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 Art

[0002] In the use of portable devices for the purpose of inhaling entertainment and nicotine-containing aerosols, there is a tendency for regulations and laws to be applied towards child protection.

[0003] Currently, there is no device in the market having an effective technical child-proof solution.

[0004] Also, devices for aerosolizing nicotine-containing substances, i.e., devices via heated tobacco products (HTP) or heat-not-burn (HNB) technology, are known to sometimes lack flavor and aroma notes compared to, for example, conventional products that can be combined with other consumable products such as flavorants, CBD, vaping systems, and inhalable pharmaceutical products. Therefore, it would be desirable for the device to incorporate additional flavor release that may enhance the overall consumer experience within the scope of aerosolization of HTP / HNB products.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Current aerosol generating devices in the market may be used by its owner, i.e., when the device is left unattended, by unauthorized users, which may include attempts of use by underage users including children. For example, a consumer may leave an aerosol generating device and the corresponding aerosol generating article at different locations in the home when at home, and thus, underage users including the consumer's children may attempt to use the aerosol generating device in numerous ways.

[0006] There is a growing trend toward stricter regulatory frameworks within the scope of childproof features for nicotine delivery devices and products, and therefore, technological solutions to prevent the use of aerosol generators and products by underage users are seen as strategic for businesses.

[0007] In parallel, it is desirable to provide users with the possibility to modify or otherwise alter the flavor of inhalable aerosols derived from consumables, such as tobacco-derived consumables, by using additional flavor-releasing consumables.

[0008] In summary, the problem to be solved is to provide an aerosol generator that incorporates a childproof solution. It would also be desirable to allow the release of a pleasant aroma to suppress potential residual odors inside the device, as well as to enhance the consumer experience by releasing flavors. [Means for solving the problem]

[0009] To solve the problems identified above, the present invention provides an aerosol generator as described in claim 1. Preferred embodiments are claimed in the dependent claims.

[0010] According to one aspect of the present invention, an aerosol generating device is provided, comprising a main body having an aerosol generating article receiving cavity and an actuator. The aerosol generating device further comprises a key unit that can be detachably attached to the main body, the removal of of the key unit from the main body switches the device from an operating state in which the operation of the actuator enables the operation of a heater to heat the aerosol generating article received in the cavity and generate an aerosol, to a non-operating state in which the device cannot generate and / or release an aerosol, and the attachment of the key unit to the main body switches the device from the non-operating state to the operating state. The main body or aerosol generating article used in combination with the device may further comprise a heater and a battery (compartment). Alternatively, the main body may comprise one of the heater and the battery, while the aerosol generating article comprises the other of the heater and the battery.

[0011] Thus, the aerosol generator becomes operational or inoperable depending on whether the key unit is attached to the main body. The key unit then functions as a childproof lock. For example, it acts like a key to prevent unauthorized and unmanned use of the aerosol generator, particularly by children or infants. This safety feature can meet current market and regulatory demands for childproof technical solutions for portable aerosol generators.

[0012] According to claim 1, attaching / detaching the key unit to / from the main body simply switches the device between an operating state and a non-operating state, respectively. This may include, for example, sensors and controllers, any indirect causal relationship between attachment / detachment and switching.

[0013] More specifically, a key unit is an additional component adjacent to the main body. In the absence of any further functional, technical, or electrical requirements, a key unit may be an inexpensive, lightweight, simple, and decoratively customizable item that can be purchased separately from the main body. Heaters, battery compartments, and actuators themselves are not eligible as key units because they increase their cost, size, and weight, as well as being designed and built according to specific functional, technical, and / or electrical requirements that require complex mechanical and electrical interfaces.

[0014] Mechanical key (Claim 2) In a preferred embodiment, the key unit is a mechanical key that, upon removal from the main body, mechanically switches the device from an operating state to a non-operating state, and upon attachment to the main body, mechanically switches the device from a non-operating state to an operating state, wherein the key unit preferably has no electronic components or other active components. This allows for a very simple, inexpensive, and lightweight design of the key unit, as well as easy attachment to and removal from the main body. Claim 2 specifies that the attachment / detachment of the key unit to / from the main body switches the device to an operating state / non-operating state, meaning that the attachment / detachment of the key unit to / from the main body has a direct / active causal relationship with the switching of the device to an operating state / non-operating state.

[0015] The key unit connects (disconnects) the battery and heater (Claim 3) In another preferred embodiment, removal of the key unit from the main body may cause an electrical disconnection of the heater from the battery (specifically, a battery provided in or received within the battery compartment), and attachment of the key unit to the main body may cause an electrical connection of the heater to the battery.

[0016] As a result, depending on whether the key unit is attached to the main body, there may or may not be an electrically operational connection between the battery and the heater. Without power from the battery, the heater cannot heat the aerosol-generating article received in the aerosol-generating article receiving cavity, and thus aerosol generation is effectively prevented in the inoperable state. On the other hand, the attachment of the key unit to the main body establishes an electrical connection between the battery and the heater, so aerosol generation is only possible in the operating state.

[0017] The interaction of the key unit with the electrical connection between the battery and the heater provides an additional safety feature that prevents unauthorized use of the aerosol generator, in that removing the key unit from the main body electrically disables the operation of the aerosol generator.

[0018] The key unit affects the airflow within the cavity (Claim 4) In another preferred embodiment, removal of the key unit from the main body may worsen or disable the airflow inside the aerosol-generating article receiving cavity, thereby preventing the device from generating and / or releasing aerosols, while attachment of the key unit to the main body may improve or enable the airflow inside the aerosol-generating article receiving cavity, thereby enabling the device to generate and / or release aerosols. The aerosols generated by the device may be delivered to the user or consumer via a mouthpiece.

[0019] More specifically, the removal of the key unit from the main body may open the aerosol generating article receiving cavity, specifically its upstream end, and fluidly connect it to the open air, so that the user cannot extract the aerosol generated from the aerosol generating article. Alternatively, the attachment of the key unit to the main body may close the aerosol generating article receiving cavity, specifically its upstream end, and deconnect the aerosol generating article receiving cavity from the open air. The upstream end of the aerosol generating article receiving cavity is where the insertion end of the aerosol generating article received in the aerosol generating article receiving cavity is located during aerosol generation. This end of the aerosol generating article receiving cavity is called the upstream end because it is located upstream of the aerosol generating article during aerosol consumption by the user. The airflow through the aerosol generating article received in the aerosol generating article receiving cavity may be triggered by the user's inhalation. The airflow begins at the insertion end of the aerosol-generating article and then passes through the entire article to generate aerosols. The aerosols generated, for example by distributing heated tobacco particles into the airflow passing through the article, leave the article through the end located outside the aerosol-generating article receiving cavity.

[0020] The key unit, specifically its key portion, may be a core functional part for operating the device, specifically a core functional part for air management of the device, and the key unit may define at least a portion of the airflow channel and air intake structure that feeds into the aerosol generation cavity when the device is operating.

