9. The nebulizer of claim 1, wherein the receiving chamber corresponds in position to and is in fluid communication with the liquid conducting aperture.

10. The nebulizer of claim 8, wherein the extension comprises a first extension and a second extension, the first extension and the second extension being disposed at two ends of the main body portion.

11. The nebulizer of claim 10, wherein the liquid conducting holes comprise a first liquid conducting hole and a second liquid conducting hole; a first capillary element is accommodated in the first liquid guide hole, and a second capillary element is accommodated in the second liquid guide hole; the first capillary element and the second capillary element are respectively contacted with two ends of the main body part.

12. The nebulizer of claim 11, wherein the first capillary element extends from the end of the body portion in a direction opposite the first extension, and the second capillary element extends from the end of the body portion in a direction opposite the second extension.

13. The atomizer of claim 1, wherein said atomizing assembly further comprises a seal, said liquid conducting orifice being located on said seal.

14. The atomizer of claim 13, wherein said atomizing assembly further comprises a support frame having at least one support arm disposed thereon for securing said liquid-conducting element, said receiving chamber being defined in said support frame.

15. The atomizer of claim 14, wherein said support and said seal cooperatively define at least one securement aperture for securing said liquid directing element.

16. An atomizer, comprising:

the device comprises a shell, a liquid storage cavity and an atomizing assembly, wherein the liquid storage cavity is arranged in the shell and is used for storing liquid matrix, and the atomizing assembly is used for atomizing the liquid matrix and is positioned on one side of the liquid storage cavity;

the atomization assembly comprises a heating element and a liquid guide element; the liquid guide element comprises a main body part and at least one extension part, and the heating element is connected to the main body part;

wherein the atomization assembly defines at least one fluid-conducting hole for providing a path for liquid substrate in the reservoir chamber to pass to the fluid-conducting element, and the extension portion extends from the body portion in a direction away from the reservoir chamber.

17. An aerosol-generating device comprising a nebuliser according to any one of claims 1 to 16, and power supply means for providing the nebuliser with an electrical drive.
