Description

Aerosol delivery device

The present invention relates to aerosol delivery devices, aerosol delivery systems and methods for generating aerosols.

Articles such as cigarettes, cigars, etc. produce smoke by burning tobacco during use. Attempts have been made to provide alternatives to these types of cigarette burning products by creating products that release the compounds without burning them. Devices are known for heating a smokable material to volatilize at least one component of the smokable material and form an aerosol that can be inhaled, typically with or without burning the smokable material. These devices are sometimes described as “heat-not-burn” devices or “tobacco heating products (THP)” or “tobacco heating devices.” Various other arrangements are known for volatilizing at least one component of a smokable material.

The material may be, for example, a combination of tobacco, other non-tobacco products or a blended mix, which may or may not contain nicotine.

An aerosol-generating material is a material that is capable of generating an aerosol, for example, when energized, irradiated or heated in any other way. Aerosol-generating materials may, for example, be in the form of solids, liquids or gels, which may or may not contain active substances and/or flavoring agents.

The aerosol-generating material may include one or more active substances and/or flavors, one or more aerosol former materials, and optionally one or more other functional materials.

Devices are known that heat an aerosol-generating material to volatilize at least one component of the aerosol-generating material and form an aerosol that can be inhaled, typically with or without burning the aerosol-generating material. Such devices are sometimes referred to as “aerosol generating devices”, “aerosol providing devices”, “heat-not-burn devices”, “tobacco heating products”, “tobacco heating products devices”, “tobacco heating devices”, etc. It is explained as In some embodiments, the aerosol delivery device is a tobacco heating product. Non-liquid aerosol generating materials for use with tobacco heating products include tobacco.

E-cigarette devices are also known, comprising aerosol delivery devices that vaporize aerosol-generating material in liquid form that may or may not contain nicotine. The aerosol-generating material may be provided in the form of, or as part of, a rod, cartridge, or cassette that can be inserted into the device. A heater for heating and volatilizing the aerosol-generating material may be provided as a “permanent” part of the device.

A non-flammable aerosol delivery system may include a hybrid system for generating an aerosol using a combination of aerosol-generating materials, one or more of the aerosol-generating materials being heated. Each of the aerosol-generating materials may be in solid, liquid or gel form, for example, and may or may not contain nicotine. In some embodiments, the hybrid system includes a liquid or gel aerosol-generating material and a solid aerosol-generating material. Solid aerosol generating materials may include, for example, tobacco or non-tobacco products.

The aerosol-providing device may contain an article that contains aerosol-generating material for heating and is referred to as a “smoking article.” In this context, an “article”, “aerosol-generating article” or “smoking article” refers to a component that, when in use, contains or retains aerosol-generating material, which is heated to volatilize the aerosol-generating material, and optionally other components in use. They are elements. A user may insert an article into an aerosol presentation device before the article is heated to generate an aerosol, and the user subsequently inhales the aerosol. The article may be of a predetermined or specific size, for example, configured to be placed within a heating chamber of a device sized to receive the article.

An aerosol provision device according to various embodiments includes a plurality of aerosol generators. An aerosol generator is a device configured to produce an aerosol from an aerosol generating material. In some embodiments, the aerosol generator is a heater configured to apply thermal energy to the aerosol-generating material to release one or more volatile substances from the aerosol-generating material to form an aerosol. In some embodiments, the aerosol generator is configured to generate an aerosol from an aerosol generating material without heating. For example, an aerosol generator may be configured to apply one or more of vibration, increased pressure, or electrostatic energy to the aerosol generating material.

The aerosol generator may include an induction coil. In some examples, the coil is configured to heat the at least one electrically conductive heating element, such that thermal energy can be conducted from the at least one electrically conductive heating element to the aerosol-generating material, thereby causing heating of the aerosol-generating material.

In some examples, the coil is configured to generate a variable magnetic field for penetrating the at least one heating element when in use, thereby producing inductive heating and/or magnetic hysteresis heating of the at least one heating element. In this arrangement, the or each heating element may be referred to as a “susceptor”. A coil configured to generate a variable magnetic field for penetrating the at least one electrically conductive heating element during use, thereby producing inductive heating of the at least one electrically conductive heating element, is referred to as an “induction coil” or “inductor coil”. It can be called.

In some examples, the coils are helical. In some examples, coils can surround at least a portion of a heating zone of an aerosol-providing device configured to receive aerosol-generating material. In some examples, the coils are helical coils that surround at least a portion of the heating zone.

It has been found that the induction heating units of the aerosol delivery device reach their maximum operating temperature much more quickly than the corresponding resistive heating elements. According to various embodiments, the aerosol presentation device can be configured such that one or both heating units reach their maximum operating temperature at a rate of at least 100 degrees Celsius per second. In certain embodiments, the aerosol presentation device can be configured such that one or both heating units reach a maximum operating temperature at a rate of at least 150 degrees Celsius per second.

