Liquid to be atomized is supplied from a wick to the underside of a vibrating orifice plate which pumps the liquid up through atomizing orifices in the plate and ejects the liquid from is upper side; and liquid which is pumped up through the orifices in an elevated region of the plate, but which has not been ejected, is directed back down through larger openings in a lower region of the plate. The liquid also flows back onto the wick which places the liquid in capillary communication along the underside of the plate with the atomizing orifices for reputing and ejection.

1. An atomizing device comprising:a generally horizontally extending plate having an elevated region adjacent a lower region, said elevated region having an upper side and an underside said plate being formed with at least one atomizing orifice extending therethrough in said elevated region and at least one drain opening extending therethrough in said lower region, said at least one drain opening being substantially larger than said at least one atomizing orifice for permitting liquid to flow freely therethrough; a vibration actuator connected to vibrate said plate up and down; and a liquid conductor arranged to conduct liquid from a reservoir to said underside of said elevated region of said plate.
