Description

[Technical Field]

[0001] (cross reference) This application claims priority to U.S. Provisional Patent Application No. 61 / 524,308, filed August 16, 2011, the entire contents of which are incorporated herein by reference. [Background technology]

[0002] The use of tobacco products and the harmful side effects of smoking continue to attract attention worldwide. With the implementation of numerous regulations regarding smoking in the workplace or in public places, there has been significant interest in developing alternative products. One way to reduce the harmful side effects of smoking is to not burn tobacco products, as many of the harmful analytes obtained from smoking, such as Hoffman analytes, are ingested through the combustion of substances. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] U.S. Application Serial No. 11 / 485,168 [Patent Document 2] U.S. Patent No. 4,819,665 [Patent Document 3] U.S. Patent No. 4,793,365 [Patent Document 4] U.S. Patent No. 5,027,836 [Patent Document 5] International Application No. WO2006 / 082571 Summary of the Invention [Problem to be solved by the invention]

[0004] The challenge of developing and marketing a device capable of delivering aerosolized tobacco products is catering to users in terms of visual and physical appeal for use. A device that can be used multiple times to aerosolize a variety of different substances, while providing users with a sensation similar to that of smoking, such as visible vapor, is desirable. Devices and products that can aerosolize tobacco products and deliver reduced Hoffman analytes and mutagens to users compared to smoking are desirable. [Means for solving the problem]

[0046] The inventions described herein have broad application for the inhalation of active substances, as will be appreciated by those skilled in the art upon review of this disclosure. For example, devices, cartridges (i.e., pods) such as those disclosed in U.S. Application No. 11 / 485,168 (Patent Application 1), systems, kits, and methods can be used, for example, for inhaling tobacco products through the mouth or nose. The devices, systems, kits, and methods can be used to inhale any substance, such as botanicals, medicinal substances, nutritional substances, or any other substance, for example, to provide a benefit or sensation to the end user.

[0047] Provided herein is a device for generating an inhalable aerosol, the device comprising a mouthpiece, a main body, an electronic heater including a heater circuit, an oven, and a printed circuit board within the main body, the electronic heater including an electric heater and a temperature regulator configured to heat a viscous vaporizable material and generate an inhalable aerosol.

[0048] In some embodiments, the tip is separate or integrated into the device, hi some embodiments, the tip is retracted from the device with a push-push mechanism.

[0049] In some embodiments, the heater circuit is soldered to the heater circuit board. In some embodiments, the electronic heater includes a resistive heating element and a thermistor configured to monitor and precisely control the vaporization temperature of the viscous vaporizable material. In some embodiments, the heater circuit is a thin film polyimide heater.

[0050] In some embodiments, the electronic heater is sealed by a hermetic or dust seal.

[0051] In some embodiments, the device includes a magnetic control using a reed or hall effect switch. In some embodiments, the magnetic control using a reed or hall effect switch is integrated into the mouthpiece.

[0052] In some embodiments, the device includes a magnetic lid.

[0053] In some embodiments, the device includes a thermally conductive shell configured to distribute excess heat and maintain a low exposed surface temperature.

[0054] In some embodiments, the device includes a time-based or sensor-based standby mode activation, in some embodiments the sensor includes an accelerometer or other tactile / vibration sensor, a capacitive (touch) sensor, a sensor for monitoring a thermistor configured to detect whether the heater is being worn by a user blowing on the device.

[0055] In some embodiments, the device includes a proportional-integral-derivative (PID) control loop configured to control the operating temperature.

[0056] In some embodiments, the device includes a thin-walled metal heating chamber.

[0057] In other embodiments, the device comprises an aerogel insulator. In some embodiments, the aerogel insulator comprises silica aerogel with reinforcing fibers.

[0058] In some embodiments, the heater is heat pressed, ultrasonically bonded, or overmolded into a high temperature plastic part. In some embodiments, the heater is heat stated or swaged into a high temperature plastic part. In some embodiments, the heater is heat swaged into a high temperature plastic part.

[0059] In some embodiments, the device further includes a magnetic charge connector configured to connect the device to a charger.

[0060] In some embodiments, the device includes a single button interface.

[0061] In some embodiments, the viscous vaporizable material is in a removable pod. In some embodiments, the removable pod comprises particles of the viscous vaporizable material less than about 2 microns in size. In some embodiments, the removable pod comprises a viscous vaporizable material consisting essentially of particles less than about 2 microns in size.

