Description
Technical Field
The present invention relates to a cartridge for an aerosol-generating device.
Background
It is known to provide a cartridge for an aerosol-generating device for generating an inhalable vapour. The cartridge may comprise an aerosol-forming substrate in liquid form. Such devices may heat the aerosol-forming substrate to a temperature that volatilizes one or more components of the aerosol-forming substrate without combusting the aerosol-forming substrate. The cartridge may be configured to be insertable into a cavity (e.g. a heating chamber) of an aerosol-generating device. The heating element may be arranged in or around the heating chamber to heat the aerosol-forming substrate once the cartridge is inserted into the heating chamber of the aerosol-generating device.
The user may carry an aerosol-generating device comprising a cartridge. The aerosol-generating device may be carried, for example, in a pocket or pouch. Friction with other elements located in the pocket or bag may accidentally rotate the movable part of the aerosol-generating device. This may lead to an accidental activation of the aerosol-generating device. This may lead to an accidental spillage of the aerosol-forming substrate over the aerosol-generating device.
Disclosure of Invention
It would be desirable to have a cartridge for an aerosol-generating device that enables modification of the generated aerosol. It would be desirable to have a cartridge for an aerosol-generating device that enables control of the amount of aerosol generated. It would be desirable to have a cartridge for an aerosol-generating device that prevents unwanted aerosol generation. It would be desirable to provide a cartridge for an aerosol-generating device that avoids undesired leakage of aerosol-forming substrate.
According to an embodiment of the invention, a cartridge for an aerosol-generating device is provided. The cartridge may comprise a mouthpiece. The mouthpiece may include a first fluid permeable portion and a first air inlet. The cartridge may also include a liquid storage portion. The liquid storage portion may include a reservoir for holding a liquid aerosol-forming substrate. The liquid storage portion can also include a second fluid permeable portion in fluid contact with the reservoir. In addition, the liquid storage portion may include a second air inlet. The mouthpiece and the liquid storage portion may be axially movable relative to each other, wherein the degree of contact between the first fluid permeable portion and the second fluid permeable portion may be controllable by axial movement between the mouthpiece and the liquid storage portion. Further, the mouthpiece and the liquid storage section may be rotatably movable relative to each other, wherein the degree of overlap between the first air inlet and the second air inlet may be controllable by rotational movement between the mouthpiece and the liquid storage section.
According to a further embodiment of the invention, a cartridge for an aerosol-generating device is provided. The cartridge includes a mouthpiece. The mouthpiece includes a first fluid permeable section and a first air inlet. The cartridge also includes a liquid storage portion. The liquid storage portion includes a reservoir for holding a liquid aerosol-forming substrate. The liquid storage portion also includes a second fluid permeable portion in fluid contact with the reservoir, and a second air inlet. The mouthpiece and the liquid storage section are axially movable relative to each other, wherein the degree of contact between the first fluid permeable section and the second fluid permeable section is controllable by axial movement between the mouthpiece and the liquid storage section. Furthermore, the mouthpiece and the liquid storage section are rotatably movable relative to each other, wherein the degree of overlap between the first air inlet and the second air inlet is controllable by the rotational movement between the mouthpiece and the liquid storage section.
The axial movement between the mouthpiece and the liquid storage portion may determine the degree of contact between the first fluid permeable portion and the second fluid permeable portion. This degree of contact may determine the amount of liquid aerosol-forming substrate used to generate the aerosol. This may enable a user to manipulate the composition of the aerosol by axially moving the mouthpiece relative to the liquid storage portion.
The degree of overlap between the first air inlet and the second air inlet may be controllable by rotationally moving the mouthpiece relative to the liquid storage portion. This degree of overlap may determine the amount of air used to generate the aerosol. This may enable a user to manipulate aerosol formation by rotationally moving the mouthpiece relative to the liquid storage portion.
