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.

These aspects and other aspects will be apparent from the following detailed description. In this regard, particular sections of the description are not to be read in isolation from other sections.
Embodiments of the disclosure will now be described, by way of example only, with reference to accompanying drawings, in which:
Aspects and features of certain examples and embodiments are discussed/described herein. Some aspects and features of certain examples and embodiments may be implemented conventionally and these are not discussed/described in detail in the interests of brevity. It will thus be appreciated that aspects and features of articles and systems discussed herein which are not described in detail may be implemented in accordance with any conventional techniques for implementing such aspects and features.
The present disclosure relates to aerosol provision systems, which may also be referred to as aerosol provision systems, such as e-cigarettes. Throughout the following description the term “e-cigarette” or “electronic cigarette” may sometimes be used, but it will be appreciated this term may be used interchangeably with aerosol provision system and electronic aerosol provision system.
As noted above, aerosol provision systems (e-cigarettes) often comprise a modular assembly including both a reusable part (aerosol provision device) and a replaceable (disposable) or refillable cartridge part, referred to as an article. Systems conforming to this type of two-part modular configuration may generally be referred to as two-part systems or devices. It is also common for electronic cigarettes to have a generally elongate shape. For the sake of providing a concrete example, certain embodiments of the disclosure described herein comprise this kind of generally elongate two-part system employing refillable cartridges. However, it will be appreciated the underlying principles described herein may equally be adopted for other electronic cigarette configurations, for example modular systems comprising more than two parts, as devices conforming to other overall shapes, for example based on so-called box-mod high performance devices that typically have a more boxy shape.
As described above, the present disclosure relates to (but it not limited to) refilling devices for articles of aerosol provision systems, such as e-cigarettes and electronic cigarettes.
The aerosol provision device 20 and article 30 each comprise an interface 22, 24 such that the aerosol provision device 20 and article 30 are mechanically coupled for use. As described above, the interfaces may comprise a screw thread, bayonet, latched or friction fit fixing, wherein the interface 24 on the aerosol provision device 20 and the interface 24 on the article 30 each comprise a complementary fitting or fixture to enable the aerosol provision device 20 and article
The article 30 comprises or consists of aerosol-generating material 32, part or all of which is intended to be consumed during use by a user. An article 30 may comprise one or more other components, such as an aerosol-generating material storage area 39, an aerosol-generating material transfer component 37, an aerosol generation area, a housing, a wrapper, a mouthpiece a filter and/or an aerosol-modifying agent.
An article 30 may also comprise an aerosol generator 36, such as a heating element, that emits heat to cause the aerosol-generating material 32 to generate aerosol in use. The aerosol generator 36 may, for example, comprise combustible material, a material heatable by electrical conduction, or a susceptor. It should be noted that it is possible for the aerosol generator 36 to be part of the aerosol provision device 20 and the article 30 then may comprise the aerosol-generating material storage area 39 for the aerosol-generating material 32 such that, when the article 30 is coupled with the aerosol provision device 20 via the interfaces 22, 24, the aerosol-generating material 32 can be transferred to the aerosol generator 36 in the aerosol 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-generating material 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-generating material 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 a power source 14, such as a battery, configured to supply electrical power to the aerosol generator 36. The power 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. The battery 14 may be recharged through the charging port (not illustrated), which may, for example, comprise a USB connector.
The aerosol provision device 20 includes device control circuitry 28 configured to control the operation of the aerosol 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, the device control circuitry 28 may comprise power source control circuitry for controlling the supply of electrical power from the power source 14 to the aerosol 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 the device 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 or more air inlets 21. In use, as a user inhales on the mouthpiece 35, air is drawn into the aerosol provision device 20 through the air inlets 21 and along an air channel 23 to the aerosol generator 36, where the air mixes with the vaporized aerosol-generating material 32 and forms a condensation aerosol. The air drawn through the aerosol generator 36 continues along the air channel 23 to a mouthpiece 35, carrying some of the aerosol with it, and out through the mouthpiece 35 for inhalation by the user. Alternatively, the one or more air inlets 21 may be included on the article 30, such that the air channel 23 is entirely contained within the article 30.