Induction heating systems may be of interest because the magnetic field magnitude can be easily controlled by controlling the power supplied to the heating unit. Moreover, induction heating eliminates the need to provide a physical connection between the source of the changing magnetic field and the heat source, allowing greater design freedom and control over the heating profile and lower costs.

The aerosol presentation device may include a heating assembly. The heating assembly can include a first aerosol generator and a second aerosol generator. The first aerosol generator and the second aerosol generator may comprise induction heating units, and the units may be controllable independently of each other. Heating the aerosol-generating material with independent heating units can provide more precise control of the heating of the aerosol-generating material. Independently controllable heating units may also provide heat energy differently to each portion of the aerosol-generating material, resulting in different temperature profiles across portions of the aerosol-generating material.

According to various embodiments, the first and second aerosol generators may be configured to have different temperature profiles when in use. This can provide asymmetric heating of the aerosol-generating material along the longitudinal plane between the mouth end and the distal end of the aerosol-providing device when the aerosol-providing device is in use.

Alternatively, the first and second aerosol generators can be configured to have substantially identical temperature profiles when in use. This can provide symmetrical heating of the aerosol-generating material along the longitudinal plane between the mouth end and the distal end of the aerosol-providing device when the aerosol-providing device is in use.

Objects that can be inductively heated are known as susceptors. In cases where the susceptor contains a ferromagnetic material, such as iron, nickel or cobalt, heat is also generated by magnetic hysteresis losses in the susceptor, i.e. in the magnetic material as a result of the alignment of magnetic dipoles with a changing magnetic field. It can be created by various orientations of magnetic dipoles. In induction heating, compared to heating by conduction, for example, heat is generated inside the susceptor, allowing rapid heating. Moreover, no physical contact is required between the induction heater and the susceptor, allowing enhanced freedom in construction and application.

Reference may be made to the temperature of heating elements throughout this specification. The temperature of the heating element may conveniently also be referred to as the temperature of the heating unit comprising the heating element. This does not necessarily mean that the entire heating unit is at a given temperature. For example, if reference is made to the temperature of an induction heating unit, this does not necessarily mean that both the induction element and the susceptor have that temperature. Rather, in this example, the temperature of the induction heating unit corresponds to the temperature of a heating element configured in the induction heating unit. Undoubtedly, the temperature of the heating element and the temperature of the heating unit can be used interchangeably.

As used herein, “temperature profile” refers to the variation in temperature of a material over time. For example, the changing temperature of a heating element or heating unit measured at the heating element or heating unit over the duration of a smoking session may be referred to as the temperature profile of that heating element or heating unit. Heating elements or heating units provide heat to the aerosol-generating material to generate an aerosol during use. Accordingly, the temperature profile of the heating element or heating unit leads to the temperature profile of the aerosol-generating material disposed near the heating element or heating unit.

As used herein in reference to a heating element or heating unit, “operating temperature” means any temperature at which the element can heat the aerosol-generating material to generate sufficient aerosol for a satisfactory puff without burning the aerosol-generating material. Refers to element temperature. The maximum operating temperature of a heating element is the highest temperature reached by the element during a smoking session. The lowest operating temperature of a heating element refers to the lowest heating element temperature at which sufficient aerosol can be generated from the aerosol generating material by the heating element for a satisfactory puff. If there are multiple heating elements or heating units present in the aerosol presentation device, each heating element or heating unit has an associated maximum operating temperature. The maximum operating temperature of each heating element or heating unit may be the same or may be different for each heating element or heating unit.

In an aerosol-providing device according to one embodiment, each heating element or heating unit may be arranged to heat but not burn the aerosol-generating material. Although the temperature profile of each heating element or heating unit may lead to the temperature profile of each associated portion of the aerosol-generating material, the temperature profiles of the heating element or heating unit and the associated portion of the aerosol-generating material may not correspond exactly. . For example, there may be a “bleed” in the form of conduction, convection, and/or radiation of thermal energy from one part of the aerosol-generating material to another; There may be variations in conduction, convection and/or radiation of thermal energy from the heating elements or heating units to the aerosol generating material; Depending on the heat capacity of the aerosol-generating material, there may be a lag between a change in the temperature profile of the heating element or heating unit and a change in the temperature profile of the aerosol-generating material.

The aerosol presentation device may include a controller for controlling each aerosol generator present in the aerosol presentation device. The controller may include a printed circuit board (“PCB”). The controller may be configured to control the power supplied to each heating unit and control the “programmed heating profile” of each heating unit present in the aerosol presentation device. For example, the controller can be programmed to control the current supplied to the plurality of inductors to control the resulting temperature profiles of the corresponding induction heating elements or induction heating units. As between the temperature profiles of the aerosol-generating material and the heating elements/units described above, the programmed heating profile of the heating element or heating unit may, for the same reasons given above, exactly match the observed temperature profile of the heating element or heating unit. It may not respond.

