Description

Technical Field

[0001] This disclosure relates to aerosol delivery systems, such as, but not limited to, nicotine delivery systems (e.g., electronic cigarettes). Background Technology

[0002] Aerosol delivery systems, such as those for electronic cigarettes (e-cigarettes), generally include an aerosol-generating material (such as a chamber containing a source solid or liquid that may contain active substances and / or flavorings), from which an aerosol or vapor is generated (e.g., by thermal evaporation) for inhalation by a user. Therefore, an aerosol delivery system typically includes an aerosol-generating region housing an aerosol generator (e.g., a heating element) arranged to evaporate or aerosolize a portion of the precursor material to generate vapor or aerosol in the aerosol-generating region. When a user inhales on the device and electricity is supplied to the vaporizer, air is drawn into the device through an inlet orifice and along an inlet air passage connected to the aerosol-generating region, where the air mixes with the evaporated precursor material to form a condensed aerosol. An outlet passage connects the aerosol-generating region to an outlet in the mouthpiece, and as the user inhales on the mouthpiece, the air drawn into the aerosol-generating region continues to carry the aerosol along the outlet flow path to the mouthpiece outlet for inhalation by the user. Some electronic cigarettes may also include flavoring elements in the airflow path through the device to impart additional flavor. Such devices are sometimes referred to as mixing devices, and the flavoring elements may, for example, include a portion of tobacco arranged in the airflow path between the aerosol generation area and the mouthpiece, such that the aerosol / condensed aerosol inhaled through the device passes through this portion of tobacco before leaving the mouthpiece for the user to inhale.

[0003] WO2021074577A1 discloses an aerosol supply system, which is incorporated herein by reference.

[0004] As electronic aerosol delivery systems become more refined in the characteristics of the vapor delivered to users, the user experience with these systems continues to improve, for example in areas such as deep lung delivery, mouth contact, and performance consistency. However, there remains an attractive aerosol delivery system development approach that incorporates features that allow for adjustable system operation characteristics to target specific user preferences.

[0005] This article describes various approaches for seeking help to resolve or alleviate at least some of the problems discussed above.

[0032] Aerosol generating materials

[0033] Aerosol-generating materials are materials capable of generating aerosols, for example, when heated, irradiated, or otherwise powered. Aerosol-generating materials can be, for example, in solid, liquid, or gel form, and may or may not contain active substances and / or fragrances. In some embodiments, aerosol-generating materials may include “amorphous solids,” which may alternatively be referred to as “monolithic solids” (i.e., non-fibrous). In some embodiments, amorphous solids may be dried gels. Amorphous solids are solid materials that can retain some fluid (such as liquid) within them. In some embodiments, aerosol-generating materials may, for example, comprise from about 50 wt%, 60 wt%, or 70 wt% amorphous solids to about 90 wt%, 95 wt%, or 100 wt% amorphous solids.

[0034] Aerosol-generating materials may include one or more active substances and / or flavoring agents, one or more aerosol-forming agent materials, and optionally one or more other functional materials.

[0037] Functional materials

[0038] One or more other functional materials may include one or more of the following: pH adjusters, colorants, preservatives, adhesives, fillers, stabilizers and / or antioxidants.

[0039] matrix

[0040] The material may be present on or within the support to form a matrix. The support may be, for example, or may include, paper, cardboard, cardboard, reconstituted material, plastic material, ceramic material, composite material, glass, metal, or metal alloy. In some embodiments, the support includes a receptor. In some embodiments, the receptor is embedded within the material. In some alternative embodiments, the receptor is located on one or both sides of the material.

[0041] Consumables

[0042] Consumables are articles containing or composed of aerosol-generating materials, some or all of which are intended to be consumed by a user during use. Consumables may include one or more other components, such as an aerosol-generating material storage area, an aerosol-generating material delivery component, an aerosol-generating area, a housing, packaging paper, a nozzle, a filter, and / or an aerosol modifier. Consumables may also include an aerosol generator (such as a heater) that releases heat during use to cause the aerosol-generating material to generate an aerosol. For example, the heater may include a combustible material, a sensor, or a material that can be heated by electrical conduction.

[0043] receptors

[0044] A sensor is a material that can be heated by a changing magnetic field (such as an alternating magnetic field). A sensor can be a conductive material, such that a changing magnetic field penetrating the conductive material causes induction heating. A heating material can be a magnetic material, such that a changing magnetic field penetrating the magnetic material causes hysteresis heating. A sensor can be both conductive and magnetic, allowing it to be heated by both heating mechanisms. In this paper, a device configured to generate a changing magnetic field is referred to as a magnetic field generator.

