Abstract

A vaporizer cartridge for an inhaler has a hollow body with a continuous flow channel and liquid storage tank. The tank has an access opening to the channel and a vaporizer unit extending over the entire access opening. The vaporizer unit has a wick member and a heating member. The vaporizer unit is liquid-permeable such that liquid is conveyed at least initially in a capillary manner from the storage tank through the vaporizer unit in the direction of the flow channel. The wick member is formed from a plurality of granular grains which, as a result of their fill and/or formation, form microchannels which establish a fluid connection between the storage tank and the flow channel, continuously from an entry side to an exit side of the wick member. An additional securing means is provided which is holds the granular wick member in position. A corresponding inhaler is also provided.
