Definitions
- the present disclosure relates to desktop refilling devices, articles for aerosol provision systems and aerosol provision systems.
- Electronic aerosol provision systems such as electronic cigarettes (e-cigarettes) generally contain an aerosol-generating material, such as a reservoir of a source liquid containing a formulation, typically including nicotine, or a solid material such as a tobacco-based product, from which an aerosol is generated for inhalation by a user, for example through heat vaporization.
- an aerosol provision system will typically comprise an aerosol generator, e.g. a heating element, arranged to aerosolise a portion of aerosol-generating material to generate an aerosol in an aerosol generation region of an air channel through the aerosol provision system.
- air is drawn into the device through one or more inlet holes and along the air channel to the aerosol generation region, where the air mixes with the vaporized aerosol generator and forms a condensation aerosol.
- the air drawn through the aerosol generation region continues along the air channel to a mouthpiece, carrying some of the aerosol with it, and out through the mouthpiece for inhalation by the user.
- aerosol provision systems it is common for aerosol provision systems to comprise a modular assembly, often having two main functional parts, namely an aerosol provision device and an article.
- the article will comprise the consumable aerosol-generating material and the aerosol generator (heating element), while the aerosol provision device part will comprise longer-life items, such as a rechargeable battery, device control circuitry and user interface features.
- the aerosol provision device may also be referred to as a reusable part or battery section and the article may also be referred to as a consumable, disposable/replaceable part, cartridge or cartomizer.
- the aerosol provision device and article are mechanically coupled together at an interface for use, for example using a screw thread, bayonet, latched or friction fit fixing.
- the article may be removed from the aerosol provision device and a replacement article may be attached to the device in its place.
- some articles are configured such that, after the aerosol-generating material in the article has been exhausted, the article can be refilled with more aerosol-generating material, thereby allowing the article to be reused.
- the user is able to refill the article using a separate reservoir of aerosol-generating material.
- the aerosol-generating material used to refill the article may be the same or different to the previous aerosol-generating material in the article, thereby allowing the user to change to a different aerosol-generating material without purchasing a new article.
- Refilling the article with aerosol-generating material extends the life of the article as its use is no longer limited by the volume or amount of aerosol-generating material that the article can hold. As a result, the use of the article may be limited by other factors, such as the life of individual components within the article. Continuous use of the article may therefore result in degradation or fault developing in components within the article. The article may therefore become less reliable, the operation of the article less predictable or the article may stop working entirely, each of which has a negative impact on the user experience.
- a desktop refilling device for an article of an aerosol provision system comprising an article interface configured to receive the article, a reservoir interface configured to receive a reservoir, and refilling control circuitry configured to facilitate the transfer of aerosol-generating material from the reservoir to the article, wherein the article interface and/or the reservoir interface are configured to respectively enclose the article and the reservoir inside a housing of the desktop refilling device during the transfer of aerosol-generating material from the reservoir to the article.

- a first end of the refilling device 40 comprises the flat surface 410 to allow the refilling device 40 to be located on a horizontal surface. As illustrated in FIGS.
- the reservoir interface 46 is located further (in other words, a greater distance along the major axis or length of the refilling device 40 ) from the flat surface 410 than the article interface 42 . This ensures that, when the flat surface 410 is placed on another flat surface (such as a horizontal surface), such as in the case of a desktop refilling device as described above, the flat surface 410 aligns with the x-axis (or horizontal direction), and the reservoir interface 46 is located at a higher position than the article interface 42 .

- FIG. 5 A illustrates the holder 420 in the closed configuration 420 a .
- the holder 420 is located substantially within the housing 400 of the refilling device 40 .
- the holder 420 is contained within and/or enclosed by the housing 400 of the refilling device 40 such that the article interface 42 is configured to enclose the article 30 inside the housing 400 of the refilling device 40 when the holder 420 in a closed configuration 420 a .

- the holder 420 is configured to support the article 30 during the transfer of aerosol-generating material 52 from the reservoir 50 to the article 30 .
- the refilling control circuitry 48 may be configured to detect, for example using a sensor or contact electrode, when the holder 420 is in the closed configuration 420 a , and to facilitate the transfer of aerosol-generating material 52 from the reservoir 50 to the article 30 in response to detected that the holder 420 is in the closed configuration 420 a .
- the refilling control circuitry 48 may detect that the holder 420 is in the closed configuration 420 a , but only facilitate the transfer of aerosol-generating material 52 from the reservoir 50 to the article 30 in response to an input by a user of the refilling device 40 , for example via an input means such as a button, touch screen or switch.
- Transferring aerosol-generating material 52 from the reservoir 50 to the article 30 when the holder 420 is in the closed configuration 420 a ensures that the article interface 42 encloses the article 30 inside the housing 400 of the refilling device 40 during the transfer of aerosol-generating material 52 from the reservoir 50 to the article 30 . This prevents the user from touching, interfering with or removing the article 30 during the transfer of aerosol-generating material 52 , thereby improving the safety of the transfer and refilling process.
- the housing 400 of the refilling device 40 comprises an article opening 422 .
- An outer surface 421 of the holder 420 closes the article opening 422 such that the outer surface 421 of the holder 420 lies flush with the housing 400 when the holder 420 is in the closed configuration 420 a .
- the outer surface 421 of the holder 420 therefore substantially confirms to the shape of the housing 400 , thereby forming a portion of the housing 400 .
- FIG. 5 B illustrates the holder 420 in the open configuration 420 b .
- the holder 420 is at least partially located outside the housing 400 of the refilling device 40 .

- the article opening 422 is not closed by the outer surface 421 in the open configuration 420 b , and the article opening 422 provides a gap or hole in the housing 400 of the refilling device 40 through which the holder 420 can slide.
- the holder 420 is configured to receive the article 30 when the holder 420 is in the open configuration 420 b .
- the user since the holder 420 is at least partially located outside the housing 400 of the refilling device 40 in the open configuration 420 b , the user is able to place, position or otherwise couple the article 30 in the holder 420 when the holder 420 is in the open configuration 420 b such that the article 30 is received by the holder 420 of the article interface 42 .
- the holder 420 slides between the open configuration 420 b and the closed configuration 420 a , the holder 420 also transports the article 30 ; in other words, the article 30 slides into and out of the article opening 422 along with the holder 420 .

- the tray 420 is then configured to receive the article 30 downwards in a vertical direction (in other words, a direction perpendicular to the flat surface 410 , in the negative y-direction in FIG. 5 B ).
- the article 30 is therefore lowered from above onto the tray 420 such that the article 30 rests on the tray in a horizontal orientation.
- the holder/tray 420 is configured to receive the article 30 in a horizontal orientation (along the x-axis in FIG. 5 B ) when the refilling device is located on a horizontal surface (i.e. when the flat surface 410 is aligned such that the flat surface 410 is substantially horizontal).
- the article 30 is therefore received in substantially the same orientation as the flat surface 410 (i.e. in the plane of the flat surface 410 ).
- the tray 420 can comprise a trough with a size and shape substantially conforming to a perimeter size and shape of the article 30 .
- the trough is a cut-out which mirrors the size and shape of the article 30 such that the article 30 is securely retained in the tray 420 on each side of the article 30 by the trough, for example by a location fit, similar fit, or press fit. This ensures that the article 30 does not move or roll as the holder 420 moves between the open configuration 420 b and the closed configuration 420 a .
- the trough is also positioned within the tray to ensure that the refilling orifice 34 on the article 30 is located proximate to the refilling outlet 44 when the holder 420 is in the closed configuration 420 a .
- the trough ensures that the refilling orifice 34 of the article 30 is correctly located proximate to the refilling outlet 44 when the holder 420 is in the closed configuration 420 a in order to facilitate the transfer of aerosol generating material into the article 30 .

Description
- The present application is a National Phase entry of PCT Application No. PCT/GB2021/052739, filed Oct. 22, 2021, which claims priority from GB Application No. 2016760.7, filed Oct. 22, 2020 and GB Application No. 2108804.2, Jun. 18, 2021 filed each of which hereby fully incorporated herein by reference.
- The present disclosure relates to desktop refilling devices, articles for aerosol provision systems and aerosol provision systems.
- Electronic aerosol provision systems such as electronic cigarettes (e-cigarettes) generally contain an aerosol-generating material, such as a reservoir of a source liquid containing a formulation, typically including nicotine, or a solid material such as a tobacco-based product, from which an aerosol is generated for inhalation by a user, for example through heat vaporization. Thus, an aerosol provision system will typically comprise an aerosol generator, e.g. a heating element, arranged to aerosolise a portion of aerosol-generating material to generate an aerosol in an aerosol generation region of an air channel through the aerosol provision system. As a user inhales on the device and electrical power is supplied to the aerosol generator, air is drawn into the device through one or more inlet holes and along the air channel to the aerosol generation region, where the air mixes with the vaporized aerosol generator and forms a condensation aerosol. The air drawn through the aerosol generation region continues along the air channel to a mouthpiece, carrying some of the aerosol with it, and out through the mouthpiece for inhalation by the user.
- It is common for aerosol provision systems to comprise a modular assembly, often having two main functional parts, namely an aerosol provision device and an article. Typically the article will comprise the consumable aerosol-generating material and the aerosol generator (heating element), while the aerosol provision device part will comprise longer-life items, such as a rechargeable battery, device control circuitry and user interface features. The aerosol provision device may also be referred to as a reusable part or battery section and the article may also be referred to as a consumable, disposable/replaceable part, cartridge or cartomizer.
- The aerosol provision device and article are mechanically coupled together at an interface for use, for example using a screw thread, bayonet, latched or friction fit fixing. When the aerosol-generating material in an article has been exhausted, or the user wishes to switch to a different article having a different aerosol-generating material, the article may be removed from the aerosol provision device and a replacement article may be attached to the device in its place. Alternatively, some articles are configured such that, after the aerosol-generating material in the article has been exhausted, the article can be refilled with more aerosol-generating material, thereby allowing the article to be reused. In this example, the user is able to refill the article using a separate reservoir of aerosol-generating material. The aerosol-generating material used to refill the article may be the same or different to the previous aerosol-generating material in the article, thereby allowing the user to change to a different aerosol-generating material without purchasing a new article.
- Refilling the article with aerosol-generating material extends the life of the article as its use is no longer limited by the volume or amount of aerosol-generating material that the article can hold. As a result, the use of the article may be limited by other factors, such as the life of individual components within the article. Continuous use of the article may therefore result in degradation or fault developing in components within the article. The article may therefore become less reliable, the operation of the article less predictable or the article may stop working entirely, each of which has a negative impact on the user experience.
- Various approaches are described herein which seek to help address or mitigate some of the issues discussed above.

It should be noted that it is possible for theaerosol generator 36 to be part of theaerosol provision device 20 and thearticle 30 then may comprise the aerosol-generatingmaterial storage area 39 for the aerosol-generatingmaterial 32 such that, when thearticle 30 is coupled with theaerosol provision device 20 via theinterfaces material 32 can be transferred to theaerosol generator 36 in theaerosol provision device 20. - Aerosol-generating material is a material that is capable of generating aerosol, for example when heated, irradiated or energized in any other way. The aerosol-generating
material 32 may, for example, be in the form of a solid, liquid or gel which may or may not contain an active substance and/or flavorants. In some embodiments, the aerosol-generatingmaterial 32 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 dried gel. The amorphous solid is a solid material that may retain some fluid, such as liquid, within it. In some embodiments, the aerosol-generatingmaterial 32 may for example comprise from about 50 wt %, 60 wt % or 70 wt % of amorphous solid, to about 90 wt %, 95 wt % or 100 wt % of amorphous solid. - The aerosol-generating material comprises one or more ingredients, such as one or more active substances and/or flavorants, one or more aerosol-former materials, and optionally one or more other functional materials such as pH regulators, coloring agents, preservatives, binders, fillers, stabilizers, and/or antioxidants.
- The active substance as used herein may be a physiologically active material, which is a material intended to achieve or enhance a physiological response. The active substance may for example be selected from nutraceuticals, nootropics, and psychoactives. The active substance may be naturally occurring or synthetically obtained. The active substance may comprise for example nicotine, caffeine, taurine, theine, vitamins such as B6 or B12 or C, melatonin, cannabinoids, or constituents, derivatives, or combinations thereof. The active substance may comprise one or more constituents, derivatives or extracts of tobacco, cannabis or another botanical.
- In some embodiments, the active substance comprises nicotine. In some embodiments, the active substance comprises caffeine, melatonin or vitamin B12.
