Definitions

  • the present disclosure relates to elements for an aerosol generating system and for producing an aerosol or vapor for inhalation by a user.
  • the present disclosure relates more particularly to an aerosol generating system with a conically shaped heating element and a corresponding vaporizable material capsule cartridge for holding a vaporizable material substance for producing an aerosol or vapor.
  • aerosol generating systems also known as e-cigarettes, e-cigs (EC), electronic nicotine delivery systems (ENDS), electronic non-nicotine delivery systems (ENNDS), electronic smoking devices (ESDs), personal vaporizers (PV), inhalation devices, vapes, which can be used as an alternative to conventional smoking articles such as lit-end cigarettes, cigars, and pipes, is becoming increasingly popular and widespread.
  • e-cigarettes are usually battery powered and use a resistance heating element to heat and atomize a liquid containing nicotine and/or flavorants (also known as e-cigarette liquid, e-cig liquids, e-liquid, juice, vapor juice, smoke juice, e-juice, e-fluid, vape oil), to produce an aerosol (often called vapor) which can be inhaled by a user.
  • nicotine and/or flavorants also known as e-cigarette liquid, e-cig liquids, e-liquid, juice, vapor juice, smoke juice, e-juice, e-fluid, vape oil
  • the liquid is put into contact with a resistance heating element after flowing through small channels, where it is heated and vaporized.
  • the flowing is realized for example via a wick, a mesh or another type of porous element, which has a plurality of small channels that transport the liquid from a reservoir to the heating element.
  • This heating element together with the porous element, a reservoir that contains the vaporizable material, and a mouthpiece are usually arranged within a disposable capsule, cartridge or pod, that is discarded or refilled once the vaporizable material has been consumed by the user, and usually removably connects to a main body that includes a rechargeable battery.

  • the at least one airflow channel groove is configured to collect and receive vaporized vaporizable material, i.e., vaporizable material which is heated and hence aerosolized by the conically shaped heating element 101, and directs the aerosolized vaporizable material through a vapor conduit 107, which in turn enables the aerosol to reach an aerosol delivery port such as a mouthpiece, to be inhaled by an intended user (mouthpiece and user not represented in FIG. 1 ).

  • the fresh air grooves 200 enable fresh air to be provided and hence the airflow process may be sustained.
  • the configuration according to the invention enables an efficient airflow management by means of a configuration of grooves and heating zones that are distributed all around the circumference of the conically shaped heating element, whereby grooves are exclusively comprised in the conically shaped heating element in the specific example embodiment illustrated in FIG. 2 . Further examples will be explained in the following paragraphs.

  • Further all fresh air grooves 200 and airflow channel grooves 201 are to be comprised on the side of the concave slanted surface, i.e., on the side of the vaporizable material capsule.
  • the manner in which the airflow is managed in this further example embodiment is somewhat similar to the airflow management in FIG. 2 explained in the preceding paragraph, and this offers similar advantages.
  • the main difference is that the grooves need to be manufactured into the vaporizable material capsule.
  • FIG. 3 illustrates yet another example embodiment according to the invention, which illustrates a top-view of a section through the conically shaped heating element 101, including for a better understanding also a representation of the location of the cone top (the smaller circle in the middle).
  • the illustration shows a circumference of the conically shaped heating element 101 delimited by the convex slanted surface 104 and a circumference of the vaporizable material capsule delimited by the concave slanted surface 105, and the layer of wicking element 106 in between.
  • the heating zones 203 are comprised on the side of the conically shaped heating element 101, together with the airflow channel grooves 201, while the fresh air grooves 200 are comprised on the side of the vaporizable material capsule.
  • the conically shaped cavity of the vaporizable material capsule is delimited at its opening by an opening circumference that has the larger diameter, and at the other end of the cone by a bottom.
  • the fresh air grooves 200 extend between the opening circumference and the bottom.
  • FIG. 3 may be used to discuss a further example embodiment, although this is not explicitly illustrated.
  • the airflow channel grooves are replaced by fresh air grooves, and vice-versa.
  • FIG. 4 illustrates yet another example embodiment according to the invention, which, similar to FIG. 3 illustrates a top view of a section through the conically shaped heating element 101.
  • a part of the wall 400 from the vaporizable material capsule, delimited by concave slanted surface 105 is represented.
  • the heating zones 203 are comprised on the side of the conically shaped heating element 101, together with airflow channel grooves 201, while the fresh air grooves 200 are comprised on the side of the vaporizable material capsule. All grooves and heating zones together form a plurality of groups comprising in this order: one airflow channel groove 201, one heating zone 203. Each of the groups further comprises one fresh air channel 200 which is arranged opposite of the heating zone 203.
  • the illustration in FIG. 4 comprises three such groups.
  • FIG. 4 may be used to discuss a further example embodiment, although this is not explicitly illustrated. In this further example embodiment, it should be considered that the airflow channel grooves are replaced by fresh air grooves, and vice-versa.
  • the layer of wicking element 106 has an opening respectively located between each heating zone 203 and each fresh air groove 200. This may improve the efficiency of the airflow from the fresh air groove 200 to each of the surrounding airflow channel grooves 201, as the portion of wicking element 106 that the air travels through the wicking element to flow from one groove to another groove is shorter than if the wicking element had covered the whole heating zone 203 along the circumference. However, it may be desirable to actually extend the wicking element 106 over the heating element in order to adjust a resistance to air flow from one groove to another, and this may be part of a further preferred embodiment that is not illustrated in the figures.
  • FIG. 5 shows yet another example embodiment of a conically shaped heater element in a sectional top-view, the viewing angle being similar as that from FIG. 3 and FIG. 4 .
  • the heating zones 203 are comprised on the circumference of the heating element 101, and the whole circumference is covered by a layer of wicking element 106.
  • FIG. 6 illustrates the conically shaped heating element of FIG. 5 as inserted in the cavity of a vaporizable material capsule 102, whereby the layer of wicking element is covered up by part of the vaporizable material capsule's wall.
  • the fresh air grooves 200 and the airflow channel grooves 201 are comprised in the vaporizable material capsule 102.
  • All grooves and heating zones together form a plurality of groups comprising in this order: one airflow channel groove 201, one heating zone 203.
  • Each of the groups further comprises one fresh air channel 200 which is arranged opposite of the heating zone 203.
  • the illustration in FIG. 6 comprises three such groups.
  • An advantage of the example embodiment illustrated in FIG. 6 is that all the grooves are part of the vaporizable material capsule 102, which typically may be a disposable part of the aerosol generating system. Hence, they are renewed at each change of the vaporizable material capsule, and are always comparatively clean, as compared to grooves located on the side of the conically shaped heating element, which have a longer life cycle and hence run a greater probability of becoming clogged over time.
  • a further advantage of the present invention is that holding the liquid in a separate portion than the gap has the advantage to not continuously heat up the whole reservoir that may not be good for the taste of the generated aerosol.
  • a further advantage of the present invention is that the porous layer is localized inside the cone, that is easier and more efficient as liquid will remain in the porous area.
  • a further advantage is that having grooves on the slanted surface of the conically shaped heating element allows to optimize the vapor/airflow path volume compare to prior art with limited airflow/vapor capability due to space restriction.
