[0013] Vaporizers have become increasingly popular for the consumption of various precursor compositions, particularly those derived from cannabis and tobacco. These devices offer a smokeless alternative to traditional smoking methods, potentially reducing harmful byproducts and providing a more controlled delivery of active compounds.

[0014] Vaporizers may rely on heating elements to directly vaporize the precursor composition, which may sometimes lead to uneven heating and inconsistent vapor quality. Moreover, these devices may result in dry or harsh vapor that can be uncomfortable for users. Additionally, vaporizers may not efficiently separate unwanted particles from the aerosol, potentially affecting the purity and taste of the inhaled product.

[0015] The vaporizing device presented herein aims to overcome the limitations of existing vaporizers by providing a device that utilizes suction to draw gas into the vaporizer and percolate gas through a liquid. This process conditions the gas by filtering out particles, humidifying the gas, and normalizing the temperature of the gas. The conditioned gas may be then directed through a chamber assembly equipped with a heat source, which vaporizes the precursor composition held in a reservoir. The heat source may comprise an infrared (IR) and/or ultraviolet (UV) light emitter. The IR and/or UV light from the emitter may be absorbed by the precursor thereby heating the precursor. The precursor may be IR and/or UV light absorptive. The precursor may be doped to make and/or enhance the IR and/or UV light absorption characteristics of the precursor. The UV light may help sterilize the precursor and/or the chamber. The chamber assembly includes features to enhance the mixing and aerosolization of the precursor compounds and selectively removes particles from an aerosol by modifying velocity and pressure of the flow. The vaporizing device presented herein also incorporates a heat exchanger system within the liquid container, ensuring efficient thermal regulation of the aerosol before the aerosol may be inhaled. This may result in a high-quality, smooth, and consistent inhalation aerosol, providing an improved user experience.

[0016] Figure 1 is a block diagram of vaporizing device 100. Vaporizing device 100 may generate an inhalable aerosol for delivery to a user. As shown, vaporizing device 100 comprises filtration and scrubbing unit 110, reaction chamber 120, reservoir 130, heater 140, control system 150, intake gas particle size selection system 162, aerosol particle size selection system 164, condenser 170, and mouthpiece 180 which may work together to reduce contamination, normalize particle sizes, and maintain optimal temperature and humidity conditions for the aerosol. [0017] Filtration and scrubbing unit 110 may be positioned upstream of reaction chamber 120. The primary body of intake gas filtration and scrubbing unit 110 may comprise a liquid-tight volume. Forcing intake gas through a liquid medium contained within intake gas filtration and scrubbing unit 110 may serve to scrub or filter an intake gas of particles. In some embodiments, this process may also scrub and solvate elements in the intake gas stream, while simultaneously conditioning the intake gas by normalizing its temperature and humidity before it enters reaction chamber 120. The liquid medium may comprise water or another suitable substance, such as a humectant (e.g., vegetable-based glycerol). Filtration and scrubbing unit 110 may be coupled to a particle size selection system, such as intake gas particle size selection system 162.

[0018] In an embodiment, filtration and scrubbing unit 110 may include an intake configured to draw an intake gas from the exterior of filtration and scrubbing unit 110 and deliver said intake gas to a liquid contained by filtration and scrubbing unit 110. It may be desirable to create a turbulent, non-laminar flow of intake gas within the liquid to increase the dwell time of intake gas in the liquid. In an embodiment, an intake may include a gas flow port that allows for control and shape of an intake gas orifice, such as a valve, for user control over intake gas volume and velocity entering the liquid medium. For example, said intake could be equipped with a spring-loaded valve configured to increase a volume of airflow into vaporizing device 100 when pressed.

[0019] Filtration and scrubbing unit 110 may include flow architecture to control an intake gas flow through a liquid medium and may increase transit time by directing a flow of intake gas through mechanical structures along the path of the intake gas and liquid. In some examples, filtration and scrubbing unit 110 may be configured to contain a heat exchanger, such as condenser 170. A flow of intake gas may be forced to transit around condenser 170 increasing dwell time in the liquid and generating dynamic non-laminar flow around condenser 170 to help condenser 170 and a flow of aerosol within it come into equilibrium the liquid and intake gas. Condenser 170 may be positioned within filtration and scrubbing unit 110 to maximize flow interference of an intake gas passing through a liquid medium. [0020] Percolation of intake gas through a liquid can play a significant role in disrupting a thermal boundary layer that forms at the interface between the liquid and condenser 170, thereby enhancing heat transfer. As intake gas percolates through the liquid, it forms bubbles that rise to the surface. Upon reaching the liquid surface, these bubbles may burst, causing localized splashing that results in droplets of liquid being ejected and dispersed onto areas of condenser 170 that are not fully immersed in the liquid. The ejected liquid droplets may accumulate on condenser’s 170 surface and, over time, flow over the surface, eventually dripping down the body of condenser 170. This process of dripping liquid, combined with the enhanced surface contact between the droplets and condenser 170, facilitates improved heat transfer. Furthermore, the interaction between the droplets and the surface of condenser 170 may help to prevent the formation or accumulation of a thermal boundary layer within the liquid. By minimizing the presence of this insulating layer, the overall heat transfer efficiency may be substantially improved, ensuring more effective cooling or heat exchange between the liquid and condenser 170.

[0021] In addition to increasing transit time of an intake gas passing through filtration and scrubbing unit 110, condenser 170 may transfer heat between an aerosol generated in reaction chamber 120 to the interior of filtration and scrubbing unit 110. Heating the interior of filtration and scrubbing unit 110, and a liquid medium contained within, may help to normalize the temperature of an intake gas and aid in a thermally mediated reaction. In an embodiment, heating of an intake gas may serve to facilitate a thermally mediated reaction in reaction chamber 120 such that the heated intake gas may provide some of the required thermal energy for a desired reaction, process, phase change, or similar such thermally mediated or influenced event to occur. In some embodiments, it may be desirable to cool an aerosol passing through condenser 170.

[0022] Filtration and scrubbing unit 110 may be manufactured from materials that are inert, non-reactive, thermally stable, and non-contributory to any reaction with an intake gas, precursor or formed aerosol. In some examples, it may be desirable to manufacture filtration and scrubbing unit 110 from materials having some ability to limit transmission of infrared radiation such as borosilicate.

[0023] Reaction chamber 120 may be positioned downstream of filtration and scrubbing unit 110 and may be configured to generate an aerosol by facilitating a thermally mediated reaction between an intake gas and a precursor held within reservoir 130. Reaction chamber 120 may comprise an interior volume configured to contain reservoir 130 and mix an intake gas with constituents generated from a thermally mediated reaction of precursor. Reaction chamber 120 may be in communication with an inlet for receiving an intake gas and an outlet through which an aerosol exits. Reaction chamber 120 may include an access port allowing a user to place a precursor composition into reservoir 130.

