[0024] See also Figure 1-4 The utility model provides a technical solution: an air filter element that is easy to replace, comprising a shell 1, an annular groove is opened on the inner bottom wall of the shell 1, an annular filter element 4 is clamped on the inner bottom wall of the shell 1 located inside the annular groove, a threaded ring 5 is threadedly installed on the inner wall of the shell 1, the inner wall of the threaded ring 5 contacts the annular filter element 4, and a bearing 6 is fixedly installed on the lower end of the threaded ring 5. The lower end of the inner ring wall of the bearing 6 is fixedly connected with a connecting ring 7, and the lower end of the connecting ring 7 is fixedly connected with multiple groups of fan blades 8. Multiple groups of fan blades 8 are fixedly connected to one side close to the annular filter element 4, and multiple groups of brushes 9 are in contact with the outer wall of the annular filter element 4. An outlet pipe 12 is installed at the lower end of the shell 1 below the middle of the annular filter element 4, and an air inlet pipe 2 is installed on the outer wall of the shell 1.

[0025] In the technical solution of the present invention, the air intake pipe 2 can be used to intake air into the interior of the shell 1. When the gas enters the interior of the shell 1, the annular filter element 4 has smooth air intake at the beginning during use, so that the fan blades 8 may not rotate with the cooperation of a small airflow. After the outer wall of the annular filter element 4 is blocked, the airflow between the outer wall and the annular filter element 4 will increase, and then the fan blades 8 will be driven to rotate with the cooperation of the bearing 6. The fan blades 8 can drive the bristles 9 to clean the annular filter element 4, thereby ensuring that the annular filter element 4 is cleaned, and no other accessories are added to the annular filter element 4, which reduces the waste of material of the annular filter element 4.

[0026] In addition, the filtered gas can be discharged through the gas outlet pipe 12.

[0027] In the technical solution of the present utility model, Figure 2 As shown, the upper end of the threaded ring 5 is fixedly connected to the cover 3, and a handle groove 11 is provided on the upper side of the cover 3. The threaded ring 5 can be used to control the cover 3, and the cover 3 is conveniently installed when the threaded ring 5 is screwed to the inner wall of the shell 1. The lower end of the cover 3 is fixedly connected to the inner fixing ring 10, and the outer ring of the inner fixing ring 10 is in contact with the annular filter screen. The inner fixing ring 10 can be fixed by the cover 3, and the cooperation between the inner fixing ring 10 and the threaded ring 5 can clamp the annular filter element 4.

[0028] In the technical solution of the present utility model, Figure 1 As shown, there is a certain gap between the multiple groups of fan blades 8 and the inner wall and inner bottom wall of the outer shell 1. The certain gap between the fan blades 8 and the inner wall and inner bottom wall of the outer shell 1 facilitates the rotation of the fan blades 8.

[0029] When in use, first ensure the sealing and stability by correctly clamping the annular filter element 4 in the annular groove on the inner bottom wall of the outer shell 1. The threaded ring 5 is installed on the inner wall of the outer shell 1 through threads, and its inner wall is in close contact with the annular filter element 4, further fixing the filter element. The bearing 6, connecting ring 7, and multiple sets of fan blades 8 and bristles 9 fixed at the lower end of the threaded ring 5 are all in a stationary state, waiting to be started. The air inlet pipe 2 and the air outlet pipe 12 are respectively installed on the outer wall and bottom of the outer shell 1 to ensure that the air can enter and discharge smoothly. External air enters the interior of the outer shell 1 through the air inlet pipe 2. The air contacts the annular filter element 4, and the filter screen of the annular filter element 4 begins to filter impurities and particulate matter in the air. The filtered clean air enters the interior of the annular filter element 4. When the outer wall of the annular filter element 4 becomes clogged, the airflow between the housing 1 and the annular filter element 4 increases. This airflow, coupled with the bearing 6, facilitates the rotation of the fan blades 8, which in turn drives the bristles 9. This allows the bristles 9 to clean the annular filter element 4. The rotation of the fan blades 8 accelerates the flow of air through the filter element, improving filtration efficiency. The contact between the bristles 9 and the outer wall of the filter element and the rotational speed of the fan blades 8 are designed to ensure effective cleaning without damaging the filter element. Clean air filtered by the filter element continues to flow within the housing, ultimately exiting through an outlet pipe 12 located below the center of the annular filter element 4. The design of outlet pipe 12 ensures that the filtered air can smoothly exit the housing 1, entering the subsequent air treatment system or being discharged directly into the environment. Over time, the filter element may become clogged or damaged and require replacement. At this point, the threaded ring 5 can be loosened and removed from the housing 1. Because a cap 3 with a handle slot 11 is secured to the upper end of the threaded ring 5, this process can be simplified by operating the handle slot 11. After removing the cover 3, the annular filter element 4 can be easily taken out and replaced. Through the above work process, the easily replaceable air filter element can filter the air efficiently while keeping the filter element clean and easy to replace, thereby improving the overall performance and reliability of the air treatment system. It is not only easy to clean, but also reduces the cost of the annular filter during the cleaning process. There is a certain gap between the fan blades 8 and the outer shell 1. The gap is small in the figure and is inconvenient to show. It is only explained here to facilitate the rotation of the fan blades 8 inside the outer shell 1.