The combination of axially and rotationally moving the mouthpiece relative to the liquid storage portion may also prevent accidental spillage of the aerosol-forming substrate. In particular, the cartridge may be held in a position during storage in which no contact is made between the first fluid permeable section and the second fluid permeable section. In addition, the cartridge may be held in a position during storage in which there is no overlap between the first air inlet and the second air inlet. This may reduce the risk of the aerosol-forming substrate accidentally leaking out of the cartridge during storage. This may increase the shelf life of the cartridge.
The first fluid permeable section may be tubular. This may allow easy axial movement of the first fluid permeable section of the cartridge relative to the second fluid permeable section of the liquid storage section.
The first fluid permeable section may be configured as a core. This may allow transport of the liquid aerosol-forming substrate via capillary forces.
The second fluid permeable portion of the liquid storage portion may be tubular. This may allow for easy axial movement of the second fluid permeable portion relative to the first fluid permeable portion of the mouthpiece.
The second fluid permeable section may be configured as a core. This may allow the liquid aerosol-forming substrate to be transported from the second fluid permeable section towards the first fluid permeable section via capillary forces.
One or both of the first fluid-permeable portion and the second fluid-permeable portion may comprise a high retention and release material.
The high retention material may comprise a capillary material having a fibrous or porous structure that forms a plurality of small pores or microchannels. The liquid aerosol-forming substrate may be transported by capillary action through the capillary material. The high retention material may comprise a plurality of fibers, threads, or other fine pore tubes forming capillary bundles. The fibers or threads may be substantially aligned to convey the liquid aerosol-forming substrate towards the delivery material. Alternatively, the retaining material may comprise a sponge-like or foam-like material. The retention material may comprise any suitable material or combination of materials. Examples of suitable materials include sponge or foam materials, ceramic or graphite based materials in the form of fibers or sintered powders, foam metal or plastic materials, fibrous materials (e.g., spun or extruded fibers such as cellulose acetate, polyester, bonded polyolefin, polyethylene, polypropylene fibers, nylon fibers, ceramic fibers), cotton, and combinations thereof. In one exemplary embodiment, the retention material comprises High Density Polyethylene (HDPE) or polyethylene terephthalate (PET).
One or both of the first fluid-permeable portion and the second fluid-permeable portion may comprise a ceramic porous material. The porous material may have a porosity of about 30% to 70%, preferably about 40% to 60%. The pore size may be 5 microns to 40 microns, preferably 5 microns to 30 microns.
The mouthpiece may comprise a tubular airflow channel. The first fluid permeable section may be disposed at a distal portion of the tubular airflow channel. This may allow the liquid aerosol-forming substrate to enter the tubular airflow channel via the first fluid permeable section. This may provide an airflow path towards the downstream end of the mouthpiece for the generated aerosol.
As used herein, the terms "distal" and "proximal" are used to describe the relative position of a section of a cartridge or a section of an aerosol-generating device used with an aerosol-generating article with respect to the direction of aerosol transport through the aerosol-generating article during use. The cartridge or aerosol-generating device according to the invention comprises a proximal end through which, in use, aerosol exits the cartridge. The proximal end of the barrel may also be referred to as the mouth end or downstream end. In use, a user draws on the downstream or mouth end of the cartridge in order to inhale an aerosol generated by the aerosol-generating system. The aerosol-generating system comprises an upstream end opposite a downstream or mouth end. The mouth end is downstream of the distal end. The distal end of the aerosol-generating device or cartridge may also be referred to as the upstream end. Based on its position relative to the direction of aerosol transport through the cartridge or aerosol-generating device during use of the cartridge or aerosol-generating device, the components or parts of the components of the cartridge or aerosol-generating device may be described as upstream or downstream of each other.
The mouthpiece may comprise a first sealing element arranged distally of the first fluid permeable section. This may prevent the liquid aerosol-forming substrate from escaping the mouthpiece in the distal direction through the first fluid permeable portion. Preferably, the first sealing element is configured as a tubular sealing element. This may provide a particularly reliable seal of the first fluid permeable section with respect to the distal end of the mouthpiece. This may also provide a reliable seal of the second fluid permeable section when the second fluid permeable section is sealingly covered by the first sealing element.
