CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to U.S. Provisional Application Serial No. 62/192,432, filed on July 14, 2015, entitled “Exothermal Fluid Vaporizer and Counter Flow Design Exothermal Vaporizer,” and this application also claims priority to U.S. Provisional Application Serial No. 62/269,034, filed on December 18, 2015, entitled “Exothermal Modular Vaporizer,” the contents of each of which are hereby incorporated by reference in their entirety.

Technical Field

The present invention relates to the field of vaporizers, and more particularly to a vaporizer having modular components and a counter-flow design for use with an external heating source.

Background Art

Since the recent introduction of vaporizers, e-cigarettes, and similar devices to the market, "vaping," or inhaling vaporized substances, using such devices has become increasingly popular. However, known vaporizer devices have certain disadvantages, including power supply issues, bulky form factors, and difficulty operating in harsh environmental conditions.

Current devices, such as vaporizers and e-cigarettes, function through electrically heated and controlled vaporization elements. This allows for a very precise level of control, but results in a complete reliance on electricity, batteries, charging devices, and connectors. Despite continuous improvements and developments in battery technology, batteries can only store a fraction of the energy stored in most fuels in terms of volume.

Without the ability to operate independently of electricity, users of current technology devices must carry sufficient stored energy, typically in the form of batteries and a charger to convert line voltage or electricity (such as from a car) into the appropriate voltage and current to recharge the battery contained in the device. The result is a cumbersome experience—not only are the devices themselves large and difficult to operate, but they also often require additional specialized accessories to maintain functionality.

Another significant drawback of the current generation of devices is their susceptibility to failure under harsh environmental conditions. For example, the two conditions that are typically most detrimental to proper operation are humidity and extreme cold. In many cases, water can permanently damage sensitive electronic components in electronic devices. Cold temperatures can significantly impact the battery system's ability to provide the power required for proper vaporization, sometimes rendering the device completely unusable.

Additionally, these known devices cannot be used for smoking (consuming dry matter by burning rather than vaporizing). Additionally, known vaporizer devices may also be difficult to clean and/or customize.

Thus, there are currently no known devices designed for or that provide for accurate and repeatable vaporization of fluids or other materials (e.g., smoking materials) without the use of an integrated heat source and associated control mechanisms. What is needed is a device that allows for easy and consistent vaporization of a substance for inhalation, has a smaller form factor, is easy to clean, and addresses the limitations and other problems faced by current vaporization devices without requiring complex controls, circuitry, and/or integrated energy storage components.

DETAILED DESCRIPTION

The present invention generally relates to vaporizers, and more particularly to a modular vaporizer that is heated to a vaporization temperature of a fluid or active compound, suitable for extracting the fluid or active compound contained in a smoking material by any external heat source of sufficient temperature. Among other features, this new class of vaporizers is distinguished from other types of vaporizers by completely separating the heat source and its associated controls from the vaporization components and material.

In one or more examples of embodiments, the exothermic vaporizer is a novel type of vaporizer that, in various embodiments, is designed to be used with existing fluids intended for use with e-cigarettes and other electronic vaporizers. The exothermic vaporizer does not contain any electronic components. It is also much more compact than currently available electronic devices. In various embodiments, the device can be approximately 3.5 inches long and weigh only approximately 1/4 ounce. However, those skilled in the art will recognize that it can be modified to suit the desired purpose and to suit the desired look and feel. Figures 1 to 3 illustrate various embodiments of an exothermic vaporizer 100. Figure 1 shows the various components of the device. As can be easily seen in Figures 1 to 3, and particularly in Figure 1, the exothermic vaporizer device 100 can be generally divided into three parts: a mouthpiece 102, a body 104 or stem, and a cap 106, which can be a temperature indicating cap. The body 104 contains or has several features, including an air/vapor mixing port 108 , a fluid inlet port 110 , a reservoir 112 , an air inlet 114 , and a wicking material 116 .

As noted, the exothermic vaporizer 100 includes a cap 106 that is removable from the body 104. The cap may be a temperature indicating cap 106. A suitable temperature indicating cap 106 is described in U.S. Patent Application No. 14/142,351, published as U.S. Patent Publication No. 2014/0186015A1, the entire contents of which are hereby incorporated by reference herein in their entirety. The temperature indicating cap 106 is calibrated to indicate or provide a warning that the fluid or smoking material intended for use with the exothermic vaporizer 100 is at an ideal vaporization temperature.

