Referring to fig. 2, 8 and 10, the atomizing core 2 is provided with a limiting member 4, and the liquid storage member 1 is provided with a limiting structure 5 for guiding the limiting member 4 to move along a predetermined path. In the process of axially moving the atomizing core 2 relative to the liquid storage component 1, the limiting component 4 moves along a preset path limited by the limiting structure 5, and under the cooperative action of the limiting component 4 and the limiting structure 5, the axial moving distance and/or the circumferential rotation angle of the atomizing core 2 relative to the liquid storage component 1 can be limited. Referring to fig. 4, fig. 5 and fig. 6, when the limiting member 4 is stopped by the limiting structure 5 to limit the atomizing core 2 at the first position, the liquid inlet hole 25 on the atomizing core 2 is shielded by the partition member 3, so that the liquid inlet hole 25 is isolated from the liquid storage cavity 13, and the liquid storage cavity 13 cannot provide aerosol-forming substrate to the atomizing core 2 through the liquid inlet hole 25, thereby achieving the effect of liquid core separation. Referring further to fig. 1, fig. 2 and fig. 3, when the limiting structure 5 stops the limiting member 4 to limit the atomizing core 2 at the second position, the liquid inlet hole 25 on the atomizing core 2 is not shielded by the partition 3, and the liquid inlet hole 25 is communicated with the liquid storage cavity 13, so that the liquid storage cavity 13 can provide the aerosol-forming substrate to the atomizing core 2 through the liquid inlet hole 25, and the atomizing core 2 can normally atomize the aerosol-forming substrate provided by the liquid storage cavity 13, so that the user can normally use the atomizer.

Thus, during the axial movement and/or circumferential rotation of the atomizing core 2 with respect to the reservoir 1: when the atomizing core 2 moves axially and/or rotates circumferentially to the first position, the liquid inlet hole 25 on the atomizing core 2 is positioned in the isolating sleeve and is shielded by the isolating sleeve, so that the liquid inlet hole 25 and the liquid storage cavity 13 are isolated from each other, and the effect of liquid core separation in a liquid sealing state is achieved; when the atomizing core 2 moves axially and/or rotates circumferentially to the second position, the liquid inlet hole 25 on the atomizing core 2 moves out of the isolation sleeve and is exposed, so that the liquid inlet hole 25 is communicated with the liquid storage cavity 13, and the atomizer is in a liquid supply state capable of supplying liquid to the atomizing core 2. It is understood that, referring to fig. 7, 8 and 10, in some embodiments, when the partition 3 is a spacer, a plurality of liquid inlet holes 25 may be circumferentially spaced on the outer side wall of the atomizing core 2, and when the atomizing core 2 moves and/or rotates to the first position, the spacer may simultaneously shield the plurality of liquid inlet holes 25.

When the atomizing core 2 is located at the second position, the aerosol-forming substrate in the liquid storage cavity 13 can enter the atomizing cavity through the liquid guide hole 6 on the isolating sleeve and the liquid inlet hole 25 on the atomizing pipe 21, the liquid absorbing member 23 uniformly and stably transmits the aerosol-forming substrate entering the atomizing cavity to generate heat, and the heat generating member 22 generates heat when being powered on, heats and atomizes the aerosol-forming substrate to form smoke which can be sucked by a user. The smoke generated in the atomising chamber is introduced into the user's mouth via the smoking port 14 to provide the user with a simulated smoking effect. It is understood that the heating element 22 can be, but is not limited to, a heating wire or a ceramic heating element 22, and the wicking element 23 can be a wicking cotton or a porous ceramic. Referring further to fig. 2, 5 and 11, in some embodiments, in order to enhance the sealing performance, a first sealing ring 7 is disposed at a connection portion of the atomizing pipe 21 and the sliding hole 16, and a second sealing ring 8 is disposed at a connection portion of the atomizing support 24 and the through hole 15.

The embodiment of the utility model also provides an aerosol generating device, which comprises the atomizer provided by any one of the embodiments and a power supply device for supplying power to the atomizer. Since the aerosol generating device has all the technical features of the atomizer provided in any of the above embodiments, it has the same technical effects as the atomizer described above.

The above description is intended to be illustrative of the preferred embodiment of the present invention and should not be taken as limiting the utility model, but rather, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the utility model.
