Referring further to fig. 1 and fig. 2, when the atomizing core 3 is inserted into the fixing sleeve 17 from the mounting hole 19, the top of the atomizing core 3 can push the spacer 2, so that the spacer 2 moves along with the atomizing core 3 along the axial direction of the fixing sleeve 17. Thus, under the pushing action of the atomizing core 3, the partition 2 can move from the first position for closing the liquid guide hole 18 to the second position for opening the liquid guide hole 18, and the atomizer is in the use state capable of feeding liquid. At this time, as the liquid guide hole 18 is opened, the liquid inlet hole 312 is aligned and communicated with the liquid guide hole 18, the aerosol-forming substrate in the liquid storage cavity 15 enters the atomizing cavity 311 through the liquid guide hole 18 and the liquid inlet hole 312, the heating element 32 of the atomizing core 3 heats the aerosol-forming substrate provided to the atomizing cavity 311 from the liquid storage cavity 15 through the liquid guide hole 18 and the liquid inlet hole 312 under the action of the electric energy provided by the power supply device, so that the aerosol-forming substrate is atomized to form smoke, and the smoke is sucked by the user through the smoke outlet or the cigarette holder under the suction action of the user.

Simultaneously, the outside of casing 11 is stretched out to at least part of atomizing core 3, and the user can directly be in the liquid state of sealing through observing the bottom that atomizing core 3 stretched out the atomizer, just can judge directly perceivedly that the atomizer is. It should be noted that, when the atomizer is detached from the power supply device, it is generally not easy to determine whether the atomizer is in a liquid-sealing state or a liquid-feeding state. And in the above-mentioned atomizer structure, only need through direct observation atomizing core 3 bottoms whether stretch out the casing 11 of atomizer, perhaps the size of the predetermined distance that the casing 11 of atomizer was stretched out to atomizing core 3 bottoms, just judge very easily that the atomizer is in and seal liquid state or feed liquor state, can prevent effectively that forget the condition emergence of liquid core separation when not using from appearing, lead to producing weeping or aerosol formation matrix and take place to pollute and deteriorate.
