Description

[Technical Field]

[0001] The present disclosure relates to an aerosol-generating device that heats an aerosol-generating substrate to form an aerosol, and more particularly to an aerosol-generating device that includes a lever-based ejection mechanism. [Background technology]

[0002] Over the past few years, the popularity and use of aerosol-generating devices (also known as heat-not-burn products or vaporizers or e-cigarettes) has grown rapidly. As opposed to burning tobacco in traditional tobacco products, a variety of devices and systems are available for heating or warming aerosolizable materials.

[0003] Commonly available risk reduction or risk modification devices are substrate-heated aerosol generating devices or non-combustion heated devices. This type of device typically generates an aerosol or vapor by heating an aerosol substrate containing moist tobacco or other suitable aerosolizable material, typically to temperatures ranging from 150°C to 350°C. By heating, rather than burning or combusting, the aerosol substrate releases an aerosol containing the ingredients desired by the user but without the toxic and carcinogenic by-products of combustion and burning. Furthermore, because aerosols produced by heating tobacco or other aerosolizable material typically do not contain the burnt or bitter taste resulting from combustion, which can be unpleasant to users, the substrate does not require sugars and other additives typically added to such materials to make the smoke and / or vapor more palatable to users.

[0004] In such devices, the substrate is typically contained substantially within the aerosol-generation chamber for heating, and the user typically must press a button to eject the substrate from the aerosol-generation chamber after it has been consumed so that it can be replaced with a new substrate. However, the placement of the button on the device can result in gaps in the housing of the aerosol-generation device, which can narrow the entrance to the aerosol-generation device and make it more difficult for the user to operate the device. Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention provides a smoking article for an aerosol-generating device that solves some or all of the above problems. [Means for solving the problem]

[0006] A first embodiment of the present invention relates to an aerosol generating device, the device comprising: an aerosol generation chamber configured to contain and heat a substrate to generate an aerosol; a cover that can be in a closed position covering the aerosol-generation chamber and in an open position exposing the aerosol-generation chamber; an ejection mechanism having a lever and at least partially engaging the cover when the cover is in an open position to eject at least a portion of the substrate out of the aerosol-generation chamber; the ejection mechanism is capable of being in an ejecting state in which at least a portion of the substrate protrudes from the aerosol-generation chamber, and in a non-ejecting state in which the substrate is completely contained within the aerosol-generation chamber; The ejection mechanism transitions from a non-ejecting state to an ejecting state when the cover moves from the closed position to the open position, thereby ejecting the substrate by rotating the lever.

[0007] This ejection mechanism improves the user's convenience when using and replacing the aerosol substrate. Simply opening the cover allows the substrate to be automatically ejected. This provides an intuitive and reliable method for replacing the substrate, and also simplifies the internal structure of the aerosol generating device.

[0008] According to the second embodiment, in the first embodiment, when the cover is moved from the open position to the closed position, the lever rotates back to its original position to assume a non-ejecting state, in which the substrate is fully inserted into the aerosol-generation chamber.

[0009] According to a third embodiment, in any one of the preceding embodiments, the cover can be in an intermediate position between the open position and the closed position, and when the cover moves from the closed position to the intermediate position, the lever does not rotate, and when the cover moves from the intermediate position to the open position, the lever rotates to eject the substrate.

[0010] In this configuration, the substrate is only ejected when the aerosol-generation chamber is fully exposed, thereby avoiding accidental manipulation by the user.

[0011] According to a fourth embodiment, in any one of the preceding embodiments, the lever at least partially defines a bottom surface of the aerosol-generation chamber.

[0012] According to a fifth embodiment, in any one of the preceding embodiments, the ejection mechanism has a slide track, and a slide block connected to the cover and the lever is arranged to slide within the slide track and trigger rotation of the lever.

[0013] According to the sixth embodiment, in the immediately preceding embodiment, the locking mechanism mechanically engages the lever with the sliding block such that as the sliding block slides, the lever rotates, and vice versa.

[0014] According to the seventh embodiment, in either the fifth or sixth embodiments, the protrusion (1021) of the cover is slidingly engaged with the protrusion of the slide block so that when the cover moves from the closed position to the open position or from the open position to the closed position, the lever is depressed or lifted, respectively.

[0015] According to the eighth embodiment, in any one of the fifth to seventh embodiments, the protrusion (1021) of the cover and / or the protrusion of the slide block is made of metal.