As noted, main body 104 or rod include reservoir 112 or tip. According to one or more examples of an embodiment, reservoir 112 or tip can be hollow so that it can be filled with vaporized fluid or smoking material or include vaporized fluid or smoking material. In various embodiments, reservoir 112 can be constructed of glass or any other substance or material that is applicable to its intended purpose. Fluid/smoking material (not shown) is contained in an internal reservoir, which can be supplied with wicking material 116 or evaporation matrix contained in the end or tip 112 of main body 104 and can be covered by temperature indicating cap 106. In various embodiments, wicking material 116 is made of any suitable heat-resistant wicking material (such as stainless steel or other metal mesh). It is also possible to imagine its modification. Vaporization chamber 158 is formed by the space at the end where main body 104 is covered by cap 106 during operation, and the space also includes wicking material 116 and/or evaporation matrix. The fluid is dripped into the wicking material 116 by capillary action and/or may also be dripped out of the reservoir 112 by pressure fluctuations generated by thermal cycling of the device during and between uses. Due to the heat input required for vaporization, the temperature increase of the device causes the pressure of the air present in the fluid reservoir 112 to increase. This increased pressure can be used to assist in dispensing the fluid from the reservoir 112 and/or dripping into the wicking element. When the device cools, the air in the reservoir 112 contracts and additional air is drawn into the reservoir 112 to replace the dispensed fluid.

As can be seen in Figures 1 to 3, it is apparent that there are three (3) holes or orifices in the body 104. The holes are spaced longitudinally along the length of the body. The first hole or orifice is the main air inlet 114 and is located near the cap 106. The second hole or orifice is the reservoir fill hole 110. The third hole or orifice is the dilution air hole 108 used to adjust the air/steam mix and adjust the performance of the device according to the user's preferences. Although three holes or orifices are specifically described, it is contemplated that more or fewer holes may be used to achieve the purposes provided.

A central tube or condenser 118 is also disposed within the body 104. As can be seen in the accompanying drawings, the condenser has a smaller diameter than the body and provides an airflow gap between the inner surface of the body and the outer surface of the condenser. The condenser tube 118 performs several functions. It serves to form the interior sides of the fluid reservoir 112, acts as a conduit for vapor extraction, and serves as a means of redirecting vapor condensed in the mouthpiece area back to the wicking material 116. The condenser tube 118 can be constructed of any suitable material to withstand heat and perform the functions disclosed herein, such as, but not limited to, glass, stainless steel, or titanium, and combinations thereof.

The mouthpiece 102 is coupled to the body 104 and serves as an interface between the exothermic vaporizer device 100 and the user. The mouthpiece 102 also serves as a valve for the fluid reservoir fill port 110 and the air/steam mixing and/or dilution inlet 108. Specifically, an elastomeric mouthpiece 102 can be provided that is coupled to the body 104 (at its end) and the corresponding port in a tightly sealed fit. This is achieved by means of a suitable slide valve. Although specific examples are provided, it is also conceivable that the mouthpiece 102 or a portion thereof can fit or fit tightly within the end of the body 104. The mouthpiece 102 can be formed of any suitable material, examples of which include, but are not limited to, plastics, rubber materials, glass, metal, wood, etc., and combinations of the foregoing.

The exothermic vaporizer 100 is used to vaporize the fluid contained in the wicking element or material 116 and indirectly from the fluid reservoir 112. Any suitable external heat source (not shown) is used to heat the vaporization chamber (described above) located below or enclosed by the cap 106 to an appropriate temperature. The appropriate temperature is indicated by a calibrated heat-activated element contained within the cap 106.

In one or more instances of using the exothermic vaporizer 100, the user can first load or fill the device with a substance for vaporization and consumption. Next, the user can apply a heat source (such as a lighter) to the base of the device (i.e., the part facing downward when the user holds the vaporizer 100). Then, a metal temperature sensor or a thermal indicator can indicate to the user that the substance is ready for consumption. Next, the user can apply suction to the mouthpiece 102 to consume the substance. This suction produces a pressure drop in the vaporization chamber (as described above), which forces air into the air inlet hole 114, then through or around the evaporation matrix or wicking material 116, and then along the direction of the upward passage through the center tube/condenser 118 to reach the mouthpiece 102, a 180-degree change occurs. When the steam flow enters the mouthpiece area, it is diluted by the dilution air of the air/steam ratio port 108 according to the user's preference. Then, the user can inhale the mixed air and steam. When the temperature in the vaporization chamber drops, the steam output will decrease. After a short while, the temperature indicator may indicate that it has cooled sufficiently and reset, and is now ready for another heating cycle.

One or more alternative examples of embodiments of an exothermic vaporizer 120 having a counter-flow design are shown in FIGs. 4-8 , which illustrate various embodiments of the device. Like the exothermic vaporizer 100 described above, the counter-flow exothermic vaporizer 120 shown in FIGs. 4-8 can be approximately 3.5 inches long and weigh only approximately 1/4 ounce in various embodiments. However, variations thereof do not depart from the overall scope of the present invention.