- The
aerosol provision device 20 includes apower source 14, such as a battery, configured to supply electrical power to theaerosol generator 36. Thepower source 14 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 14 may be recharged through the charging port (not illustrated), which may, for example, comprise a USB connector. - The
aerosol provision device 20 includesdevice control circuitry 28 configured to control the operation of theaerosol provision system 10 and provide conventional operating functions in line with the established techniques for controlling aerosol provision systems such as electronic cigarettes. The device control circuitry (processor circuitry) 28 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, thedevice control circuitry 28 may comprise power source control circuitry for controlling the supply of electrical power from thepower source 14 to theaerosol generator 36, 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. It will be appreciated the functionality of thedevice control circuitry 28 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. - The
aerosol provision device 20 includes one ormore air inlets 21. In use, as a user inhales on themouthpiece 35, air is drawn into theaerosol provision device 20 through theair inlets 21 and along anair channel 23 to theaerosol generator 36, where the air mixes with the vaporized aerosol-generatingmaterial 32 and forms a condensation aerosol. The air drawn through theaerosol generator 36 continues along theair channel 23 to amouthpiece 35, carrying some of the aerosol with it, and out through themouthpiece 35 for inhalation by the user. Alternatively, the one ormore air inlets 21 may be included on thearticle 30, such that theair channel 23 is entirely contained within thearticle 30. - By way of a concrete example, the
article 30 comprises a housing (formed, e.g., from a plastics material), an aerosol-generatingmaterial storage area 39 formed within the housing for containing the aerosol-generating material 32 (which in this example may be a liquid which may or may not contain nicotine), an aerosol-generating material transfer component 37 (which in this example is a wick formed of e.g., glass or cotton fibers, or a ceramic material configured to transport the liquid from the reservoir using capillary action), an aerosol-generating area containing theaerosol generator 36, and amouthpiece 35. Although not shown, a filter and/or aerosol modifying agent (such as a flavor imparting material) may be located in, or in proximity to, themouthpiece 35. Theaerosol generator 36 of this example comprises a heater element formed from an electrically resistive material (such as NiCr8020) spirally wrapped around the aerosol-generatingmaterial transfer component 37, and located in theair channel 23. The area around the heating element and wick combination is the aerosol-generating area of thearticle 30. -
FIG. 2 is a schematic diagram of anexample article 30 for use in theaerosol provision system 10 illustrated inFIG. 1 , where the same reference signs have been used for like elements between thearticle 30 illustrated inFIG. 1 and thearticle 30 illustrated inFIG. 2 . As per thearticle 30 illustrated inFIG. 1 , thearticle 30 illustrated inFIG. 2 includes an aerosol-generatingmaterial storage area 39 for storing an aerosol-generatingmaterial 32, an aerosol-generatingmaterial transfer component 37, an aerosol generation area containing anaerosol generator 36, and amouthpiece 35. - The
article 30 illustrated inFIG. 2 is configured to be refilled and reused. In other words, the aerosol-generatingmaterial storage area 39 of thearticle 30 illustrated inFIG. 2 can be refilled with aerosol-generatingmaterial 32 once some or all of the aerosol-generatingmaterial 32 contained in the aerosol-generatingmaterial storage area 39 has been exhausted or depleted. To facilitate the refilling or replenishment of aerosol-generatingmaterial 32, thearticle 30 has a refillingtube 33 extending between the aerosol-generatingmaterial storage area 39 and the exterior or an outer surface of the housing of thearticle 30, thereby creating a refillingorifice 34. Aerosol-generatingmaterial 32 can then be inserted into the aerosol-generatingmaterial storage area 39 via the refillingorifice 34 and refillingtube 33. It will be appreciated, however, that such a configuration of a refillingtube 33 and a refillingorifice 34 is not essential, and thearticle 30 may comprise any other suitable means of facilitating the refilling of the aerosol-generatingmaterial storage area 39 withaerosol generating material 32. - The refilling
orifice 34 and/or the refillingtube 33 may be sealable, for example with a cap, one-way valve or septum valve, in order to ensure that aerosol-generatingmaterial 32 does not leak out of the refillingorifice 34. In other words, the refillingorifice 34 can comprise a cap, one-way valve or septum valve. Although the refillingorifice 34 is illustrated inFIG. 2 as being on the same end orsurface 310 of thearticle 30 as theair channel 23 andinterface 22 with theaerosol provision device 20, this is not essential. The refillingorifice 34 may be located at theend 320 of thearticle 30 comprising themouthpiece 35, for example proximate to the outlet of theair channel 23 on themouthpiece 35, such that the refillingtube 33 extends between theend 320 of thearticle 30 comprising themouthpiece 35 and the aerosol-generatingmaterial storage area 39. In this case, thearticle 30 does not necessarily need to be separated from the aerosol-generatingdevice 20 in order to refill thearticle 30 with aerosol-generatingmaterial 32, as the refillingorifice 34 is not obstructed by the aerosol-generatingdevice 20 when thearticle 30 is coupled with theaerosol provision device 20 via theinterfaces - The
article 30 illustrated inFIG. 2 also comprisesarticle control circuitry 38 configured to control the operation of thearticle 30 and store parameters and/or data associated with thearticle 30. The parameters associated with thearticle 30 may include, for example, a serial number and/or stock keeping unit (SKU) for thearticle 30 or other means of identifying the article and/or the type of thearticle 30, a date of manufacture and/or expiry of thearticle 30, an indication of the number of times thearticle 30 has been refilled, the capacity of the aerosol-generatingmaterial storage area 39 and/or the amount of aerosol-generating material remaining in the aerosol-generatingmaterial storage area 39. The parameters associated with the article may include data relating to the aerosol-generating material stored in the aerosol-generatingmaterial storage area 39, such as one or more ingredients, the concentration and/or amount of the ingredients and/or one or more flavorants within the aerosol-generating material. As described above in relation to thedevice control circuitry 28, thearticle control circuitry 38 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. For example, thearticle control circuitry 38 may comprise a microcontroller unit (MCU) or a system on chip (SoC). - The
article 30 illustrated inFIG. 2 also comprises one ormore connectors 31, such as contact electrodes, connected via electrical wiring to theaerosol generator 36 and thearticle control circuitry 38. In use, thearticle 30 is coupled to the aerosol-generatingdevice 20 and theconnectors 31 mate with connectors on the aerosol-generating device, thereby allowing electrical power and electrical current to be supplied from thebattery 14 of the aerosol-generating device to theaerosol generator 36 and thearticle control circuitry 38. As illustrated inFIG. 2 , the one ormore connectors 31 can be located at thesame end 310 of thearticle 30 as theinterface 22. Alternative, the one ormore connectors 31 may form part of theinterface 22 or be located on a different surface of thearticle 30 to theinterface 22, for example a side wall of thearticle 30 proximate to theend 310 with the interface. It will be appreciated that the one ormore connectors 31 can be located on any surface of thearticle 30 so as to provide a complementary fixture or fitting withequivalent connectors 22 on theaerosol provision device 20 and/or refillingdevice 40 as described in more detail below. -
FIG. 3 is a schematic diagram of arefilling device 40 for an article of an aerosol provision system, such as thearticle 30 illustrated inFIG. 2 , and areservoir 50. Thereservoir 50 is a disposable/replaceable part which contains aerosol-generatingmaterial 52. The refilling device facilitates the transfer of the aerosol-generatingmaterial 52 from areservoir 50 couplable to the refilling device to anarticle 30 couplable to the refilling device in order to refill or replenish the aerosol-generatingmaterial storage area 39 of thearticle 30 with aerosol-generating material. In other words, the refillingdevice 40 described herein is a refilling apparatus for anarticle 30 of anaerosol provision system 10. Thearticle 30 can then be reused as part of theaerosol provision system 10 described above, whilst thereservoir 50 can be disposed of when the aerosol-generatingmaterial 52 within thereservoir 50 has been depleted. This allows asingle article 30 to be refilled using one or more reservoirs, thereby increasing the number of uses of asingle article 30. - The refilling
device 40 illustrated inFIG. 3 can be considered a desktop refilling device A desktop refilling device is a refilling device designed for regular use at a single location on or near a desk, table or other solid surface due to its size and power requirements. For example,desktop refilling device 40 can comprise an external power supply, such as a mains power or supply to which therefilling device 40 can be coupled, attached or otherwise connected. The refillingdevice 40 may also comprise an internal power source, such as a battery, configured to supply electrical power to the components of therefilling device 40 in the event that the external power supply is not available or unexpectedly cuts out in the middle of operation. - As illustrated in
FIG. 3 , adesktop refilling device 40 can also comprise aflat surface 410 to facilitate storage of the desktop refilling device on another flat surface, such as a desk, table or other solid surface. This allows thedesktop refilling device 40 to rest stably and level on another surface. Theflat surface 410 may comprise a non-slip mat or coating in order to prevent the desktop refilling device from being knocked or pushed. The non-slip mat may be made of rubber or any other suitable material with a high coefficient of friction. More generally, thedesktop refilling device 40 illustrated inFIG. 3 has theflat surface 410 at a first end of therefilling device 40 and asecond surface 420 at a second end of therefilling device 40. The second end is opposite the first end, such that a major axis or length of therefilling device 40 extends between the first end and the second end. When the first end andflat surface 410 are placed or otherwise located on a horizontal surface (e.g. aligned with x-axis inFIG. 3 ), the major axis or length of therefilling device 40 extends in a vertical direction (aligned with the y-axis inFIG. 3 ) between the first end and the second end. Theflat surface 410 can therefore be considered as the base, bottom or foot of therefilling device 40 whilst thesecond surface 420 can be considered the top or upper surface of therefilling device 40. - As illustrated in
FIG. 3 , the refillingdevice 40 comprises anarticle interface 42 configured to receive thearticle 30. Thearticle interface 42 may comprise a slot, tray, opening or aperture on therefilling device 40 into or onto which thearticle 30 is placed or coupled. Alternatively thearticle interface 42 may comprise a lead or other cable which is attachable or otherwise connectable to thearticle 30. Although onearticle interface 42 is illustrated inFIG. 3 , the refillingdevice 40 may comprise more than onearticle interface 42, for example three, five or ten, depending on the specific design of therefilling device 40. In this case, two or more of the article interfaces 42 may be different such that the refillingdevice 40 is capable of receiving different types of article, or two or more of the article interfaces 42 may be the same such that the refillingdevice 40 is capable of receiving multiple articles of the same type. - As illustrated in
FIG. 3 , thearticle interface 42 is configured to receive thearticle 30 when thearticle 30 is separated from theaerosol provision device 20. As set out above with reference toFIG. 1 , when used as anaerosol provision system 10, the aerosol provision device andarticle 30 are mechanically coupled together viainterfaces article interface 42 is configured such that, before thearticle 30 is received by thearticle interface 42, the article is detached, disconnected or otherwise separated from theaerosol provision device 20 such that only thearticle 30 is received by the article interface 42 (in other words, theaerosol provision system 20 is not received by the article interface 42). This means that theaerosol provision device 20 is not required in order for thearticle 30 to be refilled withaerosol generating material 32. - The refilling
device 40 also comprises one ormore reservoir interfaces 46 configured to receive areservoir 50. In the same fashion as described above in relation to thearticle interface 42, each of the reservoir interfaces 46 may comprise a slot, tray, opening or aperture on therefilling device 40 into or onto which thereservoir 50 is placed or coupled. Alternatively, eachreservoir interface 46 may comprise a lead or other cable which is attachable or otherwise connectable to thereservoir 50. Although tworeservoir interfaces 46 are illustrated inFIG. 3 , this is not essential and therefilling device 40 may comprise fewer or more reservoir interfaces 46, for example one, three, five or ten, depending on the specific design of therefilling device 40. - As illustrated in
FIG. 3 , the one ormore reservoir interfaces 46 can be located above thearticle interface 42. In other words the one or more reservoir interfaces 46 are located at a higher position than thearticle interface 42 such that, in use, the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30 is gravity assisted, thereby reducing the energy required to transfer aerosol-generatingmaterial 52. The x-axis shown inFIG. 3 aligns with a horizontal direction and the y-axis shown inFIG. 3 aligns with a vertical direction. A first end of therefilling device 40 comprises theflat surface 410 to allow the refilling device is located on a horizontal surface. As illustrated inFIG. 3 , the one or more reservoir interfaces 46 are located further (in other words, a greater distance along the major axis or length of the refilling device 40) from theflat surface 410 than the above thearticle interface 42. This ensures that, when theflat surface 410 is placed on another flat surface (such as a horizontal surface), such as in the case of a desktop refilling device as described above, theflat surface 410 aligns with the x-axis (or horizontal direction), and the one or more reservoir interfaces 46 are located at a higher position than thearticle interface 42. - The refilling
