[0008] Furthermore, the included angles between the two flanges of the common rib of two adjacent air outlets and the inner side surface of the cover plate are equal.

[0009] Furthermore, the widths of the two flanges of the common ribs of two adjacent air outlets are equal.

[0010] Under this technical solution, the two flanges of the common rib of two adjacent air outlets are symmetrically arranged, and the structural strength of the rib on both sides along the extension direction is more balanced, more regular and more beautiful.

[0011] Furthermore, a first rib is formed between two adjacent rows of the air outlets along a first direction, and a plurality of the first ribs are arranged at intervals along the first direction; a second rib is formed between two adjacent rows of the air outlets along a second direction, the second direction intersects with the first direction, and a plurality of the second ribs are arranged at intervals along the second direction.

[0017] Under this technical solution, the central connecting portion and the outer ring connecting portion play the role of connecting the first radial ribs and supporting the first radial ribs and the annular ribs.

[0018] Furthermore, the radial ribs also include second radial ribs, one end of the second radial ribs is connected to a circle of the annular ribs, and the other end of the second radial ribs is connected to the outer ring connecting portion.

[0019] Under this technical solution, as the radius gradually increases, the farther away from the central connection part and the closer to the outer ring connection part, the greater the distance between two adjacent first radial ribs. Therefore, providing the second radial ribs can strengthen the connecting and supporting effect of the radial ribs on the annular ribs, thereby making the structural strength of the entire mesh cover better and more stable.

[0020] Furthermore, the annular ribs are evenly arranged in the radial direction, and the first radial ribs and the second radial ribs are alternately and evenly arranged in the circumferential direction.