The various elements of the exothermic vaporizer 120 shown in Figures 4 to 8 are substantially similar to those shown and described in Figures 1 to 3, and therefore, the same reference numerals will be used to identify like parts. The exothermic vaporizer 120 shown in Figures 4 to 8 includes several additional elements. First, one or more vents 122 are positioned near the suction nozzle 102. Next, the internal condenser tube 118 is installed to extend from the suction nozzle 102 through or across the length or approximate length of the device 120, stopping or terminating just short of the diffuser disk 124. The suction nozzle 102 or an O-ring 126 holds the condenser tube 118 in place.

In one or more examples of embodiments, the device may further include a housing or other container or may be mounted within a housing or other container for safety and portability.

The combination of elements of the exothermic vaporizer 120 of Figures 4 through 8 described above includes several features. First, it provides or allows for a tighter fit of the cap 106 relative to the body 104, which improves conductive heat transfer and helps maintain the cap 106 in its proper position during both use and non-use. Second, the majority of the airflow through the device is diverted from the extraction chamber. This provides several benefits, including, but not limited to: extended time at operating temperature; reduced extract concentration; less effort to draw, or minimized suction force when using the device; and reduced extract temperature. Third, as the dilution air entering the device near the mouthpiece 102 travels toward the end of the chamber, carrying any stray vapor with it (where it must then make a 180-degree turn before entering the condenser tube 118), the condenser tube 118 redirects the airflow and cleans the inner surface of the outer tube (i.e., the body 104). This dilution air reduces the accumulation of plant matter and condensation on the inner surface of the outer tube 104. The 180-degree turn of the dilution air flow and the corresponding acceleration of its velocity create a localized drop in air and vapor pressure near the extraction chamber. This promotes the extraction and extraction of the extracted compound from the sample. Next, because the condenser tube 118 has a smaller cross-sectional area and diameter than the main body 104, the dilution air and vaporized extract of the same volume flow rate are now accelerated to a higher speed as it flows through the device. This is combined with the significantly smaller surface area of the condenser tube 118 to minimize the amount of vaporized material condensed out from the air/steam flow. In addition, the incorporation of dilution air reduces the saturation level in the vapor flow, promoting the released compound to remain in the air/steam flow to improve intake and absorption. This process also reduces the temperature of the air/steam flow, which reduces the irritation (harshness or irritation) and/or cough associated with the lung irritation caused by high temperature gases and sprays (such as smoke).

The disclosed improved device also makes cleaning easier. For example, the condenser tube 118 provides an easier way to remove accumulated residue from the device after extended use. In particular, the suction nozzle 102 or the O-ring 126 holds the condenser tube 118 in place, making it easy to remove. Thus, all components are accessible and easy to clean, remove, and/or replace.

9-16 illustrate one or more additional and alternative embodiments of an exothermic vaporizer 130. The various elements of the exothermic vaporizer 130 illustrated in FIG9-16 are substantially similar to those illustrated and described in FIG1-8, and thus, like reference numerals will be used to identify like components. However, the vaporizer 130 illustrated in FIG9-16 includes several additional features, including: a condenser tube 132 comprised of titanium, stainless steel, or other suitable material or combination of materials; a condenser 132 threaded and threaded into a nozzle 136 (having corresponding mating threads) and adjustable to modulate and/or adjust the flow ratio of dilution air to generated vapor; integration of the tip 134 and nozzle 136 into the body 104 using a friction fit O-ring 126 (which, among other things, allows for tool-less assembly and disassembly and thermally isolates the tip 134 from the body 104); a variety of material options for components with standardized interface dimensions; and strategic material usage throughout the device.

Figures 9a through 9c illustrate cross-sections of a modular exothermic vaporizer 130 according to various embodiments. An assembled vaporizer is shown in Figure 10 . With reference to these figures, various components of the exothermic vaporizer 130 are disclosed. The tip 134 of the exothermic modular vaporizer 130 is shown, which couples and/or docks with or is coupled to the condenser tube 132. As noted above, the condenser tube has a smaller diameter than the main body, thereby providing an air gap between the outer surface of the condenser tube and the inner surface of the main body when inserted into the main body. In various embodiments, the condenser tube 132 is optimized for communication with the tip 134 for flow modulation. For example, the tip 134 and/or the condenser 132 may have a tapered portion 135 at the interface for flow modulation. As can be seen in the figures, the tapered portion 135 is a very small/short reduction in the outer diameter of the condenser 132 at the very end or interface surface of the condenser, adjacent to the tip interface surface.

