[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0025] See Figures 1-8 A water purifier with an integrated filter cartridge shell includes a main body 1 and a filter material 2 disposed in the main body 1. The filter cartridge shell 101 is integrally formed in the main body 1, and the main body 1 and the filter cartridge shell 101 form an inseparable whole. The filter material 2 is installed in the filter cartridge shell 101. The filter cartridge housing 101 has an integrally formed inlet end and outlet end that cooperate with the filter material; A detachable connection and mating part is provided between the filter material 2 and the filter element shell 101, and the filter material 2 is detachably installed in the filter element shell 101 through the detachable connection and mating part; The filter housing 101 has an opening facing the upper part of the main body 1, so that the filter material 2 can be installed and removed from the upper part of the main body 1.

[0026] This design, by integrally molding the filter cartridge housing 101 within the main body 1, forms an unremovable whole with the main body 1, completely solving the core pain point of the prior art where separate filter cartridges require double disassembly. In the prior art, the outer shell of a separate filter cartridge needs to be removed from the water purifier first, and then the outer shell needs to be opened to replace the filter media, which is cumbersome, time-consuming, and laborious. In this solution, the filter media 2 is directly installed inside the integrally molded filter cartridge housing 101, eliminating the need to disassemble the filter cartridge housing first. Cleaning or replacement can be completed simply by removing the filter media 2 from the filter cartridge housing 101, greatly simplifying the operation process, reducing user operation steps and time costs, and improving the convenience of filter media maintenance. Meanwhile, in the background technology, the split filter cartridge requires a special fixing structure for installing the outer shell inside the water purifier, which increases the complexity of the internal structure of the water purifier and the difficulty of production and assembly. In this solution, the filter cartridge shell 101 is integrally formed with the main body 1, eliminating the need for an additional outer shell installation fixing structure. This simplifies the internal structure of the main body 1, reduces the number of parts and assembly steps in the production process, reduces the risk of assembly errors or loosening caused by additional fixing structures, and thus extends the overall service life of the water purifier.

[0027] The existing filter media 2 are generally of fixed specifications and models. This technical solution addresses these filter media 2 by integrally molding a filter element shell 101 from the main body 1. The main body 1 has three filter element shells 101 arranged linearly at intervals, or, according to customer order requirements, the main body 1 has only one filter element shell 101.

[0028] The main body 1 has a connecting section 102 for installing the filter cover 3 at the opening of the filter element shell 101. The connecting section 102 extends upward along the upper part of the filter element shell 101 and is fixedly connected to the filter cover 3. The filter cover 3, the connecting section 102 and the filter element shell 101 form a sealed mounting cavity 103 for encapsulating the filter material 2, and a sealing structure 4 is provided between the filter cover 3 and the connecting section 102 to prevent liquid from leaking into the sealed mounting cavity 103.

[0029] An upward-extending connecting section 102 is provided inside the main body 1 at the opening of the filter cartridge shell 101, and the filter cover 3 is fixedly connected to the connecting section 102 to form a sealed installation cavity 103 for encapsulating the filter material 2. When the filter material 2 needs to be replaced or cleaned, only the filter cover 3 needs to be removed. The upward extension of the connecting section 102 along the upper part of the filter cartridge shell 101 provides a reasonable installation space and connection base for the filter cover 3, making the installation position of the filter cover 3 easier to operate. When removing or installing the filter cover 3, users do not need to go deep into the complex areas inside the main body 1, further improving the convenience of filter material 2 maintenance. In addition, the sealing structure 4 provided between the filter cover 3 and the connecting section 102 is specifically designed to prevent liquid from leaking into the sealed installation cavity 103, effectively avoiding water leakage problems caused by poor sealing between the filter cover 3 and the connecting section 102, reducing the risk of damage to other internal components of the main body 1 caused by water leakage, extending the overall service life of the water purifier, and avoiding safety hazards and user inconvenience caused by water leakage, thus improving the user experience. The sealing structure 4 includes a first sealing ring 401 disposed between the filter cover 3 and the connecting section 102. The filter cover 3 is provided with a first sealing groove 301 for installing the first sealing ring 401. When the filter cover 3 is fixedly connected to the connecting section 102, the first sealing ring 401 abuts against the connecting section 102 and the first sealing groove 301, and the first sealing ring 401 forms a first longitudinal seal between the filter cover 3 and the connecting section 102. The sealing structure 4 also includes a second sealing ring 402 disposed between the filter cover 3 and the connecting section 102. The connecting section 102 is provided with a second sealing groove 104 for installing the second sealing ring 402. When the filter cover 3 and the connecting section 102 are fixedly connected, the second sealing ring 402 abuts against the filter cover 3 and the second sealing groove 104, and the second sealing ring 402 forms a second transverse seal between the filter cover 3 and the connecting section 102.

