The following invention relates to vaporizers which utilize high heat to take solid or liquid materials and convert them at least partially into a gas, such as for inhalation by a user. More particularly, this invention relates to vaporizers which can be attached to a water pipe inlet or to a nebulizer or other equipment designed for inhalation of vapors produced thereby.
Atomization/vaporization of substances is well known for aromatherapy, respiratory therapy, or for smoking activities. While combustion of a solid or liquid substance is one method for production of gas/vapors for inhalation, non-combustion or limited combustion vaporization is also known. This is accomplished though the heating of a selected substance to a temperature at which it undergoes phase change into a gas with no chemical reaction or with different chemical reactions than the basic oxidation/decomposition of hydrocarbon substances into CO2 and water. One known way to so vaporize a substance is to heat a tool until it is of the desired temperature, and then removing it from a heat source before introducing the material which is to be atomized/vaporized. This process allows the material to go though a phase change, called atomization/vaporization instead of being combusted through ignition. Substantial research has established that the atomization/vaporization process is a much healthier, cleaner alternative to combustion.
This invention is intended for any use, limited only by the user's imagination, but its main purpose is for the process of atomization/vaporization of materials. As stated in other patents and shown by the large demand for personal atomizers/vaporizers, there is to date a shortage of well-engineered personal atomizers/vaporizers which are simple to understand and use. Even though there are patents for other devices which accomplish solely vaporization, all of these patents differ in engineering and appearance as well as material and functional properties.
The problem which this invention addresses is the lack of good technology in the industry for simple effective vaporizing/atomizing of essential oils and other solid or liquid substances. All technology to date either employs glass vials which must be screwed into an adaptor and heated up to vaporization temperature, which does not allow continuous use as the users must wait for each to cool down after use before replacing this one used individual glass vial; limiting the efficiency with which the essential oils can be vaporized/atomized.
Another prior art invention relating to this product is a titanium “nail” which is designed to heat up like this product however it requires separate glass adaptors to fit different size water vessels. Such products also require an adaptor, called a “glass dome/oil globe/vapor globe,” which must be removed in order to heat the titanium part and again placed on top of another glass adaptor, with the titanium “nail” in-between, in order to use essential oils.
This prior art titanium “nail” has a flat surface on which the essential oils are placed and vaporized. The vapors must then be directed around the outside of the titanium nail by the glass adaptors and funned down into the correctly sized water vessel.
A need exists for an efficient and revolutionary vaporizer with a self-contained “domeless” function which streamlines and simplifies the process. Users of such a “domeless” device would continue to heat the titanium nail portion and enjoy essential oils without having to remove/replace or unscrew any glass adapters or holders. The user also would enjoy the added ease of not having a “dome” to remove, to heat and then replace.
Other vaporizers use the same type phase change as the atomizer/vaporizer described herein, although other prior art inventions are all limited to vaporizing certain and specific materials. Through exhibiting different processes as well as separate structural engineering, this invention has distinct technology and is able to atomize/vaporize a greater variety of material. Examples of these other devices include:
Though other patents accomplish vaporization, the manufacturing process, designs, as well as functional properties are far from equivalent to this invention.
This invention allows user to enjoy aromatherapy and the vaporization of essential oils without any additional containers, top adaptors or catchments systems which all other systems require, while maintaining a most efficient center column for the vapors to travel through. This product is simply heated and the particulates or essential oils are applied or entered from the top open environment for use. This simplifies the entire process for aromatherapy and the atomization/vaporization of particulates or essential oils.
This invention uses a funned shape titanium top bowl to increase efficiency, allowing for the quickest vaporization of essential oils though a very high surface area along with a deep catchment basin, allowing it to hold a greater quantity of essential oils at once then any other product. This mechanism catches the vapors from inside the top titanium bowl and pulls them though the center titanium column eliminating the need for outer glass adaptors to trap and direct the vapors into the user's desired glass vessel. Also, the titanium “nail” of this invention has a shaft which is threaded into a ceramic adaptor which serves as a heat sink, allowing the users to continually heat the top of the product without the bottom ceramic adaptor getting too hot to be held in a glass vessel of choice. Due to the recessed angled extrusions on the ceramic adapter, it fits all produced glass vessels at 14/18 mm sizes, such as glass water pipe inlets.
