Description

TECHNICAL FIELD

[0001] The present invention relates to an aerosol-generating device comprising a main body having an aerosol-generating article receiving cavity and an actuator, and preferably at least one of a heater and a battery compartment. BACKGROUND

[0002] In the use of portable devices for the purpose of inhalation of recreational and nicotine-containing aerosols, applicable regulations and laws are presenting a trend towards greater focus on child protection.

[0003] There are currently no devices on the market with an effective technical child safety solution.

[0004] It is also known that devices for aerosolization of nicotine-containing substances, i.e. via heat-not-burn (HNB) or heat tobacco product (HTP) technology, can lack a flavour and aroma atmosphere compared to conventional products, e-vaping systems and inhalable pharmaceutical products, which can be combined with other consumable products, such as flavourings etc. It is therefore desirable that devices can include additional flavour release, which can enhance the overall consumer experience within the HTP / HNB product aerosolization range.

[0005] Problem to be solved:

[0006] Current aerosol-generating devices on the market can be used by users who are not authorized by their owners, i.e. when the device is unattended, which can include underage users, including children, attempting to use. Such as in the case where a consumer is at home and can leave an aerosol-generating device and corresponding aerosol-generating articles unattended in different places around the home, and thus underage users, including their children, can attempt to use the aerosol-generating device in many ways.

[0007] Within the scope of child safety features in nicotine delivery devices and products, there is an increasing demand for regulatory frameworks, and thus technical solutions to avoid the use of aerosol-generating devices and products by underage users are considered strategically significant to the business.

[0008] At the same time, it is desirable to provide users with the possibility to modify or otherwise change the flavour of inhalable aerosols originating from consumables, such as tobacco-based consumables, by using additional flavour release consumables.

[0009] In summary, the problem to be solved is to provide an aerosol-generating device comprising a child safety solution. It is preferable to also be able to release flavours to enhance the consumer experience, and possibly release a pleasant aroma to suppress potential residual odours within the device. SUMMARY

[0010] To address the above problems, the present invention provides an aerosol generating apparatus according to claim 1. Preferred embodiments are claimed in the dependent claims.

[0011] According to one aspect of the invention, an aerosol generating apparatus is provided, comprising a body having an aerosol generating article receiving cavity and an actuator. The aerosol generating apparatus further includes a key unit detachably attached to the body, wherein detachment of the key unit from the body switches the apparatus from an operational state to a non-operating state. In the operational state, actuation of the actuator allows a heater to operate to heat the aerosol generating article received in the cavity to generate an aerosol. In the non-operating state, the apparatus is unable to generate and / or release aerosols, and wherein attachment of the key unit to the body switches the apparatus from the non-operating state to the operational state. The body or aerosol generating article to be used in combination with the apparatus may further include a heater and a battery (compartment). The body may also include one of a heater and a battery, while the aerosol generating article includes the other of a heater and a battery.

[0012] Therefore, the aerosol generator is either operational or inoperable depending on whether the key unit is attached to the main body. The key unit thus functions as a child safety lock. For example, the key unit therefore works like a key to prevent unauthorized and unattended use of the aerosol generator (especially by children or infants). This safety feature meets current market and regulatory requirements for child safety technology solutions for portable aerosol generators.

[0013] According to claim 1, the attachment / removal of the key unit from the body only switches the device to an operational / inoperable state, respectively. This may cover any indirect causal relationship between attachment / removal and switching (e.g., by means of sensors and controllers).

[0014] More specifically, the key unit is an additional component attached to the main body. In the absence of any other functional, technical, or electrical requirements, the key unit can be an inexpensive, lightweight, simple item that can be purchased separately from the main body and has customizable aesthetics. The heater, battery compartment, and actuator are not part of the key unit themselves, as these items are designed and constructed to meet specific functional, technical, and / or electrical requirements, necessitating complex mechanical and electrical interfaces and increasing their cost, size, and weight.

[0015] Mechanical key (claim 2)

[0016] In a preferred embodiment, the key unit may be a mechanical key that mechanically switches the device from an operational state to a non-operational state by detaching it from the body, and mechanically switches the device from a non-operational state to an operational state by attaching it to the body, wherein the key unit preferably does not contain electronic components or other active parts. This allows for a very simple, inexpensive, and lightweight design of the key unit, as well as easy attachment and detachment from the body. According to claim 2, the attachment / detachment of the key unit from the body switches the device to an operational / non-operational state, meaning that the attachment / detachment of the key unit from the body is a direct / active causal relationship for the device switching to an operational / non-operational state.

[0017] The key unit (disconnected) connects to the battery and heater (claim 3).

[0018] In another preferred embodiment, detachment of the key unit from the body can disconnect the heater from the battery (particularly the battery included in or received in the battery compartment), and attachment of the key unit to the body can connect the heater to the battery.

[0019] Therefore, whether there is an electrical connection between the battery and the heater depends on whether the key unit is attached to the main body. Without power from the battery, the heater cannot heat the aerosol generating article received in the aerosol generating article receiving chamber, effectively preventing aerosol generation in the non-operating state. On the other hand, since the attachment of the key unit to the main body establishes an electrical connection between the battery and the heater, aerosol generation is only possible in the operating state.

[0020] The interaction between the key unit and the electrical connection (between the battery and the heater) provides an additional safety feature to prevent unauthorized use of the aerosol generating device, as the removal of the key unit from the main body electrically disables the operation of the aerosol generating device.

[0021] The key unit affects the airflow in the cavity (claim 4).

[0022] In another preferred embodiment, detachment of the key unit from the body can degrade or disable airflow within the aerosol-generating article receiving cavity, rendering the device unable to generate and / or release aerosols, while attachment of the key unit to the body can improve or enable airflow within the aerosol-generating article receiving cavity, enabling the device to generate and / or release aerosols. The aerosol generated by the device can be delivered to a user or consumer via a mouthpiece.

[0023] More specifically, detaching the key unit from the main body allows opening the aerosol generating article receiving cavity, particularly its upstream end, to fluidly connect it to open air, preventing the user from aspirating the aerosol generated by the aerosol generating article. Attaching the key unit to the main body closes the aerosol generating article receiving cavity, particularly its upstream end, to fluidly disconnect it from open air. The upstream end of the aerosol generating article receiving cavity is the position where the insertion end of the aerosol generating article received in the cavity is positioned during aerosol generation. This end of the aerosol generating article receiving cavity is referred to as the "upstream end" because it is located upstream of the aerosol generating article during user aerosol consumption. The airflow of the aerosol generating article received in the cavity can be triggered by the user's aspiration. The airflow begins at the insertion end of the aerosol generating article and then passes through the entire aerosol generating article to generate an aerosol, wherein the aerosol generated by distributing particles (e.g., particles of heated tobacco) into the airflow passing through the article exits the article through the end located outside the receiving cavity of the aerosol generating article.