[0045] Aerosol Modifier

[0046] Aerosol modifiers are substances typically located downstream of the aerosol generation region, configured to modify the generated aerosols, for example, by altering their taste, flavor, acidity, or other properties. The aerosol modifier can be disposed in an aerosol modifier release component operable to selectively release the aerosol modifier. For example, the aerosol modifier can be an additive or an adsorbent. For example, the aerosol modifier may include one or more of flavorings, colorings, water, and carbon adsorbents. For example, the aerosol modifier can be a solid, liquid, or gel. The aerosol modifier can be in powder, filament, or granular form. The aerosol modifier may not contain filter material.

[0047] Aerosol generator

[0048] An aerosol generator is a device configured to generate aerosols from an aerosol-generating material. In some embodiments, the aerosol generator is a heater configured to subject the aerosol-generating material to thermal energy to release one or more volatiles from the aerosol-generating material to form an aerosol. In some embodiments, the aerosol generator is configured to generate aerosols from the aerosol-generating material without heating. For example, the aerosol generator may be configured to subject the aerosol-generating material to one or more of vibration, increased pressure, or electrostatic energy.

[0049] This disclosure relates to aerosol delivery systems (which may also be referred to as vapor delivery systems), such as aerosol sprayers or electronic cigarettes. In the following description, the terms "electronic cigarette" or "electronic cigarette" may sometimes be used, but it will be understood that these terms are used interchangeably with aerosol delivery systems / devices and electronic aerosol delivery systems / devices. Furthermore, and as is common in the art, the terms "aerosol" and "vapor," as well as related terms such as "evaporation," "atomization," and "aerosolization," are generally used interchangeably.

[0050] Aerosol delivery systems (electronic cigarettes) typically (though not always) comprise modular components comprising a reusable device portion and a replaceable (disposable / consumable) cartridge portion. Typically, the replaceable cartridge portion will include aerosol generating material and an vaporizer (which may be collectively referred to as an "atomizer"), while the reusable device portion will include a power supply device (e.g., a rechargeable energy source) and a control circuitry. It will be understood that these different portions may include additional components depending on their function. For example, the reusable device portion will typically include a user interface for receiving user input and displaying operational status characteristics, and the replaceable cartridge portion may, in some cases, include a temperature sensor to aid in temperature control. The cartridge is electrically and mechanically coupled to a control unit for use, for example, using threaded, bayonet, or magnetic connections with appropriately arranged electrical contacts. When the aerosol generating material in the cartridge is depleted, or when the user wishes to switch to a different cartridge with a different aerosol generating material, the cartridge can be removed from the reusable portion, and a replacement cartridge can be attached to its appropriate position. Systems and devices that conform to this type of two-part modular configuration can generally be referred to as two-part systems / devices.

[0051] Electronic cigarettes typically have a generally elongated shape. For the purpose of providing concrete examples, some embodiments of this disclosure will include such a generally elongated two-part system employing a disposable cartridge. However, it will be understood that the basic principles described herein can be equally applied to different configurations, such as single-part systems or modular systems comprising more than two parts, refillable devices and single-use disposable items, and other overall shapes, such as high-performance devices based on so-called box-shaped patterns that typically have a box-like shape. More generally, it will be understood that some embodiments of this disclosure are based on an aerosol delivery system that is operationally configured to provide the functionality according to the principles described herein, and the construction aspects of the system configured to provide the functionality according to some embodiments of this disclosure are not particularly important. Summary of the Invention

[0052] This invention provides the claimed controller for an aerosol delivery system and a method for controlling the aerosol delivery system. The invention also provides additional embodiments as claimed in the dependent claims.

[0053] The claimed invention generally provides sub-components or subsystems suitable for use in or configured for use in aerosol delivery systems. Subsystems can generally form part of an aerosol delivery system, and specifically can form part of a reusable device and / or a consumable cartridge.

[0054] Specifically, the claimed arrangement simplifies user control of the aerosol delivery system, enabling users to more easily change the system's operating parameters and / or modes. More specifically, the claimed arrangement provides a user-friendly mechanism for changing modes without requiring users to manipulate settings or switches. Specifically, automatic restoration to the default mode conveniently avoids the need for further user interaction to switch back to the default mode and minimizes inconvenience when mode switching is unintentionally triggered. Attached Figure Description

[0055] Embodiments of this disclosure will now be described by way of example only, with reference to the accompanying drawings, in which: Figure 1 This is a schematic cross-sectional view of an aerosol delivery system according to some embodiments of the present disclosure. Detailed Implementation

[0056] This document describes aspects and features of certain examples and implementations. Some aspects and features of certain examples and implementations can be conventionally implemented, and for the sake of brevity, these aspects and features are not described in detail. Therefore, it will be understood that the undescribed aspects and features of the devices and methods discussed herein can be implemented according to any suitable conventional techniques.

[0057] Figure 1 This is a cross-sectional view of an exemplary aerosol delivery system 1 according to certain embodiments of the present disclosure, which provides an introduction to a two-piece aerosol delivery system, its components, and their functions.

