- This may be filled during manufacture, for example through a filling hole which is then sealed, or by other means.
- the specific nature of the aerosolizable material for example in terms of its composition, is not of primary significance to the principles described herein, and in general any conventional aerosolizable material of the type normally used in electronic cigarettes may be used.
- the present disclosure may refer to a liquid as the aerosolizable material, which as mentioned above may be a conventional e-liquid.

- the ends of the aerosolizable material transport element extend into the second region of the reservoir from which they draw aerosolizable material through the openings in the air channel to the vaporizer 40 for subsequent vaporization.
- the cartridge 2 is coupled to the control unit 4 and the control unit activated to supply power to the cartridge via the contact electrodes 46 in the end cap 48 . Power then passes through the connection leads 41 to the vaporizer 40 .
- the vaporizer is thus electrically heated and so vaporizes a portion of the aerosolizable material from the aerosolizable material transport element in the vicinity of the vaporizer. This generates aerosol in the aerosol generation region of the air path. Aerosolizable material that is vaporized from the aerosolizable material transport element is replaced by more aerosolizable material drawn from the reservoir by capillary action. While the vaporizer is activated, a user inhales on the mouthpiece end 52 of the cartridge.

- the second criterion comprises a determination being made that an amount of aerosol generating material comprises less than a predetermined amount.
- the aforementioned user interface portion may be configured to indicate the remaining amount of aerosol generating material once the predetermined amount has been reached, or alternatively indicate that the predetermined amount has been reached without also indicating the precise amount of remaining aerosol generating material.
- the amount of aerosol generating material remaining in the aerosol, provision system may be measured in a number of different ways.
- an optical sensor in the reservoir 31 may be configured to detect the remaining amount of aerosol generating material by sensing the distance to the surface of the aerosol generating material contained in the reservoir 31 .

- the second criterion comprises a determination being made that an aerosol generator from the aerosol provision system has not been operated for generating an aerosol for a period of time which exceeds a predetermined period of time.
- This may be advantageous as an optional feedback to remind the user to operate the aerosol provision system in the interest of avoiding inefficient use of the power source 16 in idle periods.
- the feedback provision system may be configured to turn off the power source upon determining that a second predetermined period of time has passed since the aerosol provision system was used to generate aerosol, the second predetermined period of time being greater than the first predetermined period of time.

Abstract
A feedback portion for a feedback provision system including an aerosol provision system. The feedback portion provides a first feedback and second feedback to a user of the aerosol provision system. The feedback provision system is configured to not allow the first feedback to be selectively prevented from being provided by the feedback portion; and is configured to allow the second feedback to be selectively prevented from being provided by the feedback portion. In this way, feedback relating, for example, to critical operating mechanisms of the aerosol provision system may be displayed in a mandatory manner in order to ensure safe operation of the aerosol provision system. On the other hand, feedback relating, for example, to useful but not critical information may be selectively provided by the feedback portion, such that the user has the option to decide whether this non-mandatory feedback is provided by the feedback portion.
Description
- This application is a continuation of Application No. 17/644,710 filed Dec. 16, 2021, which is hereby fully incorporated herein by reference.
- The present disclosure relates to aerosol provision systems such as, but not limited to, nicotine delivery systems (e.g. electronic cigarettes and the like).
- Electronic aerosol provision systems often employ an electronic cigarette (e-cigarette) or more generally an aerosol provision device. Such an aerosol provision device typically contains aerosolizable material, such as a reservoir of fluid or liquid containing a formulation, typically but not necessarily including nicotine, or a solid material such as a tobacco-based product, from which a vapor/aerosol is generated for inhalation by a user, for example through heat vaporization. Thus, an aerosol provision system will typically comprise an aerosol provision device comprising a vaporizer, e.g. a heating element, arranged to vaporize a portion of aerosolizable material to generate a vapor.
- Once a vapor has been generated, the vapor may be passed through flavoring material to add flavor to the vapor (if the aerosolizable material was not itself flavored), after which the (flavored) vapor may be then delivered to a user via a mouthpiece from the aerosol provision device.
- A potential drawback of existing aerosol provision systems and associated aerosol provision devices is that they can often provide insufficient user feedback for indicating to the user a need to take action in response to an event occurring on, or relating to/around, the aerosol provision device. This can then cause problems through the aerosol provision device then being used in ways it should not, and/or used in instances which are not as optimal as they might otherwise be.
- Various approaches are described herein which seek to help address or mitigate some of the issues discussed above.
- According to a first aspect of certain embodiments there is provided aerosol feedback provision system comprising an aerosol provision system for generating an aerosol, and a feedback portion for providing first feedback and second feedback to a user of the aerosol provision system, wherein the feedback provision system is configured to not allow the first feedback to be selectively prevented from being provided by the feedback portion; and is configured to allow the second feedback to be selectively prevented from being provided by the feedback portion.
- According to a second aspect of certain embodiments there is provided an aerosol provision system for generating an aerosol, wherein the aerosol provision system further comprises a feedback portion for providing first feedback and second feedback to a user of the aerosol provision system, wherein the aerosol provision system is configured to not allow the first feedback to be selectively prevented from being provided by the feedback portion; and is configured to allow the second feedback to be selectively prevented from being provided by the feedback portion.
- According to a third aspect of certain embodiments there is provided an aerosol provision device, for use in an aerosol provision system for generating an aerosol comprising the aerosol provision device and a consumable comprising aerosol-generating material for aerosolizing, wherein the aerosol provision device comprises: a feedback portion for providing first feedback and second feedback to a user of the aerosol provision system, wherein the aerosol provision device is configured to not allow the first feedback to be selectively prevented from being provided by the feedback portion; and is configured to allow the second feedback to be selectively prevented from being provided by the feedback portion.
- According to a fourth aspect of certain embodiments there is provided a method of controlling the provision of feedback in a feedback aerosol provision system comprising an aerosol provision system for generating an aerosol, wherein the method comprises: providing a feedback portion for providing first feedback and second feedback to a user of the aerosol provision system; not allowing the first feedback to be selectively prevented from being provided by the feedback portion; and allowing the second feedback to be selectively prevented from being provided by the feedback portion.

- The present disclosure relates to non-combustible aerosol provision devices (such as an e-cigarette) which are used as part of a wider aerosol provision system. According to the present disclosure, a “non-combustible” aerosol provision device is one where a constituent aerosolizable material of the aerosol provision device (or component thereof) is not combusted or burned in order to facilitate delivery to a user. Aerosolizable material, which also may be referred to herein as aerosol generating material or aerosol precursor material, is material that is capable of generating aerosol, for example when heated, irradiated or energized in any other way. The aerosolizable material may also be flavored, in some embodiments.
- Throughout the following description the term “e-cigarette” or “electronic cigarette” may sometimes be used, but it will be appreciated this term may be used interchangeably with an aerosol provision device. An electronic cigarette may also known as a vaping device or electronic nicotine delivery system (END), although it is noted that the presence of nicotine in the aerosolizable material is not a requirement.
