Abstract
An inhaler vaporizer cartridge includes a housing body with a flow channel, a liquid storage tank, and a vaporizer unit. The vaporizer unit has a wick member and heating member and is liquid-permeable such that liquid is conveyed from the tank through the vaporizer unit to the flow channel. The housing body has a cavity forming the tank and a wick member receiving chamber, and housing is divided by an intermediate wall and a flow channel section. An access opening from the receiving chamber to the flow channel is formed in the intermediate wall and covered by the heating member. Granular grains in the receiving chamber form the wick member and bear against the heating member. The grains form microchannels and are retained by a cover element. An access opening, covered with a liquid-permeable grid structure, establishes a liquid connection from the tank to receiving chamber in the intermediate wall.
