Abstract
The inventionThe invention relates to a mouthpiece (10) for inhalation of an aerosol, comprising an airflow path (14) for an aerosol, the airflow path leading through the mouthpiece, wherein a flavour particle (12) is arranged in the airflow path, the flavour particle containing at least one flavour for flavouring the aerosol, and wherein the flavour particle is configured to be movable by a user's suction, wherein the flavour particle comprises a porous matrix material comprising the at least one flavour, and wherein the porous matrix material has a density between 0.4 and 2g/cm 3 Between them.
Description
Technical Field
The present invention relates to a mouthpiece for inhalation of aerosols. The invention further relates to a flavour particle for flavouring an aerosol.
Background
The aerosol-generating system comprises a cartridge comprising a liquid aerosol-forming substrate or an aerosol-generating article comprising a solid aerosol-forming substrate. These products are consumable as heated non-combustible products and typically contain flavoring that is not changeable when the cartridge is used. The cartridge is typically not disconnectable from its respective aerosol-generating device without the risk of leakage or damage to the cartridge. Due primarily to the chemically reactive nicotine component, any flavouring present in the liquid aerosol-forming substrate of the cartridge may have a short shelf life. Similarly, a user may purchase a complete set of aerosol-generating articles that all comprise the same flavor.
It is desirable to provide the user with the possibility to change the flavour of the aerosol-generating system when in use. Furthermore, it is desirable to provide the user with the possibility to change the flavouring of individual aerosol-generating articles comprised in a group of aerosol-generating articles at the convenience of the user. Furthermore, it is desirable to provide the user with the possibility to obtain different flavourings depending on the intensity of the user's suction. In addition, it is desirable to provide the user with the possibility to change the flavouring provided by the aerosol-generating system without significant energy consumption. Furthermore, it is desirable to provide means for flavoring aerosols that can provide additional flavoring to heated non-combustible products or to conventional cigarettes.
Disclosure of Invention
According to an embodiment of the present invention, a mouthpiece for inhalation of aerosols is provided. The mouthpiece may comprise an airflow path for the aerosol, wherein the airflow path may be directed through the mouthpiece. The mouthpiece may comprise flavour particles arranged in the airflow path. The flavour particles may contain at least one flavouring agent for flavouring the aerosol. The fragrance particles may be configured to be movable by suction of a user.
According to another embodiment of the present invention, a mouthpiece for inhalation of aerosols is provided. The mouthpiece includes an airflow path for the aerosol, which is directed through the mouthpiece. The mouthpiece further comprises flavour particles arranged in the airflow path. The flavour particles contain at least one flavouring agent for flavouring the aerosol. The fragrance particles are also configured to be movable by suction of a user.
The fragrance particles may move depending on the intensity of the user's suction. The fragrance particles may float in the air stream generated by the user's suction. The stronger the user draws, the more fragrance particles can move through the path. The stronger the user puffs, the more flavoring that is releasable by the floatable flavor particles in the user's puffs air stream. This may enable the user to control the flavouring of the aerosol depending on the intensity of his/her puffs.
The flavor particles may be configured to flavor the aerosol in proportion to the intensity of the user's puff.
The flavor particles can be configured to release at least one flavoring agent upon inhalation by a user. This may provide additional flavouring of the aerosol without heating the flavour particles. This may provide a simple method for flavouring an aerosol by simply drawing through the mouthpiece.
The aerosol received by the mouthpiece for further flavouring may be generated from a variety of different aerosol-forming substrates. The aerosol-forming substrate may be one or more of a liquid, gel or solid aerosol-forming substrate.
The mouthpiece may be configured to be removably connected to one or both of an aerosol-generating article or a cartridge containing an aerosol-forming substrate. The aerosol-generating article may comprise a matrix segment comprising an aerosol-forming matrix. The aerosol-forming substrate may form an aerosol upon heating or upon combustion. The flavour particles of the mouthpiece may provide additional flavour to the aerosol generated by the aerosol-forming substrate. The mouthpiece may provide the user with the opportunity to select different mouthpieces with different flavourants for the same aerosol-generating article or cartridge at the user's convenience.