Also shown in Figures 9-10 are heat dissipation features 138, which, in various embodiments, can be in the form of fins that aid in heat dissipation. For example, fins 138 minimize the conduction path by minimizing the cross-sectional area and increasing the surface area over which stray heat conducted away from the vaporizer chamber 158 can be dissipated. Fins 138 or other features can also be used to assist in heat transfer to preheat the incoming vapor exhaust air. This functionality has the added benefit of cooling the end of the tip 134 where it meets the body 104, minimizing heat transfer from the tip 134 to the body 104 in the process of recovering heat conducted away from the vaporizer chamber 158 or lost back into the incoming air flow, which is preheated to further reduce the rate of heat loss from the vaporizer chamber due to the incoming air.

As can be seen with reference to the accompanying drawings and discussed in further detail below, the exothermic vaporizer 130 component can have a groove 140 that is appropriately sized to receive the O-ring 126. The O-ring 126 can be formed from silicone, FKM, Viton ^™ , or other suitable insulating materials (described in further detail below). Additionally, threads 142 can be provided on the condenser tube 132 spaced relative to the tip 134. In various embodiments, this feature allows for a regulated airflow relative to the vapor in the condenser tube 132 of the vaporizer 130.

9c, in one or more optional instances of an embodiment, an arcuate or arched screen or diffuser disk 152 may be provided in the tip 134. The tip 134 may have a plurality of grooves 154 (also shown in FIG9b) for adjusting the size of a vaporization chamber 158 (discussed in further detail below with reference to FIG17-22). In the illustrated embodiment, four (4) such grooves are shown, but one skilled in the art will recognize that more or fewer such grooves 154 may be provided without departing from the overall scope of the present invention. In one or more optional instances of an embodiment, the screen 152 is press-fit into the tip. In this regard, the screen 152 may be provided with circumferential compression and, when combined with its insertion into the grooves, resist the action of forces to retain the screen in the tip.

The foregoing configuration advantageously provides optimal heat management, confinement, and controllable dissipation.

Variable flow rate control may also be provided. For example, the ratio between dilution air flowing directly through the steam chamber and dilution air introduced in the reverse direction may be adjusted by rotating the nozzle 136 relative to the body 104 of the vaporizer 130 (screwing the nozzle 136 in or out), retracting or extending the condenser tube 132 from the nozzle 136, and varying the interface gap between the condenser tube 132 and the tip 134, or otherwise modifying and/or modulating the restriction in the dilution air flow path.

As can be seen with reference to Figures 9a to 9c, the tapered condenser tube 132 (see tapered portion 135) or other flow modulation components are actuated by twisting the nozzle 136 relative to the body 104 to modulate flow control. In various embodiments, this feature is facilitated by engaging the threads 142 provided on the condenser tube 132 with corresponding matching threads 144 incorporated into the nozzle 136 to adjust the condenser tube 132 spaced apart relative to the tip 134. Therefore, the physical action used to facilitate this adjustment is a twisting motion. In other words, the user can twist or untwist the nozzle 136 relative to the body 104, which can then promote the actuation of the condenser tube 132 relative to the nozzle 136, the body 104, and/or the tip 134. Although specific examples are provided, in order to optimize the vapor concentration (flow modulation), other ways of adjusting and/or adjusting the air intake ratio can also be provided, such as sliding and twisting, or other similar methods of engaging one or both sides of the condenser and its matching components. In the depicted embodiment, the condenser tube 132 remains rotationally fixed relative to the body 104 when the nozzle 136 is twisted. Twisting the nozzle 136 causes the condenser tube 132 to rotate in or out, actuating it toward or away from a valve point or restriction. This enables the steam and dilution air mixture to be "dialed in" or modified. In other words, in various embodiments, the condenser tube 132 and/or the tip 134 or the interface hole of the body 104 of the vaporizer 130 are tapered in internal or external dimensions or have a tapered portion 135 to act as a needle valve and valve seat to regulate and modulate the flow rate and adjust the air and steam ratio.

Flow modulation can occur at the internal interface between the condenser tube 132 and the tip 134 (which includes the extraction chamber). Therefore, the tip 134 can have an inner diameter slightly larger than the condenser tube 132. In addition, the tip 134 and/or the condenser tube 132 can have one or more interface surfaces. These interface surfaces can have a tapered portion and a geometric shape that are integrated to increase and/or decrease the orifice disposed therebetween when the tip 134 and the condenser tube 132 extend and/or retract relative to each other. The variable orifice provides a device for adjusting and/or modulating the ratio between the generated steam and/or dilution air. For example, when the user inhales, the steam is discharged from the extraction chamber through the incoming air and is discharged from the condenser tube 132 through the tip 134 (through a diffuser). In addition, in various embodiments, the dilution air can enter the extraction chamber through the space (orifice) provided between the main body 104, the condenser tube 132 and the mouthpiece 136. Additionally or alternatively, an orifice 146 can be provided in the main body 104. While specific examples are described, additional devices that restrict dilution air and/or promote steam generation and/or flow in a user-adjustable manner are also considered within the scope of this disclosure.

