Description

CROSS-REFERENCE

This application claims the benefit of U.S. Provisional Patent Application No. 62/815,929, filed on Mar. 8, 2019, the contents of which are incorporated herein in their entirety.

TECHNICAL FIELD

The present invention relates to personal inhalation devices or vaporizers, and more specifically to inhalation devices configured for dabbing use.

BACKGROUND

With the recent growth in vaping and the legalization of certain cannabis-based products, the demand for personal inhalation devices that can deliver vaporized cannabis and other plant-based substances or herbs has risen dramatically, for both medicinal and non-medical purposes. Such devices are typically portable, self-contained devices that come in varying sizes and/or forms, including, for example, slim cylindrical “vape pens” designed to look and feel like a traditional pen, elongated rectangular housings designed to fit easily within a pocket, wide rectangular or square-shaped housings designed to fit comfortably within a hand, vaporizers that look and operate like traditional, medicinal inhalers, rigs or other dabbing devices designed for use with oil or wax substances, as well as many others.
One type of inhalation device is the vaporizer, or vape, which electrically heats a substance into a vapor upon activation and delivers the vapor through a mouthpiece for inhalation. A typical vaporizer includes: (1) a storage compartment for holding a substance to be vaporized, (2) an atomizer or other heating element for vaporizing the liquid, (3) a power source, such as, for example, a rechargeable lithium-ion battery, for powering the atomizer and/or delivery system, and (4) a mouthpiece to enable inhalation of the vapor. When power is applied to the heating element, the heating element fires or activates to aerosolize or vaporize the substance, which may be in direct or indirect contact with the heating element. Suction pressure is supplied by the user at the mouthpiece, to pull the vaporized substance or aerosol through a barrel or delivery tube and out through the mouthpiece.
In most vaporizers, the storage compartment, heating element, and mouthpiece are assembled into a single, smaller unit, known as a cartridge, pod, or other substance delivery component, while the power source is housed in a larger unit that also includes a receptacle for receiving the substance delivery component and for electrically coupling the power source thereto. The larger unit (also referred to herein as “an electronics device”) further includes electronics to control or supply power to the heating element of the cartridge. For example, some existing vaporizers activate the heating element in response to user selection of a power button or other input device. A number of existing vaporizers have multiple heat settings (e.g., high, medium, and low) to control the amount of heat supplied to the substance by the heating element. Many existing vaporizers are configured for use with any compatible cartridge, pod, or other substance delivery component, regardless of the type of heating element (e.g., coil or ceramic) used or the type of substance (e.g., liquid solution, dry herb, or solid compound) stored in the storage compartment. A cartridge may be considered “compatible” so long as it fits inside the receptacle of the electronics device and can be electrically coupled thereto for delivering power to the heating element of the cartridge.
Dabbing is an increasingly popular form of vaping that involves a sticky oil or wax comprising a very high concentration of cannabis, including THC, CBD, and/or other cannabinoid. Also referred to as shatter, budder, and butane hash oil (BHO), dabs are heated on a hot surface, typically a nail head fired by a blow torch, and the resulting vapor is inhaled, usually through the glass tube of a dab rig. Dabs are typically stored in a small concentrate jar and scooped out using a metal tool and placed on the nail head just prior to use. Dab concentrates are quite messy to handle, making it difficult to keep the nail head and tool clean or mess-free. Another drawback of traditional dabbing is that the dab rigs are not especially portable or convenient to use for several reasons, including the need to use a blow torch.
Recently, cartridges and vaporizers configured for use with dabbing have been developed. FIGS. 1A-1C illustrate an existing vaporizer 10 comprising a dab cartridge 12 and an electronic device 14 configured to receive the dab cartridge 12 therein. The electronic device 14 can also be used with other types of compatible cartridges, including oil cartridges, dry herb cartridges, or other non-dab cartridges. The electronic device 14 (also referred to herein as a “power source”) includes a battery (not shown), a receptacle 16 configured to receive, and electrically couple to, a compatible cartridge, and an activation button 18 for controlling or powering the cartridge placed in the receptacle 16. The user presses the activation button 18 to pre-heat the dab cartridge 12, or other cartridge coupled to the electronics device 14. In response, the battery supplies power to the dab cartridge 12, which activates a heating element within the dab cartridge 12. The electronics device 14 also includes a light indicator 20 to notify the user when the cartridge 12 is ready for vaping use, or when the heating element is sufficiently heated to vaporize the dab concentrate.
