A nebulizer as claimed in claim 4, wherein the first cylindrical screen has a lower port for introducing aerosol and an upper port for allowing aerosol to flow into the second cylindrical screen, the ratio of the cross-sectional area of the lower port to the cross-sectional area of the upper port being 3: (1-2).

6. The nebulizer of claim 5, wherein the filter screen further comprises an abutment portion for abutting against the nebulizer, the abutment portion being provided on the first cylindrical filter screen at a position corresponding to the lower port.

7. The atomizer according to claim 4, wherein said support member is a retaining sleeve, one end of said retaining sleeve being open and the other end being closed, said closed end of said retaining sleeve being provided with a positioning post for engaging and inserting into said second cylindrical screen, the outer peripheral surface of said positioning post contacting the inner sidewall of said second cylindrical screen.

8. The atomizer of claim 7, wherein an end of said positioning post facing away from said closed end is provided with an air-guiding cone.

9. The atomizer of claim 7, wherein said closed end defines a through-hole, and said atomizing housing defines a shut-off ramp at a location corresponding to said through-hole.

10. An atomiser according to any one of claims 1 to 9, wherein the intercepting filter is provided with channels for directing condensate to fall or flow.

11. The atomizer according to any one of claims 1 to 9, wherein said atomizing housing includes a housing and a base mounted to a bottom of said housing, said atomizer further comprising an atomizing tube disposed in said housing and supported on said base, said atomizing tube having said atomizing chamber formed therein, said intercepting filter disposed in said atomizing tube, said intercepting filter being positioned above said atomizing chamber.

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