Definitions

  • the present invention relates to a cartomizer for an aerosol generating device, in particular an electronic cigarette or vaporizer, with a leakage prevention system, in particular a double leakage chamber arrangement.
  • Aerosol generating devices such as electronic cigarettes or "e-cigarettes” as they are also known, have gained in popularity over the past ten years as an alternative to traditional smoking articles, like cigarettes, cigars, and cigarillos. Developments in the design and configuration of such aerosol generating devices or vaporizer devices are ongoing to improve their performance and their reliability, as well as their ease of production and their production costs.
  • Conventional aerosol generating devices usually include a heater powered by an electrical power source and a liquid reservoir containing flavoured liquid (vaporizable material) that can be volatized using the heater and transferred to a user of the aerosol generating device in an airflow, which is preferably guided through a mouthpiece of the device.
  • the heating element is often provided within the capsule, thereby forming a so called “cartomizer".
  • the heating element is provided with the cartomizer, it is each time the cartomizer (capsule) is replaced, hence, there is no reduction in performance over time.
  • a liquid transport element in particular a wick
  • a coil that is wound around the wick
  • measures should be put in place that contain leaked vaporizable material within the capsule, should leakage occur. Therefore, it is desirable to provide a cartomizer with means that can prevent leaking vaporizable material to affect either the device or consumer.
  • US 9,737,093 B2 is related to an electronic cigarette comprising from a first, vaping end and a second end distal from the user's mouth, a cartridge, a vaporizer and a battery. It is further disclosed to provide a circular chamber that has direct access to the vaporizing chamber in order to collect leaking vaporizable material. A similar device is shown in US 2019/0335813 A1 .
  • a cartomizer for an aerosol generating device in particular an electronic cigarette or vaporizer, capable of preventing leakage of vaporizable material or liquid from the heater or the liquid transport element (wick) to the outside of the cartomizer, in particular via an air inlet of the cartomizer, thereby ensuring that leaked vaporizable material or liquid affects either the device or consumer.
  • a cartomizer for an aerosol generating device in particular an electronic cigarette or vaporizer
  • the cartomizer including: a container for holding at least one reservoir configured to contain a vaporizable material, a vaporizing chamber fluidly connected to a mouth end by a vapor passage, a liquid transport element, in particular a porous capillary member, extending from inside the at least one reservoir to the inside of the vaporizing chamber in order to convey or wick or otherwise transport the vaporizable material from the at least one reservoir to the inside of the vaporizing chamber and an air inlet arranged to supply the vaporizing chamber with air in use, wherein a leakage collecting chamber is arranged, in particular in an airflow direction from the air inlet to the vaporizing chamber, between the vaporizing chamber and the air inlet to collect vaporizable material (leaking) from the vaporizing chamber, and the leakage collecting chamber includes at least one liquid stopping or barrier wall, in particular a first liquid stopping
  • a cartomizer for an aerosol generating device capable of reducing the likelihood that vaporizable material or liquid, leaking from the liquid transport element or a heater of the cartomizer reaches the outside of the cartomizer via the air inlet. Thereby, ensuring that leaked vaporizable material or liquid is prevented from affecting the device or a user of the device.
  • the air inlet may comprise or may be formed by an air conduit or chimney that is arranged at the bottom of the container and upstream the through-hole of the air inlet, wherein the air conduit or chimney, in particular a sidewall thereof, forms a second liquid stopping or barrier wall that is arranged between the first liquid stopping or barrier wall and the at least one through-hole.
  • the air conduit or chimney may protrude inside the leakage collecting chamber.
  • the cartomizer may further include a center leakage collecting chamber that is provided between the air inlet and the leakage collecting chamber, in particular in an airflow direction from the air inlet to the vaporizing chamber, wherein the center leakage collecting chamber is preferably defined or formed by the air conduit or chimney and the first liquid stopping or barrier wall.
  • the center leakage collecting chamber and the leakage collecting chamber or the leakage collecting chambers are at least partially separated from each other by the first liquid stopping or barrier wall including at least one connecting hole or groove (fluidly) connecting the center leakage collecting chamber with the leakage collecting chamber or chambers, wherein the connecting hole or groove is preferably arranged with a predetermined axial distance to the bottom of the container.

  • the "axial direction of the cartomizer” defines in the present application in general a longitudinal direction of the cartomizer.
  • the "axial direction of the cartomizer” also refers to a direction in which the air flows in general through the cartomizer, namely from the air inlet of the cartomizer to the mouth end of the cartomizer, which is configured to come into contact with the lips of a user during use of the aerosol generating device.
  • the air outlet of the leakage collecting chamber may be transversally distant from the air inlet.
  • the air outlet might be arranged with a predetermined distance to the air inlet when seen in a plane perpendicular to the axial direction of the cartomizer. Therefore, in use, liquid entering the leakage collecting chamber through the air outlet has no straight path to the air inlet and becomes collected in the collecting chamber instead.

  • the leakage collecting chamber may include two air outlets communicating with the vaporizing chamber and arranged on each side of the air inlet.

  • the first seal may include air channels that fluidly connect the center leakage collecting chamber with the leakage collecting chamber or the leakage collecting chambers.
  • the container, shell or outside casing of the cartomizer may be formed of a rigid material, in particular a rigid thermoplastic material, glass or metal.
  • Aerosol generating devices use electrical energy to heat a material (preferably without combusting the material to any significant degree and/or without significant chemical alteration of the material) to form an inhalable substance or vapor; and components of such device have the form of articles that most preferably are sufficiently compact to be considered hand-held devices.
  • use of components of preferred aerosol generating devices does not result in the production of smoke in the sense that aerosol results principally from by-products of combustion or pyrolysis of tobacco, but rather, use of those devices preferably results in the production of vapors resulting from volatilization or vaporization of certain components incorporated therein.
  • components of aerosol generating devices may be characterized as electronic cigarettes, and those electronic cigarettes preferably incorporate aerosolisable liquid (e.g. propylene glycol, polyhydric alcohol), tobacco and/or tobacco materials derived at least partially from tobacco, and hence deliver tobacco derived components in aerosol or vapor form to a user.
  • aerosol generating devices within the meaning of the present invention may transport the volatilized particles in an airflow through the aerosol generating device, in particular through the cartomizer, to a user of the device, the user of the device being able to activate or deactivate the generation of aerosol and to control the duration, velocity and volume of the airflow by means of puffing or inhaling action.