FIGS. 2A-2C illustrate the mechanics of how to use the existing dab cartridge 12 for dabbing. As shown in FIG. 2A, the dab cartridge 12 includes three components: a top portion 22 comprising a mouthpiece 24 and a tool 26 for handling the dab concentrate, a middle portion 28 comprising a hollow tube or barrel configured to allow vapor to travel up towards the mouthpiece 24, and a base portion 30 comprising a heating element 32 housed within a chamber 34 and configured to heat a dab placed thereon. A bottom of the base portion 30 includes an electronic connector 36 configured to electrically couple the cartridge 12 to the electronics device 14, or the battery therein. The three components are removably coupled together, so that the assembled form shown in FIG. 1B can be inserted into the electronics device 14, as shown in FIG. 1A, and the disassembled form shown in FIG. 2A can be used to prepare the cartridge 12 for use, as shown in FIG. 2C.
In particular, during use, the mouthpiece 24 of the top portion 22 serves as a handle for using the tool 26 to scoop concentrate out of ajar or other storage location and place it directly on the heating element 32 of the base portion 30, as shown in FIG. 2C. The top portion 22 and the base portion 30 are then re-coupled to opposing ends of the middle portion 28, and the assembled cartridge 12 is placed into the electronics device 14. As shown in FIG. 2B, the heating element 32 includes an exposed metal coil that is configured to heat dab concentrate that is in direct contact with the coil. As the dab concentrate heats up, it melts over the coil, flows into the chamber 34, and eventually vaporizes when the heating temperature is sufficiently high. When the user inhales through the mouthpiece 24, the vapor travels from the base portion 30, through the middle portion 28 (or chimney), and out through an opening on top of the mouthpiece 24. The top portion 22 also includes apertures 38 to enable airflow between the mouthpiece 24 and the chimney 28, which allows the vapor to travel into the mouthpiece 24.
Due to the sticky nature of most dab concentrates, a residue 40 forms on the heating element 32 and the tool 26 after just one use, and becomes increasingly messier with each consecutive use. Residue 40 also builds up on the walls of the chamber 34 when dab concentrate misses the coil, becomes stuck to the side walls, or is otherwise out of reach from the heating element 32, and therefore, does not become vaporized. In addition, residue 40 can build up on the outer rim of the base portion 30, particularly when users utilize the chamber walls to scrape concentrate off of the tool 26. Concentrate residue is not only messy, but can interfere with future uses, particularly when the same cartridge 12 is being used with different types of dab concentrates (e.g., different concentration levels, ingredients, chemical properties, flavors, effects, etc.), thus resulting in potentially undesirable combinations or experiences.
Another drawback of existing dab cartridges is that there are no indicators or tools to help the user accurately and consistently measure the amount of concentrate that constitutes one dose. In some cases, the amount that constitutes one dose varies depending on the properties of the dab concentrate, such as, e.g., the particular strain, chemical makeup, ingredients, cannabis concentration level, etc. The amount of concentrate used during a given vaping session can also vary depending on the user's preference and/or experience level. For example, some users may prefer to use a larger dose for a more potent hit, while other users may prefer a lighter dose. On the other hand, inexperienced users may inadvertently use too much or too little without the tools to ensure accurate and consistent dosing. As a result, existing dab cartridges may lead to unintended abuse or misuse of dab concentrates, as well as unpleasant, unwanted, and/or ineffective dabbing.

DETAILED DESCRIPTION

The description that follows describes, illustrates and exemplifies one or more particular embodiments of the present invention in accordance with its principles. This description is not provided to limit the invention to the embodiments described herein, but rather to explain and teach the principles of the invention in such a way to enable one of ordinary skill in the art to understand these principles and, with that understanding, be able to apply them to practice not only the embodiments described herein, but also other embodiments that may come to mind in accordance with these principles. The scope of the present invention is intended to cover all such embodiments that may fall within the scope of the appended claims, either literally or under the doctrine of equivalents.
The term “substance delivery component” is used herein to denote any type of device that includes a storage compartment for holding a substance to be vaporized and a heating element for heating the substance, and is configured for electrical coupling to an electronic inhalation device or other, separate power source (e.g., via USB connection). Exemplary substance delivery components include cartridges (e.g., dab or wax cartridges, oil cartridges, etc.), pods (e.g., dab or wax pods, oil pods, dry herb pods, etc.), and the like. The substance stored in the substance delivery component can also vary and may include oils, concentrates, waxes, and other plant-based solids. In some instances, the term “cartridge” is used for the sake of brevity but should be understood as including all types of substance delivery components. In some cases, the substance delivery component also includes a mouthpiece to facilitate inhalation, for example, as is commonly found in many cartridges and pods.
