Abstract
The invention relates to an inhaler component for forming a vapor/air mixture or/and condensation aerosol by evaporation of a liquid material (18) and, if appropriate, condensation of the formed vapor, comprising: an electric heating element for evaporating a portion of the liquid material (18); a wick with a capillary structure, which wick forms a composite (10) with the heating element and automatically supplies the heating element with the liquid material (18); a carrier plate (11), preferably a printed circuit board, which carries the composite (10) and on which the heating element is electrically contacted; a capillary gap (16) formed at least partially by the carrier plate (11) and automatically supplying the composite (10) with the liquid material (18), by means of an end portion of the wick extending into the capillary gap (16); a liquid container (19) which contains the liquid material (18) and from which the capillary gap (16) draws the liquid material (18). In order to achieve a compact overall arrangement, it is proposed that the capillary gap (16) at least partially covers the liquid container (19) on the outside, in a view perpendicular to the carrier plate (11).
