Abstract
The invention relates to an inhaler component for the formation of a vapor-air mixture and/or a condensation aerosol by evaporation of a liquid material and optionally the condensation of the formed vapor, comprising: a housing, an electric heating element for the evaporation of a portion of the liquid material; a wick with a capillary structure, said wick forming a compound structure with the heating element and automatically supplying the heating element with the liquid material; a carrier plate, preferably a printed circuit board, which carries the compound structure and on which the heating element is electrically contacted; and a capillary gap, formed at least in part by the carrier plate, for automatically supplying liquid material to the compound structure in that an end section of the wick protrudes into the capillary gap. To improve the supply of liquid material to the compound structure, it is proposed that both the front side and the rear side of the carrier plate, at least in some sections, should form the boundary walls of the capillary gap.