The mouthpiece may comprise a second sealing element arranged proximally of the first fluid permeable section. This may prevent the liquid aerosol-forming substrate from escaping the mouthpiece in a proximal direction through the first fluid permeable portion. Preferably, the second sealing element is configured as an annular sealing element. This may provide a particularly reliable seal of the first fluid permeable section with respect to the proximal end of the mouthpiece. This may also allow for easy axial movement of the mouthpiece relative to the liquid storage portion.
In a further embodiment of the cartridge, the mouthpiece and the liquid storage section may be axially movable relative to each other in the first position. In this first position, the first sealing element may sealingly cover the second fluid permeable portion of the liquid storage portion.
This may allow a reliable sealing of the second fluid permeable portion of the liquid storage portion by the first sealing element of the mouthpiece. This may allow the cartridge to be reliably stored in the first position.
In a further embodiment of the cartridge, the mouthpiece and the liquid storage section may be axially movable relative to each other in the second position. In the second position, the first fluid permeable portion may contact the entire inner surface of the second fluid permeable portion.
In the second position, the maximum amount of liquid aerosol-forming substrate may be capable of being transported to the first fluid permeable portion of the mouthpiece via the second fluid permeable portion for holding the liquid aerosol-forming substrate. This may be due to the first fluid permeable section contacting the entire inner surface of the second fluid permeable section. This may provide a maximum surface between the first fluid permeable portion and the second fluid permeable portion for transporting the liquid aerosol-forming substrate.
The mouthpiece and the liquid storage portion may be configured to be incrementally axially movable between a first position and a second position to an intermediate axial position, wherein in the intermediate axial position the first fluid permeable portion only partially contacts the entire inner surface of the second fluid permeable portion. The mouthpiece and the liquid storage portion may be configured to be axially movable relative to each other to a series of intermediate positions between the first position and the second position. In the intermediate third position, the first fluid permeable section may contact only one third of the entire inner surface of the second fluid permeable section. In the intermediate fourth position, the first fluid permeable section may contact half of the entire inner surface of the second fluid permeable section. In the intermediate fifth position, the first fluid-permeable portion may contact three-quarters of the entire inner surface of the second fluid-permeable portion. These intermediate axial positions may allow less than a maximum amount of the liquid aerosol-forming substrate to pass through the first fluid permeable portion and the second fluid permeable portion. Many further intermediate positions are possible between the mentioned intermediate third position, intermediate fourth position and intermediate fifth position. The cartridge of the present invention may be provided with a range of different preset settings. These preset settings may allow the user to lock the cartridge in different settings, for example, corresponding to the various intermediate axial positions or first and second positions described above.
In this context, the term "first position" refers to an axial position of the mouthpiece relative to the liquid storage portion, wherein the first fluid permeable portion of the mouthpiece does not contact a surface of the second fluid permeable portion of the reservoir.
The first air inlet may enable lateral airflow into the mouthpiece. This may allow a user to control the airflow into the mouthpiece by rotationally moving the mouthpiece relative to the liquid storage portion.
The liquid storage portion of the cartridge may comprise a central tubular cavity for at least partially receiving the mouthpiece. This may allow the mouthpiece and the liquid storage section to be particularly easily assembled in the cartridge. In particular, the central tubular cavity of the liquid storage portion may be configured to at least partially receive the tubular airflow channel of the mouthpiece. This may allow for a particularly easy axial movement of the mouthpiece relative to the liquid storage section by inserting the tubular airflow channel of the mouthpiece into the central tubular cavity of the liquid storage section. This may also enable easy rotational movement of the mouthpiece relative to the liquid storage section.
The second air inlet of the liquid storage portion may enable a side air flow to enter the central tubular cavity of the liquid storage portion. This may allow air to enter the central tubular cavity of the liquid storage portion through the first air inlet via the second air inlet. Furthermore, this may allow air to enter the tubular airflow channel of the mouthpiece through the central tubular cavity of the liquid storage portion.
The first air inlet may enable lateral airflow towards the second air inlet when the mouthpiece is received in the central tubular cavity of the liquid storage portion and when the first air inlet and the second air inlet overlap.