device 40 also comprises refillingcontrol circuitry 48 configured to control the operation of therefilling device 40. In particular, the refillingcontrol circuitry 48 is configured to facilitate the transfer of aerosol-generatingmaterial 52 from areservoir 50 to thearticle 30. As described above in relation to thedevice control circuitry 28, the refillingcontrol circuitry 48 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. For example, the refillingcontrol circuitry 48 may comprise a microcontroller unit (MCU) or a system on chip (SoC). - The refilling
device 40 also comprises ahousing 400 which contains and encloses the components of therefilling device 40. As illustrated inFIG. 3 , thearticle interface 42 and the one or more reservoir interfaces 46 are located inside thehousing 400 of the refilling device. Thearticle interface 42 is therefore configured to enclose thearticle 30 and the one ormore reservoir interfaces 46 configured to enclose thereservoir 50 inside thehousing 400 of therefilling device 40 during the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30. Thearticle interface 42 and/or the reservoir interfaces 46 may comprise a door, cover or flap which can be shut when thearticle 30 andreservoir 50 are respectively received by thearticle interface 42 and the one ormore reservoir interfaces 46 such that thearticle 30 and thereservoir 50 are fully contained within or otherwise enclosed by thehousing 400 of therefilling device 40. - As described above, the
reservoir 50 comprises aerosol-generatingmaterial 52 for transferring, by the refillingdevice 40, to thearticle 30 in order to refill or replenish the aerosol-generatingmaterial 32 in the aerosol-generatingmaterial storage area 39 of thearticle 30. - The
reservoir 50 illustrated inFIG. 3 also comprisesreservoir control circuitry 58 configured to control thereservoir 50 and store parameters and/or data associated with thereservoir 50. The parameters associated with thereservoir 50 may include, for example data indicative of an amount of aerosol-generatingmaterial 52 stored in thereservoir 50, data relating to the aerosol-generatingmaterial 52 stored in thereservoir 50, such as one or more ingredients, the concentration and/or amount of the ingredients and/or one or more flavorants within the aerosol-generatingmaterial 52. The data may also comprise an identifier, such as a serial number and/or SKU for thereservoir 50 or other means of identifying thereservoir 50 and/or the type of thereservoir 50, and a date of manufacture and/or expiry of thereservoir 50. As described above in relation to thedevice control circuitry 28, thereservoir control circuitry 58 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. For example, thereservoir control circuitry 58 may comprise a microcontroller unit (MCU) or a system on chip (SoC). Alternatively, thereservoir control circuitry 58 may comprise a code printed onto the reservoir, such as a barcode or QR code, or an NFC chip or other form of passive tag. - The
reservoir 50 can have a volume of 10 ml or more, for example 20ml, 50 ml or 100 ml. In other words, the reservoir is configured to contain 10 ml or more of aerosol-generatingmaterial 52 when thereservoir 50 is filled withaerosol generating material 52. At least one of the one or more reservoir interfaces 46 is then configured to receive a reservoir with a volume of 10 ml or more. - The
reservoir 50 can also have a larger volume than thearticle 30. For example, the volume of the reservoir can be at least 5 times greater than the volume of the article, for example times, 20 times or 50 times greater. In other words, the reservoir is configured to contain, when filled with aerosol-generatingmaterial 52, a volume of aerosol-generatingmaterial 52 at least 5 times greater than the aerosol-generatingmaterial storage area 39 of thearticle 30. This allows thesame reservoir 50 to be used to refill the article at least 5 times. At least one of the one or more reservoir interfaces 46 is then configured to receive a reservoir with a volume at least times greater than a volume of the article thearticle interface 42 is configured to receive. - The refilling
device 40 illustrated inFIG. 3 also comprises one ormore connectors 41, such as contact electrodes, connected via electrical wiring to therefilling control circuitry 48 and the power source (not illustrated). Theconnectors 41 are located proximate to or as part of thearticle interface 42. This facilitates communication between the refillingcontrol circuitry 48 and thearticle control circuitry 38; theconnectors 31 on thearticle 30 mate with theconnectors 41 on therefilling device 40 when thearticle 30 is received by thearticle interface 42, thereby allowing power to be supplied from the refillingdevice 40 to thearticle control circuitry 38 and electrical signals to be transferred between the refillingcontrol circuitry 48 and thearticle control circuitry 38. Theconnectors 41 may be arranged relative to thearticle interface 42 in a pattern and position matching/mirroring theconnectors 31 on thearticle 30 in order to facilitate the mating of theconnectors 31 on thearticle 30 and theconnectors 41 on therefilling device 40 when the article is received by thearticle interface 42. - In the same fashion, the refilling
device 40 illustrated inFIG. 3 also comprises one ormore connectors 47, such as contact electrodes, located proximate to or as part of each of the reservoir interfaces 46 and connected via electrical wiring to therefilling control circuitry 48 and the power source (not illustrated). Theconnectors 47 mate with theconnectors 51 on thereservoir 50 when thereservoir 50 is received by thereservoir interface 46, thereby allowing power to be supplied from the refillingdevice 40 to thereservoir control circuitry 58 and electrical signals to be transferred between the refillingcontrol circuitry 48 and thereservoir control circuitry 58. Theconnectors 47 may be arranged relative to thereservoir interface 46 in a pattern and position matching/mirroring theconnectors 51 on thereservoir 50 in order to facilitate the mating of theconnectors 51 on thereservoir 50 and theconnectors 47 on therefilling device 40 when areservoir 50 is received by one of the reservoir interfaces 46. - Although the
connectors - The refilling
device 40 illustrated inFIG. 3 also comprises a refillingoutlet 44 located proximate to or as part of thearticle interface 42, a refillinginlet 45 located proximate to or as part of each of the reservoir interfaces 46, and aduct 43 connecting each refillinginlet 45 to the refillingoutlet 44. The refillingoutlet 44 is configured to mate with the refillingorifice 34 on thearticle 30 when the article is received by thearticle interface 42, and each refillinginlet 45 is configured to mate with areservoir outlet 55 when areservoir 50 is received by the correspondingreservoir interface 46. Theduct 43 is configured to facilitate the transfer of aerosol-generatingmaterial 52 from each of the refillinginlets 45 to the refillingoutlet 44, thereby providing a transfer path for aerosol-generatingmaterial 52 from thereservoir 50 through the refillingdevice 40 and into thearticle 30. - Although the refilling
outlet 44 is illustrated inFIG. 3 as being on the same end or surface of thearticle interface 42 as theconnectors 41, this is not essential. The refillingoutlet 44 may be located anywhere proximate to or in thearticle interface 42 relative to theconnectors 41 in order for the refillingoutlet 44 to mate with the refillingorifice 34 on thearticle 30 whilst theconnectors 41 on therefilling device 40 mate with theconnectors 31 on thearticle 30 when thearticle 30 is received by thearticle interface 30. Similarly, the refillinginlet 45 may be located anywhere proximate to or in eachreservoir interface 46 relative to theconnectors 47 in order for the refillinginlet 45 to mate with thereservoir outlet 55 on thereservoir 50 whilst theconnectors 47 on therefilling device 40 mate with theconnectors 51 on thereservoir 50 when areservoir 50 is received by areservoir interface 46. - Further, as described above, the refilling
device 40 may be configured to receive different types, designs or configuration ofarticle 30 using thesame article interface 42. In this case, there may be multiple configurations ofconnectors 41 and/or refillingoutlets 44 proximate to or in thearticle interface 42 in order to facilitate thesame article interface 42 receiving different types, designs or configurations ofarticle 30. Equally, there may be multiple configurations ofconnectors 47 and/or refillinginlets 45 proximate to or in eachreservoir interface 46 in order to facilitate thesame reservoir interface 46 receiving different types, designs or configurations ofreservoir 50. Alternatively or in addition, the configuration ofconnectors 47 and/or refilling inlets proximate to or in the one or more of the reservoir interfaces 46 may be different such that different reservoir types are received bydifferent reservoir interfaces 46 of thesame refilling device 40. - One or more of the refilling
outlet 44, the refillinginlets 45, thereservoir outlet 55 and theduct 43 may also include a means of controlling the rate and/or direction of transfer of the aerosol-generatingmaterial 52, for example a ball valve, needle valve or diaphragm to control the rate of transfer and/or a one way valve such as a check valve or non-return valve to control the direction of transfer. For example, a one way valve may be located at or proximate to each of the refillingoutlet 44, the refillinginlets 45 and thereservoir outlets 55 to ensure that aerosol-generatingmaterial 52 can only be transferred from thereservoir 50 to therefilling device 40 and from the refillingdevice 40 to thearticle 30, whilst a single ball valve or diaphragm may be located on or in theduct 43 of therefilling device 40 in order to control the flow rate of aerosol-generatingmaterial 52 from thereservoir 50 through the refillingdevice 40 and into thearticle 30. Equally, a ball valve or diaphragm may be located proximate to each refillinginlet 45 in order to independently control the rate of transfer of aerosol-generatingmaterial 52 into each of the refillinginlets 45 or from each of the refillinginlets 45 into theduct 43. For example, this allows the refillingcontrol circuitry 48 to prevent a first aerosol-generatingmaterial 52 being transferred from afirst reservoir 50 whilst a second aerosol-generatingmaterial 52 is being transferred from asecond reservoir 50 to thearticle 30. This also allows the refillingcontrol circuitry 48 to facilitate the transfer the first aerosol-generatingmaterial 52 from thefirst reservoir 50 and the second aerosol-generatingmaterial 52 from thesecond reservoir 50 simultaneously to thearticle 30, but at different transfer rates, thereby creating an aerosol-generatingmaterial 32 in thearticle 30 containing a mixture of the first aerosol-generatingmaterial 52 and the second aerosol-generatingmaterial 52 at different concentrations. - The refilling
device 40 illustrated inFIG. 3 also comprises adevice interface 49 configured to receive theaerosol provision device 20. As described above, thearticle interface 42 is configured to receive thearticle 30 when thearticle 30 is separated from theaerosol provision device 20, such that theaerosol provision device 20 is not received by thearticle interface 42. Theaerosol provision device 20 can then be received by aseparate device interface 49 as illustrated inFIG. 3 . This allows thedevice interface 49 and thearticle interface 42 to be located separately on therefilling device 40, for example on different sides of therefilling device 40, such that theaerosol provision device 20 can be coupled to therefilling device 40 independently of thearticle 30. As described above, this also means that theaerosol provision device 20 is not required in order for thearticle 30 to be refilled withaerosol generating material 32. - The
device interface 49 can be configured to receive theaerosol provision device 20 in order to supply electrical power from the refillingdevice 40 to theaerosol provision device 20. This electrical power can be used, for example, to recharge the power source orbattery 14 of theaerosol provision device 20 and to facilitate the transfer of electrical signals between the refillingcontrol circuitry 48 and thedevice control circuitry 28. This allows the user to use therefilling device 40 as a means of charging theaerosol provision device 20 whilst thearticle 30 is being replenished with aerosol-generatingmaterial 32, thereby reducing the number of associated devices needed to operate and maintain theaerosol provision system 10. Thedevice interface 49 may be a wired interface, such as using electrical connectors as described above, or a wireless interface such as inductive or capacitive coupling. Thedevice interface 49 may also be configured to the transfer of data between the refillingcontrol circuitry 48 and thedevice control circuitry 28. The refillingcontrol circuitry 48 may be configured to read data from the aerosol provision device and/or write data to theaerosol provision device 20, for example to perform a software update, thereby installing an updated version of software onto thedevice control circuitry 28. - As set out above, the refilling
device 40 facilitates the transfer of aerosol-generatingmaterial 52 from areservoir 50 couplable to therefilling device 40 to anarticle 30 couplable to therefilling device 40 in order to refill or replenish thearticle 30 so that it can be reused as part of theaerosol provision system 10. In particular, the refillingcontrol circuitry 48 is configured to facilitate the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30 in response to detecting that thearticle 30 has been received by the refillingdevice 40. - By way of a concrete example, when a
reservoir 50 is received by one of the reservoir interfaces 47, theconnectors 47 located proximate to or in the correspondingreservoir interface 46 mate with theconnectors 51 on thereservoir 50 and the refillinginlet 45 located proximate to or in the correspondingreservoir interface 46 mates with thereservoir outlet 55. When anarticle 30 is received by thearticle interface 42, theconnectors 41 located proximate to or in thearticle interface 42 mate with theconnectors 31 on thearticle 30 and the refillingoutlet 45 mates with the refillingorifice 34 on thedevice 30. The refillingcontrol circuitry 48 is then configured to facilitate the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30 by facilitating the transfer of aerosol-generatingmaterial 52 from thereservoir 50 into theduct 42 of therefilling device 40 via thereservoir outlet 51 and the refillinginlet 45, and from theduct 42 of therefilling device 40 into the aerosol-generatingmaterial storage area 39 of thearticle 30 via the refillingoutlet 44, the refillingorifice 34 and the refillingtube 33. - In the examples where the