In addition to the aforementioned, the variable air/steam ratio that the user can adjust can be used together with liquid vaporizer and other smoking material (such as dry herbs or plant) vaporizer.For example, adjustable variable air/steam ratio can work by similar user-actuated valve regulation and ratio adjustment system.In one embodiment, this feature can be realized by the mouthpiece 136 parts that twist vaporizer 130 relative to main body 104, and this helps condenser to extend and retract to carry out valve regulation modulation with respect to tip 134.This valve regulation can be realized by the threaded portion of inner pipe or condenser tube 132 being screwed into mouthpiece 136, so when mouthpiece 136 rotates relative to condenser tube 132, condenser tube 132 stretches out from mouthpiece 136 or retracts in mouthpiece 136 then.

As noted above, flow modulation can occur at the internal interface between the condenser tube 132 and the tip 134 (which includes the extraction chamber). The tip 134 can have a slightly larger inner diameter than the condenser tube 132, and either the tip 134 or the condenser tube 132, or both, can have a tapered portion incorporated into their respective interface surfaces and dimensions to increase and/or decrease the orifice when extended and/or retracted relative to each other. It is this variable orifice that can result in a described device that adjusts and/or modulates the ratio between the generated steam and/or dilution air.

Can form the additional device of modulation flow by drilling or other orifice, described drilling or other orifice is arranged in straight line (or other suitable) mode from suction nozzle 136 towards steam chamber.When in one embodiment, inner seal or other slidable valve regulating mechanism actuates to be across orifice, this is just the arrangement or pattern of described orifice.When more orifice and the air introduction side isolation of seal or valve regulating mechanism, can modulate and/or limit and introduce air flow.Moveable seal or valve regulating mechanism can be regulated by thread extension/retraction mechanism, and described thread extension/retraction mechanism actuates by relative main body 104 twisting suction nozzle 136.

Another embodiment or means for modulating flow may include a series of grooves 140 on the condenser tube 132 to retain a slidable and repositionable seal (such as an O-ring 126). This arrangement may allow a user to modulate and adjust the device to their preferences for extraction strength and vapor temperature by selecting different seal positions relative to the condenser tube 132 and their positions when retained in the body 104. Although the grooves 140 may be used to retain (one or more) seals, in various embodiments the grooves 140 may not be needed or required. In various embodiments, the means for modulating the desired flow in this arrangement may include the ability to seal or isolate the incoming air flow within any number of orifices in the body 104, which would allow air to enter the interstitial space between the condenser tube 132 and the interior of the body 104, thereby modulating the air flow.

Another embodiment or means for modulating flow may include valving or otherwise restricting an orifice from the outside of the condenser 132. This may be accomplished by a component of the device or a separate device, including the operator's finger.

Another embodiment or device for modulating flow or air/steam regulation can include user-adjustable spring tension against the valve adjustment mechanism. This can allow for real-time operation of a flow and pressure adjustment mechanism that can compensate for air and/or steam flow during use based on the pressure differential generated during use. This feature can allow the user to simply adjust the intensity of the instantaneous extracted steam concentration by increasing and/or decreasing the suction force applied to the mouthpiece 136.

While various examples are specifically provided, alternative or additional means of limiting dilution air and/or promoting steam generation in a user-adjustable manner are also contemplated within the scope of this disclosure.

As shown in Figures 9 to 16, the exothermic vaporizer 130 disclosed herein can be modular. The manner in which the condenser 132, tip 134, and other interface components are connected, actuated, and the corresponding clearances allow for the interchangeability of components and the use of a variety of material types, including materials that would be unsuitable if directly connected without thermal breaks. To facilitate tool-less friction-fit joining of components or parts, it is preferred to maintain close dimensional tolerances to ensure the correct amount of elastic deformation and/or compression required to retain the components with their respective parts.

In Figures 9 to 16, the tip 134, diffuser 124, body 104, and nozzle 136 of a heat releasing modular vaporizer 130 are provided according to various examples of embodiments. A condenser tube 132 is disposed within the body 104 and nozzle 136. As noted above, the condenser tube 132 tapers toward the tip 134 to interact with the tip (and diffuser 124). The tip 134 is detachable from the body 104, and the nozzle 136 is detachable from the condenser 132.