This may provide an airflow path through the first air inlet and the second air inlet into the central cavity of the liquid storage portion.
In a further embodiment of the cartridge, the mouthpiece and the liquid storage section may be rotatably movable relative to each other in the sixth position. In this sixth position, the first air inlet and the second air inlet may not overlap, thereby preventing airflow through the central tubular cavity into the mouthpiece.
The mouthpiece and the liquid storage section may be rotatably movable relative to each other in a seventh position in which the first air inlet and the second air inlet completely overlap, allowing airflow into the mouthpiece.
The mouthpiece and the liquid storage section may be incrementally rotatably movable between a sixth position to a seventh position to an intermediate rotational position in which the first air inlet and the second air inlet partially overlap.
Thus, the user may be able to incrementally rotationally move the mouthpiece relative to the liquid storage portion from a sixth position to a seventh position, wherein in the seventh position a maximum amount of air flows into the mouthpiece.
In particular, the mouthpiece may be movable to an intermediate eighth position relative to the liquid storage portion, wherein the first air inlet and the second air inlet overlap only by a quarter of the full overlap of the seventh position. The mouthpiece may be movable relative to the liquid storage section to an intermediate ninth position in which the first air inlet and the second air inlet overlap only in half of the full overlap of the seventh position. The mouthpiece may be movable relative to the liquid storage portion to an intermediate tenth position in which the first air inlet and the second air inlet overlap only by three quarters of the full overlap present in the seventh position. These intermediate rotational positions will allow less than a maximum amount of air to be transferred into the mouthpiece.
Many further intermediate positions are possible between the mentioned intermediate eighth position, intermediate ninth position and intermediate tenth position. The cartridge of the present invention may be provided with a range of different preset settings. These preset settings may allow the user to lock the cartridge in different settings, for example corresponding to the various intermediate rotational positions described above or the sixth and seventh positions.
This may allow the user to incrementally adjust the air flow into the mouthpiece by incrementally rotating the mouthpiece and the liquid storage portion.
The components of the cartridge including the mouthpiece and the liquid storage portion may be made of a polymeric component. For example, one or more of nylon, PBT (polybutylene terephthalate) polyester, and TPE (thermoplastic elastomer) may be used.
In further embodiments of the cartridge, the mouthpiece may comprise a susceptor. The susceptor may be configured to inductively heat the liquid aerosol-forming substrate for aerosol formation. Preferably, the susceptor is tubular. Preferably, the susceptor may be aligned with the first fluid permeable portion of the mouthpiece. The susceptor may be in fluid communication with the first fluid permeable portion of the mouthpiece. The susceptor may be porous. This may allow the liquid aerosol-forming substrate to pass through the susceptor when heated by the susceptor. The susceptor may be in fluid communication with the tubular airflow passage of the mouthpiece. This may allow the liquid aerosol-forming substrate to be transported through the susceptor into the tubular airflow channel to generate an aerosol.
In particular, this may allow the liquid aerosol-forming substrate to pass through the susceptor when heated. The liquid aerosol-forming substrate may flow out of the liquid storage portion, through the susceptor, through the first fluid permeable portion, into the second fluid permeable portion, and into the tubular airflow channel of the mouthpiece. In the tubular airflow channel, the heated liquid aerosol-forming substrate may be mixed with air from the central tubular cavity of the liquid storage portion to form an aerosol.
The susceptor may be formed of any material capable of being inductively heated to a temperature sufficient to generate an aerosol from the aerosol-forming substrate. Preferred susceptors may comprise or consist of ferromagnetic materials, such as ferromagnetic alloys, ferritic iron, or ferromagnetic steel or stainless steel. Suitable susceptors may be or include aluminum. The preferred susceptor may be heated to a temperature in excess of 250 degrees celsius.
The preferred susceptor is a metal susceptor, such as stainless steel. However, the susceptor material may also include or be made of the following varieties: graphite; molybdenum; silicon carbide; aluminum; niobium; inconel (Inconel) (superalloys based on austenitic (austenite) nickel-chromium); a metallized film; ceramics such as zirconia; transition metals such as iron, cobalt, nickel or metalloid components such as boron, carbon, silicon, phosphorus, aluminum.
