Various devices and systems are available that heat or warm aerosolisable substances as opposed to burning tobacco in conventional tobacco products.
- A commonly available reduced-risk or modified-risk device is the heated substrate aerosol generation device or heat-not-burn device. Devices of this type generate an aerosol or vapor by heating an aerosol substrate that typically comprises moist leaf tobacco or other suitable aerosolisable material to a temperature typically in the range 150° C. to 350° C. Heating 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 by-products 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 require the sugars and other additives that are typically added to such materials to make the smoke and/or vapor more palatable for the user.
- In such devices, the substrate is usually contained substantially in an aerosol generation chamber for heating, and the user usually needs to push a button to eject the substrate out of the aerosol generation chamber after consuming for changing to a new substrate. However, arranging buttons on the device may create gaps on the housing of the aerosol generation device, which reduces the ingress of the aerosol generation device, and may complicate the operation of the device for the user.
- The present invention provides a smoking article for an aerosol generation device, which solves some of or all of the above-mentioned problems.
- A 1st embodiment of the invention is directed to an aerosol generation device, comprising:
-
- an aerosol generation chamber configured to receive and heat a substrate to generate aerosol,
- 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
- an ejection mechanism having a lever and being at least partially engaged with the cover so as to eject at least a portion of the substrate out of the aerosol generation chamber when the cover is in the open position;
- wherein the ejection mechanism can be in an ejected state in which at least a portion of the substrate protrudes from the aerosol generation chamber, and in a non-ejected state in which the substrate is fully contained by the aerosol generation chamber; and
the ejection mechanism translates from the non-ejected state to the ejected state when the cover is moved from the closed position to the open position, thereby ejecting the substrate by rotating the lever.
- The ejection mechanism improves the convenience of using and replacing the aerosol substrate for the user. The substrate can be automatically ejected by just opening the cover. This provides an intuitive and robust way to replace the substrate, and also allows for a simple inner structure of the aerosol generation device.
- According to a 2nd embodiment, in the 1st embodiment, when the cover is moved from the open position to the closed position, the lever rotates back to an original position so as to enter the non-ejected state, in which the aerosol generation chamber is fully inserted with the substrate.
- According to a 3rd embodiment, in any one of the preceding embodiments, the cover can be in an intermediate position between the open position and the closed position, the lever does not rotate when the cover is moved from the closed to the intermediate position, and the lever ejects the substrate by rotating when the cover is moved from the intermediate position to the open position.
- With this arrangement, the substrate is only ejected when the aerosol generation chamber is fully exposed, which avoids incidental operation by the user.
- According to a 4th embodiment, in any one of the preceding embodiments, the lever at least partially defines the bottom surface of the aerosol generation chamber.
- According to a 5th embodiment, in any one of the preceding embodiments, the ejection mechanism has a sliding track, and a sliding block connected with the cover and the lever is arranged to slide in the sliding track so as to trigger the rotation of the lever.
- According to a 6th embodiment, in the preceding embodiment, a fixing mechanism causes the lever to mechanically engage with the sliding block so that the lever rotates when the sliding block slides and vice versa.
- According to a 7th embodiment, in any one of the 5th or 6th embodiments, a protrusion (1021) of the cover is slidingly engaged with a protrusion of the sliding block so that when the cover is moved from the closed position to the open position, or from the open position to the closed position, the lever is pressed down or lifted up, respectively.
- According to an 8th embodiment, in any one of the 5th to 7th embodiments, the protrusion (1021) of the cover and/or the protrusion of the sliding block are made of metal.
- With this arrangement, the life of the ejection mechanism and the device is prolonged.
- According to a 9th embodiment, in any one of the preceding embodiments, the aerosol generation device has an elongated shape, and the cover is arranged to slide in a longitudinal direction of the aerosol generation device.
- Preferred embodiments are now described, by way of example only, with reference to the accompanying drawings.

FIG. 1 : is a schematic illustration of an aerosol generation device with substrates according to an exemplary embodiment of the present invention; -
FIG. 2 : is a schematic illustration of the aerosol generation device according to the exemplary embodiment of the present invention; -
FIGS. 3 a to 3 c : show exposed schematic views of the aerosol generation device in different states according to the exemplary embodiment of the present invention. - Preferred embodiments of the present invention are described hereinafter and in conjunction with the accompanying drawings.