[0062] Provided herein is a device for generating inhalable aerosols, the device including a mouthpiece, a body, an electronic heater within the body configured to heat a viscous vaporizable material and generate an inhalable aerosol, a battery, a temperature regulator, and a single button interface. An exemplary device (100) is illustrated in FIG. 1 , which includes a single button interface (102) for on, off, and wake-up mechanisms, and a heater circuit (105, tail shown) soldered to a PCB (104) and a battery (103) (e.g., a LiPo battery). As shown in FIG. 1 , the outer half (101) of the body snaps together to hold and protect the device. In some examples, the outer body is molded as a single piece. In some embodiments, the single button interface provides mechanisms for turning on, off, and waking from sleep. In other embodiments, additional buttons are included for any of these functions. For example, pressing a single button for one second turns the device on. Holding the button for 5 seconds overrides motion-based low-power standby and automatically powers down. Alternatively, a second button can be used to disable motion-based low-power standby and / or power down. For example, a user can use this override if they do not want the device to cool down while it is placed on a table. In some embodiments, after activation, if a single button is pressed for a very long time (more than 10 seconds), the device powers down again. This is to prevent inadvertent activation, such as in a purse. When on, a momentary press of the button powers down. In some embodiments, the single or multiple buttons can report the remaining battery level (e.g., via blinking LEDs), change the device's operating temperature, or change the nominal intensity of the LEDs if the user is in a dark environment and does not want to be distracted by light. These various features can be triggered by one or more buttons or the same button, by a prescribed press time or number of times, by pressing one or more buttons or the same button.

[0063] As described herein, an electronic heater includes a heater circuit, an oven, and a printed circuit board to heat a viscous vaporizable material to generate an inhalable aerosol. The heater circuit may be flexible. In some embodiments, flexible heater circuits are typically etched from polyimide films coated with copper or constantan. In some embodiments, flexible heaters are constructed by die-cutting thin sheets of constantan or copper. In this case, the heater circuit must be electrically isolated from adjacent conductive elements in the assembly using polyimide or other suitable insulators that are stable at high temperatures. The heater circuit heats the attached oven, which in turn heats the cartridge or active material by thermal conduction. A resistive heater circuit heats when current passes through it. Heat is then transferred from the circuit to the oven walls. Thermal conduction continues from the oven walls to the cartridge or active material. Note that while heat can be transferred from the oven walls to the active material or cartridge by convection and radiation, most transfer occurs by conduction.

[0064] In some embodiments, the device includes one or more button interfaces for on, off, and wake-from-sleep mechanisms, and a heater circuit soldered to the PCB.

[0065] Provided herein is a device for generating inhalable aerosols, the device including a mouthpiece, a body, an electronic heater within the body configured to heat a viscous vaporizable material and generate an inhalable aerosol; a battery, a temperature regulator, and a time- or sensor-based standby activation configured to conserve battery power. In some embodiments, the device includes a time- or sensor-based standby activation to conserve battery power. This may also / alternatively be referred to as standby mode. Standby mode may also / alternatively be referred to as sleep mode. After non-use based on time, movement or lack of movement, orientation (e.g., vertical), or placement on a charging base, or any combination thereof, the device is programmed to switch to sleep mode (standby mode) to conserve at least battery power. The device may be woken from this standby or sleep mode by a change in movement (e.g., from vertical to horizontal, horizontal to vertical, or a movement indicating the user has picked up the device), removal from the charging base, user touch, the user blowing on the device, or activation by pressing any button on the device (or any combination thereof). After an extended period in standby mode, the device powers down and can be turned off and / or turned back on by the user pressing a button on the device, or in some embodiments, by the user blowing on the device. In such embodiments, simply moving the device or removing it from the charging base will not activate the device once it has powered down. In other embodiments, moving the device or removing it from the charging base will turn the device on from an off state or standby mode.

