The invention discloses an adjustable atomization 
inhalation device for the pediatric 
internal medicine and belongs to the field of atomization devices. The device comprises an upper cover, an atomization 
bottle, an adjustment mechanism, an atomization mechanism and a base, the upper cover and the base are connected to the top and bottom of the atomization 
bottle respectively, and the adjustment mechanism and the atomization mechanism are placed in the atomization 
bottle. According to the device, by installing a gas guide base, a press plate, a rotation shaft, an 
impeller, a spring base and ascrew, exhaled gas conveniently drives the press plate to press the spring base to descend, the content of exhaled gas is obtained, and after expiration is ended, the press plate conveniently reboundsand ascends under the application force of the spring base, so that the screw drives the rotation shaft and the 
impeller to rotate anticlockwise during ascending; an atomized 
medicine solution is quantitatively conveyed into an air 
nozzle connection end through rotation of the 
impeller, the device conveniently adjusts the content of 
inhaled gas next time according to the content of exhaled gas, the atomization 
inhalation amount of the device is effectively and automatically adjusted according to the change of the 
respiratory capacity of a child, the applicability of the device is improved, and the device is conveniently suitable for children, with different respiratory capacities, in different 
age groups.
