Abstract

A haze generating device for generating aerosol from a liquid includes at least one chamber in which the aerosol is generated. Each chamber includes a housing including a bottom and a side wall extending from the bottom to a top of the chamber, an ultrasonic transducer at the bottom, and a filter element at the top. The chamber is at least partially filled with a liquid to a filling level such that at least an ultrasound emitting surface of the ultrasonic transducer is immersed in the liquid. The chamber has a directed gas inlet at the side wall that directs a gas stream introduced into the chamber in a direction substantially parallel to a surface of the liquid and substantially along the side wall. The filter element includes guide surfaces that direct the gas stream out of the chamber in a direction substantially perpendicular to the surface of the liquid.
