Definitions
- the present disclosure relates to an aerosol generation device in which an aerosol generating substrate is heated to form an aerosol.
- the disclosure is particularly applicable to a portable aerosol generation device, which may operate at low temperature.
- Such devices may heat, rather than burn, tobacco or other suitable aerosol substrate materials by conduction, convection, and/or radiation, to generate an aerosol for inhalation.
- Devices of this type generate an aerosol or vapour by heating an aerosol substrate that typically comprises moist leaf tobacco or other suitable solid aerosolisable material to a temperature typically in the range 150 °C to 350 °C. Heating such an aerosol substrate, but not combusting or burning it, releases an aerosol that comprises the components sought by the user but not the toxic and carcinogenic byproducts of combustion and burning. Furthermore, the aerosol produced by heating the tobacco or other aerosolisable material does not typically comprise the burnt or bitter taste resulting from combustion and burning that can be unpleasant for the user and so the substrate does not therefore require the sugars and other additives that are typically added to such materials to make the smoke and/or vapour more palatable for the user. In such devices, the aerosol substrate is heated by a heating element, for example in a heating chamber. The aerosol substrate is consumed through generation of the aerosol and must be regularly replaced. It is therefore desirable to provide a convenient way of replacing the aerosol substrate in the heating chamber.
- an aerosol generation device comprising: An aerosol generation chamber configured to receive and heat a substrate to generate aerosol, the aerosol generation chamber comprising at least a heating element; an oblong housing; a cover which can be in a closed position covering the aerosol generation chamber and in an open position exposing the aerosol generation chamber; and a tray configured to receive and hold the substrate, the tray being connected to the cover; wherein when the cover is in the open position, the tray can receive the substrate, and the received substrate is located at least partly outside of the aerosol generation chamber, and when the cover is in the closed position, a received substrate is fully contained in the aerosol generation chamber and in contact with the heating element; and wherein the cover can be moved from the open position to the closed position by rotation, whereby the tray is translated in a longitudinal direction of the housing and towards the heating element and in a direction substantially perpendicular to the longitudinal direction of the housing such that a substrate held by the tray is put in contact with the heating element.
- the tray provides an intuitive and robust way to replace the aerosol substrate consumable by removing a used substrate from the tray and putting an unused substrate on the tray.
- the substrate is then moved into the aerosol generation chamber, providing a simple and intuitive way for a user to place the substrate in the right position. Additionally, by movement of the tray into the aerosol generation chamber, the substrate is put in contact with the heating element, thereby improving aerosol generation efficiency.
- the tray comprises means for fixing the substrate to the tray.
- the means for fixing are one or more protrusions which can engage with respective recesses of the substrate.
- the recesses can be formed by stamping the substrate with the one or more protrusions.
- no recesses must be formed in the substrate during production, making the substrate more cost-efficient by saving one production step.
- a flexible substrate can then be “stamped” by means of the protrusions on the tray to fulfil the same purpose as a previously provided recess.
- the movement of the tray in the direction substantially perpendicular to the longitudinal direction of the housing is caused by a slanted wall of the aerosol generation chamber.
- a slanted wall provides a straight-forward and durable way to guide the tray towards the desired position.
- the slanted wall therefore ensures that the substrate is in contact and/or press towards the heating element, thus improving aerosol generation efficiency.
- a cross-section of the tray has a generally L-shaped configuration, the long leg of the L-shape being oriented substantially parallel to the longitudinal direction of the housing, and the short leg extending from the long leg towards the heating element.
- a L-shaped tray ensures that a substrate placed on the tray does not slide downwards from the tray. Furthermore, the short leg eases handling of the device, as a user can easily insert a substrate which is then held in place by the short leg of the L- shaped tray. Thus, it provides a way of intuitive handling while improving aerosol generation efficiency of the device.
- the cover is connected to the housing by means of a hinge which allows for the rotation of the cover.
- connection to the housing ensures that the cover is not lost when the device is not in use.
- the rotational hinge provides an intuitive way of handling the device for a user.
- the cover is biased towards the closed position.
