DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] 1 is a simplified schematic diagram of a first non-combustion aerosol delivery device 100. The first non-combustion aerosol delivery device 100 comprises a housing 101 that houses various components of the first non-combustion aerosol delivery device 100.

[0024] The first non-combustible aerosol delivery device 100 comprises a first chamber 102a configured to receive a first consumable (not shown in FIG. 1 ) having a first size, and a second chamber 102b separate from the first chamber 102 and configured to receive a second consumable having a second size different from the first size. The first and second consumables each include an aerosol-generating material.

[0025] It should be noted that in this specification, references to consumables of different sizes refer to consumables that are intended to be different sizes from one another, and not to consumables that are, for example, the same size but differ in size by any small amount due to, for example, manufacturing tolerances.

[0026] The different sizes of consumables may be different types of consumables.

[0027] In some examples, the first chamber 102a and the second chamber 102b each include a respective longitudinal axis (L1, L2) that is substantially parallel to one another.

[0028] An aerosol-generating material is a material capable of generating an aerosol when, for example, heated, illuminated with light, or activated in any other way. The aerosol-generating material may or may not contain active and / or flavoring substances and may be in the form of, for example, a solid, liquid, or gel. In some embodiments, the aerosol-generating material may comprise an "amorphous solid," which may alternatively be referred to as a "monolithic solid" (i.e., non-fibrous). In some embodiments, the amorphous solid may be a dry gel. An amorphous solid is a solid material that may retain any fluid therein, such as a liquid. In some embodiments, the aerosol-generating material may comprise, for example, about 50 wt%, 60 wt%, or 70 wt% amorphous solid, up to about 90 wt%, 95 wt%, or 100 wt% amorphous solid.

[0029] The aerosol-forming materials may include one or more active agents and / or flavoring agents, one or more aerosol former materials, and optionally one or more other functional materials.

[0030] An active substance as used herein may be a physiologically active material, which is a material intended to achieve or enhance a physiological response. An active substance may be selected from, for example, dietary supplements, nootropics, psychoactive agents. An active substance may be naturally occurring or artificially obtained. An active substance may include, for example, nicotine, caffeine, taurine, theine, vitamins such as B6 or B12 or C, melatonin, cannabinoids or constituents, derivatives or combinations thereof. An active substance may include one or more constituents, derivatives or extracts of tobacco, cannabis or another plant.

[0031] In some embodiments, the active agent comprises nicotine, hi some embodiments, the active agent comprises caffeine, melatonin, or vitamin B12.

[0032] The aerosol former material may include one or more components capable of forming an aerosol. In some embodiments, the aerosol former material may include one or more of glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3-butylene glycol, erythritol, meso-erythritol, ethyl vanillate, ethyl laurate, diethyl suberate, triethyl citrate, triacetin, diacetin mixture, benzyl benzoate, benzyl phenyl acetate, tributyrin, lauryl acetate, lauric acid, myristic acid, and propylene carbonate.

[0033] The one or more other functional materials may include one or more of a pH adjuster, a colorant, a preservative, a binder, a filler, a stabilizer, and / or an antioxidant.

[0034] A first consumable and a second consumable (not shown) are intended to be inserted, one at a time, into first non-combustible aerosol delivery device 100. When the first consumable is inserted into first non-combustible aerosol delivery device 100, the first consumable is inserted into first chamber 102a, and when the second consumable is inserted into first non-combustible aerosol delivery device 100, the second consumable is inserted into second chamber 102b.

[0035] First non-combustible aerosol delivery device 100 is intended to generate an aerosol from an aerosol-generating material, whether a first consumable item or a second consumable item is inserted into first non-combustible aerosol delivery device 100. First non-combustible aerosol delivery device 100 will hereafter be referred to as device 100.

[0036] The device 100 includes an aerosol generator system 104a, 104b for generating an aerosol from an aerosol-generating material, whether a first consumable or a second consumable is inserted into the first non-combustible aerosol delivery device 100.

[0037] In one example, the aerosol generator system 104a, 104b comprises a first aerosol generator 104a for generating an aerosol from a first consumable when the first consumable is received in the first chamber 102a, and a second aerosol generator 104 for generating an aerosol from a second consumable when the second consumable is received in the second chamber 102b.

