A device for simulating weather and snowfall process based on elementary school science teaching demonstration

Abstract

The invention relates to the field of environmental simulation technology, and discloses a snowfall process device for simulating weather based on elementary school science teaching demonstration, including an observation area, through the cooperation of an air inlet, a liquid inlet, a threaded rod and a rack, when performing When the snowfall is simulated, the rack is turned over, the bulkiness of the crystal is higher and closer to the shape and bulkiness of the snow, the effect of snowfall simulation is better, and the spray outlet is prevented from freezing due to the low temperature by separately controlling the air inlet and liquid inlet , to avoid blockage, damage to the device, and improve the practicability of installing a device. On the other hand, when the air inlet is opened first, the gas enters first, and the liquid enters later. It is frozen when the time does not flow, and the compressed air can also discharge the residual water in the ejection port, preventing the blockage caused by the water in the ejection port, improving the intelligence of the device, improving the quality of the device, and reducing the production cost.

Description

technical field [0001] The invention relates to the technical field of environment simulation, in particular to a device for simulating weather and snowfall process based on elementary school science teaching demonstration. Background technique [0002] Snowfall is a common natural phenomenon. There is an ancient proverb that auspicious snow heralds a good year. When understanding the benefits of nature, it is also necessary to hold a dialectical view. When the snowfall is too large, it will also bring snow disasters and bring disasters to human beings. It brings a lot of inconvenience and even endangers the safety of life and property. For the younger students, due to their own experience and lack of learning, they cannot fully explain the natural phenomenon reasonably. In order to improve their learning ability and cause Its learning interest urgently needs the invention of a device capable of simulating the snowfall process.

[0002] Snowfall is a common natural phenomenon. There is an ancient proverb that auspicious snow heralds a good year. When understanding the benefits of nature, it is also necessary to hold a dialectical view. When the snowfall is too large, it will also bring snow disasters and bring disasters to human beings. It brings a lot of inconvenience and even endangers the safety of life and property. For the younger students, due to their own experience and lack of learning, they cannot fully explain the natural phenomenon reasonably. In order to improve their learning ability and cause His interest in learning urgently needs the invention of a device that can simulate the snowfall process

[0003] Snow is a snowflake-shaped solid ice that falls from mixed clouds to the ground. When the water on the ocean and the ground is heated and evaporates into the sky, the water vapor moves with the wind to other places. Finally, when they encounter extremely low cold air, Ice crystals are formed and finally fall to the ground, forming snowfall. The traditional snow simulation device uses boring theoretical knowledge to give lectures. Because the minds of primary and middle school students are not yet mature, they cannot digest the boring theoretical knowledge in time, and the traditional simulation Most of the ice produced by the snowfall device is solid ice with large particles, which cannot achieve fluffy ice crystals with a high degree of similarity, which is likely to cause misleading learning for primary and middle school students. The liquid water inside is very easy to freeze and freeze, and blockage will cause damage to the device

[0004] In order to solve the above problems, the inventor proposed a device for simulating the weather and snowfall process based on elementary school science teaching demonstration. The advantage of clogging in low temperature environment solves the problem of poor practicability and easy damage of traditional devices, and ensures that the use of this device to simulate snowfall in the teaching process is more vivid and can arouse students' interest in learning, and the device is not easy damaged, longer lifespan