[0066] In some embodiments, standby mode conserves battery power by lowering the device's regulated temperature. For example, regardless of whether the user puffs on the device, the majority of the heat generated by the device is lost to the environment. Therefore, maximizing the time the device spends in standby and minimizing its internal temperature while in standby conserves power. However, when the device awakens from standby, it is desirable for the device to return to its primary operating temperature as quickly as possible to give the user the impression that their smoking experience is uninterrupted. Therefore, a balanced condition must be established. For example, in current electronic cartridge-based devices, the primary operating temperature is 165°C and the standby temperature is 150°C. This temperature difference is small enough that when a user activates the device from standby, by the time the user begins smoking, the heater has had enough time to increase its temperature and the user perceives little or no interruption in vapor production. In some embodiments, the temperature difference is set to be 30°C, 25°C, 20°C, 15°C, 10°C, or 5°C between the primary operating temperature and the standby temperature. In some embodiments, the temperature differential is set to be anywhere from 30°C to 5°C between the main operating temperature and the standby temperature.

[0067] In other embodiments, the battery is a disposable battery. In other embodiments, the battery is a rechargeable battery. In certain embodiments, the rechargeable battery is lead-acid, nickel-cadmium (NiCd), nickel-metal hydride (NiMH), lithium ion (Li-ion), lithium ion polymer (Li-ion polymer or LiPo), or the like.

[0068] A rechargeable battery, storage battery, or accumulator is a type of battery. A battery contains one or more electrochemical cells and is a type of energy storage device. It is known as a secondary battery because its electrochemical reaction is electrically reversible. Rechargeable batteries come in many different shapes and sizes, ranging from button cells to megawatt systems connected to stabilize the electrical grid. Several different combinations of chemistries are commonly used, including lead-acid, nickel-cadmium (NiCd), nickel-metal hydride (NiMH), lithium-ion (Li-ion), and lithium-ion polymer (Li-ion polymer, Li-poly, Li-pol, Lipo, LIP, PLI, or Lip).

[0069] The device can generate a temperature high enough to aerosolize a product contained within the device. A typical device can include a mouthpiece and a main body having a heater, an oven chamber, a LiPo battery, and a controller for maintaining the operating temperature. A user-selected temperature can be used as an input to the system, as described above. In some embodiments, the temperature can be preset. An example of a device operating temperature regulator includes a bimetallic actuator. Alternatively, the system can be used to measure the current temperature, for example, with a thermocouple sensor to compare the current temperature to a predetermined temperature, and for example, with a microcontroller to control an electrochemical valve (e.g., a servo valve or a solenoid valve). A user-selected temperature can be used as an input to the system, as described above. Typically, the device's operating temperature is no more than 200°C.

[0070] A device for generating an inhalable aerosol is provided herein, comprising a mouthpiece, a body, an electronic heater within the body configured to heat a viscous vaporizable material to generate an inhalable aerosol; a battery; a temperature regulator; and a temperature control loop. In certain embodiments, a heater is provided that includes a thermistor element soldered to the control loop. In certain embodiments, the device includes a PID (proportional-integral-derivative) control loop to control the operating temperature. The control loop serves to precisely adjust a desired setpoint temperature for the device. Depending on the device design and application, the setpoint temperature is fixed in some embodiments, while in other embodiments, the setpoint temperature is user-selectable. The setpoint may change dramatically during device operation. For example, in standby mode, the setpoint is reduced by a specific amount. In some embodiments, the input for the control loop is typically a thermistor located on or adjacent to the heater circuit. This thermistor is connected to a microcontroller, which performs an A / D measurement and uses the resulting value to calculate the PID control variable. The control variable then sets the duty cycle (and resulting power output) of the heater circuit.

[0071] Provided herein is a device for generating an inhalable aerosol, the device including a mouthpiece, a body, an electronic heater including a heater circuit within the body configured to heat a viscous vaporizable material and generate an inhalable aerosol, and a temperature regulator, the heater circuit having low resistance so that a single battery can operate the device. In some embodiments, the heater circuit has low resistance so that a single battery may be used to operate the device. In some embodiments, the resistance of the heater circuit is selected so that the output of the heater circuit is high enough to reach a predetermined operating temperature within an acceptable heating time and to withstand the load on the system from a user puffing on the device. An approximation is provided by the following relationship: R=V^2 / P, where V is the battery voltage under load, P is the desired wattage of the heater, and R is the heater circuit resistance.