refiling device 40 has a plurality of reservoir interfaces 46, the refillingcontrol circuitry 48 is configured to selectively facilitate the transfer of aerosol-generatingmaterial 52 from areservoir 50 received by one of the reservoir interfaces 46, for example in response to a determination that only one of the reservoir interfaces 46 has received areservoir 50, or in response to a selection of aparticular reservoir 50 from which aerosol-generatingmaterial 52 should be transferred, for example a user input or a determination based on one or more parameters of each of thereservoirs 50 stored on the respectivereservoir control circuitry 58. In this case, the refillingcontrol circuitry 48 is configured to receive, from a user of therefilling device 40, a selection of one ormore reservoir interfaces 46 and selectively facilitate the transfer of aerosol-generatingmaterial 52, from eachreservoir 50 connected to one of the one or more selectedreservoir interfaces 46, to thearticle 30 when thearticle 30 is coupled to the refilling device. In other words, the refillingcontrol circuitry 48 is configured to only transfer aerosol-generatingmaterial 52 from areservoir 50 connected to a selectedreservoir interface 46, and prevent aerosol-generatingmaterial 52 from being transferred from anyother reservoir 50 connected to therefilling device 40. - Although not illustrated, in some examples, the refilling
device 40 can comprise a tank, container or other such receptacle for storing aerosol-generatingmaterial 52 received from thereservoir 50, for example when areservoir 50 is received by thereservoir interface 46 without anarticle 30 being received by thearticle interface 42, thereby allowing thereservoir 50 to be disconnected from thereservoir interface 46 before anarticle 30 is received by thearticle interface 42. In this case, the aerosol-generatingmaterial 52 is stored in the receptacle of therefilling device 40 until such a time that it can be transferred to anarticle 30 received by thearticle interface 42. In this case,control circuitry 48 of therefilling device 40 is configured to facilitate the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to the receptacle, and subsequently and separately to facilitate the transfer of the aerosol-generatingmaterial 52 from the receptacle to thearticle 42. - The receptacle of the
refilling device 40 can also be used to facilitate the mixing of aerosol-generatingmaterial 52 before it is transferred to thearticle 30. For example, if afirst reservoir interface 46 receives afirst reservoir 50 containing a first aerosol-generatingmaterial 52 and asecond reservoir interface 46 receives asecond reservoir 50 containing a second aerosol-generatingmaterial 52, then the refillingcontrol circuitry 48 can be configured to facilitate the transfer of the first aerosol-generatingmaterial 52 from thefirst reservoir 50 into the receptacle, and facilitate the transfer of the second aerosol-generatingmaterial 52 from the second reservoir into the receptacle. The first aerosol-generatingmaterial 52 and the second aerosol-generatingmaterial 52 can then be mixed in the receptacle, and the mixture of the first aerosol-generatingmaterial 52 and the second aerosol-generatingmaterial 52 transferred to the article -
FIG. 4 is a schematic diagram of anexample article 30 for use in theaerosol provision system 10 illustrated inFIG. 1 , where the same reference signs have been used for like elements between thearticle 30 illustrated inFIG. 1 andFIG. 2 and thearticle 30 illustrated inFIG. 4 . As per thearticle 30 illustrated inFIGS. 1 and 2 , thearticle 30 illustrated inFIG. 4 includes an aerosol-generatingmaterial storage area 39 for storing an aerosol-generatingmaterial 32, an aerosol-generatingmaterial transfer component 37, an aerosol generation area containing anaerosol generator 36, amouthpiece 35,article control circuitry 38 and one or more one ormore connectors 31. Although the aerosol-generatingmaterial storage area 39 is illustrated inFIG. 4 as being either side of theaerosol generator 36 and theair channel 23, the aerosol-generatingmaterial storage area 39 can be a single component entirely or substantially surrounding theaerosol generator 36 and theair channel 23. - Like the
article 30 illustrated inFIG. 2 , thearticle 30 illustrated inFIG. 4 is configured to be refilled and reused. In other words, the aerosol-generatingmaterial storage area 39 of thearticle 30 illustrated inFIG. 4 can be refilled with aerosol-generatingmaterial 32 once some or all of the aerosol-generatingmaterial 32 contained in the aerosol-generatingmaterial storage area 39 has been exhausted or depleted. To facilitate the refilling or replenishment of aerosol-generatingmaterial 32, thearticle 30 has a refillingtube 33 extending between the aerosol-generatingmaterial storage area 39 and the exterior or an outer surface of the housing of thearticle 30, thereby creating a refillingorifice 34. In the example illustrated inFIG. 4 , the refillingorifice 34 is located on aside wall 330 of thearticle 30. In other words, theinterface 22 to couple thearticle 30 to theaerosol provision device 20 and one ormore connectors 31 are located at afirst end 310 of thearticle 30. Asecond end 320 is located opposite thefirst end 310 along an axis extending between thefirst end 310 and the second end 320 (the x-axis in the example illustrated inFIG. 4 ). The refillingorifice 34 is then located on aside wall 330 of thearticle 30 between thefirst end 310 and thesecond end 320. - As illustrated in
FIG. 4 , thearticle 30 is generally elongate with an axis A (parallel with the x-axis inFIG. 4 ) extending centrally through thearticle 30 between thefirst end 310 and thesecond end 320. The refillingorifice 34 is located on thesidewall 330 at a distance furthest from this central axis A. In other words, the refillingorifice 34 is located at the greatest radial point away from the central axis A. This facilitates refilling of thearticle 30, and in particular the venting of air from thearticle 30 during refilling, when the article is refilled with the axis A aligned in a horizontal direction (parallel with the x-axis inFIG. 4 ) as is described in more detail below. Alternatively, the refillingorifice 34 may be located at thesecond end 320 of thearticle 30, such that refillingorifice 34 is located at the greatest point or distance away from thefirst end 310 of thearticle 30 in the axis extending between thefirst end 310 and thesecond end 320. - In a similar fashion to the article illustrated in
FIG. 2 , aerosol-generatingmaterial 32 can then be inserted into the aerosol-generatingmaterial storage area 39 of thearticle 30 illustrated inFIG. 4 via the refillingorifice 34 and refillingtube 33. As described above, the refillingorifice 34 and/or the refillingtube 33 may be sealable, for example with a cap, one-way valve or septum valve. In other words, the refillingorifice 34 can comprise a cap, one-way valve or septum valve. - As illustrated in
FIG. 4 , themouthpiece 35 is located at thesecond end 320. In other words, themouthpiece 35 is opposite theinterface 22 with theaerosol provision device 20. Themouthpiece 35 may be an integral part of thearticle 30 or alternatively themouthpiece 35 may be a separate component. In the latter case, thesecond end 320 of thearticle 30 is configured to receive themouthpiece 35, such that themouthpiece 35 can be attached to thearticle 30 when thearticle 30 is to be used as part of anaerosol provision system 10, and themouthpiece 35 can be detached or otherwise removed from thearticle 30 before thearticle 30 is received by thearticle interface 42 of therefilling device 40. -
FIGS. 5A and 5B are schematic diagrams of arefilling device 40 for an article of an aerosol provision system, such as thearticle 30 illustrated inFIG. 2 orFIG. 4 , and thereservoir 50 illustrated inFIG. 3 orFIGS. 7A and 7B . The same reference signs have been used for like elements between the refillingdevice 40 illustrated inFIG. 3 and the refilling device illustrated inFIGS. 5A and 5B . Like the refillingdevice 40 illustrated inFIG. 3 , the refillingdevice 40 illustrated inFIGS. 5A and 5B comprises anarticle interface 42 configured to receive thearticle 30, areservoir interface 46 configured to receive areservoir 50, aduct 43 connecting a refillinginlet 45 to arefilling outlet 44, and refillingcontrol circuitry 48 configured to control the operation of therefilling device 40. - Like the refilling
device 40 illustrated inFIG. 3 , the refillingdevice 40 illustrated inFIGS. 5A and 5B facilitates the transfer of the aerosol-generatingmaterial 52 from areservoir 50 to thearticle 30 in order to refill or replenish the aerosol-generatingmaterial storage area 39 of thearticle 30 with aerosol-generating material. In other words, the refillingdevice 40 is a refilling apparatus for anarticle 30 of anaerosol provision system 10. - The refilling
device 40 illustrated inFIGS. 5A and 5B can also be considered adesktop refilling device 40. As described above, a desktop refilling device is a refilling device designed for regular use at a single location on or near a desk, table or other solid surface due to its size and power requirements. For example,desktop refilling device 40 can comprise an external power supply, such as a mains power or supply to which therefilling device 40 can be coupled, attached or otherwise connected. The refillingdevice 40 may also comprise an internal power source, such as a battery, configured to supply electrical power to the components of therefilling device 40 in the event that the external power supply is not available or unexpectedly cuts out in the middle of operation. Additionally, the desktop refilling device may have one or more sides with a length of at least 100 mm, such 200 or 500 mm. - Like the refilling
device 40 illustrated inFIG. 3 , the refillingdevice 40 illustrated inFIGS. 5A and 5B comprises aflat surface 410 to facilitate storage of thedesktop refilling device 40 on another flat surface, such as a desk, table or other solid surface. This allows thedesktop refilling device 40 to rest stably and level on another surface. Theflat surface 410 may comprise a non-slip mat or coating in order to prevent the desktop refilling device from being knocked or pushed. The non-slip mat may be made of rubber or any other suitable material with a high coefficient of friction. More generally, thedesktop refilling device 40 illustrated inFIGS. 5A and 5B has theflat surface 410 at a first end of therefilling device 40 and asecond surface 420 at a second end of therefilling device 40. The second end is opposite the first end, such that a major axis or length of therefilling device 40 extends between the first end and the second end. When the first end andflat surface 410 are placed or otherwise located on a horizontal surface (e.g. aligned with x-axis inFIGS. 5A and 5B ), the major axis or length of therefilling device 40 extends in a vertical direction (aligned with the y-axis inFIGS. 5A and 5B ) between the first end and the second end. Theflat surface 410 can therefore be considered as the base, bottom or foot of the refilling device The refillingdevice 40 may comprise a plurality of flat surfaces, for example one at each of four corners of therefilling device 40 such that the plurality of flat surfaces form feet or legs to support therefilling device 40 on another flat surface. - As illustrated in
FIGS. 5A and 5B , thereservoir interface 46 is located above thearticle interface 42. In other words thereservoir interface 46 is located at a higher position than thearticle interface 42 such that, in use, the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30 is gravity assisted, thereby reducing the energy required to transfer aerosol-generatingmaterial 52. The x-axis shown inFIGS. 5A and 5B aligns with a horizontal direction and the y-axis shown inFIGS. 5A and 5B aligns with a vertical direction. A first end of therefilling device 40 comprises theflat surface 410 to allow therefilling device 40 to be located on a horizontal surface. As illustrated inFIGS. 5A and 5B , thereservoir interface 46 is located further (in other words, a greater distance along the major axis or length of the refilling device 40) from theflat surface 410 than thearticle interface 42. This ensures that, when theflat surface 410 is placed on another flat surface (such as a horizontal surface), such as in the case of a desktop refilling device as described above, theflat surface 410 aligns with the x-axis (or horizontal direction), and thereservoir interface 46 is located at a higher position than thearticle interface 42. - As illustrated in
FIGS. 5A and 5B , thearticle interface 42 is configured to receive thearticle 30 when thearticle 30 is separated from theaerosol provision device 20. As set out above with reference toFIG. 1 , when used as anaerosol provision system 10, theaerosol provision device 20 andarticle 30 are mechanically coupled together viainterfaces article interface 42 is configured such that, before thearticle 30 is received by thearticle interface 42, the article is detached, disconnected or otherwise separated from theaerosol provision device 20 such that only thearticle 30 is received by the article interface 42 (in other words, theaerosol provision system 20 is not received by the article interface 42). This means that theaerosol provision device 20 is not required in order for thearticle 30 to be refilled withaerosol generating material 32. - The
article interface 42 illustrated inFIGS. 5A and 5B comprises aholder 420. Theholder 420 is configured to slide between aclosed configuration 420 a and anopen configuration 420 b. Thehousing 400 of therefilling device 40 comprises anarticle opening 422, and the holder is configured to slide into and out of thearticle opening 422. Theholder 420 and a portion of therefilling device 40 may comprise rails and corresponding grooves to allow theholder 420 to side in a planar fashion (e.g. along the x-axis as illustrated inFIGS. 5A and 5B ). In other words, theholder 420 is configured to slide in a horizontal direction when therefilling device 40 is located on a horizontal surface (i.e. when the first end andflat surface 410 are placed or otherwise located on a horizontal surface aligned with x-axis inFIGS. 5A and 5B ). -
FIG. 5A illustrates theholder 420 in theclosed configuration 420 a. When theholder 420 in aclosed configuration 420 a, theholder 420 is located substantially within thehousing 400 of therefilling device 40. In other words, theholder 420 is contained within and/or enclosed by thehousing 400 of therefilling device 40 such that thearticle interface 42 is configured to enclose thearticle 30 inside thehousing 400 of therefilling device 40 when theholder 420 in aclosed configuration 420 a. The refillingcontrol circuitry 48 is then configured to facilitate the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30 when theholder 420 is in theclosed configuration 420 a. In other words, theholder 420 is configured to support thearticle 30 during the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30. - The refilling
