The first end 90 and the second end 95 are configured to contact the reservoir 50 (e.g., Figure 3 The core 85 contains a steam pre-mixing agent (shown and discussed below). The central portion 100 of the core 85 extends above at least one inlet 70. In at least one exemplary embodiment, the core 85 is formed of at least one of cellulose material, glass material, glass fiber, and cotton.

[0073] In at least one example embodiment, the core is formed of cellulose filter paper having a thickness from about 0.6 mm to about 1.0 mm.

[0081] In at least one example embodiment, the cylinder and Figure 2 The same as in the diagram, but shown in an exploded view to illustrate additional parts of end cap 55. For example... Figure 3 As shown, the end cap lateral wall 60 includes a portion 160 ( Figure 2 As shown in the diagram, the portion has an outer diameter smaller than the inner diameter of the housing 15a at the second end 30. Therefore, a portion of the end cap lateral wall 60 can be received within the second end 30 of the housing 15a. The portion 160 of the end cap lateral wall 60 can be held in place within the second end 30 of the housing 15a by a friction fit, snap-fit ​​fit, or any other suitable connection. For example, an adhesive can be used to hold the portion 160 of the end cap lateral wall 60 within the housing 15a. Alternatively, the portion 160 of the end cap lateral wall 60 and the second end 30 of the housing 15a can comprise a threaded portion providing a threaded connection between the end cap 55 and the housing 15a.

[0082] In at least one example embodiment, such as Figure 3 As shown, the inner tube 45 is integrally formed with and coaxially positioned within the housing 15a.

[0091] In at least one example embodiment, such as Figure 5 As shown, cylinder 10 and Figure 2 , 3Similar to 4, but the transverse end wall 35 is shown as a generally planar surface having at least one outlet 40 therein. In other example embodiments, the transverse end wall 35 may be convex or recessed.

[0092] Figure 6 This is a perspective view of a power supply section and a heater assembly section according to at least one example embodiment, with the housing of the section shown as transparent to show the interior portions of the power supply section and the heater assembly section.

[0093] In at least one example embodiment, such as Figure 6 As shown, the power supply section 105 includes a housing 15c extending in the longitudinal direction. For illustrative purposes only, the housing 15c is shown as transparent. The housing 15c has a first housing end 225 and a second housing end 230. The first housing end 225 is configured to connect to the heater assembly section 200.

[0094] In at least one exemplary embodiment, the power supply section 105 and the heater assembly section 200 may be connected via a connector 700. The connector 700 may be at least one of a threaded connector, a snap-fit ​​connector, a friction-fit connector, and any other suitable connector. The connector 700 may be formed at least partially of a conductive material as described in U.S. Application No. 15 / 224,608, filed July 31, 2016, the entire contents of which are incorporated herein by reference. Because the connector 700 does not contact the cylinder 10, there is no physical contact between the connector 700 and the reservoir, the pre-conditioning of the steam contained in the reservoir, or both.

[0095] In at least one example embodiment, the power supply section 105 includes a battery 110.

[0096] In at least one example embodiment, the heater assembly section 200 includes a housing 15b containing a support 120 configured to support a heater 115 thereon.

[0097] In at least one exemplary embodiment, heater 115 may be a planar heater, such as a plate heater as described herein. Support 120 may be generally cylindrical, annular, or both. Support 120 defines an airflow passage 600 therethrough. Heater 115 is suspended on support 120 and supported thereon by leads 125a, 125b. Leads 125a, 125b extend through support 120 and extend to (or through) connector 700. Connector 700 may be formed of a conductive material and includes at least one air passage therethrough.

[0098] In at least one exemplary embodiment, heater 115 may be formed of any suitable resistive material. Examples of suitable resistive materials may include, but are not limited to, titanium, zirconium, tantalum, and metals from the platinum group. Examples of suitable metal alloys include, but are not limited to, stainless steel, nickel-containing, cobalt-containing, chromium-containing, aluminum-titanium-zirconium-containing, hafnium-containing, niobium-containing, molybdenum-containing, tantalum-containing, tungsten-containing, tin-containing, gallium-containing, manganese-containing, and iron-containing alloys, as well as superalloys based on nickel, iron, cobalt, and stainless steel. For example, depending on the energy transfer kinetics and desired external physicochemical properties, heater 115 may be formed of nickel aluminide, materials with an alumina layer on the surface, iron aluminide, and other composite materials, and the resistive material may optionally be embedded in, encapsulated in, or coated with an insulating material, or vice versa. Heater 115 may comprise at least one material selected from the group consisting of: stainless steel, copper, copper alloys, nickel-chromium alloys, superalloys, and combinations thereof. In exemplary embodiments, heater 115 may be formed of a nickel-chromium alloy or an iron-chromium alloy. In another embodiment, heater 115 may comprise a ceramic or alumina layer having a resistive layer, such as a platinum layer, on its outer surface. In at least one embodiment, heater 115 may comprise at least one of ceramic, alumina, or zirconium oxide. In at least one embodiment, heater 115 is formed of platinum-alumina or platinum-zirconia, and the dimensions of heater may be approximately 1.6 mm by approximately 3.5 mm by approximately 0.25 mm.

