Description

Technical Field

[0001] The invention relates to the technical field of atomizers, in particular to an ultrasonic atomization device and application thereof. Background Art

[0002] With the improvement of the quality of life, the application of atomizers is becoming more and more extensive. Common atomizers include air humidifiers for humidifying the air, medical atomizers for treating upper respiratory tract diseases, and other types of atomizers used in the fields of electronic cigarettes. Most of the core components of these atomizers are ultrasonic atomizers, which use electronic high-frequency oscillations and high-frequency resonance of ceramic atomizers to break up the structure of liquid water molecules and produce natural and elegant water mist without heating or adding any chemical reagents.

[0003] Medical staff are prone to heatstroke when wearing airtight protective clothing in the hot summer. In the existing technology, most protective clothing cooling devices use compressors to provide high-speed airflow cooling. This method requires a variety of equipment to cooperate. The use of compressors to supply air to cool protective clothing will consume too much energy and produce too much noise pollution. In addition, when using compressors to supply air to cool protective clothing, the gas delivered is easily mixed with the smell of the machine, which greatly affects the work efficiency of medical staff. In addition, the use of compressors to supply air to cool protective clothing cannot adjust the temperature inside the protective clothing in real time, and the power of the compressor needs to be adjusted manually, which requires additional manpower. In addition, when using compressors to supply air to cool protective clothing, the cooling efficiency is not high because the gas delivered is at room temperature. In addition, the piezoelectric ceramics of most liquid medicine atomization devices are in direct contact with the atomization bottle, which will affect the transmission efficiency of the piezoelectric ceramic vibration and cause uneven atomization particle size.

[0004] For this reason, we are in urgent need of an ultrasonic atomization device and its application. Summary of the invention
