Description

Technical Field

[0001] The present invention relates to an aerosol-generating system comprising a flavor element. Background Art

[0002] There are known aerosol-generating devices for generating an inhalable vapor. Such devices can heat an aerosol-forming substrate of an aerosol-generating article to a temperature at which one or more components of the aerosol-forming substrate are volatilized without burning the aerosol-forming substrate. To volatilize the aerosol-forming substrate, a heating element can be provided. The inhalable vapor can be delivered to a consumer through an air flow channel and an air outlet. The aerosol-generating device can include a flavor element to deliver a flavor to the consumer. However, the flavor element is typically permanently fixed to the device. Thus, once the flavor delivered by the flavor element is completely consumed, the device may become unavailable or at least provide a less satisfactory consumption experience. Once the flavor is completely consumed, the consumer needs to purchase a new device and thus faces an increased cost of the consumption experience. In addition, the fixed flavor element limits the consumer's ability to select and tune the delivered flavor.

[0003] Furthermore, the flavor provided by the flavor element is typically in fluid communication with the aerosol delivery components of the device. Flavoring compounds are typically included in the aerosol-generating article. However, there is a risk that the flavoring compounds are lost by evaporation from the article during the typically heat-intensive production of the aerosol-generating article. This also results in a certain degree of variation in the delivered flavor between different production batches of the aerosol-generating article. In addition, there is a risk of flavor degradation during the production of the aerosol-generating article. Additionally, the consumer is limited in the selection and tuning of the delivered flavor. Summary of the Invention

[0004] There is a desire for an aerosol-generating device in which the flavor element can be installed in a faster and easier manner. There is a desire for an aerosol-generating device in which the flavor element can be used in a universal manner. There is a desire for an aerosol-generating device in which the delivered flavor can be flexibly and easily selected and tuned. There is a desire to provide an aerosol-generating device that provides a rich sensory experience. There is a desire to provide an aerosol-generating device that provides a substantially constant flavor output. There is a desire for an aerosol-generating device that provides an improved consumption experience to the user. There is a desire for an aerosol-generating device that provides a cost-effective consumption experience to the consumer. There is a desire for an aerosol-generating device that enables improved production of the flavored component.

[0005] According to the present invention, an aerosol generating system is provided. The aerosol generating system includes an aerosol generating device, which includes a housing and an airflow passage for delivering an aerosol. The airflow passage is arranged within the housing. The aerosol generating system includes an aerosol generating article. The aerosol generating system includes at least one flavor element. The flavor element is configured to be removably mounted at the housing of the aerosol generating device. The flavor element is configured to release a flavorant. The flavor element is configured such that when the flavor element is mounted at the housing of the aerosol generating device, it is not in fluid communication with the airflow passage, so that the flavorant is released from the flavor element separately from the aerosol in the airflow passage.

[0006] The aerosol generating article may include an aerosol-forming substrate. The aerosol-forming substrate may be configured to be capable of releasing volatile compounds that can form an aerosol. The aerosol generating device may be configured to deliver the aerosol to a consumer, preferably into the consumer's mouth, via the airflow passage. The aerosol generating system may be configured to release the flavorant separately from the aerosol formed by the aerosol-forming substrate. The aerosol generating system may be configured to release the flavorant independently of the aerosol formed by the aerosol-forming substrate. The aerosol generating system may be configured to release the flavorant in addition to the aerosol formed by the aerosol-forming substrate. The aerosol generating system may be configured to release the flavorant as an additional consumption experience for the aerosol. The aerosol generating system may be configured such that the aerosol and the flavorant do not mix with each other within the airflow passage. The aerosol generating device may be configured to heat the aerosol-forming substrate to evaporate at least a portion of the aerosol-forming substrate.

[0007] The flavor element may be configured to direct the released flavorant to the nose, preferably to the consumer's nostrils. The flavor element may be configured to release the flavorant towards the nose, preferably the consumer's nostrils. The flavor element may be configured to release the flavorant directly to the nose, preferably to the consumer's nostrils. The flavor element may be configured to release the flavorant through the nose to stimulate the trigeminal nerve.

[0008] The flavorant released by the flavor element may enrich the consumer's sensory experience. The flavorant released by the flavor element may provide the consumer with an additional consumption experience in addition to the consumption experience of consuming the aerosol. The released flavorant may stimulate the trigeminal nerve by passing through the nose.

[0009] Since the flavor element is configured to be removably mounted at the housing, the flavor element is easy to install. The flavor element gives the consumer the opportunity to comfortably obtain a further consumption experience. Since the flavor element is configured to be removably mounted at the housing, the flavor element can be easily replaced. When the previous flavor element has been damaged or completely consumed, the user can easily install a new flavor element. The flavor element can enable the consumer to adjust the consumption experience brought by the aerosol generating system according to the consumer's preferences. If a different consumption experience is desired, the consumer can replace the flavor element. Since the flavor element is configured to be removably mounted at the housing, the flavor element can be used with different types of aerosol generating devices. Since the flavor element is configured to be removably mounted at the housing, the flavor element can be used with different types of existing aerosol generating devices without modifying or substantially modifying such existing devices. The flavor element can achieve multifunctional use.

