Description

Technical Field

[0001] This disclosure relates to an electronic aerosol delivery system, such as an electronic cigarette, and to a control unit for the system. This disclosure also relates to an electronic aerosol delivery system, such as a nicotine delivery system (e.g., an electronic cigarette). Background Technology

[0002] Electronic vapor delivery systems, such as those in e-cigarettes and other electronic nicotine delivery systems, typically include a vapor precursor material, such as a reservoir of a source liquid containing a formulation, typically nicotine. This vapor precursor material is atomized, for example, by thermal atomization, for the user to inhale. When the user inhales on the device, a control unit operates a battery to provide power to a heater. This activates the heater, causing the vapor precursor material to atomize and then be inhaled by the user.

[0003] Therefore, this type of e-cigarette typically includes two consumables: a vapor precursor material to be atomized and the battery power. Regarding the vapor precursor material, once depleted, any residue or parts previously containing it can be discarded to allow replacement with new vapor precursor material (e.g., within the cartridge). Regarding the battery power, e-cigarettes usually provide some form of electrical connector to receive power from an external charging device, thus allowing the battery within the e-cigarette to be recharged.

[0004] Most e-cigarettes are powered by rechargeable lithium-ion batteries (or accumulators), which can be found not only in e-cigarettes but also in a wide variety of devices. (Note that the terms "battery" and "accumulator" are used interchangeably in this document because, due to the limited space within an e-cigarette, such batteries typically consist of only one accumulator.) Conventional lithium-ion batteries used in e-cigarettes typically have an energy storage capacity ranging from 70 mAh to 3500 mAh, depending on factors such as device size.

[0005] The design of aspects related to the atomizer components of the vapor supply system can play an important role in the overall performance of the system, such as in helping to reduce the possibility of users accidentally and inconveniently stopping their e-cigarettes with complete exhaustion.

[0006] Electronic aerosol supply systems, such as those for electronic cigarettes (e-cigarettes), typically include a reservoir of a source liquid containing a formulation, typically nicotine, which is atomized into an aerosol, for example, by thermal atomization. Therefore, the aerosol source for the aerosol supply system may include a heater having a heating element arranged to receive the source liquid from the reservoir, for example, via wicking / capillary action. When a user inhales on the device, electricity is supplied to the heating element to atomize the source liquid near the heating element, thereby generating an aerosol for the user to inhale. Such devices typically have one or more air inlets positioned remotely from the mouthpiece end of the system. When a user inhales on a mouthpiece connected to the mouthpiece end of the system, air is drawn in through the air inlets and flows through the aerosol source. A flow path exists connecting the aerosol source and the opening in the mouthpiece, such that the air drawn through the aerosol source continues along the flow path to the mouthpiece opening, carrying some aerosol from the aerosol source. Air carrying aerosols exits the aerosol supply system through the nozzle opening for the user to inhale.

[0007] Typically, such electronic aerosol supply systems are equipped with heating components suitable for heating the source liquid to form an aerosol. One example of such a heating component is a core and coil heating assembly, which consists of a coil of wire (typically a nickel-chromium alloy NiCr 8020) wound or coiled around a core (the core typically comprises a bundle of fibers, such as cotton fibers, extending along the longitudinal axis of the coil). The end of the core extends on either side of the coil and is inserted into a reservoir of the source liquid.

[0008] In such systems, a power source with limited capacity (such as a battery) powers a heater to generate the aerosol to be delivered to the user. As the battery ages, its capacity decays, affecting performance in terms of the number of inhalations achievable when fully charged. Therefore, the system's performance declines over time, but in most cases, the user receives no information about this capacity decay. Consequently, the user may experience situations where the device runs out of power, something that wouldn't have happened before, causing anxiety for the aerosol delivery system user.

[0009] This article describes various approaches designed to help solve these problems. Summary of the Invention

Suitable thermal agents may be, but are not limited to, vanillyl ether, and suitable coolants may be, but are not limited to, eucalyptol, WS-3.

[0049] Aerosol forming agent materials may include one or more components capable of forming aerosols. In some embodiments, aerosol forming agent materials may include one or more of the following: glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3-butanediol, erythritol, meso-erythritol, ethyl vanillate, ethyl laurate, diethyl octanoate, triethyl citrate, triacetin, a mixture of glyceryl diacetate, benzyl benzoate, benzyl phenyl acetate, glyceryl tribocate, lauryl acetate, lauric acid, myristic acid, and propylene carbonate.

[0050] One or more other functional materials may include one or more of pH adjusters, colorants, preservatives, binders, fillers, stabilizers and / or antioxidants.

[0051] 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. Aerosol modifiers can be disposed in aerosol modifier release components, operable to selectively release the aerosol modifier.

[0052] For example, aerosol modifiers can be additives or adsorbents. For example, aerosol modifiers may include one or more of fragrances, colorants, water, and carbon adsorbents. Aerosol modifiers can be, for example, solids, liquids, or gels. Aerosol modifiers can be in the form of powders, filaments, or granules. Aerosol modifiers may not contain filter materials.

[0053] In some implementations, the aerosol supply system includes modular components comprising an aerosol supply device (sometimes referred to as a reusable part) and articles containing aerosol-generating materials (sometimes referred to as consumables or replaceable parts). However, in other implementations, the aerosol supply system may include a one-piece device, wherein the articles and the aerosol supply device are integrally formed.

[0054] Typically, a non-combustible aerosol supply system may include a non-combustible aerosol supply device and consumables for use with the non-combustible aerosol supply device. In some embodiments, this disclosure relates to consumables comprising aerosol-generating materials and configured for use with a non-combustible aerosol supply device. These consumables are sometimes referred to as articles in this disclosure.

[0055] In some implementations, non-combustible aerosol supply systems, such as their non-combustible aerosol supply devices, may include a power source and a controller. For example, the power source may be a power supply.

[0056] In some embodiments, a non-combustible aerosol supply system may include an area for receiving consumables, an aerosol generator, an aerosol generation area, a housing, a nozzle, a filter, and / or an aerosol modifier.

[0057] Consumables are articles comprising 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 (or storage section), an aerosol-generating material transport component, an aerosol-generating area, a housing, packaging paper, a filter, a suction nozzle, and / or an aerosol modifier. Consumables may also include an aerosol generator, such as a heater, which releases heat during use to cause the aerosol-generating material to generate an aerosol. The heater may, for example, comprise a combustible material, a material that can be heated by electrical conduction, or a sensor. A sensor is a material that can be heated by penetrating a changing magnetic field, such as an alternating magnetic field. A sensor may be a conductive material such that penetration by a changing magnetic field results in inductive heating of the heating material. A heating material may be a magnetic material such that penetration by a changing magnetic field results in hysteresis heating of the heating material. A sensor may be both conductive and magnetic, such that the sensor can be heated by both heating mechanisms. In this document, a device configured to generate a changing magnetic field is referred to as a magnetic field generator.

[0058] An aerosol generator is a device configured to generate aerosols from aerosol-generating material. In some implementations, the aerosol generator is a heater configured to subject the aerosol-generating material to heat energy, causing the material to release one or more volatiles to form an aerosol. In some implementations, the aerosol generator is configured to generate aerosols from 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.

[0059] Figure 1 It is a cross-sectional view taken through the aerosol supply system 1 provided according to certain aspects of this disclosure. Figure 1 The aerosol supply system 1 is adapted to atomize liquid aerosol generating materials (sometimes referred to as source liquids or e-liquids). However, as stated above, the principles of this disclosure are not limited to the aerosol supply system 1 adapted to atomize liquid aerosol generating materials. For example, the principles of this disclosure can be implemented in an aerosol supply device adapted to atomize solid or gel aerosol generating materials.

[0060] Figure 1 The aerosol supply system 1 shown includes two main components: an aerosol supply device 2 and a replaceable / disposable cartridge 4 (which is an example of an article). Figure 1 The aerosol supply system 1 is an example of a modular construction of the aerosol supply system 1. In this respect, the aerosol supply device 2 and the cartridge 4 can be joined or separated from each other at the interface 6. However, as mentioned above, the principles of this disclosure also apply to other constructions of the aerosol supply system 1, such as those in which the device 2 and the cartridge 4 can be integrally formed as a one-piece or integrated structure (or in other words, the aerosol supply device 1 is provided with an integrally formed aerosol generating material storage area).

[0061] The aerosol supply system 1 is generally elongated and cylindrical in shape. The dimensions of the aerosol supply system 1 can be set to be similar to those of a conventional cigarette. However, it should be understood that the overall size and shape of the aerosol supply system 1 are not important to the principles of this disclosure. In some other implementations, the aerosol supply system 1 can adopt a different overall shape; for example, the aerosol supply device 2 can be based on a so-called box-type high-performance device, which typically has a shape closer to a box.

[0062] Device 2 includes components typically designed to have a longer lifespan than cartridge 4. In other words, device 2 is designed to be used sequentially with multiple cartridges 4. Cartridge 4 includes components (such as aerosol-generating materials) that are consumed when aerosol is formed during use of the aerosol supply system 1 to deliver it to the user.

[0063] exist Figure 1 In the exemplary modular configuration, device 2 and cartridge 4 are releasably connected together at a first interface 6. When the aerosol-generating material in cartridge 4 is depleted or the user simply wishes to replace it with a different cartridge 4 (e.g., a cartridge containing a different aerosol-generating material), cartridge 4 can be removed from device 2 and a replacement cartridge 4 can be attached to and placed in place. Interface 6 provides a structural connection between device 2 and cartridge 4 and can be established using generally conventional techniques, such as based on threads, latching mechanisms, bayonet fasteners, or magnetic couplings. In some implementations, interface 6 may also provide an electrical connection between device 2 and cartridge 4 using suitable electrical contacts. The electrical connection can allow the supply of electrical power and / or data to / from cartridge 4.

[0064] It should also be understood that in some implementations, the cartridge 4 can be refillable. That is, when the cartridge 4 is depleted, the aerosol generating material can be refilled into the cartridge 4 using a suitable mechanism, such as a one-way refill valve (not shown). The cartridge 4 can be removed from the device 2 for refilling. In other instances, the cartridge 4 can be configured to be refilled while attached to the device 2.

[0065] In the implementation of the aerosol supply system 1 as a one-piece or integrated system, the aerosol supply system 1 can be designed to be discarded after the aerosol generating material is depleted. Alternatively, the aerosol supply system 1 can be equipped with a suitable mechanism, such as a one-way valve, to refill the integrated cartridge 4 (or the integrated aerosol generating material storage area) with aerosol generating material.

[0066] exist Figure 1 In the middle, the cartridge part 4 includes a cartridge shell 42, an aerosol generating material storage area 44, an aerosol generator 48, an aerosol generating material transmission component 46, an outlet or mouthpiece opening 50, and an air path 52.

[0067] The cartridge housing 42 supports the other components of the cartridge 4 and provides a mechanical interface 6 for engagement with the device 2. The cartridge housing 42 is made of a suitable material, such as plastic or metal. In the described implementation, the cartridge housing 42 is approximately circularly symmetrical about the longitudinal axis along which the cartridge 4 is attached to the device 2. In this example, the cartridge 4 has a length of approximately 4 cm and a diameter of approximately 1.5 cm. However, it should be understood that the specific geometry and, more generally, the overall shape may vary in different implementations. The cartridge 4 includes a first end generally defined by the interface 6 and a second end opposite the first end, which includes a mouthpiece opening 50. The second end, including the mouthpiece opening 50, is intended to be received in / by the user's mouth and can therefore be referred to as the mouthpiece end of the cartridge 4.

[0068] An aerosol generating material storage area 44 (sometimes also called a reservoir 44) is provided inside the cartridge casing 42. Figure 1 The cartridge 40, or more specifically the reservoir 44, is configured to store a liquid aerosol generating material, which may be referred to herein as a source liquid, e-liquid, or liquid. The source liquid may be generally conventional and may contain nicotine and / or other active ingredients, and / or one or more flavorings, as described above. In some implementations, the source liquid may not contain nicotine.

[0069] In this example, the reservoir 44 has an annular shape, its outer wall defined by the cartridge shell 42 and its inner wall defining an air path 52 through the cartridge 4. The reservoir 44 is closed at each end by an end wall to contain liquid. The reservoir 44 can be formed using conventional techniques; for example, the reservoir can comprise a plastic material and be integrally molded with the cartridge shell 42.

