Vaporizer assembly

A cartridge for an e-vaping device, the cartridge comprising:

• a reservoir configured to hold a pre-vapor formulation;
• and
• a vaporizer assembly coupled to the reservoir, the vaporizer assembly configured to draw the pre-vapor formulation from the reservoir, the vaporizer assembly further configured to heat the drawn pre-vapor formulation to form a generated vapor, the vaporizer assembly including
• a heating element;
• a conduit assembly including one or more inner surfaces defining a conduit extending through an interior of the conduit assembly, such that the conduit assembly is configured to direct air to flow through the conduit in fluid communication with the heating element;
• and
• a dispensing interface assembly configured to be in fluid communication with both the conduit and the reservoir, the dispensing interface assembly configured to supply the pre-vapor formulation from the reservoir to the heating element, the dispensing interface assembly including a first dispensing interface and a second dispensing interface, the first dispensing interface extending through the conduit and coupled to the heating element within the conduit such that the first dispensing interface is in direct fluid communication with the conduit and the heating element, a portion of the second dispensing interface exposed to an exterior of the vaporizer assembly such that the second dispensing interface is configured to be in direct fluid communication with the reservoir via the portion of the second dispensing interface, the second dispensing interface isolated from direct fluid communication with the heating element by the first dispensing interface, the first dispensing interface isolated from direct fluid communication with the reservoir by the second dispensing interface,
• wherein the first dispensing interface and the second dispensing interface include different wicking materials having different respective capacities to draw pre-vapor formulation, such that the second dispensing interface is configured to restrict a flow of pre-vapor formulation from the reservoir to the first dispensing interface based on the first dispensing interface and the second dispensing interface including said different wicking materials
• wherein the conduit assembly includes a hollow cylindrical inner housing,
• wherein the first dispensing interface extends transversely between opposing inner curved wall surfaces of the hollow cylindrical inner housing,
• wherein the second dispensing interface includes a hollow cylindrical dispensing interface structure that extends around an outer curved wall surface of the hollow cylindrical inner housing, an inner curved wall surface of the hollow cylindrical dispensing interface structure that is proximate to the outer curved wall surface of the hollow cylindrical inner housing being in direct contact with a surface of the first dispensing interface, an outer curved wall surface of the hollow cylindrical dispensing interface structure that is distal to the outer curved wall surface of the hollow cylindrical inner housing being exposed to the exterior of the vaporizer assembly.