[0016] This configuration increases the life of the ejection mechanism and the device.

[0017] According to a ninth embodiment, in any one of the preceding embodiments, the aerosol generating device has an elongated shape, and the cover is configured to slide in the vertical direction of the aerosol generating device.

[0018] Preferred embodiments will now be described, by way of example only, with reference to the accompanying drawings, in which: [Brief explanation of the drawings]

[0019] [Figure 1] 1 is a schematic diagram of an aerosol generating device having a substrate according to an exemplary embodiment of the present invention. [Figure 2] 1 is a schematic diagram of an aerosol generating device according to an exemplary embodiment of the present invention. [Figure 3] 1A-1C show schematic exposure diagrams of an aerosol generating device in different states according to an exemplary embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0020] Preferred embodiments of the present invention will now be described in conjunction with the accompanying drawings.

[0021] As used herein, the terms "aerosol generating device," "vaporizer system," "inhaler," or "electronic cigarette" may include an electronic cigarette configured to deliver an aerosol, including a smoking aerosol, to a user. The illustrated embodiments of the aerosol generating system of the present invention are schematic.

[0022] Referring to the drawings, and particularly to FIG. 1 , an electronic cigarette 1 for consuming a substrate is shown. The electronic cigarette 1 may be used as a replacement for a conventional cigarette. The electronic cigarette 1 has a substantially elongated shape including a cover 102 and a body 106. The cover 102 is slidably engaged with the body 106 via a slide track (not shown). If the surface of the device 1 perpendicular to the insertion direction 21 is defined as the side of the aerosol generating device 1, the cover is disposed on the side of the body of the device 1 and slides along a direction perpendicular to the insertion direction of the substrate 2. If the direction parallel to the insertion direction 21 is defined as the horizontal direction and the direction perpendicular to the insertion direction 21 is defined as the vertical direction, the cover 102 is configured to slide in the vertical direction of the aerosol generating device 1. The cover 102 has a closed position 31, which covers the aerosol-generation chamber 103 when the user consumes the substrate 103, and an open position 33, which exposes the opening of the aerosol-generation chamber 103 included in the aerosol generating device 1 for inserting or discarding the substrate 103. The aerosol-generation chamber 33 is oriented vertically within the body, i.e., disposed along the lateral direction of the device 1. In this embodiment, there is also an intermediate position between the closed and open positions. When the cover 102 is slid to the intermediate position, the opening of the aerosol-generation chamber 103 is fully exposed. In a preferred embodiment, when the cover 102 is slid from the closed position to the intermediate position, the cover 102 simply exposes the entire opening of the aerosol-generation chamber 103.

[0023] A schematic perspective view of an aerosol-generating substrate 2 is shown in FIG. 1. The substrate 2 may include, for example, nicotine or tobacco and an aerosol-forming agent. The tobacco may take various forms, such as cut tobacco, granulated tobacco, leaf tobacco, and / or reconstituted tobacco. Suitable aerosol-forming agents include polyols (such as sorbitol, glycerol, and glycols such as propylene glycol or triethylene glycol), non-polyols (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. The substrate 103 may also include at least one of a gelling agent, a binder, a stabilizer, and a humectant.

[0024] The substrate 2 is porous to allow air to flow through it and collect the aerosol. The substrate 2 can be, for example, a foam or compressed strands or fibers. The substrate 2 can be formed into a stable shape by extrusion and / or rolling processes. The aerosol-generating substrate 2 can be shaped to have a single air passage on one side, or in a preferred embodiment, multiple air passages, more preferably on both sides, as shown in FIG. 1. These can be aligned with the air passages of the aerosol-generating device 1 to increase the air flow through the aerosol-generating chamber 103. The substrate 103 has a bare, exposed outer surface. Alternatively, the substrate 103 can include a breathable wrapper covering at least a portion of the surface of the substrate 103. The wrapper can include, for example, paper and / or a nonwoven fabric.

[0025] In this embodiment, the substrate may have a substantially flat rectangular parallelepiped or sheath shape measuring 18 x 12 x 1.2 mm, and the length, width, and depth of the rectangular parallelepiped may each be selected within a range of, for example, ±40%. Generally, in preferred embodiments, the length of the substrate 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. In preferred embodiments, the width of the substrate 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. In preferred embodiments, the depth of the substrate 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.