The term “operating temperature” may also be used in relation to aerosol-generating materials. In this case, the term refers to any temperature of the aerosol-generating material itself at which sufficient aerosol is generated from the aerosol-generating material for a satisfactory puff. The maximum operating temperature of an aerosol-generating material is the highest temperature reached by any part of the aerosol-generating material during a smoking session. In some embodiments, the maximum operating temperature of the aerosol-generating material is greater than 200 °C, 210 °C, 220 °C, 230 °C, 240 °C, 250 °C, 260 °C, or 270 °C. In some embodiments, the maximum operating temperature of the aerosol-generating material is less than 300 °C, 290 °C, 280 °C, 270 °C, 260 °C, or 250 °C. The lowest operating temperature is the lowest temperature of the aerosol-generating material at which sufficient aerosol is generated from the material to generate sufficient aerosol for a satisfactory “puff.” In some embodiments, the lowest operating temperature of the aerosol-generating material is greater than 90 °C, 100 °C, 110 °C, 120 °C, 130 °C, 140 °C, or 150 °C. In some embodiments, the lowest operating temperature of the aerosol-generating material is less than 150°C, 140°C, 130°C, or 120°C.

The goal of various embodiments is to reduce the amount of time it takes for an aerosol delivery device to be ready for use and, more generally, to improve the user's inhalation experience. Surprisingly, reducing the time it takes for a heating element or heating unit to reach operating temperature can at least partially alleviate the "hot puff," a phenomenon that occurs when the generated aerosol contains a high water content. It turned out that it was possible. Accordingly, aerosol delivery devices according to various embodiments have better organoleptic properties than aerosols provided by conventional aerosol delivery devices that do not include heating units that quickly reach their maximum operating temperature. An inhalable aerosol having these can be provided to consumers.

In some embodiments, the aerosol delivery device is configured such that at least one heating element within the device reaches the maximum operating temperature within 20 seconds, and wherein the at least one heating unit is configured to heat at least 1 second, 2 seconds, 3 seconds, 4 seconds, 5 seconds. The first temperature maintained for seconds, 10 seconds, or 20 seconds is the maximum operating temperature. That is, in these embodiments, the heating unit is not maintained at a temperature other than the maximum operating temperature before reaching the maximum operating temperature. In some embodiments, the at least one heating unit reaches its maximum operating temperature within a given period of time from ambient temperature.

An aerosol delivery device may be configured to operate as described herein. An aerosol delivery device may be configured, at least in part, to operate in this manner by a controller that may be programmed to operate the device in one or more different modes. Accordingly, references herein to the configuration of an aerosol-providing device or components thereof may refer to a controller being programmed to operate the aerosol-providing device disclosed herein, among other features (e.g., a spatial arrangement of heating units). .

Aerosol-generating articles for aerosol-providing devices (such as tobacco heating products) typically retain more water and/or aerosol-generating agent than combustible smoking articles to facilitate aerosol formation during use. This higher water and/or aerosol generating agent content may increase the risk of condensate collection within the aerosol presentation device during use, particularly in locations remote from the heating unit(s). This problem may be greater in aerosol-providing devices with sealed heating chambers, and especially in aerosol-providing devices with external heaters, than in those provided with internal heaters (such as “blade” heaters). Without wishing to be bound by theory, because a greater proportion/surface area of the aerosol-generating material is heated by externally-heated heating assemblies, more aerosol is released than an aerosol-providing device that internally heats the aerosol-generating material, thus aerosolizing the aerosol-generating material. More condensation of aerosols occurs within the provided device.

A variety of programmed heating profiles can be used in an aerosol-providing device configured to externally heat the aerosol-generating material to provide a user with a desired amount of aerosol while keeping the amount of aerosol condensing within the aerosol-providing device relatively low. For example, the maximum operating temperature of the heating unit may affect the amount of condensate that forms. The lower the maximum operating temperatures, the less likely they are to provide undesirable condensate. Differences between the maximum operating temperatures of the heating units in a heating assembly can also affect the amount of condensate that forms. Moreover, the point at which each heating unit reaches its maximum operating temperature in a usage session can affect the amount of condensate that forms.

In use, the aerosol presentation device can heat the aerosol generating material to provide an inhalable aerosol. An aerosol delivery device may be said to be "ready for use" when at least a portion of the aerosol generating material has reached its lowest operating temperature and a user can take a puff retaining a satisfactory amount of aerosol. You can. In some embodiments, the aerosol delivery device can power one or both heating units and be ready for use in approximately 20 seconds, or 15 seconds, or 10 seconds, or 5 seconds. The aerosol delivery device may be ready for use within approximately 20 seconds, or 15 seconds, or 10 seconds, or 5 seconds after activation of the device. The aerosol presentation device may begin powering a heating unit, such as the first aerosol generator or the second aerosol generator, when the device is activated, or may begin powering the heating unit after the aerosol presentation device has been activated. The aerosol-providing device may be configured to begin supplying power to one or the heating units at a predetermined time after activation of the aerosol-providing device, such as at least 1 second, 2 seconds or 3 seconds after activation of the aerosol-providing device. The aerosol presentation device can be configured such that one of the heating units or any heating unit present in the heating assembly is de-energized until at least 2.5 seconds after activation of the aerosol presentation device. This can extend battery life by avoiding unintentional activation of the heating unit(s).