[0099] In at least one example embodiment, the heater 115 is formed of a platinum alloy. The platinum alloy may contain up to about 10% by weight of rhodium. The platinum alloy may contain up to about 30% by weight of iridium. This alloy can have a lower temperature coefficient of resistance, so that the resistance of the heater does not increase as much as that of a pure platinum heater. This allows for a larger initial resistance, thereby reducing the initial current. The lower current allows a wider range of batteries and power circuits to be used with the heater.

[0100] In at least one example embodiment, heater assembly section 200 includes two or more heaters 115 electrically connected in parallel or series. When connected in parallel, the total starting resistance can be about 0.86 ohms, while when connected in series, the total starting resistance increases so that a lower starting current is required for heater operation.

[0101] In at least one example embodiment, the heater 115 has a length from about 2.0 mm to about 64.0 mm, a width from about 1.0 mm to about 4.0 mm, and a thickness from about 0.1 mm to about 1.0 mm.

[0102] At least two electrical leads 125a and 125b extend from heater 115 and electrically connect heater 115 to battery 110. Leads 125a and 125b may be made of nickel or stainless steel. Heater 115 may have a resistance of approximately 2.6 ohms at 25 degrees Celsius and approximately 5.6 ohms at 350 degrees Celsius. Leads 125a and 125b may be approximately 10 mm long and can support temperatures up to approximately 400 degrees Celsius.

[0103] In at least one example embodiment, the heater 115 has at least one of a width and a length smaller than at least one of the width and length of the core 85 when the heater 115 contacts the core 85. Therefore, when the heater 115 contacts the core 85, the surface of the heater 115 is in complete contact with the core 85 and a portion of the core 85 extends beyond the boundary of the heater 115. The heater 115 can heat the vapor pre-mixed material in the core 85 by thermal conduction. Alternatively, heat from the heater 115 can be conducted to the vapor pre-mixed material by means of a heat-conducting element, or the heater 115 can transfer heat to the ambient air drawn in during vaporization through the electronic vaporizer 5, which in turn heats the vapor pre-mixed material by convection.

[0104] In at least one example embodiment, battery 110 may be a lithium-ion battery or a variant thereof, such as a lithium-ion polymer battery. Alternatively, battery 110 may be a nickel-metal hydride battery, a nickel-cadmium battery, a lithium-manganese battery, a lithium-cobalt battery, or a fuel cell.

[0105] In at least one example embodiment, the power supply 110 may be rechargeable and may include circuitry configured to allow the battery 110 to be charged by an external charging device.

[0106] In at least one example embodiment, the power supply section 105 may also include control circuitry 135 and sensor 130.

[0107] In at least one example embodiment, sensor 130 is configured to generate an output indicating the magnitude and direction of airflow in the electronic vaporizer 5. Control circuit 135 receives the output from sensor 130 and determines (1) whether the direction of the airflow indicates suction (contrast blowing) at outlet 40 and (2) whether the magnitude of suction exceeds a threshold level. If these suction vaporizer conditions are met, control circuit 135 electrically connects power supply 110 to heating element 115; thus, heating element 115 is activated. That is, control circuit 135 electrically connects first lead 125a and second lead 125b (e.g., by activating a heater power control transistor forming part of control circuit 135) such that heating element 115 is electrically connected to power supply 110. In an alternative embodiment, sensor 130 may indicate a voltage drop, and control circuit 135 may activate heating element 115 in response to this.

[0108] In at least one embodiment, the power supply section 105 may be contained in, adjacent to, or within an end cap 145 of the power supply section 105, or in and adjacent to a lamp 48. Control circuitry 135 may be configured to initiate illumination of the lamp 48 when the heater 115 is activated. The lamp 48 may contain one or more light-emitting diodes (LEDs). The LEDs may contain one or more colors (e.g., white, yellow, red, green, blue, etc.). Furthermore, the heater activation lamp 48 may be arranged to be visible to an adult vaper. Additionally, the lamp 48 may be used for e-vaping system diagnostics or to indicate that recharging is in progress. The lamp 48 may also be configured to allow an adult vaper to activate, deactivate, or both activate and deactivate the heater activation lamp 48 for privacy.

[0109] In at least one embodiment, the control circuit 135 may include a time period limiter. In another embodiment, the control circuit 135 may include a manually operable switch for an adult vaporizer to initiate heating. The time period for supplying current to the heating element 115 may be set or preset depending on the amount of vapor pre-mixed material to be vaporized.