[0024] The key unit, particularly its key portion, can be a core functional part for operating the device, particularly a core functional part for the device's air management, wherein the key unit can define at least a portion of the airflow channel and air intake structure for supplying air to the aerosol generation chamber during the device's operating state.

[0025] An inlet chamber (or reservoir) may be located upstream of the aerosol generation article receiving chamber. This inlet chamber may be filled with ambient air when the user is not drawing aerosol from the aerosol generation article received in the aerosol generation article receiving chamber. An upstream air passage may exist from the external environment to the inlet chamber and the keyhole portion of the receiving key element. The air capacity and air resistance of the inlet chamber can be fluidly adapted to the user's typical drawing. When the user begins drawing aerosol from the aerosol generation article, air from the inlet chamber may flow into the aerosol generation article. This creates a negative pressure within the inlet chamber or reservoir, which draws (draws in) ambient air from the outside of the device or the external environment once the user stops drawing aerosol from the aerosol generation article. The limited air capacity of the inlet chamber and the airflow arrangement in the aerosol generation article receiving chamber provide a specific draw resistance (RTD). The draw resistance (RTD) can be controlled within a defined range by the elements forming the aerosolization chamber during operation. In the operating state, the RTD can be in the range of 10 to 150 mmWG (millimeters of water column), more preferably 20 to 140 mmWG, and even more preferably 30 to 120 mmWG. In the non-operating state, an additional fluid connection from the aerosol generation article receiving cavity to the external environment is created through an unoccupied keyhole, allowing the RTD to decrease to a value below 30 mmWG, preferably below 20 mmWG, and more preferably below 10 mmWG.

[0026] The key unit modifies the interaction of airflow within the aerosol generation article receiving cavity, providing another safety feature to prevent unauthorized use of the aerosol generation device.

[0027] Detection unit (claim 5)

[0028] In another preferred embodiment, the device may further include a detection unit configured to detect attachment of the key unit to the body / removal from the body, wherein the detection unit may be configured to switch the device to an operating state when attachment of the key unit is detected, and to switch the device to a non-operating state when removal of the key unit is detected.

[0029] The detection unit may include a presence sensor or a distance sensor, wherein the presence sensor or distance sensor may be a capacitive sensor, an optical sensor, or an inductive sensor, etc.

[0030] The detection unit may include a pressure sensor that is pressed by the key unit when the key unit is attached and not pressed when the key unit is detached. The pressure sensor may include a spring pin or a button.

[0031] The interaction between the key unit and the detection unit provides an additional security feature to prevent unauthorized use of the aerosol generating device.

[0032] Keyhole and key portion (claim 6)

[0033] In another preferred embodiment, the main body may include a keyhole, and the key unit may include a corresponding key portion that engages with the keyhole to achieve an operational state.

[0034] In the non-operating state, the keyhole can be in fluid communication with the aerosol generation article receiving cavity and the external environment, allowing air from the external environment to enter or escape from the aerosol generation article receiving cavity through the keyhole.

[0035] In operation, the keyhole can be closed relative to the external environment by the key unit, especially by the key unit's airtight seal.

[0036] The key portion may be at least partially coated (preferably in its top and bottom surfaces), particularly by a layer of elastomeric material (such as an FDA-approved silicone-based polymer compound) to provide a seal, which ensures an airtight seal of the keyhole in the operational state.

[0037] The keyhole can be set in the convex surface of the main body.

[0038] The keyhole can be set on the edge of the main body.

[0039] The keyhole may be located in the center of the length and / or width and / or height of the body, preferably in the middle third of the length and / or width and / or height of the body.

[0040] The inner cross-sectional shape of the keyhole can be adapted to or complement the outer cross-sectional shape of the key portion in the insertion direction of the key portion.

[0041] The keyhole can have a slit-shaped opening.

[0042] The key portion can protrude from the concave side of the key unit.

[0043] The key portion can protrude from the decorative elements of the key unit, especially in a direction perpendicular to the decorative elements.

[0044] In operation, the key section can separate the aerosol generation article receiving chamber from the air inlet chamber provided in the main body, and can force air to flow from the air inlet chamber through the air passage provided in the key section before entering the aerosol generation article receiving chamber.

[0045] An air passage may lead to the article receiving chamber containing the substance in the key section, such that air passing through the air passage (e.g., triggered by a user's suction) flows through the article containing the substance received in the article receiving chamber containing the substance before entering the article receiving chamber containing the aerosol generation disposed downstream.

[0046] Air passages can be formed by transverse holes or openings with a diameter of approximately 0.1 to 2 mm.

[0047] In operation, the key portion can guide the air flowing into the aerosol generating article receiving chamber through the aerosol generating article received therein.

[0048] In operation, the key portion can limit the bottom of the aerosol-generating article receiving cavity.

[0049] The complementary fit between the keyhole and the key portion provides an additional security feature that prevents unauthorized use of the aerosol generating device by preventing the insertion of a key-like object into the keyhole to attempt to simulate the presence of the key portion and manipulate the device.

[0050] Decorative element (claim 7)

[0051] In yet another preferred embodiment, the key unit may include decorative elements that remain visible in the operational state.

[0052] The portion of the key unit that includes decorative elements may cover the exposed surface of the body, preferably a convex surface.

[0053] Decorative elements may include decorative surfaces, such as decorative patterns, one or more symbols, one or more logos, or combinations thereof.

[0054] Decorative elements can be walls, parts, shells, or covers.

[0055] Decorative elements may include at least one of the following: texture and color, pattern, embossing, perforation, and structure (e.g., snakeskin fabric or gray carbon fiber).

[0056] Decorative elements may be adhesively attached, bonded, welded, or soldered to the key unit or integrally formed with the key unit (e.g., by 3D printing).

[0057] The portion of the key unit that includes decorative elements may extend substantially orthogonally to the key portion of the key unit.

[0058] In the operational state, the portion of the key unit including decorative elements may occupy or cover at least one of the following dimensions on at least one side of the main body:

[0059] The height of the main body is at least 50%, 70%, or 90%, preferably 100%.

