[0031] The following is in conjunction with the appended drawings in the embodiment of the present utility model. Figure 1-4The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.
[0032] Please refer to Figure 1-2 An easily removable air filter comprises an upper housing 1, a lower housing 2 mounted at the bottom of the upper housing 1, and a filter element 3 mounted between the interiors of the upper and lower housings 1 and 2. The bottom of the upper housing 1 is integrally connected to an insert portion that plugs into the interior of the lower housing 2. The upper and lower housings 1 and 2 are fixedly connected by bolts. A stepped groove 4 is defined at the center of the upper housing 1. A filter element cover 5 is mounted within the stepped groove 4. A sealing ring 21 is mounted at the bottom of the filter element cover 5. The provision of the sealing ring 21 improves the sealing effect between the filter element cover 5 and the upper housing 1. The bottom of the filter element cover 5 is located above the filter element 3.
[0033] Reference Figure 2-4 When the filter element cover 5 is in the closed position, the filter element cover 5 is in the closed position, and the filter element cover 5 is in the closed position, and the filter element cover 5 is in the closed position, and the filter element cover 5 is in the closed position, and the filter element cover 5 is in the closed position, and the filter element cover 5 is in the closed position, and the filter element cover 5 is in the closed position, and the filter element cover 5 is in the closed position, and the filter element cover 5 is in the closed position, and the filter element cover 5 is in the closed position, and the filter element cover 5 is in the closed position, and the filter element cover 5 is in the closed position, and the filter element cover 5 is in the closed position, and the filter element cover 5 is in the closed position, and the filter element cover 5 is in the closed position, and the filter element cover 5 is in the closed position, and the filter element cover 5 is in the closed position, and the filter element cover 5 is in the closed position, and the filter element cover 5 is in the closed position, and the filter element cover 5 is in the closed position, and the filter element cover 5 is in the closed position, and the filter element cover 5 is in the closed position, and the filter element cover 5 is in the closed position, and the filter element cover
[0034] Reference Figure 2-4A limiting mechanism is installed on the upper shell 1. Specifically, the limiting mechanism includes a mounting groove 11 provided inside the upper shell 1 and connected to the limiting groove 10. A block 12 is slidably installed inside the mounting groove 11. A slide groove 14 is provided on the inner top wall of the mounting groove 11. A slider 15 is fixedly installed at the bottom of the block 12. The slider 15 is slidably installed inside the slide groove 14. The arrangement of the slide groove 14 and the slider 15 enables the block 12 to slide inside the mounting groove 11 while limiting the position of the block 12, so that the block 12 will not be moved out of the mounting groove 11. A spring 13 is fixedly installed between one end of the block 12 and the inner wall of the mounting groove 11. The arrangement of the spring 13 is such that when the connecting rod 8 rotates to the end closed at the top of the limiting groove 10, the block 12 limits the position of the connecting rod 8 under the action of the spring 13, so that the connecting rod 8 will not rotate on its own. One end of the clamping block 12 is designed as a bevel mechanism. This structural arrangement allows the end of the connecting rod 8 to easily pass through the clamping block 12 and enter the interior of the closed end of the top of the limiting groove 10 when the connecting rod 8 is rotated. A moving block 16 is fixedly mounted on the top of the clamping block 12. A through groove 17 communicating with the mounting groove 11 is formed on the upper surface of the upper shell 1. The moving block 16 extends through the interior of the through groove 17. The arrangement of the moving block 16 can easily move the clamping block 12, causing the clamping block 12 to retract into the mounting groove 11, thereby releasing the limit on the connecting rod 8.
[0035] Reference Figure 1 A mounting seat 18 is fixedly installed on the inner top wall of the lower shell 2, and the bottom of the filter element 3 is inserted into the mounting seat 18. The top of the filter element 3 is located inside the stepped groove 4, and a movable plate 19 is slidably installed inside the mounting seat 18. A lifting spring 20 is fixedly installed between the bottom of the movable plate 19 and the inner bottom wall of the mounting seat 18. Through the setting of the lifting spring 20, when the filter element cover 5 is moved out from the inside of the stepped groove 4, the filter element 3 bounces upward under the elastic action of the lifting spring 20, thereby facilitating the removal of the filter element 3 from the inside of the device for replacement.
[0036] The implementation principle of the present utility model is as follows: when in use, the bottom of the filter element 3 is installed inside the mounting seat 18, and then the filter element cover 5 is placed inside the stepped groove 4, and the rotating shaft 7 is rotated by the knob 9, thereby driving the connecting rod 8 to rotate. Since one end of the clamping block 12 is designed as an inclined mechanism, when the connecting rod 8 is rotated, the end of the connecting rod 8 can more easily pass through the clamping block 12 and enter the interior of the closed end of the top of the limiting groove 10. When the connecting rod 8 rotates to the closed end of the top of the limiting groove 10, the top of the limiting groove 10 limits the connecting rod 8, so that the filter element cover 5 is not easy to fall off from the inside of the stepped groove 4, thereby achieving the preliminary installation of the filter element cover 5. At the same time, under the action of the spring 13, the clamping block 12 limits the position of the connecting rod 8, so that the connecting rod 8 will not rotate on its own, thereby achieving stable installation of the filter element cover 5, wherein a sealing ring 21 is installed at the bottom of the filter element cover 5, and the sealing ring 21 is located in the stepped groove 4, which improves the sealing effect between the filter element cover 5 and the upper shell 1;
[0037] When the filter element 3 needs to be replaced, the block 12 is moved by the moving block 16, and the block 12 is retracted into the installation groove 11, thereby releasing the limit on the connecting rod 8, and the knob 9 is rotated in the opposite direction to make the connecting rod 8 rotate to the open end at the top of the limiting groove 10, and the filter element cover 5 can be taken out from the inside of the stepped groove 4. Then, the filter element 3 bounces upward under the elastic action of the lifting spring 20, so that the filter element 3 can be easily taken out from the inside of the device for replacement.
[0038] To sum up, through the coordinated arrangement of the locking mechanism and the limiting mechanism, the filter element cover 5 can be quickly disassembled and assembled, and under the limiting action of the limiting mechanism, the locking mechanism in the filter element cover 5 can stably achieve connection with the upper shell 1, ensuring the stability of the filter element 3 installed inside the device. At the same time, the filter element 3 can be quickly disassembled and replaced, thereby effectively solving the problem that the existing air filter may become loose due to vibration during high-speed driving of the vehicle.
[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