In one or more instances of the embodiment shown in Figure 16, the nozzle or a portion thereof can be a rotating or spinning nozzle 148. For example, the nozzle in one instance of the embodiment is free to rotate 360 degrees. That is, the nozzle or nozzle portion 148 (or conversely the body 104 or a component thereof) can be rotated about the axis 150 so that the body 104 can be rotated relative to the nozzle 148 for uniform heating. In one instance of the embodiment, the nozzle 148 can be coupled to or otherwise attached to the vaporizer 130 by coaxial engagement with the condenser tube 132 passing through the diameter of the nozzle - wherein the nozzle is held in place by an O-ring fixed to the condenser 132 at either end of the nozzle 136. This arrangement provides for retention of the nozzle 148 while also allowing free rotation about the condenser tube 132.

Modularity is aided by the friction fit assembly provided by the O-ring 126 disposed within a groove 140 on the vaporizer 130. In various embodiments, the groove 140 may be disposed on the tip 134, the condenser tube 132, and/or the nozzle 136, however, variations thereof are acceptable to achieve the provided purpose.

In various embodiments, five to eight O-rings 126 may be provided on various portions of the carburetor 130. In one or more specific instances of the embodiment, the O-rings 126 may be coupled together in a certain form (e.g., in the form of a double O-ring) to enhance functionality. However, any number of O-rings 126 or other types of retaining rings may be provided to appropriately achieve the effects disclosed herein. In various embodiments, a recess or groove 140 may also be optionally provided on the device to which the O-ring 126 is secured to allow the O-ring to maintain its position on the device through assembly and disassembly and to provide an appropriate degree of friction fit and/or anti-rotational resistance. The O-ring 126 configuration may allow for quick and easy assembly and disassembly without the need for any tools. This feature may be very desirable to facilitate cleaning residues from some internal surfaces and components.

In various embodiments, an O-ring 126 can be provided on the upper surface of the vaporizer 130 (i.e., near the nozzle) to act as a friction element rather than a seal. For example, an O-ring 126 can be used on the condenser tube 132 to hold the condenser tube 132 in a rotationally fixed position relative to the body 104, while still allowing axial movement. In various embodiments, this feature can act as a higher level of frictional compression fit that resists rotation of the body 104 during "dial-in" or adjustment of the condenser tube 132 relative to the tip 134.

The thickness of the O-ring 126 can be appropriately sized to resist accidental disassembly of the carburetor 130, while still allowing for easy intentional disassembly of the carburetor 130. A suitable example of a friction fit O-ring 126 includes a 6 mm ID x 1 mm cross-section O-ring, although any suitable size combination can be used as long as the O-ring provides the necessary interference fit to retain the components. The O-ring 126 can be composed of any suitable material, an example of which is silicone. Other suitable materials can include Teflon ^™ , Viton ^™ , or any other material that allows for a maximum temperature exceeding 400 degrees Fahrenheit.

In this regard, in addition to providing a friction fit, the O-ring 126 provides an insulating interface between heated and/or hot components and unheated components or components that perform better or are more comfortable when cooled. Thus, the O-ring 126 preferably has a significantly lower thermal conductivity than the components it holds, and separates the components of the vaporizer 130 in the manner described herein. This results in a significantly reduced rate of heat transfer from the "hot end" of the device to cooler areas and/or components. In addition to providing thermal insulation, the O-ring 126 also allows for the joining of materials and/or components having substantially different coefficients of expansion.

Thus, advantages of the selected location, height, and material of the O-ring 126 can include thermal isolation of components of the vaporizer 130. In other words, while normal use of the vaporizer 130 may involve heating the cap 106/tip 134 to a suitably high temperature or degree to vaporize the material provided within the tip 134, the user can continue to grip the body 104 of the vaporizer 130 and consume vapor through the mouthpiece 136 without uncomfortably transferring heat from the tip 134 to the rest of the vaporizer 130. Thermal isolation can be facilitated by the resiliency or space provided by the features of the O-ring 126. In various embodiments, this can eliminate a direct path for conduction and/or heat transfer between the tip 134 and the rest of the vaporizer 130.