- As used herein, the term “aerosol generation device” “vaporizer system”, “inhaler” or “electronic cigarette” may include an electronic cigarette configured to deliver an aerosol to a user, including an aerosol for smoking. The illustrated embodiments of the aerosol generation system in this invention are schematic.
- Referring to the drawings and in particular to
FIG. 1 , anelectronic cigarette 1 for consuming a substrate is illustrated. Theelectronic cigarette 1 can be used as a substitute for a conventional cigarette. Theelectronic cigarette 1 has a substantially elongated shape comprising acover 102, and amain body 106. Thecover 102 is slidingly engaged with themain body 106 via a slide track (not shown). When taking the surface of thedevice 1 perpendicular to theinsertion direction 21 as the side surfaces of theaerosol generation device 1, the cover is arranged on a side surface of the main body of thedevice 1, and slides along the direction which is perpendicular to the insertion direction of thesubstrate 2. When taking the direction parallel to theinsertion direction 21 as the transverse direction, and the direction perpendicular to theinsertion direction 21 as the longitudinal direction, thecover 102 is arranged to slide in a longitudinal direction of theaerosol generation device 1. Thecover 102 has a closed position 31 covering theaerosol generation chamber 103 when the user consumes thesubstrate 103 and anopen position 33 exposing the opening of theaerosol generation chamber 103 comprised by theaerosol generation device 1 for inserting or discarding thesubstrate 103. Theaerosol generation chamber 33 is vertically orientated in the main body, namely arranged along the transverse direction of thedevice 1. In the present embodiment, there is also an intermediate position between the closed position and the open position. When thecover 102 is slid to the intermediate position, the opening of theaerosol generation chamber 103 is completely exposed. In a preferred embodiment, when thecover 102 is slid from the closed position to the intermediate position, thecover 102 just reveals the complete opening of theaerosol generation chamber 103. - A schematic perspective illustration of the
aerosol generating substrate 2 is shown inFIG. 1 . Thesubstrate 2 may for example comprise nicotine or tobacco, and 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. In some embodiments, the aerosol generating agent may be glycerol, propylene glycol, or a mixture of glycerol and propylene glycol. Thesubstrate 103 may also comprise at least one of a gelling agent, a binding agent, a stabilizing agent, and a humectant. - The
substrate 2 is porous such that air can flow through thesubstrate 2 and collect aerosol as it does so. Thesubstrate 2 may for example be a foam, or packed strands or fibres. Thesubstrate 2 may be formed through an extrusion and/or rolling process into a stable shape. Theaerosol generating substrate 2 may be shaped to provide one air flow channel on one side or, in preferred embodiment, multiple air flow channels as shown inFIG. 1 , more preferably, on both sides. These can be aligned with the air flow channel of the aerosol generatingdevice 1 in order to increase air flow through theaerosol generation chamber 103. Thesubstrate 103 is exposed with a bare external surface. Alternatively, thesubstrate 103 may comprise an air permeable wrapper covering at least part of a surface of thesubstrate 103. The wrapper may, for example, comprise paper and/or non-woven fabric. - In the present embodiment, the substrate may have a substantially flat cuboid shape or a pod shape having a size of 18×12×1.2 mm, with each of length, width and depth of the cuboid being selected within a range of +/−40%, for example. Generally, the length of the substrate in the preferred embodiments is between 40 and 10 mm, preferably between 30 and 12 mm, more preferably between 25 and 14 mm, and most preferably between 22 and 15 mm. The width of the substrate in the preferred embodiments is between 30 and 6 mm, preferably between 25 and 8 mm, more preferably between 20 and 9 mm, and most preferably between 16 and 9 mm. The depth of the substrate in the preferred embodiments is between 3 and 0.5 mm, preferably between 2 and 0.6 mm, more preferably between 1.8 and 0.8 mm, and most preferably between 1.6 and 0.9 mm.
