Technical Field

The present invention relates to an aerosol provision device.

Background

Aerosol provision devices and systems are known. Common systems use heaters which 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. Users may wish to personalise the aerosols provided by aerosol provision devices. It can be desirable for the user to control the aerosol provided. This may increase the user experience of the device.

The present invention is directed toward solving some of the above problems.

Summary

Aspects of the invention are defined in the accompanying claims.

In accordance with some embodiments described herein, there is provided an aerosol provision device, comprising: at least one outlet through which aerosol within the device can pass; an aerosol generating portion comprising a first aerosol generating region arranged to generate a first aerosol and a second aerosol generating region arranged to generate a second aerosol; a power portion configured to supply power to the aerosol generating portion; and a movable component arranged to provide relative movement between the aerosol generating portion and the power portion, such that when the movable component is in a first position at least the first aerosol is supplied to the at least one outlet, and when the movable component is in a second position at least the second aerosol is supplied to the at least one outlet.

Such an arrangement is able to provide a user of the aerosol provision device control over the provision by the device of a first or a second aerosol. In particular, the arrangement allows a single device to provide a variety of aerosols for enjoyment by a user. It is therefore possible for a user to personalise their device and reduce the number of devices or additional material required to provide the full range of aerosols a particular user may desire. This arrangement advantageously requires less material to provide this outcome (only one rather than several devices required) and also significantly improves user experience over previous systems.

The aerosol provision device of the present invention is able to be manipulated by a user to provide an aerosol from a specific aerosol generating region. The manipulation is far less intensive than requiring a user to change the aerosol generating material within the device and therefore provides a far more robust, safe and easy-to-use solution than previous systems. The devices disclosed herein may operate via several different mechanisms, including physical manipulation of the airflow paths and manipulation of the electrical connections within the device.

The arrangement is therefore able to provide a “plug-and-play” approach. In that, the user may activate the device on first usage with a first aerosol generating material and then, with a minor physical movement, activate the device with a second aerosol generating material. The system disclosed herein is an improvement over previous systems due to the ease of use and removal of complex manipulations for changing between the aerosols provided by a device.

In particular, users that have limited or impaired mobility, in particular in relation to hands, are able to use the full capability of the device.

Detailed Description

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.

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. Figure la illustrates a schematic view of an example of an aerosol provision device 100 according to the present invention. The aerosol provision device 100 has at least one outlet 110 through which aerosol within the device 100 can pass. The aerosol provision device 100 has an aerosol generating portion 140 comprising a first aerosol generating region 120 arranged to generate a first aerosol and a second aerosol generating region 130 arranged to generate a second aerosol. The aerosol provision device 100 has a power portion 154 configured to supply power to the aerosol generating portion 140. The aerosol provision device 100 has a movable component 160 arranged to provide relative movement between the aerosol generating portion 140 and the power portion 154. The moveable component 160 is arranged such that when the movable component 160 is in a first position at least the first aerosol is supplied to the at least one outlet 110, and when the movable component 160 is in a second position at least the second aerosol is supplied to the at least one outlet 110.

The power portion 154 may comprise a power source or the like for providing power to the aerosol provision device 100.

The moveable component 160 may be a component that may be moved by rotation or translation. In use, the user may move the movable component 160 to a series of predetermined positions. 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 100. That outcome may be the provision of a specific aerosol from a specific region within the device 100, such as a first aerosol from the first aerosol generating region 120, or a second aerosol from the second aerosol generating region 130. 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 100. This may be, for example, one or more positions that are between, or beyond, predetermined positions.

The process of moving the moveable component 160 alters a physical arrangement within the device 100. The physical arrangement may refer to the physical arrangement of air flow channels through the device 100. The physical arrangement may refer to the physical arrangement of electrical contacts in the device 100. In an example, movement of the moveable component 160 alters the flow channels within the device 100. In the first position, the moveable component 160 at least partially blocks the first flow channel. In the second position, the moveable component 160 at least partially blocks the second flow channel. The first flow channel may be a flow channel that leads from an inlet, through the first aerosol generating region 120 to an outlet 110. The second flow channel may be a flow channel that leads from an inlet, through the second aerosol generating region 130 to an outlet 110.

A body portion 150 of the device 100 comprises the moveable component 160, the moveable component 160 arranged to provide relative movement between the aerosol generating portion 140 and the power portion 154.

In a predetermined position, the moveable component 160 at least partially blocks a flow channel between at least one inlet and at least one outlet of the device 100. The device 100 may have one or more inlets to allow air to enter the device 100. Flow channels may link the one or more inlets to one or more outlets of the device 100. By moving the moveable component, the user is able to block (partially or fully) one or more flow channels. In this way, the user is provided with control over the aerosol provided by the aerosol provision device 100.

