Description

[Technical field]

[0001] The present invention relates to a component part, an aerosol delivery device, an aerosol delivery system, an aerosol generating system, a method for generating an aerosol from the component parts, and an aerosol delivery means.

[0002] Aerosol delivery systems are well known. Typical systems use a heater to generate an aerosol from an aerosol-generating material, which is then inhaled by the user. The aerosol-generating material from which the aerosol is generated is consumed during use of the aerosol delivery system. Heating the aerosol-generating material can cause it to change structurally. Over time, as the aerosol-generating material is consumed, the structural changes can reduce the user's taste for the aerosol delivery system by changing flavors or making it more difficult to use. Modern systems often use a predefined effective use time for the system, which refers to the consumption of the aerosol-generating material in the system.

[0003] It is desirable for an aerosol delivery system to avoid heating the depleted aerosol-forming material and developing undesirable flavors and odors.

[0004] The present invention is directed to solving some of the problems mentioned above.

While the invention is susceptible to various modifications and alternative forms, specific embodiments have been shown by way of example in the drawings and are described in detail herein. It should be understood, however, that the drawings and detailed description of the specific embodiments are not intended to limit the invention to the specific forms disclosed. On the contrary, the invention covers all modifications, equivalents, and alternatives falling within the scope of the invention as defined by the appended claims. Detailed Description

[0013] Aspects and features of some examples and embodiments are discussed / described herein. Some aspects and features of some examples and embodiments may be conventionally implemented, and for the sake of brevity, such aspects and features will not be discussed / described in detail. Thus, it should be understood that aspects and features of the apparatus and methods discussed herein but not described in detail may be implemented according to any conventional technique for implementing such aspects and features.

[0014] The present disclosure relates to an aerosol delivery system, which may also be referred to as an aerosol delivery system, such as an e-cigarette. According to the present disclosure, a "non-flammable" aerosol delivery system is one that does not burn or scorch the aerosolizable composition material (or components of the aerosol delivery system) of the aerosol delivery system to facilitate delivery to a user. Throughout the following description, the term "e-cigarette" or "electronic cigarette" may sometimes be used, but it should be understood that the term can be used interchangeably with aerosol delivery system / device and electronic aerosol delivery system / device. Additionally, as is common in the art, the terms "aerosol" and "vapor" and related terms such as "evaporate", "volatilize" and "aerosolize" can generally be used interchangeably.

[0015] In the example of Figure 1, a component part 100 is shown for use in an aerosol delivery system. In use, the component part 100 can be inserted or connected to the aerosol delivery system. The aerosol delivery system can generate an aerosol. The component part 100 includes a region 110 through which, in use, an aerosol from the aerosol delivery system can pass. The component part 100 is configured to allow the aerosol to selectively interact with a substance disposable within the region 110.

[0016] In the example shown in FIG. 1, the aerosol delivered by the aerosol delivery system is indicated by arrow A. The component part 100 is used in the aerosol delivery system downstream of the aerosol-generating portion of the aerosol delivery system. In that way, the aerosol stream enters the component part 100. This aerosol mainstream is indicated by arrow A in FIG. 1. The aerosol mainstream A can be split into smaller aerosol streams that together form the aerosol mainstream A. These smaller aerosol streams are represented by arrows B, C, D. These smaller aerosol streams B, C, D flow into the region 110. The component part 100 can be configured to allow the aerosol to selectively interact with a substance disposable in the region 110. In one example, the component part 100 can be configured to selectively allow one or two of the smaller aerosol streams B, C, D to flow into the region 110. In that way, the component part 100 allows the aerosol mainstream A to selectively interact with a substance disposable in the region 110.

[0017] The substance may be an active substance or a flavouring or both. The flavouring may be an olfactory substance, etc. The active substance may be, for example, caffeine, etc.