[0021] An air intake chamber (or air reservoir) may be located at the upstream end of the aerosol-generating article receiving cavity. This air intake chamber may be filled with ambient air when the user is not inhaling aerosols from the aerosol-generating article received in the aerosol-generating article receiving cavity. There may be an upstream air channel connecting the air intake chamber and a keyhole portion receiving key elements from the external environment. The air volume and air resistance of the air intake chamber may be fluidically adapted to the user's typical smoke inhalation. When the user begins inhaling aerosols from the aerosol-generating article, air from the air intake chamber may flow into the aerosol-generating article. This creates a negative pressure within the air intake chamber or air reservoir that draws in ambient air from outside the device or the external environment as soon as the user stops inhaling aerosols from the aerosol-generating article. The limited air volume of the airflow arrangement in the air intake chamber and aerosol-generating article receiving cavity provides a specific draw-to-deadpoint (RTD). The draw-out resistance (RTD) may be controlled by the elements forming the aerosolization chamber to be within a specific defined range in the operating state. 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 to the external environment is created from the aerosol-generating article receiving cavity by an unoccupied keyhole, and therefore the RTD may decrease to a value of less than 30 mmWG, preferably less than 20 mmWG, and more preferably less than 10 mmWG.

[0022] The interaction of key units for modifying the airflow inside the aerosol-generating article receiving cavity provides yet another safety feature that prevents unauthorized use of the aerosol generator.

[0023] Detection unit (Claim 5) In yet another preferred embodiment, the device may further comprise a detection unit configured to detect the attachment and detachment of the key unit to / from the main body, and the detection unit may be configured to switch the device to an operating state upon detection of the attachment of the key unit, and also to switch the device to a non-operating state upon detection of the detachment of the key unit.

[0024] The detection unit may comprise a presence or distance sensor, and the presence or distance sensor may be a capacitance sensor, an optical sensor, an inductive sensor, or the like.

[0025] The detection unit may comprise 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 comprise a pogo pin or a push button.

[0026] The interaction of the key unit with the detection unit prevents unauthorized use of the aerosol generating device and provides another additional safety feature.

[0027] Keyhole and key part (Claim 6) In yet another preferred embodiment, the main body may comprise a keyhole, and the key unit may comprise a corresponding key part that fits into the keyhole to enable an operating state.

[0028] The keyhole may be in fluid communication with the aerosol generating article receiving cavity and the external environment in the non-operating state, allowing air from the external environment to reach into the aerosol generating article receiving cavity through the keyhole or allowing leakage from the aerosol generating article receiving cavity.

[0029] The keyhole may be closed, specifically hermetically sealed, against the external environment by the key unit in the operating state.

[0030] The key portion may be at least partially coated with a layer of elastomer material, such as an FDA-approved silicon-based polymer compound, preferably on its top and bottom surfaces, to provide a seal that may ensure an airtight seal of the keyhole in the operating state.

[0031] The keyhole may be provided within a convex surface of the main body.

[0032] The keyhole may be provided on the edge of the main body.

[0033] The keyhole may be provided in the central portion in the height and / or length and / or width direction of the main body, preferably in the middle third of the length and / or width and / or height of the main body.

[0034] The internal cross-sectional shape of the keyhole may be adapted to or complementary to the external cross-sectional shape of the key portion in the direction of insertion of the key portion.

[0035] The keyhole may have a slit-shaped opening.

[0036] The key portion may protrude from the concave side of the key unit.

[0037] The key portion may protrude from the decorative element of the key unit, specifically in a direction perpendicular to the decorative element.

[0038] In operation, the key portion may separate the aerosol-generating article receiving cavity from the air intake chamber provided within the main body, or it may force air to flow from the air intake chamber through the air passage provided within the key portion before entering the article receiving cavity.

[0039] The air passage may be opened into the material-containing article receiving cavity of the key portion so that the air passing through the air passage (triggered, for example, by the user's inhalation) flows through the material-containing article received in the material-containing article receiving cavity before entering the aerosol-generating article receiving cavity located downstream.

[0040] The air passage may be formed by a transverse hole or bore with a diameter of approximately 0.1 to 2 mm.

[0041] In operation, the key portion may guide air entering the aerosol-generating article receiving cavity so that it flows through the aerosol-generating article received therein.

[0042] In operation, the key portion may define the bottom of the aerosol-generating article receiving cavity.

[0043] The complementary and adapted shapes of the keyhole and key portion provide another additional safety feature, preventing unauthorized use of the aerosol generator by attempting to simulate the presence of a key portion and hindering the operation of the device by inserting a key-like item into the keyhole.

[0044] Decorative element (Claim 7) In another preferred embodiment, the key unit may include decorative elements that remain visible in the operating state.

[0045] A portion of the key unit, which includes decorative elements, may cover an exposed surface, preferably a convex surface, of the main body.

[0046] The decorative elements may include decorative surfaces, such as decorative patterns, one or more symbols, one or more logos, or a combination thereof.

[0047] Decorative elements may be walls, components, shells, or covers.

[0048] Decorative elements may include texture and color, patterns, embossing, perforation, and structure, such as at least one of snakeskin fabric or gray carbon fiber.

[0049] The decorative elements may be attached to the key unit with adhesive, joined, welded, soldered, or integrally formed with the key unit (e.g., by 3D printing).

[0050] A portion of the key unit that includes decorative elements may extend substantially perpendicular to the key portion of the key unit.

[0051] A portion of the key unit with decorative elements may occupy or cover at least one of the following dimensions on at least one side of the main body in operation: At least 50%, 70%, or 90%, preferably 100%, of the height dimension of the main body.

[0052] At least 50%, 70%, or 90%, preferably 100%, of the length dimension of the main body.

[0053] At least 50%, 70%, or 90%, preferably 100%, of the width dimension of the main body.

[0054] A key unit configured to hold a substance-containing article (Claim 8) In another preferred embodiment, the key unit, specifically the key portion thereof, may be configured in an operating state to hold a substance-containing article and release the substance to generate a modified aerosol.

[0055] The key unit may include a substance-containing article receiving cavity configured to receive a substance-containing article, preferably upstream from the aerosol-generating article receiving cavity.

[0056] The key unit may be configured to support a substance-containing article, thereby releasing the substance into an operating aerosol-generating article receiving cavity, specifically to its upstream end, or to an aerosol-generating article received therein, or to an aerosol generated by an aerosol generator, or to an airflow used to generate an aerosol.

[0057] Substance-containing articles may be flavored or fragrance-containing articles. The release of a pleasant flavor or fragrance may enhance the consumer experience.

[0058] Substance-containing articles may contain pharmaceutical ingredients, plants, CBD, etc.

[0059] Shape-fitting friction fitting (Claim 9) In another preferred embodiment, the key unit may be attached to the main body in a removable manner by morph-fit and / or magnetic force.

[0060] The key unit may be attached to the main body in a way that allows it to be removed by snap-fitting.

