Description

[0001] AEROSOL PROVISION DEVICE

[0002] Technical Field

[0003] The present disclosure relates to an aerosol provision device.

[0004] Background

[0005] Aerosol provision devices and systems are known. Common systems are activated by a user to create an aerosol by an aerosol provision device from an aerosol generating material which is then inhaled by the user. The device may provide an aerosol from the aerosol generating material in the device. Some devices have more than one aerosol generating material within the device to offer users a range of aerosols for inhalation. It can be desirable for the user to control the ability of the device to provide aerosol. This may be to allow a user control over the selection of aerosol provided by the device, in turn this may increase the user experience of the device. The different aerosol generating materials in the device may be depleted at different rates. The user may expect that if one aerosol generating material is available that all aerosol generating material within the device are available for use.

[0006] Methods and devices for increasing user control and improving user experience are disclosed herein.

[0038] Detailed

[0039] 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 apparatus and methods discussed herein which are not described in detail may be implemented in accordance with any conventional techniques for implementing such aspects and features.

[0040] 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 / device and electronic aerosol provision system / device. Furthermore, and as is common in the technical field, the terms "aerosol" and "vapour", and related terms such as "vaporise", "volatilise" and "aerosolise", may generally be used interchangeably.

[0041] Figure 1 illustrates a schematic view of an example of a modern aerosol provision device 10. The aerosol provision device 10 has a first aerosol generating region 12 arranged to generate a first aerosol. The aerosol provision device 10 has a second aerosol generating region 14 arranged to generate a second aerosol. Devices with multiple reservoirs or chambers for holding aerosol generating material are known. The aerosol provision device 10 has a mouthpiece 16 with an outlet to provide aerosol from the aerosol provision device 10 to a user. The user is able to select the first 12 or the second 14 aerosol generating region to provide an aerosol. There are different ways of doing this employed in modern devices. Figure 2 illustrates a schematic view of an example of an aerosol provision device 100 according to the present disclosure. The aerosol provision device 100 has at least one inlet 102 through which air can enter the device 100. The aerosol provision device 100 has at least one outlet 104 through which aerosol within the device 100 can pass. The device 100 has a first aerosol generating material containing region 110 arranged to contain a first aerosol generating material 112. The device 100 has a second aerosol generating material containing region 120 arranged to contain a second aerosol generating material 122. The device 100 has a moveable component 130 arranged to move between a number of predetermined positions comprising at least a first and a second position. The moveable component 130 comprises a portion 132 that is transparent or translucent. At least this portion 132 of the moveable component 130 is nonopaque. In the first position, the transparent and / or translucent portion 132 is arranged over a portion of the second aerosol generating material containing region 120. In the second position, the transparent and / or translucent portion 132 is arranged over a portion of the first aerosol generating material containing region 110.

[0042] In the example of Figure 2, the moveable component 130 is arranged such that the non-opaque portion 132 is arranged over a portion of the first aerosol generating material containing region 110. Figure 2 shows that the first aerosol generating material containing region 110 contains aerosol generating material 112. The level of the aerosol generating material 112 in aerosol generating material containing region 110 can be seen by a user through the transparent and / or translucent portion 132. In this way, by moving the moveable component so that the transparent and / or translucent portion 132 moves along the direction indicated by double-ended arrow A, the user is able to view into the first or second aerosol generating material containing regions 110, 120 and observe the level of aerosol generating material 112, 122 within the regions 110, 120. In this way, if the user wishes to use the device 100 they can check the liquid levels before activating the device 100 to prevent activation of the device 100 when there is no aerosol generating material to provide the selected aerosol. The device 100 has a mouthpiece 140 containing the outlet 104 on which the user may inhale.

[0043] In the example of Figure 2, the transparent and / or translucent portion 132 is a small portion of the moveable component 130. This need not be the case. The moveable component 130 may be formed of, in the majority, translucent or transparent material and arranged to increase ease of viewing into the aerosol generating material containing regions 110, 120 to see the aerosol generating material 112, 122 contained therein.

[0044] The moveable component 130 may be moved in a number of ways to allow temporary viewing into the aerosol generating material containing regions. The component 130 may be moved via rotation and / or translation or the like. The device 100 may be arranged to allow the user to move the moveable component 130 around a longitudinal axis of the device 100, via rotation, allowing the portion 132 to move along the direction indicated by arrow A.

[0045] The transparent or translucent portion 132 acts as a window in the moveable component 130 to allow user to see how much aerosol generating material remains in the tank or container of the aerosol generating material containing region. The portion 132 may rotate with the rotatable moveable component so that window 132 aligns with a section of the tank (aerosol generating material containing region) to allow the user to see liquid left in that tank. The aerosol generating material containing regions 110, 120 may be located towards an outer of the device 100 to increase ease of visibility. Centrally located aerosol generating material containing regions 110, 120 would increase the difficulty of clearing viewing the aerosol generating material 112, 122 contained therein during use.

[0046] The device 100 has a first flow channel arranged to provide fluid communication between at least one inlet 102, at least one outlet 104 and the first aerosol generating material containing region 110. The device 100 has a second flow channel arranged to provide fluid communication between at least one inlet 102, at least one outlet 104 and the second aerosol generating material containing region 120. In the first position, the moveable component 130 at least partially blocks the first flow channel and, in the second position, the moveable component 130 at least partially blocks the second flow channel.

[0047] In some in-use examples, therefore, the user moves the moveable component 130 to the first position. The transparent and / or translucent portion 132 (which may be referred to herein as a viewing window or the like) is moved to be over a portion of the second aerosol generating material containing region 120. The user is therefore able to view the remaining aerosol generating material 122 in the aerosol generating material containing region 120. By virtue of the same movement, the moveable component blocks the first flow channel, the first flow channel being from the inlet 102, past the first aerosol generating material containing region 110 to the outlet 104.

