The present specification relates to a non-combustible aerosol-generating device, to an non combustible aerosol-generating system, and to a method of controlling a non-combustible aerosol-generating device.
Smoking articles, such as cigarettes, cigars and the like burn tobacco during use to create tobacco smoke. Attempts have been made to provide alternative delivery devices to these articles by creating products that release compounds without combustion. Examples of such delivery devices are so-called “heat not burn” products or tobacco heating devices or products, which release compounds by heating, but not burning, a substrate. For example, tobacco heating devices heat an aerosol generating substrate, which may be tobacco or other non-tobacco products which may or may not contain nicotine, to form an aerosol by heating the substrate without burning it.
In accordance with some embodiments described herein, there is provided a non-combustible aerosol-generating device, comprising a display for displaying an image visible to a user in an activated state, and control circuitry configured to detect the presence of a user and/or a remote device in the proximity of the aerosol-generating device, and to switch the display from a deactivated state in which no image is displayed to an activated state in response to said detection.
The control circuitry may be configured to control the display so that it switches from an activated to a deactivated state after the control circuitry fails to detect the presence of a user and/or a remote device in the proximity of the aerosol-generating system after a predetermined period of time.
The control circuitry may comprise a sensor to detect the presence of a user and/or a remote device proximal to the aerosol-generating device, and a display driver configured to receive a signal from the sensor indicative of said detected presence. The display driver may then control the display to switch from a deactivated to an activated state.
In certain embodiments, the sensor is configured to detect the presence of a user and/or a remote device when the user and/or the remote device is spaced from said aersol-generating device, and such that the display driver switches the display to an activated state without the aerosol-generating device being touched.
The sensor may be a communication interface configured to receive a signal from a remote device spaced from, but proximal to, the aerosol-generating device. The signal may be a wireless signal, such as wireless signal using the Bluetooth protocol.
The remote device may comprise a smart phone, tablet, smart watch or another non-combustible aerosol-generating device.
The sensor 16 can be a capacitive proximity sensor. Whatever type of sensor is used, it can take the form of an array of proximity sensing elements.

In the embodiment which changes or modifies a displayed image, the control circuitry may comprise a sensor to detect the presence of a user and/or a remote device spaced from, but proximal to, the aerosol-generating device. The control circuitry may also comprise a display driver configured to receive a signal from the sensor indicative of the presence of a user and/or a remote device, and to change or modify a displayed image in response to the detection.
The sensor may be a communication interface that is configured to receive a signal from a remote device spaced from, but proximal to, the aerosol-generating device. The signal may be a wireless signal, and can be a wireless signal that uses the Bluetooth protocol.
The remote device may comprise a smart phone, tablet, other smart wearable technology such as a smart watch, or another non-combustible aerosol-generating device.
In certain embodiments, the sensor may be a capacitive proximity sensor, and can include an array of proximity sensing elements.
In any embodiment of the invention, the non-combustible aerosol-generating device according to the invention may comprise a housing having an outer surface, and the display can be attached to the outer surface of the housing.
The outer surface of the housing may comprise a contoured shape, and the display may be configured so that it conforms to the contoured shape of the outer surface of the housing.
The housing can be generally tubular and the outer surface may extend about a longitudinal axis. The display may then extend about the longitudinal axis for at least 90 degrees, at least 180 degrees or 360 degrees, or for any other angle.

In accordance with another embodiment of the invention, there is also provided a method of controlling a non-combustible aerosol-generating device, comprising detecting the presence of a user and/or a remote device spaced from but proximal to the aerosol-generating device, and changing or modifying a displayed image in response to said detection.
Embodiments of the invention will now be described, by way of example only, with reference to the accompanying drawings, in which:
According to the present disclosure, a “non-combustible” aerosol provision system is one where a constituent aerosol-generating material of the aerosol provision system (or component thereof) is not combusted or burned in order to facilitate delivery of at least one substance to a user.
In some embodiments, the non-combustible aerosol provision system is an electronic cigarette, also known as a vaping system or electronic nicotine delivery system (END), although it is noted that the presence of nicotine in the aerosol-generating material is not a requirement.
In some embodiments, the non-combustible aerosol provision system is an aerosol-generating material heating system, also known as a heat-not-burn system. An example of such a system is a tobacco heating system.
