Definitions

  • the present disclosure relates to an aerosol generation device in which an aerosol generating substrate is heated to form an aerosol; more specifically, to an aerosol generation device with an ejection mechanism using leverage.
  • aerosol generation devices also known as heat-not-burn products or vaporizers or E-cigarette
  • 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.
  • 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.
  • 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.
  • 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:
  • 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.
  • 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.
  • 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.
  • the substrate is only ejected when the aerosol generation chamber is fully exposed, which avoids incidental operation by the user.
  • the lever at least partially defines the bottom surface of the aerosol generation chamber.
  • 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.
  • 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.
  • 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.
  • the protrusion (1021) of the cover and/or the protrusion of the sliding block are made of metal.
  • the aerosol generation device has an elongated shape, and the cover is arranged to slide in a longitudinal direction of the aerosol generation device.
  • aerosol generation device may include an electronic cigarette configured to deliver an aerosol to a user, including an aerosol for smoking.
  • aerosol generation system in this invention are schematic.
  • the electronic cigarette 1 for consuming a substrate is illustrated.
  • the electronic cigarette 1 can be used as a substitute for a conventional cigarette.
  • the electronic cigarette 1 has a substantially elongated shape comprising a cover 102, and a main body 106.
  • the cover 102 is slidingly engaged with the main body 106 via a slide track (not shown).
  • the cover is arranged on a side surface of the main body of the device 1, and slides along the direction which is perpendicular to the insertion direction of the substrate 2.
  • the cover 102 When taking the direction parallel to the insertion direction 21 as the transverse direction, and the direction perpendicular to the insertion direction 21 as the longitudinal direction, the cover 102 is arranged to slide in a longitudinal direction of the aerosol generation device 1.
  • the cover 102 has a closed position 31 covering the aerosol generation chamber 103 when the user consumes the substrate 103 and an open position 33 exposing the opening of the aerosol generation chamber 103 comprised by the aerosol generation device 1 for inserting or discarding the substrate 103.
  • the aerosol generation chamber 33 is vertically orientated in the main body, namely arranged along the transverse direction of the device 1. In the present embodiment, there is also an intermediate position between the closed position and the open position.
  • the cover 102 When the cover 102 is slid to the intermediate position, the opening of the aerosol generation chamber 103 is completely exposed. In a preferred embodiment, when the cover 102 is slid from the closed position to the intermediate position, the cover 102 just reveals the complete opening of the aerosol generation chamber 103.
  • the substrate 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.

These can be aligned with the air flow channel of the aerosol generating device 1 in order to increase air flow through the aerosol generation chamber 103.
  • the substrate 103 is exposed with a bare external surface.
  • the substrate 103 may comprise an air permeable wrapper covering at least part of a surface of the substrate 103.
  • the wrapper may, for example, comprise paper and/or non-woven fabric.

This means that at least a portion of the substrate 2 can stick out of the first opening of the aerosol generation chamber automatically when the substrate 2 is ejected by the ejection mechanism, and the substrate 2 can be taken out by the hand of the user after the cover is opened.
  • the user Before using the device 1 and consuming the substrate 2, the user first opens the cover 102 of the device 1 by sliding the cover 102 along the longitudinal direction till the intermediate position or the 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 substrate 2 is ejected out of the first opening of the aerosol generation chamber 103 when the cover 102 is slidingly opened.
  • the leverage movement of the lever 1011 is triggered by the cover 102 and can be separated into two states: an ejected state and a non-ejected state.
  • the substrate 2 protrudes from the aerosol generation chamber 103, and in the non-ejected state, the substrate 2 is fully contained by the aerosol generation chamber 103.
  • the ejection mechanism 101 transitions from the non-ejected state to the ejected state when the cover 102 is moved from the closed position 31 to the open position 33, thereby ejecting the substrate 2 by rotating the lever 1011.
  • the lever 1011 does not rotate when the cover 102 is slid from the closed position 31 to the intermediate position 32, and the lever 1011 ejects the substrate 2 by the leverage movement when the cover 102 is slid from the intermediate position 32 to the open position 33.

  • a ring may be configured on the sliding block 1012 through which the beam of the lever 1011 extends.
  • magnets may be arranged in the lever 1011 and the sliding block 1012. Having this fixation mechanism, the beam of the lever rotates and moves together with the sliding block 1012 and the cover 102.