- the biasing is realized by means of a spring.
- the tray is connected to the cover such that the rotation of the cover around the hinge results in the translation the tray.
- connection between the tray and the cover is realized by means of a second hinge, the second hinge being distanced from the hinge which allows for the rotation of the cover.
- the tray moves towards the center of the housing along the longitudinal direction of the housing as the cover moves from the open position to the closed position, and in the opposite direction as the cover moves from the closed position to the open position.
- the substrate is moved away from the center of the housing along the longitudinal direction of the housing by means of the short leg when the cover moves from the closed position to the open position.
- the substrate is moved away from the center of the housing along the longitudinal direction of the housing by means of the means for fixing the substrate to the tray.
- the substrate has the shape of a plate, pad, or disk.
- a substrate having such a shape is substantially flat and can easily be put in contact with a substantially flat heating element, ensuring permanent contact and improving aerosol generation efficiency. Also, the ratio between the surface in contact with the heating element and the volume of the substrate is relatively large, thereby further increasing aerosol generation efficiency.
- the substrate has an upper surface and a lower surface, and in the closed position of the cover the lower surface is in contact with the long leg of the tray, and the upper surface is in contact with the heating element.
- a substrate may be fixed between the tray and the heating element and pressed towards the heating element by movement of the long leg of the tray towards the heating element.
- At least one of the side surfaces of the substrate when received by the tray is in contact with the short leg.
- Figure 1 shows the aerosol generation device in side view, with the cover in open position.
- Figure 2 shows the aerosol generation device in side view, with the cover in closed position.
- Figure 3 shows a cross-sectional side view of the aerosol generation device, with the cover in open position and a substrate being inserted in the device.

- the aerosol substrate may for example comprise nicotine, tobacco and/or an aerosol former.
- Tobacco may take the form of various materials such as shredded tobacco, granulated tobacco, tobacco leaf and/or reconstituted tobacco.
- Suitable aerosol formers include: a polyol such as sorbitol, glycerol, and glycols like propylene glycol or triethylene glycol; a non-polyol such as monohydric alcohols, acids such as lactic acid, glycerol derivatives, esters such as triacetin, triethylene glycol diacetate, triethyl citrate, glycerin or vegetable glycerin.
- the aerosol generating agent may be glycerol, propylene glycol, or a mixture of glycerol and propylene glycol.
- the substrate may also comprise at least one of a gelling agent, a binding agent, a stabilizing agent, and a humectant.
- the aerosol substrate may be porous such that air can flowthrough the substrate and collect aerosol as it does so.
- the substrate may for example be a foam, or packed strands or fibres.
- the substrate maybe formed through an extrusion and/or rolling process into a stable shape.
- the aerosol generating substrate may be shaped to provide one air flow channel or multiple air flow channels. These can be aligned with the air flow channel of the aerosol generating device in order to increase air flow through the heating chamber.
- the substrate is exposed with a bare external surface.
- the substrate may comprise an air-permeable wrapper covering at least part of a surface of the aerosol generating substrate.
- the wrapper may, for example, comprise paper and
- the aerosol generation chamber 15 may simply be an interior volume of the housing 2, but the aerosol generation chamber 15 is preferably enclosed by an insulating enclosure within the housing 11, so that additional components such as control circuitry and an electrical power source (not shown) are insulated from heat provided within the aerosol generation chamber 15.
- the housing may generally be made from any rigid material such as a thermoplastic or a metal (e.g. aluminium).
- the insulating enclosure may be made from a heat-resistant material such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT), or polyamide (PA) in order to prevent thermal deformation or melting.
- the heat resistant material may be a super engineering plastic such as polyimide (PI), polyphenylenesulfide (PPS) or polyether ether ketone (PEEK).
- the substrate 11 is positioned in the aerosol generation chamber 15 by inserting a tray 5 carrying the substrate 11 into the aerosol generation chamber 15.
- the substrate can be placed onto the tray when a cover 7 is in an open position.
- the tray 5 is guided into a position where the substrate 11 is held in the aerosol generation chamber 15, as depicted in Fig. 6.