The aerosol delivery device is ready for use more quickly than corresponding aerosol delivery devices known in the art, providing an improved user experience. Typically, the point at which an aerosol-providing device is ready for use will be some time after one of the heating units has reached its maximum operating temperature because sufficient thermal energy has not been transferred from the heating unit to the aerosol-generating material to generate an aerosol. This is because it takes some time. The aerosol delivery device may be ready for use within 20 seconds, or 15 seconds, or 10 seconds, or 5 seconds after one of the heating units reaches its maximum operating temperature.

In some embodiments, the user's sensory experience resulting from the aerosol generated by the device is like smoking a combustible cigarette, such as a factory-manufactured cigarette.

The aerosol delivery device may indicate that it is ready for use via an indicator. In one embodiment, the aerosol delivery device may be configured such that an indicator indicates that the aerosol delivery device is ready for use within approximately 20 seconds, or 15 seconds, or 10 seconds, or 5 seconds after power is supplied to one of the heating units. You can. In certain embodiments, the aerosol delivery device may be configured such that an indicator indicates that the aerosol delivery device is ready for use within approximately 20 seconds, or 15 seconds, or 10 seconds, or 5 seconds after activation of the device. In another embodiment, the device is configured such that the indicator indicates that the device is ready for use within approximately 20 seconds, 15 seconds, or 10 seconds after the first aerosol generator reaches the maximum operating temperature of the first aerosol generator.

As used herein, “puff” refers to a single inhalation by a user of an aerosol produced by an aerosol delivery device.

As used herein, “session of use” refers to a single period of use of an aerosol delivery device by a user. A usage session begins at the point where power is first supplied to at least one heating unit present in the heating assembly. The device will be ready for use after a certain period of time has elapsed from the start of the use session.

The usage session ends at the point where any of the heating units of the aerosol presentation device are de-energized. The end of a use session is the point at which the aerosol-generating article is depleted (the point at which the total particulate matter yield (mg) in each puff is considered unacceptably low by the user). can match. A session may include multiple puffs. A session may have a duration of less than 7 minutes, or 6 minutes, or 5 minutes, or 4 minutes 30 seconds, or 4 minutes, or 3 minutes 30 seconds. In some embodiments, a usage session may have a duration of 2 minutes to 5 minutes, or 3 minutes to 4.5 minutes, or 3.5 minutes to 4.5 minutes, or suitably 4 minutes. A session can be initiated by the user activating a button or switch on the device, causing the at least one heating unit to begin increasing temperature when activated or some time after activation.

A usage session may be determined to begin when power or energy is first supplied to the heating unit after the aerosol generating article has been inserted into the aerosol presentation device. A usage session is where power or energy is first supplied to one or more heating units to raise their temperature to an operating temperature (Tmin) such that a user can take a first puff of aerosol generated from the aerosol generating material. It can be decided to start when it is ready. According to various embodiments, Tmin is: (i) 200 to 210° C.; (ii) 210 to 220 °C; (iii) 220 to 230° C.; (iv) 230 to 240° C.; (v) 240 to 250° C.; (vi) 250 to 260° C.; (vii) 260 to 270° C.; (viii) 270 to 280° C.; (ix) 280 to 290° C.; and (x) 290 to 300° C.

A usage session may be determined to end when power or energy is no longer supplied to one or more heating units. A usage session may be determined to end when the aerosol-generating material is substantially consumed or when the user is unable to take additional puffs of aerosol generated from the aerosol-generating material.

A usage session can be determined to relate to a period of time during which a user can take multiple puffs of aerosol generated from the aerosol-generating material without replacing or replenishing the aerosol-generating material.

In some embodiments, the aerosol presentation device may be capable of operating in at least a first (eg, base) mode of operation and a second (eg, boost) mode of operation.

The heating assembly may be capable of operating in up to two modes of operation, or may be capable of operating in more than two modes, such as three modes, four modes or five modes. Each mode of operation may be associated with a predetermined heating profile for each heating unit within the heating assembly, such as a programmed heating profile. One or more of the programmed heating profiles may be programmed by the user. Additionally or alternatively, one or more of the programmed heating profiles may be programmed by the manufacturer. In these examples, the one or more programmed heating profiles can be fixed such that an end user cannot change the one or more programmed heating profiles.

Operation modes may be selectable by the user. For example, a user can select a desired mode of operation by interacting with a user interface. Power may begin to be supplied to the first aerosol generator substantially simultaneously with the desired operating mode being selected.

Each mode may be associated with a temperature profile that is different from the temperature profiles of the other modes. Moreover, one or more modes may be associated with different points at which the device is ready for use. For example, the heating assembly is configured such that, in a first mode, the device is ready for use for a first period of time after the start of a use session and in a second mode, the device is ready for use for a second period of time after the start of the session. It can be. The first time period may be different from the second time period.

