Description

Technical Field

[0001] This invention relates to an aerosol generating apparatus. Background Technology

[0002] Aerosol generation is known. One type of aerosol generation system is the electronic cigarette. Electronic cigarettes typically use a liquid aerosol-forming matrix that is evaporated to form an aerosol. Heated-to-burn (HNB) devices heat one or more solid aerosol-forming matrices to a temperature that causes one or more components of the aerosol-forming matrix to evaporate without burning the solid aerosol-forming matrix. Additionally, hybrid aerosol-generating devices that combine liquid aerosol-forming and HNB functions are known. All three types of these devices—liquid aerosol-forming devices or electronic cigarettes, HNB devices, and hybrid devices—are aerosol-generating devices.

[0003] Typically, an aerosol generation apparatus includes a top section and a body. The body typically contains a power source. An alternative top section typically includes a heater and means for introducing the aerosol-forming matrix into the heater.

[0004] The aerosol-forming matrix can be disposed in or inserted into a cavity (such as a heating chamber) in the top portion of the aerosol-generating apparatus. Heating elements can be arranged in or around the heating chamber to heat the aerosol-forming matrix after the aerosol-generating article is provided in the heating chamber of the aerosol-generating apparatus. Summary of the Invention

[0005] An aerosol generating apparatus is desired to have the ability to modify the aroma of the generated aerosols. An aerosol generating apparatus is desired to have the aroma modification of the generated aerosols that can be controlled and modified by the user. An aerosol generating apparatus is desired to have user-based aroma modification of the generated aerosols, which is a simple aerosol generating apparatus. An aerosol generating apparatus is desired to have aroma modification capabilities. An aerosol generating apparatus is desired to have the aroma modified by providing a fragrance cartridge separate from the solid or liquid aerosol generating materials.

[0006] According to embodiments of the present invention, a replaceable fragrance cartridge for an aerosol generating apparatus is provided. The cartridge can be inserted into the aerosol generating apparatus such that an airflow passes through the fragrance cartridge before or after the airflow passes through the aerosol generating section of the aerosol generator. The fragrance cartridge can provide fragrance upstream or downstream of the aerosol generator.

[0007] In one embodiment, the cartridge includes a shell and a flavoring matrix. The flavoring matrix is ​​disposed within the shell. The flavoring matrix may be tobacco-free. The flavoring matrix may be nicotine-free. Preferably, the flavoring matrix includes a flavoring agent.

[0008] The housing includes a proximal orifice in its proximal portion. Preferably, the proximal orifice is located in the proximal end face of the housing. The proximal end face is located in the proximal portion. The housing also includes a distal orifice in its distal portion. Preferably, the distal orifice is located in the distal end face of the housing. The distal end face is located in the distal portion. The fragrance matrix includes a matrix orifice. The proximal orifice, distal orifice, and matrix orifice are aligned with each other to form a channel for airflow through the fragrance cartridge.

[0009] The fragrance of the generated aerosol can be modified by providing replaceable fragrance cartridges. Because the cartridges are replaceable, users can adjust the fragrance of the generated aerosol as needed.

[0010] The container can be a non-heated container. The flavoring agent from the spice matrix can be entrained in the air flowing through the container's airflow channels. Preferably, the spice matrix is ​​in direct contact with the air flowing through the container's airflow channels. Direct contact between the spice matrix and the container's airflow channels promotes the entrainment of the flavoring agent in the air flowing through the container's airflow channels.

[0011] The airflow channel in the cylinder can be straight. The airflow channel can extend directly from the distal orifice through the matrix orifice to the proximal orifice. The distal orifice of the shell can directly abut the matrix orifice of the matrix portion. The matrix orifice of the matrix portion can directly abut the proximal orifice of the shell. The distal end face of the shell can directly abut the fragrance matrix. The fragrance matrix can directly abut the proximal end face of the shell. The fragrance matrix can be sandwiched between the proximal end face and the distal end face of the shell. The airflow channel in the cylinder can be formed by the distal orifice, the matrix orifice, and the proximal orifice. Preferably, the airflow channel extends parallel to the central axis.

[0012] The cartridge may contain only the spice matrix. The spice matrix may be surrounded by the shell of the cartridge. The proximal end face of the spice matrix may be covered by the proximal end face of the shell. The distal end face of the spice matrix may be covered by the distal end face of the shell. The sides of the spice matrix may be covered by the sidewalls of the shell.

[0013] The tube may be disc-shaped. The proximal end face of the tube may be flat. The distal end face of the tube may be flat. The sidewalls of the tube may be tubular. Preferably, the tube is cylindrical. For example, the cross-section of the spice tube may be approximately circular, elliptical, square, or rectangular.

[0014] The cartridge may include a removable, fluid-impermeable proximal foil covering the proximal orifice. The removable, fluid-impermeable proximal foil can be peeled off by the user before using the cartridge. The foil can also be peeled off by the user before inserting the cartridge into the aerosol generating device.

[0015] The cartridge may include a removable, fluid-impermeable distal foil covering the distal orifice. The removable, fluid-impermeable distal foil can be peeled off by the user before using the cartridge. The foil can also be peeled off by the user before inserting the cartridge into the aerosol generating device.

[0016] The shell can be porous. By providing a porous shell, flavoring agents from the spice matrix can be immersed in the shell. The flavoring agents from the spice matrix can be wicked by the porous shell. The contact surface between the flavoring agents and the air flowing through the cylinder airflow channel can be increased by the porous shell. In particular, the flavoring agents from the spice matrix can be wicked by one or both of the proximal and distal orifices of the shell facing the cylinder airflow channel. The entire shell can be porous. Alternatively, a portion of the shell can be porous. Advantageously, the portion of the shell forming one or both of the proximal and distal orifices can be porous.