[0024] In some embodiments, reaction chamber 120 may include architecture for control over pressure gradients within the chamber to expose a precursor to a comparatively high velocity, high pressure region. This configuration may reduce the thermal energy required to facilitate a phase change or transition of constituents in a precursor composition into an aerosol. The reduction may occur by increasing the transit time of the gas and precursor composition based on mass, maximizing dynamic flow-mediated exposure to the heated region of reaction chamber 120, and facilitating dynamic mixing or mobilization of the material, thus reducing static exposure to the heating assembly. In an embodiment, reaction chamber 120 may include an adjustable port to control an output flow of aerosol. [0025] In some embodiments, reaction chamber 120 may include architecture designed to generate a vortical rotational flow near reservoir 130. The centrifugal effects of this vortical flow may help disperse the precursor composition held in reservoir 130 into a thin layer. Thermal transfer through this thin layer is more efficient and faster than the en bloc heating as is defined by Q/t = kA((Tl-T2)/l). Where: Q/t is the rate of heat transfer, k is the thermal conductivity of the material, A is the cross-sectional area, T1-T2 is the temperature difference, 1 is the thickness. In this case, the centrifugal rotational flow increases the cross-sectional area and decreases the thickness, thereby improving the efficiency of heat transfer.

[0026] Reaction chamber 120 may be manufactured from materials that are inert, non- reactive, thermally stable, and non-contributory to any reaction with an intake gas, precursor or formed aerosol. In some examples, it may be desirable to manufacture reaction chamber 120 from materials having some ability to limit transmission of infrared radiation such as borosilicate.

[0027] Reaction chamber 120 may be configured to house reservoir 130, which may be primarily cylindrical in shape with a closed bottom and open top for holding a precursor composition. The precursor composition may be heated to a predetermined temperature for a specific duration by heater 140 to enable the reaction and aerosol formation. In one embodiment, the bottom of reservoir 130 may be closed in a conical shape, aligned axially with the cylindrical body. This geometric structure increases the surface area of the closed cylinder, where A=Kr(r+\'(h² +r²) for a circular right cone, and A = it r² for the closed area of a standard cylinder. This increased surface area may improve exposure to the intake gas flow and enhances the heating efficiency of reaction chamber 120. In embodiments where reaction chamber 120 includes flow architecture to generate a vortical rotational flow, the conical structure of reservoir 130 may also act as a companion flow director, working in conjunction with a helical flow director at the gas intake of reaction chamber 120. In an embodiment, the bottom of reservoir 130 may be dome shape. [0028] Reservoir 130 may be positioned in close proximity to heater 140 to optimize heat transfer, while providing a physical barrier to prevent any direct contact between heater 140 and a precursor composition. If heater 140 transfers heat to reservoir 130 through conductive heat transfer, it may be desirable for reservoir 130 and heater 140 to be in direct physical contact. In other embodiments, where heater 140 utilizes radiant energy to heat a precursor composition, direct contact between reservoir 130 and heater 140 may not be necessary. In some embodiments, the bottom of reservoir 130 may incorporate a lens designed to focus one or more of infrared (IR) light/radiation, visible light/radiation, and/or ultraviolet (UV) radiation/light into a precursor composition.

[0029] Heater 140 may be, or comprise an infrared (IR) and/or ultraviolet (UV) light emitter. In an embodiment, the emitter may be or comprise an "electromagnetic emitter”. Thus, in an embodiment, the emitter may comprise a single emitter that may emit infrared, ultraviolet, and visible light (either concurrently and/or in selectable combinations). In an embodiment, the emitter may be or comprise an "incandescent radiator". Thus, for example, the emitter may have an emission spectrum where infrared and UV represent the majority of the emission and visible light represent the minority of the emission. In an embodiment, the emitter may emit a continuous wide spectrum that extends from the near ultraviolet (e.g., from around 350 nm or below) through the visible spectrum. In an embodiment, the emitter may emit with here peak UV emission that is below 400 nm, and infrared emission that is broad and may, for example, peak in the vicinity of 1000 nm. In an embodiment, the emitter may emit a UV spectrum peaks in the vicinity of the 200-3 OOnm range and emits an infrared over a broad range up to around to 9000 nm and may have a peak around 3000nm.

[0030] In an embodiment, the emitter may be, or comprise, a tungsten filament encased in a quartz envelope that is under vacuum (relative to ambient) and surrounded by, for example, a gas such as halogen. In an embodiment, the emitter may be, or comprise, the an LED (light emitting diode) configured to emit in the mid-infrared range. For example, the emitter may be comprise an LED fabricated from narrow band-gap InAsSb/InAsSbP-based heterostructures lattice-matched to InAs substrate for IR emission the 2700-5000 nm spectral range. In an embodiment, the emitter may, or comprise, a semiconductor material configured with a diode structure that has a variable emission spectrum that is based on the forward voltage of the diode. For example, the emitter may be, or comprise, a diode structure that has a bandgap suitable for emitting in the far-infrared region (approximately 3 pm to 1 mm) with a tunable (e.g., by the forward bias voltage to emit with a select peak in the far-infrared. In an embodiment, the emitter may, or comprise, blackbody radiation sources (e.g., heated objects) or nonlinear optical processes for selected or controlled or tuned emission in the far-infrared.

[0031] At least the IR and/or UV light from heater 140 may be absorbed by the precursor composition thereby heating the precursor composition. The precursor composition may be IR and/or UV light absorptive. The precursor composition may be doped and/or formulated to make and/or enhance the IR and/or UV light absorption characteristics of the precursor composition. The UV light may help sterilize the precursor composition and/or the reservoir 130. Thus, in some embodiments, heater 140 may heat the precursor via IR and/or UV radiation without directly heating reservoir 130 and/or reaction chamber 120. [0032] In an embodiment, the UV light excitation of the precursor may facilitate a simultaneous and/or targeted heating and thermal mobilization by infrared emission that increases the efficiency of the infrared emission. For example, the molecular bond vibration induced by the UV emi s si on/ab sorption can be used to induce a bathochromic effect (also known as a red shift), causing the precursor absorption to shift towards longer lower energy wavelengths — thus requiring less infrared energy to heat and thermally mobilize the precursor.

[0033] In some embodiments, the UV and IR emission may occur concurrently. In some embodiments, The UV emission may be initiated before the IR emission. In some embodiments, the IR emission may occur before the UV emission. The IR emission and UV emission may be pulsed concurrently or in alternation.

[0034] The IR emitter may be programmed or otherwise configured to shift the emitted wavelengths to increase the peak wavelength to longer lower energy wavelengths during activation to account for the red shifting of the precursor during mobilization and to decrease the total amount of energy required to thermally mobilize the precursor.

