The invention discloses a reservoir-type dry powder inhaling administration system, which comprises a shell. The reservoir-type dry powder inhaling administration system is characterized in that a quantitative feeding mechanism is arranged in the shell, wherein a suction nozzle is arranged at the front end of the shell; the discharging end of the quantitative feeding mechanism is connected to the suction nozzle; a sliding support mechanism is arranged in the shell; the sliding support mechanism is connected to the quantitative feeding mechanism; a vibrating mechanism, by which the quantitative feeding mechanism is driven to vibrate so as to unload materials smoothly, is arranged between the sliding support mechanism and the quantitative feeding mechanism; an anti-dust actuating cover, by which the sliding support mechanism is moved so as to drive the vibrating mechanism and the quantitative feeding mechanism to do actions, is arranged at the front end of the shell; and the anti-dust actuating cover movably sleeves the suction nozzle. The invention aims at overcoming shortcomings in the prior art; and the provided reservoir-type dry powder inhaling administration system is simple in structure, smooth in material unloading, and capable of achieving accurate and quantitative administration and recording administration times.
