The invention discloses a dosing speed-adjustable respiratory department atomization doser, structurally comprising an annular handle, an inward vision plate, an atomizer shell, an atomization dosingspeed-adjustable device, a side cover buckle, a cooling window and a channel 7, and characterized in that the inner surface of the annular handle is bonded with the outer surface of the side cover buckle, the cooling window forms an integrated structure with the annular handle, and is located at the left end of the annular handle, the channel 7 forms an integrated structure with the annular handle, the lower end of the inward vision plate is embedded and mounted at the upper end of of the atomizer shell, and the lower end of the atomization dosing speed-adjustable device is embedded and mounted at the upper end of the atomizer shell. When the dosing speed-adjustable respiratory department atomization doser is used, after a fixed amount of drug is put into an atomization treatment device, while the atomized drug is sucked for treatment, the atomization output rate of the atomizer can be adjusted according to different breath frequency of each person, so that the drug is absorbed more fully, and a better treatment effect is achieved.
