Description

[0001] The present invention relates to an aerosol-generating article for providing electrical stimulation to a user, a holding device for such an aerosol-generating article, and a holder comprising such an aerosol-generating article.

[0002] An aerosol-generating article is understood herein to be a disposable, single-use consumable article for use with an electrically heated smoking system that generates an aerosol from the aerosol-generating article.

[0003] For example, WO 2017 / 153467 A1 discloses an aerosol-generating product including an aerosol-forming substrate and a plurality of electric fuses. The plurality of electric fuses are spaced apart from one another, and each electric fuse is positioned proximate to a portion of the aerosol-forming substrate. WO2019 / 185715 A1 discloses an aerosol-generating device for receiving an aerosol-generating product, comprising a circuit, the circuit comprising a controller for determining a change in an electrical characteristic of the circuit. The change in the electrical characteristic of the circuit is caused by a user interacting with an aerosol-generating product received by the device. CN 107 657 999A relates to an electronic intelligent smoking cessation filter and a smoking cessation device. In addition, a device is known that stimulates taste buds by non-invasive electric waves so that the receptors detect basic tastes based on frequency, heat and temperature, wherein the pulses are sent and modulated by the device.

[0004] Prior art aerosol generating articles have many advantages over conventional cigarettes and cigars, but still leave room for improvement, particularly in providing aroma and flavor, when compared to the standard performance of conventional smoking articles, including conventional cigarettes and cigars.

[0005] It is therefore an object of the present invention to provide improved aerosol-generating articles which provide aroma and flavour aspects.

[0006] The objects of the present disclosure are solved by the subject matter of the independent claims, wherein other embodiments are incorporated in the dependent claims.It should be noted that the aspects of the present disclosure described below are applicable to aerosol generating articles for providing electrical stimulation to a user, holding devices for aerosol generating articles, and holders comprising such aerosol generating articles.

[0007] According to one aspect of the present disclosure, there is provided an aerosol-generating article for providing electrical stimulation to a user. The aerosol-generating article comprises an aerosol-forming substrate, a first electrode and a second electrode.

[0008] The first electrode is at a first location on the aerosol-forming substrate to provide a first electrical contact to a user.

[0009] The second electrode is at a second position at the front face of the aerosol-forming substrate to provide a second electrical contact to the user, wherein the second position is different from the first position to enable a potential to be provided between the first and second electrodes to provide electrical stimulation to the user.

[0010] The aerosol-generating articles of the present invention may provide aroma and flavor aspects by providing electrical stimulation to the user's taste buds during consumption.For example, the aerosol-generating article may stimulate the taste buds of the user's tongue via electrical signals.

[0011] In other words, electrical pulses can be used to provide electrical taste stimulation on the tongue. Stimulation via electrical potential can allow users to experience salty, bitter, sour, sweet and / or umami tastes. These stimulations can enhance the user's experience of aroma and flavor. These electrically generated aromas and flavors can improve or change the user's sense of flavor. The electrically induced flavor sensation can be similar to the flavor of conventional cigarettes and cigars. Alternatively, the electrically induced flavor sensation can enhance the user's experience by providing a salty, bitter, sour, sweet and / or umami sensation. This enhanced flavor experience can make it easy for users to switch from conventional cigarettes and cigars to aerosol-generating products.

[0012] The simulated taste perception generated by electrically stimulating the taste buds of the user's tongue can improve the flavor sensed by the user without adding compounds to the aerosol-generating article. As a result, the required number of ingredients in the aerosol-generating article and the cost of the aerosol-generating article are not increased. The aerosol-generating article of the present invention can further allow for specific locations of electrodes to ensure adequate and ergonomic functionality.

[0013] The aerosol generating article may be understood as a disposable single-use consumable for use with an electrically heated smoking system that generates an aerosol from the aerosol generating article. The aerosol generating article may include a mouth end configured to be inserted into a user's mouth. The opposite end of the aerosol generating article may be configured to be inserted into a heated smoking system that generates an aerosol from the aerosol generating article. The aerosol generating article may include a mouthpiece and an aerosol-forming substrate wrapped in at least a tipping paper.

[0014] Aerosol formation substrate can be understood as a strip product that generates aerosol when heated. Aerosol formation substrate can be tobacco. Tobacco can be shredded, granular, molded, rolled, corrugated or otherwise processed. Aerosol formation substrate can be herbs or plant materials other than tobacco that can be processed similarly. Aerosol formation substrate can be a flavoring agent such as menthol or eucalyptus, and can be in liquid form or mixed with tobacco or other plant materials. During consumption, aerosol formation substrate is heated, and air flows through or passes through aerosol formation substrate, and the aerosol formed from the heated substrate is delivered to the user's mouth and lungs. This aerosol has a flavor derived from aerosol formation substrate. The aroma and flavor of the aerosol derived from the aerosol formation substrate can be enhanced by the taste buds in the tongue of the user through electrical stimulation.

[0015] The first electrode and the second electrode are different electrodes. They are positioned at different locations to provide different contact areas to the user. For example, the user can contact the first electrical contact with his tongue. For example, the user can contact the second electrode with another part of his tongue or his lips. The electrodes can be made of conductive materials, preferably metals, and more preferably silver compounds.