[0038] An aerosol generator is a device configured to generate an aerosol from an aerosol-generating material. In some embodiments, the or each aerosol generator is a heater configured to subject the aerosol-generating material to thermal energy to release one or more volatile substances from the aerosol-generating material to form an aerosol. In some embodiments, the or each aerosol generator is configured to generate an aerosol from the aerosol-generating material without heating. For example, the aerosol generator may be configured to subject the aerosol-generating material to one or more of vibration, increased pressure, or electrostatic energy.

[0039] Thus, in some examples, the first aerosol generator 104a is a first heating arrangement 104a configured to provide energy to heat an aerosol-generating material in a first consumable received in the first chamber 102a, and the second aerosol generator includes a second heating arrangement 104b configured to provide energy to heat an aerosol-generating material in a second consumable received in the second chamber 102b. In these examples, the first chamber 102a and the second chamber 102b are heating chambers.

[0040] In some examples, the first aerosol generator 104a and the second aerosol generator 104b each include one or more resistive heating elements arranged in thermal contact with the respective first chamber 102a and second chamber 102b. The flow of electrical current against the electrical resistance of the one or more resistive heating elements generates heat. This process is called Joule heating, ohmic heating, or resistive heating.

[0041] In some examples, each of the first aerosol generator 104a and the second aerosol generator 104b is an inductive heating arrangement and is configured to generate a varying magnetic field to inductively heat a susceptor. The inductive heating arrangement may include one or more inductors through which an alternating current is passed to generate the varying magnetic field. In some examples, each of the first aerosol generator 104a and the second aerosol generator 104b includes one or more susceptors. In other examples, each of the first aerosol generator 104a and the second aerosol generator 104b does not include a susceptor, and one or more susceptors may instead be provided as part of / with a consumable intended for use with the device 100.

[0042] The susceptor is a material that can be heated by penetration with a varying magnetic field, such as an alternating magnetic field. The susceptor may be an electrically conductive material, such that penetration with a varying magnetic field causes inductive heating of the heating material. The heating material may be a magnetic material, such that penetration with a varying magnetic field causes magnetic hysteresis heating of the heating material. The susceptor may be both electrically conductive and magnetic, such that the susceptor is heatable by both heating mechanisms. A device configured to generate a varying magnetic field is referred to herein as a magnetic field generator.

[0043] The device 100 includes a power source 106. The power source 106 provides power to various components of the device 100. In some examples, the power source 106 is a battery. In some examples, the power source 106 includes a battery and a DC-DC converter, and power is provided from the battery through the DC-DC converter. The DC-DC converter may allow the power source 106 to provide power at a different voltage to the voltage of the battery. In some examples, the device 100 may include a DC to AC converter to convert DC current, for example from the battery, to AC current to provide power to one or more inductors of the first heating component 104a and the second heating component 104b, in which case these heating components are inductive heating components. In the following examples, the power source 106 is simply referred to as the battery 106.

[0044] In the example of Figure 1, the device 100 includes control circuitry 108 configured to control various aspects of the operation of the device 100, including the aerosol generator systems 104a, 104b. In this example, the control circuitry 108 is a control processor 108 in data communication with a computer-readable memory 110. The control circuitry 108 controls various operations of the device, for example, by executing instructions stored in the computer-readable memory 110. For example, the control circuitry 108 may control the delivery of power from the battery 106 to the first aerosol generator 104a and the second aerosol generator 104b by controlling various electrical components, such as switches (not shown in Figure 1).

[0045] Device 100 further includes a user input device 109 electrically connected to control circuitry 108 and by means of which a user can operate device 100. Examples of suitable user input devices 109 include one or more buttons, a trackpad, and a touch screen, although any suitable device may be used.

