Further features and advantages of the invention will become apparent from the following description of preferred embodiments of the invention, given by way of example only, which is made with reference to the accompanying drawings.
Aerosol-generating material is a material that is capable of generating aerosol, for example when heated, irradiated or energized in any other way. Aerosol-generating material may, for example, be in the form of a solid, liquid or gel which may or may not contain an active substance and/or flavorants. In some embodiments, the aerosol-generating material may comprise an “amorphous solid”, which may alternatively be referred to as a “monolithic solid” (i.e. non-fibrous). In some embodiments, the amorphous solid may be a dried gel. The amorphous solid is a solid material that may retain some fluid, such as liquid, within it. In some embodiments, the aerosol-generating material may for example comprise from about 50 wt %, 60 wt % or 70 wt % of amorphous solid, to about 90 wt %, 95 wt % or 100 wt % of amorphous solid.
The aerosol-generating material may comprise one or more active substances and/or flavors, one or more aerosol-former materials, and optionally one or more other functional material.
The active substance as used herein may be a physiologically active material, which is a material intended to achieve or enhance a physiological response. The active substance may for example be selected from nutraceuticals, nootropics, psychoactives. The active substance may be naturally occurring or synthetically obtained. The active substance may comprise for example nicotine, caffeine, taurine, theine, vitamins such as B6 or B12 or C, melatonin, cannabinoids, or constituents, derivatives, or combinations thereof. The active substance may comprise one or more constituents, derivatives or extracts of tobacco, cannabis or another botanical.
In some embodiments, the active substance comprises nicotine. In some embodiments, the active substance comprises caffeine, melatonin or vitamin B12.
The one or more other functional materials may comprise one or more of pH regulators, colouring agents, preservatives, binders, fillers, stabilizers, and/or antioxidants.
The aerosol-former material may comprise one or more constituents capable of forming an aerosol. In some embodiments, the aerosol-former material may comprise one or more of glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3-butylene glycol, erythritol, meso-Erythritol, ethyl vanillate, ethyl laurate, a diethyl suberate, triethyl citrate, triacetin, a diacetin mixture, benzyl benzoate, benzyl phenyl acetate, tributyrin, lauryl acetate, lauric acid, myristic acid, and propylene carbonate.
A consumable is an article comprising or consisting of aerosol-generating material, part or all of which is intended to be consumed during use by a user. A consumable may comprise one or more other components, such as an aerosol-generating material storage area, an aerosol-generating material transfer component, an aerosol generation area, a housing, a wrapper, a mouthpiece, a filter and/or an aerosol-modifying agent. A consumable may also comprise an aerosol generator, such as a heater, that emits heat to cause the aerosol-generating material to generate aerosol in use. The heater may, for example, comprise combustible material, a material heatable by electrical conduction, or a susceptor.
In this example, the non-combustible aerosol provision device 100 is for heating aerosol-generating material in a consumable to volatilise at least one component of the aerosol-generating material. The non-combustible aerosol provision device 100 is hereafter referred to as the device 100. The device 100 is configured to heat the aerosol-generating material in a consumable comprising aerosol-generating material (not shown in
A susceptor is a material that is heatable by penetration with a varying magnetic field, such as an alternating magnetic field. The susceptor may be an electrically-conductive material, so that penetration thereof with a varying magnetic field causes induction heating of the heating material. The heating material may be magnetic material, so that penetration thereof with a varying magnetic field causes magnetic hysteresis heating of the heating material. The susceptor may be both electrically-conductive and magnetic, so that the susceptor is heatable by both heating mechanisms. The device that is configured to generate the varying magnetic field may also be referred to as a magnetic field generator.
In some examples, the heating arrangement 104 is an induction heating arrangement and is configured to generate a varying magnetic field in order to inductively heat a susceptor. In some examples, the susceptor is configured to define the heating chamber 102 for receipt of the consumable, as will be described below in more detail. The induction heating arrangement may comprise one or more inductors through which an alternating current is passed to generate the varying magnetic field. In some examples using induction heating, the heating arrangement 104 comprises one or more susceptors. In other examples using induction heating, the heating arrangement 104 may not comprise a susceptor and one or more susceptors may instead be provided as part of/with consumables intended for use with the device 100.