[0110] In at least one embodiment, at least one air inlet 300 may be positioned adjacent to the power supply end cap 145. At least one air inlet 300 may extend through the housing 15c. In other embodiments, at least one air inlet 300 may extend through a portion of the housing 15b of the heater assembly section 200.

[0111] Next, the operation of the e-vapor device 5 in generating steam will be described. For example, in response to suction at outlet 40, air is primarily drawn into cylinder 10 through at least one air inlet 300. The air passes through air inlet 300, enters the space around the battery, passes through the air passage in the connector, through the support 120 in the heater assembly section 200, enters the air passage 47 in cylinder 10, and passes through outlet 40 of cylinder 10. If the control circuit 135 detects the above-described steam suction conditions, the control circuit 135 initiates power supply to the heating element 115, causing the heating element 115 to heat the steam premix in the core 85.

[0112] When activated, the heating element 115 can heat a portion of the core 85 for less than about 10 seconds.

[0113] Figure 7 This is an enlarged perspective view of a heater assembly according to at least one example embodiment.

[0114] In at least one example embodiment, such as Figure 7 As shown, as about Figure 6 As described, leads 125a and 125b are supported by support 120, such that heater 115 is suspended over air passage 600 extending through support 120. Leads 125a and 125b may extend through holes in support 120. Leads 125a and 125b may be arranged such that no part of heater 115 contacts support 120. In other exemplary embodiments, portions of heater 115 directly contact support 120.

[0115] The support 120 may be formed of MACOR material, which is a machinable glass-ceramic available from Corning, Inc.

[0116] Figure 8 This is an exploded view of a four-piece electronic vaporizer according to at least one example embodiment.

[0117] In at least one example embodiment, such as Figure 8 As shown, the cylinder 10 and heater assembly section 200 are... Figures 1 to 7The electronic vaporizer 5 is identical to the one described above, but instead of the power supply section, it includes an adapter 800 and a commercially available battery section 805. The adapter 800 may include a housing 15d, a first connector 700a, and a second connector 700b. The first connector 700a connects the adapter to the heater assembly section 200, while the second connector 700b connects the heater assembly section 200 to the battery section 805. The battery section can be any readily available battery section, such as the iTaste VVV3.0 battery section available from Innokin® Technology. Such a battery section can power the heater 115 until the button actuator is pressed.

[0118] Using a cylinder, heater assembly section, and adapter allows for the use of battery sections containing larger batteries, thereby extending battery life in the charging compartment.

[0119] Figure 9A and 9B This is an exploded view of the cylinder of an electronic vaporizer according to at least one example embodiment.

[0120] In at least one example embodiment, such as Figure 9A and 9B As shown, cylinder 10 and Figures 1 to 5 The inner tube 45 is identical to that in the case of the end cap 55, but is integrally formed with the end cap 55 instead of the housing 15a, and the tube includes a gasket 900 and an end insert 905 containing a plurality of outlets 910. The gasket 900, end insert 905, and outlets 910 may be identical to those described in U.S. Patent No. 9,282,772 to Tucker et al., filed March 15, 2016, the entire contents of which are incorporated herein by reference.

[0121] Figure 10A , 10B 10C and 10D are descriptions of the heating components of an electronic vaporizer according to at least one example embodiment.

[0122] In at least one example embodiment, heater assembly segment 200 and Figure 1 , 6 Similar to 8, but heater assembly section 200 includes two plate heaters 115 and a support ring 123. The support ring 123 surrounds at least a portion of the support member 120.

[0123] In at least one example embodiment, the support ring 123 is formed of PEEK or polyethylene terephthalate (PETG).

[0124] In at least one example embodiment, such as Figure 10AAs shown, the cylinder 200 includes a housing 15b, which is shown as transparent for illustrative purposes only. A heater support 120 supports two heater plates 115. A support ring 123 surrounds at least a portion of the support 120. Two leads 125a and 125b extend from each heater plate 115. The leads 125a and 125b are located between the support 120 and the ring 123. One lead 125a from each heater 115 contacts a conductive post 715 of the battery, while a second lead 125b from each heater 115 contacts a conductive connector body 705.

[0125] In at least one example embodiment, such as Figure 10B As shown, the insulating shell 710 insulates the connector body 705 from the conductive post 715.

[0126] In at least one example embodiment, the first plate heater is arranged at an angle of about 25 degrees to about 65 degrees with respect to the second plate heater. For example, the first plate heater may be arranged at an angle of about 45 degrees with respect to the second plate heater.

[0127] In at least one example embodiment, each plate heater has a length from about 2.0 mm to about 64.0 mm, a width from about 1.0 mm to about 4.0 mm, and a thickness from about 0.1 mm to about 1.0 mm.