[0060] The length of the main body is at least 50%, 70%, or 90%, preferably 100%.

[0061] The width of the main body is at least 50%, 70%, or 90%, preferably 100%.

[0062] A key unit configured to hold a material-containing article (claim 8)

[0063] In yet another preferred embodiment, the key unit, particularly its key portion, may be configured to hold the substance-containing article to release the substance of the substance-containing article in an operational state to generate a modified aerosol.

[0064] The key unit may include a material article receiving cavity, which is configured to preferably receive the material article upstream of the aerosol generation article receiving cavity.

[0065] The key unit can be configured to support a substance-containing article in the operating state, such that the substance-containing article releases its substance into the aerosol-generating article receiving chamber, particularly into the upstream end of the aerosol-generating article receiving chamber, or into the aerosol-generating article received in the aerosol-generating article receiving chamber, or into the aerosol generated by the aerosol-generating device, or into the gas flow used to generate the aerosol.

[0066] Products containing substances can be flavored or aromatic. Releasing pleasant flavors or aromas can enhance the consumer experience.

[0067] Products containing substances may contain pharmaceutical ingredients, plant-derived materials, etc.

[0068] Shape-fit friction fit (claim 9)

[0069] In yet another preferred embodiment, the key unit can be detachably attached to the body by form-fitting and / or by magnetic force.

[0070] The key unit can be detachably attached to the main body via a snap-fit ​​mechanism.

[0071] The key unit can surround the two opposite edges of the main body in the operating state or be arranged flush with the two opposite edges of the main body.

[0072] The key unit can be configured to be attached to and removed from the main body without tools.

[0073] The key unit can be elastically deformable to attach to and detach from the body.

[0074] The key unit can be configured to expand for detachment from the main body and to retract for attachment to the main body.

[0075] The key unit can be configured as a bracket.

[0076] The key unit can be attached to the main body by clamping.

[0077] The key unit can be made of metal and / or plastic.

[0078] The key unit may include an elastomer.

[0079] The key unit can cover at least one side surface of the body across its entire width and / or length and / or height.

[0080] One side of the key unit facing the main body can be in full contact with the main body in the operating state, without any gap between them.

[0081] The key unit can fit snugly into the main body while in operation.

[0082] The aforementioned features provide considerable freedom in attaching / removing the key unit from the main body.

[0083] A key unit configured to position an aerosol-generating article (claim 10)

[0084] In yet another preferred embodiment, the key unit may be configured to receive the aerosol-generated article in the aerosol-generated article receiving cavity, particularly in the operational state, relative to the heater.

[0085] The key portion can be configured to at least partially support the aerosol generating article, particularly the front end of the aerosol generating article, received in the aerosol generating article receiving cavity in the operating state.

[0086] The key unit can be configured to position the aerosol generating article received in the aerosol generating article receiving cavity during operation, allowing the heater to heat the aerosol generating material contained in the aerosol generating article to generate aerosol. Removal of the key unit from the main body may result in the same aerosol generating article being improperly positioned in the aerosol generating cavity, preventing the aerosol generating material contained in the aerosol generating article from being heated by the heater, resulting in no aerosol generation or only insufficient aerosol generation even when heated.

[0087] Therefore, the aerosol-generating article can only be correctly positioned in the aerosol-generating article receiving cavity when the key unit is attached to the main body. The absence of the key unit will cause misalignment of the aerosol-generating article in the aerosol-generating article receiving cavity, particularly relative to the heater or relative to the airflow passing through the aerosol-generating article receiving cavity. Consequently, due to the misalignment of the aerosol-generating article, the aerosol generating device will be inoperable without the key unit.

[0088] Second key unit (claim 11)

[0089] In yet another preferred embodiment, the device may further include a second key unit detachably attached to the body in place of the first key unit, wherein the first and second key units may differ at least in their decorative elements. The decorative elements may be used for, for example, personalization purposes.

[0090] The device may include sensors configured to identify each of a first key unit and a second key unit, wherein the sensors may be configured to switch the device to a first operating mode upon identification of the first key unit, and wherein the sensors may be configured to switch the device to a second operating mode different from the first operating mode upon identification of the second key unit. The sensors may generate a first signal upon identification of the first key unit and a second signal upon identification of the second key unit. The device may also include a controller that may generate a first command to switch the device to the first operating mode upon receiving the first signal, and may generate a second command to switch the device to the second operating mode upon receiving the second signal. This may be embodied, for example, by RFID tags, optical tags, patterns or codes, different mechanical structures of the first and second key units, etc.

[0091] A system comprising an aerosol generating apparatus and an article of manufacture (claim 12)

[0092] According to another aspect of the invention, a system is provided comprising an aerosol generating apparatus according to any of the foregoing aspects and embodiments, and at least one aerosol generating article configured to be received in an aerosol generating article receiving cavity so as to generate an aerosol when the aerosol generating article is heated by a heater in an operational state.

[0093] In the operating state, the static pressure difference (representing suction resistance (RTD)) between the two ends of the aerosol generating article receiving chamber in the aerosol generating article receiving cavity, measured according to ISO standard 6565:2002 under conditions where any ventilation is blocked, can be in the range of 10 to 150 mmWG, more preferably 20 to 140 mmWG, and even more preferably 30 to 120 mmWG. In the non-operating state, an additional fluid connection from the aerosol generating article receiving cavity to the external environment is created through an unoccupied keyhole, such that the RTD can be reduced to a value below 30 mmWG, preferably below 20 mmWG, and more preferably below 10 mmWG.

[0094] The key portion can be configured to retain, in particular, its insertion end, the aerosol-generating article received in the aerosol-generating article receiving cavity during operation.

[0095] The key unit can be configured to position and receive the aerosol generating article in the aerosol generating chamber during operation, so that the heater can heat the aerosol generating substance contained in the aerosol generating article to generate aerosol.

[0096] Disassembling the key unit from the main body may result in the same aerosol generating article being improperly positioned in the aerosol generating chamber, preventing the aerosol generating substances contained in the aerosol generating article from being heated by the heater, so that even if heated, no aerosol is generated or only insufficient aerosol is generated.

[0097] Aerosol-generating products may be, but are not limited to, nicotine-containing product (NCP) cartridges or tobacco sticks.

[0098] It also includes systems containing articles of substance (claim 13).

