Description

AEROSOL PROVISION SYSTEM
Technical Field The present invention relates to an aerosol provision system, an aerosol provision device, a method of providing an aerosol, and aerosol provision means.
Background Aerosol provision systems are known. Common systems use heaters to create an aerosol from an aerosol generating material which is then inhaled by a user. The aerosol generating material from which the aerosol is generated is consumed during use of the aerosol provision system. When an aerosol generating material is heated, the aerosol generating material may change structurally. Over time such structural changes may reduce the user experience of the aerosol provision system, by virtue of changing flavours or increasing difficulty of use as the aerosol generating material is depleted. Modern systems often use a predetermined time period of active use of a system to indicate depletion of aerosol generating material within the system. At this point, the aerosol generating material may be removed or the device replaced.
This can lead to increase cost of use of such a device.
The present invention is directed toward solving some of the above problems.

It should be understood, however, that the drawings and detailed description of the specific embodiments are not intended to limit the invention to the particular forms disclosed.
On the contrary, the invention covers all modifications, equivalents and alternatives falling within the scope of the present invention as defined by the appended claims.

described herein.

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. According to the present disclosure, a "non-combustible" aerosol provision system is one where a constituent aerosoli sable material of the aerosol provision system (or component thereof) is not combusted or burned in order to facilitate delivery to a user. 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''
3 and "vapour", and related terms such as "vaporise", "volatilise" and "aerosolise", may generally be used interchangeably.
In the example of Figure 1, an aerosol provision system 100 is shown. The aerosol provision system 100 has an aerosol provision device 110 and an aerosol generating component 120.
The aerosol provision device 110 has a power source 112 and a controller 114.
The aerosol provision device 110 is configured for engagement with the aerosol generating component 120. The aerosol generating component 120 has an aerosol generator 122 for generating an aerosol in use. The aerosol generating component 120 also has a pod 124 downstream of the aerosol generator 122. The controller 114 of the aerosol provision device 110 is configured to monitor a lifetime of the pod 124 and to facilitate modulation of the temperature experienced by the pod 124 over its lifetime.
The controller 114 may monitor the lifetime of the pod 124 by detecting the number of uses (e.g. puffs including length of puff for example) of the aerosol provision system 100 while the pod 124 has been active. The controller 114 may also detect the temperature at which the pod 124 is heated during periods of use. Higher temperatures may lead to a more rapid depletion of aerosol generating material and therefore a shorter lifetime for the pod 124.
The controller 114 may facilitate modulation of the temperature experienced by the pod 124 of its lifetime in a passive and/or active manner. In an example, the controller 114 may be configured to determine a temperature at the pod 124. This may be as a result of a thermal detector or sensor or the like which provides a reading of the temperature (or an associated characteristic) at the pod 124 to the controller 114.
The controller 114 may inform a user of the temperature of the pod 124. The user may then decide to alter the temperature experienced by the pod 124. The user may be able to control the temperature at which the aerosol provision system 100 operates (herein referred to as "operating temperature"). This may be via a user interface on the aerosol provision system 100, which may be electrical, or via a more mechanical manner such as changing the position of elements within the aerosol provision system 100. In this way, the controller 114 may passively facilitate modulation of the temperature experienced by the pod 124 over its lifetime.
4 The controller 114 may actively facilitate modulation of the temperature experienced by the pod 124 by, in an example, detecting the temperature of the pod 124 and providing a signal which results in an alteration of the temperature of the pod 124. This may be predetermined via a lookup table of suitable temperatures or the like. The controller 114 may optionally or additionally provide a signal which results in an alteration of the position of the pod 124 within the aerosol provision system 100. The controller 114 may control the heat profile produced in the system 100. This heat profile may be provided by the aerosol generator 422 or heaters/heating elements in the system 100.
The aerosol provision system 100 shown in the example of Figure 1 has an outlet for aerosol to exit the system 100. The aerosol generated by the aerosol generator 122 may flow past the pod 124 and through outlet 130 and then through outlet 140 to exit the aerosol provision system 100. A user may then inhale the aerosol provided. An outlet (or series of outlets) may enable fluid communication between the aerosol generator 122 of the aerosol provision system 100 and the environment external to the aerosol provision system 100.
In the example of Figure 2, an aerosol provision system 200 is shown. The example of Figure 2 is similar to the example of Figure 1. Where similar components are shown in both Figures 1 and 2, the numerals on Figure 2 used to refer to the similar component from Figure 1 have been increased by 100 for simplicity. For efficiency, these components may not be discussed in detail again here.
The aerosol provision system 200 has a region A within the aerosol provision system 200. In the example shown, the pod 224 is contained within the region A. The temperature of the region A will be indicative of the temperature experienced by the pod 224 within region A.