[0035] In an embodiment, the modulation/heating of select precursors via the mixed UV and IR method includes precursors may include one or more of glycerol/glycerine and/or propylene glycol, nicotine, cannabinoids either in their diol form or their acid form (e.g., A9- THC - tetrahydrocannabinol, A9-THCA - tetrahydrocannabinolic acid, and/or CBD - Cannabidiol, CBDA - cannabidiolic acid), and/or as secondary components to the precursor such terpenes. [0036] In some embodiments, nicotine may be heated and thermally mobilized in to an inhalation aerosol by targeting the UV nicotine absorption peak around 260 nm. For example the UV absorption of nicotine that is substantially due to electron transitions in the pyridine ring with infrared absorption with a peak in the 7500 nm. In an embodiment, nicotine may be combined with glycerol and/or propylene glycol and heated and thermally mobilized into an inhalation aerosol by targeting the glycerol and propylene glycol UV absorption that occurs below 210 nm and the UV nicotine absorption peak around 260 nm. Thus, the UV emitter may have a peak, for example, that is below 220 nm to target the sharp absorption range of glycerol thereby facilitating a Charge-transfer-to-solvent (CTTS) transition, where the transitions are a photochemical processes where an electron is transferred from a solute (like an anion) to the surrounding solvent, forming a quasi-bound state and may lead to solvated electrons thus further increasing the energetic state of the precursor. The IR component of the emission may be targeted to peak within the range of 1400-1900nm for propylene glycol and 2900-4000 nm for glycerol. In an embodiment, broad far infrared emission from, for example, 7500 nm - 11,000 nm. With the far IR emission also serving to mobilize terpenes if present in the precursor mixture.

[0037] In an embodiment, acidic forms of the cannabinoids THCA and CBDA are present in the precursor and undergo a thermally mediated decarboxylation reaction (RCO2H

RH + CO2) as part of the process of thermally mobilizing the cannabinoid into an inhalation aerosol by UV and IR emission. The reaction may use heat to convert A9-THCA and CBDA which are inactive when inhaled, into A9-THC and CBD which are active when inhaled, by removing a carboxyl group. In an embodiment, the cannabinoids are heated and thermally mobilized into an inhalation aerosol by targeting the UV cannabinoid absorption peak between 209-222 nm. For example, A9-THC, A9-THCA, CBD, and CBDA have a maximum absorbance at 210.50 nm, 221.24 nm, 209.09 nm, and 221.51 nm, respectively. Thus, infrared emission targeting THC and CBC in the near IR with a range of 1600 nm to 2400 nm with, for example, a peak at 2000nm and far IR of 5,500 nm to 8,500 nm may be used. In an embodiment, the far IR emission may also serve to mobilize terpenes, if present, in the precursor mixture.

[0038] Reservoir 130 may be manufactured from materials that are inert, non-reactive, thermally stable, and non-contributory to any reaction with an intake gas, precursor or formed aerosol. In some examples, it may be desirable to manufacture reservoir 130 from materials having some ability to transmit infrared radiation such as quartz. In an embodiment, reservoir 130 is made from quartz to allow IR and UV light transmission from heater 140 to the precursor composition. In an embodiment, reaction chamber 120 may be made from borosilicate to prevent UV light from heater 140 from escaping reaction chamber 120 and/or vaporizing device 100.

[0039] Heater 140 may be configured to deliver thermal energy to a precursor composition within reservoir 130. Heater 140 may employ various heating mechanisms such as resistive heating, induction heating, infrared heating, or carbon-resistive heating, to provide the required thermal energy. In an embodiment, heater 140 may be a glass encapsulated, gas-filled, sealed vessel with a filament, resistant element, or diode encased therein and two or more points to establish electrical contact with said filament, resistant element, or diode. In some instances, the filament, resistant element or diode may emit non- visible infrared light and/or ultraviolet light. Alternatively, heater 140 may emit visible light. The output of heater 140 may be adjusted by control system 150 to facilitate a desired reaction.

[0040] Control system 150 may be configured to receive user inputs and manage the operation of heater 140. It may include various systems and circuitry configured to measure the output of heater 140 and adjust energy supplied to it in order to regulate temperature. For example, control system 150 may employ one or more rotary encoders, potentiometers, push buttons, keypads and the like to receive user inputs, such as the desired on-time and temperature settings for heater 140. A user operated push-button may be used to activate heater 140. To measure heat output of heater 140, control system 150 may utilize a temperature sensor. For example, thermocouples, resistance temperature detectors, thermistors, non-contact temperature sensors, semiconductor-based temperature sensors or other suitable components may be used to measure heat output of heater 140. Control system 150 may utilize various means for controlling the output of heater 140. Some examples of controlling heater 140 include: pulse width modulation (PWM), On/Off (Bang-Bang) control, voltage control, current control, time proportional control (TP I), and proportional-integral- derivative (PID). Control system 150 may incorporate LEDs or other indicators to visually convey information to the user, such as temperature, on-time, or battery charge.

[0041] Vaporizing device 100 may include intake gas particle size selection system 162 and aerosol particle size selection system 164, which condition both an intake gas stream and an aerosol gas stream. These systems may comprise a series of impaction surfaces and flow regions, designed with specific geometry and architecture to adjust the velocity, pressure, and direction of flow for both an intake gas and aerosol. For example, regions of constriction may increase the velocity of the intake gas or aerosol, while regions of expansion may decrease their velocity. Increasing the velocity may help keep particles in suspension, reduce settling, and encourage the breakup of larger droplets into smaller ones due to shear forces. Increasing the pressure may increase the particle density, potentially leading to condensation (especially for water vapor), particle aggregation, and changes in flow patterns. Conversely, decreasing the velocity could result in particle settling and reduced suspension, while decreasing the pressure may limit condensation and reduce particle density in the gas. Impacting the stream against a wall may cause particles to condense or fall out of the stream. These various mechanisms, such as flow control and impaction, help remove larger particles or contaminants, ensuring that the aerosol delivered to the user is of the optimal particle size for inhalation.

[0042] Intake gas particle size selection system 162 may comprise an input coupled to filtration and scrubbing unit 110 and an output coupled to reaction chamber 120. Aerosol particle size selection system 164 may comprise an input coupled to reaction chamber 120 and an output coupled to condenser 170.

[0043] Intake gas particle size selection system 162 and aerosol particle size selection system 164 may be manufactured from materials that are inert, non-reactive, thermally stable, and non-contributory to any reaction with an intake gas, precursor or formed aerosol. For example, borosilicate or quartz may be used to manufacture intake gas particle size selection system 162 and aerosol particle size selection system 164.

[0044] Condenser 170 may function as a heat exchanger, in fluid communication with a liquid medium in filtration and scrubbing unit 110, and may be configured to further condition an aerosol after it exits reaction chamber 120 and passes through aerosol particle size selection system 164. In one embodiment, condenser 170 may comprise a coiled tube structure that maximizes the surface area in thermal communication with a liquid reservoir, facilitating efficient thermal exchange. This design may increase the surface area for heat transfer compared to a standard tube, enhancing condenser’s 170 efficiency. Examples of suitable condensers for this purpose include: Liebig, Allihn, Graham, Dimroth, and Friedrichs condensers. Condenser 170 may help to regulate the temperature and humidity of an aerosol to appropriate levels for safe and effective inhalation. The fluid dynamics within condenser 170 enable the necessary thermal exchange, ensuring the aerosol is delivered with the correct temperature and moisture content. In some embodiments, condenser 170 may have a consistent inner diameter to promote laminar flow, which reduces the impaction of aerosol particles against the walls of condenser 170. As the aerosol flows through condenser 170, the temperature of the tubing seeks thermal equilibrium with a liquid flowing along the outer wall. The aerosol flow also seeks thermal equilibrium with the inner wall of condenser 170, either cooling the aerosol relative to its initial temperature or heating it, depending on the specific embodiment.

