Description

[Technical field]

[0001] The present invention relates to an aerosol delivery system, a method for generating an aerosol from an aerosol delivery system, an aerosol delivery means, and an electronic aerosol delivery system. [Background technology]

[0002] Aerosol delivery systems are known. Aerosol delivery systems often have an energy reservoir that provides energy that, in use, allows the aerosol generating medium to be aerosolized prior to inhalation by the user. Most modern devices operate on demand, as a result of the user pressing a button or inhaling on the device before a puff is delivered to the user. Such devices rapidly deliver energy from the energy reservoir to the aerosol generating mechanism of the device, shortening the time between the user's indication of a request for a puff and the delivery of the puff.

[0003] It is desirable to reduce the time between an instruction requesting a puff and the delivery of the puff.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0046] 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 herein described in detail. It should be understood, however, that the drawings and detailed description of the specific embodiments are not intended to limit the invention to the particular 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]

[0047] Aspects and features of particular examples and embodiments are discussed and described herein. Some aspects and features of particular examples and embodiments may be implemented in a conventional manner, and for the sake of brevity, they will not be discussed or described in detail. Thus, it will 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.

[0048] 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-combustion" aerosol delivery system is one in which the aerosolizable materials that are components of the aerosol delivery system (or its components) are not burned or combusted to facilitate delivery to a user. Throughout the following description, the term "e-cigarette" or "electronic cigarette" may be used, but it will be understood that the term may be used interchangeably for aerosol delivery systems / devices and electronic aerosol delivery systems / devices. Additionally, as is common in the art, the terms "aerosol" and "vapor" and related terms such as "vaporize", "volatilize" and "aerosolize" may generally be used interchangeably.

[0049] In the example of Figure 1, an aerosol delivery system 100 is shown. The aerosol delivery system 100 includes an energy store 120. The energy store 120 has a discharge current of less than 2C. In an embodiment, the energy store 120 may have a discharge current of less than 1C. According to one embodiment, the energy store 120 may have a discharge current of less than 0.5C. In another example, the energy store 120 may have a discharge current of less than 0.4C, less than 0.3C, less than 0.2C, or less than 0.1C.

[0050] It is contemplated that the energy storage 120 may have a discharge current in the range of <0.1C, 0.1-0.2C, 0.2-0.3C, 0.3-0.4C, 0.4-0.5C, 0.5-0.6C, 0.6-0.7C, 0.7-0.8C, 0.8-0.9C, 0.9-1.0C, 1.0-1.1C, 1.1-1.2C, 1.2-1.3C, 1.3-1.4C, 1.4-1.5C, 1.5-1.6C, 1.6-1.7C, 1.7-1.8C, 1.8-1.9C, or 1.9-2.0C.

[0051] A discharge rate of 1C means that the discharge current will discharge the entire energy store in one hour. For example, for an energy store with a capacity of 100 Amp-hours, this corresponds to a discharge current of 100 Amps. A 5C rate for such an energy store is 500 Amps, and a C / 2 rate is 50 Amps.

[0052] The ability to discharge at lower currents can unlock greater battery capacity (mAh) in the same form factor with the same or different chemistry, thereby delivering better battery efficiency factors.

[0053] The energy storage 120 may be a battery, in one example. The energy storage 120 may contain chemical energy that can be converted and delivered as electrical energy. The energy storage of modern systems may place a high level of stress on the electronics of the aerosol delivery system as they attempt to rapidly deliver energy from the energy storage to the aerosol generation mechanism. The energy storage 120 of one embodiment of the presently disclosed aerosol delivery system 100 instead has a discharge current of less than 0.5C. This may reduce stress on the electronics of the aerosol delivery system 100.

[0054] The energy storage 120 described above has lower performance requirements than those required to deliver energy quickly. In this manner, the energy storage 120 may be a lower cost energy storage, thus reducing the cost of the aerosol delivery system 100.

[0055] In the example shown in FIG. 1, the aerosol delivery system 100 includes a housing 110 in which an energy storage device 120 is disposed.

