[0032] In existing filtration equipment, filter cartridges typically have standardized lengths, meaning each individual cartridge can only fit a specific size cartridge, resulting in poor versatility. Furthermore, cartridge replacement is complex, requiring precise matching of the cartridge's internal space, increasing maintenance costs and time. Therefore, there is a pressing need in the market for a filter cartridge design that is compatible with multiple cartridge lengths and easy to replace, to improve efficiency and reduce operating costs.

[0033] Therefore, such as Figure 1 and Figure 2 As shown, the adaptive filter element proposed in this utility model includes a core cylinder 100 and an elastic element 200. The core cylinder 100 is strip-shaped. One end of the elastic element 200 is integrally fixedly connected to one end of the core cylinder 100, and the other end extends along the side away from the center of the core cylinder 100. This drives the end of the core cylinder 100 facing the elastic element 200 to float and be installed in the filter cartridge 300, and also drives the end of the core cylinder 100 away from the elastic element 200 to press against and be installed in the filter cartridge 300. By introducing the elastic element 200, such as a compression spring, the core cylinder 100 can automatically adjust its position in filter cartridges 300 of different lengths, ensuring that the filter element can fit tightly in filter cartridges 300 within a certain size range, achieving a good sealing effect. This feature greatly improves the versatility of the filter element, allowing a single model of filter element to be used in a series of filter cartridges 300 with different lengths, reducing the need for users to stock multiple different specifications of filter elements, and reducing the complexity and cost of inventory management. Secondly, because the filter element automatically adapts to the internal space of the filter cartridge 300, the installation process becomes simple and quick, eliminating the need for precise matching of the filter cartridge 300 dimensions or additional adjustments. This not only saves time on filter element replacement but also reduces risks caused by improper installation, such as leakage or decreased filtration efficiency. For maintenance personnel, this means fewer operational errors and higher work efficiency. Furthermore, the continuous pressure provided by the elastic element 200 ensures that the filter element maintains a stable installation state throughout its use, maintaining good sealing performance even under vibration or other external influences. This is crucial for maintaining the efficient operation of the filtration system, affecting the stability and reliability of filtration quality. Simultaneously, the elastic element 200 can compensate for dimensional differences caused by manufacturing tolerances or deformation of the filter cartridge 300, further enhancing the system's adaptability and durability. Overall, this significantly improves the filter's overall performance and user experience, providing users with a more flexible, reliable, and easy-to-maintain solution.

[0034] In some embodiments, there are multiple elastic elements (not shown in the figures), which are spaced apart around the centerline of the core cylinder. The same end of each elastic element is fixed to the core cylinder, and the other ends cooperate to elastically press against the filter cylinder. On the one hand, this leaves space in the middle of the core cylinder, for example, for inserting a filter tube or installing other functional components, such as reinforced threaded connections or guiding sliding elements. On the other hand, the arrangement of multiple elastic elements not only increases the axial elastic pressing force of the core cylinder but also further improves the radial floating property of the core cylinder, making it more adaptable for lateral installation. Optionally, the initial lengths of the multiple elastic elements are all the same (not shown in the figures), suitable for installation against a plane of the filter cylinder. Optionally, the initial lengths of at least one elastic element are all different (not shown in the figures), suitable for installation against a non-planar surface of the filter cylinder, for example, the pressing surface between the filter cylinder and the elastic element is a conical surface, as shown in the reference figure. Figure 1 and Figure 2 The filter cartridge 300 includes a cartridge body 310, a first cover 320 disposed at one end of the cartridge body 310, and a second cover 330 disposed at the other end of the cartridge body 310. In some applications, the end of the core cartridge 100 facing the elastic member 200 is pressed against the inner surface of the second cover 330, and the end of the core cartridge 100 away from the elastic member 200 is pressed against the inner surface of the first cover 320. The second cover 330 has a conical structure. The initial lengths of the multiple elastic members can be set to be the same (not shown in the figure), and the distances between the centerlines of the multiple elastic members and the centerline of the core cartridge are all equal, so that the multiple elastic members can press against a line of the same diameter on the inner circumferential surface of the second cover. Alternatively, the initial lengths of at least one elastic member can be set to be different (not shown in the figure). In this case, the distances between the centerlines of the multiple elastic members and the centerline of the core cartridge are not all equal, so that the multiple elastic members can press against radially different positions on the inner circumferential surface of the second cover.

[0035] Refer to Figure 1 and Figure 2 In some embodiments, there is only one elastic element 200, resulting in a simpler connection structure and easier use. Specifically, the elastic element 200 has a circular ring 210 at one end facing the core cylinder 100. The circular ring 210 extends around the center line of the core cylinder 100 and is integrally fixedly connected to the core cylinder 100, ensuring a stable connection between the elastic element 200 and the core cylinder 100 and preventing loosening or detachment during use. It is easy to understand that the design of the circular ring 210 not only increases the overall stability of the structure but also provides a uniformly distributed pressure point for the elastic element 200, allowing the pressure applied by the elastic element 200 to act more evenly on the core cylinder 100, thereby ensuring stable installation and good sealing of the filter element within the filter cartridge 300. Furthermore, the presence of the circular ring 210 facilitates assembly during manufacturing, improves production efficiency, and simplifies subsequent maintenance. Optionally, the elastic element 200 is a compression spring. This specific choice is based on the mechanical advantages of compression springs. Compression springs have high elasticity and durability, and can maintain a stable spring force output over a long period of time. This is crucial for ensuring the adaptability of the filter element within filter cartridges of different lengths 300. Furthermore, compression springs can withstand large pressure changes without easily deforming, making them ideal for filtration environments requiring frequent replacement or long-term use. In addition, compression springs are cost-effective, easy to procure and manufacture, further reducing the overall cost of the product while providing reliable performance assurance.