In some examples, the heating assembly can be configured to power the heating unit and be ready for use within 30 seconds, 25 seconds, 20 seconds or 15 seconds when the aerosol delivery device is operated in the first mode. The heating assembly is configured to power the heating unit and be ready for use within 25 seconds, 20 seconds, 15 seconds or 10 seconds when the aerosol delivery device is operated in the second mode - the shorter time when the aerosol delivery device is operated in the second mode. It can be. In certain embodiments, the aerosol delivery device has an indicator that the aerosol delivery device is ready for use within 20 seconds after selection of the first (e.g., base) mode and within 10 seconds after selection of the second (e.g., boost) mode. It can be configured to display.

Providing an aerosol delivery device, such as a tobacco heating product, with a heating assembly operable in multiple modes (e.g., base mode and boost mode) provides more choice to the consumer, particularly where each mode has a different maximum It is related to the heater temperature. Moreover, such an aerosol providing device can provide different aerosols with different properties because the volatile components in the aerosol generating material will volatilize at different rates and concentrations at different heater temperatures. This allows the user to select a particular mode based on desired characteristics of the inhalable aerosol, such as degree of tobacco flavor, nicotine concentration and aerosol temperature. For example, modes in which the aerosol delivery device is ready for use more quickly (e.g., secondary or “boost” mode) may provide a faster first puff, or a greater nicotine content per puff, or a more concentrated flavor per puff. can be provided. Conversely, modes in which the aerosol delivery device is ready for use at a later point in the use session (e.g., primary or base mode) may provide longer overall use sessions, lower nicotine content per puff, and more sustained delivery of flavor. You can.

In embodiments where the aerosol presentation device is more rapidly ready for use in a second (e.g., boost) mode, and/or the first and/or second aerosol generators have a higher maximum operating temperature in the second mode, The second mode may be referred to as “boost” mode. Various embodiments provide an aerosol delivery device operable in a first “normal” or “base” mode and a second “boost” mode. “Boost” mode may provide a faster first puff, or greater nicotine content per puff, or more concentrated flavor per puff.

The aerosol delivery device may include up to two heating units. In other examples, the aerosol presentation device may include more than two independently controllable heating units, such as three, four or five independently controllable heating units.

As discussed above, in some embodiments, at least one of the heating units provided in the heating assembly may include an induction heating unit. In these embodiments, the heating unit includes an inductor (eg, one or more inductor coils), and the aerosol presentation device may be arranged to pass a varying current, such as an alternating current, through the inductor. Changing current in the inductor creates a changing magnetic field. When the inductor and the heating element are appropriately positioned relatively such that the varying magnetic field generated by the inductor penetrates the heating element, one or more eddy currents are created inside the heating element. The heating element has resistance to the flow of electric currents, so when such eddy currents are created in an object, the eddy current flow against the object's electrical resistance causes the object to be heated by Joule heating. Supplying a susceptor with a changing magnetic field can conveniently be referred to as supplying energy to the susceptor.

Another aspect is an aerosol generating system comprising an aerosol providing device as described herein in combination with an aerosol generating article.

The aerosol delivery device will now be described for illustrative purposes.

1A shows an induction heating assembly 100 of an aerosol presentation device given for illustrative purposes to illustrate various aspects of a non-combustible heated aerosol presentation device. Figure 1B shows a cross-section of the induction heating assembly 100 of the device. Heating assembly 100 has a first or proximal or mouth end 102 and a second or distal end 104. In use, the user will inhale the aerosol formed from the mouth end 102 of the aerosol presentation device. Mouth end 102 may be open-ended.

Heating assembly 100 includes a first induction heating unit 110 and a second induction heating unit 120. The first induction heating unit 110 includes a first inductor coil 112 and a first heating element 114. The second induction heating unit 120 includes a second inductor coil 122 and a second heating element 124.

FIGS. 1A and 1B depict an aerosol-generating article 130 contained within a single susceptor 140 (see FIG. 1B). A single susceptor 140 forms both the first induction heating element 114 and the second induction heating element 124. Susceptor 140 may be formed of any material suitable for heating by induction. For example, the susceptor 140 may include metal. In some embodiments, susceptor 140 may include non-ferrous metals such as copper, nickel, titanium, aluminum, tin, or zinc, and/or ferrous materials such as iron, nickel, or cobalt. Additionally or alternatively, susceptor 140 may include a semiconductor such as silicon carbide, carbon, or graphite.

Each induction heating element present within the aerosol presentation device may have any suitable shape. In the embodiment shown in Figure 1B, induction heating elements 114, 124 surround the aerosol-generating article and define a receptacle for externally heating the aerosol-generating article. In another arrangement (not shown), the one or more induction heating elements may be substantially elongated and arranged to penetrate the aerosol-generating article and internally heat the aerosol-generating article.

As shown in FIG. 1B , the first induction heating element 114 and the second induction heating element 124 may be provided together as a monolithic susceptor element 140 . That is, in some embodiments, there is no physical distinction between the first heating element 114 and the second heating element 124. Rather, the different characteristics between the first and second aerosol generators 110, 120 are defined by separate inductor coils 112, 122 surrounding each induction heating element 114, 124, and thus These can be controlled independently of each other. In other embodiments (not shown), physically distinct induction heating elements may be used.