[0016] The front face of the aerosol generating article may be understood as the end face of the aerosol generating article. The front face may be at the mouth end of the aerosol generating article. The front face may extend substantially perpendicularly or at an angle to the longitudinal direction and / or the lateral surface of the aerosol generating article. The front face may be accessible to the tongue of the user, and in particular to the tip of the tongue. This means that, when in use, the electrode at the front face may be in a position where it is touched by the tongue and the taste buds located on the tongue. The electrode may provide an electrical potential to the tip of the tongue, which is particularly sensitive to taste perception (e.g., salty taste).

[0017] The lateral surface of the aerosol-generating article may be understood to be different from the front face of the aerosol-generating article. It may be an outer surface of the aerosol-generating article extending along the longitudinal direction of the aerosol-generating article. The lateral surface may be a circumferential or peripheral surface of the aerosol-generating article.

[0018] The potential between the first electrode and the second electrode can cause a potential difference between a portion of the tongue and another portion of the mouth. The potential difference can stimulate the taste buds of the tongue, giving the tongue an artificial taste to improve the user's flavor perception.

[0019] In an embodiment, the first electrode is also at the front of the aerosol-forming substrate. Thus, both electrodes are at the front of the aerosol-forming substrate. They share the front. They may be only at the surface of the front, or at least one of the electrodes may extend further around a portion of the lateral surface of the aerosol-forming substrate. In the first case, the electrodes together form a disk at the front. In the second case, the electrodes together form a cover around a portion of the front and lateral surfaces of the aerosol-forming substrate. The front may be accessible to the user's tongue, and in particular to the tip of the tongue. This means that, when in use, the two electrodes at the front may be in a position where they are touched by the tongue and its taste buds. The two electrodes may provide potentials to different points on the tip of the tongue that are particularly sensitive to taste perception (e.g., salty taste).

[0020] In another embodiment, the first electrode is on a lateral surface of the aerosol-forming substrate. The first electrode may at least partially or completely surround a portion of the lateral surface of the aerosol-generating article. The first electrode may be in the form of a complete or discontinuous band or ring surrounding the aerosol-forming substrate.

[0021] When the first electrode is on the lateral surface of the aerosol-forming substrate, it may be accessible to the user's tongue and in particular to the central area on the tongue. This means that when in use, the first electrode may be at a position where it is touched by the central part of the tongue, which is different from the tip of the tongue and is "behind" the tip of the tongue. It may provide electrical stimulation of the central part of the tongue and the taste buds located on the tongue. The first electrode may provide a potential to the central area on the tongue to provide a potential difference between the first electrode at the central area on the tongue and the second electrode at the tip of the tongue. The potential difference may stimulate the taste buds of the tongue to give the tongue an artificial taste. The electrode may provide a potential to different parts of the tongue (which may be sensitive to different taste perceptions than the tip of the tongue).

[0022] When the first electrode is on the lateral surface of the aerosol-forming substrate, it is accessible to the lips of the user. The first electrode may be accessible to the lower lip, upper lip or both lips of the user. This means that the first electrode may be located in a position where it is touched by at least one lip of the user when in use. The first electrode may provide a potential to the lips to provide a potential difference between the first electrode at the lips and the second electrode at the tongue. Only one electrode may provide a potential to the taste buds of the tongue, while the other electrode contacts the lips, which may be more sensitive to other perceptions (such as temperature).

[0023] Of course, the first electrode may be arranged at the front and lateral surfaces of the aerosol-forming substrate to be accessible to the tongue and lips of the user. In all cases, the first electrode and the second electrode may provide a potential difference to different parts of the mouth. The potential difference between the first electrode and the second electrode may stimulate the taste buds of the tongue to give the tongue an artificial taste.

[0024] The aerosol-forming substrate may further comprise a third electrode accessible to a third area of ​​the mouth, the third electrode being different from the first electrode and the second electrode. As a result, three different body parts of the user may be used for taste stimulation, for example the tongue, the upper lip and the lower lip, or a first part of the tongue, a second different part of the tongue and the lips. This may also enhance the user experience. Of course, the aerosol-forming substrate may also comprise even more than three electrodes.

[0025] In an embodiment, the first electrode and the second electrode may be electrically connected to a power source to provide a potential between the first electrode and the second electrode. In particular, they may be reversibly connected or connected to the power source. The power source may be configured to provide a potential between the first electrode and the second electrode to stimulate taste buds. The power source may be a battery or a battery pack. It may be rechargeable.

[0026] In an embodiment, the potential may be an alternating potential. It may have a frequency in the range of 50 Hz to 1200 Hz, preferably 500 Hz to 700 Hz. Such frequencies may have a significant effect on human tissue without causing vibrations of the electrodes.

[0027] In an embodiment, the power supply may be configured to provide the potential at a current ranging from 20 μA to 300 μA, preferably 20 μA to 200 μA, more preferably 40 μA to 180 μA, and even more preferably 100 μA to 130 μA. The current may be an alternating current, preferably with 20 μA steps, to provide a discernible stimulation intensity.

[0028] In an embodiment, the first electrode may be electrically connected to a first conductive element extending at least partially along the aerosol-forming substrate. The first conductive element may be electrically connected to a first electrical terminal arranged at the aerosol-forming substrate. The first electrical terminal may be electrically connected to a power source. The electrical terminal may be located at the center of the aerosol-generating article to keep the electrical terminal at a safe distance from the heating of the aerosol-generating article.

