INHALATION DEVICE

PURPOSE: To improve an inhalation apparatus as to a flow technique to be easier and more secure to use, by providing a structure in which a supplying container for chemicals is arranged in the inside of a measuring drum, and an air inlet conduit and a connecting conduit make V-shape each other and extend toward a dosing chemical amount. CONSTITUTION: A supplying container 3 is formed of the inside 5 of a measuring drum D. An air inlet conduit 9 and a connecting conduit 8 extend toward the periphery of the measuring drum D so as to make the V-shape each other. This forms an acute-angled conduit structure and is exposed to a suction air flow so that a precisely measured powder amount removed from the supplying container 3 is discharged from the V-shaped vertex area. To achieve this purpose, the measuring drum D has a partial chamber 11. The partial chamber 11 comprises a bore 14 in the rotating sleeve 15 of the measuring drum D, and the rotating sleeve 15 is rotatably fixed between a circular wall 16 and a circular wall partition 17.