[0026] The aerosol-generating substrate is preferably designed to have a length equal to or less than the length of the aerosol-generation chamber 103 in the longitudinal direction 21 so that the substrate is completely covered by the cover 102 and completely enclosed and contained within the aerosol-generation chamber 103 when the cover 102 is in the closed position. In other words, the aerosol-generation chamber 107 has a substantially rectangular parallelepiped shape corresponding to the shape of the substrate 103, with dimensions of, for example, 20 x 12 x 1.2 mm, and the length, width, and depth of the rectangular parallelepiped are each selected within a range of ±40%. The length of the aerosol-generation chamber is preferably greater than the length of the substrate 2 (here, 18 mm), and the width and depth of the aerosol-generation chamber 107 are preferably greater than the width and depth of the substrate 2, which are 12 mm and 1.2 mm, respectively. More specifically, the length of the aerosol-generation chamber in a preferred embodiment 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. In a preferred embodiment, the width of the chamber 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. In a preferred embodiment, the depth of the chamber 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.

[0027] The rectangular parallelepiped of the aerosol-generation chamber has two openings on two opposite ends that form two surfaces perpendicular to the lateral direction. One of the openings (the "first opening") is configured to be an opening for inserting and discarding the substrate 2 and can be covered by a cover 102.

[0028] 2 , the main body further includes an ejection mechanism 101 (shown darkened), a LiPo battery 106, a PCBA 104 including a controller or CPU, and a USB-C connector 1063 for charging the LiPo battery 1061 and / or transmitting data to the device 1. The ejection mechanism 101 is configured to eject the substrate 2 out of the aerosol generation chamber 103 by supporting the substrate 2 through the second opening of the aerosol generation chamber 103. The aerosol generation chamber 103 is engaged with the ejection mechanism. This means that when the substrate 2 is ejected by the ejection mechanism, at least a portion of the substrate 2 can automatically protrude out of the first opening of the aerosol generation chamber, allowing the user to manually remove the substrate 2 after opening the cover.

[0029] Before using the device 1 to consume the substrate 2, the user first opens the cover 102 of the device 1 by sliding it longitudinally to an intermediate or open position. The user then inserts the substrate 103 into the first opening of the aerosol-generation chamber 103 along the insertion direction 21. The user then closes the cover 102 by sliding it to the closed position 31. The user then turns on the device using a button on the device 1 and begins consuming the substrate 2. In an alternative embodiment, a sensor may be disposed within the device 1 to detect the closure of the cover and / or the presence or absence of the substrate 2 within the device 1, which then automatically triggers heating of the substrate 2. After the user has finished consuming the substrate 2, the user simply opens the cover 2 until it is slid to the open position 33. At least a portion of the substrate 2 lifts up and automatically protrudes from the first opening of the aerosol-generation chamber 103. In a preferred embodiment, a sensor is configured to sense when the cover 102 has been opened so as to stop heating the aerosol-generation chamber 103. Finally, the user discards the substrate 2 from the device 1.

[0030] A specific configuration of the discharge mechanism 101 is shown in FIGS. 3a to 3c.

[0031] The ejection mechanism 101 is at least indirectly connected to the aerosol-generation chamber 103 and the cover 102 and at least partially engages with the cover 102. The ejection mechanism 101 includes a lever 1011 resembling or shaped like a seesaw. The lever 1011 has two straight beams or rods that pivot around a fixed hinge in the device 1. The two beams are integrated into one piece and form a fixed angle. The upper end of one of the two beams protrudes into the aerosol-generation chamber 103, and is configured to support the substrate 2 as the bottom (inner lower surface or floor) of the aerosol-generation chamber 103 while the substrate 2 is being heated. Thus, when the cover 102 is slid open, at least a portion of the substrate 2 is ejected out of the first opening of the aerosol-generation chamber 103. The lever action of the lever 1011 is triggered by the cover 102 and can be divided into two states: an ejection state and a non-ejection state. In the ejection state, the substrate 2 protrudes from the aerosol-generation chamber 103, and in the non-ejection state, the substrate 2 is completely contained by the aerosol-generation chamber 103. The ejection mechanism 101 transitions from the non-ejection state to the ejection state when the cover 102 moves from the closed position 31 to the open position 33, thereby ejecting the substrate 2 by rotating the lever 1011. More specifically, when the cover 102 slides from the closed position 31 to the intermediate position 32, the lever 1011 does not rotate, and when the cover 102 slides from the intermediate position 32 to the open position 33, the lever 1011 ejects the substrate 2 by lever action.

