[0016] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a technical solution: An activated carbon fiber filter cartridge water purifier module is assembled from an outer cylinder 1, a filter cartridge 4, an upper cover 2, and a lower cover 3 (the outer cylinder 1, upper cover 2, and lower cover 3 are standardized components). Through the precise cooperation of each component, it achieves efficient filtration and convenient disassembly and assembly, solving the problem of disassembling pipelines when replacing filter cartridges in existing water purifiers.

[0018] The upper cover 2 is positioned at the upper opening of the outer cylinder 1 to seal the opening, while the lower cover 3 is positioned at the lower opening of the outer cylinder 1 to seal the opening. The filter element 4 is detachably connected to the upper cover 2 at its upper end and to the lower cover 3 at its lower end. With the cooperation of the upper cover 2 and the lower cover 3, it is stably installed in the inner cavity of the outer cylinder 1. A gap (annular cavity gap) is naturally formed between the outer wall of the filter element 4 and the inner wall of the outer cylinder 1 to allow water to flow through. The filter element 4 also has a core hole 5 along its axial direction in the middle. The upper cover 2 has an inlet 23 for water to enter the gap, and the lower cover 3 has an outlet 25 connected to the core hole 5. The water in the gap is filtered by the filter element 4 and discharged through the outlet 25.

[0019] The upper cover 2 is specifically composed of an upper top cover 201 and an upper plug 202, which are either integrally fixed or separately. The top edge of the outer cylinder 1 extends outward to form an annular upper folded edge 16. An annular groove is provided on the outer peripheral wall of the upper plug 202, and a third sealing ring 15 is embedded in the annular groove. During assembly, the upper plug 202 is inserted into the upper opening of the outer cylinder 1 from top to bottom until the lower surface of the upper top cover 201 is tightly fitted and pressed against the upper folded edge 16 at the top of the outer cylinder 1. The third sealing ring 15 is used to seal the outer cylinder 1. The interference fit of the inner wall achieves a seal between the upper cover 2 and the outer cylinder 1. To further enhance the connection tightness, an annular upper outer ring groove 17 is also provided on the outer wall of the upper cover 201. The position of the upper outer ring groove 17 corresponds to the upper folded edge 16 on the top of the outer cylinder 1. After assembly, the upper clamp 18 is fitted onto the outside of the upper outer ring groove 17 and the upper folded edge 16. By tightening the upper clamp 18, the connection between the upper cover 201 and the upper folded edge 16 is more stable, preventing loosening during long-term use. In addition, the bottom of the upper cover 2 (i.e., the bottom of the upper plug 202) is provided with a downwardly recessed insertion interface 11. The inner wall of the insertion interface 11 is also provided with an annular groove, in which a first sealing ring 12 is embedded for sealing connection with the upper end of the filter element 4.

[0020] The structure of the lower cover 3 corresponds to that of the upper cover 2. It is composed of an integrated or separate lower top cover 301 and a lower plug 302. The bottom edge of the outer cylinder 1 extends outward to form an annular lower folded edge. An annular groove is provided on the outer peripheral wall of the lower plug 302, and a fourth sealing ring 19 is embedded in the groove. During assembly, the lower plug 302 is inserted into the lower opening of the outer cylinder 1 from bottom to top until the upper surface of the lower top cover 301 is tightly fitted and pressed against the lower folded edge at the bottom of the outer cylinder 1. The seal between the lower cover 3 and the outer cylinder 1 is achieved through the interference fit between the fourth sealing ring 19 and the inner wall of the outer cylinder 1. Similarly, an annular lower outer ring groove 21 is provided on the outer wall of the lower top cover 301. The lower outer ring groove 21 corresponds to the lower folded edge at the bottom of the outer cylinder 1. After assembly, the lower clamp 22 is fitted on the outside of the lower outer ring groove 21 and the lower folded edge, and the lower clamp 22 is tightened to enhance the connection between the lower cover 3 and the outer cylinder 1. Meanwhile, a docking hole 13 is provided on the top of the lower cover 3 (i.e. the top of the lower plug 302), and an annular groove is provided on the inner wall of the docking hole 13. A second sealing ring 14 is embedded in the groove to achieve a sealed connection with the lower end of the filter element 4.

