Sponge blades are individually inserted through each frame (20) while each lug is positioned at the end. A flapper, arranged between the lug and frame, is mounted on a slot (14) to connect a front cover (30) and a rear base (10), such that each sponge blade extends outward to form the casing of a fan main body.
