[0007] The internal support frame body structure includes a plurality of groups of transverse connection internal ribs and a plurality of groups of longitudinal connection internal ribs arranged in the filter screen frame body. The transverse connection internal ribs and the longitudinal connection internal ribs are arranged in a cross manner, and a large-spacing filter belt is arranged at the middle section position.

[0008] The described edge locking structure includes a fastening edge seat provided at the end of the upper plug-in body and a fastening body provided in the fastening edge seat, and the fastening body is in a frustum shape.

[0009] The beneficial effects of the present utility model: Through the filter mesh structure of the integrated circular air filter with extraction and plug-in, it can prevent the phenomenon that the connection between the upper connecting block structure and the filter mesh component structure is not firm and loose, and it is not easy for the upper connecting block structure and the filter mesh component structure to break. At the same time, the structural design is simple and reasonable, which can effectively help the staff in production to improve the service life of the product.
