Abstract
The cartridge includes a housing, a reservoir containing a pre-vapor formulation, a vapor generator in communication with a central passage, the central passage including a first portion, a second portion and a third portion. The vapor generator is configured to communicate the pre-vapor formulation to the first portion of the central passage. A first air inlet is in communication with the second portion of the central air passage, where the second portion is between the vapor generator and the first air inlet. A dilution air inlet intersects the third portion of the central air passage, where the third portion is between the vapor generator and an outlet of the cartridge. The dilution air inlet defines a dilution air passage that does not pass through the vapor generator. The e-vaping device includes the cartridge.
