[0014] Beneficial effects of the present invention:

[0016] A fast heat dissipation component of a projection device of the present invention is arranged through a unique internal airway, and a lens carrying part is used to carry a lens. The lens undertakes the important task of light transmission during work and the temperature of the lens is relatively high. By carrying a fan in the working chamber and making a unique design of the fan relative to the lens carrying part, a spacing structure is provided between the fan and the lens carrying part, and the fan maintains a certain tilted staggered state relative to the lens carrying part. Therefore, through this unique internal airway design, a gap is left between the fan and the lens and they are staggered by a certain distance, thereby greatly improving the air flow of the fan, and then greatly improving the heat dissipation efficiency of the heat dissipation system, avoiding the problem that the conventional horizontal fitting arrangement of the fan and the lens position affects the air flow and the overall heat dissipation efficiency;

[0017] A fast heat dissipation component of a projection device of the present invention is provided with a heat sink mounting structure. A heat sink mounting body is provided on the outside of a main box body. The heat sink mounting body is used to mount and install the heat sink. The heat sink mounting body equipped with the heat sink is arranged outside the right air intake structure of the working chamber. Therefore, during the operation of the fan, air flowing from the outside to the inside will flow through the heat sink, thereby increasing the air flow rate and flow rate around the heat sink, thereby greatly increasing the wind flow momentum of the heat sink, thereby ensuring and improving the heat dissipation capacity of the heat sink. At the same time, the front and rear transparent parts of the fixed bracket cooperate with the side wall structure of the fixed bracket, so that the mounting method of the heat sink is a hollow setting on all sides, which is beneficial to air circulation and heat dissipation, thereby cooperating with the fan and the setting near the air inlet to further improve the heat dissipation efficiency. At the same time, a built-in heat conductive sheet is By intermittently inputting water flow into the heat conducting plate for auxiliary heat dissipation, auxiliary heat dissipation can be performed on the lens light source cavity and the surrounding areas of the LCD screen, and the overall heat dissipation efficiency of the body is improved in combination with air flow heat dissipation. At the same time, after the water flows through the heat conducting plate, it flows into the heat dissipation inner scales through the diversion tube. The water flow cooperates with the larger contact area of ​​the concave and convex scale wall to achieve a better heat absorption effect of the heat dissipation inner scales. After absorbing heat, the water flow enters the atomizer assembly through the pipeline and is atomized and sprayed out, thereby contacting the outer surface of the heat dissipation inner scales, achieving synchronous heat absorption of the inner and outer surfaces of the heat dissipation inner scales and enhancing the heat dissipation effect. The atomized droplets are discharged to the outside under the action of the airflow blown by the fan, absorbing heat and vaporizing during the discharge process, further ensuring the heat dissipation effect, and the hot mist is discharged to the indoor environment. When it is set and applied to a home projector, it can also function as a humidifier, which is more practical. BRIEF DESCRIPTION OF THE DRAWINGS

The nozzle of the atomizer assembly is oriented toward the heat dissipation inner scale 45 and is inclined in the opposite direction of the working cavity 23. A heat conducting sheet 42 is provided in the mainframe box body 11 near the projection lens head 13. A diverter tube 43 is provided in the heat conducting sheet 42. The diverter tube 43 is communicated with the water mist heat dissipation cavity 47. A radiator carrier 20 is installed on the front side of the mainframe box body 11. A radiator 17 is installed in the radiator carrier 20. The radiator 17 is a fin type. The radiator 17 is connected to the equipment in the mainframe box body 11 through a heat pipe to achieve heat absorption. The radiator carrier 20 includes a fixed bracket 29. A transparent portion 33 is provided in the fixed bracket 29. The direction of airflow movement is to enter from the radiator 17 and blow out from the heat dissipation inner scale 45. A stronger heat dissipation effect is achieved by setting a double heat dissipation device.

[0029] During operation, the fan 22 is started to introduce external low-temperature airflow through the right side structure of the working chamber 23 to cool the inside of the projector. The longitudinal protrusions 27 of the heat dissipation sheet 26, the inner wall heat dissipation scales 45 and the gap 28 structure of the heat dissipation plate 15 make it convenient for the hot air in the body to circulate along the gap 28 and the heat is fully conducted to the heat dissipation plate 15. At the same time, the contact area with the external air is increased through the longitudinal protrusions 27 and the gap 28, thereby improving the heat dissipation effect, thereby achieving the effect of improving the heat dissipation performance. At the same time, the lens mounting part 21 is used to mount the lens. The lens undertakes the important task of light conduction during work. The temperature of the lens is relatively high. By setting the position of the fan 22 relative to the lens mounting portion 21, there is a spacing structure between the fan 22 and the lens mounting portion 21. At the same time, the fan 22 maintains a certain tilted and staggered state relative to the lens mounting portion 21. Therefore, through this unique internal airway design, a gap is left between the fan and the lens and they are staggered at a certain distance from each other, thereby greatly improving the air flow of the fan, and then greatly improving the heat dissipation efficiency of the heat dissipation system, avoiding the problem that the conventional horizontal fitting setting of the fan and the lens position affects the air flow and the overall heat dissipation efficiency. The radiator carrier 20 is used to mount and install the radiator 17. The radiator carrier 20 equipped with the radiator 17 is arranged on the right side of the working chamber 23. In addition, during the operation of the fan 22, the air flowing inward from the outside will flow through the radiator 17, increasing the air flow rate and flow rate around the radiator 17, thereby greatly increasing the wind flow momentum of the radiator, thereby ensuring and improving the heat dissipation capacity of the radiator. At the same time, the front and rear transparent parts 33 of the fixed bracket 29 cooperate with the side wall structure of the fixed bracket 29, so that the mounting method of the radiator 17 is a hollow setting on all sides, which is beneficial to air circulation and heat dissipation, thereby cooperating with the fan 22 and the setting near the air inlet to further improve the heat dissipation efficiency. A water storage structure is arranged outside the body to intermittently input water flow into the heat guide plate 42 for auxiliary heat dissipation, which can assist in heat dissipation of the lens light source cavity and the surrounding side of the liquid crystal screen, and cooperate with Airflow heat dissipation improves the overall heat dissipation efficiency of the body. At the same time, after the water flows through the heat conductive sheet 42, it flows into the heat dissipation inner scales 45 through the diversion tube 43. The water flow cooperates with the larger contact area of ​​the concave and convex scale wall part 46 to achieve a better heat absorption effect of the heat dissipation inner scales 45. After absorbing heat, the water flow enters the atomizer assembly through the pipeline 48 and is atomized and sprayed out, thereby contacting the outer surface of the heat dissipation inner scales 45, achieving synchronous heat absorption of the inner and outer surfaces of the heat dissipation inner scales 45, enhancing the heat dissipation effect, and the atomized droplets are discharged to the outside under the action of the airflow blown by the fan. Heat is absorbed and vaporized during the discharge process, further ensuring the heat dissipation effect, and the hot mist is discharged to the indoor environment. When it is set to be used on a home projector, it can also function as a humidifier, which is more practical.

[0030] The spray flow rate of the atomizer assembly is less than 50ml / h. The projector and the temperature and humidity detection probe installed indoors are connected and synchronized via a network connection, so that the atomizer assembly automatically adjusts the spray flow rate to ensure the heat dissipation effect while avoiding the problem of reduced projector service life caused by excessive humidity in the environment where the projector is located.
