Description

Technical Field

[0001] This utility model relates to the technical field of reverse osmosis filter cartridges, specifically a reverse osmosis filter cartridge assembly that is easy to assemble and disassemble. Background Technology

[0002] Reverse osmosis (RO) filter cartridges, as core components of water treatment equipment, offer high filtration accuracy and excellent purification effects, and are widely used in household water purifiers and industrial pure water production. Existing RO filter cartridge assemblies mostly employ threaded connections, adhesive bonding, or multi-bolt fastening methods. While these methods ensure sealing performance, they present the problem of cumbersome disassembly and assembly. Disassembly requires specialized tools, and repeated disassembly and assembly can easily lead to wear and tear on the connection points and seal failure. This not only increases the difficulty and maintenance cost for users replacing filter cartridges but may also affect the overall lifespan of the equipment due to improper operation. Furthermore, the structural design of some filter cartridge assemblies does not consider the positioning and guidance requirements during disassembly and assembly, making them prone to installation deviations, which in turn affect the stability of the filtered water flow and purification efficiency. Therefore, there is an urgent need to develop a RO filter cartridge assembly that is simple in structure, easy to operate, precisely positioned, and reliably sealed, addressing the problems of difficult disassembly and assembly, high maintenance costs, and insufficient installation accuracy in existing technologies, thereby improving the user experience and the stability of equipment operation.

[0003] Application number CN202322633594.7 discloses a reverse osmosis filter element assembly that is easy to assemble and disassemble, including a limiting mechanism and a filtering mechanism. The filtering mechanism is snapped into the inside of the limiting mechanism. The limiting mechanism includes a pre-installation unit and a connecting unit. The pre-installation unit is fixedly connected to the surface of the limiting mechanism, and the connecting unit is movably connected to the inside of the pre-installation unit. This easy-to-assemble reverse osmosis filter element assembly is limited inside the outer shell by a bearing shell that drives the filter element assembly to slide and snap into place, allowing for quick fixing and disassembly of the filter element assembly, improving the effectiveness of the device. The pre-installed outer shell and cover plate wrap around and limit the filter element assembly, ensuring even load distribution at all positions. The structure is simple and not easily damaged, and it can also provide a certain degree of protection for the filter element assembly, extending its service life. However, the drawback is that the easy assembly and disassembly of the device refers to the easy assembly and disassembly between the filter element and the outer shell. The outer shell also needs to be connected and installed with the corresponding device. It does not yet provide easy assembly and disassembly support for the assembly between the filter element and the device, which makes the installation of the device still somewhat inconvenient. Utility Model Content

The solution to the problem of easy disassembly and assembly of the device refers to the easy disassembly and assembly of the filter cartridge and the outer shell. However, the outer shell also needs to be connected and installed with the corresponding device. It has not yet been able to provide convenient disassembly and assembly support for the assembly between the filter cartridge and the device. This makes the above devices still have certain inconveniences during installation.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a reverse osmosis filter element assembly that is easy to disassemble and assemble, including a filter element assembly, which is installed inside the filter screen tube assembly, and a convenient disassembly and assembly component is installed on the top of the filter screen tube assembly.

[0007] The convenient assembly and disassembly component includes a second connecting end, the bottom of which is annular, and a spring strip is provided around the bottom circumference of the second connecting end, with a limit block installed at the bottom of the spring strip.

[0008] Furthermore, the filter tube assembly includes a honeycomb filter, which is in the shape of a cylindrical tube. A positioning circular plate is installed on the top of the honeycomb filter, and a connecting end is installed on the top of the positioning circular plate.

[0012] Furthermore, the filter element body includes a porous ceramic body, the outer wall of which is fitted with an aromatic polyamide ultrathin composite membrane, and the outer wall of which is fitted with a reverse osmosis membrane.

[0013] This utility model has the following beneficial effects:

[0014] (1) By installing a convenient assembly and disassembly component on the device, this utility model can provide convenient installation and disassembly when using the device, making the device more convenient to use.

[0015] (2) The honeycomb structure of this utility model forms a uniform force-bearing surface through hexagonal grid, which can directly resist collisions and squeezing during disassembly and assembly (such as accidental knocking during installation or falling during disassembly), prevent damage and deformation of the outer pre-filter layer, or pinholes and cracks in the core reverse osmosis membrane due to external impact, and solve the problem of filtration failure caused by improper disassembly and assembly when the existing filter element is not protected.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Please see Figures 1-4 As shown, this utility model is a reverse osmosis filter element assembly that is easy to disassemble and assemble, including filter element assembly 2, which is installed inside the filter screen tube assembly 1, and a convenient disassembly and assembly component 3 is installed on the top of the filter screen tube assembly 1.

[0026] The easy-to-assemble and disassemble component 3 includes a second connecting end 301. The bottom of the second connecting end 301 is in the shape of a ring. A spring bar 302 is provided on the bottom circumference of the second connecting end 301. A limit block 303 is installed at the bottom of the spring bar 302.

[0027] By installing the easy-installation and disassembly component 3 on the device, the device can be easily installed and disassembled, making it more convenient to use.

