Abstract (en)
[origin: US2022202099A1] To prevent droplets formed by agglomeration of aerosol in an aerosol flow path from reaching the inside of a user's mouth. An atomizing unit comprises an atomizing section, a tank, and a wall that defines at least part of the aerosol flow path. At least part of the wall constitutes part of a lateral wall of the tank. The aerosol flow path includes a first aerosol flow path and a second aerosol flow path. The atomizing unit includes a liquid evacuation section that is disposed in the second aerosol flow path and extends downstream of the second aerosol flow path from a boundary between the first aerosol flow path and the second aerosol flow path. The wall includes a planar portion parallel with a second direction orthogonal to a first direction at the boundary between the first aerosol flow path and the second aerosol flow path. The liquid evacuation section includes a space defined by the planar portion. A ratio of sectional area of the second aerosol flow path and the liquid evacuation section in the second direction to sectional area of the first aerosol flow path in the second direction is larger than 1 and equal to or smaller than 4.0.
