1. An aerosol-generating device, comprising:
an aerosolisation chamber configured to receive an aerosol-generating article comprising an aerosol-forming substrate;
an air inlet configured such that ambient air may flow therethrough and into the aerosol-generating device;
an airflow path fluidly connecting the air inlet with the aerosolisation chamber,
wherein the air inlet is disposed in a recessed portion of an outer surface of the aerosol-generating device, and
wherein the recessed portion comprises a length of more than 10 mm and is configured to prevent blocking of the air inlet by a user; and
a housing,
wherein the recessed portion is provided in an outer surface of the housing,
wherein the outer surface of the housing is parallel to a longitudinal axis of the aerosol-generating device,
wherein the recessed portion further comprises a base and at least one sidewall,
wherein the base of the recessed portion is parallel to the longitudinal axis of the aerosol-generating device,
wherein the sidewall is inclined away from the base such that the sidewall is not perpendicular with respect to the base,
wherein the air inlet is arranged in the sidewall or in a transition between the base and the sidewall.
