摘要：
A nebulizer with a negative pressure structure includes a nebulization body, a carrying cavity, a nebulizing element and a negative pressure generating element. The carrying cavity is provided for carrying a nebulized liquid and has a through hole. The nebulizing element is installed at the through hole and includes a piezoelectric driving unit and a nebulizing plate disposed on a side of the piezoelectric driving unit. The negative pressure generating element is formed on the carrying cavity and provided for changing the volume of the carrying cavity or removing air from the carrying cavity to reduce the air pressure in the carrying cavity, so as to nebulize a liquid of low surface tension or high viscosity effectively.
