Description

Technical Field

[0001] This disclosure relates to aerosol delivery systems that may include nicotine delivery systems and subsystems (such as cartridges) used in conjunction with a wider range of aerosol delivery systems. Background Technology

[0002] Aerosol delivery systems, such as those for electronic cigarettes (e-cigarettes), generally include aerosol-generating materials, such as chambers containing source solids or liquids that may contain active substances and / or flavorings. Aerosols or vapors are generated from these materials, for example, through thermal evaporation, for inhalation by a user. Aerosol delivery systems typically include an aerosol-generating region containing an aerosol generator (e.g., a heating element) arranged to evaporate or aerosolize a portion of the precursor material to generate vapor or aerosol in the aerosol-generating region. When a user inhales through the system and electricity is supplied to the vaporizer, air is drawn into the system through an inlet orifice and along an air inlet channel connected to the aerosol-generating region, where it mixes with the evaporated precursor material to form a condensed aerosol. An outlet channel connects the aerosol-generating region to an outlet in the mouthpiece, and the air drawn into the aerosol-generating region when the user inhales through the mouthpiece continues along the outlet flow path to the mouthpiece outlet, carrying the aerosol for inhalation by the user.

[0003] Some electronic cigarettes may include flavoring elements in the airflow path to impart additional flavor. Such a system may be referred to as a mixing device, and the flavoring element may, for example, include a portion of tobacco arranged in the airflow path between the aerosol generation area and the mouthpiece, such that the vapor / aerosol inhaled through the device passes through the portion of tobacco before leaving the mouthpiece for the user to inhale.

[0058] This document describes aspects and features of certain examples and implementations. Some aspects and features can be conventionally implemented, and for the sake of brevity, these aspects and features are not described in detail.

[0059] The claimed invention generally provides a sub-component or subsystem suitable for use in or configured for use in an aerosol delivery system. The subsystem generally forms part of the aerosol delivery system, and specifically forms part of a reusable device and / or consumable cartridge in a two-piece system.

[0060] introduce

[0061] Figure 1 This is a cross-sectional view through an exemplary aerosol delivery system 1 according to certain embodiments of the present disclosure, providing an introduction to a two-piece aerosol delivery system, its components, and their functions.

[0062] The aerosol delivery system 1 comprises two main parts: a reusable part 2 (sometimes referred to as a control unit) and a replaceable / disposable consumable cartridge part 4 (sometimes referred to as a consumable or product). During normal use, the reusable part 2 and the cartridge part 4 are releasably connected together at an interface 6. When the cartridge part 4 is depleted or the user wishes to switch to a different cartridge part 4, the cartridge part 4 can be removed from the reusable part 2, and a replacement cartridge part 4 can be attached to the reusable part 2 in its proper position. The interface 6 provides structural, electrical, and airflow path connections between the two parts 2 and 4, and can be established according to conventional techniques, such as threaded, magnetic, or bayonet fastening using electrical contacts and openings for proper electrical connections and airflow paths between the two parts 2 and 4. The specific manner in which the cartridge part 4 is mounted to the reusable part 2 is not critical to the principles described herein, but for the sake of concrete example, it is assumed here that a magnetic connection is included. Figure 1(Not shown in the image). It will also be understood that in some implementations, interface 6 may not support electrical connections and / or airflow path connections between the corresponding parts 2 and 4. For example, in some implementations, the aerosol generator may be located in the reusable part 2 instead of the cartridge part 4, or the electrical power transfer from the reusable part 2 to the cartridge part 4 may be wireless (e.g., based on electromagnetic induction), thus eliminating the need for an electrical connection between the reusable part 2 and the cartridge part 4. Furthermore, in some implementations, the airflow through system 1 may not pass through the reusable part 2, thus eliminating the need for an airflow path connection between the reusable part 2 and the cartridge part 4. In some cases, when the reusable part 2 and the cartridge part 4 are used together, a portion of the airflow path may be limited at the interface between the reusable part and the cartridge part.

[0063] In some implementations, the cartridge / consumable portion 4 can be largely conventional. Figure 1 In this design, the cartridge portion 4 includes a cartridge shell 42 formed of plastic material. The cartridge shell 42 supports other components of the cartridge portion 4 and provides a mechanical interface 6 with the reusable portion 2. The cartridge shell 42 is generally circularly symmetrical about a longitudinal axis along which the cartridge portion 4 is connected to the reusable portion 2. In this example, the cartridge portion 4 has a length of approximately 4 cm and a diameter of approximately 1.5 cm. However, the specific dimensions, geometry, overall shape, and materials used can vary.

[0064] A chamber or reservoir 44 is located within the cartridge casing 42 and contains aerosol-generating materials. Figure 1 In this example, the reservoir 44 stores a supply of liquid aerosol generating material, and the liquid reservoir 44 has an annular shape having an outer wall defined by the cartridge shell 42 and an inner wall defining an airflow path 52 through the cartridge portion 4. The reservoir 44 is closed at each end with an end wall to accommodate the aerosol generating material. The reservoir 44 can be conventionally formed, for example, comprising a plastic material and / or integrally molded with the cartridge shell 42.