The perfume particle may comprise a porous matrix material comprising at least one flavour. At least one flavoring agent may be embedded within the porous matrix material. At least one flavoring agent is absorbable by the porous matrix material.
This ensures that a significant amount of at least one flavouring agent can be included in the flavour granules. This may also ensure that a large amount of at least one flavouring agent may be released into the aerosol upon inhalation by the user. The porous matrix material ensures that the fragrance particles can be moved by the suction of the user. This may also configure the fragrance particles to float in the user's puff.
The density of the porous matrix material can be between 0.4 and 2g/cm 3 Between, preferably between 0.5 and 1.1g/cm 3 Between them. In particular, the density of the porous matrix material may be between 0.41 and 1.9g/cm 3 Between, preferably between 0.53 and 1.1g/cm 3 Between them.
Such a density may be advantageous in order to allow the perfume particles to be movable by the suction of the user. The density of the matrix material may be determined according to standard methods known to the skilled person.
The porosity of the porous matrix material may be between 0.11 and 0.8, preferably between 0.4 and 0.8, more preferably between 0.5 and 0.7. The porosity of the matrix material can be determined as the void volume (V p ) With the total volume of the material (V t )V p /V t Is a ratio of (2).
A porous matrix material having such porosity may enable a large amount of at least one flavoring agent to be included in the perfume particle.
The perfume particle may comprise between 40 and 80 wt%, preferably between 50 and 70 wt% of the porous matrix material of the total weight. The perfume particle may comprise between 20 and 60 wt%, preferably between 30 and 50 wt% of at least one flavouring agent of the total weight.
The porous matrix material may be water-soluble. This may ensure that only at least one flavouring agent comprised in the porous matrix material is volatilized upon inhalation by the user. The water vapor included in the user's puff may not dissolve the porous matrix material.
The porous matrix material may comprise one or more of the following: plastics, cellulosic materials, lignocellulosic materials, ceramic materials, minerals and fabrics. Preferably, the porous matrix material may be selected from: the composition comprises brown martial arts, bamboo fiber composite, cork, modal fabric composite, nonwoven fabric, cellulose composite and cyclodextrin. Especially preferred is the martial arts. The porous matrix material may comprise an open cell porous material. The voids in the open cell porous material are readily accessible to the at least one flavoring agent. This may facilitate easy impregnation of the open porous matrix material with at least one flavoring agent.
These materials may be well suited for use as porous matrix materials. These materials may be capable of absorbing a substantial amount of at least one flavoring agent.
The perfume particle may have a particle size of between 0.7 and 4.7 mm. Preferably, the particle size may be between 1.7 and 3.8 millimeters.
Such particle sizes may be particularly suitable for perfume particles configured to be movable by suction of a user.
At least one flavoring agent may be volatile. This may facilitate the volatilization of the at least one flavoring agent upon inhalation by the user. The at least one flavoring agent may be a liquid or a gel. The at least one flavoring agent may be selected from: peppermint oil, menthol, isomenthone, and menthyl acetate.
The perfume particles may also comprise at least one aerosol former. Preferably, the at least one aerosol former may be selected from: propylene glycol, glycerol, diacetate, diethyl phthalate. These aerosol formers may also be included in the aerosol in addition to the at least one flavoring agent when the user inhales on the mouthpiece. These aerosol formers may also control the rate of volatilization of the at least one flavoring agent.
The mouthpiece may include a longitudinal axis. The airflow path may be arranged in part in a direction parallel to the longitudinal axis. The airflow path may be arranged partially at an angle to the longitudinal axis. The perfume particles may be arranged in an airflow path arranged partially diagonally to the longitudinal axis. This may provide an extended airflow path through the mouthpiece and through the flavour particles. This may provide an enhanced contact time between the perfume particles and the airflow provided by the user's suction. This may facilitate the volatilization of at least one flavoring agent.
The airflow path through the mouthpiece may be arranged partially non-parallel to the longitudinal axis. In particular, the airflow path through the mouthpiece may be partially offset from a direction along the longitudinal axis. This may provide an extended airflow path through the mouthpiece. As already discussed above, this may also lead to an increase in the contact time between the perfume particles and the air stream.