In addition, the use of O-rings 126 and grooves 140 to isolate components can allow the use of various materials that may not be compatible with the vaporization device. For example, the entire device can be composed of titanium or other suitable materials. This can include ceramic, stainless steel, or nitinol. In other embodiments, the components can be composed of wood, glass, or any other suitable material. For example, the chamber or body 104 and/or the suction nozzle 136 can be specifically composed of wood or glass, while the tip 134 and/or the suction nozzle 136 can be composed of metal. In another embodiment, the suction nozzle 136 can be composed of wood, the internal condenser tube 132 can be composed of glass, and the tip 134 can be composed of metal (including appropriately conductive materials, including tungsten, gold, titanium, sapphire, etc.). Similarly, one or more components or the entire device 130 can also be formed of plastic, such as by injection molding or other molding techniques. Although specific examples are described, many other suitable combinations and materials can be understood to be included within the scope of this disclosure.

While various examples of embodiments include O-ring couplings of various components of the device, in one or more alternative embodiments, other means may be used to join the components of the exothermic vaporizer 130 disclosed herein. As a non-limiting example, low-temperature couplings may be used to couple materials together while avoiding brazing and other mechanisms that may result in toxic fumes and unwanted metal oxidation or contaminants or residues. Low-temperature couplings may allow the various components of the device to be cooled and assembled in a limited manner to produce a bond nearly as strong as welding. In various embodiments, the device may be fabricated in part by drilling out a bolt so that it fits evenly with the tip 134.

The modular construction and detachable/attachable components of the exothermic vaporizer 130 described herein (including, but not limited to, similarly sized features at component interfaces) allow for the use of a wide range of interchangeable components, providing a simple way to upgrade or simply modify the appearance (and, in some cases, functionality) of the exothermic vaporizer 130 unit according to user preferences. This modularity also allows for the incorporation of aftermarket components to supplement OEM units (e.g., differently shaped components can be used with the disclosed configuration). Modularity also provides the ability to provide the exothermic vaporizer 130 in kit form, comprising one or more of the components described herein, which can be assembled by the user. For example, a kit may include (but is not limited to): one or more bodies, one or more condensers, one or more tips, one or more nozzles, as well as various O-rings and/or other additional components, or fewer components. Each of these components may be made of the same material, or may be formed of different materials as described herein (e.g., a glass body and a titanium body may be provided in a kit, or multiple glass bodies may be provided, etc.). In one or more examples of embodiments, the kit and its components may be provided in one or more containers/packages containing the components.

In addition to the foregoing, in various embodiments a glass filter can be provided for use with the exothermic vaporizer 130. The filter or diffuser disk 124 can be constructed of glass, ceramic, or metal and can be retained in the body 104 by a retaining ring and groove 140, or in another embodiment can be retained in a more permanent manner by heating the glass to create a slight depression in the glass body 104 and allowing the depression to surround the top and bottom of the disk 124.

As noted above, it should be understood that the disclosed device and components of the device can be used for conventional smoking purposes. In other words, the dry material can be placed directly in the device and burned without the use of the cap 106. To this end, a glass or other type of material screen can be provided on the tube to allow direct contact between the heat source and the dry material.

Referring to Figures 17 to 22, a tip 156 is provided for use with a circumferential compression-fit diffuser disc 125 (Figure 22). The illustrated combination enables a user-adjustable vaporizer chamber 158. This is achieved via a groove 154 in the inner wall of the vaporizer chamber 158, into which the circumferential compression-fit diffuser disc 125 can be integrated. To adjust the size, the user can push the circumferential compression-fit diffuser disc 125 all the way to the bottom of the adjustable vaporizer chamber 158, where the groove 160 is deeper, allowing the circumferential compression-fit diffuser disc 125 to be more fully loosened, causing the protrusion to be reversed from insertion. Due to the disc's size, the protrusion will always point in the direction the circumferential compression-fit diffuser disc 125 is being pushed and will resist the corresponding force from the other direction. When the disc is loosened into the deeper groove, the circumferential compression-fit diffuser disc 125 can be reversed and pushed outward from the opposite direction using a tool. The circumferential compression fit diffuser disc 125 will snap into either of the grooves and be held by its own spring pressure resistance through compression of the material from the open end until it is pushed out of the concave side of the ridge for its repositioning or removal.

In addition to the various advantages described above, the exothermic vaporizer described herein addresses several of the shortcomings and dependencies of current electrical devices or many of the shortcomings and dependencies experienced by known vaporizer devices, and provides a seemingly low-tech method for accomplishing the task of vaporizing fluids and other smoking materials without the use of electrical components or any of their associated circuitry or components. Furthermore, the exothermic vaporizer accomplishes one or more of the aforementioned tasks through the use of innovatively designed, precise, and durable non-electronic heat transfer and heat feedback components.

The exothermic vaporizer described herein is designed to operate reliably when heated by nearly any heat source of sufficient intensity. Furthermore, the described vaporizer operates equally well on warm, calm days as on brutally cold, windy days. In the middle of the woods, without any electricity, it can still be reliably and consistently activated with lighter fuel, even a campfire burner.