[0065] The cartridge / consumable section 4 also includes an aerosol generator 48, which in this example is positioned toward the end of the reservoir 44 opposite the mouthpiece outlet 50. In, for example... Figure 1In the two-piece system, the aerosol generator 48 can be located in either the reusable portion 2 or the cartridge portion 4. For example, in some embodiments, the aerosol generator 48 (e.g., a heater, which may be in the form of a core and coil arrangement as shown, a distiller, which may be formed of sintered metal fiber material or other porous conductive material, or any suitable alternative aerosol generator) may be included in the reusable portion 2 and is close to a portion of the aerosol-generating material in the cartridge portion 4 when the cartridge portion 4 is engaged with the reusable portion 2. In such embodiments, the cartridge portion 4 may include a portion of the aerosol-generating material, and when the cartridge portion 4 is engaged with the reusable portion 2, the aerosol generator 48 is at least partially inserted into or at least partially surrounding that portion of the aerosol-generating material.

[0066] exist Figure 1 In this example, the core 46, which is in contact with the aerosol generator 48, extends laterally across the cartridge airflow path 52, with its end extending through an opening in the inner wall into a reservoir 44 for liquid aerosol generating material. The opening in the inner wall of the reservoir 44 is sized to substantially match the size of the core 46 to provide a reasonable seal that prevents leakage from the reservoir 44 into the cartridge airflow path 52 without over-compressing the core 46 (which could be detrimental to its fluid delivery performance).

[0067] The wick 46 and aerosol generator 48 are arranged in the cartridge airflow path 52 such that the area of ​​the cartridge airflow path 52 surrounding the wick 46 and heater 48 effectively defines the evaporation area of ​​the cartridge portion 4. Aerosol-generating material in the reservoir 44 permeates into the wick 46 through the end of the wick extending into the reservoir 44 and is drawn along the wick by surface tension / capillary action (i.e., wicking). In this example, the aerosol generator 48 comprises a resistance wire wound around the wick 46. Figure 1 In this design, the aerosol generator 48 comprises a nickel-chromium alloy (Cr20Ni80) wire, and the core 46 comprises a glass fiber bundle; however, the specific aerosol generator configuration is not critical to the described principle. In use, electricity can be supplied to the aerosol generator 48 to cause a certain amount of aerosol-generating material drawn into the vicinity of the aerosol generator 48 via the core 46 to evaporate. The evaporated aerosol-generating material can then be entrained in the air drawn from the evaporation area toward the mouthpiece outlet 50 along the cartridge's airflow path for the user to inhale.

[0068] As described above, the rate at which the aerosol-generating material is evaporated by the aerosol generator 48 will depend on the amount (level) of power supplied to the aerosol generator 48. Therefore, electrical power can be applied to the aerosol generator 48 to selectively generate aerosols from the aerosol-generating material in the cartridge portion 4, and furthermore, the aerosol generation rate can be changed by, for example, by altering the amount of power supplied to the aerosol generator 48 through pulse width and / or frequency modulation techniques.

[0069] The reusable part 2 includes: a housing 12 having an opening defining an air inlet 28 for the system 1; a power source 26 (e.g., a battery) for providing operating power to the system 1; a control circuit / controller 22 for controlling and monitoring the operation of the system 1; a first user input button 14; a second user input button 16; and a visual display 24. The housing 12 may be formed, for example, of a plastic or metal material, and in this example has a circular cross-section that generally conforms to the shape and size of the cartridge part 4 to provide a smooth transition between the two parts 2 and 4 at the interface 6. In this example, the reusable part 2 has a length of approximately 8 cm, so when the cartridge part 4 and the reusable part 2 are joined together, the total length of the system 1 is approximately 12 cm. However, the specific dimensions, geometry, overall shape, and materials used can vary.

[0070] In this embodiment, as further discussed below with reference to the accompanying drawings, system 1 includes at least a portion having a high light absorption coefficient. Specifically, one or more reusable device housings 12, cartridge housings 42, and / or storage units 44 may include high light absorption portions.

[0071] Air inlet 28 is connected to airflow path 51 via reusable portion 2. When reusable portion 2 and cartridge portion 4 are connected together, reusable portion airflow path 51 is connected to cartridge airflow path 52 across interface 6. Therefore, when a user inhales through mouthpiece opening 50, air is drawn in through air inlet 28, along reusable portion airflow path 51, across interface 6, through aerosol generation area near aerosol generator 48 (where evaporated aerosol generation material is entrained in the airflow), along cartridge airflow path 52, and discharged through mouthpiece opening 50 for the user to inhale.

[0072] The power source 26 in this example is rechargeable and can be of a conventional type, such as those commonly used in electronic cigarettes and other applications requiring a relatively high current supply for a relatively short period. The power source 26 can be recharged via a charging connector (e.g., a USB connector) within the reusable housing 12.

[0073] Optionally, a first user input button 14 and / or a second user input button 16 may be provided. In this example, the user input button is a conventional mechanical button, such as including a spring-loaded component that can be pressed by a user to establish electrical contact. The input button may be an input device for detecting user input, and the manner in which the button is implemented is not important. The button may be assigned functions such as turning system 1 on and off and / or adjusting user settings (such as the power supplied from power source 26 to aerosol generator 48).