- In some embodiments, the aerosol provision device is a hybrid device configured to generate aerosol using a combination of aerosolizable materials, one or a plurality of which may be heated. In some embodiments, the hybrid device comprises a liquid or gel aerosolizable material and a solid aerosolizable material. The solid aerosolizable material may comprise, for example, tobacco or a non-tobacco product.
- Typically, the (non-combustible) aerosol provision system may comprise a cartridge/consumable part and a body/ aerosol provision device/reusable part, which is configured to releasably engage with the cartridge/consumable part.
- The aerosol provision device may be provided with a means for powering a vaporizer (aerosol generator) therein, and there may be provided an aerosolizable material transport element for receiving the aerosolizable material that is to be vaporized. The aerosol provision device may also be provided with a reservoir for containing aerosolizable material, and in some embodiments a further reservoir for containing flavoring material for flavoring a generated vapor from the aerosol provision device.
- In some embodiments, the vaporizer may be a heater/heating element capable of interacting with the aerosolizable material (also called aerosol generating material) so as to release one or more volatiles from the aerosolizable material to form a vapor/aerosol. In some embodiments, the vaporizer is capable of generating an aerosol from the aerosolizable material without heating. For example, the vaporizer may be capable of generating a vapor/aerosol from the aerosolizable material without applying heat thereto, for example via one or more of vibrational, mechanical, pressurization or electrostatic means.
- In some embodiments, the substance to be delivered may be an aerosolizable material which may comprise an active constituent, a carrier constituent and optionally one or more other functional constituents.
- The active constituent may comprise one or more physiologically and/or olfactory active constituents which are included in the aerosolizable material in order to achieve a physiological and/or olfactory response in the user. The active constituent may for example be selected from nutraceuticals, nootropics, and psychoactives. The active constituent may be naturally occurring or synthetically obtained. The active constituent may comprise for example nicotine, caffeine, taurine, theine, a vitamin such as B6 or
B 12 or C, melatonin, a cannabinoid, or a constituent, derivative, or combinations thereof. The active constituent may comprise a constituent, derivative or extract of tobacco or of another botanical. In some embodiments, the active constituent is a physiologically active constituent and may be selected from nicotine, nicotine salts (e.g. nicotine ditartrate/nicotine bitartrate), nicotine-free tobacco substitutes, other alkaloids such as caffeine, or mixtures thereof. - In some embodiments, the active constituent is an olfactory active constituent and may be selected from a “flavor” and/or “flavorant” which, where local regulations permit, may be used to create a desired taste, aroma or other somatosensorial sensation in a product for adult consumers. In some instances such constituents may be referred to as flavors, flavorants, flavoring material, cooling agents, heating agents, and/or sweetening agents. They may include naturally occurring flavor materials, botanicals, extracts of botanicals, synthetically obtained materials, or combinations thereof (e.g., tobacco, cannabis, licorice (liquorice), hydrangea, eugenol, Japanese white bark magnolia leaf, chamomile, fenugreek, clove, maple, matcha, menthol, Japanese mint, aniseed (anise), cinnamon, turmeric, Indian spices, Asian spices, herb, wintergreen, cherry, berry, red berry, cranberry, peach, apple, orange, mango, clementine, lemon, lime, tropical fruit, papaya, rhubarb, grape, durian, dragon fruit, cucumber, blueberry, mulberry, citrus fruits, Drambuie, bourbon, scotch, whiskey, gin, tequila, rum, spearmint, peppermint, lavender, aloe vera, cardamom, celery, cascarilla, nutmeg, sandalwood, bergamot, geranium, khat, naswar, betel, shisha, pine, honey essence, rose oil, vanilla, lemon oil, orange oil, orange blossom, cherry blossom, cassia, caraway, cognac, jasmine, ylang-ylang, sage, fennel, wasabi, piment, ginger, coriander, coffee, hemp, a mint oil from any species of the genus Mentha, eucalyptus, star anise, cocoa, lemongrass, rooibos, flax, ginkgo biloba, hazel, hibiscus, laurel, mate, orange skin, rose, tea such as green tea or black tea, thyme, juniper, elderflower, basil, bay leaves, cumin, oregano, paprika, rosemary, saffron, lemon peel, mint, beefsteak plant, curcuma, cilantro, myrtle, cassis, valerian, pimento, mace, damien, marjoram, olive, lemon balm, lemon basil, chive, carvi, verbena, tarragon, limonene, thymol, camphene), flavor enhancers, bitterness receptor site blockers, sensorial receptor site activators or stimulators, sugars and/or sugar substitutes (e.g., sucralose, acesulfame potassium, aspartame, saccharine, cyclamates, lactose, sucrose, glucose, fructose, sorbitol, or mannitol), and other additives such as charcoal, chlorophyll, minerals, botanicals, or breath freshening agents. They may be imitation, synthetic or natural ingredients or blends thereof. They may be in any suitable form, for example, liquid such as an oil, solid such as a powder, or gasone or more of extracts (e.g., licorice, hydrangea, Japanese white bark magnolia leaf, chamomile, fenugreek, clove, menthol, Japanese mint, aniseed, cinnamon, herb, wintergreen, cherry, berry, peach, apple, Drambuie, bourbon, scotch, whiskey, spearmint, peppermint, lavender, cardamom, celery, cascarilla, nutmeg, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, cassia, caraway, cognac, jasmine, ylang-ylang, sage, fennel, piment, ginger, anise, coriander, coffee, or a mint oil from any species of the genus Mentha), flavor enhancers, bitterness receptor site blockers, sensorial receptor site activators or stimulators, sugars and/or sugar substitutes (e.g., sucralose, acesulfame potassium, aspartame, saccharine, cyclamates, lactose, sucrose, glucose, fructose, sorbitol, or mannitol), and other additives such as charcoal, chlorophyll, minerals, botanicals, or breath freshening agents. They may be imitation, synthetic or natural ingredients or blends thereof. They may be in any suitable form, for example, oil, liquid, or powder.
- In some embodiments, the flavoring material (flavor) may comprise menthol, spearmint and/or peppermint. In some embodiments, the flavor comprises flavor components of cucumber, blueberry, citrus fruits and/or redberry. In some embodiments, the flavor comprises eugenol. In some embodiments, the flavor comprises flavor components extracted from tobacco. In some embodiments, the flavor may comprise a sensate, which is intended to achieve a somatosensorial sensation which are usually chemically induced and perceived by the stimulation of the fifth cranial nerve (trigeminal nerve), in addition to or in place of aroma or taste nerves, and these may include agents providing heating, cooling, tingling, numbing effect. A suitable heat effect agent may be, but is not limited to, vanillyl ethyl ether and a suitable cooling agent may be, but not limited to eucalyptol, WS-3.
- The carrier constituent may comprise one or more constituents capable of forming an aerosol. In some embodiments, the carrier constituent may comprise one or more of glycerine, glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3-butylene glycol, erythritol, meso-Erythritol, ethyl vanillate, ethyl laurate, a diethyl suberate, triethyl citrate, triacetin, a diacetin mixture, benzyl benzoate, benzyl phenyl acetate, tributyrin, lauryl acetate, lauric acid, myristic acid, and propylene carbonate.
