[0005] Citing Join
[0006] All publications and patent applications mentioned in this specification are incorporated herein by reference in their entirety, just as each individual publication or patent application is specifically and individually indicated to be incorporated herein by reference. Technical Field
[0007] The apparatus, system, and method described herein can be used to determine the dosage of the vapor and / or the amount of active ingredient in the vapor for a user inhaling the vapor. Background Art
[0008] Vaporizers, including electronic vaporizer devices (or e-vaporizer devices), allow the delivery of vapors containing one or more active ingredients via inhalation. Electronic vaporizer devices are increasingly popular for prescribed medical uses of drug delivery and for consuming tobacco and other plant-based flammable inhalable materials. In particular, electronic vaporizer devices can be portable, self-contained, and easy to use. Unfortunately, even for medical applications, these devices may vary in the amount of vapor and / or active ingredient delivered.
[0009] To date, attempts to determine the dosage of the active ingredient in vapor and / or vapor have not been satisfactory. Systems that predetermine the dosage by limiting the amount of material to be delivered during a session often incorrectly assume that all material will be inhaled and may be unadjustable for some doses. Such systems also require measuring the amount of material and accurately measuring the mass and / or volume of the material delivered for evaporation, or measuring the difference between the initial mass / volume and the mass or volume after delivery. These measurements can be difficult, require a high level of accuracy and are expensive, and may lead to inaccurate results.
[0010] What is needed are methods and devices (e.g., systems and / or apparatuses) for delivering steam and accurate delivery doses, for example, within a reasonable range of precision / error. In particular, it would be helpful to provide methods and devices for determining the delivery dose of steam and / or components in the steam by monitoring the electrical activity of the device and, in some cases, monitoring the temperature of the device (which can be estimated electrically or measured directly). Furthermore, it would be helpful to provide such methods and devices for delivering a predetermined dose and / or alerting the user or caregiver when a threshold dose is reached or exceeded. Additionally, providing electronic records of the delivered dose may also be helpful. Summary of the Invention
[0011] This document discloses methods and apparatuses comprising devices and systems capable of estimating, measuring, and / or predicting the amount of steam and / or materials (including active ingredients) in the steam that can be delivered to a user. In particular, this document describes electronic evaporators and methods of using them, which determine the dosage / amount of steam and / or materials in the steam primarily or entirely based on electrical properties, such as the power or energy applied to an evaporation element (e.g., a coil), and in some variations, the temperature at which the material is evaporated. In some variations, the temperature at which the material is evaporated can be estimated / approximated based on the electrical properties of the evaporation element, such as the temperature coefficient of resistance or TCR.
[0012] Typically, the methods and apparatus described herein can accurately determine the delivered dose to within approximately 20% of the actual delivered dose (e.g., within approximately 19%, within approximately 18%, within approximately 17%, within approximately 16%, within approximately 15%, within approximately 14%, within approximately 13%, within approximately 12%, within approximately 11%, within approximately 10%, etc.).
[0013] This document also describes methods and apparatus for calibration. Calibration can be performed automatically or manually, and can be carried out at the factory. In some variations, calibration can be performed by the user. Calibration may include input of values, including constant values. Calibration can be performed when the evaporated material (including the carrier and / or active ingredient) is altered.
[0014] While many of the examples described herein relate to determining the dosage of nicotine or other tobacco-related materials, it should be understood that these methods and devices can be used for the delivery and dosing of any volatile material, including therapeutic medicines. Examples of active ingredients that can be used as described herein are provided below, and these may include herbal medicines, nutritional supplements, pharmaceuticals, and combinations thereof. The methods and devices described herein can deliver relatively pure materials directly to the lungs, which can accelerate action in the body, including onset and off-time.
[0015] In some embodiments, this document discloses methods and apparatuses that allow users to control the amount of steam generated from evaporable materials. This allows for a customized evaporation experience for various evaporable materials, as well as an overall improved user experience. The methods disclosed herein can be implemented using any electronic evaporator device or evaporation apparatus configured as described herein.
[0016] For example, this disclosure provides a method for dose control and calibration of an electronic evaporator device, which includes measuring the amount of material evaporated from the evaporable material of the electronic evaporator device or evaporation apparatus relative to power, time, and temperature. These methods and apparatuses may include an evaporative dose (e.g., mass) prediction system, which includes establishing a relationship between total particulate matter (TPM) or active ingredient evaporation or release as a function of temperature (which can be determined by resistivity or by a temperature-proportional characteristic), time (which can be correlated with the detection of a user's inhalation / vaporization), and the power consumption of the evaporation element. In some embodiments, this disclosure provides a method for metrological dose control and calibration of an electronic evaporator device, which includes measuring the amount of material evaporated from the evaporable material of the electronic evaporator device or evaporation apparatus relative to power and temperature; in particular, it provides a method including an evaporative dose prediction system, which includes establishing a relationship between total particulate matter (TPM) or active ingredient evaporation or release as a function of temperature and power consumption.
[0017] Therefore, this document describes a method for determining the dose of evaporable material delivered to a user of an evaporation device within a time period. The time period typically comprises multiple sequential time intervals. In any of these methods and apparatuses, the evaporation device may include a heater controller, a heater, a source of the evaporable material, and an evaporation dose predictor unit. For example, the method may include: calculating a partial dose for each of the sequential time intervals, wherein the partial dose is calculated from the power delivered by the heater controller to the heater for evaporating the evaporable material during the partial dose time interval, the temperature of the evaporable material evaporated during the partial dose time interval, and the temperature of the evaporable material evaporated before the partial dose time interval; and summing the calculated partial doses in the evaporation dose predictor unit to determine the total dose of vapor delivered during the time period.
[0018] Any calculation or summation steps can be performed within the device (e.g., locally, such as within a controller, which may include an evaporative dose predictor unit or a portion thereof, housed in the same enclosure as other parts of the device, such as a heater controller), and / or they can be performed remotely, for example, within a processor that wirelessly receives information such as power, temperature, and / or partial dose. The evaporative dose predictor unit (which may herein be referred to as an evaporative dose predictor, evaporative dose predictor circuitry, or evaporative dose predictor control logic) can be located remotely from other parts of the device, including in a remote server (e.g., a cloud server, smartphone, or wearable device), and can wirelessly receive information.
[0019] Typically, any of these methods may also include determining the amount of active ingredient delivered to the user based on the total dose of the delivered vapor. This can be done, for example, using the concentration of the active material within the source of the volatile material (e.g., giving the amount of active ingredient per unit mass or unit volume of the evaporable material within the source of the evaporable material).
[0020] Any of these methods may further include determining the temperature change (ΔT) of the evaporable material being evaporated over each of the sequential time intervals relative to the temperature of the evaporable material being evaporated.
[0021] Any suitable time interval (dose interval) can be used, which may be sequential (e.g., sequential time interval), and the time interval may be based on or reflect the sampling rate of the device used to determine the dose. For example, the time interval may be from approximately 200 msec to approximately 10 msec.
[0022] Dosage calculation may also include calculating a partial dose for each of the sequential time intervals, which is also based on the latent heat and specific heat of the material. For example, as described in more detail herein, the constant may be empirical or theoretical (e.g., derived from the latent heat and / or specific heat of the evaporated material) and may be initially provided to the apparatus described herein, or may be periodically updated (e.g., in a calibration step) of any of these apparatuses.