[0017] The housing of the spice cartridge can be a single, integral element. However, preferably, the housing of the spice cartridge consists of at least two elements. The proximal portion of the spice cartridge may include a proximal orifice and a proximal end face of the housing. The distal portion of the spice cartridge may include a distal orifice and a distal end face. The sidewall of the spice cartridge may be one or more of the following: a portion of the proximal portion of the spice cartridge, a portion of the distal portion of the spice cartridge, and a separate element. The proximal portion may be attached to the distal portion. The spice matrix may be sandwiched between the proximal and distal portions. The proximal portion may be removably attached to the distal portion. The spice matrix may be recovered after use by separating the proximal and distal portions.

[0018] The proximal portion of the spice cartridge may be configured to be removably attached to one of the sidewall and the distal portion of the spice cartridge. The distal portion of the spice cartridge may be configured to be removably attached to one of the sidewall and the proximal portion of the spice cartridge. For example, the proximal portion of the spice cartridge may include a male connector, and the distal portion of the spice cartridge may include a female connector, and vice versa. The sidewall may include corresponding male and female connectors to be attached between the proximal and distal portions. Alternatively, the proximal portion of the spice cartridge may be directly and removably attached to the distal portion of the spice cartridge. Removable attachment may be facilitated by a threaded connection. Removable attachment may be facilitated by a snap-fit ​​connection. Removable attachment may be facilitated by a friction-fit connection.

[0019] The proximal and distal portions of the housing can be connected using a Luer connector. One or more of the proximal orifice, distal orifice, and matrix orifice can be configured as a Luer connector. One or both of the proximal and distal portions of the spice cartridge housing can include a Luer connector. By providing one or more of these components as Luer connectors, reliable attachment between one or more of the proximal orifice, distal orifice, and matrix orifice can be achieved.

[0020] In an additional embodiment, one or more of the proximal orifice, distal orifice, and matrix orifice may include a connector. The connector may be configured to connect one or more of the proximal orifice, distal orifice, and matrix orifice. Preferably, the connector is configured to securely hold the components of the fragrance cartridge together by allowing removable attachment between the components. Preferably, the connector allows removable attachment between the proximal portion and the distal portion of the fragrance cartridge. The connector may be any connector known in the art that produces a releasable hermetic and / or liquid-tight seal. For example, the connector may be a threaded connection or a snap-fit ​​connection.

[0021] The fragrance matrix may include one or more of the following: fragrance liquid, a high-retention material impregnated with fragrance liquid, fragrance gel, particles impregnated with fragrance liquid, and gel capsules comprising fragrance liquid or fragrance gel. If the fragrance matrix includes a fragrance gel, the fragrance gel may be configured as a viscous fragrance gel. If the fragrance matrix includes particles or gel capsules, the particles or gel capsules may be embedded in a carrier. Preferably, the fragrance matrix is ​​configured to be dimensionally stable, such that matrix pores can be located within the fragrance matrix.

[0022] Specifically, by providing the fragrance matrix as a highly retaining material impregnated with fragrance liquid, the fragrance liquid can be wicked by the highly retaining material. During use, the fragrance liquid can be entrained in the air flowing through the airflow channels of the cylinder. Therefore, a portion of the fragrance matrix adjacent to the airflow channels of the cylinder can be depleted. Fragrance liquid from other non-depleted portions of the fragrance matrix can be wicked towards portions of the fragrance matrix adjacent to the airflow channels of the cylinder, so that fragrance liquid from other portions of the fragrance matrix is ​​gradually entrained in the air flowing through the airflow channels of the cylinder.

[0023] The fragrance matrix may include an ambient temperature atomizable fragrance matrix. The ambient temperature atomizable fragrance matrix can become air-propagable under standard pressure and temperature conditions. Therefore, the ambient temperature atomizable fragrance matrix can be atomized at the contact surface between the fragrance matrix and the air flowing through the cylinder's airflow channel. The atomized ambient temperature atomizable fragrance matrix can be entrained by the air flowing through the cylinder's airflow channel. Because the fragrance matrix is ​​ambient temperature atomizable, a heated cylinder is not required to atomize the fragrance matrix. Therefore, the cylinder is preferably constructed as a non-heated cylinder.

[0024] The fragrance matrix may include at least one aerosol forming agent. An aerosol forming agent is any suitable known compound or mixture of compounds that, in use, facilitates the formation of a dense and stable aerosol and is substantially resistant to thermal degradation at the system's operating temperature. Suitable aerosol forming agents are well known in the art and include, but are not limited to: polyols, such as triethylene glycol, 1,3-butanediol, and glycerol; esters of polyols, such as mono, di, or triacetic acid esters of glycerol; and fatty acid esters of mono, di, or polycarboxylic acids, such as dimethyl dodecanoate and dimethyl tetradecanoate. The aerosol forming agent may be a polyol or a mixture thereof, for example, triethylene glycol, 1,3-butanediol, and glycerol. The aerosol forming agent may be propylene glycol. The aerosol forming agent may include both glycerol and propylene glycol.

[0025] In this embodiment, the flavor matrix is ​​a high-retention material that may be shaped to provide matrix pores. For example, the flavor matrix may be a material that is wetted, soaked, or impregnated with a liquid or gel as a flavoring agent. The flavoring agent may include water, solvents, ethanol, plant extracts, and natural or artificial flavorings. The liquid may include nicotine. The liquid may have a nicotine concentration between about 0.5% and about 10%, for example, about 2%.