[0070] The cartridge 4 also includes an aerosol generator 48. The aerosol generator 48 is a device configured to generate an aerosol from an aerosol-generating material (e.g., a source liquid). Optionally, the cartridge 4 includes an aerosol-generating material transfer component 46 configured to transfer the aerosol-generating material from an aerosol-generating material storage region 44 (e.g., a reservoir 44) to the aerosol generator 48. In some implementations, particularly those where the aerosol generator 48 is in fluid communication with the aerosol-generating material storage region 44, the aerosol-generating material transfer component 46 may not be necessary.

[0071] Aerosol generator 48 is configured to cause aerosol-generating material to generate aerosols. In some implementations, aerosol generator 48 is a heater 48. Heater 48 is configured to subject aerosol-generating material to heat energy, causing the aerosol-generating material to release one or more volatiles to form an aerosol. For example, heater 48 may be in the form of a resistance wire or resistance line designed to allow current to flow between the ends of the heater, or in the form of an inductive element designed to generate heat upon exposure to an alternating magnetic field. However, in other implementations, aerosol generator 48 is configured to cause aerosol-generating material to generate aerosols without heating. For example, aerosol generator 48 may be configured to subject the aerosol-generating material to one or more of vibration, increased pressure, or electrostatic energy.

[0072] The aerosol generating material transport element 46 is configured to transport the aerosol generating material from the aerosol generating material storage area 44 (reservoir 44) to the aerosol generator 48. The properties of the aerosol generating material can determine the form of the aerosol generating material transport element 46. For example, for liquid or viscous gel aerosol generating materials, the aerosol generating material transport element 46 is configured to transport the liquid or viscous gel aerosol generating material using capillary action or a suitable pumping mechanism. For example, the aerosol generating material transport element 46 may include porous materials (e.g., ceramics) or fiber bundles (e.g., glass or cotton fibers) capable of transporting liquid / viscous gels using capillary action.

[0073] exist Figure 1 In the described implementation, the aerosol generator 48 is a heater 48 in the form of a wire coil (such as a nickel-chromium alloy (Cr20Ni80) wire). Figure 1 In this implementation, the aerosol generating material transport element 46 is a core 46 in the form of a fiber bundle (such as glass fiber). Figure 1As can be seen, heater 48 is wound around the generally central region of core 46, such that heater 48 is positioned close to core 46 and thus close to any liquid contained within core 46. In some implementations, aerosol generator 48 may include a porous ceramic core 46 and conductive traces disposed on the surface of the porous ceramic core serving as heater 48. In still other implementations, heater 48 and core 46 may be combined into a single component, for example, multiple sintered steel fibers forming a planar structure.

[0074] In the described example, heater 48 and core 46 are positioned towards the ends of reservoir 44. In this example, core 46 extends laterally across cartridge air path 52, with both ends extending into liquid reservoir 44 through openings in the inner wall of reservoir 44. The openings in the inner wall of reservoir 44 are sized to approximately match the dimensions of core 46 to provide a reasonable seal against leakage from liquid reservoir 44 into cartridge air path 52 without overcompressing core 46, which could negatively impact fluid transfer performance. Core 46 is thus configured to transfer liquid from reservoir 44 to the vicinity of heater 48 via capillary effect.

[0075] The core 46 and heater 48 are arranged in the cartridge air path 52 such that the area of ​​the cartridge air path 52 surrounding the core 46 and heater 48 effectively defines the atomization zone of the cartridge 4. This atomization zone is the area where the cartridge 4 first generates atomized gas. In use, electricity can be supplied to the heater 48 to atomize a certain amount of liquid drawn through the core 46 to the vicinity of the heater 48.

[0076] The aerosol is delivered to the user via a mouthpiece opening 50 located at the mouthpiece end of the cartridge 4. During use, the user can place their lips on or around the mouthpiece end of the cartridge 4 and inhale air / aerosol through the mouthpiece opening 50. More specifically, air is drawn into the air path 52, then flows along the air path and passes through the heater 48, where the aerosol is entrained in the inhaled air. The mixed aerosol / air is then inhaled by the user through the mouthpiece opening 50. Although Figure 1 The mouthpiece end of the cartridge 4 is shown as an integral part of the cartridge 4, but a separate mouthpiece component can be provided, which can be releasably attached to the end of the cartridge 4.

[0077] The device 2 includes an outer housing 12, an optional indicator 14 (i.e., an output mechanism), an intake sensor 16 located in a chamber 18, a controller or control circuit 20, a power source 26, an air inlet 28, and an air path 30.

[0078] Device part 2 includes: an outer housing 12 having an opening that defines an air inlet 28 for the aerosol supply system 1; a power source 26 for providing operating power to the aerosol supply system 1; a controller or control circuit 20 for controlling and monitoring the operation of the aerosol supply system 1; and an inhalation sensor (suction detector) 16 located in a chamber 18. Device 2 also includes an optional indicator 14.

[0079] The outer casing 12 can be made of, for example, plastic or metal, and in this example, the outer casing has a circular cross-section, and its shape and size approximately match the shape and size of the cartridge 4 to achieve a smooth transition between the two components at the interface 6. In this example, the device 2 has a length of approximately 8 cm, so when the cartridge 4 and the device 2 are connected, the total length of the aerosol supply system 1 is approximately 12 cm. However, and as already noted, it should be understood that the overall shape and size of the aerosol supply system 1 of this disclosure are not essential to the principles described herein.

[0080] The outer housing 12 also includes an air inlet 28 connected to an air path 30 extending through the device 2. When the device 2 and the cartridge 4 are connected, the device air path 30 further connects to the cartridge air path 52 via an interface 6. In this regard, the interface 6 is also arranged to connect the respective air paths 30 and 52, allowing air and / or aerosol to flow along the connected air paths 30 and 52. In other implementations, the device 2 does not include an air path 30, but the cartridge 4 includes an air path 52 and a suitable air inlet that allows air to enter the air path 52 when the cartridge 4 and the device 2 are connected.

[0081] In this example, the power source 26 is battery 26. Battery 26 can be rechargeable and can be of a generally conventional type, such as those commonly used in aerosol supply devices and other applications that require providing relatively high current over a relatively short period of time. Battery 26 can be, for example, a lithium-ion battery. Battery 26 can be recharged via a suitable charging connector (e.g., a USB connector) located at or within the outer housing 12. Alternatively or additionally, device 2 may include suitable circuitry to facilitate wireless charging of battery 26. In other examples, power source 26 can be an alternative component suitable for storing energy, such as a supercapacitor.

[0082] The control circuit or control unit 20 is appropriately configured / programmed to control the operation of the aerosol supply system 1. The control circuit 20 can be considered as logically comprising various sub-units / circuit elements associated with different aspects of the operation of the aerosol supply system, and can be implemented by setting up a control chip of the form of a (micro)controller, processor, ASIC, or similar type. The control circuit 20 can be arranged to control any function associated with the aerosol supply system 1. By way of non-limiting examples only, in addition to other functions such as controlling visual indicators (e.g., LEDs) / displays, communication functions for communicating with external devices, etc., the function may also include charging or recharging the battery 26, discharging the battery 26 (e.g., for providing power to the heater 48). The control circuit 20 can be mounted to a printed circuit board (PCB). It should also be noted that the functions provided by the control circuit 20 can be distributed across multiple circuit boards and / or distributed across components not mounted to a PCB, and these additional components and / or PCBs can be located within the aerosol supply device 2, as appropriate. For example, the function in control circuit 20 for controlling the (re)charging function of battery 26 can be set separately from the function for controlling the discharging function of battery 26 (e.g., set separately on different PCBs).

[0083] As noted above, when the device 2 and the cartridge 4 are connected together at the interface 6, the interface 6 provides an electrical connection between the device 2 and the cartridge 4. More specifically, the electrical contacts on the device 2 that connect to the power source 26 are electrically connected to the electrical contacts on the cartridge that connect to the heater 48. Therefore, under the proper control of the control circuit 20, power from the power source 26 can be supplied to the heater 48, thereby energizing the heater 48 and allowing the heater 48 to atomize the liquid held in the core 46 near the heater 48.

[0084] exist Figure 1 In this example, the aerosol supply device 2 includes a chamber 18 with a built-in inhalation sensor 16, which in this example is a pressure sensor. The pressure sensor 16 is in fluid communication with an air path 30 in the device 2 (e.g., the chamber 18 branches off from the air path 30 in the device 2). When a user inhales at the nozzle end of the aerosol supply system 1, and air subsequently flows into the device 2 via the air inlet 28 and along air paths 30, 52, the pressure sensor 16 detects a pressure change (drop) within the chamber 18. If the pressure drop is significant enough, the pressure sensor 16 (or the associated control circuitry 20) detects that the user has inhaled.

[0085] In response to the detection of a user inhalation, the aerosol supply system 1 is controlled to generate aerosol. In other words, when pressure sensor 16 detects a pressure drop in pressure sensor chamber 18, control circuitry 20 responds by supplying sufficient power from battery 26 to aerosol generator 48, thereby atomizing the liquid held within core 46. This is an example of an aerosol supply system known as "inhalation-actuated." Pressure sensor 16 can be used to start and / or stop power supply to heater 48 (e.g., when pressure sensor detects the absence of inhalation). It should be understood that inhalation sensor 16 can be any suitable sensor, such as an airflow sensor, used to sense when a user inhales at the mouthpiece end of cartridge 4 and air subsequently flows along air paths 30, 52. Therefore, the presence of chamber 18 is optional, and the presence of chamber 18 can depend on the characteristics of the selected inhalation sensor 16. For example, an airflow sensor can be located within airflow paths 30, 52.

[0086] In other implementations, the aerosol supply device 2 includes a button or other user-actuable mechanism. When the button or other user-actuable mechanism is actuated by a user, the control circuit 20 supplies electrical energy to the heater 48, as described above. This is an example of an aerosol supply device referred to as "button-actuated". The button can be used to start and / or stop power supply to the heater 48 (e.g., when the user releases the button). In some implementations, both the button (or other user-actuable mechanism) and the inhalation sensor 16 can be used simultaneously to control the supply of electrical energy to the heater 48, for example, requiring both button pressing and pressure drop (indicating the presence of inhalation) to occur simultaneously before power is supplied to the heater 48.

[0087] The aerosol supply device 2 also includes an optional indicator 14 (i.e., an output mechanism). The indicator 14 can be configured to provide feedback to the user of the aerosol supply device 1. For example, the indicator 14 can indicate information such as whether the aerosol generator 48 is currently active, the remaining battery life (of the battery 26), the total number of starts of the aerosol generator 48, and the amount of liquid remaining in the reservoir 44. Alternatively or additionally, the indicator 14 can display operating parameters of the aerosol supply device 2. In some implementations, the indicator 14 can be configured in conjunction with an input mechanism (such as one or more buttons or a touchscreen display) that allows programming and / or modification of the operating parameters of the aerosol supply device 1. The indicator 14 can be a visual indicator (such as a display or one or more LEDs), an audio indicator (such as a speaker), or a tactile indicator (such as a haptic motor).

[0088] Note that although in some implementations the aerosol-generating material is heated, for example, via heater 48 to form an aerosol, thereby potentially raising the temperature of the generated aerosol above ambient temperature through atomization, this is not the only way to raise the aerosol temperature above ambient temperature. For example, in some implementations, the aerosol generator 48 may indirectly cause heating of the aerosol-generating material during aerosol generation. In some implementations, an additional heater located downstream of the aerosol generator 48 (relative to the air / aerosol flow during intake) may be configured to heat the aerosol before it leaves the aerosol supply system 1. Therefore, it should be understood that the principles of this disclosure are not necessarily limited to the aerosol supply system 1 including a heater as the aerosol generator 48.

[0089] According to this disclosure, the aerosol supply device 1 is capable of generating aerosols from aerosol generating materials using an aerosol generator, and includes a rechargeable power source and a recharge circuit.

[0090] Figure 2 This is based on some embodiments of the present disclosure. Figure 1 A schematic diagram of certain electrical components (including electronic components) of the aerosol supply system 1. Figure 2 Depicting typically located Figure 2 The various components in the aerosol supply device 2 of the aerosol supply system are reusable (rather than disposable). However, in some implementations, at least some of the electrical components may be located in the atomizing cartridge 4.