[0029] In an embodiment, the second electrode may be electrically connected to a second conductive element extending at least partially along the aerosol-forming substrate. The second conductive element may be electrically connected to a second electrical terminal arranged at the aerosol-forming substrate. The second electrical terminal may be electrically connected to a power source. Again, the position of the electrical terminal may be at the center of the aerosol-generating article to keep the electrical terminal at a safe distance from the heating of the aerosol-generating article.

[0030] The electrode may extend substantially perpendicular to the longitudinal extension of the corresponding conductive element. In this context, "substantially" is intended to indicate to a person skilled in the art that the term "perpendicular" is not intended to mean only completely perpendicular, but may include ordinary deviations from completely perpendicular. Thus, in this case, "substantially perpendicular" means that the electrode may deviate from the longitudinal extension of the conductive element by one degree, two degrees, three degrees, four degrees, five degrees, five to ten degrees, and up to twenty-five degrees from ninety degrees. The term "substantially" is used throughout this specification accordingly. The longitudinal extension of the conductive element may extend substantially perpendicular to the longitudinal extension of the corresponding electrical terminal.

[0031] The electrodes, conductive elements and / or electrical terminals may be at least partially made of conductive materials (eg, conductive polymers, conductive composite materials, metallic materials, etc.).

[0032] The aerosol generating article may include an aerosol-forming substrate wrapped at least in a plugging paper and optionally also in a wrapping paper. The aerosol generating article may further include a mouthpiece arranged at the mouth end of the aerosol generating article and configured to contact the user's mouth. The mouthpiece or filter segment may also be wrapped in at least one piece of plugging paper. At the mouth end, the plugging paper may be folded back (towards the opposite free end) to form a rounded smooth end. This prevents conductive elements extending in the longitudinal direction from touching the user's mouth and causing discomfort to it. The free end or part of the aerosol generating article may also include only the aerosol-forming substrate that is not wrapped in at least one piece of plugging paper. The conductive elements extending in the longitudinal direction may extend along the aerosol-forming substrate and / or at least partially along at least one piece of plugging paper. The conductive elements may be provided on the inside or outside of the plugging paper.

[0033] In an embodiment, the aerosol-generating article may include a first tipping paper and a second tipping paper. The first electrical terminal and the second electrical terminal may be disposed in the first tipping paper. The first electrode and the second electrode may also be optionally disposed in the first tipping paper. A heating element (e.g., a strip susceptor) may also be optionally disposed in the first tipping paper. The first conductive element and the second conductive element may be disposed at the second tipping paper.

[0034] The first and second tipping papers may be wrapped together or may overlap such that the first electrical terminal electrically contacts the first conductive element and the second electrical terminal electrically contacts the second conductive element. This means that the two tipping papers may be placed to be wrapped together or overlap such that the first tipping paper completes the electrical connection with the second tipping paper in a way such that the electrical terminals, conductive elements and / or electrodes may make physical and electrical contact. As a result, the assembly of the aerosol-generating article is very simple and cost-effective.

[0035] In summary, the aerosol-generating articles of the present invention may optionally be used for taste stimulation using electrical pulses of alternating potential with different frequencies and / or direct current within a controlled temperature range (see further below). The current, frequency and / or temperature alone or in combination may result in different and improved taste perceptions caused by electrical stimulation of the user's taste buds.

[0036] According to another aspect of the present disclosure, a holding device for an aerosol generating article is provided. The holding device for an aerosol generating article includes a receiving portion, a first electrical portion, and a second electrical portion. The receiving portion is configured to receive an aerosol generating article as described above. The first electrical portion and the second electrical portion are arranged in the receiving portion to electrically contact a first electrode and a second electrode of the aerosol generating article.

[0037] The receiving portion may be a cavity, and preferably a tubular cavity, to accommodate the aerosol-generating article.When the aerosol-generating article is inserted into the receiving portion, the first and second electrical portions of the receiving portion may make electrical contact with the first and second electrodes of the aerosol-generating article.

[0038] In an embodiment, the holding device may further include a heating element, which is configured to heat the aerosol generating article to generate an aerosol. The heating element may be arranged at the receiving portion. It may be arranged to at least partially surround at least a portion of the aerosol generating article and / or be inserted into at least a portion of the aerosol generating article. The heating element may be one or more heating units, such as heating coils, preferably induction heating coils, sensor strips, resistive heating elements, etc. The holding device may include an air inlet opening. It can be used as an opening for the availability of ambient air, which is used for aerosol inhalation by the user and / or to cool the holding device to prevent overheating.

[0039] In an embodiment, the first electrical portion and the second electrical portion of the receiving portion may be electrically connected to a power source. The power source may be part of the holding device, or may be electrically connected to the holding device only. The power source may be configured to provide a potential between the first electrode and the second electrode of the aerosol generating article. Thus, the power source may be electrically connected to the first electrode and the second electrode of the aerosol generating article. In an embodiment, the power source is a rechargeable battery.