[0048] In this way, the user has, with one movement, selected the second aerosol generating material containing region 120 for use with the device 100 to provide an aerosol from the second aerosol generating material 122 and is able to check on the quantity of aerosol generating material 122 within the aerosol generating material containing region 120 prior to activation of the device 100. Therefore, the user is informed immediately prior to use whether the device 100 will be able to provide the aerosol requested by the user.

[0049] In the above examples, the viewing window 132 is used by the user to see directly the aerosol generating material within the selected aerosol generating material containing region. This may not be the only option. In some examples, the aerosol generating material containing region also comprises electronics to provide an aerosol, i.e. the aerosol generating material containing region is not just a tank, reservoir or chamber for storing aerosol generating material but also contains electronics for providing an aerosol. The viewing window 132 may be arranged to allow the user to view an atomizer, heater and / or microphone alongside or alternatively to the aerosol generating material within the aerosol generating material containing region. Each of these may provide information to the user on the suitability of providing an aerosol from the selected aerosol generating material.

[0050] In examples, therefore, the aerosol generating material containing regions may also be aerosol generating regions, and include elements such as atomizers, heaters, vibration plates, microphones, flow sensors, pressure detectors, and / or wicks or the like. Each of these may provide information to the user as to the condition of that aerosol generating region and its suitability for providing the requested aerosol. The device 100 may have one heating element per aerosol generating region, or may have more or fewer. The device 100 may have one heating element in total. The device 100 may have control circuitry and a puff detector, microphone or the like for activating the heating element or elements in the aerosol provision device 100. The device 100 may have one puff detector (or the like) per aerosol generating region, or may have more or fewer or have one puff detector in total. In Figure 2, the side wall of the aerosol generating material containing region 110 over which the viewing window 132 extends is shown in dashed lines. For total clarity, the aerosol generating material containing regions discussed herein may hold aerosol generating material of any form or type or flavour etc. The aerosol generating material may be solid or liquid etc. In this way the aerosol generating material containing regions may be reservoirs or chambers or tanks or the like. Solid aerosol generating material may be contained on a spike or the like within a region. The region may not be a completely confined portion of space, as a block of aerosol generating material on a spike would not require totally surrounding with a structure. The aerosol generating material may comprise flavours and / or stimulants or the like. Where there are at least two aerosol generating material containing regions, they may contain different aerosol generating materials. This may be different flavours entirely or may be strengths of the same aerosol generating material. The user is allowed to switch between the two aerosol generating materials as desired and therefore it is reasonable to assume the user switches due to the differences in the aerosol generating materials in the device.

[0051] The two or more aerosol generating material containing regions may share a chamber superstructure with some form of divide between them to prevent cross contamination. This may be advantageous for space saving purposes within the device. Within the superstructure there may be one or more heaters. The aerosol generating materials may have a common heater or separate individual heaters as will be discussed in more detail later.

[0052] In a specific example, at least a portion of the first aerosol generating material chamber is transparent and / or translucent and at least a portion of the second aerosol generating material chamber is transparent and / or translucent. The whole chamber may be transparent or the chamber could be formed from a cage-like structure that would allow the user to view through the cage. In particular, where the aerosol generating material contained within the chamber is a solid, a cage-like structure may be advantageous for improving visibility of the aerosol generating material (and other components within the chamber) by the user. Where the aerosol generating material is a liquid, a transparent reservoir may be advantageous for improving visibility. Alternatively, a reservoir may have a transparent portion along one side of the reservoir to show the level of the liquid within the reservoir. The containing regions may be 3D printed and therefore materials may be chosen to improve visibility into the regions. In some examples, in the first position the transparent and / or translucent portion of the moveable component at least partially aligns with the transparent and / or translucent portion of the second aerosol generating material chamber. In this way, the user sees into the second aerosol generating material chamber of the device, having selected the second aerosol for aerosolisation by the device. Again, prior to use, the user is informed as to the suitability of that aerosol for use. Correspondingly, in the second position the transparent and / or translucent portion of the moveable component at least partially aligns with the transparent and / or translucent portion of the first aerosol generating material chamber.

[0053] Referring now to Figure 3, there is shown an example of a device 200. The device 200 has a series of features in common with the device 100 of Figure 2. Similar features, i.e. features that perform the same function, are shown with numerals increased by 100. Such as inlet 202 of device 200 allows air into the device 200 as per inlet 102 of device 100. Such features may not be described in detail for brevity.

[0054] The transparent / translucent portion 232 of the moveable component 230 is of a different shape in Figure 3 when compared to Figure 2. The viewing window 232 is able to be moved over the full length of the aerosol generating material containing regions 210, 220. By rotating the moveable component 230 in the direction of arrow B, the window 232 may be moved over the aerosol generating material containing regions 210, 220 to view the level of aerosol generating material therein. In particular, the additional size of the window 232 (compared to the example of Figure 2) allows the user to check the level of aerosol generating material in the regions 210, 220 in any orientation. If the user stands the device on end 206, the aerosol generating material (if in liquid form) may move to the end 214 of aerosol generating material containing region 210. The extended window 232 (compared to Figure 2) allows the user to view a liquid that has moved to the end 214 of the aerosol generating material containing region 210. In this way, the user will always have visibility of the aerosol generating material level in the aerosol generating material containing region 210 prior to activating the device 200. As mentioned above, this increases the ease of recognition of problems prior to activation of the device 200 such as low or no aerosol generating material in the aerosol generating material containing region 210. In some examples, a simple movement such as a rotation in direction of arrow B as this is likely accessible to most users. While a complex motion may increase the prevention of accidental movement e.g. when the device 200 is being transported in a bag or pocket or the like, this may be hard for users with reduced mobility to recreate. As such, a balance should be made between these two competing desires.