[0023] Typically, by balancing the energy supplied to the material by the heater (e.g., a Joule heating coil), the calculation of the partial dose (mass of vapor) delivered by the device can be based on the mass / energy balance in the evaporated material, including the energy change caused by evaporation, the heat change as heat is absorbed by the material to be evaporated, and the energy lost from the system via heat transfer. As described herein, this can be expressed with unexpected precision for the energy (power) applied to the heater and the temperature immediately before, during, and after the evaporation of the evaporable material. Variations in the evaporator's structure (heater shape, material, size, etc.) and the evaporated material can be considered constants and ignored (e.g., provided with unitless or self-referenced values). For example, the step of calculating the partial dose for each of the sequential time intervals may include subtracting from a first constant multiplied by the power supplied to the heater by the heater controller for evaporating the evaporable material during the partial dose time interval, a second constant multiplied by the temperature of the evaporable material evaporated during the partial dose time interval, and a third constant multiplied by the temperature of the evaporable material evaporated before the partial dose time interval. Alternatively, the step of calculating a partial dose for each of the sequential time intervals may include: subtracting from a first constant multiplied by the power delivered by the heater controller to the heater for evaporating the evaporable material during the partial dose time interval by a different second constant multiplied by the difference between the temperature of the evaporable material evaporated during the partial dose time interval and the temperature of the evaporable material evaporated before the partial dose time interval, and a different third constant multiplied by the temperature of the evaporable material evaporated before the partial dose time interval.
[0024] Typically, partial dose calculations can be performed using the temperature of the evaporable material evaporated during the partial dose interval and the temperature of the evaporable material evaporated before the partial dose interval, including using electrical properties proportional to the temperature of the heater as the temperature of the evaporable material evaporated during the partial dose interval. Therefore, the temperature mentioned in any calculation step described herein (e.g., the temperature of the evaporable material evaporated during the partial dose interval and the temperature of the evaporable material evaporated before the partial dose interval) can refer to any value proportional to the actual temperature (e.g., using the temperature coefficient of resistance to determine a temperature-proportional value without conversion (using a constant determined from the system to ℃ or °F)).
[0025] Typically, the methods and apparatus described herein can realize the obtained dose information (or partial, running, or summed dose information), for example, to report and / or control the operation of the device or to send it to auxiliary (e.g., remote) devices. For example, any of these methods may further include alerting the user when the total dose of steam delivered during the time period reaches or exceeds a preset threshold. Any of these methods may further include deactivating the device when the total dose of steam delivered during the time period reaches or exceeds a preset threshold. Any of these methods (or apparatuses configured to implement them) may further include calculating and displaying the cumulative total dose of steam delivered during a session period including the time period. Thus, the total operating dose during multiple aspirations (each aspiration can be considered a time period, or the time period can be the entire session in which the device is turned on for evaporating the material, or a multiple of the time period until reset by the user).
[0026] Typically, any of these methods may include detecting a user's inhalation on the evaporator device, wherein the time period corresponds to the duration of the detected user's inhalation.
[0027] Any suitable evaporable material can be used. Typically, the evaporable material can be a liquid. The evaporable material can contain any active ingredient.

The evaporable material may also contain nicotinic acid salts, glycerol, and propylene glycol.
[0028] As described above, the evaporative dose predictor unit can be part of a controller. In some variations, the evaporative dose predictor and the heater controller are both part of the same controller. In some variations, the evaporative dose predictor and the heater controller are separate.

The measurement step can be performed at any suitable frequency, for example, at a frequency of 5 Hz to 50 Hz within the first time period. The measurement step can also be performed at a frequency of 10 Hz to 30 Hz within the first time period.
[0034] As described above, the amount of steam delivered to the user during the first time period can be further determined based on the latent heat and specific heat of the material.

[0038] Any of these methods may further include warning the user when the determined amount of steam delivered to the user reaches or exceeds a preset steam threshold, and / or deactivating the device when the determined amount of steam reaches or exceeds the preset steam threshold.
[0039] Any of these methods may also include detecting the user's suction on the evaporator device, wherein the measurement step is performed only during the detected suction.
[0040] As described above, any suitable material to be evaporated (evaporable material) can be used in any of the methods described herein. Typically, the evaporable material can be a liquid. The evaporable material can contain any active ingredient. For example, the evaporable material can contain tobacco-based materials. The evaporable material can contain botanicals.

[0085] Typically, this document describes a method for quantifying, and in some variations for controlling, the amount of vapor delivered to a user from an evaporable material in an electronic evaporator device. In some variations, the electronic evaporator device includes (optionally): a suction sensor, a power supply, a heating element controller, a heating element, a temperature sensor, an evaporation dose predictor unit, an alarm unit, and / or control logic. Methods for quantification and / or control may include: (optionally) a suction sensor for detecting a user's suction; a heating element controller that measures the amount of power delivered from a power source during the user's suction; a temperature sensor that measures the temperature or temperature distribution generated by the heating element during the user's suction; an evaporation dose predictor unit that calculates the amount of steam delivered from the evaporable material to the user based on the amount of power and temperature during the user's suction, or based on the amount of power and temperature distribution during the user's suction; and a) activating the alarm unit to warn the user when the amount of steam delivered reaches or exceeds a preset steam quantity threshold for the user's suction, or when the cumulative amount of steam delivered from multiple suctions reaches or exceeds the preset steam quantity threshold, or b) implementing control logic to deactivate or modify the output of one or more features of the electronic evaporator device when the amount of steam delivered reaches or exceeds the preset steam quantity threshold for the user's suction, or when the cumulative amount of steam delivered from multiple suctions reaches or exceeds the preset steam quantity threshold, or c) both a) and b).
[0086] As will become apparent as described in more detail below, a suction sensor is not necessary; when the user does not suction, the device and method described herein will simply return a zero value for the delivered dose, since the evaporator will not form vapor without suction. Furthermore, the described method can be considered generally discontinuous, as the estimation of the vapor dose is performed at discontinuous intervals forming partial doses, which can later be summed to form the total delivered dose. This configuration can partially allow these methods and devices to operate with unexpected accuracy, even with highly variable suction duration and distribution.
[0087] This document also provides an electronic evaporator configured to quantify and / or control the amount of vapor delivered to a user from an evaporable material in the electronic evaporator device, wherein the electronic evaporator device may include any of the following: (optionally) a suction sensor for detecting the user's suction; a heater controller (also known as a heating element controller) configured to determine the amount of power delivered from a power source during the user's suction; a temperature sensor (which may be a direct sensor such as a thermistor, or a temperature sensing unit that determines, for example, the temperature of the heater based on the electrical properties of the heater) configured to determine the temperature or temperature distribution generated by the heating element during the user's suction; and an evaporation dose predictor (also known as an evaporation dose predictor unit or circuit) based on the power applied to the heater and the temperature of the heater during the user's suction. The amount of steam delivered from the evaporable material to the user is calculated based on the amount of power and temperature distribution during the user's suction, or on a temperature (which may be an estimate of the temperature of the evaporable material during evaporation) or on a power level and temperature distribution during the user's suction. This includes one or more of the following: a) an alarm unit configured to warn the user when the amount of delivered steam reaches or exceeds a preset steam quantity threshold for the user's suction, or when the cumulative amount of steam delivered from multiple suctions reaches or exceeds the preset steam quantity threshold; b) a deactivation unit configured to automatically deactivate one or more features of the electronic evaporator device when the amount of delivered steam reaches or exceeds the preset steam quantity threshold for the user's suction, or when the cumulative amount of steam delivered from multiple suctions reaches or exceeds the preset steam quantity threshold; or c) both a) and b).
