Due to the recessed portion 464, the second air flow portion a2 has a larger air flow rate than the first air flow portion a1 during the suction process, and when the air flow flows through the port of the first trigger air hole 461 during the air flow process, the air pressure change is larger, so that the air flow change amount is relatively amplified, and the detection of the suction air flow change by the air flow sensor 450 is further facilitated. Meanwhile, the above inclined portion 465 also guides the flow of air toward the first trigger air hole 461 during the suction. The port of the first trigger air hole 461 is close to one side in the thickness direction, and is relatively staggered with the first air inlet hole 321 located at the center of the atomizer 300.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