[0026] The shell of the spice cartridge can be a rigid shell. As used herein, the term "rigid shell" refers to a self-supporting shell. A rigid shell of the spice cartridge can provide mechanical support for the spice cartridge. The shell of the spice cartridge can include any suitable material. The shell of the spice cartridge can include a material that is substantially fluid-impermeable. The shell of the spice cartridge can include transparent or translucent portions, allowing the matrix portion stored within the spice cartridge to be visible to the user through the shell. The spice cartridge can be configured to protect the aerosol-forming matrix stored within the spice cartridge from light. This reduces the risk of matrix degradation and maintains a high level of hygiene.

[0027] The fragrance cartridge may include one or more inlets, which may be one-way inlets. This allows ambient air to enter the fragrance cartridge. The one or more one-way inlets may be a semi-permeable membrane or a one-way valve, which is permeable to allow ambient air to enter the fragrance cartridge and impermeable to substantially prevent air and liquid from leaving the inside of the fragrance cartridge. The one or more semi-open inlets may allow air to enter the fragrance cartridge under certain conditions. The fragrance cartridge may be refillable. Alternatively, the fragrance cartridge may be configured as a replaceable fragrance cartridge. The fragrance cartridge may be part of a replaceable cartridge or configured as a replaceable cartridge.

[0028] The term "ambient air" refers to the air drawn into the aerosol generating device from outside the device. In other words, the term "air" refers to the air surrounding the aerosol generating device.

[0029] The present invention further relates to an aerosol generating apparatus comprising a top portion, a replaceable fragrance cartridge as described herein, and a body. The cartridge may be configured to be removably attached between the top portion and the body.

[0030] Users can easily modify the aroma of the aerosol generated by the aerosol generator by inserting a desired aroma cartridge containing the desired fragrance into the aerosol generator. Since the aroma cartridge is replaceable, users can modify the aroma of the generated aerosol by changing the aroma cartridge to a different desired fragrance.

[0031] The spice cartridges can be modular. Various different spice cartridges can be used in conjunction with a single aerosol generating device.

[0032] The top portion of the aerosol generating device can be configured as an inlet portion. The top portion can be configured as a mouthpiece. Alternatively, the top portion can have a cavity for inserting a solid aerosol generating matrix. In conventional aerosol generating devices, an air inlet, an airflow channel, and an air outlet are provided. In this invention, preferably, the fragrance cartridge is disposed in a common airflow channel, so that the aerosol generating device does not require an additional air inlet or airflow channel. In other words, the fragrance cartridge can be modularly sandwiched between the top portion and the body, using the same common airflow channel. In embodiments, the fragrance cartridge can be refillable.

[0033] The airflow path allows the user to draw air through a heated substrate. The top portion may include a top portion airflow channel. The body may include a body airflow channel. The body airflow channel, the cylinder airflow channel, and the top portion airflow channel may be fluidly connected to form a common airflow channel for the aerosol generating device.

[0034] Preferably, the aerosol generating device can be used without a cartridge. In this case, the top portion is attached to the main body such that the airflow channel of the top portion is in fluid communication with the airflow channel of the main portion. These two airflow channels form a common airflow channel. If the user wishes to modify the fragrance of the generated aerosol, the user can insert a fragrance cartridge, as described herein, between the top portion and the main body to modify the desired fragrance. This insertion of the fragrance cartridge utilizes the same top portion airflow channel and main portion airflow channel by aligning the cartridge airflow channel with both airflow channels. Therefore, the resulting common airflow channel is a combination of the previous airflow channel (in the case of an aerosol generating device without a fragrance cartridge) and the cartridge airflow channel of the fragrance cartridge.

[0035] The top portion may include a cavity configured to receive an aerosol-generating article comprising an aerosol-forming matrix. The top portion may include a heating element disposed within or around the cavity. The heating element may be configured to heat the aerosol-forming matrix of the aerosol-generating article.

[0036] The heating element can be arranged spaced apart from the replaceable fragrance cartridge, such that the fragrance matrix is ​​substantially thermally insulated from the heating element. The heating element can be configured to heat the aerosol-forming matrix of the aerosol-generating article. Simultaneously, the heating element can be configured not to heat the fragrance cartridge. As described herein, the fragrance cartridge can be a non-heated fragrance cartridge. Therefore, the aerosol generating apparatus does not require additional heating elements to modify the aroma of the aerosol. In an alternative embodiment, the heating element is configured to also heat the fragrance cartridge, or the aerosol generating apparatus may include other heating elements for heating the fragrance cartridge when it is received by the aerosol generating apparatus.

[0037] The replaceable fragrance cartridge can be configured to attach between the top portion and the body. Preferably, the attachment is removable. The top portion of the aerosol generating device can be configured to removably attach to the proximal portion of the fragrance cartridge. The main portion of the aerosol generating device can be configured to removably attach to the distal portion of the fragrance cartridge. The removable attachment between the aerosol generating device and the fragrance cartridge can be facilitated by any known attachment means. For example, the top portion of the aerosol generating device may include a male connector element, and the proximal portion of the fragrance cartridge may include a female connector element, and vice versa. The main portion of the aerosol generating device may include a male connector element, and the distal portion of the fragrance cartridge may include a female connector element, and vice versa. The removable attachment between one or both of the top portion and the body of the aerosol generating device and one or both of the proximal and distal portions of the fragrance cartridge can be configured as a threaded connection, a snap-fit ​​connection, or a friction-fit connection.

[0038] The replaceable spice cartridge can be configured to be attached between the top portion and the body by placing the cartridge between the top portion and the body and by rotating the cartridge. Attachment of the replaceable spice cartridge between the top portion and the body can be facilitated by a swivel connection, a bayonet mount, a Luer connection, or any other quick-reversible connection known in the art.