[0058] The aerosol delivery system 1 comprises two main parts: a reusable part 2 and a replaceable / disposable cartridge part 4. During normal use, the reusable part 2 and the cartridge part 4 are releasably connected together at interface 6. When the cartridge part 4 is depleted or the user simply wishes to switch to a different cartridge part 4, the cartridge part 4 can be removed from the reusable part 2, and a replacement cartridge part 4 can be attached to the reusable part 2 in its proper position. Interface 6 provides the structural, electrical, and airflow path connections between the two parts 2 and 4, and can be established according to conventional techniques, such as threaded, magnetic, or bayonet fastening with appropriately arranged electrical contacts and openings. The specific manner in which the cartridge part 4 is mechanically mounted to the reusable part 2 is not important to the principles described herein, but for the sake of concreteness, it is assumed here that a magnetic connection is included. Figure 1 (Not shown in the image). It will also be understood that in some implementations, interface 6 may not support electrical connections and / or airflow path connections between the corresponding portions 2 and 4. For example, in some implementations, the aerosol generator may be located in the reusable portion 2 instead of the cartridge portion 4, or the power transfer from the reusable portion 2 to the cartridge portion 4 may be wireless (e.g., based on electromagnetic induction), thus eliminating the need for an electrical connection between the reusable portion 2 and the cartridge portion 4. Furthermore, in some implementations, the airflow through the electronic cigarette may not pass through the reusable portion 2, thus eliminating the need for an airflow path connection between the reusable portion 2 and the cartridge portion 4. In some cases, when the reusable portion 2 and the cartridge portion 4 are used together, a portion of the airflow path may be limited at the interface between a portion of the reusable portion and a portion of the cartridge portion.

[0059] According to certain embodiments of this disclosure, the cartridge / consumable portion 4 can be generally conventional. Figure 1In this embodiment, the cartridge portion 4 includes a cartridge shell 42 formed of plastic material. The cartridge shell 42 supports other components of the cartridge portion 4 and provides a mechanical interface 6 with the reusable portion 2. The cartridge shell 42 is generally circularly symmetrical about a longitudinal axis along which the cartridge portion 4 is connected to the reusable portion 2. In this example, the cartridge portion 4 has a length of approximately 4 cm and a diameter of approximately 1.5 cm. However, it will be understood that in different implementations, the specific geometry (and more generally, the overall shape) and the materials used may differ.

[0060] Inside the cartridge casing 42 is a chamber or reservoir 44 for containing aerosol-generating materials. Figure 1 In the schematic example shown, the reservoir 44 stores a supply of liquid aerosol generating material. In this example, the liquid reservoir 44 has an annular shape, having an outer wall defined by the cartridge shell 42 and an inner wall defining an airflow path 52 through the cartridge portion 4. The reservoir 44 is closed at each end using end walls to contain the aerosol generating material. The reservoir 44 can be formed according to conventional techniques; for example, it can comprise a plastic material and be integrally molded with the cartridge shell 42.

[0061] The cartridge / consumable section 4 also includes an aerosol generator 48, which is positioned toward the end of the reservoir 44 opposite the mouthpiece outlet 50. It will be understood that, as in... Figure 1 In the two-part system shown, the aerosol generator 48 can be located in either the reusable part 2 or the cartridge part 4. For example, in some embodiments, the aerosol generator 48 (e.g., a heater in the form of a core and coil arrangement as shown, a distiller formed of sintered metal fiber material or other porous conductive material, or any suitable alternative aerosol generator) can be included in the reusable part 2 and is close to a portion of the aerosol-generating material in the cartridge part 4 when the cartridge part 4 is engaged with the reusable part 2. In such embodiments, the cartridge part 4 may contain a portion of the aerosol-generating material, and when the cartridge part 4 is engaged with the reusable part 2, the aerosol generator 48, including the heater, is at least partially inserted into or at least partially surrounds that portion of the aerosol-generating material.

[0062] exist Figure 1In this example, the core 46, which contacts the aerosol generator 48, extends laterally across the cartridge airflow path 52. The end of the core extends through an opening in the inner wall of the reservoir 44 into the reservoir of liquid aerosol generating material. The opening in the inner wall of the reservoir 44 is sized to substantially match the size of the core 46 to provide a reasonable seal, preventing leakage from the liquid reservoir 44 into the cartridge airflow path without over-compressing the core 46 (which could be detrimental to its fluid transport performance).

