AEROSOL-GENERATING SYSTEM

Description

TECHNICAL FIELD

The present invention relates to an aerosol-generating system, an aerosol provision device, a method of providing an aerosol for inhalation by a user, and aerosol-generating means.

BACKGROUND

Aerosol-generating 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 be activated by a user at the push of a button or merely by the act of inhalation. Modern systems can use consumable elements containing the aerosol generating material. It can be desirable for the manufacturer to enable control over the activation of the systems. This may avoid the activation of the system in undesirable circumstances.

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-generating system, for providing an aerosol for inhalation by a user, comprising: an aerosol provision device comprising control circuitry for controlling an activation state of the aerosol provision device; a detector arranged to detect a first property associated with aerosol generating material, in use arranged in the aerosol provision device, and provide a signal to the control circuitry; and, age verification means for verifying an age of a user, wherein the control circuitry is arranged to perform at least one of i) update an activation state of the aerosol provision device, and ii) activate the age verification means in response to receiving a signal from the detector.

Such a system is able to identify the aerosol generating material intended for use with the aerosol provision device, ascertaining if it is an age-restricted aerosol generating material and then updating an activation state of the aerosol provision device and/or activate an age verification means. This allows the system to determine if age verification is required (as a result of the aerosol generating material intended for use) and then perform age verification if it is. This provides an increased in-use safety aspect for the system while avoiding unnecessary interference in circumstances that do not require age verification. This therefore strikes a balance between overly strict and overly lenient control over the usage of the aerosol provision device.

In particular, in the event that consumable 1 is supplied for use with the aerosol provision device, consumable 1 containing an age-restricted aerosol generating material, age verification can be requested prior to operation of the device. In contrast, when consumable 2 is supplied for use with the aerosol provision device, consumable 2 not containing an age-restricted aerosol generating material, the device is allowed to operate without age verification. In this way, the manufacturer can provide a device that has a broad utility across a number of consumables and users, while protecting the device from being used with aerosol generating material that is unsuitable for a specific user.

The user experience of the device may also be increased by having a personalisable, “plug-and-play” approach. In that, the user may be provided with a number of options from which to select the operating state that the user desires. In this way, the user need not create, from scratch, an operating state for use with a consumable (containing a specific aerosol generating material), but can refine their preference from a number provided. In this way, the safety of the device is also maintained as each of the possible selectable operating states are known by the manufacturer to provide a suitable aerosol without damaging the device. Therefore, both the device and user benefit from the arrangement. Furthermore, the user may only be able to access some of the operating states following age verification-increasing the overall safety of use of the device.

By requiring detection of a first property associated with aerosol generating material in-use combined with the aerosol provision device for providing an aerosol for inhalation by a user, the system may hinder use of non-authentic consumables. In particular, if the identification method is not compatible with the aerosol generating material (by virtue of it being non-authentic) the device may not be able to operate. In this way, the device can be protected from use with unknown and un-tested consumables (containing unknown and/or un-tested aerosol generating material) that might provide a substandard aerosol for the user or damage the device in an attempt to produce an aerosol.

The aerosol provision system of the present invention is able to operate in “offline” or “online” mode when performing age verification of potential users. In this way, a valid user may operate the system in offline (unconnected to a mobile network or internet or the like) environment provided the user satisfies the criteria for operation. The user experience of the device is thereby improved. This can be achieved by including a memory in the aerosol provision system with which the age verification means communicates.

In accordance with some embodiments described herein, there is provided 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 a first property associated with aerosol generating material, in use arranged in the aerosol provision device, and provide a signal to the control circuitry; and, age verification means for verifying an age of a user, wherein the control circuitry is arranged to perform at least one of i) update an activation state of the aerosol provision device, and ii) activate the age verification means in response to receiving a signal from the detector.

In accordance with some embodiments described herein, there is provided a method of providing an aerosol for inhalation by a user, the method comprising: detecting, by a detector, a first property associated with aerosol generating material arranged in an aerosol provision device; providing, by the detector, a signal to control circuitry of the aerosol provision device; in response to receiving, at the control circuitry, a signal from the detector, performing at least one of: updating, by the control circuitry, an activation state of the aerosol provision device; and activating, by the control circuitry, age verification means.

In accordance with some embodiments described herein, there is provided aerosol-generating means, for providing an aerosol for inhalation by a user, comprising: an aerosol provision device comprising control means for controlling an activation state of the aerosol provision device; detecting means arranged to detect a first property associated with aerosol generating material, in use arranged in the aerosol provision device, and provide a signal to the control means; and, age verification means for verifying an age of a user, wherein the control means is arranged to perform at least one of i) update an activation state of the aerosol provision device, and ii) activate the age verification means in response to receiving a signal from the detecting means.