[0039] The removable attachment of the fragrance cartridge to the aerosol generator depends on the chosen connection. If the connection is facilitated by a threaded connection, the user can screw the proximal portion of the fragrance cartridge onto the top portion of the aerosol generator. Alternatively, the user can screw the top portion of the aerosol generator onto the proximal portion of the fragrance cartridge. Subsequently, the user can screw the distal portion of the fragrance cartridge onto the body of the aerosol generator. Alternatively, the user can then screw the body of the aerosol generator to move the distal portion of the fragrance cartridge. As another alternative, the user can initially screw the distal portion of the fragrance cartridge onto the body of the aerosol generator and then subsequently screw the fragrance cartridge onto the top portion of the aerosol generator.

[0040] If the connection is facilitated as a snap-fit ​​or friction-fit connection, the user can initially press the proximal portion of the fragrance cartridge against the top portion of the aerosol generating device to establish a snap-fit ​​or friction-fit connection between the proximal and top portions. Subsequently, the user can press the distal portion of the fragrance cartridge against the body of the aerosol generating device to establish a snap-fit ​​or friction-fit connection between the distal portion and the body. Alternatively, the user can first press the distal portion of the fragrance cartridge against the body, and then subsequently press the proximal portion against the top portion.

[0041] If the connection is facilitated as a swivel connection or a bayonet mount, the user can place the fragrance cartridge between the top portion of the aerosol generating device and the body of the aerosol generating device. Optionally, the protrusion of the fragrance cartridge can be placed in a recess of the aerosol generating device, or in a recess of the fragrance cartridge insertion portion of the aerosol generating device, to facilitate proper alignment of the fragrance cartridge between the top portion and the body. Subsequently, the user can rotate the fragrance cartridge relative to the aerosol generating device to facilitate engagement of the swivel connection or bayonet mount of the fragrance cartridge with the corresponding element of the aerosol generating device.

[0042] The fragrance cartridge can be securely held between the top portion of the aerosol generating device and the main body via any of the aforementioned connecting devices. Furthermore, if the fragrance cartridge is depleted, any of the aforementioned connecting devices allows for the separation of the fragrance cartridge from the aerosol generating device. A fresh fragrance cartridge can then be removably attached to the aerosol generating device. Alternatively or additionally, in order to replace the depleted fragrance cartridge with a fresh one, the fragrance matrix of the depleted fragrance cartridge can be refilled.

[0043] To refill a depleted fragrance cartridge, the fragrance cartridge may include a refill orifice. The refill orifice may be configured as a membrane or a one-way valve. In an embodiment, the refill orifice may be arranged within the housing of the fragrance cartridge so that it is accessible when the fragrance cartridge is rotated relative to other components of the aerosol generating apparatus. This embodiment is particularly advantageous if a swivel connection or bayonet mount facilitates the connection between the fragrance cartridge and the aerosol generating apparatus. Preferably, when the fragrance cartridge in this embodiment is rotated to the operating position, the refill orifice is inaccessible to prevent spillage of the fragrance matrix.

[0044] As used herein, the term "aerosol generating device" refers to an apparatus that interacts with an aerosol-forming matrix to generate an aerosol. The aerosol-forming matrix may be part of an aerosol-generating article, such as a smoking article. An aerosol generating device may be a smoking device that interacts with the aerosol-forming matrix of an aerosol-generating article to generate an aerosol that can be directly inhaled into the user's lungs through the user's mouth. An aerosol generating device may be a retainer. The apparatus may be an electrically heated smoking device. An aerosol generating device may include a housing, circuitry, a power supply, a heating chamber, and a heating element.

[0045] An aerosol generating apparatus may include a cavity for receiving an aerosol-generating article comprising an aerosol-forming matrix. The cavity of the aerosol generating apparatus may have an open end into which the aerosol-generating article is inserted. The open end may be a proximal end. The cavity may have a closed end opposite the open end. The closed end may be the bottom of the cavity. The closed end may be closed except for providing an air gap disposed in the base. The base of the cavity may be flat. The bottom of the cavity may be circular. The bottom of the cavity may be disposed upstream of the cavity. The open end may be disposed downstream of the cavity. The cavity may have an elongated extension. The cavity may have a longitudinal central axis. The longitudinal direction may be a direction extending along the longitudinal central axis between the open end and the closed end. The longitudinal central axis of the cavity may be parallel to the longitudinal axis of the aerosol generating apparatus.

[0046] The cavity can be configured as a heating chamber. The cavity can have a cylindrical shape. The cavity can have a hollow cylindrical shape. The shape of the cavity can correspond to the shape of the aerosol-generating article to be received within it. The cavity can have a circular cross-section. The cavity can have an elliptical or rectangular cross-section. The cavity can have an inner diameter corresponding to the outer diameter of the aerosol-generating article.

[0047] The airflow channel at the top can extend through the cavity. Ambient air can be drawn into the aerosol generating device, enter the cavity, and flow to the user through the airflow channel at the top. Downstream of the cavity, a mouthpiece can be installed, or the user can inhale directly from the aerosol-generating product. The airflow channel can extend through the mouthpiece. Upstream of the cavity, a flavoring cartridge can be installed.

[0048] As used herein, the terms “upstream,” “downstream,” “proximal,” and “far” are used to describe the relative position of a component or part of a component of an aerosol generating device with respect to the direction in which it is drawn by a user during use of the aerosol generating device.