[0040] In an embodiment, the power supply may additionally be configured to provide energy for heating the aerosol-generating article to provide the aerosol. Thus, the power supply may be electrically connected to the heating element. This means that the power supply may be the only power supply and it may be used to provide a potential between the first electrode and the second electrode and to provide energy for heating the aerosol-generating article to generate the aerosol. This makes the holding device very efficient and / or allows a reduced number of components. Of course, there may also be two different power supplies for heating the aerosol-generating article and for providing a potential between the electrodes.

[0041] In an embodiment, the holding device may comprise or may be electrically connected to a control unit. The control unit may be an electronic control unit, which manages the operation of the holding device in terms of energy management, aerosol generation and / or stimulation. The control unit may be configured to control the power supply. It may control the amount of electrical potential between the first electrical part and the second electrical part of the receiving part, and thus control the amount of electrical potential between the first electrode and the second electrode of the aerosol generating article. As a result, the control unit may control the intensity or intensity of the electrical stimulation. This may allow the holding device to be adapted to each user. The control unit may further be configured to control a heating element. As a result, the control unit may control the temperature of the aerosol generating article, and thereby control the aerosolization of the aerosol generating article.

[0042] In an embodiment, the holding device may further include at least a temperature control element. The temperature control element may be arranged at the receiving portion. It may be arranged to at least partially contact the first electrical part and the second electrical part. The temperature control element may be configured to control heat transfer between the first electrical part and the second electrical part and the first electrode and the second electrode of the aerosol generating article. Thereby, it may be configured to control the temperature of the first electrode and / or the second electrode that can be touched by the user. For example, the temperature control device may be a temperature sensor, which senses the temperature at the heating element and is controlled by the control unit. For example, if a threshold temperature is measured at the heating element, the control unit may stop providing energy from the power supply to prevent the device from overheating.

[0043] In an embodiment, the temperature control element may be configured to control the temperature of the first electrode and / or the second electrode of the aerosol-generating article within the range of 20 to 35 degrees C, preferably 22 to 25 degrees C. This temperature range appears to be very comfortable for the user's mouth.

[0044] The temperature control element may be used to heat the first electrical part and / or the second electrical part, and thereby heat the first electrode and / or the second electrode of the aerosol generating article, to provide a thermal stimulus to the user. The thermal stimulus may further enhance the user experience. The temperature control element may cooperate with a heating element for heating the aerosol generating article to provide an aerosol, and / or may include an additional heating unit for heating the first electrical part and / or the second electrical part only.

[0045] The temperature control element may additionally or alternatively be used to cool the first electrical portion and / or the second electrical portion, and thereby cool the first electrode and / or the second electrode of the aerosol-generating article, to avoid uncomfortable thermal perception at the tongue and / or lips of the user. Thus, the temperature control element may comprise at least a heat sink. The heat sink may be a thermoelectric cooler, for example a micro-Peltier element.

[0046] The temperature control element may allow heat transfer relative to the first electrical portion and / or the second electrical portion and thereby relative to the first electrode and / or the second electrode to cool or heat the first electrode and / or the second electrode. In an embodiment, the temperature control element may therefore be in contact with the housing of the holding device to transfer heat from the receiving portion holding the temperature control element to the environment via the housing of the holding device. In order to provide sufficient thermal capacity for heat transfer, the housing of the holding device may be made of a thermally conductive material, which allows thermal energy to be dissipated from the temperature control element to the ambient air. The housing of the holding device may be made of a dense material (e.g., aluminum or ceramic) that allows storage and dissipation of thermal energy. Additional heat sink materials may be used.

[0047] In an embodiment, the temperature control element may further include a thermal paste. The thermal paste may be arranged between the first electrical part and / or the second electrical part and the housing of the holding device. The thermal paste may further improve heat transfer and thereby improve heating and / or cooling of the first electrode and / or the second electrode.

[0048] In an embodiment, the retaining device may further include a multi-terminal ring connector module. The multi-terminal ring connector module may be arranged in the retaining device. The multi-terminal ring connector module may be arranged in and around the inner circumference of the receiving portion. In a cross section, the multi-terminal ring connector module may include a plurality of segments. The segments may be arranged together with the cladding. The cladding may be made of a polymer, a composite material, a ceramic, etc.

[0049] In side view, the plurality of segments form a plurality of conductive elements or tracks that may extend at least partially along the aerosol-forming substrate, the tipping paper and / or the aerosol-generating article. At least two of these conductive elements may be electrically connected to a first electrode and a second electrode of the aerosol-generating article to provide a potential from a power source to a user. In particular, the first segment in cross section forms a first conductive element that extends longitudinally and is electrically connected to the first electrode. The second segment in cross section forms a second conductive element that extends longitudinally and is electrically connected to the second electrode.

[0050] In an embodiment, the holding device may further comprise a gyroscopic sensor and a position control unit. The position control unit is configured to select a first conductive element and a second conductive element from a plurality of conductive elements or tracks based on position data provided by the gyroscopic sensor. The orientation of the holding device relative to the tongue of the user may thereby determine which conductive elements need to be activated at a given precise moment. Such information relating to the orientation and (optionally also) activation of a particular conductive element may be processed by means of the position control unit based on signals from the gyroscopic sensor.