By way of a concrete example, the article 30 comprises a housing (formed, e.g., from a plastics material), an aerosol-generating material 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 the aerosol generator 36, and a mouthpiece 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, the mouthpiece 35. The aerosol generator 36 of this example comprises a heater element formed from an electrically resistive material (such as NiCr8020) spirally wrapped around the aerosol-generating material transfer component 37, and located in the air channel 23. The area around the heating element and wick combination is the aerosol-generating area of the article 30.
The article 30 illustrated in
The refilling orifice 34 and/or the refilling tube 33 may be sealable, for example with a cap, one-way valve or septum valve, in order to ensure that aerosol-generating material 32 does not leak out of the refilling orifice 34. In other words, the refilling orifice 34 can comprise a cap, one-way valve or septum valve. Although the refilling orifice 34 is illustrated in

As illustrated in
The refilling device 40 also comprises one or more reservoir interfaces 46 configured to receive a reservoir 50. In the same fashion as described above in relation to the article interface 42, each of the reservoir interfaces 46 may comprise a slot, tray, opening or aperture on the refilling device 40 into or onto which the reservoir 50 is placed or coupled. Alternatively, each reservoir interface 46 may comprise a lead or other cable which is attachable or otherwise connectable to the reservoir 50. Although two reservoir interfaces 46 are illustrated in
As illustrated in
The refilling device 40 also comprises refilling control circuitry 48 configured to control the operation of the refilling device 40. In particular, the refilling control circuitry 48 is configured to facilitate the transfer of aerosol-generating material 52 from a reservoir 50 to the article 30. As described above in relation to the device control circuitry 28, the refilling control 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 refilling control circuitry 48 may comprise a microcontroller unit (MCU) or a system on chip (SoC).
The refilling device 40 also comprises a housing 400 which contains and encloses the components of the refilling device 40. As illustrated in
As described above, the reservoir 50 comprises aerosol-generating material 52 for transferring, by the refilling device 40, to the article 30 in order to refill or replenish the aerosol-generating material 32 in the aerosol-generating material storage area 39 of the article 30.
The reservoir 50 illustrated in
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-generating material 52 when the reservoir 50 is filled with aerosol 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 the article 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-generating material 52, a volume of aerosol-generating material 52 at least 5 times greater than the aerosol-generating material storage area 39 of the article 30. This allows the same 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 the article interface 42 is configured to receive.
The refilling device 40 illustrated in
In the same fashion, the refilling device 40 illustrated in
Although the connectors 31, 41, 47, 51 are described herein as physical electrical connectors between the article, the refilling device and the reservoir, in an alternative implementation one or more of the electrical connections between the respective components may be a wireless connection, such as NFC, RFID, or inductive coupling.
The refilling device 40 illustrated in
Although the refilling outlet 44 is illustrated in
Further, as described above, the refilling device 40 may be configured to receive different types, designs or configuration of article 30 using the same article interface 42. In this case, there may be multiple configurations of connectors 41 and/or refilling outlets 44 proximate to or in the article interface 42 in order to facilitate the same article interface 42 receiving different types, designs or configurations of article 30. Equally, there may be multiple configurations of connectors 47 and/or refilling inlets 45 proximate to or in each reservoir interface 46 in order to facilitate the same reservoir interface 46 receiving different types, designs or configurations of reservoir 50. Alternatively or in addition, the configuration of connectors 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 by different reservoir interfaces 46 of the same refilling device 40.
One or more of the refilling outlet 44, the refilling inlets 45, the reservoir outlet 55 and the duct 43 may also include a means of controlling the rate and/or direction of transfer of the aerosol-generating material 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 refilling outlet 44, the refilling inlets 45 and the reservoir outlets 55 to ensure that aerosol-generating material 52 can only be transferred from the reservoir 50 to the refilling device 40 and from the refilling device 40 to the article 30, whilst a single ball valve or diaphragm may be located on or in the duct 43 of the refilling device 40 in order to control the flow rate of aerosol-generating material 52 from the reservoir 50 through the refilling device 40 and into the article 30. Equally, a ball valve or diaphragm may be located proximate to each refilling inlet 45 in order to independently control the rate of transfer of aerosol-generating material 52 into each of the refilling inlets 45 or from each of the refilling inlets 45 into the duct 43. For example, this allows the refilling control circuitry 48 to prevent a first aerosol-generating material 52 being transferred from a first reservoir 50 whilst a second aerosol-generating material 52 is being transferred from a second reservoir 50 to the article 30. This also allows the refilling control circuitry 48 to facilitate the transfer the first aerosol-generating material 52 from the first reservoir 50 and the second aerosol-generating material 52 from the second reservoir 50 simultaneously to the article 30, but at different transfer rates, thereby creating an aerosol-generating material 32 in the article 30 containing a mixture of the first aerosol-generating material 52 and the second aerosol-generating material 52 at different concentrations.