[0063] The wick 46 and aerosol generator 48 are arranged in the cartridge airflow path 52 such that the region of the cartridge airflow path 52 near the wick 46 and heater 48 effectively defines the evaporation region of the cartridge portion 4. Aerosol-generating material in the reservoir 44 permeates into the wick 46 through the end of the wick extending into the reservoir 44 and is drawn along the wick by surface tension / capillary action (i.e., wicking). In this example, the aerosol generator 48 includes resistive wires wound around the wick 46. Figure 1 In this example, heater 48 comprises nickel-chromium alloy (Cr20Ni80) wires, and core 46 comprises a bundle of glass fibers; however, it will be understood that the specific aerosol generator configuration is not important to the principles described herein. In use, power can be supplied to aerosol generator 48 to cause a certain amount of aerosol-generating material (aerosol generating material) drawn into the vicinity of aerosol generator 48 via core 46 to evaporate. The evaporated aerosol generating material can then be entrained in the air drawn along the cartridge airflow path from the evaporation area toward mouthpiece outlet 50 for inhalation by the user.

[0064] As described above, the rate at which the aerosol generating material is evaporated by the aerosol generator 48 will depend on the amount (level) of power supplied to the aerosol generator 48. Therefore, electricity can be applied to the aerosol generator 48 to selectively generate aerosols from the aerosol generating material in the cartridge portion 4, and furthermore, the aerosol generation rate can be changed by altering the amount of power supplied to the aerosol generator 48 (e.g., through pulse width and / or frequency modulation techniques).

[0065] The reusable part 2 includes: a housing 12 having an opening defining an air inlet 28 for the electronic cigarette; an energy source 26 (e.g., a battery) for providing operating power to the electronic cigarette; a control circuitry system / controller 22 for controlling and monitoring the operation of the electronic cigarette; a first user input button 14; a second user input button 16; and a visual display 24.

[0066] The outer casing 12 may be formed of, for example, plastic or metal, and in this example, has a circular cross-section that generally conforms to the shape and size of the cartridge portion 4, to provide a smooth transition between the two portions 2 and 4 at the interface 6. In this example, the reusable portion 2 has a length of approximately 8 cm, so when the cartridge portion 4 and the reusable portion 2 are joined together, the total length of the electronic cigarette is approximately 12 cm. However, and as has already been noted, it will be understood that the overall shape and size of the electronic cigarette implementation of the embodiments of this disclosure are not important to the principles described herein.

[0067] Air inlet 28 is connected to airflow path 51 passing through reusable portion 2. When reusable portion 2 and cartridge portion 4 are connected together, reusable portion airflow path 51 further crosses interface 6 to connect to cartridge airflow path 52. Therefore, when a user inhales through mouthpiece opening 50, air is drawn in through air inlet 28, flows along reusable portion airflow path 51, crosses interface 6, passes through aerosol generation area near aerosol generator 48 (in which evaporated aerosol generation material is entrained in the airflow), along cartridge airflow path 52, and is discharged through mouthpiece opening 50 for the user to inhale.

[0068] In this example, the power source 26 is rechargeable and can be of a conventional type, such as those commonly used in electronic cigarettes and other applications requiring a relatively high current for a relatively short period of time. The power source 26 can be recharged via a charging connector (e.g., a USB connector) within the reusable housing 12.

[0069] A first user input button 14 and / or a second user input button 16 may be provided. In this example, the first and / or second user input buttons are conventional mechanical buttons, such as those including spring-loaded components that can be pressed by a user to establish electrical contact. In this respect, the input button can be considered as an input device for detecting user input, and the specific manner in which the button is implemented is not important. The button may be assigned functions such as turning the aerosol delivery system 1 on and off and adjusting user settings (such as adjusting the power supplied from the energy source 26 to the aerosol generator 48). However, including a user input button is optional, and in some embodiments, the button may not be included.

[0070] A display 24 may be provided to provide a user with visual indications of various characteristics associated with the aerosol delivery system, such as current power setting information, remaining energy source power, etc. This display can be implemented in various ways. In this example, display 24 includes a conventional pixelated LCD screen, which can be driven according to conventional techniques to display the desired information. In other implementations, the display may include one or more discrete indicators (e.g., LEDs) arranged to display the desired information, for example, through a specific color and / or flashing sequence. More generally, the provision of display 24 and the manner in which information is displayed to the user using the display are not essential to the principles described herein. For example, some embodiments may not include a visual display and / or may include other means for providing the user with information related to the operating characteristics of the aerosol delivery system (e.g., by transmitting audio signals), or may not include any means for providing the user with information related to the operating characteristics of the aerosol delivery system.

[0071] Controller 22 is suitably configured / programmed to control the operation of aerosol delivery system 1 to provide functionality according to embodiments of the present disclosure as further described herein, as well as to provide routine operational functions of aerosol delivery system 1 according to established techniques for controlling such devices. Controller (processor circuitry) 22 can be considered to logically include various sub-units / circuit system elements associated with different aspects of the operation of aerosol delivery system 1. In this example, controller 22 includes: an energy supply control circuitry for controlling the energy supply from energy source 26 to aerosol generator 48 in response to user input; a user programming circuitry 20 for establishing configuration settings (e.g., user-defined power settings) in response to user input; and other functional units / circuit systems associated with the functions of routine operational aspects of electronic cigarettes according to the principles described herein, such as a display driving circuitry and a user input detection circuitry. It will be understood that the functionality of controller 22 can be provided in various different ways, for example, by utilizing one or more suitably programmed programmable computers and / or one or more suitably configured application-specific integrated circuits / circuit systems / chips / chipsets configured to provide the desired functionality.