[0061] The key unit may receive two opposing edges of the main body in operation, or it may be arranged on the same plane.

[0062] The key unit may be configured to be attached to and removed from the main body without the use of tools.

[0063] The key unit may be elastically deformable for attachment to and removal from the main body.

[0064] The key unit may be configured to expand for removal from the main body, or to contract for attachment to the main body.

[0065] The key unit may be formed as a bracket.

[0066] The key unit may be attached to the main body by clip fastening.

[0067] The key unit may be made from metal and / or plastic.

[0068] The key unit may include an elastic body.

[0069] The key unit may cover at least one side of the main body over its entire width and / or length and / or height.

[0070] The side of the key unit facing the main body may be in complete contact with the main body without any gap when in operation.

[0071] The key unit may be fitted snugly into the main body when in operation.

[0072] The above features provide considerable flexibility for attaching / detaching the key unit to / from the main body.

[0073] A key unit configured to position an aerosol-generating article (Claim 10) In another preferred embodiment, the key unit may be configured to position the aerosol-generating article received in the aerosol-generating article receiving cavity, particularly with respect to the heater, when in operation.

[0074] The key portion may be configured to at least partially support the aerosol-generating article received within the aerosol-generating article receiving cavity, particularly at the tip of the aerosol-generating article, when in operation.

[0075] The key unit may be configured to position the aerosol-generating article received in the aerosol-generating article receiving cavity when in operation, thereby allowing the heater to heat the aerosol-generating substance contained within the aerosol-generating article and generate an aerosol. Removing the key unit from the main body may cause the same aerosol-generating article to be improperly positioned in the aerosol-generating cavity, preventing the aerosol-generating substance contained within the aerosol-generating article from being heated by the heater, and consequently resulting in no aerosol being generated, or only an insufficient aerosol being generated, despite heating.

[0076] As a result, the aerosol generating article can only be correctly positioned within the aerosol generating article receiving cavity when the key unit is attached to the main body. The absence of the key unit leads to mispositioning of the aerosol generating article within the aerosol generating article receiving cavity, specifically in relation to the heater or the airflow passing through the aerosol generating article receiving cavity. Consequently, the aerosol generating device becomes inoperable without the key unit due to the mispositioning of the aerosol generating article.

[0077] Second key unit (Claim 11) In another preferred embodiment, the device may further include a second key unit that can be detachably attached to the main body instead of the first key unit, and the first and second key units may differ at least in their decorative elements. The decorative elements may be used, for example, for personalization purposes.

[0078] The device may include a sensor configured to identify a first key unit and a second key unit, the sensor may be configured to switch the device to a first operating mode upon identification of the first key unit, and the sensor 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 sensor 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 further include a controller which may generate a first command to switch the device to a first operating mode upon receiving the first signal, and a second command to switch the device to a second operating mode upon receiving the second signal. This may be embodied, for example, by an RFID tag, an optical tag, a pattern or code, or by different mechanical structures of the first key unit and the second key unit.

[0079] A system comprising an aerosol generator and articles (Claim 12) According to another aspect of the present invention, a system is provided comprising an aerosol generating device according to any one of the preceding embodiments and embodiments, and at least one aerosol generating article configured to be received in an aerosol generating article receiving cavity so as the aerosol generating article is heated by a heater while in operation, the system generates an aerosol.

[0080] In the operating state, when measured according to ISO standard 6565:2002 with all ventilation blocked, the static pressure difference between the two ends of an aerosol-generating article received in the aerosol-generating article receiving cavity (representing the draw-out resistance (RTD)) may 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 to the external environment is created from the aerosol-generating article receiving cavity by an unoccupied keyhole, and therefore the RTD may decrease to a value of less than 30 mmWG, preferably less than 20 mmWG, and more preferably less than 10 mmWG.

[0081] The key portion may be configured to hold the aerosol-generating article, specifically its insertion end, in an operational state within the aerosol-generating article receiving cavity.

[0082] The key unit may be configured to position the aerosol-generating article received within the aerosol-generating cavity in the operating state, thereby allowing the heater to heat the aerosol-generating substance contained within the aerosol-generating article and generate an aerosol.

[0083] Removing the key unit from the main body may cause the same aerosol-generating article to be improperly positioned within the aerosol-generating cavity, preventing the aerosol-generating substance contained within the article from being heated by the heater. As a result, despite heating, no aerosol may be generated, or only an insufficient amount of aerosol may be generated.

[0084] The aerosol-generating article may be, but is not limited to, a nicotine-containing product (NCP) cartridge or a tobacco stick.

[0085] A system further comprising an article containing a substance (Claim 13) According to yet another aspect of the present invention, a system according to a prior embodiment is provided, further comprising at least one substance-containing article configured to be held by a key unit to interact with an aerosol-generating article received in an aerosol-generating article receiving cavity so as to generate a modified aerosol in an operating state.

[0086] The substance-containing article may be made from a porous medium or may contain a porous substrate.

[0087] Articles containing substances may incorporate sensory media to release flavors and aromas.

[0088] The substance-containing article may be in the shape of a disc, or it may be impregnated with a flavoring substance (in liquid and / or gel form).

[0089] The material-containing article may be one of the following types of porous materials: a) For example, ceramic compounds, such as those available on the market, are used to release fragrance not only in devices for ambient fragrance emission but also in devices for aromatherapy. b) Compounds of materials selected from silicon carbide, silicon-based compounds, cordierite, silica, and zirconium-based ceramic compounds. c) A suitable compound from the viewpoint of particle size analysis to obtain a desired range of porosity by sintering, such as a porous silicon ceramic industrially produced from a silica spinning solution, where silica particles are introduced by electrospinning, and then sintering is applied to obtain the final desired geometric shape and size, as well as the desired porosity. The sintering process may occur at a temperature of about 1000°C to 1200°C.

[0090] The substance-containing article may be a sintered porous product.

[0091] The porosity of the substance-containing article may be about 30-80%, preferably about 40-70%, and most preferably about 50-60%.

[0092] The porosity of the sintered material may be adjusted by changing the content of the introduced silica particles and altering its particle size analysis, which allows for good control of the desired porosity at the end of the process from the perspective of the final product.

[0093] The porosity referred to is given using a standard method and equation that gives a decimal value for porosity, knowing the volume of pores and the total volume (Vt) of a defined volume of material (Vp), where the porosity (Pt) is given by the ratio of Vp / Vt, and the porosity is expressed as a percentage, and its decimal is simply multiplied by 100%, for example, Pt = 0.51, therefore 0.51 × 100% = 51%.

[0094] The material-containing articles may be designed and manufactured using natural materials such as porous basaltic materials, granular natural open-cell porous stone materials available on the market, and combinations thereof with silica-based compounds, both of which are commonly used to produce sintered porous products.

[0095] Substance-containing articles may comply with FDA requirements for F&B and medical devices.

