Aerosol inhalation device for department of pediatrics

An aerosol inhalation device for the department of pediatrics is provided with a rapid drug delivery mechanism. The rapid drug delivery mechanism comprises a first spring and a drug delivery pin. The first spring is arranged in a drug bottle storage area and is in a deformation energy storage state. The drug delivery pin penetrates through and is rotationally arranged on the cavity wall of a shell. The inner end of the drug delivery pin is located in the inner cavity of the shell and used for clamping the first spring to maintain the deformation state of the first spring, and the outer end of the drug delivery pin is located outside the shell and used for controlling the inner end of the drug delivery pin to move to relieve the clamping effect on the first spring. Therefore, the first spring can push a medicine bottle to move towards an annular partition plate to release medicine by utilizing self elastic potential energy. According to the invention, medicine supply to pediatric patients is facilitated, and p