The terms “electronic device” and “electronic inhalation device” is used herein to denote the power source component of any type of personal inhalant dispensing device that is configured to electrically connect to a substance delivery component in order to power the heating element therein. The electronic device may include a rechargeable or disposable battery, or a port or connector for coupling to a power supply (e.g., via a USB connection). In addition, the electronic device may include a receptacle for receiving the substance delivery component therein, or an external connector for connecting to the substance delivery component. Some electronic devices also include one or more user input devices for controlling operation of the cartridge and/or electronic device. Exemplary electronic inhalation devices include the battery components of vape pens, electronic dabbing devices, and other personal vaporizers.
The term “substance” is used herein to denote any type of product capable of being vaporized and inhaled by a user and is not limited to a particular consistency, format, blend, strain, ingredient-type, or otherwise. For example, the substances may include various types of cannabis, tobacco, and other plant-based products, including blends and/or strains thereof, and may come in various forms, including, for example, a wax or other concentrate, a concentrated oil or other solution, or other solid substance. The substances may also include vaporizable medicinal products.
FIG. 3 illustrates an exemplary dab cartridge 100 (also referred to herein as an “inhalant delivery device”) comprising a handle portion 102, a central portion 104 (also referred to herein as a “main body”), and a base portion 106, in accordance with embodiments. The handle portion 102 and the base portion 106 are removably or detachably coupled to opposite ends of the central portion 104, such that the base portion 106 may be detached from the central portion 104 without removing the handle portion 102, and vice versa. The handle portion 102 and the central portion 104 may be collectively referred to as an upper housing of the dab cartridge 100, while the base portion 106 may be referred to as a lower housing of the dab cartridge 100. Various types of connectors, fasteners, or connection mechanisms may be used to couple the three portions 102, 104, and 106 to each other, including, for example, magnetic connectors, threaded connectors, friction or interference fit fasteners, snap fit fasteners, or any other suitable detachable or non-permanent connection mechanism. In a preferred embodiment, a bottom end (also referred to herein as a “second end”) of the central portion 104 is coupled to a top end of the base portion 106 using a threaded connection, for example, as shown in FIG. 3. In embodiments, the handle portion 102 can be coupled to a top end (also referred to herein as a “first end”) of the central portion 104 using a magnetic connection, snap fit or friction fit mechanism, or other suitable connection.
The handle portion 102 comprises a mouthpiece 108 with an opening 110 for allowing vapors to exit the dab cartridge 100. During use, the user places the mouthpiece 108 in their mouth and applies suction pressure to intake vapors produced by the cartridge 100. The mouthpiece 108 also includes an internal passageway 112 that is in communication with the central portion 104. The central portion 104 operates as a chimney for carrying or guiding vapors generated by the base portion 106 to the mouthpiece passageway 112. The handle portion 102 may include a plurality of apertures or vent holes for allowing vapors to flow from the chimney or central portion 104 into the passageway 112 (e.g., as shown in FIG. 11G).
The handle portion 102 also comprises an integrated dosing tool 114 (also referred to herein as a “measuring tool”) that is coupled to a distal end of the mouthpiece 108, or opposite the opening 110, and extends into the central portion 104 once the handle portion 102 is coupled to the central portion 104, as shown in FIG. 3. The dosing tool 114 includes a plunger 116 that is capable of grabbing one dose of dab concentrate from a concentrate jar or other storage location, and depositing the dab on the base portion 106 in a relatively mess-free manner. More details about the dosing tool 114 will be described with respect to FIGS. 11A-G.
Referring additionally to FIGS. 4-7, the base portion 106 comprises a concentrate dish 118 (also referred to herein as a “heating component”) for receiving a dab concentrate 120 on a top surface 122 (also referred to herein as a “heating surface”) of the dish 118. As shown in FIG. 7, the concentrate dish 118 is coupled to a heating chamber 124 of the base portion 106. In some embodiments, the concentrate dish 118 may be removably secured to the heating chamber 124 using a magnetic connector or other appropriate connection mechanism. In such cases, the concentrate dish 118 may be removed for cleaning purposes, or to be replaced with a new dish. In other embodiments, the concentrate dish 118 may be permanently or fixedly attached to the heating chamber 124.
