In the present embodiment, the supporting frame 1111 is completely covered with the covering layer 1112 to form a hollow sealing structure in which the supporting frame 1111 is a skeleton and the covering layer 1112 is an outer surface. In this embodiment, the coating 1112 is made of a water-repellent super-hydrophobic material.