[0072] A device for generating inhalable aerosols is provided herein, including a mouthpiece, a body, an electronic heater within the body configured to heat a viscous vaporizable material and generate an inhalable aerosol; a battery; and a temperature regulator, the electronic heater sealed by a hermetic or dust seal. As shown in FIG. 2 , an exemplary device (200) includes a thin-walled stainless steel tube (210) that pierces the sealed lid of a capsule (i.e., a pod). The thin-walled stainless steel tube (210) within the exemplary device (e.g., a metallic "oven") is heat-pressed (e.g., heat-staked or heat-swaged), ultrasonically bonded, or overmolded into a high-temperature-compatible plastic part. This process forms a hermetic or dust seal (240) that prevents ambient dust from entering the device's internal chamber and prevents dust from the internal insulating material from exiting the device or entering the heated chamber. The plastic part may comprise any thermoplastic material that provides high temperature stability. In some embodiments, the plastic portion comprises polyphenylene sulfide (PPS (trade name Ryton)), polyetherimide (PEI (trade name Ultem)), liquid crystal polymer (LCP), or the like. In a specific embodiment, the plastic portion is PPS. PPS is used because of its generally excellent moldability.

[0073] In some embodiments, the oven is heat-staked or heat-swaged into a high-temperature plastic part. As referred to herein, heat staking forms material all around the perimeter of the mating edge. Heat staking creates several thermoplastic posts that are inserted through holes in the formed metal oven, and the posts are heated to form a type of "rivet." In certain embodiments, the oven is heat-swaged into a high-temperature plastic part. In some embodiments, the oven is bonded to the plastic part using an adhesive. In certain embodiments, the adhesive is stable at high temperatures so that it does not soften or off-gas. In some embodiments, the oven is connected to the plastic part by a mechanical mechanism, such as a crimp threaded connection, a press fit, or the like. For any mechanical bond, in some embodiments, an O-ring is used between the two parts to ensure a dust seal is formed. It is important to minimize heat transfer at this joint because much of the heat is transferred to the external casing of the device (and thus lost to the environment) in this manner.

[0074] Provided herein is a device for generating an inhalable aerosol, the device including a mouthpiece, a body, an electronic heater within the body configured to heat a viscous vaporizable material and generate an inhalable aerosol; a temperature regulator, and an aerogel insulator. In some embodiments, the aerogel insulator is an aerogel blanket. In some embodiments, the device includes an insulating chamber (220) containing an aerogel blanket (not shown in FIG. 2; see FIG. 5) to maintain efficiency and low exposed surface temperatures. In some embodiments, the aerogel may be a silica aerogel with reinforcing fibers (e.g., Pyrogel 2250 flexible aerogel blanket).

[0075] As used herein, the term "aerogel" refers to a synthetic porous material derived from a gel in which the liquid component of the gel has been replaced with a gas. The result is a solid with very low density and low thermal conductivity. Aerogels are excellent thermal insulators because they virtually eliminate the three methods of heat transfer (convection, conduction, and radiation). Because aerogels are composed almost entirely of gas, and gas is a very poor thermal conductor, aerogels are excellent conductive insulators. Silica aerogels are particularly excellent because silica is also a poor thermal conductor (metallic aerogels, on the other hand, are not as effective). Aerogels are excellent convection inhibitors because air cannot circulate through the lattice. Silica aerogel is the most common type of aerogel and the most extensively studied and used. It is a silica-based material derived from silica gel. Carbon aerogels are composed of particles with sizes in the nanometer range that are covalently bonded together. It has a very high porosity (over 50%, with pore diameters less than 100 nm) and a surface area ranging between 400-1,000 m2 / g. Aerogels made with aluminum oxide are known as alumina aerogels. These aerogels are used as catalysts, especially when "doped" with metals different from Al. Nickel-alumina aerogel is the most common combination.

[0076] In some embodiments, the device includes two magnets (230) (e.g., gold-plated rare earth magnets) that serve as both a mechanical attachment and a battery charging conduit (not shown) to the charging base. The magnets must be strong enough to hold the device in place in the charging base. In some embodiments, the magnets include NdFeB, grade N42. In some embodiments, the magnets have a surface field of 6128 Gauss. The pod (270) is inserted into an oven with a polyimide thin film heater and a thermistor applied to its exterior. The polyimide thin film heater is composed of a thin, high-dielectric, lightweight organic polymer film that offers exceptional tensile strength, tear resistance, and dimensional stability.

[0077] Thus, provided herein is a device for generating an inhalable aerosol, the device comprising a mouthpiece, a main body, an electronic heater within the main body configured to heat a viscous vaporizable material and generate an inhalable aerosol, a temperature regulator, and a magnetic charge connector.

