In this embodiment, the opening of the hollow cavity 210 of the lower case 200 is disposed toward a side away from the upper case 100, the opening of the receiving groove 421 of the second mounting seat 420 is toward the same direction as the opening of the hollow cavity 210, the fan further includes a cover plate 300 fixedly connected to the lower case 200, the cover plate 300 may be, but not limited to, connected to the lower case 200 by screws, and the cover plate 300 covers both the opening of the hollow cavity 210 and the opening of the receiving groove 421, so as to protect the battery 920 in the receiving groove 421 from moisture erosion and prevent the stand 400 from coming out of the hollow cavity 210.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