[0099] According to another aspect of the invention, a system according to the preceding aspect is provided, wherein the system further includes at least one substance-containing article configured to be held by a key unit to interact in an operational state with an aerosol-generating article received in an aerosol-generating article receiving cavity in order to generate a modified aerosol.

[0100] Articles containing substances may be made of porous media or include porous matrices.

[0101] Articles containing substances may include sensory media that release flavor compounds and aromas.

[0102] Articles containing substances may be disc-shaped or may be impregnated with flavoring substances (in liquid and / or gel form).

[0103] Articles containing substances may be one of the following types of porous materials:

[0104] a) Ceramic compounds, for example, because they are available on the market for use in devices for releasing fragrance into the environment and devices for aromatherapy.

[0105] b) Material compounds selected from silicon carbide, silicon-based compounds, cordierite, silicon dioxide, and zirconium-based ceramic compounds.

[0106] c) Compounds suitable for sintering in terms of particle size to obtain a desired porosity range, such as porous silica ceramics typically produced by the silica spinning solution industry, wherein silica particles are introduced by electrospinning and then subjected to sintering to obtain the final desired geometry and size, as well as the desired porosity, wherein the sintering process can be carried out at a temperature of about 1000°C to 1200°C.

[0107] Products containing substances can be sintered porous products.

[0108] The porosity of the article containing the substance can be about 30% to 80%, preferably about 40% to 70%, and most preferably about 50% to 60%.

[0109] The porosity of sintered materials can be adjusted by changing the content and size of the introduced silica particles, which makes it possible to control the desired porosity for the final product.

[0110] Given the pore volume (Vp) and total volume (Vt) of a material with a defined volume, the porosity mentioned is given as a decimal value using standard methods and formulas, where the porosity (Pt) is given by the ratio Vp / Vt, where the porosity is expressed as a percentage, that is, the decimal is simply multiplied by 100%, for example, Pt = 0.51, therefore 0.51 x 100% = 51%.

[0111] Articles containing such materials can be designed and manufactured using natural materials such as porous basalt-based materials, granulated commercially available natural open-pore porous stone, and combinations of these materials with silicon-based compounds, as both are commonly used in the production of sintered porous products.

[0112] Products containing this substance may meet FDA requirements for food and beverage (F&B) and medical devices.

[0113] The group may also include at least two different articles containing substances, which differ in shape and / or substance. Articles containing substances may contain at least one of the following: flavoring / seasoning substances, plant-derived materials, pharmaceutical products, etc.

[0114] Method for operating an aerosol generating apparatus (claim 14)

[0115] According to another aspect of the invention, a method is provided for operating an aerosol generating apparatus or system according to any of the foregoing aspects and embodiments, the method comprising the following steps, preferably but not necessarily in the order ABCD or BACD:

[0116] Step A: Attach the key unit to the main body so that the device switches from the inoperable state to the operating state.

[0117] Step B: Receive the aerosol-generated article in the aerosol-generated article receiving cavity.

[0118] Step C: Actuate the actuator to operate the heater to heat the aerosol generating article received in the aerosol generating article receiving chamber to generate an aerosol.

[0119] Step D: Remove the key unit from the main body so that the device can be switched from the operating state to the non-operating state.

[0120] Although the preferred order of the method steps is ABCD, the method steps can also be performed in a different order, such as BACD.

[0121] Method for generating modified aerosols (claim 15)

[0122] Step C may further include: using the key portion to hold the article containing the substance to interact with the aerosol-generating article to generate a modified aerosol. Prior to attachment of the key unit to the body, the article containing the substance may be inserted into the article containing the substance receiving cavity of the key unit, particularly the key portion of the key unit.

[0123] Other preferred embodiments arise from a combination of features disclosed in the description, claims, and drawings.

[0124] Terms and Definitions

[0125] The term "aerosol generating device" applies to all devices configured to generate aerosols. Aerosol generating devices can be portable, handheld devices. They can operate off-grid and can be battery-powered.

[0126] The term "aerosol-generating article" applies to all articles that can be used to generate aerosols, such as heated non-combustible tobacco or non-tobacco-based products, and electronic vapor products, such as liquid-based cartridges. Aerosol-generating articles can be nicotine-containing product (NCP) cartridges or tobacco sticks. Aerosol-generating articles can be particularly adapted to aerosol-generating devices and can be configured to be inserted into the aerosol-generating article receiving cavity of the main body to generate aerosols.

[0127] The term heater applies to any article or unit configured to heat an aerosol-generating article received in a receiving cavity of an aerosol-generating article. Heaters can include devices, systems, and arrangements that allow the aerosol-forming material of the article to be aerosolized, such as external Joule or resistance heaters, external induction heaters (e.g., a sensor tube or sleeve inductively heated by one or more coils), internal Joule or resistance heaters (e.g., penetrating heater plates or needles), internal induction heaters (e.g., sensors inside the article, or sensors in the shape of penetrating plates or needles, both inductively coupled to one or more heating coils), infrared heat sources, radiative heaters (e.g., microwave-based), air heaters for air intake, and so on. Thus, a heater can generate heat remotely from the aerosol-generating article and transfer heat to the aerosol-generating article, for example, by conduction or convection, or can generate heat within the aerosol-generating article, for example, by induction, wherein a device generates a magnetic field that heats a metal or magnetizable element inside the aerosol-generating article, the metal or magnetizable element being positioned within the magnetic field to convert magnetic energy into heat. Heaters can also be dielectric heaters or infrared heaters. The heater can be disposed in at least one of the main body and the aerosol generating article to be received in the receiving cavity of the aerosol generating article. The heater can also be disposed in the key unit, or it can be disposed elsewhere.

[0128] The term actuator applies to any article or unit that may cause the heater to operate. An actuator can generate and transmit a signal to a controller, which causes the heater to operate. An actuator can be a purely mechanical device that can be actuated to allow operation of an aerosol generating device, such as a mechanical switch, push rod, or other mechanical device that can close a circuit to allow operation (e.g., to allow the heater to operate). In this sense, no trigger signal is generated; rather, the circuit is closed to make it operable. An actuator can be an active trigger, such as an on / off switch or button pressed by a user when the user expects to consume the aerosol generated by the aerosol generating device. An actuator can also be embodied as a passive trigger, where, for example, a sensor detects the presence of the aerosol generating article in the aerosol generating article receiving cavity and an attempt by the user to aspirate the aerosol from the aerosol generating article, and thus transmits a signal to the controller to cause the heater to operate. Thus, an actuator embodied as an active trigger may require input from the user to cause the heater to operate. An actuator embodied as a passive trigger may or may not require input from the user to cause the heater to operate, but it may include a sensor that detects or anticipates the user's intention to aspirate the aerosol.

