Abstract
The e-vaping device includes a housing, and a vaporizing heater within the housing. A cartridge within the device defines a reservoir containing a pre-vapor formulation. A chip on an end of the cartridge defines a via in fluid communication with the reservoir. The chip includes an ejector in fluid communication with the via, where the ejector is configured to eject droplets of the pre-vapor formulation towards the vaporizing heater. The method of making the device includes connecting a chip to an end of the cartridge, where the ejector ejects droplets of the pre-vapor formulation towards the vaporizing heater. The method of operating the device includes supplying a first electrical current to the vaporizing heater to energize the vaporizing heater and supplying a second electrical current to the ejector to energize the ejector and eject droplets of a pre-vapor formulation from the ejector towards the vaporizing heater.