In some embodiments, the non-combustible aerosol provision system is a hybrid system to generate aerosol using a combination of aerosol-generating materials, one or a plurality of which may be heated. Each of the aerosol-generating materials may be, 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 aerosol-generating material and a solid aerosol-generating material. The solid aerosol-generating 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 a consumable, such as an article, for use with the non-combustible aerosol provision device. An aerosol-generating material is a material that is capable of generating aerosol, for example when heated, irradiated or energized in any other way. An aerosol-generating material may be in the form of a solid, liquid or gel which may or may not contain an active substance and/or flavourants.
In some embodiments, the non-combustible aerosol provision device may comprise an area for receiving the consumable, an aerosol generator, an aerosol generation area, a housing, a mouthpiece, a filter and/or an aerosol-modifying agent.
In some embodiments, the consumable for use with the non-combustible aerosol provision device may comprise aerosol-generating material, an aerosol-generating material storage area, an aerosol-generating material transfer component, an aerosol generator, an aerosol generation area, a housing, a wrapper, a filter, a mouthpiece, and/or an aerosol-modifying agent.
Referring to
The device 1 comprises an electronics/power chamber 6 containing electrical control circuitry 7 and a power source 8. In this example, the heating chamber 4 and the electronics/power chamber 6 are adjacent to each other along the longitudinal axis X-X of the device 1. The electrical control circuitry 7 may include a controller, such as a microprocessor arrangement, configured and arranged to control the heating of the smokable material 5, and incorporates a display driver 15 for controlling images appearing on a display or displays that form part of the device 1, as will be described in more detail below.
The electrical control circuitry 7 may in use receive a signal from, for example, a puff-actuated sensor (not shown) which is sensitive to for example changes in pressure or changes in rate of air flow that occur upon initiation of a draw on the smokable material article 5 by a user. The electrical control circuitry 7 can then operate so as to cause heating of the smokable material article 5 “on demand” when required. Various arrangements for a puff-actuated sensor are available, including for example a thermistor, an electro-mechanical device, a mechanical device, an optical device, an opto-mechanical device and a micro electro mechanical systems (MEMS) based sensor. As an alternative, the device 1 may have a manually operable switch for a user to initiate a puff.
The power source 8 may be a battery, which may be a rechargeable battery or a non-rechargeable battery. Examples of suitable batteries include for example a lithium-ion battery, a nickel battery (such as a nickel-cadmium battery), an alkaline battery and/or the like. The battery 8 is electrically coupled to the one or more heating elements 10 of the heating chamber 4 to supply electrical power when required and under control of the electrical control circuitry 7 to heat and volatize the smokable material 5 without causing it to burn. In this example, the battery 8 is contained within a printed circuit board of the electrical control circuitry 7. In other examples, the battery 8 and the electrical control circuitry 7 may be arranged differently, such as for example arranged adjacent each other along the longitudinal axis X-X of the apparatus 1.
The heating chamber 4 is contained within a heater support sleeve 9, which is contained within the outer housing 2. In this example, the heater support sleeve 9 is a generally elongate cylinder of circular cross-section. In an example, the heater support sleeve 9 is a double-walled or “vacuum” sleeve, having an outer cylindrical wall and an inner cylindrical wall which are joined to each other at each end.
In one example of the device 1, the heater support sleeve 9 contains plural heating elements or heater segments 10. In this example, the heater segments 10 align along or parallel to the longitudinal axis X-X of the heater support sleeve 9. The electrical control circuitry 7 is configured to supply power to the heater segments 10 to heat the smokable material article 5.
The device 1 in accordance with an embodiment of the present invention shown in
Whilst the display 12 is shown proud of the housing 2 in the
As shown in
The display 12 may extend about the longitudinal axis of the housing 2 for any angle. However, the display 12 preferably extends about the housing 2 for at least 90 degrees, at least 180 degrees or 360 degrees, as shown in
In certain circumstances, the display 12 may be resiliently flexible such that a mechanical or pressure sensitive button, i.e. an on/off button, located beneath the display 12 may be activated by applying pressure to the display 12 to temporarily deform the display 12 and, in turn, apply pressure to the button to activate it.
Graphics or other images or indicia may appear on the display 12 to indicate to the user the location and/or status of the button located beneath the display 12. The graphics or images may change once the button has been activated. The display 12 may be a flexible display 12 to facilitate formation of the curved viewing surface. In particular, the flexible display 12 may be flexed to provide the curved viewing surface. Once the display 12 is fixed or otherwise coupled to the housing 2, the display 12 may no longer be capable of flexing, for example, when the display 12 is at least partially or entirely attached to the housing 2.