[0074] A display 24 may be provided to offer a user visual indications of various characteristics associated with the aerosol delivery system, such as current power settings, remaining power, etc. This display can be implemented in various ways. In this example, display 24 includes a conventional pixelated LCD screen. In other implementations, the display may include one or more discrete indicators, such as LEDs, arranged to display information, for example, through a specific color and / or flashing sequence. More generally, the provision of display 24 and the manner in which the information is displayed are not critical to the principles described herein—other embodiments may not include a visual display and / or may include other means for providing a user with information related to the operational characteristics of system 1, for example, using audio signaling.

[0075] Controller 22 is suitably configured / programmed to control aerosol delivery system 1 to provide the functions described herein, as well as general operational functions for system 1. Controller (processor circuitry) 22 can be considered to logically include various sub-units / circuit elements associated with different aspects of the operation of system 1. In this example, controller 22 includes power control circuitry for controlling the power supply from power source 26 to aerosol generator 48 in response to user input, user programming circuitry 20 for establishing configuration settings (e.g., user-defined power settings) in response to user input, and other functional units / circuits associated with the principles and general operational aspects described herein (such as display driver circuitry and user input detection circuitry). The functionality of controller 22 can be provided in various ways, such as using one or more programmed programmable computers and / or one or more suitably configured application-specific integrated circuits / circuits / chips / chipsets. Controller 22 may include an application-specific integrated circuit (ASIC), CPU, microprocessor, or microcontroller. The operation of the controller and other electronic components is generally controlled by software / instructions running on the controller. This software / instructions can be stored in non-volatile memory (e.g., ROM), which can be integrated into the controller or provided separately. The controller 22 can access the ROM to load and execute the various software components as needed and as required.

[0076] The reusable portion 2 includes an airflow sensor 30 electrically connected to the controller 22. In most embodiments, the airflow sensor 30 includes a so-called "inhalation sensor" because it is used to detect when a user inhales on the system 1. In some embodiments, the airflow sensor 30 includes a switch located in the electrical path supplying electrical power from the power source 26 to the aerosol generator 48. In such embodiments, the airflow sensor 30 generally includes a pressure sensor configured to close the switch when subjected to a specific range of pressure, such that current can flow from the power source 26 to the aerosol generator 48 once the pressure near the airflow sensor 30 drops below a threshold. The threshold can be set to a value determined experimentally to correspond to a characteristic value associated with the start of a user's inhalation. In other embodiments, the airflow sensor 30 is connected to the controller 22, and the controller 22 distributes electrical power from the power source 26 to the aerosol generator 48 based on signals received by the controller 22 from the airflow sensor 30. The controller 22 uses the signal output from the airflow sensor 30 (which may include measurements of the capacitance, resistance or other characteristics of the airflow sensor generated by the controller 22) to control the power supply from the power source 26 to the aerosol generator 48 in any manner known to those skilled in the art.

[0077] exist Figure 1 In the example shown, the airflow sensor 30 is mounted to an optional printed circuit board (PCB). The airflow sensor 30 may include any sensor configured to determine the characteristics of airflow in an airflow path 51 disposed between the air inlet 28 and the mouthpiece opening 50, such as a pressure sensor or transducer (e.g., a diaphragm or solid-state pressure sensor), a combined temperature and pressure sensor, or a microphone (e.g., an electret microphone) sensitive to changes in air pressure, including acoustic signals. The airflow sensor 30 is located within a sensor cavity or chamber 32, which includes an internal space defined by one or more chamber walls. The sensor cavity 32 includes a region within one or more chamber walls in which the airflow sensor 30 may be located wholly or partially. In some embodiments, the PCB includes one of the chamber walls of the sensor housing (including the sensor cavity / cavity 32).

[0078] The deformable membrane can span an opening that connects the sensor cavity 32 housing the sensor 30 to the portion of the airflow path disposed between the air inlet 28 and the nozzle opening 50. According to the method further described herein, the deformable membrane covers the opening and is attached to one or more of the cavity walls.

[0079] The aerosol delivery system 1 may include communication circuitry configured to connect to one or more additional electronic devices (e.g., storage / charging enclosures, or refill / charging docks) to enable data transfer between the system 1 and the additional electronic devices. The communication circuitry may be integrated into the controller 22 or implemented separately. The communication circuitry may be configured to support wired or wireless communication between the aerosol delivery system 1 and the additional electronic devices, such as enclosures, docks, computing devices (e.g., smartphones or PCs), cellular-enabled base stations, relay nodes providing connectivity to base stations, wearable devices, or any other portable or fixed devices. The controller 22, other components within the system 1, and other devices / systems may include one or more processors, and data processing may be performed on any of these processors or on a remote processor, with data transmitted via wires or wirelessly.

[0080] Wireless communication between the aerosol delivery system 1 and other electronic devices can be configured according to a data transmission protocol, such as... ZigBee Wifi Direct, GSM, 2G, 3G, 4G, 5G, LTE, NFC, RFID, or generally any other wireless and / or wired network protocol or interface. The communication circuitry may include any suitable interface for wired data connectivity, such as USB-C, micro USB, or Thunderbolt interfaces, and may include pin or contact pad arrangements configured to engage cooperating pins or contact pads on docking stations, chassis, cables, or other external devices that may be connected to the aerosol delivery system 1.

