Abstract
An aerosol generator for an aerosol dispenser is presented where, the aerosol generator has a housing having an inlet part comprising a liquid inlet configured to guide a liquid jet (L) into the housing and an air inlet configured to guide an air flow into the housing. The housing further having an outlet part having an aerosol outlet configured to guide an aerosol (C) of liquid mixed with air out of the housing. The air inlet is configured such that at least part of the air flow entering the housing through the air inlet is obstructed at a distance from the liquid jet (L) entering the housing through the liquid inlet, thereby creating a source of turbulence in the housing to interact with droplets of the liquid jet (L) to prevent coalescence of the droplets.