[0096] The set may further comprise at least two different substance-containing articles that differ in shape and / or substance. The substance-containing articles may contain at least one of the following: flavorings, plants, pharmaceutical products, cannabidiol (CBD), and similar substances.

[0097] A method for operating an aerosol generator (Claim 14) According to yet another aspect of the present invention, a method for operating an aerosol generator or system according to any of the prior aspects and embodiments is provided, comprising the following steps: Step A: Attach the key unit to the main body so that the device can be switched from a non-operational state to an operational state.

[0098] Step B: Receiving the aerosol-generating article into the aerosol-generating article receiving cavity.

[0099] Step C: Activate the actuator to trigger the heater to heat the aerosol-generating article received in the aerosol-generating article receiving cavity, thereby generating an aerosol.

[0100] Step D: This step preferably includes removing the key unit from the main body in the order ABCD or BACD, but is not necessarily in that order, in order to switch the device from an operating state to a non-operating state.

[0101] The preferred order of the steps is ABCD, but the steps may also be carried out in a different order, such as BACD.

[0102] A method for generating a modified aerosol (Claim 15) Step C may further include using the key portion to hold the substance-containing article and allow it to interact with the aerosol-generating article to generate a modified aerosol. The substance-containing article may be inserted into the substance-containing article receiving cavity of the key unit, specifically into the key portion of the key unit, before the key unit is attached to the main body.

[0103] Further preferred embodiments arise from combinations of features disclosed herein, in the claims, and in the drawings.

[0104] Terms and Definitions The term "aerosol generator" applies to all devices configured to generate aerosols. Aerosol generators may be portable or handheld devices. They may be operated remotely from the power grid and may be powered by batteries.

[0105] The term "aerosol generating article" applies to all articles that may be used to generate aerosols, such as heated non-combustible tobacco or non-tobacco-derived products, and to e-vaper products such as liquid-based cartridges. Aerosol generating articles may also be nicotine-containing product (NCP) cartridges or tobacco sticks. Aerosol generating articles may be specifically adapted for aerosol generating devices and may be configured to be inserted into an aerosol generating article receiving cavity in the main body to generate aerosols.

[0106] The term heater applies to any item or unit configured to heat an aerosol-generating article received within an aerosol-generating article receiving cavity. A heater may include, for example, an external Joule or resistance heater, an external induction heater such as a susceptor tube or sleeve inductively heated by one or more coils, an internal Joule or resistance heater such as a penetrating heater blade or needle, an internal induction heater such as a susceptor into the article, or a susceptor in the form of a penetrating blade or needle, both inductively coupled to one or more heating coils, infrared heating sources, radiant heaters, etc., based on microwaves, air heaters for incoming air, etc. Thus, a heater may generate heat remotely from the aerosol-generating article and transfer heat to the aerosol-generating article by conduction or convection, for example, or generate heat within the aerosol-generating article by induction, for example, the device generates a magnetic field that heats metal or magnetizable elements inside the aerosol-generating article positioned in the magnetic field to convert magnetic energy into heat. The heater may also be a dielectric heater or an infrared heater. The heater may be provided in at least one of the main body and the aerosol generating article received in the aerosol generating article receiving cavity. The heater may also be provided in the key unit or elsewhere.

[0107] The term actuator applies to any item or unit that may cause a heater to operate. An actuator may generate a signal that causes a heater to operate and transmit it to a controller. An actuator may be a purely mechanical device that can be operated to enable the operation of an aerosol generator, such as a mechanical switch, a push rod, or other mechanical means that can close an electrical circuit to enable operation, such as allowing a heater to operate. In this sense, no trigger is generated, but an electrical circuit is closed to enable operation. An actuator may also be an active trigger, such as an on / off switch or button that the user presses when they wish to consume the aerosol generated by the aerosol generator. An actuator can also be embodied as a passive trigger, for example, a sensor that detects not only the presence of an aerosol generator in an aerosol generator receiving cavity, but also a user attempt to inhale an aerosol from the aerosol generator, and then transmits a signal to a controller to cause the heater to operate. Thus, an actuator embodied as an active trigger may require user input to cause the heater to operate. The actuator, embodied as a passive trigger, may or may not require user input to trigger the heater's operation, and may instead include a sensor that detects or predicts the user's intention to aerosolize.

[0108] The term "battery compartment" refers to a compartment that may contain, or be configured to receive, batteries, specifically disposable or rechargeable batteries. Batteries may be temporarily received or permanently installed within the battery compartment. The battery compartment may be integrally formed with the rest of the main body or may be separable from the rest of the main body to allow for the replacement and remote charging of the batteries contained therein.

[0109] The term "main body" refers to an entity comprising an actuator and an aerosol generating article receiving cavity, and preferably at least one of a heater and a battery (compartment). Since the aerosol generating article may comprise at least one of the heater and battery or battery compartment, not all of these components need to be provided within the main body. The main body may be a single, integrated body or a body consisting of several separable units. The main body may have a cylindrical shape. The aerosol generating article receiving cavity may be located at the axial end of the cylindrical main body, or it may be arranged concentrically with respect to the main axis of the cylindrical main body. Alternatively, the main body may have a curved teardrop shape as seen in the direction of insertion of the aerosol generating article into the aerosol generating article receiving cavity and / or in a cross-sectional view perpendicular to the axis of the aerosol generating article receiving cavity. The curved teardrop shape may have a semicircular portion and a tapered portion that tapers from the semicircular portion toward the distal end portion. The tapered portion may have concave and convex sidewalls. [Brief explanation of the drawing]