In the example of Figure la, the moveable component 160 is part of the aerosol generating portion 140 and may be moved in the manner of arrow A. The moveable component 160 provides relative movement between the aerosol generating portion 140 and the power portion 154. In an example, the moveable component 160 may be part of the power portion 154. In an example, the moveable component 160 may be part of a mouthpiece of the device 100. The moveable component 160 may be moved to provide relative motion between any combination of the power portion 154, the aerosol generating portion 140 and a mouthpiece. In an example, the power portion 154 may be moved, e.g. rotated, while the aerosol generation portion 140 and a mouthpiece are not moved. In another example, the aerosol generation portion 140 and a mouthpiece may be moved, while the power portion 154 is not moved.

In an example, the moveable component 160 may be moved in a manner that is not rotation around a longitudinal axis of device 100, such as by a pushing motion into (or from) a predetermined position. Rotation in the direction of the arrow A, in the example of Figure la, moves the moveable component 160 to block one air flow path and open another air flow path such that one of the first aerosol generating region 120 or the second aerosol generating region 130 provides an aerosol to the outlet 110. In this way, the user is able to select which aerosol is provided to them, via a robust and reliable mechanical arrangement.

In the example of Figure lb, the moveable component 160 is part of the aerosol generating portion 140 and may be moved in the manner of arrow A. The arrangement of Figure lb is similar to the arrangement of Figure la, however the arrangement of Figure lb has one electrical connection to the power portion 154. Moving the moveable component 160 in the example of Figure lb relatively moves the electrical contact or electrical contacts connected to the first aerosol generating region 120 and the second aerosol generating region 130 to the contact or contacts of the power portion 154. Moving the moveable component 160 allows a user to align the contacts of the power portion 154 with one or the first aerosol generating region 120 and the second aerosol generating region 130, such that only one region can provide 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 154 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 154. 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 an example, the power portion 154 contacts may be recessed and the contacts of the first aerosol generating region 120 and the second aerosol generating region 130 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 154. In this way, a reliable and robust electrical connection can be provided after moving the moveable component into a predetermined position.

In an example, the moveable component 160 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 160 is affecting the aerosol provided by the device 100, inaccurate location of the moveable component 160 may result in poor aerosol delivery, whether by inaccurate blocking of flow channels or poor electrical connections or the like. As such, the user experience of the device 100 may be improved by providing some form of feedback to the user when the moveable component 160 is in a predetermined position. Such an arrangement also increases the reliability of the overall device 100. The feedback may be tactile, this may be provided by an arrangement of projections and recesses, or may be electrical, for example a sensor may provide a visual or audible indication when the moveable component 160 is in a predetermined position.

In an example, the device 100 may further comprise a stopper to prevent the moveable component 160 moving beyond the predetermined positions. The stopper may be a physical element that physically opposes attempts to move the moveable component beyond the range of predetermined positions.

In the example of Figure 2, there is shown an arrangement 200 of a stopper for preventing a moveable component moving beyond predetermined positions. In the example of Figure 2, the arrangement 200 has an aerosol provision device housing 210. Within the housing 210 is an array of predetermined positions 220. The array of predetermined positions 220 has a first predetermined position 222, a second predetermined position 224, a third predetermined position 226, and a fourth predetermined position 228. The moveable component may have a projection that enters a recess located at each of the predetermined positions 220. The moveable component may have a resilient member arranged to extend into a recess at a predetermined position 220 when suitably aligned, or arranged to bias a projection (or electrical contact) into a recess when suitably aligned.

In these examples, the user is able to safely, reliably and easily move the moveable component into a predetermined position 220. The arrangement 200 has a pair of stoppers 230. The stoppers 232, 234 prevent the moveable component moving beyond the predetermined positions 220. The stoppers 232, 234 may physically 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 230 may be arranged adjacent, or reasonably proximal to, the outermost predetermined positions 222, 228 (in the example of Figure 2). Use of a stopper, or stoppers, improve the overall safety of the aerosol provision device disclosed herein. The stoppers 230 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 an example the stoppers 230 may prevent movement beyond around 180 degrees of the moveable component. The stoppers 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.

In an example, 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. In this example, the moveable component may be moved to a third position (such as 226 from Figure 2). 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 228.

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. While in one of these modes, the user cannot receive an aerosol from the device without changing the mode, by moving the moveable component into a different predetermined position. A predetermined position may be a latched position. In the example of Figure 2, there are positions between the predetermined positions indicated 220, such as position 240. In the present disclosure, the position 240 is not considered a predetermined position 220 as the moveable component will not latch into place in position 240. 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.

In an example, 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 align flow channels or electrical components (or the like) 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.

