The atomizer according to claim 4, wherein a flow restriction is disposed in said atomizing chamber, a first end of said flow restriction is connected to said base, and a second end of said flow restriction faces said second end port of said air duct, such that a gap between said second end of said flow restriction and said second end of said air duct forms a flow restriction gap through which air in said atomizing chamber flows into said air duct, said flow restriction gap forming said flow restriction channel.

6. The nebulizer of claim 5, wherein the flow restrictor is a positive post disposed through the nebulization chamber, a central axis of the positive post being collinear with a central axis of the airway tube.

7. The atomizer of claim 3, wherein said atomizing chamber has a positive post disposed therein, said flow-restricting passage includes an air outlet hole disposed in said base and an air inlet defined by a gap between said positive post and said base, said air inlet communicating said atomizing chamber with said air outlet hole, said air outlet communicating with said air-guiding passage.

8. An atomiser as claimed in claim 7, wherein the ratio of the cross-sectional area of the inlet to the cross-sectional area of the outlet is (1.2 to 1.5): 1.

9. the atomizer according to claim 7, wherein the ratio of the diameter of said positive post to the diameter of said exit orifice is (1.2-1.5): 1.

10. an atomiser according to any one of claims 1 to 9, wherein the atomising element is located in the atomising chamber adjacent the restricted flow passage.

11. An aerosol generating device comprising an atomiser as claimed in any one of claims 1 to 10.