[0055] In use, the user holds the moveable component 230 and moves the moveable component 230 so that the moveable component 230 reveals a portion of one of the aerosol generating material containing regions and also blocks a specific flow path in the device 200. The user may contact the device 200 away from the mouthpiece 240 to do so (as the moveable component 230 is separate from the mouthpiece 240) and move the moveable component 230. The movement action to move the moveable component may be done with two hands, or one hand to increase accessibility for certain users.

[0056] The mouthpiece 240 is shown in the example of Figure 3 with one outlet 204. In the example of Figure 3, therefore, at least at the inlet 202 and the outlet 204 the first flow channel and second flow channel share some portion of their flow channels. In other examples, e.g. with multiple inlets and outlets, the first flow path and second flow path may be entirely separate. The mouthpiece 240 is designed to fit comfortably in the mouth of a user. The user inhales on the mouthpiece 240 and aerosol is provided to the user from within the device 200. The aerosol provided to the user depends on the position of the moveable component 230. As mentioned, in the first position the first flow channel may be blocked thereby providing aerosol from the second aerosol generating region 220. In the second position, the second flow channel is blocked thereby providing aerosol from the first aerosol generating region 210. In this way, the user is provided with a choice of aerosols from a single device 200.

[0057] The terms flow paths and flow channels may be used herein interchangeably.

[0058] The moveable component 230 is shown in Figure 3 between the mouthpiece 240 and the aerosol generating material containing regions 210, 220. In the example shown the moveable component 230 abuts moveable component 240 and the aerosol generating material containing regions 210, 220. In another example, the moveable component 230 may be “between” the mouthpiece portion 240 and the first 210 and the second 220 aerosol generating material containing regions in the sense of being upstream of the mouthpiece 240 and downstream of the first 210 and the second 220 aerosol generating material containing regions. “Upstream” and “downstream” here are used to refer to the flow path(s) or flow channel(s). “Upstream” is therefore earlier in the flow path and “downstream” is later in the flow path, such that airflow flows past an upstream element before a downstream element. The flow path (or flow channel) will typically start at an inlet and end at an outlet. The elements relevant to the flow path can therefore be relatively closer to the inlet (upstream) or relatively closer to the outlet (downstream).

[0059] A portion of the moveable component 230 may be located between the mouthpiece portion 240 and the first 210 and the second 220 aerosol generating material containing regions. The location of a portion of the moveable component 230 upstream of the mouthpiece 240 improves the ease of use of the moveable component 230 as the user can operate the flavour switching of the device 200 without needing to hold the mouthpiece 240 portion which may be unhygienic. At least a portion of the moveable component is therefore located in an easily accessible area of the device 200. The position of the moveable component 230 may be located where a user’ s thumb typically is placed on an elongate housing, such as may be used (and, indeed, is typical) for the device 200. A user’s thumb easily moves the moveable component 230 such that a change in flavour is provided from the device 200. The user therefore does not need to adjust their grip or touch the mouthpiece. Both of these increase the user experience via synergistically improving ease of use and increasing enjoyment of use.

[0060] In some examples, the device 200 is elongate. In some examples, the device has a circular cross section. In some examples, the device 200 is cylindrical. In this example, the moveable component 230 may be in the form of collar as a separated portion of the outer housing. The moveable component 230 may be movable separate from the rest of the outer housing.

[0061] In this way, a mechanical solution is provided for flavour switching in a device 200. The user is able to move the moveable component 230 between at least two positions. The moveable component 230 is therefore a reliable and robust method of flavour switching in a single aerosol provision device 200 enabling switching with reduced user effort, compared to e.g. swapping out an aerosol generating material container from within the device 200. As such, the present device provides advantages in both cleanliness and user experience. In the example of Figure 4, there is shown an arrangement 300 of a device portion including a moveable component arrangement for preventing the moveable component moving beyond predetermined positions within a device. In the example of Figure 4, the arrangement 300 has an aerosol provision device housing 310. Within the housing 310 is an array of predetermined positions 320. The array of predetermined positions 320 has a first predetermined position 322, a second predetermined position 324, a third predetermined position 326, and a fourth predetermined position 328. The moveable component may have a projection that enters a recess located at each of the predetermined positions 320. The moveable component may have a resilient member arranged to extend into a recess at a predetermined position 320 when suitably aligned, or arranged to bias a projection (or electrical contact) into a recess when suitably aligned. The projection may comprise a resilient member to bias the projection into the recess when the moveable component reaches a predetermined position during movement.

[0062] The projection may be a spring and ball bearing or the like. Alternatively, a resilient plastic piece with a bump in it (or the like) for providing pressure towards the recess. The moveable component may comprise the projection or the recess or an arrangement chosen to mirror the arrangements of the device so that the predetermined positions are moved to and securely selectable by a user.

[0063] In some examples, in the first predetermined position 322, the viewing window is located over a portion of the second aerosol generating material containing region. In some examples, in the second predetermined position 324, the viewing window is located over a portion of the first aerosol generating material containing region.

[0064] Additionally, in the first predetermined position 322, the flow path including the first aerosol generating material containing region is partially blocked, thereby supplying the user with aerosol from the second aerosol generating material containing region.

[0065] Additionally, in the second predetermined position 234, the flow path including the second aerosol generating material containing region is partially blocked, thereby supplying the user with aerosol from the first aerosol generating material containing region. In these examples, the user is able to safely, reliably and easily move the moveable component into a predetermined position 320. The arrangement 300 has a pair of stoppers 330. The stoppers 332, 334 prevent the moveable component moving beyond the predetermined positions 320. The stoppers 332, 334 may physically (or otherwise) prevent movement of a projection or a resilient member and therefore provide feedback to the user that further movement in the same direction is not permitted. The stoppers 330 may be arranged adjacent, or reasonably proximal to, the outermost predetermined positions 322, 328 (in the example of Figure 4). Use of a stopper, or stoppers, improves the overall safety of the aerosol provision device disclosed herein.