- The one or more other functional constituents may comprise one or more of pH regulators, coloring agents, preservatives, binders, fillers, stabilizers, and/or antioxidants.
- As noted above, aerosol provision devices (e-cigarettes) may often comprise a modular assembly including both a reusable part (body) and a replaceable consumable (cartridge) part. Devices conforming to this type of two-part modular configuration may generally be referred to as two-part devices. It is also common for electronic cigarettes to have a generally elongate shape. For the sake of providing a concrete example, certain embodiments of the disclosure described herein may comprise this kind of generally elongate two-part device employing consumable parts. However, it will be appreciated the underlying principles described herein may equally be adopted for other electronic cigarette configurations, for example modular devices comprising more than two parts, as devices conforming to other overall shapes, for example based on so-called box-mod high performance devices that typically have a more boxy shape.
- From the forgoing therefore, and with reference to
FIG. 1 is a schematic perspective view of an example aerosol provision system / device (e-cigarette) 1 in accordance with certain embodiments of the disclosure. Terms concerning the relative location of various aspects of the electronic cigarette (e.g. terms such as upper, lower, above, below, top, bottom etc.) are used herein with reference to the orientation of the electronic cigarette as shown inFIG. 1 (unless the context indicates otherwise). However, it will be appreciated this is purely for ease of explanation and is not intended to indicate there is any required orientation for the electronic cigarette in use. - The
e-cigarette 1 comprises two main components, namely acartridge 2 and acontrol unit 4. Thecontrol unit 4 and thecartridge 2 are shown separated inFIG. 1 , but are coupled together when in use. - The
cartridge 2 andcontrol unit 4 are coupled by establishing a mechanical and electrical connection between them. The specific manner in which the mechanical and electrical connection is established is not of primary significance to the principles described herein and may be established in accordance with conventional techniques, for example based around a screw thread, bayonet, latched or friction-fit mechanical fixing with appropriately arranged electrical contacts/electrodes for establishing the electrical connection between the two parts as appropriate. For exampleelectronic cigarette 1 represented inFIG. 1 , the cartridge comprises amouthpiece end 52 and aninterface end 54 and is coupled to the control unit by inserting aninterface end portion 6 at the interface end of the cartridge into acorresponding receptacle 8/receiving section of the control unit. Theinterface end portion 6 of the cartridge is a close fit to bereceptacle 8 and includesprotrusions 56 which engage with corresponding detents in the interior surface of areceptacle wall 12 defining thereceptacle 8 to provide a releasable mechanical engagement between the cartridge and the control unit. An electrical connection is established between the control unit and the cartridge via a pair of electrical contacts on the bottom of the cartridge (not shown inFIG. 1 ) and corresponding sprung contact pins in the base of the receptacle 8 (not shown inFIG. 1 ). As noted above, the specific manner in which the electrical connection is established is not significant to the principles described herein, and indeed some implementations might not have an electrical connection between the cartridge and a control unit at all, for example because the transfer of electrical power from the reusable part to the cartridge may be wireless (e.g. based on electromagnetic induction techniques). With respect to such embodiments, for instance, theaerosol provision device 4 and/or thereceptacle 8 may comprise a coil which is configured to inductively heat a susceptor located in the consumable/cartridge, wherein the susceptor is configured to heat the aerosol generating material in the consumable/cartridge to generate the aerosol. In this way, the aerosol generator may comprise the susceptor. - The electronic cigarette 1 (aerosol provision device) has a generally elongate shape extending along a longitudinal axis L. When the cartridge is coupled to the control unit, the overall length of the electronic cigarette in this example (along the longitudinal axis) is around 12.5 cm. The overall length of the control unit is around 9 cm and the overall length of the cartridge is around 5 cm (i.e. there is around 1.5 cm of overlap between the
interface end portion 6 of the cartridge and thereceptacle 8 of the control unit when they are coupled together). The electronic cigarette has a cross-section which is generally oval and which is largest around the middle of the electronic cigarette and tapers in a curved manner towards the ends. The cross-section around the middle of the electronic cigarette has a width of around 2.5 cm and a thickness of around 1.7 cm. The end of the cartridge has a width of around 2 cm and a thickness of around 0.6 mm, whereas the other end of the electronic cigarette has a width of around 2 cm and a thickness of around 1.2 cm. The outer housing of the electronic cigarette is in this example is formed from plastic. It will be appreciated the specific size and shape of the electronic cigarette and the material from which it is made is not of primary significance to the principles described herein and may be different in different implementations. That is to say, the principles described herein may equally be adopted for electronic cigarettes having different sizes, shapes and/or materials. - The
control unit 4 may in accordance with certain embodiments of the disclosure be broadly conventional in terms of its functionality and general construction techniques. In the example ofFIG. 1 , thecontrol unit 4 comprises a plasticouter housing 10 including thereceptacle wall 12 that defines thereceptacle 8 for receiving the end of the cartridge as noted above. Theouter housing 10 of thecontrol unit 4 in this example has a generally oval cross section conforming to the shape and size of thecartridge 2 at their interface to provide a smooth transition between the two parts. Thereceptacle 8 and theend portion 6 of thecartridge 2 are symmetric when rotated through 180° so the cartridge can be inserted into the control unit in two different orientations. Thereceptacle wall 12 includes two control unit air inlet openings 14 (i.e. holes in the wall). Theseopenings 14 are positioned to align with anair inlet 50 for the cartridge when the cartridge is coupled to the control unit. A different one of theopenings 14 aligns with theair inlet 50 of the cartridge in the different orientations. It will be appreciated some implementations may not have any degree of rotational symmetry such that the cartridge is couplable to the control unit in only one orientation while other implementations may have a higher degree of rotational symmetry such that the cartridge is couplable to the control unit in more orientations. - The control unit further comprises a
battery 16 for providing operating power for the electronic cigarette,control circuitry 18 for controlling and monitoring the operation of the electronic cigarette, auser input button 20, anindicator light 22, and a chargingport 24. - The
battery 16 in this example is rechargeable and may be of a conventional type, for example of the kind normally used in electronic cigarettes and other applications requiring provision of relatively high currents over relatively short periods. Thebattery 16 may be recharged through the chargingport 24, which may, for example, comprise a USB connector. - The
input button 20 in this example is a conventional mechanical button, for example comprising a sprung mounted component which may be pressed by a user to establish an electrical contact in underlying circuitry. In this regard, the input button may be considered an input device for detecting user input, e.g. to trigger aerosol generation, and the specific manner in which the button is implemented is not significant. For example, other forms of mechanical button or touch-sensitive button (e.g. based on capacitive or optical sensing techniques) may be used in other implementations, or there may be no button and the device may rely on a puff detector for triggering aerosol generation. - The
indicator light 22 is provided to give a user with a visual indication of various characteristics associated with the electronic cigarette, for example, an indication of an operating state (e.g. on/off/standby), and other characteristics, such as battery life or fault conditions. Different characteristics may, for example, be indicated through different colors and/or different flash sequences in accordance with generally conventional techniques. - The