[0088] Figure 1A This is a schematic diagram of an example of an electronic evaporator device 100' including an evaporation dose predictor unit 109. Typically, any evaporator device described herein may include a heater controller 105, a heater 106, a source 103 of evaporable material, a power source (e.g., a battery, not shown), and an evaporation dose predictor unit 109. The evaporation dose predictor unit 109 may include a clock 119 and / or a memory (memory unit) 117, or these elements may be part of an overall circuitry including a processor 110 communicating with the evaporation dose predictor unit.
[0089] The heater can be any suitable heater, including resistance heaters, such as resistance coils. The heater is typically coupled to a heater controller, such that the heater controller applies power (e.g., from a power source) to the heater. The heater controller may include regulating control logic that adjusts the temperature of the heater by regulating the applied power. The heater controller may include a dedicated or general-purpose processor, circuitry, etc., and is typically connected to and can accept input from the power source to regulate the power applied to the heater. A controller forming or including a heater controller may also include additional controller / processor and execution logic 110, such as an evaporation dose predictor unit, alarm / alarm logic, and / or temperature detector / sensor 107, or these components may be separate.
[0090] Any source of evaporable material can be used, including containers (e.g., orifices, chambers, cylinders, etc.) containing the material to be evaporated. The material to be evaporated may include a carrier and one or more active ingredients, as discussed in more detail herein.
[0091] Typically, an evaporative dose predictor unit is configured to divide a time period (e.g., during a single suction) into multiple consecutive time intervals, which may be referred to as partial dose intervals, and to determine a partial dose (or mass) of vapor generated during each partial dose interval. The evaporative dose predictor unit can then sum these to determine the actual dose generated and, consequently, the dose delivered to the user. Therefore, the apparatus including the evaporative dose predictor unit may include a timer or clock 117 and may generate intervals of any suitable duration within the time period (e.g., 10 msec to 200 msec). Thus, the evaporative dose predictor unit is capable of sampling at frequencies associated with the duration of the time interval (e.g., 5 Hz to 100 Hz, 5 Hz to 120 Hz, 5 Hz to 140 Hz, 5 Hz to 150 Hz, 5 Hz to 180 Hz, 5 Hz to 200 Hz, 5 Hz to 300 Hz, etc.). The evaporative dose predictor unit typically bases the calculation of each partial dose on inputs from a heater controller, which may include power applied before or at the start of each partial dose interval. The evaporation dose predictor unit also receives inputs proportional to the temperature at the beginning and end of each partial dose interval (e.g., temperature or a value proportional to the temperature at the end of the immediately preceding partial dose interval). In a variant where the temperature is the average of each dose interval, the evaporation dose predictor unit may receive the temperature (or a proportional value) of the dose interval as well as the temperature (or a proportional value) of the dose interval immediately preceding it. The evaporation dose predictor unit can then use this applied power and temperature information to calculate the dose (e.g., mass) of the steam during that interval, as will be described in more detail below. The values of these intervals (the values of the dose intervals) can be summed over the entire time period to determine the total dose of the steam produced; the evaporation dose predictor unit can also convert this steam dose into the dose of the active ingredient in the steam, for example, based on the concentration of the active ingredient in the evaporable material. U.S. Patent Application No. 14 / 581,666, filed December 23, 2014, entitled “Vaporization Device Systems and Methods” (the entire contents of which are incorporated herein by reference), also describes an evaporator including methods and apparatus for temperature measurement and control similar to those described above.
[0092] As described above, in some variations, the temperature of the evaporable material evaporated by the device is determined by the heater without the need for additional sensors. For example, the temperature of the heater can be approximated using the relative change in the heater's resistance (e.g., the temperature coefficient of resistivity) and a reference resistor. While a conversion factor can be used to convert the ratio of the heater's resistivity to the reference resistivity into an actual temperature value, in some variations, the system, particularly the evaporation dose predictor unit, can directly use the proportional values without multiplying by the conversion factor. Therefore, these values are "proportional" to the temperature. For example, any of these devices could include logic for determining the heater's temperature based on the TCR. The resistance (Rt) of the heater (e.g., a resistance heater) can be measured during device operation. 加热器 ) and the resistance (R) of the reference resistor separate from the heater. 参考 The ratio of heater resistance to reference resistance (R) 加热器 / R 参考 The temperature is linearly proportional to the heater temperature (above room temperature) and can be directly converted to a corrected temperature. For example, a value such as (R) can be used. 加热器 / R 参考 The expression -1)*(1 / TCR) is used to calculate the change in heater temperature relative to room temperature, where TCR is the temperature coefficient of the heater's resistivity. In one example, the TCR for the heater used in a particular device is 0.00014. When determining partial doses and dosages as described herein, the temperature values used (e.g., the temperature of the evaporable material during the dosing interval, T...) i (described in more detail below) can refer to a unitless resistance ratio (e.g., R0). 加热器 / R 参考 ), or it can refer to a standardized / corrected temperature (e.g., in °C).
[0093] Therefore, the evaporative dose predictor unit can be configured to determine the dose of steam delivered to the user within a time period based on: the amount of power delivered by the heater controller to the heater for evaporating the evaporable material during each of a plurality of partial dose intervals within the time period, the temperature of the evaporable material evaporated during each partial dose interval, and the temperature of the evaporable material evaporated before each partial dose interval. As mentioned above, the temperature of the evaporated evaporable material can refer to a temperature-proportional input.
[0094] Figure 1AOther optional features shown may include a suction sensor 113 and / or a dose output device 115. The suction sensor typically detects the application of suction by the user and may include a pressure sensor, a flow sensor, or a contact sensor (e.g., a lip contact sensor). The dose output device may include any suitable output device, including visual output devices (e.g., LEDs, monitors, etc.), audio output devices (buzzers, tones, etc.), tactile output devices (vibrators, etc.), etc. For example, the dose output device may function as an alarm or alert to the user when a dose threshold is reached.
[0095] Figure 1B-1D This illustrates an exemplary compact electronic vaporizer device assembly 100 for generating an inhalable aerosol, such as an electronic cigarette, medical inhaler, or other inhalation device. The compact electronic device 100 may include a device body 200 having a cartridge container 210 for receiving a cartridge 300, or a "chamber" removably inserted into the device body 200. A mouthpiece 310 allows a user to inhale material atomized by the device.
[0096] The device body 200 may include a power source 230 such as a rechargeable battery, a printed circuit board 240 containing a microcontroller with operating logic and software instructions for the device, and a suction sensor 270 for detecting when a user draws steam from the device.
[0097] Box 300 may include a heater 360 and a material storage chamber 320 configured to store material to be evaporated. The heater 360 may be powered by a power supply 230. In this example, as described above and herein, the heater 360 may function as a temperature sensor, for example, using a temperature coefficient of resistance (TCR) and a reference resistor. Alternatively or additionally, a separate temperature sensor (e.g., a thermistor, etc.) in thermal contact with the heater and / or the evaporable material may be used. Typically, the temperature sensor may be configured to measure the temperature of the evaporable material within the heater 360. The temperature of the heater may be controlled by a microcontroller on PCB 240.