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.

FIG. 1 illustrates a schematic view of an example of an aerosol provision system 100 according to the present invention. The aerosol provision system 100 comprises an aerosol provision device 110. The aerosol provision device 110 has control circuitry 120. The control circuitry 120 is arranged to control an activation state of the aerosol provision device 110. The aerosol provision system 100 comprises a detector 130 arranged to detect a first property associated with aerosol generating material, in-use arranged in the aerosol provision device 110 and provide a signal to the control circuitry 120. The aerosol provision system 100 further comprises age verification means 140 for verifying an age of a user. The control circuitry 120 is arranged to perform at least one of update an activation state of the aerosol provision device 110 and activate the age verification means 140.

In an example, the detector 130 detects a property of the aerosol generating material 132 to ascertain whether age verification is required prior to use of the aerosol generating material 132 in the aerosol provision device 110. The property of the aerosol generating material 132 that may impact the requirement of age verification may be any of a chemical composition of the aerosol generating material, a strength of the aerosol generating material, a size of the consumable, a rating of the consumable, an authenticity of the consumable; amount; date of production; and, batch number or the like.

The detector 130 detects the property and provides a signal to the control circuitry 120. The control circuitry 120 may process the signal and assess whether age verification is required. If age verification is required, the control circuitry 120 activates the age verification means 140. The user is then informed that to activate the device 110, age verification must be satisfied. Following age verification, the control circuitry 120 can assess whether the user is a valid user for use with the identified aerosol generating material 132 or not. If the user is valid, the device 110 is allowed to activate to provide an aerosol for inhalation to the valid user. If the user is not valid, the control circuitry 120 prevents activation of the device 110.

In this way, age verification is only provided when required. In this way a balance is struck between impacting the user experience for safety and the safety of use of the device.

The full range of operating states of the aerosol provision system 100 may be very wide ranging such that the aerosol provision device 110 can be used with a correspondingly wide range of aerosol generating materials 132. In this way, the user need not be limited to only certain types of aerosol generating material 132 for use with the aerosol provision device 110. However, from within this wide range, some operating states will not be suitable for use with some aerosol generating materials 132. As such, it is important to offer states that will provide a desirable aerosol from the aerosol generating material 132. By offering all the possible states to all consumables, the onus would be put onto the user to work out which operating states interact well with which consumables. This may decrease the user experience of the system 100.

The aerosol provision device 110 may comprise heating arrangements or the like for providing an aerosol from a consumable—the consumable may contain some aerosol generating material or the like. The control circuitry 120 may control the heating arrangement (or the like) according to the signal received from the detector 130. The detector 130 enables the control circuitry 120 to ascertain what heating process is suitable for use with the identified aerosol generating material 132. Once age verification is satisfied or deemed unnecessary, the device 110 may offer the user one of a number of heating processes for use with the aerosol generating material 132 to improve user experience. This may be part of the updating of the activation state of the aerosol provision device 110.

In a specific example, the control circuitry 120 is arranged to update an activation state of the aerosol provision device 110 to a non-operating state in response to receipt of a signal from the detector 130 associated with the first property having or exceeding a predetermined value. For example, where the aerosol generating material 132 contains a nicotine value above negligible or zero, the system 100 is prevented from providing an aerosol to the user until age verification is satisfied. In this way, the user is protected from use of unsuitable aerosol generating material. The user may interact with the age verification means 140 to provide an age, where the device 110 may be allowed then to provide an aerosol.

In the above specific example, the control circuitry 120 is arranged to activate the age verification means 140 in response to receipt of a signal from the detector 130 associated with the first property (e.g. nicotine content) having or exceeding a predetermined value.

In a specific example, the control circuitry 120 is arranged to update an activation state of the aerosol provision device 110 to an operating state in response to receipt of a signal from the detector 130 associated with the first property being less than a predetermined value. For example, where the aerosol generating material 132 contains a nicotine value that is negligible or zero, the system 100 is allowed to provide an aerosol to the user without satisfying age verification. This may also be applied to other suitable age-restricted compounds.

The age verification means 140 may comprise at least one of: a face scanner; a fingerprint scanner; an iris scanner; a microphone; a camera; a mobile device; and, a communication module for communicating with a database.

In the example of a camera, the age verification means 140 may factor in aspects such as lines in the face, bags under the eyes, and prevalence of e.g. in males, facial hair to provide an age verification means. Such factors can be used to indicate a probable age range of the potential user of the device 110. The age verification means 140 may perform an analysis of the data taken of the user, and provide a signal to the control circuitry 120 indicating whether the user is of a likely suitable or likely unsuitable age for use of the device. Alternatively or additionally, the camera may be used to inspect a users identification, such as a passport to the like, to detect an age of the user. If there is an image on the identification, this can be compared against the user's face using the camera.