[0091] like Figure 2 As shown, control unit 20 is (directly or indirectly) connected to electrical (and mechanical) interface 6 (as discussed above), power switch 212, power source 26 such as a battery (as discussed above), non-volatile memory 218 (e.g., ROM), communication interface 217, timer (clock) 219, indicator 14 (as discussed above), inhalation sensor 16 (as discussed above), recharging circuit 220, and recharging interface 221. Control unit 20 may be located on a PCB, and may also be used to mount other components, such as memory 218, inhalation sensor 16, power switch 212, communication interface 217, and / or recharging circuit 220, depending on the specific internal configuration of control unit 20. Alternatively, these components may be located on one or more other PCBs (or on other forms of mounting).

[0092] Figure 2Some (but not all) electrical connections between different components are shown. For example, the inhalation sensor 16 may receive power from the power source 26 via its connection to the control unit 20, or alternatively, a separate power connection (not shown) may be provided that connects directly from the power source 26 to the inhalation sensor 16.

[0093] Control unit 20 includes a processor (such as a CPU) and memory (ROM and RAM). The operation of control unit 20 and other electronic components is typically, at least in part, controlled by software programs running on the processor (or, where appropriate, on other electronic components). Such software programs may be stored in non-volatile memory 218, which may be integrated into control unit 20 itself or set as a separate component (e.g., on a PCB). The processor can access the ROM to load and execute the various software programs when needed. Control unit 20 also includes appropriate interfaces (and control software) for interacting with other devices, such as the inhalation sensor 16.

[0094] The control unit 20 utilizes indicator 14 as an output device to indicate a condition or status within the aerosol supply device 2, such as a low battery warning. Different signals can be configured to indicate different conditions or statuses. For example, indicator 14 can be a speaker, which provides different signals by utilizing different tones or beeps of varying pitch and / or duration, and / or by providing multiple such beeps or tones. Indicator 14 can be provided by other forms of output devices as supplements to or alternatives to a speaker. For example, light output may be present at one or more other locations on the aerosol supply device 2. When indicator 14 includes an indicator light, different signals can be provided by, for example, various combinations of light (in the case of light output at more than one location), flashing sequences, colors, or brightness levels. In some instances, indicator 14 may include a display configured to provide notifications to the user using, for example, pictures and / or alphanumeric characters (e.g., forming words and sentences).

[0095] Communication interface 217 (in) Figure 2The interface marked "Comms 217" can be a wired or wireless connection to allow the aerosol supply device 2 to communicate with external devices. For example, the communication interface 217 may support one or more of Bluetooth, Wi-Fi (IEEE 802.11 series), and / or Near Field Communication (NFC) for establishing wireless communication. Alternatively or additionally, the communication link may support wired communication, which may be implemented via interface 6, recharge interface 221 (as discussed below), and / or some other communication facility. The communication interface can be used in particular to allow external devices (such as computing devices) to provide and update control settings on the aerosol supply device 2, and / or obtain status and usage information from the aerosol supply device 2.

[0096] As noted above, the aerosol supply system 1 provides an air path (not shown) from the air inlet through the aerosol supply device 2, past the inhalation sensor 16 and the aerosol generator 48 (located in the atomizer), to the mouthpiece outlet 50 of the atomizing cartridge 4. Therefore, when a user inhales through the mouthpiece of the aerosol supply system, the control unit 20 detects this inhalation based on information from the inhalation sensor. In response to this detection, the control unit 20 supplies power from the battery or accumulator 26 to the aerosol generator 48, which then heats and atomizes the liquid in the core for the user to inhale.

[0097] Power source 26 is connected to aerosol generator 48 via power switch 212 and interface 6 (including a corresponding interface on the atomizing cartridge 4). Power switch 212 supports the flow (and on / off) of a relatively large current supplied from power source 26 to power aerosol generator 48 (typically about 1 amp or greater). Power switch 212 is controlled by control unit 20. For example, control unit 20 may close power switch 212 in response to inhalation sensor 16 sensing airflow through aerosol supply device 2, thereby allowing power to flow from battery to heater. Conversely, control unit 20 may open power switch 212 in response to inhalation sensor 16 sensing that airflow through aerosol supply device 2 has now stopped, thereby terminating the flow of power from battery to heater. Furthermore, control unit 20 may use switch 212 to implement a PWM scheme as described above to regulate the amount of power supplied from power source 26 to aerosol generator 48 during inhalation.

[0098] The recharge circuit 220 is used to recharge the rechargeable power source 26 when the aerosol supply device 2 is connected to an external power supply device (not shown). For example, the recharge circuit 220 may be configured to receive power from the external power supply device and, if the power from the external power supply device is supplied with appropriate parameters (e.g., within upper and lower tolerance limits of current and voltage), direct that power to charge the power source 26. The recharge circuit 220 may also be configured to assess the state of the power source 26 to determine whether recharging is necessary or safe. For example, if the power source is close to full charge (e.g., based on measured voltage or current), if the charging time exceeds a threshold, or if the temperature of the power source exceeds an upper or lower threshold limit, recharging to the recharge circuit 220 may be prevented or limited.

[0099] like Figure 2 As shown, the recharging circuit 220 is connected to the recharging interface 221, which is configured to interface with an external power supply device (directly or indirectly via an adapter or computing device). The recharging interface 221 allows power to be transferred from the external power supply device (not shown) directly or via the recharging circuit 220 to the power source 26. The recharging interface 221 can be configured to form a wired circuit with a corresponding connection to the external power supply device, adapter, charging cable, or computing device. Therefore, the recharging interface 221 can be at least partially exposed on the surface of the aerosol supply device 2. For example, the recharging interface 221 can be provided by a USB interface (such as a USB-C interface) or other types of connectors. Alternatively, the recharging interface 221 can be provided by a wireless interface 22, which is disposed in the housing 12 of the aerosol supply device 2 and configured to wirelessly receive power from an external power supply device (directly or indirectly via an adapter or computing device).

[0100] Furthermore, in some instances, the recharge interface 221 can also be configured to transmit data. For example, the recharge interface 221 can allow communication between the aerosol supply device 2 and an external device (such as an adapter or computing device). The recharge interface 221 can be connected to a communication interface 217, enabling the communication interface 217 to communicate with the external device using the recharge interface 221 (e.g., a connection provided by the recharge interface 221). This communication can be transmitted via a separate dedicated data transmission line (connection), and / or via the power transmission line (connection) of the recharge interface 221.

[0101] In some other instances, recharge interface 221 may be absent, and instead, recharge circuitry 220 may interact with interface 6 to allow recharging of power source 26. In other words, recharge interface 221 and interface 6 are combined into a single interface configured to simultaneously allow power supply from power source 26 to aerosol generator 48 and power transfer from an external power supply to power source 26.

[0102] It should be understood that Figure 2 The electrical configurations shown are provided by way of example only, and those skilled in the art will recognize many possible variations. For example, some aerosol supply devices 2 may not have the communication interface 217 and / or recharging circuit 220, while in other instances, the communication interface 217 and / or recharging circuit 220 may be at least partially combined with the control unit 20.

[0103] The functions of control unit 20 can be distributed across one or more components, which together act as a controller. For example, a PCB combined with power source 26 can be configured to control battery recharging, such as detecting and thereby preventing voltage or current overload and / or excessive charging time, and also to control battery discharge, for example, to prevent the battery from being over-discharged to the extent that it would be damaged.

[0104] Figure 3 This is a schematic diagram of an aerosol supply system 1 according to some embodiments of the present disclosure; the aerosol supply system 1 includes an aerosol supply device 2 and a computing device 300, the aerosol supply device including Figure 2 The electronic components shown (and other components may also exist, such as those related to...) Figure 1 (Described component). Figure 3 Components of the aerosol supply device 2 and related Figure 1 and 2 The components described are the same.

[0105] Figure 3 The computing device 300 is configured to be communicatively connected to the aerosol supply device 2 (with regard to...) Figure 2 (The aerosol supply device discussed is the same as the one mentioned above). This aerosol supply device includes a rechargeable power source 26 and a recharging circuit 220 for recharging the rechargeable power source 26 when connected to an external power supply. The computing device 300 includes a control unit 320, a communication interface 310, a memory 330, and an indicator 340. The computing device 300 may be, for example, a smartphone, a personal computer, or a charging case for the aerosol supply device 2.

[0106] The operation of components such as control unit 320, communication interface 310, memory 330, and indicator 340 can be similar to that described above. Figure 2The operation of the corresponding named components of the aerosol supply device 2 discussed herein is basically similar. "Corresponding naming" means that each corresponding component of the device shares a name associated with the shared function performed by that component (e.g., indicators 14 and 340 both perform an indicating function). Although in Figure 3 There is no such labeling, but the corresponding component of the aerosol supply device 2 can be referred to as the "first" component (e.g., the first control unit 20, the first communication interface 217, the first memory 218, and the first indicator 14), while the corresponding component of the computing device 300 can be referred to as the "second" component (e.g., the second control unit 320, the second communication interface 310, the second memory 330, and the second indicator 340), and vice versa.

[0107] Control unit 320 includes a processor such as a CPU and memory 330 (ROM and RAM). The operation of control unit 20 and other electronic components is typically, at least in part, controlled by software programs running on the processor (or, where appropriate, on other electronic components). Such software programs may be stored in non-volatile memory 330, which may be integrated into control unit 20 itself or set as a separate component (e.g., on a PCB). The processor can access the ROM to load and execute the various software programs when needed. Control unit 20 also includes appropriate interfaces (and control software) for interacting with other devices.

[0108] The control unit 320 can utilize the indicator 340 as an output device to indicate the status or condition within the aerosol supply device 2 and / or the computing device 300, such as a low battery warning or other status information for the aerosol supply device 2. Specifically, the indicator 340 can be used to indicate information about... Figure 1 and 2 The information discussed in indicator 14. Indicator 340 may provide a visual indicator (such as a display or one or more LEDs), an audio indicator (such as a speaker), or a tactile indicator (such as a tactile motor).

[0109] Communication interface 310 (in) Figure 3The communication interface (marked "Comms 310") can be a wired or wireless connection to allow the computing device 300 to communicate with the aerosol generating device 2, and optionally, to communicate with other external devices or servers. For example, the communication interface 310 may support one or more of Bluetooth, Wi-Fi (IEEE 802.11 series), and / or Near Field Communication (NFC) for establishing wireless communication. Alternatively or additionally, the communication link may support wired communication, which may be implemented via interface 6, recharge interface 221, and / or some other communication facilities. The communication interface 310 can be used in particular to allow the computing device 300 to provide and update control settings on the aerosol supply device 2, and / or obtain status and usage information from the aerosol supply device 2. The communication interface 310 can also be used in particular to allow the computing device 300 to receive updates related to the aerosol supply device 2 from servers or other external devices.

[0110] Preferably, the computing device 300 is a remote computing device capable of establishing a wireless communication link with the aerosol supply device 2. "Remote" means that the computing device 300 and the aerosol supply device 2 can communicate even when physically separated (e.g., not physically connected). For example, the communication interface 310 of the computing device 300 and the communication interface of the aerosol supply device 217 can be configured to establish wireless communication (e.g., both can support one or more of Bluetooth, Wi-Fi, and / or NFC). This allows the aerosol supply device 2 to send data (e.g., user behavior data related to the recharging of a rechargeable power source) to the computing device 300 via a wireless communication link without requiring a physical connection between the two devices 2 and 300.

[0111] Figure 4 This is a schematic diagram of an aerosol supply system 1 according to some embodiments of the present disclosure; the aerosol supply system 1 includes an aerosol supply device 2 and a computing device 300, the aerosol supply device including Figure 2 and 3 The electronic components shown (and other components may also exist, such as those related to...) Figure 1 (Described component). Figure 4 Components of the aerosol supply device 2 and related Figure 3 The components described are the same. (And) Figure 3 Compared to the computing device 300, Figure 4The computing device 300 also includes a docking port 410 for docking (e.g., connecting or holding) the aerosol supply device 2 to the computing device 4, and optionally includes a power source 420 configured to recharge the aerosol supply device 2 via a recharging interface 221. The computing device 300 may be a docking station, a charging dock, or a base (e.g., a charging accessory intended for use in substantially one location), or a charging case (e.g., a portable accessory configured to be carried by a user so that it can be charged when needed). Figure 4 The remaining features of the computing device 300 and related to Figure 3 The described features are basically the same.