In another embodiment, the display 12 forms an integral part of the housing 2, i.e. the display 12 and the housing 2 are a single integrated component such that the display 12 carries out the dual function of displaying images as well as defining the structural housing containing the components of the device 1, and so the display 12 itself forms the outer surface of the device 1.
The display 12 may be powered by the device battery 8. Alternatively, the display 12 may have its own, separate, power source such as another rechargeable battery (not shown) which is received within the housing 2. The device battery 8 and the display battery may be rechargeable together or independently from each other. The display 12 may be kept ‘on’ by default, only switching off or entering a ‘standby mode’ when, for example, power becomes low, or the system 1 hasn't been used for a period of time, particularly if a display 12 requiring minimum power is used, such as a e-ink type display.
In some embodiments, there can be more than one display 12, located elsewhere on the device, i.e. there may be two side-by-side displays 12. If a second, or further, display is provided, it may have the same or a similar construction to the first display 12. The images 12a displayed on the or each of the first and second displays 12 may be controlled via the display driver 15 of the control circuitry 7 so that there is some association between the displayed images, i.e. a moving image may initiate on one of the displays 12 to complement a different moving image on another display 12, to provide an appealing and interesting overall appearance. Alternatively, one of the displays 12 may be used primarily to provide the user with feedback or information relating to the status of the device 1, whereas another display 12 may be used to show a graphic or an image.
The display 12 may extend or wrap about the longitudinal axis (X-X) for at least 90 degrees, at least 180 degrees, 360 degrees or any other angle, to provide a curved and/or contoured viewing surface. Each of the second displays 12 may extend longitudinally (X-X) for at least part of the length of the housing 2.
The display driver 15 of the control circuitry 7 may be configured to control the display 12 to display predetermined images on the display 12 or on each display 12 if there is more than one.
The control circuitry 7 may comprise a memory 17 to store predetermined images to be displayed on the, or each, display 12 and the controller may be configured to access the memory in order to retrieve and display the predetermined images.
It will be understood that the images displayed by the or each display display 12 may include, comprise or consist of at least one of a solid colour, a pattern, an animation, a graphical representation or any text or other indicia.
In certain embodiments, the control circuitry 7 may be configured to control the displays so that one of the displays 12 displays static images, whilst another displays a moving image. Any suitable static image may be an image displayable on the display 12. The static image may include a cartoon-like image or a realistic image. The static image may be displayed in colour on part of all the display 12.
Any suitable motion image may be an image displayable on the display(s) 12. A motion image may appear as continuous movement or changes in the display 12. For example, brightness or the colour of various pixels may change. The motion image may include a cartoon-like image, a live action image, or a life-like action image (for example, using computer generated graphics).
If more than one display 12 is provided, they can be of the same type. However, each of the displays, or some of the displays 12 may be of a different type. For example, at least one of the displays can be an OLED, flexy TFT, display, OLCD, e-ink (or EPD), an AMOLED (active-matrix organic light-emitting diode display), or a PMOLED display. The type of display 12 will depend on the nature of the images to be displayed.
The display or displays 12 may include a plurality of pixels, for example, arranged into an array that are capable of forming images. The display(s) 12 may be used to show various images at different times. The images may be static images or motions images, which may be a series of static images or an encoded motion image. The display(s) 12 may show one or more viewable elements, selectable elements, and colours. The display 12 may be a colour display.
The control circuit 7 of the aerosol-generating device 1 includes a display driver 15, a communication interface, a controller (for example, a microprocessor or microcontroller), and a memory 17 to store data and images to be displayed by the, or each, display 12. The control circuitry 7 may be operatively coupled to one or more of the displays 12, to facilitate various functionality of the aerosol-generating device 1.
One or more of the controllers of the control circuitry 7 described herein may include a processor, such as a central processing unit (CPU), computer, logic array, or other device capable of directing data coming into or out of the aerosol-generating device 1. The controller includes one or more computing devices having memory, processing, and communication hardware. The functions of the controller may be performed by hardware and/or as computer instructions on a non-transient computer readable storage medium.