The mouthpiece may further comprise a flavour compartment comprising flavour particles. The fragrance compartment may provide a compartment for fragrance particles to float in the airflow drawn by the user. The fragrance compartment may provide space for fragrance particles to move as the user draws. The perfume particle may occupy only a portion of the perfume compartment. This may provide space for the fragrance particles to move when the user draws.
The fragrance compartment may have a fragrance of between 0.5 and 1.5cm 3 Preferably 0.6 and 0.9cm 3 Average volume between. Such perfume compartments may contain between 0.4 and 0.7 grams of perfume particles.
The flavour compartment may be located in a portion of the airflow which may be arranged diagonally to the longitudinal axis of the mouthpiece. The fragrance compartment may also be located in a portion of the airflow that may be arranged in a direction that is not parallel to the longitudinal axis. This may allow the airflow path to extend through the fragrance compartment comprising the fragrance particles.
The fragrance compartment may be annular. This may provide an annular ring of flavour particles in the flavour compartment in the mouthpiece. This may provide an advantageous airflow path through the fragrance compartment. The annular flavour compartment may be arranged along the longitudinal axis of the mouthpiece.
The fragrance compartment may comprise a wall. The walls of the flavour compartment may be one or both of the inner wall of the mouthpiece or the outer wall of the mouthpiece. The inner wall of the mouthpiece may be located in the interior of the mouthpiece. The outer wall of the mouthpiece may be an outer wall of the mouthpiece. The outer wall of the mouthpiece may provide a region for the user to hold the mouthpiece and inhale aerosol from the mouthpiece.
The walls of the fragrance compartment may be in contact with the fragrance particles. Upon inhalation by the user, the fragrance particles can move and can bounce off the wall. This may provide vibration feedback to the user. If the fragrance particles are heavier, containing more of at least one flavoring agent, the vibratory feedback to the user may be stronger. Thus, the vibration feedback may provide the user with information about how much of the at least one flavoring of the mouthpiece has been used.
The fragrance compartment may comprise a fragrance compartment air inlet. The fragrance compartment air inlet may provide a passageway for an air flow generated upon user inhalation into the fragrance compartment. The fragrance compartment air inlet may be positioned upstream of fragrance particles located in the fragrance compartment.
The fragrance compartment may comprise a fragrance compartment air outlet. The fragrance compartment air outlet may provide an airflow path out of the fragrance compartment to an aerosol comprising at least one volatilized flavoring agent. The fragrance compartment air outlet may be positioned downstream of fragrance particles located in the fragrance compartment.
As used herein, the terms "upstream" and "downstream" are used to describe the relative position of a component or portion of a component of a mouthpiece or an aerosol-generating device used with the mouthpiece with respect to a direction in which air flows through the mouthpiece or aerosol-generating device along an airflow path during use of the mouthpiece or aerosol-generating device. A mouthpiece according to the present invention comprises a proximal end through which, in use, aerosol exits the mouthpiece. The proximal end of the aerosol-generating device may also be referred to as the mouth end or downstream end. The proximal end of the aerosol-generating device may be a mouthpiece connected to the aerosol-generating device. The mouth end is downstream of the distal end. The distal end of the aerosol-generating device or mouthpiece may also be referred to as the upstream end. The mouthpiece or a component or part of a component of the aerosol-generating device may be described as being upstream or downstream of each other based on their relative position with respect to the airflow path through the mouthpiece or the aerosol-generating device.
The mouthpiece may comprise an outer wall. The outer wall may comprise any suitable material suitable for use in a mouthpiece. One or both of the outer wall and the inner wall may comprise plastic, cardboard, or metal.
The mouthpiece may further comprise an inlet portion. The inlet portion may be configured to receive an aerosol. Further, the mouthpiece may comprise an outlet portion. The outlet portion may be configured for outflow of aerosol, for example, to a user. An airflow path through the mouthpiece may be arranged between the inlet portion and the outlet portion.
The inlet portion of the mouthpiece may be configured for removable connection to one or more of a cartridge for an aerosol-forming substrate, an aerosol-generating device or an aerosol-generating article. The inlet portion may be configured to receive an aerosol generated by an aerosol-forming substrate of the cartridge or aerosol-generating article.
