Abstract

A volatile material dispenser includes a base that houses a printed circuit board. The volatile material dispenser also includes a stand assembly and a shroud. The stand assembly is coupled with the base. The stand assembly includes a platform, a stand that extends from the platform, and a manifold that extends from the stand. The manifold contains a circular piezoelectric element. The shroud is positioned on the base. The shroud defines a chimney that is centered along a longitudinal axis. The manifold includes an annular wall that extends from the manifold. A spring is disposed within the manifold and is coaxial with the annular wall. A top end of the spring is wrapped around the annular wall and a bottom end of the spring applies a force against the piezoelectric element.