[0098] Device 100 (or any other evaporation device) may include an on-board processor configured to determine the amount of material to be evaporated and delivered to the user.
[0099] Figure 1E The flowchart shown represents another exemplary evaporator device capable of determining the amount of material evaporated within the device (apparatus 100). As shown, power supply 230, heater 360, temperature sensor 250, and suction sensor 270 are communicatively connected to control unit 10 (which may be...) Figure 1B-1D(a portion of one or more printed circuit boards 240 shown).
[0100] The control unit 10 may include a heating element controller 4, an evaporation mass predictor (VMP or VMP unit, which may be of the type of evaporation dose estimation / prediction unit) 8, and a memory 11. In some embodiments, a user interface 13 on the device may provide the user with device-related information, such as the amount of inhaled vapor. An interface controller 12 within the controller may be configured to control the user interface 13. In one embodiment, the device further includes an alarm unit.
[0101] To determine the amount of steam received by the user, control unit 10 can forward temperature reading 7 and power reading 5 during suction (which can be determined by suction sensor 15) to VMP unit 8, which can calculate the predicted evaporation mass. In some embodiments, VMP unit 8 forwards the predicted evaporation mass 9 to memory 11. In some embodiments, VMP unit 8 forwards the predicted evaporation mass to user interface controller 12. In one embodiment, the processor includes control logic 14 that forwards instructions to heating element controller 4. In one embodiment, the method includes activating an alarm unit.
[0102] Calculation of Evaporable Materials – Exemplary Method
[0103] In one embodiment, the amount of steam generated from the evaporable material within the evaporation apparatus (e.g., apparatus 100) can be calculated from the power supplied to the evaporable material and the temperature generated during evaporation. In some embodiments, the amount of steam generated from the evaporating material can be calculated as a function of the energy consumed during evaporation and the temperature generated. That is, the power consumed by the power supply (e.g., power supply 230) set by the heater controller (however, in some variations it can be measured from the heater or the power supply) and the temperature of the evaporating material (e.g., within chamber 32) measured by a temperature sensor (e.g., temperature sensor 250) can be used to determine the amount of steam generated and / or drawn in.
[0104] In some implementations, the total mass of evaporation can be predicted or determined based on Equation 1:
[0105]
[0106] Where Δm 蒸汽,累计 P is the total mass evaporated during the sampling intervals i=1 to i=n, where each interval is a fixed time increment; i The power supplied during interval i; a, b, and c are constants; T i It is the temperature reading at interval i; T i-1This is the temperature reading of the interval immediately preceding the current interval (i-1 preceding interval i). Note that in some variations, the temperature can be relative to room temperature (or the starting temperature) and can be expressed as T. i '(e.g., T) i '、T i-1 'wait).
[0107] Another way to express this relationship is to describe it as follows:
[0108]
[0109] In this example, different coefficients (e.g., d, e) can be used; using a microcontroller, the expression can be implemented more simply than Equation 1 because it has fewer of the required arithmetic functions, but it is mathematically equivalent.
[0110] The coefficients a, b, and c can reflect physical constants whose values can be determined experimentally and vary depending on the evaporable material used. For example, constants a, b, and c can depend on the latent heat and specific heat of the material being evaporated. These constants can further depend on the total mass of the system requiring heating (e.g., liquid material and heater, such as a core and coil). In one exemplary embodiment described below, a equals 0.025, b equals 367, and c equals 30. In another embodiment, a can equal 0.18, b can equal 2000, and c can equal 50. These constants can be determined empirically or based on theoretical values derived from understanding the dimensions and material properties of the evaporable material and heater.
[0111] For example, in some implementations, coefficients a, b, and c can be determined by collecting data and running mathematical algorithms. For example, an analytical inhalation or smoking machine can be used to test the evaporation device under one or more conditions. Total particulate matter (TPM) can be collected from the evaporation device using an analytical inhalation or smoking machine. In some cases, TPM can be collected on a filter pad. The filter pad can be weighed before and after collecting TPM on it, thus determining the weight of TPM on the filter. In some implementations, the empirical determination of a, b, and c is achieved by measuring power and temperature during a series of suction periods and measuring the cumulative mass lost by the device for those suctions using gravimetric analysis. The mass lost by the device is considered equal to the total delivered mass of TPM (mg). The optimal values of a, b, and c are then determined by fitting the above equation to experimental mass delivery, power, and temperature data. Adjustments can be made to constants (e.g., a, b, c or a, d, e) to accommodate variations in device type and formulation type.
[0112] The following describes an example of a method for determining the value of the constant, which is related to the mass of the discharged vapor, the power applied to evaporate the material during a specific time interval (e.g., a portion of the suction), and the temperature of the material before and after evaporation during said period. In this example, the apparatus may first be weighed. Then, a series of suctions may be performed, recording the power (e.g., sampling frequencies are, for example, 20 Hz, 5 Hz to 100 Hz, 5 Hz to 200 Hz, etc.) and the temperature during the test, and then the apparatus may be weighed again. This may be repeated many times (e.g., more than 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100, 120, 150, 200, etc., or 5 to 1000, 10 to 500, 10 to 200, etc.) to achieve a sufficiently large dataset. In one example, the process is repeated 29 times. The m_vapor of each sample can then be calculated by subtracting the final mass from the initial mass. Alternatively, the mass of the steam can be measured directly, for example, by applying steam to a filter pad and using the change in the mass of the pad to obtain m_steam; this may be less accurate because some steam may pass through the pad or deposit on other surfaces. For simplicity of gravimetric analysis, the measuring device is preferred.
[0113] Then, after collecting all the data, the constants can be solved using the m_steam estimate and a set of temperature and power values for each sample over the duration. For example, in equation (1), the constants a, b, and c can be determined from the data. Alternative expressions for the equation can be used (e.g., see equation 2 described below). For example, the values of a, b, and c can be determined such that SUM[t=1 to t=n](aP-b(T) can be solved. i -T i-1 )-cT i The goal is to find the best fit for the measured m_steam for each sample. As mentioned, this can be done for any expression of the measured steam mass, applied power, and temperature. In some variations, this can be done using the gradient descent algorithm to fit the data to a suitable equation. Gradient descent can be beneficial because it is computationally easy to find the optimal values of the constants (e.g., a, b, and c) that minimize the error. However, any suitable curve fitting algorithm or method can be used. In this first example, three different constants are fitted to a fairly large dataset.
[0114] In some implementations, the time interval i (e.g., a partial dose interval) can be from 20 ms to 200 ms (e.g., less than 200 msec, 180 msec, 150 msec, 120 msec, 100 msec, 90 msec, 80 msec, 70 msec, 60 msec, 50 msec, 40 msec, 30 msec, 20 msec, 10 msec, etc.). Temperature and power measurements can be performed at frequencies from 5 to 50 Hz, for example, from 10 to 30 Hz, such as at approximately 20 Hz.
[0115] Typically, power can refer to the power delivered to heat the evaporable material (e.g., in some variations, the power applied to the heater by a heater controller) to evaporate the evaporable material. The applied power can be read directly from the heater controller (e.g., watts, joules, joules per second). 2 Power (Volts*Volts, Volts*Volts / resistance, etc.) and / or can be detected, for example, using any suitable power sensor (voltmeter, Hall effect sensor, inductive sensor, direct measurement sensor, voltage response measurement sensor, etc.). Power can be detected immediately before or during a time interval (e.g., a partial dose interval), representing the power used for evaporating the material during that interval. For example, the power used to determine the partial dose can be transferred from the heater controller while simultaneously supplying power to the heater; in some variations, the power (P... i The power (Pi) is the power applied during the interval immediately preceding interval i (e.g., i-1), because this power is subsequently absorbed by the evaporable material during the measured dose interval. Alternatively, the power (Pi) can be the power detected directly or indirectly during the relevant dose interval (i).
