Claim:
1. A nebulizer with a negative pressure structure, comprising: a nebulization body; a negative pressure generating element, formed right adjacent to the carrying cavity, for changing the volume of the carrying cavity, wherein when the volume of the carrying cavity decreases, the one-way exhaust valve allows air to exit but not enter the carrying cavity, and after the volume of the carrying cavity restored a negative air pressure in the carrying cavity is created, so that a pressure in the carrying cavity is smaller than atmospheric pressure, and an external air will move to a hole of the nebulizing plate, wherein the carrying cavity comprises an inner cup body and an outer cup body, and the negative pressure generating element comprises a pressing portion, the one-way exhaust valve and the pressing portion are disposed at positions of an upper section in the outer cup body, wherein when a user physically and mechanically presses the pressing portion, the pressing portion is moved in a direction towards the inner cup body to decrease a volume occupied by the negative pressure structure and push air in the volume of the negative pressure structure out from the one-way exhaust valve to produces a negative pressure state in the carrying cavity.