In the example of FIG. 1, the age verification means 140 is not integral with the aerosol provision device 110. In the example of FIG. 1, the detector 130 is not integral with the aerosol provision device 110.

Referring now to FIG. 2, there is a shown a similar system 200 to the system 100 of FIG. 1. Similar features, to those features used in FIG. 1, are shown with the reference numerals increased by 100. For example, the system 100 of FIG. 1 is similar to the system 200 of FIG. 2. Similar or identical features may not be discussed for conciseness.

The system 200 of FIG. 2 has aerosol provision device 210 comprising the control circuitry 220, detector 230, and aerosol generating material 232. The age verification means 240 is located outside of the aerosol provision device 210.

In the example shown in FIG. 2, the aerosol generating material 232 is shown in-use as located inside the aerosol provision device 210 forming a portion of the aerosol provision system 200. In this example, the aerosol generating material 232 may be inserted into the housing of the aerosol provision device 210. In this way, when located inside the aerosol provision device 210, the aerosol provision device 210 may identify, via detector 230, the aerosol generating material 232. The aerosol generating material 232 may be in the form of a pod or a cartridge containing aerosol generating material which is inserted into the aerosol provision device 210 and then discarded or refilled after use.

The age verification means 240 may be separate to the aerosol provision device 210 and used separately, while communicatively coupled to the control circuitry 220. The control circuitry 220 may provide a notification to alert the user that age verification is required and to conduct such through the age verification means 240. The age verification means 240 may be a mobile phone or the like.

The age verification means 240 receives a signal from the control circuitry 220 corresponding to a request to operate and perform age verification on the user. The age verification means 240 may detect a property associated with a potential user and provide age verification. The age verification means 240 then provides a signal back to the control circuitry 220 corresponding to whether or not the potential user has satisfied age verification. Where the user satisfies age verification, the control circuitry 220 provides a signal to heaters or the like to function and provide an aerosol from the aerosol generating material 232 in the aerosol provision device 210.

In the event that the age verification means 240 detects the user is in an age range (or of an age) suitable for using the system 200 in all operational modes (such as heating age restricted aerosol generating material), the control circuitry 220 may allow any such activation of the device 210. In the event that the age verification means 240 detects the user is not in an age range (or of an age) suitable for use with the aerosol generating material 232 the control circuitry 220 may signal to the user that the aerosol generating material 232 is to be removed from the aerosol provision device 210. Notifications to the user may occur via a screen on the aerosol provision device 210 or any other suitable means such as a display on the age verification means 240.

This arrangement allows suitable handling of a device that is used by multiple users of different age. The users of suitable age are allowed to access suitable operational states for respective aerosol generating materials, while users of un-suitable age are prevented from doing so. This ensures that suitability of use is prioritised alongside user safety.

In an example, the control circuitry 220 is arranged to update an activation state of the aerosol provision device 210 in response to receipt of an access signal or deny signal from the age verification means 240. In response to receipt of an access signal, the control circuitry 220 may update the device 210 to a full access mode where all functions are allowed for the aerosol generating material 232. In response to receipt of a deny signal, the control circuitry 220 may update the device 210 to a no access mode, where all functions are denied or only partial functionality is provided for the aerosol generating material 232.

In an example, the control circuitry 220 is arranged to provide a notification to a user in response to receipt of a deny signal from the age verification means 240. The notification may be in the form of an audible signal, a visual signal, a haptic signal, a textual message or the like displayed on a screen or display or the like. Any suitable notification method may be used, including sending a signal to a personal device of the user, such as a smart device or the like. The age verification means 240 may be a smart device. The notification may be provided from the age verification means 240.

Referring now to FIG. 3, there is a shown a similar system 300 to the system 200 of FIG. 2. Similar features, to those features used in FIG. 2, are shown with the reference numerals increased by 100. For example, the system 200 of FIG. 2 is similar to the system 300 of FIG. 3. Similar or identical features may not be discussed for conciseness.

The device 310 of FIG. 3 is shown containing the control circuitry 320, detector 330, aerosol generating material 332 and an age verification means 340. The system 300 is therefore more compact than the system 200 of FIG. 2. There is no need for a separate age verification means in the arrangement of FIG. 3. This may improve the user experience as the user need not carry multiple items for accessing the device 310.

Referring now to FIG. 4, there is a shown a similar system 400 to the system 300 of FIG. 3. Similar features, to those features used in FIG. 3, are shown with the reference numerals increased by 100. For example, the system 300 of FIG. 3 is similar to the system 400 of FIG. 4. Similar or identical features may not be discussed for conciseness.

