  • a “smokable article” is an article or component that includes or contains in use the smokable material which in use is heated to volatilize.
  • An aerosol generation apparatus that heats smokable material to vaporize at least one component of the smokable material, typically to form an aerosol which can be inhaled, without burning or combusting the smokable material.
  • Such apparatus is sometimes described as a “heat-not-burn” apparatus or a “tobacco heating product” or “tobacco heating device” or similar.
  • e-cigarette devices which typically vaporize a smokable material in the form of a liquid.
  • the smokable material may be in the form of or provided as part of a rod, cartridge, or cassette or the like which can be inserted into the apparatus.
  • a heater for heating and vaporizing the smokable material may be provided as a "permanent" part of the apparatus.
  • FIG 1A contains a schematic illustration of a cross-sectional view of an example apparatus 100 arranged to heat smokable article 101 to volatilize one vaporizable material of the smokable material 101.
  • the apparatus 100 comprises a housing 102, which has a first inlet 103 at a first end through which the smokable article 101 can pass so as to be received within and removed from the apparatus 100 in use.
  • the smokable article 101 is provided as part of a rod, which can be inserted into the apparatus 100. The insertion is for example operated by a user of the apparatus 100 who holds the rod with his/her fingers and introduces the rod into the first inlet 103.
  • the housing 102 further has a second inlet 104 distant from the first end.
  • the second inlet 104 is located at a side of the apparatus 100 which is opposite to the side on which the first inlet 103 is located.
  • the second inlet 104 may be configured to allow air to be supplied to the apparatus.
  • the housing 102 further has a chamber 105 between the first and second inlets 103 and 104.
  • the chamber 105 may be considered a cavity construction of its own mounted inside the housing 102. As illustrated in the example of figure 1A, the chamber 105 may be aligned longitudinally between the first and second inlets 103 and 104 of the housing 102.
  • the first inlet 103 may be associated to a closure (not illustrated) which can be opened before insertion of the smokable article in the chamber.
  • a closure of the second inlet 104 may be designed to provide an opening of adjustable size and/or may obturate fully the opening in a closed position.
  • the apparatus 100 further comprises at least one heater 106 arranged within the housing 102 for heating the smokable article 101 removably received within the chamber 105 in use.
  • the heater 106 may be configured to surround the chamber 105, i.e. , in case the chamber 105 is shaped as a longitudinally extending cylinder, the heater 106 may have the shape ora ring placed around a portion of an external wall of the chamber’s 106 cylinder.
  • the heater may comprise a thin film heater or a ceramic heater. In a possible mode, the heater may form part or parts of the wall of the chamber.
  • the smokable article 101 and/or the rod which contains the smokable article 101 are not considered to be part of the apparatus 100, but remain objects which can be introduced into the apparatus 100 for consumption by the user, and subsequently removed from the apparatus 100, the introduction and the removing being done in a direction of a double arrow A shown in figure 1 A.
  • the apparatus 100 further comprises a stopping device 107 located inside the chamber 105 towards or next to the second inlet 104.
  • the distance from the stopping device 107 to the second inlet 104 is smaller than the distance from the first inlet 103.
  • the stopping device 107 is configured to stop in a predetermined heating position the smokable article 101 passed through the first inlet 103 in use. Indeed, at a time the rod of smokable article 101 is introduced into the first inlet 103, in direction of the double arrow A, it first penetrates into the housing 102, and subsequently penetrated the chamber 105 until it collides with the stopping device 107.
  • the stopping device 107 has no effect on sizes of the second opening surface area 109 and the third opening surface area 110, nor does it affect for example a size of the second inlet 104 of the housing, and thus is does not affect any throughput capacity for gases flowing as a result of vaporizing materials from the smokable article 101.
  • the first opening surface area 108 is smaller than a surface of the smokable article 101 presented towards it at the time of introducing the smokable article 101 into the first inlet 103.
  • the heater 106 may be arranged to heat the chamber 105, either only along a portion of its length or along its entire length.
  • the housing 102 further comprises, as schematically represented in a box 111 , further components, comprising at least a control circuitry and a power source (not individually represented in figure 1A), connected to the heater 106 as appropriate.
  • the control circuitry may include a controller, such as a microprocessor arrangement, configured and arranged to control the heating of the smokable material.
  • the power source may be for example a battery, which may be a rechargeable battery or a non-rechargeable battery. Examples of suitable batteries include for example a lithium-ion battery, a nickel battery (such as a nickel-cadmium battery), an alkaline battery and/ or the like.
  • the battery is electrically coupled to the heater 106 to supply electrical power when required and under control of the control circuitry to heat the smokable article 101 and so vaporize the smokable material.
  • the rod 300 is of cylindrical shape, hence the stopping device 107 is disk-shaped.
  • This preferred embodiment is shown as a schematic illustration of a cross section of an example embodiment of the rod 300 according to axis A-A in figure 3, in which, incidentally, the chamber 105 also has a cylindrically shaped wall.
  • the diameter of the smoking article 101 is represented as a circle in dotted line.

Abstract

Appareil de production d'aérosol comprenant un boîtier ; le boîtier comporte une première entrée au niveau d'une première extrémité, à travers laquelle un article à fumer peut passer afin d'être reçu à l'intérieur de l'appareil et retiré de ce dernier lors de l'utilisation ; le boîtier comporte une seconde entrée éloignée de la première entrée ; le boîtier comporte une chambre entre la première entrée et la seconde entrée ; et au moins un élément chauffant est agencé à l'intérieur du boîtier afin de chauffer l'article à fumer reçu amovible à l'intérieur de la chambre lors de l'utilisation. L'appareil comprend en outre un dispositif d'arrêt situé à l'intérieur de la chambre vers la seconde entrée, le dispositif d'arrêt étant conçu pour arrêter, dans une position de chauffage prédéfinie, l'article à fumer ayant passé à travers la première entrée lors de l'utilisation ; et le dispositif d'arrêt est conçu en outre de sorte qu'une première surface d'ouverture de la chambre, au niveau du dispositif d'arrêt, soit plus petite qu'une deuxième surface d'ouverture de la chambre en amont du dispositif d'arrêt, et que la première surface d'ouverture de la chambre, au niveau du dispositif d'arrêt, soit plus petite qu'une troisième surface d'ouverture de la chambre en aval du dispositif d'arrêt ; ou bien le dispositif d'arrêt comprend une surface d'extrémité d'une tige positionnée le long d'un axe longitudinal central de la chambre, et un passage d'écoulement est présent entre la tige et la chambre.