- The aerosol generating substrate is preferably designed to be shorter than or equal to the length of the
aerosol generation chamber 103 in thelongitudinal direction 21 so that the substrates can be fully covered by thecover 102 and completely enclosed and contained in theaerosol generation chamber 103 when the cover is in the closed position of thecover 102. In other words, the aerosol generation chamber 107 has a substantially cuboid shape corresponding the shape of thesubstrate 103, with a size of, e.g., 20×12×1.2 mm, with each of length, width and depth of the cuboid being selected within a range of +/−40%. The length of the aerosol generation chamber is preferably greater than the length of thesubstrate 2, herein 18 mm, and the width and depth of the aerosol generation chamber 107 are preferably greater than the width and depth of thesubstrate 2, which are 12 mm and 1.2 mm, respectively. More specifically, the length of the aerosol generation chamber in the preferred embodiments is between 45 and 11 mm, preferably between 35 and 13 mm, more preferably between 30 and 14 mm, and most preferably between 25 and 15 mm. The width of the chamber in the preferred embodiments is between 31 and 6 mm, preferably between 26 and 8 mm, more preferably between 21 and 9 mm, and most preferably between 17 and 9 mm. The depth of the chamber in the preferred embodiments is between 4 and 0.5 mm, preferably between 3 and 0.6 mm, more preferably between 2.8 and 0.8 mm, and most preferably between 2 and 0.9 mm. - The cuboid of the aerosol generation chamber has two openings on the two opposite ends forming two surfaces perpendicular to the transverse direction. One of the openings (the “first opening”) is configured to be the opening for inserting and discarding the
substrate 2 and can be covered by thecover 102. - Referring to
FIG. 2 , the main body further comprises an ejection mechanism 101 (shown in dark), aLiPo battery 106, aPCBA 104 comprising a controller or a CPU, and a USB-C connector 1063 for charging the LiPo battery 1061 and/or transmitting data to thedevice 1. Theejection mechanism 101 is configured to eject thesubstrate 2 out of theaerosol generation chamber 103 by supporting thesubstrate 2 via the second opening of theaerosol generation chamber 103. Theaerosol generation chamber 103 is engaged with the ejection mechanism. This means that at least a portion of thesubstrate 2 can stick out of the first opening of the aerosol generation chamber automatically when thesubstrate 2 is ejected by the ejection mechanism, and thesubstrate 2 can be taken out by the hand of the user after the cover is opened. - Before using the
device 1 and consuming thesubstrate 2, the user first opens thecover 102 of thedevice 1 by sliding thecover 102 along the longitudinal direction till the intermediate position or the open position. The user then inserts thesubstrate 103 into the first opening of theaerosol generation chamber 103 along theinsertion direction 21. The user then closes thecover 102 by sliding it to the closed position 31. The user switches on the device by means of a button on thedevice 1, and starts consuming thesubstrate 2. In an alternative embodiment, sensors may be arranged in thedevice 1 so as to sense the closing of the cover and/or the existence of thesubstrate 2 in thedevice 1, which then trigger the heating for thesubstrate 2 automatically. After the user has finished consuming thesubstrate 2, the user simply opens thecover 2 until the cover is slid to theopen position 33. At least a part of thesubstrate 2 pops up and sticks out automatically from the first opening of theaerosol generation chamber 103. In a preferred embodiment, a sensor is configured to sense the opening of thecover 102 so as to stop the heating of theaerosol generation chamber 103. Finally, the user discards thesubstrate 2 from thedevice 1. - The specific configuration of the
ejection mechanism 101 is illustrated inFIGS. 3 a to 3 c. - The
ejection mechanism 101 at least indirectly connects withaerosol generation chamber 103 and thecover 102, and is at least partially engaged with thecover 102. Theejection mechanism 101 comprises alever 1011 similar to or in the form of a seesaw. Thelever 1011 has two straight beams or rods pivoted at a fixed hinge in thedevice 1. The two beams are integrated into one piece and fixedly form a predetermined angle. A top end of one of the two beams is configured to support the substrate as a bottom (the internal lower surface or the floor) of theaerosol generation chamber 103 while thesubstrate 2 is heated, and protrudes into theaerosol generation chamber 103. Thus, at least a part of thesubstrate 2 is ejected out of the first opening of theaerosol generation chamber 103 when thecover 102 is slidingly opened. The leverage movement of thelever 1011 is triggered by thecover 102 and can be separated into two states: an ejected state and a non-ejected state. In the ejected state, thesubstrate 2 protrudes from theaerosol generation chamber 103, and in the non-ejected state, thesubstrate 2 is fully contained by theaerosol generation chamber 103. Theejection mechanism 101 transitions from the non-ejected state to the ejected state when thecover 102 is moved from the closed position 31 to theopen position 33, thereby ejecting thesubstrate 2 by rotating thelever 1011. More specifically, thelever 1011 does not rotate when thecover 102 is slid from the closed position 31 to the intermediate position 32, and thelever 1011 ejects thesubstrate 2 by the leverage movement when thecover 102 is slid from the intermediate position 32 to theopen position 33. - The ejection mechanism further comprises a sliding
