The bottom of the mounting portion 642 is located in the second receiving groove 218 and is provided with a boss 6421 that protrudes into the first connection hole 222. Preferably, the cross-sectional outer contour of the mounting portion 642 is generally arc-shaped and matches the inner contour of a portion of the second side wall 2e, thereby acting as a limiter. The lens assembly 63 includes a threaded sleeve 631 housed in a cylindrical body 641 , a retainer 632 housed in the threaded sleeve 631 , and a lens 633 mounted in the retainer 632 . The inner wall of the cylindrical body 641 is provided with threads threadedly connected to the threaded sleeve 631 .

[0050] When the projection night light begins operating, the control board 9 controls the motor 51 to rotate the projection disk 62 and illuminate the second lamp bead 612. As the projection disk 62 continues to rotate, the multiple pattern printed portions 6231 on the projection light sheet 623 are aligned vertically with the lens assembly 63. Light from the second lamp bead 612 passes through the pattern printed portions 6231 and the lens assembly 63, creating a projection effect of a passing meteor. The projection effect created by the projection light sheet 623 serves as the background for the projected meteor. That is, the projection light sheet 623 projects a dynamic effect of a pattern sliding by. Combined with the background effect created by the imaging sheet 335, this dynamic sliding projection effect is more vivid and aesthetically pleasing than the circumferential rotation effect of traditional projection.

[0051] In summary, the projection night light of the present invention has the following beneficial effects:

[0052] (1) The projection component includes a first light board, a first lamp bead located above the first light board, a first light guide, an imaging disk, and a projection lens; the pattern disk assembly includes a second light board, a second lamp bead located above the second light board, a second light guide, a projection disk, and a lens group. The projection formed by the projection component constitutes a main projection, and the pattern disk assembly forms an auxiliary projection. The main projection and the auxiliary projection cooperate with each other to form a rich projection effect to meet user needs.

[0053] The above describes in detail the projection night light provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above examples is intended only to help understand the core concept of the present invention. It should be noted that those skilled in the art may make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
