Claims (14)

1. An atomizer, comprising:

a housing, at least a portion of the housing defining a reservoir for storing a liquid substrate;

an atomizing assembly comprising a heating element for heating the liquid substrate to generate an aerosol and electrically conductive pins in electrical communication with the heating element;

a metal seat for supporting the atomizing assembly;

a protective member configured to surround at least a portion of the conductive pin and positioned between the metal seat and the conductive pin, thereby separating the conductive pin from the metal seat.

2. A nebulizer as claimed in claim 1, further comprising a sealing element for supporting the metal seat, the protector being attached to or forming part of the sealing element.

3. The nebulizer of claim 2, wherein the sealing member comprises a receiving groove, at least a portion of the atomizing assembly is received within the receiving groove, and the protective member is disposed within the receiving groove.

4. The atomizer of claim 1 or 2, wherein said atomizing assembly further comprises a fluid conducting element, said protective member being configured as a raised structure extending longitudinally of said housing in a direction toward said fluid conducting element.

5. The atomizer of claim 4, further comprising a sealing member for supporting said metal seat, said raised structure comprising a first raised portion, said sealing member having a bore disposed therethrough for said conductive pin, said first raised portion defining at least one guide slot along which said conductive pin can enter said bore.

6. The atomizer of claim 5, wherein said first boss defines two guide slots, one of said two guide slots capable of receiving a positive conductive pin and the other of said two guide slots capable of receiving a negative conductive pin; and a partition wall is arranged between the two conductive grooves, so that the positive conductive pin and the negative conductive pin are spaced.

7. A nebulizer as claimed in claim 5, wherein the first boss is provided as a thin-walled structure.

8. The nebulizer of claim 5, further comprising a second protrusion disposed on the sealing element, wherein the sealing element comprises a vent aperture, and wherein the second protrusion is disposed around at least a portion of the vent aperture.

9. The atomizer of claim 8, wherein said first and second lobes are intermittently disposed.

10. The atomizer of claim 1, further comprising an end cap having a conductive connector disposed thereon, said conductive pin being electrically connected to said conductive connector.

11. The atomizer of claim 2, wherein at least one fluid conducting aperture is disposed in said metal seat, said sealing member including a fluid conducting ramp facing said reservoir, said fluid conducting ramp for directing at least a portion of the liquid substrate within said reservoir into said fluid conducting aperture.

12. The nebulizer of claim 11, wherein the flow directing ramp defines a portion of the reservoir chamber such that the cross-sectional area of the reservoir chamber decreases in a longitudinal direction.

13. An atomizer, comprising:

a housing at least a portion of which defines a reservoir for storing a liquid substrate;

an atomization assembly comprising a heating element for heating the liquid substrate to generate an aerosol;

the base is used for supporting the atomization assembly, and at least one liquid guide hole is formed in the base; and

a sealing element comprising a flow directing bevel towards the reservoir cavity for directing at least a portion of the liquid substrate stored inside the reservoir cavity into the flow directing aperture.

14. An aerosol-generating device comprising an atomiser as claimed in any of claims 1 to 13, and a power supply assembly for providing electrical drive to the atomiser.