The inlet portion of the mouthpiece may comprise a connection tap. The connection tap may be configured for detachable connection to one or more of a cartridge for an aerosol-forming substrate, an aerosol-generating device or an aerosol-generating article.
The flavour compartment air inlet may provide an airflow path between the inlet portion of the mouthpiece and the flavour compartment. Thus, the inlet portion may be configured to direct aerosol generated by the cartridge or aerosol-generating article into the fragrance compartment through the fragrance compartment air inlet.
The outlet portion of the mouthpiece may comprise an inner wall which provides an aerosol outlet for the user. The inner wall of the outlet portion of the mouthpiece may comprise a flavour outlet in fluid communication with the flavour particles. The fragrance outlet may be in fluid communication with the fragrance compartment. This may provide a flow path from the flavour particles to the aerosol outlet. The above-mentioned fragrance compartment air outlet of the fragrance compartment may correspond to a fragrance outlet.
The inner wall may have a tapered shape. The inner wall may have a larger cross-sectional area at the downstream end of the inner wall than at the upstream end. The velocity of the mixture of aerosol and at least one flavoring agent may be lower at the downstream end of the inner wall than at the upstream end. This may provide a venturi effect. This may enable better mixing of the mixture of aerosol and at least one flavouring agent prior to inhalation by the user.
The inlet portion of the mouthpiece may comprise a tubular section. The tubular section may be configured for removable connection to the cartridge. The tubular section may be arranged along the longitudinal axis of the mouthpiece.
The tubular section may enable contact with the barrel, in particular with the central hollow portion of the annular barrel.
The tubular section may include an opening at the upstream end. The opening at the upstream end may have a smaller diameter than the downstream end of the tubular section. This may result in a reduced velocity of the aerosol at the downstream end of the tubular section compared to the upstream end. This may enable better mixing of air and aerosols originating from the aerosol-forming substrate.
The mouthpiece may comprise an outer wall. The outer wall may comprise at least one mouthpiece air inlet configured for allowing ambient air to enter the mouthpiece. The inlet portion of the mouthpiece may comprise at least one mouthpiece air inlet.
The mouthpiece may further comprise an outlet seal layer. The outlet sealing layer may seal the outlet portion of the mouthpiece. The mouthpiece may further comprise an inlet sealing layer. The inlet sealing layer may seal an inlet portion of the mouthpiece. The presence of one or both of the outlet sealing layer and the inlet sealing layer may prevent evaporation of the at least one flavoring agent from the mouthpiece. The user may remove the inlet sealing layer and the outlet sealing layer before using the mouthpiece. After removing the outlet sealing layer and the inlet sealing layer, the user may connect the mouthpiece with one or both of the aerosol-generating article or the cartridge.
The invention also provides flavour particles for flavouring aerosols. The flavour particles may comprise a porous matrix material comprising at least one flavouring agent for flavouring an aerosol. The fragrance particles may be configured to be movable by suction of a user.
Another embodiment of the present invention provides a flavor particle for flavoring an aerosol. The flavour particles comprise a porous matrix material comprising at least one flavouring agent for flavouring an aerosol. The fragrance particles are configured to be movable by suction of a user.
The flavour particles may be used to provide flavouring to an aerosol generated by one or both of a cartridge comprising an aerosol-forming substrate or an aerosol-generating article comprising an aerosol-forming substrate. The flavor particles can achieve flavoring of the aerosol without the need to heat the aerosol. At least one flavoring agent of the flavor particles may be entrained in the aerosol when floating in the user-drawn air stream.