The first and second inductor coils 112 and 122 may be made of electrically conductive material. For example, the first and second inductor coils 112, 122 are manufactured from LITZ (RTM) wire/cable wound in a helically wound manner to provide helical inductor coils 112, 122. It can be. Ritz (RTM) wire includes a plurality of individual wires that are individually insulated and twisted together to form a single wire. RTM wires are designed to reduce skin effect losses in the conductor. In the exemplary induction heating assembly 100, the first and second inductor coils 124, 126 are made from copper Ritz (RTM) wire having a circular cross-section. In other examples, RTM wire may have cross-sections of other shapes, such as rectangular.

The first inductor coil 112 is configured to generate a varying first magnetic field for heating the first induction heating element 114, and the second inductor coil 122 is configured to heat the second section of the susceptor 124. It is configured to generate a changing second magnetic field for The first inductor coil 112 and the first induction heating element 114 together form a first induction heating unit 110 . Similarly, the second inductor coil 122 and the second induction heating element 124 together form a second induction heating unit 120.

In this example, first inductor coil 112 is adjacent second inductor coil 122 in a direction along the longitudinal axis of device heating assembly 100 (i.e., first and second inductor coils 112, 122). do not overlap). Susceptor arrangement 140 may include a single susceptor. Ends 150 of the first and second inductor coils 112 and 122 may be connected to a controller such as a PCB (not shown). In embodiments, the controller may include a PID controller (proportional integral derivative controller).

The changing magnetic field generates eddy currents in the first induction heating element 114, thereby supplying alternating current to the coil 112 for a short period of time, for example, 20 seconds, 15 seconds, 12 seconds, 10 seconds, 5 seconds. Alternatively, rapidly heat the first induction heating element 114 to the maximum operating temperature within 2 seconds. Arranging the first induction heating unit 110, which is configured to rapidly reach the maximum operating temperature, closer to the mouth end 102 of the heating assembly 100 than the second induction heating unit 120 may result in an acceptable aerosol This may mean that it is provided to the user as soon as possible after the start of the usage session.

It will be appreciated that the first and second inductor coils 112 and 122 may, in some examples, have at least one characteristic that is different from each other. For example, the first inductor coil 112 may have at least one characteristic different from the second inductor coil 122. More specifically, in one example, the first inductor coil 112 may have a different inductance value than the second inductor coil 122. 1A and 1B, the first and second inductor coils 112, 122 are wound on different sections of the susceptor 140, with the first inductor coil 112 being wound over a smaller section of the susceptor 140 than the second inductor coil 122. It is made up of lengths. Accordingly, the first inductor coil 112 may include a different number of turns than the second inductor coil 122 (assuming that the spacing between individual turns is substantially the same). In another example, first inductor coil 112 may be made of a different material than second inductor coil 122. In some examples, the first and second inductor coils 112 and 122 may be substantially identical.

In this example, first inductor coil 112 and second inductor coil 122 are wound in the same direction. However, in another embodiment, inductor coils 112, 122 may be wound in opposite directions. This can be useful when inductor coils are activated at different times. For example, initially, the first inductor coil 112 may be operating to heat the first induction heating element 114 and later, the second inductor coil 122 may be operating to heat the second induction heating element 124. ) can be operated to heat. Winding the coil in opposite directions helps reduce the current drawn in the inactive coil when used with certain types of control circuitry. In one example, the first inductor coil 112 is a right-hand helix and the second inductor coil 122 is a left-hand helix. In another example, the first inductor coil 112 may be a left-handed helix, and the second inductor coil 122 may be a right-handed helix.

Coils 112, 122 may have any suitable geometric shape. Without being bound by theory, smaller configurations of the induction heating element (e.g., smaller pitch helix, fewer helical turns; shorter overall helix length) will increase the rate at which the induction heating element can reach its maximum operating temperature. You can. In some embodiments, the first coil 112 may have a length of approximately less than 20 mm, less than 18 mm, less than 16 mm, or approximately 14 mm in the longitudinal direction of the heating assembly 100. The first coil 112 may have a shorter length than the second coil 124 in the longitudinal direction of the heating assembly 100. Such an arrangement can provide asymmetric heating of the aerosol-generating article along the length of the aerosol-generating article.

The single susceptor 140 in this example is hollow and thus defines a receptacle in which aerosol generating material is received. For example, article 130 may be inserted into susceptor 140. In this example, susceptor 140 is tubular with a circular cross-section. Induction heating elements 114 , 124 surround the aerosol-generating article 130 and are arranged to heat the aerosol-generating article 130 externally. The aerosol presentation device is configured such that when the aerosol-generating article 130 is received within the susceptor 140, the exterior surface of the article 130 contacts the interior surface of the susceptor 140. This ensures that heating takes place most efficiently. Article 130 in this example includes an aerosol generating material. Aerosol generating material is positioned within susceptor 140. Article 130 may also include other components, such as filters, wrapping materials, and/or cooling structures. Heating assembly 100 is not limited to two heating units. In some examples, heating assembly 100 may include 3, 4, 5, 6 or more than 6 heating units. Each of these heating units may be controllable independently from other heating units present in heating assembly 100.