The porous susceptor may comprise or consist of a conductive ceramic material, such as lanthanum-doped strontium titanate or yttrium-doped strontium titanate. The porous inductively heatable ceramic material may be a ceramic ferrite. The porous susceptor may comprise or consist of an open-pore ferrimagnetic or ferromagnetic ceramic material, such as ceramic ferrite. As used herein, ferrite is a ferrimagnetic ceramic compound derived from iron oxides such as hematite (Fe 2O3) or magnetite (Fe 3O4) and oxides of other metals.
Stainless steel mesh may be used as the porous susceptor.
The porous susceptor may have a porosity of between 35% and 80%, preferably between 45% and 65%, most preferably between 50% and 60%. As used herein, the term "porosity" refers to the fraction of void space in the susceptor. The porosity of the susceptor may be selected to enable lateral airflow through the susceptor. The porosity may additionally or alternatively be affected by providing slits or holes in the susceptor.
The liquid aerosol-forming substrate may comprise at least one aerosol-forming agent. The aerosol former is any suitable known compound or mixture of compounds that, in use, promotes the formation of a dense and stable aerosol and is substantially resistant to thermal degradation at the operating temperature of the system. Suitable aerosol formers are well known in the art and include, but are not limited to: polyols such as triethylene glycol, 1, 3-butanediol, and glycerol; esters of polyols such as monoacetin, diacetin or triacetin; and aliphatic esters of monocarboxylic, dicarboxylic, or polycarboxylic acids, such as dimethyl dodecanedioate and dimethyl tetradecanedioate. The aerosol former may be a polyol or a mixture thereof, such as triethylene glycol, 1, 3-butanediol, and glycerol. The aerosol former may be propylene glycol. The aerosol former may include both glycerol and propylene glycol.
The liquid aerosol-forming substrate may comprise other additives and ingredients, such as fragrances. The liquid aerosol-forming substrate may comprise water, solvents, ethanol, plant extracts and natural or artificial flavours. The liquid aerosol-forming substrate may comprise nicotine. The liquid aerosol-forming substrate may have a nicotine concentration of between about 0.5% and about 10%, for example about 2%.
The present invention also provides an aerosol-generating system comprising a cartridge as described herein. The aerosol-generating system may further comprise an aerosol-generating device, wherein the aerosol-generating device may comprise a chamber for receiving the cartridge.
According to a further embodiment of the invention, an aerosol-generating system is provided. The aerosol-generating system comprises a cartridge as described herein. Furthermore, the aerosol-generating system comprises an aerosol-generating device. The aerosol-generating device comprises a cavity for receiving the cartridge.
The aerosol-generating device of the aerosol-generating system may provide the heating element. The heating element may be configured to heat the liquid aerosol-forming substrate to generate an aerosol.
The heating element may comprise an inductor coil. The inductor coil may be configured to heat a susceptor of the mouthpiece. This may enable heating of the liquid aerosol-forming substrate via induction heating to generate an aerosol.
The inductor coil of the heating element may at least partially surround the cavity for receiving the cartridge.
This may allow the inductor coil to heat the susceptor of the mouthpiece when the cartridge is fully received in the cavity.
The susceptor of the mouthpiece may be configured to: the cartridge may be aligned with respect to the inductor coil of the heating element of the aerosol-generating device by axially moving the mouthpiece with respect to the aerosol-generating device when the cartridge is fully received in the cavity of the aerosol-generating device. The degree of horizontal alignment between the inductor coil and the susceptor of the mouthpiece may determine the degree of heating of the susceptor.