control circuitry 48 may be configured to detect, for example using a sensor or contact electrode, when theholder 420 is in theclosed configuration 420 a, and to facilitate the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30 in response to detected that theholder 420 is in theclosed configuration 420 a. Alternatively, the refillingcontrol circuitry 48 may detect that theholder 420 is in theclosed configuration 420 a, but only facilitate the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30 in response to an input by a user of therefilling device 40, for example via an input means such as a button, touch screen or switch. Transferring aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30 when theholder 420 is in theclosed configuration 420 a ensures that thearticle interface 42 encloses thearticle 30 inside thehousing 400 of therefilling device 40 during the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30. This prevents the user from touching, interfering with or removing thearticle 30 during the transfer of aerosol-generatingmaterial 52, thereby improving the safety of the transfer and refilling process. - As described above, the
housing 400 of therefilling device 40 comprises anarticle opening 422. Anouter surface 421 of theholder 420 closes the article opening 422 such that theouter surface 421 of theholder 420 lies flush with thehousing 400 when theholder 420 is in theclosed configuration 420 a. Theouter surface 421 of theholder 420 therefore substantially confirms to the shape of thehousing 400, thereby forming a portion of thehousing 400. -
FIG. 5B illustrates theholder 420 in theopen configuration 420 b. In the open configuration, theholder 420 is at least partially located outside thehousing 400 of therefilling device 40. In other words, at least a portion of theholder 420 is not enclosed or contained within thehousing 400 when theholder 420 is in theopen configuration 420 b. As illustrated inFIG. 8B , theouter surface 421 of theholder 420 is displaced away from thehousing 400 along the x-axis, such that theouter surface 421 is not flush with thehousing 400 when theholder 420 is in theopen configuration 420 b. Accordingly, the article opening 422 is not closed by theouter surface 421 in theopen configuration 420 b, and the article opening 422 provides a gap or hole in thehousing 400 of therefilling device 40 through which theholder 420 can slide. - The
holder 420 is configured to receive thearticle 30 when theholder 420 is in theopen configuration 420 b. In other words, since theholder 420 is at least partially located outside thehousing 400 of therefilling device 40 in theopen configuration 420 b, the user is able to place, position or otherwise couple thearticle 30 in theholder 420 when theholder 420 is in theopen configuration 420 b such that thearticle 30 is received by theholder 420 of thearticle interface 42. When theholder 420 slides between theopen configuration 420 b and theclosed configuration 420 a, theholder 420 also transports thearticle 30; in other words, thearticle 30 slides into and out of the article opening 422 along with theholder 420. - The holder illustrated in
FIG. 5B is atray 420 configured to receive thearticle 30 from above such that thearticle 30 rests on thetray 420 when therefilling device 40 is located on a horizontal surface. As described above, the refillingdevice 40 has aflat surface 410 to facilitate storage of therefilling device 40 on another flat surface. As illustrated inFIG. 5B , theflat surface 410 can be aligned such that the flat surface is substantially horizontal (along the x-axis inFIG. 5B ). Thetray 420 is then configured to receive thearticle 30 downwards in a vertical direction (in other words, a direction perpendicular to theflat surface 410, in the negative y-direction inFIG. 5B ). Thearticle 30 is therefore lowered from above onto thetray 420 such that thearticle 30 rests on the tray in a horizontal orientation. In other words, the holder/tray 420 is configured to receive thearticle 30 in a horizontal orientation (along the x-axis inFIG. 5B ) when the refilling device is located on a horizontal surface (i.e. when theflat surface 410 is aligned such that theflat surface 410 is substantially horizontal). Thearticle 30 is therefore received in substantially the same orientation as the flat surface 410 (i.e. in the plane of the flat surface 410). - The
tray 420 can comprise a trough with a size and shape substantially conforming to a perimeter size and shape of thearticle 30. In other words, the trough is a cut-out which mirrors the size and shape of thearticle 30 such that thearticle 30 is securely retained in thetray 420 on each side of thearticle 30 by the trough, for example by a location fit, similar fit, or press fit. This ensures that thearticle 30 does not move or roll as theholder 420 moves between theopen configuration 420 b and theclosed configuration 420 a. The trough is also positioned within the tray to ensure that the refillingorifice 34 on thearticle 30 is located proximate to the refillingoutlet 44 when theholder 420 is in theclosed configuration 420 a. In other words, the trough ensures that the refillingorifice 34 of thearticle 30 is correctly located proximate to the refillingoutlet 44 when theholder 420 is in theclosed configuration 420 a in order to facilitate the transfer of aerosol generating material into thearticle 30. - As can be seen by comparing the axes in
FIGS. 4 and 5B , thearticle 30 is received by theholder 420 in a horizontal orientation such at that the elongate length extending centrally through thearticle 30 between thefirst end 310 and the second end 320 (along the axis A inFIG. 4 ) aligns with a horizontal direction (parallel with the x-axis) when thearticle 30 rests on or in theholder 420 and therefilling device 40 is located on a horizontal surface (i.e. when theflat surface 410 is aligned such that theflat surface 410 is substantially horizontal). As described above with reference toFIG. 4 , this results in the refillingorifice 34 being located at the highest point on thearticle 30 since the refillingorifice 34 is located on thesidewall 330 at a distance furthest from the central axis A. In other words, the refillingorifice 34 is the point on thearticle 30 which is the furthest distance from theflat surface 410 when thearticle 30 rests on or in the holder 420 (i.e. when thearticle 30 is received by the holder 420). This facilitates refilling of thearticle 30, and in particular the venting of air from thearticle 30 during refilling, since the refillingorifice 34 is located at the highest point on thearticle 30, resulting in air in thearticle 30 being displaced upwards (along the y-axis) to the refillingorifice 34 during the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30. - Although not illustrated, the
holder 420 may comprise the one ormore connectors 41, such as contact electrodes, connected via electrical wiring to therefilling control circuitry 48 to facilitate communication between the refillingcontrol circuitry 48 and thearticle control circuitry 38; theconnectors 31 on thearticle 30 mate with theconnectors 41 on theholder 420 when thearticle 30 is received by theholder 420, thereby allowing power to be supplied from the refillingdevice 40 to thearticle control circuitry 38 and electrical signals to be transferred between the refillingcontrol circuitry 48 and thearticle control circuitry 38. Theconnectors 41 may be arranged relative to theholder 420, for example in the tray and/or trough, in a pattern and position matching/mirroring theconnectors 31 on thearticle 30 in order to facilitate the mating of theconnectors 31 on thearticle 30 and theconnectors 41 on theholder 420 when thearticle 30 is received by theholder 420. - Although not illustrated, a motor may be connected to the
holder 420, with the refillingcontrol circuitry 48 configured to operate the motor to slide theholder 420 between theopen configuration 420 b and theclosed configuration 420 a. Alternatively, theholder 420 may comprise a biasing means, such as a spring, configured to bias theholder 420 towards theopen location 420 b. A force then needs to be applied on theholder 420 to overcome the biasing means and slide theholder 420 to theclosed configuration 420 a. In this case, there may be a latch, clip or other retaining mechanism to hold theholder 420 in theclosed configuration 420 a. - The refilling
control circuitry 48 can be configured to operate the motor to slide theholder 420 into theclosed configuration 420 a in response to thearticle 30 being received by theholder 420. For example, the refillingcontrol circuitry 48 may be configured to detect, for example using a sensor or contact electrode such as a connection between theconnectors article 30 has been received by theholder 420, and to operate the motor to slide theholder 420 into theclosed configuration 420 a in response to detecting that thearticle 30 has been received by theholder 420. Alternatively, the refillingcontrol circuitry 48 may detect that thearticle 30 has been received by theholder 420, but operate the motor in response to an input by a user of therefilling device 40, for example via an input means such as a button, touch screen or switch. The refillingcontrol circuitry 48 may be configured to provide a prompt to the user, for example by illuminating an indicator light, displaying a notification on a display screen or playing a sound, to provide the input on the input means. - Equally, the refilling
control circuitry 48 can be configured to operate the motor to slide theholder 420 to theopen configuration 420 b in response to the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30. The refillingcontrol circuitry 48 may be configured to detect that the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30 is complete and to operate the motor in response to detecting that the transfer of aerosol-generatingmaterial 52 is complete. Alternative, as described above, the refillingcontrol circuitry 48 may detect that the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30 is complete, but operate the motor in response to an input by a user of therefilling device 40, for example via an input means such as a button, touch screen or switch. The refillingcontrol circuitry 48 may be configured to provide a prompt to the user, for example by illuminating an indicator light, displaying a notification on a display screen or playing a sound, to provide the input on the input means. - Where the
device interface 49 comprises a biasing means, having placed thearticle 30 into theholder 420, the user can push theholder 420, for example on theouter surface 421, to overcome the biasing means and slide theholder 420 from theopen configuration 420 b to theclosed configuration 420 a, where the retaining mechanism retains theholder 420 in theclosed configuration 420 a. In response to detecting that the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30 is complete, the refillingcontrol circuitry 48 can be configured to release the retaining mechanism such that the biasing means slides theholder 420 from theclosed configuration 420 a to theopen configuration 420 b. Alternatively, the refillingcontrol circuitry 48 may detect that the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30 is complete, but release the retaining mechanism in response to an input by a user of therefilling device 40, for example via an input means such as a button, touch screen or switch. The refillingcontrol circuitry 48 may be configured to provide a prompt to the user, for example by illuminating an indicator light, displaying a notification on a display screen or playing a sound, to provide the input on the input means. In response to the user providing an input on the input means, the refillingcontrol circuitry 48 can be configured to release the retaining mechanism, such that the biasing means slides theholder 420 from theclosed configuration 420 a to theopen configuration 420 b. Alternatively, the input means can be mechanically connected to the retaining mechanism, such that the user input directly releases the retaining mechanism. - As described above, the refilling
control circuitry 48 is further configured to operate an indicator light on therefilling device 40 based on the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30. For example, the refillingcontrol circuitry 48 can be configured to operate the indicator light to provide one or more of the prompts to user as described above, such as to notify the user that thearticle 30 has been received by theholder 420, thereservoir 50 has been received by thereservoir interface 46 and/or that the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30 is beginning, in progress, and/or complete.FIGS. 6A and 6B illustrate indicator light arrangements for arefilling device 40, such as the refillingdevice 40 illustrated inFIGS. 5A and 5B . - The indicator light 423 illustrated in
FIG. 6A is located on thearticle interface 42, in particular on theouter surface 421 of theholder 420 of thearticle interface 42. By locating theindicator light 423 on theouter surface 421, theindicator light 423 can be seen by the user when theholder 420 is in both theopen configuration 420 b and theclosed configuration 420 a. Although theindicator light 423 is illustrated inFIG. 6A as being a rectangle located in the middle of theouter surface 421, it will be appreciated that theindicator light 423 may to located anywhere on theouter surface 421 and be a size and shape such that theindicator light 423 provides one or more of the prompts to user as described above. -
FIG. 6B illustrates an alternative arrangement ofindicator light 423. The indicator light 423 inFIG. 6B is located on thehousing 400 of therefilling device 40, in particular surrounding thearticle opening 422. In other words, theindicator light 423 extends around the perimeter of the article opening 422 such that theindicator light 423 can be seen by the user when theholder 420 is in both theopen configuration 420 b and theclosed configuration 420 a, since theindicator light 423 will extend around the perimeter of the article opening 422 adjacent to theouter surface 421 of theholder 420 when theholder 420 is in theclosed configuration 420 a. It will be appreciated, however, that theindicator light 423 may be located on another surface of the refilling device, such as thesecond surface 420. Locating theindicator light 423 on or proximate to thearticle interface 42 makes it clear to the user that the prompt or notification provided by theindicator light 423 relates to the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30, and more specifically to thearticle interface 42 and/or thearticle 30. -
FIGS. 7A and 8B are schematic diagrams of example reservoirs for use with arefilling device 40, such as the refilling device illustrated inFIGS. 5, 6, 8 and 9 . As described above, thereservoir 50 comprises aerosol-generating material 52 (not illustrated) for transferring, by the refillingdevice 40, to thearticle 30 in order to refill or replenish the aerosol-generatingmaterial 32 in the aerosol-generatingmaterial storage area 39 of thearticle 30. - The