track 1013 in which a slidingblock 1012 is arranged and configured to engage with the cover and the lever so as to trigger the leverage movement of thelever 1011. The slidingtrack 1013 is arranged along the transverse direction of thedevice 1, wherein the slidingblock 1012 moves along the same axis. Along that axis, the sliding block has two opposite ends. The first end has an inclined plane surface, and at least a part of the second end forms an arc. Thecover 102 comprises a protrusion having an inclined plane surface which slidingly engages and cooperates with the inclined surface of the slidingblock 1012 between the intermediate position 32 and theclosed position 33. In other words, when the cover moves from the intermediate position 32 to theclosed position 33, the inclined surface of the protrusion of thecover 102 presses the slidingblock 1012 so that it moves downwards, the arc of the slidingblock 1012 presses down one beam of thelever 1011, and the other beam of thelever 1011 is lifted up because of the leverage movement. - In a preferred embodiment, at least parts of the ejection mechanism comprise or are preferably made of metal material; preferably the
protrusion 1021 of thecover 102 and/or the inclining surface of the slidingblock 1012 are made of metal. - In another preferred embodiment, a fixation mechanism (not shown) is configured to cause the
lever 1011 to mechanically engage with the arc of the slidingblock 1012 so that thelever 1011 rotates when the slidingblock 1012 slides and vice versa. More specifically, in one embodiment, a spring may be arranged underneath the beam of thelever 1011. In another embodiment, a ring may be configured on the slidingblock 1012 through which the beam of thelever 1011 extends. In yet another embodiment, magnets may be arranged in thelever 1011 and the slidingblock 1012. Having this fixation mechanism, the beam of the lever rotates and moves together with the slidingblock 1012 and thecover 102. Thesubstrate 2 is thus automatically inserted into theheating chamber 103 from theclosed position 33 to the intermediate position 32 with the beam of thelever 1011, which supports thesubstrate 2, rotating down. - In other embodiments, the
device 1 may be not configured with the fixation device. The user may insert thesubstrate 2 into theaerosol generation chamber 102 when thecover 102 is in theopen position 33. Since the beam of thelever 1011 close to the heating chamber is lifted up and protrudes in theaerosol generation chamber 102, thesubstrate 2 also at least partially protrudes out of theaerosol generation chamber 102. The user may simply hold thedevice 1 horizontally so that with the weight of thesubstrate 2, the lever resets back due to gravity when the cover is slid from the intermediate position 32 to the closed position 31. - Hereinafter, the process performed by and the different states of the
ejection mechanism 101 in thedevice 1, more specifically the ejected state and the non-ejected state, are discussed with reference toFIGS. 3 a to 3 c. - In
FIGS. 3 a and 3 b , theejection mechanism 101 is in the non-ejected state. Thesubstrate 2 is fully inserted in theaerosol generation chamber 103. One beam of thelever 1011, which supports thesubstrate 2, is pressed down by the substrate, and the other beam of thelever 1011 is lifted up together with the slidingblock 1012. - When the user slides the cover in the longitudinal direction from the closed position 31 to the intermediate position 32, the ejection device remains in the non-ejected state. The distance L1 between the protrusion of the
cover 102 and the end of the cover which covers theaerosol generation chamber 103 is configured to be longer than the width of theaerosol generation chamber 103. With this arrangement, thelever 1011 starts to rotate and pivoted at the fixed hinge, or fulcrum in the device, when the cover is slid to the intermediate position 32, so that thesubstrate 2 and the first opening of theaerosol generation chamber 103 are fully exposed during the transition from the non-ejected state to the ejected state. -
FIG. 3 c shows the ejected state of theejection mechanism 101. The cover is slid to theopen position 33. A stop structure (not shown) is arranged in thedevice 1 to stop thecover 102 from sliding back any further. A fixation structure (not shown) may also be arranged in thedevice 1, so as to make thecover 102 bi-stable, i.e. it can stably maintain the position in the open state or in the closed state. The fixation structure may consist of center springs or magnets. The slidingblock 1012 is pressed by the protrusion of thecover 102, which has a trapezoid shape, and slid down. - The beam of the
lever 1011 which connects with the slidingblock 1012 is pressed down, while the other beam of thelever 1011 is lifted up and protrudes into theaerosol generation chamber 103. Thesubstrate 2 is supported and sticks out of the aerosol generation device for the user to discard it out of the device.