The device 100 comprises a power source 106. The power source 106 supplies electrical power to the various components of the device 100. In some examples, the power source 106 is a battery. In some examples, the power source 106 comprises a battery and a DC-DC converter, and power is supplied from the battery through the DC-DC converter. The DC-DC converter may allow the power supply 106 to supply power at a different voltage to the voltage of the battery. In some examples, the device 100 may comprise a DC to AC converter for converting a DC current from, e.g., a battery to AC current, for example, to supply power to one or more inductors of the heating arrangement 104 where the heating arrangement 104 is an induction heating arrangement. In the following examples, the power source 106 is referred to simply as the battery 106.
In the example of
The device 100 comprises a housing 101 which forms an outer cover of the device 100 and surrounds and houses various components of the device 100. The chamber 102 in this example is configured to receive a consumable (not shown in
The device 100 has an opening 105 in one end, which allows the consumable to be inserted into the chamber 102. As shown in certain examples below, in some examples a portion of the consumable may be received in the chamber 102 of the device 100, while a portion of the consumable may protrude from the opening 105 of the device 100. In examples, the portion of the consumable received in the chamber 102 comprises the aerosol-generating material from which the device 100 is configured to generate aerosol. The portion of the consumable which protrudes from the opening 105 may, for example, comprise a filter or the like, and the user may inhale the generated aerosol from the portion of the consumable which protrudes from the opening 105.
The device 100 may comprise a user-operable control element 112, such as a button or switch, which operates the device 100 when pressed. For example, a user may turn on the device 100 by operating the switch 112.
The device 100 may also comprise an electrical component, such as a socket/port (not shown), which can receive a cable to charge the battery 106. For example, the socket may be a charging port, such as a USB charging port. In some examples the socket may be used additionally or alternatively to transfer data between the device 100 and another device, such as a computing device. The socket may also be electrically coupled to the battery 106 via electrical tracks.
The end of the device closest to the opening 105 may be known as the proximal end (or mouth end) of the device 100 because, in use, it is closest to the mouth of the user. In use, a user may insert the consumable into the opening 105, operate the user control 112 to begin heating the aerosol-generating material and draw on the proximal end of the device 100. This causes the aerosol to flow through the device 100 along a flow path towards the proximal end of the device 100. In examples, a portion of the consumable may protrude from the opening 105 and the user may draw on a proximal end of the consumable to cause the aerosol to flow to the proximal end of the device 100 to be inhaled. In other examples, the device 100 may comprise a mouthpiece on which the user inhales to draw the flow of aerosol.
An end of the device 100 opposite the proximal end and furthest away from the opening 105 may be known as the distal end of the device 100 because, in use, it is the end furthest away from the mouth of the user. As a user draws on the aerosol generated in the device, the aerosol flows away from the distal end of the device 100.
The device 100 may in some examples comprise a lid/cap (not shown), arranged towards the distal end of the device 100. Opening the lid/cap may provide access to the heating chamber 102. A user may, for example, open the second lid to clean components in the heating chamber 102, e.g. to remove debris from previous usage sessions.
The device 100 comprises a consumable holder 500. The consumable holder 500 is configured to hold in position, one at a time, each of a plurality of differently-sized consumables intended for use with the device 100. For example, the consumable holder 500 may allow for the device 100 to receive a first consumable and a second consumable which may have different lengths and/or different diameters to one another. It should be noted that, herein, reference to consumables of different sizes or to differently-dimensioned consumables refers to consumables which are intended to be a different size to another, and does not, for example, refer to consumables which are intended to be the same size but differ in size by some small amount due to, e.g., manufacturing tolerances. The consumables may, for example, be of different types to one another wherein each of the different types of consumables is intended to have different dimensions.
In some examples, the first consumable and the second consumable are elongate consumables, each of which may, for example, be substantially cylindrical. The first and second consumables both comprise aerosol-generating material. The first and second consumables may, for example, comprise a distal portion containing the aerosol-generating material. The first and second consumables may also comprise a proximal portion which may comprise, for example, a filter and/or other components. Examples of the first and second consumables are described in more detail below, with reference to later figures.
It will be appreciated that the device 100 may comprise other components not shown in
The housing 101 can be seen to form an outer cover of the device 100 which surrounds and houses various components of the device 100. The device 100 has an opening 105 in one end, through which a consumable for use with the device 100, such as the first consumable 120a, may be inserted for heating by the heating assembly 104 (not shown in
The device 100 may also comprise an electrical component, such as a socket/port 114, which can receive a cable to charge a battery of the device 100. For example, the socket 114 may be a charging port, such as a USB charging port. In some examples the socket 114 may be used additionally or alternatively to transfer data between the device 100 and another device, such as a computing device. The socket 114 may also be electrically coupled to the battery 106 via electrical tracks.