[0129] The term battery compartment refers to a compartment that may include (or can be configured to receive) batteries (particularly primary or rechargeable batteries). Batteries may be temporarily received or permanently installed in the battery compartment. The battery compartment may be integrally formed with the rest of the body or detachable to allow for the replacement and remote charging of the batteries housed therein.

[0130] The term "body" refers to a physical entity that includes an actuator and an aerosol generating article receiving cavity, and preferably includes at least one of a heater and a battery (compartment). Since the aerosol generating article may include at least one of a heater and a battery or battery compartment, not all of these parts need to be housed within the body. The body can be a single, integral body or a body composed of several separable units. The body can have a cylindrical shape. The aerosol generating article receiving cavity can be located at the axial end of the cylindrical body and can be arranged concentrically with respect to the main axis of the cylindrical body. Alternatively, the body can have a curved droplet shape as seen in the direction in which the aerosol generating article is inserted into the aerosol generating article receiving cavity and / or in a cross-sectional view orthogonal to the axis of the aerosol generating article receiving cavity. The curved droplet shape may have a semi-circular portion and a tapering portion that tapers towards a distal portion. The tapering portion may have concave sidewalls and convex sidewalls.

[0131] The invention is defined in the claims. However, a non-exhaustive list of non-limiting examples is provided below. Any one or more features of these examples may be combined with any one or more features of another example, embodiment, or aspect described herein.

[0132] Example Ex1: An aerosol generating apparatus includes a body having an aerosol generating article receiving cavity and an actuator. The aerosol generating apparatus further includes a key unit detachably attached to the body, wherein detachment of the key unit from the body switches the apparatus from an operational state to a non-operating state.

[0244] First embodiment ( Figures 1 to 14 , Figure 16 , Figure 17 )

[0245] Overall

[0246] This invention relates to an aerosol generating apparatus. Such apparatus can be used to generate aerosols from tobacco or non-tobacco-based products and electronic vapor products (such as liquid-based cartridges), and is particularly useful for the aerosolization of nicotine-containing substances, for example via heated tobacco products (HTP) or heated non-burning (HNB) technologies.

[0247] Main Body 2

[0248] The device includes a body 2 having an aerosol-generating article receiving cavity 29, an actuator, a heater 28, and at least one battery compartment 23. Alternatively, the aerosol-generating article 8 (9) to be received in the aerosol-generating article receiving cavity 29 may include the heater 28 and / or at least one battery compartment 23. Therefore, the body 2 does not necessarily include all of these parts. The body 2 may be a single integral body, or it may consist of two or more separate bodies that can be detached from and attached to each other. For example, the battery compartment may be integrally formed within the body 2, or it may be separable from the rest of the body 2 such that it forms part of the body 2 in the attached state.

[0249] Figures 1 to 14 , Figure 16 and Figure 17 The main body 2 of the device according to the first embodiment is depicted, which has a curved droplet shape as seen in the top view in the direction in which the aerosol generating article 8 is inserted into the aerosol generating article receiving cavity 29. The curved droplet shape of the main body 2 is also visible in a cross-sectional view orthogonal to the axis of the aerosol generating article receiving cavity 29 (see [link]).Figure 3 a and Figure 3 b). The curved droplet shape of the main body 2 has a semi-circular portion and a tapering portion that tapers towards the distal end. The tapering portion has concave sidewalls and convex sidewalls. Due to the curved droplet shape, the device fits better in the user's hand, providing a secure grip.

[0250] The geometry and dimensional proportions are described in the following dimension table by range and preferred range:

[0251] Table 1: Dimensions of Main Body 2

[0252] The main body 2 of the second embodiment ( Figure 15 )

[0253] The second embodiment has a cylindrical body 2, wherein the aerosol generation article receiving cavity 29 is located at the axial end of the cylindrical body 2 and is arranged concentrically with respect to the cylindrical / main axis of the body 2. The key unit 200 is shaped to fit the shape of the body 2, having a protruding semi-cylindrical outer side and a recessed semi-cylindrical inner side that fits tightly to the outer side of the cylindrical body 2 in the operating state. Apart from this, the second embodiment has the same structural and functional features as the first embodiment, which are indicated by the same reference numerals.

[0254] Key unit 200

[0255] Adjacent to the main body 2, the aerosol generating device also includes a key unit 200 detachably attached to the main body 2. Detachment of the (attached) key unit 200 from the main body 2 switches the device from an operating state to a non-operating state. In the operating state, actuation of the actuator operates the heater 28 to heat the aerosol generating article 8 received in the cavity 29 to generate aerosol. In the non-operating state, the device cannot generate and / or release aerosol. Conversely, attachment of the key unit 200 to the main body 2 switches the device from a non-operating state to an operating state. Thus, the aerosol generating device is either operating or non-operating depending on whether the key unit 200 is attached to the main body 2. The key unit 200 thus functions like a key, preventing unauthorized and unattended use of the aerosol generating device (especially by children or infants). The key unit 200 may be a decorative shell or cover, but its decorative aspect is subordinate to its security aspects. In its simplest version, key unit 200 constitutes a simple mechanical key without any electronic components or other moving parts and / or any decoration. In more advanced versions, key unit 200 may include, for example, identification items (such as ID tags), and / or may be customized to achieve at least one decorative element that provides a pleasing and recognizable appearance.

[0256] Interaction between main body 2 and key unit 200

[0257] To simplify the detachable attachment of the key unit 200 to the main body 2, the main body 2 includes a keyhole 220, and the key unit 200 includes a corresponding key portion 201 that engages in the keyhole 220 during operation. In the non-operational state, the keyhole 220 allows fluid communication between the external environment and the aerosol generation article receiving cavity 29, thereby allowing air to reach or escape from the aerosol generation article receiving cavity 29 through the open keyhole 220.

[0258] The key portion 201 has a substance-containing article receiving cavity 202, which is configured to receive the substance-containing article 10 in a non-operating state and hold the substance-containing article to release its substance in an operating state to generate a modified aerosol. In use, the substance-containing article 10 releases its substance into the aerosol-generating article receiving cavity 29, particularly to the upstream end of the aerosol-generating article receiving cavity, or to the aerosol-generating article 8 received in the aerosol-generating article receiving cavity, or to the aerosol generated by the aerosol-generating device, or to the gas flow used to generate the aerosol.