The refilling device 40 illustrated in
The device interface 49 can be configured to receive the aerosol provision device 20 in order to supply electrical power from the refilling device 40 to the aerosol provision device 20. This electrical power can be used, for example, to recharge the power source or battery 14 of the aerosol provision device 20 and to facilitate the transfer of electrical signals between the refilling control circuitry 48 and the device control circuitry 28. This allows the user to use the refilling device 40 as a means of charging the aerosol provision device 20 whilst the article 30 is being replenished with aerosol-generating material 32, thereby reducing the number of associated devices needed to operate and maintain the aerosol provision system 10. The device 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. The device interface 49 may also be configured to the transfer of data between the refilling control circuitry 48 and the device control circuitry 28. The refilling control circuitry 48 may be configured to read data from the aerosol provision device and/or write data to the aerosol provision device 20, for example to perform a software update, thereby installing an updated version of software onto the device control circuitry 28.
As set out above, the refilling device 40 facilitates the transfer of aerosol-generating material 52 from a reservoir 50 couplable to the refilling device 40 to an article 30 couplable to the refilling device 40 in order to refill or replenish the article 30 so that it can be reused as part of the aerosol provision system 10. In particular, the refilling control circuitry 48 is configured to facilitate the transfer of aerosol-generating material 52 from the reservoir 50 to the article 30 in response to detecting that the article 30 has been received by the refilling device 40.
By way of a concrete example, when a reservoir 50 is received by one of the reservoir interfaces 47, the connectors 47 located proximate to or in the corresponding reservoir interface 46 mate with the connectors 51 on the reservoir 50 and the refilling inlet 45 located proximate to or in the corresponding reservoir interface 46 mates with the reservoir outlet 55. When an article 30 is received by the article interface 42, the connectors 41 located proximate to or in the article interface 42 mate with the connectors 31 on the article 30 and the refilling outlet 45 mates with the refilling orifice 34 on the device 30. The refilling control circuitry 48 is then configured to facilitate the transfer of aerosol-generating material 52 from the reservoir 50 to the article 30 by facilitating the transfer of aerosol-generating material 52 from the reservoir 50 into the duct 42 of the refilling device 40 via the reservoir outlet 51 and the refilling inlet 45, and from the duct 42 of the refilling device 40 into the aerosol-generating material storage area 39 of the article 30 via the refilling outlet 44, the refilling orifice 34 and the refilling tube 33.
In the examples where the refiling device 40 has a plurality of reservoir interfaces 46, the refilling control circuitry 48 is configured to selectively facilitate the transfer of aerosol-generating material 52 from a reservoir 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 a reservoir 50, or in response to a selection of a particular reservoir 50 from which aerosol-generating material 52 should be transferred, for example a user input or a determination based on one or more parameters of each of the reservoirs 50 stored on the respective reservoir control circuitry 58. In this case, the refilling control circuitry 48 is configured to receive, from a user of the refilling device 40, a selection of one or more reservoir interfaces 46 and selectively facilitate the transfer of aerosol-generating material 52, from each reservoir 50 connected to one of the one or more selected reservoir interfaces 46, to the article 30 when the article 30 is coupled to the refilling device. In other words, the refilling control circuitry 48 is configured to only transfer aerosol-generating material 52 from a reservoir 50 connected to a selected reservoir interface 46, and prevent aerosol-generating material 52 from being transferred from any other reservoir 50 connected to the refilling device 40.
