Artificial snowing device

Abstract

Disclosed is an artificial snow apparatus, a rotary shaft being rotated by a dynamic mechanism and vertical relative to an orifice plate that is positioned on the bottom of the case body and has orifices allowing snow to pass through. A scraper contacting and working with the orifice plate is circumferentially connected to the rotary shaft and arranged in the upper side of the orifice plate, with space in the case body for storing snow. The invention is capable of controlling snow speed with the appearance of artificial snow more close to 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.