[0259] The keyhole 220 is provided in the convex surface on the edge of the main body 2, in the height direction H of the main body 2 (see...). Figure 1 The keyhole 220 is located in the middle third of the central portion of the keyhole 220. The keyhole 220 has a slit-shaped opening. The inner cross-sectional shape of the keyhole 220 is adapted to / complementary to the outer cross-sectional shape of the key portion 201 in the direction in which the key portion 201 is inserted into the keyhole 220.

[0260] The key portion 201 protrudes from the concave side of the key unit 200 in an orthogonal direction. The top and bottom surfaces of the key portion 201 are coated with a layer 204 of an elastomeric material (such as an FDA-approved silicone-based polymer compound) to ensure an airtight seal of the keyhole 220 in the operational state. With this configuration, the key portion 201 separates the aerosol generation article receiving chamber 29 from the air inlet chamber located in the main body 2. This structure forces air to flow from the air inlet chamber through the air passage 203 located in the key portion 201 before entering the aerosol generation article receiving chamber 29. The upstream air passage 222 leads from the external environment to the air inlet chamber and the keyhole 220 of the receiving key element 201. Figure 9 and Figure 10The upstream air passage 222 is shown in dashed lines. The upstream air passage 222 forms part of an air intake structure that, in the operational state, supplies air to the aerosol-generating article receiving cavity 29 via an air passage 203 disposed in the key portion 201. The air passage 203 leads to the article-containing cavity 202 of the key portion 201. Thus, any air passing through the air passage 203, for example, due to a user drawing air onto the aerosol-generating article 8 received in the aerosol-generating article receiving cavity 29, flows through the article-containing article 10 received in the article-containing cavity 202 before entering the aerosol-generating article receiving cavity 29. The diameter of the air passage 203 can be selected in the range of about 0.1 to 2 mm, wherein the diameter of the air passage 203 is preferably constant along its length. In the operational state, the key portion 201 defines the bottom of the aerosol-generating article receiving cavity 29 and guides / forces air entering the cavity 29 to flow through the aerosol-generating article 8 received therein.

[0261] like Figure 11 As shown in (b), the key portion 201 supports the insertion end of the aerosol generating article 8 received in the aerosol generating article receiving cavity 29 in the operating state, so that the heater 28 can heat the aerosol generating substance contained in the aerosol generating article 8 to generate an aerosol. Figure 11 As shown in (c), the disassembly of the key unit 200 from the main body 2 causes the same aerosol generating article 8 to be improperly positioned relative to the heater 28 in the aerosol generating chamber 29 to prevent the aerosol generating substance contained in the aerosol generating article 8 from being heated by the heater 28, so that even if heated, no aerosol is generated or the aerosol generation is insufficient.

[0262] Therefore, the key unit 200, having its key portion 220, is a core functional part for operating the device, particularly a core functional part for the device's air management. For example... Figure 6 and Figures 8-13 As shown, the key unit 200 defines at least a portion of the airflow passage 202 and the air intake structure, which supplies air to the aerosol generation chamber 29 when the device is in operation.

[0263] Detection unit (e.g., pressure sensor 221).

[0264] The device may also include a detection unit to detect attachment / removal of the key unit 200 from the body 2. A controller (not shown) may be configured to switch the aerosol generating device to an operational state when attachment of the key unit 200 is detected, and to switch the device to a non-operational state when removal of the key unit 200 is detected. The detection unit may include a presence sensor or a distance sensor, which may be a capacitive sensor, an optical sensor, or an inductive sensor, etc. Alternatively, the detection unit may be embodied as a pressure sensor 221, which is pressed by the key portion 201 of the key unit 200 when the key unit 200 is attached and not pressed when the key unit 200 is removed. The pressure sensor 221 may include a spring pin or a button, for example, as... Figure 6 and Figures 8-13 As shown in the diagram, the detection unit can be used as an additional tamper-proof security feature to prevent unauthorized use of the device without the key unit 200 being attached to the main body 2.

[0265] Decorative elements of key unit 200

[0266] As a customizable item, the key unit 200 includes decorative elements, such as a shell or cover that remains visible in the operational state. As shown, the decorative elements of the key unit 200, or a portion of the key unit 200 including decorative elements, extend substantially orthogonally relative to the key portion 201 and cover the convex surface of the body 2 over the entire height H of the body. The decorative elements have decorative surfaces on their convex sides, which have decorative printing (texture or color), such as snakeskin fabric or gray carbon fiber that is adhesively attached, bonded, welded, or soft-soldered thereto. The entire key unit 200, and especially the decorative elements with their large extensions, can be made of metal and / or plastic.

[0267] To ensure a secure fit on the main body 2, the key unit 200 can be embodied as a resiliently deformable bracket. This resiliently deformable bracket can be detachably attached to the main body 2 without the need for tools by means of a shape-fitting mechanism, particularly by a snap-fit. For example, as... Figure 5 (d) and (e) and Figure 7 As shown in (d), (e), and (f), the key unit 200, in its operational state, surrounds two opposing edges of the body 2 along its length L. Due to its elastic deformability, the key unit 200, particularly its decorative elements, can expand to detach from the body 2 and retract to attach to the body 2 by clamping. The curvature and dimensions of the decorative elements of the key unit 200 are adapted to the curvature and dimensions of the convex side of the body 2, such that the concave side of the key unit 200 facing the body 2 fits tightly against the convex side of the body 2 in its operational state and is in complete contact with the body 2 without any gaps therebetween (see details). Figure 6 a andFigure 7 d).

[0268] Second key unit

[0269] like Figure 5 As shown, the (identical) body 2 can be combined with different (second) key units 200, which are detachably attached to the body 2 in place of the standard (first) key unit 200, wherein the key units 200 may differ at least in their decorative elements 230. Sensors can identify which of the different key units 200 is attached to the body 2 and can switch the controller (ECU) 25 to a specific operating mode when attachment and identification of a particular key unit 200 are detected.

[0270] The system includes the device and the aerosol-generating product.

[0271] The system according to the invention includes an aerosol generating apparatus according to any of the foregoing examples, and at least one aerosol generating article 8, the at least one aerosol generating article being configured to be received in an aerosol generating article receiving cavity 29 so as to generate an aerosol when the article is heated by a heater 28 in an operational state.

