Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a filter element assembly for a water purification device that is easy to disassemble and clean. Background Technology

[0002] The filter cartridge of a water purifier is the core filtration component of a water purification system. It is mainly used to intercept, adsorb, or decompose impurities and pollutants in the water to ensure the quality of the output water. It is usually made of different materials such as activated carbon, PP cotton, ultrafiltration membrane, and RO reverse osmosis membrane. Different materials correspond to different filtration functions: PP cotton can filter out large particles of impurities such as sediment and rust; activated carbon can adsorb residual chlorine, odors, and some organic matter; ultrafiltration membrane and RO membrane can further remove tiny pollutants such as bacteria, viruses, and heavy metal ions. The filter cartridge needs to be replaced regularly. Its filtration effect and service life directly determine the water purification capacity of the water purifier and are key components to ensure drinking water safety.

[0003] A search revealed that the document with publication number "CN215439709U" states, "This utility model discloses a filter element assembly and a water purification device, relating to the field of water purification technology." In use, the filter element assembly includes an inlet pipe, a filter unit wound around the inlet pipe, and a housing. Raw water enters the filter unit from the inside through the inlet pipe and exits from the circumferential side of the filter unit. The resulting pure water exits through a first flow channel located between the circumference of the filter unit and the housing, and the resulting wastewater exits through a second flow channel located between the second end of the filter unit and the housing. The pure water outlet is on the circumference of the filter unit, while the wastewater outlet is at the end of the filter unit. This allows for adjusting the volumes of the first and second flow channels to increase the pure water capacity and decrease the wastewater capacity of the filter element assembly.

[0004] However, when cleaning filter cartridges, traditional filter cartridges often use a simple plug-in structure with screw fixing. However, during use, it is not easy to pull the filter cartridge out of the shell due to friction and water residue. Furthermore, the filter cartridge is prone to instability during installation and use due to the lack of proper positioning and support. In addition, the filter cartridge lacks a certain self-cleaning mechanism, and impurities easily accumulate on the surface of the filter cartridge, requiring manual washing. Impurities also easily accumulate and adhere to the inner wall of the shell.

[0005] Therefore, we provide a water purification equipment filter cartridge assembly that is easy to disassemble and clean to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: A water purifier filter cartridge assembly that is easy to disassemble and clean includes a water purifier body. A filter cartridge connection port is provided on the lower side of the water purifier body. A filter cartridge disassembly and cleaning assembly is provided on the lower side of each filter cartridge connection port. The filter cartridge disassembly and cleaning assembly includes an adsorption magnet located at the top inner side of the filter cartridge connection port. A filter cartridge body is installed in the middle inner side of the filter cartridge connection port. A magnetic adsorption plate is provided at the top of the filter cartridge body. A rotating spiral wall-scraping pad is provided on the outer side of the filter cartridge body. A wall-scraping pad is provided at the lower outer end of the filter cartridge body. A filter cartridge push plate is provided on the lower side of the filter cartridge body. A push plate spring is provided on the lower side of the filter cartridge push plate. A filter cartridge outer sleeve is provided on the outer side of the rotating spiral wall-scraping pad.

[0007] As a further description of the above technical solution: The adsorption magnet and the filter element connection port are bonded together. The adsorption magnet is a neodymium iron boron magnet, and the magnetic adsorption plate is made of 430 ferritic stainless steel. Both the adsorption magnet and the magnetic adsorption plate are annular structures of the same diameter.

[0008] As a further description of the above technical solution: The rotating spiral wall scraping pad is connected to the filter element body by a slot. The rotating spiral wall scraping pad is made of silicone. Both the upper and lower ends of the rotating spiral wall scraping pad have stainless steel fixing rings. The inside of the rotating spiral wall scraping pad is tightly fitted to the filter element body, and the outside of the rotating spiral wall scraping pad is tightly fitted to the inner wall of the filter element outer sleeve.

[0009] As a further description of the above technical solution: The scraping pad is bonded to the filter element body, and the scraping pad is tightly fitted to the inner wall of the filter element outer sleeve.

[0010] As a further description of the above technical solution: The push plate spring is bonded to the inner bottom of the filter element outer sleeve, and the push plate spring and the filter element body form an elastic limiting structure through the filter element push plate.