[0018] In the example of FIG. 2, an example of a component part 200 is shown. The component part 200 has a region 210 and a guide element 220. The guide element 220 is configured to guide the aerosol through the region 210 in a controlled manner. In the particular example shown, the guide element 220 has a series of segments. In FIG. 2, the guide element 220 is generally cylindrically shaped and has six sectors extending along the entire cylindrical length of the guide element 220. Three sectors 222, 224, 226 are specifically shown. When the aerosol A enters the component part 200, the aerosol A can pass through, for example, the first sector 222 to form a smaller aerosol flow B downstream of the guide element 220. In another example, the aerosol A can pass through the second sector 224 to form a smaller aerosol flow C downstream of the guide element 220. In yet another example, the aerosol A can pass through the third sector element 226 and form a smaller aerosol flow D downstream of the guiding element 220 .

[0019] In one example, guide element 220 can be a control element or the like that controls (e.g., blocks or allows) aerosol to pass through portions of region 210. Guide element 220 can also be a filter or a series of filters, or a valve or a series of valves. Guide element 220 can have a series of doors that can be opened or closed to allow or deny passage of aerosol through certain doors.

[0020] Aerosol A is prevented from passing through one portion of the guide element 220 and permitted to pass through another portion of the guide element 220. Thus, aerosol A is controlled as to which portion of the region 210 the aerosol flows into. Although the term "smaller aerosol flow" has been used to refer to arrows B, C, and D, the total amount of aerosol entering and exiting the component part 200 is substantially the same since the aerosol is not nearly lost or trapped within the component part 220. Thus, the "smaller aerosol flow" refers to the aerosol flowing through an area downstream of the guide element 220 that is smaller than the larger aerosol flow entering the component part 220.

[0021] In the example of Fig. 3, an example of a guide element 320 is shown. The guide element 320 is shown end-on. The guide element 320 has a number of compartments separated from each other. There are eight compartments 321, 322, 323, 324, 325, 326, 327, 328 shown in the figure. The compartments 321, 322, 323, 324, 325, 326, 327, 328 can be separated from each other by a frame or a similar structure. The frame is advantageously impermeable to aerosols so as to ensure that an aerosol that enters a particular compartment flows through that compartment and is prevented from entering another compartment. In this way, the guide element 320 can control the flow of aerosols through the guide element 320.

[0022] When the guide element 320 is disposed within the component part, it can controllably force the aerosol into one (or more) of the compartments 321, 322, 323, 324, 325, 326, 327, 328 of the guide element 320 and, thus, into the corresponding compartment of the region of the component part. The guide element 320 can be adjacent or substantially adjacent to a substance (e.g., a fragrance ingredient or an active substance) within the region. This arrangement increases the likelihood that the aerosol will pass through the compartment of the corresponding substance.

[0023] Broad control over the portion of the material through which the aerosol flows provides a number of advantages. As the aerosol flows through the material, the heat and moisture of the aerosol can structurally degrade the material. Thus, after repeated use, the material can become structurally degraded, resulting in no further passage of the aerosol through the material. By controlling the portion of the material through which the aerosol flows, the device can ensure that only a portion of the material through which the aerosol flows is replaced after that portion has been structurally degraded.

[0024] Furthermore, the aerosol can be prevented from flowing through depleted portions of the substance known to generate harmful compounds entrained in the aerosol, thus improving the user's taste. The depletion of a particular portion of substance can be detected, for example, by a combination of a sensor and a control unit. The depletion can be timed, for example, based on time of use or number of puffs. The depletion may also be detected by analysis of the compounds entrained in the aerosol. After depletion is detected, or after a predefined time limit has been exhausted, or even when replacement of the compartments is simply desired, the guide element 20 can be controlled to cause the aerosol to follow different compartments 321, 322, 323, 324, 325, 326, 327, 328 and thus pass through different compartments of the substance.