[0116] Similarly, the measured temperature can be within a partial dose time interval (T0). i The temperature of the evaporable material evaporated during the dosing interval. This can be detected directly or indirectly during the dosing interval, at the beginning and / or end. For sufficiently short intervals, this distinction may be irrelevant. The temperature of the evaporable material evaporated before a portion of the dosing interval can refer to the temperature of the immediately preceding interval (e.g., T). i-1 The temperature can also be the temperature at the beginning, end, or during a previous time interval. Alternatively, in some variations, the temperature of the evaporable material evaporated before a partial dose time interval can refer to the temperature of the material evaporated immediately before the application of Pi (e.g., at the start of power application or just before the start of power application); the temperature of the evaporable material evaporated during a partial dose time interval can refer to the temperature of the material at the end of the power application interval.
[0117] Typically, the temperature and power applied to the material to be evaporated refer to the temperature and power applied to a portion of the material rather than the bulk of the material to be evaporated (e.g., in some variations, the material on the core), which will eventually be transformed into vapor material, for example, near the surface, by the application of energy.
[0118] In some embodiments, temperature and power readings are collected only when user suction is detected, for example, via suction sensor 270. Therefore, detection of user suction can activate the microcontroller to begin calculating the amount of steam drawn in, while detection of the end of user suction can cause the microcontroller to stop calculating the amount of steam drawn in. Thus, in some embodiments, Equation 1 can be integrated over the duration of suction. In other embodiments, measurements can be taken and integrated continuously over the duration of device operation. In yet another embodiment, the integration time period can be preset or selected by the user.
[0119] In some implementations, the TPM can be adjusted to determine the total amount of a specific compound inhaled, such as the total amount of an active ingredient (e.g., nicotine). For example, as further described below, the TPM can be multiplied by the percentage of the active ingredient in the evaporable material.
[0120] Figure 10 This first method illustrates the determination of steam dosage within a specific time interval, as just described. For example, in... Figure 10 In this context, the time period (t) used to initially set or begin determining the dosage can be set. p1000. The start of the time period may be triggered by the user, physician or other party (e.g., manually), or it may be started automatically, for example, when the user begins to aspirate on the vaporizer (e.g., using a suction sensor). The duration of the time period can also be predetermined (e.g., fixed, such as 2 seconds, 3 seconds, 4 seconds, 5 seconds, 6 seconds, 7 seconds, 8 seconds, 9 seconds, 10 seconds, 11 seconds, 12 seconds, 13 seconds, 14 seconds, 15 seconds, 16 seconds, 17 seconds, 18 seconds, 19 seconds, 20 seconds, 25 seconds, 30 seconds, 35 seconds, 40 seconds, 45 seconds, 50 seconds, 55 seconds, 60 seconds, 1.5 minutes, 2 minutes, 3 minutes, 4 minutes, 5 minutes, 10 minutes, 12 minutes, 15 minutes, 20 minutes, 30 minutes, 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 7 hours, 8 hours, 9 hours, 10 hours, 11 hours, 12 hours, etc.), or it can be variable, including being set by the user, or it can be determined by detecting the end of aspiration. In some variations, the time period is set as the start of a session, thereby determining the total dose for the entire session, which may include multiple aspirations. In some variations, each aspiration is considered a time period (e.g., using aspiration sensors); the dose of each aspiration can be determined, or the doses during all aspirations in a session can be totaled (where a session can be defined as within a specific time window, such as 5 minutes, 10 minutes, 20 minutes, 30 minutes, 1 hour, 2 hours, etc.).
[0121] The time period typically comprises multiple time intervals i (also referred to herein as partial dose time intervals), which divide time into discrete sampling periods from which partial doses can be calculated. The number (n) of time intervals may be predetermined when the time period is fixed, or it may be open (e.g., continuously increasing). The duration of the time intervals may be fixed or variable, however, they are typically fixed. The duration may be, for example, from approximately 200 msec to approximately 10 msec. The time intervals may be adjacent to each other (e.g., in real time), or they may be separated by off-periods. The time intervals are generally considered to be sequential.
[0122] For each time interval, a partial dose of the evaporable material (e.g., vapor, including any active ingredient) can be calculated. As described above, this can be controlled and / or performed by the evaporation dose predictor (e.g., VMP unit) portion of the device (or in communication with the device). During each time increment i, the device can store the temperature T of the heater and / or the evaporable material near the heater from the previous time interval. i-1 1010. This temperature value (T) i-1This can reflect the temperature of the material being evaporated during the time interval and therefore can be the temperature at the start of the time interval (or just before it begins). During each time interval, the device controls the power 1020 applied to the heater in that interval (i). Note that when no power is applied to the heater, the power value can be zero; steam may still be generated if the heater is still at a temperature different from the previous time increment (i-1), and if not, very little steam may be generated. The power controller (heater controller) can transmit the power that results in being delivered to the heater to the evaporation dose predictor.
[0123] The device can also operate at time intervals (T) i During this process, the temperature of the heater and / or the evaporable material to be evaporated (e.g., material near the heater) is transmitted to the evaporation dose predictor 1030.
[0124] The system can then determine (e.g., using an evaporative dose predictor) a partial dose estimate 1040 for the current time interval i, using the power applied to the heater and the temperature immediately preceding the interval (T). i-1 ) and the temperature during the interval (T) i For example, equations 1 or 2 discussed above can be implemented by an evaporative dose predictor. Partial dose estimates can be combined with any information (P...). i 、T i Storing these values together (e.g., separately as discrete data, or added to the cumulative dose for the time period, or both). The evaporative dose predictor may include one or more memories (e.g., memory registers) for storing these values (note that T in the current interval...). i It can become T during the next interval. i-1 ).
[0125] At the end of each time interval, the device can check whether the end of the time interval has been reached, either because a predetermined number (n) intervals (i = n) have been reached, or because of some other triggering event (e.g., the end of aspiration, the end of a session, etc.), or both. If not, the system can proceed to the next interval, increasing the interval (i = i + 1) by 1050. Once the end is reached, in some variations (e.g., the accumulator register is not saved), all partial doses can be summed 1060. Note that in any of these variations, this step of summing all partial doses can be performed continuously, for example, accumulating (summing) them as each new interval passes. Therefore, the step of summing the calculated partial doses in the evaporation dose predictor unit to determine the total dose of steam delivered during the time interval can be completed at the end of the time interval, or during the time interval because the partial doses have been determined.
[0126] example
[0127] Figure 2 and Figure 3 This shows the relationship between the TPM predicted using Equation 1 and the actual TPM readings using an inhaler or smoke machine. Figure 2 The graph shows the relationship between the predicted TPM (solid line) and the measured TPM (point) in the machine test. In this test, R-squared is 0.78.
