The stopping portion 342 may be, but is not limited to, a stopping block disposed in the limiting groove 341, and the stopping portion 342 may also be a corresponding inner sidewall of the limiting groove 341.

In one embodiment, the limiting structure 34 can cooperate with the stop limiter 432 to limit the rotation angle of the sealing sleeve 3 relative to the atomizing assembly 2 to 2 α. For example, referring to fig. 9 and 10, in some embodiments, when the atomizing assembly 2 is provided with 4 liquid inlet holes 25 and the sealing tube sleeve 3 is provided with 4 liquid guide holes 31, the limiting structure 34 can cooperate with the stop limiting member 432 to limit the rotation angle of the sealing tube sleeve 3 relative to the atomizing assembly 2 to 90 °, and when the suction nozzle 4 is rotated, because an avoiding gap with an angle of 45 ° exists between the sealing tube sleeve 3 and the connecting sleeve 43 of the suction nozzle 4, the sealing tube sleeve 3 cannot rotate relative to the atomizing assembly 2 when the suction nozzle 4 is rotated, so as to prevent the liquid inlet holes 25 from being opened due to mistakenly touching the rotating suction nozzle 4. When the suction nozzle 4 rotates beyond an angle of 45 °, since the clearance between the sealing sleeve 3 and the connecting sleeve 43 is eliminated, the limiting member 432 abuts against the stopping portion 342 of the limiting structure 34, so that the suction nozzle 4 can drive the sealing sleeve 3 to rotate together. When the suction nozzle 4 rotates to an integer multiple of 90 degrees, the first convex angle on the suction nozzle 4 coincides with the second convex angle on the liquid storage part 1, the rotation can be stopped, at the moment, each liquid guide hole 31 is aligned and communicated with the corresponding liquid inlet hole 25, and the liquid storage cavity 13 can provide aerosol forming substrate for the atomizing core in the atomizing cavity 24. Referring to fig. 11 and 12, in some embodiments, when the atomizing assembly 2 is provided with 2 liquid inlet holes 25 and the sealing tube sleeve 3 is provided with 2 liquid guide holes 31, the limiting structure 34 can cooperate with the stop limiting member 432 to limit the rotation angle of the sealing tube sleeve 3 relative to the atomizing assembly 2 to 180 °, and when the suction nozzle 4 is rotated, the 90 ° front rotation of the suction nozzle 4 is avoided because a 90 ° avoiding gap exists between the sealing tube sleeve 3 and the connecting sleeve 43 of the suction nozzle 4, so that the sealing tube sleeve 3 cannot rotate relative to the atomizing assembly 2 when the suction nozzle 4 is rotated, and thus the liquid inlet holes 25 can be prevented from being opened due to mistakenly touching the rotating suction nozzle 4. When the suction nozzle 4 rotates beyond an angle of 90 °, since the clearance between the sealing sleeve 3 and the connecting sleeve 43 is eliminated, the limiting member 432 abuts against the stopping portion 342 of the limiting structure 34, so that the suction nozzle 4 can drive the sealing sleeve 3 to rotate together. When the suction nozzle 4 rotates to an integral multiple of 180 degrees, the first convex angle on the suction nozzle 4 coincides with the second convex angle on the liquid storage part 1, and the rotation can be stopped, at the moment, each liquid guide hole 31 is aligned and communicated with the corresponding liquid inlet hole 25 respectively, and the liquid storage cavity 13 can provide aerosol forming substrates for the atomizing core in the atomizing cavity 24.

In this embodiment, when the suction nozzle 4 is rotated relative to the liquid storage component 1, the suction nozzle 4 can drive the sealing tube sleeve 3 to rotate relative to the atomizing tube 22, so that the liquid guiding hole 31 on the sealing tube sleeve 3 is aligned with or staggered from the liquid inlet hole 25 on the atomizing tube 22. It will be appreciated that the vent tube 21 may be integrally formed with the nebulizing tube 22 to enhance the robustness of the overall structure.