[0128] Two plate heaters 115 are electrically connected in parallel or in series. As mentioned above, when connected in parallel, the total starting resistance can be about 0.86 ohms, while when connected in series, the total starting resistance increases so that a lower starting current is required for heater operation.

[0129] In at least one example embodiment, such as Figure 10C As shown, the support 120 has a generally wedge-shaped shape. The wedge shape is formed by a first surface 1000 and a second surface 1005. The first surface 1000 supports a first plate heater, and the second surface supports a second plate heater, as shown. Figure 10D As shown below, the first surface 1000 may be angled relative to the second surface 1005 at the same angle as the desired angle from the first heater to the second heater.

[0130] In at least one example embodiment, the heater support 120 includes a base 1010 defining an air passage 1020 therethrough. The air passage 1020 extends between a first surface 1000 and a second surface 1005. Therefore, air can pass through at least one air inlet 300 (as described above relative to...). Figure 6 (as described), and flows toward heater 115 through air passage 1020 in support 120.

[0131] In at least one example embodiment, the base 1010 includes a side wall 1020.

[0132] In at least one example embodiment, a plurality of holes 1030 may be defined through the base 1010. Leads 125a, 125b from the heater 115 extend through the holes 1030 in the base 1010 and extend to the connector 700.

[0133] In at least one example embodiment, such as Figure 10D As shown, the angle of heater 115 is such that when cylinder 10 engages with heater assembly section 200, heater 115 is pressed into the central portion of core 85. Therefore, the contact between heater 115 and core 85 is enhanced to increase steam quality.

[0134] Figure 11A and 11B This is a description of the heating component of an electronic vaporizer according to at least one example embodiment.

[0135] In at least one example embodiment, such as Figure 11A As shown, heater 115 and Figure 7 The leads 125a and 125b are the same as those in the support 120, but they are on the same side of the heater 115. Therefore, the heater 115 is cantilevered above the opening in the support 120. Since part of the heater 115 is supported by the support 120, the heater 115 does not bend when positioned to contact the core 85. Furthermore, the heater 115 is hottest at its end extending above the channel 600 in the support 120.

[0136] In embodiments that include two or more heaters 115, the heaters 115 may be larger than the heaters 115.

[0137] Figure 12 This is a description of a heating assembly based on at least one example embodiment.

[0138] In at least one example embodiment, such as Figure 12 As shown, heater 115 and Figure 11A and 11B The same as that in the heater 115, but including a third lead 125c. The three leads 125a, 125b, and 125c extend from the same side of the heater 115, but may extend from different sides.

[0139] Figure 13A and 13B This is a description of a heating assembly based on at least one example embodiment.

[0140] In at least one example embodiment, such as Figure 13A and 13BAs shown, at least one plate heater 115 may not include electrical leads but may be attached to a metal sheet 1300, may contact the conductive portion of a connector, or both. Heat is transferred to the metal sheet and then to the heater, both of which may generate steam during heating. In this embodiment, different portions of the heater 115 may contact the conductive post 715 and the conductive connector body 705, which is electrically insulated from the conductive post 715, thereby allowing power / current to flow directly to the heater 115.

[0141] In at least one example embodiment, such as Figure 14 As shown, the plate heater 115 includes four electrical leads 125a, 125b, 125c, and 125d. Two electrical leads may extend from one side of the plate heater 115, while the other two electrical leads extend from the other side of the plate heater 115.

[0142] In other example embodiments, electrical leads 125a, 125b, 125c, and 125d may all extend from the same side of the plate heater 115, one lead may extend from each side of the plate heater, or three leads may extend from one side of the plate heater 115 and one lead may extend from the other side (not shown).

[0143] At least one example embodiment relates to a method for cleaning a plate heater of an electronic vaporizer.

[0144] In at least one example embodiment, a method for cleaning a plate heater of an electronic vaping device includes removing at least one plate heater from contact with at least one core of the electronic device, and heating the at least one plate heater to a temperature of about 350 degrees Celsius. Heating burns away any residue on the heater, thus cleaning it.

[0145] In at least one example embodiment, at least one plate heater is heated for about 10 seconds to about 60 seconds. In at least one example embodiment, at least one plate heater is heated for about 30 seconds.

[0146] Because the cylinder 10 is separated from the heater assembly section, the reservoir of the e-vaping device 5 can be larger than that in commercially available e-vaping devices, thereby allowing for the storage of a larger amount of pre-prepared vapor in the e-vaping device 5. Furthermore, the heater 115 is reusable, and only the cylinder 10 can be disposable, in order to reduce at least one of waste and cost.

[0147] While many exemplary embodiments have been disclosed herein, it should be understood that other variations may be possible. Such variations should not be considered as departing from the scope of this disclosure, and all such modifications that will be apparent to those skilled in the art are intended to be included within the scope of the appended claims.