[0011] As a further description of the above technical solution: The filter element outer sleeve and the filter element connection port are connected by threads, and the inner wall of the filter element outer sleeve is a food-grade ceramic nano-coating.

[0012] As a further description of the above technical solution: The surface of the filter element jacket is provided with a hexagonal shell, which is hexagonal in shape and has rounded chamfered edges.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a filter cartridge disassembly and cleaning assembly. When needed, the user inserts the filter cartridge body into the filter cartridge connection port. At this time, the magnetic adsorption plate on the upper surface of the filter cartridge body will be attracted together with the adsorption magnet, so that the filter cartridge body and the water outlet in the filter cartridge connection port are tightly fitted together. When it is necessary to remove the filter cartridge outer sleeve, the filter cartridge body can also be fixed by its own attraction, and only the filter cartridge outer sleeve needs to be pulled out, which facilitates disassembly. When the filter cartridge body is inserted into the filter cartridge outer sleeve, the push plate spring will be subjected to pressure and undergo elastic deformation. At the same time, the filter cartridge push plate applies an upward supporting force to the filter cartridge body, thereby achieving stable positioning of the filter cartridge body inside the filter cartridge outer sleeve and increasing the stability of the magnetic connection between the magnetic adsorption plate and the adsorption magnet.

[0014] 2. This utility model utilizes a filter element disassembly and cleaning assembly. When the filter element outer sleeve is placed over the filter element body, as it is pushed inward, the rotating spiral scraping pad on the outside of the filter element body will adhere to the inner wall of the filter element outer sleeve. As the filter element body is inserted into the filter element outer sleeve, the rotating spiral scraping pad will scrape the surface of the filter element body due to friction, thus cleaning the surface of the filter element body. Due to friction, the rotating spiral scraping pad will rotate to a certain extent, thereby improving the cleaning effect. As the filter element body is pulled out from the filter element outer sleeve, the scraping pad will scrape the outer wall of the filter element outer sleeve, thereby removing impurities attached to the outer wall of the filter element outer sleeve and maintaining the overall cleanliness and hygiene of the filter element.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 As shown, this utility model provides a technical solution: a filter element assembly for a water purifier that is easy to disassemble and clean, including a water purifier body 1, a filter element connection port 2 provided on the lower side of the water purifier body 1, a filter element disassembly and cleaning assembly 3 provided on the lower side of the filter element connection port 2, the filter element disassembly and cleaning assembly 3 including an adsorption magnet 301 provided on the top of the inner side of the filter element connection port 2, a filter element body 302 installed in the middle of the inner side of the filter element connection port 2, a magnetic adsorption plate 303 provided on the top of the filter element body 302, a rotating spiral wall scraping pad 304 provided on the outer side of the filter element body 302, a wall scraping pad 305 provided on the lower outer end of the filter element body 302, a filter element push plate 306 provided on the lower side of the filter element body 302, a push plate spring 307 provided on the lower side of the filter element push plate 306, and a filter element outer sleeve 4 provided on the outer side of the rotating spiral wall scraping pad 304.

[0019] Furthermore, the adsorption magnet 301 and the filter element connection port 2 are bonded together. The adsorption magnet 301 is a neodymium iron boron magnet, and the magnetic adsorption plate 303 is 430 ferritic stainless steel. Both the adsorption magnet 301 and the magnetic adsorption plate 303 are annular structures of the same diameter. When needed, the user inserts the filter element body 302 into the filter element connection port 2. At this time, the magnetic adsorption plate 303 on the upper surface of the filter element body 302 will be attracted together with the adsorption magnet 301, so that the filter element body 302 is tightly attached to the water outlet in the filter element connection port 2. When it is necessary to remove the filter element outer sleeve 4, the filter element body 302 can also be fixed by its own attraction, and only the filter element outer sleeve 4 can be pulled out, thus facilitating disassembly.

