[0026] Since existing humidifying devices cannot meet the usage requirements, such as without sterilization, and the generated atomized particles are large, it is easy to generate condensed water. Long-term water storage in the cavity is easy to breed bacteria or harmful microorganisms, which is easy to cause pollution. There is also heating and humidifying with complex structures and processes. Due to complexity, the reliability is poor and the cost is expensive. None of the above humidifying means can achieve a long-lasting, reliable, sterile and low-cost humidifying effect;

[0027] Therefore, based on the defects of the existing technology, a humidifying device is designed, which can perform high-temperature sterilization on water, and then vaporize it into wet steam to humidify the air. It humidifies the air faster and more evenly, has a simple structure, is easy to implement in technology, and has a low cost and higher reliability.

The use effect is good and the efficiency is also high. During use: when the temperature detection sensor 6 in the sensor base 7 detects that the temperature signal reaches the high temperature of the specified vaporization, the microcomputer receives the signal from the temperature detection sensor 6 and issues an instruction to the water pump to rotate.