reservoir 50 illustrated inFIGS. 7A and 7B comprises a first, or bottom, end 510 of thereservoir 50 and a second, or top, end 520 of thereservoir 50. Thesecond end 520 is opposite thefirst end 510, such that a major axis or length of thereservoir 50 extends between thefirst end 510 and thesecond end 520. - The
reservoir outlet 55 on thereservoir 50 illustrated inFIGS. 7A and 7B is located at thefirst end 510 of thereservoir 50. When thereservoir 50 is received by the refillingdevice 40, the reservoir is oriented such that thereservoir outlet 55 is located at the bottom or lowest point on thereservoir 50, thereby allowing the transfer ofaerosol generating material 52 from thereservoir 50 to be assisted by gravity. - The
reservoir 50 illustrated inFIGS. 7A and 7B comprises aflange 530 at the top orsecond end 520 of thereservoir 50. In other words, theflange 530 is on the opposite side of thereservoir 50 to thereservoir outlet 55. Theflange 530 is surface that extrudes outwards from the main body or casing 500 of thereservoir 50, providing a means of connecting thereservoir 50 to therefilling device 40 as described in more detail below with respect toFIGS. 8A and 8B . - The
reservoir 50 illustrated inFIGS. 7A and 7B also comprises ahold 540 to allow the user to easily grip and hold thereservoir 50. As illustrated inFIGS. 7A and 7B , thehold 540 is located on a sidewall of thereservoir 50 between thefirst end 510 and thesecond end 520. InFIG. 7A , the hold comprises aflexible tab 540. Thetab 540 is configured to lie flush against thebody 500 of the reservoir 50 (in other words, against the sidewall of the reservoir 50) when the tab is not being used by the user to hold thereservoir 50. This reduces the volume of thereservoir 50 when thetab 540 is not being used. InFIG. 7B , the hold comprises an integral finger which forms part of thebody 500 of thereservoir 50, in particular the sidewall of the reservoir. This provides a solid, rigid surface for the user to hold. - The
reservoir 50 also comprises (not illustrated)reservoir control circuitry 58 configured to control thereservoir 50 and store parameters and/or data associated with thereservoir 50. The parameters associated with thereservoir 50 may include, for example data indicative of an amount of aerosol-generatingmaterial 52 stored in thereservoir 50, data relating to the aerosol-generatingmaterial 52 stored in thereservoir 50, such as one or more ingredients, the concentration and/or amount of the ingredients and/or one or more flavorants within the aerosol-generatingmaterial 52. The data may also comprise an identifier, such as a serial number and/or SKU for thereservoir 50 or other means of identifying thereservoir 50 and/or the type of thereservoir 50, and a date of manufacture and/or expiry of thereservoir 50. As described above in relation to thedevice control circuitry 28, thereservoir control circuitry 58 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. For example, thereservoir control circuitry 58 may comprise a microcontroller unit (MCU) or a system on chip (SoC). Alternatively, thereservoir control circuitry 58 may comprise a code printed onto the reservoir, such as a barcode or QR code, or an NFC chip or other form of passive tag. - The
reservoir 50 illustrated inFIGS. 7A and 7B also comprises one ormore connectors 51 electrically coupled to thereservoir control circuitry 58. Theconnectors 51 are configured to mate with theconnectors 47 on thereservoir interface 46 when thereservoir 50 is received by the refillingdevice 40, thereby allowing power to be supplied from the refillingdevice 40 to thereservoir control circuitry 58 and electrical signals to be transferred between the refillingcontrol circuitry 48 and thereservoir control circuitry 58. As illustrated inFIGS. 7A and 7B , theconnectors 51 are located on the opposite side of thereservoir 50 to thehold 540, between thefirst end 510 and thesecond end 520. In other words, theconnectors 51 are on the side of thereservoir 50 corresponding to the negative z-direction inFIGS. 7A and 7B , whilst thehold 540 is located on the side of thereservoir 50 corresponding to the positive z-axis inFIGS. 7A and 7B . This allows the user to holdreservoir 50 without touching or damaging theconnector 51. - The
reservoir 50 can have a volume of 10 ml or more, for example 20 ml, 50 ml or 100 ml. In other words, the reservoir is configured to contain 10 ml or more of aerosol-generatingmaterial 52 when thereservoir 50 is filled withaerosol generating material 52. Thereservoir interface 46 of therefilling device 40 is then configured to receive areservoir 50 with a volume of 10 ml or more. - The
reservoir 50 can also have a larger volume than thearticle 30. For example, the volume of the reservoir can be at least 5 times greater than the volume of the article, for example times, 20 times or 50 times greater. In other words, the reservoir is configured to contain, when filled with aerosol-generatingmaterial 52, a volume of aerosol-generatingmaterial 52 at least 5 times greater than the aerosol-generatingmaterial storage area 39 of thearticle 30. This allows thesame reservoir 50 to be used to refill the article at least 5 times. Thereservoir interface 46 of therefilling device 40 is then configured to receive areservoir 50 with a volume at least 5 times greater than a volume of the article thearticle interface 42 of therefilling device 40 is configured to receive. - Although not illustrated, the
reservoir 50 may also comprise a window on a sidewall of thereservoir 50 to allow the user to see the amount of aerosol-generatingmaterial 52 contained in thereservoir 50. Alternatively, a portion of a sidewall of thereservoir 50 may be transparent to allow the user to see through the sidewall to see the amount of aerosol-generatingmaterial 52 contained in thereservoir 50. -
FIGS. 8A and 8B are further schematic diagrams of therefilling device 40 illustrated in Figured 5A and 5B, such that the features and operation of therefilling device 40 described above with reference toFIGS. 5 to 6 , in particular thearticle interface 42, are also present but not necessarily illustrated in therefilling device 40 illustrated inFIGS. 8A and 8B . The same reference signs have been used for like elements between the refillingdevice 40 illustrated inFIGS. 5 and 6 and therefilling device 40 illustrated inFIGS. 8A and 8B . - As illustrated in
FIGS. 8A and 8B , thereservoir interface 46 is located on a different side of therefilling device 40 to thearticle interface 42. The article interface 42 (as described above with reference toFIGS. 5A and 5B ) is on a side of therefilling device 40 corresponding to the positive x-direction inFIGS. 8A and 8B , whilst thereservoir interface 46 is located on a side of therefilling device 40 corresponding to the positive z-direction inFIGS. 8A and 8B . In other words, thereservoir interface 46 and thearticle interface 42 are orthogonal to each other. Alternatively, thereservoir interface 46 and thearticle interface 42 could be opposite each other on therefilling device 40. For example, thearticle interface 42 could be on a side of therefilling device 40 corresponding to the negative z-direction inFIGS. 8A and 8B , whilst thereservoir interface 46 is located on a side of therefilling device 40 corresponding to the positive z-direction inFIGS. 8A and 8B . - As described above with reference to
FIGS. 5A and 5B , thereservoir interface 46 illustrated inFIGS. 8A and 8B is located above thearticle interface 42. Thereservoir interface 46 illustrated inFIGS. 8A and 8B comprises aholder 460 configured to receive thereservoir 50. Theholder 460 is a size and shape that corresponds to the size, depth and shape of at least a portion of thereservoir 50 such that at least a portion of thereservoir 50 can be inserted into theholder 460 in order for thereservoir 50 to be received by thereservoir interface 46. For example, the reservoirs illustrated inFIGS. 7A and 7B comprises aflange 530 at a top orsecond end 520 of thereservoir 50. In this case, theholder 460 can comprise rails or other guides to receive theflange 530 of thereservoir 50. In other words, theflange 530 of the reservoir can be slid onto or into rails on theholder 460 so that theflange 530 of thereservoir 50 rests in or on theholder 460 when thereservoir 50 is received by theholder 460. - The
reservoir interface 46 illustrated inFIGS. 8A and 8B also comprises aretaining mechanism 461 configured to retain thereservoir 50 in theholder 460. Theretaining mechanism 461 may be a latch, clip, spring clip, or other retaining means suitable to hold and retain thereservoir 50 in theholder 460. Theretaining mechanism 461 is illustrated inFIGS. 8A and 8B as being located on theholder 460, but it will be appreciated that theretaining mechanism 461 can be located anywhere on thereservoir interface 46 in order to retain and hold thereservoir 50 in theholder 460. - The
holder 460 illustrated inFIGS. 8A and 8B comprises one ormore connectors 47, such as contact electrodes, connected via electrical wiring to therefilling control circuitry 48 to facilitate communication between the refillingcontrol circuitry 48 and thereservoir control circuitry 58; theconnectors 51 on thereservoir 50 mate with theconnectors 47 on theholder 460 when thereservoir 50 is received by theholder 460, thereby allowing power to be supplied from the refillingdevice 40 to thereservoir control circuitry 58 and electrical signals to be transferred between the refillingcontrol circuitry 48 and thereservoir control circuitry 58. Theconnectors 47 may be arranged relative to theholder 460 in a pattern and position matching/mirroring theconnectors 51 on thereservoir 50 in order to facilitate the mating of theconnectors 51 on thereservoir 50 and theconnectors 47 on theholder 460 when thereservoir 50 is received by theholder 460. Alternatively theconnectors 47 may be located elsewhere on thereservoir interface 46 provided that theconnectors 51 on thereservoir 50 mate with theconnectors 47 when thereservoir 50 is received by theholder 460. - The
holder 460 is also configured such that thereservoir outlet 55 on thereservoir 50 is located proximate to the refillinginlet 45 when thereservoir 50 is received by theholder 460. This allows the refillinginlet 45 to mate with areservoir outlet 55 during the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30. In other words, theholder 460 is a size and shape such when thereservoir 50 is located in theholder 460 and retained by theretaining mechanism 461, thereservoir outlet 55 on thereservoir 50 is located proximate to the refillinginlet 45. - The
holder 460 may be a size and shape such that thereservoir 50 can only be received by theholder 460 in one orientation, such thatreservoir outlet 55 on thereservoir 50 is located proximate to the refillinginlet 45 and theconnectors 51 on thereservoir 50 mate with theconnectors 47 on theholder 460 when thereservoir 50 is received by the holder 460 (i.e. thereservoir 50 is located in theholder 460 and retained by the retaining mechanism 461). - The
holder 460 is configured to receive thereservoir 50 in a horizontal direction (along the x-axis inFIG. 5B ) when therefilling device 40 is located on a horizontal surface (i.e. when theflat surface 410 is aligned such that theflat surface 410 is substantially horizontal). As will be appreciated by comparingFIGS. 7A and 7B withFIGS. 8A and 8B , theholder 460 is configured to receive thereservoir 50 such that thereservoir outlet 55 is located at the lowest point of thereservoir 50. In other words, when thereservoir 50 is received by theholder 460, thereservoir outlet 55 is the closest point on thereservoir 50 to theflat surface 410 of the refilling device. As described above, this allows the transfer ofaerosol generating material 52 from thereservoir 50 to be assisted by gravity. - The
reservoir interface 46 illustrated inFIGS. 8A and 8B is located within areservoir opening 462 in thehousing 400 of therefilling device 40. In other words, thereservoir interface 46 is contained within and/or enclosed by thehousing 400 of therefilling device 40 such that thereservoir interface 46 is configured enclose thereservoir 50 inside thehousing 400 of therefilling device 40 during the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to the article - The
housing 400 illustrated inFIGS. 8A and 8B comprises an access panel 463. The access panel 463 is configured to move between anopen configuration 463 b and aclosed configuration 463 a. -
FIG. 8A illustrates the access panel 463 in theclosed configuration 463 a. When the access panel 463 in theclosed configuration 463 a, thereservoir opening 462 is sealed by the access panel 463. In other words, when the access panel 463 is in theclosed configuration 463 a, thereservoir interface 46 is enclosed and sealed within thehousing 400 such that thereservoir 50 cannot be removed or inserted into thereservoir interface 46. The refillingcontrol circuitry 48 is then configured to facilitate the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30 with the access panel 463 is in theclosed configuration 463 a. As illustrated inFIG. 8A , anouter surface 464 of the access panel 463 is flush with or proximate to the second ortop surface 420 of thehousing 400 when the access panel 463 in theclosed configuration 463 a, such that the access panel 463 substantially confirms to the shape of thehousing 400, thereby forming a portion of thehousing 400. - The refilling
control circuitry 48 may be configured to detect, for example using a sensor or contact electrode, when the access panel 463 is in theclosed configuration 463 a, and to facilitate the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30 in response to detecting that the access panel 463 is in theclosed configuration 463 a. Alternatively, the refillingcontrol circuitry 48 may detect that the access panel 463 is in theclosed configuration 463 a, but only facilitate the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30 to an input by a user of therefilling device 40, for example via an input means such as a button, touch screen or switch. Transferring aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30 when the access panel 463 is in theclosed configuration 463 a ensures that thereservoir interface 46 encloses thereservoir 50 inside thehousing 400 of therefilling device 40 during the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30. This prevents the user from touching, interfering with or removing thereservoir 50 during the transfer of aerosol-generatingmaterial 52, thereby improving the safety of the transfer and refilling process. -
FIG. 8B illustrates the access panel 463 in theopen configuration 463 b. In the open configuration, the access panel 463 does not seal or cover thereservoir opening 462. In other words, thehousing 400 of therefilling device 40 does not fully enclose thereservoir interface 46. Thereservoir opening 462 therefore provides a gap or hole in thehousing 400 of therefilling device 40 through which thereservoir interface 46 can be accessed. Accordingly, thereservoir interface 46 is configured to receive thereservoir 50 when the access panel 463 is in theopen configuration 463 b. - As illustrated in