control circuitry 18 is suitably configured/programmed to control the operation of the electronic cigarette to provide conventional operating functions in line with the established techniques for controlling electronic cigarettes. The control circuitry (processor circuitry) 18 may be considered to logically comprise various sub-units/circuitry elements associated with different aspects of the electronic cigarette’s operation. For example, depending on the functionality provided in different implementations, thecontrol circuitry 18 may comprises power supply control circuitry for controlling the supply of power from the battery/power supply to the cartridge in response to user input, user programming circuitry for establishing configuration settings (e.g. user-defined power settings) in response to user input, as well as other functional units/circuitry associated functionality in accordance with the principles described herein and conventional operating aspects of electronic cigarettes, such as indicator light display driving circuitry and user input detection circuitry. It will be appreciated the functionality of thecontrol circuitry 18 can be provided in various different ways, for example using one or more suitably programmed programmable computer(s) and/or one or more suitably configured application-specific integrated circuit(s)/circuitry/chip(s)/chipset(s) configured to provide the desired functionality. -
FIG. 2 is an exploded schematic perspective view of the cartridge 2 (exploded along the longitudinal axis L). Thecartridge 2 comprises ahousing part 32, anair channel seal 34, a dividingwall element 36, anoutlet tube 38, a vaporizer/heating element 40, an aerosolizablematerial transport element 42, aplug 44, and anend cap 48 withcontact electrodes 46.FIGS. 3 to 6 schematically represents some of these components in more detail. -

FIG. 4A is a schematic perspective view of the dividingwall element 36 as seen from below.FIG. 4B is a schematic cross-section through an upper part of the dividingwall element 36 as viewed from below. -
FIG. 5A is a schematic perspective view of theplug 44 from above andFIG. 5B is a schematic perspective view of theplug 44 from below.FIG. 5C is a schematic view of theplug 44 along the longitudinal axis L seen from themouthpiece end 52 of the cartridge (i.e. viewed from above for the orientation inFIGS. 1 and 2 ). -
FIG. 6A is a schematic perspective view of theend cap 48 from above.FIG. 6B is a schematic view of theend cap 48 along the longitudinal axis L seen from themouthpiece end 52 of the cartridge (i.e. from above). - The
housing part 32 in this example comprises a housingouter wall 64 and a housinginner tube 62 which in this example are formed from a single molding of polypropylene. The housingouter wall 64 defines the external appearance of thecartridge 2 and the housinginner tube 62 defines a part the air channel through the cartridge. The housing part is open at theinterface end 54 of the cartridge and closed at themouthpiece end 52 of the cartridge except for a mouthpiece opening/aerosol outlet 60 in fluid communication with the housinginner tube 62. Thehousing part 32 includes an opening in a sidewall which provides theair inlet 50 for the cartridge. Theair inlet 50 in this example has an area of around 2 mm2. The outer surface of theouter wall 64 of thehousing part 32 includes theprotrusions 56 discussed above which engage with corresponding detents in the interior surface of thereceptacle wall 12 defining thereceptacle 8 to provide a releasable mechanical engagement between the cartridge and the control unit. The inner surface of theouter wall 64 of the housing part includesfurther protrusions 66 which act to provide an abutment stop for locating the dividingwall element 36 along the longitudinal axis L when the cartridge is assembled. Theouter wall 64 of thehousing part 32 further comprises holes which providelatch recesses 68 arranged to receivecorresponding latch projections 70 in the end cap to fix the end cap to be housing part when the cartridge is assembled. - The
outer wall 64 of thehousing part 32 includes a double-walled section 74 that defines agap 76 in fluid communication with theair inlet 50. Thegap 76 provides a portion of the air channel through the cartridge. In this example the doubled-walled section 74 of thehousing part 32 is arranged so the gap defines an air channel running within the housingouter wall 64 parallel to the longitudinal axis with a cross-section in a plane perpendicular to the longitudinal axis of around 3 mm2. The gap/portion ofair channel 76 defined by the double-walled section of the housing part extends down to the open end of thehousing part 32. - The
air channel seal 34 is a silicone molding generally in the form of a tube having a throughhole 80. The outer wall of theair channel seal 34 includescircumferential ridges 84 and anupper collar 82. The inner wall of theair channel seal 34 also includes circumferential ridges, but these are not visible inFIG. 2 . When the cartridge is assembled theair channel seal 34 is mounted to the housinginner tube 62 with an end of the housinginner tube 62 extending partly into the throughhole 80 of theair channel seal 34. The throughhole 80 in the air channel seal has a diameter of around 5.8 mm in its relaxed state whereas the end of the housinginner tube 62 has a diameter of around 6.2 mm so that a seal is formed when theair channel seal 34 is stretched to accommodate the housinginner tube 62. This seal is facilitated by the ridges on the inner surface of theair channel seal 34. - The
outlet tube 38 comprises a tubular section, for instance made of ANSI 304 stainless steel or polypropylene, with an internal diameter of around 8.6 mm and a wall thickness of around 0.2 mm. The bottom end of theoutlet tube 38 includes a pair of diametrically opposingslots 88 with an end of each slot having asemi-circular recess 90. When the cartridge is assembled theoutlet tube 38 mounts to the outer surface of theair channel seal 34. The outer diameter of the air channel seal is around 9.0 mm in its relaxed state so that a seal is formed when theair channel seal 34 is compressed to fit inside theoutlet tube 38. This seal is facilitated by theridges 84 on the outer surface of theair channel seal 34. Thecollar 80 on theair channel seal 34 provides a stop for theoutlet tube 38. - The aerosolizable
material transport element 42 comprises a capillary wick and thevaporizer 40 comprises a resistance wire heater wound around the capillary wick. In addition to the portion of the resistance wire wound around the capillary wick, the vaporizer compriseselectrical leads 41 which pass through holes in theplug 44 to contactelectrodes 46 mounted to theend cap 54 to allow power to be supplied to the vaporizer via the electrical interface the established when the cartridge is connected to a control unit. The vaporizer leads 41 may comprise the same material as the resistance wire wound around the capillary wick, or may comprise a different material (e.g. lower-resistance material) connected to the resistance wire wound around the capillary wick. In this example theheater coil 40 comprises a nickel iron alloy wire and thewick 42 comprises a glass fiber bundle. The vaporizer and aerosolizable material transport element may be provided in accordance with any conventional techniques and is may comprise different forms and/or different materials. For example, in some implementations the wick may comprise fibrous or solid a ceramic material and the heater may comprise a different alloy. In other examples the heater and wick may be combined, for example in the form of a porous and a resistive material. More generally, it will be appreciated the specific nature aerosolizable material transport element and vaporizer is not of primary significance to the principles described herein. - When the cartridge is assembled, the
wick 42 is received in thesemi-circular recesses 90 of theoutlet tube 38 so that a central portion of the wick about which the heating coil is would is inside the outlet tube while end portions of the wick are outside theoutlet tube 38. - The
plug 44 in this example comprises a single molding of silicone, may be resilient. The plug comprises abase part 100 with anouter wall 102 extending upwardly therefrom (i.e. towards the mouthpiece end of the cartridge). The plug further comprises aninner wall 104 extending upwardly from thebase part 100 and surrounding a throughhole 106 through thebase part 100. - The
