Abstract
An atomiser assembly is provided, including: an oscillation chamber having a cavity containing a liquid to be atomized, a liquid inlet configured to provide a supply of the liquid to be atomized to the cavity, an elastically deformable element, and a mesh element comprising a plurality of nozzles; and an actuator configured to oscillate the elastically deformable element, the oscillation chamber and the liquid being contained in the cavity of the oscillation chamber form an oscillation system, in which oscillation of the elastically deformable element by the actuator varies pressure inside the cavity, and the actuator being further configured to oscillate the elastically deformable element at a resonant frequency of the oscillation system to eject liquid contained in the cavity from the cavity through the plurality of nozzles of the mesh element. An aerosol-generating system, an aerosol-generating device, and a method of operating an atomiser assembly are also provided.
