Since the night light body and the charging base structure are separate, only the conversion is completed in the charging base structure, and then the two magnets cooperate to be powered on to achieve an efficient rectification and step-down function, reducing energy loss.

[0039] At the same time, during actual application, a convex ring 5 is provided outside the through hole of the charging base structure or the night light body. A second guide electromagnet structure 3 is provided in the through hole of the night light body. The charging base structure and the night light body are rotatably magnetically connected through the first guide electromagnet structure and the second guide electromagnet structure. At the same time, the sizes and shapes of the first guide electromagnet structure and the second guide electromagnet structure are matched. At the same time, the night light body can be rotated at any angle on the charging base structure to meet the usage requirements in different situations.

[0040] In this embodiment, through holes can be provided on the night light body, and convex rings can be provided at the through holes of the charging base structure.