In induction heating, the susceptor may be heated by an alternating magnetic field of an induction heating element. This may also heat the liquid aerosol-forming substrate adjacent to or transported through the susceptor. For induction heating, the heating element preferably comprises an induction coil. An alternating current may be supplied to the induction coil for generating an alternating magnetic field. The alternating current may have a high frequency. As used herein, the term "high frequency oscillating current" refers to an oscillating current having a frequency between 500 kilohertz and 30 megahertz. The frequency of the high frequency oscillating current may be about 1 megahertz to about 30 megahertz, preferably about 1 megahertz to about 10 megahertz, and more preferably about 5 megahertz to about 8 megahertz.
The aerosol-generating device may comprise a power source (typically a battery) within a housing of the aerosol-generating device. In one embodiment, the power source is a lithium ion battery. Alternatively, the power source may be a nickel-metal hydride battery, a nickel cadmium battery, or a lithium-based battery such as a lithium-cobalt, lithium-iron-phosphate, lithium titanate, or lithium-polymer battery. Alternatively, the power supply may be another form of charge storage device, such as a capacitor. The power supply may need to be recharged and may have a capacity that enables sufficient energy to be stored for one or more use experiences; for example, the power supply may have sufficient capacity to continuously generate aerosols for a period of about six minutes or a multiple of six minutes. In another example, the power source may have sufficient capacity to provide a predetermined number of puffs or discrete activations of the heating element.
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 control unit. 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 resistive heating element or the conductive heating element. The power may be continuously supplied to the heating element after activation of the aerosol-generating device, or may be intermittently supplied, such as on a port-by-port basis. 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 present invention also provides a method for controlling aerosol generation in an aerosol-generating system as described herein. The method may comprise axially moving the mouthpiece and the liquid storage portion relative to each other, thereby controlling the supply of liquid aerosol-forming substrate. The method may also include rotationally moving the mouthpiece and the liquid storage portion relative to each other, thereby controlling the airflow into the mouthpiece.

The method comprises axially moving the mouthpiece and the liquid storage portion relative to each other, thereby controlling the supply of liquid aerosol-forming substrate. Further, the method comprises rotationally moving the mouthpiece and the liquid storage portion relative to each other, thereby controlling the airflow into the mouthpiece.
Such a method may provide the user with different options for manipulating aerosol generation in an aerosol-generating system. This may be accomplished by axially and rotationally moving the mouthpiece and the liquid storage section relative to each other.

Detailed Description
Fig. 1 shows a perspective view of a cartridge 10 according to the present invention. The cartridge 10 includes a mouthpiece 12 and a liquid storage portion 18. The mouthpiece 12 includes a mouthpiece cover 30 fluidly connected to the tubular airflow channel 26. At the distal end of the tubular airflow channel 26 there is a first fluid permeable section 14. This first fluid permeable section 14 is flanked by a first sealing element 16 and a second sealing element 28, both of which can provide a seal such that liquid aerosol-forming substrate conveyed through the first fluid permeable section does not inadvertently spill over the first fluid permeable section. The mouthpiece 12, and in particular the tubular airflow channel 26 thereof, is insertable into the central tubular cavity 32 of the liquid storage section 18. This central tubular cavity 32 is surrounded by a tubular reservoir 24 holding a liquid aerosol-forming substrate. A second fluid permeable section 22 is present at the distal end of the liquid storage section 18. This second fluid permeable portion 22 is in fluid communication with the liquid aerosol-forming substrate of the reservoir 20. At the distal end of the liquid storage portion 18 there is an external air inlet 24, which allows ambient air to enter the liquid storage portion.
Fig. 2-4 depict an aerosol-generating device 34 comprising a cavity 36 for receiving the cartridge 10. In particular, the mouthpiece may be introduced into the liquid storage portion 18 of the cartridge 10. This cartridge 36 may then be received in the cavity 36 of the aerosol-generating device 34. The aerosol-generating device 34 also comprises an inductor coil 38 configured to heat a susceptor portion present in the cartridge, in particular a susceptor portion present in a mouthpiece (as described below), in order to provide the aerosol to the user.