As shown, the concentrate dish 118 has a substantially circular top surface 122 that curves or slopes inwards (i.e. has a generally concave shape) and is generally smooth or without sharp edges. Due to the shape and even texture of the top surface 122, dab concentrate naturally slides to, or collects in, a center of the top surface 122, either in its waxy or solid form, or after the solid form has been melted to a liquid, or both. As shown in FIG. 6, the top surface 122 ends at an outer rim or lip 126 that forms an outer circumference of the concentrate dish 118 and is configured to extend out past a lower sidewall 128 of the concentrate dish 118. That is, an inner circumference formed by the lower sidewall 128 is less than the outer circumference formed by the outer rim 126. The outer rim 126 may be configured to sit flush with and/or rest on top of a threaded wall 130 of the heating chamber 124, to prevent the dab concentrate from spilling onto the threaded wall 130 or other external surfaces of the heating chamber 124. When the concentrate dish 118 is coupled to the heating chamber 124, the lower sidewall 128 extends down into a basin 132 of the heating chamber 124, while the outer rim 126 rests on top of the threaded wall 130, as shown in FIG. 5. In embodiments, the top surface 122, the outer rim 126, and the lower sidewall 128 can be made of ceramic, stainless steel, or other easily cleanable or wipe-able surface that is also suitable for heating.
The threaded wall 130 on the exterior of the heating chamber 124 may be configured for coupling to a threaded internal wall 134 of the central portion 104, as shown in FIG. 3. In some embodiments, when the central portion 104 is attached to the base portion 106, the concentrate dish 118 remains securely in place between the two portions without requiring a separate fastening mechanism.
As shown, the heating chamber 124 further includes a coupler 136 at a lower end of the chamber 124, opposite the threaded wall 130. The coupler 136 can be configured to secure the cartridge 100 to a receptacle of the electronic inhalation device (e.g., receptacle 16 shown in FIG. 1C). In embodiments, the coupler 136 may be annular and/or have a hollow center to enable electrical connection between an interior of the heating chamber 124 and the battery of the electronic inhalation device. In the illustrated embodiment, the coupler 136 includes a threaded coupler (e.g., having a 510 thread) configured to allow the cartridge 100 to be screwed into a vape pen or the like. In some embodiments, the coupler 136 may also include a magnetic connector (not shown) that is coupled over the threaded coupler and is configured for magnetically coupling the cartridge 100 to the electronic inhalation device. In other embodiments, the coupler 136 may only include the magnetic coupler for securing the cartridge 100 to the electronic inhalation device.
Referring additionally to FIGS. 8-10, the concentrate dish 118 further includes an integrated heating element 138 for heating dab concentrate placed on the top surface 122. The heating element 138 is shaped as a coil and is configured to spiral around, or otherwise follow the contours of, the top surface 122, so that a majority portion of the top surface 122 is in contact with, or is directly heated by, the heating element 138. For example, as shown in FIG. 8, the heating element 138 can have a generally concave structure to substantially match or conform to the generally concave shape of the concentrate dish 118. In embodiments, the concentrate dish 118 is formed or molded around the heating coil in order to fully integrate the heating element 138 within the dish 118 and to maximize contact between the heating element 138 and the top surface 122. As an example, hot ceramic may be poured into a mold containing the heating coil 138 and then cooled, thus forming a unitary or one-piece structure comprised of the top surface 122, outer rim 126, and sidewall 128 of the concentrate dish 118, and the heating element 138 fully embedded therein.
The concentrate dish 118 further include one or more conductive portions for delivering power to the heating element 138 from a power source, or the battery of an electronic inhalation device. As shown in FIG. 10, the concentrate dish 118 may include a first conductor 140 attached (e.g., soldered) to a first leg 138 a of the heating element 138 and a second conductor 142 attached (e.g., soldered) to a second leg 138 b of the heating element 138. In embodiments, the first conductor 140 can be configured to provide a positive electrical connection between the heating element 138 and the battery, and the second conductor 142 can be configured to provide a ground connection between the same.