Although not illustrated, in some examples, the refilling device 40 can comprise a tank, container or other such receptacle for storing aerosol-generating material 52 received from the reservoir 50, for example when a reservoir 50 is received by the reservoir interface 46 without an article 30 being received by the article interface 42, thereby allowing the reservoir 50 to be disconnected from the reservoir interface 46 before an article 30 is received by the article interface 42. In this case, the aerosol-generating material 52 is stored in the receptacle of the refilling device 40 until such a time that it can be transferred to an article 30 received by the article interface 42. In this case, control circuitry 48 of the refilling device 40 is configured to facilitate the transfer of aerosol-generating material 52 from the reservoir 50 to the receptacle, and subsequently and separately to facilitate the transfer of the aerosol-generating material 52 from the receptacle to the article 42.
The receptacle of the refilling device 40 can also be used to facilitate the mixing of aerosol-generating material 52 before it is transferred to the article 30. For example, if a first reservoir interface 46 receives a first reservoir 50 containing a first aerosol-generating material 52 and a second reservoir interface 46 receives a second reservoir 50 containing a second aerosol-generating material 52, then the refilling control circuitry 48 can be configured to facilitate the transfer of the first aerosol-generating material 52 from the first reservoir 50 into the receptacle, and facilitate the transfer of the second aerosol-generating material 52 from the second reservoir into the receptacle. The first aerosol-generating material 52 and the second aerosol-generating material 52 can then be mixed in the receptacle, and the mixture of the first aerosol-generating material 52 and the second aerosol-generating material 52 transferred to the article

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 420a, 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 420a. Alternatively, the refilling control circuitry 48 may detect that the holder 420 is in the closed configuration 420a, 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 420a 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.
As described above, 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 420a. 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.
The holder 420 is configured to receive the article 30 when the holder 420 is in the open configuration 420b. In other words, since the holder 420 is at least partially located outside the housing 400 of the refilling device 40 in the open configuration 420b, 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 420b such that the article 30 is received by the holder 420 of the article interface 42. When the holder 420 slides between the open configuration 420b and the closed configuration 420a, 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 holder illustrated in
The tray 420 can comprise a trough with a size and shape substantially conforming to a perimeter size and shape of the article 30. In other words, 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 420b and the closed configuration 420a. 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 420a. In other words, 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 420a in order to facilitate the transfer of aerosol generating material into the article 30.
As can be seen by comparing the axes in
Although not illustrated, the holder 420 may comprise the one or more connectors 41, such as contact electrodes, connected via electrical wiring to the refilling control circuitry 48 to facilitate communication between the refilling control circuitry 48 and the article control circuitry 38; the connectors 31 on the article 30 mate with the connectors 41 on the holder 420 when the article 30 is received by the holder 420, thereby allowing power to be supplied from the refilling device 40 to the article control circuitry 38 and electrical signals to be transferred between the refilling control circuitry 48 and the article control circuitry 38. The connectors 41 may be arranged relative to the holder 420, for example in the tray and/or trough, in a pattern and position matching/mirroring the connectors 31 on the article 30 in order to facilitate the mating of the connectors 31 on the article 30 and the connectors 41 on the holder 420 when the article 30 is received by the holder 420.
Although not illustrated, a motor may be connected to the holder 420, with the refilling control circuitry 48 configured to operate the motor to slide the holder 420 between the open configuration 420b and the closed configuration 420a. Alternatively, the holder 420 may comprise a biasing means, such as a spring, configured to bias the holder 420 towards the open location 420b. A force then needs to be applied on the holder 420 to overcome the biasing means and slide the holder 420 to the closed configuration 420a. In this case, there may be a latch, clip or other retaining mechanism to hold the holder 420 in the closed configuration 420a.