[0028] The filter tube assembly 1 includes a honeycomb filter 101, which is in the shape of a round tube. A positioning round plate 102 is installed on the top of the honeycomb filter 101, and a connecting end 103 is installed on the top of the positioning round plate 102.

[0029] The inner wall of the connecting end 103 is provided with an assembly groove 1031 in a circular pattern. The end of the assembly groove 1031 is provided with a limiting slot 1032. The honeycomb filter 101 in the shape of a circular tube intercepts large particles of impurities such as mud and rust in the water to achieve preliminary filtration. The top positioning circular plate 102 helps to fix the inner filter element assembly 2. The assembly groove 1031 and the limiting slot 1032 on the inner wall of the connecting end 103, together with the easy-to-disassemble assembly 3, complete the assembly and fixation.

[0030] The filter element assembly 2 includes a filter element body 201, which is installed on the outside of the filter screen frame 202, which is configured as a circular tube.

[0031] The limiting block 303 is located inside the limiting groove 1032. The bottom elastic bar 302 of the connecting end 2 301 is elastic. The bottom limiting block 303 can slide along the assembly slide groove 1031. When it slides to the limiting groove 1032, the elastic bar 302 rebounds and locks. When disassembling, pressing the elastic bar 302 can disengage it without tools, realizing convenient disassembly and assembly.

[0032] The filter element 201 includes a porous ceramic body 2013, an aromatic polyamide ultrathin composite membrane 2012 installed on the outer wall of the porous ceramic body 2013, a reverse osmosis membrane 2011 installed on the outer wall of the aromatic polyamide ultrathin composite membrane 2012, and a circular tubular filter frame 202 supporting the outer filter element 201. The outer reverse osmosis membrane 2011 of the filter element 201 intercepts small molecule pollutants such as heavy metals and bacteria, the middle aromatic polyamide ultrathin composite membrane 2012 improves the desalination rate, and the inner porous ceramic body 2013 guides the flow, together achieving deep purification.

[0033] This easy-to-assemble and disassemble reverse osmosis filter assembly achieves water treatment through preliminary filtration of the filter tube assembly 1 and deep reverse osmosis purification of the filter element assembly 2. Simultaneously, the convenient disassembly and assembly component 3, structurally coordinated with the filter tube assembly 1, ensures ease of assembly and disassembly. Its specific working principle and process are as follows: In the assembly stage, firstly, the filter element body 201 of the filter element assembly 2 is fitted onto the outside of the filter screen frame 202 (because the filter screen frame 202 is a circular tube, it can stably support the filter element body 201). Next, the assembled filter element assembly 2 is inserted into the inside of the filter tube assembly 1, ensuring that the filter element assembly 2 and the positioning circular plate 102 of the filter tube assembly 1 are in contact to ensure fixed position. Then, the convenient disassembly and assembly component 3 is removed. Assemble component 3 by aligning the limiting block 303 at the bottom of the second connecting end 301 with the assembly groove 1031 of the first connecting end 103 in the filter tube assembly 1. Push the second connecting end 301 to make the limiting block 303 slide along the assembly groove 1031. When the limiting block 303 slides to the limiting slot 1032 at the end of the assembly groove 1031, the spring bar 302 rebounds and drives the limiting block 303 to engage with the limiting slot 1032, completing the fixing of the easy-to-assemble and disassemble component 3 with the filter tube assembly 1. The entire filter element assembly is now assembled. After entering the water purification stage, the filtered water first enters the filter tube assembly 1 and comes into contact with the honeycomb filter 101. Its circular tubular honeycomb structure intercepts large particles of impurities in the water, completing the process. After initial filtration, the water passes through the honeycomb filter 101 and enters the filter element assembly 2 inside the filter tube assembly 1. It then sequentially permeates the reverse osmosis membrane 2011 and the aromatic polyamide ultrathin composite membrane 2012 within the filter element body 201. The reverse osmosis membrane 2011 traps small molecule pollutants in the water, while the aromatic polyamide ultrathin composite membrane 2012 further improves the desalination rate and filtration accuracy. The filtered water finally passes through the porous ceramic body 2013. After being stably guided by the porous ceramic body 2013, the purified water flows out from the connection end 301 of the easy-to-disassemble component 3, completing the entire water purification process. When it is necessary to disassemble and replace the component for filter element maintenance, first press the easy-to-disassemble component 3. The bottom spring bar 302 deforms and causes the limiting block 303 to disengage from the limiting slot 1032. Then, the easy-to-disassemble component 3 is pulled out upward along the assembly slide 1031 of the connecting end 103. The old filter element component 2 is then taken out from the inside of the filter tube component 1 and replaced with a new filter element component 2 with the filter element body 201 fitted on the outside of the filter frame 202 in advance. Finally, the steps of aligning the connecting end 2 301 with the assembly slide 1031 and pushing the limiting block 303 into the limiting slot 1032 are repeated in the component assembly stage. The easy-to-disassemble component 3 is then reinstalled, and the filter element replacement and component reset are completed. The whole process does not require any additional tools, which fully reflects the functional advantages of "easy disassembly and assembly".