[0030] The sealing structure 4 adopts a double-sealing design, with a first longitudinal seal formed by a first sealing ring 401 and a second transverse seal formed by a second sealing ring 402. This strengthens the sealing performance between the filter cover 3 and the connecting section 102 from different directions and dimensions, completely solving the sealing failure problem that may exist with a single seal. The first sealing ring 401 is installed in the first sealing groove 301 of the filter cover 3. When the filter cover 3 is fixed to the connecting section 102, the first sealing ring 401 abuts against the connecting section 102 and the first sealing groove 301, forming a longitudinal seal that effectively prevents liquid leakage along the longitudinal gap between the filter cover 3 and the connecting section 102. The second sealing ring 402 is installed in the second sealing groove 104 of the connecting section 102, abutting against the filter cover 3 and the second sealing groove 104, forming a transverse seal that further prevents liquid leakage along the transverse gap. The sealing reliability is greatly improved. Even if one seal experiences slight wear due to long-term use, the other seal can still function, preventing immediate leakage and extending the overall service life of the sealing structure. Meanwhile, the first sealing groove 301 and the second sealing groove 104 provide stable installation positions for the first sealing ring 401 and the second sealing ring 402, respectively, preventing displacement or detachment of the sealing rings during installation or use, and ensuring the stability of the sealing effect. Furthermore, this dual-seal design eliminates the need for additional complex sealing components. Through a reasonable groove design and the cooperation of the dual sealing rings, it improves sealing performance without significantly increasing production and assembly costs, balancing reliability and economy, and further enhancing the market competitiveness of the water purifier.

[0031] A threaded connection structure 5 is provided between the filter cover 3 and the connecting section 102. The filter cover 3 is detachably installed on the connecting section 102 of the body 1 through the threaded connection structure 5.

[0032] The filter cover 3 has an internal thread, and the connecting section 102 has an external thread. The filter cover 3 is installed on the connecting section 102 by means of threaded fixation and disassembly.

[0033] The threaded connection structure 5 has a simple structure and low manufacturing difficulty. The external thread can be processed and formed synchronously with the connecting section 102 of the main body 1, and the internal thread can be processed and formed synchronously with the filter cover 3. There is no need to add complicated parts or assembly processes, which reduces the production cost. At the same time, the threaded connection has a certain locking force, which can ensure the connection stability and reliability of the filter cover 3 and the connecting section 102 for a long time, further extending the overall service life of the water purifier. The main body 1 has an integrally formed partition plate 105 for assisting in the positioning and installation of the filter cover 3. The partition plate 105 is connected to the upper part of the filter element shell 101. The connecting section 102 protrudes upward and is disposed on the partition plate 105. After the filter cover 3 is fixed to the connecting section 102, the bottom of the filter cover 3 abuts against the partition plate 105.

[0034] A partition plate 105 is integrally formed within the main body 1 and is connected to the upper part of the filter element shell 101. A connecting section 102 protrudes upward from the partition plate 105, providing precise auxiliary positioning for the installation of the filter cover 3. The upward protrusion of the connecting section 102 on the partition plate 105 increases the connection area between the connecting section 102 and the filter cover 3. Through the support and limiting of the partition plate 105, it is ensured that the filter cover 3 is in the correct position every time it is installed, avoiding the ineffective cooperation of the sealing structure 4 due to installation misalignment, thereby preventing problems such as poor sealing and water leakage, and improving the accuracy and consistency of filter cover 3 installation. Secondly, the integral forming of the partition plate 105 with the main body 1 can enhance the overall structural strength of the main body 1. The setting of the partition plate 105 can also reasonably divide the internal space of the main body 1, isolating the filter cover 3 installation area from other component areas to a certain extent, reducing the interference of other components on the installation and disassembly of the filter cover 3, and improving the convenience of operation.

[0035] An inner side plate 106 is integrally formed on the inner side of the main body 1 corresponding to the first end of the partition plate 105. A front panel 107 is integrally formed on the outer side of the main body 1 corresponding to the second end of the partition plate 105. A top plate 108 is integrally formed on the upper part of the main body 1 corresponding to the top of the partition plate 105. A partition cavity 109 with openings on the left and right sides is formed between the partition plate 105, the inner side plate 106, the front panel 107 and the top plate 108. The top plate 108 is provided with a disassembly and assembly opening 110 for disassembling and installing the filter cover 3. The main body 1 is equipped with an adjustment tool 9 on its exterior, which is used to assist in the installation and removal of the filter cover 3. A positioning structure 10 is provided between the adjustment tool 9 and the filter cover 3, and the adjustment tool 9 is positioned and sleeved around the filter cover 3 through the positioning structure 10.