[0081] Electromagnetic radiation spectrum

[0082] It should be understood that the electromagnetic (EM) spectrum 1 It covers the range of all types of EM radiation, and includes:

[0083] • Ultraviolet (UV) light with wavelengths generally between 100 and 400 nm; 2

[0084] • Visible light with a wavelength of approximately 400 to 700 nm; 3 as well as

[0085] • Infrared (IR) light with a wavelength of approximately 700 nm to 1 mm. 4

[0086] It should also be understood that at our distance from the sun, the total solar irradiance is approximately 1360 W / m². 2 (1000W / m at sea level) 2), of which approximately: 5

[0087] 5% is UV light;

[0088] 42% is visible light; and

[0089] 53% is infrared radiation.

[0090] This disclosure outlines an aerosol delivery system that utilizes solar irradiation to reduce power consumption.

[0091] light absorption coefficient

[0092] In a claimed embodiment of the invention, the aerosol delivery system 1 includes a high-absorption portion 110 having an absorption coefficient of at least 0.95 for visible light with wavelengths in the range of 400 to 700 nm and / or infrared light with wavelengths in the range of 700 to 2000 nm. This embodiment provides a system 1 having a near-blackbody high-absorption portion 110, as defined by Planck's law of blackbody radiation, which efficiently absorbs incident radiation (a true blackbody absorbs all incident radiation, but such an ideal state is not perfectly achievable in practice). Therefore, the high-absorption portion 110 is readily heated by solar irradiation. Typically, aerosol delivery systems generate vapor by heating the aerosol-generating material from ambient temperature to temperatures exceeding 200°C. By (directly or indirectly) increasing the ambient temperature of the aerosol-generating material and / or the surrounding area, the power required to achieve evaporation can be reduced.

[0093] Advantageously, System 1 can have an absorption coefficient of at least 0.95 for wavelengths beyond those described above, particularly for infrared light having wavelengths in the range of 700 to 2500 nm or greater (e.g., up to 5000 nm, 10000 nm, 0.1 mm, or 1 mm) and / or UV light having wavelengths in the range of 100 to 400 nm, to further improve solar energy absorption. Therefore, in some examples, the high-absorption portion 110 can have an absorption coefficient of at least 0.95 for light having wavelengths in any one or more of the following ranges: 100 to 400 nm, 400 to 700 nm, 700 to 2000 nm, and / or 700-2500 nm, such as 400 to 2000 nm, 400 to 2500 nm, 100 to 700 nm, 100 to 2000 nm, and / or 100 to 2500 nm. In some examples, the absorption coefficient is ≥0.96, ≥0.97, ≥0.98, or ≥0.99.

[0094] In some examples, system 1 includes a reservoir 44 for holding aerosol-generating material, wherein the reservoir 44 itself includes a high-absorption portion 110. In some examples, system 1 is or includes a replaceable cartridge 4, which is used, for example in a wider system, with a separate reusable device portion 2 including a power source 26 (as referenced above). Figure 1 (As outlined); or System 1 may include a reusable device portion 2 for use with a replaceable cartridge 4 containing aerosol-generating material in a storage 44. In some examples, System 1 includes a cavity adjacent to the high-absorption portion 110 for receiving a storage 44 containing aerosol-generating material (e.g., in cartridge 4), wherein System 1 is configured to transfer absorbed irradiance (heat) to the aerosol-generating material in use. In one example, System 1 includes a thermally conductive element (e.g., comprising metal, adjacent to and in contact with the high-absorption portion 110) and is configured to receive, in use, a storage 44 containing aerosol-generating material adjacent to and in contact with the thermally conductive element (e.g., in cartridge 4), such that incident solar irradiation heats the high-absorption portion 110, and when cartridge 4 is installed in System 1, this heat is transferred by conduction via the thermally conductive element to the aerosol-generating material in storage 44. In a further example, system 1 includes a housing, which may be an outer shell or a casing, such as device portion housing 12 or cartridge portion housing 42, wherein housing 12, 42 includes a high-absorption portion 110.

[0095] Figures 2 to 4 This is a side view of the aerosol delivery system 1, including the high-absorption section 110. More specifically, Figure 2 This is a side view showing the main side of system 1. Figure 3 This mainly shows a side perspective view of the secondary side of system 1, and Figure 4 This is a perspective view mainly showing the main sides of system 1. Figures 2 to 4 In this system 1, a cartridge 4 includes a mouthpiece 49 having an aerosol outlet 50 for a user to inhale aerosol. The cartridge 4 also includes an internal reservoir 44 for retaining aerosol-generating material, and a high-absorption portion 110 having an absorption coefficient of at least 0.95 for visible light with wavelengths in the range of 400 to 700 nm and / or infrared light with wavelengths in the range of 700 to 2000 nm. In this example, the high-absorption portion 110 includes a carbon black outer surface located on the outer wall of the reservoir 44. In use, the high-absorption portion 110 may substantially surround the aerosol-generating material retained in the reservoir 44. In some examples, the surface or coating includes carbon nanotubes that absorb 98% to 99% of light in the spectral range from UV to far-infrared. 6 7In another example, the high-absorption portion 110 includes a surface coated with Musou black lacquer, which absorbs up to 99.4% of light in the visible light range—available at https: / / www.musoublack.com / 8 .exist Figures 2 to 4 In this example, the reservoir 44 does not extend into the nozzle 49. For hygiene reasons, the nozzle can be removed and replaced separately, and the nozzle 49 is transparent, thus lacking a high light absorption coefficient. In other examples, different configurations can be used, including a non-detachable / integrated nozzle 49.

