[0021] Please see Figures 1-5An air filter element includes an air filter assembly 1, a quick-installation mechanism, a fixed and detachable mechanism, and a stabilizing mechanism. The quick-installation mechanism includes an installation sleeve 2 and a bottom ring 3. The bottom ring 3 is installed at the bottom end of the air filter assembly 1 and can be embedded in the installation sleeve 2. The installation sleeve 2 is equipped with a locking sleeve 4. A locking rod 5 is slidably installed on the bottom ring 3 and can extend into the locking tube. The fixed and detachable mechanism includes a rotating plate 6 and a moving ring 7. The rotating plate 6 is rotatably installed on the side wall of the locking tube, and the moving ring 7 is longitudinally moved on the outer wall of the locking tube. A slot 8 is formed on the outer wall of the locking rod 5. A locking block 9 is installed at one end of the rotating plate 6. The moving ring 7 can press against the rotating plate 6, causing the locking block 9 to extend into the slot 8 and fix the locking rod 5 in the locking sleeve 4. The locking block 9 and the slot 8 are rounded. The locking rod 5 can be pulled forcefully to move the locking block 9 away from the slot 8.

[0022] In this embodiment, the bottom ring 3 of the air filter assembly 1 is directly embedded into the mounting sleeve 2 for initial positioning. The locking rod 5 slides laterally into the locking sleeve 4 along the groove 15 on the inner wall of the bottom ring 3, completing the quick insertion installation. The entire installation process does not require complicated operations; it only requires aligning and inserting the locking rod 5, which significantly improves installation efficiency. After the locking rod 5 extends into the locking sleeve 4, the rotating ring 7 is rotated to move it vertically downward, pressing against the rotating plate 6 and driving it to rotate. This causes the locking block 9 to be embedded into the slot 8 on the outer wall of the locking rod 5, firmly locking the locking rod 5 in the locking sleeve 4, thus achieving reliable fixation of the air filter assembly 1. When disassembly is required, the rotating ring 7 is rotated in the opposite direction to move it upward, the rotating plate 6 is reset, and the locking block 9 exits the slot 8. Since both the locking block 9 and the slot 8 are designed with rounded corners, the locking block 9 can smoothly slide out of the slot 8 when the locking rod 5 is pulled forcefully, achieving quick disassembly.

[0023] The stabilizing mechanism includes a rotating frame 10 and a rotating ring 11. The rotating ring 11 is rotatably mounted on the outer wall of the locking sleeve 4. The rotating ring 11 is mounted on the top end of the rotating frame 10. A fixing block 201 is fixedly mounted on the outer wall of the locking sleeve 4. A positioning spring 12 is mounted on the fixing block 201. The positioning spring 12 can be embedded in the rotating ring 11 to stabilize the rotation of the outer frame. The rotating ring 11 is threadedly connected to the moving ring 7.

[0024] In this embodiment, the rotating frame 10 is installed on the top of the rotating ring 11 and threadedly connected to the moving ring 7. When the rotating frame 10 is rotated, the rotating ring 11 rotates synchronously. The positioning spring 12 of the fixing block 201 on the outer wall of the locking sleeve 4 is embedded into the positioning groove 18 of the rotating ring 11 in stages, providing staged positioning and rotational feel feedback, ensuring that the rotating frame 10 rotates stably and the moving ring 7 moves precisely longitudinally, effectively preventing slippage or loosening during rotation.

[0025] Please see Figures 1-5As a supplementary embodiment of the air filter element to the quick-installation mechanism, fixed detachable mechanism and stabilizing mechanism: an external plate 13 is installed at the bottom end of the side wall of the mounting sleeve 2, and the external plate 13 is fixedly connected to the external equipment. A mounting platform 14 is provided on the side wall of the mounting sleeve 2, and the locking sleeve 4 is fixedly installed on the mounting platform 14. An inner wall groove 15 is opened on the inner wall of the bottom ring 3, and the locking rod 5 can slide in the inner wall groove 15. A limiting block 16 is installed at one end of the locking rod 5, and the locking rod 5 can pass through the bottom ring 3 and the mounting sleeve 2 to engage with the locking sleeve 4. A connecting plate 17 is installed at one end of the side wall of the locking sleeve 4, and the connecting plate 17 is fixedly installed on the mounting platform 14. A positioning groove 18 is opened on the rotating ring 11, and the positioning spring 12 is embedded in the positioning groove 18 in stages to make the rotating ring 11 and the rotating frame 10 rotate stably.