[0046] In some examples, the control circuitry 108 controls the aerosol generator systems 104a and 104b such that only one of the first aerosol generator 104a and the second aerosol generator 104b is operable at any given time. In some examples, the control circuitry 108 selects which of the first aerosol generator 104a and the second aerosol generator 104b is operable in response to a user input signal received from a user input device 109. In other examples, the control circuitry 108 selects which of the first aerosol generator 104a and the second aerosol generator 104b is operable in response to a signal received from a sensor (not shown) that senses whether a consumable is inserted into the first chamber 102a or the second chamber 102b.

[0047] In the example of FIG. 1, the device 100 includes a holding device 112. The holding device 112 is configured to hold in place one consumable intended for use with the device 100 at a time. For example, the holding device 112 holds in place a first consumable received in the first chamber 102a or a second consumable received in the second chamber 102b. The holding device 112 may include any suitable holding structure, such as a clamping structure. In some examples, the holding device 112 includes a first holding structure (not shown) for holding the first consumable in the first chamber 102a and a separate second holding structure (not shown) for holding the second consumable in the second chamber 102b.

[0048] It should be understood that device 100 may include other components not shown in FIG. 1, such as ventilation inlets / outlets, charging ports, etc. It should be noted that FIG. 1 is merely a schematic sketch illustrating some components that may be included in device 100. FIG. 1 is not intended to convey the specific locations of the various components. For example, retention device 112 may be provided in any location within / on device 100, so long as it functions to hold the consumable received in chamber 102 in place.

[0049] 2a-5b illustrate a second non-combustion aerosol delivery device 200 according to one embodiment of the present invention. The second non-combustion aerosol delivery device 200 is hereafter referred to as the second device 200. The second device 200 may include any of the features of the first device described above with reference to FIG. 1, and discussion of these features will not be repeated here. Similar drawing references are used to represent such features already described with reference to FIG. 1.

[0050] The second device 200 includes a first end 220, often referred to as the mouth or proximal end 220, and a second end 222, sometimes referred to herein as the distal end 222. Although not shown in the drawings, the second device 200 may include an on / off button that allows a user to turn the second device 200 on and off as desired.

[0051] The second device 200 comprises a housing 101 (in the form of an outer cover) that surrounds and contains the various components of the second device 200. The housing 101 further comprises a top panel 206 at the mouth end 220 and a bottom panel 207 at the distal end 222. The top panel 206 and the bottom panel 207 may be permanently or removably fixed to the housing 101. Such a removably connection allows access to the internal components of the second device 200 for after-sales servicing and repair. In one example, the panels 206 and 207 may be constructed of a plastic material that may be created by injection molding or other techniques. Other materials such as metal and glass may be used. The housing 101 may be constructed of the same material as the panels 206 and 207 or may be constructed of a different material if desired. For example, the housing 101 may be constructed of aluminum and the panels 206 and 207 may be made of a plastic material or vice versa.

[0052] The top panel 206 includes a first opening 204 and a second opening 205 that are in a common plane in this example. In this example, the first opening 204 and the second opening 205 are on the same side of the second device 200 (i.e., the top panel 205), but in other examples, the first opening 204 may be on one side of the second device 200 (e.g., the top panel 205) and the second opening 205 may be on a different side of the second device 200 (e.g., the bottom panel 207). The first consumable 226 is insertable through the first opening 204 into the first chamber 102a and the second consumable 210 is insertable through the second opening 205 into the second chamber 102b. As with the first device 100 described with respect to FIG. 1, it is intended that only one of the first consumable 226 and the second consumable 210 be inserted into the second device 200 at any given time, depending on which of the first consumable 226 and the second consumable 210 the user selects for use in the second device 200 in a single user operation.

[0053] When one or the other of the first consumable 226 and second consumable 210 is inserted into the second device 200, a proximal end of that consumable extends out of the second device 200 for insertion into the mouth of a user.

[0054] The first consumable 226 and the second consumable 210 are dimensioned differently from one another. In this example, the first consumable 226 is shorter than the second consumable 210 and wider than the second consumable 210. In other examples, the dimensions of the first consumable 226 and the second consumable 210 may differ in other ways.

