Disclosed is an atomizer drug delivery nozzle, and an intelligently self-adjustable atomizer drug delivery apparatus and a method for using same, characterized in that: a nozzle body (2) is provided with an exhalation detection valve (3) unidirectionally opening toward the outside of a nozzle and an inhalation detection valve (4) unidirectionally opening toward the inside of the nozzle, wherein bodies (3.2, 4.2) of the two valves (3, 4) are respectively provided with a first magnet (3.3) and a second magnet (4.3); a tube wall of the part of the nozzle body (2) that is close to the first magnet (3.3) is provided with a first sensor (3.1), and a tube wall of the part of the nozzle body (2) that is close to the second magnet (4.3) is provided with a second sensor (4.1); the first sensor (3.1) and the second sensor (4.1) are respectively connected to an atomizer control system; and the atomizer control system comprises an intelligent module for detecting a valve state during exhalation and inhalation, and controls a working state of the atomizer according to a received valve opening state detection signal sent by the first sensor (3.1) and the second sensor (4.1). By precisely sensing a patient's breathing action in real time, the atomizer nozzle can realize intelligent self-adjustment, so that the atomizer can be used once opened, has a simplified structure, decreased production costs and a reduced electricity consumption.