[0056] In the example of FIG. 2, an aerosol delivery system 200 is shown. The aerosol delivery system 200 comprises an energy storage 220. The aerosol delivery system 200 comprises an aerosol generation mechanism 230. The aerosol generation mechanism 230 is for providing an aerosol from an aerosol generation medium. In one example, the aerosol generation mechanism 230 may be a heater 230. The heater 230 may be for providing heat to the aerosol generation medium. The heater 230 may be a resistive heater 230. The energy storage 220 may be arranged to directly deliver energy to the heater 230 for heating. The heater 230 may be an inductive heater or part of an inductive heating system. In an example where the heater 230 is an inductive heater or part of an inductive heating system, the system may have a higher peak current than a resistive heating system.

[0057] The heater 230 may comprise one or more electrical resistance heaters, including, for example, one or more nichrome resistance heater(s) and / or one or more ceramic heater(s). The one or more heaters may comprise one or more induction heaters, which in turn include a structure comprising one or more susceptors that, during use, may form a chamber into which an article containing the aerosolizable material is inserted or otherwise disposed. Alternatively, or in addition, the one or more susceptors may be provided with the aerosolizable material. Other heating structures may also be used.

[0058] Heater 230 may have relatively low performance requirements because it is not supplied with energy from the rapidly heated energy storage 220. In this manner, the cost of heater 230 may be reduced, thereby reducing the cost of aerosol delivery system 200. Heater 230 may be operated at as little as about 3 W.

[0059] The cost of heater 230, or the overall cost of the entire aerosol delivery system 200, may be reduced. Heater 230 may be, for example, a Positive Temperature Coefficient ("PTC") type that self-regulates temperature, which may override some of the software controls currently in use. Reducing the power draw or peak current may provide a wider range of options for battery types, chemistries, etc., and also reduces the overall cost of aerosol delivery system 200.

[0060] The heater 230 may have a high thermal mass. In this regard, the heater 230 may be supplied with energy from the energy storage 220 to provide the aerosol. The heater 230 may retain energy as thermal energy for an extended period of time as a result of the high thermal mass. The high thermal mass prevents the heater 230 from heating up too quickly. The high thermal mass helps the heater 230 to remain hot after it reaches a temperature suitable for generating an aerosol from the aerosol-generating medium.

[0061] High thermal mass, as used herein, may be interpreted to mean that the heater 230 can store about 50 J or more of energy. In one example, the energy store 220 can provide about 3 J / s. Aerosolization can occur with about 60 J of aerosol-generating material, and a puff can have a duration of about 3 seconds. The mass of the heater 230 can provide enough energy to affect a temperature range between about 220° C. and about 280° C.

[0062] As one skilled in the art will appreciate, the term or concept of thermal mass can be defined as the energy stored per unit change in temperature and for a homogeneous material can be calculated by multiplying the mass by the specific heat capacity. Thus, if heater 230 has a mass of 5 grams and is made of steel, its thermal mass is approximately 2 J / °C.

[0063] The energy may be stored in a phase-change material (PCM). The energy may be held at a more constant temperature. The PCM may be provided with a transition temperature near the desired typical operating temperature (e.g., these may be in the range of 220°C to 280°C, or any other suitable range). The PCM may further limit the maximum temperature provided to the aerosol-generating material. This may reduce the adverse effects of high temperatures on taste and toxicity profiles.

[0064] Thus, the high thermal mass heater 230 can reduce the time between a user's indication of a request for a puff and the delivery of the puff. Because the heater 230 is already at operating temperature, the puff can be delivered immediately upon request. Similarly, the high thermal mass heater 230 can eliminate the need for a user to signal an intent to puff, for example, by a button on the housing 210 of the aerosol delivery system 200. Instead, the user can inhale on the system 200 and be delivered an aerosol immediately.

[0065] The heater 230 may be made of a thermally conductive material such as metal or ceramic. In a particular example, the heater 230 is made of alumina. The heater 230 may have a mass of about 5 grams. In a particular example, the heater 230 is made of steel, the heater 230 may have a mass of about 5 grams or so. The dimensions are 700 mm. 3 The shape of the heater 230 may be selected to reduce heat loss from the exterior surface.