[0078] In some embodiments, the battery used in the device is a single cell LiPo battery (e.g., an 18-650 size, 2600 mAh lithium-ion monolithic cell or a 14-650 size, 940 mAh lithium-ion monolithic cell) for repeated use of the device. In some embodiments, the battery used in the device is an 18-650 size, 2600 mAh, or 14-650 size, 940 mAh, or other suitable rechargeable battery. The device can be used for up to 10, 20, 30, 40, 50, 60, or more applications (depending on which size rechargeable battery is used). In some embodiments, the device can be used for 60 or more applications. The device can also be used for up to 1, 2, 3, 4, 5, 6, 7, or 8 hours or more of continuous or non-continuous use. Cartridges for use with the device can be disposed of after each use or can be used for multiple applications. The long-lasting use of the device provides the user with the advantage of not having to repair the device or periodically charge the battery.

[0079] Typically, the operating temperature of the device is no more than 200°C. In many cases, the temperature required to aerosolize the product is between about 100-200°C. In some embodiments, the temperature required to aerosolize the product is about 150°C. Once the product within the device is aerosolized, the aerosolized product is delivered to the user through the mouthpiece. In many cases, the typical device is designed to model smoking devices such as cigarettes, pipes, or cigar pipes.

[0080] In Figure 3, an exemplary device (300) includes a split-off tip (310) design, with one half removable and conforming to the contours of the device. In some embodiments, the tip is attached to the body with a rare earth magnet. In some embodiments, the tip is attached to the body with a plastic detent or other mechanism.

[0081] Provided herein is a device for generating inhalable aerosols, the device including a mouthpiece, a body, an electronic heater within the body configured to heat a viscous vaporizable material and generate an inhalable aerosol; and a temperature regulator, the mouthpiece being integrated into the device. In some embodiments, the mouthpiece is integrated into the device with a hinge or other mechanism (such as a string). In certain embodiments, the mouthpiece rotates or slides to expose the heating chamber. In certain embodiments, the mouthpiece completely detaches from the attachment mechanism for cleaning or replacement but reattaches to the device ("removably captured"). In some embodiments, the device further includes magnetic contacts (312) and a tactile button with an LED-illuminated "halo" indicator. The indicator reports information about the device's status. In some embodiments, a sawtooth pattern indicates that the device is hot. In some embodiments, a solid pattern indicates that the setpoint temperature has been reached and the user can puff on the device. If the battery is very low, in some embodiments, the LED indicator flashes multiple times (e.g., five times) and then the device powers off. In some embodiments, a motion sensor detects this while shaking the device, and the LED indicates the current battery level. For example, it flashes three times when fully charged, two times when partially charged, and one time when low. The device then resumes normal operation. When the device is placed on the charging base, in some embodiments, a sawtooth pattern indicates that it is currently charging. In certain embodiments, the LED becomes solid when charging is complete. In some embodiments, error conditions can also be reported. If an internal fault is measured, the indicator flashes ten times and the device powers off on its own.

[0082] In some embodiments, the device includes a removable tipping member to which a removable pod can be attached and / or inserted. The tipping member is removed with a quarter turn to expose the removable pod. The removable pod contains tobacco and / or other plant products used to generate an inhalable aerosol. The pod, in some embodiments, contains particles less than about 2 microns in diameter. In some embodiments, a vaporization device is provided for use with sticky vaporizable materials, such as loose tobacco and other plant products (without the pod).

[0083] Figure 4 demonstrates an exemplary device (400) with a tip (410) that retracts from the device with a push-push mechanism. This powers the device via a magnet embedded in the tip and a Hall Effect sensor on the PCB. The device includes an LED indicator (460) (or the like) and a single-piece extruded aluminum exterior body. In some embodiments, the LED indicator is tri-color (RGB). In some embodiments, the LED indicator displays multiple colors. For example, when heating, the indicator glows purple. Once the setpoint temperature is reached, the indicator glows green. When in standby, it glows blue. When the device is shaken, the battery indicator flashes three times, and the color determines the charge level: green for full charge, yellow for partial charge, and red for low charge. When the tip is completely removed from the device, the device immediately stops heating, and the LED indicates the current user-selectable temperature setting: red for high, orange for medium, and yellow for low. Pressing the "temperature setting button," exposed by removing the tip, cycles through the firmware's temperature settings, and the new setting is reflected by the LED. Reinserting the tip returns the device to normal heating operation. While charging, the LED is solid orange. Once charging is complete, the LED becomes solid green. As with other embodiments, the LED can report error conditions by flashing and / or by flashing a distinctive color. These colors may be changed to any color in accordance with the practice of the present invention.