[0032] The ejection mechanism further includes a slide track 1013, in which a slide block 1012 is positioned and configured to engage with the cover and lever 1011 to trigger lever movement of the lever 1011. The slide track 1013 is positioned along the lateral direction of the device 1, and the slide block 1012 moves along the same axis. Along that axis, the slide block has two opposing ends. The first end has an inclined plane, and at least a portion of the second end forms an arc. The cover 102 includes a protrusion having an inclined plane that slidingly engages and cooperates with the inclined surface of the slide block 1012 between the intermediate position 32 and the closed position 33. In other words, when the cover moves from the intermediate position 32 to the closed position 33, the inclined surface of the protrusion of the cover 102 pushes the slide block 1012 so that the slide block 1012 moves downward, and the arc of the slide block 1012 pushes down one beam of the lever 1011, and the other beam of the lever 1011 is lifted by the lever action.

[0033] In a preferred embodiment, at least a portion of the ejection mechanism includes or is preferably made of a metal material, with the protrusion 1021 of the cover 102 and / or the inclined surface of the slide block 1012 preferably being made of metal.

[0034] In another preferred embodiment, a locking mechanism (not shown) is configured to mechanically engage the lever 1011 with the arc of the slide block 1012 so that the lever 1011 rotates as the slide block 1012 slides, and vice versa. More specifically, in one embodiment, a spring may be disposed under the beam of the lever 1011. In another embodiment, a ring may be disposed on the slide block 1012, with the beam of the lever 1011 extending through the ring. In yet another embodiment, magnets may be disposed in the lever 1011 and the slide block 1012. With this locking mechanism, the beam of the lever rotates and moves together with the slide block 1012 and the cover 102. Thus, the substrate 2 is automatically inserted into the heating chamber 103 from the closed position 33 to the intermediate position 32 by the beam of the lever 1011 supporting the substrate 2 rotating downward.

[0035] In other embodiments, device 1 may not be configured with a fixation device. A user can insert substrate 2 into aerosol-generation chamber 102 when cover 102 is in open position 33. As the beam of lever 1011 near the heating chamber is lifted and protrudes into aerosol-generation chamber 102, substrate 2 also protrudes at least partially outside aerosol-generation chamber 102. When the cover slides from intermediate position 32 to closed position 31, the user simply holds device 1 horizontally so that the weight of substrate 2 causes the lever to return to its original position due to gravity.

[0036] Hereinafter, the processes performed by the ejection mechanism 101 in the device 1 and the different states of the ejection mechanism 101, more specifically the ejecting and non-ejecting states, will be considered with reference to Figures 3a to 3c.

[0037] [Non-ejected state] 3a and 3b, the ejection mechanism 101 is in a non-ejecting state. The substrate 2 is fully inserted into the aerosol-generation chamber 103. One beam of the lever 1011 supporting the substrate 2 is pushed down by the substrate, and the other beam of the lever 1011 is raised together with the slide block 1012.

[0038] The ejection device remains in a non-ejecting state when the user slides the cover vertically from the closed position 31 to the intermediate position 32. The distance L1 between the protruding portion of the cover 102 and the edge of the cover covering the aerosol-generation chamber 103 is configured to be greater than the width of the aerosol-generation chamber 103. In this configuration, when the cover is slid to the intermediate position 32, the lever 1011 begins to rotate and pivot about a fixed hinge or about a lever point within the device so that the substrate 2 and the first opening of the aerosol-generation chamber 103 are fully exposed during the transition from the non-ejecting state to the ejecting state.

[0039] [Ejection status] 3c shows the ejection state of the ejection mechanism 101. The cover has been slid to the open position 33. A stop structure (not shown) is arranged within the device 1 to prevent the cover 102 from sliding further rearward. A fixing structure (not shown) may also be arranged within the device 1 to make the cover 102 bi-stable, i.e., to enable the cover 102 to stably maintain either the open or closed position. The fixing structure may consist of a central spring or magnet. The sliding block 1012 is pushed by the trapezoidal protrusion of the cover 102 and slides downward.

[0040] The beam of lever 1011 that is connected to slide block 1012 is pushed down, and the other beam of lever 1011 is raised and protrudes into aerosol-generation chamber 103. Substrate 2 is supported and protrudes from the aerosol-generation device, allowing the user to discard substrate 2 outside the device.