The processor of the controller may include any one or more of a microprocessor, a controller, a microcontroller, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA), and/or equivalent discrete or integrated logic circuitry. In some examples, the processor may include multiple components, such as any combination of one or more microprocessors, one or more controllers, one or more DSPs, one or more ASICs, and/or one or more FPGAs, as well as other discrete or integrated logic circuitry.
The functions attributed to the controller or processor herein may be embodied as software, firmware, hardware, or any combination thereof. While described herein as a processor-based system, an alternative controller could utilize other components such as relays and timers to achieve the desired results, either alone or in combination with a microprocessor-based system.
The exemplary systems, methods, and interfaces may be implemented using one or more computer programs using a computing apparatus, which may include one or more processors and/or memory 17. Program code and/or logic described herein may be applied to input data/information to perform functionality described herein and generate desired output data/information on the, or each, display 12. It will be readily apparent that the controller functionality as described herein may be implemented in any manner known to one skilled in the art.
The control circuitry 7 may be used to enable various modes of the aerosol-generating device 1. One example includes a visual artistic effect on activation mode, in which a motion image may be shown on the display or displays 12, in response to activation of the device 1, for example, by the actuator or puff senor. Upon detecting a puff and optionally receiving a puff profile, the controller may collect a memory address associated with the visual artistic effect to be shown on the, or each, of the displays 12. Data associated with the visual artistic effect may be fetched from the memory at the memory address. The data may be used to display or show the visual artistic effect on the, or each, display 12.
In certain embodiments of the non-combustible aerosol provision device 1, the control circuitry 7 is configured to detect the presence of a user and/or a remote device 20 (see
It will be understood that the expression “activated state” is intended to refer to a display 12 which is actively displaying an image. A display 12 which is said to be in an “inactivated state” is one which is not displaying an image, and so can be said to be switched off. A “switched off” display 12 or one which is in a “deactivated state” can also be said to be in what is commonly referred to as “sleep mode” or “standby”, in which the device 1 assumes a low power mode but no images are being displayed.
It will be appreciated that, whilst reference is made to a “user”, this term encompasses persons who intend to use the device 1, but also those in the proximity of the device 1, but who may not actually use the device 1.
If the non-combustible aerosol-generating device 1 is left unattended for a predetermined period of time, as determined by the control circuitry 7, the display 12 can be control so that it switches from an activated to a deactivated state in order to reduce electrical consumption of the battery 8.
The sensor 16 is capable of detecting the presence of a user and/or a remote device 20 proximal to the aerosol-generating device 1, and can supply a signal to the display driver 15 indicative of a detected presence. The display 12 may then be controlled so that it switches to an activated state from a deactivated state so that one or more images are displayed without the device 1, or the display 12, being physically touched.
If the display 12 is switched to its activated state without being touched, the sensor 16 can be a communication interface that is capable of receiving a signal, such as a wireless signal, from a remote device 20 spaced from, but proximate to, the aerosol-generating device 1. A suitable wireless signal may be one that is generated using a Bluetooth® protocol, infrared, near-field communication, or other wireless standard. Alternatively, a type of biometric authentication may be employed, such as a facial recognition system. Such a device 1 has the benefit of switching the display 12 to an activated state only in response to the presence of an authorised user, or switching the display 12 to an activated state so as to display a predetermined or particular image based on an identified user.
It will be appreciated that the remote device 20 can be any type of electrical device and can include a smart phone, a tablet, a smart watch or other wearable device, or even another non-combustible aerosol-generating device 1. An application may be installed on the remote device 20, such as on a smartphone or tablet, and this can receive user input to allow a user to decide what image is to be shown on the display 12 of the system 1 when it switches to an activated state.
In alternative embodiments, the sensor 16 may be a capacitive proximity sensor 16. In any embodiment, the sensor 16 may comprise an array of proximity sensing elements. The array of sensing elements may extend across the surface of the system, so that the display 12 will be triggered irrespective of the orientation of the system 1, or the location of the user or remote device 20.
In certain embodiments, the display 12 may switch from a deactivated to an activated state in response to being touched, in which case the display 12 can be a touch-sensitive display 12, i.e. a touchscreen, and the sensor 16 can be configured to detect the presence of a user, and to send a signal to the display driver 15, in response to the display 12 being touched.
A touch sensitive display 12 can be enabled as a capacitive touch sensitive display, a resistive or a force sensing display.
