Abstract

The utility model relates to a case panel of an electronic device, in particular to a ventilation shielding dustproof panel with favorable ventilation, shielding and dustproof effects; the panel is provided with an air vent; the air vent on the panel is provided with a cutoff waveguide plate; the cutoff waveguide plate is covered with a dust shield; and a dustproof pad is arranged between the dustproof shield and the cutoff waveguide plate. The panel which is integrated into a whole by the cutoff waveguide plate with regular hexagon has the advantages of large ventilation area, good electromagnetic leakage resistance performance and beautiful exterior. The air vents of the dust shield and the cutoff waveguide plate have same or corresponding hole shapes, thus reducing the increased wind resistance caused by different or non-corresponding hole shapes; a through hole sponge or a wire mesh dustproof pad arranged between the dustproof shield and the cutoff waveguide plate can be taken out and washed at any time; and the case panel is applicable to various severe environments.