[0051] During operation of the holding device, the conductive element of the multi-terminal ring connector can be activated in a manner perpendicular to the user's tongue. As a result, the upper surface of the tongue can encounter the first electrode of the aerosol generating article, while the lower surface of the tongue can contact the second electrode of the aerosol generating article. At the same time, the heating element in the holding device can heat the aerosol generating article, for example, through an induction heating process of an electromagnetic field generated by an induction coil. An aerosol is generated that the user can receive through inhalation. During this inhalation, the user can also receive a certain amount of preferred alternating potential on the tongue through the electrodes. The combination of aerosol inhalation and potential can result in an artificial taste experience in the overall smoking experience.

[0052] The holding device may be connected to the main unit. The main unit may include a power source and / or a control unit. The power source may be a rechargeable battery with a charging port. The main unit may also have a heat dissipation housing made of a thermally conductive material that allows heat energy to dissipate from the temperature control element to the ambient air.

[0053] The main unit may be a separate component distinct from the holding device and reversibly connected to the holding device. The main unit and the holding device may be stackable relative to each other and may be connected by means of a screw connection, a snap-fit ​​connection, a friction connection, a magnetic connection, etc. Alternatively, the main unit and the holding device may be a single piece. The housing of the holding device and the housing of the main unit are then the same integral component.

[0054] In an embodiment, the main unit may include at least a button, a wheel, a toggle switch, a sensor and / or other user input device. In the following, a button is used as an example. The button can serve as an interface for the user to operate the holding device and adjust the stimulation. The button can be configured to activate the heating element for aerosol generation. The same or another button can be configured to activate the potential between the first electrical part and the second electrical part. As a result, the button can allow the aerosol generator and / or the artificial taste stimulation to be turned on and off.

[0055] In an embodiment, the button may be further configured to control the amount of electrical potential between the first electrical portion and the second electrical portion. As a result, the button may control the intensity of the electrical stimulation and thereby allow the intensity of the taste simulation to be adjusted.

[0056] In summary, the holding device of the present invention for aerosol generating articles can allow a customizable electro-stimulation experience by adjusting the taste intensity. The taste intensity can be controlled by the user and / or by means of presets based on tracking historical usage of the holding device. The holding device of the present invention can further allow appropriate temperature of the area in contact with the user by means of temperature control of the electrodes via a heat transfer element that utilizes the housing of the holding device to dissipate heat.

[0057] According to another aspect of the present disclosure, there is provided a holder comprising an aerosol-generating article as described above and a holding device as described above.The aerosol-generating article is partially inserted into a receiving portion of the holding device.

[0058] The holder may be understood as a tobacco heating system receiving an aerosol-generating article as a rod-shaped article.The aerosol-generating article comprises an aerosol-generating substrate, which may be solid tobacco or other suitable substrate.

[0059] The holder of the present invention can allow the taste to be improved by electrical stimulation during consumption. It can generate and manage electrical signals for electrical taste stimulation. The electrical signals are conducted to the user's mouth and tongue via the aerosol generating article. The aerosol generating article has a device for conducting electrical signals to the mouth and tongue, as well as a device for electrical stimulation and (optionally) thermal stimulation of the taste buds on the user's tongue or lips. When the user experience begins, the aerosol generating article transmits a specific electrical potential and optionally a temperature to the taste buds of the tongue to provide additional taste perceptions, such as salty, sour or bitter. The holder of the present invention can optionally use a preferably alternating potential of varying frequency or direct current or both within a controlled temperature range for taste stimulation.

[0060] The air flow through the holder may be understood as: the aerosol generating article may be partially inserted into the receiving part of the holding device. Air may be drawn into the holding device by the action of a user sucking on the mouthpiece of the aerosol generating article. Air may in particular be drawn into the holding device through at least the inlet. The air inlet may be in fluid communication with the airflow channel. As a result, the air drawn into the holding device may pass through at least one air channel. The inhaled air may enter the aerosol-forming substrate at the distal end of the aerosol generating article. The inhaled air may travel through the aerosol-forming substrate which may be heated to generate an aerosol, and then reach the mouthpiece of the aerosol generating article, and return to the user.

[0061] According to another aspect of the present disclosure, a method for electrically stimulating a user's taste buds is also provided. The method for electrically stimulating a user's taste buds comprises the following steps, not necessarily in this order:

[0062] - providing an aerosol-generating article as described above, and

[0063] - activating a power source and thereby providing a potential between the first electrode and the second electrode of the aerosol article to stimulate taste buds on the tongue of a user.

[0064] The method of the present invention for electrically stimulating a user's taste buds may allow for better performance in terms of aroma and flavor compared to conventional aerosol generation methods. Aroma and flavor aspects are improved because the aerosol-generating article of the present invention may provide a means for electrically stimulating a user's taste sense during consumption. It has two electrodes that may have a connection to the user's mouth and thereby may stimulate the taste buds of the tongue via electrical signals.

[0065] In use, the user can insert the aerosol generating article into the holding device through the opening on the top side. The aerosol generating article can make physical and electrical contact with the holding device using electrical terminals and conductive elements. These physical contacts introduce current into the first electrode and the second electrode at the aerosol generating article to generate artificial taste stimulation for the user during the user experience. The electrical terminals, conductive elements and electrodes allow the potential generated by the power supply across the aerosol generating article to be electrically conducted to the user's tongue. The aerosol generating article can also make physical and electrical contact with a heating element provided in the holding device to generate an aerosol from the aerosol generating article. The user can activate the system by at least pressing a button, and can generate an aerosol from the aerosol generating article in combination with the artificial taste stimulation from the electrodes for the user experience.