The solid grade 2 titanium construction of the “nail” portion of this invention in its preferred form, allows for even distributed heat which provides faster heating then glass and is more efficient in the vaporization process. The user can change the desired temperature, accommodating a wide rage of possible vaporization needs. With all other products on the market requiring many other adaptors and parts to function, this part can work alone or with a ceramic heat sink to make it adaptable for many more applications.
The invention works by heating up the top material which is preferably made of, but not limited to, grade 2 titanium. Grade 2 titanium is selected as the main material for use due to its beneficial material properties of high melting point (3*10^3 degrees F.), low thermal expansion (5 microstrain/degrees F.) and low specific heat (0.13 BTU/Lb*F). Titanium has a very low coefficient of thermal expansion and high melting point is extremely beneficial for use because the part can be heated to over 1000 degrees F., and with a low thermal expansion it can be threaded into a ceramic part made of Alumina without over expanding or cracking the ceramic part due to internal stress. This is also due to Alumina's beneficial material properties with a higher melting point then titanium of (3.8*10^3 F.) and a thermal expansion similar to that of titanium at (4.5 microstrain/degrees F.). Grade 2 titanium is also chosen due to its purity and health benefits. Titanium (especially grade 2) does not emit or exhaust any harmful gasses or elements when heated, as do many steels, brasses and coppers, and is considered commercially pure. This makes titanium a good choice for use in vaporization.
The titanium part is preferably made up of two separate machined parts which are joined together into one final part. The top portion of the titanium part is shaped in a bowl shape with thin walls and bottom to allow for quick heating and cooling cycles. Having a thinner thickness of material allows this top part, where the essential oils are applied, to be heated faster and cooled quicker. The bowl shape of this product versus many other designs, which either implement glass tubes or flat surfaces, combines and improves upon preexisting technology. This bowl design allows users the ease of a tube design in allowing this product to be used and implemented at any angle due to the sidewall support which allows use without the essential oils falling out of the unit or off of the hot vaporization surface. Yet also the grade 2 titanium material heats up much faster then any glass would due to its metal characteristics heating much more quickly and efficiently.
The angled top bowl is also more efficient then other designs due to its large surface area created by the catchment basin along with the angled sidewalls. When the top is heated and the essential oils are applied/introduced into the bowl for vaporization, it can run down the entire sidewall vaporizing all the way down as well as in the bottom catchment basin. This is a significant improvement over other titanium nail technology which only implements flat surfaces for the vaporization of essential oils.
The second part of the invention which is fixed to the titanium top bowl is the titanium column/shaft. The titanium shaft is also made of but not limited to grade 2 titanium. This shaft fixtures up into the inside of the top bowl to allow for an interfering of the two parts, creating a “basin” on the bottom of the top bowl. On the bottom of the top bowl is where these two parts are fixed together or laser welded or otherwise bonded or fastened, conjoining them as one part. On the center column, there are a few different designs which have been implemented, the benefits of which will be described below. On the first design a straight column is used with a center hole for the vapors to travel through. This is done so that the center column can remain hot and allow the vapors not to re-condense as they traveled down the center column and out of the part. The bottom of this center column on previous designs has been an angled design to allow it to fit into different water pipes or other vapor handling devices. Other designs have implemented threading down the center column on the outside to both function as heat fins to cool the overall unit and transfer less heat to the bottom of the unit while also allowing users to screw their part into and out of the ceramic adaptor which allows users to use the product at any height while also making it easier to take apart for cleaning or travel. This adjustable height is very important as it allows users to both raise the top titanium bowl when they wish to use the product or thread it down for compact and easy transportation. Also, knurling has been implemented on the top of the center column before the top bowl to allow users easier grip in screwing the titanium part into and out of the ceramic holder/adaptor. The top of the titanium column that fits into the top bowl has slits or angled cuts in the column. These cuts allow for increased airflow and turbulence into the column to improve the overall function of the product.
The ceramic adaptor is currently produced from Alumina but is not limited to this material. This is a beneficial material to use as it acts as a heat sink with the titanium screwed into it, stopping most of the heat which is in the titanium from traveling or shocking the glass of the water pipe inlet or other vapor handling device which this product can sit in. The other purpose of producing these ceramic parts is to allow this titanium vaporizer to fit in a variety of water pipes. Currently there are four different size water pipe adaptors which are commonly produced and sold in the U.S. In having two well designed ceramic adaptors, this one titanium part can fit universally into nearly every water pipe produced. Many other products that are offered only fit one type of water pipe, so an individual must buy at least four separate products to enjoy aromatherapy and vaporization.