[0112] A docking port 410 is used to dock the aerosol supply device 2 with the computing device 300. "Docking" means that the computing device 300 is configured to connect to the aerosol supply device 2 via the docking port. In some instances, the docking port 410 may be shaped to receive a portion of the aerosol supply device 2. For example, the docking port 410 may include a recess in the housing of the computing device 300, the cross-section of which is substantially similar to, but possibly slightly larger than, the cross-section of the portion of the aerosol supply device 2 received within the recess. In some instances, the docking port 410 may include connection features (e.g., a latch or a magnet) configured to attach to or engage with the aerosol supply device 2. The aerosol supply device 2 may or may not include corresponding connection features (e.g., a corresponding latch feature or a corresponding magnet) that interact with the connection features of the docking port 410.

[0113] In some instances, docking port 410 may be configured to electrically connect to the recharging circuitry 220 of the aerosol supply device when the aerosol supply device 2 is docked in docking port 410 (e.g., recharging interface 221 may facilitate the formation of electronic circuitry between computing device 300 and aerosol supply device 2). In other instances, docking port 410 may be configured to wirelessly connect computing device 300 to the recharging circuitry 220 of the aerosol supply device when the aerosol supply device 2 is docked in docking port 410 (e.g., recharging interface 221 may allow wireless power transfer from computing device 300 to aerosol supply device 2). “Configured to” means that docking port 410 may be configured to position or guide the aerosol supply device 2 to ensure a suitable connection (wired or wireless) is established between the aerosol supply device 2 and computing device 300.

[0114] like Figure 4As shown, the computing device 300 includes a power source 420 that can supply power from the computing device 300 to the aerosol supply device 2. Therefore, the computing device 300 is configured to act as an external power supply device to transfer power from the computing device 300 to the aerosol supply device 2. In these examples, the computing device 300 may be a charging case (e.g., a portable accessory configured to charge the aerosol supply device 2 as needed). The docking station 410 and the recharging interface 221 may be configured to facilitate the transfer of electrical energy from the computing device 300 to the aerosol supply device 2.

[0115] In some other instances, the power source 420 of the computing device 300 may be absent, or the power source 420 may not be used to charge the aerosol supply device 2. Alternatively, in some instances, the computing device 300 may be configured to allow electrical energy from an external power source to charge the aerosol supply device 2. For example, the computing device 300 may receive electrical energy from an external power source and control the supply of that energy to the aerosol supply device 2. In these instances, the computing device 300 may be, or can act as, an adapter or charging dock for the aerosol supply device 2.

[0116] In some instances, communication interface 310 (in) Figure 4 The communication interface 310 (labeled "Comms 310") can be configured to form a wired connection to allow the computing device 300 to communicate with the aerosol generating device 2. For example, the communication link can support wired communication via the recharge interface 221 when the aerosol supply device 2 is received by the docking port 410. Alternatively, in some instances, the communication interface 320 can be configured to perform short-range wireless communication (e.g., according to the NFC protocol) with the aerosol generating device 2 when the aerosol supply device 2 is received by the docking port 410. The communication interface 310 can be used in particular to allow the computing device 300 to provide and update control settings on the aerosol supply device 2, and / or to obtain status and usage information from the aerosol supply device 2. The communication interface 310 can also be used in particular to allow the computing device 300 to receive updates related to the aerosol supply device 2 from a server or other external device.

[0117] Figure 5 This is a flowchart illustrating some embodiments of the present disclosure for notifying a user when to use an aerosol supply system (e.g., regarding...). Figures 1 to 4 The discussion focuses on a method for recharging a rechargeable power source for an aerosol supply system. Figure 5 The method described illustrates various aspects of the operation of the control circuit of aerosol supply system 1. Specifically, Figure 5 This involves a method executed by a control circuit. Figure 5The method is used to notify users when to recharge the rechargeable power source of the aerosol supply system, which uses an aerosol generator to generate aerosols from aerosol generating materials.

[0118] "Control circuitry (e.g., a control unit)" refers to electronic circuitry capable of performing or operating operations and functions. Control circuitry may include processors (such as CPUs) and memories (ROM and RAM). The operation of control circuitry is typically controlled, at least in part, by software programs running on the processor (or, where appropriate, on other electronic components). Such software programs may be stored in non-volatile memory, which may be integrated into the control circuitry itself or set up as a separate component (e.g., mounted on a PCB). The processor may access the ROM when needed to load and execute the various software programs (e.g., to perform operations related to the method steps described below).

[0119] In some instances, the control circuitry can be provided by either the control unit 20 of the aerosol supply device 2 or the control unit 320 of the computing device 300. In other instances, the control circuitry can be provided by both the control unit 20 of the aerosol supply device 2 and the control unit 320 of the computing device 300. In other words, the method can be performed by one or both of the aerosol supply device 2 and the computing device 300. For example, the steps of the method can be performed entirely by the control units 20 and 320 of one of the devices, or one or more steps can be performed by the control units 20 and 320 of one device, while the remaining steps can be performed by the control units 320 and 20 of the other device.

[0120] In light of the above, in some instances, the aerosol supply system 1 (including a rechargeable power source 26, a recharging circuit 220, and a control circuit) may include Figure 2 The aerosol supply device 2, in this case, performs Figure 5 The control circuit for the method steps is the control unit 20 of the aerosol supply device 2. In other examples, the aerosol supply system 1 (including a rechargeable power source 26, a recharging circuit 220, and a control circuit) may include... Figure 3 or Figure 4 The aerosol supply device 2 and the computing device 300, in this case, perform Figure 5 The control circuit for the method steps is the control unit 320 of the computing device 300, or it can be a combination of the control unit 20 of the aerosol supply device 2 and the control unit 320 of the computing device 300.

[0121] Figure 5 The method begins with step S1, which includes acquiring a rechargeable power source 26 (or, in some instances, such as according to...) Figure 4 In some instances of those examples, user behavior data related to the recharging of power source 420 is obtained. "Acquiring user behavior data related to the recharging of rechargeable power source 26" means that the control circuit (e.g., control unit 20 or control unit 320) receives or records data related to when the user recharges the rechargeable power source.

[0122] User behavior data related to the recharging of rechargeable power source 26 may include the date and time of charging events and the duration of these charging events, as well as other data related to the charging of power source 26 (e.g., the total duration for which delivery device 2 is connected to the charger, where the total duration is longer than the actual charging duration, because recharging itself stops once power source 26 is fully charged). In some instances, user behavior data may include information indicating when power source 26 of aerosol supply device 2 is being recharged and when power source 2 is not being recharged (e.g., by incrementally recording whether charging is in progress, such as recording daily by minute or hour).

[0123] For example, the control circuitry can interact with the recharging circuitry 220 to determine when an external power source (e.g., a charging adapter or charging case) is connected, and can record time values ​​associated with charging events (e.g., start-up, stop-up, and charging duration) to generate user behavior data related to the recharging of the power source 26. In some other instances, a different entity than the control circuitry can generate user behavior data related to the recharging of the rechargeable power source, and the control circuitry can obtain such data from that different entity. For example, the control circuitry could be a control unit 320 of the computing device 300, which could be configured to obtain user behavior data from the recharging circuitry 220 or the control unit 20 of the aerosol supply device 2.

[0124] The acquired user behavior data can be stored in a memory accessible to the control circuitry. For example, the acquired user behavior data can be stored in the memory 218 of the aerosol supply device 2, and / or the acquired user behavior data can be stored in the memory 330 of the computing device 300. The acquired user behavior data can be stored in the relevant memory using logs, tables, or other suitable data structures. For example, the data structure can contain information identifying the date and time of the charging event initiated by the user.

[0125] By acquiring user behavior data related to the recharging of power source 26, the control circuit can establish a record of when (e.g., time and date) the user recharges power source 26 of aerosol supply device 2. Storing the acquired user behavior data in memory allows for the retrieval and analysis of the established records.

[0126] Figure 5 The method continues to step S2, which includes determining the default recharging mode of the rechargeable power source 26 based on the acquired user behavior data. "Determine" refers to the control circuitry (e.g., Figure 2 , Figure 3 or Figure 4 Control unit 20, or Figure 3 or Figure 4 The control unit 320 is configured to analyze or process the acquired user behavior data to calculate or otherwise identify a default recharging mode (e.g., using data from timer 219, and / or using other data, such as location data).

[0127] For example, the control circuitry can process the acquired user behavior data to create or update a model that represents or otherwise defines a default pattern of user behavior related to the recharging of power source 26 (i.e., the default pattern is provided by the model in some instances). In some instances, the model can be updated whenever a specific event occurs, such as when the user initiates the recharging of power source 26, or when the control circuitry, provided by the control unit 320 of computing device 300, acquires a new set of user behavior data related to one or more new recharging events initiated by the user. In other instances, the model can be updated periodically (e.g., once a day or once a week) or according to different criteria (e.g., updated at least once every 10 recharging events).

[0128] "Default recharging mode of rechargeable power source 26" refers to data defining the regular or normal time periods during which the power source is charged, including, for example, the times of day when charging is typically initiated, and / or the regularity of power source 26 charging. In some instances, the default mode may identify the likely or potential times during which power source 26 of aerosol supply device 2 is expected to be recharged. In some instances, the default recharging mode includes the times of day when the rechargeable power source is connected to an external power supply and the duration thereof. For example, control circuitry may process or analyze user behavior data to determine when the user typically charges power source 26 and use this information to create a default mode to predict when the user expects or may charge power source 26 in the future.

[0129] Phrases such as “rechargeable power source connected to an external power supply,” “charging started,” “charging session started,” and “recharging started” are used interchangeably to indicate that an action has been performed that causes power to be supplied to power source 26. For example, to charge power source 26, the user connects power source 26 to an external power source (e.g., power source 420), thereby turning on or starting charging of power source 26 (e.g., starting a charging session). Therefore, when it is mentioned that the user has started charging, it indicates that the user has taken an action such as connecting rechargeable power source 26 to an external power supply.

[0130] In some instances, the default mode may identify when the user typically charges the power source 26 at a fixed time of day (e.g., 10 p.m.), or when the user typically charges the power source several hours after disconnecting the aerosol supply device 2 from the charger (e.g., 10 hours later). In some instances, the default recharge mode includes the dates of the week when the rechargeable power source is (regularly) connected to an external power supply.

[0131] In some instances, a default pattern can represent different behaviors on different days within a week, month, or year. For example, based on user behavior data, a default pattern might show that the number and / or duration of user-initiated charging events are related not only to specific points in time but also to specific days within a week. The model can then leverage these correlations to provide a more accurate estimate of expected energy usage (and its distribution). Furthermore, these events can be correlated with publicly available information or user-provided information, such as potential non-working days, including weekends and public holidays.

[0132] For example, a default pattern could identify that power source 26 is charged more frequently on certain dates than on other dates (e.g., charging occurs in the mornings and evenings from Monday to Friday). Similarly, a default pattern could identify that user behavior related to initiating charging is more regular on certain dates than on other dates (e.g., more regular on Monday to Friday than on Saturday or Sunday). It should be understood that the identified user routine pattern is specific to that user; however, the same processing and analysis techniques can be applied regardless of the specific user. For example, while some users do not work on Saturdays and Sundays, other users may work on Saturdays and Sundays. The same processing and analysis techniques can identify behavior related to weekdays and non-weekdays, regardless of the user's working days.

[0133] In some instances, control circuitry (e.g., control unit 20 or control unit 320) is configured to acquire location indications of the aerosol supply system and / or the user. In these instances, the default recharging mode includes location indications. For example, the default mode may also include other information, such as location indications of the aerosol supply device and / or the user when the power source is recharging and / or when recharging is initiated. For instance, the default mode could identify that the user is charging the device at one or more locations, and that the device will not be charged when the user moves away from those locations.

[0134] The default model described in this paper can be based on various statistical and computational structures of varying complexity, such as principal component analysis (PCA), correlation models, neural networks, etc. Note that the default model can be provided by a model that continuously improves as device usage increases. For example, at a given point in time, the model can predict certain expected behaviors related to recharging over a set time period (e.g., the following week). The actual recharging behavior during that time period can then be accessed and compared to the predictions. If there are discrepancies between the predictions and actual usage, these discrepancies can be leveraged using any suitable machine learning techniques to help refine and improve the model.

[0135] In some instances, the default mode may be provided by the aerosol supply device 2 itself and / or by an external computing device 300 (such as a smartphone, tablet computer, etc.). Figure 3 ) or charging case (see Figure 4 The default mode or its representation can be presented (e.g., via a suitable display) on the aerosol supply device 2 or (e.g., via a suitable display) on an external computing device. In some instances, the user interface of the external computing device (such as a smartphone) is often much more powerful than that of the aerosol supply device 2, for example, in the case of a touchscreen interface, and such a device often also has more powerful processing capabilities.