outer wall 102 of theplug 44 conforms to an inner surface of thehousing part 32 so that when the cartridge is assembled the plug in 44 forms a seal with thehousing part 32. Theinner wall 104 of theplug 44 conforms to an inner surface of theoutlet tube 38 so that when the cartridge is assembled theplug 44 also forms a seal with theoutlet tube 38. Theinner wall 104 includes a pair of diametrically opposingslots 108 with the end of each slot having asemi-circular recess 110. Extended outwardly (i.e. in a direction away from the longitudinal axis of the cartridge) from the bottom of each slot in theinner wall 104 is acradle section 112 shaped to receive a section of the aerosolizablematerial transport element 42 when the cartridge is assembled. Theslots 108 andsemi-circular recesses 110 provided by the inner wall of theplug 44 and theslots 88 andsemi-circular recesses 90 of theoutlet tube 38 are aligned so that theslots 88 in theoutlet tube 38 accommodate respective ones of thecradles 112 with the respective semi-circular recesses in the outlet tube and plug cooperating to define holes through which the aerosolizable material transport element passes. The size of the holes provided by the semi-circular recesses through which the aerosolizable material transport element passes correspond closely to the size and shape of the aerosolizable material transport element, but are slightly smaller so a degree of compression is provided by the resilience of theplug 44. This allows aerosolizable material to be transported along the aerosolizable material transport element by capillary action while restricting the extent to which aerosolizable material which is not transported by capillary action can pass through the openings. As noted above, theplug 44 includesfurther openings 114 in thebase part 100 through which the contact leads 41 for the vaporizer pass when the cartridge is assembled. The bottom of the base part of the plug includesspacers 116 which maintain an offset between the remaining surface of the bottom of the base part and theend cap 48. Thesespacers 116 include theopenings 114 through which the electrical contact leads 41 for the vaporizer pass. - The
end cap 48 comprises a polypropylene molding with a pair of gold-plated copper electrode posts 46 mounted therein. - The ends of the electrode posts 44 on the bottom side of the end cap are close to flush with the
interface end 54 of the cartridge provided by theend cap 48. These are the parts of the electrodes to which correspondingly aligned sprung contacts in the control unit connect when the cartridge is assembled and connected to the control unit. The ends of the electrode posts on the inside of the cartridge extend away from theend cap 48 and into theholes 114 in theplug 44 through which the contact leads 41 pass. The electrode posts are slightly oversized relative to theholes 114 and include a chamfer at their upper ends to facilitate insertion into theholes 114 in the plug where they are maintained in pressed contact with the contact leads for the vaporizer by virtue of the plug. - The end cap has a
base section 124 and anupstanding wall 120 which conforms to the inner surface of thehousing part 32. Theupstanding wall 120 of theend cap 48 is inserted into thehousing part 32 so thelatch projections 70 engage with the latch recesses 68 in thehousing part 32 to snap-fit theend cap 48 to the housing part when the cartridge is assembled. The top of theupstanding wall 120 of theend cap 48 abuts a peripheral part of theplug 44 and the lower face of thespacers 116 on the plug also abut thebase section 124 of the plug so that when theend cap 48 is attached to the housing part it presses against theresilient part 44 to maintain it in slight compression. - The
base portion 124 of theend cap 48 includes aperipheral lip 126 beyond the base of theupstanding wall 112 with a thickness which corresponds with the thickness of the outer wall of the housing part at the interface end of the cartridge. The end cap also includes anupstanding locating pin 122 which aligns with acorresponding locating hole 128 in the plug to help establish their relative location during assembly. - The dividing
wall element 36 comprises a single molding of polypropylene and includes a dividingwall 130 and acollar 132 formed by projections from the dividingwall 130 in the direction towards the interface end of the cartridge. The dividingwall element 36 has acentral opening 134 through which theoutlet tube 38 passes (i.e. the dividing wall is arranged around the outlet tube 38). In some embodiments, the dividingwall element 36 may be integrally formed with theoutlet tube 38. When the cartridge is assembled, the upper surface of theouter wall 102 of theplug 44 engages with the lower surface of the dividingwall 130, and the upper surface of the dividingwall 130 in turn engages with theprojections 66 on the inner surface of theouter wall 64 of thehousing part 32. Thus, the dividingwall 130 prevents the plug from being pushed too far into the housing part 32 - i.e. the dividingwall 130 is fixedly located along the longitudinal axis of the cartridge by theprotrusions 66 in the housing part and so provides the plug with a fixed surface to push against. Thecollar 132 formed by projections from the dividing wall includes a first pair of opposing projections /tongues 134 which engage with corresponding recesses on an inner surface of theouter wall 102 of theplug 44. The protrusions from the dividingwall 130 further provide a pair ofcradle sections 136 configured to engage with corresponding ones of thecradle sections 112 in thepart 44 when the cartridge is assembled to further define the opening through which the aerosolizable material transport element passes. - When the cartridge is assembled an air channel extending from the
air inlet 50 to theaerosol outlet 60 through the cartridge is formed. Starting from theair inlet 50 in the side wall of thehousing part 32, a first section of the air channel is provided by thegap 76 formed by the double-walled section 74 in theouter wall 64 of thehousing part 32 and extends from theair inlet 50 towards theinterface end 54 of the cartridge and past theplug 44. A second portion of the air channel is provided by the gap between the base of theplug 44 and theend cap 48. A third portion of the air channel is provided by thehole 106 through theplug 44. A fourth portion of the air channel is provided by the region within theinner wall 104 of the plug and the outlet tube around thevaporizer 40. This fourth portion of the air channel may also be referred to as an aerosol/aerosol generation region, it being the primary region in which aerosol is generated during use. The air channel from theair inlet 50 to the aerosol generation region may be referred to as an air inlet section of the air channel. A fifth portion of the air channel is provided by the remainder of theoutlet tube 38. A sixth portion of the air channel is provided by the outer housinginner tube 62 which connects the air channel to theaerosol outlet 60. The air channel from the aerosol generation region to be the aerosol outlet may be referred to as an aerosol outlet section of the air channel. - Also, when the cartridge is assembled a
reservoir 31 for aerosolizable material is formed by the space outside the air channel and inside thehousing part 32. This may be filled during manufacture, for example through a filling hole which is then sealed, or by other means. The specific nature of the aerosolizable material, for example in terms of its composition, is not of primary significance to the principles described herein, and in general any conventional aerosolizable material of the type normally used in electronic cigarettes may be used. The present disclosure may refer to a liquid as the aerosolizable material, which as mentioned above may be a conventional e-liquid. However, the principles of the present disclosure apply to any aerosolizable material which has the ability to flow, and may include a liquid, a gel, or a solid, where for a solid a plurality of solid particles may be considered to have the ability to flow when considered as a bulk. - The reservoir is closed at the interface end of the cartridge by the
plug 44. The reservoir includes a first region above the dividingwall 130 and a second region below the dividingwall 130 within the space formed between the air channel and the outer wall of the plug. The aerosolizable material transport element (capillary wick) 42 passes through openings in the wall of the air channel provided by thesemi-circular recesses plug 44 and theoutlet tube 38 and thecradle sections plug 44 and the dividingwall element 36 that engage with one another as discussed above. Thus, the ends of the aerosolizable material transport element extend into the second region of the reservoir from which they draw aerosolizable material through the openings in the air channel to thevaporizer 40 for subsequent vaporization. - In normal use, the