The refilling control circuitry 48 can be configured to operate the motor to slide the holder 420 into the closed configuration 420a in response to the article 30 being received by the holder 420. For example, the refilling control circuitry 48 may be configured to detect, for example using a sensor or contact electrode such as a connection between the connectors 31, 41, when the article 30 has been received by the holder 420, and to operate the motor to slide the holder 420 into the closed configuration 420a in response to detecting that the article 30 has been received by the holder 420. Alternatively, the refilling control circuitry 48 may detect that the article 30 has been received by the holder 420, but operate the motor 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. The refilling control 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 the holder 420 to the open configuration 420b in response to 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 that the transfer of aerosol-generating material 52 from the reservoir 50 to the article 30 is complete and to operate the motor in response to detecting that the transfer of aerosol-generating material 52 is complete. Alternative, as described above, the refilling control circuitry 48 may detect that the transfer of aerosol-generating material 52 from the reservoir 50 to the article 30 is complete, but operate the motor 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. The refilling control 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 the article 30 into the holder 420, the user can push the holder 420, for example on the outer surface 421, to overcome the biasing means and slide the holder 420 from the open configuration 420b to the closed configuration 420a, where the retaining mechanism retains the holder 420 in the closed configuration 420a. In response to detecting that the transfer of aerosol-generating material 52 from the reservoir 50 to the article 30 is complete, the refilling control circuitry 48 can be configured to release the retaining mechanism such that the biasing means slides the holder 420 from the closed configuration 420a to the open configuration 420b. Alternatively, the refilling control circuitry 48 may detect that the transfer of aerosol-generating material 52 from the reservoir 50 to the article 30 is complete, but release the retaining mechanism 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. The refilling control 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 refilling control circuitry 48 can be configured to release the retaining mechanism, such that the biasing means slides the holder 420 from the closed configuration 420a to the open configuration 420b. 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 the refilling device 40 based on the transfer of aerosol-generating material 52 from the reservoir 50 to the article 30. For example, the refilling control 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 the article 30 has been received by the holder 420, the reservoir 50 has been received by the reservoir interface 46 and/or that the transfer of aerosol-generating material 52 from the reservoir 50 to the article 30 is beginning, in progress, and/or complete.

The reservoir 50 illustrated in
The reservoir 50 illustrated in
The reservoir 50 also comprises (not illustrated) reservoir control circuitry 58 configured to control the reservoir 50 and store parameters and/or data associated with the reservoir 50. The parameters associated with the reservoir 50 may include, for example data indicative of an amount of aerosol-generating material 52 stored in the reservoir 50, data relating to the aerosol-generating material 52 stored in the reservoir 50, 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 52. The data may also comprise an identifier, such as a serial number and/or SKU for the reservoir 50 or other means of identifying the reservoir 50 and/or the type of the reservoir 50, and a date of manufacture and/or expiry of the reservoir 50. As described above in relation to the device control circuitry 28, the reservoir 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, the reservoir control circuitry 58 may comprise a microcontroller unit (MCU) or a system on chip (SoC). Alternatively, the reservoir 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 in
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-generating material 52 when the reservoir 50 is filled with aerosol generating material 52. The reservoir interface 46 of the refilling device 40 is then configured to receive a reservoir 50 with a volume of 10 ml or more.
The reservoir 50 can also have a larger volume than the article 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-generating material 52, a volume of aerosol-generating material 52 at least 5 times greater than the aerosol-generating material storage area 39 of the article 30. This allows the same reservoir 50 to be used to refill the article at least 5 times. The reservoir interface 46 of the refilling device 40 is then configured to receive a reservoir 50 with a volume at least 5 times greater than a volume of the article the article interface 42 of the refilling device 40 is configured to receive.
Although not illustrated, the reservoir 50 may also comprise a window on a sidewall of the reservoir 50 to allow the user to see the amount of aerosol-generating material 52 contained in the reservoir 50. Alternatively, a portion of a sidewall of the reservoir 50 may be transparent to allow the user to see through the sidewall to see the amount of aerosol-generating material 52 contained in the reservoir 50.

As described above with reference to
The reservoir interface 46 illustrated in
The holder 460 illustrated in
The holder 460 is also configured such that the reservoir outlet 55 on the reservoir 50 is located proximate to the refilling inlet 45 when the reservoir 50 is received by the holder 460. This allows the refilling inlet 45 to mate with a reservoir outlet 55 during the transfer of aerosol-generating material 52 from the reservoir 50 to the article 30. In other words, the holder 460 is a size and shape such when the reservoir 50 is located in the holder 460 and retained by the retaining mechanism 461, the reservoir outlet 55 on the reservoir 50 is located proximate to the refilling inlet 45.
The holder 460 may be a size and shape such that the reservoir 50 can only be received by the holder 460 in one orientation, such that reservoir outlet 55 on the reservoir 50 is located proximate to the refilling inlet 45 and the connectors 51 on the reservoir 50 mate with the connectors 47 on the holder 460 when the reservoir 50 is received by the holder 460 (i.e. the reservoir 50 is located in the holder 460 and retained by the retaining mechanism 461).