As such, controlling the temperature at the region A in which the pod 224 is located allows the controller 214 to control the temperature applied to the pod 224. The pod 224 may contain a flavour. The flavour may be aerosolisable such that heating the flavour produces an aerosol for inhalation.
The flavour may be distributed evenly within the pod 224. Flavour located closer to the external surface of the pod 224 will be affected by the thermal energy provided to the region A more early in the lifetime of the pod 224 than the flavour located deeper into the pod 224.
Once the flavour closer to the external surface of the pod 224 has been depleted or in some
5
6 other way used up, it is necessary to provide thermal energy to the flavour located more towards the centre of the pod 224. This portion of the flavour of the pod 224 may be referred to herein as the "deeper flavour" or "more centrally located flavour". A way to provide thermal energy to the more centrally located flavour is to increase the total thermal energy so that the thermal energy is able to penetrate further into the pod 224 to provide aerosolised particles from the flavour. This can be controlled by the controller 214 modulating the temperature experienced by the pod 224. This is likely, in use, to be increasing the temperature experienced by the pod 224.
In an example, the aerosol generator 222 provides an aerosol that entrains compounds from the flavour in the pod 224. The thermal energy provided to the pod 224 may be provided by the temperature of the aerosol generated in the aerosol generator 222. As such, the thermal energy of the aerosol in the region A is the thermal energy that may be transmitted to the pod 224. It is not likely that all the thermal energy in the region A will be transferred to the pod 224. Therefore, the controller 214 may modulate the temperature experienced by the pod 224 by controlling the temperature of the aerosol produced by the aerosol generator 222. This may involve operating a heater or the like at a higher temperature when generating the aerosol.
In the example of Figure 3, an aerosol provision system 300 is shown. The example of Figure 3 is similar to the examples of Figures 1 and 2. Where similar components are shown in both Figures 2 and 3, the numerals on Figure 3 used to refer to the similar component from Figure 2 have been increased by 100 for simplicity. For efficiency, these components may not be discussed in detail again here.
The controller 314 of the aerosol provision system 300 shown in Figure 3 is connected to a sensing element 316. The sensing element 316 may be part of the controller 314 or separate.
The sensing element 316 is connected to the controller 314 such that the sensing element 316 can send signals to the controller 314. The sensing element 316 may send signals in relation to temperature, resistance and/or position. The sensing element 316 may detect when the pod 324 is provided into the system 300 and provide a signal to the controller 314. The sensing element 316 may provide a signal to the controller 314 when the aerosol generating component 320 is engaged within the device 300. The controller 314 may detect an electrical connection between the aerosol provision device 310 and an aerosol generating component 320 within the system 300. The sensing element 316 may be in a wired or wireless connection to the controller 314.
The system 300 may be a modular system 300 with the sensing element 316 detecting when the aerosol generating component 320 is connected to the aerosol provision device 310.
Alternatively, the system 300 may be integral and the pod 324 may be inserted into the aerosol generating component 320. This insertion may be detected by the sensing element 316. In this way, the controller 314 may be informed when the pod 324 is first introduced into the system 300 and therefore from when to document the lifetime of the pod 324. The lifetime, as discussed above, will depend on usage.
In an example, the sensing element 316 is a temperature sensor or detector.
The temperature sensor 316 observes the temperature experienced by the pod 324 in the region A
and sends this measurement to the controller 314. The controller 314 can facilitate modulation of this temperature over the lifetime of the pod 324. The temperature sensor 316 may detect the temperature for example via IR radiation, use of thermocouples or the like.
Different users may have different usage characteristics (number of puffs in a session, regularity of sessions in a day, amount of aerosol desired etc.) and so a controller 314 for one user system 300 may control temperature differently from a controller 314 for a second user system 300. This provides a bespoke performance on a user by user basis.
In an example, that the controller 314 may signal an increase in the temperature by around 10% when 30% into the expected lifetime of the pod 324 (based on user usage).
Once 50%
of the expected lifetime of the pod 324 has expired, the controller 314 may signal an increase in the temperature by around 30%. The controller 314 may be fed back information on the temperature experienced by the pod 324 by the temperature sensor 316 and so modulate the temperature signals accordingly. This may enable (on a predetermined basis) the deeper flavour to be accessed, and so released into the aerosol, later in the lifetime of the pod 324.
In an example, the temperature signal from the controller 314 is sent to the aerosol generator 322 and the aerosol generator 322 increases the temperature of the heater used to generate the aerosol. If this aerosol does not efficiently carry thermal energy to the pod 324, the temperature sensor 316 may detect this and signal to the controller 314 accordingly. The
7 controller 314 may then provide a further instruction to increase the temperature of the heater used to generate the aerosol to the aerosol generator 322. This loop may continue until the desired temperature is achieved at the pod 324.