[0084] In some embodiments, the device includes a mouthpiece that retracts from the device with a push-push mechanism. In some embodiments, the push-push mechanism also turns on the device with a magnet embedded in the mouthpiece and a Hall effect sensor on the PCB (printed circuit board). Those skilled in the art will readily recognize other suitable mechanisms for turning on the device with an appropriate sensor.

[0085] Provided herein is a device for generating inhalable aerosols, the device comprising a mouthpiece, a body, an electronic heater within the body configured to heat a viscous vaporizable material and generate an inhalable aerosol; and a temperature regulator and a push-push mechanism configured to toggle the mouthpiece between a retracted position and an "on" position. An internal view of the exemplary device of FIG. 4 is shown in FIG. 5. In such an embodiment including the push-push mechanism, the device includes a vaporization chamber lid (576) (opposite the mouthpiece (510)). The device includes a deep-drawn stainless steel heating chamber (524) ("oven") to which a polyimide thin-film circuit heater is applied. The push-push mechanism for retracting the mouthpiece consists of a compression spring (513), a leaf spring (512), and a stainless steel tube (511) attached to the mouthpiece (510), along with a catch groove (534) and a toggle slider (509). A reed switch / Hall Effect sensor (533) is incorporated to detect whether the tip is inserted (the device is inoperative). To extend the tip to the "on" position, the user presses the tip (510). Because the tip is attached to the tube (511), this action compresses the compression spring (513). This action moves the leaf spring (512) away from the axis of the tube and onto the outer diameter of the toggle slider (509). When the user then releases the tip, the compression spring pushes the tip and tube subassembly outward from the device. The sloped flaps of the leaf spring catch on the toggle slider, causing the slider to move up the tube until it reaches a shoulder on the tube. At this point, the tip continues to extend from the device, with the leaf spring now rubbing against the toggle slider and following the shoulder on the outer diameter of the tube, which is of equal diameter and therefore offers no resistance. The tip rests in the extended "on" position when the catch groove in the tube intersects with the leaf spring cap. A push-push mechanism is used to move the tip from the "on" position to the retracted position.The push-push mechanism is thus configured to toggle the tip between an "on" position, or an extended position in which the tip extends from the body of the device, and a retracted position. In some embodiments, in the retracted position, the tip is completely within the body of the device. In some embodiments, in the retracted position, the tip is completely within the body of the device but is exposed at the open end of the device. In some embodiments, in the retracted position, the tip is substantially within the body of the device, such that a portion of the tip extends beyond the end of the body of the device.

[0086] Many devices use a temperature control scheme in which a temperature controller (bimetallic disc or other controller) is placed in close proximity to the temperature-critical area (as in an oven). See the temperature selection button (535), PCB (504), O-ring seal (526) to control potential aerogel dust, and insulating chamber (525) containing the aerogel blanket. Related techniques typically place temperature-sensitive components in the flow valve, which can be easily affected by cold, expanding fuel gas and is in minimally close contact with the vaporization chamber. Examples of related devices and methods are described in U.S. Patent Application No. 11 / 485,168 (Patent Application 1), U.S. Patent No. 4,819,665 (Patent Application 2), U.S. Patent No. 4,793,365 (Patent Application 3), U.S. Patent No. 5,027,836 (Patent Application 4), and International Application WO 2006 / 082571 (Patent Application 5). A typical device regulation scheme may be to simply twist a switch on an oven to tune to a particular temperature.

[0087] Provided herein is a device for generating an inhalable aerosol, the device including a mouthpiece, a body, an electronic heater within the body configured to heat a viscous vaporizable material and generate an inhalable aerosol; a temperature regulator, and a button-activated temperature selector with a visual, audio, and / or vibration indicator. In some embodiments, the device includes a button-activated temperature selector with a visual, audio, and / or other sensory output (e.g., vibration). In some embodiments, a tactile (mechanical) switch is used as an input to a microcontroller, which, via its software, indicates the change to the user (e.g., via a visual LED, an audio LED, vibration, etc.) and changes the setpoint temperature of the device. The switch may be capacitive, resistive, etc.