[0072] The functionality of controller 22 is further described herein. For example, controller 22 may include an application-specific integrated circuit (ASIC) or microcontroller for controlling an aerosol delivery device. A microcontroller or ASIC may include a CPU or microprocessor. The operation of the CPU and other electronic components is generally controlled, at least in part, by a software program running on the CPU (or other component). Such a software program may be stored in a non-volatile memory (such as ROM), which may be integrated into the microcontroller itself or provided as a separate component. The CPU may access the ROM to load and execute individual software programs as needed and as required.

[0073] The reusable portion 2 includes an airflow sensor 30 electrically connected to the controller 22. In most embodiments, the airflow sensor 30 includes a so-called "suction sensor" because it is used to detect when a user inhales on the device. In some embodiments, the airflow sensor 30 includes a switch located in the electrical path supplying power from the energy source 26 to the aerosol generator 48. In such embodiments, the airflow sensor 30 generally includes a pressure sensor configured to close the switch when subjected to a specific range of pressure, allowing current to flow from the energy source 26 to the aerosol generator 48 once the pressure near the airflow sensor 30 drops below a threshold. The threshold can be set to a value determined experimentally to correspond to a characteristic value associated with the user initiating inhalation. In other embodiments, the airflow sensor 30 is connected to the controller 22, and the controller distributes power from the energy source 26 to the aerosol generator 48 based on signals received by the controller 22 from the airflow sensor 30. The controller 22 uses the signal output from the airflow sensor 30 (which may include the capacitance, resistance or other characteristics of the airflow sensor measured by the controller 22) to control the specific manner in which the energy supply from the energy source 26 to the aerosol generator 48 can be performed in any way known to those skilled in the art.

[0074] exist Figure 1In the example shown, the airflow sensor 30 is mounted to a printed circuit board (PCB) 31, but this is not mandatory. The airflow sensor 30 may include any sensor configured to determine the characteristics of airflow in an airflow path 51 positioned between the air inlet 28 and the mouthpiece opening 50, such as a pressure sensor or transducer (e.g., a diaphragm or solid-state pressure sensor), a combined temperature and pressure sensor, or a microphone sensitive to changes in air pressure (including acoustic signals) (e.g., an electret microphone). The airflow sensor 30 is located within a sensor cavity or chamber 32, which includes an internal space defined by one or more chamber walls 34. The sensor cavity 32 includes a region located within one or more chamber walls 34, in which the airflow sensor 30 may be located wholly or partially. In some embodiments, the PCB 31 includes one of the chamber walls in a sensor housing that includes the sensor cavity / cavity 32.

[0075] The deformable membrane is configured to span an opening between the sensor cavity 32 housing the sensor 30 and a portion of an airflow path disposed between the air inlet 28 and the nozzle opening 50. According to a method further described herein, the deformable membrane covers the opening and is attached to one or more chamber walls within the chamber walls.

[0076] As further described herein, the aerosol delivery system 1 includes a communication circuitry configured to establish connectivity with one or more other electronic systems (e.g., storage tanks / charging tanks, and / or refill docks / charging docks) to enable data transfer between the aerosol delivery system 1 and the other electronic devices. In some embodiments, the communication circuitry is integrated into the controller 22, and in other embodiments, it is implemented separately (including, for example, a separate application-specific integrated circuit / circuit system / chip / chipset). For example, the communication circuitry may include a separate module to the controller 22 that provides dedicated data transfer functionality for the aerosol delivery device when connected to the controller 22. In some embodiments, the communication circuitry is configured to support communication between the aerosol delivery system 1 and one or more other electronic devices via a wireless interface. The communication circuitry may be configured to support wireless communication between the aerosol delivery system 1 and other electronic devices such as tanks, docks, computing devices (such as smartphones or PCs), cellular-enabled base stations, relay nodes providing forward connectivity to base stations, wearable devices, or any other portable or fixed device supporting wireless communication.

[0077] Wireless communication between the aerosol delivery system 1 and other electronic devices can be configured according to data transmission protocols such as Bluetooth®, ZigBee, WiFi®, Wifi Direct, GSM, 2G, 3G, 4G, 5G, LTE, NFC, RFID, or generally any other wireless and / or wired network protocol or interface. The communication circuitry may include any suitable interface for wired data connectivity, such as USB-C, micro USB, or Thunderbolt, and may include pin or contact pad arrangements configured to engage cooperating pins or contact pads that can be connected to a dock, enclosure, cable, or other external device of the aerosol delivery system 1. Individual sub-components may include one or more processors, and data processing steps may be performed on any of these processors or on a remote processor, with data communicated via wired or wireless means.