Other further objects of the present invention will become apparent from a careful reading of the included drawing figures, the claims and detailed description of the invention.
Referring to the drawings, wherein like reference numerals represent like parts throughout the various drawing figures, reference numeral 10 is directed to a vaporizer assembly (
Solid or liquid substances to be vaporized are inserted into a highly heated basin portion at an upper end of the vaporizer assembly 10 (along arrow A of
In essence, and with particular reference to
The adapter 50 includes a hollow core 60 which can receive the shaft 40 therein. Preferably, the shaft 40 is threaded along with the hollow core 60, in a complementary fashion, such that rotation of the nail 20 (along arrow D of
More specifically, and with continuing reference to
The bowl 30 is preferably an open topped enclosure including a substantially planar floor 34 with side walls extending up to a lip 32. The hole 36 is formed in the floor 34, preferably near a midpoint thereof, and which floor preferably has a circular form. The shaft 40 can thus extend up through this hole 34 and preferably extends up into the bowl 30 somewhat, but below the lip 32 and above the floor 34. The bowl 30 preferably has side walls which taper slightly so that the lip 32 is circular in form and wider than the floor 34. The opening inboard of the lip 32 defines an entrance into the bowl 30 into which substances to be vaporized can be placed (such as along arrow A of
The shaft 40 is an elongate rigid structure extending from an upper tip 42 to a lower tip 48. A bore 45 passes from the upper tip 42 to the lower tip 48 to provide a hollow vapor input path from the bowl 30. Preferably, a knurled band 44 is provided on a portion of the shaft 40 closer to the upper tip 42 than to the lower tip 48, and configured just below where the shaft 40 passes through the hole 36 in the bowl 30. The knurled band 44 defines a portion of the shaft 40 which can be securely gripped by a user, such as to facilitate rotation (about arrow D of
The shaft 40 has outer threads 46 provided on portion of the shaft 40 below the knurled band 44. These outer threads 46 are complemental with threads which are either on the adapter 50 itself or fixed relative to the adapter 50, such that rotation of the nail 20 (about arrow D of
While the threads 46 provide part of a preferred form of a means to adjust position of the nail 20 relative to the adapter 50, other position adjustment means could alternatively be provided. For instance, a clamp could releasably grasp the shaft 40 at a desired height, inserts could be intermediately placed in various sizes or numbers to space the nail 20 a desired distance from the adapter 50. The adapter could be provided with nail rests which could be adjustably placed where desired to control a position of the nail 20 relative to the adapter 50.
With continuing reference to
A hollow core 60 in the form of a through bore passes vertically through a center of the adapter 50. This hollow core 60 is sized to allow the shaft 40 of the nail 20 to pass therethrough. In one variation (
With either variation, the upper body 52 preferably features a rim 70 extending upwardly from the upper body 52 and with slits 72 extending vertically through the trim 70. The rim 70 defines a portion of the upper body 52 of the adapter 50 which is a significant distance from locations where the adapter 50 is in contact with the nail 20, for conduction heat transfer. Because the adapter 50 is formed of a material with a relatively low rate of heat transfer, and with slits 72 in the rim 70, upper portions of the rim 70 will tend to be a significantly lower temperature than other portions of the adapter 50 and relative to a temperature of the nail 20. In some instances, a user might be able to directly hold the adapter 50 at this rim 70 portion. In other instances, a user with relatively lightweight gloves or other limited additional thermal insulation can readily handle the adapter 50 through the rim 70, even when the nail 20 is exceptionally hot. A gap 74 inboard of the rim 70 helps to isolate the rim 70 from portions of the adapter 50 which are in direct contact with the nail 20, to thus further insulate the rim 70 from temperatures associated with the nail 20.
With particular reference to
The nut 190 includes an inside threaded hole 194 which is sized to coact with the outer threads of the nail 120. The nail 120 is similar to the nail 20 of the embodiment of
With the alternative vaporizer assembly 110, it is not required that threads be formed in the material forming the adapter 150. Furthermore, if the nut 19 is formed of a titanium alloy similar to the material forming the nail 120, various differences in materials which might alter performance can be avoided, such as differing rates of thermal expansion, so that a smooth threading interface can be maintained at a variety of different temperatures. The nut 190 would typically have an outer surface 192 which is knurled or otherwise roughened so that it tends to engage the surfaces of the recess 180 within the adapter 150. As an alternative, the recess 180 and outer surface 192 of the nut 190 can be somehow keyed or faceted in a complementary fashion to prevent relative rotation therebetween. As a further alternative, some form of adhesive or other bonding agent could be utilized to secure the nut 190 within the adapter 150.
