4. The atomizing assembly of claim 1, further comprising a sealing ring, the sealing ring being disposed around an end of the gas-guide tube adjacent to the first sealing member, the sealing ring further abutting against the first step.

5. The atomizing assembly of claim 4, wherein the closed ring includes a sleeve portion and an abutting portion, the abutting portion is formed by extending from one end of the sleeve portion in a radial direction, the sleeve portion is hollow to form a sleeve hole, the sleeve portion is sleeved with the air duct through the sleeve hole, and the abutting portion abuts against the first step.

6. The atomizing assembly of claim 5, wherein an abutting step is convexly arranged on the inner wall of the sleeve hole along the radial direction, and the air duct abuts against the abutting step.

7. The atomizing assembly of claim 1, wherein an outer side surface of the atomizing core adjacent to the first end is circumferentially recessed with a first recessed ring, and the second seal portion is sleeved on the first recessed ring.

8. The atomizing assembly of claim 7, further comprising a second sealing member, said second sealing member comprising a second body and a third sealing portion, a third step being formed between said third sealing portion and said second body, said third sealing portion being configured to receive said second end of said atomizing core, and said second end of said atomizing core abutting against said third step.

9. The atomizing assembly of claim 8, wherein an outer side surface of the atomizing core adjacent to the second end is circumferentially recessed with a second recessed ring, and the third seal portion is sleeved on the second recessed ring.

10. The atomizing assembly of claim 8, further comprising a fixing sleeve, said fixing sleeve being disposed around said second sealing portion, a portion of said atomizing core and said third sealing portion, said fixing sleeve being provided with an oil inlet, said oil inlet communicating said atomizing core with said oil storage chamber.

11. The atomizing assembly of claim 10, wherein said first body defines a fourth step thereon, said retainer sleeve having one end abutting said fourth step.

12. The atomizing assembly of claim 1, further comprising a sealing seat disposed between the sealing cap and the atomizing core, wherein the second end of the atomizing core is inserted into the sealing seat, and the sealing cap abuts against the sealing seat.

13. The atomizing assembly of claim 12, wherein the second sealing portion is disposed on the atomizing core outside the seal seat in a sleeved manner and abuts against the seal seat, and an oil guide hole is formed in the second sealing portion and communicates the atomizing core with the oil storage chamber.

14. The atomizing assembly of claim 13, wherein the seal holder has a groove formed therein, the second end of the atomizing core is inserted into the groove, a mating groove is recessed in a surface of the seal holder on a side of the notch of the groove, and one end of the second seal portion abuts against the mating groove.

15. The atomizing assembly of claim 1, further comprising a sealing cover, wherein an oil filler hole is disposed on said housing, said oil filler hole is in communication with said oil storage chamber, and said sealing cover is detachably mounted on said housing and covers said oil filler hole.

16. An electronic cigarette comprising a battery assembly and the atomizing assembly of any one of claims 1-15, wherein the battery assembly is removably coupled to the atomizing assembly.