The perfume particles of the present invention may be produced by fluid bed processing. In particular, the perfume particles may be produced by two specific types of fluid bed processing, namely top spray granulation or spray dryer granulation. A fluidized bed reactor may be used. In a fluidized bed reactor, particles of a porous matrix material may be suspended in a fluid. The fluid may include at least one flavoring agent. This can occur at higher temperatures and higher pressures. This may enable at least one flavoring agent to be embedded in and absorbed by the porous matrix material. In both cases of fluidized bed processing, warm air can be blown through perforated distributors on the bottom of a vertical tubular structure (e.g., a vertical fluidized bed tower). At least one flavoring agent may be sprayed in liquid form on top of the fluidized bed column, while the porous matrix material may flow continuously in warm air from the bottom to the top of the vertical column. During fluidized bed processing, particles of porous matrix material to be impregnated with flavoring flow higher in the fluidized bed and are subjected to impregnation with flavoring at the top of the vertical fluidized bed column. Heavier perfume particles comprising porous matrix material impregnated with a flavoring tend to float at lower positions in the vertical fluidized bed tower due to their increased weight. The particles of the porous matrix material may be impregnated with a flavoring agent or a coating of flavoring agent may be provided on the particles of the porous matrix material. The particles of the porous matrix material may be porous, such as, for example, bastardite, having an average diameter of between 1 and 5 mm, preferably between 1.7 and 3.5 mm. The flavoring agent may be a liquid at the processing temperature. Flavoring agents may include salts such as sea salt, liquid food coloring, vegetable gelatin, and water. The at least one flavoring agent may include flavors such as citrus, lemon, grapefruit, spearmint, lavender, bergamot, cinnamon, and olibanum. The flavoring agent may comprise amorphous sol-gel silicon, which may enable sol-gel capture of the sensitive flavoring agent in the porous matrix material. After impregnation, the finished perfume particles are dried with heated air. Fluidized bed processors comprising vertical fluidized bed towers are sold by various companies such as Diosna GmbH, senieer or Gea AG.
The porous matrix material of the perfume particle may have a density of between 0.4 and 2g/cm 3 Between, preferably between 0.5 and 1.1g/cm 3 Between them. In particular, the density of the porous matrix material may be between 0.41 and 1.9g/cm 3 Between, preferably between 0.53 and 1.1g/cm 3 Between them. The porosity of the porous matrix material may be between 0.11 and 0.8, preferably between 0.4 and 0.8, more preferably between 0.5 and 0.7. The porous matrix material may have a porosity of between 0.11 and 0.45.
The porous matrix material may be water-soluble. This may ensure that only at least one flavouring agent comprised in the porous matrix material is volatilized upon inhalation by the user. The water vapor included in the user's puff may not dissolve the porous matrix material.
The porous matrix material may comprise one or more of the following: plastics, cellulosic materials, lignocellulosic materials, ceramic materials, minerals and fabrics. Preferably, the porous matrix material may be selected from: the composition comprises brown martial arts, bamboo fiber composite, cork, modal fabric composite, nonwoven fabric, cellulose composite and cyclodextrin.

This may enable the airflow channel to be formed only when the cartridge is connected to the mouthpiece.
The tubular section of the inlet portion may be positioned adjacent to the vaporizer assembly of the cartridge when the mouthpiece is connected to the cartridge. In particular, the upstream end of the tubular section may be positioned adjacent to the vaporizer assembly of the cartridge.

Thus, the mouthpiece of the present invention may be used to alter the flavour of an aerosol-generating article at the convenience of the user. A user may consume an aerosol-generating article employing the aerosol-generating system described herein. After use, the user may disconnect the mouthpiece from the aerosol-generating article. The user may reuse the mouthpiece or any other mouthpiece comprising flavour particles with a different flavour with another aerosol-generating article.
The aerosol-generating article may generate an aerosol by heating the aerosol-forming substrate to a temperature below the combustion temperature. Such aerosol-generating articles may also be referred to as "heated non-combustion products".
The cavity of the aerosol-generating device may have an open end into which the aerosol-generating article is inserted. The open end may be a proximal end. The cavity may have a closed end opposite the open end. The closed end may be the base of the cavity. The closed end may be closed, except for providing an air aperture disposed in the base.

The aerosol-generating device may comprise a heating element. The heating element may be configured to heat the aerosol-generating article received in the cavity. The heating element may be configured to heat the aerosol-generating article to a temperature in the range 220 degrees celsius to 400 degrees celsius, preferably 250 degrees celsius to 290 degrees celsius.

Preferably, the susceptor may be part of an aerosol-generating device or an aerosol-generating article.