The holder 460 is configured to receive the reservoir 50 in a horizontal direction (along the x-axis in
The reservoir interface 46 illustrated in
The housing 400 illustrated in
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 the closed configuration 463a, and to facilitate the transfer of aerosol-generating material 52 from the reservoir 50 to the article 30 in response to detecting that the access panel 463 is in the closed configuration 463a. Alternatively, the refilling control circuitry 48 may detect that the access panel 463 is in the closed configuration 463a, but only facilitate the transfer of aerosol-generating material 52 from the reservoir 50 to the article 30 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 access panel 463 is in the closed configuration 463a ensures that the reservoir interface 46 encloses the reservoir 50 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 reservoir 50 during the transfer of aerosol-generating material 52, thereby improving the safety of the transfer and refilling process.
As illustrated in
The access panel 463 illustrated in
The access panel 463 illustrated in
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 the closed configuration 463b. This allows the user to see through the access panel 463 and the reservoir 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 the reservoir opening 462 when the access panel 463 is in the closed configuration 463b may be transparent to allow the user to see through the access panel 463 and the reservoir opening 462 to observe the reservoir and the refilling process.
As described above, the reservoir interface 46 is configured to receive the reservoir 50 when the access panel 463 is in the open configuration 463b. The reservoir 50 is received by the holder 460 and the retaining mechanism 461 retains the reservoir 50 in the holder 460. In order to remove the reservoir 50 from the reservoir interface 46, the user may be able to pull on a surface of the reservoir 50, such as the hold 540, in order to provide a force to overcome the retaining mechanism 461. For example, where the retaining mechanism 461 is a spring clip, pulling on the hold 540 of the reservoir 50 will provide sufficient force to overcome the retaining force of the spring clip and to remove the reservoir 50 from the reservoir interface 46. Alternatively, the refilling control circuitry 48 is configured to release the retaining mechanism, for example in response to the transfer of aerosol-generating material 52 from the reservoir 50 to the article 30, or in response to a user input on an input means. Where the retaining mechanism 461 is a latch, the reservoir 50 may only be removable from the reservoir interface 46 in response to the latch being released, either by the refilling control 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 the reservoir 50 such that the hold 540 is located proximate and/or is the closest point on the reservoir to the reservoir opening 462, thereby allowing the user to grip and pull on the hold 540 in order to remove the reservoir 50 from the holder 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 the open configuration 463b and the closed configuration 463a. Alternatively, the access panel 463 may comprise a biasing means, such as a spring, configured to bias the access panel 463 towards the open configuration 463b. A force then needs to be applied on the access panel 463 to overcome the biasing means and move the access panel 463 to the closed configuration 463a. In this case, there may be a latch, clip or other retaining means to hold the access panel 463 in the closed configuration 463a.
The access panel 463 may be configured to move between the open configuration 463b and the closed configuration 463a in response to an input on the refilling device 40 by a user of the refilling device 40. For example, where the access panel 463 comprises a motor, the refilling device 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 refilling control circuitry 48 can be configured to operate the motor to move the access panel 463 from the open configuration 463b to the closed configuration 463a. The refilling control circuitry 48 can be configured to operate the motor to move the access panel 463 from the closed configuration 463a to the open configuration 463b 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 the closed configuration 463a to the open configuration 463b. 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 the outer surface 464, to overcome the biasing means and return the access panel 463 from the open configuration 463b to the closed configuration 463a, where the retaining means retains the access panel 463 in the closed configuration 463a.
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 the refilling 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 the closed configuration 463a.

The device interface 49 is configured to slide between the first location 49a and the second location 49b. For example, the device interface 49 and a portion of the refilling device may comprise rails and corresponding grooves to allow the device interface 49 to side in a planar fashion (e.g. along the z-axis as illustrated in
A motor may be connected to the device interface 49, with the refilling control circuitry 48 configured to operate the motor to move the device interface 49 between the first location 49a and the second location 49b. Alternatively, the device interface 49 may comprise a biasing means, such as a spring, configured to bias the device interface 49 towards the second location 49b. A force then needs to be applied on the device interface 49 to overcome the biasing means and move the device interface 49 to the first location 49a. In this case, there may be a latch, clip or other retaining mechanism to hold the device interface 49 in the first location 49a.
