1. An ultrasonic mist inhaler, comprising:
a liquid reservoir structure comprising a first container forming a liquid chamber adapted to receive liquid to be atomized, the first container comprises a top wall, a bottom wall, and a side wall positioned between the top wall and the bottom wall, the top wall comprises an interior surface, an exterior surface and an upward facing curved surface is formed between the exterior surface and the interior surface of the top wall, the upward facing curved surface forms an aperture to provide access to the liquid chamber, the liquid chamber is formed by the interior surface of the top wall, wherein the interior surface of the top wall is a top surface of the liquid chamber representing a maximum level of the liquid chamber, wherein the bottom wall comprises an interior surface that is a bottom surface of the liquid chamber representing a minimum level of the liquid chamber, and wherein the top surface being in a plane,
a sonication chamber in fluid communication with the liquid chamber, the sonication chamber comprising a piezoelectric transducer, wherein the piezoelectric transducer is disposed adjacent to the top surface of the liquid chamber, the piezoelectric transducer having an atomization surface in a plane perpendicular to the plane of the top surface of the liquid chamber,
a capillary material extending between the sonication chamber and the liquid chamber, and
an annular elastic support for supporting the piezoelectric transducer, the annular elastic support having a plate-shaped configuration and an annular wall surrounding at least a portion of the piezoelectric transducer, the annular elastic support having a passage extending radially through a portion of the annular wall,
wherein the aperture in the top wall of the first container is sized and configured to receive at least a lower wall portion of the annular wall therein, such that a first part of the lower wall portion of the annular wall is configured to engage the upward facing curved surface of the top wall of the liquid reservoir and a second part of the lower wall portion of the annular wall is positioned within the liquid chamber,
wherein a portion of the capillary material passes through the passage of the annular elastic support and penetrates the liquid chamber.
