The nebulizer of claim 2, further comprising an electrode connected to the bottom cover, wherein the sealing support elastically presses the atomizing core against the electrode in a direction perpendicular to an air outlet direction of the air outlet, so that the electrode and the atomizing core are electrically connected.

10. The atomizer according to claim 2, wherein the bottom cover is provided with an air inlet, the air inlet is communicated with the atomizing chamber, and the air inlet and the air outlet are coaxially arranged, wherein projections of the atomizing core and the air inlet in a plane perpendicular to the air outlet direction are not overlapped with each other.

11. The atomizer according to claim 1, wherein said seal mount includes a spacer portion between two of said lower fluid reservoirs, said spacer portion resiliently abutting an inner wall surface of said housing.

12. An electronic atomising device comprising a host and a nebuliser as claimed in any one of claims 1 to 11, the host being connected to and supplying power to the nebuliser.