[0272] In operation, a static pressure difference (representing suction resistance (RTD)) exists between the two ends of the aerosol generating article 8 received in the aerosol generating article receiving cavity 29. The static pressure difference is measured according to ISO standard 6565:2002 when the aerosol generating article is passed through by an airflow of 15 under steady conditions, with any ventilation blocked, wherein the volumetric flow rate at the output end can be approximately 17.5 ml + / - 50% / s.

[0273] The aerosol generating article 8 of this system is specially designed and sized to fit into the aerosol generating article receiving cavity 29 provided in the main body 2, such that the key portion 201 holds the insertion end of the aerosol generating article 8 in an operational state and in the appropriate position, so that the heater 28 can heat the aerosol generating substance contained in the aerosol generating article 8 to generate aerosol.

[0274] The key unit 200 thus provides another safety feature, because its detachment from the main body 2 causes the same aerosol generating article 8 to be improperly positioned in the aerosol generating chamber 29, preventing the aerosol generating substance contained in the aerosol generating article 8 from being heated by the heater 28. Therefore, when the key unit 200 is not attached to the main body 2, even if the aerosol generating article 8 received in the aerosol generating chamber 29 is heated, no aerosol will be generated. The aerosol generating article 8 can be a nicotine-containing product (NCP) cartridge 9 or a tobacco stick 8.

[0275] Systems including apparatus, aerosol-generating articles, and articles containing substances.

[0276] Another system according to the invention further includes an aerosol generating apparatus and at least one substance-containing article 10, the at least one substance-containing article being configured to be held by a key unit 200 to interact with an aerosol generating article 8 received in an aerosol generating article receiving cavity 29 in an operational state in order to generate a modified aerosol.

[0277] This invention contemplates and describes a novel consumable 10 having a geometry that matches a cavity 202 present in the key portion 201 of the key unit 200 for retaining the consumable. Such a consumable 10 may be made of a porous matrix comprising a substance, such as a sensory medium that releases flavorings and aromas. However, the consumable 10 is not limited to containing flavored substances. Alternatively, the consumable 10 may contain pharmaceutical ingredients, plant-derived materials, etc.

[0278] The material-containing article 10 (also referred to as a consumable) may include several types of substances and different properties, such as those represented by exemplary consumables 101, 102, and 103. Consumers can obtain such material-containing articles 10 with different substances in stores, enhancing the sensory aspects of each consumer experience. Such consumables 10 are envisioned for a lasting effect and can last for approximately one week, depending on each consumer's use / consumption of the consumable 10.

[0279] Consumable 10 can be made of several types of porous materials, namely ceramic compounds, because they are commercially available for use, for example, in devices for releasing fragrance into the environment and for aromatherapy. These are material compounds selected from silicon carbide, silicon-based compounds, cordierite, silica, and zirconium-based ceramic compounds, as such compounds for this purpose are known to meet specifications for aerosolization applications of inhaled aerosols. These compounds are also known to be suitable for sintering in terms of particle size to obtain a desired porosity range, such as porous silica ceramics typically produced by the silica spinning solution industry, where silica particles are introduced by electrospinning and then subjected to sintering to obtain the final desired geometry and size, also achieving the desired porosity. The sintering process is typically carried out at temperatures of about 1000°C to 1200°C, and therefore, such materials meet the highest standards in terms of their end use in many applications, including FDA-approved materials for food and beverage and medical devices. The porosity of such materials is approximately 30% to 80%, preferably approximately 40% to 70%, and most preferably approximately 50% to 60%. Furthermore, the porosity of the sintered material can be adjusted by changing the content and particle size of the introduced silica particles, allowing for precise control over the desired porosity in the final product. Given the pore volume (Vp) and total volume (Vt) of a material with a defined volume, the porosity mentioned is given as a decimal value using standard methods and formulas. Therefore, the porosity (Pt) is given by the ratio Vp / Vt. To express the porosity as a percentage, this decimal is simply multiplied by 100%. For example, Pt = 0.51, therefore 0.51 x 100% = 51%.

[0280] In line with the trend of considering sustainability, natural materials can also be used to design and manufacture sustainable consumables10, namely, porous basalt-based materials, granulated natural open-pore porous stone available on the market, and combinations of these materials with silicon-based compounds, as both are commonly used in the production of sintered porous products and can match the required characteristics in terms of porosity and pore size as previously specified, as well as meet FDA requirements for food, beverage and medical devices.

[0281] The geometry and dimensional proportions of consumable 10 are described in the following dimension table by range and preferred range.

[0282] Table 2: Size Chart for Consumable 10

[0283] Method of operating an aerosol generating device

[0284] The method of operating the aerosol generating device according to any of the foregoing examples further includes, preferably, the following steps in the order ABCD or BACD:

[0285] Step A: Attach the key unit 200 to the main body 2 so that the device can be switched from the non-operational state to the operational state.

[0286] Step B: Receive the aerosol generating article 8 in the aerosol generating article receiving cavity 29.

[0287] Step C: Actuate the actuator to operate the heater 28 to heat the aerosol generating article 8 received in the aerosol generating article receiving chamber 29 to generate aerosol.

[0288] Step D: Remove the key unit 200 from the main body 2 so that the device can be switched from the non-operational state to the operational state.

[0289] Step A may also include: inserting the article containing material 10 into the article containing material receiving cavity 202 in the key portion 201 of the key unit 200 before attaching the key unit 200 to the main body 2.

[0290] Step C may also include: using the key portion 201 to keep the substance-containing article 10 interacting with the aerosol-generating article 8 to generate a modified aerosol.

[0291] Execution Summary of Preferred Embodiments

[0292] The benefits of this invention can be summarized as follows:

[0293] In the preferred embodiment of the invention described above, the aerosol generating device is designed to include a key unit 200 embodied as a removable / replaceable cover / shell. This key unit 200 includes a key portion 201 shaped as a protruding element, which is a core functional part of the device's air management. More specifically, the key portion 201 is a core functional part of the airflow channel and air intake structure that supplies air to the aerosolization chamber (i.e., the aerosol generating article receiving cavity 29), including controlling the suction resistance (RTD). The key portion 201 includes a cavity 202 for inserting a consumable 10 made of a porous medium impregnated with a substance (such as a flavoring agent, a drug, plant-derived material, or other substance). Thus, by removing the key unit 200 from the main body 2, the consumer ensures that the device is neither operational nor functional under any circumstances.