FIG. 8B , the access panel 463 is displaced upwards along the y-axis (along the major axis of the refilling device 40), such that theouter surface 464 of the access panel 463 is not flush with or proximate to the second ortop surface 420 of thehousing 400 when the access panel 463 in theopen configuration 463 b. As described above with reference toFIGS. 5A and 5B , theholder 420 of thearticle interface 42 is configured to slide between anopen configuration 420 b and aclosed configuration 420 a. Theholder 420 is configured to slide a horizontal direction aligned with the x-axis when therefilling device 40 is located on a horizontal surface (i.e. when the first end andflat surface 410 are placed or otherwise located on a horizontal surface aligned with x-axis inFIGS. 5A and 5B ). As illustrated inFIGS. 8A and 8B , the access panel 463 moves between theopen configuration 463 b and theclosed configuration 463 a in a vertical direction aligned with the y-axis when therefilling device 40 is located on a horizontal surface (i.e. when the first end andflat surface 410 are placed or otherwise located on a horizontal surface aligned with x-axis inFIGS. 8A and 8B ). Accordingly, theholder 420 slides in a direction perpendicular to the direction the access panel 463 moves between theopen configuration 463 a and theclosed configuration 463 b. - The access panel 463 illustrated in
FIGS. 8A and 8B is a sliding panel that slides between theopen configuration 463 a and theclosed configuration 463 b. For example, the access panel 463 and a portion of therefilling device 40 may comprise rails and corresponding grooves to allow the access panel 463 to side in a planar fashion (e.g. along the y-axis as illustrated inFIGS. 8A and 8B ). - The access panel 463 illustrated in
FIGS. 8A and 8B extends around substantially part of or substantially all of the perimeter of thehousing 400 of therefilling device 40. In other words, the access panel 463 is partial or complete tube that slides around and along the outside of thehousing 400 of therefilling device 40. The access panel 463 may extend around half of thehousing 400, 75% of thehousing 400 or the entirety of thehousing 400. It will be appreciated, however, that the access panel 463 may extend around any portion of the housing such that the access panel 463 seals thereservoir opening 462 when the access panel 463 is in theclosed configuration 463 a and access panel 463 opens or otherwise exposes thereservoir opening 462 when the access panel 463 is in theopen configuration 463 b. - The access panel 463 may comprise a window, for example at a location that is proximate to the
reservoir opening 462 when the access panel 463 is in theclosed configuration 463 b. This allows the user to see through the access panel 463 and thereservoir opening 462 to observe the reservoir and the refilling process. Alternatively, a portion of the access panel 463 at a location that is proximate to thereservoir opening 462 when the access panel 463 is in theclosed configuration 463 b may be transparent to allow the user to see through the access panel 463 and thereservoir opening 462 to observe the reservoir and the refilling process. - As described above, the
reservoir interface 46 is configured to receive thereservoir 50 when the access panel 463 is in theopen configuration 463 b. Thereservoir 50 is received by theholder 460 and theretaining mechanism 461 retains thereservoir 50 in theholder 460. In order to remove thereservoir 50 from thereservoir interface 46, the user may be able to pull on a surface of thereservoir 50, such as thehold 540, in order to provide a force to overcome theretaining mechanism 461. For example, where theretaining mechanism 461 is a spring clip, pulling on thehold 540 of thereservoir 50 will provide sufficient force to overcome the retaining force of the spring clip and to remove thereservoir 50 from thereservoir interface 46. Alternatively, the refillingcontrol circuitry 48 is configured to release the retaining mechanism, for example in response to the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30, or in response to a user input on an input means. Where theretaining mechanism 461 is a latch, thereservoir 50 may only be removable from thereservoir interface 46 in response to the latch being released, either by the refillingcontrol circuitry 48 or through actuation by the user of a switch or button mechanical linked to the latch. - The
holder 460 is configured to receive thereservoir 50 such that thehold 540 is located proximate and/or is the closest point on the reservoir to thereservoir opening 462, thereby allowing the user to grip and pull on thehold 540 in order to remove thereservoir 50 from theholder 460. - A motor may be connected to the access panel 463, with the refilling
control circuitry 48 configured to operate the motor to move the access panel 463 between theopen configuration 463 b and theclosed configuration 463 a. Alternatively, the access panel 463 may comprise a biasing means, such as a spring, configured to bias the access panel 463 towards theopen configuration 463 b. A force then needs to be applied on the access panel 463 to overcome the biasing means and move the access panel 463 to theclosed configuration 463 a. In this case, there may be a latch, clip or other retaining means to hold the access panel 463 in theclosed configuration 463 a. - The access panel 463 may be configured to move between the
open configuration 463 b and theclosed configuration 463 a in response to an input on therefilling device 40 by a user of therefilling device 40. For example, where the access panel 463 comprises a motor, the refillingdevice 40 may comprise input means such as a button, touch screen or switch. In response to the user providing an input on the input means, the refillingcontrol circuitry 48 can be configured to operate the motor to move the access panel 463 from theopen configuration 463 b to theclosed configuration 463 a. The refillingcontrol circuitry 48 can be configured to operate the motor to move the access panel 463 from theclosed configuration 463 a to theopen configuration 463 b in response to a further input from the user, either on the input means via a different input means. - Where the access panel 463 comprises a biasing means, in response to the user providing an input on the input means, the refilling
control circuitry 48 can be configured to release the retaining means, thereby allowing the biasing means to more theclosed configuration 463 a to theopen configuration 463 b. Alternatively, the input means can be mechanically connected to the retaining mechanism, such that the user input directly released the retaining means. The user can then push the access panel 463, for example on theouter surface 464, to overcome the biasing means and return the access panel 463 from theopen configuration 463 b to theclosed configuration 463 a, where the retaining means retains the access panel 463 in theclosed configuration 463 a. - In each case, the input means may be located on the
housing 400 of the refilling device proximate to the access panel 463, or on a different location on therefilling device 40. Alternatively, the input means may be located on the access panel 463, such as on the outer surface 494 of the access panel 463 or a surface of the access panel 463 proximate to the reservoir opening when the access panel 463 is in theclosed configuration 463 a. -
FIGS. 9A and 9B are schematic diagrams of arefilling device 40 for an article of an aerosol provision system, such as thearticle 30 illustrated inFIG. 2 orFIG. 4 , and thereservoir 50 illustrated inFIG. 3 orFIGS. 7A and 7B . - The refilling
device 40 illustrated inFIGS. 9A and 9B is substantially the same as the refillingdevice 40 illustrated inFIGS. 5, 6 and 8 , such that the features and operation of therefilling device 40 described above with reference toFIGS. 5, 6 and 8 are also present, but not necessarily illustrated, in therefilling device 40 illustrated inFIGS. 9A and 9B . The same reference signs have been used for like elements between the refillingdevice 40 illustrated inFIGS. 5, 6 and 8 and therefilling device 40 illustrated inFIGS. 9A and 9B . - In addition to the features described above with reference to
FIGS. 5 to 8 , the refillingdevice 40 illustrated inFIGS. 9A and 9B includes adevice interface 49. As described above with reference toFIG. 3 , thedevice interface 49 configured to receive theaerosol provision device 20. Control circuitry, such as the refillingcontrol circuitry 48 described above, is then configured to transfer electrical power to theaerosol provision device 20 for charging apower source 14 of theaerosol provision device 20. For example, thecontrol circuitry 48 may be configured to charge apower source 14 of theaerosol provision device 20 in response to theaerosol provision device 20 being received by thedevice interface 49. -
FIG. 9A illustrates thedevice interface 49 at afirst location 49 a. When thedevice interface 49 is at thefirst location 49 a, thedevice interface 49 is located within thehousing 400 of therefilling device 40. In other words, thedevice interface 49 is contained within and/or enclosed by thehousing 400 of therefilling device 40 such that theaerosol provision device 20 cannot received by thearticle interface 49. This protects the components of thedevice interface 49 when thedevice interface 49 is not in use. - As illustrated in
FIG. 9A , anouter surface 491 of thearticle interface 49 may lie flush with thehousing 400 when thedevice interface 49 at afirst location 49 a such that theouter surface 491 of thearticle interface 49 substantially confirms to the shape of thehousing 400, thereby forming a portion of thehousing 400. -
FIG. 9B illustrates thedevice interface 49 at asecond location 49 b. When thedevice interface 49 is at thesecond location 49 a, thedevice interface 49 at least partially located outside thehousing 400 of therefilling device 40. In other words, at least a portion of thedevice interface 49 is not enclosed or contained within thehousing 400 when thedevice interface 49 is at thesecond location 49 a. As illustrated inFIG. 9B , theouter surface 491 of thedevice interface 49 is displaced away from thehousing 400 along the z-axis, such that theouter surface 491 is not flush with thehousing 400 when thedevice interface 49 is at thesecond location 49 a. - As illustrated in
FIG. 9B , thedevice interface 49 is located on a different side of the refilling device to thearticle interface 42. The article interface 42 (as described above with reference toFIGS. 5A and 5B ) is on a side of therefilling device 40 corresponding to the positive x-direction inFIG. 9B , whilst thedevice interface 49 is located on a side of the refilling device corresponding to the positive z-axis inFIG. 9B . In other words, thedevice interface 49 and thearticle interface 42 are orthogonal to each other. Alternatively, thedevice interface 49 and thearticle interface 42 could be opposite each other on therefilling device 40. For example, thearticle interface 42 could be on a side of therefilling device 40 corresponding to the negative z-direction inFIG. 9B , whilst thedevice interface 49 is located on a side of therefilling device 40 corresponding to the positive z-axis inFIG. 9B . - As illustrated in
FIG. 9B , thedevice interface 49 is located on the same different side of therefilling device 40 to thereservoir interface 46. Alternatively, thedevice interface 49 and thereservoir interface 46 could be opposite each other on therefilling device 40, such that each of thearticle interface 42, thereservoir interface 46 and thedevice interface 49 are located on different sides of therefilling device 40. - The
device interface 49 is configured to slide between thefirst location 49 a and thesecond location 49 b. For example, thedevice interface 49 and a portion of the refilling device may comprise rails and corresponding grooves to allow thedevice interface 49 to side in a planar fashion (e.g. along the z-axis as illustrated inFIGS. 9A and 9B ). - A motor may be connected to the
device interface 49, with the refillingcontrol circuitry 48 configured to operate the motor to move thedevice interface 49 between thefirst location 49 a and thesecond location 49 b. Alternatively, thedevice interface 49 may comprise a biasing means, such as a spring, configured to bias thedevice interface 49 towards thesecond location 49 b. A force then needs to be applied on thedevice interface 49 to overcome the biasing means and move thedevice interface 49 to thefirst location 49 a. In this case, there may be a latch, clip or other retaining mechanism to hold thedevice interface 49 in thefirst location 49 a. - The
device interface 49 may be configured to slide from thefirst location 49 a to thesecond location 49 b in response to an input on therefilling device 40 by a user of therefilling device 40. For example, where thedevice interface 49 comprises a motor, the refillingdevice 40 may comprise input means such as a button, touch screen or switch. In response to the user providing an input on the input means, the refillingcontrol circuitry 48 can be configured to operate the motor to move thedevice interface 49 from thefirst location 49 a to thesecond location 49 b. The refillingcontrol circuitry 48 can be configured to operate the motor to move thedevice interface 49 from thesecond location 49 a to thefirst location 49 b in response to a further input from the user, either on the input means via a different input means. - Where the
device interface 49 may comprise a biasing means, in response to the user providing an input on the input means, the refillingcontrol circuitry 48 can be configured to release the retaining mechanism, thereby allowing the biasing means to more thedevice interface 49 from thefirst location 49 a to thesecond location 49 b. Alternatively, the input means can be mechanically connected to the retaining mechanism, such that the user input directly released the retaining mechanism. The user can then push thedevice interface 49, for example on theouter surface 491, to overcome the biasing means and return thedevice interface 49 from the second location to the first location, where the retaining mechanism retains thedevice interface 49 in thefirst location 49 a. - In each case, the input means may be located on the
housing 400 of the refilling device proximate to thedevice interface 49, or on a different location on therefilling device 40. Alternatively, the input means may be located on the device interface, such as on theouter surface 491 of thedevice interface 49. - As illustrated in