[Figure 8] The diagrams show different components of the apparatus, where Figure 8(a) and Figure 8(b) are enlarged views of Figure 7(a) and Figure 7(b), and Figure 8(c) is a cross-sectional view of the apparatus mounted along line ZZ (as defined in Figures 7 and 8(b)), including details of the assembly of the key portion (201) when properly positioned inside the keyhole (220) within the main body (2). [Figure 9]Cross-sectional views of the components of the device in a detached state and in a state before installation (similar to Figure 6(b), but with different reference numerals), the key portion (201) of the key unit (200) and the keyhole (220) of the main body (2) are aligned for installation in a linear direction of movement along the longitudinal direction of the main body (2), and so the key portion (201) is in fact the key portion of the entire cavity and aerosolization chamber, and upon installation, the key portion (201) ensures a complete setup of the air management system, whereas without the key portion (201), there is no functional cavity, the cavity's opening is in open air, there is no air management, and therefore it does not function or can operate for aerosolization. [Figure 10] This is a cross-sectional view of the components of the device in an installed state (similar to Figure 8(c), but with different reference numerals), where the key portion (201) of the key unit (200) is received in the keyhole (220) to hermetically seal the aerosol generating article receiving cavity (29) to the outside of the main body (2), and the key portion (201) of the key unit (200) also presses a push button (221), such as a microswitch / pogo pin component, provided inside the keyhole (220) at the inner end of the keyhole (220), which also switches power to the aerosolizing engine on / off (regardless of its type, e.g., inductive or resistive), and thereby switches the device into an operating state. [Figure 11]A cross-sectional view of the components of the device showing specific functional features of the device resulting from the proper assembly of the key portion (201) and the main body (2), wherein Figures 11(a) and 11(b) show the situation when the key unit (200) is properly attached to the main body (2) using Figure 11(a) before and after insertion of the aerosol generating article (8) into the aerosol generating article receiving cavity (29), and Figure 11(c) shows the situation when the aerosol generating article (8) is inserted into the aerosol generating article receiving cavity (29) while the key unit (200) is removed from the main body (2), which renders the device inoperable. As the system switches and changes to an open air system, not only does it render the cavity (29) / aerosolizing chamber non-functional, but if someone attempts to insert a consumable (8) in the form of a tobacco rod, the consumable will stop in the wrong position and settle inside in a bad state, mispositioning the tobacco rod (8) outside the heating element (28), while there will be no proper airflow and proper draw-to-drain (RTD), and at the top, the microswitch (221) will not activate when the key portion (201) is not inserted into the keyhole (220) of the main body (2), which will automatically switch the power of the device off. [Figure 12] A consumable (10) is a disc-shaped porous consumable impregnated with a flavored substance (in liquid and / or gel form), which can be advantageously used when it is set in a cavity (202) of a key portion (201) of a key unit (200) and held inside the cavity (202) by dimensional tolerances and geometric characteristics (such as protruding elements in the side walls of the cavity (202), or other specific design details for such purposes), and when the key unit (200) is in place, the flavor-releasing consumable (10) is located at the bottom of the cavity (202) and thus releases the flavor into an air intake that leads to aerosol-generating article receiving cavity (29). [Figure 13]Figure 13(a) and Figure 13(b) show the state before and after insertion of the tobacco stick as an aerosol generating article (8) into the aerosol generating article receiving cavity (29). Figure 13(b) shows the air passage (203) of the key part (201) and the flavored consumable (10), as well as the heated tobacco stick (8), so that the flavor released from the flavored consumable (10) mixes with the aerosol released from the tobacco stick (8) in order to generate a flavored aerosol. Figure 13(c) is a perspective view of the device shown in Figure 13(b), and Figures 13(d), 13(e), and 13(f) are similar to Figures 13(a), 13(b), and 13(c), but instead of a tobacco stick, a nicotine-containing product (NCP) cartridge is used as the aerosol-generating article (8) received in the aerosol-generating article receiving cavity (29) of the device (2), and the functional configuration of the flavoring disc (10) is shown, with the air intake being enhanced with flavor towards the aerosol-generating zone / upstream of the aerosol-generating zone, and Figure 13(g) shows different side / perspective views of the NCP cartridge (9). [Figure 14] Exemplary embodiments of a consumable (10), including an aerosolized cavity (29), its geometric shape, and which may exist to optimize the aerosolization / volatilization mode of a substance contained therein, such as a flavoring agent impregnated within a porous structure that can exist in liquid and / or gel form, as well as its main geometric and design aspects. [Figure 15] This is a representation of a second embodiment of a cylindrical aerosol generator, including showing the innovation and its technical solutions in different designs, i.e., customized embodiments thereof as accessories in terms of different possible visual aspects, colors, and textures.

[Figure 17] A schematic perspective view of exemplary complementary devices of the Yin Yang Ecosystem, where Figure 17(a) illustrates a Bluetooth loudspeaker, Figure 17(b) shows a wireless charging unit (4), and Figure 17(c) illustrates an aerosol generator (2) and corresponding power charger device (6) according to Figure 16 in an interconnected state, docked to the wireless unit (4) in Figure 17(b). The complementary devices may be configured for different or the same type of consumables, for example, a heated non-combustible (HNB) and vaping combo, where one device heats the HNB consumable. The device is configured such that the other device is configured for vaporizing consumables / articles having a liquid, for example, a nicotine-containing liquid, and the complementary device may be a battery extension module, a battery charger device, a device having an internal compartment for detachably holding several consumables / sticks (e.g., a device having a rotating drum), a user interface device (e.g., a large display unit), or other type of device, and may also be a base cylindrical element as a holder / charger for two interconnected curved teardrop-shaped units. [Modes for carrying out the invention]

[0111] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The apparatus according to the first embodiment has an exemplary volumetric shape that, based on its particular shape, allows it to conform with other objects such as other devices and accessories to create an ecosystem.

[0112] However, the focus will shift to the aforementioned innovations as technical solutions to the referenced problems.

[0113] For the purposes of this specification and the appended claims, unless otherwise indicated, all numbers representing amounts, quantities, percentages, etc., are understood to be modified in all cases by the term “approximately.” Furthermore, all ranges include the disclosed maximum and minimum points and any intermediate ranges within them, which may or may not be specifically listed herein. Thus, in this context, number A is understood as A ± 10%. In this context, number A may be considered to include a number that falls within the general standard error of the measured value of the characteristic that number A modifies. In some cases used in the appended claims, number A may deviate by the percentages listed above, provided that the amount of deviation of A does not substantially affect the basic and novel characteristics of the claimed invention. Furthermore, all ranges include the disclosed maximum and minimum points and any intermediate ranges within them, which may or may not be specifically listed herein.

[0114] First embodiment (Figures 1-14, 16, 17) General characteristics The present invention relates to an aerosol generator. Such a generator may be used to generate aerosols from tobacco or non-tobacco-derived products and e-vapor products such as liquid-based cartridges, and specifically, for example, for the aerosolization of nicotine-containing substances via heated tobacco products (HTP) or heated non-combustion (HNB) technology.

[0115] Main body 2 The device comprises a main 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) received in the aerosol generating article receiving cavity 29 may include the heater 28 and / or at least one battery compartment 23. Therefore, the main body 2 does not need to include all of these components. The main body 2 may be a single, integrated body, or it may consist of two or more separate bodies that may be detached from each other and attached to each other. For example, the battery compartment may be integrally formed within the main body 2, or it may be detachable from the rest of the main body 2 so as to form part of the main body 2 when attached.

[0116] Figures 1-14, 16, and 17 illustrate the main body 2 of the device according to the first embodiment, which has a curved teardrop shape, as seen in a top view in the direction of insertion of the aerosol generating article 8 into the aerosol generating article receiving cavity 29. The curved teardrop shape of the main body 2 is also seen in a cross-sectional view perpendicular to the axis of the aerosol generating article receiving cavity 29 (see Figures 3a and 3b). The curved teardrop shape of the main body 2 has a semicircular portion and a tapered portion that tapers from the semicircular portion toward the distal end. The tapered portion has concave and convex side walls. Due to the curved teardrop shape, the device fits better in the user's hand and provides a secure grip.

[0117] Geometric and dimensional ratios are described in the dimension table below, in ranges and preferred ranges.