[0066] The stoppers 330 may be arranged to limit movement to a specific number of degrees of rotation (for example) or a certain distance of translation or insertion. In some examples, the stoppers 330 may prevent movement beyond a certain amount of degrees of the moveable component. The stoppers 330 and the predetermined positions may demonstrate latching behaviour when interacting with the moveable component to help inform the user of the allowed range of movements of the moveable component. This increases the safety and reliability of the device, by reducing the likelihood of a user moving the moveable component too far and potentially damaging the device. Preventing over-rotation has also been shown to reduce the likelihood of leakage from the device. As such, stoppers are advantageous for this reason.

[0067] In some examples, the moveable component has a first position 180 degrees away from the second position. In this way, the selection between the first or second aerosol is clear for a user. The greater separation between the two positions, the decreased likelihood of a user accidentally selecting a non-desired aerosol for inhalation. Decreasing this likelihood increases the user experience of the device.

[0068] In some examples, the moveable component is further arranged to move to a third position, wherein the third position is a predetermined position (which may be deemed a latched position due to the interaction of projection and recesses) wherein the aerosol provision device is in an inoperable mode, i.e. a locked state. In this example, the moveable component may be moved to a third position (such as 326 from Figure 4). In the third position, the moveable component is latched, i.e. the moveable component is secured and at least slightly prevented from moving away from this position. Such latching may occur by aligning of a resilient member or projection and a recess or the like. In this example, the resilient member / proj ection projects into the recess and some additional mechanical effort is required to move the moveable component out of the recess and into a further predetermined position, such as position 328. This may provide the device with an “off’ position into which the device can be put after conclusion of a smoking session. In such a predetermined position, the viewing window may not be located over an aerosol generating material containing region. In this way, the user understands that the device is in a non operable state such as “locked” or “off’.

[0069] When the moveable component is moved to the third position, the device may be inoperable, for example this may be in a sleep mode or a locked mode or an “off’ mode or the like. In this position, the moveable component may block at least one flow channel. In this position, the moveable component may block some portion of all flow channels in the device, to prevent an aerosol being provided to a user. While in one of these modes (lock, sleep, etc), the user cannot receive an aerosol from the device without changing the mode. The user may change the mode by moving the moveable component into a different predetermined position. Any predetermined position may be a latched position, i.e. a position from which additional effort is required from the user to move out of the predetermined position.

[0070] In the example of Figure 4, there are positions between the predetermined positions indicated 320, such as position 340. In the present disclosure, the position 340 is not considered a predetermined position 320 as the moveable component will not latch into place in position 340. The positions that are not “predetermined positions” are not intended for the user to move the moveable component to and then leave the moveable component in. As such, moving the moveable component from a non-predetermined effort requires no additional effort from the user.

[0071] In some examples, the aerosol provision device is configured to be in an inoperable mode when the movable component is in a non-predetermined position. In the non-predetermined positions, the moveable component will not appropriately block or not block flow channels in the device in a predetermined manner. As a result, when in a non-predetermined position, the device may either provide an aerosol that has not been predetermined by the manufacturer, or not provide an aerosol at all. This would lead to a poor user experience. As such, the safety of the device and the resulting user experience is improved by preventing operation of the device when the moveable component is not in a predetermined position (i.e. is in a non-predetermined position). Non-predetermined therefore means non-predetermined by the manufacturer when the device is designed and provided for use.

[0072] In some examples, the moveable component is arranged to provide tactile feedback when in a predetermined position. In this way, the user may be informed when the moveable component is in a predetermined position and can be expected to operate in a predetermined manner. As the movement of the moveable component affects the aerosol provided by the device, inaccurate positioning of the moveable component may result in poor aerosol delivery, whether by inaccurate blocking of flow channels or poor alignment of electrical connections or the like. As such, the user experience of the device may be improved by providing some form of feedback to the user when the moveable component is in a predetermined position. Such an arrangement also increases the reliability of the overall device. The feedback may be tactile, this may be provided by an arrangement of projections and recesses (the tactile aspect of a projection slotting into the recess), or may be electrical, for example a sensor may provide a visual or audible indication when the moveable component is in a predetermined position.

[0073] In some examples, the device has a device housing for housing the components of the device. The housing may comprise indicators indicating locations of the predetermined positions. Such indicators may be graphics on the housing that may be arrow heads, which can be aligned with indicators on the moveable component. In this way, the user may be informed as to where the predetermined positions are and thereby be discouraged from moving the moveable component beyond the predetermined positions. This reduces the likelihood of damage to the device and therefore increases the lifetime of the device. Such indicators also decrease the likelihood of the device being put in a non-predetermined position and therefore being in an inoperable mode. In this way, the user experience is also improved.

[0074] In a specific example, in a first predetermined position, a first flow channel is partially blocked and may not allow a first aerosol to be provided to a user. In a second predetermined position, the first flow channel is not partially blocked and allows a first aerosol to be provided to a user. In a third predetermined position, a second flow channel (to, through and from a second aerosol generating material containing region) is not partially blocked and allow a second aerosol to be provided to a user. In a non-predetermined position between the second and third predetermined positions, both flow channels may be partially open and therefore the device may provide a combined first and second aerosol to a user. If the user is not expecting such an aerosol, it may decrease the user experience of the device. As such, in non-predetermined position the device may be arranged to not be able to provide an aerosol, i.e. be in an inoperable mode. This assists against an unexpected, and potentially low quality, aerosol being provided to the user and decreasing user experience.

[0075] In some examples, in the first position, the moveable component is arranged to block airflow through at least one flow channel. The moveable component may be arranged to entirely block the airflow through the flow channel by, for example, preventing airflow from the inlet 102 into the first aerosol generating material containing region 110 (numerals as per Figure 2). The moveable component may be arranged to entirely block the airflow through the flow channel by, for example, preventing airflow from the first aerosol generating material containing region 110 to the outlet 104 (numerals as per Figure 2). The same holds for the second aerosol generating material containing region 120. Accordingly, the viewing window is moved over a portion of the relevant aerosol generating material containing region during movement.

