A heater assembly includes a container including a cylindrical portion that forms a chamber in which a flavor generating article is contained, and a heater arranged in a peripheral surface of the cylindrical portion. The container includes a first channel extending along a longitudinal direction of the cylindrical portion and located adjacently to the chamber in a direction intersecting with the longitudinal direction of the cylindrical portion, and a second channel extending through the chamber along the longitudinal direction of the cylindrical portion. The first channel is in communication with the second channel.

A bowl for evaporation of a substance for inhalation comprises a cylindrical wall attached to a base. The bowl is made of a colorless single-crystal material selected from the group consisting of: alumina, magnesium-alumina spinel, yttrium-aluminum garnet, and cubic zirconium oxide. The bowl can have any desired color by doping the colorless single-crystal material by a transition metal. The transition metal is selected from a group consisting of: titanium, vanadium, chromium, iron and cobalt. The substance for evaporation can be positioned inside the bowl. In one embodiment, the bowl comprises a tapered cylindrical wall attached to a base. The tapered cylindrical wall can preferably be in shape of a truncated cone to which the base is attached.

A vaporizer includes: a first air outlet channel and a vaporization cavity that are in communication with each other; and a liquid guide member arranged on an end portion of the first air outlet channel that is close to the vaporization cavity, the liquid guide member being in contact with condensate falling off from the first air outlet channel so as to destroy surface tension of the condensate through a downward pulling force, and guiding the condensate into the vaporization cavity.

A cartridge of an e-vaping device includes a housing extending in a longitudinal direction, a reservoir in the housing, a heater in the housing, and an absorbent material at least partially surrounding the sinusoidal shaped member. The reservoir is configured to store a pre-vapor formulation. The heater has a sinusoidal shaped member translating about an elliptical shape to define a channel there through. The absorbent material is in fluid communication with the reservoir.
