1. An ultrasonic mist inhaler, comprising:
a liquid reservoir structure comprising a liquid chamber adapted to receive a liquid to be atomized,
a sonication chamber in fluid communication with the liquid chamber,
a capillary material arranged between the liquid chamber and the sonication chamber to carry the liquid from the liquid chamber to the sonication chamber,
an ultrasonic oscillation component in the sonication chamber, the ultrasonic oscillation component having an atomization surface, and
a capillary material retainer, the capillary material retainer having a retainer body surrounding the atomization surface of the ultrasonic oscillation component, the retainer body having a radial arm extending to the atomization surface, the radial arm being flexible for retaining the capillary material in surface contact with the atomization surface and to not prevent the ultrasonic oscillation component from vibrating to atomize the liquid carried by the capillary material.
