A base for an e-vaping device is configured to couple with multiple cartridges configured to generate separate, respective dispersions. The cartridges may include one or more atomizer assemblies or vaporizer assemblies. The base may include multiple connectors electrically coupled to the power supply. The connectors may be configured to couple multiple dispersion generators to a power supply of the base. The base may include control circuitry configured to independently control dispersion generation by dispersion generators coupled to the base. The control circuitry may independently control dispersion generation by the first and second cartridges based on cartridge information accessed through at least one of the first and second connectors. The control circuitry may control dispersion generation by controlling power supplied to the dispersion generators.

Multiple dispersion generator e-vaping device

An electronic vaping device includes a power supply section, a heater assembly section, and a cartridge. The power supply section includes a power supply. The cartridge section includes a reservoir configured to store a pre-vapor formulation, and a wick in fluid communication with the pre-vapor formulation. The heater assembly section is connected to the power supply section and the cartridge. The heater assembly section includes at least one plate heater in physical contact with a portion of the wick. The at least one plate heater is selectively electrically connectable to the power supply.

Three-piece electronic vaping device with planar heater

A cartridge for an e-vaping device enables simultaneous vaporization of different pre-vapor formulations to form a vapor for vaping by an adult vaper. The cartridge includes a dispensing interface coupled to a plurality of reservoirs and a heater coupled to the dispensing interface in a housing. The dispensing interface may include a trunk and separate roots extending into separate reservoirs, such that the dispensing interface draws different pre-vapor formulations from the reservoirs to the trunk via the separate roots. The heater is coupled to the trunk, such that the heater is operable to simultaneously vaporize the different pre-vapor formulations drawn into the trunk.

Combined cartridge for electronic vaping device

A cartridge may include a housing, a liquid supply reservoir in the housing and configured to store a pre-vapor formulation, a vaporizer, and a porous plug. The vaporizer may be in liquid communication with the liquid supply reservoir. The vaporizer may be configured to generate a vapor from heating a portion of the pre-vapor formulation. The porous plug may be connected to the housing and separated from the liquid supply reservoir. The porous plug may be permeable to the vapor. The porous plug may enclose a flavoring additive contacting a storage material. The flavoring additive may be configured to at least partially elute from the storage material or at least partially volatilize from the storage material if the vapor flows through the porous plug. An e-vaping device may include the cartridge.

Methods to add menthol, botanic materials, and/or non-botanic materials to a cartridge, and/or an electronic vaping device including the cartridge

A base for an e-vaping device is configured to couple with multiple cartridges configured to generate separate, respective dispersions. The cartridges may include one or more atomizer assemblies or vaporizer assemblies. The base may include multiple connectors electrically coupled to the power supply. The connectors may be configured to removably couple with various cartridges. Different cartridges may be interchangeably coupled with the connectors. Different cartridges may be swapped from the connectors. The base may include control circuitry configured to independently control dispersion generation by cartridges coupled to the base. The control circuitry may control dispersion generation by controlling power supplied to the cartridges. The control circuitry may control electrical power supplied based on information accessed from one or more of the cartridges.

E-vaping device cartridge holder

A cartridge for an e-vaping device enables separate vapors to be formed proximate to separate, respective ends of the cartridge. The cartridge includes multiple reservoirs and separate vaporizer assemblies coupled to separate reservoirs on opposite ends of the reservoirs. The separate reservoirs may hold separate pre-vapor formulations. The separate vaporizer assemblies may draw separate pre-vapor formulations from separate reservoirs towards opposite ends of the cartridge and vaporize the separate pre-vapor formulations via operation of separate heaters proximate to the separate ends. The separate heaters may be independently controlled to independently control vapor formation at the separate ends. The heaters may be controlled to independently control vapor formation rates proximate to the separate ends. The heaters may be controlled to form separate vapors at least one of simultaneously, concurrently, and at different times.

Cartridge for electronic vaping device

A cartomizer of an electronic vaping device includes a heater circuit which is located adjacent an air passage thereof. The heater circuit includes an electrically resistive heater in electrical communication with a secondary coil. A wick extends across the air passage. The wick is configured to draw pre-vapor formulation from a reservoir toward the heater. The heater is configured to heat the pre-vapor formulation to a temperature sufficient to vaporize the pre-vapor formulation and form a vapor. The cartomizer is connectable to a power supply component which includes a power source in electrical communication with a primary coil. The power supply component is configured to induce sufficient voltage in the secondary coil of the heater circuit such that the secondary coil is configured to heat the heater and vaporize the pre-vapor formulation when the primary coil is powered by the power source.

Electronic vaping device and components thereof

A cartridge of an electronic vaping device includes a housing extending in a longitudinal direction. The housing includes a sidewall, a transverse wall at the first end of the sidewall, and an inner tube integrally formed with the housing. The sidewall is generally cylindrical and a first end and a second end. The transverse wall includes at least one outlet therein. The inner tube extends in the longitudinal direction. The inner tube is concentrically positioned with respect to the sidewall. The inner tube communicates with the at least one outlet. The cartridge also includes a reservoir between the sidewall and the inner tube. The reservoir is configured to contain a pre-vapor formulation.

Electronic vaping device

A liquid aerosol formulation for an electronic smoking article includes an aerosol former, water, nicotine, and an acid including tartaric acid. The acid is included in an amount sufficient to provide the liquid aerosol formulation with a pH ranging from about 4 to about 8.

Liquid aerosol formulation of an electronic smoking article

An e-vapor device may include a pre-vapor sector and a heater structure arranged in thermal contact with the pre-vapor sector. The pre-vapor sector includes a reservoir and a dispensing interface. The pre-vapor sector is configured to hold and dispense a pre-vapor formulation. The heater structure is configured to vaporize the pre-vapor formulation to generate a vapor. The heater structure includes a base wire and a heater wire coiled around the base wire. The base wire is insulated from the heater wire. As a result of the heater design, the heater structure is stiffer and more robust than other related heaters in the art, thus allowing more options for its implementation.

E-vapor device including a compound heater structure

An e-vapor device may include a pre-vapor sector and a heater structure arranged in thermal contact with the pre-vapor sector. The pre-vapor sector is configured to hold and dispense a pre-vapor formulation. The heater structure includes a base wire and a shell layer coating the base wire. The base wire is insulated from the shell layer. The shell layer includes at least one recessed portion between a first unrecessed portion and a second unrecessed portion. The at least one recessed portion is a thinner section of the shell layer that is configured to vaporize the pre-vapor formulation to generate a vapor. As a result of the heater design, the heater structure is stiffer and more robust than other related heaters in the art, thus allowing more options for its implementation.
