 18 to ensure its structural stability.

[0030] Reference Figure 4-5As shown, the surface of the fixed door 20 has a mounting groove, and a tempered glass 21 is fixedly installed inside the mounting groove. Two handles 22 are fixedly installed on one side of the fixed door 20. Multiple limiting frames 23 are fixedly installed on the surface of the filter element housing 1. Each limiting frame 23 has a limiting block 24 inserted inside it. The surfaces of the limiting frames 23 and the limiting blocks 24 are all provided with threaded holes, and bolts 25 are threaded into the threaded holes. Users can observe the usage status of each filter layer inside the filter element through the tempered glass 21 installed on the surface of the fixed door 20, and determine whether the filter element needs to be replaced or the internal components need to be cleaned and maintained. When the filter element needs to be maintained or replaced... When replacing the internal filter material, start the external circulating water pump to pump water in reverse, thereby driving the filtered water to flow in reverse to flush the inside of the filter element, washing away the impurities trapped inside the first support plate 3, the second support plate 4, the third support plate 5, and the fourth support plate 6, so as to restore some of the filtration performance. Then, unscrew the bolts 25 in the threaded holes on the limit frame 23 and the limit block 24 to release the limitation on the fixed door 20. Then, pull the fixed door 20 by the handle 22 to make the sealing strip 19 come out of the sealing groove on the surface of the filter element housing 1, thereby opening the fixed door 20, which facilitates the replacement or cleaning of the internal granular activated carbon 11 and compressed activated carbon 12.

[0031] Working principle of this utility model:

[0032] This utility model is a multi-layer protective water purifier filter element. When using the device, the pipe joint 2 at one end of the filter element housing 1 is connected to the external water inlet pipe, and the pipe joint 2 at the other end of the filter element housing 1 is connected to the external circulating water pump. The external circulating water pump is started so that the water to be filtered flows into the filter element from the pipe joint 2 at one end of the filter element housing 1, ensuring that the water can smoothly enter the filter element housing 1 for treatment.

[0033] After water enters the filter cartridge housing 1, when the water flow impacts the buffer pad 15, the buffer pad 15 can play a role in buffering and shock absorption, reducing the noise generated by the water flow. Moreover, the guide vane 18 can guide the direction of the water flow, so that the water is more evenly distributed inside the filter cartridge, fully contacting each filter layer and improving the filtration efficiency. The support bar 16 and the fixing rod 17 provide installation support for the guide vane 18 to ensure its structural stability.

[0034] Next, the water reaches the first support plate 3, inside which a PP cotton layer 9 is fixedly installed, and a support net 8 is set at the bottom. The support net 8 provides physical support for the PP cotton layer 9 to prevent it from shifting or deforming under the impact of water flow. The PP cotton 9 has a large filter pore size and is mainly used to intercept larger particles in the water, such as silt, rust, and suspended solids. These large particles are blocked by the PP cotton layer 9 and adsorbed on its fiber surface, thereby achieving preliminary purification of the water.

[0035] After being filtered through the PP cotton layer 9, the water enters the second support plate 4. A fixed mesh 10 is installed inside the second support plate 4 via a plug-in connection. The fixed mesh 10 is filled with granular activated carbon 11. The granular activated carbon 11 has a rich porous structure and a large specific surface area. It can remove odors, residual chlorine, and some organic matter from the water through physical adsorption. These harmful substances in the water are adsorbed in the pores of the granular activated carbon, further improving the taste and smell of the water.

[0036] Next, water flows into the third support plate 5, which is also equipped with a fixing mesh 10. However, this fixing mesh 10 is filled with compressed activated carbon 12. Compressed activated carbon 12 is made by compressing activated carbon powder through a special process. Compared with granular activated carbon, it has a more compact structure and higher filtration precision. It can further adsorb residual micro-organic matter, discoloration, odor, etc. in the water, and perform more refined purification of the water quality.

[0037] Water filtered through the first three layers enters the fourth support plate 6, which contains an ultrafiltration membrane layer 13. The ultrafiltration membrane layer 13 has very fine pores, which can trap tiny particles such as bacteria, viruses, colloids, and large organic molecules in the water. The ultrafiltration membrane has high filtration precision, which can effectively improve the hygiene and safety of the water and make the filtered water purer. After being filtered through four layers of PP cotton, granular activated carbon, compressed activated carbon and ultrafiltration membrane, the water becomes clean, safe and tastes good. Finally, it flows out from the pipe connector 2 at the other end of the filter cartridge housing 1 and is available for user use.

[0038] Users can observe the condition of each filter layer inside the filter element through the tempered glass 21 installed on the surface of the fixed door 20, and determine whether the filter element needs to be replaced or the internal components need to be cleaned and maintained. When the filter element needs to be maintained or the internal filter material needs to be replaced, the external circulating water pump is started to pump water in reverse, thereby driving the filtered water to flow in reverse to flush the inside of the filter element, washing away the impurities trapped inside the first support plate 3, the second support plate 4, the third support plate 5 and the fourth support plate 6, so that it can restore a certain filtration performance. Then, the bolts 25 in the threaded holes on the limit frame 23 and the limit block 24 are unscrewed to release the limitation on the fixed door 20. Then, the fixed door 20 is pulled by the handle 22 to make the sealing strip 19 come out of the sealing groove on the surface of the filter element housing 1, thereby opening the fixed door 20, which facilitates the replacement or cleaning of the internal granular activated carbon 11 and compressed activated carbon 12.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