[0135] Figure 1a The holder 1 is shown with an aerosol-generating article 400 partially inserted. Figure 1b A holder 1 is shown, which comprises a holding device 300 for an aerosol generating article 400 and a main unit 100. The aerosol generating article 400 is separated from the holding device 300. The holder 1 comprises a combination of the aerosol generating article 400 and the holding device 300. The holding device 300 is a tobacco heating system that receives the aerosol generating article 400. The aerosol generating article 400 is a strip-shaped article comprising an aerosol generating substrate, which may be tobacco. Details of the aerosol generating article 400 can be seen in Figures 4 and 5.

[0136] The holding device 300 is here reversibly connected to the main unit 100. The main unit 100 has a housing 130, preferably made of a heat-conductive material. The main unit 100 contains and includes a power source (not shown here) and a control unit 110, which supplies power to the heating element of the aerosol-generating article 400 and controls the heating element to generate an aerosol to be inhaled. The power source and control unit 110 further supplies and controls the potential between the first electrode and the second electrode of the aerosol-generating article 400 for artificial taste stimulation.

[0137] The main unit 100 here comprises a button 120. The button 120 acts as an interface for a user to activate the heating element for aerosol generation by the aerosol generating article 400. The button 120 may also be used to activate and control the amount of electrical potential between the first and second electrodes of the aerosol generating article 400 for artificial taste stimulation.

[0138] Figure 2is a schematic cross-section of a holder 1 with a partially inserted aerosol-generating article 400. The holder 1 comprises a holding device 300 for an aerosol-generating article 400 and a main unit 100 (not shown here). Figure 3 is a schematic end view of the holding device 300 . Figure 2 and Figure 3 A schematic representation of airflow through the front or proximal end of the holding device 300 is shown. The aerosol-generating article 400 is received within the receiving portion 330 of the holding device 300. Air is drawn into the holding device 300 by the action of a user drawing on the mouthpiece 210 of the aerosol-generating article 400. Air is drawn in through the inlet 162 in the holding device 300. The air drawn into the holding device 300 passes through the air passage 164 surrounding the outside of the receiving portion 330. The inhaled air enters the aerosol-forming substrate 470 at the distal end of the aerosol-generating article 400. The inhaled air travels through the aerosol-forming substrate 470, entrains the aerosol, and then travels to the mouthpiece 210 of the aerosol-generating article 400. The air inlet 162 is at Figure 2 There are a plurality of inlets 162 spaced apart around the circumference of the holding device 300. The inlets 162 are in fluid communication with an airflow channel 164 around the receiving portion 330. Figure 2 The inlet 162 is circular, but may be of any shape. The size and number of the inlet 162 may be selected by the designer and may be selected to provide a desired resistance to suction through the device.

[0139] Figure 4a yes Figure 1b A cross section of the device shown in FIG. Figure 4b yes Figure 1a A cross section of the device shown in FIG. Figure 4a A holding device 300 according to the present disclosure is shown having a tubular receiving portion 330 for an aerosol-generating article 400. Figure 4a , the receiving portion 330 is empty. Figure 4b In the embodiment of the present invention, the aerosol-generating article 400 is partially inserted into the receiving portion 330. The holding device 300 comprises a heating element 370 arranged around the receiving portion 330 for heating the aerosol-generating article 400 to generate an aerosol.

[0140] The holding device 300 includes a first electrical portion 310 and a second electrical portion 320. The first electrical portion 310 and the second electrical portion 320 are arranged in a receiving portion 330. The first electrical portion 310 and the second electrical portion 320 are electrically connected to a power source (not shown).

[0141] When the aerosol-generating article 400 is inserted into the receiving portion 330 (see Figure 4b), the first electrical portion 310 and the second electrical portion 320 of the receiving portion 330 are in electrical contact with the first electrical terminal 410 and the second electrical terminal 420 of the aerosol generating article 400. The first electrical terminal 410 and the second electrical terminal 420 are in contact with and thus electrically connected to the first conductive element 430 and the second conductive element 440 extending along a portion of the aerosol generating article 400 in the longitudinal direction L of the aerosol generating article 400. The first conductive element 430 and the second conductive element 440 are in contact with and thus electrically connected to the first electrode 450 and the second electrode 460 of the aerosol generating article 400. As a result, the first electrode 450 and the second electrode 460 of the aerosol generating article 400 are electrically connected to a power source (not shown).

[0142] The holding device 300 comprises two temperature control elements 350, 360. The temperature control elements 350, 360 may be thermoelectric coolers. The temperature control elements 350, 360 are arranged at the receiving portion 330, behind and partially in contact with the first and second electrical parts 310, 320 of the holding device 300. The temperature control elements 350, 360 control the heat transfer between the environment, the housing 130 of the holding device 300, the first and second electrical parts 310, 320 of the holding device 300, the first and second electrical terminals 410, 420 of the aerosol generating article 400, the first and second conductive elements 430, 440 of the aerosol generating article 400, and the first and second electrodes 450, 460 of the aerosol generating article 400. It thereby controls the temperature of the first and second electrodes 450, 460 touched by the user. They may control a temperature between 20 and 35 degrees Celsius. The temperature control elements 350, 360 may be used to heat and provide thermal stimulation to the user, and / or cool to avoid uncomfortable thermal sensations at the user's tongue and / or lips.

