5. The atomizer of claim 4, wherein said flare is a diverging horn in the direction of the exit of the gas stream from said gas orifice;

or along the ejection direction of the airflow in the air injection hole, the flaring is in a gradually-expanding funnel shape;

or, along the ejection direction of the airflow in the air injection hole, the flaring is a conical opening with gradually increased caliber.

6. The atomizer of claim 1, wherein said jet assembly defines a liquid receiving channel for receiving condensate, a slot opening of said liquid receiving channel facing said vent.

7. The atomizer according to any one of claims 1 to 6, wherein said vent hole is provided at a central position on said atomizing member, said atomizing surface is located on both sides of said vent hole, at least two heat generating members are provided on said atomizing surface, and at least two of said heat generating members are provided in parallel.

8. The nebulizer of any one of claims 1 to 6, further comprising a vent tube connecting the vent hole and the air guide channel, a first end of the vent tube being inserted into the air guide channel and a second end of the vent tube being inserted into the vent hole.

9. The atomizer of any one of claims 1 to 6, wherein a gap is provided between said air jet assembly and said atomizing surface, said gap defining an atomizing area for mixing air streams emitted from said air jet orifices with aerosol released from said atomizing surface.

10. An aerosol-generating device comprising a nebulizer as claimed in any one of claims 1 to 9.