[0045] Condenser 170 may be manufactured from materials that are inert, non- reactive, thermally stable, and non-contributory to any reaction with an intake gas, precursor or formed aerosol. For example, borosilicate or quartz may be used to manufacture Condenser 170.

[0046] Mouthpiece 180 may be configured to deliver an aerosol to a user. Mouthpiece 180 may comprise a tubular body with one end coupled to condenser 170 and the other configured to comfortably interface with a user’s lips. In some embodiments, mouthpiece 180 may be adjustable, allowing the user to position it as needed. For instance, a ball-and-socket joint could enable the user to easily adjust the angle or orientation of mouthpiece 180. Mouthpiece 180 may be made from materials that are inert, non-reactive, thermally stable, and do not contribute to any reactions with the intake gas, precursor, or formed aerosol. Examples of suitable materials for manufacturing mouthpiece 180 include borosilicate glass or quartz.

[0047] Figure 2 illustrates a block diagram of vaporizing device 200, which may be an example of vaporizing device 100. In operation, user 290 applies suction to mouthpiece 280, causing an intake gas to flow into filtration and scrubbing unit 210. Filtration and scrubbing unit 210 may include an intake tube with a first end positioned outside the primary body of filtration and scrubbing unit 210, and a second end located within the unit. This arrangement allows the intake gas to be delivered to liquid contained in filtration and scrubbing unit 210. The first end of the intake tube may feature an adjustable flow port or valve to enable user 290 to control the intake gas flow. In some examples, the second end may include one or more ports designed to direct the intake gas beneath the liquid surface, encouraging a turbulent, non-linear flow. Some embodiments may have two ports positioned 180 degrees apart and perpendicular to the intake gas flow. In other examples, the second end may deliver intake gas above the surface of a liquid and filtration and scrubbing unit 210 may include internal geometry to direct the intake gas to flow through the liquid.

[0048] Forcing intake gas through a liquid may help to scrub or filter the intake gas by removing particles, and in some embodiments, by bringing elements in the intake gas stream into solvation. This filtration process reduces particle contamination in the intake gas by passing it through a liquid medium, which may also help normalize the gas's temperature and humidity. To normalize the temperature and humidity of the intake gas, the flow path may be designed to maximize the distance traveled by the intake gas through the liquid.

[0049] Filtration and scrubbing unit 210 may be configured to enhance turbulent flow, increasing the transit time of the intake gas in the liquid, thereby allowing more time for the intake gas to equilibrate with the liquid. In some embodiments, condenser 270 may be housed within filtration and scrubbing unit 210, either partially or fully submerged in the liquid and may generate flow disturbances that further increase turbulence. Condenser 270 may interact with the intake gas flow to induce additional turbulence and can also heat or cool the liquid. This, in turn, may alter the temperature of the intake gas. Heating the intake gas may facilitate thermally mediated reactions in reaction chamber 220, providing the necessary thermal energy for various reactions, phase changes, or other thermally influenced processes. The humidity of the intake gas is normalized as it passes through the liquid medium and the boundary layer at a liquid-air interface within filtration and scrubbing unit 210. In some embodiments, the liquid may include a humectant, such as vegetable-based glycerol, to adjust the humidity of the intake gas.

[0050] Percolation of intake gas through a liquid can play a significant role in disrupting a thermal boundary layer that forms at the interface between the liquid and condenser 270, thereby enhancing heat transfer. As intake gas percolates through the liquid, it forms bubbles that rise to the surface. Upon reaching the liquid surface, these bubbles may burst, causing localized splashing that results in droplets of liquid being ejected and dispersed onto areas of condenser 270 that are not fully immersed in the liquid. The ejected liquid droplets may accumulate on condenser’s 270 surface and, over time, flow over the surface, eventually dripping down the body of condenser 270. This process of dripping liquid, combined with the enhanced surface contact between the droplets and condenser 270, facilitates improved heat transfer. Furthermore, the interaction between the droplets and the surface of condenser 270 may help to prevent the formation or accumulation of a thermal boundary layer within the liquid. By minimizing the presence of this insulating layer, the overall heat transfer efficiency may be substantially improved, ensuring more effective cooling or heat exchange between the liquid and condenser 270.

[0051] Vaporizing device 200 may include intake gas particle size selection system 262, coupled to the outlet of filtration and scrubbing unit 210. As the intake gas stream flows through intake gas particle size selection system 262, it passes through regions of constriction, expansion, and directional changes, transitioning between laminar and turbulent flow. This may result in variations in velocity, pressure, direction, and flow states and can cause certain particles to drop out of the gas stream due to gravity, while others may break down into smaller particles. In particular, water particles within a gas stream may undergo condensation or coalescence as the flow velocity decreases and the pressure increases in certain regions. When the flow transitions from a higher velocity state to a slower, more laminar state, water vapor or droplets may condense into liquid, contributing to the normalization of the stream. Some embodiments of intake gas particle size selection system 262 may include filters, such as glass frits, along the flow path to further capture or filter out water and particulate matter and encourage turbulent flow.

[0052] A stream of intake gas may flow from intake gas particle size selection system 262 into reaction chamber 220. Reaction chamber 220 may include geometry or architecture to direct the stream to flow in the vicinity of reservoir 230. In some embodiments, reaction chamber 220 may include internal geometry configured to force the stream of intake gas to travel in a vortical or helical path in the vicinity of reservoir 230. Control system 250 may supply electrical energy to heater 240 to heat a precursor composition to a predetermined temperature. Control system 250 may allow user 290 to set a desired temperature and on-time for heater 240. When activated, heater 240 may facilitate a thermally mediated reaction and constituents within a precursor composition may interact with a stream of conditioned intake gas to form an aerosol. Suction provided by user 290 may draw the aerosol out of reaction chamber 220. In some embodiments, reaction chamber 220 may include a variable port or aperture to allow user 290 to control an exit flow of aerosol from reaction chamber 220.

[0053] Heater 240 may be, or comprise, an infrared (IR) and/or ultraviolet (UV) light emitter. The IR and/or UV light from heater 240 may be absorbed by the precursor composition thereby heating the precursor composition. The precursor composition may be IR and/or UV light absorptive. The precursor composition may be doped and/or formulated to make and/or enhance the IR and/or UV light absorption characteristics of the precursor composition. The UV light may help sterilize the precursor composition and/or the reservoir 230. Thus, in some embodiments, heater 240 may heat the precursor via IR and/or UV radiation without directly heating reservoir 230 and/or reaction chamber 220.

