In order to enhance the sealing performance, a sealing ring 6 is arranged between the second through hole 17 and the atomizing core. It will be appreciated that the second inlet 14 may be provided in the cartridge seat 12 and the second inlet 14 may be provided in the spacer sleeve. It should be noted that the spacer can be integrally formed with the cartridge holder 12, and the spacer can also be integrally formed with the cartridge case 11 to enhance the structural stability and thus the liquid leakage prevention performance.

Referring to fig. 2 and 7, in some embodiments, when the spacer is a spacer sleeve, a stop step is provided in the spacer sleeve for stopping the atomizing core 2 to limit the moving stroke of the atomizing core 2 moving axially upward. When the atomizing core 2 is stopped by the stopping step, the atomizing core 2 can be limited at the first position, which is beneficial to enhancing the liquid leakage prevention performance of the atomizer. The atomizing core 2 comprises an atomizing pipe 21 which can be axially inserted into the isolation sleeve in a sliding manner, a heating part 22 which generates heat when being electrified, a liquid absorbing part 23 which is used for transmitting aerosol-forming substrate to the heating part 22 and an atomizing support 24 which is used for supporting and fixing the heating part 22, an atomizing cavity is formed inside the atomizing pipe 21, the heating part 22 and the liquid absorbing part 23 are arranged in the atomizing cavity, a first liquid inlet hole 25 is formed in the side wall of the atomizing pipe 21, and the top end of the atomizing pipe 21 is connected with a vent pipe 322. When the atomizing core 2 moves to the second position, the aerosol-forming substrate in the liquid storage cavity 15 can enter the atomizing cavity through the second liquid inlet hole 14 on the base or the isolation sleeve and the first 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 the heat generating member 22, 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 atomizing chamber is guided to the smoking port 333 of the mouthpiece 331 through the vent pipe 322, the threaded pipe 321 or the second guiding pipe 334, and flows into the user's mouth through the smoking port 333, so as to achieve the effect of simulating smoking. 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.

The embodiment of the utility model provides a still provide an aerosol generating device, this aerosol generating device includes the atomizer that any embodiment of the aforesaid provided. 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 only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