The device 100 may further comprise an insulating member (not shown) which may be generally tubular and at least partially surround the heating chamber 102. The insulating member 128 may be constructed from any insulating material, such as a plastics material for example. In this particular example, the insulating member is constructed from polyether ether ketone (PEEK). The insulating member may help insulate the various components of the device 100 from the heat generated to heat the consumable 120.
The consumable holder 500 is configured to hold the first consumable 120a (not shown in
As mentioned above, the consumable holder 500 is configured to hold any of a plurality of t consumable, each having different dimensions, and the consumable holder 500 will now be described in more detail.
The consumable holder 500 comprises selectively engageable gripping members for engaging and holding a consumable in the chamber. In the example shown in
In this example, each of first and second gripping members 510, 520 is annular and defines a central aperture 512a, 522a through which the consumable 120 to be held is received. The first gripping member 510 comprises a ring 512b and a plurality of gripping arms 512c depending from the ring 512b. The gripping arms 512c surround the central aperture 512a and the position of the gripping arms 512c defines a diameter of the central aperture 512a. Each of the gripping arms 512c has a free end having an inwardly turned portion 512d for gripping a point on the consumable. The inwardly turned portions 512d of the gripping arms 512c are configured to grip the point on the consumable when the free ends of the gripping arms 512c are moved in a radial direction with respect to the ring 512b.
The frame 540 comprises a first ring 542 and a second ring 544. The first ring 542 is mounted over the first gripping member 510. The first ring 542 is configured to constrict the gripping arms 512c of the first gripping member 510 when the frame 540 is caused to move axially downwards by a user. The first ring 542 is a ring of a fixed diameter which surrounds and is in contact with first gripping member 510. When the first ring 542 is moved axially downward the first ring 542 forces the radially outwardly biased arms 512 radially inward. As the point of contact between the first ring 542 and the arms 512 moves downwards and becomes closer to the free ends of the arms 512c, the inwardly turned portions 512d of the arms 512c are forced radially inward and are caused to grip the consumable 120.
The second gripping member 520 works in the same manner as described for the first gripping member 510 to grip a point towards a distal end of the consumable 120. The second gripping member 520 defines a central aperture 522a, and comprises a ring 522b, and a plurality of gripping arms 522c, each of the gripping arms 522c having an inwardly turned portion 522d at its free end. Similarly, the frame comprises a second ring 544 surrounding the second gripping member 520 and configured to constrict the arms 522c of the second gripping member 520 to cause it to grip the consumable 120 when the frame 540 is moved axially downwards.
Inward radial movement of the free ends 512d of the gripping arms reduces a diameter of the aperture 512a causing the free ends 512d to engage and grip the consumable 120. The gripping arms 522c are biased radially outwardly such that the aperture 522a has a maximum diameter when the gripping arms 522c are not constricted by the frame 540.
The consumable holder 500 is configured to hold consumables having different diameters depending on the location of the frame 540, as is shown in
The consumable holder 500 provides a convenient and flexible way of holding different consumables having different dimensions in the heating chamber 102 of the device 100. Since the diameter which the gripping members 510, 520 are configured to grip is adjustable by a user, the consumable holder 500 can be used to grip consumable having various different diameters. The frame 540 is movable in a continuous manner along the axial direction and so, although only shown with two different consumables 120a, 120b of different diameter in the figures, the consumable holder 500 can hold consumables having any of a range of diameters falling in the range of diameters between which the apertures 512a, 522a are configurable. Furthermore, since the consumable holder 500 comprises two gripping members 510, 520, any consumable held by the consumable holder 500 is held firmly in position for use.
Another feature of the consumable holder 500 in the example shown in
In some examples, it may be preferable for the proximal end of a consumable inserted into the chamber 102 to protrude from the heating chamber aperture 104 by a given amount, regardless of the length of the consumable. In the example shown in
The above embodiments are to be understood as illustrative examples of the invention. Further embodiments of the invention are envisaged. It is to be understood that any feature described in relation to any one embodiment may be used alone, or in combination with other features described, and may also be used in combination with one or more features of any other of the embodiments, or any combination of any other of the embodiments. Furthermore, equivalents and modifications not described above may also be employed without departing from the scope of the invention, which is defined in the accompanying claims.
