It should be noted that a person skilled in the art may make various variations and improvements without departing from the scope of the present invention. Such variations and improvements are all within the scope of protection of the present invention.

[0044] like Figure 1-7 As shown, according to a cooled outdoor integrated projector provided by the present invention, the projector 100 includes a waterproof box body, a middle partition 7 is provided inside the box body, and the internal space of the box body is divided into a waterproof and sealed first space 8 located at the upper part and a second space 9 located at the lower part by the middle partition 7. The first space 8 is equipped with a main control board 28, an optical machine 27 and a heat dissipation module 15, and the second space 9 is equipped with a water cooling system. The pipeline of the water cooling system passes through the middle partition 7 and is connected to the heat dissipation module 15; the water cooling system includes: a fan 17, a water pump 18, a water tank 19, and a water tank radiator 20. The water tank 19 is used to store coolant. The water tank 19, the water pump 18, the water tank radiator 20 and the heat dissipation module 15 are connected in sequence to form a refrigeration circuit; the lens installed in the first space 8 extends out of the box body, and a waterproof sealing structure is provided on the outside of the lens. A plurality of waterproof control components are installed on the outer side of the box body, and a waterproof sealing structure is formed between the waterproof control components and the box body.

[0045] The waterproof projector 100 of this application utilizes a waterproof structure within its first chamber 8, providing exceptionally strong waterproof performance. Its outdoor use is less restricted, making it suitable for most outdoor projection scenarios. Its enclosed structure effectively prevents rainwater penetration, enabling normal operation and stable performance in rainy outdoor environments. Furthermore, an internal dual-circuit water cooling system ensures stable operation of this high-power projector, reducing its size and weight.

[0046] Projector 100 is a high-power projector with high power consumption and heat generation. The housing comprises a top cover 1, left panel 2, front panel 3, right panel 4, rear panel 5, and bottom cover 6, forming a complete cavity. A central partition 7 houses the bulk of the main product assembly. The first compartment 8 is a waterproof and sealed structure. The screw holes on the panels corresponding to the first compartment 8 are blind holes. Major components of projector 100, such as the circuitry and optical engine 27, are housed within the first compartment 8. The second compartment 9 is a non-waterproof and sealed structure that allows for ventilation and heat dissipation.

[0047] The outer surface of the rear panel 5 is provided with a keypad 11, a temperature sensor 12, a power button 13, and a plurality of adapters 14. The keypad 11 is provided with a number of keys that can be used to operate the waterproof projector. The temperature sensor 12 is used to display the internal temperature. The keypad 11 and the temperature sensor 12 are mounted on the rear panel 5 via an aluminum frame 10. A transparent waterproof film is provided on the aluminum frame 10. The transparent waterproof film and the inner wall of the aluminum frame 10 are glued together in a complete circle, and then the aluminum frame 10 is screwed to the rear panel 5. The power button 13 is a waterproof button with a waterproof rating of up to IP67. The adapter 14 includes the connection of necessary signals such as power supply and video signal reception. The adapter 14 is a waterproof connector with a waterproof rating of up to IP67.

[0048] An infrared remote control sensing module is provided on the rear panel 5. The infrared remote control sensing module includes a light-transmitting acrylic plate 31. The light-transmitting acrylic plate 31 is fastened to the rear panel 5 by gluing to form a waterproof sealing structure. The waterproof grade can reach IP67.

[0049] A projection indicator light module is provided on the front panel 3. The projection indicator light module includes a translucent tea-black acrylic plate. The acrylic plate is fastened to the front panel 3 by gluing to form a waterproof sealing structure. The waterproof grade can reach IP67.

[0050] The lens installed in the first space 8 extends from the front panel 3. A lens sealing cover 24 is provided on the outside of the lens. The lens sealing cover 24 is sealed to the front panel 3 via a waterproof adhesive strip 21 and a second O-ring 22. The lens sealing cover 24 is embedded with a soft-glue second O-ring 22. The lens sealing cover 24 is screwed tightly to the front panel 3, compressing the soft-glue second O-ring 22 to deform and achieve waterproofing. A lens lens 26 is provided at the front end of the lens sealing cover 24. The lens lens 26 is sealed to the lens sealing cover 24 via an outer lens pressing piece 25 and an inner first O-ring 23. The lens sealing cover 24 is embedded with a soft-glue first O-ring 23. When the screw on the lens pressing piece 25 is tightened, the lens pressing piece 25 presses the lens lens 26, and the lens lens 26 then compresses the soft-glue first O-ring 23 to deform and achieve waterproofing.

[0051] When the fan 17 in the first space 8 blows toward the heat source on the main control board 28, it actively dissipates heat quickly. However, because the first space 8 is a fully enclosed space, the internal wind pressure will gradually increase, hindering the rotation of the fan 17 until it stops. Therefore, it is necessary to install a waterproof breathable valve 16. When the wind pressure exceeds the rated value of the waterproof breathable valve, the air in the first space 8 will unidirectionally escape through the waterproof breathable valve, simultaneously removing some of the hot air in the first space 8. Furthermore, moisture in the second space 9 cannot enter the first space 8 through the waterproof breathable valve 16, thus ensuring the waterproof requirements of this application.

[0052] The middle partition 7 is provided with a plurality of through holes, through which the pipes of the water cooling system pass and are connected by glue dot connection to form a waterproof sealing structure. There are two groups of water cooling systems inside the box, and the two groups of water cooling systems form two groups of circulating refrigeration circuits. The heat dissipation module 15 is used to dissipate heat from the middle partition 7, thereby dissipating heat to the ambient space of the first space 8. The water tank 19 is used to store coolant to maintain the circulation of the entire water channel. The water pump 18 drives the internal circulation of the entire refrigeration circuit. The water tank radiator 20 is used to help the entire water channel dissipate heat. The fan 17 is directed towards the water tank radiator 20. The fan 17 dissipates heat to the water tank radiator 20, and at the same time forms a specific air duct.

[0053] Water tank radiators 20 are provided on multiple sides of the second space 9, and multiple fans 17 are correspondingly arranged on the outside of the water tank radiators 20. Heat dissipation holes matching the fans 17 are opened on the panels around the second space 9. The fans 17 are waterproof fans with a waterproof grade of up to IP68.

[0054] The projector 100 also includes a bracket 32, which is detachably connected to the projector 100. The bracket 32 ​​includes a base and two X-shaped deformable arms, which are respectively disposed on the left panel 2 and the right panel 4. The bracket 32 ​​can rotate the projector 100 left and right, up and down, and simultaneously raise the height of the projector 100, reducing the possibility of water splashing on the ground.

[0055] The left and right panels 2 and 4 are each provided with a handle 30, and removable foot pads 29 are provided at each of the four corners of the bottom of the projector 100. The projector 100 housing is provided with mounting holes for the handles 30, allowing for easy transport. The foot pads 29 can be installed on the bottom cover 6 for use in situations where mounting the bracket 32 ​​is not possible.

[0056] The top cover 1, bottom cover 6, front panel 3, rear panel 5, left panel 2, right panel 4, center partition 7, lens seal 24, lens pressure plate 25, and foot pad 29 are all made of aluminum. Aluminum has a lower density than steel, which can reduce product weight. Aluminum also helps dissipate heat.

[0057] The projector 100 of the present application fully utilizes a waterproof structure, achieving an IP67 waterproof rating, which is more stringent than the humid environment generally used outdoors, and is conducive to the stable waterproofing of the projector. At the same time, the internal use of an efficient cooling system prolongs the service life of the projector. At the same time, the present application has a simple structure and can be applied to a variety of usage scenarios.