[0088] In some embodiments, the vaporization device includes a thin-walled metal heating chamber (or oven chamber). The thin walls allow for low thermal mass and therefore fast start-up. When the device uses viscous vaporizable material directly without including such walls in a pod (or cartridge), the terms "heating chamber," "oven chamber," and "vaporization chamber" are used interchangeably. For devices that include a pod or cartridge, the terms "heating chamber" or "oven chamber" are used interchangeably.

[0089] A device for generating inhalable aerosols is provided herein, comprising a mouthpiece, a body, a vaporization chamber; an electronic heater within the body configured to heat a viscous vaporizable material and generate an inhalable aerosol; a temperature regulator; and a magnetic lid configured to cover the vaporization chamber. The exemplary device (600) in Figure 6 shows an exemplary magnetically attached vaporization chamber lid (676). The lid (676) is nominally completely recessed into the body of the device to prevent inadvertent removal of the lid in a user's pocket, purse, etc. To remove the lid, a user presses a finger against one side of the oval-shaped lid. The underside of the lid is chamfered, allowing the opposite side of the lid to rotate and lift on an axis. Two rare-earth magnets are recessed into either side of the lid along their short axes. Two mating magnets are recessed into the body of the device at corresponding points. These magnets form a "hinge" around which the lid can rotate. Once the lid is rotated, it is relatively easy to overcome the magnetic force and remove the lid completely, thereby allowing access to the vaporization chamber. In some embodiments, the lid of the vaporization chamber is attached by other mechanisms, such as a screw-type, snap-type, or the like. Thus, in some embodiments, the device includes a tilted lid that uses a magnetic or snap attachment to hold the lid in its closed position to prevent accidental opening. Provided herein is a device for generating inhalable aerosols, the device including a mouthpiece, a body, an electronic heater within the body configured to heat a viscous vaporizable material and generate an inhalable aerosol; a temperature regulator, and a tilted lid including a magnetic or snap attachment configured to maintain the lid in its closed position and / or to prevent accidental opening of the lid.

[0090] Those skilled in the art will readily use an energy source to charge the battery. For example, FIG. 7 shows a USB charger (724) with a USB charging cable (734). In some embodiments, the energy source is a wall charger. In some embodiments, the energy source is a car charger. In some embodiments, the energy source is a mobile charger. In particular embodiments, the energy source includes a solar-powered charger, a wind-powered charger, or other green energy-based charger.

[0091] In some embodiments, the device includes a thermally conductive shell to distribute excess heat and maintain a low exposed surface temperature, hi some embodiments, the thermally conductive shell is made from a material with a low specific heat but high thermal conductivity. In some embodiments, the configuration of the material within the thermally conductive shell is such that the temperature of the shell remains below 140° F., below 130° F., below 120° F., below 110° F., below 100° F., 140° F. or less, 130° F. or less, 120° F. or less, 110° F. or less, 100° F. or less, 98.6° F. or less, 90° F. or less, below room temperature, below about 140° F., below about 140° F., below about 130° F. or less, about 120° F. or less, about 110° F. or less, below about 100° F., below the temperature that would burn skin for 2 seconds, below the temperature that would burn skin for 5 seconds, below the temperature that would burn skin for 10 seconds, and / or about room temperature. This combination means that heat is readily dispersed, but there is not enough heat to be absorbed by the hand when gripped. In some embodiments, the thermally conductive shell is made of aluminum, etc. Provided herein is a device for generating an inhalable aerosol, the device including a mouthpiece, a body, an electronic heater within the body configured to heat a viscous vaporizable material to generate an inhalable aerosol, a thermally conductive shell configured to distribute excess heat and maintain a low exposed surface temperature, and a temperature regulator.

[0092] An internal view of a typical device charged by a USB charger is shown in Figure 8. The device includes a charger base (827) (typical of a USB charger) that includes a rare earth magnetic charge-based interface (824). The battery (803) (e.g., a Li-ion battery) is charged with the help of a flexible PCB (804) that runs down to contact the battery terminals. Also shown are a button (802), an accelerometer (816), aerogel (814), and a thermistor (815) for monitoring and precisely controlling the vaporization temperature. The mouthpiece is attached to the body at points (844) and (845). Various mouthpiece embodiments described herein or known to those skilled in the art may be used.

