Humidification principle:when the water in the water tank is transported to the sprinkler on the top of the humidifier, the water is evenly sprinkled on the top of the wet film. The sprinkler ensures that the water is evenly distributed on the wet film material. The water penetrates downward along the wet film material and wets all the layers inside the wet film. The wet film humidifier is absorbed by the wet film material at the same time, forming a uniform water film; when the dry wind passes through the wet film material, the dry air and the wet wet film surface have a larger area of ​​contact, thereby achieving a larger amount of water evaporation. A large number of water molecules are sent into the space to be humidified with the wind, increasing the humidity of the air, thereby achieving the purpose of humidification.