For example, as shown in FIG. 10, the second conductor 142 is configured to form an annular ring around the first conductor 140, which is positioned concentrically within the second conductor 142. As shown in FIG. 4, when the concentrate dish 118 is coupled to the heating chamber 124, the second conductor 142 directly contacts an internal wall of the heating chamber 124 in order to provide the ground connection, and the first conductor 140 directly contacts a conductive pin 144 of the heating chamber 124. As also shown, the heating chamber 124 may include a cavity 146 below the basin 132 for receiving the first conductor 140 therein. The cavity 146 may be configured so that the first conductor 140 does not touch the internal walls of the heating chamber 124, thus keeping ground conductor 142 physically and electrically separated from the positive conductor 140. In embodiments, the conductive pin 144 extends out from, or is accessible from an exterior of, the heating chamber 124, so as to be placed in electrical contact with a power source once the cartridge 100 is coupled to an electronic inhalation device, for example. In this manner, the conductive pin 144 can deliver power to, or otherwise activate, the heating element 138. In embodiments, the heating chamber 124 may be made of metal or any other material suitable for securely and electrically coupling the cartridge 100 to an electronic inhalation device.
FIGS. 11A-G illustrate an exemplary method 200 of using the dab cartridge 100 shown in FIGS. 3-10, in accordance with embodiments. FIG. 11A illustrates a first step 202, wherein the handle portion 102 is removed from the cartridge 100 and the integrated dosing tool 114 is inserted into a concentrate jar for storing dab concentrate 120. FIG. 11B illustrates a second step 204, wherein the dosing tool 114 is used to lift a single dose of dab concentrate 120 out of the jar.
As shown in FIG. 11A, the tool 114 comprises the plunger 116 (also referred to herein as a “capturing mechanism”), which extends from a housing portion 115 of the tool 114. According to embodiments, the plunger 116 is configured to grasp and hold a controlled or preset amount of concentrate, such as a single dose. For example, the plunger 116 may include a tubular sidewall 148 that extends down from a bottom wall of the tool housing and has a downward-facing open end. The plunger 116 also includes a solid tube 150 that is at least partially disposed within the sidewall 148 and at least partially disposed within the tool housing. The tube 150 may be configured to move up and down, or travel, within the tubular sidewall 148. When the tube 150 is in a neutral position, e.g., as shown in FIG. 11A, the tube 150 does not reach the open end of the sidewall 148, leaving a clearance 152 between the open end of the sidewall 148 and a bottom surface of the tube 150. The clearance 152 determines a depth of the cut made into the concentrate and therefore, the amount of substance that is retrieved. In embodiments, the clearance 152 can be configured (e.g., sized and/or shaped) to have a volume that corresponds to a controlled amount of concentrate, such as the equivalent of one dose. In some cases, the sidewall 148 may be thin and at least somewhat sharp, so that the plunger 116 can easily cut into the dab concentrate 120, e.g., similar to a cookie cutter or die cut. In some embodiments, a height of the clearance 152 is adjustable to enable the plunger 116 to capture different sized doses for different types of concentrates. For example, the tube 150 may have an adjustable length and/or may be movable relative to the sidewall 148, so that the clearance 152 can be increased or decreased, as needed. In one example embodiment, the clearance 152 has a height of about 0.667 mm.
FIG. 11C illustrates a third step 206, wherein handle portion 102 is placed over or on top of the base portion 104, and the concentrate dose 120 is released from the tool 114 towards the concentrate dish 118 using a dispensing mechanism of the tool 114. FIG. 11D illustrates a fourth step 208, wherein the concentrate 120 is disposed on, or has fallen onto, the concentrate dish 118 and automatically or naturally slides to the middle of the dish 118. In embodiments, the dispensing mechanism of the dosing tool 114 includes a spring mechanism 154 configured to help release the concentrate 120 from the plunger 116. As shown in FIG. 11B, the spring mechanism 154 may be positioned at a base 156 of the mouthpiece 108 and may be coupled to or around the tube 150. In a neutral position, for example, as shown in FIG. 11B, the spring mechanism 154 (or spring) presses against the base 156 in order to bias the mouthpiece 108 upwards. In order to release the concentrate 120, the user presses down on top of the mouthpiece 108, which cases the mouthpiece base 156 to press down on, or compress, the spring mechanism 154, which in turn causes a longitudinal movement of the tube 150 down through the sidewall 148. As shown in FIG. 11C, the tube 150 may be configured (e.g., sized) to stop at the open end of the sidewall 148, and the downward force exerted by the tube 150 causes the concentrate 120 to break free from the tool 114 and drop down onto the concentrate dish 118. Removing the downward pressure on the mouthpiece 108 causes the spring mechanism 154 to return or spring back to its neutral position, as shown in FIG. 11E. Thus, the dispensing mechanism of the dosing tool 114 may include not only the spring mechanism 154, but also the mouthpiece 108 that is used to actuate the spring. In some embodiments, the tool 114 may be made of silicon, ceramic, stainless steel, or other material that is suitable for heated environments and can be easily cleaned.