[0020] Furthermore, the rotating spiral scraping pad 304 is connected to the filter element body 302 via a slotted connection. The rotating spiral scraping pad 304 is made of silicone and has stainless steel fixing rings at both ends. The inside of the rotating spiral scraping pad 304 fits tightly with the filter element body 302, and the outside of the rotating spiral scraping pad 304 fits tightly with the inner wall of the filter element outer sleeve 4. When the filter element outer sleeve 4 is put on the filter element body 302, as it is pushed inward, the rotating spiral scraping pad 304 on the outside of the filter element body 302 will fit together with the inner wall of the filter element outer sleeve 4. As the filter element body 302 is inserted into the filter element outer sleeve 4, the rotating spiral scraping pad 304 will scrape the surface of the filter element body 302 due to friction, thus cleaning the surface of the filter element body 302. Due to the friction, the rotating spiral scraping pad 304 will rotate to a certain extent, thereby improving the cleaning effect.

[0021] Furthermore, the scraping pad 305 is bonded to the filter element body 302, and the scraping pad 305 is tightly fitted to the inner wall of the filter element outer sleeve 4. When needed, as the filter element body 302 is pulled out from the filter element outer sleeve 4, the scraping pad 305 will scrape the outer wall of the filter element outer sleeve 4, thereby removing impurities attached to the outer wall of the filter element outer sleeve 4 and keeping the filter element clean and hygienic.

[0022] Furthermore, the push plate spring 307 is bonded to the bottom of the inner side of the filter element outer sleeve 4. The push plate spring 307 and the filter element body 302 form an elastic limiting structure through the filter element push plate 306. When the filter element body 302 is inserted into the filter element outer sleeve 4, the push plate spring 307 will be subjected to pressure and undergo elastic deformation. At the same time, the filter element push plate 306 applies an upward supporting force to the filter element body 302, thereby achieving stable limiting of the filter element body 302 in the filter element outer sleeve 4 and increasing the stability of the magnetic attraction connection between the magnetic adsorption plate 303 and the adsorption magnet 301.

[0023] Furthermore, the filter cartridge outer sleeve 4 and the filter cartridge connection port 2 are connected by threads. The inner wall of the filter cartridge outer sleeve 4 is a food-grade ceramic nano-coating. When in use, the food-grade ceramic nano-coating on the inner wall of the filter cartridge outer sleeve 4 can effectively reduce the frictional resistance when water flows through. In addition, the food-grade ceramic nano-coating has good corrosion resistance and antibacterial properties, which can effectively prevent bacteria from growing inside the filter cartridge and reduce the adhesion of impurities.

[0024] Furthermore, the surface of the filter element outer sleeve 4 is provided with a hexagonal shell 5. The hexagonal shell 5 is hexagonal in shape and has rounded chamfered edges. When it is necessary to disassemble or install the filter element outer sleeve 4, the hexagonal structure of the hexagonal shell 5 can provide a good grip and anti-slip effect. At the same time, its rounded chamfered design avoids the concentration of pressure on local areas of the palm during operation, and no external equipment is required to provide assistance, thus facilitating disassembly and cleaning.

[0025] Working principle: When needed, connect the water purifier body 1 to the pipe. After a period of use, unscrew the filter cartridge sleeve 4 from the filter cartridge connection port 2, and then pull the filter cartridge sleeve 4 outward along the filter cartridge body 302. The adsorption magnet 301 will then firmly adhere and fix the filter cartridge body 302 through the magnetic adsorption plate 303. At this time, the scraping pad 305 under the filter cartridge body 302 will scrape and clean the inner wall of the filter cartridge sleeve 4. Then rinse the scraping pad 305. After rinsing, reinsert the filter cartridge sleeve 4 into the filter cartridge body 302 and push it inward. At this time, the rotating spiral scraping pad 304 will be fixed to the opening position of the filter cartridge sleeve 4 by friction. Squeezing and rotating the spiral scraping pad 304 will wipe and clean the outer surface of the filter element body 302. After repeating this several times, the filter element outer sleeve 4 is pulled out again, and then the filter element body 302 is removed from the adsorption magnet 301. The filter element body 302 is rinsed, and then the filter element body 302 is installed back onto the adsorption magnet 301. After it is fixed, the operator uses the hexagonal shell 5 to put the filter element outer sleeve 4 back into the filter element connection port 2. During this process, the push plate spring 307 will press the filter element body 302 tightly against the adsorption magnet 301 through the filter element push plate 306 for fixing and supporting the limit. This completes the use process of a water purification equipment filter element assembly that is easy to disassemble and clean.

[0026] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