[0036] In some manufacturing processes, the end of the compression spring facing the core cylinder 100 is welded to the core cylinder 100. It should be noted that welding is a permanent connection method, ensuring the strength and reliability of the connection between the compression spring and the core cylinder 100, maintaining good working condition even in harsh environments such as high pressure and high temperature. Welding not only enhances the overall stability of the structure but also avoids the risk of failure due to loosening or wear of the connectors. This robust connection method is crucial for maintaining the long-term stable operation of the filter element, especially in industrial applications, where it helps improve system reliability and safety, and reduces maintenance needs and downtime.

[0037] Refer to Figure 1 and Figure 2 In some embodiments of this invention, a connecting block 220 is fixedly connected to the end of the elastic element 200 facing away from the core cylinder 100. The connecting block 220 is used for press-fitting installation with the filter cartridge 300. The connecting block 220 provides a direct contact surface to enhance the contact quality between the elastic element 200 and the bottom of the filter cartridge 300, ensuring effective pressure transmission and a tight fit. For example, the connecting block 220 is a circular ring with both ends being flat. In this way, the position of the filter element within the filter cartridge 300 can be better controlled, avoiding irregular deformation or slippage problems that may be caused by the elastic element 200 directly contacting the bottom wall of the filter cartridge 300. In some manufacturing processes, the connecting block 220 is welded to the elastic element 200. Similar to the fixing method of the core cylinder 100 and the compression spring, this fixing method not only ensures a high-strength connection between the connecting block 220 and the elastic element 200 but also simplifies the manufacturing process and reduces the number of components. It should be noted that welding eliminates the risk of loosening or detachment that may arise from other connection methods, such as threaded connections, ensuring that the filter element remains in the correct installation position under all circumstances. Furthermore, welding also contributes to improving the durability and reliability of the entire device, especially in maintaining stable performance when subjected to vibration or other external forces. This has a positive effect on improving the long-term effectiveness of the filter and reducing maintenance costs.

[0038] Furthermore, refer to Figure 1 and Figure 2In some embodiments of this utility model, a first buffer block 221 is provided between the connecting block 220 and the filter cartridge 300. The hardness of the first buffer block 221 is less than that of the connecting block 220, which can protect the connecting block 220 from damage caused by direct impact or friction, and also reduce wear on the surface of the filter cartridge 300. Due to its lower hardness, the first buffer block 221 can form a certain flexible layer on the contact surface, absorbing some vibration energy, reducing noise, and compensating for minor dimensional deviations, ensuring a tighter and more stable installation. In addition, the soft first buffer block 221 can also improve the sealing effect, prevent leakage, and thus improve the performance and reliability of the entire filtration system. Optionally, the connecting block 220 is made of steel, which facilitates welding and fixing with a compression spring that is also made of steel. The first buffer block 221 is made of aluminum, plastic, rubber, or silicone. In some embodiments, the first buffer block 221 is installed on the connecting block 220, and the core cylinder 100, elastic element 200, connecting block 220, and first buffer block 221 together form an independent component. In other embodiments, the first buffer block is mounted on the second cylinder cover (not shown in the figure), and the core cylinder, elastic element and connecting block together form a separate component.

[0039] Refer to Figure 1 and Figure 2 In some embodiments of this utility model, a guide structure is provided between the connecting block 220 and the filter cartridge 300 to guide the installation of the connecting block 220, thereby guiding the connecting block 220 accurately into the bottom position of the filter cartridge 300, ensuring that the filter element is in the correct working posture each time it is installed. This guiding mechanism greatly simplifies the installation process, allowing for quick installation even in limited space or poor lighting conditions, thus improving work efficiency. More importantly, the guide structure helps avoid filter element misalignment or jamming caused by improper installation, ensuring a tight fit between the filter element and the filter cartridge 300, thereby enhancing the system's sealing and filtration effect. In addition, the guide structure can also play a certain positioning role, ensuring that the filter element maintains a stable working state throughout its service life. For example, the first buffer block 221 is equipped with a guide block 2211, which has a flared structure, and the second cartridge cover 330 is provided with a positioning post that aligns with the center of the flared structure. Another example is that the guide block is installed on the second cartridge cover (not shown in the figure), and the center of the first buffer block is provided with a conical surface that guides and engages with the guide block. This effectively guides the centerline of the installed core cylinder 100 to coincide with the centerline of the filter cartridge 300.

[0040] Refer to Figure 1 and Figure 2In some embodiments of this invention, a second buffer block 110 is connected to the end of the core cylinder 100 facing away from the elastic member 200, and the second buffer block 110 is pressed against the filter cartridge 300. Furthermore, a flexible transition interface is provided between the filter element and the top of the filter cartridge 300, such as the first cap 320, which protects the internal structure of the filter cartridge 300 from direct pressure from rigid components and ensures good sealing performance. It is easily understood that, due to its flexible nature, the second buffer block 110 can be slightly adjusted according to the specific shape of the filter cartridge 300 to compensate for manufacturing tolerances, thereby achieving a tighter fit. In addition, the second buffer block 110 also helps to disperse pressure, reduce local stress concentration, and extend the service life of the filter element and filter cartridge 300. This design optimizes the installation experience of the filter element and improves the overall performance of the filtration system. Optionally, the second buffer block 110 is made of aluminum, plastic, rubber, or silicone.
