[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] like Figures 1-3 As shown, a multifunctional starry sky projection lamp includes a housing 1, a projection device 2, a main control PCB board 3, and a speaker 4. The projection device 2, the main control PCB board 3, and the speaker 4 are installed inside the housing 1, and the main control PCB board 3 is electrically connected to the projection device 2 and the speaker 4 respectively.

[0027] like Figure 4As shown, the projection device 2 includes a main support 21, which has a first mounting slot 21a, a second mounting slot 21b, and a third mounting slot 21c. A cloud projection mechanism 22 is installed in the first mounting slot 21a, which projects a cloud-shaped light pattern. A moon projection mechanism 23 is installed in the second mounting slot 21b, which projects a moon-shaped light pattern. A star projection mechanism 24 is installed in the third mounting slot 21c, which projects a star-shaped light pattern. In addition, the main control PCB board 3 has a storage module that stores white noise audio, which is played through a speaker.

[0028] like Figure 5 As shown, the cloud projection mechanism 22 includes a motor 221, a cloud mirror 222, a first lamp plate 223, a lamp cup bracket 224, and a lamp cup 225. The output shaft of the motor 221 is connected to the cloud mirror 222. The surface of the cloud mirror 222 is provided with concave and convex textures. The first lamp plate 223 is installed below the main bracket 21. The lamp cup bracket 224 is installed on the first lamp plate 223. The lamp cup bracket 224 is bowl-shaped. The lamp cup 225 is installed above the lamp cup bracket 224. The cloud mirror 222 is located above the lamp cup 225 and partially covers the lamp cup 225. The motor 221 causes the cloud mirror 222 to rotate. The cloud mirror 222 is a transparent disc. The light emitted by the first lamp plate 223 is projected through the lamp cup 225 and the cloud mirror 222 to form the visual effect of rotating clouds. The cloud projection mechanism 22 also includes a hemispherical mirror 226, which extends from the top of the housing and is aligned with the cloud mirror 222. The gradually changing glow effect is achieved through the four-color LEDs of the built-in first light panel 223. By adjusting the brightness and mixing ratio of each color, various color-changing effects can be created. The motor reduction assembly drives the rotating cloud mirror 222 of uneven thickness. The LED light passes through this cloud mirror 222 and the refracting lens of the hemispherical mirror 226 on the top of the body, and finally shines on the surface of the object to form a dynamic glow effect.

[0029] like Figure 6 As shown, the moon projection mechanism 23 includes a second light panel 231, a lens bracket 232, a condenser lens 233, a moon plate fixing cover 234, a moon film 235, and an aspherical lens 236. The second light panel 231 is installed below the main bracket 21, and the lens bracket 232 is installed in the main bracket 21. The lens bracket 232 is located above the second light panel 231. The condenser lens 233, the moon plate fixing cover 234, and the aspherical lens 236 are installed sequentially from bottom to top inside the lens bracket 232. The moon film 235 is installed inside the moon plate fixing cover 234. The light emitted by the second light panel 231 is projected onto the moon film 235 to form a moon light image.

[0030] like Figure 7As shown, the star projection mechanism 24 includes a laser support 241, a heat sink aluminum base 242, a laser module 243, and a grating lens 244. The laser support 241 is installed below the main support 21, and the heat sink aluminum base 424 is installed on the laser support 241. The laser module 243 is installed inside the heat sink aluminum base 242, and the grating lens 244 is installed on the upper end of the laser module 243. The laser emitted by the laser module 243 is shaped into a star pattern by the grating lens 244. Specifically, the green laser beam emitted by the laser module 243 hits the grating lens 244. The grating lens 244 is a special optical element with a tiny structure on its surface that can scatter light, causing it to propagate in multiple directions. These scattered light beams hit the object, forming light spots. By controlling the power supply of the laser to repeatedly and slowly increase and decrease its luminous intensity, a flickering effect can be achieved.

[0031] Specifically, the white noise audio includes wind sounds, insect chirps, campfire sounds, thunderstorm sounds, ocean wave sounds, stream sounds, birdsong sounds, and noise effects. Multiple function buttons 5 are installed on the top of the casing 1, which can control the volume, timer, and other settings of different white noise audio. Additionally, the main control PCB board 3 has a Bluetooth transmission module. The mobile device transmits external music signals to the main control PCB board via Bluetooth, and the main control PCB board controls the speaker to play music, allowing users to play their favorite music via their mobile phones.

[0032] Specifically, a display device 6 is installed on the front of the housing 1. The display device 6 is mainly a screen that displays icons such as time, alarm clock, day of the week, Bluetooth, countdown timer, power on / off, etc., providing users with a better user experience.

[0033] Specifically, the housing 1 includes a bottom shell 11, an upper shell 12, a front shell 13, and a rear shell 14. The bottom shell 11, upper shell 12, front shell 13, and rear shell 14 can be interlocked to form the housing 1. The bottom shell 11, upper shell 12, front shell 13, and rear shell 14 surround each other to form an installation space. The main control PCB board 3, the projection device 4, and the speaker 4 are located in the installation space, and part of the projection device 4 is exposed from the upper shell 12.

[0034] The above description is a further detailed explanation of the present utility model in conjunction with specific preferred embodiments. It should not be considered that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the protection scope of the present utility model.
