In an embodiment of the present invention, as shown in fig. 1, a charging device in an embodiment of the present invention includes a housing, and the housing may be any structure suitable for having an accommodating space inside, and the shape of the housing may be reasonably set according to actual needs, for example, the shape of the housing may be an ellipse, a circle, a polygon, or other irregular shapes. Alternatively, as shown in fig. 1, the housing may be circular in shape.

Wherein the housing has an accommodating space. The accommodating space is used for accommodating various components of the charging device, such as a PCB (printed circuit board) and the like.