[0128] In order to collect Figure 2 and Figure 3 Data was collected using an electronic evaporator unit equipped with a separate, detachable chamber containing evaporable material to construct an inhalation or smoking machine. Two units were connected in series. Temperature and power measurements were collected. Ten inhalations were performed using the inhalation or smoking machine (at 55 cc / 3 sec). Mass loss (or TPM loss) was measured every 10 inhalations. Thirty-one sample readings were collected using two prototype electronic evaporator units and four prototype chambers. The collected power and temperature data were analyzed. The power and temperature data were compared with the actual measured mass loss data to correlate the evaporation rate with energy consumption and temperature. Findings were made in R... 2 When the value is 0.78, 29 (29) samples are within ±15%, and the remaining two (2) samples are within ±17%. Figure 2 This displays a graphical relationship between predicted and measured total particulate matter (TPM) values. Figure 3 This displays the complete dataset of predicted values relative to the actual readings.
[0129] exist Figure 2In the example shown, by executing the evaporation mass prediction formula according to Equation 1 described herein, a tabular and graphical relationship between the predicted TPM (mg) and the actual TPM (mg) can be established. The evaporation mass prediction formula can be used to create a program that can be utilized by the VMP unit. These values can be transmitted to a calibration device via wireless or wired data transmission, more preferably directly embedded in the evaporation device itself. Figure 2 The results of the smoking experiment shown can provide information to the user or other individual and allow them to control the amount of evaporable material associated with TPM levels.
[0130] Figure 2 and Figure 3 The results show that Equation 1 can advantageously improve inconsistencies that arise when the function is fitted and / or when it is assumed that the aspiration duration and / or power can be correlated with mass removal.
[0131] Smoking tests on human subjects were also conducted using an electronic vaporizer device equipped with a separate, detachable chamber containing vaporizable material. Criteria for human subjects included voluntary participation of users who were regular or habitual smokers or vapers, and diversity in smoking patterns or random vaping habits. Participants were asked to vape normally, and a wide variety of vaping behaviors were observed from different subjects, and even between different vaping sessions of the same subject. Therefore, the vaping properties of participants were variable and ranged from 1 to 5 mg per vaping session; for example, some subjects consistently vaped at approximately 3 mg, while others vaped at 2 mg on one session and 4 mg on the next. Figure 4 The table shows the measured TPM in human trials. The first column shows the percentage error from the target (40 mg). The second column shows the mean error, which can be used as a metric for further adjustments to the evaporation mass prediction formula. The formulation of the evaporable material in the proprietary chamber can contain 40 mg of total liquid, which can correspond to 2 mg of nicotine (5% wt nicotine). The test demonstrates that the device calibration can accurately dispense the dose, which can be a specific dosing dose. In this paper, the smoking test was conducted with eleven human subjects. Twenty-three sample readings (or results) were within ±15% of the 40 mg target. Two additional samples were within ±17%. The mean of the samples was 42.1 mg. The coefficient of variance was 5.96%. All samples were within ±11% of the mean.
[0132] In some implementations, measuring only the duration of suction can lead to inaccurate quantification of the evaporation mass. Figure 5 and Figure 6 The graph shown is correlated with TPM as a function of power, time, and temperature. When performing the evaporation mass prediction method described in this paper, a relationship between TPM (mg) as a function of power, time, and temperature can then be established.
[0133] On the one hand, Figure 5 and Figure 6 This disclosure describes a real-time graphical program for collecting the mass of evaporation (mg) as a function of power, time, and temperature. Figure 5 and Figure 6 In the middle, the thickest lines 501 and 501' (marked with temperature) represent the resistivity ratio (R). 加热器 / R 参考 The value is given and is proportional to the heater temperature (shown as subtracted from 1); for example, this can be multiplied by 1 / TCR to convert to units (e.g., °C). Therefore, when calculating the dosage, the temperature (T) is determined for each interval. i and T i-1 The measured resistance of the coil is denoted as , while the baseline is the baseline resistance (set separately from the heater, assumed to be at room temperature). The temperature rise and the temperature rise above room temperature have a linear relationship with a coefficient of 1 / TCR, where TCR is the temperature coefficient of resistance. Figure 5 and Figure 6 In the diagram, the medium-thickness wires 502 and 502' (labeled as power) represent the power delivered to the coil (e.g., in watts). Furthermore, in... Figure 5 and Figure 6 Of the two, the thinnest lines 503 and 503' (labeled as evaporation rate) represent the evaporation (vaporization) rate, expressed in mg / msec in this example. This can be derived by performing the formulas expressed in Equations 1 or 2 previously discussed. The values in this example can be divided by 50 ms / sample (interval time) to obtain mg / msec instead of mg / sample. The curve can be integrated over the aspiration time course to obtain the total dose delivered from the aspiration. Figure 5 and Figure 6 In the diagram, the left-hand axis is scaled differently for power, temperature, and evaporation rate. Figure 5 and Figure 6 Examples of suction performed under two different predetermined suction distributions are shown. Figure 5 During the procedure, approximately 35cc of aspirate was extracted within 3 seconds. Figure 6 In the middle, 70cc of aspirate was extracted in about 3 seconds, of which Figure 6 The flow velocity in is Figure 5 Twice that of the middle. Illustratively, by comparison... Figure 6 and Figure 5 , Figure 6Faster suction results in higher mass removal (mass evaporation). Different suctions evaporate different amounts of material. This disclosure shows that the system responds to different suction distributions (which typically do not have a uniform flow rate during suction) and the duration can vary. This behavior can be further supported by human studies that have yielded consistent results, even though the suction properties of individual or unique human suctions differ.
[0134] Calculation of Evaporable Materials – A Second Exemplary Method
[0135] In some implementations, an evaporation device such as device 100 can be calibrated based on previous measurements taken using the same or similar apparatus, thereby allowing the amount of material to be evaporated to be determined based on the performance of said same or similar apparatus. For example, the apparatus can be calibrated using a function fitting method to determine the relationship between the total particulate matter (TPM) release content (mg) and one or more evaporation parameters of the atomized material from said apparatus.
[0136] In some cases, methods for calibrating the device to obtain the active material content from the relationship between total particulate matter (TPM) release (mg) and evaporation parameters of the atomizing material may include: setting functional operating parameters of the analytical inhaler or vaping machine, and testing the device under one or more conditions. In some cases, the conditions that may vary may include aspiration volume and / or flow rate. The conditions (e.g., evaporation parameters) may include one or more variables selected from aspiration duration (sec), aspiration volume (ml), flow rate (ml / sec), power (watts), and voltage (volts). In some cases, exemplary ranges include, but are not limited to, 1 mL–100 mL volume; 0.2 s–10 s duration; 2100 mL / s; 2.5–4.2 V.
[0137] Total particulate matter (TPM) can be collected from the electronic evaporator device. In some cases, TPM can be collected on a filter pad. The filter pad can be weighed before and after collecting TPM on the filter, thus determining the weight of TPM on the filter. In some cases, the weight of the filter can be tare. The weight of the material to be evaporated in the device can be recorded before evaporation. In some cases, the weight of the evaporable material in the device can be measured and recorded before operating the device. The weight of the evaporable material in the device can be measured and recorded after one or more suctions on the device. The weight difference of the evaporable material between the initial weight and the weight after one or more suctions can be compared with the weight of TPM collected on the filter. In some cases, the weight difference of the evaporable material between the initial weight and the weight after one or more suctions can be substantially the same as the weight of TPM collected on the filter. The TPM collected on the filter may include material evaporated from the evaporable material in the device during one or more suctions.