[0096] like Figures 3 to 4 As best shown in the example, the reservoir 44 in this example is annular, surrounding the airflow path 52 formed by the tube passing through the cartridge 4. The reservoir 44 is defined by a reservoir wall that provides a cavity / chamber for receiving aerosol-generating material in use, which can be filled and may have a volume of 0.5 to 5 ml, typically 1.5 to 3 ml, or approximately 2 ml. In some examples, a high-absorption portion 110 surrounds the reservoir 44 or the cavity / chamber contained therein—for example, the high-absorption portion 110 may be formed (e.g., coated) on the wall of the reservoir 44, or the high-absorption portion 110 may be a wall of the reservoir 44 or a shell surrounding the reservoir 44. In some examples, the high-absorption portion 110 substantially or completely surrounds the reservoir 44, the cavity, or the chamber. The high-absorption portion 110 can generally have a diameter of substantially 400 to 2000 mm. 2 Surface area.

[0097] exist Figure 3 In the middle, the high-absorption portion 110 includes two high-absorption coatings 110a, 110b on the opposite main sidewalls of the reservoir 44, which extend around most but not the entire circumference of the cartridge 4. Figure 3 The storage 44 also includes a relative secondary sidewall that does not include the high absorption portion 110.

[0098] Storage 44 may generally include one or more walls, such as one or more sidewalls (e.g., the substantially vertical opposing main sidewalls where coatings 110a, 110b are located, plus...). Figure 3 The uncoated, substantially vertical, opposing secondary sidewalls of 110 and one or more end walls (e.g., Figure 3 (The top axial end wall and bottom axial end wall are perpendicular to the vertical opposite sidewalls). In some examples, the wall of the reservoir 44 itself or the wall surrounding the reservoir 44 (e.g., as part of the housing) may include a high-absorption portion 110. In some examples:

[0099] • One or more, or optionally all, walls have a high light absorption coefficient.

[0100] • At least 75%, 80%, 85%, 90%, 95%, or 100% of the surface area of ​​all walls (such as all outward-facing walls) exposed to solar radiation during use (e.g., outdoors) has a high light absorption coefficient.

[0101] • One, more than one, all, or all of the main sidewalls have a high light absorption coefficient. In some examples, when the sidewalls include a main (larger) sidewall and a secondary (smaller) sidewall, such as... Figure 3 As shown, the secondary sidewall may not include the high-absorption portion 110.

[0102] The end walls (the axial length perpendicular to the system length 1) may or may not have a high absorption coefficient because these end walls are only exposed to a limited extent to solar irradiation. Therefore, in some examples, the high-absorption portion 110 comprises a sleeve that substantially or completely surrounds the reservoir 44. Similarly, the above can also be applied to the walls of the housing surrounding the reservoir 44.

[0103] like Figure 3 As best shown, the reservoir 44 may include a window 120 located between or not covered by the two portions 110a, 110b of the high-absorption portion 110. The window 120 does not have a high light absorption coefficient—instead, the reservoir window 120 is transparent and allows the user to see the amount or level of aerosol-generating material in the reservoir 44. In other examples, the window 120 may be translucent rather than transparent. In this example, the reservoir window 120 extends primarily along the length of the reservoir 44—its width is relatively narrow, and it extends the entire length of the reservoir 44, having a width-to-length ratio of approximately 1:10 (for the avoidance of ambiguity, the length is parallel to...). Figure 4 The flow path 52 shown extends (as shown). Therefore, the user can observe any level of remaining quantity, with absorption of solar irradiance reduced to a minimum. In other examples, the reservoir window 120 may extend a portion of the length of the reservoir 44, ideally at least showing the bottom of the reservoir 44, so that the user can check if the reservoir 44 is empty, but not necessarily check if the reservoir 44 is substantially full. The reservoir window 120 may be located on one or more sides of the reservoir 44; here, the reservoir 44 includes windows 120 located on two secondary (narrower) sides.

[0104] Figure 4 It shows Figures 2 to 3The system 1 without the second high-absorption section 110b is shown in more detail of its internal construction. Details regarding the delivery of aerosol-generating material from the reservoir 44 to the aerosol generator 48, and the generation and entrainment of vapor in the airflow from the air inlet 28 and / or from the airflow path 51 through the reusable section 2 (not shown), are not central to the high-absorption function, but are shown for completeness. Figure 4 The arrows indicate these features—these features can be standard or, as referenced above. Figure 1 As described here, the high-absorption portion 110 may partially or substantially surround the aerosol generator 48, thereby allowing the aerosol generator 48 itself and any aerosol-generating material in its vicinity to be heated. Figure 4 The diagram also shows an elliptical air or vacuum chamber 150 spanning the top of the storage unit 44, which will be referenced later. Figure 6 Describe it.

[0105] Figure 5 It is used to receive Figures 2 to 4 A perspective view of device 2 of system 1 / cartridge 4, wherein device 2 includes a transparent housing 130 for receiving cartridge 4 during use. As described above, device 2 also includes a controller 22 and a power supply 26. See below for reference. Figure 6 The broader system 1 further describes the reusable device 2.

