Abstract
A volatile material dispenser includes a base that houses a printed circuit board, a stand assembly that is coupled with the base, the stand assembly including a platform, a stand that extends from the platform, and a manifold that extends from the stand, the manifold containing a circular piezoelectric element. The dispenser further includes a shroud that is coupled with the stand assembly and defines a chimney, and a refill comprising a wick, the refill being removably coupled with the manifold. The manifold includes a cylindrical wall that extends upward from the manifold, a spring is disposed within the manifold and is coaxial with the cylindrical wall, and a top end of the spring is wrapped around the cylindrical wall and a bottom end of the spring applies a force against the piezoelectric element.