[0049] The aerosol generating apparatus may include a heating element. The heating element may include a resistive material. Suitable resistive materials include, but are not limited to: semiconductors, such as doped ceramics, “conductive” ceramics (e.g., molybdenum disilicide), carbon, graphite, metals, metal alloys, and composite materials made of ceramic and metallic materials. Such composite materials may include doped or undoped ceramics. Examples of suitable doped ceramics include doped silicon carbide. Examples of suitable metals include titanium, zirconium, tantalum, platinum, gold, and silver. Examples of suitable metal alloys include those containing stainless steel, nickel, cobalt, chromium, aluminum, titanium, zirconium, hafnium, niobium, molybdenum, tantalum, tungsten, tin, gallium, manganese, gold, iron, and those containing nickel, iron, cobalt, stainless steel, etc. And superalloys mainly composed of iron-manganese-aluminum alloys. In composite materials, resistive materials can be optionally embedded in insulating materials, encapsulated by insulating materials, coated by insulating materials, or vice versa, depending on the energy transfer kinetics and desired external physicochemical properties.

[0050] Aerosol generating apparatus may include an internal heating element, an external heating element, or both, wherein “internal” and “external” refer to the aerosol forming matrix. The internal heating element may take any suitable form. For example, it may take the form of a heating blade. Alternatively, the internal heater may take the form of a sleeve or substrate with different conductive portions, or a resistance metal tube. Alternatively, the internal heating element may be one or more heating needles or rods penetrating the center of the aerosol forming matrix. Other alternatives include heating wires or filaments, such as Ni-Cr (nickel-chromium), platinum, tungsten, or alloy wires, or heating plates. Optionally, the internal heating element may be deposited within or on a rigid carrier material. In one such embodiment, the resistance heating element may be formed using a metal having a defined relationship between temperature and resistivity. In such exemplary apparatuses, the metal may be formed as a trace on a suitable insulating material (e.g., ceramic material) and then sandwiched within another insulating material (e.g., glass). A heater formed in this manner can be used to heat and monitor the temperature of the heating element during operation.

[0051] The external heating element can take any suitable form. For example, it can take the form of one or more flexible heating foils on a dielectric substrate (e.g., polyimide). The flexible heating foil can be shaped to conform to the periphery of the cavity. Alternatively, the external heating element can take the form of a metal mesh, flexible printed circuit board, molded interconnect device (MID), ceramic heater, flexible carbon fiber heater, or can be formed on a suitable shaped substrate using coating techniques (e.g., plasma vapor deposition). The external heating element can also be formed using a metal with a defined relationship between temperature and resistivity. In such exemplary devices, the metal can be formed as traces between two layers of suitable insulating material. External heating elements formed in this way can be used to heat and monitor the temperature of the external heating element during operation.

[0052] Internal or external heating elements may include radiators or heat storage units comprising materials capable of absorbing and storing heat and then releasing it to the aerosol-forming matrix over time. The heat sink may be formed from any suitable material, such as a suitable metallic or ceramic material. In one embodiment, the material has a high heat capacity (sensible heat storage material), or the material is capable of absorbing heat and then releasing it via a reversible process (e.g., a high-temperature phase change). Suitable sensible heat storage materials include silica gel, alumina, carbon, glass pads, glass fibers, minerals, metals or alloys such as aluminum, silver, or lead, and cellulose materials such as paper. Other suitable materials for releasing heat via a reversible phase change include paraffin wax, sodium acetate, thiamethoxam, wax, polyethylene oxide, metals, metal salts, mixtures of good salts, or alloys. The radiator or heat storage unit may be arranged such that it is in direct contact with the aerosol-forming matrix and can directly transfer the stored heat to the matrix. Furthermore, the heat stored in the radiator or heat storage unit may be transferred to the aerosol-forming matrix via a heat conductor (e.g., a metal tube).

[0053] The heating element advantageously heats the aerosol-forming matrix through conduction. The heating element may at least partially contact the matrix or a carrier on which the matrix is ​​deposited. Alternatively, heat from an internal or external heating element may be conducted to the matrix via a thermally conductive element.

[0054] During operation, the aerosol-forming matrix can be completely contained within the aerosol-generating device. In this case, the user can inhale through the mouthpiece of the aerosol-generating device. Alternatively, during operation, a smoking product containing the aerosol-forming matrix can be partially contained within the aerosol-generating device. In this case, the user can directly inhale through the smoking product.

[0055] As an alternative to resistance heating elements, heating elements can be constructed as induction heating elements. Induction heating elements may include induction coils and inductors. Generally, an inductor is a material capable of absorbing electromagnetic energy and converting it into heat. When placed in an alternating electromagnetic field, eddy currents are typically induced and hysteresis losses occur in the inductor, thereby causing the inductor to heat up. Changing the electromagnetic field generated by one or more induction coils heats the inductor, which then transfers the heat to the aerosol-generating article, thus forming an aerosol. Heat transfer can be primarily through thermal conduction. This type of heat transfer is optimal if the inductor is in close thermal contact with the aerosol-generating matrix.

[0056] The sensor can be formed of any material capable of being inductively heated to a temperature sufficient to generate aerosols from the aerosol-forming matrix. Preferred sensors may comprise or be composed of ferromagnetic materials, such as ferromagnetic alloys, ferritic iron, or ferromagnetic steel or stainless steel. Suitable sensors may be aluminum or include aluminum. Preferred sensors can be heated to temperatures exceeding 250 degrees Celsius.

[0057] Preferred receptors are metallic receptors, such as stainless steel. However, receptor materials may also include or be made from a variety of the following: graphite; molybdenum; silicon carbide; aluminum; niobium; Inconel alloy (an austenitic nickel-chromium superalloy); metallized films; ceramics such as zirconium oxide; transition metals such as iron, cobalt, and nickel; or metalloid components such as boron, carbon, silicon, phosphorus, and aluminum.