[0066] In the example of Figure 3, an aerosol delivery system 300 is shown. The aerosol delivery system 300 shown in Figure 3 includes an aerosol generation medium 340 disposed within a housing 310 of the aerosol delivery system 300. The housing 310 of the aerosol delivery system 300 may include multiple components.

[0067] In the example shown in Figure 3, the system 300 includes a power section 312 and a heater section 314. The power section 312 includes an energy storage 320. The heater section 314 includes a heater 330. In the example of Figure 3, the heater section 314 includes an aerosol generation medium 340 disposed within the heater section 314. The power section 312 and the heater section 314 can be arranged to be removably connectable to each other. In this manner, the aerosol delivery system 300 can be modular. The power section 312 and the heater section 314 can be connected by a push-fit connection, a screw-fit connection, or the like.

[0068] The heater 330 and the energy storage 320 may be connected, such as by a circuit, which may be a complete circuit upon connection of the power section 312 and the heater section 314. Energy may be provided to the heater 330 from the energy storage 320 via the circuit.

[0069] The heater 330 and aerosol-generating medium 340 may be arranged as shown, or in a heater and wick combination. Thus, the aerosol-generating medium 340 may be a liquid that is delivered to the wick and aerosolized by heat from the heater 330. The aerosol-generating medium 340 may be contained in a liquid reservoir or the like. The aerosol-generating mechanism 330 may be part of a cartomizer or the like.

[0070] In Fig. 4, a schematic flow chart of a method for generating an aerosol is shown. The method 400 is shown in four steps 410, 420, 430, 440. The first step 410 involves providing energy to an aerosol generation mechanism. The aerosol generation mechanism may be in the form of a heater. The energy may be provided to the aerosol generation mechanism from an energy storage. The energy storage may be a battery or the like. The energy provided to the aerosol generation mechanism may be sufficient for the mechanism to reach an operating condition, such as an operating temperature, for generating an aerosol from an aerosol generation medium.

[0071] A second step 420 includes providing an aerosol from the aerosol generating medium during a first smoking session. Energy provided to the aerosol generating mechanism may be transferred to the aerosol generating medium such that an aerosol is generated. This aerosol may be inhaled by the user during the first smoking session. The first smoking session may last for example for several puffs, for example 8-12 puffs. The aerosol generated during this second step 420 may be arranged to be provided for up to or at least 12 puffs. In one example, at least one puff should be provided during this step 420. The rate of delivery of energy to the heater to generate the aerosol may be on the order of about 15 J / s. The rate may vary based on the aerosol generating material, which may be e-liquid or tobacco. For gel systems, the rate of delivery of energy to the heater to generate the aerosol may be on the order of about 30 J / s. Aerosol generating materials with a high water content may require a larger energy delivery rate, for example due to the high thermal mass of water.

[0072] A third step 430 involves stopping the supply of energy to the aerosol generating mechanism. This may be the result of the cessation of a smoking session, for example as detected by a puff sensor or the like. Alternatively, the energy store may stop supplying energy to the aerosol generating mechanism once a certain amount of energy has been delivered to the aerosol generating mechanism. The certain amount of energy delivered may be detected by a drop in energy in the energy store or by detecting a characteristic of the aerosol generating mechanism. In an example where the aerosol generating mechanism is a heater, this may be by detecting the heater reaching a certain operating temperature. The operating temperature may be from about 220°C to about 260°C. Such a temperature allows an aerosol to be generated from a medium such as tobacco, nicotine, acid, glycerol, etc. Other temperatures may be used for other media that require or preferentially generate aerosols, at various temperature ranges.

[0073] A fourth step 440 includes providing an aerosol from the aerosol generating medium during a second smoking session. The aerosol generating mechanism holds the energy provided by the energy storage such that an aerosol can be provided from the aerosol generating medium during the second smoking session. The second smoking session follows the first smoking session and occurs after cessation of the energy supply to the aerosol generating mechanism. The second smoking session can occur up to 5 seconds after the first smoking session, up to 10 seconds after the first smoking session, up to 15 seconds after the first smoking session, up to 20 seconds after the first smoking session, up to 25 seconds after the first smoking session, up to 30 seconds after the first smoking session, up to 35 seconds after the first smoking session, up to 50 seconds after the first smoking session, up to 45 seconds after the first smoking session, etc.

