The present application discloses a
crank-connecting rod-type
breathing-synchronized
inhalation apparatus, comprising a housing, wherein a suction
mouthpiece is arranged at the bottom of the housing, and a
medicine bottle is movably arranged inside the housing; an elastic
assembly is arranged at the top of the
medicine bottle and can push the
medicine bottle to move, so that the bottle body compresses a
nozzle, thereby causing the suction
mouthpiece to spray medicine; a mounting
assembly is fixedly arranged on the inner wall of the housing; two ends of a connecting rod
assembly are hinged to the elastic assembly and the mounting assembly, respectively, and the connecting rod assembly has a first state and a second state; a toggle assembly can be deformed by a
suction force generated when a person inhales by means of the suction
mouthpiece, so that the connecting rod assembly is switched from the first state to the second state, thereby removing the restraint placed on the elastic assembly, so that the elastic assembly pushes the medicine bottle, thereby causing the
nozzle to spray a
drug agent; thus, the
inhalation of air is synchronized with the
inhalation of the
drug agent, achieving high sensitivity and good stability; a counting assembly is arranged in an upper cover, and the counting assembly performs a count after the connecting rod assembly is switched from the second state to the first state, which allows a patient to conveniently track the number of remaining doses in the medicine bottle, so that the medicine bottle can be replaced in time.
