Abstract: A vaporizer device is described in which a first air pathway extends from an inlet to a heating element. The heating element is configured to heat air from the first air pathway to produce heated air. A second air pathway extends from the heating element to a mouthpiece and is configured to carry the heated air. The first air pathway is configured to bring the air into thermal contact with at least one component in the second air pathway which absorbs heat from the heated air to heat air in the first air pathway and thereby reduce the energy needed to heat the air.
