Artificial snowing device

Abstract

The invention discloses an artificial snowfall device. The power mechanism finally drives the rotating shaft to rotate. The bottom of the box is an orifice plate with snow holes. The rotating shaft is perpendicular to the orifice plate. The scraper is circumferentially connected with the rotating shaft; the space in the box is a snow-holding space. The invention can control the speed of snowfall and make the artificial snow conform to the shape of natural snow.

Description

technical field [0001] The invention belongs to the field of indoor environment simulation and relates to an artificial snowfall device. Background technique [0002] In scene simulation and experimental environment simulation, artificial snowfall is often used, and the existing artificial snowfall devices often use the following three methods: [0003] 1. Spray (water) snowfall method: This method is to frost on the surface of the contact object (such as the surface of the equipment, the ground, etc.), and the visual effect of natural snow will be obtained after a long time at low temperature, and the form of water mist in the air , and the properties of natural snow are quite different, and it is difficult to simulate the effect of moderate snow and heavy snow; [0004] 2. Cooler frost scraping and snowfall method: as in Chinese patent 93244386.9, the blast pipe blows moist air to the surface of the rotating body, so that the moisture in the air quickly condenses into sno...

Problems solved by technology

[0003] 1. Spray (water) snowfall method: This method is to frost on the surface of the contact object (such as the surface of the equipment, the ground, etc.), and the visual effect of natural snow will be obtained after a long time at low temperature, and the form of water mist in the air , and the properties of natural snow are quite different, and it is difficult to simulate the effect of moderate snow and heavy snow;

[0004] 2. Cooler frost scraping and snowfall method: as in Chinese patent 93244386.9, the blast pipe blows moist air to the surface of the rotating body, so that the moisture in the air quickly condenses into snowflakes on the surface of the rotating body, and is scraped neatly by the groove seat , and then scraped off with a scraper, and the flow air generated by the rotation of the fan sends the snowflakes out; the snow produced by this method has a better visual effect, but the cost is high, the space is large, and the reliability of the equipment is poor;

This method is easy to control the amount of snowfall, but what falls is ice debris, which is far from the nature of snow

[0006] It can be seen that in the existing snowfall devices, either the speed of snowfall cannot be controlled, or the snowflakes with realistic shapes cannot be formed, that is, the existing snowfall devices cannot form the visual effects and properties of realistic natural snow.