[0058] Preferably, the receptor material is a metallic receptor material. The receptor can also be a multi-material receptor and may include a first receptor material and a second receptor material. In some embodiments, the first receptor material may be configured to be in close physical contact with the second receptor material. The Curie temperature of the second receptor material is preferably below the ignition point of the aerosol-forming matrix. The first receptor material is preferably primarily used to heat the receptor when it is placed in a fluctuating electromagnetic field. Any suitable material can be used. For example, the first receptor material may be aluminum, or it may be an iron-containing material such as stainless steel. The second receptor material is preferably primarily used to indicate when the receptor has reached a specific temperature, which is the Curie temperature of the second receptor material. The Curie temperature of the second receptor material can be used to regulate the temperature of the entire receptor during operation. Suitable materials for the second receptor material may include nickel and certain nickel alloys.

[0059] By providing a sensor having at least a first sensor material and a second sensor material, the heating of the aerosol forming matrix and the temperature control of the heating can be separated. Preferably, the second sensor material is a magnetic material having a second Curie temperature that is substantially the same as the desired maximum heating temperature. That is, preferably, the second Curie temperature is approximately the same as the temperature to which the sensor should be heated in order to generate an aerosol from the aerosol forming matrix.

[0060] When an induction heating element is used, it can be configured as an internal heating element as described herein or as an external heater as described herein. If the induction heating element is configured as an internal heating element, the sensor element is preferably configured as a pin or blade for penetrating the aerosol-generating article. If the induction heating element is configured as an external heating element, the sensor element is preferably configured as a cylindrical sensor that at least partially surrounds the cavity or forms the sidewall of the cavity.

[0061] An aerosol generating device may include circuitry. The circuitry may include a microprocessor, which may be a programmable microprocessor. The microprocessor may be part of a controller. The circuitry may include additional electronic components. The circuitry may be configured to regulate the power supply to a heating element. Power may be continuously supplied to the heating element after the aerosol generating device is activated, or it may be supplied intermittently, such as on a puff-by-puff basis. Power may be supplied to the heating element in the form of current pulses. The circuitry may be configured to monitor the resistance of the heating element and preferably control the power supply to the heating element based on the resistance of the heating element.

[0062] The aerosol generating device may include a power source, typically a battery, within the main body of the device. In one embodiment, the power source is a lithium-ion battery. Alternatively, the power source may be a nickel-metal hydride battery, a nickel-cadmium battery, or a lithium-based battery such as a lithium-cobalt, lithium-iron-phosphate, lithium titanate, or lithium-polymer battery. Alternatively, the power source may be another form of charge storage device, such as a capacitor. The power source may require charging and may have a capacity capable of storing sufficient energy for one or more uses; for example, the power source may have sufficient capacity to continuously generate aerosols for approximately six minutes or multiples of six minutes. In another instance, the power source may have sufficient capacity to provide a predetermined number of suction cycles or intermittent activation of the heater.

[0063] As used herein, the term "aerosol-generating article" refers to an article comprising an aerosol-forming matrix capable of releasing volatile compounds that can form aerosols. For example, an aerosol-generating article can be a smoking article that generates aerosols that can be directly inhaled into a user's lungs through their mouth. Aerosol-generating articles can be disposable. As described herein, aerosol-generating articles can be provided in addition to fragrance cartridges. When the aerosol-generating article is preferably received by a cavity in the top portion of an aerosol-generating device, the fragrance cartridge is preferably disposed upstream of the cavity between the top portion of the aerosol-generating device and the body.

[0064] Aerosol-generating articles can be substantially cylindrical in shape. Aerosol-generating articles can be substantially elongated. Aerosol-generating articles can have a length and a circumference substantially perpendicular to said length. Aerosol-generating articles can be substantially rod-shaped. Aerosol-forming matrices can be substantially cylindrical in shape. Aerosol-forming matrices can be substantially elongated. Aerosol-forming matrices can also have a length and a circumference substantially perpendicular to said length. Aerosol-forming matrices can be substantially rod-shaped.

[0065] The aerosol-generating matrix may include an aerosol forming agent. Preferably, the aerosol-generating matrix comprises: homogenized tobacco material, an aerosol forming agent, and water. Providing homogenized tobacco material can improve aerosol generation, nicotine content, and aroma characteristics of aerosols generated during the heating of aerosol-generating articles. Specifically, the process of manufacturing homogenized tobacco involves grinding tobacco leaves, which more effectively releases nicotine and aroma upon heating.

[0066] The homogeneous tobacco material is preferably provided in sheet form, which is folded, rolled, or cut into strips. In a particularly preferred embodiment, the sheet is cut into strips with a width between about 0.2 mm and about 2 mm, more preferably between about 0.4 mm and about 1.2 mm. In one embodiment, the strip width is about 0.9 mm.

[0067] Alternatively, the homogeneous tobacco material can be formed into spheres by rolling. The average diameter of the spheres is preferably between about 0.5 mm and about 4 mm, more preferably between about 0.8 mm and about 3 mm.

[0068] The aerosol generating matrix preferably comprises: homogeneous tobacco material, by weight, between about 55% and about 75%; an aerosol forming agent, by weight, between about 15% and about 25%; and water, by weight, between about 10% and about 20%.

[0069] Before measuring the aerosol-generating matrix samples, they were equilibrated at 22°C and 50% relative humidity for 48 hours. The moisture content of the homogenized tobacco material was determined using the Karl Fischer technique.