2A and 2B, a partial cutaway cross-sectional and perspective view of an example of an aerosol-generating article 200 is shown for illustrative purposes only. Aerosol-generating article 200 shown in FIGS. 2A and 2B corresponds to aerosol-generating article 130 shown in FIG. 1 .

Aerosol-generating article 200 may be of any shape suitable for use with an aerosol-providing device. Aerosol generating article 130 may be provided in the form of, or part of, a cartridge, cassette, or rod that can be inserted into a device. 1A, 1B and 2, the aerosol-generating article 130 is in the form of a substantially cylindrical rod comprising a body of smokable material 202 and a rod-shaped filter assembly 204.

Filter assembly 204 has three segments; It includes a cooling segment (206), a filter segment (208) and a mouth end segment (210). The article 200 has a first end 212, also known as the mouth end or proximal end, and a second end 214, also known as the distal end. The body of aerosol generating material 202 is positioned toward the distal end 214 of the article 200.

In one example, the cooling segment 206 is positioned adjacent the body of the aerosol-generating material 202 between the body of the aerosol-generating material 202 and the filter segment 208 such that the cooling segment 206 It is in an abutting relationship with the material 202 and the filter segment 208. In other examples, there may be a gap between the body of aerosol-generating material 202 and the cooling segment 206 and between the body of aerosol-generating material 202 and the filter segment 208. Filter segment 208 is positioned between cooling segment 206 and mouth end segment 210. Mouth end segment 210 is positioned toward proximal end 212 of article 200 adjacent filter segment 208. In one example, filter segment 208 is in abutting relationship with mouse end segment 210. In one embodiment, the overall length of filter assembly 204 is between 37 mm and 45 mm, and optionally, the overall length of filter assembly 204 is 41 mm.

In use, portions 202a, 202b of the body of aerosol generating material 202 are connected to first induction heating element 114 and second induction heating element 124, respectively, of portion 100 shown in FIG. 1B. We can respond.

The body of smokable material may have a plurality of portions 202a, 202b corresponding to a plurality of induction heating elements present within the aerosol presentation device. For example, the aerosol-generating article 200 can have a first portion 202a corresponding to the first induction heating element 114 and a second portion 202b corresponding to the second induction heating element 124. . These portions 202a, 202b may exhibit different temperature profiles during a use session. The temperature profiles of the portions 202a, 202b may be derived from the temperature profiles of the first induction heating element 114 and the second induction heating element 124, respectively.

If there are multiple portions 202a, 202b of the body of aerosol-generating material 202, any number of substrate portions 202a, 202b may have substantially the same composition. In certain examples, all portions of the substrate 202a, 202b have substantially the same composition. The body of aerosol-generating material 202 may be an integral continuous body, and there may be no physical separation between the first and second portions 202a, 202b. Moreover, the first and second portions 202a and 202b may have substantially the same composition.

According to various embodiments, the body of aerosol-generating material 202 includes tobacco. The body of smokable material 202 may consist of tobacco, may consist substantially entirely of tobacco, may include tobacco and an aerosol-generating material other than tobacco, or may include an aerosol-generating material other than tobacco. There may be, or there may be no cigarettes. Aerosol-generating materials may include aerosol-generating agents such as glycerol. In certain embodiments, the aerosol-generating material may include one or more tobacco components, filler components, binders, and aerosol-generating agents.

An “aerosol generating agent” is an agent that promotes the creation of an aerosol. Aerosol generating agents may facilitate the creation of aerosols by promoting initial vaporization and/or condensation of the gas into inhalable solid and/or liquid aerosols. In some embodiments, an aerosol generating agent can improve the delivery of flavor from an aerosol generating article.

In certain embodiments, the aerosol generating material comprises a tobacco component in an amount of 60 to 90% by weight of the tobacco composition, a filler component in an amount of 0 to 20% by weight of the tobacco composition, and an amount of 10 to 20% by weight of the tobacco composition. It includes an aerosol generating agent. The tobacco component may include paper reconstituted tobacco in an amount of 70 to 100% by weight of the tobacco component. In one example, the body of aerosol-generating material 202 is between 34 mm and 50 mm in length, optionally the body of aerosol-generating material 202 is between 38 mm and 46 mm in length, and even more preferably, the body of aerosol-generating material 202 is between 38 mm and 46 mm in length. The body of 202 is 42 mm long.

In one example, the total length of the article 200 is between 71 mm and 95 mm, optionally the total length of the article 200 is between 79 mm and 87 mm, and optionally the overall length of the article 200 is 83 mm. The axial end of the body of aerosol generating material 202 is visible at the distal end 214 of article 200. However, in other embodiments, the distal end 214 of the article 200 may include an end member (not shown) that covers the axial end of the body of the aerosol-generating material 202.