[0078] The other functions of controller 22 will now be described in more detail. Specifically, controller 22 is configured to temporarily switch aerosol delivery system 1 to an alternative mode based on suction parameters, which can be determined, for example, from sensor data received by controller 22 from the airflow or "suction" sensor 30. Controller 22 is thus configured to utilize suction parameters from the user performing suction on system 1 to switch between modes, thereby providing a user-friendly mode switching mechanism.

[0079] Depending on the parameter being measured, mode switching occurs at the appropriate time. It is important to note that for measurement to take place, some parameters (such as the duration of the aspiration) require a complete aspiration (on the first time). After a predetermined period (such as a predetermined switching delay period), or at the end of the current (first) aspiration (whose parameters are being measured), a switch can be made essentially immediately (e.g., when an abnormal aspiration / aspiration parameter is detected on System 1, such as when positive pressure from exhalation rather than inhalation is detected) to prepare for the subsequent (second) aspiration.

[0080] Controller 22 temporarily switches System 1 to an alternative mode and then reverts to the default mode, thereby avoiding the need for the user to manually switch back to the default mode and minimizing inconvenience when mode switching is unintentionally triggered. In some embodiments, controller 22 is configured to temporarily operate System 1 in alternative mode for a predetermined period of time (e.g., a single subsequent aspiration or a short period of time, such as 10 to 300 seconds) and then revert to the default mode.

[0081] The suction parameter used to trigger a temporary switch to an alternative mode can be any parameter sensed by the controller 22 or more broadly by the system 1, such as any parameter sensed by the airflow sensor 30 or other sensors. In some implementations, the suction parameter includes one or more of the following: suction duration, suction pressure, suction direction, or suction profile (a profile of airflow velocity over time, simplified to a single velocity parameter). Typically, if the suction parameter is within a given range, the system 1 operates in the default normal mode. If the suction parameter exceeds a given range (such as below (or above) a threshold), it can be considered "controlled suction" by the controller 22 temporarily switching the system 1 to an alternative mode.

[0082] In some implementations, when the suction parameter is less than and / or greater than a threshold, controller 22 is configured to temporarily operate system 1 in an alternative mode. In some implementations, multiple parameters are used, and any one or more parameters below (or above) a threshold, or a combination thereof, can be considered as “controlled suction” by which controller 22 switches system 1 to an alternative mode, for example, requiring two suction parameters to be above / below the threshold. Additionally, in some implementations, multiple thresholds and / or alternative modes can be used, and furthermore, the result of comparing parameters with thresholds can affect the alternative mode used. For example, a short suction of <1s might trigger a switch to a medium-power mode, while an extremely short suction of <0.5s might trigger a switch to a lower-power mode and / or a “discrete” mode, thereby disabling all lights on system 1.

[0083] In some implementations, controller 22 requires a two-level triggering mechanism to switch system 1 to alternative mode. For example, in some implementations, controller 22 requires: The first-level triggering mechanism when the suction parameter is less than or greater than the threshold; and The second-level triggering mechanism for subsequent suction begins within a predetermined suction interval after the first-level triggering mechanism, and then the controller 22 is configured to temporarily operate in the alternative mode (otherwise operate in the default mode).

[0084] In this two-stage trigger configuration, if the user does not intentionally initiate the alternative mode (e.g., the user is interrupted during the first suction, and therefore the first suction is shorter / weaker than expected), the user can easily avoid temporarily switching to the alternative mode by not performing suction immediately after the first suction, and the controller 22 subsequently effectively ignores the first-stage trigger mechanism. In some implementations, the predetermined suction interval is ≤2.0 seconds, ≤1.5 seconds, ≤1.0 seconds, or ≤0.5 seconds.

[0085] The inhalation duration is the time from the start to the end of an inhalation (or exhalation) and can be readily measured by an airflow or inhalation sensor 30, which detects, for example, changes in airflow, pressure, or noise relative to the environment as the user inhales or exhales on system 1, as known in the prior art. A user's inhalation duration is typically within the range of 2 to 5 seconds, 2 to 4 seconds, 1.5 to 3.5 seconds, 1 to 3 seconds, 2 to 3 seconds, or 1 to 2 seconds. Therefore, in some embodiments, any inhalation duration falling outside a fixed range or similarly below (or above) a threshold (such as ≤2.0 seconds, ≤1.5 seconds, ≤1.0 seconds, or ≤0.5 seconds) can be considered "controlled inhalation" and used by controller 22 to trigger an alternative mode.

