摘要

PROBLEM TO BE SOLVED: To provide a nebulizer having a nebulization device for nebulizing a substance and a reservoir with a metering chamber.

SOLUTION: The nebulizer 1 includes a metering chamber 6 which has an ultrasonic transducer 4 to drive a horn 5 to be vibrated in an area of a mesh plate 3 and is arranged so as to feed a substance to be nebulized to the nebulization device, and a second chamber 7 arranged to hold and retain any of this substance in excess of the volume held in the metering chamber 6. A fluid sensor 17 is arranged between the metering chamber 6 and the mesh plate 3, to detect that almost all the substance to be nebulized is made into aerosol and the ultrasonic transducer 4 is turned off.
