It may be appreciated that the projection of the first vent hole 25111 on the second cover plate 2513 may partially overlap the second vent hole 25133, or the projection of the first vent hole 25111 on the second cover plate 2513 may not overlap the second vent hole 25133. When the projection of the first vent hole 25111 on the second cover plate 2513 does not overlap with the second vent hole 25133, the projection of the first vent hole 25111 on the second cover plate 2513 may be spaced from the second vent hole 25133, or the projection of the first vent hole 25111 on the second cover plate 2513 may be adjacent to the second vent hole 25133, which is not particularly limited in the present application. In a certain embodiment, the projection of the first vent 25111 onto the second cover 2513 is spaced from the second vent 25133. In this way, the ventilation path can be effectively increased, and the probability of dust, scrap iron and other debris passing through the first ventilation holes 25111, the ventilation channels 2515 and the second ventilation holes 25133 can be effectively reduced while ventilation is enabled.

It is to be understood that the shape of the first ventilation hole 25111 is very large, and the first ventilation hole 25111 may have a triangle shape, a circle shape, a quincuncial shape, etc., which is not particularly limited in the present application. The second ventilation holes 25133 have a plurality of shapes, and the second ventilation holes 25133 may have a triangular shape, a circular shape, a quincuncial shape, or the like.

It can be appreciated that the first ventilation holes 25111 and the second ventilation holes 25133 are in one-to-one correspondence, or the plurality of first ventilation holes 25111 and the one second ventilation hole 25133 are in communication, or the one first ventilation hole 25111 and the plurality of second ventilation holes 25133 are in communication, or the plurality of first ventilation holes 25111 and the plurality of second ventilation holes 25133 are in communication. In one embodiment, the plurality of first vent holes 25111 and the plurality of second vent holes 25133 all communicate through the same vent channel 2515. Thus, the production cost can be lower without affecting the ventilation effect.