[0021] The filter element 4, as the core filtration component, is assembled from the core cylinder 401, the upper pressure cover 402 and the lower pressure cover 403. The core cylinder 401 is made of activated carbon fiber material, and its interior is hollow to form the aforementioned core holes 5. The upper pressure cap 402 is assembled on the top of the core cylinder 401. The outer periphery of the upper pressure cap 402 extends outward to form an annular upper outer edge 6. The upper outer edge 6 covers the top edge of the core cylinder 401 from top to bottom. The upper pressure cap 402 is fixed to the top of the core cylinder 401 by adhesive or snap-fit. The top of the upper pressure cap 402 protrudes upward to form a cylindrical insertion post 7. The diameter of the insertion post 7 is adapted to the diameter of the bottom insertion interface 11 of the upper cover 2. During assembly, the insertion post 7 is inserted into the insertion interface 11. The first sealing ring 12 in the insertion interface 11 is used to seal the upper end of the filter element 4 and the upper cover 2. At the same time, the bottom end of the insertion post 7 extends downward and is inserted into the core hole 5 in the middle of the core cylinder 401, which plays the role of positioning the core hole 5. In addition, the top surface of the upper pressure cap 402 also protrudes upward to form an annular spacer ring 8. The spacer ring 8 is located outside the insertion post 7. After the filter element 4 and the upper cap 2 are assembled, the top of the spacer ring 8 is tightly abutted against the bottom outer edge of the insertion interface 11, thereby forming a flow guiding structure at the opening on the outer cylinder 1. This ensures that after the external water enters from the inlet 23, it can be accurately guided to the gap between the core cylinder 401 and the inner wall of the outer cylinder 1, preventing water from being lost through other gaps.

[0022] The lower pressure cap 403 is assembled at the bottom end of the core cylinder 401. The outer periphery of the lower pressure cap 403 extends outward to form an annular lower outer edge 9, which covers the bottom edge of the core cylinder 401 from bottom to top. The lower pressure cap 403 is fixed to the bottom end of the core cylinder 401 by adhesive or snap-fit. The bottom of the lower pressure cap 403 protrudes downward to form a cylindrical water outlet channel 10. The diameter of the water outlet channel 10 is adapted to the diameter of the mating hole 13 at the top of the lower sealing cap 3. During assembly, the water outlet channel 10 is... The lower end is inserted into the docking hole 13, and the second sealing ring 14 in the docking hole 13 is used to seal the lower end of the filter element 4 and the lower cover 3. At the same time, the top of the water outlet channel 10 extends upward and is inserted into the core hole 5 in the middle of the core cylinder 401, so that the core hole 5 is connected to the water outlet channel 10. The water outlet 25 of the lower cover 3 is opened at the bottom of the lower cover 302 and is connected to the docking hole 13, thus forming a water outlet path of "core hole 5 → water outlet channel 10 → docking hole 13 → water outlet 25".

[0023] To facilitate connection with external water supply pipelines, the inlet 23 on the upper cover 2 is machined with internal threads, and is also equipped with a connecting elbow 24 with external threads. The connecting elbow 24 is screwed onto the inlet 23 through threaded engagement. In actual use, the angle of the connecting elbow 24 can be adjusted according to the direction of the external pipeline to improve installation flexibility, or a tee pipe or other connectors can be used to connect with the external pipeline according to the specific usage.

[0024] Furthermore, this utility model is a set of carbon fiber filter cartridge water purifier modules. When a large amount of water needs to be filtered, multiple sets of carbon fiber filter cartridge water purifier modules can be connected in parallel or a large-size carbon fiber filter cartridge water purifier module can be used to achieve the filtration of a large amount of water.

[0025] In summary, this specific embodiment achieves modular assembly of the water purifier module by clearly defining the positional relationship and connection method of each component. The detachable and sealed connection between the filter element 4 and the upper and lower covers 3 allows the filter element 4 to be removed without disassembling the external pipeline when replacing the filter element, which is convenient as only the upper and lower covers 3 need to be removed. At the same time, the setting of multiple sealing rings and the reinforcement of the clamps ensure the overall sealing and structural stability of the module, while the flow guiding design of the spacer ring 8 ensures filtration efficiency. This effectively solves the problem of troublesome filter element replacement in the prior art and meets the needs of humanized use.