The body of aerosol generating material 202 is coupled to the filter assembly 204 by an annular tipping paper (not shown), which tipping paper substantially surrounds the filter assembly 204 ( It is located around the circumference of the aerosol generating material 204 and extends partially along the length of the body of the aerosol generating material 202. In one example, the tipping paper is made from 58GSM standard tipping base paper. In one example, the tipping paper has a length of 42 mm to 50 mm, optionally the tipping paper has a length of 46 mm.

In one example, cooling segment 206 is an annular tube positioned around and defining an air gap within the cooling segment. The voids provide a chamber through which heated and volatilized components originating from the body of aerosol generating material 202 flow. The cooling segment 206 is hollow to provide a chamber for aerosol accumulation, but is capable of absorbing axial compressive forces and bending moments that may occur during manufacturing and while the article 200 is being inserted into the device 100 in use. It has sufficient rigidity to withstand. In one example, the wall thickness of cooling segment 206 is approximately 0.29 mm.

Cooling segment 206 provides physical displacement between aerosol-generating material 202 and filter segment 208. The physical displacement provided by cooling segment 206 will provide a thermal gradient over the length of cooling segment 206. In one example, the cooling segment 206 has a temperature of at least 40° C. between the heated volatilized component entering the first end of the cooling segment 206 and the heated volatilized component exiting the second end of the cooling segment 206. It is configured to provide a temperature difference of In one example, the cooling segment 206 has a temperature of at least 60° C. between the heated volatilized component entering the first end of the cooling segment 206 and the heated volatilized component exiting the second end of the cooling segment 206. It is configured to provide a temperature difference of This temperature difference across the length of the cooling element 206 causes the temperature sensitive filter segment 208 to move from the high temperature of the aerosol generating material 202 when heated by the heating assembly 100 of the device aerosol providing device. ) protects. If no physical displacement is provided between the filter segment 208 and the body of the aerosol generating material 202 and the heating elements 114, 124 of the heating assembly 100, the temperature sensitive filter segment 208 may be damaged during use. and thus will not be able to effectively perform the required functions of the filter segment.

In one example, the length of cooling segment 206 is at least 15 mm. In one example, the length of the cooling segment 206 is 20 mm to 30 mm, more particularly 23 mm to 27 mm, more particularly 25 mm to 27 mm, more particularly 25 mm.

The cooling segment 206 may be made of paper, thus being constructed of a material that does not produce compounds of interest, for example toxic compounds, when in use adjacent to the heater assembly 100 of the aerosol presentation device. In one example, the cooling segment 206 may be manufactured from a spirally wound paper tube that provides a hollow internal chamber but maintains mechanical rigidity. Spiral wound paper tubes can meet the stringent dimensional accuracy requirements of high-speed manufacturing processes with respect to tube length, outer diameter, roundness and straightness.

In another example, cooling segment 206 is a recess created from stiff plug wrap or tipping paper. The rigid plug wrap or tipping paper is manufactured with sufficient rigidity to withstand axial compressive forces and bending moments that may occur during manufacturing and while the article 200 is being inserted into the device 100 in use.

For each of the examples of cooling segment 206, the dimensional accuracy of the cooling segment is sufficient to meet the dimensional accuracy requirements of a high-speed manufacturing process.

Filter segment 208 may be formed of any filter material sufficient to remove one or more volatilized compounds from heated volatilized components from the smokable material. In one example, filter segment 208 is made from a mono-acetate material, such as cellulose acetate. Filter segment 208 provides cooling and irritation-reduction from heated volatilized components without depleting the amount of heated volatilized components to levels unsatisfactory to the user.

The density of the cellulose acetate tow material of the filter segment 208 controls the pressure drop across the filter segment 208, which in turn controls the draw resistance of the article 200. Accordingly, material selection of filter segment 208 is important in controlling the resistance to attraction of article 200. Filter segment 208 also performs a filtration function for article 200.

In one example, the filter segment 208 is made of 8Y15 grade filter tow material, which provides filtration for the heated volatilized material while also reducing the size of condensed aerosol droplets resulting from the heated volatilized material. This reduces the irritation and throat impact of the heated volatilized material to a satisfactory level.

The presence of filter segment 208 provides an insulating effect by providing additional cooling to the heated volatilized components exiting cooling segment 206. This additional cooling effect reduces the contact temperature of the user's lips on the surface of the filter segment 208. One or more flavors may be added in the form of injecting flavored liquids directly into the filter segment 208, or as one or more flavored breakable capsules or other flavors within the cellulose acetate tow of the filter segment 208. Flavor carriers may be added to the filter segment 208 by embedding or arranging them.

In one example, filter segment 208 is between 6 mm and 10 mm in length, optionally about 8 mm. Mouth end segment 210 is an annular tube positioned circumferentially and defining a void within mouth end segment 210 . The voids provide a chamber for heated volatilized components flowing from the filter segment 208.
