Abstract

An inhaler for dosing and distributing solids in breathing air has a body provided with an air inlet (5) and with an air outlet (7) which acts as an air suction opening. Inside the body is arranged a per se closed, at least approximately circular chamber (3), to which is tangentially connected an air inflow channel (4) linked to the air inlet and with which is associated an air outflow system linked to the air outlet (7), through which the air can centripetally flow out of the circular chamber (3). The body is constituted by a support (1) which contains the circular chamber (3), the air inflow channel (4) and the air outflow system as well as by a covering lid (2) provided with the air inlet (5) and the air outlet (7). In order to create an inhaler allowing multiple inhalations, a solid reservoir (7) is arranged in the support (1) and a manually controllable dosing device (11) is provided for drawing an amount of solid sufficient for one inhalation from the reservoir (8) and for transporting it into the path of the suction air current.