cartridge 2 is coupled to thecontrol unit 4 and the control unit activated to supply power to the cartridge via thecontact electrodes 46 in theend cap 48. Power then passes through the connection leads 41 to thevaporizer 40. The vaporizer is thus electrically heated and so vaporizes a portion of the aerosolizable material from the aerosolizable material transport element in the vicinity of the vaporizer. This generates aerosol in the aerosol generation region of the air path. Aerosolizable material that is vaporized from the aerosolizable material transport element is replaced by more aerosolizable material drawn from the reservoir by capillary action. While the vaporizer is activated, a user inhales on themouthpiece end 52 of the cartridge. This causes air to be drawn through whichever controlunit air inlet 14 aligns with theair inlet 50 of the cartridge (which will depend on the orientation in which the cartridge was inserted into the control unit receptacle 8). Air then enters the cartridge through theair inlet 50, passes along thegap 76 in the double-walled section 74 of thehousing part 32, passes between theplug 44 and theend cap 48 before entering the aerosol generation region surrounding thevaporizer 40 through thehole 106 in thebase part 100 of theplug 44. The incoming air mixes with aerosol generated from the vaporizer to form a condensation aerosol, which is then drawn along theoutlet tube 38 and thehousing part inner 62 before exiting through the mouthpiece outlet/aerosol outlet 60 for user inhalation. - From the above
FIG. 1-6B , it can be seen a possible embodiment construction ofaerosol provision system 1 which is configured for generating an aerosol, which is suitable for use in the context of the present disclosure. - Turning now to
FIG. 7A-12 , the present disclosure also provides for a feedback provision system comprising anaerosol provision system 1 for generating an aerosol, and a feedback portion for providing first feedback and second feedback to a user of theaerosol provision system 1, wherein the feedback provision system is configured to not allow the first feedback to be selectively prevented from being provided by the feedback portion; and is configured to allow the second feedback to be selectively prevented from being provided by the feedback portion. - In this way, feedback relating, for example, to critical operating mechanisms of the aerosol provision system may be displayed in a mandatory manner in order to ensure safe operation of the aerosol provision system. On the other hand, feedback relating, for example, to useful but not critical information may be selectively provided by the feedback portion, such that the user has the option to decide whether this non-mandatory feedback is provided by the feedback portion.
- As will be described in further detail below, by allowing selective prevention of a second (not mandatory) feedback but not a first (mandatory) feedback, the feedback provision system may ensure that important first feedback is displayed regardless of the user’s preference so that the system can continue to operate safely. This may be of particular advantage when the first feedback relates to whether the device is operating within acceptable parameters, for example a temperature parameter of the aerosol provision system, such as its
aerosol generator 40 for instance. - As illustrated in
FIGS. 7A and 7B , thefeedback portion consumable 2 of the aerosol provision system, or on theaerosol provision device 4 in various embodiments. In some embodiments, more than one feedback portion may be used, such that afirst feedback portion 702 a is located on the cartridge and a second feedback portion 720 b is located on theaerosol provision device 4. - The feedback portion may take a number of different forms. For example, the feedback portion may comprise a light indicator (e.g. LED), a visual display screen (e.g. LCD, LED, etc.), an acoustic device (e.g. a speaker, buzzer, etc.), a haptic device, a thermal device, or any other suitable means of conveying information to a user. It should also be understood that the feedback portion may comprise any number and combination of feedback mechanisms needed to convey the required information.
- Furthermore, in some very particular embodiments, a specific feedback mechanism may be reserved for a specific ‘type’ of feedback. For example, an acoustic type feedback may be reserved for the first feedback described herein. In this way, when the user receives acoustic feedback, they would immediately understand that the feedback relates to the mandatory first feedback - as opposed to another type of feedback, such as haptic and/or visual type feedback, which might be instead reserved for the second, optional, feedback (and/or any third, optional, feedback). Thus, more efficient communication of feedback may be achieved in this way.
- With respect to how the feedback portion may be made to selectively prevent the second feedback from being provided to the feedback portion, the feedback provision system may comprise a
user interface portion 252; 704 a, 704 b for allowing a user of the aerosol provision system to toggle between a first mode of operation in which the second feedback is configured to be provided by the feedback portion, and a second mode of operation in which the second feedback is configured to be prevented from being provided by the feedback portion. In this way, the user is advantageously able to enable or disable optional feedback according to their desire. For example, the user may wish to check the power level of a power source of the aerosol provision system. This feedback may then be selectively enabled to toggle the device into first mode of operation, the feedback observed by the user, and then selectively disabled to toggle the device into the second mode of operation. - There may also be provided a
toggle indicator 706 a, 706 b which indicates whether the second feedback has been enabled or disabled. For example, the toggle indicator may comprise an LED indicator light, an acoustic element, a haptic element, or any other means suitable for providing an indication to the user that the second feedback is enabled or disabled. - In certain particular embodiments, the toggle indicator may be integral to the user interface portion. For example, as illustrated in
FIGS. 8A and 8B , the user interface portion may comprise a slidingswitch toggle indicator user interface portion consumable 2 or theaerosol provision device 4. It should also be noted that the sliding switch illustrated inFIGS. 8A and 8B are examples only, and that other toggle mechanisms may be used. For example, a button switch may be provided as the user interface wherein the button switch is able to be selectively moved between two positions with different heights corresponding to whether the second feedback is enabled or disabled. Non-mechanical means may equally be provided as the user interface, such as a touchpad. - Appreciably, in accordance with some embodiments, there may well be provided more than two positions for the user interface portion, such that (and put differently), the feedback provision system may be configured for allowing a user of the feedback provision system to toggle between the first mode of operation M1, the second mode of operation M2, and a third mode of operation in which third feedback is configured to be provided by the feedback portion. With respect to any such third feedback, this third feedback (like the second feedback) may be configured to be disabled, and/or to prevented from being provided by the feedback portion, by toggling the user interface portion to the second mode of operation. However, the level of the third feedback may be configured to be different from (such as more than, or less than) the level of the second feedback.
- By the ‘level’ of the feedback, this may comprise the frequency of the feedback, and/or the amount of the feedback (e.g. the brightness of the feedback in the case of visual feedback, or the loudness of the feedback in the case of acoustic feedback), the magnitude of the feedback (e.g. the brightness of the feedback in the case of visual feedback, or the strength of the feedback in the case of haptic feedback), or even the prominence of the feedback (e.g. the brightness of the feedback in the case of visual feedback, or the strength of the feedback in the case of haptic feedback, or the loudness of the feedback in the case of acoustic feedback). Appreciably as well, where such a level is employed, this could also comprise an average level, or a maximum level, in accordance with some narrower embodiments.
