reservoir 22 may be sized and configured to hold enough pre-vapor formulation such that thee-vaping device 60 may be configured for vaping for at least about 200 seconds. Moreover, thee-vaping device 60 may be configured to allow each puff to last a maximum of about 5 seconds. - In at least one example embodiment, the storage medium may be a fibrous material including at least one of cotton, polyethylene, polyester, rayon and combinations thereof. The fibers may have a diameter ranging in size from about 6 microns to about 15 microns (for example, about 8 microns to about 12 microns or about 9 microns to about 11 microns). The storage medium may be a sintered, porous or foamed material. Also, the fibers may be sized to be irrespirable and may have a cross-section which has a Y-shape, cross shape, clover shape or any other suitable shape. In at least one example embodiment, the
reservoir 22 may include a filled tank lacking any storage medium and containing only pre-vapor formulation. - During vaping, pre-vapor formulation may be transferred from the
reservoir 22, storage medium, or both, to the proximity of the heater 14 via capillary action of thewick 28. Thewick 28 may include at least a first end portion and a second end portion, which may extend into opposite sides of thereservoir 22. The heater 14 may at least partially surround a central portion of thewick 28 such that when the heater 14 is activated, the pre-vapor formulation in the central portion of thewick 28 may be vaporized by the heater 14 to form a vapor. - In at least one example embodiment, the
wick 28 may include filaments (or threads) having a capacity to draw the pre-vapor formulation. For example, thewick 28 may be a bundle of glass (or ceramic) filaments, a bundle including a group of windings of glass filaments, and so forth, all of which arrangements may be capable of drawing pre-vapor formulation via capillary action by interstitial spacings between the filaments. The filaments may be generally aligned in a direction perpendicular (transverse) to the longitudinal direction of thee-vaping device 60. In at least one example embodiment, thewick 28 may include one to eight filament strands, each strand comprising a plurality of glass filaments twisted together. The end portions of thewick 28 may be flexible and foldable into the confines of thereservoir 22. The filaments may have a cross-section that is generally cross-shaped, clover-shaped, Y-shaped, or in any other suitable shape. - In at least one example embodiment, the
wick 28 may include any suitable material or combination of materials. Examples of suitable materials may be, but not limited to, glass, ceramic- or graphite-based materials. Thewick 28 may have any suitable capillarity drawing action to accommodate pre-vapor formulations having different physical properties such as density, viscosity, surface tension and vapor pressure. Thewick 28 may be non-conductive. - In at least one example embodiment, the heater 14 may include a wire coil which at least partially surrounds the
wick 28. The wire may be a metal wire. The heater coil may extend fully or partially along the length of thewick 28. The heater coil may further extend fully or partially around the circumference of thewick 28. In some example embodiments, the heater coil 14 may or may not be in contact with thewick 28. - In at least one example embodiment, the heater coil may be formed of any suitable electrically resistive materials. Examples of suitable electrically resistive materials may include, but not limited to, copper, titanium, zirconium, tantalum and metals from the platinum group.

For example, the heater 14 may be formed of nickel aluminide, a material with a layer of alumina on the surface, iron aluminide and other composite materials, the electrically resistive material may optionally be embedded in, encapsulated or coated with an insulating material or vice-versa, depending on the kinetics of energy transfer and the external physicochemical properties required. The heater 14 may include at least one material selected from the group consisting of stainless steel, copper, copper alloys, nickel-chromium alloys, super alloys and combinations thereof. In an example embodiment, the heater 14 may be formed of nickel-chromium alloys or iron-chromium alloys. In another example embodiment, the heater 14 may be a ceramic heater having an electrically resistive layer on an outside surface thereof.
- In at least one example embodiment, the heater 14 may heat pre-vapor formulation in the
wick 28 by thermal conduction. Alternatively, heat from the heater 14 may be conducted to the pre-vapor formulation by means of a heat conductive element or the heater 14 may transfer heat to the incoming ambient air that is drawn through thee-vaping device 60 during vaping, which in turn heats the pre-vapor formulation by convection. - It should be appreciated that, instead of using a
wick 28, the heater 14 may include a porous material which incorporates a resistance heater formed of a material having a high electrical resistance capable of generating heat quickly. - In at least one example embodiment, as shown in
FIG. 2 , thesecond section 72 of thee-vaping device 60 may include apuff sensor 16 responsive to air drawn into thesecond section 72 via anair inlet port 44a adjacent a free end or tip of thee-vaping device 60. Thesecond section 72 may also include a battery 1 and acontrol circuit 200. - Upon completing the connection between the
first section 70 and thesecond section 72, the battery 1 may be electrically connectable with the heater 14 of thefirst section 70 upon actuation of thepuff sensor 16. Air is drawn primarily into thefirst section 70 through one ormore air inlets 44, which may be located along the housing or at theconnector 205. - The power supply 1 may include a battery arranged in the
e-vaping device 60. The power supply 1 may be a Lithium-ion battery or one of its variants, for example a Lithium-ion polymer battery. Alternatively, the power supply 1 may be a nickel-metal hydride battery, a nickel cadmium battery, a lithium-manganese battery, a lithium-cobalt battery or a fuel cell. Thee-vaping device 60 may be usable by an adult vaper until the energy in the power supply 1 is depleted or in the case of lithium polymer battery, a minimum voltage cut-off level is achieved. - In at least one example embodiment, the power supply 1 may be rechargeable and may include circuitry configured to allow the battery to be chargeable by an external charging device. To recharge the
e-vaping device 60, an USB charger or other suitable charger assembly may be used. - Furthermore, the
e-vaping device 60 may include thecontrol circuit 200 and thepuff sensor 16. Thepuff sensor 16 may be configured to sense an air pressure drop and initiate application of voltage from the power supply 1 to the heater 14. Thecontrol circuit 200 may also include aheater activation light 48 configured to glow when the heater 14 is activated. Theheater activation light 48 may include a light-emitting diode (LED) and may be at an upstream end of thee-vaping device 60.
