Description

Technical Field

[0002] The atomizer mainly inputs high-pressure gas through an air pump, so that the liquid in the atomizer bottle rises to the first air outlet due to negative pressure, and then is dispersed by the high-pressure gas to form atomized liquid particles; in the medical field, the atomizer is mainly used to improve the absorption of liquid drugs, and in the field of daily life, the atomizer is more used for diffusion and humidification. The smaller the particle size of the atomized liquid particles, the better the atomization effect of the atomizer.