- the tray 5 may also be in a second position, where the substrate 11 can be placed onto or removed from the tray 5.
- the aerosol generation device 1 may comprise a pump for pumping air towards the mouthpiece 3 to provide the aerosol.
- an aerosol generation device 1 is illustrated.
- the device may comprise an oblong housing 2, and a mouthpiece 3 which can be used to suck the generated aerosol out of the device.

- Tray 5 may comprise a protrusion 6 or other means to fixate a substrate which may be inserted by a user.
- the cover 7 may be translated into the closed position by rotating it in rotational direction 8 around hinge 16.
- Figure 2 depicts the same embodiment of the aerosol generation device 1 as Figure 1. However, in Figure 2, the cover 7 is in closed position, covering aerosol generation chamber 15. From the closed position, the cover can be translated back to the open position by rotating it in the opposite direction of rotational direction 8.
- Figure 3 depicts a cross-sectional view of the embodiment of aerosol generation device 1, with the cover 7 in open position.
- Cover 7 is rotatably mounted to the housing 2 by means of a first hinge 16.
- the first hinge 16 may be located in a rotation element which may be rigidly connected to cover 7.
- different solutions are possible, such as a hinge which is placed directly on the cover, a lever, or the like.
- hinge 16 may be loaded by a spring to be biased towards the closed position.
- the device 1 has to be actively opened by a user, but will close by means of the spring, if the cover 7 is not held in the open position by the user.
- hinge 16 may not be biased towards the closed position, such that a user has to actively bring cover 7 into the closed position by rotating cover 7 around hinge 16 in rotational direction 8.
- the aerosol generation chamber 15 comprises one or more heating elements 10 configured to heat and generate aerosol from a substrate 11.
- the heating elements are preferably electric heating elements, such as resistive heating elements, but any type of heating element suitable for supplying heat to the aerosol generation chamber 15 may be used.
- the heating element 10 preferably has a substantially flat configuration but may have different shapes in some embodiments.
- the heating element 10 may be powered by an electrical power source such as a removable battery, a rechargeable battery or the like.
- an electrical power source such as a removable battery, a rechargeable battery or the like.
- the electrical circuitry needed for powering the heating element is known to the skilled person and is therefore not discussed here.
- the tray 5 has L-shaped configuration with a long leg 21 and a short leg 22.
- the short leg 22 is configured to be placed underneath a substrate 11 to prevent the substrate from sliding downwards due to gravitational force.
- the long leg is configured to be put in contact with a flat surface of substrate 11 to control the substrate’s position relative to the heating element 10.
- the long leg 21 may comprise a protrusion 6 configured to lock onto a respective recess 23 in a substrate 11.
- a flexible substrate may be used, such that when pressure is applied to the substrate 11 by means of the long leg 21 of the L-shaped tray 5, a recess 23 is formed in the substrate 11 by stamping.
- This fixing ensures that the substrate 11 is held in the correct position with respect to the heating element 10, and also ensures that during movement from the closed position to the open position, the substrate is lifted back up with the tray. This is especially important for possible embodiments which do not comprise an L-shaped tray 5-
- FIG. 5 illustrates the aerosol generation device 1 in a state ready to generate aerosol, where the cover 7 is in the closed position, and the substrate 11 is inside the aerosol generation chamber 15.
- the substrate herein is heated by heating element 10 and an aerosol can be generated.
- the aerosol may then be provided to a user through mouthpiece 3.
- Fig. 6 depicts the aerosol generation device 1 with the cover 7 in the open position. After consuming of the aerosol by the user, said user may bring cover 7 back into the open position by rotation in opposite rotational direction 28. Rotational element 19 again translates the rotation into a translation and causes the tray to be lifted from the aerosol generation chamber. By means of the short leg 22 of the L- shaped tray 5 and/ or the protrusion 6 of the tray and the recess 23 in the substrate 11, the substrate 11 is lifted out of the aerosol generation chamber 15 together with the tray. From there, substrate 11 may be removed by the hand of a user and may be replaced by an unused substrate.