[0106] Figure 6 Is with Figure 5 The reusable device part 2 is combined Figures 2 to 4 A side perspective view of the aerosol delivery system 1. Figure 6 Several additional optional features are shown that could be advantageously provided to offer a “greenhouse” heat capture effect for absorbed solar irradiance. Figure 6 In, with Figure 4 Similarly, for clarity, only one portion / side 110a of the high-absorption portion 110 is shown.

[0107] First, system 1 may include a transparent shell or layer 130 substantially surrounding the high-absorption portion 110 (which itself may form part of a shell, such as part of device shell 12 or cartridge shell 42). Figure 6In this embodiment, the reusable portion 2 includes a transparent housing 130 extending circumferentially and axially away from the device body to form a cavity for receiving the cartridge 4. In use, the transparent housing 130 surrounds the high-absorption portion 110 of the cartridge 4 (spaced here by optional air or vacuum chambers 150, further described below). In this example, the transparent housing 130 can be reused for multiple cartridges 4 and provides a cavity for receiving a cartridge 4 comprising a reservoir 44 containing aerosol-generating material, the reservoir 44 including the high-absorption portion 110. In other examples, the cartridge 4 may also, or alternatively, include the transparent housing 130.

[0108] The transparent housing 130 itself may have a transmittance of at least 80%, at least 85%, at least 90%, or at least 95% for visible light with wavelengths in the range of 400 to 700 nm and / or for infrared light with wavelengths in the range of 700 to 2000 nm or 700 to 2500 nm. In some examples, the transparent housing 130 comprises a polycarbonate material, which typically has a transmittance of 80%. 9 Or higher transmittance, especially typical visible light transmittance of 85% to 88%. 10

[0109] Secondly, system 1 may include an air or vacuum gap 140, for example, located between the high-absorption portion 110 and the transparent housing 130, within the transparent housing 130, or within the reservoir 44. For the two-piece system 1, device 2 and / or cartridge 4 may include one or more air or vacuum gaps 140, which may be formed, for example, by an air or vacuum chamber 150 and / or formed as part of the transparent housing 130. Figure 6 In this device, the reusable portion 2 includes an air or vacuum chamber 150 surrounding a cavity for receiving a cartridge 4 adjacent to the chamber 150. The air or vacuum chamber 150 may include multiple sections that may be located within the device 2 and / or the cartridge 4. Figure 6 In the middle, chamber 150 includes: two opposing arc-shaped main side chambers 150a and 150c, having the same arc-shaped profile as the high-absorption portions 110a and 110b (note that, for clarity, the arc-shaped profile is...). Figure 6 (Not fully shown); and two opposing elliptical end chambers 150b, 150d, extending perpendicular to the length of system 1. In this example, device 2 includes two opposing main side chambers 150a, 150c and a first elliptical end chamber 150d away from mouthpiece 49, while cartridge 4 includes a second elliptical end chamber 150b near mouthpiece 49, as shown in the image. Figure 4 As shown. In Figure 6In this system 1, there is no chamber 150 around the secondary axial sides because these secondary axial sides do not include the high absorption portion 110, but instead include the transparent window 120.

[0110] Although Figure 6 While not described in detail, the air gap / vacuum 140 or chamber 150 may substantially or completely surround the aerosol generator 48, reservoir 44, and / or high-absorption section 110 to minimize heat loss. In some examples, the air gap / vacuum 140 or chamber 150 substantially surrounds / encloses all sidewalls of the aerosol generator 48 and / or reservoir 44, as these include the high-absorption section 110, which is exposed to solar radiation during use. The profile of the air gap / vacuum 140 or chamber 150 may reflect the profile of the high-absorption section 110. In some examples, the air gap / vacuum 140 or chamber 150 is annular.

[0111] An air or vacuum chamber 150 may be adjacent to or part of the transparent housing 130 or the reservoir 44, such as being integrated with or contained therein. In other words, the reservoir 44 or the transparent housing 130 may include an air / vacuum gap 140 or a chamber 150, for example, by including an outer wall, an inner wall, and an air or vacuum chamber 150 located between the inner and outer walls. In this example, a device 2 including three air or vacuum chambers 150a, 150c, and 150d can be reused for multiple cartridges 4, in which the cartridge has an air or vacuum chamber 150b. In other examples, the cartridge 4 may not include an air or vacuum chamber 150, but may include one or more air or vacuum chambers, for example, adjacent to or part of the high-absorption portion 110, the cartridge housing 42, or the reservoir 44, such as being integrated with or contained therein.

[0112] In these examples, solar irradiance absorbed by the high-absorption portion 110 is captured by system 1, limiting the emissivity of the absorbed energy because it radiates heat in the infrared band when it absorbs EM energy and heats itself. However, infrared radiation has poor penetrability and therefore cannot effectively pass through the transparent housing 130 or through the air / vacuum gap 140 (where such an air / vacuum gap also minimizes heat loss due to conduction and convection). Thus, solar irradiance energy is absorbed to heat the high-absorption portion 110, which heats the smoke bomb 4, while the transparent housing 130 and the air / vacuum gap 140 limit the loss of absorbed energy returning to the environment. In this way, the energy consumed to heat the e-liquid to a certain temperature is reduced. This also provides a more efficient direct system than using PV panels to convert solar irradiance into electricity.

