Aerosol generator for generating an inhalation aerosol

An aerosol generator for generating an inhalation aerosol from an inhalation liquid, comprising:

• an intake duct having an outlet for guiding air to a mouth of a user and having an inlet for allowing ambient air to be drawn in while the user inhales through the device, and
• a nozzle, arranged for injecting the inhalation liquid into the intake duct,
• wherein the nozzle is arranged for generating a Rayleigh droplet train of the inhalation liquid propagating along a droplet train propagation path, and
• wherein the intake duct comprises:
• at least two first orifices, each of the at least two first orifices having a discharging direction in which respective first air streams discharge from the respective first orifices, wherein the at least two first orifices are arranged to provide the first air streams in mutually colliding discharging directions, the discharging directions of the at least two first orifices being directed towards the droplet train propagation path, the at least two first orifices being configured for providing the respective first air streams to flow from the respective first orifices along the respective mutually colliding discharging directions to and into the droplet train propagation path so as to interact with each other and with the droplet train in the droplet train propagation path,
• at least one second orifice having a discharge direction in which a second air stream discharges into said intake duct substantially in a longitudinal direction to said outlet of said intake duct;
• wherein both said at least two first orifices and said at least two second orifice communicate with said inlet;
• wherein a droplet size decreases with increasing air flow, and
• wherein the discharging directions of the at least two first orifices intersect with the droplet train propagation path at an intersection located downstream of the nozzle and before the outlet of the intake duct.
