Atomizing device with negative pressure structure

The utility model relates to an atomizing device with a negative pressure structure. The atomizing device with the negative pressure structure comprises an atomizing body, a bearing cavity, an atomizing component and a negative pressure generating component, wherein the bearing cavity is used for bearing atomizing liquid and is provided with a through hole; the atomizing component is arranged at the through hole and comprises a piezoelectric driving unit and an atomizing sheet positioned on one side of the piezoelectric driving unit; the negative pressure generating component is formed on the bearing cavity; and the negative pressure generating component is used for changing the volume of the bearing cavity or removing gas from the bearing cavity so as to reduce the gas pressure of the bearing cavity to effectively atomize low-surface-tension or high-viscosity liquid.
