The atomization process of this example is:

first, the electrode 100 supplies power to the heating wire 54, and the heating wire 54 generates heat to heat the atomizing core 50.

At the same time, the oil in the oil reservoir 52 of the atomizing core 50 is transferred to all regions of the core body 51 by conduction through the microporous structure of the core body 51.

Then, the oil in the wick 51 generates smoke under the heating of the heating wire 54. The smoke enters the air passage branch 21 of the air passage member 20 through the air holes 53, then is collected in the collecting portion 22 by conduction in the outlet passage 211, and finally the smoke enters the suction opening 12 of the housing 10 from the collecting portion 22.

In addition, steam is generated only during the process of generating smoke. When the atomizer is not heated, the vapor condenses as a condensate in the passage of the air duct member 20 when it is cooled. And because the delivery channel 211 has the characteristic of gradually increasing the height, the condensate can rapidly slide to the bottom of the delivery channel 211, and drop into the filter cotton 90 through the air holes 53, and is adsorbed by the filter cotton 90, so that the condensate is prevented from flowing back to the oil storage tank 52.