[0054] Reservoir 230 may be manufactured from materials that are inert, non-reactive, thermally stable, and non-contributory to any reaction with an intake gas, precursor or formed aerosol. In some examples, it may be desirable to manufacture reservoir 230 from materials having some ability to transmit infrared radiation such as quartz. In an embodiment, reservoir 230 is made from quartz to allow IR and UV light transmission from heater 240 to the precursor composition. In an embodiment, reaction chamber 220 may be made from borosilicate to prevent UV light from heater 240 from escaping reaction chamber 220 and/or vaporizing device 200. In an embodiment, reaction chamber 220 may be made from borosilicate to prevent user 290 from being exposed to UV light from heater 240.

[0055] Reaction chamber 220 may be coupled to a first end of aerosol particle size selection system 264. Aerosol particle size selection system 264 may comprise regions of constriction, expansion, and changes in direction, transitioning between laminar and turbulent flow similar to intake gas particle size selection system 262 to selectively remove particles from the aerosol stream. A second end of aerosol particle size selection system 264 may be coupled to condenser 270.

[0056] Condenser 270 may be positioned within filtration and scrubbing unit 210, in contact with the liquid inside the unit. The stream of intake gas, generated by user’s 290 suction, displaces the liquid around condenser 270. The movement of liquid over condenser 270 serves to thermally regulate it, either cooling or heating it based on the surrounding liquid's temperature. The flow of liquid around condenser 270 depends on the intake gas's volume and velocity, which, in some embodiments, can be controlled by the intake orifice size and the architecture of the intake ports, as well as the suction applied by user 290. In some embodiments, the liquid may serve to cool, heat, or maintain condenser 270 at a set temperature, such as ambient or physiological temperature (99°F).

[0057] The aerosol stream may enter condenser 270 which, in some embodiments, may have a consistent inner diameter allowing for laminar flow reducing undesired impaction of aerosol particles with the condenser 270 wall. The aerosol flow may pass through condenser 270 and the temperature of condenser 270 seeks thermal equilibrium with the liquid volume and dynamic flow occurring on the outer wall of condenser 270, the aerosol flow also seeks to be in thermal equilibrium with the inner wall of condenser 270 flow path and is thermally mediated, for example cooled relative to the aerosol temperature when compared to the liquid temperature or heated when the same comparison is made depending on the embodiment.

[0058] Vaporizing device 200 may include mouthpiece 280 coupled to condenser 270. Suction applied to mouthpiece 280 by user 290 may cause an aerosol to flow from condenser 270 and out through mouthpiece 280. In some embodiments, user 290 may position mouthpiece 280 in a comfortable position.

[0059] Figures 3 A - 3C are exploded views of a vaporizing device. Figures 3D - 3F are isometric views of a vaporizing device as viewed from an angle designated by arrow 301. Vaporizing device 300 may be an example of vaporizing device 100 and vaporizing device 200. Figure 3A illustrates two primary subassemblies of vaporizing device 300: condenser reactor subassembly 302 and control system subassembly 350. Condenser reactor subassembly 302 may comprise filtration and scrubbing unit 310, reaction chamber 320, and portions of intake particle size selection system 362 and aerosol particle size selection system 364. Filtration and scrubbing unit 310 and reaction chamber 320 may be separated from body 363, lid 361, and bottom 365 of intake particle size selection system 362 as illustrated in Figure 3B. Condenser reactor subassembly 302 may be further separated into filtration and scrubbing unit 310 and reaction chamber 320 as illustrated in Figure 3C. Control system subassembly 350 comprises heater 340, user interface 352, and power source 354. Vaporizing device 300 may comprise a modular construction possibly allowing for customizability, upgradability, easier repairs, and maintenance.

[0060] As illustrated in Figures 3 A and 3B, filtration and scrubbing unit 310 and reaction chamber 320 may be partially contained in intake particle size selection system 362. Intake particle size selection system 362 may include a housing comprising lid 361, body 363, and bottom 365. Lid 361 may comprise a split assembly configured to aid in the assembly of vaporizing device 300. In this example, lid 361 forms a shallow cylinder having through holes allowing lid 361 to clamp around filtration and scrubbing unit 310 and reaction chamber 320 with a flange at the top configured to mate with ring 366. Ring 366 may be used to hold the two halves of lid 361 together. In this example, body 363 is primarily cylindrical and may include threads configured to mate with threads included on lid 361. In this case, lid 361 might be clamped around filtration and scrubbing unit 310 and reaction chamber 320, secured by ring 366 and then threaded onto body 363. If body 363 comprised a cuboid, rather than a cylindrical, shape a flange may be used in lieu of threads to allow lid 361 to clamp to body 363. Bottom 365 may be assembled to body 363 using threads, friction fit, or some other suitable means of assembly. O-rings 304 may help to seal intake particle size selection system 362. Once assembled, lid 361, body 363, and bottom 365 form an enclosed expansion chamber for an intake gas to travel between first tube 368 and second tube 369.

[0061] In this example, the body of filtration and scrubbing unit 310 may comprise a capsule, or pill, shape configured to contain a condenser (not shown), such as condenser 170, 270 nested inside of another capsule shaped body. However, it should be understood that the shape of filtration and scrubbing unit 310 could be changed to suit manufacturing, assembly, or other concerns. For example, body of filtration and scrubbing unit 310 may comprise a cuboid rather than a cylinder. A condenser, such as condenser 170, 270 may be fused, welded, or otherwise joined to filtration and scrubbing unit 310 to form a single part. Nesting multiple bodies together may create interior geometry to contain a liquid and direct a flow of intake gas through the liquid. In this example, a lower portion (socket) of a ball and socket joint comprising mouthpiece 380 is integral to the top of filtration and scrubbing unit 310 and fluidically connected to a condenser contained within. The outer wall of filtration and scrubbing unit 310 may have ports to couple to intake tube 314, first tube 368 of intake gas particle selection system 362, second tube 311 of aerosol particle size selection system 364, and mouthpiece 380. These ports may be coupled or joined to other elements comprising vaporizing device 300. For example, intake tube 314 could be fused to the body of filtration and scrubbing unit 310 if those parts were manufacture from glass.

[0062] Filtration and scrubbing unit 310 may include intake tube 314 having a first end to draw air from the exterior of vaporizing device 300 and a second end to deliver air to the interior of filtration and scrubbing unit 310. Intake tube 314 may be fused to the body of filtration and scrubbing unit 310 to form a single part. The first end of intake tube 314 may be configured to mate with valve 312. Tapered joints, threaded joints, O-ring seals, flange joints, or clamps and clips may be used to couple valve 312 to intake tube 314. The second end may deliver intake gas to the interior of filtration and scrubbing unit 310 between a first wall and a second wall.