[0136] Another possibility is that the default pattern is generated by the aerosol supply device 2 or an external computing device 300 via the Internet or another suitable network-accessible server. In this case, user behavior data can be uploaded to the server for analysis and modeling. In some instances, the determined default pattern is generated externally to the aerosol supply device 2 and computing device 300 (if present) by control circuitry communicating with the server, and the generated default pattern is then transmitted back to the aerosol supply device 2 for storage and subsequent use (e.g., in step S3).

[0137] Figure 5The method further proceeds to step S3, which includes, based on the determined result, triggering the generation of a notification to inform the user when the rechargeable power source should be recharged. In some instances, "triggering the generation of a notification" means generating a signal (e.g., a pulse) that results in the generation of a notification (e.g., the signal may be an instruction, or a component may be configured to generate a notification in response to the signal).

[0138] The notification can take any suitable form, depending on the available functionality of the aerosol supply device 2 (e.g., depending on the nature of the indicator 14). For example, the aerosol supply device 2 can provide a specific audio warning (one or more beeps) via a speaker, or it can set one or more indicator lights. In some instances, the notification can be generated by an external computing device 300 (e.g., by indicator 340). Another possibility is communication via communication interface 217 with another external device (e.g., the user's smartphone), where the other external device generates the notification (e.g., by using an application on the smartphone, and the application provides the relevant notification to the user).

[0139] "Notifying the user when to recharge the rechargeable power source based on a determined result" refers to signaling the user based on a determined result to indicate when to recharge the rechargeable power source. For example, notification instructions or other methods make the user aware that the power source 26 should be charged at a target time or within a target time period.

[0140] In some instances, the notification informs the user that they should recharge immediately, or that they should recharge at any time after the notification is generated. In some of these instances, "triggering the generation of a notification to inform the user when to recharge the rechargeable power source" means triggering the generation of a notification to inform the user to recharge the rechargeable power source.

[0141] In some other instances, the notification informs the user that they should recharge at a future time. In some of these instances, "triggering a notification to inform the user when to recharge the rechargeable power source based on a determined result" means triggering a notification to inform the user to recharge their rechargeable power source at or before a first time point, where the first time point is determined by the control circuitry in response to a determined default mode.

[0142] In response to the notification, the user can choose an appropriate action, such as charging the device during the time period indicated by the notification or before the time specified in the notification. For example, in response to the notification, the user can... Figure 4 Connect the aerosol supply device 2 to the docking port 410 of the computing device 300.

[0143] In some instances, the notification can be a natural language message when it is provided by an indicator capable of providing a natural language format (e.g., text on a display or voice emitted via a speaker). For example, the notification could include messages such as “Consider charging your device within the next hour” or “Consider charging your device before 10 p.m.”. In some instances, the notification may also reference a default pattern determined in step S2 to encourage habit formation. For example, the notification could include messages such as “Consider charging your device before 10 p.m. to align with your daily routine.”

[0144] In some instances, the notification may not be in natural language format. For example, the notification may include one or more user-perceptible signals (e.g., a beeping, buzzing, or flashing light) that the user can interpret to take appropriate action. For instance, the user may interpret the notification via a user manual or information printed on a portion of the casing near the source of the notification. For example, the notification may be described, in conjunction with the user manual or printed information, as an instruction on when the user should recharge the rechargeable power source (e.g., “If notification #1 appears, charge within 1 hour”). It should be understood that various notifications (e.g., different signal sequences) may be provided to instruct the user on different time periods for recharging the rechargeable power source.

[0145] The notification is based on a predetermined default pattern (step S2), meaning it is generated based on information from the default pattern. In some instances, the default pattern can define typical or standard (i.e., default) user behavior related to recharging. For example, the default pattern can identify the regular or normal time period (e.g., time and / or date) when a user recharges power source 26, or the time periods when a user typically initiates a charging session (e.g., at night) and the time periods when a user typically does not initiate a charging session (e.g., when the user may be working or asleep).

[0146] In some instances, the control circuitry defines one or more thresholds and / or conditions based on the determination of a default mode. In these instances, the control circuitry may trigger the generation of a notification when one or more thresholds or conditions are met or exceeded. In some instances, the control circuitry may define one or more time thresholds that should trigger the generation of a notification. For example, the control circuitry may set a time threshold based on the default mode that corresponds to the start time of a period when the user frequently begins charging (i.e., connecting device 2 to an external power source). After the time threshold is exceeded, the control circuitry may trigger the generation of a notification until the user connects aerosol supply device 2 to the power source. In some instances, the control circuitry may stop triggering notification generation if a second threshold (e.g., the second threshold is based on the default mode and corresponds to the end time of a period when the user frequently begins charging) has been exceeded.

[0147] In some instances, the control circuitry may define one or more conditions on which the generation of a notification depends. In some instances, the control circuitry may determine conditions related to the location of the aerosol supply device 2 (with built-in power source 26) and / or the user, and may trigger the generation of a notification if it receives information indicating that the aerosol supply device 2 and / or the user meet location conditions (e.g., the user is at home or in the office).

[0148] In some instances, the control circuitry can determine conditions relating to the use of the aerosol supply device and, if it receives information indicating that the device has been used according to those conditions, can trigger the generation of a notification. For example, the condition could require that the device has been used within a certain period (e.g., within 30 minutes, preferably within 15 minutes, and most preferably within 5 minutes (based on timer 219, etc.)), which can be advantageous because the user and the aerosol supply device 2 may be very close, especially if notification is provided by the indicator 14 of the aerosol supply device 2. Alternatively, the condition could require that the device has not been used within a certain period (e.g., more than 30 minutes since the last use, and preferably more than 60 minutes since the last use (based on timer 219, etc.)), which could indicate that the user does not intend to use the aerosol supply device 2 for an extended period.

[0149] In some instances, these conditions may be related to the movement of the aerosol supply device 2 (in this case, the aerosol supply device 2 includes sensors capable of detecting movement), the interaction of the user with an application or program on an external device (e.g., computing device 300), and / or the amount of usage per day (e.g., based on a count of the number of times the aerosol generator 48 is started). In some instances, the control circuitry triggers the generation of a notification when both the threshold and the condition are met. For example, the control circuitry may trigger the generation of a notification if a time threshold has been exceeded (e.g., a time of day has passed past the start time of a charging session where the user typically turns on the power source 26) and a condition is met (e.g., the user or device is in a specific location and the user has used the device, or alternatively, the device has not been used for a period of time).

[0150] In some instances, the control circuitry (e.g., control unit 20 or control unit 320) can recognize from the default mode that the user typically begins charging the power source 26 at a specific time or within a specific time period, and trigger the generation of a notification to remind the user in advance that their usual charging time or time period is approaching. In some instances, different notifications can be provided based on the remaining time until the user's usual charging time or time period (e.g., threshold alarms for one hour, 30 minutes, and 15 minutes). It should be understood that if the user begins charging the power source 26 before the notification expires, no notification will be issued.

[0151] In some instances, control circuitry (e.g., control unit 20 or control unit 320) can identify from a default mode that a user typically begins charging the power source within a specific time period (i.e., between specific time points) and trigger the generation of a notification reminding the user that their typical charging period has begun and / or is currently occurring. For example, if a user typically charges the power source during a certain time period (e.g., between 7 p.m. and 10 p.m.), the control circuitry can trigger one or more notifications during that time period to remind the user to charge the power source. Notifications can be provided at the beginning of the time period, in the middle of the time period, and / or near the end of the time period, such as when the time period is 90% complete (e.g., generating notifications based on a threshold corresponding to progress throughout the time period). In some instances, the default mode can represent a predicted (most likely) time point within the time period when the user begins charging the power source, and the controller can provide notifications that correspond to that predicted time.

[0152] In some instances, control circuitry (e.g., control unit 20 or control unit 320) can identify from the default mode that the user has not started charging the power source within a fixed time period or at a fixed time point (i.e., the user has deviated from the default mode) and can trigger the generation of a notification to the user instructing them to connect the rechargeable power source to an external power supply to begin charging. In other words, the control circuitry is configured to trigger the generation of a notification in response to a deviation from the default recharging mode (e.g., when the rechargeable power source is not connected to an external power supply). For example, the default mode might indicate that the user typically starts charging power source 26 within a set time period. The control circuitry can identify that the user has not yet started charging power source 26 within that time period and, in response, can trigger the generation of a notification to inform the user that they should recharge power source 26.

[0153] In some instances, the control circuitry is configured to provide multiple notifications based on the degree of deviation from the default mode (e.g., providing a notification one hour after the expected end of the period identified from the default mode, and providing a notification two hours after the expected end of the period identified from the default mode, etc.). In some instances, the user can block further notifications by charging the power source (e.g., by connecting device 2 to an external power supply), or by interacting with aerosol supply device 2, computing device 300, or other external devices to silence further notifications.

[0154] In some instances, the control circuitry can trigger the generation of a notification based on location data in a default mode. For example, the control circuitry can receive information indicating that the user and / or the aerosol supply device 2 is located at a location where the user frequently charges the power source 26, and in response, trigger the generation of a notification to inform the user when to recharge the power source (e.g., charge immediately, or charge within the next hour).

[0155] In some instances, the control circuitry can trigger the generation of a notification based on location and time data in a default mode (e.g., based on conditions and thresholds). For example, the control circuitry can receive information indicating that the user and / or aerosol supply device 2 is located at a location where the user frequently charges the power source 26, and information indicating that the period during which the user frequently charges the power source is about to begin, has begun, or has ended. In response, the control circuitry triggers the generation of a notification to inform the user when to recharge the power source (e.g., charge immediately, or charge within the next hour).

[0156] Similarly, in some instances, the control circuitry can identify when a period in which the user frequently charges the power source is about to begin or has already begun, but the user is not in their usual location, and in response, it will not trigger a notification generation or will trigger a delayed notification until information is received indicating that the user and / or the aerosol supply device is located at a location where the power source 26 is frequently charged.

[0157] Figure 5 That concludes the method.

[0158] Based on the principles of this disclosure, an aerosol supply component (including an aerosol supply system 1) is also provided for generating aerosols from an aerosol generating material using an aerosol generating component (including an aerosol generator 48). The aerosol supply component includes: a rechargeable power component including a power source 26; a recharging component including a recharging circuit 220 for recharging the rechargeable power component when connected to an external power supply device; and a control component including a control circuit 20 configured to: acquire user behavior data related to the recharging of the rechargeable power component; determine a default recharging mode for the rechargeable power component based on the acquired user behavior data; and trigger the generation of a notification based on the determination result to inform the user when to recharge the rechargeable power component.

[0159] Therefore, an aerosol supply system for generating aerosols from aerosol generating materials using an aerosol generator has been described. The aerosol supply system includes: a rechargeable power source; a recharging circuit for recharging the rechargeable power source when connected to an external power supply; and a control circuit configured to: acquire user behavior data related to the recharging of the rechargeable power source; determine a default recharging mode for the rechargeable power source based on the acquired user behavior data; and, based on the determination result, trigger the generation of a notification to inform the user when to recharge the rechargeable power source.

[0160] Therefore, an aerosol supply device for generating aerosols from aerosol generating materials using an aerosol generator is also described. The aerosol supply device includes: a rechargeable power source; a recharging circuit for recharging the rechargeable power source when connected to an external power supply; and a control circuit configured to: acquire user behavior data related to the recharging of the rechargeable power source; determine a default recharging mode for the rechargeable power source based on the acquired user behavior data; and, based on the determination result, trigger the generation of a notification to inform the user when to recharge the rechargeable power source.

[0161] Therefore, a computing device for communicatively connecting to an aerosol supply device for generating aerosols using an aerosol generator with an aerosol generating material is also described. The aerosol supply device includes a rechargeable power source and a recharging circuit for recharging the rechargeable power source when connected to an external power supply. The computing device includes control circuitry configured to: acquire user behavior data related to the recharging of the rechargeable power source; determine a default recharging mode for the rechargeable power source based on the acquired user behavior data; and trigger the generation of a notification based on the determination result to inform the user when to recharge the rechargeable power source.