[0026] More specifically, during installation, the bottom ring 3 of the air filter assembly 1 is aligned and embedded into the mounting sleeve 2. The locking rod 5 slides laterally into the locking sleeve 4 along the inner wall groove 15. The rotating frame 10 is rotated, and the positioning spring 12 is embedded into the positioning groove 18 of the rotating ring 11 step by step to provide stable rotation. The moving ring 7 moves down and presses against the rotating plate 6. The locking block 9 is embedded into the slot 8 to lock the locking rod 5, thus completing the quick installation and firm fixation of the air filter assembly 1. During disassembly, the rotating frame 10 is rotated in the opposite direction to move the moving ring 7 up to release the locking. The locking rod 5 is pulled forcefully, and the rounded corner locking block 9 smoothly exits the rounded corner slot 8, allowing the air filter assembly 1 to be quickly removed. The entire device realizes the quick installation, reliable fixation, and convenient disassembly of the air filter element, significantly improving the efficiency of replacement and maintenance.

[0027] In summary, when the entire device is in use or running: when the quick installation mechanism is required, the bottom ring 3 at the bottom of the air filter assembly 1 is directly embedded into the mounting sleeve 2 to achieve initial positioning. The locking rod 5 slides laterally along the groove 15 on the inner wall of the bottom ring 3 and extends into the locking sleeve 4 to complete the quick insertion installation. The entire installation process does not require complicated operations; it only requires aligning and inserting the locking rod 5, which significantly improves installation efficiency.

[0028] When the detachable mechanism needs to be fixed, after the locking rod 5 extends into the locking sleeve 4, the rotating moving ring 7 is rotated to move it vertically downward, pressing against the inserting plate 6 and driving it to rotate. This causes the locking block 9 to embed into the slot 8 on the outer wall of the locking rod 5, firmly locking the locking rod 5 in the locking sleeve 4, thus achieving reliable fixation of the air filter assembly 1. When disassembly is required, the moving ring 7 is rotated in the opposite direction to move it upward, the inserting plate 6 is reset, and the locking block 9 exits the slot 8. Since both the locking block 9 and the slot 8 are designed with rounded corners, the locking block 9 can smoothly slide out of the slot 8 when the locking rod 5 is pulled forcefully, achieving quick disassembly.

[0029] When the mechanism needs to be stable, the rotating frame 10 is installed on top of the rotating ring 11 and threadedly connected to the moving ring 7. When the rotating frame 10 is rotated, the rotating ring 11 rotates synchronously. The positioning spring 12 of the fixing block 201 on the outer wall of the locking sleeve 4 is embedded in the positioning groove 18 of the rotating ring 11 in stages, providing staged positioning and rotational feel feedback, ensuring that the rotating frame 10 rotates stably, and the moving ring 7 moves precisely longitudinally, effectively preventing slippage or loosening during rotation.

[0030] During installation, align the bottom ring 3 of the air filter assembly 1 with and insert it into the mounting sleeve 2. The locking rod 5 slides laterally into the locking sleeve 4 along the inner wall groove 15. Rotate the rotating frame 10, and the positioning spring 12 is inserted into the positioning groove 18 of the rotating ring 11 step by step to provide stable rotation. The moving ring 7 moves down and presses against the rotating plate 6. The locking block 9 is inserted into the slot 8 to lock the locking rod 5, thus completing the quick installation and firm fixation of the air filter assembly 1. During disassembly, rotate the rotating frame 10 in the opposite direction to move the moving ring 7 up to release the locking. Pull the locking rod 5 forcefully, and the rounded corner locking block 9 smoothly exits the rounded corner slot 8, allowing the air filter assembly 1 to be quickly removed. The entire device realizes the quick installation, reliable fixation, and convenient disassembly of the air filter element, significantly improving the efficiency of replacement and maintenance.
