The atomizer of claim 10 wherein said porous body has a longitudinal direction, a width direction and a height direction that are perpendicular to each other, said porous body having a length that is greater than a width of said porous body, and wherein only a sidewall of said sealing element is disposed between said porous body and said housing along said length of said porous body, said sidewall providing a seal.

12. The nebulizer of claim 10, wherein the bracket comprises a support post comprising a longitudinally-extending flow-guiding cavity, the support post being embedded in the inner cavity of the sealing element.

13. The nebulizer of claim 10, wherein a ventilation structure is defined between the frame and the sealing member, the ventilation structure comprising a notch provided on the sealing member and a ventilation slot provided on the frame, the notch communicating with the ventilation slot and the reservoir, the ventilation slot communicating with the interior cavity of the outlet tube.

14. An atomizer, comprising:

the liquid storage device comprises a shell, wherein an air outlet pipe and a liquid storage cavity surrounding the air outlet pipe are arranged in the shell;

a porous body, and a heating element coupled to the porous body, the porous body having a flat liquid suction surface;

a support member including a receiving cavity in which the porous body is held in a direction perpendicular to a longitudinal axis of the housing;

the support element comprises a first liquid inlet and a second liquid inlet, and further comprises a separation wall for separating the first liquid inlet from the second liquid inlet, wherein the bottom end surface of the separation wall is contacted with the liquid absorption surface of the porous body so as to separate the liquid absorption surface into two areas.

15. An electronic atomising device comprising an atomiser according to any one of claims 1 to 14 and a power supply assembly for providing an electrical drive to the atomiser.