[0162] Therefore, a method for notifying a user when to recharge a rechargeable power source of an aerosol supply system is also described. This aerosol supply system uses an aerosol generator to generate aerosols from an aerosol-generating material. The method includes: acquiring user behavior data related to the recharging of the rechargeable power source; determining a default recharging mode for the rechargeable power source based on the acquired user behavior data; and triggering a notification based on the determination result to inform the user when to recharge the rechargeable power source.

[0163] While the above embodiments focus in some respects on specific exemplary aerosol supply systems, it should be understood that the same principles can also be applied to aerosol supply systems employing other technologies. For example, although Figure 1 While the focus is on liquid aerosol generating materials, it should be understood that the aerosol supply apparatus or system according to embodiments of this disclosure can alternatively use solid-based or gel-based aerosol generating materials. In other words, the specific manner in which various aspects of the aerosol supply system function are not directly related to the basic principles of the examples described herein.

[0164] According to another aspect of this disclosure, an aerosol supply system is described, configured to determine the effective capacity of a power source, representing the capacity decay of the power source over time. The effective capacity can be based on an output from a power source measurement circuit capable of measuring the electrical properties of the power source to provide its current maximum potential capacity, and can also be based on a pre-acquired (e.g., from the manufacturer) default maximum potential capacity of the power source. The aerosol supply system can perform an action based on the determined effective capacity, particularly when the effective capacity is considered to be below a threshold. The action taken by the aerosol supply system can guide the user to take subsequent actions regarding the use of the aerosol supply system. For example, the aerosol supply system can alert the user when the effective capacity of the power source is below a threshold amount and / or when the typical average number of inhalations achievable after the power source is fully charged is below a threshold amount. In this way, the user can be informed when the power source is no longer suitable for use and should be replaced.

[0165] The following description will focus on embodiments in which the aerosol supply system is an aerosol supply system in which a source liquid, as an aerosol generating material, is atomized to generate an aerosol for inhalation by a user. In these embodiments, the article is commonly referred to as a cartridge. As described above, the cartridge is mechanically engaged with the aerosol supply device. However, it should be understood that the principles of this disclosure apply to aerosol supply systems capable of atomizing various aerosol generating materials, such as solids or gels, as described above. More generally, the principles of this disclosure apply to aerosol supply systems used with any suitable aerosol generating material.

[0166] Figure 6 It is a cross-sectional view taken through the aerosol supply system 501 provided according to certain aspects of this disclosure.

[0167] Figure 6 The aerosol supply system 501 shown includes two main components: an aerosol supply device 502 and a replaceable / disposable cartridge 504 (which is an example of a consumable or article). Figure 6 The aerosol supply system 501 is an example of a modular construction. In this respect, the aerosol supply device 502 and the cartridge 504 can be joined or separated from each other at the interface 506. However, as mentioned above, the principles of this disclosure also apply to other constructions of the aerosol supply system 501, such as those in which the device 502 and the cartridge 504 can be integrally formed as a one-piece or integrated structure (or in other words, the aerosol supply device 501 is provided with an integrally formed aerosol generating material storage area or portion).

[0168] The aerosol supply system 501 is generally elongated and cylindrical in shape. The dimensions of the aerosol supply system 501 can be set to be similar to those of a cigarette. However, it should be understood that the overall size and shape of the aerosol supply system 501 are not important to the principles of this disclosure. In some other implementations, the aerosol supply system 501 can adopt a different overall shape; for example, the aerosol supply device 502 can be based on a so-called box-type high-performance device, which typically has a shape closer to a box.

[0169] Device 502 includes components generally designed to have a longer lifespan than cartridge 504. In other words, device 502 is designed to be used in sequence with multiple cartridges 504. Cartridge 504 includes components (such as aerosol generating materials) that are consumed when the aerosol is formed during use of the aerosol supply system 501 for delivery to the user.

[0170] exist Figure 6In an exemplary modular configuration, device 502 and cartridge 504 are releasably coupled together at a first interface 506. When the aerosol-generating material in cartridge 504 is depleted or the user simply wishes to replace it with a different cartridge 504 (e.g., one containing a different aerosol-generating material), cartridge 504 can be removed from device 502, and a replacement cartridge 504 can be attached to and placed in place. Interface 506 provides a structural connection between device 502 and cartridge 504 and can be established using suitable techniques, such as based on threads, latching mechanisms, bayonet fasteners, or magnetic couplings. In some implementations, interface 506 may also provide an electrical connection between device 502 and cartridge 504 using suitable electrical contacts. The electrical connection can allow the supply of electrical power and / or data to / from cartridge 504.

[0171] It should also be understood that in some implementations, the cartridge 504 can be refillable. That is, when the cartridge 504 is depleted, the aerosol generating material can be refilled into the cartridge 504 using a suitable mechanism, such as a one-way refill valve. The cartridge 504 can be removed from the device 502 for refilling. In other instances, the cartridge 504 can be configured to be refilled while attached to the device 502.

[0172] In the implementation of the aerosol supply system 501 as a one-piece or integrated system, the aerosol supply system 501 may be equipped with a suitable mechanism, such as a one-way valve, so as to refill the integrated cartridge 504 (or the integrated aerosol generating material storage area) with aerosol generating material.

[0173] exist Figure 6 In the middle, the cartridge part 504 includes a cartridge shell 542, an aerosol generating material storage area 544, an aerosol generator 548, an aerosol generating material transmission component 546, an outlet or opening 550, and an air path 552.

[0174] The cartridge housing 542 supports the other components of the cartridge 504 and provides a mechanical interface 506 for engagement with the device 502. The cartridge housing 542 is made of a suitable material, such as plastic or metal. In the described implementation, the cartridge housing 542 is generally circularly symmetrical about the longitudinal axis along which the cartridge 504 is attached to the device 502. In this example, the cartridge 504 has a length of approximately 4 cm and a diameter of approximately 1.5 cm. However, it should be understood that the specific geometry and, more generally, the overall shape may vary in different implementations. The cartridge 504 includes a first end generally defined by the interface 506 and a second end opposite the first end and including an opening 550. The second end including the opening is intended to be received in / by the user's mouth and may be referred to as the mouthpiece end of the cartridge 504.

[0175] An aerosol generating material storage area 544 is provided inside the cartridge casing 542, which can be referred to herein as a storage device 544. Figure 6 The cartridge 504 is configured to store a liquid aerosol generating material, which may be referred to herein as a source liquid, e-liquid, or liquid. The source liquid may contain nicotine and / or other active ingredients, and / or one or more flavoring agents, as described above. In some implementations, the source liquid may not contain nicotine. The reservoir 544 is suitably configured to hold or retain the liquid therein.

[0176] In this example, the reservoir 544 has an annular shape, its outer wall defined by the cartridge shell 542 and its inner wall defining an air path 552 through the cartridge 504. The reservoir 544 is closed at each end by an end wall to contain liquid. The reservoir 544 can be formed using suitable techniques; for example, the reservoir can comprise a plastic material and be integrally molded with the cartridge shell 542.

[0177] The cartridge 504 also includes an aerosol generator 548. The aerosol generator 548 is a device configured to generate an aerosol from an aerosol-generating material (e.g., a source liquid). The cartridge 504 also includes an aerosol-generating material transfer component 546 configured to transfer the aerosol-generating material from an aerosol-generating material storage area 544 (e.g., a reservoir 544) to the aerosol generator 548. In some implementations, the aerosol-generating material transfer component 546 may be integral with the aerosol generator 548 to form a combination of the aerosol generator 548 and the aerosol-generating material transfer component 546.

[0178] Aerosol generator 548 is configured to cause aerosol-generating material to generate aerosols. In some implementations, aerosol generator 548 is a heater 548. Heater 548 is configured to subject the aerosol-generating material to heat energy, causing the aerosol-generating material to release one or more volatiles to form an aerosol. For example, heater 548 may take the form of a resistance wire or resistance line designed to allow current to flow between the ends of the heater, or it may take the form of an inductive element designed to generate heat upon exposure to an alternating magnetic field. However, in other implementations, aerosol generator 548 is configured to cause the aerosol-generating material to generate aerosols without heating. For example, aerosol generator 548 may be configured to subject the aerosol-generating material to one or more of vibration, increased pressure, or electrostatic energy.

[0179] The aerosol generating material transport element 546 is configured to transport the aerosol generating material from the aerosol generating material storage area 544 (reservoir 544) to the aerosol generator 548. The properties of the aerosol generating material can determine the form of the aerosol generating material transport element 546. For example, for liquid or viscous gel aerosol generating materials, the aerosol generating material transport element 546 is configured to utilize capillary action to transport the liquid or viscous gel aerosol generating material. For example, the aerosol generating material transport element 546 may include porous materials (e.g., ceramics) or fiber bundles (e.g., glass or cotton fibers) capable of transporting liquid / viscous gels using capillary action.

[0180] exist Figure 6 In the described implementation, the aerosol generator 548 is a heater 548 in the form of a wire coil (such as a nickel-chromium alloy (Cr20Ni80) wire). Figure 6 In this implementation, the aerosol generating material transport element 546 is a core 546 in the form of a fiber bundle (such as glass fiber). Figure 6 As can be seen, heater 548 is wound around core 546 such that heater 548 is positioned close to core 546 and therefore also close to any liquid contained within core 546. In some implementations, aerosol generator 548 may include porous ceramic core 546 and conductive traces disposed on the surface of porous ceramic core serving as heater 548. In still other implementations, heater 548 and core 546 may be combined into a single component, for example, multiple sintered steel fibers forming a planar structure.

[0181] Heater 548 and core 546 are positioned towards the ends of reservoir 544. In this example, core 546 extends laterally across cartridge air path 552, with both ends extending into liquid reservoir 544 through openings in the inner wall of reservoir 544. The openings in the inner wall of reservoir are sized to approximately match the dimensions of core 546 to provide a reasonable seal against leakage from liquid reservoir 544 into cartridge air path 552 without overcompressing core 546, which could negatively impact fluid transfer performance. Therefore, core 546 is configured to transfer liquid from reservoir 544 to the vicinity of heater 548 via capillary effect.

[0182] The core 546 and heater 548 are arranged in the cartridge air path 552 such that the area surrounding the core 546 and heater 548 in the cartridge air path 552 effectively defines the atomization region of the cartridge 504. This atomization region (or aerosol generation region) is the area in the cartridge 504 where atomized gas is first generated and aerosol is first formed. In use, power can be supplied to the heater 548 to atomize a certain amount of liquid drawn through the core 546 to the vicinity of the heater 548.

[0183] The aerosol is delivered to the user via an outlet 550 located at the mouthpiece end of the cartridge 504. During use, the user can place their lips on or around the mouthpiece end of the cartridge 504 and inhale air / aerosol through the outlet 550. More specifically, air is drawn into the air path 552, then flows along the air path and passes through the aerosol generator 548, where the aerosol is entrained in the air, and the mixed aerosol / air is then inhaled by the user through the opening 550. Although Figure 6 The mouthpiece end of the cartridge 504 is shown as an integral part of the cartridge 504, but a separate mouthpiece component can be provided, which can be releasably attached to the end of the cartridge 504.

[0184] The device 502 includes an outer housing 512, an optional indicator 514, an intake sensor 516 located in a chamber 518, a controller or control circuit 520, a power source 526, an air inlet 528, and an air path 530.

[0185] Device component 502 includes: an outer housing 512 having an opening defining an air inlet 528 for the aerosol supply system 501; a power source 526 for providing operating power to the aerosol supply system 501; a controller or control circuit 520 for controlling and monitoring the operation of the aerosol supply system 501; and an inhalation sensor (suction detector) 516 located in a chamber 518. Device 502 also includes an optional indicator 514.

[0186] The outer housing 512 can be made of, for example, plastic or metal, and in this example, the outer housing has a circular cross-section, and its shape and size approximately match the shape and size of the cartridge 504 to achieve a smooth transition between the two components at the interface 506. In this example, the device 502 has a length of approximately 8 cm, so when the cartridge 504 and the device 502 are connected, the total length of the aerosol supply system 501 is approximately 12 cm. However, and as already noted, it should be understood that the overall shape and size of the aerosol supply system 501 of this disclosure are not essential to the principles described herein.

[0187] The outer housing 512 also includes an air inlet 528 connected to an air path 530 extending through the device 502. When the device 502 and the cartridge 504 are connected, the device air path 530 further connects to the cartridge air path 552 via an interface 506. In this regard, the interface 506 is also arranged to connect the respective air paths 530 and 552, allowing air and / or aerosol to flow along the connected air paths 530 and 552. In other implementations, the device 502 does not include an air path 530, but the cartridge 504 includes an air path 552 and a suitable air inlet that allows air to enter the air path 552 when the cartridge 504 and the device 502 are connected.