Furthermore, by utilizing a non-electrical temperature indicator, this device allows for a new level of vaporization, unlike conventional approaches. By separating the heat source and controls from the vaporization device, numerous advantages become apparent. The most significant advantages compared to previously described devices with integrated heat sources are miniaturization and weight reduction. One example of how exothermic vaporizers compare to current integrated devices is the ability to easily hold the device between the user's lips, similar to a cigarette. Without the weight of batteries and the associated controls typically found in electronic devices, this becomes more manageable. Users can now hold the device in their mouth while using it, leaving both hands free for the task.

Likewise, one or more examples of counterflow design exothermic vaporizers and modular exothermic vaporizers are provided, which have various additional advantages, such as: the condenser tube can be titanium or another suitable material; the condenser can be screwed into the mouthpiece and adjustable to modulate and/or adjust the flow ratio of dilution air and generated vapor; the tip and mouthpiece can be integrated into the body via friction fit O-rings - the friction fit O-rings allowing tool-less assembly and disassembly and thermal isolation; and the O-rings can thermally and mechanically isolate the tip from the body, allowing construction using thermally conductive materials without concern for excessive heat conduction and/or uncomfortable surface temperatures affecting the user. Furthermore, the design provides a wide range of material options for different components (such as titanium tip, wood, glass, metal, or ceramic body), as long as the interface points between the components are standardized and consistent. In addition, the reverse introduced airflow path of the device for adjusting and regulating the air/vapor concentration also serves several additional and important functions, such as, but not limited to: the flow path creates a countercurrent heat exchanger whereby, in the process of cooling the air/vapor, the incoming air is output through the walls of the condenser tubes, removing heat and thereby preheating the incoming air, which reduces the temperature difference between the dilution and/or displacement air and the vaporization temperature of the desired compound, thereby maintaining the vaporization temperature in the extraction chamber for a longer time or allowing a larger mass of air and vapor to be heated/produced before falling below a minimum temperature threshold; the coaxial arrangement achieves a significant reduction in size compared to other methods of cooling and/or conditioning the vapor output of the vaporizer; and allows for adjustable chamber size and easily removable and replaceable screens and other accessories for vaporizing fluids and resins - the fluids and resins can be retained using internal and/or external retaining rings and/or O-rings with or without corresponding grooves.

Vaporizers also offer a novel capability: the ability to utilize novel materials in specific areas of the unit where their respective properties are most advantageous, such as the metal extraction tip comprising the chamber and diffuser disk. For example, manufacturing this component from metal or other thermally conductive materials facilitates a more even distribution of heat from the heat source to the target material. In contrast, previous attempts to use thermally conductive materials resulted in the entire device becoming uncomfortably hot, quickly limiting its usefulness. Uniquely, the exothermic vaporizer device, incorporating the various components described herein, allows heating of the substance to be puffed or inhaled, contained within the device, to temperatures exceeding the material's ignition point without promoting combustion. This allows for extended periods of time at operating temperature and allows for a slow decrease in temperature across the entire operating range, thereby maximizing extraction. This advantage is achieved, at least in part, for the other reasons mentioned above, because airflow within the vaporizer is not present until the user inhales.

In addition to the foregoing, the design of the body with dilution air introduction, diffuser disc and a modulation system including a condenser tube for collecting the resin and extractives produced during use means that the device is also used in smoking applications that are substantially better than most dedicated smoking devices. To further elaborate, current smoking devices are generally basic in nature, and the additional features of a device of this design can enhance the smoking experience by providing the user with an additional means of adjusting the strength of the smoke extract and providing a simpler way to separate and retain some of the less desirable heavy tar resins with simple removal and/or cleaning of the condenser tube.

Further, the condenser tube solves one of the more important operational problems of conventional smoking devices that do not have such elements. The problem mentioned is the undesirable accumulation of resin deposits. These deposits are typically a combination of ash and distilled tar and resin with additional hydrocarbons and other incomplete combustion by-products. As these deposits accumulate in conventional devices, they begin to obstruct the air and smoke flow paths, ultimately making the device unusable or difficult to use. The condenser tube utilizes a design that incorporates a reverse introduction of airflow and its corresponding acceleration of the smoke and dilution airflow in the subject matter, as well as a diverging shape after the introduction of dilution air and steam/smoke mixture to reduce the tendency of highly condensable components of the smoke or steam to condense in the restricted portion of the condenser tube. In addition, as in vaporizer use, the condenser tube, which acts as a countercurrent heat exchanger, also helps to cool the generated smoke as it passes through the condenser tube towards the mouthpiece or is discharged.