[0063] Reaction chamber 320 may comprise a volume configured to mix constituents generated from a thermally mediated reaction of a precursor with an intake gas to generate and aerosol. In this example, the body of reaction chamber 320 is primarily cylindrical, however other shapes may suffice. Reaction chamber 320 includes an opening at the top to allow a user to deposit a precursor into a reservoir (not shown), such as reservoir 130, 230, contained within reaction chamber 320. This opening may be configured to mate with cap 322. Tapered joints, flanges, threads, or other means of coupling two parts may be used to mate cap 322 to reaction chamber 320. In some embodiments, cap 322 may include one or more ports configured to interact with one or more ports included in reaction chamber 320 forming an adjustable port when assembled to allow a user to control a flow of aerosol by rotating cap 322 in relation to reaction chamber 320. Reaction chamber 320 may include ports for receiving intake gas from intake gas particle size selection system 362 and delivering an aerosol to aerosol particle size selection system 364. The body of reaction chamber 320 may be configured to partially encase heater 340 to prevent intake gas, precursor, aerosol, or liquid from coming into contact with heater 340. [0064] Heater 340 may be, or comprise, an infrared (IR) and/or ultraviolet (UV) light emitter. The IR and/or UV light from heater 340 may be absorbed by the precursor composition thereby heating the precursor composition. The precursor composition may be IR and/or UV light absorptive. The precursor composition may be doped and/or formulated to make and/or enhance the IR and/or UV light absorption characteristics of the precursor composition. The UV light may help sterilize the precursor composition and/or the reservoir 330. Thus, in some embodiments, heater 340 may heat the precursor via IR and/or UV radiation without directly heating reservoir 330 and/or reaction chamber 320.

[0065] Reservoir 330 may be manufactured from materials that are inert, non-reactive, thermally stable, and non-contributory to any reaction with an intake gas, precursor or formed aerosol. In some examples, it may be desirable to manufacture reservoir 330 from materials having some ability to transmit infrared radiation such as quartz. In an embodiment, reservoir 330 is made from quartz to allow IR and UV light transmission from heater 340 to the precursor composition. In an embodiment, reaction chamber 320 may be made from borosilicate to prevent UV light from heater 340 from escaping reaction chamber 320 and/or vaporizing device 300. In an embodiment, reaction chamber 220 may be made from borosilicate to prevent a user from being exposed to UV light from heater 340.

[0066] In this example, various elements comprising intake gas particle size selection system 362 and aerosol particle size selection system 364 have been integrated into other components of vaporizing device 300 such as filtration and scrubbing unit 310 and reaction chamber 320.

[0067] Intake gas particle size selection system 362 may comprise lid 361, body 363, bottom 365, ring 366, filters 367, first tube 368, and second tube 369. First tube 368 may comprise a first end and a second end. The first end may be configured to receive an intake gas from filtration and scrubbing unit 310 and the second end may be configured to deliver said intake gas into an expansion chamber. In this example, the first end of first tube 368 is joined to the body of filtration and scrubbing unit 310 and the second end includes filter 367. First tube 368 comprises a consistent cross section configured to promote a high-velocity laminar flow of an intake gas with directional changes that may cause heavier particles within a stream of intake gas to impact interior surfaces of first tube 368 before forcing the intake gas through filter 367.

[0068] Lid 361, body 363, bottom 365, and ring 366 combine to form an expansion chamber for intake gas particle size selection system 362. This expansion chamber may create a region of low velocity, high pressure, turbulent flow for an intake gas. The irregular shapes of filtration and scrubbing unit 310 and reaction chamber 320, partially contained within the expansion chamber, may aid to create turbulence. Second tube 369 may comprise a first end and a second end. The first end of second tube 369 may by coupled to filter 367 and configured to receive an intake gas from the expansion chamber. The second end of second tube 369 may be coupled to the body of reaction chamber 320. In this example, second tube 369 comprises a consistent cross section configured to promote a high-velocity laminar flow of an intake gas with directional changes that may cause heavier particles within a stream of intake gas to impact interior surfaces of second tube 369. Additional expansion chambers may be integral to reaction chamber 320. Second tube 369 may feed intake gas into these additional expansion chambers which may be configured to supply intake gas in the vicinity of a reservoir contained within reaction chamber 320.

[0069] Aerosol particle size selection system 364 may be configured to condition a flow of aerosol by exposing the flow to regions of contraction and expansion, turbulent and laminar flow, similar to intake gas particle size selection system 362 to selectively remove particles from the flow. A first region of expansion of aerosol particle size selection system 364 may be a chamber integral to, and surrounding, reaction chamber 320. Aerosol particle size selection system 364 may comprise first tube 321 and second tube 311. First tube 321 may comprise a first end and a second end. The first end may be coupled to reaction chamber 320 and be configured to receive an aerosol from a first expansion chamber. The second end may be configured to couple to second tube 311 and deliver an aerosol. First tube 321 comprises a consistent cross section configured to promote a high-velocity laminar flow of an aerosol with a directional change that may cause heavier particles within a stream of aerosol to impact interior surfaces of second tube 311. Second tube 311 may comprise a first end and a second end. The first end may be configured to couple to the second end of first tube 321 and receive an aerosol. The second end may be joined to the body of filtration and scrubbing unit 310 and a condenser (not shown) contained within filtration and scrubbing unit 310 and be configured to deliver an aerosol to said condenser. Aerosol particle size selection system 364 may be divided into first tube 321 and second tube 311 primarily to aid in manufacturing and assembly. In some embodiments, it may be desirable for aerosol particle size selection system 364 to comprise a single unit.

[0070] Control system subassembly 350 may comprise heater 340, user interface 352, power source 354. The primary body of control system subassembly 350 may house systems and circuitry to receive user inputs, communicate data to a user, and control heater 340. In an embodiment, the primary body of control system subassembly 350 may be manufactured from plastic or other materials. Heater 340 is located such that it may be in close proximity to a reservoir included in reaction chamber 320 when vaporizing device 300 is assembled. User interface 352 may be located at the top of control system subassembly 350 in this example. User interface 352 may comprise a means for receiving user inputs such as: rotary encoders, push buttons, potentiometers, or other means of converting physical movement or positioning into electronic signals. In an embodiment, user interface 352 may comprise a dual concentric encoder and a push button to collect input data. For example, one rotary encoder could be used to set a desired temperature for heater 340 while the other could be used to set a desired on-time for heater 340. A push button could be used to activate heater 340 for a predetermined time at a predetermined temperature when depressed by a user.

[0071] Power source 354 may comprise a battery or cable to interface with power outlet. Power source 354 is illustrated as a detachable battery pack in this example but control system subassembly 350 could include a USB port or the like to connect to a power outlet in a house or building when power source 354 is disconnected. Power source 354 may include one or more rechargeable batteries and circuity to properly charge said batteries. Power source 354 may include a port, such as a USB port, to charge batteries. Power source 354 may include a means to couple it to vaporizing device 300 such as clamps, magnets, clips, latches or other means to mechanically couple two items together. Control system subassembly 350 and power source 354 could use detachable connectors such as pogo pins to transfer power from power source 354 to control system subassembly 350.

