[0043] During assembly, the support 100 and the heating element 200 can enclose the air inlet channel a and the atomizing channel b in the air flow channel of the atomizer, thereby simplifying the relevant structure to reduce the required parts, which is conducive to reducing the difficulty of assembly to improve production efficiency, and at the same time is conducive to reducing production costs. In addition, at least part of the first electrode portion 220 constitutes a part of the inner wall of the air inlet channel a, so that the first electrode portion 220 can heat the air inlet airflow in the air inlet channel a, so that the air inlet airflow in the air inlet channel a can be preheated to increase the temperature of the air inlet airflow when it reaches the atomizing channel b, which is conducive to improving the heating effect of the heating element 200 on the atomized liquid, and then it is conducive to improving the atomization efficiency of the atomized liquid. Further, since the first electrode portion 220 can heat the air inlet airflow in the air inlet channel a, the heating portion 210 can heat and atomize the atomized liquid at a lower temperature, which is conducive to reducing power consumption.

The second electrode portion 230 can heat the condensate collected in the liquid collecting tank 140 to accelerate the evaporation of the condensate, thereby helping to reduce the risk of overflow of the condensate in the liquid collecting tank 140 due to excessive accumulation.

[0049] It should be noted that in some other embodiments, the liquid collecting tank 140 may also be disposed on the side of each side of the support 100 where the gas outlet end of the gas outlet tank 130 is located, which is not limited here.

[0052] In some of the embodiments, the portion of the inner wall of the air intake channel a formed by the first electrode portion 220 is the portion through which current flows when the heating element 200 is energized, wherein the portion through which current flows can generate heat, rather than just transferring the heat generated when the heating portion 210 is working, so that the portion of the inner wall of the air intake channel a formed by the first electrode portion 220 can have a higher temperature, thereby improving the heating effect on the intake airflow.

[0053] In some of the embodiments, the portion of the inner wall of the air outlet channel c formed by the second electrode portion 230 is the portion through which current flows when the heating element 200 is powered on, wherein the portion through which current flows can generate heat, rather than just transferring the heat generated when the heating portion 210 is working, so that the portion of the inner wall of the air outlet channel c formed by the second electrode portion 230 can have a higher temperature, thereby improving the heating effect on the aerosol with a lower temperature in the air outlet channel c.

[0054] Specifically, the resistance value of the portion of the first electrode portion 220 through which current flows and the resistance value of the portion of the second electrode portion 230 through which current flows may be the same or different, which is not limited herein.