In an example, the sensing element 316 is a position sensor. The position sensor 316 may detect orientation and position (absolute and/or relative) data about the pod 324. This may be via an optical sensor (e.g. camera) or the like. The position sensor 316 may send signals to the controller 314 which in turn sends a signal to control a modulation in the relative positions of the pod 324 and the aerosol generator 322. By moving the aerosol generator 322 closer to the pod 324, the aerosol produced by the aerosol generator 322 will lose less thermal energy prior to reaching the pod 324. In this way, the pod 324 may be provided with greater thermal energy.
In the example of Figure 4, an aerosol provision system 400 is shown. The example of Figure 4 is similar to the examples of Figures 1, 2 and 3. Where similar components are shown in both Figures 3 and 4, the numerals on Figure 4 used to refer to the similar component from Figure 3 have been increased by 100 for simplicity. For efficiency, these components may not be discussed in detail again here.
The aerosol provision system 400 shown in Figure 4 has a mechanical element 418. The mechanical element 418 may be arranged to provide relative movement between the pod 424 and the aerosol generator 422. The mechanical element 418 may be arranged to provide relative movement between the pod 424 and the direction of flow of aerosol generated in use by the aerosol generator 422. By moving the pod 424 towards the aerosol generator 422 or towards the flow of aerosol flowing towards the pod 424, the pod 424 will experience a hotter aerosol, as the aerosol will have had less time to lose energy while approaching the pod 424.
This is as a direct result of reducing the distance over which the aerosol must travel to reach the pod 424.
The mechanical element 418 may provide relative movement such as any of linear movement, indexed movement or rotational movement. The mechanical element 418 may be or include any of a pusher system, a Geneva wheel or a spinning disk or the like. The mechanical element 418 may be mechanically linked to the aerosol generator 422 and/or the
8 pod 424. The mechanical element 418 may therefore alter the relative positions of the aerosol generator 422 and the pod 424.
In an example, the controller 414 receives an indication that the pod 424 has been inserted into region A. The controller 414 can therefore detect the usage on the pod 424 through the lifetime of the pod 424. Using predetermined measurements of number of puffs and intensity of puffs, the controller 414 may control the temperature in the region A to provide flavour accordingly (as the pod ages, higher temperatures are needed to access deeper flavour). Later in the lifetime of the pod 424, the controller 414 may receive readings from the sensing element 416 that the temperature is not sufficient to access the deeper flavour. The controller 414 then provides a signal to the aerosol generator 422 to provide aerosol at a higher temperature. The controller 414 may receive a signal from the sensing element 416 that this temperature increase is sufficient. Later in the lifetime of the pod 424, this aerosol temperature may no longer be sufficient. The controller 414 may opt to send another signal to the aerosol generator 422 to increase the temperature but the controller 414 may also or alternatively send a signal to the mechanical element 418 to move the pod 424 relative to the aerosol generator 422. This may advantageously remove or decrease the need for the aerosol generator 422 from operating at an overly high temperature. As such, in combination the controller 414, aerosol generator 422 and the mechanical element 418 provide a flexible system for controlling the temperature at the pod 424 while protecting the lifetime of components within the system 400. This comes from not over-working e.g. the aerosol generator 422.
The mechanical element 418 may rotate the pod 424 so as to change the portion of the pod 424 that faces the aerosol generator 422. The portion of the pod 424 which is facing the aerosol generator 422 will receive a greater proportion of the heat of the aerosol from the aerosol generator 422 than the portion of the pod facing away from the aerosol generator 422.
As such, the flavour in the pod 424 may be depleted more quickly on one side than another of the pod 424. To maintain an even level of depletion, the pod 424 may be rotated by the mechanical element 418. This prevents overheating of one side of the flavour;
overheating of a flavour may lead to undesirable compounds or aromas being produced.
In the example of Figure 5, an aerosol provision system 500 is shown. The example of Figure 5 is similar to the examples of Figures 1, 2, 3 and 4. Where similar components are
9 shown in both Figures 4 and 5, the numerals on Figure 5 used to refer to the similar component from Figure 4 have been increased by 100 for simplicity. For efficiency, these components may not be discussed in detail again here.
The aerosol provision system 500 has a heating element or heater 519 for providing heat to the pod 524. The heater 519 may be any of a resistive heater, inductive heater, chemical heater or the like. The controller 514 controls the heat delivery of the heater 519 to the pod 524. The heater 519 may provide additional heat directly to the pod 524 and so reduce the requirement of the thermal energy of the aerosol from the aerosol generator 522. The sensing element 516 may signal to the controller 514 that further heat is required and the controller 514 may activate the heater 519. This will reduce the electrical strain on the aerosol generator 522. Use of the heater 519 also allows heat to be provided more specifically and accurately to the pod 524.