[0025] The substance may contain multiple substance compounds that provide the compounds to be entrained in the aerosol. Different sections of the substance may thus be provided with different compounds to be entrained. Thus, the guide element 320 may direct the aerosol through a first section 321, causing the aerosol to carry a first substance compound (or compounds). The guide element 320 may then direct the aerosol through a second section 322, causing the aerosol to carry a second substance compound (or compounds). The substance may be, for example, tobacco, nicotine-containing, menthol, glycol, caffeine, or any other active substance.

[0026] Thus, the divided parts of the guide element 320 can, for example, be opened or closed to allow the passage of the aerosol. The guide element 320 can additionally or alternatively be configured to be controllably movable. The movement of the guide element 320 can make it possible to controllably vary the flow path of the aerosol. The movement of the guide element 320 can leave only one open section open and move to make it possible to vary the flow path of the aerosol.

[0027] In the example of Figure 4, an example of a guide element 420 is shown. The illustrated guide element 420 varies from the guide element 320 shown in Figure 3. The illustrated guide element 420 has an open section 427 through which the aerosol can pass and a closed section 425 through which the aerosol is prevented from passing. Thus, the guide element 420 only allows the aerosol to pass through the open section 427. The guide element 420 is movable to move the position of the open section 427, which can correspondingly affect the flow path of the aerosol.

[0028] In one example, since the illustrated guide element 420 is circular (note that expressly this is not a limitation to the guide elements disclosed herein), the guide element 420 can rotate in the direction indicated by arrow R. Rotation of the guide element 420 can move the open section 427, thereby causing the aerosol to pass through different locations and through different portions of the material within the component part. This rotation can be about an axis substantially parallel to the longitudinal axis of the component part. This can be rotation substantially about the central axis of the guide element 420.

[0029] As noted above, movement of the guide element 420 may be automatic (e.g., by a sensor and control arrangement) or manual, such as by user input. The guide element 420 may be shaped to correspond to the shape of the component part housing. In this way, aerosol may be prevented from passing between the component part housing and the guide element 420. This allows for a higher level of control over the aerosol flow path.

[0030] The guide element may be formed from a number of actuatable elements. Returning to Fig. 3, each compartment 321, 322, 323, 324, 325, 326, 327, 328 may have, for example, a respective openable / closable door to control the aerosol flow through the compartment 321, 322, 323, 324, 325, 326, 327, 328. The doors may be configured to move individually (or in groups) from a respective first position to a respective second position in use. The respective first positions may allow the aerosol to flow past the actuatable elements. The respective second positions may prevent the aerosol from flowing past the actuatable elements. The actuatable elements may be doors, a series of windows, valves, or actuatable switches, etc.

[0031] The controlled movement of these elements may be the result of a sensor and control arrangement, as described above, or by user input. Multiple actuatable elements may be movable relative to one another. This allows individual elements to be selectively moved to controllably open individual sections 321, 322, 323, 324, 325, 326, 327, 328 of the guide element 320.

[0032] In one example, the component includes a controller configured to receive a signal related to the operation of the guide element 320 and to control the operation of the guide element 320. The signal received by the controller is provided by a sensor that may or may not be part of the component. The sensor may be part of a larger aerosol delivery system in which the component is used.

[0033] The sensor can detect puffs of the system and instruct the control to activate the guide element 320 (or a portion of the guide element, e.g., a door to a compartment) after a predefined number of puffs. This can ensure that a particular substance compartment is not used (i.e., does not allow aerosol to be sent through it) until it is depleted or near depletion. Alternatively or additionally, the sensor can detect a pressure change. As a substance compartment is depleted, structural degradation can cause an increase in flow pressure as it gradually blocks aerosol from flowing through the compartment. At a predefined pressure, the sensor can send a signal to the control, which further activates the guide element 320. Alternatively or additionally, the user can instruct the control to activate the guide element 320. This can be when the user wishes to vary the substance entrained in the aerosol (especially when the substance contains multiple substance compounds in various compartments). The user can interact with the control via an electrical interface, such as a GUI, or via a mechanical interface, such as a button.