[0294] Size and details

[0295] From top to bottom, the main body 2 has a rounded shape (approximately 18 mm in diameter), and the aerosol generation article receiving cavity 29 for the aerosol generation article 8 (tobacco stick) is located at said rounded shape. Two such complementary shapes joined together will form an ellipse divided by an S-curve. Because one of these shapes must fit the other when rotated 180 degrees, the presence at the top of the shape must be reflected by the absence at the bottom. Starting from the extrusion protrusion, it will slightly widen to form a convex curve until the middle of the product (where the internal shape will taper), forming a curve ending at a dot.

[0296] Ergonomics

[0297] The aerosol generating device's natural shape, and particularly the so-called curved droplet shape of the main body 2, is specifically designed to be held in the consumer's hand. The convex shape follows the natural curve of the palm, allowing it to be held comfortably. This isn't the only way to hold it, as the thicker end of the device is perfectly shaped for the groove (tiger's mouth) between the consumer's thumb and forefinger. This allows the user flexibility depending on the situation they are in when they want to use the device. With its long, flat base, it is also very stable and easier to place upright. Consumers don't need to worry about their device tipping over. Its design also allows users to place it horizontally without worrying about their device rolling away.

[0298] Aesthetically pleasing

[0299] The shape of the aerosol generating device, and especially the shape of the main body 2, utilizes organic curves and follows the golden ratio to a certain extent (which is visible in mathematics, nature and is considered aesthetically pleasing).

[0300] The shape of Body 2 also makes it appear lighter than it actually is. Making full use of space, the finest part of Body 2 gives it a stylish and elegant construction, and creates the illusion of being smaller than it actually is.

[0301] Child safety

[0302] The device has a key unit 200 configured as a removable / replaceable cover / shell and includes a protruding key portion 201, i.e., an element that is a core functional part of the device's air management (including control of suction resistance (RTD)). The key portion 201 also includes a cavity 202 for inserting a consumable 10 made of a porous medium impregnated with flavoring substances or containing medicinal, plant-derived ingredients. Thus, by removing the key unit 200, the consumer can ensure that the device is inoperable and does not function under any circumstances.

[0303] As previously mentioned, the airflow required to supply the aerosolization chamber is driven by the user's suction and the intake of the overall airflow in opening 203, which also controls the suction resistance (RTD). In the operating state, the RTD can be in the range of 10 to 150 mmWG (millimeters of water column), more preferably 20 to 140 mmWG, and even more preferably 30 to 120 mmWG. In the non-operating state, an additional fluid connection is created from the aerosol-generating article receiving chamber to the external environment through an unoccupied keyhole, allowing the RTD to decrease to values ​​below 30 mmWG, preferably below 20 mmWG, and more preferably below 10 mmWG.

[0304] This aspect of the air passage 203 for controlling suction resistance (RTD) present in the key portion 201 of the key unit 200 is a fundamental functional aspect of this innovation, which incorporates a specific design of the key portion 201 that produces the overall geometry and volume of air management upstream of the aerosolization zone.

[0305] Therefore, independent of other aspects (such as the fact that the key portion 201 is also powered on and off via the microswitch 221), it is clear that once the key unit 200 is removed from the main body 2, the device becomes completely inoperable because it loses the core of the air management function, and even if someone attempts to insert the consumable 8 into the cavity 29, the consumable 8 will always be misaligned inside the cavity 29 because the key portion 201 also acts as a stop and the bottom portion of the cavity 29.

[0306] Release of substances (e.g., flavor compounds and aromas).

[0307] The general embodiment of the device with the removable key unit 200 includes the feature of releasing substances during the consumption of a primary consumable (aerosol-generating article 8, such as an HTP bar), while retaining the released substances (such as flavorings / fragrances) when the device is not in operation. These features are achieved through the special design of the device body 2 and the special key unit 200 when a specific consumable 10 is used to release substances (such as flavorings, fragrances and aromas, pharmaceuticals, or substances derived from plants).

[0308] Attachment Possibilities

[0309] like Figure 16 and Figure 17 As shown, the ecosystem may include geometrically paired NCP devices (which also serve as charger 6), as well as Bluetooth speaker unit 5 and wireless charger unit 4.

[0310] The device will have the possibility of being customized with a key unit 200 that can be embodied as a removable or replaceable cover or shell. The shell can be a magnetically bent structure that can fit perfectly into the convex external bent structure of the body 2, and can have any number of textures or colors adhered to it (e.g., snakeskin fabric, gray carbon fiber). This will allow users to match their device with their clothing or events in many different ways, and opens up the potential for data transfer or collectible "special edition" key units 200.

[0311] Expected Function

[0312] The device's unique shape provides sufficient volumetric space to include all the functions expected of operating the device at high performance, including:

[0313] The key unit 200 may be a removable or replaceable cover or shell that can be selected by the consumer based on the aesthetics of the cover, and when removed, it provides child safety features based on a specific key portion 201 of the core part constituting the air management and aerosolization chamber (aerosol generation article receiving cavity 29) of the device, and its control device has a suction resistance (RTD). In this way, the consumer only needs to remove such a key unit 200, and any use of the device in terms of electrical, mechanical, and air management functions is completely disabled.

[0314] The cavity 202 in the key portion 201 of the key unit 200 enables the consumable 10 to be used for the purpose of releasing substances (such as flavorings, fragrances or aromatics, drugs or materials derived from plants) into the intake air, and thus obtains an enhanced sensory experience during the consumption of the main HTP / HNB consumable for nicotine delivery.

[0315] The presence of consumable 10 in the cavity 202 of the key portion 201 of the key unit 200 creates conditions for the release of substances (e.g., fragrances / aromatics) when the device is not in operation, and thus keeps the device in a state of comfortable and pleasant storage and handling.

[0316] The core of innovation:

[0317] An aerosol generating device includes a cover / shell that can be assembled and disassembled by a consumer and has protruding elements that mechanically and functionally engage with the body of the device and the core of its aerosolization engine. In this way, once the cover / shell is removed, the device is completely disabled functionally.

[0318] The aerosol generating device described above includes a cavity in its protruding element for inserting and retaining consumables. Such protruding elements are mechanically and functionally engaged with the body of the device. These consumables release flavor compounds during aerosolization and normal operation of the device to enhance the consumer experience.

[0319] As described above, when the aerosol generating device is not operated for aerosolization, the aerosol generating device maintains the release of fragrance from consumables, and such consumables maintain the release of fragrance / aromatic agents through natural evaporation.