[0076] In some examples, the device 100 may have a series of inlets. By moving the moveable component to block an inlet to, say, the first airflow channel, the moveable component 130 blocks a part of the air flow channel and entirely prevents airflow through the channel and therefore prevents an aerosol being provided to the user from the first aerosol generating region 130 from the outlet 104. Entirely blocking the airflow channel also prevents an aerosol being provided to the user, for example, by blocking the inlet, the opening to an aerosol generating region, the outlet from the aerosol generating region and the outlet from the device.

[0077] In some examples, the moveable component may have an aperture which can be moved and aligned with apertures to the first and second aerosol generating material containing regions. When the aperture aligns with a specific flow path e.g. through the first aerosol generating material containing region or the second aerosol generating material containing region, airflow through that region is allowed and the region provides an aerosol that is provided from the outlet. In this way, a rotational movement may be able to provide blocking of certain flow paths while unblocking others. Similarly, the main body portion may have an aperture that may be aligned with an outlet from the aerosol generating material containing region. When aligned, that particular aerosol generating material containing region experiences a through flow of air and is able to provide an aerosol to the outlet of the device.

[0078] Each aerosol generating region and / or aerosol generating material containing region, may contain a flow detector or flow sensor such as a microphone or pressure sensor or the like that detects when a flow through the aerosol generating region occurs. In response to this, control circuitry may signal for a heater to activate to provide an aerosol from that aerosol generating region. The moveable component may move to block airflow past the flow sensor of the aerosol generating region not intended for use in that position, e.g. in the first position, the first flow path is blocked, the first aerosol generating region flow detector does not detect a flow and so the first aerosol is not provided. In contrast, moveable component may align an aperture with an inlet or outlet of the second aerosol generating region which means there is an airflow through the second aerosol generating region. The airflow is detected by the flow detector in the second aerosol generating region. This is detected and a signal sent to control circuitry. The control circuitry signals a heater to operate to form an aerosol from the aerosol generating material in the second aerosol generating region. This provides a robust and reliable device that is mechanically straightforward to construct and use.

[0079] A simple motion may be more user friendly for a movement-impaired user. The user wishing to use the device, change the flavour from the device, check the suitability of that aerosol generating material for use, and put the device in an inoperable mode, may desire a simpler motion, such as rotation of a portion of the device around a small number of degrees, such as between 30 and 90 degrees. In such some examples, rotating the moveable component of the device anticlockwise by 90 degrees renders the device useable (i.e. unlocks the device and selects a first flavour) and rotating a portion of the device clockwise 90 degrees renders the device temporarily un-useable (i.e. locks the device). As such, a less complex motion may improve user experience of the device.

[0080] In contrast, a more complex motion, such as squeezing a portion of the device and then rotating may be more difficult for an inappropriate user to perform, thereby decreasing the likelihood of inappropriate users being able to use the device. This may however impact the appropriate user’s user experience of the device. Combinations of motions such a squeeze and rotate, or translate then rotate are more difficult to replicate and are less likely to occur during, e.g., normal motion associated with the device for example when being carried in luggage during travel. As such, a more complex motion also has improved resistance to accidental motion changing the device from inactive (locked) to active (unlocked, with first or second flavour selected) states.

[0081] The device herein therefore provides a simple mechanical solution for selection of flavour and observing the suitability of that aerosol generating material, in a device that is easy to manufacture, very hygienic and robust during periods of use and non-use. The device is therefore cheaper to produce, reliable during use and non-use and accordingly provides an improved user experience.

[0082] In some examples, the device further comprises control circuitry arranged to prevent activation of the aerosol provision device when either the moveable component is not in a predetermined position, or the moveable component is in a predetermined position that is a locked position or a predetermined inoperable position. In use, the user may be able to move the movable component to a number, or series, of predetermined positions.

[0083] A “predetermined position” is used herein to refer to a position that is intended, by the manufacturer, to provide a predetermined outcome from the device. That outcome may be the provision of a specific aerosol from a specific region within the device, such as a first aerosol from an aerosol generating material contained in a first aerosol generating material containing region, or a second aerosol from a second aerosol generating material contained in a second aerosol generating material containing region, or a locked effect wherein the device cannot be used. In contrast, a “non-predetermined position” is used herein to refer to a position that is not intended by the manufacturer to provide a predetermined outcome from the device. This may be, for example, one or more positions that are between, or beyond, predetermined positions, as discussed with reference to Figure 4.

[0084] As also discussed with reference to Figure 4, in some examples, the device may further comprise a stopper to prevent the moveable component moving beyond the predetermined positions. The stopper may therefore provide further control over the positioning of the moveable component. In particular, the stopper may be a physical element that physically opposes attempts to move the moveable component beyond the range of predetermined positions. In another example, the stopper may be an electrical and / or magnetic component that electrically / magnetically opposed attempts to move the movable component beyond the range of predetermined positions.

[0085] Referring now to Figures 5 and 6, Figures 5 and 6 show a cross-sectional view of a device 400, 500. The device 400, in Figure 5 has a housing 410 that holds a first aerosol generating material containing region 420 and a second aerosol generating material containing region 430. Each region may have an aerosol generating material store, such as a reservoir, chamber, cage or the like. The device 400 has a heater 440 located so that the heater 440 can heat a region. The moveable component may be connected to the reservoirs such that the moveable component can be moved and, in turn, move the reservoirs in a direction shown by arrow D. By rotating the reservoirs, the user can control which reservoir is close to the heating element 440. This may be alongside movement of an aperture (or the like) to align with an airflow path to allow airflow through a specific aerosol generating region.