[0034] The controller can be connected to an actuation mechanism that actuates the guide element 320 or a sub-portion thereof. The actuation mechanism can be part of the guide element 320 or a component part. The phrase "the controller actuates the guide element" is intended to mean that the controller controls the operation of the guide element in some manner, such as by sending a signal to a mechanical element, which in turn actuates the guide element.

[0035] In the example of FIG. 5, an example of a portion of an aerosol delivery system 500 is shown. The example of the portion of the aerosol delivery system 500 is shown in a longitudinal cross-section. The aerosol delivery system 500 has a housing 501 having an inlet 502 and an outlet 503. Aerosol can enter the portion of the aerosol delivery system 500 shown through the inlet 502. The incoming aerosol is indicated by arrow E. The aerosol delivery system 500 has a component part 505 arranged within the aerosol delivery system 500. The component part 505 has a substance region 510 that receives a substance during use. The component part 505 has a guide element 520 for controlled guidance of the aerosol through the substance region 510. The component part 505 fits snugly within the housing 501 of the aerosol delivery system 500. This prevents the aerosol E from flowing between the housing 501 and the component part 505. Substance region 510 is shown adjacent to guide element 520 such that guide element 520 effectively controls aerosol flow into a particular section of material within substance region 510. Guide element 520 fits snugly within component part 505 to prevent aerosol E from flowing between component part 505 and guide element 520.

[0036] 5 allows for a good level of control over the path the aerosol takes within component part 505. This increased control translates into improved user experience with system 500 for a variety of reasons previously enumerated. Aerosol delivery system 500 may further comprise a cartomizer, atomizer, etc. (not shown) for delivering the aerosol. Component part 505 may further comprise controls, sensors, actuation mechanisms, etc. (all not shown), as described above. Outlet 503 may be a mouthpiece through which the user may inhale.

[0037] In the example of Fig. 6, an example of a portion of an aerosol delivery system 600 is shown. The aerosol delivery system 600 differs from the aerosol delivery system 500 shown in the example of Fig. 5. The aerosol delivery system 600 comprises a housing 601 having an inlet 602 and an outlet 603, and a component part 605 having a guide element 620. The aerosol delivery system 600 comprises a substance region 610, which contains a substance in use. The aerosol delivery system 600 further comprises an empty channel 630, which does not contain a substance in use. The aerosol flowing through the aerosol delivery system 600 is indicated by arrow F.

[0038] In one example, guiding element 620 of aerosol delivery system 600 can allow aerosol F to selectively interact with a substance disposable in the substance region, as indicated by arrow G. Guiding element 620 can further allow aerosol F not to selectively interact with the substance by directing aerosol F through channel 630, as indicated by arrow H. Channel 630 is devoid of the substance.

[0039] By controlling the guide element 620, the user can optionally add a substance to the aerosol F passing through the aerosol delivery system 600. Alternatively, the user can obtain only the aerosol for inhalation without the optional addition of a substance. The guide element 620 can have a series of actuatable elements, one or more of which are actuatable to allow the aerosol to pass through a portion of the substance region 610 and one or more of which are actuatable to allow the aerosol to pass through a portion of the channel 630. The aerosol delivery system 600 can further have actuatable elements associated with the openings 633, 613 to prevent the aerosol flowing through the channel 630 from entering the substance region 610 through the opening 613 to the substance region. Additionally, the user's inhalation encourages airflow through either the substance region 610 or the channel 630 to flow out the outlet 603 without returning through both openings 613, 633.

[0040] To avoid impairing the user's taste, the pressure drop across channel 630 should be similar to the pressure drop across substance region 610, which receives the substance during use. The user should not be required to suck very hard on aerosol delivery system 600 to force aerosol F through the substance in substance region 610. Thus, the placement of the substance within substance region 610 should be such that there is no significant pressure drop between channels 610 with substance and channels 630 without substance.