[0086] In one implementation, when the suction duration is shorter than the threshold duration, the controller 22 is configured to temporarily replace the power mode operating system 1; and / or when the suction duration is longer than the threshold duration, the controller 22 is configured to temporarily replace the power mode operating system 1.

[0087] The suction pressure and suction direction are the pressure and direction (or pressure difference) caused by the user inhaling / breathing or exhaling at the mouthpiece of System 1. The pressure parameters can be, for example, initial values, peak values, or any average (mean / median / mode) values. Pressure and direction can be measured directly, for example, by the airflow / suction sensor 30. 500 Pa to 2000 Pa is a typical suction pressure drop. Therefore, in some embodiments, the controller 22 can trigger a temporary switch to an alternative mode using any suction pressure drop that falls outside a fixed range or is also below (or above) a threshold (such as + / -10% or + / -20%, i.e., ≤450 Pa, ≤400 Pa; or ≥2200 Pa, ≥2400 Pa). In some embodiments, the controller 22 can consider any detected exhalation (i.e., blowing air into the system, increasing the pressure therein, unlike inhalation which decreases the pressure in System 1) as a “controlled suction” trigger mechanism for switching to an alternative mode.

[0088] The suction profile includes the change in suction pressure over time as the user inhales on System 1. Controller 22 can be configured to monitor the overall trend of the user's suction profile to identify "controlled suction" that differs from normal suction. For example, if the user starts with gentle suction and then increases the pressure as the suction progresses, the change in suction pressure over time will be significantly different compared to when the user starts with forceful suction and then gradually decreases the suction intensity. The user's suction profile can be simplified, for example, to a linear relationship, or to a logarithmic, exponential, polynomial, power, or y=mx+b model. Controller 22 can determine significant deviations from typical or specific user profiles as atypical and therefore "controlled suction." For example, in some implementations, controller 22 can compare the overall pressure gradient of the current suction (e.g., increasing over time) to one or more previous suctions and consider any significant changes (such as a steeper / shallower / opposite gradient (e.g., decreasing over time)) as atypical.

[0089] Controller 22 can be configured to temporarily operate in an alternative mode when aspiration parameters deviate from a normal range (such as a fixed "normal" range for aspiration length or aspiration pressure). Controller 22 can be configured to monitor (e.g., store) aspiration parameters for a given user that vary over time, and thereby determine the duration for which the aspiration parameters deviate from the user's historical "normal" range or a portion thereof, before temporarily switching to the alternative mode. The normal range can be determined relative to a fixed or historical range or any portion (subrange) thereof (such as any average (mean / median / mode), any subrange (e.g., interquartile range), or extreme values), based on an absolute or relative threshold (e.g., a fixed 0.5 s threshold, below the duration for which almost all users might aspirate). Furthermore, the range can optionally be + / -δ, for example, based on the standard deviation of the user's aspiration history data (e.g., mean + / - 0.5 SD). The normal range for a given user can include a brief, recent history (e.g., based on the most recent 1, 2, 5, 10, 50, or 100 aspirations) to provide a cyclical normal range that adjusts over time. The controller 22 can be configured to filter / ignore potential abnormal readings by requiring any deviation from "normal" for a period of time (e.g., ≥100 ms or ≥250 ms, or to account for a significant proportion of aspiration, such as ≥2%, ≥5%, or ≥10% of the aspiration duration).

[0090] In some instances, controller 22 is configured to switch to alternative mode when the following conditions are met: The suction parameters exceed any extreme value of the user's historical normal operating range or the 5th and (corresponding) 95th percentile range by ≥5%, ≥10%, ≥15%, ≥20%, or ≥25%; The suction parameters exceed the median, mean, or mode of the user's historical normal operating range by ≥25%, ≥50%, ≥75%, ≥100%, ≥125%, or ≥150%; System 1 has two modes: a default mode and an alternative mode. The default mode is the operating mode in which System 1 is used normally. The alternative mode can be an operating mode that System 1 can operate, or it can be an inoperable mode, such as an idle mode.

[0091] In some implementations, the alternative mode includes an alternative power mode. In some implementations, in the alternative power mode, system 1 is configured to provide a different power or power profile to aerosol generator 48, thereby providing, for example, a lower or higher initial power to aerosol generator 48 compared to the default mode.

[0092] In some implementations, the alternative mode includes an alternative suction resistance mode. In some implementations, system 1 is configured to change the suction resistance for the alternative mode, for example, by changing the (effective) size of air inlet 28 and / or opening or closing one or more air inlets 28.

[0093] In some implementations, alternative modes include connectivity modes. In some implementations, system 1 is configured to selectively enable or disable one or more data transmission modules, connectivity modules, or communication modules, such as Bluetooth®, WiFi®, etc.