[0086] In this way, the heating element 440 may be arranged to provide an aerosol from the first aerosol generating region 420 and the second aerosol generating region 430, dependent on the movement provided by the moveable component to the reservoirs. As such, a device according to the present disclosure may have only one heating element for more than one reservoir.

[0087] In use, moving the moveable component rotates the first aerosol generating material containing region 420 towards the heater 440. The viewing window (which may be stationary in this instance) is over a portion of the first aerosol generating material containing region 420 when the first aerosol generating material containing region 420 is over the heater 440. In this way, the device ensures that the user has good visibility of the aerosol generating material containing region before activating the device 400. Relative movement between the window and the aerosol generating material containing regions in the device is sufficient to provide the benefits described herein.

[0088] In a similar example, shown in Figure 6, the device 500 may have an aerosol generating material reservoir 505 with at least two portions 520, 530. In the example shown, a first portion 520 of the aerosol generating material reservoir 505 is in the first aerosol generating material containing region. In the example shown, a second portion 530 of the aerosol generating material reservoir 505 is in the second aerosol generating material containing region.

[0089] The arrangement shown has the portions 520, 530 as two sides of a cylindrical aerosol generating material reservoir 505. The materials in the two portions 520, 530 of the reservoir 505 may be two different materials. The materials may be liquids or solids. In this arrangement, the device 500 may provide only one heater 540 thereby reducing the cost of production against a device with multiple heaters. This also advantageously provides a reduction in the electronic complexity of the device 500.

[0090] In some examples, the first portion 520 of the reservoir 505 may hold around 0.01 ml of liquid aerosol generating material. The first portion 520 may hold up to 0.02 ml or up to 0.03 ml of liquid aerosol generating material. The reservoirs may hold liquid up to 200 ml for multi-use or refillable, re-useable devices. The second portion 530 of the reservoir 505 may hold the same or a different volume of liquid to the first portion 520. The device 500 may be a single puff device 500 or a device 500 that is intended to be a disposable device 500, i.e. a device that is designed not to be re-fillable, rather once the reservoir or reservoirs are empty the device 500 may be disposed. The same can be applied to any of the examples herein regarding volume of reservoir in an aerosol generating region or aerosol generating material containing region.

[0091] By rotating the moveable component in the direction of arrow E, one or the other liquid reservoir 520, 530 may be moved to align with a flow path through the device. The heater 540 may remain stationary. As the reservoir arrangement is rotated, one reservoir is moved to be closer to the off-centre heater, such that that reservoir is the active, selected, reservoir from which an aerosol is provided.

[0092] In a disposable device, the power source (for powering the heater or heating element associated with one or more aerosol generating regions) may be non-rechargeable and non-replaceable. In this instance, the access to the power source portion is advantageous as the user may safely dispose of the power source once the device is suitably depleted. The power source may be arranged to have sufficient power to aerosolise the amount of aerosol generating material in the device, but not more. In this way, when the aerosol generating material has been aerosolised, the device has no remaining power and can be disposed of. This may improve the user experience, by providing a device that is easy to use and requires no maintenance.

[0093] In some examples, the device may have a first aerosol generating material reservoir and a second aerosol generating material reservoir. In such some examples, the first aerosol generating material reservoir may be in the first aerosol generating region and the second aerosol generating material reservoir may be in the second aerosol generating region. In this sense, the reservoirs may be separated by some distance. In this example, the first and second reservoirs may hold around 0.01 ml of liquid aerosol generating material, up to 0.02 ml of liquid aerosol generating material or up to 0.03 ml of liquid aerosol generating material. Alternatively, for a multi-use or refillable, re-useable device the reservoirs may hold far greater volumes, up to 200 ml.

[0094] As mentioned above, in some examples, the first flow channel and second flow channel may be entirely distinct from each other. In this example, the device may be more mechanically complex to construct and may require additional electronics such as puff sensors and heaters (though not necessarily), there is a reduced likelihood of a mixed aerosol being provided to a user. In this way, by isolating the flow channels from one another, there is reduced likelihood of a previous aerosol impacting the present aerosol, by for example having condensed on the channel inside the device. As such, the reliability and consistency of the aerosol provided to a user is improved.

[0095] In some examples, the separated flow channels may have an aerosol provided by one heater. The heater may be centrally located (as per either Figs 5 or 6) and moved, relatively, to within thermal communication of the aerosol generating material containing regions individually. The heater may be activated and one reservoir may have airflow through it such that one aerosol is provided to a user. In another example, the device may have a plurality of heaters, each of which may be activated by a specific predetermined position and corresponding electrical connection. A first heating element may be arranged to provide an aerosol from the first aerosol generating material in the first aerosol generating material containing region and a second heating element arranged to provide an aerosol from the second aerosol generating material in the second aerosol generating material containing region. While more costly to provide more heating elements and more complex electrical circuitry, the arrangement of the heating elements and the aerosol generating regions is made simpler. In either arrangement, one or more puff sensors may be used.

[0096] The process of moving the moveable component alters a physical and / or electrical arrangement within the device. The physical arrangement may refer to the physical arrangement of air flow channels through the device. The electrical arrangement may also or alternatively refer to the physical arrangement of electrical contacts in the device.

[0097] Any of the elements in the device may be arranged to be moved by the moveable component. In the above examples we have referred to moving and aligning apertures for flow paths or moving heaters or reservoirs the like. Movement of a central portion of the device, such as a portion abutting the mouthpiece has been found to be very user friendly and can be performed with one hand. The devices disclosed herein may be arranged to be easily manipulated (by simple slide, squeeze and slide, rotate, or squeeze and rotate motions) and therefore can be used by users with reduced mobility (specifically movements that can be performed one handed by the hand holding the device).

