[0036] The working principle of this utility model will be further explained below.

[0037] During assembly, firstly, based on the dimensions of the projection component 200 and the control component 300, select a matching top cover 110 and base 120 to ensure that the projection component 200 and the control component 300 can be fixed inside the housing 100; firstly, install the turntable 220 with the light-emitting device 210 inside the bracket 230, and then install the turntable 220 and the connecting ring 250 on the bracket 230 in sequence; next, fix the first button 310, the ring 330, the speaker 260, the second button 320, and the drive device 231 inside the base 120, and fix the bracket 230 on the ring 330. On ring 330, gear 233 meshes with thread 221, and contact part 253 is aligned with the first button 310. Then, the protrusions 243 of light-diffusing part 242 and light-transmitting part 240 are inserted into fixing ring 222 and fixedly connected to turntable 220. The pattern 241 on light-transmitting part 240 can be selected in different shapes, such as animals, regular geometric patterns, etc. Next, the upper cover 110 is quickly and stably fixed to connecting ring 250 by inserting the clip 111 into the slot 252, completing the installation of upper cover 110. Finally, cover plate 123 is installed on the outside of battery compartment 122. This completes the assembly process of the rotating projection device. The whole process is efficient and controllable, and upper cover 110, light-transmitting part 240, light-diffusing part 242 and light-emitting device 2100 can be quickly and stably positioned and installed.

[0038] During use, the battery is installed in the battery compartment 122. Then, the top cover 110 is pressed down. The top cover 110 causes the connecting ring 250 and the contact part 253 to press against the first button 310. After the first button 310 is triggered, the battery is connected to the light-emitting device 210, the driving device 231, and the speaker 260. The light-emitting device 210 on the turntable 220 emits light, which is evenly transmitted to the light-transmitting part 240 through the light-diffusing part 242 made of light-transmitting material, avoiding the light emitted by the light-emitting device 210 from directly shining into the eyes. Then, the light passes through the pattern 241 and shines outward. The device transmits light through a transmission mechanism. Furthermore, the drive unit 231 drives the turntable 220 to rotate via gears 233 and threads 221, which in turn drives the light-emitting device 210 and the light-transmitting part 240 to rotate, achieving a rotating projection effect. Simultaneously, the speaker 260 emits sound effects that coordinate with the light-emitting device 210, such as animal sounds, enhancing the auditory experience of the rotating projection device and effectively increasing its appeal. In other embodiments, the user can also control the light-emitting device 210 and the speaker 260 via the second button 320, ensuring the ease of use of the rotating projection device.

[0039] As can be seen from the above description, the rotating projection device of this utility model, by setting up a housing 100 and a projection component 200, allows the driving device 231 to stably drive the light-emitting device 210 and the light-transmitting part 240 to rotate, ensuring the working stability of the rotating projection device and improving the user experience; by setting up a bracket 230 and a first button 310, users can quickly and accurately control the start and stop of the projection component 200 by pressing the top cover 110, improving the ease of use of the rotating projection device and increasing its fun factor; by setting up a connecting ring 250, the top cover 110 can be quickly and stably connected to the bracket 230, avoiding the top cover 110 from being moved. To prevent loosening during use, the structure of the rotating projection device is improved, enhancing its structural stability and ease of assembly. The inclusion of a slot 252 and a locking block 111 allows the top cover 110 to be quickly and stably inserted into the slot 252 and fixed to the connecting ring 250 via the locking block 111, thus improving the structural stability of the rotating projection device. The inclusion of a contact part 253 allows the top cover 110 to accurately activate the first button 310 via the connecting block 251, improving the ease of use of the rotating projection device. The inclusion of threads 221 and gears 233 ensures that the drive device 231 can stably and uniformly drive the turntable 220 to rotate, improving the display effect of the rotating projection device.

[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