[0188] In this implementation, the power source 526 is a battery 526. The battery 526 is rechargeable and can be of a type commonly used in aerosol supply systems and other applications that require providing relatively high current over a relatively short period of time. The battery 526 can be, for example, a lithium-ion battery. The battery 526 can be recharged via a suitable charging connector (e.g., a USB connector) located at or within the outer housing 512. Alternatively or additionally, the device 502 may include suitable circuitry to facilitate wireless charging of the battery 526.

[0189] Control circuitry 520 is appropriately configured / programmed to control the operation of aerosol supply system 501. Control circuitry 520 can be considered to logically include various sub-units / circuit elements associated with different aspects of the operation of the aerosol supply system, and can be implemented by setting up a control chip of the form of a (micro)controller, processor, ASIC, or similar type. Control circuitry 520 can be arranged to control any function associated with system 501. By way of non-limiting examples only, in addition to functions such as controlling visual indicators (e.g., LEDs) / displays, communication functions for communicating with external devices, etc., this function may also include charging or recharging battery 526, discharging battery 526 (e.g., for providing power to heater 548). Control circuitry 520 can be mounted to a printed circuit board (PCB). It should also be noted that the functions provided by control circuitry 520 can be distributed across multiple circuit boards and / or distributed across components not mounted to a PCB, and these additional components and / or PCBs can be located within the aerosol supply device, as appropriate. For example, the function in control circuit 520 for controlling the (re)charging function of battery 526 can be set separately from the function for controlling the discharging function of battery 526 (e.g., set separately on different PCBs).

[0190] As noted above, when the device 502 and the cartridge 504 are connected together at the interface 506, the interface 506 provides an electrical connection between the device 502 and the cartridge 504. More specifically, the electrical contacts on the device 502 that connect to the power source 526 are electrically connected to the electrical contacts on the cartridge that connect to the heater 548. Therefore, under the proper control of the control circuit 520, power from the power source 526 can be supplied to the heater 548, thereby allowing the heater 548 to atomize the liquid held in the core 546 near the heater 548.

[0191] exist Figure 6 In one example, the aerosol supply device 502 includes a chamber 518 with a built-in inhalation sensor 516, which in this example is a pressure sensor 516. However, the inhalation sensor 516 can be any suitable sensor, such as an airflow sensor, used to sense when a user inhales at the mouthpiece end of the cartridge 504 and air subsequently flows along air paths 530, 552. Therefore, the presence of the chamber 518 is optional, and the presence of the chamber can depend on the characteristics of the selected inhalation sensor 516.

[0192] Pressure sensor 516 is in fluid communication with air path 530 in device 502 (e.g., chamber 518 branches off from air path 530 in device 502). Therefore, when a user inhales through opening 550, a pressure drop occurs in chamber 518, which can be detected by pressure sensor 516 if the pressure drop is large enough. In response to detecting user inhalation, aerosol supply system 501 is controlled to generate aerosol. That is, when pressure sensor 516 detects a pressure drop in pressure sensor chamber 518, control circuitry 520 responds by supplying sufficient power from battery 526 to aerosol generator 548, thereby atomizing the liquid held within core 546. This is an example of an aerosol supply system known as "suction-actuated". Pressure sensor 516 can be used to start and / or stop power supply to heater 548 (e.g., when pressure sensor detects no inhalation).

[0193] In other implementations, the aerosol supply system 501 includes a button or other user-actuable mechanism. When the button or other user-actuable mechanism is actuated by a user, the control circuit 520 supplies electrical energy to the heater 548, as described above. This is an example of an aerosol supply system referred to as "button-actuated." The button can be used to start and / or stop power supply to the heater 548 (e.g., when the user releases the button). In some implementations, both the button (or other user-actuable mechanism) and the inhalation sensor 516 can be used simultaneously to control the supply of electrical energy to the heater 548, for example, requiring both button pressing and pressure drop (indicating the presence of inhalation) to occur simultaneously before power is supplied to the heater 548.

[0194] As mentioned above, the power source 526 in the aerosol supply device 502 is a rechargeable battery 526. Since the aerosol supply device 502 is designed for use with multiple cartridges (or multiple refills of the integrally formed reservoir 544), by providing a rechargeable battery 526, the lifespan of the aerosol supply device 502 can be extended, allowing it to be used with more cartridges 504 compared to using a non-rechargeable battery of similar size or capacity. Alternatively, due to the fact that the battery 526 is rechargeable, its physical size can be reduced, resulting in a smaller aerosol supply device 502 without compromising the overall lifespan of the aerosol supply system 501.

[0195] However, the maximum potential capacity of a rechargeable power source 526 (e.g., a lithium-ion battery) tends to decrease with increasing number of recharge cycles. That is, for example, a lithium-ion battery with a maximum potential capacity of 500 mAh after one recharge cycle may experience a capacity decrease of 50 mAh after, say, 100 recharge cycles. Other factors such as ambient temperature or the way the battery is discharged during use may also affect the rate of capacity decay of lithium-ion batteries. Therefore, users of an aerosol supply system 501 with rechargeable batteries often perceive a decrease in battery capacity over time (which can be perceived by the user due to the need for more frequent recharging of the aerosol supply system).

[0196] For most users, the aerosol supply system 501 is used to supply nicotine (or other active substances) to the user, and therefore, during the time of day when the user cannot recharge the battery 526, the user will worry about insufficient power in the battery 526, which may cause some users to feel anxious or even cause the user to consider alternative means of delivering nicotine (or other active substances).

[0197] Therefore, according to this disclosure, the aerosol supply system 501 is provided with a power source measurement circuit 524 configured to measure or determine the current maximum potential capacity of the power source 526. The output of the power source measurement circuit 524 is provided to a control circuit 520 (or to a specific part / module / circuit of the control circuit 520), wherein the control circuit 520 is configured to determine the effective capacity of the power source by comparing a (pre-acquired) default maximum potential capacity with the current maximum potential capacity of the power source. Based on the determined effective capacity of the power source 526, the control circuit 520 or the aerosol supply system 501 can perform one or more actions.

[0198] Power source measurement circuit 524 in Figure 6 The image is schematically shown as being positioned between the control circuit 520 and the power source 526, and more specifically, on the wires / connectors connecting the power source 526 and the control circuit 520. Figure 6 In the aerosol supply system 501, the power source measurement circuit 524 is shown as a separate circuit / module; however, it should be understood that in some implementations, the power source measurement circuit 524 may be integrated with the control circuit 520.

[0199] The power source measurement circuit 524 is adapted to perform electrical measurements associated with the power source 526, such as voltage and / or current, but other measurements may be performed in other implementations. In some implementations, the power source measurement circuit 524 or control circuit 520 may be equipped with a timer or clock, which can be used to trigger the measurement or record the corresponding time point during the measurement. In some other implementations, the power source measurement circuit 524 or control circuit 520 may be equipped with a mechanism for detecting when the power source 526 begins recharging.

[0200] Figure 7 An exemplary method for determining the effective capacity of the power source 526 of the aerosol supply system 501 according to various aspects of this disclosure is shown.

[0201] exist Figure 7In this method, the process begins at step S11, in which control circuitry 520 acquires the default maximum potential capacity of power source 526. In some implementations, the default maximum potential capacity of power source 526 may be pre-programmed into control circuitry 520 during the manufacture of aerosol supply system 501. For example, power source 526 used with aerosol supply system 501 may be accompanied by an indication of maximum potential capacity, and this value may be programmed into control circuitry 520. In other implementations, control circuitry 520 may be configured to identify power source 526 (e.g., from a readable chip mounted on power source 526) when power source 526 is installed in aerosol supply system 501 and transmit the acquired identifier, for example via wireless communication, to a remote server to obtain an indication of maximum potential capacity. In some other implementations, the power source measurement circuit 524 may be configured to perform one or more measurements and determine the default maximum potential capacity of the power source 526 when the power source 526 is initially installed in the aerosol supply device 502 (note that at least initially, the attenuation of the power source 526 may be minimal).

[0202] Following step S11, the method proceeds to step S12, in which the power source measurement circuit 524 is configured to determine the current maximum potential capacity of the power source 526. Step S11 is typically performed long before step S12, for example, during the manufacturing phase, while step S12 is typically performed when the user has the aerosol supply system 501 and has been using the device 502. Step S12 may be performed periodically after the aerosol supply system 501 is first started (e.g., after the inhalation sensor 516 first detects a user inhalation). For example, step S12 may be performed every 524 hours or 548 hours after initial use, but it should be understood that this time period may be set based on the expected rate of decay of the power source 526. Alternatively or additionally, step S12 may be performed periodically more frequently than described above after another criterion (such as the number of charging cycles reaching a predetermined threshold, or the use of the device 502 reaching a specific threshold) has been met. In other implementations, step S12 may be performed after each use, or after multiple uses, and / or each time device 502 is powered on.

[0203] As noted above, the power source measurement circuit 524 is configured to measure or determine the current maximum potential capacity of the power source 526. It should be understood that during use, such as due to self-discharge or controlled discharge (e.g., when powering the aerosol generator 548) or incomplete recharge cycles, the available energy of the power source 526 at any given time may not equal its maximum potential capacity. Therefore, based on one or more measurements performed, the power source measurement circuit 524 can determine the current maximum potential capacity of the power source 526.

[0204] The power source measurement circuit 524 can be adapted to use any suitable technique to determine the maximum potential capacity of the power source 526. However, by way of example, we consider the following two techniques that can determine the maximum potential capacity.

[0205] Figure 8 An exemplary graph is shown, representing the change in the capacity of power source 526 (expressed in arbitrary units on the y-axis) over time (expressed in arbitrary units on the x-axis) during a recharging operation. In this example, power source 526 begins recharging from its initial value at time point t1. Two scenarios are shown: curve A shows an exemplary measured capacity of power source 526 during recharging with almost no capacity decay, while curve B shows an exemplary measured capacity of power source 526 during recharging with some capacity decay.

[0206] According to the first implementation, the power source measurement circuit 524 is configured to measure the current maximum potential capacity of the power source 526 after a recharge cycle of a predetermined duration and / or current has been performed. That is, in this implementation, the power source measurement circuit 524 determines the current maximum potential capacity of the power source 526 from the recharge initiation point (e.g., ...). Figure 8 The system determines whether a predetermined duration d has elapsed at time point t1, and is subsequently configured to perform a measurement at time point t2. For example, the power source measurement circuit 524 can measure the voltage of the power source 526 at time point t2.

[0207] like Figure 8 As can be seen, the relative capacities of the two power sources 526 represented by curves A and B are different at time point t2. Based on the measurement results obtained at time point t2, the capacities of these two power sources 526 can be determined.

[0208] In some implementations, the duration d can be set to an appropriate duration. For example, the duration d can be preset to the time period during which a depleted battery is expected to be fully charged (or charged to a certain amount, e.g., 95% of its full capacity), such that the measurement at time point t2 is considered to indicate that the battery is fully charged or nearly fully charged, thus better representing the maximum potential capacity of the power source 526. In some cases, the power source may not be charged throughout the entire duration, and in this case, the power source measurement circuit 524 can be configured to abandon the determination of the current maximum potential capacity.

[0209] Figure 9Similarly, an exemplary graph is shown to represent the change in the capacity of power source 526 (expressed in arbitrary units on the y-axis) over time (expressed in arbitrary units on the x-axis) during a recharging operation. In this example, power source 526 begins recharging from its initial value at time t1. Two scenarios are shown: curve A shows an exemplary measured capacity of power source 526 during recharging with almost no capacity decay, while curve B shows an exemplary measured capacity of power source 526 during recharging with some capacity decay.

[0210] According to the second implementation, the power source measurement circuit 524 is configured to measure the current maximum potential capacity of the power source 526 by monitoring the output voltage of the power source 526 during a recharge cycle and determining when the rate of change of the output voltage over time is lower than a predetermined value.