[0094] In some implementations, alternative modes include alternative user interface modes. In some implementations, system 1 is configured to selectively enable, disable, or modify one or more user interface elements, such as output or notification mechanisms, like light sources, displays, haptic motors, speakers / buzzers.

[0095] In some implementations, the alternative mode includes an alternative user profile. In some implementations, system 1 is configured to switch to another user profile, which may include the user's sucking curve or other settings of system 1 (e.g., preferences).

[0096] As described above, in some embodiments, the controller 22 is configured to temporarily operate the system 1 in an alternative mode for a predetermined period of time, after which it reverts to the default operating mode. The predetermined period of time is known in advance, i.e., it is known (certainly) before it is used, but it is not necessarily fixed, i.e., it may be variable. In some embodiments, the predetermined period of time is a predetermined number of suctions (e.g., one single suction, in which the controller 22 reverts to the default mode at the end of the suction) that can be detected by the suction sensor 30, or it may be a predetermined time period (such as ≤300 seconds, ≤240 seconds, ≤180 seconds, ≤120 seconds, ≤60 seconds, ≤30 seconds, ≤20 seconds, or ≤10 seconds).

[0097] In other embodiments, controller 22 is configured to operate system 1 in an alternative mode until a specific user input or gesture is detected or a change in the orientation of system 1 is detected, such as when a user presses user input buttons 14, 16 to perform a gesture (such as rotating system 1, for example, 90°, 180°, or 360°), or changes its orientation (e.g., from substantially horizontal to substantially vertical, or vice versa).

[0098] Exemplary scenario

[0099] Now, a non-limiting exemplary scenario for implementing the above embodiments will be described.

[0100] In the first example, the alternative mode is a lower power mode, ideally suited for use in an enclosed space. When controller 22 determines that the user performs an atypically short first aspiration (shorter than the threshold aspiration duration (e.g., ≤1 s)) and then rapidly (i.e., within a predetermined aspiration interval (e.g., within 1 s)) a longer subsequent (second) aspiration, controller 22 senses this (e.g., using aspiration sensor 30) and immediately and temporarily reduces the power supplied to aerosol generator 48 for a period of time (e.g., a fixed time period) until user input or gesture is detected or until the second aspiration ends (which can be detected using aspiration sensor 30 and / or a directional sensor indicating the removal of the aspiration direction by detection system 1). The subsequent (third) aspiration then returns to normal because controller 22 resumes the default mode after the second aspiration ends. Conversely, the alternative mode could be a higher power mode, for example, one with the same or different aspiration duration and / or aspiration interval parameters.

[0101] This first exemplary configuration allows for virtually instantaneous power changes without requiring the user to fiddle with any settings, menus, or switches. The requirement for subsequent pumps to occur within a short, predetermined pump interval means that system 1 is unlikely to be accidentally switched to an alternative (in this case, low-power) mode—which would require the user to intentionally take an atypical (very short) first pump followed quickly by a longer (normal) second pump. If no such second pump is detected within the predetermined pump interval, controller 22 ignores the short first pump and continues operating at the normal power setting for subsequent pumps.

[0102] After switching to low-power mode, System 1 automatically returns to normal operating mode after a certain period of time (e.g., a predetermined number of aspirations or a predetermined time), thus avoiding the need for the user to manually switch back to the default mode and minimizing inconvenience when mode switching is unintentionally triggered. Therefore, this configuration allows for the selection of alternative power modes based on successive aspirations as needed and when required.

[0103] In the second instance, the alternative mode is a discrete operating mode, which temporarily disables or reduces the intensity of one or more output mechanisms (such as a haptic motor / buzzer, speaker / beeper, or light, such as an LED), similar to switching a mobile phone to "silent" mode—which would be useful, for example, if a user wants to smoke in a quiet, dark environment (such as a movie theater) without disturbing others.

[0104] In the third instance, the alternative mode is the connection mode, in which the system is temporarily switched to a wireless connection pairing mode, for example, in which Bluetooth®, NFC, WiFi® or other data transmission / communication modules are turned off in the default operating mode to save power until the suction parameters exceed or fall below a threshold (e.g., suction duration < 1 s or the user makes a call on system 1).

[0105] In some implementations, system 1 includes a sensor for identifying aerosol-generating materials. Controller 22 can also be configured to adjust any parameters / settings based on this identification, such as one or more settings for a default mode and / or alternative modes; and / or thresholds, predetermined time periods, and / or predetermined aspiration intervals for aspiration parameters. Therefore, these parameters / settings can be adjusted based on the aerosol-generating materials in use, thereby customizing the experience to optimize consistency across different aerosol-generating materials. System 1 may include a lookup table for parameters / settings for various aerosol-generating materials, or be able to wirelessly transmit data to, for example, a connected smartphone to obtain suitable parameters / settings.

[0106] In some implementations, the controller 22 has a cycle time of 1 ms to 10 ms to provide a highly responsive system.