- It should also be appreciated that not only the level of the feedback, but also the type of the feedback that is provided in conjunction with the different modes may be different. For example, the first mode may enable feedback to be provided via a haptic element while the second mode may enable feedback to be provided via an audio element.
- From the foregoing therefore, it may be seen that there may be provided more than two modes of operation in some cases, such as there being the second mode of operation for only providing the (mandatory) first feedback, and there then being at least two other modes of operation (e.g. the first mode of operation and a third mode of operation) in which different levels of other additional (non-mandatory) feedback can also be provided.
- For completeness as well, it is to be noted that any such employed feedback portion, and/or other device for controlling the provision of the second (optional) feedback, may be located on or in the
aerosol provision system 1, such as in either a consumable 2 oraerosol provision device 4 therefrom (where such a consumable 2/aerosol provision device 4 arrangement is employed). Appreciably however, in accordance with some embodiments, any such feedback portion and/or other device for controlling the provision of the second (optional) feedback may be located in anelectrical device 250, as part of a wider feedback provision comprising theaerosol provision system 1 and theelectrical device 250, wherein theelectrical device 250 is operable to wirelessly communicate with theaerosol provision system 1, e.g. via a wireless connection protocol, such as Bluetooth. Such an embodiment is illustrated in the embodiments ofFIGS. 11 and 12 , for instance. - As to what such an
electrical device 250 might be, it is envisaged that this may comprise any form ofelectrical device 250 which might operably communicate with theaerosol provision system 1, such as (and certainly not limited to) any of a portable device, such as a tablet computer,smartphone 250A, portable computer, which might be carried by a user of theaerosol provision system 1. - As will be appreciated, being able to selectively enable/disable certain feedback provides a number of technical advantages. For example, by selectively providing certain feedback, the aerosol provision system may operate more efficiently from a power consumption perspective. In addition, the user is not presently with an overwhelming amount of optional feedback which may distract from more critical feedback, while keeping the optional feedback easily accessible via the user interface portion if needed.
- In some embodiments, the first feedback and second feedback may be provided on/by different sections or parts of the feedback portion, or by separate feedback portions. As illustrated in
FIGS. 9A and 9B ,multiple feedback portions aerosol provision system 1, though could in other embodiments (as noted above) be located on some other electrical device (for instance a portable device, such as a tablet computer, smartphone, in some embodiments). - In this way, the user may more easily and efficiently identify more important mandatory feedback information as compared to optional feedback information. As an example, the mandatory first feedback may be provided by
feedback portion 902 and optional second feedback provided byfeedback portions - In accordance with some embodiments, the first feedback F1 is configured to be provided in response to a first predetermined criterion being satisfied. For example, the predetermined condition may be detected using a sensor comprised in the aerosol provision system. Such a sensor may be configured to detect parameters relating to critical operations of the aerosol provision system, such as operational condition of the aerosol provision system and/or a temperature of the aerosol provision system which may reflect a level of safety of the aerosol provision system’s operation. The user may therefore be notified of this change in operational state of the aerosol provision system via the first feedback which, as explained above, may not be selectively prevented from being provided to the feedback portion.
- As discussed briefly above, the first predetermined criterion may relate to an operational state of the
aerosol provision system 1. In some embodiments, the first predetermined criterion comprises a determination being made that the aerosol provision system is faulty. This determination may be made based on a measurement made by a sensor comprised in the aerosol provision system. For example, the determination may be made based on detecting properties of the device components, such as the aerosol generating material transport element 42 (where employed),power source 16, etc. If properties of any of these components falls outside of predetermined normal operating ranges, it may be determined that the aerosol provision system is not operating at a safe standard and is therefore found to be faulty. - The aforementioned determinations may be made by
control circuitry 18 from the aerosol provision system based on sensor measurements received by thecontrol circuitry 18. As illustrated inFIG. 10 ,sensors reservoir 31,aerosol generator 40/aerosol generatingmaterial transport element 42, and power source (battery) 16 respectively. Each of thesensors control circuitry 18 as indicated by the connecting lines inFIG. 10 . - In some embodiments, the first predetermined criterion may comprise a temperature value exceeding a predetermined temperature (as shown in the embodiment of
FIG. 11 , for instance). This predetermined temperature may relate to a temperature of a aerosol generatingmaterial transport element 42 as described above with reference toFIG. 1-6B . In this case, if the temperature of the aerosol generating material transport element rises above a certain temperature, there may be a risk of the aerosol generating material transport element igniting. The temperature of the aerosol generating material transport element may rise in this way if the wick has dried out due to an insufficient amount of aerosol generating material remaining in areservoir 31 of theaerosol provision system 1, or if the aerosol generating material transport element has been consistently heated for a long duration without an opportunity to cool down, for example. The predetermined temperature may be configured to be lower than the ignition temperature of the aerosol generating material transport element by a predetermined margin such that the first feedback is provided (and any remedial action taken) before the aerosol generatingmaterial transport element 42 can ignite and cause damage to theaerosol provision system 1 and/or user. - In another embodiment, the temperature may be the temperature of a
power supply 16 or battery from the aerosol provision system 1 (or from theaerosol provision device 4, where such adevice 4 is employed) as described above with reference toFIG. 1-6B . In this case, if the temperature of thepower source 16 rises above a certain temperature, there may be a significant risk of the power source igniting. Malfunctioning batteries are at risk of such overheating, and therefore sensing the temperature of the power source may simultaneously indicate whether theaerosol provision system 1 is faulty. - In accordance with some embodiments, the second feedback F2 may be configured to be provided in response to a second predetermined criterion being satisfied. Similarly to the first criterion, the second criterion may also be detected using a sensor comprised in the
aerosol provision system 1. Such a sensor may be configured to detect parameters relating to ancillary properties of theaerosol provision system 1. In other words, the second predetermined criterion may relate to properties that are not as a high a priority as the first predetermined criterion in terms of aspects such as safety. In this way, the second feedback is configured to be provided in relation to useful auxiliary information pertaining to the operation of the device where such feedback is not essential to the safe operation of the device but is nonetheless useful to know when required. - For example, in some embodiments, the second criterion comprises a determination being made that a power supply from the
aerosol provision system 1 comprises less than a predetermined amount of remaining power. This advantageously triggers the second feedback to indicate that theaerosol provision system 1 requires charging. However, as the power level may not necessarily be critical to the safe operation of the device, this feedback can be selectively prevented by the user as explained above. - In a more particular embodiment, the second feedback may additionally be configured to indicate the amount of power remaining in the power source 16 (as shown in the embodiment of
FIG. 11 , for instance). This indication may, for example, be provided via the user interface mentioned above. Alternatively, this indication may be provided by a separate display means. - In some embodiments, the second criterion comprises a determination being made that an amount of aerosol generating material comprises less than a predetermined amount. For example, the aforementioned user interface portion may be configured to indicate the remaining amount of aerosol generating material once the predetermined amount has been reached, or alternatively indicate that the predetermined amount has been reached without also indicating the precise amount of remaining aerosol generating material.