[0093] Any material that can be aerosolized and inhaled by a user may be incorporated into a device or cartridge of the present invention, as will be apparent to those skilled in the art. It is particularly interesting for the material to provide an experience to the user, either in terms of a tactile response within the respiratory tract or visual feedback regarding the release of the inhaled material. For example, many materials are contemplated for use with the present invention, including, but not limited to, tobacco, natural or artificial flavorings, coffee grounds or beans, mint, chamomile, lemon, honey, tea leaves, cocoa, and other non-tobacco alternatives based on other botanical products. The device or cartridge of the present invention may be suitable for use with pharmaceutical or synthetic compounds, for either medicinal or recreational purposes. Any compound that can be vaporized (or volatilized) at relatively low temperatures and without harmful decomposition products is suitable for use with the cartridge or device of the present invention. Examples of compounds include, but are not limited to, menthol, caffeine, taurine, and nicotine.

[0094] The active ingredients contained in the plant products vaporize at various temperatures. The device can be adjusted to establish a single stable temperature, for example, for the purpose of vaporizing a specific product. A controller can also be used to select various temperature settings. The user determines which setting is used based on the type of cartridge. The controller can also affect the desired temperature mechanically, such as by changing the flow rate of a valve, or electrically, such as by using an electromechanical valve and a microcontroller intermediary. For example, to change the operating temperature of the device of the present invention, the oven chamber can be moved relative to a temperature regulator, such as a bimetallic disk.

[0095] Here, tobacco or tobacco material is defined as any combination of natural and synthetic materials that can be vaporized for recreational or medicinal use. In one embodiment of the present invention, the cartridge can be prepared using dried tobacco, glycerin, and flavorings. Those skilled in the tobacco product manufacturing industry are familiar with these and other ingredients used in cigarettes, cigars, and the like. The cartridge can be made by chopping the tobacco (e.g., to a diameter of less than 2 mm, preferably less than 1 mm), adding other ingredients, and mixing until a uniform consistency is achieved. In another embodiment, the cartridge can be prepared by processing the fill material to a paste-like consistency (e.g., particle size less than 1 mm), which facilitates filling the cartridge, for example, by using an auger filler, a peristaltic pump, or a piston pump.

[0096] Preferably, materials for use with devices of the invention or contained within cartridges of the invention include at least one of a vapor-forming medium and a medium that provides a tactile response in the user's respiratory tract. The product aerosolized from materials inserted into the device may be a combination of gas phase gas and droplets that condense from the gas phase and remain suspended in the gas / air mixture (the latter making up the visible portion of the inhaled substance).

[0097] Propylene glycol (PG), glycerin, or a combination of both can be used as the vapor-forming medium. Other vapor-forming media can be used with the cartridges and devices of the present invention. The vapor-forming medium serves to generate a visible vapor, such as a smoke-like vapor, when heated. This vapor can be visualized before inhalation and during evaporation of the medium. PG offers several advantages over glycerin alone, as PG exhibits a much higher vapor pressure at comparable temperatures, allowing the device to operate at lower temperatures. Reducing the operating temperature conserves energy, potentially further improving the health benefits of using this system.

[0098] Surrounding insulating features protect the user from contact with hot internal elements. A typical device may include an insulator that prevents the user from necessarily touching hot portions of the device. Greater thermal insulation is preferable so that the device operates with the greatest possible efficiency, while a key aspect for the user is the perception of a relatively cool surface temperature. Various strategies can be used to address the user's perception of the device's temperature. The device may be wrapped in an insulating material that is durable enough for external use. Materials for this purpose have low thermal conductivity and low heat capacity (specific heat). This combination of properties ensures that little heat is transferred to the user's fingers. Examples of materials with low thermal conductivity and low heat capacity include some polymers and ceramics. A separate strategy is to use an insulating feature that prevents the user from directly touching hot areas. This can minimize the contact area between the user's fingers and the device to further reduce the perceived heat. The thermal conductivity and specific heat of the insulating feature should be as low as possible.

[0099] While preferred embodiments of the present invention have been shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Many modifications, changes, and substitutions will occur to those skilled in the art without departing from the invention. It will be understood that various alternatives to the embodiments of the invention described herein may be employed in practicing the invention. It is intended that the following claims define the scope of the invention and that methods and structures within the scope of these claims and their equivalents be covered thereby.
