4. A nebulizer as claimed in claim 3, wherein the number of the infusion ports is plural, and the number of the ventilation slots is at least one, and at least one of the infusion ports of two adjacent infusion ports is located on a wall of the ventilation slot facing the notch.

5. The nebulizer of claim 1, wherein the infusion port is in the shape of a kidney-shaped aperture or oval.

6. The atomizer of claim 1 wherein said atomizer body further defines structure for defining said atomizing core within said atomizing chamber.

7. The atomizer of claim 6 wherein said limiting structure is a first limiting step disposed on said atomizer body, said atomizing core bottom end abutting said first limiting step;

or, the limiting structure is a positioning groove concavely arranged on the atomization bullet main body, and the atomization core is at least partially accommodated in the positioning groove;

or, limit structure for set up in the spacing boss of first on the atomizing bullet main part, the bottom of atomizing core with the spacing boss butt of first.

8. The atomizer of claim 1 wherein said atomizing core includes a heat generating body for generating heat upon energization and a liquid guide for conveying atomized liquid to said heat generating body.

9. The atomizer of claim 8 wherein said atomizer body comprises a housing having said air outlet at a top end, a base mounted on said housing and having said air outlet open at a bottom end, an atomizer tube mounted in said housing and a vent tube communicating said atomizer tube with said air outlet, said housing defining said reservoir inside said housing outside said atomizer tube and said vent tube, said atomizer tube having said atomizer chamber formed therein, said atomizer tube having said fluid port formed in a wall thereof, said atomizer tube having said vent slot recessed in an inner wall thereof corresponding to said fluid port, said atomizer core having said vent channel defined by an outer wall thereof.
