Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Referring to Figure 1 - Figure 2 , an embodiment provided by the present invention: An LED optical path heat dissipation structure includes a dust-free inner circulation sealing cover 1. The bottom of the dust-free inner circulation sealing cover 1 is fixedly connected with an inner circulation U-shaped radiator A2. The bottom of the dust-free inner circulation sealing cover 1 is fixedly connected with an inner circulation U-shaped radiator B3. The inner circulation U-shaped radiator A2 and the inner circulation U-shaped radiator B3 are symmetrical. The bottom of the dust-free inner circulation sealing cover 1 is fixedly connected with an optical machine motor 4. The output end of the optical machine motor 4 is fixedly connected with a motor gear 5. The bottom of the inner circulation U-shaped radiator B3 is fixedly connected with a dust-free optical machine upper cover 6. The bottom of the dust-free optical machine upper cover 6 is fixedly connected with an LED lamp board 7. The side wall of the LED lamp board 7 is fixedly connected with a light bucket 98 aluminum 8. The side wall of the light bucket 98 aluminum 8 is fixedly connected with a rear diffuser 9. The side wall of the rear diffuser 9 is fixedly connected with a heat-insulating glass 10. The side wall of the heat-insulating glass 10 is fixedly connected with an LED screen assembly 11. The LED screen assembly 11 includes a bracket A111. The side wall of the bracket A111 is fixedly connected with an LED screen main body 112. The side wall of the LED screen main body 112 is fixedly connected with a bracket B113. The side wall of the bracket B113 is fixedly connected with a front diffuser 12. A lens 13 is arranged on the side wall of the front diffuser 12. The bottom of the lens 13 is fixedly connected with a single-sided air intake inner circulation fan 14. The bottom of the single-sided air intake inner circulation fan 14 is fixedly connected with a dust-free optical machine lower cover 15. The side wall of the dust-free optical machine lower cover 15 is fixedly connected with a radiator fan A16. The side wall of the dust-free optical machine lower cover 15 is fixedly connected with a radiator fan B17. The radiator fan A16 and the radiator fan B17 are symmetrical. The side walls of the radiator fan A16 and the radiator fan B17 are both fixedly connected with LED radiator double fins 18. The side wall of the LED radiator double fins 18 is fixedly connected with a plurality of double radiator metal buckle pins 19. A sealing component is arranged on the side wall of the double radiator metal buckle pins 19. The sealing component is used to seal the speaker.

[0024] Specifically, when the projector starts up, the LED light board 7 lights up as the main light source and heat source. The light source starts from the LED light board 7 and passes through a series of optical elements (light bucket 98 aluminum 8, rear Fresnel lens 9, heat-insulating glass 10, LED screen assembly 11, and front Fresnel lens 12), and finally projects through the lens 13 to form a clear image. The heat generated by the LED light board 7 is first conducted through the radiator of the light bucket 98 aluminum 8. This radiator helps to effectively transfer the heat from the LED light board 7 to the radiator fan A16 and radiator fan B17. The radiator fan A16 and radiator fan B17 create a heat dissipation air flow that enters the interior of the projector through the single-sided air intake internal circulation fan 14. These fans not only help with heat dissipation but also ensure proper air flow during the operation of the projector. The air blown by the fans passes through the internal circulation U-shaped radiator A2 and takes away the heat generated by the LED screen assembly 11. Similarly, the air continues to pass through the internal circulation U-shaped radiator B3 and takes away the remaining heat of the LED screen assembly 11 again. After passing through the internal circulation U-shaped radiator B3, the heat enters the LED radiator double fins 18. Here, the LED radiator double fins 18 continue to absorb and transfer heat to ensure that the temperature of the entire system remains within the safe operating range. The heat dissipation cycle effectively takes away the heat generated by the LED screen assembly 11 and other heat source components through the continuous circulation of the air flow, maintaining the stability and long-term reliability of the projector.

[0025] Referring to Figure 3 , the sealing assembly includes a right-channel sealing cover 20. The right-channel sealing cover 20 is fixedly connected to the side wall of the double radiator metal pin 19. Multiple right-channel sealing covers 20 are symmetrical to each other. A left-channel sealing cover 21 is fixedly connected to the side wall of the right-channel sealing cover 20. The bottom of both the right-channel sealing cover 20 and the left-channel sealing cover 21 is fixedly connected to an upper cavity cover 24. A right speaker unit 22 is fixedly connected between the right-channel sealing cover 20 and the upper cavity cover 24. A left speaker unit 23 is fixedly connected between the left-channel sealing cover 21 and the upper cavity cover 24. A diaphragm 25 is fixedly connected to the bottom of the upper cavity cover 24. A lower cavity cover 26 is fixedly connected to the bottom of the upper cavity cover 24.

[0026] Specifically, the right speaker unit 22 and the left speaker unit 23 are responsible for generating sound signals. They form a sealed connection through the right-channel sealing cover 20 and the upper cavity cover 24, as well as the left-channel sealing cover 21 and the upper cavity cover 24, ensuring that sound does not leak and effectively reflecting and diffusing inside the cavity. A diaphragm 25 is added to the bottom of the upper cavity cover 24 and firmly fixed by the lower cavity cover 26. These diaphragms 25 can not only increase the vibration expressiveness of the speaker unit but also effectively transmit low-frequency signals, thereby improving the overall bass effect. The quality and design of the diaphragms 25 directly affect the richness of the sound quality and the depth of the bass, making the audio experience more immersive and realistic.

[0027] Working principle: When starting the projector for projection, the LED light board 7 is lit by power supply. The light source passes through the aluminum 8 of the light bucket 98, the rear Fresnel lens 9, the heat-insulating glass 10, the LED screen assembly 11, the front Fresnel lens 12, and finally comes out through the lens 13, and is projected onto the wall or the screen to present an image. During this period, the LED light board 7 is the main heat source. The heat dissipation of the LED light board 7 depends on the heat conduction of the aluminum 8 of the light bucket 98 radiator, and then the heat is dissipated by the air flow of the radiator fan A 16 and the radiator fan B 17. The single-sided air intake internal circulation fan 14 inside first passes through the middle of the front Fresnel lens 12 and the LED screen assembly 11 to take away the heat of the LED screen assembly 11, ensuring the normal temperature operation of the LED screen main body 112. Then it passes through the internal circulation U-shaped radiator A 2. The internal heat of the internal circulation U-shaped radiator A 2 will be transferred from the inside to the outside and then sucked away by the radiator fan B 17. The air flow continues to pass through the inside of the machine through the middle of the LED screen assembly 11, the rear Fresnel lens 9, and the heat-insulating glass 10, and continues to take away the heat of the LED screen assembly 11 to ensure the normal temperature operation of the LED screen main body 112. Then it passes through the internal circulation U-shaped radiator B 3. The internal circulation U-shaped radiator B 3 has the same working principle as the internal circulation U-shaped radiator A 2. The internal heat passes through and is conducted to the outside, and then the heat source is sucked away by the double-fin LED radiator 18. The air continues to pass through the internal circulation U-shaped radiator B 3 and returns to the air intake of the single-sided air intake internal circulation fan 14, thus forming a complete heat dissipation cycle. Sound is emitted through the right speaker unit 22 and the left speaker unit 23. Seals are formed by the right channel seal cover 20 and the cavity upper cover 24 and the left channel seal cover 21 and the cavity upper cover 24 to achieve a spatial audio effect. A diaphragm 25 is added to the bottom of the cavity upper cover 24 and fixed by the cavity lower cover 26 to improve the overall bass effect.