[0055] The second device 200 comprises an aerosol generator system (not illustrated in Figures 2a-5b) similar to the aerosol generator systems 104a, 104b of the first device 100 described above with respect to Figure 1. In the particular example of the second device 200 illustrated in Figures 2a-5b, the aerosol generator system comprises a first aerosol generator 104a for generating an aerosol from a first consumable when the first consumable is received in the first chamber 102a, and a second aerosol generator 104b for generating an aerosol from a second consumable when the second consumable is received in the second chamber 102b.

[0056] In this example, each of the first aerosol generator 104a and the second aerosol generator 104b is equipped with a respective heater, and therefore each of the first chamber 102a and the second chamber 102b is a heating chamber, and will be referred to as such hereinafter.

[0057] In this example, each of the first heating chamber 102a and the second heating chamber 102b are cylindrical heating chambers that are housed together within a single insulating sheath 224. The insulating sheath 224 may take any suitable form or include any suitable material, but in this example, the insulating sheath is a steel vacuum insulating sheath.

[0058] In this example, the second device 200, the first heating chamber 102a and the second heating chamber 102b have respective longitudinal axes that are substantially parallel to one another.

[0059] The first heating chamber 102a has a diameter 216 (as best shown in FIG. 5b) and a length 218 (as best shown in FIG. 4b), and the second heating chamber 102b has a diameter 220 (as best shown in FIG. 5b) and a length 222 (as best shown in FIG. 4a). Thus, the first heating chamber 102a and the second heating chamber 102b are configured to accommodate first and second consumables 226, 210 of different sizes.

[0060] In this example, the first heating chamber 102a has a length 218 that is shorter than the length 222 of the second heating chamber 102b. Additionally, the first heating chamber 102a has a diameter 216 that is larger than the diameter 220 of the second heating chamber 102b. As discussed above, a user may select whether they wish to use the first consumable item 226 or the second consumable item 210 and insert that consumable into the appropriate one of the first heating chamber 102a or the second heating chamber 102b.

[0061] In this example, the first heating chamber 102a includes a first hollow tube 214 for receiving a first consumable 226, and the second heating chamber 102b includes a second hollow tube 215 for receiving a second consumable 210. The first hollow tube 214 and the second hollow tube 215 each include a thermally conductive material, such as a metal, for example steel.

[0062] The short length of the first heating chamber 104a is achieved by disposing a raised platform 240 at the distal end of the first hollow tube 214. When the first consumable 226 is received in the first hollow tube, the distal end of the first consumable 226 abuts against the raised platform 240.

[0063] In contrast, when the second consumable 210 is received in the second hollow tube 215, the distal end of the second consumable 210 abuts against the inner surface of the rear panel 242 of the housing 101. The height of the raised platform 240 may be selected such that the mouths or proximal ends of the first consumable 226 and the second consumable 210 extend the same distance from the housing 101.

[0064] In this example, the first heating element 104a and the second heating element 104b each comprise a respective flexible heating foil. The first flexible heating foil 104a is wrapped around the outer surface of the first tube 214, and similarly, the second flexible heating foil 104b is wrapped around the outer surface of the first tube 215. The first flexible heating foil 104a and the second flexible heating foil 104b are each electrically connected to a power source (not shown in FIGS. 2a-5b) via control circuitry (not shown in FIGS. 2a-5b) contained in the housing 101 for a user to control the operation of the first heating element 104a and the second heating element 104b by means of a user input device (not shown in FIGS. 2a-5b).

[0065] The device 200 further comprises a lid 208 that is movable relative to the top panel 206 to close the first opening 204 and the second opening 205 when a consumable is not inserted. In Fig. 2a, the lid 208 is shown in an open configuration and in Fig. 2b, in a closed configuration. For example, a user may slide the cap 208 in the direction of arrow "A" to open the first opening 204 and the second opening 205.

[0066] The above embodiments should be understood as illustrative examples of the present invention. Further embodiments of the present invention are contemplated. For example, a third heating chamber having a third length and dimension may be included. Alternatively, non-cylindrical heating chambers or heating products may be contemplated. It is understood that any feature described in connection with any one embodiment may be used alone or in combination with other features described, in combination with one or more features of any other of the embodiments, or in any combination of any other of the embodiments. Moreover, equivalents and modifications not described above may also be utilized without departing from the scope of the present invention as defined in the appended claims.