In the example of Figure 6, an aerosol provision system 600 is shown. The example of Figure 6 is similar to the examples of Figures 1, 2, 3, 4 and 5. Where similar components are shown in both Figures 5 and 6, the numerals on Figure 6 used to refer to the similar component from Figure 5 have been increased by 100 for simplicity. For efficiency, these components may not be discussed in detail again here.
The aerosol provision system 600 has a heater movement mechanism 6191 arranged to provide relative movement of the heater 619 to the pod 624. The controller 614 is arranged to control the heater movement mechanism 6191. In an example, the controller 614 detects the aerosol provision device 610 and an aerosol generating component 620 are engaged. The controller 614 notes the usage of the system 600 and therefore the age of the pod 624. The controller 614 is informed of a temperature in the region A and, based on the age of the pod 624, signals for an increase in temperature of the region A. This may occur by increasing the temperature of the aerosol produced by the aerosol generator 622.
Alternatively or additionally, this may occur by moving the pod 624 (and therefore region A) towards the aerosol generator 622 or by activating (or increasing the temperature of) the heater 619.
When the controller 614 wishes for a further increase of temperature the controller 614 may move the heater 619 and pod 624 closer to one another through activation of the heater movement mechanism 6191. The heater movement mechanism 6191 may move the heater 619, the pod 624 or both. In this way, the controller 614 can precisely control the temperature provided to the pod 624.
The provision of these components provides the controller 614 with a great level of control over the temperature experienced by the pod 624. This allows precise temperatures to be provided such that the precise amount of flavour may be accessed at a precise lifetime of the pod 624. This increases the user experience of the system 600 and prevents the pod 624 from providing an undesired amount of flavour to the aerosol during use.
In an example, the pod 624 may contain multiple flavours which are released at different temperatures. The great level of control over the temperature experienced by the pod 624 allows the controller 614 to accurately deliver one flavour and not another according to user preference.
The heater movement mechanism 6191 may be arranged to move the heater 619 relative to the pod 624 so that the heater 619 directs heat towards different portions of the pod 624 over the lifetime of the pod 624. This assists in a more even depletion of the flavour within the pod 624. As explained above, this helps prevent overheating of one side of the flavour over another side. In combination with the other heating and movement elements, the controller 614 of the system 600 can provide a bespoke heating profile over the lifetime of the pod 624 so as to controllably release the flavour at different depths in the pod 624.
The sensing element 616 allows for checking of this heating profile and allows feedback on the profile allowing for amendment of the profile should it be needed.
In any of the above examples, the system may further have a puff detector to enable detection of system usage. This may he signalled to the controller which may retain usage statistics for use in calculating what temperature to provide to the pod.
In any of the above examples, the controller (which may be control circuitry) may be connected to a database for determining when certain predetermined values are exceeded or are outside of predetermined ranges (such as temperatures used in relation to the remaining lifetime of the pod). This may lead to an amendment of the temperature experienced by the pod by any of the above methods.

In some embodiments, the non-combustible aerosol provision system is an electronic cigarette, also known as a vaping device or electronic nicotine delivery system (END), although it is noted that the presence of nicotine in the aerosolisable material is not a requirement.
In some embodiments, the non-combustible aerosol provision system is a tobacco heating system, also known as a heat-not-burn system.
In some embodiments, the non-combustible aerosol provision system is a hybrid system to generate aerosol using a combination of aerosolisable materials, one or a plurality of which may be heated. Each of the aerosolisable materials may he, for example, in the form of a solid, liquid or gel and may or may not contain nicotine. In some embodiments, the hybrid system comprises a liquid or gel aerosolisable material and a solid aerosolisable material.
The solid aerosolisable material may comprise, for example, tobacco or a non-tobacco product.
Typically, the non-combustible aerosol provision system may comprise a non-combustible aerosol provision device and an article for use with the non-combustible aerosol provision device. However, it is envisaged that articles which themselves comprise a means for powering an aerosol generating component may themselves form the non-combustible aerosol provision system.
In some embodiments, the non-combustible aerosol provision device may comprise a power source and a controller. The power source may, for example, be an electric power source.
In some embodiments, the article for use with the non-combustible aerosol provision device may comprise an aerosolisable material, an aerosol generating component, an aerosol generating area, a mouthpiece, and/or an area for receiving aerosolisable material.
In some embodiments, the aerosol generating component is a heater capable of interacting with the aerosolisable material so as to release one or more volatiles from the aerosolisable material to form an aerosol.

In some embodiments, the substance to be delivered may be an aerosolisable material.
Aerosolisable material, which also may be referred to herein as aerosol generating material, is material that is capable of generating aerosol, for example when heated, irradiated or energized in any other way. Aerosolisable material may, for example, be in the form of a solid, liquid or gel which may or may not contain nicotine and/or flavourants.
In some embodiments, the aerosolisable material may comprise an -amorphous solid", which may alternatively be referred to as a "monolithic solid" (i.e. non-fibrous).