[0098] Movement of the moveable component may additionally or alternatively be performed with a hand, or with a small tool or coin such as turning a screw or the like. By slightly increasing the difficulty of moving the moveable component, the likelihood of an inappropriate user using the device is reduced significantly. Movement of the moveable component of the device can therefore lead to a change in aerosol and / or locking of the device. This provides a great level of control over their device thereby increasing user experience. In some examples, the moveable component may be moved in a manner that is not rotation around a longitudinal axis of device, such as by a pushing motion into (or from) a predetermined position.

[0099] Mechanical movements provided by the user have been discussed herein. The moveable component may be moved by an electrical signal provided by the user to the device via an interface. The signalling may be controlled by control circuitry in the device. By inputting a specific flavour selection, the control circuitry may provide signals to the moveable component to move and select the specific flavour. In this example, the moveable component is, in use, moved by electronic control circuitry of the aerosol provision device. In this way, while more costly than mechanical movement from the user, the likelihood of over movement of the moveable component - for example past a stopper - is reduced. In this example, therefore, the safety of the device is increased and accordingly the lifetime of the device.

[0100] Referring now to Figure 7, there is shown an example of an aerosol provision device 600 according to some examples. The device is similar to the devices of Figures 2 and 3, with similar components shown with their numerals starting with “6” as compared to “1” and “2” for Figures 2 and 3 respectively. For example, the device 600 has the same function as the device 100 from Figure 2 and the device 200 from Figure 3. Some components will not be discussed in detail but provide the same function as those discussed in detail in those Figures.

[0101] The moveable component 630 has a main body portion 632, a transparent / translucent portion 634 and an end portion 636. The transparent / translucent portion 634 and end portion 636 are within a housing portion 605a of the device 600. The housing 605a, 605b covers certain elements of the device 600, this may increase safety and assist in providing a space for including a mechanical arrangement for the components within the device 600. The main body portion 632 is not contained within a housing. As such, the user is able to directly grip and move the main body portion 632. The user is therefore able to move the moveable component 630 via the main body portion 632. The housing 605a, 605b may have a transparent portion 605a. During movement of the moveable component 630, the window 634 is aligned with a aerosol generating material containing region 610, 620 to show the remaining aerosol generating material within. This also prepares the device for providing an aerosol from that aerosol generating material. The user is able to see through the transparent / translucent housing portion 605a, through the aligned window 634 to the relevant aerosol generating material containing region. This allows the user to decide whether to activate the device 600 to provide an a aerosol. In some examples, the user is to rotate the main body portion 632 as per arrow F.

[0102] In doing so, the user is also able to move the cap portion 636 within the housing. The cap portion may contain an aperture or the like that can be aligned, via the rotation, with openings to the first aerosol generating region 610 or second aerosol generating region 620. In this way, the user is also able to alter flow paths or the like to select either the first aerosol generating material containing region 610 or second aerosol generating material containing region 620 for providing an aerosol for inhalation.

[0103] Any device herein may additionally include components such as a power portion comprising a power source for providing power to the aerosol generating regions to activate heaters or the like.

[0104] The first flow channel or second channel may share a portion of the flow channels, such as the inlet 602 and / or outlet 604. Alternatively they may be entirely separate having different inlets and outlets.

[0105] Referring to Figure 8, there is shown an example of a consumable. The consumable 700 comprises a first aerosol generating material containing region 710 first aerosol generating material containing region 712. The consumable 700 comprises a second aerosol generating material containing region 720 arranged to contain a second aerosol generating material 722. The consumable 700 comprises a moveable component 730 arranged to move between a number of predetermined positions comprising at least a first and a second position. The moveable component 730 comprises a transparent and / or translucent portion 732.

[0106] The example shown in Figure 8, shows the moveable component in one of the predetermined positions. In the predetermined position shown (the second predetermined position), the transparent and / or translucent portion is arranged over a portion of the first aerosol generating material containing region. In this way, the user is able to view the level of the aerosol generating material within the first aerosol generating material containing region 710. When the moveable component 730 is moved to the first predetermined position, the transparent and / or translucent portion is arranged over a portion of the second aerosol generating material containing region. In this position, the user would be able to view the level of the aerosol generating material within the second aerosol generating material containing region 720.

[0107] In examples, the consumable 700 may comprise at least one heater for generating a first aerosol from aerosol generating material 712 contained in the first aerosol generating material containing region 710 and for generating a second aerosol from aerosol generating material 722 contained in the second aerosol generating material containing region 720. The consumable 700 has a moveable component 730 that may be moved in the direction of the arrow A. This movement may be via rotation of the like around a central axis of the consumable 700. In moving the moveable component 730 along the arrow A, the moveable component 730 may be moved from a first position to a second position.

[0108] The example shown in Figure 8 shows a consumable 700 with a moveable component 730 that may be inserted into an aerosol provision device or an aerosol provision system or the like. The moveable component 730 is moved as per earlier examples and allows a user to show an aerosol generating material to the user from within the device or system. This improves ease of use for a user as the user can know whether or not the device or system has a first aerosol generating material prior to requesting an aerosol from that material.

[0109] Referring now to Figure 9, there is shown a flow chart of a method of providing an aerosol for inhalation. The method is for use in an aerosol provision system or aerosol provision device. The method 800 has steps 805, 810, 815, 820. In step 805, a first aerosol generating material containing region is provided and arranged to contain a first aerosol generating material. In step 810, a second aerosol generating material containing region is provided and arranged to contain a second aerosol generating material. These may be provided in the form of a device, system or consumable.

[0110] In step 815, a moveable component comprising a transparent and / or translucent portion is provided. The moveable component when in a first position is arranged such that the transparent and / or translucent portion is arranged over a portion of the second aerosol generating material containing region. In this way, when moved to the first position a portion of the second aerosol generating material containing region can be seen by the user. As noted above, this may reveal the aerosol generating material contained in the second aerosol generating material containing region.