[0041] 6 may be external to component part 605, i.e., guide element 620 may be part of a section of aerosol delivery system 600 adjacent to component part 605. In this example, component part 605 may have two channels, and airflow through those channels may be controllable by guide element 620 of aerosol delivery system 600.

[0042] Any of the example guiding elements described herein may be formed at least in part from smart materials. The term "smart material" is used herein to mean a material that can change structure upon receiving a particular stimulus. Smart materials may also be referred to by the terms "intelligent materials", "responsive materials" or "designed materials". Such stimuli may be electrical, thermal, pressure, magnetic field, light, pH, etc. Smart materials change shape more than normal materials that naturally change structure to some degree (albeit more limited than smart materials) upon temperature or pressure changes. Piezoelectric materials may be an example of a smart material. Such smart materials may be used such that the guiding elements can be actuated or manipulated to actuate by stimuli, for example, rather than actuating the guiding elements by an actuation mechanism. This may lead to fewer components in the aerosol delivery system and therefore a longer life for the system.

[0043] In one example, the substance region can be configured to exclude substances from one or more particular portions. In this way, the system can be configured to allow the aerosol flow through the corresponding guiding element and portion of the substance region, so that the aerosol does not entrain compounds from the substance in the substance region. In this way, users who prefer only aerosol without added substances can be provided with such.

[0044] In the example of Fig. 7, an example of a portion of an aerosol delivery system 700 is shown. The aerosol delivery system 700 differs from the aerosol delivery systems 500, 600 shown in the examples of Figs. 5 and 6 described so far. The aerosol delivery system 700 has two guiding elements 720, 740. The aerosol delivery system 700 has a material region 710 that receives a material during use. The aerosol flowing through the aerosol delivery system 700 is indicated by arrows H.

[0045] The illustrated first guiding element 720 has an open section 747 through which the aerosol can pass and a closed section 745 through which the aerosol is prevented from passing. The first guiding element 720 shown in Fig. 7 is similar to the guiding element 420 shown and described with reference to Fig. 4. When the aerosol H enters the first guiding element 720, it is forced through the open section 747 to form aerosol I. Upon passing through the open section 747, the aerosol H is directed into aerosol I whose direction can be controlled.

[0046] The aerosol I then flows into the second guide element 720. The guide element 720 is similar to the guide element 320 shown and described with reference to FIG. 3. The second guide element 720 has a number of compartments separated from each other. There are six compartments shown in FIG. 7. The compartments can be separated from each other by a frame or a similar structure. The aerosol I can be controlled to pass through one or more compartments. The number of compartments through which the aerosol I passes can be controlled by the relative dimensions of the open compartments 747 of the first guide element 740 and the compartments of the second guide element 720. Similarly, an openable element can be used to prevent or allow the aerosol I to pass through the compartments of the second guide element 720, as previously explained. The aerosol passing through the guide element 720 is indicated by the arrow J. This aerosol then flows into the substance area 710, in which the substance is placed during use.

[0047] As mentioned above, it is advantageous to control the aerosols I, J by arranging the first guide element 740 adjacent to the second guide element 740 and the second guide element 720 adjacent to the substance region 710. This helps to prevent the aerosol from being swept away from the flow path it is currently in by one guide element that will then be swept out of it. This can be advantageously avoided by using adjacent elements.

[0048] To further explain this, if there is a reasonable distance between the first guiding element 740 and the second guiding element 720, the open section 747 allows the aerosol to flow through, for example, two specific sections of the second guiding element 720. In one example, the aerosol H is flowed through the open section 747 to form an aerosol I intended to pass through the target specific sections 721, 722. However, the distance between the first guiding element 740 and the second guiding element 720 means that the aerosol I spreads while leaving the open section 747 and reaching the second guiding element 720. As a result, the aerosol I passes through the intended specific sections 721, 722 as well as the unintended sections 723 and 724. This may result in undesired parts of the substance in the substance area being entrained in the aerosol, providing an aerosol for inhalation that is not desired by the user.