FIG. 11F illustrates a fifth step 210, wherein the handle portion 102 is secured to the central portion 104, and the central portion 104 is secured to the base portion 106. Though FIG. 11F, shows the handle portion 102 being secured to the central portion 104 first, it should be appreciated that the central portion 104 could also be secured to the base portion 106 first, as shown in FIG. 11E. Once the cartridge 100 is fully re-assembled, the user may begin dabbing (or vaping) by electrically coupling the dab cartridge 100 to an electronic inhalation device (not shown) and activating the battery of such electronic device (e.g., by pressing an activation button). In response, power may be delivered to the heating element 138 via the conductive pipe 144, which may be electrically coupled to the electronic inhalation device once the cartridge 100 is installed therein. This initiates a preheat function of the cartridge 100, which causes the heating element 138 to quickly heat up. Once the heating element 138 reaches a desired temperature, the battery may hold that temperature for a fixed period of time (e.g., 2-4 seconds) and then automatically shut off. In the meantime, the heat from the heating element 138 causes the dab concentrate 120 to vaporize. FIG. 11G illustrates a step 212, wherein, in response to user inhalation at the mouthpiece 108, the resulting vapors 158 can travel through the length of the central portion 104 and the length of the mouthpiece 108, and then out the opening 110. As will be appreciated, the cartridge 100 can be reused by repeating the steps of method 200.
While the illustrated embodiment includes a plunger-type mechanism 116 to pick up dab concentrate, the dosing tool 114 may take on other forms, including, for example, a small silicon spatula or scoop, a metal screwdriver head, hook, or scoop, etc. In some embodiments, the plunger 116 may be replaceable and/or interchangeable with other types of tools or tips, such as, for example, a cleaning tool (e.g., a brush or swab), different sized tools (e.g., a plunger with a different diameter and/or height) configured for use with different types of concentrate, a new tool to replace a used one, etc. In such cases, the plunger 116 may be removably secured to the housing portion 115 at a bottom end of the tool 114, for example, using a threaded connection as shown in FIGS. 11A-C, and the new tools (not shown) may include a compatible threading for attachment to the tool end.
In some embodiments, the cartridge 100 may come with two concentrate dishes that may be used interchangeably, for example, for different types of concentrate. While the cartridge 100 is shown herein as having a generally cylindrical shape, other embodiments may employ other shapes, including, for example, a flattened shape, a rectangular shape, or any other shape that is compatible with a given electronic inhalation device.
Some embodiments include an intelligent inhalant dispensing system comprising a “smart” cartridge or other substance delivery component configured to provide information about the contents of the cartridge (e.g., exact type of strain, chemical makeup, or other substance identifying information), and a “smart” electronic inhalation device configured to obtain information from a smart cartridge installed therein and facilitate monitoring, measuring, controlling, and/or tracking usage of the cartridge or device. In each cases, the cartridge 100 may be configured as a smart cartridge that contains information identifying the substance contained in the cartridge, dosing information for that substance, and in some cases, heating profile information specific to the substance. The smart inhalation device may contain information specific to the user of the device, and may combine this information with the information from the cartridge to make dosing and administration decisions. For example, the smart inhalation device may include a dosage administration system configured to electronically monitor dosing and prevent excessive dosing, and a cartridge identification system configured to identify the cartridge being used and obtain and/or provide dosage information associated therewith. The inhalation device may work in association with the smart cartridge to control dosing of the substance contained in the cartridge, monitor the user's inhalant consumption over time, provide the user with various information about the substance, such as, e.g., flavor profile, common side effects, heating profile, etc., and, in some cases, provide recommendations for new products or substances that the user may enjoy based on the user's consumption history. In some embodiments, the inhalation device also includes a preparation system configured to monitor preparation of the substance to be vaporized (e.g., through shaking, heating temperature and/or time, etc.) and provide an indication when the substance is ready for use. One or more of the above features may require the use of wireless communication with a personal electronic device, such as, e.g., a smartphone.