[0113] Furthermore, system 1 may include a highly reflective portion 160. Specifically, such as Figure 6 As shown, system 1 may include a housing 12 for receiving power supply 26, wherein the housing includes a highly reflective portion 160 having a reflectivity of at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, or at least 95% for visible light having wavelengths in the range of 400 to 700 nm and / or infrared light having wavelengths in the range of 700 to 2000 nm. Conversely, the highly reflective portion 160 reflects rather than absorbs incident solar radiation, and thus minimizes heat generation of power supply 26, which could otherwise shorten its lifespan.

[0114] Although not shown in detail in the figures, in some examples, the transparent housing 130 may include an electrochromic material, i.e., a material that can change color or opacity in response to electrical stimulation. In such examples, the transparent housing 130 may be operable to provide suitable transmittance (as described above) when conditions permit, but may also be adjustable, for example, according to internal system environmental conditions and / or external environmental conditions. System 1 may include a controller 22 configured to control the electrochromic material in response to internal / external environments, which may be sensed and / or transmitted to System 1 by one or more sensors.

[0115] Figure 7 and Figure 8 These are schematic cross-sectional and end views of system 1, which includes a reservoir 44 for aerosol-generating materials, a high-absorption section 110, an air or vacuum chamber 150, and a transparent housing 130.

[0116] Figure 7 The cross-sectional view schematically illustrates how the reservoir 44, the high-absorption section 110, the air or vacuum chamber 150, and the transparent shell 130 are effectively arranged as layers in the aerosol delivery system 1 to facilitate heating of the aerosol-generating material by solar irradiation and minimize losses returning to the environment. As described above, solar irradiation can pass through the transparent shell 130 and radiate through the air / vacuum gap formed by the air or vacuum chamber 150, whereby it is absorbed by the high-absorption section 110 and converted into heat. This heat energy is radiated in the infrared band, which cannot be effectively transmitted back through the air / vacuum gap 140 or the transparent shell 130. In embodiments, these features may be selectively provided in the integrated disposable system 1, or they may be provided in one or both of the reusable device 2 and the removable / replaceable cartridge 4.

[0117] Figure 7 Several two-piece systems 1 are schematically outlined, including:

[0118] i. A reusable device 2a includes a transparent housing 130, an air or vacuum chamber 150, and a high-absorption portion 110 (optionally, for example, as a layer of the housing), wherein the device 2a is configured to receive a cartridge 4a, which may be conventional and includes a storage 44 for aerosol-generating materials.

[0119] ii. A reusable device 2b comprising a transparent housing 130 and an air or vacuum chamber 150, wherein the device 2b is configured to receive a cartridge 4b, the cartridge comprising a reservoir 44 for aerosol-generating material and a high-absorption portion 110; and

[0120] iii. A reusable device 2c, comprising a transparent housing 130, wherein the device 2c is configured to receive a cartridge 4c, the cartridge comprising a reservoir 44 for aerosol generating material, a high-absorption portion 110, and an air or vacuum chamber 150.

[0121] Note that the above is not exhaustive and other combinations are conceivable, specifically, for example, omitting one or more of the air or vacuum chamber 150 and the transparent housing 130; or providing multiple air or vacuum chambers 150 and / or transparent housings 130, optionally in multiple portions thereof.

[0122] Figure 8 It shows the relationship with Figure 7 The same arrangement, in which each element has a circular cross-section, effectively forms a series of layers, wherein the high-absorption portion 110 is annular, surrounding the reservoir 44, and the transparent housing 130 and the air or vacuum chamber 150 are also annular, surrounding the high-absorption portion 110, and therefore also surrounding the reservoir 44. In other examples, any other shape may be used.

Optionally, a solvent (such as water) may also be present, and one or more other components of the aerosol-generating material may be soluble in the solvent or insoluble in the solvent. In some embodiments, the aerosol-generating material is substantially free of plant material. Specifically, in some embodiments, the aerosol-generating material is substantially free of tobacco.

[0156] Aerosol generating materials may include or be in the form of aerosol generating membranes. Aerosol generating membranes may include binders (such as gelling agents) and aerosol forming agents. Optionally, a substance to be transported and / or fillers may also be present. Aerosol generating membranes may be substantially free of plant material. Specifically, in some embodiments, the aerosol generating material is substantially free of tobacco. Aerosol generating membranes may have a thickness of about 0.015 mm to about 1 mm. For example, the thickness may be in the range of about 0.05 mm, 0.1 mm, or 0.15 mm to about 0.5 mm or 0.3 mm. Aerosol generating materials may include more than one membrane, and the thickness described herein may refer to the total thickness of those membranes.

[0157] Aerosol-generating membranes can be continuous. For example, the membrane may comprise or be a continuous sheet of material. The sheet may be in the form of packaging paper, which may be aggregated to form an aggregated sheet, or it may be shredded to form shredded material. Shredded material may comprise one or more strands or strips of aerosol-generating material. Aerosol-generating membranes can also be discontinuous. For example, an aerosol-generating membrane may comprise one or more discrete portions or regions of aerosol-generating material, such as points, strips, or lines that may be supported on a support. In such embodiments, the support may be planar or non-planar.