In a specific example, in a first predetermined position, a first flow channel is open and allows a first aerosol to be provided to a user. In a second predetermined position, a second flow channel is open and allows a second aerosol to be provided to a user. In a non-predetermined position between the first and second 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.

In an example, the device has a mouthpiece, wherein the mouthpiece comprises at least one outlet. The mouthpiece may provide a suitable contact point for a user’s mouth to receive an aerosol from the device. The mouthpiece may have one or more outlets in the mouthpiece. The mouthpiece may therefore have a series of outlets from which different aerosols may be provided to a user.

In an example, the first flow channel and second flow channel share at least one portion of flow channel. In such an example, there is some overlap between the two flow channels. In an example, the flow channels may join at an inlet or an outlet. By sharing some portion of flow channel, the device may be made more compact and therefore easier to transport for a user. Sharing a portion of the flow channel also means that duplicate components, such as multiple outlets, are not required. In certain examples, the shared flow channels may have shared electronic components such as puff detectors or the like, which reduces the overall cost of the device. In an example, the device has a heating element for providing an aerosol, the heating element arranged to provide an aerosol from the first aerosol generating region and the second aerosol generating region. In such an example, the heating element is arranged to provide thermal energy to both the first aerosol generating region and the second aerosol generating region.

Such an example is shown in Figure 3. Figure 3 shows a cross-sectional view of a device 300. The device 300 has a housing 310 that holds a first aerosol generating region 320 and a second aerosol generating region 330. Each region may have an aerosol generating material store, such as a reservoir or the like. The device 300 has a heater 340 located so that the heater 340 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 B. By rotating the reservoirs, the user can control which reservoir is close to the heating element 340. In this way, the heating element 340 may be arranged to provide an aerosol from the first aerosol generating region 320 and the second aerosol generating region 330, dependent on the movement provided by the moveable component to the reservoirs. Alternatively, the heater 340 may be centrally located and be operated to affect both regions simultaneously. In such an arrangement an air flow path through a region may be closed by the moveable component, such that aerosol generated by the heater is not provided to the user. Heated aerosol may re-condense after a period of time has elapsed - in this instance, the moveable component may move the reservoir e.g. up and down within the device 300 to be within the impact of the heater 340 or away from the heater 340 as well as altering the flow channels within the device 300.

In an example, shown in Figure 4, the device 400 may have an aerosol generating material reservoir 405 with at least two portions 420, 430. In the example shown, a first portion 420 of the aerosol generating material reservoir 405 is in the first aerosol generating region. In the example shown, a second portion 430 of the aerosol generating material reservoir 405 is in the second aerosol generating region. The arrangement shown has the portions 420, 430 as two sides of a cylindrical aerosol generating material reservoir 405. The materials in the two portions 420, 430 of the reservoir 405 may be two different materials. The materials may be liquids or solids. In this arrangement, the device 400 may provide only one heater 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 400.

In an example, the first portion 420 of the reservoir 405 may hold around 0.01 ml of liquid aerosol generating material. The first portion 420 may hold up to 0.02 ml or up to 0.03 ml of liquid aerosol generating material. The second portion 430 of the reservoir 405 may hold the same or a different volume of liquid to the first portion 420. The device 400 therefore may be a single puff device 400 or a device 400 that is intended to be a disposable device 400, i.e. a device that is designed not to be re-fillable, rather once the reservoir or reservoirs are empty the device 400 may be disposed. In a disposable device 400, the device 400 may have a power source that is contained within the power portion that cannot be accessed by a user. The power source may be non-rechargeable and non-replaceable. 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 400 is 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.

In contrast to the example of Figure 4, the device may have a first aerosol generating material reservoir and a second aerosol generating material reservoir. In such an example, 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.

In an example, 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. In an example, the separated flow channels may have an aerosol provided by one heater. The heater may be centrally located and within thermal communication of the aerosol generating material reservoirs. 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 region and a second heating element arranged to provide an aerosol from the second aerosol generating 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.

In an example, the moveable component is arranged to move around a longitudinal axis of the device, as shown in Figures la and lb. 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 an example, 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.

In another 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.

In an example, 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.

Referring now to Fiure 5, there is shown a portion of an example of a device 500. The Figure shows a switch 510 on the device 500. The switch may be on a bottom end 505 of the device 500. The switch 510 can be moved as shown in the three cross-sectional views of Figure 5. The switch 510’ is shown in a predetermined position wherein the left flow channel is closed and the right flow channel is open. In this position, airflow shown by arrow C can enter the right flow channel. The switch 510” is shown in a predetermined position wherein both left and right flow channels are closed. The switch 510’” is shown in a predetermined position wherein the right flow channel is closed and the left flow channel is open. In this position, airflow shown by arrow D can enter the left flow channel.

