11. The atomizer of claim 1 further comprising a seal disposed between said liquid guide channel and said atomizing core, said seal having a capillary channel to channel condensate from said liquid guide channel to a sidewall of said atomizing core.

12. The nebulizer of claim 1, wherein the bracket comprises first and second portions that are opposite in a longitudinal direction; wherein the first portion and the housing define therebetween a reservoir for storing the liquid matrix, the second portion providing retention to the atomizing wick;

at least a portion of the airflow delivery passageway is defined between the first portion and the second portion.

13. The nebulizer of claim 12, wherein the second portion has an airflow guiding surface opposite the first portion, at least a portion of the airflow guiding surface being configured to be disposed obliquely toward the liquid guide groove.

14. The atomizer of claim 1 wherein said atomizing core comprises a porous body and a heating element;

the porous body having a liquid suction surface and an atomizing surface, the liquid suction surface configured to suck the liquid matrix for delivery to the atomizing surface;

the heating element is formed on the atomizing face for heating the liquid matrix.

15. An electronic atomising device comprising an atomiser according to any one of claims 1 to 14 and a power supply means for supplying power to the atomiser.