[0143] Figure 5a and 5b Two different embodiments of an aerosol-generating article 400 according to the present disclosure are shown. In both cases, the aerosol-generating article 400 comprises an aerosol-forming substrate 470, a first electrode 450 and a second electrode 460. The first electrode 450 is at a first position of the aerosol-forming substrate 470 to provide a first electrical contact to a user. The second electrode 460 is at a second position at the front face FF of the aerosol-forming substrate 470 to provide a second electrical contact to a user. The front face FF of the aerosol-generating article 400 may be understood as the end face at the mouth end of the aerosol-generating article 400.

[0144] The second position is different from the first position. The aerosol-generating article 400 enables a potential to be provided between the first electrode 450 and the second electrode 460 to induce a potential difference between a portion of the tongue and another portion of the mouth. The potential difference can stimulate the taste buds of the tongue, giving the tongue an artificial taste to improve the user's flavor perception.

[0145] like Figure 5a As shown in FIG. 4 , the first electrode 450 and the second electrode 460 are at the front face FF of the aerosol-generating article 400. The first electrode 450 and the second electrode 460 together form a cover around the front face FF and a portion of the lateral surface LF of the aerosol-generating article 400. The front face FF may be accessible to the tongue of the user, and in particular to the tip of the tongue. This means that, in use, the two electrodes 450, 460 at the front face FF may be in a position where they are touched by the tongue and its taste buds.

[0146] like Figure 5b As shown in FIG. 4 , the first electrode 450 is on the lateral surface LF of the aerosol-generating article 400 and the second electrode 460 is on the front face FF of the aerosol-generating article 400. The lateral surface LF of the aerosol-generating article 400 may be understood as an outer, circumferential or peripheral surface of the aerosol-generating article 400, which extends along the longitudinal direction of the aerosol-generating article 400. The first electrode 450 surrounds a portion of the lateral surface of the aerosol-generating article 400 like a ring. When the first electrode 450 is on the lateral surface LF of the aerosol-generating article 400, it may be accessible to the tongue of a user and in particular to the central area on the tongue. This means that in use, the first electrode 450 may be touched by the central part of the tongue, which is different from and "behind" the tip of the tongue. When the first electrode 450 is on the lateral surface LF of the aerosol-generating article 400, the first electrode is also accessible to the lips, and in particular the lower lip, upper lip or both lips of the user. This means that the first electrode 450 can be touched by at least one lip of a user when in use.

[0147] Figures 6a to 6e 7a to 7e show two different embodiments of aerosol-generating articles 400 according to the present disclosure in different viewing angles. Figure 6a Shows an exploded view, Figure 6b A side view is shown. Figure 6c A top view is shown. Figure 6d A bottom view is shown, and Figure 6e Another side view is shown, with the internal components marked by dashed lines. Similarly, Figure 7a Shows an exploded view, Figure 7b A side view is shown. Figure 7c A top view is shown. Figure 7d A bottom view is shown, and Figure 7eAnother side view is shown, with internal components marked by dashed lines. Figures 6a to 6e and Figures 7a to 7e The arrangement of the electrodes 450 and 460 is different from Figure 5a and 5b In the difference. Figures 6a to 6e as well as Figures 7a to 7e In the embodiment of the present invention, the aerosol-generating article 400 comprises an aerosol-forming substrate 470 , a first tipping paper 401 and a second tipping paper 402 . Figures 6a to 6e and Figures 7a to 7e It shows how an aerosol-forming substrate 470 may be wrapped in tipping papers 401 , 402:

[0148] The first electrical terminal 410 and the second electrical terminal 420 are arranged in the first tipping paper 401. The first electrode 450 and the second electrode 460 are also arranged in the first tipping paper 401. The heating element (here, for example, a strip-shaped susceptor 480) is also arranged in the first tipping paper 401.

[0149] The first conductive element 430 and the second conductive element 440 are arranged on the second tipping paper 402 .

[0150] The first tipping paper 401 and the second tipping paper 402 may be wrapped together in an overlapping manner so that the first electrical terminal 410 electrically contacts the first conductive element 430, and the second electrical terminal 420 electrically contacts the second conductive element 440. This means that the two tipping papers 401, 402 may be placed in an overlapping manner so that the first tipping paper 401 completes electrical connection with the second tipping paper 402 in a manner so that the electrical terminals 410, 420, the conductive elements 430, 440 and the electrodes 450, 460 may make physical and electrical contact.

[0151] Figure 8 Another embodiment of a holder 1 according to the present disclosure is schematically and exemplarily shown in cross section. The holder 1 comprises a holding device 300 for an aerosol-generating article 400 and a primary unit 100. The aerosol-generating article 400 is partially inserted into the opening 180 of the holding device 300. The holding device 300 is reversibly connected to the primary unit 100.

