The nebulizer of claim 1, wherein the blocking member comprises a first body and a second body, one end of the second body is disposed in the base assembly, and the other end of the second body extends through the base assembly to the outside; one end of the first body is abutted against the surface of the outer side wall of the atomizing element to seal the liquid inlet hole, and the other end of the first body is inserted into the base assembly and connected with the second body.

3. The atomizer according to claim 2, wherein the base assembly includes a sealing seat, a liquid guide hole is formed in the sealing seat, the atomizing element is inserted into the sealing seat, the liquid inlet hole is communicated with the liquid guide hole, and one end of the first body is inserted into the liquid guide hole and abuts against an outer side wall of the atomizing element to close the liquid inlet hole, so as to prevent the smoke liquid in the liquid storage chamber from flowing into the atomizing element.

4. The atomizer of claim 3, wherein said first body includes a sealing portion detachably inserted into said liquid-guiding hole and abutting against an outer sidewall of said atomizing element to close said liquid-inlet hole, and wherein said sealing portion is separated from said liquid-guiding hole to open said liquid-inlet hole when said second body is pulled.

5. The atomizer according to claim 4, wherein the sealing portion includes a blocking portion and a limiting portion, wherein the limiting portion is formed by extending a circumferential side of an end of the blocking portion away from the second body in a radial direction of the blocking portion, the blocking portion is inserted into the liquid guiding hole and abuts against a side wall of the atomizing element to close the liquid inlet hole, and the limiting portion abuts against an end of the liquid guiding hole away from the liquid storage chamber.

6. The atomizer of claim 2, wherein said first body includes a closure cap covering an outer side wall of said atomizing element to close said fluid inlet hole, said closure cap being separable from said outer side wall of said atomizing element to open said fluid inlet hole when said second body is pulled.

7. The atomizer of claim 6, wherein there are at least two of said blocks, and wherein the connection between the closure caps of each block is breakable to cover the outer side wall of the atomizing element, such that when the second body of one of the blocks is pulled, the closure cap of the pulled block is separated from the other block and opens said fluid inlet hole.

8. Atomiser according to claim 7, characterised in that the closure caps of each closure element are integrally connected and that a plurality of tear-off holes are arranged in series between each closure cap, whereby when the second body of one of the closure elements is pulled, the closure cap of the pulled closure element is separated from the closure caps of the other closure elements at the tear-off holes.

9. The atomizer of claim 2, wherein a guide channel is defined in said base assembly, an end of said first body adjacent to said first body is inserted into said guide channel, and an end of said second body is inserted into said guide channel and connected to said first body.

10. A nebulizer as claimed in any one of claims 2 to 9, wherein the closure further comprises a break through which the first body and the second body are connected, the first body and the second body being splittable at the break when the second body is pulled with force.

11. A nebulizer as claimed in any one of claims 1 to 9, wherein the blocking member is made of silicone.

12. An electronic cigarette comprising the nebulizer of any one of claims 1-11 and a battery pack to power the nebulizer.