The steps involved in a method of controlling a non-combustible aerosol-generating device 1 according to the above-described embodiment of the invention, are shown in
In accordance with certain other embodiments, the control circuitry 7 can be configured to detect the presence of a user and/or a remote device 20 spaced from, but proximal to, the aerosol-generating device 1, and to change or modify a displayed image if the presence of a user and/or a remote device 20 proximate to the device 1 is detected.
In this embodiment, the display driver 15 may be configured to receive a signal from the sensor 16 indicative of the presence of a user and/or a remote device, and to change an existing image for another one, or to modify a displayed image by, for example, changing its position, orientation or appearance, which can include its colour or shading, or by combining an image with another image.
If the sensor 16 is capable of detecting a remote device 20, such as a smart phone, a tablet or another non-combustible aerosol-generating system, then the sensor 16 can be a communication interface which is configured to receive a signal from a remote device 20 which is located spaced from, but proximate to, the aerosol-generating device 1. As in previous embodiments, the communication interface may be configured to receive a wireless signal, such as a Bluetooth® signal, an infrared signal, or follow the near-field communication protocol, or other wireless standard. A form of biometric authentication, such as a facial recognition system, may also be employed so that images are changed or modified in a different way based on the presence of an identified user.
In an alternate embodiment, the sensor 16 is a capacitive proximity sensor 16, or an array of capacitive proximity sensors 16, or an array of another type of sensor 16, including an audio sensor 16 that detects noise in the vicinity of the device 1.
It will be understood that, in accordance with any embodiments of the invention, detection of a user or another device 1 may not only switch the display 12 to an activated state, or change or modify an image being displayed, but may also activate or switch on the device 1, so that the steps required to enable the device 1 to be used are initiated. In addition, or alternatively, detection of a user or another device may unlock the device 1 to enable it to be used.
The steps involved in a method of controlling a non-combustible aerosol-generating device 1 according to the aforementioned embodiment of the invention are illustrated in
It should be appreciated that while the above has focused, in part, on an aerosol-generating devices 1 of the “heat-not-burn” type, the principles described herein are not limited to aerosol-generating devices 1 of this type. For instance, one or more displays 12 may be provided on an aerosol-generating device configured to vaporise a liquid source (which may be achieved by vaporising a small amount of liquid extracted from a liquid reservoir containing a bulk liquid using a liquid transport element or wick). Such aerosol-generating devices are typically referred to as a vaping system or electronic nicotine delivery system (END). Such a system is formed of a device part and a cartridge (which is an example of a consumable part).
The cartridge part comprises a housing (e.g., formed of a plastic material), an aerosol-generating material storage area (or liquid reservoir), an aerosol-generating material transfer component (or wicking element, formed for example of a porous ceramic or bundle of fibres, such as cotton) arranged in fluid communication with the aerosol-generating material storage area, an aerosol generator (which may, for example, include a heating element, such as a resistance heating wire wrapped around the wicking element). The aerosol-generating material transfer component is arranged to provide aerosol-generating material (liquid) to the aerosol generator from the aerosol-generating material storage area. An air/aerosol pathway spans from an inlet of the cartridge to an outlet (which may correspond with a mouthpiece part of the cartridge, which in use, is intended to be inserted into the mouth of a user). The air/aerosol pathway passes alongside/in the vicinity of the aerosol generator, such that vapour generated from the aerosol generator may be entrained in air passing through the air/aerosol pathway in order to be delivered to the user. The area surrounding the aerosol-generator thereby forms an aerosol generation area. The device part comprises suitable components to enable and control the aerosol generation, e.g., such as an electronics/power chamber (similar to electronics/power chamber 6) containing electrical control circuitry (similar to electrical control circuitry 7) and a power source (similar to power source 8). Power may be provided from the device part to the consumable to cause the aerosol generator to generate aerosol (e.g., via passing a current through the aerosol generator via electrical contacts provided on the cartridge that engage with electrical contacts on the device part).
In accordance with the present disclosure, one or more displays may be provided on the device part of the aforementioned vaping system (in a substantially similar manner to that as described above with respect to the “heat-not-burn” system). In addition, or alternatively, the, or one or more, displays may be provided on the cartridge. The cartridge may be configured to receive an electrical input from the device part to control the one or more displays (if present) on the cartridge. Alternatively, the cartridge may be provided with its own power source and/or controller for controlling the one or more displays (if present) on the cartridge.