In one use mode, the nail 120 is height adjusted while in the adapter 150 by rotation. In another use mode, the nail 120 is removed from the adapter 150 and the nut 190 is rotated to a desired position and then the nail 120 and nut 190 are replaced into the adapter 150.
With particular reference to
Uniquely with this second alternative vaporizer assembly, the shaft 240 preferably includes a covered upper tip 242. Slots in a side of the shaft 240 just below the upper tip allow for vapors to be drawn into the hollow bore of this shaft 240. Such a covered upper tip 242 can prevent material from falling down into the bore in the shaft 240 potentially without having sufficient time for the material to vaporize. The bore 245 can also include a barrier with port holes 244 therein to further insure that material does not fall through the bore 245 without becoming vaporized.
Annular fins 246 are also optionally shown extending radially from the shaft 240 of the nail 220. These annular fins 246 could be provided on any of the nail embodiments such as the nail 20 (
The adapter 250 is configured to include an outer skirt 290 which tapers to a wider form at a lower end thereof opposite to a configuration of the adapter 50 (
The various different unique features of the alternative embodiments for the vaporizer assembly 10, 110, 210 can be individually included in the various other alternative embodiments of this invention disclosed herein.
In use and operation, a user will initially remove the nail 20 from the adapter 50 and place the nail 20 adjacent to a heat source. The nail 20 is heated, typically until the material from which the nail 20 is formed is glowing red (or other colors generally indicative of the degree of heating of the nail 20). If desired, the nail 20 can remain within the adapter 50 during this heating process with heat directed to the bowl 30 portion of the nail 20 and allowed to transfer through conduction heat transfer to other portions of the nail 20.
A material to be vaporized is then placed within the bowl 30. This material can be solid or liquid. When the material to be vaporized comes into contact with surfaces of the nail 20, the extreme temperature differential causes rapid phase change of the material into a gaseous vapor. In some instances the material undergoes some degree of chemical reaction, such as an oxidation reaction or other reaction which is driven by the high temperature which the material attains, as well as the material's contact with oxygen or other elements in the air, or other substances which might be present (e.g. water). In other instances, the material is merely heated so that it undergoes a phase change from solid or liquid into gaseous. The resultant vapor is in the generally proximity of the bowl 30. Through suction forces down through the pipe inlet tube T, these vapors are drawn through the bore 45 and the shaft 40 of the nail 20 and down into the pipe inlet tube T (arrows B and C). If the vaporizer assembly 10 is utilized merely resting upon a horizontal surface, the vapors merely emanate out of the bowl 30 into a surrounding environment.
While a pipe inlet tube T is shown such as might be provided on a water pipe, a respirator, nebulizer, or other device for supporting the delivery of vapors to a user for inhalation, might be utilized along with the vaporizer assembly 10 of this invention, as well as the vaporizer assemblies 110, 210 of alternative embodiments. The nail 20 can be rotated relative to the adapter 50 to provide a desired degree of nesting between the nail 20 and adapter 50. Such adjustment might be provided to alter a rate at which the nail 20 cools, or to change the distance through the overall assembly 10. In one embodiment with the alternate vaporizer assembly 110, the nut 190 is first adjusted into a desired position on the shaft 140 in advance of heating. When the nail 120 has been heated the nail 120 can be dropped into the adapter 140 and will drop into a desired distance when the nut 190 drops into the recess 180. In such an embodiment position adjustment occurs by rotating of the nut 190 upon the shaft 140 until it is at a desired position, rather than rotating the nail 120 after it has been nested into the adapter 150.
This disclosure is provided to reveal a preferred embodiment of the invention and a best mode for practicing the invention. Having thus described the invention in this way, it should be apparent that various different modifications can be made to the preferred embodiment without departing from the scope and spirit of this invention disclosure. When structures are identified as a means to perform a function, the identification is intended to include all structures which can perform the function specified. When structures of this invention are identified as being coupled together, such language should be interpreted broadly to include the structures being coupled directly together or coupled together through intervening structures. Such coupling could be permanent or temporary and either in a rigid fashion or in a fashion which allows pivoting, sliding or other relative motion while still providing some form of attachment, unless specifically restricted.