[0049] The elements shown in Figure 7 can be fully or partially housed within a component part of the type previously described. The aerosol can be formed by heating an aerosol-generating material or the like, which can be done in a heating section of the aerosol delivery system. The aerosol-generating section is in fluid communication with the component part shown in Figure 7, whereby the aerosol can be delivered to the guiding element and passed through the perfume region in a controlled manner.

[0050] In one example of the invention, the guide element may be housed in the aerosol delivery system or device rather than in the component part. The component part may then be inserted into the aerosol delivery device prior to use, such that the guide element controls the flow of the aerosol through the component part. In this example, the component part may be inserted into the aerosol delivery device such that it abuts against the guide element. The advantage of this arrangement relates to better control of the aerosol flow, which relates to the level of precision with which the aerosol flow can be forced through the material region.

[0051] In such examples, the aerosol delivery device may further include a controller that receives a signal regarding actuation of the guide element. The signal may be generated by a user, from a sensor, or the like. The sensor may be located on the aerosol delivery device or a component part and connected to the controller. In either example, the controller may be electrically or wirelessly connected to the sensor.

[0052] The aerosol delivery device may have an area for storing the aerosol-forming medium, which area stores the aerosol-forming medium during use. The aerosol, the flow of which is controlled by the guiding element, may be formed from the aerosol-forming medium, such as by a cartomizer or atomizer.

[0053] In a particular example of the invention, an aerosol generating system is provided that is configured to generate an aerosol with a maximum temperature of 400° C. A maximum temperature of 400° C. can prevent combustion of the material in the material region. Thus, a system with a maximum temperature of 400° C. having selective bypass of the aerosol is disclosed. The selective bypass is realized, for example, by an element formed from a smart material.

[0054] Any of the disclosed aerosol delivery systems may have control circuitry configured to control the heating that generates the aerosol, receive signals from a sensor or a user, and / or control operation of the guidance elements (or portions of the guidance elements), etc. The control or control circuitry may be connected to a database that determines when certain predefined values ​​exceed or fall outside of predefined ranges. This may lead to controlling operation of the guidance elements, etc. to control the flow of aerosol through the aerosol delivery system.

[0055] In some embodiments, the non-combustion aerosol delivery system is an e-cigarette, also known as a vaping device or electronic nicotine delivery system (END), although it should be noted that the presence of nicotine in the aerosolizable material is not a requirement.

[0056] In some embodiments, the non-combustion aerosol delivery system is a tobacco heating system, also known as a non-combustion heating system.

[0057] In some embodiments, the non-combustion aerosol delivery system is a hybrid system that uses a combination of multiple aerosolizable materials to generate the aerosol, one or more of which may be heated. Each of the aerosolizable materials may be in the form of, for example, a solid, liquid, or gel, and may or may not contain nicotine. In some embodiments, the hybrid system may include a liquid or gel aerosolizable material, and a solid aerosolizable material. The solid aerosolizable material may include, for example, tobacco or a non-tobacco product.

[0058] Generally, a non-combustion aerosol delivery system may comprise a non-combustion aerosol delivery device and an article for use with the non-combustion aerosol delivery device, although it should be understood that articles that themselves comprise means for energizing an aerosol generating component may themselves form a non-combustion aerosol delivery system.

[0059] In some embodiments, the non-combustion aerosol delivery device can include a power source and a controller. The power source can be, for example, a power source.

[0060] In some embodiments, an article for use with a non-combustion aerosol delivery device can include an aerosolizable material, an aerosol-forming component, an aerosol-forming region, a mouthpiece, and / or a region for receiving an aerosolizable material.

[0061] In some embodiments, the aerosol-generating component is a heat-generating agent capable of interacting with the aerosolizable material to cause one or more volatile substances to separate from the aerosolizable material to form an aerosol.
