Digital sand table can fully reflect the characteristics of the location and achieve a vivid and varied dynamic visual effect; it is a new experience for visitors and can produce strong resonance, which is more intuitive than traditional sand table models. In order to achieve a better experience effect, CAVE technology is combined with digital sand table technology to build a multi-dimensional CAVE digital sand table, giving people a new experience and making the content displayed in the sand table more experiential.

[0003] Since CAVE requires the use of a water mist spray device, the humidity inside the hemispherical space is high, and there is a large amount of water mist in the air. This water mist cannot dissipate in a very short time, resulting in a large amount of water stains accumulating on the mirror surface of the projection device. These water stains will blur the projection and affect its use. Utility Model Content

[0006] The projection device includes a mounting frame, and an air pump and a filtering device are fixedly installed on both sides of the lower end of the mounting frame, respectively. A projector is installed at the middle position of the lower end of the mounting frame, and an air blowing ring is installed at the tail of the projector. An anti-fog device is installed at the other end of the projector, and the anti-fog device is connected to the air pump and the filtering device through a hose, the air blowing ring is connected to the air pump through a hose, and the air pump and the filtering device are connected through a hose.

[0007] Furthermore, a plurality of heat sinks used in conjunction with an air blowing ring are fixedly disposed on the outer wall of the projector, and the cross-section of the heat sink is arc-shaped.

[0008] Furthermore, the heat sinks are provided in two groups, each group of heat sinks are evenly distributed on the outer wall of the projector, and the two groups of heat sinks are staggered.

[0009] Furthermore, the anti-fog device includes an annular shell, a partition plate is fixedly arranged in the middle position of the annular shell, the upper and lower ends of the partition plate are respectively a blowing chamber and an air suction chamber, and the inner ring wall of the annular shell is respectively provided with air holes used in conjunction with the blowing chamber and the air suction chamber, the blowing chamber is connected to the air pump, and the air suction chamber is connected to the filtering device.

[0010] Furthermore, the inner ring surface of the annular shell is V-shaped, wherein the air holes of the blowing cavity and the air suction cavity are both arranged at an angle.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the utility model, after turning on the projector, the staff then turns on the air pump, and then the air pressure inside the suction chamber decreases, so that air starts to be sucked in to absorb the air in front of the projector and the water mist in the air, thereby preventing the water mist from sticking to the lens of the projector. After the air enters the suction chamber, it enters the interior of the filter device, thereby removing the water mist in the air. The removed gas enters the interior of the air pump, and after passing through the air pump, it enters the blowing ring and the blowing chamber through a pipeline. The gas discharged from the blowing ring can cool the surface of the projector, and the gas discharged from the blowing chamber can blow the mirror of the projector, thereby cleaning the mirror and preventing the mirror surface from fogging.