Fig. 5 depicts the lower portion of the cartridge 10 with the tubular airflow channel 26 of the mouthpiece 10 partially inserted into the central tubular cavity 32 of the liquid storage portion. Fig. 5 shows a first position in which the first sealing element 16 sealingly covers the second fluid permeable portion of the liquid storage portion. This first position thus prevents the liquid aerosol-forming substrate from being transported from the reservoir 20 to the mouthpiece. Cartridges according to the present invention may be marketed and sold in a location that reliably holds a liquid aerosol-forming substrate in the reservoir 20. The tubular airflow channel 26 of the mouthpiece 12 also includes a first fluid permeable portion 14 in fluid connection with the tubular porous susceptor 15. The first fluid permeable section is fluidly connected to the tubular porous susceptor. Neither the first fluid-permeable portion 14 nor the tubular susceptor 15 is in fluid contact with the second fluid-permeable portion 22 of the reservoir 20, so that the liquid aerosol-forming substrate is held in the reservoir. The lower portion of the liquid storage portion 18 also includes an external air inlet 24 for air to pass from the cavity of the aerosol-generating device into the interior of the cartridge.
Fig. 6 shows the lower portion of the cartridge 10 after the tubular airflow channel 26 of the mouthpiece has been fully inserted into the central tubular cavity by axial movement (as indicated by the arrow) of the mouthpiece relative to the liquid storage portion. In this second position, the first fluid-permeable portion 14 is in complete fluid communication with the second fluid-permeable portion 22 of the reservoir 20. This second position allows the liquid aerosol-forming substrate to leave the reservoir 20 through the second fluid permeable portion 22 into the first fluid permeable portion 14 and through the tubular porous susceptor 15 of the tubular airflow channel 26. The transport of the liquid aerosol-forming substrate through the second fluid permeable section, the first fluid permeable section and the porous susceptor is indicated by the dashed arrow in fig. 7.
Fig. 8 depicts the generation of aerosol 17 in the tubular airflow channel 26 of the mouthpiece when the tubular porous susceptor 15 is heated by the inductor coil 38 of the aerosol-generating device. The liquid aerosol-forming substrate is transported from the reservoir 20 to the first fluid permeable portion 14 of the mouthpiece through the second fluid permeable portion 22 of the liquid storage portion. Subsequently, the liquid aerosol-forming substrate passes through the porous susceptor element 15 and is heated. In the tubular airflow channel 26, the evaporated aerosol-forming substrate is mixed with air entering the airflow channel through the external air inlet 24 and the first and second air inlets, such that an aerosol 17 is formed (the first and second air inlets are not shown in fig. 6). The second sealing element 28 and the first sealing element 16 of the mouthpiece prevent any liquid aerosol-forming substrate from escaping into the central tubular cavity 32 of the cartridge.
Fig. 9 shows in an upper part a cross-sectional view of a lower part of the cartridge in a first axial position of the mouthpiece relative to the liquid storage section. The second fluid permeable portion 22 of the reservoir 20 is blocked by the first sealing element 16 of the tubular airflow channel 26 of the mouthpiece. Thus, the first fluid permeable portion 14 of the tubular airflow channel 26 of the mouthpiece is not in contact with the second fluid permeable portion 22 such that transport of liquid aerosol-forming substrate from the reservoir 20 is blocked. The tubular airflow channel 26 of the mouthpiece also comprises a first air inlet tubular portion 17 comprising a first air inlet 17A. The liquid storage portion comprises a second air inlet tubular portion 40 which also comprises a second air inlet 40A as indicated by the dashed line in fig. 9. The first air inlet tubular portion 17 covers the second air inlet 40A such that air entering the cartridge through the external air inlet 24 cannot enter the tubular airflow passage. This position corresponds to a sixth rotational position of the mouthpiece relative to the liquid storage section, wherein the first air inlet and the second air inlet do not overlap, thereby preventing airflow into the mouthpiece. The lower part of fig. 9 shows a cross-sectional view along a plane indicated with reference numeral 50 and indicated in the upper part of fig. 9 by a dashed line through the first air inlet tubular portion and the second air inlet tubular portion. This lower portion shows that the second air inlet 40A is covered by the first air inlet tubular portion 17, thereby preventing airflow into the mouthpiece. This first axial position and this third rotational position of the mouthpiece relative to the liquid storage portion prevents aerosol formation from the liquid aerosol-forming substrate. Thus, the cartridge may be stored in such a child-resistant position.