[0111] In step 820, the moveable component when in a second position is arranged such that the transparent and / or translucent portion is arranged over a portion of the first aerosol generating material containing region. In this way, when moved to the second position a portion of the first aerosol generating material containing region can be seen by the user. In this way, by moving the moveable component the user can be shown whether there is or is not aerosol generating material within the selected aerosol generating material containing region. If the user notes that there is aerosol generating material in the aerosol generating material containing region the user can continue to use the device (or system) and be provided with an aerosol from that aerosol generating material. Conversely, if the user notes that there is no aerosol generating material in the selected aerosol generating material containing region, the user does not activate the device (or system) which can avoid bum out of components within the device (or system). As such, it is advantageous to provide a moveable component that selectively reveals portions of the aerosol generating material containing regions in the consumable (or device or system).

[0112] The power portion (or power source portion) may be connected to the aerosol generating regions by electrical connections. These may be moved as part of moving the moveable component in any of the examples above. Moving the moveable component relatively to the device may move the electrical contact or electrical contacts connected to the first aerosol generating region (related as noted above to the first aerosol generating material containing region) and the second aerosol generating region (related as noted above to the second aerosol generating material containing region) to the contact or contacts of the power portion. The first aerosol generating region may be in fluid communication with the first aerosol generating material containing region such that an aerosol can be provided from the aerosol generating material in the first aerosol generating material containing region by the first aerosol generating region. The equivalent holds for the second aerosol generating region and the second aerosol generating material containing region.

[0113] Moving the moveable component allows a user to align the contacts of the power portion with any of: the electrical contacts of the first aerosol generating region; the electrical contacts of the second aerosol generating region; and not connect to either contacts of the first aerosol generating region or the second aerosol generating region, such that one or another region can provide an aerosol for inhalation, or the device can be placed in a locked state where neither region provides an aerosol for inhalation. The contacts may be slidable contacts. In this way, the contacts may be moved to slide along a face and connect with the contacts of the power portion when the respective contacts are aligned. The contacts may be contact brushes, or the like, to assist sliding and electrical connection. The contacts may be moved into alignment with contacts of the power portion. In another example, either contact or contacts may be a conductive trace which can be contacted by contact brushes or pins or the like. In some examples, the power portion contacts may be recessed and the contacts of the first aerosol generating region and the second aerosol generating region may comprise a resilient member to bias the brushes or pins or the like into the recesses holding the contact or contacts of the power portion. In this way, a reliable and robust electrical connection can be provided after moving the moveable component into a predetermined position.

[0114] In a predetermined position, the moveable component may unlock the power source portion. The power source portion may comprise a battery, control circuitry, puff detectors, microphones or the like for accurately initiating heating from suitable aerosol generating regions during inhalation. Unlocking the power source portion may improve ease of repair for a manufacturer or designated engineer for the device. In this way, the lifetime of the device may be improved.

[0115] In some examples, in a predetermined position, the moveable component may unlock the power source portion to provide access to the power source portion for removing a power source from and / or inserting a power source to the power source portion. Providing a user with access to the power source for removing and replacing a power source improves the ease with which the battery can be removed, recharged and / or replaced. This in turn increases the lifetime of the device over a device without access to the power source portion. Furthermore, during disposal of the device a user may be able to access the power source portion remove the elements therein (power source, electronics etc), and recycle the elements in a suitable way, while recycling the body of the device in another suitable way. As the body of such devices are often made from different materials (plastics etc), this reduces the environmental impact of disposal of the device. In use, the user is able to move the moveable component, remove a portion of the device near the power source portion (e.g. a bottom of the device), slide components out of the device (e.g. circuit boards, PCBs, batteries, microphones etc) and recycle as electronics while the remaining device is recycled as plastics.

[0116] While locking the power source from the user may be safer from one perspective, user access can be offered to a user to improve the disposal of the device from an environmental perspective. This counterintuitive approach therefore leads to significant advantages.

[0117] Furthermore, by using the same moveable component to lock, unlock, select aerosols, and recharge / dispose of electronics within the device, a robust, reliable, reduced complexity for manufacture and use, multi-purpose approach which results in extremely high user satisfaction is provided by delivering a device with multiple aerosol provision options that has an improved lifetime.

[0118] Different movements may be provided to the moveable component for changing operable states of the device compared to access of the battery portion to increase the difficulty for inappropriate users to access sensitive components of the device. For example, the user may:

[0119] Rotate to change aerosols;

[0120] Squeeze and rotate to lock the device; and,

[0121] Squeeze and push (translate) the moveable component to access the power portion.

[0122] Each of these are simple movements for an appropriate user, but the use of multiple movements decreases the likelihood of an inappropriate user accessing the device.

[0123] In many of the above examples, the moveable component is arranged to move around a longitudinal axis of the device. Rotational movement has been found to be mechanically simple for users. In particular, rotational movement of the body portion of the device has been found to be achievable even for users with movement difficulties. The rotation of a body portion may occur while holding the device, such that a movement using only one hand can move the moveable component and change the aerosol provided to the user. In some examples, the moveable component is, in use, moved by a user of the aerosol provision device. In this example, the user moves the moveable component via a mechanical motion. This is a cost- effective way of using user motion to control aerosol delivery alongside lock the device and access the battery of the device. Alternatively or additional other movements may be arranged to select between aerosols.

[0124] The arrangements discussed herein may use single or multiple puff sensors, flow sensors or the like. By ensuring, the flow paths (whether entirely separate or overlapping in some portion) impact the area near the puff sensor, only one puff sensor need be used. In this way, fewer electronics can be used in the manufacture of the device and the overall cost is decreased. Such a device can then be provided to users for a lower price.

[0125] As such, there has been described a device for providing an aerosol to a user that provides great control to the user while requiring only limited mechanical movement or dexterity from the user.