[0211] For example, refer to Figure 9 The dashed lines tangent to curves A and B represent the specific slopes of curves A and B as they change over time. In this example, this slope actually represents the rate of change of the measured voltage over time. Although the actual capacity of the power sources differs at time point t3 due to the decay mentioned above, the charging curves are similar in form / shape. Therefore, by identifying when the rate of change of the output voltage over time reaches a threshold, this can indicate the commonalities of the two power sources 526 in the recharge cycle. That is, when the rate of change of voltage over time is, for example, XV / s, this may indicate that the power source has reached, for example, Y% of its maximum potential current capacity. Therefore, a comparison between the default maximum potential capacity and the current maximum potential capacity can be achieved.

[0212] In this implementation, it should be recognized that the measurement performed at t3 is not like that at... Figure 8 The timing is fixed relative to the start of charging, and therefore less dependent on identifying the start time of recharging. Furthermore, measurements can be performed more quickly because it depends on whether the desired rate of voltage change is reached, rather than after a fixed duration, in which case the recharge cycle would actually take longer than required in practice.

[0213] Figure 8 and Figure 9 The two examples above should be understood as merely examples, and those skilled in the art will know and be able to implement other techniques that can be used to determine the current maximum potential capacity of power source 526. That is, the specific manner in which power source measurement circuit 524 is configured to measure the current maximum potential capacity is not important to the principles of this disclosure.

[0214] Return to reference Figure 7In step S13, the control circuit 520 is configured to determine the effective capacity after receiving the output of the current maximum potential capacity from the power source measurement circuit 524. The effective capacity indicates the degradation of the power source 526. For example, if the default maximum potential capacity is 500 mAh, representing the theoretical 100% capacity of the power source 526, the determined current maximum potential capacity could be, for example, 450 mAh. In this respect, the effective capacity can be determined as a percentage of the determined current maximum potential capacity relative to the default maximum potential capacity; for example, in the above example, the effective capacity could be 90%. Therefore, the effective capacity indicates that the capacity of the power source 526 has degraded by 10%. The effective capacity is not limited to a percentage measurement; for example, in other implementations, the effective capacity could be the absolute value of the difference between the default maximum potential capacity and the determined current maximum potential capacity, or in other implementations, the effective capacity could be the same as the determined current maximum potential capacity.

[0215] In step S13, the control circuit 520 is configured to determine whether the effective capacity is below a threshold. This threshold can be appropriately set according to the form of the effective capacity. For example, if the effective capacity is determined as a percentage, the threshold can be set to, for example, 70%. Therefore, the control circuit 520 is configured to compare the effective capacity with the threshold and determine whether the effective capacity is below the threshold.

[0216] If the effective capacity is not lower than the threshold at step S13 (i.e., no at step S13), the method returns to step S12 and determines the current maximum potential capacity again (i.e., as described above, later).

[0217] Conversely, if the effective capacity is below the threshold at step S13 (i.e., yes at step S13), the method proceeds to one or more of steps S14, S15, and S16.

[0218] At step S14, control circuitry 520 is configured to trigger an alarm to the user of aerosol supply system 501. This alarm can take any form and be delivered to the user in any suitable manner. For example, indicator 514 of aerosol supply system 501 may include a display, LED, or other visual element actuated to provide an alarm to the user (e.g., as an image / message displayed on the display, or via flashing or illuminating LEDs). Alternatively or additionally, indicator 514 may include a speaker, and the alarm may include sound generated by the speaker, which may include recorded voice messages, etc. Also alternatively or additionally, indicator 514 may include a haptic motor configured to generate haptic feedback to provide the alarm to the user.

[0219] Regardless of the form and mechanism of the alarm, it serves to indicate to the user that the effective capacity is below a threshold, suggesting that power source 526 has degraded beyond acceptable levels (and therefore, the user may face a greater risk of power depletion and inability to power aerosol supply system 501). In some implementations, the alarm includes a message informing the user that power source 526 of aerosol supply system 501 should be replaced. In some implementations, power source 526 can be removed from aerosol supply unit 502, and a new power source 526 can be installed in place. In other implementations, power source 526 can be integrally formed with aerosol supply unit 502, and therefore replacement of power source 526 can be achieved by replacing aerosol supply unit 502. Depending on the form of the alarm, the message informing the user that power source 526 of aerosol supply system 501 should be replaced can take any suitable form (e.g., a text message on a display, a voice message played by a speaker, or a series of flashes / vibrations, etc.). Similar to the form of the alarm, there are no particular restrictions on the form of the message, and it can take any suitable form.

[0220] In addition to providing an alarm at step S14, or as an alternative, at step S15, control circuitry 520 may, in response to determining that the effective capacity is below a threshold, feed back the determined effective capacity to the user. While an alarm at step S14 can notify the user that the effective capacity is below the threshold, in some implementations it may be necessary to provide the user with an indication of the effective capacity to help accurately inform the user of the extent to which the effective capacity is below the threshold. This can help guide and inform the user about their continued use of the aerosol supply system 501 and / or the urgency of replacing the power source 526. In a similar manner, the effective capacity of the power source 526 can take the form of a suitable message (e.g., a text message on a display, a voice message played by a speaker, or a series of flashes / vibrations, etc.). There are no particular limitations on the way the effective capacity is conveyed to the user and it can take any suitable form.

[0221] In addition to providing an alarm at step S14 and / or providing the determined effective capacity at step S15, or as an alternative, at step S16, the control circuit 520 is further configured to determine the effective usage in response to determining that the effective capacity is below a threshold. The effective usage count represents the approximate number of inhalations that the power source 526 can achieve, and is determined based on the determined effective capacity and pre-acquired user usage behavior. That is, the control circuit 520 is able to determine the approximate number of inhalations that the power source 526 can achieve at its current maximum potential capacity, allowing the user to know that the expected usage of the power source 526 when it is charged to its maximum usable capacity is X inhalations, and thus the user can plan whether this is sufficient for their use throughout the day (or more specifically, between recharge cycles).

[0222] In one implementation, for a given aerosol supply system 501, user behavior is predetermined and fixed. For example, the manufacturer of the aerosol supply system 501 may determine that the average inhalation is approximately two seconds and that each inhalation consumes approximately 1.2 mAh of power. Therefore, a power source 526 with a determined current maximum potential capacity of 450 mAh can provide approximately 540 inhalations (compared to a power source with a capacity of 500 mAh capable of providing 600 inhalations).

[0223] In other implementations, control circuitry 520 is configured to determine the average power consumption based on data corresponding to the user. For example, control circuitry 520 may be configured to determine the duration of a user's inhalation, for example, by determining the duration between the start and end of an inhalation detected by inhalation sensor 516 over multiple inhalations. In other implementations, control circuitry 520 may also be configured to determine the average power applied to aerosol generator 548 (e.g., by measuring or otherwise knowing the voltage and / or current supplied to aerosol generator 548), and determine the average power consumption of the given user during each inhalation based on the average duration and optionally the average power. In this way, user behavior can be tailored to the specific user to better determine the approximate number of inhalations achievable with a fully charged power source 526 based on the determined current maximum potential capacity of the power source 526.

[0224] Therefore, in step S16, the control circuit 520 is configured to determine the effective number of uses and transmit it to the user, so that the user can determine whether the current state of the power source 526 is suitable for their daily use (or between two recharge cycles).

[0225] In some implementations, Figure 7 The method does not include any steps related to the control of the aerosol generator 548. Typically, for certain power sources (such as lithium-ion batteries), discharge should not continue when the charge of the power source 526 drops below a safe operating limit. The alarm in step S14, the effective capacity feedback in step S15, and the transmission of the effective usage count in step S16 are typically provided independently of the actual charge of the power source 526 dropping below the safe operating limit, because this information relates to parameters associated with the current maximum potential capacity of the power source 526 (i.e., not the actually measured charge). However, in some implementations, the control circuit 520 may be configured to prevent the aerosol generator 548 from being activated, for example, when the determined current maximum potential capacity approaches the safe operating limit.

[0226] While any of steps S14 through S16 is being performed, alarms / feedback / information can be continuously provided to the user until the user replaces the power source 526 or the aerosol supply device 502. In other implementations, the aerosol supply system 501 may be equipped with a temporary mute button, which allows the alarms / feedback / information of steps S14, S15, and S16 to be temporarily muted, for example, for a predetermined period of time. After the predetermined period of time has elapsed, alarms / feedback / information can be provided to the user again.

[0227] exist Figure 7 In the exemplary method, the effective capacity is compared with a single threshold at step S13. However, it should be understood that the method can be extended to compare the effective capacity with multiple thresholds at different levels. For example, the effective capacity can be compared with, say, a threshold of 80%, and if the effective capacity is below this level, the method first executes any one of steps S14 to S16. For example, an alarm can be generated using the text message “POWER SOURCENEEDS REPLACING SOON”. The effective capacity can be compared with a second threshold of, say, 60%, and if the effective capacity is below this level, the method again executes any one of steps S14 to S16. For example, in this second example, an alarm can be generated using the text message “POWER SOURCE NEEDS REPLACING NOW”.

[0228] If the effective capacity is not lower than the threshold at step S13 (i.e., no at step S13), in some implementations, the aerosol supply system 501 can be configured to provide a notification to the user indicating that the power source 526 is in good condition. For example, the aerosol supply system 501 can be configured to use any of the above-mentioned feedback mechanisms (e.g., display, LED, acoustic speaker, haptic motor, etc.) to trigger the generation of a notification indicating that the power source 526 is normal or in good condition.

[0229] As described above, in some implementations, the alarm in step S14, the effective capacity feedback in step S15, and the communication of the effective number of uses in step S16 are all provided on the relevant feedback mechanism of the aerosol supply system 501 / device 502. Figure 10 An aerosol supply system 501 (such as...) is schematically shown. Figure 6 The aerosol supply system 501 has a display 514 on the housing 512 of the aerosol supply device 502.

[0230] However, in other implementations, the aerosol supply system 501 may be equipped with suitable circuitry to connect to a remote device 600, such as a smartphone, laptop, smartwatch or other wearable technology, or personal digital assistant. Figure 11 An aerosol supply system 501 (such as...) is schematically shown. Figure 6 An exemplary arrangement of the aerosol supply system 501 is configured to wirelessly communicate with a remote device 600 (e.g., a smartphone in this example). In this example, the aerosol supply system 501 may not have any suitable feedback mechanism for providing an alarm for step S14, effective capacity feedback for step S15, and effective usage count communication at step S16. Instead, it may be configured to send signals to the remote device 600 to use the feedback mechanism of the remote device 600 (such as a display 601) to provide an alarm for step S14, effective capacity feedback for step S15, and / or effective usage count communication at step S16.

[0231] In principle, it should be understood that each of the alarm in step S14, the effective capacity feedback in step S15, and the communication of the effective number of uses in step S16 can be set individually on either or both of the aerosol supply system 501 or the remote device 600, depending on the specific implementation.

[0232] Therefore, according to the principles of this disclosure, the aerosol supply system 501 is configured to determine the effective capacity of the power source 526 based on the output from the power source measurement circuit 524, which is the current maximum potential capacity of the power source 526 and the pre-acquired default maximum potential capacity of the power source 526. The effective capacity of the power source 526 represents the capacity decay of the power source 526 over time. The aerosol supply system 501 can perform actions based on the effective capacity, which can guide the user to take subsequent actions regarding the use of the aerosol supply system 501 (such as replacing the power source 526, and / or planning their use of the aerosol supply system 501). In this way, the user can know when the power source 526 is no longer suitable for use and should be replaced. This can help alleviate some of the anxiety experienced by the user when using the aerosol supply system 501 for extended periods between charging cycles.

[0233] Based on the principles of this disclosure, an aerosol supply component (including an aerosol supply system 501) for generating aerosols from an aerosol-generating material is also provided. The aerosol supply component includes: a power supply component including a power source 526; a control component including control circuitry 520; an aerosol generating component including an aerosol generator 548 for generating aerosols from the aerosol-generating material when power is supplied by the power supply component under the control of the control component; and a power source measuring component including power source measuring circuitry 524 configured to measure the current maximum potential capacity of the power supply component. The control component is configured to determine the effective capacity of the power supply component by comparing a pre-acquired default maximum potential capacity with the current maximum potential capacity of the power supply component.

[0234] Therefore, an aerosol supply system for generating aerosols from an aerosol-generating material has been described, the aerosol supply system comprising: a power source; a control circuit; an aerosol generator for generating aerosols from the aerosol-generating material when power is supplied by the power source under the control of the control circuit; and a power source measurement circuit configured to measure the current maximum potential capacity of the power source.

In other words, the specific manner in which various aspects of the aerosol supply system function are not directly related to the basic principles of the examples described herein.