[0072] Figure 4A is an exploded view, and Figure 4B is a cross-section view of filtration and scrubbing unit 410. Filtration and scrubbing unit 410 may be an example of filtration and scrubbing unit 110, 210, and 310. Filtration and scrubbing unit 410 may comprise outer wall 402, which may include a port that is coupled to intake tube 404 to receive intake gas 491. Outer wall 402 may form a housing configured to contain liquid 494 and condenser 470, which may be housed within inner wall 403. Liquid 494 may be introduced into filtration and scrubbing unit 410 via intake tube 404 and filled to a level below where intake gas particle size selection tube 406 interfaces with inner wall 403. The space between outer wall 402 and inner wall 403 forms a cavity that may force intake gas 491 through liquid 494. Inner wall 403 includes aperture 409 at the bottom. When a vacuum is applied to intake gas particle size selection tube 406, intake gas 491 is drawn through valve 412 and intake tube 404, flowing through liquid 491 contained in the cavity between the walls, and entering near condenser 470 through aperture 409. Intake gas 491 then travels around condenser 470 creating a dynamic mixture of intake gas 491 and liquid 494 around condenser 470 before exiting at intake gas particle size selection tube 406.

[0073] Intake gas particle size selection tube 406 may pass through outer wall 402, though intake gas particle size selection tube 406 and be joined to outer wall 402 to seal the unit. One end of intake gas particle size selection tube 406 is disposed on the interior of a cavity formed by inner wall 403 and configured to receive a flow of intake gas 491. Intake gas 491 will travel to reaction chamber 420 where it may combine with constituents released from precursor 431 to form aerosol 493. Aerosol 493 will be directed to flow into aerosol particle size selection tube 411 and then be delivered to one end of condenser 470.

[0074] Aerosol particle size selection tube 411 may be joined to outer wall 402, inner wall 403 and condenser 470 in some examples. Aerosol particle size selection tube 411 is configured to deliver aerosol 493 to condenser 470.

[0075] In this example, condenser 470 is formed as a coiled tube, although other shapes and types of condensers or heat exchangers may be utilized. Condenser 470 has a first end connected to aerosol particle size selection tube 411 to receive aerosol 493, and a second end connected to mouthpiece 480 to deliver aerosol 493 to a user.

[0076] Mouthpiece 480 may comprise tip 481, ball 482, and socket 483. In this example, socket 483 is joined to inner wall 403. In addition, socket 483 is in fluid communication with condenser 470 and configured to receive aerosol 493 from condenser 470. Socket 483 is configured to mate with ball 482 to allow tip 481 to be positioned by a user for comfortable use. Ball 482 includes an interior passage to allow aerosol 493 to flow through to tip 481. Tip 481 may couple to ball 482 using a tapered joint. Threaded, friction fit, or other methods of joinery may also be used to couple tip 481 to ball 482. Tip includes an interior passageway to deliver aerosol 493 to a user.

[0077] Figure 4B is a cross-section illustrating the operation of filtration and scrubbing unit 410, a portion of an intake gas particle size selection system and aerosol particle size selection system, and condenser 470 for a vaporizing device. In operation, an external source of suction creates a flow of intake gas 491 and aerosol 493 through the device. Intake gas 491 begins by flowing through valve 412. Valve 412 may comprise button 413, spring 414, valve body 415, and adjustment screw 416. Spring 414 holds valve 412 closed and allows a user to open valve 412 by pressing button 413. Intake gas 491 may pass through valve 412 when it is closed depending upon how it is adjusted. The interface where the head of adjustment screw 416 meets the bottom of valve body 415 creates an adjustable port. The size of the port may be adjusted by threading adjustment screw 416 in or out. Threading adjustment screw 416 in may decrease the size of the port and threading adjustment screw 416 out may increase the size of the port for both open and closed positions of valve 412. Depressing button 413 may open valve 412 to allow more intake gas 491 to flow into filtration and scrubbing unit 410. [0078] Intake gas 491 is encouraged to maintain laminar flow through consistent inner diameter of intake tube 404 before entering a chamber and encountering a directional change created by outer wall 402 and inner wall 403. Suction draws intake gas 491 into a column of liquid 494 and through aperture 409 located at the bottom of inner wall 403. Condenser 470 is contained within a chamber created by inner wall 403. Condenser 470 partially obstructs the flow of intake gas 491 through liquid 494 creating a dynamic and turbulent flow path. This helps to move liquid 494 around condenser 470 to normalize a temperature difference between condenser 470 and liquid 494 and may increase transit time of intake gas 491 through liquid 494 to promote conditioning of intake gas 491. Conditioning of intake gas 491 may involve normalizing the temperature of intake gas with liquid 494 and condenser 470 and humidification of intake gas 491. Eventually intake gas 491 exits a boundary layer of liquid 494.

[0079] Percolation of intake gas 491 through liquid 494 can play a significant role in disrupting a thermal boundary layer that forms at the interface between liquid 494 and condenser 470, thereby enhancing heat transfer. As intake gas 491 percolates through liquid 494, it forms bubbles that rise to the surface. Upon reaching liquid 494 surface, these bubbles may burst, causing localized splashing that results in droplets of liquid 494 being ejected and dispersed onto areas of condenser 470 that are not fully immersed in liquid 494. The ejected liquid 494 droplets may accumulate on condenser’s 470 surface and, over time, flow over the surface, eventually dripping down the body of condenser 470. This process of dripping liquid 494, combined with the enhanced surface contact between the droplets and condenser 470, facilitates improved heat transfer. Furthermore, the interaction between the droplets and the surface of condenser 470 may help to prevent the formation or accumulation of a thermal boundary layer within liquid 494. By minimizing the presence of this insulating layer, the overall heat transfer efficiency may be substantially improved, ensuring more effective cooling or heat exchange between liquid 494 and condenser 470.

[0080] Intake gas 491 will be conditioned intake gas 492 after exiting a boundary layer of liquid 494. A volume of space defined by the surface of liquid 494 and inner wall 403 exists within filtration and scrubbing unit 400. This space may be considered a first region of expansion for an intake gas particle size selection system such as intake gas particle size selection system 162, 262, and 362. This region may be characterized by a high pressure, low velocity, turbulent flow of conditioned intake gas 492. Conditioned intake gas 492 will travel from this first region into intake gas particle size selection tube 406. Intake gas particle size selection tube 406 may have a consistent inner diameter promoting low pressure, high velocity, laminar flow of conditioned intake gas 492. Intake gas particle size selection tube 406 may include multiple directional changes potentially causing heavier particles included in the flow of conditioned intake gas 492 to impact an inner wall of intake gas particle size selection tube 406. Impaction of heavy particles against a wall may cause particles to condense out of the flow or break the particles into smaller particles. Conditioned intake gas 492 exits intake gas particle size selection tube 406 at filter 408 before entering a second region of expansion. Filter 408 may comprise a porous mass, such as a glass frit. Filter 408 may block the passage of solid particles included in a stream of conditioned intake gas 492 and may cause heavier liquid particles to break up or condense.