[0138] In some cases, the analytical inhalation or smoking device can be a machine configured to simulate the inhalation of evaporated material by a human from an evaporation device. When the machine smoking device evaporates the formulation in one or more devices, the TPM from the device can be collected onto one or more filter pads. Each device can collect the TPM released from the electronic evaporator device onto a different filter pad. For each filter pad, the amount of TPM released by the device can be determined. The amount of TPM released by a single device relative to the initial weight of the evaporable material can be calculated. In some cases, this step can be repeated with variable inhalation conditions, such as gradually increasing and / or decreasing the inhalation duration (seconds) of the machine inhalation or smoking device. In some cases, this step can be repeated with different inhalation volumes (ml) of the machine smoking device. The inhalation volume can vary in the range of 1 mL to 100 mL, more preferably 20 to 80 mL, and most preferably 30 to 60 mL. In some cases, this step can be repeated with varying flow rates of the machine smoking device. The flow rate of the machine inhalation or smoking device can be varied in the range of 2-100 mL / s, more preferably 5-50 mL / s, and most preferably 10-30 mL / s. In some cases, this step can be repeated with different power levels of the machine inhalation or smoking device. The power (watts) of the smoking device can be varied in the range of 2 watts-20 watts, more preferably 3 watts-8 watts. In some cases, this step can be repeated with different voltage levels of the machine inhalation or smoking device. The voltage of the device can be varied in the range of 2.5-4.2V, more preferably 3.0-4.2V.
[0139] The suction volume and the corresponding TPM release (mg) can be listed in a table. The relationship between suction volume and the corresponding TPM release (mg) can be graphical and / or displayed in a table, and can be used to predict, determine, or estimate the amount of vapor consumed by the user when using the device. For example, Figure 9A and 9B Exemplary lookup tables and graphs are shown, which can be used to determine or estimate the amount of vapor inhaled by a user based on calibration data previously collected from an inhalation or smoking machine. These values can be transmitted to a device, such as a microcontroller within the PCB 240 of device 100, via wireless or wired data transmission. Figure 9A and 9B The results of the calibration experiments shown can inform users or other individuals and allow them to understand or control the amount of active material associated with TPM levels.
[0140] Evaporation quality predictor unit
[0141] Evaporator devices such as devices 10, 100, and 100' may include an evaporation quality predictor (e.g., a VMP unit), for example, within control units 10 and 110. VMP 109 may execute the logic described herein to determine the dose delivered according to any method described herein. In some embodiments, the VMP is communicatively coupled to one or more of the following: a suction sensor (optional), a heater (e.g., a heating element) controller, an alarm unit, and / or control logic. In some embodiments, the VMP unit is communicatively coupled to a suction sensor, a timer, a heater controller, and an alarm unit or control logic. In some embodiments, the VMP includes software (e.g., a software module or control logic) running on a processor. The VMP unit may integrate: a power reading from the heater controller, a temperature reading from a temperature sensor; and, in some cases, a suction duration or suction frequency reading from the suction sensor and timer. The VMP unit then calculates how much vapor has been evaporated from the evaporable material.
[0142] In some implementations, the VPM unit of each device can be calibrated separately. In some implementations, the VPM calibration can be set based on known evaporating materials. In some implementations, the device may include a user interface that allows the user to input the material to be evaporated, which in turn sets constants a, b, c for Equation 1 and / or function fitting curves or lookup tables.
[0143] In some implementations, the VMP (or another component of the controller) can calculate the active material content based on the total concentration (TPM). The TPM can be correlated with the active material content based on the composition of the organic material loaded into the electronic evaporator device. For example, an organic material containing 20-25% active material would be correlated with the TPM (mg) of that percentage of active material. In some cases, assuming the total conversion rate (atomization) of the active material may be reasonable.
[0144] In some embodiments, the VMP unit is user-adjustable and allows the user to preset the amount of evaporable material to be evaporated before the user is warned, or before components of the evaporator unit are deactivated, or before control logic is executed. In some embodiments, the VMP unit then activates an alarm unit that alerts the user when the preset amount of evaporable material has evaporated. In some embodiments, the VMP unit then deactivates the evaporator unit when the preset amount of evaporable material has evaporated. In some embodiments, the VMP is user-adjustable, such that the evaporator unit evaporates a target amount of material in a single suction cycle.
[0145] In some embodiments, the VMP is user-adjustable, allowing the evaporator unit to evaporate a target amount of material in multiple suctions. In some embodiments, the VMP is user-adjustable, allowing the evaporator unit to evaporate a target amount of material in a single suction. In some variations, the VMP is user-adjustable, allowing the unit to be deactivated for a period of time after the target amount of material has been evaporated. The VMP may be user-adjustable, allowing the unit to activate an alarm after the target amount of material has been evaporated. In some embodiments, the VMP activates an alarm when the amount of evaporable material in the evaporator unit falls below a preset threshold. In some embodiments, the VMP unit is communicatively connected to a memory unit and stores multiple measurements of any of the following: power, temperature, suction duration readings, or any combination thereof. In some embodiments, the VMP unit calculates the cumulative amount of evaporated evaporable material. If, for example, the user does not completely evaporate the preset limit in a single suction, the VMP unit tracks the amount of evaporable material evaporated in multiple suctions. In some embodiments, the VMP unit is a software module. In some embodiments, the VMP unit is a microprocessor. In some implementations, the VMP unit generates a suction distribution that tracks power, temperature, pressure, or a combination thereof over time.
[0146] In some embodiments, the accuracy of the evaporative TPM measured from the VMP unit is at least ±25% of the predicted value. In some embodiments, the accuracy of the evaporative TPM measured from the VMP unit is at least ±20% of the predicted value. In some embodiments, the accuracy of the evaporative TPM measured from the VMP unit is at least ±15% of the predicted value. In some embodiments, the accuracy of the evaporative TPM measured from the VMP unit is at least ±10% of the predicted value. In some embodiments, the accuracy of the evaporative TPM measured from the VMP unit is at least ±5% of the predicted value. In some embodiments, the VMP unit is a software component associated with a processor.
[0147] In some embodiments, the preset amount of material allowed to evaporate before the VMP unit activates the alarm is adjustable. In some embodiments, the preset amount of material allowed to evaporate before the VMP unit activates the control logic is adjustable. Adjustment allows the user to be alerted when a certain amount of evaporable material has evaporated and been inhaled, thus improving the user experience by precisely controlling the dosage of the evaporable material (e.g., nicotine, cannabinoids). In some embodiments, the user can preset the amount of evaporable material to be evaporated in mg TPM. In some embodiments, the preset amount of evaporable material to be evaporated in mg TPM is approximately 1 mg to approximately 1000 mg.

In some embodiments, the preset amount of evaporable material to be evaporated, in mg TPM, is approximately 10 mg. In some embodiments, the preset amount of evaporable material to be evaporated, in mg TPM, is approximately 20 mg. In some embodiments, the preset amount of evaporable material to be evaporated, in mg TPM, is approximately 30 mg. In some embodiments, the preset amount of evaporable material to be evaporated, in mg TPM, is approximately 40 mg.In some embodiments, the preset amount of evaporable material to be evaporated, in mg TPM, is approximately 50 mg. In some embodiments, the preset amount of evaporable material to be evaporated, in mg TPM, is approximately 60 mg. In some embodiments, the preset amount of evaporable material to be evaporated, in mg TPM, is approximately 70 mg. In some embodiments, the preset amount of evaporable material to be evaporated, in mg TPM, is approximately 80 mg. In some embodiments, the preset amount of evaporable material to be evaporated, in mg TPM, is approximately 90 mg. In some embodiments, the preset amount of evaporable material to be evaporated, in mg TPM, is approximately 100 mg.
