A housing is fixedly connected to the inner wall of the fixing ring. A fixing block is slidably connected to the upper inner wall of the housing. A sliding groove is provided inside the fixing block, and a fixing post is slidably connected to the inner wall of the sliding groove. A rotating rod is fixedly connected to the outer wall of the fixing post and rotatably connected to the outer wall of the housing. A spring is fixedly connected to the bottom end of the fixing block, and the bottom end of the spring is fixedly connected to the lower inner wall of the housing. A fixing component is provided on the upper surface of the fixing block for fixing the first base.

[0007] Preferably, the fixing component includes a connecting rod, the bottom end of which is fixedly connected to the upper surface of the fixing block, and a soft ball is fixedly connected to the upper outer wall of the connecting rod.

[0008] Preferably, the outer wall of the soft ball is slidably connected to the inner wall of the outer shell, and the outer wall of the soft ball is disposed on the inner wall of the slot.

[0009] Preferably, the bottom end of the fixing ring is fixedly connected to the filter core body.

[0010] Preferably, the filter element body has filter holes inside.

[0011] Preferably, a metal inner lining mesh is fixedly connected to the inner wall of the filter element body.

[0012] Preferably, a second base is fixedly connected to the bottom end of the filter element body.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the connecting rod drives the fixed block to slide, and the sliding of the fixed block drives the spring to compress, thereby facilitating the all-round cleaning of each component, ensuring the cleanliness of the filter element, maintaining its good filtration performance, and at the same time, after disassembly, the dust in its pleated parts can be thoroughly removed.

[0015] 2. In this utility model, by opening filter holes in the filter screen body, impurities are evenly distributed on the filter element, so that the filtration load of each part of the filter element is relatively balanced, avoiding excessive wear in some areas. Each radial area is consumed at a reasonable rate according to its filtration capacity and the characteristics of intercepting impurities, thereby extending the service life of the entire filter element.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1-3 An embodiment of this utility model provides: a circular filter core that is easy to clean, including a first base 1, a slot 2 is provided inside the first base 1, a fixing ring 3 is provided at the bottom end of the slot 2, a shell 4 is fixedly connected to the inner wall of the fixing ring 3, a fixing block 5 is slidably connected to the upper inner wall of the shell 4, a sliding groove 6 is provided inside the fixing block 5, a fixing post 7 is slidably connected to the inner wall of the sliding groove 6, a rotating rod 8 is fixedly connected to the outer wall of the fixing post 7, the rotating rod 8 is rotatably connected to the outer wall of the shell 4, a spring 9 is fixedly connected to the bottom end of the fixing block 5, the bottom end of the spring 9 is fixedly connected to the lower inner wall of the shell 4, and a fixing component is provided on the upper surface of the fixing block 5, the fixing component is used to fix the first base 1;

[0024] Specifically, the fixing ring 3 is used to support the first base 1 and the outer shell 4, and at the same time to provide primary protection for the filter element body 12, while the first base 1 provides secondary protection for the filter element body 12, and the fixing block 5 is used to drive the spring 9 to compress.

[0025] Reference Figures 2-3 The fixing component includes a connecting rod 10, the bottom end of which is fixedly connected to the upper surface of the fixing block 5, and a soft ball 11 is fixedly connected to the upper outer wall of the connecting rod 10; the outer wall of the soft ball 11 is slidably connected to the inner wall of the outer shell 4, and the outer wall of the soft ball 11 is set on the inner wall of the slot 2.

[0026] Specifically, the connecting rod 10 is used to fix the soft ball 11, the outer shell 4 is used to support the connecting rod 10 to slide on the inner wall, and at the same time prevent the connecting rod 10 from shifting position during use, and the soft ball 11 is used to fix the first base 1.

[0027] Reference Figure 4 The bottom end of the fixing ring 3 is fixedly connected to the filter core body 12; the filter core body 12 has a filter hole 13 inside; the inner wall of the filter core body 12 is fixedly connected to a metal inner mesh 14; the bottom end of the filter core body 12 is fixedly connected to a second base 15.

[0028] Specifically, the filter element body 12 is used to filter air, the metal inner mesh 14 is used to support the filter element body 12 and enhance the outer wall structure of the filter element body 12, and the filter holes 13 are arranged in descending order of size, which can make impurities evenly distributed inside the filter element body 12.

[0029] Working principle: When the device is needed, pressing the first base 1 causes it to slide downwards, which in turn causes the slot 2 to press against the connecting rod 10. As the connecting rod 10 moves, the fixing block 5 slides against the inner wall of the outer casing 4. This sliding motion of the fixing block 5 compresses the spring 9, causing the fixing post 7 to slide against the upper inner wall of the sliding groove 6. During this sliding process, the fixing post 7 causes the rotating rod 8 to rotate against the lower outer wall of the outer casing 4. Finally, the first base 1 is pulled out, causing the soft ball 11 to disengage from the inner wall of the slot 2. This allows for convenient and comprehensive cleaning of each component, ensuring the cleanliness of the filter element and maintaining its good filtration performance. Disassembly also allows for thorough removal of dust from the pleated areas. This is achieved by opening a groove on the inner wall of the filter element body 12. The filter holes 13 are arranged in a radially gradient pattern, ensuring a uniform distribution of impurities across the filter element. This results in a relatively balanced filtration load across all parts of the filter element, preventing excessive wear in certain areas. Each radial region is consumed at a reasonable rate based on its filtration capacity and impurity interception characteristics, thus extending the overall lifespan of the filter element. This easy-to-clean circular filter element not only allows for comprehensive cleaning of each component, ensuring the cleanliness of the filter element and maintaining its good filtration performance, but also allows for thorough removal of dust from the pleats after disassembly. Furthermore, the uniform distribution of impurities across the filter element ensures a relatively balanced filtration load across all parts, preventing excessive wear in certain areas. Each radial region is consumed at a reasonable rate based on its filtration capacity and impurity interception characteristics, thus extending the overall lifespan of the filter element.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
