The invention discloses an atomization drug delivery device allowing a drug-delivery speed to be adjusted and used for the respiratory medicine department. The atomization drug delivery device structurally comprises an annular handle, an inward vision plate, an atomizer shell, an atomization drug delivery speed adjustable device, a side cover buckle, a cooling window and a channel 7, and is characterized in that the inner surface of the annular handle and the outer surface of the side cover buckle adhere to each other, the cooling window and the annular handle are of an integrated structure, the cooling window is formed in the left end of the annular handle, the channel 7 and the annular handle are of an integrated structure, the lower end of the inward vision plate is embedded into the upper end of the atomizer shell, and the lower end of the atomization drug deliveryspeed adjustable device is embedded into the upper end of the atomizer shell. According to the design, when the atomization drug delivery device allowing the drug-delivery speed to be adjusted and used for the respiratory medicine department is used, quantified medicine is put into an atomization treatment device, then while atomization medicine is inhaled for treatment, the atomization output rate in the atomization device can be adjusted according to different breath frequencies of all persons, the medicine canbe absorbed more fully, and a batter treatment effect is realized.