As described herein, induction heating may be utilized. For induction heating, an induction coil and susceptor are provided. In general, susceptors are materials that are capable of generating heat when penetrated by an alternating magnetic field. When positioned in an alternating magnetic field. If the susceptor is electrically conductive, eddy currents are typically induced by an alternating magnetic field. If the susceptor is magnetic, another effect that generally contributes to heating is commonly referred to as hysteresis loss. Hysteresis losses are mainly due to the movement of the magnetic domain blocks within the susceptor, since the magnetic orientation of these magnetic domain blocks will be aligned with the alternating magnetic induction field. Another effect that contributes to hysteresis loss is when the magnetic domains will grow or shrink within the susceptor. In general, all these changes in susceptors that occur at or below the nanometer scale are referred to as "hysteresis losses" because they generate heat in the susceptor. Thus, if the susceptor is both magnetic and conductive, both hysteresis loss and eddy current generation will contribute to the heating of the susceptor. If the susceptor is magnetic but not conductive, hysteresis losses will be the only means of susceptor heating when penetrated by an alternating magnetic field. According to the invention, the susceptor may be electrically conductive or magnetic, or both. The alternating magnetic field generated by the induction coil or coils heats the susceptor, which then transfers heat to the aerosol-forming substrate, causing the aerosol to form. Heat transfer may be primarily by heat conduction. Such heat transfer is optimal if the susceptor is in close thermal contact with the aerosol-forming substrate.
The airflow channel may extend through the cavity. Ambient air may be drawn into the aerosol-generating device, into the cavity and towards the user through the airflow channel. The mouthpiece may be arranged downstream of the cavity. The airflow channel may extend through the mouthpiece.

The aerosol-generating device may comprise an electrical circuit. The circuit may include a microprocessor, which may be a programmable microprocessor. The microprocessor may be part of a controller. The circuit may comprise further electronic components. The circuit may be configured to regulate the supply of electrical power to the heating element, in particular to the induction coil.

The power may be supplied to the heating element in the form of current pulses. The circuit may be configured to monitor the resistance of the heating element and preferably to control the supply of electrical power to the heating element in dependence on the resistance of the heating element.
The aerosol-generating device may comprise a power source, typically a battery, within the body of the aerosol-generating device.

Detailed Description
In the following, like elements are denoted by like reference numerals throughout the drawings.
Fig. 1A shows a cross-sectional view of an embodiment of a mouthpiece 10 of the present invention. The mouthpiece 10 includes an inlet portion 10B configured to receive an aerosol and an outlet portion 10A configured to flow the aerosol out to a user. The mouthpiece 10 includes a flavour compartment 16 containing flavour particles 12. The flavour compartment comprises a flavour compartment air inlet 16A for receiving aerosol from an aerosol-forming substrate located upstream of the mouthpiece. A fragrance compartment air outlet 16B is present in the inner wall of the outlet portion for releasing a mixture of aerosol and at least one flavouring into the aerosol outlet for mixing. The inlet portion 10B of the mouthpiece 10 comprises a tubular section 18 configured for detachable connection to, for example, a cartridge containing an aerosol-forming substrate (cartridge not shown in fig. 1A). The airflow path 14, represented by the dashed line in the inlet portion 10B, extends along the longitudinal axis 22 of the mouthpiece and enters the flavour compartment 16 through the flavour compartment air inlet 16A. The flavor particles 12 are configured to be movable in a user-drawn air stream and at least one flavor included in the flavor particles becomes entrained in the aerosol in the flavor compartment 16. Subsequently, the mixture of aerosol and at least one flavoring agent exits the flavor compartment 16 through the flavor compartment air outlet 16B. The airflow path 14 in the flavour compartment 16 is arranged in part diagonally to the longitudinal axis 22 of the mouthpiece, indicated by the dotted line. This increases the airflow path through the flavour compartment 16 and the flavour particles 12, so that there is a higher likelihood of entraining a greater amount of at least one flavour in the aerosol. The inner wall 10D of the outlet portion 10A of the mouthpiece comprises a conical shape. The diameter of the inner wall at the upstream end is smaller than the diameter of the inner wall at the downstream end. This results in a reduced velocity of the aerosol and the at least one flavoring agent at the downstream end facilitating mixing of the aerosol and the at least one flavoring agent. The mouthpiece 10 also includes an outer wall 10C that includes a mouthpiece air inlet 20. The mouthpiece air inlet 20 allows ambient air to enter the mouthpiece. This ambient air may be used to generate an aerosol from an aerosol-forming substrate such as a cartridge.
