Detailed Description of the Invention

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-5 , the present utility model provides the following technical solutions:

[0028] A filter element device that is convenient for replacement, including a filter element body 1, a connection mechanism 2 fixedly connected to the surface of the filter element body 1, and a sealing mechanism 3 fixedly connected to the top of the connection mechanism 2;

[0029] The connection mechanism 2 includes a filter element shell 21, a clamping groove 22, a fixing hole 23 and a fixing ring 24. The filter element shell 21 is fixedly connected to the surface of the filter element body 1. The clamping groove 22 is opened at the top inside the filter element shell 21. The fixing hole 23 is opened at the bottom inside the clamping groove 22. The fixing ring 24 is fixedly connected to the inside of the fixing hole 23.

[0030] In this embodiment: By providing the filter element body 1, impurities, pollutants, etc. in the fluid can be effectively removed, providing clean and safe fluid for users. The filter element housing 21 fixed on the surface of the filter element body 1 provides external protection for the filter element body 1, preventing the filter element from being damaged by external impacts, abrasions, etc. during transportation, installation, and use. At the same time, as the carrier of the connection and sealing mechanism 3, it enables the filter element to be stably connected to the sealing mechanism 3, ensuring the integrity and reliability of the entire filter element device. By providing the clamping groove 22 opened at the inner top of the filter element housing 21, it provides a convenient way for connection with the sealing mechanism 3. By clamping with the corresponding components of the sealing mechanism 3, rapid installation and disassembly can be achieved, facilitating users to replace the filter element. Moreover, the design of the clamping groove 22 can ensure the accurate position of the sealing mechanism 3 during installation, guaranteeing the sealing performance and stability of the connection. By providing the fixing hole 23, it provides an additional fixing point for connection. By cooperating with the sealing mechanism 3, the firmness of the connection can be increased, preventing loosening or leakage during use. By providing the fixing ring 24, a good seal can be formed at the connection part, preventing fluid from leaking from the connection part during the filtration process and ensuring the filtration effect.

[0031] Specifically, as Figure 3 shown, the sealing mechanism 3 includes an upper cover 31, a clamping plate 32, a connection groove 33, a clamping rod 34, a sealing ring 35, and a water inlet hole 36. The upper cover 31 is clamped on the top of the filter element housing 21.

[0032] Specifically, as Figure 3 shown, the clamping plate 32 is welded to the bottom of the upper cover 31, and the connection groove 33 is opened at the bottom inside the clamping plate 32.

[0033] Specifically, as Figure 3 shown, the clamping rod 34 is slidably connected inside the connection groove 33. The side of the clamping rod 34 close to the connection groove 33 is clamped with the fixing hole 23. The sealing ring 35 is fixedly connected to the inside of the upper cover 31, and the water inlet hole 36 is opened at the top of the upper cover 31.

[0034] In this embodiment: By setting the upper cover 31 clamped to the top of the filter element housing 21, the upper cover 31 can protect the internal structure of the filter element device, prevent dust, impurities, etc. from entering the filter element, and affect the filtration effect. Moreover, the design of the upper cover 31 facilitates the installation and disassembly operations for users, improving the convenience of filter element replacement. By setting the clamping plate 32 welded to the bottom of the upper cover 31, the clamping plate 32 cooperates with the clamping groove 22 on the filter element housing 21, realizing the quick connection between the sealing mechanism 3 and the connecting mechanism 2. The design of the clamping plate 32 makes the connection more firm and not easy to loosen. And the shape and size of the clamping plate 32 match the clamping groove 22, which can ensure the accurate position of the upper cover 31 during installation and guarantee the sealing effect. By setting the connecting groove 33, it provides an installation space for the clamping rod 34. During the connection process, the clamping rod 34 can slide in the connecting groove 33 to realize the clamping with the fixing hole 23, thus completing the connection between the sealing mechanism 3 and the connecting mechanism 2. And the design of the connecting groove 33 can guide the movement direction of the clamping rod 34 to ensure the smooth progress of the clamping process. By setting the clamping rod 34 slidably connected to the inner side of the connecting groove 33, the clamping rod 34 realizes the firm connection between the sealing mechanism 3 and the connecting mechanism 2 through clamping with the fixing hole 23. The design of the clamping rod 34 makes the connection more stable and not easy to fall off. And the sliding design of the clamping rod 34 makes the installation and disassembly process more convenient, and users can easily complete the replacement operation of the filter element. By setting the sealing ring 35 fixedly connected to the inner side of the upper cover 31, the sealing ring 35 can form a good seal at the connection part to prevent fluid leakage. The material of the sealing ring 35 usually has good elasticity and corrosion resistance, and can maintain stable sealing performance under different temperatures and pressures. By setting the water inlet hole 36, it is the inlet for the fluid to enter the filter element device, which can ensure that the fluid evenly enters the filter element interior and improve the filtration efficiency.

