[0026] Please refer to Figure 1 and Figure 2 As shown, it shows the specific structure of a preferred embodiment of the utility model, including a cylindrical filter material 10, a bottom cover 20 and a top cover 30.

[0027] The cylindrical filter material 10 has an airflow channel 101 extending up and down, and the cylindrical filter material 10 includes an inner layer 11 and an outer layer 12. The inner layer 11 is formed to form the airflow channel 101, and the inner layer 11 is a mesh-covered carbon cloth, and its main function is to utilize the adsorption capacity of the carbon cloth to deodorize and remove odors. The mesh on the carbon cloth increases the strength of the cylindrical filter material 10 and makes the cylindrical filter material 10 more upright. The outer layer 12 is coated on the outside of the inner layer 11, and the outer layer 12 is a polyester oil-proof and waterproof filter paper, and its main function is to filter out oil, water and solid particles in the air. In the present embodiment, the outer layer 12 is made of polyester long fiber material, and the outer layer 12 is pleated, which increases the filtration area of ​​the cylindrical filter material 10 and improves the air volume of the filter element. In addition, the outer layer 12 is provided with a plurality of straps 13 on the outside, and the plurality of straps 13 are arranged at intervals up and down to increase the strength of the filter element and evenly distribute the filter paper.