Fig. 10 depicts in the upper part a cross-sectional view of the lower part of the cartridge, wherein the tubular airflow channel 26 of the mouthpiece has been fully inserted into the liquid storage part by axial movement of the mouthpiece relative to the liquid storage part (indicated by arrow 21). This axial position of the mouthpiece relative to the liquid storage portion corresponds to a second axial position of the mouthpiece relative to the liquid storage portion. In this second final axial position, the first fluid permeable portion contacts the entire inner surface of the second fluid permeable portion such that a maximum amount of liquid aerosol-forming substrate may be delivered. In this second axial position, as already described above with respect to fig. 6, a flow path of liquid aerosol-forming substrate exists from the second fluid permeable section 22 to the first fluid permeable section 14 to the porous susceptor 15. This flow path allows the liquid aerosol-forming substrate to flow to the susceptor in order to form an aerosol (the porous susceptor 15 is not shown in fig. 10). As indicated by arrow 23, the mouthpiece has been moved rotationally relative to the liquid storage portion such that the first air inlet tubular portion 17 no longer covers the second air inlet 40A. In this seventh rotational position of the mouthpiece relative to the liquid storage section, the first air inlet and the second air inlet completely overlap, thereby allowing maximum airflow into the mouthpiece. The lower part of fig. 10 shows a cross-sectional view along a plane with reference numeral 50, and this plane is indicated in the upper part of fig. 10 by a dashed line through the first air inlet tubular portion and the second air inlet tubular portion. This lower portion shows the first air inlet tubular portion 17 fully retracted from the second air inlet such that the first air inlet 17A and the second air inlet 40A fully overlap, allowing a maximum amount of air to pass through. This second axial position and this seventh rotational position of the mouthpiece relative to the liquid storage portion allows the aerosol to be formed with a maximum amount of aerosol and a maximum amount of air.
Fig. 11 shows a cross-sectional view of the lower portion of the cartridge in the upper portion, with the mouthpiece and the liquid storage portion in a second axial position relative to each other, with the first fluid permeable portion contacting the entire surface of the second fluid permeable portion, thereby allowing a maximum amount of liquid aerosol-forming substrate to be delivered for aerosol formation. The contact area between the first fluid permeable section and the second fluid permeable section is indicated by a dashed line. In comparison to fig. 10, the mouthpiece and the liquid storage section are in an intermediate ninth rotational position, wherein the first air inlet 17A and the second air inlet 40A only partially overlap to half of the maximum overlap. This allows a moderate amount of air to pass through the first air inlet and the second air inlet. The lower part of fig. 11 shows a cross-sectional view along a plane with reference numeral 50, and this plane is indicated in the upper part of fig. 11 by a broken line through the first air inlet tubular part and the second air inlet tubular part. This lower portion shows that the first air inlet tubular portion 17 still covers half of the second air inlet 40A so that only half of the maximum amount of air can pass through. This second axial position and this intermediate ninth rotational position of the mouthpiece relative to the liquid storage portion allows aerosol formation with a maximum amount of liquid aerosol-forming substrate and approximately half of the maximum amount of air.
Fig. 12 shows a cross-sectional view of the lower part of the cartridge 10 in the upper part. The mouthpiece and the liquid storage portion are in an intermediate axial position relative to each other. In this intermediate axial position, the first fluid permeable portion only partially contacts the second fluid permeable portion of the reservoir. The contact area between the first fluid permeable section and the second fluid permeable section is indicated by a dashed line. Similar to fig. 11, the mouthpiece and the liquid storage section are in an intermediate ninth rotational position, wherein only half of the maximum amount of air may pass through the first air inlet and the second air inlet. This intermediate second axial position and this intermediate ninth rotational position of the mouthpiece relative to the liquid storage portion allows aerosol formation using only a portion of the amount of liquid aerosol-forming substrate and half of the maximum amount of air.
