The disclosure relates to an aerosol therapy device including: a housing; an aerosol generator, which is arranged in the housing; an air inlet, which is formed in the housing upstream of the aerosol generator; and an air outlet, which is formed in the housing downstream of the aerosol generator to administer the aerosol produced, wherein an air flow from the air inlet to the air outlet can be generated by a negative pressure at the air outlet, wherein the air flow flows around the aerosol generator, wherein a truncated-cone-shaped flow channel, the central axis of which extends in a curved manner, is arranged between the aerosol generator and the air outlet.