The device interface 49 may be configured to slide from the first location 49a to the second location 49b in response to an input on the refilling device 40 by a user of the refilling device 40. For example, where the device interface 49 comprises a motor, the refilling device 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 refilling control circuitry 48 can be configured to operate the motor to move the device interface 49 from the first location 49a to the second location 49b. The refilling control circuitry 48 can be configured to operate the motor to move the device interface 49 from the second location 49a to the first location 49b 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 refilling control circuitry 48 can be configured to release the retaining mechanism, thereby allowing the biasing means to more the device interface 49 from the first location 49a to the second location 49b. 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 the device interface 49, for example on the outer surface 491, to overcome the biasing means and return the device interface 49 from the second location to the first location, where the retaining mechanism retains the device interface 49 in the first location 49a.
In each case, the input means may be located on the housing 400 of the refilling device proximate to the device interface 49, or on a different location on the refilling device 40. Alternatively, the input means may be located on the device interface, such as on the outer surface 491 of the device interface 49.

By comparing
As described above, the refilling control circuitry 48 of the refilling device is configured to facilitate the transfer of aerosol-generating material 52 from a reservoir 50 to an article 30. For example, the refilling control circuitry 48 can facilitate the transfer of aerosol-generating material 52 from a reservoir 50 to an article 30 in response to detecting that the article 30 has been received by the refilling device 40. As described above, the refilling control circuitry 48 can be configured to detect that the article 30 has been received by the article interface 42, such as by detecting the connectors 31 on the article 30 mating with the connectors 41 on the refilling device when the article 30 is received by the article interface 42. As described above, the refilling control circuitry 48 may additionally detect that an article 30 has been received by a holder 420 of the article interface 42, and that the holder is in a closed configuration before facilitating the transfer of aerosol-generating material 52 from a reservoir 50 to an article 30.
The refilling control circuitry 48 is further configured to determine an amount of aerosol generating material in the article 30 in response to detecting that the article 30 has been received by the refilling device 40. As described above, the refilling control circuitry 48 can be configured to communicate with article control circuitry 38 in the article 30. The refilling control circuitry 48 can therefore determine an amount of aerosol generating material in the article 30 by communicating with the article control circuitry 38 and receiving an indication of the amount of aerosol generating material in the article 30 from the article control circuitry 38. Alternatively, the refilling device 40 may comprise a sensor, such as a light, capacitive or ultrasonic sensor configured to detect the amount of aerosol generating material in the article 30. The refilling control circuitry 48 can control the sensor to detect the amount of aerosol generating material in the article 30 in response to detecting that the article 30 has been received by the refilling device 40, and then determine the amount of aerosol generating material in the article 30 based on data received from the sensor.
The refilling control circuitry 48 is then configured to facilitate the transfer of aerosol generating material 52 from the reservoir 50 to the article 30 in response to determining that the amount of aerosol generating material in the article 30 is less that an article threshold. As will be appreciated, the article 30 need only be refilled with aerosol generating material when there is little or no aerosol generating material remaining in the article 30. The article threshold is therefore set to ensure that the transfer of aerosol generating material 52 from the reservoir 50 to the article is not attempted when there is already a sufficient amount of aerosol generating material in the article 30. For example, the article threshold may correspond to half of the capacity or volume of the aerosol-generating material storage area 39 of the article 30, or correspond to less than half capacity of the aerosol-generating material 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 of aerosol generating material 52, and the refilling control circuitry 48 may be configured to provide a notification to the user.
The amount of aerosol generating material 52 transferred from the reservoir 50 to the article 30 can be based on the amount of aerosol generating material in the article 30. For example, the refilling control circuitry 48 can be configured to determine the amount of capacity or volume of the aerosol-generating material storage area 39 of the article, for example by communicating with the article control circuitry 38. The refilling control circuitry 48 is then configured to facilitate the transfer of an amount of aerosol generating material 52 from the reservoir 50 to the article 30 such that the aerosol-generating material storage area 39 of the article 30 is full or at capacity with aerosol generating material. In other words, the amount of aerosol generating material 52 transferred from the reservoir 50 to the article 30 corresponds to the difference between the capacity or volume of the aerosol-generating material storage area 39 of the article 30 and the amount of aerosol generating material in the article 30.