FIG. 9B , thedevice interface 49 is configured to receive theaerosol provision device 20 at thesecond location 49 b. Thedevice interface 49 illustrated inFIG. 9B comprises arecess 492 configured to receiveaerosol provision device 20. Therecess 492 is a size and shape that corresponds to the size, depth and shape of a portion of theaerosol provision device 20 such that a portion of theaerosol provision device 20 can be inserted into therecess 492 in order for theaerosol provision device 20 to be received by thedevice interface 49. The recess then secures and retains theaerosol provision device 20 in place. - The
device interface 49 illustrated inFIG. 9B also comprises one ormore connectors 493, such as contact electrodes, connected via electrical wiring to therefilling control circuitry 48. Theconnectors 493 are arranged relative to therecess 492 and thedevice interface 49 in a pattern and position matching/mirroring connectors on the portion of the aerosol provision device in order to facilitate the mating of theconnectors 26 on theaerosol provision device 20 and theconnectors 493 on thedevice interface 49 when theaerosol provision device 20 is received by thedevice interface 49. For example, theconnector 493 on thedevice interface 49 may correspond to a USB-C, mini or micro USB male connector, with theconnector 26 on theaerosol provision device 20 corresponding to the equivalent USB-C, mini or micro USB female connector. As illustrated inFIG. 8B , the connector on theaerosol provision device 20 is located on an end of theaerosol provision device 20 opposite the end of the aerosol provision device where theinterface 24 is located. Alternatively, the connector on theaerosol provision device 20 that mates with theconnector 493 on thedevice interface 49 may be located on any surface of theaerosol provision device 20 other than the end or surface where theinterface 24 with thearticle 30 is located. - As illustrated in
FIG. 9B , thedevice interface 49 is configured to receive theaerosol provision device 20 in a vertical orientation when therefilling device 40 is located on a horizontal surface. As described above, the refillingdevice 40 has aflat surface 410 to facilitate storage of the desktop refilling device on another flat surface. As illustrated inFIG. 9B , theflat surface 410 can be aligned such that the flat surface is substantially horizontal (in the x-z plane in FIG. 9B). Thedevice interface 49 is then configured to receive the aerosol provision device in a vertical direction (in other words, a direction perpendicular to the flat surface 410). InFIG. 9B , therecess 492 of thedevice interface 49 is located in the same x-z plane as theflat surface 410, but on the opposite side of therefilling device 40; in other words, theflat surface 410 is on the negative y side of therefilling device 40 whilst therecess 492 of thedevice interface 49 is located on the positive y side of the refilling device. This allows theaerosol provision device 20 to be received by thedevice interface 49 from above by lowering theaerosol provision device 20 downwards onto thedevice interface 49, into the recess 492 (in other words, in the negative y direction). - By comparing
FIGS. 5A and 5B withFIGS. 9A and 9B , it will also be appreciated that thedevice interface 49 inFIG. 8B is configured to receive theaerosol provision device 20 in an orientation or direction perpendicular to an orientation or direction in which thearticle interface 42 is configured to receive thearticle 30. As described above in reference toFIGS. 5A and 5B , thearticle interface 42 is configured to receive thearticle 30 in a horizontal orientation when therefilling device 40 is located on a horizontal surface; this direction corresponds to the x-axis inFIGS. 5A, 5B, 9A and 9B . In contrast, thedevice interface 49 is configured to receive theaerosol provision device 20 in a vertical orientation when therefilling device 40 is located on a horizontal surface; this direction corresponds to the y-axis inFIGS. 5A, 5B, 9A and 9B . Accordingly, thedevice interface 49 illustrated inFIG. 9A and 9B is configured to receive theaerosol provision device 20 in an orientation or direction perpendicular to an orientation or direction in which thearticle interface 42 is configured to receive thearticle 30. - As described above, the refilling
control circuitry 48 of the refilling device is configured to facilitate the transfer of aerosol-generatingmaterial 52 from areservoir 50 to anarticle 30. For example, the refillingcontrol circuitry 48 can facilitate the transfer of aerosol-generatingmaterial 52 from areservoir 50 to anarticle 30 in response to detecting that thearticle 30 has been received by the refillingdevice 40. As described above, the refillingcontrol circuitry 48 can be configured to detect that thearticle 30 has been received by thearticle interface 42, such as by detecting theconnectors 31 on thearticle 30 mating with theconnectors 41 on the refilling device when thearticle 30 is received by thearticle interface 42. As described above, the refillingcontrol circuitry 48 may additionally detect that anarticle 30 has been received by aholder 420 of thearticle interface 42, and that the holder is in a closed configuration before facilitating the transfer of aerosol-generatingmaterial 52 from areservoir 50 to anarticle 30. - The refilling
control circuitry 48 is further configured to determine an amount of aerosol generating material in thearticle 30 in response to detecting that thearticle 30 has been received by the refillingdevice 40. As described above, the refillingcontrol circuitry 48 can be configured to communicate witharticle control circuitry 38 in thearticle 30. The refillingcontrol circuitry 48 can therefore determine an amount of aerosol generating material in thearticle 30 by communicating with thearticle control circuitry 38 and receiving an indication of the amount of aerosol generating material in thearticle 30 from thearticle control circuitry 38. Alternatively, the refillingdevice 40 may comprise a sensor, such as a light, capacitive or ultrasonic sensor configured to detect the amount of aerosol generating material in thearticle 30. The refillingcontrol circuitry 48 can control the sensor to detect the amount of aerosol generating material in thearticle 30 in response to detecting that thearticle 30 has been received by the refillingdevice 40, and then determine the amount of aerosol generating material in thearticle 30 based on data received from the sensor. - The refilling
control circuitry 48 is then configured to facilitate the transfer ofaerosol generating material 52 from thereservoir 50 to thearticle 30 in response to determining that the amount of aerosol generating material in thearticle 30 is less that an article threshold. As will be appreciated, thearticle 30 need only be refilled with aerosol generating material when there is little or no aerosol generating material remaining in thearticle 30. The article threshold is therefore set to ensure that the transfer ofaerosol generating material 52 from thereservoir 50 to the article is not attempted when there is already a sufficient amount of aerosol generating material in thearticle 30. For example, the article threshold may correspond to half of the capacity or volume of the aerosol-generatingmaterial storage area 39 of thearticle 30, or correspond to less than half capacity of the aerosol-generatingmaterial storage area 39, such as a quarter or a sixth. If the amount of aerosol generating material in the article is greater than the article reservoir threshold, then it is not possible to facilitate the transfer ofaerosol generating material 52, and the refillingcontrol circuitry 48 may be configured to provide a notification to the user. - The amount of
aerosol generating material 52 transferred from thereservoir 50 to thearticle 30 can be based on the amount of aerosol generating material in thearticle 30. For example, the refillingcontrol circuitry 48 can be configured to determine the amount of capacity or volume of the aerosol-generatingmaterial storage area 39 of the article, for example by communicating with thearticle control circuitry 38. The refillingcontrol circuitry 48 is then configured to facilitate the transfer of an amount ofaerosol generating material 52 from thereservoir 50 to thearticle 30 such that the aerosol-generatingmaterial storage area 39 of thearticle 30 is full or at capacity with aerosol generating material. In other words, the amount ofaerosol generating material 52 transferred from thereservoir 50 to thearticle 30 corresponds to the difference between the capacity or volume of the aerosol-generatingmaterial storage area 39 of thearticle 30 and the amount of aerosol generating material in thearticle 30. - The refilling
control circuitry 48 can also be configured to facilitate the transfer of aerosol-generatingmaterial 52 from thereservoir 50 to thearticle 30 in response to detecting that thereservoir 50 has been received by the refillingdevice 40. As described above, the refillingcontrol circuitry 48 can be configured to detect that thereservoir 50 has been received by thereservoir interface 46, such as by detecting theconnectors 51 on thereservoir 51 mating with theconnectors 47 on therefilling device 40 when thereservoir 50 is received by thereservoir interface 46. As described above, the refillingcontrol circuitry 48 may additionally detect that areservoir 50 has been received by aholder 460 of thereservoir interface 46, and that an access panel 463 is in a closed configuration before facilitating the transfer of aerosol-generatingmaterial 52 from areservoir 50 to anarticle 30. - The refilling
control circuitry 48 is further configured to determine an amount ofaerosol generating material 52 in thereservoir 50 in response to detecting that thereservoir 50 has been received by the refillingdevice 40. As described above, the refillingcontrol circuitry 48 can be configured to communicate withreservoir control circuitry 58 in thereservoir 50. The refillingcontrol circuitry 48 can therefore determine an amount of aerosol generating material in thereservoir 50 by communicating with thereservoir control circuitry 58 and receiving an indication of the amount of aerosol generating material in thereservoir 50 from thereservoir control circuitry 58. Alternatively, the refillingdevice 40 may comprise a sensor, such as a light, capacitive or ultrasonic sensor configured to detect the amount ofaerosol generating material 52 in thereservoir 50. The refillingcontrol circuitry 48 can control the sensor to detect the amount of aerosol generating material in thereservoir 50 in response to detecting that thereservoir 50 has been received by the refillingdevice 40, and then determine the amount of aerosol generating material in thereservoir 50 based on data received from the sensor. - The refilling
control circuitry 48 can then be configured to facilitate the transfer ofaerosol generating material 52 from thereservoir 50 to thearticle 30 in response to determining that the amount ofaerosol generating material 52 in thereservoir 50 is greater than a reservoir threshold. The reservoir threshold represents a minimum amount ofaerosol generating material 52 that can be transferred from thereservoir 50 to thearticle 30. If the amount ofaerosol generating material 52 in thereservoir 50 is less than a reservoir threshold, then it is not possible to facilitate the transfer ofaerosol generating material 52, and the refillingcontrol circuitry 48 may be configured to provide a notification to the user. - The amount of
aerosol generating material 52 transferred from thereservoir 50 to thearticle 30 can be based on the amount ofaerosol generating material 52 in thereservoir 50. For example, if the amount ofaerosol generating material 52 in thereservoir 50 is less than an available capacity of the aerosol-generatingmaterial storage area 39 of the article 30 (in other words, if the amount ofaerosol generating material 52 in thereservoir 50 is less than the difference between the capacity of the aerosol-generatingmaterial storage area 39 and the amount of aerosol generating material in the article 30) therefilling control circuitry 48 can be configured to facilitate the transfer of all of theaerosol generating material 52 from thereservoir 50 to thearticle 30. Alternatively, if the amount ofaerosol generating material 52 in thereservoir 50 is less than an available capacity of the aerosol-generatingmaterial storage area 39 of the article 30 (in other words, if the amount ofaerosol generating material 52 in thereservoir 50 is less than the difference between the capacity of the aerosol-generatingmaterial storage area 39 and the amount of aerosol generating material in the article 30), then the refillingcontrol circuitry 48 can be configured to facilitate the transfer of an amount ofaerosol generating material 52 from thereservoir 50 to thearticle 30 corresponding to the available capacity of the aerosol-generatingmaterial storage area 39 of thearticle 30. In other words, the refillingcontrol circuitry 48 is configured to facilitate the transfer ofaerosol generating material 52 from thereservoir 50 to thearticle 30 such that the aerosol-generatingmaterial storage area 39 of thearticle 30 is full of aerosol generating material. - As described above, the refilling
control circuitry 48 can also be configured to transfer electrical power to theaerosol provision device 20 for charging apower source 14 of theaerosol provision device 20 in response to detecting that theaerosol provision device 20 has been received by the refillingdevice 40. The refillingcontrol circuitry 48 may detect that theaerosol provision device 20 has been received by the refillingdevice 40 by detecting theconnectors 26 on theaerosol provision device 20 mating with theconnectors 493 on therefilling device 40 when theaerosol provision device 20 is received by thedevice interface 49. - A described above, a method of refilling an
article 30 of anaerosol provision system 10, performed by arefilling device 40, such as by the refillingcontrol circuitry 48, comprises facilitating the transfer of aerosol-generating material from a reservoir to the article in response to detecting that the article has been received by the refilling device. The method may further comprise any of the steps and operations performed by the refillingdevice 40, and in particular the refillingcontrol circuitry 48 as described herein. The methods may be stored as instructions on a computer readable storage medium, such that when the instructions are executed by a processor, the methods described herein are performed. The computer readable storage medium may be non-transitory. - As described above, the present disclosure relates to (but it not limited to) a desktop refilling device for an article of an aerosol provision system comprising an article interface configured to receive the article, a reservoir interface configured to receive a reservoir, and refilling control circuitry configured to facilitate the transfer of aerosol-generating material from the reservoir to the article, wherein the article interface and/or the reservoir interface are configured to respectively enclose the article and the reservoir inside a housing of the desktop refilling device during the transfer of aerosol-generating material from the reservoir to the article.