[0081] Conditioned intake gas 492 may enter a second region of expansion after exiting intake gas particle size selection tube 406 at filter 408. Though not illustrated in Figure 4B, this second region of expansion may be an example of a region similarly defined by body 363, lid 361, and bottom 365 previously discussed. This second region may be characterized by a high pressure, low velocity, turbulent flow of conditioned intake gas 492. [0082] Conditioned intake gas 492 may then pass through filter 467 to enter second tube 469. Second tube 469 may comprise a consistent inner diameter to promote high velocity, low pressure, laminar flow of conditioned intake gas 492. Second tube 469 may include one or more directional changes potentially causing heavier particles included in the flow of conditioned intake gas 492 to impact an inner wall of second tube 469. Conditioned intake gas 492 may enter a third region of expansion defined by heater column 426 and outer wall 428. As the flow of conditioned intake gas 492 moves upward it encounters impaction surface 433 at the bottom of reservoir body 432. Impaction surface 433 is oriented normal to the flow of conditioned intake gas 492 and may create vortical flow events or eddies.

[0083] A region of constriction is formed at the bottom of reservoir body 432 and outer wall 428. Conditioned intake gas 492 may experience an increase in velocity and a drop in pressure as it transits through this constriction into a final region of expansion before entering reaction chamber 420. Conditioned intake gas 492 may experience additional vortical flow events near the top of this final region of expansion. Above this expansion region exists a region of consistent cross-section created by reservoir body 432 and outer wall 428 promoting high velocity, low pressure, laminar flow. [0084] Conditioned intake gas 492 enters reaction chamber 420 from above. Reservoir 430 holds precursor 431 just above heater 440. Reservoir 430 may be accessible by removing cap 422. Reservoir 430 may be manufactured from quartz or other materials capable of transmitting infrared radiation supplied by heater 440. In this example, the bottom of reservoir 430 includes a dome shape to help increase a surface area of precursor 431 exposed to heater 440. Heater 440 heats precursor 431 to a predetermined temperature for a predetermined amount of time selectively releasing constituents to mix and interact with conditioned intake gas 492 to form aerosol 493.

[0085] Heater 440 may be, or comprise, an infrared (IR) and/or ultraviolet (UV) light emitter. The IR and/or UV light from heater 440 may be absorbed by precursor 431 thereby heating precursor 431. Precursor 431 may be IR and/or UV light absorptive. Precursor 431 may be doped and/or formulated to make and/or enhance the IR and/or UV light absorption characteristics of precursor 431. The UV light may help sterilize precursor 431 and/or reservoir 430. Thus, in some embodiments, heater 440 may heat the precursor via IR and/or UV radiation without directly heating reservoir 430 and/or reaction chamber 420.

[0086] Reservoir 430 may be manufactured from materials that are inert, non-reactive, thermally stable, and non-contributory to any reaction with an intake gas, precursor or formed aerosol. In some examples, it may be desirable to manufacture reservoir 430 from materials having some ability to transmit infrared radiation such as quartz. In an embodiment, reservoir 430 is made from quartz to allow IR and UV light transmission from heater 440 to precursor 431. In an embodiment, reaction chamber 420 may be made from borosilicate to prevent UV light from heater 440 from escaping reaction chamber 420 and/or vaporizing device 400. In an embodiment, reaction chamber 420 may be made from borosilicate to prevent a user from being exposed to UV light from heater 440.

[0087] Aerosol 493 is drawn into a port at the bottom of aerosol flow control 423. Aerosol flow control 423 may include inner ports 424 configured to interact with outer ports 425 of reaction chamber 420 to form user adjustable ports. Aerosol flow control 423 may be rotated in relation to reaction chamber 420 to adjust port size.

[0088] Aerosol 493 flows through inner port 424 and outer port 425 into a first region of expansion of an aerosol particle size selection system. This region is characterized by a low velocity, high pressure, turbulent flow.

[0089] Aerosol 493 enters aerosol particle size selection tube 421, which may comprise a consistent inner diameter to facilitate high velocity, low pressure, laminar flow and one or more directional changes. Aerosol particle size selection tube 421 may be configured to couple to and transfer aerosol 493 to aerosol particle size selection tube 411. [0090] Aerosol particle size selection tube 411 may be configured to deliver aerosol

493 to condenser 470. Aerosol particle size selection tube 411 may also be coupled to outer wall 402 of filtration and scrubbing unit 410. In this embodiment, condenser 470 may be comprised of a coiled tube to maximize surface area of condenser 470 body in thermal communication with liquid 494 and resultant thermal exchange and a consistent inner diameter to promote laminar flow reducing undesired impaction of aerosol 493 particles with condenser 470 wall. Condenser 470 is similar to a Dimroth condenser in this example; however, other types of condensers may be used. The wall of condenser 470 may be in thermal communication with liquid 494. In an embodiment, there may be thermal control of condenser 470 by mobilization of liquid 494 through means of mediated displacement and subsequent dynamic flow (e.g., percolation) secondary to intake gas 491 flow passing through liquid 494. The movement or flow of liquid 494 may serve to thermally regulate condenser 470 as it seeks thermal equilibrium with the mobile liquid 494. A cold liquid 494 moving over condenser 470 may better serve to cool condenser 470 and remove heat from condenser 470 (compared to a static non-moving liquid 494), and similarly, a heated liquid

494 flowing over condenser’s 470 outer surface would better serve to heat condenser 470. The exit flow of aerosol 493 may pass through condenser 470 and the temperature of condenser 470 seeks thermal equilibrium with liquid 494 and dynamic flow occurring on the outer wall of condenser 470, the flow of aerosol 493 also seeks to be in thermal equilibrium with the wall of condenser 470 and is thermally mediated, for example cooled relative to aerosol 493 temperature when compared to liquid 494 temperature or heated when the same comparison is made depending on the embodiment. In an embodiment water is used as liquid 494 to cool condenser 470 and aerosol 493 stream which is warmer comparative to liquid 494.

[0091] Aerosol 493, having undergone thermal mediation by a comparatively long transit in condenser 470, may exit into an expansion region in the center of ball 482 and socket 483. This flow region may be turbulent due to the impact and boundary flow created as the high velocity aerosol 493 exits condenser 470. This turbulence may help prevent the entrainment of larger particles, condensate, or liquid droplets in the aerosol 493 stream. The expansion region also acts as a selection point for particle size, ensuring that only the desired particles, with the correct size and equilibrium saturation, are entrained in the exiting flow of aerosol 493. Finally, aerosol 493 exits through tip 481. [0092] Figures 5A and 5B are block diagrams illustrating a control system for a vaporizing device, such as vaporizing device 100, 200, 300.
