[0022] To further elaborate on the technical means and effects adopted by the present utility model to achieve the intended utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present utility model as follows.

[0023] Embodiment 1:

[0024] A ventilation device for a recreational vehicle provided in this embodiment, as shown in Figure 1 , Figure 2 , Figure 3 , includes an upper cover 1 provided outside the vehicle and a lower cover 2 provided inside the vehicle. A first ventilation opening 3 communicating with the outside of the vehicle is provided on the upper cover 1, and a second ventilation opening 4 communicating with the inside of the vehicle is provided on the lower cover 2; an exhaust fan assembly is provided between the upper cover 1 and the lower cover 2. The exhaust fan assembly includes a base 5 and a fan 6. The fan 6 is connected to the base 5. One side of the fan 6 communicates with the first ventilation opening 3, and the other side communicates with the second ventilation opening 4; a telescopic light-shielding plate 7 is provided on the second ventilation opening 4; specifically, at least one side of the telescopic light-shielding plate 7 is provided with a guiding member, and the guiding member is connected to the lower cover 2. In this embodiment, the telescopic light-shielding plate 7 adopts a foldable light-shielding curtain, which is integrally connected in a plurality of W shapes in sequence. The guiding member adopts a straight rod, and the light-shielding curtain is slidably sleeved on the straight rod; a ventilation hole is opened on the vehicle body. The base 5 and the lower cover 2 are used to connect to the vehicle body. The base 5 and the lower cover 2 pass through the ventilation hole and are fixedly connected to each other. Part of the base 5 and part of the lower cover 2 are attached to the vehicle body to complete the fixation to the vehicle body; the upper cover 1 is sleeved outside the fan 6 and can play a protective role.

[0025] The fan 6 can extract the air inside the recreational vehicle through the second ventilation opening 4 and then discharge it outside through the first ventilation opening 3. The inside of the recreational vehicle is in a negative pressure state, which is convenient for the outside air to flow in; the design of the telescopic light-shielding plate 7 can block the light on hot summer days, reduce the heat entering the recreational vehicle, and is telescopic, so that the blocked area can be freely adjusted.

[0026] To prevent flying insects from entering the inside of the recreational vehicle, as shown in Figure 4 , Figure 5 , an insect-proof net 8 is provided on the second ventilation opening 4 or the base 5. The lower cover 2 or the base 5 is detachably connected to the insect-proof net 8, which is convenient for removing and cleaning. In this embodiment, the insect-proof net 8 is connected to the base 5 by a buckle, which is convenient for disassembly and assembly; the projected area of the insect-proof net 8 on the horizontal plane is smaller than the projected area of the second ventilation opening 4 on the horizontal plane. The insect-proof net 8 can pass through the second ventilation opening 4, so that the insect-proof net 8 can be directly removed without disassembling the machine, which is easy to clean.

[0027] For the convenience of lighting, a light strip 9 is provided on the lower cover 2; the light strip 9 is arranged around the side of the lower cover 2. The design of the light strip 9 facilitates temporary lighting at night; the light strip 9 is arranged in a circle and can be used as an ambient light. In this embodiment, the light strip 9 adopts an embedded structure, and the outer surface of the light strip 9 is flush with the outer surface of the lower cover 2, making the overall appearance neat and clean.

[0028] For the convenience of adjusting the air output volume, an electric push rod 10 is provided between the exhaust fan assembly and the upper cover 1, and the electric push rod 10 is used to drive the upper cover 1 to lift; the first ventilation opening 3 is located at the bottom of the upper cover 1. The electric push rod 10 can increase the height of the upper cover 1, which also increases the height of the first ventilation opening 3, thereby expanding the distance between the first ventilation opening 3 and the vehicle body, reducing the resistance during air output, and thus increasing the air output volume.

[0029] For reliable adjustment of the air output volume, one side of the upper cover 1 is rotatably connected to the base 5, and the electric push rod 10 is used to drive the upper cover 1 to rotate relative to the base 5 and thereby lift the upper cover 1. The electric push rod 10 can drive the upper cover 1 to rotate, which also changes the height of part of the upper cover 1, and thus changes the height of the first ventilation opening 3, and can also change the air output volume.

[0030] For the reliability of the upper cover 1, the upper cover 1 includes a protective shell 11 and a ventilation base 12. The protective shell 11 is rotatably connected to the base 5. The protective shell 11 is sleeved on the ventilation base 12. One side of the ventilation base 12 is hinged to the protective shell 11, and the other side is slidably connected to the base 5; the first ventilation opening 3 is located on the ventilation base 12. The protective shell 11 is used to improve the protection performance, can block rainwater, and reduce direct sunlight; the ventilation base 12 is used to arrange the first ventilation opening 3, and the ventilation base 12 can rotate relative to the protective shell 11, which can further expand the adjustment angle of the first ventilation opening 3.

[0031] In this embodiment, a horizontally arranged waist-shaped hole 15 is provided on the base 5, and a slider 16 is provided on the ventilation base 12. The slider 16 is slidably arranged in the waist-shaped hole 15.

[0032] For reliable ventilation, the first ventilation opening 3 is located on the side away from the hinge joint of the upper cover 1 and the base 5, and the adjustable angle is the largest; one end of the electric push rod 10 is hinged to the base 5, and the other end is hinged to the protective shell 11.

[0033] When lifting electrically, the electric push rod 10 pushes the protective shell 11 to rotate upward, the upper cover 1 drives the ventilation base 12 to move upward, one end of the ventilation base 12 rotates relative to the protective shell 11, and the other end slides relative to the base 5, preventing the ventilation base 12 from jamming with the base 5.

[0034] To improve the structural strength, reinforcing ribs 13 are provided on the inner wall surface of the protective shell 11. Part of the reinforcing ribs 13 are located between the protective shell 11 and the ventilation base 12, leaving a gap between the protective shell 11 and the ventilation base 12 for ventilation. The remaining part of the reinforcing ribs 13 are located between the protective shell 11 and the base 5, leaving a gap between the protective shell 11 and the base 5 for ventilation, resulting in better overall ventilation.

[0035] To ensure reliable air flow, a wind guide plate 14 is provided on the first ventilation opening 3. In this embodiment, the end of the wind guide plate 14 is inclined towards the fan 6. The design of the wind guide plate 14 can direct the air flow and is conducive to the rapid circulation of air.

[0036] To reflect heat, a reflective layer is provided on the telescopic light-shielding plate 7. In this embodiment, the reflective layer is made of silver-coated material, and the silver-coated material is on the inner side. The reflective layer can effectively reflect heat, achieving the effects of being cool in summer and warm in winter.

[0037] The above is only a preferred embodiment of the present invention and does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
