DIFFUSION DEVICE

摘要

A battery powered diffusion device includes a housing having an internal power supply and adapted to receive a replaceable fluid container for holding a fluid, the fluid container including a wick for movement of fluid to a discharge end thereof. The diffusion device further includes a piezoelectric element that is energized by a battery to vibrate a perforated orifice plate disposed adjacent the discharge end of the wick. The piezoelectric element provides sufficient vibratory movement in a dispensing state to pump the fluid from the discharge end through the orifice plate and into the atmosphere as aerosolized particles. Diameters of perforations extending through the orifice plate are between about 4.63 microns and about 5.22 microns.