In the position of 510”, the device is in an inoperable mode as air cannot enter the device 500. In this arrangement, the device 500 can stand on the bottom end 505 of the device 500, as the switch does not project beyond the recess within which it is set in the bottom end 505. As such, this arrangement advantageously prevents the user standing the device 500 when the device 500 is operable. In this way, the user has a noticeable reminder that the device 500 is in an operable mode - by the device 500 not being able to rest on the bottom end 505, when placed on a surface.

Referring now to Figure 6, there is shown an example of a device 600. The device 600 has a housing 610 and a cover 620. The cover 620 may be a removable cover for removably covering an outlet. This cover 620 may improve the cleanliness of the device 600 by protecting the device 600 from particle ingress via the outlet.

In an example, the removable cover 620 is arranged to support the device 600 when located on a flat surface. The removable cover 620 may therefore act as a stand or the like for the device 600. The cover 620 may have a substantially flat end surface for allowing the device 600 to be balanced on the cover 620. The cover 620 may have a series of teeth or projections or the like on which the device 600 may stand when on a flat surface. The cover 620 is therefore capable of supporting the device 600.

Referring now to Figure 7, there are a series of covers shown covering a mouthpiece of the aerosol generating device. The cover 720 is shown covering a mouthpiece and is in a good fit to the housing 710 of the device. The cover 720’ is shown with a flat end surface 721’and can therefore allow a user to stand the device on the surface 721’ (as described above), other arrangements are capable of proving this as noted above. The cover 720” is shown with a housing connection 722” for connecting to a housing 710” of the aerosol provision device. The cover 720 may be capable of rotating around the housing connection 722”. This rotation may be enjoyable for a user. The rotation also allows the device to be rested on the flat end 721” of the cover 720 in a variety of arrangements. In an example, the housing connection 722” is half way along the device and therefore the cover 720” can free spin around the full body of the device.

Referring now to Figure 8, there are a pair of covers shown covering a mouthpiece of the aerosol generating device. In an example, the cover 820 is a slideable cover 820 for slideable covering the outlet (or a mouthpiece). In an example, the cover 820 may be slid up and down the housing 810 to uncover 820’ and cover 820 the outlet. The cover 820 may be a sleeve or the like that can be moved by a user. The sleeve 820 may be moved by a handle 822 or lever or the like to move the sleeve 820.

In an example, the slideable cover 820, 820’ is arranged to slide between at least two positions (two positions are shown in Figure 8), wherein in a first position the slideable cover 820 covers the outlet; and, wherein in a second position the slideable cover 820’ does not cover the outlet.

The power electronics of the device may include a power source such as a battery or the like alongside control circuitry for controlling the activation and use of power in the device 100. The control circuitry may communicate with a microphone or other puff sensor or the like and control heating of the heating elements in the device. 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.

In a particular example, the device disclosed herein may operate with a flavour pod which is replaceable in the device - this may be referred to as a consumable. The flavour may be any of tobacco and glycol and may include extracts (e.g., licorice, hydrangea, Japanese white bark magnolia leaf, chamomile, fenugreek, clove, menthol, Japanese mint, aniseed, cinnamon, herb, wintergreen, cherry, berry, peach, apple, Drambuie, bourbon, scotch, whiskey, spearmint, peppermint, lavender, cardamon, celery, cascarilla, nutmeg, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, cassia, caraway, cognacjasmine, ylang- ylang, sage, fennel, piment, ginger, anise, coriander, coffee, or a mint oil from any species of the genus Mentha), flavour enhancers, bitterness receptor site blockers, sensorial receptor site activators or stimulators, sugars and/or sugar substitutes (e.g., sucralose, acesulfame potassium, aspartame, saccharine, cyclamates, lactose, sucrose, glucose, fructose, sorbitol, or mannitol), and other additives such as charcoal, chlorophyll, minerals, botanicals, or breath freshening agents. They may be imitation, synthetic or natural ingredients or blends thereof.

When combined with an aerosol generating medium, the aerosol provision device as disclosed herein may be referred to as an aerosol provision system.

Thus there has been described an aerosol provision device, for providing an aerosol for inhalation by a user, comprising: control circuitry for controlling an activation state of the aerosol provision device; a detector arranged to detect an air output associated with a user of the aerosol provision device; wherein the control circuitry is arranged to update an activation state of the aerosol provision device in response to receiving a signal from the detector associated with an authorised user.

The aerosol provision system may be used in a tobacco industry product, for example a noncombustible aerosol provision system.

In one embodiment, the tobacco industry product comprises one or more components of a noncombustible aerosol provision system, such as a heater and an aerosolizable substrate. In one embodiment, the aerosol provision system is an electronic cigarette also known as a vaping device.