[0118] Table 1: Dimensions of Main Body 2 JPEG2026515952000002.jpg43170

[0119] Body 2 of the second embodiment (Figure 15) The main body 2 of the second embodiment has a cylindrical shape, and the aerosol generating article receiving cavity 29 is located at the axial end of the cylindrical main body 2 and is arranged concentrically with respect to the cylinder / main axis of the main body 2. The shape of the key unit 200 is adapted to the shape of the main body 2, insofar as it has not only a convex semi-cylindrical outer surface that fits snugly to the outer surface of the cylindrical main body 2 when in operation, but also a concave semi-cylindrical inner surface. Separately, the second embodiment has similar structural and functional features designated by the same reference numerals as the first embodiment.

[0120] Key unit 200 Following the main body 2, the aerosol generator further comprises a key unit 200 that is detachably attached to the main body 2. Removal of the (attached) key unit 200 from the main body 2 switches the device from an operating state, in which the actuator activates the heater 28 to heat the aerosol generating article 8 received in the cavity 29 and generate an aerosol, to a non-operating state, in which the device is unable to generate and / or release an aerosol. On the other hand, 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 generator becomes operational or non-operating depending on whether the key unit 200 is attached to the main body 2. Thereafter, the key unit 200 acts like a key to prevent unauthorized use and unmanned use of the aerosol generator, particularly by children or infants. The key unit 200 may be a decorative shell or cover, but the decorative aspect of the key unit 200 is subordinate to the safety aspect. In its simplest version, the key unit 200 structures a simple mechanical key that has no electronic components or other active parts and / or no ornaments. In a more advanced version, the key unit 200 may include, for example, an identification item such as an ID tag and / or at least one decorative element which may be customized for a comfortable and recognizable appearance.

[0121] Interaction between main body 2 and key unit 200 To simplify the removable attachment of the key unit 200 to the main body 2, the main body 2 is provided with a keyhole 220, and the key unit 200 is provided with a corresponding key portion 201 that fits into the keyhole 220 when in operation. When inoperable, the keyhole 220 allows fluid communication between the external environment and the aerosol-generating article receiving cavity 29, allowing air to enter or exit the aerosol-generating article receiving cavity 29 through the open keyhole 220.

[0122] The key portion 201 has a substance-containing article receiving cavity 202 configured to receive and hold a substance-containing article 10 in operation, and to release the substance to generate a modified aerosol in operation. When in use, the substance-containing article 10 releases its substance into the aerosol-generating article receiving cavity 29, specifically to its upstream end, or to an aerosol-generating article 8 received therein, or to an aerosol generated by an aerosol generator, or to the airflow used to generate the aerosol.

[0123] The keyhole 220 is provided on a convex surface on the edge of the main body 2 in the central portion of the main body 2 in the height direction H (see Figure 1). The keyhole 220 has a slit-shaped opening. The internal cross-sectional shape of the keyhole 220 is compatible with / complementary to the external cross-sectional shape of the key portion 201 in the direction of insertion of the key portion 201 into the keyhole 220.

[0124] The key portion 201 protrudes perpendicularly from the concave side of the key unit 200. The top and bottom surfaces of the key portion 201 are coated with a layer 204 of elastomer material, such as an FDA-approved silicon-based polymer compound, to ensure airtight sealing of the operating keyhole 220. Using this configuration, the key portion 201 separates the aerosol-generating article receiving cavity 29 from the air intake chamber provided within the main body 2. This structure forces air to flow from the air intake chamber through the air passage 203 provided within the key portion 201 before entering the article receiving cavity 29. An upstream air channel 222 connects the air intake chamber and the keyhole 220 receiving the key element 201 from the external environment. Figures 9 and 10 show this upstream air channel 222 as a dotted line. The upstream air channel 222 forms part of an air intake structure that feeds the aerosol-generating article receiving cavity 29 through an air passage 203 provided within the key portion 201 in the operating state. The air passage 203 opens into the substance-containing article receiving cavity 202 of the key portion 201. As a result, any air passing through the air passage 203 flows through the substance-containing article 10 received in the substance-containing article receiving cavity 202 before entering the aerosol-generating article receiving cavity 29, for example, as a result of the user inhaling the aerosol-generating article 8 received in the aerosol-generating article receiving cavity 29. The diameter of the air passage 203 may be selected in the range of about 0.1 to 2 mm, and the diameter of the air passage 203 is preferably constant over its length. In the operating state, the key portion 201 defines the bottom of the aerosol-generating article receiving cavity 29 and guides / forces the air entering the cavity 29 to flow through the aerosol-generating article 8 received therein.

[0125] As shown in Figure 11(b), the key portion 201 supports the insertion end of the aerosol generating article 8 received in the aerosol generating article receiving cavity 29 when in operation, thereby allowing the heater 28 to heat the aerosol generating substance contained in the aerosol generating article 8 and generate an aerosol. As shown in Figure 11(c), removing the key unit 200 from the main body 2 causes the same aerosol generating article 8 to be improperly positioned in the aerosol generating cavity 29 relative to the heater 28, preventing the aerosol generating substance contained in the aerosol generating article 8 from being heated by the heater 28, so that no aerosol is generated despite heating, or only an insufficient aerosol is generated.

[0126] Thus, the key unit 200 having the key portion 220 is the core functional part for operating the device, specifically the core functional part for the device's air management. As shown in Figures 6 and 8 to 13, the key unit 200 defines an air intake structure that feeds at least a portion of the airflow channel 202 and the aerosol generation cavity 29 when the device is operating.

[0127] Detection unit (for example, embodied as a pressure sensor 221) The device may further include a detection unit for detecting the attachment and removal of the key unit 200 to and from the main body 2. A controller (not shown) may be configured to switch the aerosol generator to an operating state upon detection of the attachment of the key unit 200, and to switch the device to a non-operating state upon detection of the removal of the key unit 200. The detection unit may include a presence or 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 that 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 pogo pin or a push button, for example, as shown in Figures 6 and 8 to 13. The detection unit may also function as an additional tamper-evident safety feature to prevent unauthorized use of the device without the key unit 200 attached to the main body 2.

[0128] Decorative elements of key unit 200 As a customizable item, the key unit 200 includes decorative elements such as a shell or cover that remain visible in operation. As shown in the figure, the decorative elements of the key unit 200, or a portion of the key unit 200 containing the decorative elements, extend substantially perpendicular to the key portion 201 and cover the convex surface of the main body 2 over its entire height H. The decorative elements have a decorative surface on their convex side using decorative printing, texture, or color, such as snakeskin fabric or gray carbon fiber glued, bonded, welded, or soldered thereto. The entire key unit 200, and specifically the decorative elements having a larger extension, may be made of metal and / or plastic.

