During the packaging and transportation process of the atomizer 1 after the manufacture, the pressing arm 42 of the buckle 40 is located close to the base 10 and tightly pressed against the liquid absorbing end of the liquid absorbing core 21, and the end of the driving arm 43 is exposed. At the moment, the liquid absorption capacity of the liquid absorption end reaches the lowest point, so that liquid leakage in the packaging and transporting process can be prevented. When the atomizer 1 needs to be used, the distal end of the driving arm 43 is pushed into the base 10 by force, the pressing arm 42 moves in a direction away from the base 10, and the pressing on the liquid suction end of the liquid suction core 21 is released, so that the liquid suction core 21 returns to the normal liquid suction capacity, and the atomizer can be used normally. In addition, because the sealing member 30 is made of soft material and the clamp 40 is in interference fit with the sealing member 30, the clamp 40 is fixed after moving to the position away from the base 10, and the operation of the liquid suction core 21 is not interfered.