[0036] The design of the disassembly opening 110 allows users to remove and install the filter cover 3 without disassembling the entire outer shell of the main body 1, simplifying the cleaning and replacement process of the filter media 2. The inner side panel 106, front panel 107, and top panel 108 are integrally formed with the main body 1, further enhancing the overall structural stability of the main body 1. Furthermore, the adjustment tool 9 externally mounted on the main body 1 is specifically designed for the installation and removal of the filter cover 3, solving the problem of insufficient hand strength or excessively tight screw-on filter cover 3, thus improving ease of operation and applicability. The positioning structure 10 between the adjustment tool 9 and the filter cover 3 ensures that the adjustment tool 9 is precisely fitted around the filter cover 3, preventing slippage or displacement during use. This ensures that force is effectively transmitted to the filter cover 3, improving the efficiency and safety of installation and removal operations, preventing hand injuries or damage to the filter cover 3 due to displacement of the adjustment tool 9, and further enhancing the user experience. The design of openings on both sides of the partition cavity 109 also provides a basis for the subsequent installation of side plates, making it easy to achieve airtight protection of the partition cavity 109, and taking into account both ease of operation and component protection.

[0037] The positioning structure 10 includes grooves arranged in a circumferential array on the outer periphery of the filter cover 3, and protrusions arranged in a circumferential array on the outer periphery of the adjusting tool 9. The protrusions are inserted into the grooves, and the adjusting tool 9 is positioned and sleeved around the filter cover 3.

[0038] The main body 1 is provided with a partition cavity 109. The two sides of the cavity are provided with a first side plate 6 and a second side plate 7 respectively. The inner side of the first side plate 6 is sealed and abuts against the first side of the partition plate 105, and the inner side of the second side plate 7 is sealed and abuts against the second side of the partition plate 105. The top opening of the partition cavity 109 is provided with a top cover 8 so that the partition cavity 109 forms a relatively sealed cavity. The first side plate 6 and / or the second side plate 7 and / or the top cover 8 are detachably installed on the main body 1.

[0039] The inner side of the first side plate 6 is sealed against the first side of the partition plate 105, and the inner side of the second side plate 7 is sealed against the second side of the partition plate 105, further improving the sealing performance of the partition cavity 109 and preventing contaminants from entering through the gap between the side plate and the partition plate 105. When it is necessary to clean or replace the filter material 2, the user can first remove the top cover 8 and operate the filter element cover 3 through the disassembly opening 110 on the top plate 108. After the operation is completed, the top cover 8 and the filter element cover 3 can be reinstalled, which takes into account both protection and ease of operation.

[0040] The top cover 8 is detachably installed on the main body 1 using clips or screws. Taking a main body 1 with only one filter cartridge shell 101 as an example, since the filter cartridge shell 101 is integrally formed with the main body 1, the main body 1 integrally forms a first water channel and a second water channel. The outlet end of the first water channel corresponds to the input end of the filter media (the input end of the filter media is a plug-in end positioned inside the filter cartridge shell 101), and the inlet end of the second water channel is connected to the output end of the filter media. The outlet end of the second water channel is connected to the water outlet of the water purifier.

[0041] The inner edge of the disassembly opening 110 is provided with a guard 111 for preventing hand scratches. The guard 111 has a closed-loop structure and extends downward toward the disassembly opening 110 to form a first reinforcing structure that increases mechanical strength.

[0042] A closed-loop retaining edge 111 is provided on the inner edge of the disassembly opening 110, and the retaining edge 111 extends downwards towards the disassembly opening 110, solving the problem of potential hand scratches at the edge of the disassembly opening 110. If the edge of the water purifier's opening is not treated, it is prone to sharp corners, which may cut the user's hands during operation. The retaining edge 111 in this solution can smooth the inner edge of the disassembly opening 110, preventing the user's hands from directly contacting the edge of the opening and being scratched when installing or removing the filter cover 3 and handling the filter material 2 through the disassembly opening 110, significantly improving operational safety and ensuring the user's personal safety during use. Secondly, the retaining edge 111 extends downwards to form a first reinforcing structure, which can effectively enhance the mechanical strength of the top plate 108 in the area surrounding the disassembly opening 110.

[0043] The lower part of the guard 111 is provided with a flange 112 for preventing hand scratches. The flange 112 has a closed-loop structure and extends laterally toward the partition cavity 109 to form a second reinforcing structure that increases mechanical strength.

[0044] A closed-loop flange 112 extending laterally toward the partition cavity 109 is provided at the lower part of the retaining edge 111, which further enhances the anti-scratch effect. Although the retaining edge 111 can protect the inner edge of the disassembly opening 110, there may still be a potential risk of scratching hands at the lower edge of the retaining edge 111. The laterally extending structure of the flange 112 can smooth the lower edge of the retaining edge 111.

[0045] The flange 112 has a plurality of reinforcing ribs 113 on its side, which are arranged in a circumferentially spaced array along the side of the flange 112. A slot 114 is provided between the reinforcing ribs 113 and the top plate 108. The main body 1 has a first side plate 6 and a second side plate 7 on both sides. Each side plate has a limiting part 11 embedded in the slot 114 on its inner side. Each side plate has a first buckle 12 that is fastened to the main body 1 on its upper inner side and a second buckle 13 that is fastened to the main body 1 on its lower inner side.

[0046] The reinforcing rib 113 increases the mechanical strength of the flange 112 and can also be used to position and install the side plate using the slot 114 between the reinforcing rib 113 and the plate 108.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
