Abstract

A diffusion device (20) includes a housing (22) having a battery disposed therein and adapted to receive a replaceable fluid reservoir for holding a fluid, wherein the fluid reservoir includes a wick for movement of the fluid to a discharge end thereof. The diffusion device (20) further includes a piezoelectric element energized by a power source for vibrating a perforated orifice plate disposed adjacent the discharge end of the wick, wherein the piezoelectric element develops vibratory movement to pump the fluid from the discharge end through the perforated discharge plate and into the atmosphere. A control circuit and light emitting diode ('LED') are disposed in the housing, wherein the control circuit energizes the LED at a particular frequency when the dispenser is active and a voltage developed by the battery is above a threshold voltage.
