Abstract

The invention relates to an evaporator unit for an inhaler, in particular an electronic cigarette product, comprising an electrically operable heating body, in particular a flat heating body, which has an inlet side and an outlet side, and a plurality of microchannels, each of which extends from the inlet side to the outlet side through the heating body. The heating body is designed to evaporate liquid being transferred through the microchannels by applying a heating voltage. A porous and/or capillary wick structure is arranged on the inlet side of the heating body, said wick structure being fluidically connected or connectable to a liquid store. The wick structure has a shaft which extends through a passage opening of the support, and a collar, which is arranged between the support and the heating body, wherein the diameter of the collar is greater than the diameter of the passage opening of the support.
