The first light source 621, the first lens group 622, the insert assembly 623, and the second lens group 624 may be arranged along the optical axis Z1. Light emitted from the first light source 621 can be transmitted along the optical axis Z1 and can sequentially pass through the first light source 621, the first lens group 622, the insert assembly 623, and the second lens group 624 to present a pattern corresponding to the insert assembly 623. In some embodiments, the light-shielding tube 611, the socket 612, and the light-shielding cover 613 may be arranged along the optical axis Z1. In some embodiments, the axial direction of the light-shielding tube 611 coincides with the optical axis Z1.

[0054] The first light source 621 can be connected to the motherboard 20 to emit light under the control of the motherboard 20. Its emission is also influenced by the operation of the control panel 30 and even the battery 50.

The drive mechanism 63 can drive the rotating plate 626 to rotate, which in turn causes the sheet 627 to rotate as well. This causes the pattern projected by the first projection assembly 60 to rotate as well, creating a special atmosphere. In some embodiments, the sheet 627 may be a film. In some embodiments, the sheet 627 is used to generate images such as planets, galaxies, starry skies, etc., and other sheets 627 may be selected as needed.

[0061] In some embodiments, the sidewall of the groove 6251 is provided with a notch 6252 to extend to the edge of the insert plate 625, so that the rotating plate 626 is exposed at the notch 6252 and cooperates with the drive mechanism 63.

[0062] The rotating plate 626 can be placed within the groove 6251, and can rotate about a pivot within the groove 6251. Furthermore, to realize the rotation function of the rotating plate 626, the rotating plate 626 can also be rotatably connected to the insert plate 625. In some embodiments, when the rotating plate 626 and the insert plate 625 are rotatably connected, the groove 6251 can be omitted.

[0063] In some embodiments, the rotating plate 626 may be provided with teeth to engage with the drive mechanism 63 via tooth meshing.

[0064] In some embodiments, the rotating plate 626 may include a support plate 6261 that carries the sheet 627 and a clamping plate 6262 that presses the sheet 627 onto the support plate 6261. The support plate 6261 may be detachably connected to the clamping plate 6262 to clamp the sheet 627. This allows the rotating plate 626 and / or the sheet 627 to be replaced at any time. Of course, the support plate 6261 may also be connected to the clamping plate 6262 in other ways, thereby allowing the rotating plate 626 to be replaced at any time.

[0065] In some embodiments, the second lens group 624 may be installed inside the light shield 613.

[0067] The drive mechanism 63 may include a drive body 631 and a drive shaft 632 that is driveably connected to the drive body 631. In some embodiments, a first conical wheel 6321 is provided on the drive shaft 632 for changing the transmission direction. In some embodiments, the drive body 631 may be a motor or other type of electrically powered drive source, which will not be described in detail. In some embodiments, the drive mechanism 63, such as the drive body 631, may be connected to the motherboard 20 to drive under the control of the motherboard 20, and may also be driven by the operation of the control panel 30, and even by the battery 50. In some embodiments, the main shaft of the drive body 631 is driveably connected to the drive shaft 632. In some embodiments, the axial direction of the main shaft of the drive body 631 is parallel to the axial direction of the drive shaft 632. In some embodiments, the axial direction of the drive shaft 632 intersects the axial direction of the rotating shaft corresponding to the rotating plate 626. In some embodiments, the included angle between the axial direction of the drive shaft 632 and the axial direction of the rotating shaft corresponding to the rotating plate 626 is an acute angle or an obtuse angle.
