Abstract
A humidifier including a base enclosure defining a reservoir to be filled with liquid, an opening disposed above the reservoir, and a discharge orifice communicating therewith; a humidification unit mounted on the base, covering the opening and adapted to produce dispersion of liquid retained by the reservoir; the humidification unit being separable from the base along a joint extending around the opening; and a seal mechanism including a channel for receiving liquid disposed to form a seal preventing the passage through the joint of liquid dispersed by the humidification unit. This arrangement provides a vapor seal for power units that expel vapor through a distinct discharge orifice.
