Inhaler, particularly electronic cigarette product, and computer program product

An inhaler, comprising:

• at least one evaporator device having at least one electrical evaporator for evaporating liquid supplied to the at least one electrical evaporator;
• an electronic control device for controlling and/or regulating the at least one evaporator device,
• wherein the at least one evaporator device is associated with a plurality of liquids in such a way that a composition and/or the vapour production rate of vapour/aerosol produced by the at least one evaporator device is adjustable and/or modifiable in a targeted manner, as the electronic control device is configured for individual control of one or more of the at least one evaporator device,
• the at least one evaporator device comprises at least one carrier, wherein each carrier of the at least one carrier has at least one evaporator and a standardized interface for electrical contacting of the evaporator of the at least one evaporator,
• wherein the evaporator is formed by a block-shaped heating element made of an electrically conductive material, and