[0152] The main unit 100 comprises a power source 112 having a charging port 105 to supply power to a heating element of the aerosol generating article 400 to generate an aerosol to be inhaled. The heating element here comprises an induction coil 190 and a susceptor 165. The power source 112 further supplies a potential between a first electrode 450 and a second electrode 460 of the aerosol generating article 400 for artificial taste stimulation.

[0153] The holding device 300 includes an air inlet opening 162 which acts as an opening for the availability of ambient air for aerosol inhalation by a user, cools the exterior of the device, and prevents overheating of the interior of the device. The holding device 300 includes a multi-terminal ring connector module 170 disposed within the holding device 300 .

[0154] Figures 9a to 9c Schematically and exemplarily, the following figure ( Figure 9a ), side view ( Figure 9b ) and the previous view ( Fig.9c ) shows an embodiment of a multi-terminal ring connector module 170. The multi-terminal ring connector module 170 includes a plurality of segments 172, 176 arranged together with a cladding 178. Figure 9b , the plurality of segments 172, 176 form a plurality of conductive elements 430, 440 or tracks. At least two of these conductive elements 430, 440 may be electrically connected to a first electrode 450 and a second electrode 460 of the aerosol generating article 400 to provide a potential to a user from the power source 112. In particular, the first segment 172 in cross section forms a first conductive element 430 extending in the longitudinal direction and electrically connected to the first electrode 450. The second segment 176 in cross section forms a second conductive element 440 extending in the longitudinal direction and electrically connected to the second electrode 460.

[0155] return Figure 8 , the holding device 300 includes a gyroscopic sensor 117 and a position control unit 115. The position control unit 115 selects a first conductive element 430 and a second conductive element 440 from a plurality of conductive elements or tracks based on position data provided by the gyroscopic sensor 117. The orientation of the holding device 300 relative to the user's tongue can thereby determine which conductive elements 430, 440 need to be activated at a given moment.

[0156] In operation, the holding device 300 requires the user to insert the aerosol-generating article 400 into the holding device 300. The aerosol-generating article 400 passes through the opening 180 toward the interior of the holding device 300 so that the susceptor 165 surrounds the aerosol-generating substrate. At the same time, the conductive elements 430, 440 on the aerosol-generating article 400 make physical contact with the multi-terminal ring connector module 170.

[0157] Multi-terminal connector modules Figures 9a to 9c170. The conductive elements 430, 440 make physical contact with the segments 172, 176 of the multi-terminal ring connector module 170. These conductive elements 430, 440 allow the potential generated by the power source 112 to be conducted across the aerosol generating article 400 to the user's tongue. The orientation of the holding device 300 relative to the user's tongue determines which conductive elements 430, 440 must be activated at a given moment. This information about the orientation and activation of the preferred conductive elements 430, 440 is processed inside the position control unit 115 based on the signals from the gyro sensor 117.

[0158] During operation of the retaining device 300, two conductive segments 172, 176 of the multi-terminal ring connector 170 are activated, which are arranged at relative positions on the circumference of the multi-terminal ring connector 170 to touch relative positions at the user's mouth ( Figures 9a to 9c For example, the upper surface of the tongue meets the first conductive segment, while the upper lip contacts the second conductive segment arranged at a position opposite to the first conductive segment on the circumference of the multi-terminal ring connector 170.

[0159] At the same time, the susceptor 165 in the holding device 300 is heated by the induction heating process from the electromagnetic field generated by the induction coil 190. This heating of the susceptor 165 heats the aerosol generating substrate, resulting in aerosol generation, which the user can receive by inhalation. During this inhalation, the user can also receive a certain amount of electrical potential on the tongue through the electrodes 450, 460. The combination of aerosol inhalation and electrical potential can result in a taste experience that combines the aerosol generated by the aerosol generating substrate and the flavor enhancement from the electrical stimulation of the tongue in the overall smoking experience.

Between the aerosol-forming substrate end 290 and the filter segment end 215, the tipping paper 401 on the aerosol-generating article 400 has parallel conductive elements 430, 440. At the filter segment end 215, the tipping paper 401 extends forward relative to the filter segment 210. The tipping paper 401 is folded at the filter segment end 215 that touches the user's tongue to keep the surface above the conductive elements 430, 440 at the filter segment end 215 smooth to prevent trauma on the user's tongue or lips. "F" represents the length of the folded area, "D" represents the diameter of the aerosol generating article 400, and "L" represents the length of the aerosol generating article 400.

The main unit 100 comprises a power source 112 having a charging port 105. The aerosol-generating article 400 is partially inserted into the opening 180 of the holding device 300 and is penetrated by the heating element 167, which heats the aerosol-generating article 400 to generate an aerosol. Figure 8 Unlike the holder 1 shown in the embodiment of FIG. 1 , in which heating is achieved using an induction process, resistive heating is used here. The holding device 300 may also optionally include the following: Figure 8 The gyroscopic sensor 117, the position control unit 115 and the multi-terminal ring connector module 170 in the embodiment of the present invention are shown in FIG. The position control unit 115 selects the first conductive element 430 and the second conductive element 440 from a plurality of conductive elements or tracks based on the position data provided by the gyroscopic sensor 117. The orientation of the holding device 300 relative to the user's tongue can thereby determine which conductive elements 430, 440 need to be activated at a given moment.
