Definitions

  • the openings 23 are substantially circular shaped openings. In other examples, the openings 23 may have a different shape.
  • the axial length of the inductively heatable susceptor 18 is less than the axial length of the outer surface 24 of the liquid transfer element 20.
  • the term “axial length” means a length in the direction of the longitudinal axis of the cartridge 10.
  • the inductively heatable susceptor 18 may have an axial length of from 0.5 mm to 15 mm. At the lower end of this range, the inductively heatable susceptor 18 may comprise susceptor rings. In some examples, the inductively heatable susceptor 18 may have an axial length of from 3 mm to 5 mm. In the illustrated example, the inductively heatable susceptor 18 has an axial length of about 4 mm.
  • An inductively heatable susceptor 18 having these axial length dimensions may further optimise the balance between the quantity of vapour generated and the time (and thus energy) required to generate the vapour, thus further improving performance.
  • the cup 32 may comprise a heat resistant material.
  • the cup 32 may comprise a plastics material, such as polyether ether ketone (PEEK), ceramic or glass.
  • PEEK polyether ether ketone
  • the cup 32 may be a glass tube.
  • the cup 32 is configured to ensure airflow is directed into a vaporisation chamber 40 defined by the liquid transfer element 20, further improving vapour generation and energy efficiency.
  • the cup base 29 prevents linear airflow away from the vaporisation chamber 40.
  • the cup 32 also prevents undesirable vapour leakage. Furthermore, this arrangement improves airflow over the inductively heatable susceptor 18, further improving vapour generation and energy efficiency.
  • the vapour escapes from the liquid transfer element 20 into the vaporisation chamber 40, and then flows from the vaporisation chamber 40 along the vapour outlet channel 46 where it cools and condenses to form an aerosol that is inhaled by a user through the mouthpiece 44.
  • the vaporisation of the vapour generating liquid is facilitated by the addition of air flowing from the surrounding environment through the one or more air inlets 33 into the interior 30 of the cup 32. Air flows from the interior 30 of the cup 32 into the vaporisation chamber 40 via the airflow path defined by the at least one indentation 42 comprised in the base 38 of the liquid transfer element 20.
  • Vapour generated is entrained in the air as it flows from the interior 30 of the cup 32 into the vaporisation chamber 40 and along the vapour outlet channel 46 to the mouthpiece 44.

Abstract

L'invention concerne une cartouche (10) pour un dispositif de génération de vapeur (100). La cartouche (10) comprend un réservoir de liquide (12) destiné à contenir un liquide de génération de vapeur et une unité de génération de vapeur (13). L'unité de génération de vapeur (13) comprend un dispositif de vaporisation (14). Le dispositif de vaporisation (14) comprend un élément chauffant (16) comprenant un suscepteur (18) pouvant être chauffé par induction. L'unité de génération de vapeur (13) comprend en outre un élément de transfert de liquide (20) agencé pour maintenir et transférer le liquide de génération de vapeur du réservoir de liquide (12) au dispositif de vaporisation (14) par action capillaire. Le suscepteur (18) pouvant être chauffé par induction est disposé à proximité thermique de l'élément de transfert de liquide (20) pour chauffer et vaporiser le liquide de génération de vapeur maintenu et transféré au dispositif de vaporisation (14) par l'élément de transfert de liquide (20). Le suscepteur (18) pouvant être chauffé par induction entoure l'élément de transfert de liquide (20) et présente une surface intérieure (22) qui entre en contact avec une surface extérieure (24) de l'élément de transfert de liquide (20). Le suscepteur (18) pouvant être chauffé par induction possède un diamètre intérieur de 3 mm à 10 mm. L'élément de transfert de liquide (20) possède un diamètre extérieur correspondant au diamètre intérieur du suscepteur (18) pouvant être chauffé par induction.