- The amount of aerosol generating material remaining in the aerosol, provision system may be measured in a number of different ways. As a specific example, an optical sensor in the
reservoir 31 may be configured to detect the remaining amount of aerosol generating material by sensing the distance to the surface of the aerosol generating material contained in thereservoir 31. As will be appreciated, this distance may change depending on the orientation of theaerosol provision system 1, such that in some embodiments the optical sensor may be configured to only measure the distance when it is determined that the aerosol provision system is in a particular orientation (e.g. as determined by a gyroscopic device comprised in the aerosol provision system). - In some embodiments, the second criterion comprises a determination being made that an aerosol generator from the aerosol provision system has not been operated for generating an aerosol for a period of time which exceeds a predetermined period of time. This may be advantageous as an optional feedback to remind the user to operate the aerosol provision system in the interest of avoiding inefficient use of the
power source 16 in idle periods. As a further particular embodiment, the feedback provision system may be configured to turn off the power source upon determining that a second predetermined period of time has passed since the aerosol provision system was used to generate aerosol, the second predetermined period of time being greater than the first predetermined period of time. This may be further advantageous in improving the efficiency of theaerosol provision system 1 by reducing wasteful use of thepower source 16. - As will be appreciated from the foregoing, a number of different types of first and second feedback may be provided based on a number of different first criterion and second criterion. It should be noted that these feedbacks may be either individually provided to the feedback portion or simultaneously provided to the feedback portion in any combination.
- With respect to any provided first feedback, second feedback, and/or further feedback (such as any provided third feedback F3, as noted above in some embodiments), it will be noted in some embodiments that the feedback F1;F2;F3 may be provided, visually, as part of
display 252 from the feedback provision system, e.g. through the feedback portion comprising adisplay 252, and/or as part of any required modes of operation M1;M2 from the feedback provision system (or aerosol provision system 1). With respect to such embodiments, the outputted feedback may in some cases take the form of an appropriate visual indication on thedisplay 252, as required. - As to what such a visual indication might be, it will be appreciated that this visual indication may take the form of any appropriate (visual) indicia, as required. For instance, the indicia 254 in accordance with some embodiments may comprise a symbol, such as a warning symbol 256 (e.g. an
exclamation point 258, and/or a warning triangle 260), a string oftext 262, an error message, or some other graphical symbol 264. In this way, the indicia may be representative of the underlying purpose of the feedback which is being provided. - In accordance with some embodiments, to better distinguish between the (in some cases, more important) first feedback, and the second (in some cases, potentially optional) feedback, in so far as the first feedback F1 comprises a first indicia 254A on the
display 252, and the second feedback F2 comprises a second indicia 264B on thedisplay 252, in some of these embodiments the first indicia may comprise a first color, with the second indicia comprising a second color which is different from the first color. In this way, through the provision of the different colors, the user may be able to discern more readily when a particular type of feedback is being provided. For instance, in embodiments where the first feedback F1 is provided, which may be indicative of safety critical information, the first color for the first indicia may comprise may be a color more associated with danger, such as a color comprising at least one of black; purple; red; orange; amber; or yellow. In this way, and where the second feedback F2 (or even third feedback F3) is provided - which may be indicative of less safety critical information, the second color (or a third color for the third feedback, where employed) may be a color less associated with danger than the first color, such as a color comprising at least one of blue; green; orange; amber; yellow; or white. Such embodiments are illustrated in the particular embodiment ofFIG. 11 for instance, where the first indicia 254A comprises a red color; the second indicia 254B comprises an amber/orange color, and the third indicia 254C (relating to the third feedback F3) comprising a green color. - Whatever the type of any of the provided first feedback F1 or second feedback F2 (or even third feedback in some embodiments where the third mode of operation is employed) such as the feedback being haptic/visual/acoustic type feedback, it will be appreciated that in accordance with some of these embodiments, the first feedback F1 may be configured to be provided more prominently (such as louder; longer; brighter; and/or stronger) than the second (or third) feedback F2, to better emphasize to the user the more important nature of the first feedback over the second (or third) feedback F2:F3 .This is shown in the embodiment of
FIG. 11 , for instance. - Particularly in embodiments where feedback is configured to be displayed on a
display 252, such as on adisplay 252 from a remoteelectrical device 250 from the feedback provision system, with reference to at least some of these embodiments, thedisplay 252 / feedback portion may be configured to display a graphical representation of the aerosol provision system 1 (as shown in the embodiment ofFIG. 11 for instance). In this way, and in accordance with some embodiments, the feedback portion and/or thedisplay 252 may be configured to display an identifier 266 (such as a graphical representation of 268, and/or a description/name 270) of theaerosol provision system 1 on thedisplay 252, such to allow better allow the user to more easily associate any given feedback (such as the first feedback F1; second feedback F2; and/or third feedback F3) to theaerosol provision system 1 in question. Again, such potential embodiments are illustrated in the embodiments ofFIGS. 11 and 12 for instance. In such embodiments, at least one of the first feedback F1 and second feedback F2 may be provided next to, such as above or below, theidentifier 266. - Noting the above, it will also be seen that the present disclosure correspondingly also provides for a method of controlling the provision of feedback in aerosol feedback provision system comprising an aerosol provision system for generating an aerosol, wherein the method comprises: providing a feedback portion for providing first feedback and second feedback to a user of the aerosol provision system; not allowing the first feedback to be selectively prevented from being provided by the feedback portion; and allowing the second feedback to be selectively prevented from being provided by the feedback portion.
- Appreciating the foregoing, there has accordingly been described aerosol feedback provision system comprising an aerosol provision system for generating an aerosol, and a feedback portion for providing first feedback and second feedback to a user of the aerosol provision system, wherein the feedback provision system is configured to not allow the first feedback to be selectively prevented from being provided by the feedback portion; and is configured to allow the second feedback to be selectively prevented from being provided by the feedback portion.
- There has also been described an aerosol provision system for generating an aerosol, wherein the aerosol provision system further comprises a feedback portion for providing first feedback and second feedback to a user of the aerosol provision system, wherein the aerosol provision system is configured to not allow the first feedback to be selectively prevented from being provided by the feedback portion; and is configured to allow the second feedback to be selectively prevented from being provided by the feedback portion.
- There has also been described an aerosol provision device, for use in an aerosol provision system for generating an aerosol comprising the aerosol provision device and a consumable comprising aerosol-generating material for aerosolizing, wherein the aerosol provision device comprises: a feedback portion for providing first feedback and second feedback to a user of the aerosol provision system, wherein the aerosol provision device is configured to not allow the first feedback to be selectively prevented from being provided by the feedback portion; and is configured to allow the second feedback to be selectively prevented from being provided by the feedback portion.
- There has also been described a feedback portion for a feedback provision system comprising an
aerosol provision system 1. The feedback portion provides a first feedback and second feedback to a user of the aerosol provision system.
