Definitions

  • Aerosol-generating systems comprise either a cartridge including liquid aerosolforming substrate or an aerosol-generating article including solid aerosol-forming substrate. These products can be consumed as heat-not-burn products and often contain flavorings which cannot be changed while the cartridge is in use. Cartridges often cannot be disconnected from their respective aerosol-generating devices without the risk of leakages or breaking the cartridge. Any flavorings present in the liquid aerosol-forming substrates of cartridges may have a short shelf life, mainly due to the chemically reactive nicotine component. Similarly, a user may purchase a complete set of aerosol-generating articles, which all include the same flavor.
  • a mouthpiece for inhaling an aerosol may comprise an airflow channel for the aerosol extending through the mouthpiece.
  • the mouthpiece may comprise a flavor compartment comprising at least one flavoring agent for flavoring the aerosol.
  • the flavor compartment of the mouthpiece may be in fluid communication with the airflow channel in a central portion of the airflow channel. A cross-sectional area of the airflow channel in the central portion may increase in the flow direction through the airflow channel.
  • An increasing cross-sectional area of the airflow channel in the central portion in the flow direction may decrease the speed of the aerosol in flow direction when passing through the central portion of the airflow channel. This may provide a Venturi effect. This may increase the mixing of the aerosol with the at least one flavoring agent, which is in fluid communication with the central portion of the airflow channel. This also may lead to an increase in turbulent air flow through the mouthpiece, additionally aiding in the mixing of the aerosol and the at least one flavoring agent. This may also aid in the volatilization of the at least one flavoring agent. Thus, a more homogeneous mixture of the aerosol and the at least one flavoring agent may be provided to the user through the mouthpiece.
  • the mouthpiece therefore may comprise at least two or three expansion areas for the aerosol.
  • One first expansion area may be located at the upstream end of the mouthpiece at the upstream end of the airflow channel through the mouthpiece and a second expansion area may be located in the central portion of the airflow channel.
  • the cross-sectional area of the first expansion area may be smaller than the cross-sectional area of the second expansion area in the central portion of the airflow channel. This may lead to the speed of the aerosol being lower in the second expansion area in comparison to the first expansion area. This may lead to a reduction of the speed of the aerosol going from the first expansion area through the second expansion area. This may provide a Venturi effect.
  • These expansion areas may “flush” the aerosol generated from an aerosol-forming substrate towards the mouthpiece and through the central portion of the airflow channel of the mouthpiece to the downstream end of the mouthpiece to be delivered to a user.
  • the cross-sectional area of the airflow channel in the first expansion area at the upstream end of the mouthpiece may increase in the flow direction through the airflow channel.
  • the cross-sectional area of the airflow channel in the third expansion area at the downstream end of the mouthpiece may increase in the flow direction through the airflow channel.
  • the cross-sectional area of the airflow channel in the central portion, the second expansion area also may increase in the flow direction through the airflow channel. This may enable an efficient channeling of the aerosol or of the mixture of the aerosol and the at least one flavoring agent through the mouthpiece towards the user.
  • One or both of a cross-sectional area of the airflow channel between the upstream end and the central portion remains at least partly the same or a cross-sectional area of the airflow channel between the central portion and the downstream end remains at least partly the same.
  • the cross-sectional area of the airflow channel does not change between the upstream end and the central portion of the airflow channel or between the central portion of the airflow channel and the downstream end of the mouthpiece. This may enable an expansion of the aerosol or of the mixture of the aerosol and the at least one flavoring agent only in the expansion areas of the mouthpiece, where the cross-sectional area of the airflow channel changes in flow direction.
  • Opposing walls of the airflow channel in the central portion may comprise the porous material for releasing the at least one flavoring agent.
  • a distance between the opposing walls may increase in the central portion in the flow direction through the airflow channel.
  • the aerosol-generating system may comprise a mouthpiece as described herein.
  • the aerosolgenerating system furthermore may comprise a cartridge containing an aerosol-forming substrate and may comprise an aerosol-generating device.
  • the mouthpiece may be configured to be detachably connectable to the cartridge.
  • the cavity may be configured as a heating chamber.

  • the cavity may have a circular cross-section.
  • the cavity may have an elliptical or rectangular cross-section.
  • the cavity may have an inner diameter corresponding to the outer diameter of the aerosol-generating article.
  • Example B Mouthpiece according to the preceding example, wherein one or both of: - a cross-sectional area of the airflow channel at the upstream end of the mouthpiece is smaller than the cross-sectional area of the airflow channel in the central portion or
  • the cross-sectional area of the airflow channel in the central portion is smaller than a cross-sectional area of the airflow channel at the downstream end of the mouthpiece.
  • Example F Mouthpiece according to any of the preceding examples, wherein the flavor compartment comprises at least one aerosol-former, preferably wherein the at least one aerosol-former is selected from a group consisting of: propanediol, propanediol, glycerol, diacetate, diethyl phthalate.
  • Example G Mouthpiece according to any of the preceding examples, comprising a longitudinal axis, wherein the airflow channel extends along the longitudinal axis.
  • Example J Mouthpiece according to the preceding example, wherein the inlet portion is being configured for being detachably connectable to one or both of a cartridge for an aerosol-forming substrate, and an aerosol-generating device.
  • Example L Mouthpiece according to the preceding example, wherein the tubular section comprises an opening at the upstream end, preferably wherein the opening at the upstream end has a smaller cross-sectional area than the downstream end of the tubular section.
  • Example V Aerosol-generating system according to the preceding example, wherein the heater element comprises connection pins configured for being connected to an energy source of an aerosol-generating device.
  • Example X Aerosol-generating system according to the preceding example, wherein the aerosol-generating device comprises electrical connections, being configured to be connectable to the cartridge, preferably according to example V, wherein the electrical connections are configured to be detachably connectable to the connection pins of the cartridge.

  • the hollow connection portion 11 with the outer walls 10C can be put over the cartridge upon connection of the mouthpiece with the cartridge.
  • the mouthpiece 10 also includes an outlet portion 10A which is configured to provide an outflow of the mixture of the aerosol and the at least one flavoring agent to a user.
  • the mouthpiece 10 includes three different expansion areas. At the upstream end of the mouthpiece 10 a first expansion area is present, indicated by the dashed circle 15, wherein the air flow channel has a certain cross-sectional area. This is indicated by the diameter of the tubular airflow channel indicated by the double arrow 14A in Fig. 1A.
  • the flavor compartment 16 includes at least one flavoring agent 12, which preferably is a volatile flavoring agent.
  • Fig. 2 depicts a cross-sectional view of a disassembled aerosol-generating system, including a mouthpiece 10 in accordance with the present invention, a cartridge 24 and an aerosol-generating device 32.
  • the direction of assembling the aerosol-generating system is indicated by the arrows in Fig. 2.
  • the tubular portion 18 of the inlet portion 10B of the mouthpiece 10 can be inserted into the central hollow portion 24A of the cartridge 24.

  • an additional airflow channel 14D is formed. This additional airflow channel is formed through a gap between the mouthpiece 10 and the cartridge 24.
  • ambient air can enter the aerosol-generating system through the mouthpiece air inlet 20 and can be directed through a newly formed airflow channel which is formed between the inner walls of the cartridge, which are adjacent to the central hollow portion of the cartridge and between the tubular section 18 of the mouthpiece.
  • the ambient air can mix with the aerosol-forming substrate in the first expansion area to form an aerosol.
  • This aerosol is then directed through the tubular section 18 of the mouthpiece towards the second expansion area in the central portion of the airflow channel of the mouthpiece.