[0035] Specifically, as Figure 4 、 Figure 5 shown, a pull ring 4 is welded to the side of the clamping rod 34 away from the connecting groove 33, and anti-slip patterns are engraved on the surface of the pull ring 4.

[0036] Specifically, as Figure 3 、 Figure 4 shown, the bottom of the clamping plate 32 is circular, and an anti-corrosion coating is applied on the surface of the clamping plate 32.

[0037] In this embodiment: By providing the pull ring 4, when the filter element needs to be replaced, the user can easily disengage the clamping rod 34 from the fixing hole 23 by pulling the pull ring 4, thereby quickly opening the sealing mechanism 3 for filter element replacement. By providing anti-slip patterns, the friction between the fingers and the pull ring 4 is increased, making the operation of the pull ring 4 more stable and less prone to slipping. Even when there is moisture or grease on the hand, it can ensure that the user can smoothly pull the pull ring 4, improving the convenience and safety of the operation. By setting the bottom of the clamping plate 32 to be circular, when the clamping plate 32 cooperates with the clamping groove 22 of the filter element housing 21, it can be inserted and rotated more smoothly, improving the installation and disassembly efficiency. The circular design also reduces the friction and wear between the clamping plate 32 and the clamping groove 22, extending the service life of the filter element device. By providing anti-corrosion paint, it can effectively prevent the clamping plate 32 from being corroded when contacting various fluids and corrosive substances in the environment. This not only ensures the strength and stability of the clamping plate 32 but also ensures the tight connection between the sealing mechanism 3 and the connecting mechanism 2, preventing leakage problems caused by corrosion.

[0038] Specifically, as Figure 5 shown, both sides of the upper cover 31 are fixedly connected with handles 5, and anti-slip patterns are engraved on the surface of the handles 5.

[0039] Specifically, as Figure 2 shown, the fixing ring 24 is made of corrosion-resistant rubber material, and a silicone rubber coating is applied on the surface of the fixing ring 24.

[0040] In this embodiment: By providing the handles 5, the user can stably operate the upper cover 31 by holding the handles 5 to engage or disengage it with the filter element housing 21. By providing anti-slip patterns, the friction between the palm and the handles 5 is increased, preventing hand slippage during the operation. Whether in a dry or wet environment, the anti-slip patterns can provide a good grip, improving the safety and reliability of the operation. By setting the fixing ring 24 to be made of corrosion-resistant rubber material, it has good chemical corrosion resistance and can maintain stable performance in various harsh environments. Whether in contact with acidic, alkaline or other corrosive fluids, the corrosion-resistant rubber fixing ring 24 can effectively prevent corrosion and ensure the sealing performance of the connection part. By providing the silicone rubber coating, it has good elasticity and flexibility, can better adapt to the shape change of the connection part, provide a more tight seal. At the same time, the silicone rubber coating also has advantages such as high temperature resistance, low temperature resistance, and aging resistance, and can maintain stable performance under different temperature and environmental conditions, ensuring the long-term reliable operation of the filter element device.

[0041] Working principle: First, the user installs the filter element body 1 in a suitable working position. Then, when filter element replacement is required, the user pulls the pull ring 4. At this time, the pull ring 4 drives the clamping rod 34 to smoothly slide inside the connecting groove 33, causing the clamping rod 34 to disengage from the fixing hole 23. Immediately afterwards, the user holds the handles 5 on both sides of the upper cover 31 and pulls the handles 5 by applying force to drive the upper cover 31 to move, thereby separating the sealing mechanism 3 from the connecting mechanism 2. After that, the user carefully removes the upper cover 31 from the top of the filter element housing 21, and then the old filter element body 1 can be taken out from the filter element housing 21. Next, the user gently places the new filter element body 1 into the filter element housing 21. Finally, the user accurately aligns the clamping plate 32 at the bottom of the upper cover 31 with the clamping groove 22 on the inner top of the filter element housing 21 for clamping operation. During the connection process, the user pushes the clamping rod 34 to slide in the connecting groove 33 to achieve precise clamping with the fixing hole 23, thereby completing the connection between the sealing mechanism 3 and the connecting mechanism 2. The user then clamps and fixes the filter element housing 21 with the replaced filter element to the upper cover 31 again, and then connects the filter element body 1 to the water purifier.

[0042] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