[0070] Sheets of homogeneous tobacco material for use in aerosol-generating articles including capsules can be formed by agglomerating granular tobacco, which is obtained by grinding or otherwise pulverizing one or more of tobacco leaves and tobacco stems.

[0071] Sheets of homogeneous tobacco material supplied for use in aerosol-generating articles including capsules may include one or more inherent binders as endogenous tobacco binders, one or more exogenous binders as exogenous tobacco binders, or combinations thereof, to facilitate the agglomeration of particulate tobacco. Alternatively or additionally, sheets of homogeneous tobacco material may include other additives, including but not limited to tobacco and non-tobacco fibers, flavorings, fillers, aqueous and non-aqueous solvents, and combinations thereof.

[0072] Suitable external binders for use in sheets of homogeneous tobacco material supplied for use in aerosol-generating articles comprising capsules are known in the art and include, but are not limited to: gums, such as guar gum, xanthan gum, gum arabic, and locust bean gum; cellulose binders, such as hydroxypropyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, methyl cellulose, and ethyl cellulose; polysaccharides, such as starch; organic acids, such as alginic acid; conjugate base salts of organic acids, such as sodium alginate, agar, and 30 pectin; and combinations thereof.

[0073] Various reconstitution processes for producing sheets of homogeneous tobacco material are known in the art. These processes include, but are not limited to: papermaking processes of the type described in, for example, US-A-3,860,012; casting or “cast leaf” processes of the type described in, for example, US-A-5,724,998; dough reconstitution processes of the type described in, for example, US-A-3,894,544; and extrusion processes of the type described in, for example, GB-A-983,928. Generally, the density of sheets of homogeneous tobacco material produced by extrusion and dough reconstitution processes is greater than that of sheets of homogeneous tobacco material produced by casting processes.

[0074] Sheets of homogeneous tobacco material for use in aerosol-generating articles including capsules are preferably formed by a casting process of the type comprising: casting a slurry comprising granular tobacco and one or more binders onto a conveyor belt or other support surface, drying the cast slurry to form a sheet of homogeneous tobacco material, and removing the sheet of homogeneous tobacco material from the support surface.

[0075] Homogeneous tobacco sheet materials can be produced using different types of tobacco. For example, tobacco sheet materials can be formed using tobacco from multiple different tobacco varieties, or from different regions of the tobacco plant (e.g., leaves or stems). After processing, the sheet has constant properties and a homogeneous aroma. Individual homogeneous tobacco sheet materials with specific aromas can be produced. To produce products with different aromas, different tobacco sheet materials need to be produced. Some aromas produced by blending a large number of different chopped tobaccos in conventional cigarettes may be difficult to replicate in a single homogeneous tobacco sheet. For example, Virginia tobacco and Burley tobacco may need to be processed differently to optimize their individual aromas. It may not be possible to replicate a specific mixture of Virginia tobacco and Burley tobacco in a single homogeneous tobacco sheet. Therefore, the aerosol generating matrix may include a first homogeneous tobacco material and a second homogeneous tobacco material. By combining two different tobacco sheet materials in a single aerosol generating matrix, novel mixtures that cannot be produced by a single homogeneous tobacco sheet can be generated.

[0076] The aerosol forming agent preferably comprises at least one polyol. In a preferred embodiment, the aerosol forming agent comprises at least one of the following: triethylene glycol; 1,3-butanediol; propylene glycol; and glycerol.

[0077] Preferably, the aerosol-forming matrix of the aerosol-generated article is flavorless. If desired, the flavoring is preferably provided by a flavoring cartridge disposed upstream of a cavity between the top portion of the aerosol-generating device and the main body.

[0078] As an alternative or additional method to provide an aerosol generating article comprising a solid aerosol forming matrix, the aerosol generating apparatus may be operated in conjunction with a liquid aerosol forming matrix. The liquid aerosol forming matrix may be held in a liquid storage section. The liquid storage section may be arranged in the top portion of the aerosol generating apparatus. The liquid storage section may be arranged downstream of the flavoring cartridge. The liquid aerosol forming matrix may include a liquid aerosol forming agent. The liquid aerosol forming matrix may include a flavoring agent, such as tobacco flavoring or menthol flavoring. The liquid aerosol forming matrix may include nicotine. Preferably, in addition to the flavoring cartridge, the liquid aerosol forming matrix contained in the liquid storage section is provided. The liquid aerosol forming matrix from the liquid storage section is heated and evaporated by a heating element.

[0109] Figure 5 A cross-sectional view of another embodiment of the aerosol generating apparatus is shown. Detailed Implementation

[0110] Figure 1 A fragrance cartridge configured for use in an aerosol generation device is shown. The following will combine... Figure 3 and Figure 4 This describes an aerosol generating apparatus and the use of a fragrance cartridge within the aerosol generating apparatus. The fragrance cartridge includes a proximal portion 10, a distal portion 12, and a fragrance matrix 14. The fragrance matrix 14 is disposed between the proximal portion 10 and the distal portion 12. The proximal portion 10 and the distal portion 12 together form the shell of the fragrance cartridge. The fragrance matrix 14 is sandwiched between the proximal portion 10 and the distal portion 12.

[0111] The proximal portion 10 includes a proximal orifice 16. The proximal orifice 16 is disposed in the proximal end face 18 of the proximal portion 10. The distal portion 12 includes a distal orifice 20. The distal orifice 20 is disposed in the distal end face 22 of the distal portion 12. The fragrance matrix 14 includes a matrix orifice 24. The proximal orifice 16, the matrix orifice 24, and the distal orifice 20 are aligned with each other. A tube airflow passage 26 extends through the proximal orifice 16, the matrix orifice 24, and the distal orifice 20.