[0129] To ensure a secure fit onto the main body 2, the key unit 200 may be embodied as an elastically deformable bracket that can be detachably attached to the main body 2 without the use of tools, specifically by a form fit, more precisely by a snap fit. For example, as shown in Figures 7(d), (e), and (f) as well as Figures 5(d) and (e), the key unit 200 accepts two opposing edges of the main body 2 in the longitudinal direction L when in operation. Due to its elastic deformability, the key unit 200, specifically its decorative element, can be stretched for removal from the main body 2 and contracted for attachment to the main body 2 by clip fastening. The curvature and size of the decorative elements of the key unit 200 are matched to the curvature and size of the convex side of the main body 2, so that the concave side of the key unit 200 facing the main body 2 fits snugly into the convex side of the main body 2 in operation and makes complete contact with the main body 2 without any gap between them (see Figures 6a and 7d for details).

[0130] Second key unit As shown in Figure 5, the (same) main body 2 may be combined with a different (second) key unit 200 that is removablely attached to the main body 2 instead of a standard (first) key unit 200, and the key units 200 may differ at least in their decorative elements 230. A sensor may identify which of the different key units 200 is attached to the main body 2, and may cause the controller (ECU) 25 to switch to a specific operating mode upon detection of the attachment and identification of a particular key unit 200.

[0131] A system comprising an apparatus and an aerosol generating article. The system according to the present invention comprises an aerosol generating device according to any one of the prior embodiments, and at least one aerosol generating article 8 configured to be received in an aerosol generating article receiving cavity 29 so as the aerosol generating article 8 is heated by a heater 28 in the operating state, aerosols are generated.

[0132] In the operating state, the static pressure difference (representing the drawdown resistance (RTD)) between the two ends of the aerosol generating article 8 received in the aerosol generating article receiving cavity 29, when measured according to ISO standard 6565:2002, may be approximately 17.5 ml / s ± 50% at the output end when traversed by an airflow of 15 under stable conditions with all ventilation blocked.

[0133] The aerosol generating article 8 of this system is specifically designed and dimensionally configured such that the key portion 201 fits into the aerosol generating article receiving cavity 29 provided within the main body 2, so as to hold the insertion end of the aerosol generating article 8 in an operational state and in the appropriate position, thereby allowing the heater 28 to heat the aerosol generating substance contained in the aerosol generating article 8 and generate an aerosol.

[0134] As a result, the key unit 200 provides another safety function in that its removal from the main body 2 prevents the same aerosol generating article 8 from being improperly positioned within the aerosol generating cavity 29, and prevents the aerosol generating substance contained within the aerosol generating article 8 from being heated by the heater 28. Consequently, no aerosol is generated despite the heating of the aerosol generating article 8 received within the aerosol generating cavity 29 without the key unit 200 being attached to the main body 2. The aerosol generating article 8 may be a nicotine-containing product (NCP) cartridge 9 or a tobacco stick 8.

[0135] A system comprising an apparatus, an aerosol generating article, and an article containing a substance. Another system according to the present invention further comprises an aerosol generator and at least one substance-containing article 10 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 so as to generate a modified aerosol in the operating state.

[0136] The present invention considers and describes a novel consumable 10 having a geometric shape that conforms to a cavity 202 present in the key portion 201 of the key unit 200 in order to hold it. Such a consumable 10 may be made of a porous substrate that incorporates a substance such as a sensory medium to release flavor and aroma. However, the consumable 10 is not limited to containing a flavor substance. Alternatively, the consumable 10 may contain a medicinal ingredient, a plant, CBD, and the like.

[0137] The substance-containing articles 10, also called consumables, can incorporate several types of substances and different properties, as represented by the exemplary consumables 101, 102, and 103. Consumers may purchase such substance-containing articles 10 in stores, each enhancing the sensory aspects of different substances in their individual consumer experience. Such consumables 10 are designed for long-lasting effects and may last for about a week, depending on each consumer's use / consumption of the consumables 10.

[0138] Consumables 10 can be made from several types of porous materials, namely ceramic compounds, as they exist on the market for use in emitting fragrances not only in devices for ambient fragrance emission but also in devices for aromatherapy. Specifically, compounds of materials selected from silicon carbide, silicon-based compounds, cordierite, silica, and zirconium-based ceramic compounds are used for such purposes, and such compounds are known to meet the specifications in applications of aerosolization of inhaled aerosols. These compounds are also known to be suitable from the viewpoint of particle size analysis, such as porous silicon ceramics, which are usually manufactured industrially from silica spinning solutions, and are sintered to obtain a desired range of porosity, where silica particles are introduced by electrospinning and then sintering is applied to obtain the final desired geometric shape and size, as well as the desired porosity. The sintering process usually takes place at a temperature of about 1000°C to 1200°C, and therefore, such materials meet the highest standards in terms of their final use in many applications, including FDA-certified materials for F&B and medical devices. The porosity of such materials is approximately 30-80%, preferably about 40-70%, and most preferably about 50-60%. Furthermore, the porosity of sintered materials can be adjusted by changing the content of introduced silica particles and thus changing the particle size analysis, which allows for good control of the desired porosity at the end from the perspective of the final product. The reference porosity is determined by using a standard method and an equation that gives a decimal value for porosity, knowing the pore volume (Vp) and total volume (Vt) of a defined volume of material. Thus, the porosity (Pt) is given by the ratio of Vp / Vt. To express the porosity as a percentage, simply multiply its decimal by 100%. For example, Pt = 0.51 is therefore 0.51 × 100% = 51%.

[0139] In line with sustainability trends, sustainable consumables 10 can also be designed and manufactured using natural materials, i.e., natural open-cell porous stone materials that are available on the market in granular form, as well as in combination with their silica-based compounds, as both are commonly used for the manufacture of sintered porous products, and can not only meet the required properties in terms of porosity and porosity size as previously identified, but also comply with F&B and FDA requirements for medical devices.

[0140] The geometric and dimensional ratios of consumable 10 are described in the following dimension table, in range and preferred range.

[0141] Table 2: Dimensions of Consumable Item 10 JPEG2026515952000003.jpg39170

[0142] How to operate an aerosol generator A method for operating an aerosol generator according to any of the preceding embodiments further includes the following steps, preferably in the order ABCD or BACD: Step A: The key unit 200 is attached to the main body 2 to switch the device from a non-operational state to an operational state.

[0143] Step B: The aerosol-generating article 8 is received into the aerosol-generating article receiving cavity 29.

[0144] Step C: The actuator is activated to cause the heater 28 to operate, heating the aerosol-generating article 8 received in the aerosol-generating article receiving cavity 29 to generate an aerosol.

[0145] Step D: Remove the key unit 200 from the main body 2 to switch the device from a non-operational state to an operational state.

[0146] Step A may further include inserting the substance-containing article 10 within the key portion 201 of the key unit 200 into the substance-containing article receiving cavity 202 before attaching the key unit 200 to the main body 2.

[0147] Step C may further include using the key portion 201 to hold the substance-containing article 10 and cause it to interact with the aerosol-generating article 8 to generate a modified aerosol.