[0148] In some embodiments, the user can preset the amount of vaporizable material to be evaporated, calculated in mg of active ingredient (e.g., nicotine, cannabinoids, THC). In some embodiments, the preset amount of vaporizable material to be evaporated, calculated in mg of active ingredient, is from about 1 mg to about 1000 mg.

[0180] Heated reservoirs allow for a more controlled initial state, which can enhance the predictability of dose estimation. This is in Figure 8 This will be explained in more detail. In some variations, particularly those described above, heating the reservoir may be unnecessary because a sufficiently accurate dose (steam) estimate can be determined.

[0181] Using electronic evaporator devices to aspirate evaporable organic formulations that may be viscous (non-flowing) or non-liquid can be challenging. However, there remains an unmet need to evaporate organic formulations that are viscous (non-flowing) liquids or non-liquids. In some embodiments, the heat reservoir is distinct from the heating element. In some embodiments, the heat reservoir is fluidly coupled to the heating element. In some embodiments, the heat reservoir is constructed of stainless steel. In some embodiments, the heat reservoir is constructed of high-temperature plastic.

In some embodiments, the heat block is configured for heating materials exhibiting a viscosity of 1000 to 5000 centipoise. In some embodiments, the heat block is configured for heating materials exhibiting viscosities of 5000 and 50000 centipoise.

[0182] In this example, an analytical evaporator device is used, similar to machines known in the art. An electronic evaporator device including a heat storage tank for viscous (non-flowing) liquids or non-liquids is compared to an electronic evaporator device without a heat storage tank. The heat storage tank preheats the viscous (non-flowing) liquid or non-liquid. When the viscous (non-flowing) liquid or non-liquid is preheated before evaporation, the effects of uneven heating during evaporation are reduced. Figure 8The displayed graphical data compares the number of extractions relative to the TPM release content (mg) of an unheated reservoir in an electronic evaporator device with the number of extractions relative to the TPM release content (mg) of a heated reservoir in the same device, where the latter reservoir is preheated to a temperature of 40-60°C. With the reservoir preheated to 40-60°C, approximately consistent amounts of TPM (mg) are produced from viscous or non-flowing organic formulations, whereas the amount of TPM (mg) evaporated by an electronic evaporator device without a heated reservoir is inconsistent. This inconsistency in TPM produced by the unheated reservoir may be a result of uneven heating of the evaporable material.

Furthermore, any optional features of the described variations of the invention may be set forth and claimed independently, or in combination with any one or more features described herein. Similarly, references to a single item include the possibility that multiple identical items exist. More specifically, the English singular forms “a,” “an,” “said,” and “the,” as used herein and in the appended claims, include plural indicators unless the context clearly specifies otherwise. It should also be noted that the claims may be designed to exclude any optional elements. Therefore, this statement is intended as a basis for the use of exclusive terms such as “solely,” “only,” etc., in relation to the assertion of claim elements or the use of “negative” limitation. Unless otherwise defined herein, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The scope of this invention is not limited by this specification but is defined only by the obvious meaning of the terms used in the claims.
[0201] When a feature or element is referred to herein as being “on” another feature or element, it may be directly on the other feature or element, or there may be intermediate features and / or elements present. In contrast, when a feature or element is referred to as being “directly on” another feature or element, there are no intermediate features or elements. It will also be understood that when a feature or element is referred to as being “connected,” “attached,” or “joined” to another feature or element, it may be directly connected, attached, or joined to the other feature or element, or there may be intermediate features or elements present. In contrast, when a feature or element is referred to as being “directly connected,” “directly attached,” or “directly joined” to another feature or element, there are no intermediate features or elements. While described or shown with respect to one embodiment, features and elements so described or shown can be applied to other embodiments. Those skilled in the art will also understand that a structure or feature referring to being “adjacent” to another feature may have portions overlapping with or beneath the adjacent feature.
[0202] It will be further understood that, when used in this specification, the terms “comprising” and / or “including” specify the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, or groups thereof. As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items and may be abbreviated to “ / ”.
[0203] Spatial relative terms such as “under,” “below,” “lower,” “over,” “upper,” etc., may be used herein to describe the relationship of one element or feature to another, as illustrated in the figures. It should be understood that spatial relative terms are intended to include different orientations of the device in use or operation other than those shown in the figures. For example, if the device in the figures is inverted, what is described as “under” or “below” other elements or features is “over” for other elements or features. Thus, the exemplary term “under” can include the vertical direction. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptors used herein are interpreted accordingly. Similarly, unless otherwise specified, the terms “up,” “down,” “vertical,” “horizontal,” etc., are used for illustrative purposes only.
[0204] Although the terms "first" and "second" can be used to describe a variety of features / elements (including steps), these features / elements should not be limited by these terms unless the context otherwise requires. These terms can be used to distinguish one feature / element from another. Thus, the first feature / element discussed below may be referred to as the second feature / element, and similarly, the second feature / element discussed below may be referred to as the first feature / element, without departing from the teachings of the invention.
[0205] In this specification and the claims below, unless the context requires otherwise, the word “comprising,” and variations such as “including” and “containing,” means that multiple components may be used together in a method and article of manufacture (e.g., a composition and an apparatus that includes means and methods).

[0206] As used herein and in the claims, including as in the embodiments, unless otherwise expressly stated, all numbers may be interpreted as if they begin with “about” or “approximately”, even if the term is not explicitly stated. The phrase “about” or “approximately” may be used when describing size and / or location to indicate that the described value and / or location is within a reasonably expected range of value and / or location. For example, a numerical value may have values of + / - 0.1% (or a range of values), + / - 1% (or a range of values), + / - 2% (or a range of values), + / - 5% (or a range of values), + / - 10% (or a range of values), etc. Any numerical value given herein should also be understood to include approximately or approximately that value unless the context otherwise indicates. For example, if the value “10” is disclosed, “about 10” is also disclosed. Any numerical ranges described herein are intended to include all subranges included herein. It should also be understood that, as will be properly understood by those skilled in the art, when a value is disclosed, values “less than or equal to the value,” “greater than or equal to the value,” and possible ranges between values are also disclosed. For example, if “X” is disclosed, then “less than or equal to X” and “greater than or equal to X” are also disclosed (e.g., where X is a numerical value). It should also be understood that throughout the application, data is provided in various different formats of numbers, and this data represents a range of arbitrary combinations of start and end points and data points. For example, if specific data point “10” and specific data point “15” are disclosed, then it should be understood that greater than, greater than or equal to, less than, less than or equal to, equal to 10 and 15, and 10 to 15 are considered disclosed. It should also be understood that each unit between two specific units is also disclosed. For example, if 10 and 15 are disclosed, then 11, 12, 13, and 14 are also disclosed.
[0207] Although various illustrative embodiments have been described above, any of the various modifications to these embodiments may be made without departing from the scope of the invention as set forth in the claims. For example, in alternative embodiments, the order in which the various described method steps are performed may often be changed, and in other alternative embodiments, one or more method steps may be skipped entirely.