[0010] In addition, by providing a flavor element configured not to be in fluid communication with the airflow path, the production of the aerosol generating system can be made easier and more versatile. Loss of flavorants and flavor sources during production can be avoided. The risk of deterioration of flavorants and flavor sources during production can be reduced. Additionally, flavorants and flavor sources can be more easily adapted to external requirements such as user preferences and legal requirements. The additional sensory experience provided by the flavorant can be delivered to the consumer separately and independently of the consumption experience provided by the aerosol.

[0119] In any aspect of the present disclosure, the heating element may comprise a resistive material. Suitable resistive materials include, but are not limited to: semiconductors such as doped ceramics, "conductive" ceramics (such as, for example, molybdenum disilicide), carbon, graphite, metals, metal alloys, and composite materials made of ceramic materials and metal materials. Such composite materials may include doped or undoped ceramics. Examples of suitable doped ceramics include doped silicon carbide. Examples of suitable metals include titanium, zirconium, tantalum, platinum, gold, and silver. Examples of suitable metal alloys include stainless steel, nickel-containing alloys, cobalt-containing alloys, chromium-containing alloys, aluminum-containing alloys, titanium-containing alloys, zirconium-containing alloys, hafnium-containing alloys, niobium-containing alloys, molybdenum-containing alloys, tantalum-containing alloys, tungsten-containing alloys, tin-containing alloys, gallium-containing alloys, manganese-containing alloys, gold-containing alloys, iron-containing alloys, and superalloys based on nickel, iron, cobalt, stainless steel, and iron-manganese-aluminum alloys. In the composite material, the resistive material may optionally be embedded in, encapsulated by, or coated with an insulating material or vice versa, depending on the kinetics of energy transfer and the desired external physical and chemical properties.

[0120] As described, in any aspect of the present disclosure, the heating element may be part of an aerosol-generating device. The aerosol-generating device may include an internal heating element, an external heating element, or both an internal heating element and an external heating element, where "internal" and "external" are with respect to the aerosol-forming substrate. The internal heating element may take any suitable form. For example, the internal heating element may take the form of a heating blade. Alternatively, the internal heater may take the form of a sleeve or substrate having different conductive portions, or a resistive metal tube. Alternatively, the internal heating element may be one or more heating pins or rods extending through the center of the aerosol-forming substrate. Other alternatives include heating wires or filaments, such as, for example, Ni-Cr (nickel-chromium), platinum, tungsten, or alloy wires or heating plates. Optionally, the internal heating element may be deposited in or on a rigid carrier material. In one such embodiment, the resistive heating element may be formed using a metal having a defined relationship between temperature and resistivity. In such an exemplary device, the metal may be formed as tracks on a suitable insulating material (such as a ceramic material) and then sandwiched between another insulating material (such as glass). The heater formed in this way may be used to both heat and monitor the temperature of the heating element during operation.

[0121] The external heating element can be in any suitable form. For example, the external heating element can be in the form of one or more flexible heating foils on a dielectric substrate (such as, polyimide). The flexible heating foil can be shaped to conform to the perimeter of the substrate receiving cavity. Alternatively, the external heating element can be in the form of a metal grid or multiple metal grids, a flexible printed circuit board, a molded interconnect device (MID), a ceramic heater, a flexible carbon fiber heater, or can be formed on a suitable shaped substrate using coating techniques (such as, plasma vapor deposition). The external heating element can also be formed using a metal having a defined relationship between temperature and resistivity. In such an exemplary device, the metal can be formed as tracks between two layers of suitable insulating material. The external heating element formed in this way can be used to both heat and monitor the temperature of the external heating element during operation.

[0122] As an alternative to the resistive heating element, the heating element can be configured as an inductive heating element. The inductive heating element can include an induction coil and a susceptor. Generally, the susceptor is a material that can generate heat when penetrated by an alternating magnetic field. When located in an alternating magnetic field. If the susceptor is conductive, eddy currents are typically induced by the alternating magnetic field. If the susceptor is magnetic, another effect that typically contributes to heating is generally referred to as hysteresis loss. Hysteresis loss is mainly due to the movement of magnetic domain blocks within the susceptor, as the magnetic orientation of these magnetic domain blocks will align with the alternating magnetic induction field. Another effect that contributes to hysteresis loss is when the magnetic domains will grow or shrink within the susceptor. Generally, all these changes in the susceptor that occur at the nanoscale or below are referred to as "hysteresis loss" because they generate heat in the susceptor. Thus, if the susceptor is both magnetic and conductive, both hysteresis loss and eddy current generation will contribute to the heating of the susceptor. If the susceptor is magnetic, but not conductive, hysteresis loss will be the only means of heating the susceptor when penetrated by an alternating magnetic field. According to the present invention, the susceptor can be conductive or magnetic, or both conductive and magnetic. The susceptor is heated by an alternating magnetic field generated by one or more induction coils, and the susceptor then transfers the heat to the aerosol-forming substrate such that an aerosol is formed. The heat transfer can be mainly by heat conduction. Such heat transfer is optimal if the susceptor is in close thermal contact with the aerosol-forming substrate.