[0148] Procedure for implementing a preferred embodiment The advantages of the present invention can be summarized as follows:

[0149] In the above-described preferred embodiment of the present invention, the aerosol generator is designed to incorporate a key unit 200 embodied as a removable / replaceable cover / shell. This key unit 200 incorporates a key portion 201 formed as a protruding element which is the core functional part of the device's air management. More specifically, the key portion 201 is the core functional part of the airflow channel and air intake structure that feeds into the aerosolizing chamber, i.e., the aerosol generating article receiving cavity 29, including control of draw-out 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, pharmaceutical, botanical, cannabidiol (CBD), or other substance. In this way, by removing the key unit 200 from the main body 2, the consumer can ensure that the device will not operate or function under any circumstances.

[0150] Dimensions and details Starting from the top, the main body 2 has a rounded shape (approximately 18 mm in diameter) into which an aerosol generating article receiving cavity 29 for an aerosol generating article 8 (tobacco stick) is placed. Two complementary shaped devices that are inserted together into slots will form an elliptical division by an S-curve. Since one of these shapes must adapt to the other when rotated 180 degrees, the presence of a shape at the top must be reflected by its absence at the bottom. What begins as an extruded protrusion will have a slightly flared base, forming a convex curve up to the middle of the product, and the internal shape will form a curve that then slims down and ends at a rounded point.

[0151] Ergonomics The natural shape of the aerosol generator, and specifically the so-called curved teardrop 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, which allows this shape to be held comfortably. This is not the only way to hold it, as the thick end of the device is perfectly shaped to fit into the slot between the consumer's thumb and index finger (between the first toes). This allows for user flexibility, depending on the situation in which the user finds themselves when they want to use the device. Its long, flat base also makes it very stable and much easier to set upright. The consumer does not have to worry about their device falling. Its design also allows the user to set it horizontally without worrying about their device rolling away.

[0152] aesthetics The shape of the aerosol generator, and specifically the shape of the main body 2, utilizes organic curves and somewhat follows the golden ratio, which is found in mathematics and nature and is considered aesthetically pleasing.

[0153] The shape of the main body 2 also makes it appear lighter than it is. By making full use of space, the slimmest parts of the main body 2 give it a smooth, elegant construction and the illusion that it is smaller than it is.

[0154] Childproof The device is configured as a removable / replaceable cover / shell and has a key unit 200 that incorporates a protruding key portion 201, i.e., an element that is the core functional part of the device's air management, including control of the draw-to-drink (RTD). The key portion 201 also includes a cavity 202 for inserting a consumable 10 impregnated with a flavoring substance or made of a porous medium containing medicinal or botanical components such as CBD. In this way, by removing the key unit 200, consumers can ensure that the device does not operate or function under any circumstances.

[0155] As previously referenced, the airflow required to feed the aerosolization is driven by the user's smoke intake and the air intake of the overall airflow within opening 203, which also controls the draw resistance (RTD). In operation, the RTD can be in the range of 10–150 mmWG (millimeters of water column), more preferably 20–140 mmWG, and even more preferably 30–120 mmWG. In non-operational conditions, an additional fluid connection to the external environment is created from the aerosol-generating article receiving cavity by the unoccupied keyhole, and therefore the RTD may decrease to a value of less than 30 mmWG, preferably less than 20 mmWG, and more preferably less than 10 mmWG.

[0156] This aspect of the air passage 203 located within the key portion 201 of the key unit 200, which controls the draw-out resistance (RTD), is an essential functional aspect of this innovation, along with the specific design of the key portion 201, which creates the overall geometric shape and volume measurement of the air management upstream of the aerosolization zone.

[0157] Therefore, regardless of other aspects such as the fact that the key portion 201 also powers on or off via the microswitch 221, when the key unit 200 is removed from the main body 2, it is clear that the device will not only lack the core of the air management function, but also become completely inoperable, even if someone attempts to insert the consumables 8 inside the cavity 29, because the key portion 201 also acts as a stopper and bottom for the cavity 29, so such consumables 8 will always be misplaced inside the cavity 29.

[0158] Release of substances (e.g., flavor and aroma) An overall embodiment of the device having a removable key unit 200 incorporates the characteristic of substance release during the consumption of aerosol-generating articles 8 such as main consumables and HTP sticks, while retaining the release of substances such as aromas / fragrances when the device is not in operation. These characteristics are obtained by a specific design of the main body 2 of the device and a special key unit 200 when using specific consumables 10 for the substance release of flavors, aromas and fragrances, medicinal or plant substances, CBD, and the like.

[0159] Possibility of accessories As shown in Figures 16 and 17, the ecosystem may include not only the NCP device and the device as a geometrically combined power charger 6, but also a Bluetooth loudspeaker unit 5 and a wireless charger unit 4.

[0160] The device will have the potential for customization using a key unit 200 embodied as a removable or replaceable cover or shell. The shell may be a magnetic curve that can be inserted into a slot on the convex outer curve of the main body 2, and it may have any number of textures or colors to which it can be attached (e.g., snakeskin fabric, gray carbon fiber). This will allow the user to match their device to their clothing or event, and will also open up the possibility of "special edition" key units 200 for data transfer or collection.

[0161] Desired features The special shape of the device provides sufficient volumetric space to incorporate all the desired functions for operating the device with the following performance characteristics:

[0162] The key unit 200, which can be selected by the consumer to cover aesthetics, may be a removable or replaceable cover or shell that enables childproof functionality when removed, based on a specific key part 201 that not only structures the core of the air management and aerosolization chamber (aerosol-generating article receiving cavity 29) of the device but also controls the device's draw resistance (RTD). Thus, the consumer only needs to remove such key unit 200, and the device is completely disabled for any use in terms of power, mechanical and air management functions.

[0163] o A cavity 202 within the key portion 201 of the key unit 200, which allows the use of the consumable 10 for the purpose of releasing substances such as flavors, aromas or fragrances, medicinal or botanical substances, CBD, and the like into the air intake, thereby enhancing the sensory experience during the consumption of the main HTP / HNB consumable for nicotine delivery.

[0164] The presence of the consumables 10 in the cavity 202 of the key portion 201 of the key unit 200 creates conditions for retaining the release of substances such as fragrances / scents when the device is not in operation, and in this way maintains conditions for storing and handling the device in a comfortable and pleasant manner at all times.

[0165] The core of innovation: The aerosol generator incorporates a cover / shell that can be assembled and disassembled by the consumer, and has protruding elements that mechanically and functionally engage with the main body of the device and the core of its aerosolizing engine. In this manner, once the cover / shell is removed, the device is completely disabled.

[0166] The aerosol generator described above incorporates cavities within its protruding elements for inserting and holding consumables. These protruding elements engage mechanically and functionally with the main body of the device. These consumables release flavor during the aerosolization and normal operation of the device, enhancing the consumer experience.

[0167] The aerosol generator described above retains the fragrance of consumables when the device is not operating for aerosolization, and these consumables retain the release of fragrance / scent through natural volatilization.

[0168] Applications of the present invention outside the tobacco industry: Outside the tobacco industry, the present invention can be applied to aerosol generators used in the life sciences or pharmaceutical industries.