[0112] Before use, the spice container is sealed to prevent the flavoring from evaporating during storage. To seal the spice container, a removable fluid-impermeable proximal foil 56 may be positioned above the proximal orifice 16. Additionally, a removable fluid-impermeable distal foil 58 may be positioned above the distal orifice 20. Before use, the user can remove both the removable fluid-impermeable proximal foil 56 and the removable fluid-impermeable distal foil 58. After removal, an airflow channel 26 is established, allowing air to flow through the spice container.

[0113] As air flows through the spice cylinder, it comes into contact with the spice matrix 14. The flavoring agent contained in the spice matrix 14 can be entrained in the air. To increase the contact surface between the air flowing through the cylinder airflow channel 26 and the flavoring agent, one or both of the proximal portion 10 and the distal portion 12 can be configured to be porous or include porous regions. The flavoring agent can then be wicked into one or both of the proximal portion 10 and the distal portion 12, or into the porous regions of these elements.

[0114] Figure 2A The image shows the state of the fragrance cartridge before assembly. It can be seen that the airflow channel 26 extends parallel to the central axis 28 of the fragrance cartridge. In the region of the proximal orifice 16, the fragrance cartridge includes a female connecting element 30. In the region of the distal orifice 20, the fragrance cartridge includes a male connecting element 32. Alternatively, the female connecting element 30 can be arranged in the region of the proximal orifice 16, and the male connecting element 32 in the region of the distal orifice 20. The male and female connecting elements 32 and 30 are configured to allow the fragrance cartridge to be attached to the aerosol generating device.

[0115] Figure 3 An embodiment of an aerosol generating device is shown. The aerosol generating device includes a top portion 34. The top portion 34 is configured as a mouthpiece. A user can inhale the aerosol generated in the aerosol generating device through the top portion 34. The top portion 34 is arranged at a proximal or downstream end of the aerosol generating device. The aerosol generating device further includes a body 36. The body 36 may include other components, such as a power supply 46 in the form of a battery and a controller 48. These components are... Figure 5 The aerosol generating apparatus may be further included with a heating element 38 (the heating element 38 is shown in more detail below). Figure 3 and 4 Not depicted in the embodiments shown, but Figure 5 (Depicted in the embodiment shown). The spice container is also included. Figure 3 The spice cartridge is sandwiched between the top portion 34 and the main body 36. When the user inhales through the top portion 34, ambient air passes through the air inlet 50 (in...). Figure 5 (As shown in the embodiments) air is drawn into the aerosol generating device. Air is drawn through the airflow channel (in...) Figure 5 (As shown in the embodiment), and is heated together with the aerosol forming matrix by heating element 38, and an aerosol is generated by the aerosol generating device. The aerosol can then be inhaled by the user. A flavoring cartridge is arranged in the airflow channel. The flavoring cartridge adds flavoring to the air so that the flavor of the generated aerosol can be modified by the user.

[0116] The attachment of the spice cartridge and the aerosol generating device is Figure 4 Depicted in [the text]. Figure 4 In the illustrated embodiment, the male connector 32 of the fragrance cartridge is inserted into the corresponding female portion 40 of the body 36 of the aerosol generating apparatus. After the male connector 32 is inserted, the fragrance cartridge can be rotated to secure it to the body 36. Subsequently, the top portion 34 can be attached to the fragrance cartridge by way of attaching the top portion 34 to the female connector 30 of the fragrance cartridge.

[0117] Figure 5 Another embodiment of the aerosol generating apparatus is shown. The main components are similar to... Figure 3 and Figure 4 The aerosol generating apparatus shown is illustrated below. The differences will be highlighted in detail below. Figure 5 The top portion 34 of the aerosol generating apparatus shown includes a cavity 42 for receiving an aerosol generating article 44 comprising an aerosol forming matrix. A heating element 38 is disposed downstream of a fragrance cartridge in the top portion 34. The heating element 38 is configured as an induction heating element 38. The heating element 38 at least partially surrounds the cavity 42. The heating element 38 is configured to heat the aerosol forming matrix of the aerosol generating article 44.

[0118] The spice tube is sandwiched between the top portion 34 and the main body 36.

[0119] The main body 36 includes a power supply 46 and a controller 48. The controller 48 is configured to control the electrical energy supply from the power supply 46 to the heating element 38. Preferably, the power supply 46 is a battery. The main body 36 includes an air inlet 50. The air inlet 50 is fluidly connected to a main body airflow passage 52. When the spice cartridge is arranged between the main body 36 and the top portion 34, the main body airflow passage 52 of the main body 36 is fluidly connected to a cartridge airflow passage 26. The cartridge airflow passage 26 is fluidly connected to a top portion airflow passage 54. The top portion airflow passage 54 is arranged in the top portion 34. The top portion airflow passage 54 is fluidly connected to a cavity 42. Figure 5 As shown, the main airflow channel, the cylindrical airflow channel 26, and the top airflow channel 54 form a common airflow channel. During use, the user draws ambient air through the aerosol generating article 44, thereby drawing it into the air inlet 50, through the main airflow channel 52, through the cylindrical airflow channel 26, through the top airflow channel 54, and into the cavity 42. In the cavity 42, air flows through the aerosol forming matrix of the aerosol generating article 44. Due to the heating effect of the heating element 38, the air and the aerosol forming matrix are heated and aerosol is generated. During the drawing of ambient air through the cylindrical airflow channel 26, the air is enriched with flavoring agents from the flavoring matrix 14 of the flavoring cartridge. Therefore, the aroma of the aerosol leaving the system, which includes the aerosol generating device and the aerosol generating article 44, can be adjusted by a suitable flavoring cartridge.