[0123] As used herein, the term "aerosol-generating article" refers to an article comprising an aerosol-forming substrate capable of releasing volatile compounds that can form an aerosol. For example, the aerosol-generating article can generate an aerosol that can be directly inhaled by a user into the user's lungs through the user's mouth. The aerosol-generating article can be disposable.

[0124] As used herein, the term "aerosol - forming substrate" refers to a substrate capable of releasing one or more volatile compounds that can form an aerosol.

Examples of suitable aerosol - forming agents are glycerol and propylene glycol.

[0126] The aerosol - generating substrate preferably includes: homogenized tobacco material, aerosol - forming agent, and water. Providing homogenized tobacco material can improve aerosol generation, nicotine content, and flavor characteristics of the aerosol generated during heating of the aerosol - generating article. Specifically, the process of manufacturing homogenized tobacco involves grinding tobacco leaves, which more effectively achieves the release of nicotine and flavors upon heating.

[0127] The aerosol - forming substrate can be a liquid. The aerosol - generating article can include a container, cartridge, or reservoir that holds the liquid aerosol - forming substrate. The mouthpiece can include a container, cartridge, or reservoir that holds the liquid aerosol - forming substrate.

[0161] Figure 1 shows the aerosol generating system 100 of the present invention. The system includes an aerosol generating device 102, a flavor element 104 and an aerosol generating article 106. The flavor element 104 is mounted on the device 102.

[0162] The flavor element 104 includes a receiving element 108. The receiving element 108 includes an adsorbent material 110. The adsorbent material 110 is inserted into a chamber of the receiving element 108. The adsorbent material 110 includes a flavor source. The receiving element 108 includes a flavor outlet 112. The flavor element 104 further includes a gripping element 114. The gripping element 114 is clamped between the aerosol-generating device 102 and the receiving element 108. The gripping element 114 improves the retention of the flavor element 104 on the aerosol-generating device 102.

[0163] The aerosol-generating device includes a housing 116. The aerosol-generating device is inserted into an opening of the receiving element 108.

[0164] The aerosol-generating system further includes an aerosol-generating article 106 that includes an aerosol-forming substrate. The aerosol-generating article 106 is inserted into a cavity of the aerosol-generating device.

[0165] In use, the consumer draws on the proximal end 118 of the aerosol-generating article 106. When the user draws on the aerosol-generating article 106, a negative pressure is generated. Ambient air is drawn into the aerosol-generating device 102 and is drawn towards the user through an air flow channel. A heating element (not shown) of the aerosol-generating device 102 is arranged to heat the aerosol-forming substrate to a temperature that is below the combustion temperature of the aerosol-forming substrate but at or above the temperature at which one or more volatile compounds of the aerosol-forming substrate are released to form an inhalable aerosol. The aerosol is drawn into the consumer's mouth at the proximal end 118 of the aerosol-generating article 106.

[0166] In addition, a flavor is generated by volatilizing at least a portion of the flavor source of the adsorbent material 110. The flavor is released into the surrounding environment through the flavor outlet 112 of the flavor element 104.

[0167] When the aerosol-generating article 106 is inserted into the consumer's mouth, the flavor element 104 is located near the consumer's nose. The released flavor is delivered to the consumer's nose. The flavor stimulates the receptors in the nose. In this way, in addition to the experience provided by the aerosol consumed through the consumer's mouth, the flavor also provides a sensory experience to the consumer.

[0168] The release of the flavor is separate from the release of the aerosol. The flavor is separated from the aerosol at least by the housing 116 of the device 102. Fluid communication between the flavor element 104 and the interior of the device 102 is at least prevented by the housing of the device 116.

[0169] The consumer can select an installation position along the longitudinal axis 119 of the device 102.

[0170] Figure 2 is shown similar to Figure 1A more detailed view of the compartment of the flavor element 104 of the flavor element 104. Figure 2 A shows two views of the gripping element 114. Figure 2 The left - hand side of A shows the gripping element 114 in an open configuration. Figure 2 The right - hand side of A shows the gripping element in a closed configuration.

[0171] The gripping element 114 is configured as a strip. The gripping element 114 includes a first surface 120. The first surface 120 is configured to be smooth. On the opposite side of the strip, the gripping element 114 includes a second surface 121. The second surface 121 is configured to be matte. The second surface 121 may have a surface roughness greater than that of the first surface 120.

[0172] The gripping element 114 is transferred from the open configuration to the closed configuration by at least partially rolling up the gripping element 114 to form a loop. Thus, the smooth surface is located on the inside of the loop, and the matte surface is located on the outside of the loop. The gripping element 114 can be wrapped around the aerosol - generating device 102 to mount the gripping element 114 on the device 102. As shown in Figure 1 When the gripping element 114 is mounted to the device 102, it is in the closed configuration. The smooth first surface 120 contacts the surface of the housing 116 of the device 102. The matte second surface 121 faces the receiving element 108 of the flavor element 104 to improve the frictional contact between the gripping element 114 and the adsorption material 110 accommodated in the receiving element 108.