[0158] Aerosol-generating membranes can be formed by combining a binder (such as a gelling agent) with a solvent (such as water), an aerosol forming agent, and one or more other components (such as one or more substances to be transported) to form a slurry, and then heating the slurry to atomize at least some of the solvent to form an aerosol-generating membrane. The slurry can be heated to remove at least about 60 wt%, 70 wt%, 80 wt%, 85 wt%, or 90 wt% of the solvent.

[0159] Aerosol-generating materials may include or may be "amorphous solids". In some embodiments, the aerosol-generating material includes an aerosol-generating membrane that is an amorphous solid. The amorphous solid may be a "monolithic solid". The amorphous solid may be substantially non-fibrous. In some embodiments, the amorphous solid may be a dried gel. An amorphous solid is a solid material that can retain some fluid (such as a liquid) within it. In some embodiments, the amorphous solid may, for example, comprise from about 50 wt%, 60 wt%, or 70 wt% to about 90 wt%, 95 wt%, or 100 wt% of amorphous solids.

[0160] Amorphous solids may be substantially free of plant material. Amorphous solids may be substantially free of tobacco.

In some embodiments, the support includes a receptor. In some embodiments, the receptor is embedded within the material. In some alternative embodiments, the receptor is on one or both sides of the material.

[0167] Consumables

[0168] 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, an aerosol-generating material delivery component, an aerosol-generating area, a housing, packaging paper, a nozzle, a filter, and / or an aerosol modifier. Consumables may also include an aerosol generator, such as a heater, which releases heat during use to cause the aerosol-generating material to generate an aerosol. For example, the heater may include a combustible material, a material that can be heated by electrical conduction, or a sensor.

[0169] receptors

[0170] A sensor is a material that can be heated by the penetration of a changing magnetic field (such as an alternating magnetic field). A sensor can be a conductive material, causing induction heating of the heating material by the penetration of a changing magnetic field. A heating material can be a magnetic material, causing hysteresis heating of the heating material by the penetration of a changing magnetic field. A sensor can be both conductive and magnetic, allowing it to be heated by both heating mechanisms. In this paper, a device configured to generate a changing magnetic field is referred to as a magnetic field generator.

[0171] Aerosol Modifier

[0172] 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. For example, aerosol modifiers can be additives or adsorbents. For example, aerosol modifiers may include one or more of flavoring agents, coloring agents, water, and carbon adsorbents. For example, aerosol modifiers can be solid, liquid, or gel. Aerosol modifiers can be in powder, filament, or granular form. Aerosol modifiers may not contain filter material.

[0173] Aerosol generator

[0174] An aerosol generator is a device configured to generate aerosols from an aerosol-generating material. In some embodiments, the aerosol generator is a heater configured to subject the aerosol-generating material to heat energy in order to release one or more volatiles from the aerosol-generating material to form an aerosol. In some embodiments, the aerosol generator is configured to generate aerosols from the aerosol-generating material without heating. For example, the aerosol generator may be configured to subject the aerosol-generating material to one or more of vibration, increased pressure, or electrostatic energy.

[0175] This disclosure relates to aerosol delivery systems (which may also be referred to as vapor delivery systems), such as aerosol sprayers or electronic cigarettes. Throughout the following description, the terms "electronic cigarette" or "electronic cigarette" may sometimes be used, but it will be understood that these terms are used interchangeably with aerosol delivery systems / devices and electronic aerosol delivery systems / devices. Furthermore, and as is common in the art, the terms "aerosol" and "vapor," as well as related terms such as "evaporation," "atomization," and "aerosolization," are generally used interchangeably.

[0176] Aerosol delivery systems (electronic cigarettes) typically (though not always) comprise modular components, including a reusable device section and a replaceable (disposable / consumable) cartridge section. Typically, the replaceable cartridge section will include aerosol generating material and an vaporizer (which may be collectively referred to as an 'atomizer'), while the reusable device section will include a power source (e.g., a rechargeable power source) and control circuitry. It will be understood that these different sections may include additional components depending on their function. For example, the reusable device section will typically include a user interface for receiving user input and displaying operational status characteristics, and the replaceable cartridge section may include, in some cases, a temperature sensor to aid in temperature control. The cartridge is electrically and mechanically connected to the control unit for use, for example, using threads, bayonet connections, or magnetic connections with suitably arranged electrical contacts. When the aerosol generating material in the cartridge is depleted, or when the user wishes to switch to a different cartridge with a different aerosol generating material, the cartridge can be removed from the reusable section, and a replacement cartridge can be attached to its appropriate position. Systems and devices that conform to this type of two-piece modular configuration can generally be referred to as two-piece systems / devices.

[0177] Electronic cigarettes typically have a generally elongated shape. For the sake of specific example, certain embodiments of this disclosure will be considered to include such a generally elongated two-piece system employing a disposable cartridge. However, it will be understood that the basic principles described herein can be equally applied to different configurations, such as a single-piece system or a modular system comprising more than two parts, refillable devices and single-use disposable items, and other overall shapes, such as high-performance devices based on a so-called box-shaped pattern that typically has a box-like shape. More generally, it will be understood that certain embodiments of this disclosure are based on an aerosol delivery system that is operationally configured to provide the functionality according to the principles described herein, and the construction aspects of the system configured to provide the functionality according to certain embodiments of this disclosure are not particularly important.

[0178] Throughout this disclosure, unless otherwise indicated, the terms 'basically,' 'about' and 'approximately' should be considered to mean within + / - 10%.