[0074] The aerosol generating mechanism may be a heater having a heat transfer coefficient such that energy provided to the heater during a first smoking session is retained to generate aerosol from the aerosol generating medium in a second smoking session. The heater may have a heat capacity or thermal conductivity based on the factors described above. Because the materials used in the heater may vary, the conductivity may vary from about 5 to 400 W / m / K.

[0075] The system allows for greater flexibility in terms of using lower specification energy storage, for example, lower specification energy storage than would be used in a typical system due to the slower delivery of energy from the energy storage, which can reduce the overall cost of the system disclosed herein.

[0076] The aerosol delivery systems disclosed herein can be activated by a user, such as by a push button on the housing of the system, which can provide a signal indicating when the device is in use and when it is not in use, and therefore when to deliver energy to the aerosol generating mechanism. In another embodiment, a puff detector may be used, without the need for a push button.

[0077] 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.

[0078] In some embodiments, the aerosolizable material includes one or more polyhydric alcohols, such as propylene glycol, triethylene glycol, 1,3-butanediol, and glycerin, esters of polyhydric alcohols, such as glycerol, monoacetate, diacetate, or triacetate, and / or aliphatic esters of mono-, di-, or polycarboxylic acids, such as dimethyl dodecanedioate, dimethyl tetradecanedioate, etc.

[0093] Typically, 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, however, it is envisioned that an article that itself comprises a means for powering an aerosol generating component may itself form a non-combustion aerosol delivery system.

[0094] In some embodiments, an article for use with a non-combustion aerosol delivery device may include an aerosolizable material, an aerosol generating component, an aerosol-generating region, a mouthpiece, and / or a region for receiving the aerosolizable material.

[0095] In some embodiments, the aerosol generating component is a heater capable of interacting with the aerosolizable material to release one or more volatile substances from the aerosolizable material to form an aerosol.

[0096] In some embodiments, the substance to be delivered may be an aerosolizable material. An aerosolizable material, sometimes referred to herein as an aerosol-generating material, is a material capable of generating an aerosol when, for example, heated, irradiated, or otherwise energized. The aerosolizable material may be, for example, in the form of a solid, liquid, or gel, and may or may not contain nicotine and / or flavorings. In some embodiments, the aerosolizable material may comprise an "amorphous solid," which may alternatively be referred to as a "monolithic solid" (i.e., non-fibrous). In some embodiments, the amorphous solid may be a dry gel. An amorphous solid is a solid material that can hold some fluid, such as a liquid, within it. In some embodiments, the aerosolizable material may comprise, for example, about 50 wt%, 60 wt%, or 70 wt% of an amorphous solid, up to about 90 wt%, 95 wt%, or 100 wt% of an amorphous solid.

[0097] The amorphous solid may include a colorant. The addition of a colorant can change the visual appearance of the amorphous solid. The presence of a colorant in the amorphous solid enhances the visual appearance of the amorphous solid and the aerosol-forming material. By adding a colorant to the amorphous solid, the amorphous solid can be color-matched to other components of the aerosol-forming material or other components of an article that includes the amorphous solid.

[0098] Depending on the desired color of the amorphous solid, various coloring agents can be used. The color of the amorphous solid may be, for example, white, green, red, purple, blue, brown, or black. Other colors are also contemplated. Natural or synthetic coloring agents, such as natural or synthetic dyes, food grade coloring agents, and pharmaceutical grade coloring agents, may be used. In certain embodiments, the coloring agent is caramel, which may provide the amorphous solid with a brown appearance. In such embodiments, the color of the amorphous solid may be similar to the color of other components in the aerosol-generating material that includes the amorphous solid, such as the tobacco material. In some embodiments, the addition of a coloring agent to the amorphous solid renders the amorphous solid visually indistinguishable from other components in the aerosol-generating material.

[0099] The colorant may be incorporated during the formation of the amorphous solid (e.g., when forming a slurry containing the materials that will form the amorphous solid) or may be applied to the amorphous solid after its formation (e.g., by spraying it onto the amorphous solid).