Fig. 1B shows a cross-sectional view of another embodiment of a mouthpiece of the present invention. In contrast to the embodiment of the mouthpiece shown in fig. 1B, the airflow path 14 in the mouthpiece of fig. 1B extends entirely along the longitudinal axis of the mouthpiece. Both the flavor compartment air inlet 16A and the flavor compartment air outlet 16B are positioned along the longitudinal axis of the mouthpiece. The mouthpiece further comprises an inlet sealing layer 10E sealing the inlet portion 10B of the mouthpiece and an outlet sealing layer 10F sealing the outlet portion 10A of the mouthpiece. The sealing layer prevents evaporation of the at least one flavoring agent during storage of the mouthpiece and extends the shelf life of the mouthpiece. The user may remove both sealing layers before using the mouthpiece.
Fig. 2 depicts a schematic cross-sectional view of a disassembled aerosol-generating system comprising the mouthpiece 10, cartridge 24 and aerosol-generating device 32 of the present invention. As indicated by the arrow, the tubular section 18 of the inlet portion of the mouthpiece 10 may be connected to the cartridge 24 by a central hollow portion 24A of the cartridge. The cartridge 24 contains a liquid aerosol-forming substrate 23. The vaporizer assembly 30 is present in the cartridge 24 that includes a porous vaporization element 26 that is thermally conductively connected to a heater element 28. The porous evaporation element 26 is capable of absorbing the liquid aerosol-forming substrate 23. Upon heating the heater element 28, the liquid aerosol-forming substrate may be vaporized. The heater element 28 includes connection pins 28A. These connection pins are configured to be detachably connected to electrical connections 34 of the aerosol-generating device 32 (see corresponding arrows between the cartridge 24 and the aerosol-generating device 32). The aerosol-generating device further comprises a control circuit 36 and a power supply 38 for the heater element 28 of the cartridge. Such an aerosol-generating system allows for the generation of an aerosol from the aerosol-forming substrate 23 of the cartridge and subsequent flavoring of the aerosol with at least one flavoring agent of the flavor particles 12 of the mouthpiece 10.
Fig. 3 shows a cross-sectional view of the assembled aerosol-generating system of fig. 2. When the mouthpiece 10 is connected to the cartridge 24, an additional airflow path 14A is formed between the inner wall of the cartridge and the wall of the inlet portion 10B of the mouthpiece 10. Ambient air may enter this newly created airflow path 14A through the mouthpiece air inlet 20 and may be directed to the vaporizer assembly of the cartridge. At the vaporizer assembly of the cartridge, the liquid aerosol-forming substrate contained in the cartridge evaporates and mixes with ambient air to produce an aerosol. The aerosol is then directed through the tubular section 18 of the mouthpiece into the flavour compartment 16. The flavor particles 12 begin to move and float in the air stream drawn by the user, thereby releasing at least one flavoring agent. The mixture of aerosol and at least one flavoring agent exits the flavor compartment through the flavor compartment air outlet and enters the cone-shaped aerosol outlet. This aerosol outlet enables mixing of the aerosol and the at least one flavouring agent such that the mixture can then be inhaled by the user.
Fig. 4 depicts another disassembled aerosol-generating system comprising a mouthpiece 10 according to the present invention. In this aerosol-generating system, the mouthpiece 10 may be connected to the aerosol-generating article 40. This aerosol-generating article 40 comprises a hollow tube section 42 and a matrix section 44. The matrix section 44 may comprise a solid aerosol-forming matrix. The components of the mouthpiece 10 and the aerosol-generating article 40 may be inserted into the cavity 46 of the aerosol-generating device 32. The aerosol-generating device comprises a heater element 48 adjacent the cavity 46 for heating the substrate section 44 of the aerosol-generating article to a temperature below the combustion temperature of the aerosol-forming substrate. The aerosol-generating device further comprises a control circuit 38 and a power supply 36 for a heater element 48.