The device 410 of FIG. 4 is shown containing the control circuitry 420, detector 430, aerosol generating material 432 and an age verification means 440. The age verification means 440 comprises an additional element 442. The element 442 may be a communication element to allow the age verification means 440 to communicate with a remote database. The element 442 may be a memory storing an on board database. The element 442 may be both a communication element and a memory.

In the above example, the age verification means 440 receives signals from the control circuitry 420 and provides a notification to the user to perform age verification. The age verification means obtains a signal from the user and provides to the element 442.

The element 442 may be a database stored in a memory on board the device 400. The signal from the from age verification means 440 is compared to the on board database. If the signal is associated with a user of suitable age, the device 410 is updated into an operational state. This on board database arrangement may be advantageous as the device 400 need not have a communications element in the device 400 to communicate with a remotely held database, and the device 400 need not be connected to a communications network to access a remotely held database prior to each use session. This may allow use of the device 410 in areas without connectivity. This may also provide a faster response than via communicating with a remote database.

In a different example, the database of user age is held remotely, and the age verification means 440 has a communication module 442 to contact the database. The communication module 442 may contact the database with a request for confirming user age. The communication module 442, and therefore the age estimation module 440, is then provided with an age of the potential user, which is relayed to the control circuitry 420. This arrangement may be advantageous as the device 410 need not include a memory element for carrying the database and the database can be remotely updated ensuring the device 410 need not have the on board database regularly updated. In this way up-to-date age data can be provided to all devices 410 as soon as the data is uploaded to the central database. In this way, all users can be provided with the updates without each needing to update their own device 410. The remote database may be a governmental database or the like for linking a property of a user to a known age for that user, or for verifying the identification of a user where the identification contains an indication of age for that user.

The present invention involves changing an activation sate of the aerosol provision device. In an “operating state”, elements of the aerosol provision device 410 used to generate an aerosol (such as an atomiser, heater or the like) may be activated. The specific activation of the device 410 may require an additional input which may be inhalation on the device 410, pressing a button on the device 410 or the like. Alternatively, the device 410 may automatically generate aerosol by a heater in response to receiving a signal associated with a valid potential user. The control circuitry 420 may receive such a signal from the age verification means 440 and send a signal to the heater arrangement or the like to provide an aerosol from an aerosol generating material 432 that may contained within, or separate to, the aerosol provision device 410.

FIG. 5 shows a method 500 of use of an aerosol provision device. In the method 500, the device may start in a default state 502, which may be a non-operating state such that when age restricted aerosol generating material is provided to the device, users cannot use the device without age verification or the detection of no age-restricted aerosol generating material being present. Alternatively, the default operating state may be a restricted operating state where only partial operation of the device is possible. Alternatively, the device may be an operating mode and is prevented from operating in response to detection of age-restricted aerosol generating material.

When a user intends to use the aerosol provision device, the user inputs the aerosol generating material to the device. The device detects a first property of the aerosol generating material 404. The device detects the first property using a detector (which may contain a number of individual sensors/detectors). The detector may detect the property from a barcode, QR code, label or the like, or may detect the chemical composition of the aerosol generating material directly.

The detector sends a signal accordingly to the control circuitry 506. An assessment is made whether age verification is required or not—this may occur at the detector or the control circuitry. If age verification is not required, the activation state of the aerosol provision device may be updated 508, if it is, the age verification means may be activated 508.

This method provides a user-friendly age verification process that does not impede overly use for non age-restricted aerosol generating materials. The method offers a balance between overly strict and overly lenient access protection for the device and aerosol generating material.

The updating of the activation state may involve updating, by the control circuitry, an activation state of the aerosol provision device to an operating state in response to receiving a signal from the detector associated with the first property being less than a predetermined value. The updating of the activation state may involve updating, by the control circuitry, an activation state of the aerosol provision device to a non-operating state in response to receiving a signal from the detector associated with the first property having or exceeding a predetermined value.

The term “in response to” is used herein to indicate a second event (such as a signal or change of state of an aerosol provision device) that occurs subsequent to a first event. The second event may occur at a later time, after a predetermined time, or immediately after the first event.

The device and system herein are described as comprising several components that enable several advantages. The components may be disclosed as on-board the device or within the system. The components may be distributed and therefore not necessarily be located on-board the device. The functionality of the device can be provided by communicatively connected components, and such communication may be wireless, enabling such distribution. At which point it is reasonable to foresee that a distributed array of components will operate in the manner of the devices and systems disclosed herein. Components of the device or system may be contained in a further device such as a smartphone, computer, or remote server or the like.

The method and device disclosed herein enable protection over the use of the device without requiring an arduous authorisation process—the process is only as arduous as is required considering the content of the aerosol generating material to be used. This improves the user experience of the device and the safety of general use of the device.

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, cognac, jasmine, 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.
