An Aerosolization Module for an Aerosol Generating System Having an Optimized Air Path Configuration

Abstract

An aerosolization module for an aerosol generating device includes a bottom end, an opposite top end provided with a mouthpiece, a first air path for the aerosol flow, and a second air path configured to be in fluidic communication with a puff sensor. The first air path includes a first section in which dry air sucked into a first air inlet flows from top to bottom, and a second section in which the aerosol formed by vaporization of the vaporizable material in the dry air flows from bottom to top. The aerosolization device is located inside the module, and the first air inlet is located above the aerosolization device in a bottom to top direction. The mouthpiece is at the top end of the module, and the first air inlet is made through a bottom portion of the mouthpiece. The position of the first air inlet can thus be optimized.