The refilling control circuitry 48 can also be configured to facilitate the transfer of aerosol-generating material 52 from the reservoir 50 to the article 30 in response to detecting that the reservoir 50 has been received by the refilling device 40. As described above, the refilling control circuitry 48 can be configured to detect that the reservoir 50 has been received by the reservoir interface 46, such as by detecting the connectors 51 on the reservoir 51 mating with the connectors 47 on the refilling device 40 when the reservoir 50 is received by the reservoir interface 46. As described above, the refilling control circuitry 48 may additionally detect that a reservoir 50 has been received by a holder 460 of the reservoir interface 46, and that an access panel 463 is in a closed configuration before facilitating the transfer of aerosol-generating material 52 from a reservoir 50 to an article 30.
The refilling control circuitry 48 is further configured to determine an amount of aerosol generating material 52 in the reservoir 50 in response to detecting that the reservoir 50 has been received by the refilling device 40. As described above, the refilling control circuitry 48 can be configured to communicate with reservoir control circuitry 58 in the reservoir 50. The refilling control circuitry 48 can therefore determine an amount of aerosol generating material in the reservoir 50 by communicating with the reservoir control circuitry 58 and receiving an indication of the amount of aerosol generating material in the reservoir 50 from the reservoir control circuitry 58. Alternatively, the refilling device 40 may comprise a sensor, such as a light, capacitive or ultrasonic sensor configured to detect the amount of aerosol generating material 52 in the reservoir 50. The refilling control circuitry 48 can control the sensor to detect the amount of aerosol generating material in the reservoir 50 in response to detecting that the reservoir 50 has been received by the refilling device 40, and then determine the amount of aerosol generating material in the reservoir 50 based on data received from the sensor.
The refilling control circuitry 48 can then be configured to facilitate the transfer of aerosol generating material 52 from the reservoir 50 to the article 30 in response to determining that the amount of aerosol generating material 52 in the reservoir 50 is greater than a reservoir threshold. The reservoir threshold represents a minimum amount of aerosol generating material 52 that can be transferred from the reservoir 50 to the article 30. If the amount of aerosol generating material 52 in the reservoir 50 is less than a reservoir threshold, then it is not possible to facilitate the transfer of aerosol generating material 52, and the refilling control circuitry 48 may be configured to provide a notification to the user.
The amount of aerosol generating material 52 transferred from the reservoir 50 to the article 30 can be based on the amount of aerosol generating material 52 in the reservoir 50. For example, if the amount of aerosol generating material 52 in the reservoir 50 is less than an available capacity of the aerosol-generating material storage area 39 of the article 30 (in other words, if the amount of aerosol generating material 52 in the reservoir 50 is less than the difference between the capacity of the aerosol-generating material storage area 39 and the amount of aerosol generating material in the article 30) the refilling control circuitry 48 can be configured to facilitate the transfer of all of the aerosol generating material 52 from the reservoir 50 to the article 30. Alternatively, if the amount of aerosol generating material 52 in the reservoir 50 is less than an available capacity of the aerosol-generating material storage area 39 of the article 30 (in other words, if the amount of aerosol generating material 52 in the reservoir 50 is less than the difference between the capacity of the aerosol-generating material storage area 39 and the amount of aerosol generating material in the article 30), then the refilling control circuitry 48 can be configured to facilitate the transfer of an amount of aerosol generating material 52 from the reservoir 50 to the article 30 corresponding to the available capacity of the aerosol-generating material storage area 39 of the article 30. In other words, the refilling control circuitry 48 is configured to facilitate the transfer of aerosol generating material 52 from the reservoir 50 to the article 30 such that the aerosol-generating material storage area 39 of the article 30 is full of aerosol generating material.
As described above, the refilling control circuitry 48 can also be configured to transfer electrical power to the aerosol provision device 20 for charging a power source 14 of the aerosol provision device 20 in response to detecting that the aerosol provision device 20 has been received by the refilling device 40.
