The technical field relates to temperature measurement and more specifically to a device for temperature measurement to be used in conjunction with equipment for vaporization of phyto materials.
Aromatherapy generally uses essential oils, which are extracted from phyto materials, such as leaves of plants, for therapeutic benefits. These essential oils are either massaged into the skin or can be inhaled. In some cases, the phyto materials are heated in order to release the essential oils therefrom through an aerosol. By heating these phyto materials at predetermined temperatures, essential oils and extracts are boiled off, depending upon the temperature at which these phyto materials are heated, a vapor or aerosol is given off, which is then inhaled by a user for its therapeutic benefits. Devices that provide such operation are generally known as vaporizers. There are also extracts available that are derived from the phyto material or loose-leaf aromatherapy materials and these have a consistency of honey and are typically highly purified forms. Normally these extracts are vaporized at temperatures between 500 to 700 degrees Fahrenheit.
Devices that process these concentrated phyto material extracts typically include a waterpipe, or bong, that has an input port and an inhalation aperture with a fluid pathway formed therebetween. Normally a metal or ceramic or quartz vaporization element is inserted into the input port and it is heated with a torch to get it to reach a temperature of about 500 to 700 degrees Fahrenheit.
Phyto material extract is applied to the vaporization element and a user inhales from the inhalation aperture of the waterpipe, which results in vaporized phyto material and ambient air to flow into the inhalation aperture and into the fluid pathway for being cooled by the water which is typically contained within this fluid pathway to cool the vapor air mixture.
Because the heating is performed by a torch, such devices do not typically vaporize the concentrated phyto material extracts and instead combust them by heating the extracts to a much too high temperature. Heating to combustion temperatures usually results in smoke and other combustion by products to be inhaled by an end user.
This combustion of course isn't a safe process as there are many harmful byproducts released in the combustion process. Glass vaporization surfaces are preferable over ceramic as these materials offer an improved taste of vapor that maybe generated from the heating of the extract by the vaporization element.
Measurement of the temperature of the vaporization element is typically not measured using temperature measuring equipment and usually the process is a visual or time based one. For example, the metal or ceramic or glass vaporization element is heated with a torch until it glows red hot and then a timer is set and a countdown period is initiated whereby the vaporization element is allowed to cool in order for this vaporization element to reach a temperature that is cooler that perhaps doesn't combust the extract.
Other means are to use a temperature gun or temperature probe, such as a k thermocouple probe and meter, to probe the vaporization element prior to its use, however these are bulky in size and tend not to be very portable and easy to take on the road. Furthermore, many temperature guns do not measure accurately because of the small size of the vaporization element as well as the emissivity of the vaporization element and the temperature gun not being calibrated for this type of non-contact temperature measuring of the vaporization element.
Using a timer is not very scientific and taking a temperature probe on the road is not very portable. As such, it is therefore an object of the invention to provide a temperature measurement device that overcomes the aforementioned deficiencies.
It is therefore an object of the invention to provide a temperature measurement device that overcomes the aforementioned deficiencies.

Embodiments described herein relate generally to temperature measurement devices for use with equipment for vaporization of phyto material and phyto material products. Phyto material products may be derived from phyto materials such as the leaves or buds of cannabis plants.
Phyto material is often vaporized by heating the phyto material to a predetermined vaporization temperature. The emitted phyto material vapor can then be inhaled by a user for therapeutic purposes. The vapor may often be emitted at a temperature that can be uncomfortable for a user to inhale. Accordingly, it may be desirable to provide to an end user a device that allows for the user to determine a temperature a vaporization element prior to an application of phyto material to the vaporization element. I may also be desirable to provide for a digital reading to the end user.
The vaporization elements are known as bangers in some cases and these are manufactured from materials such as ceramic, quartz glass, borosilicate glass or ceramic. In some cases, the vaporization element is made from an annular ring (
The vaporization elements are characterized by having a surface, or a floor, onto which phyto material extract is disposed for creation of a vapor therefrom for the user then to inhale the vapor from the inhalation aperture 421a as the vapor propagates through the water pipe fluid pathway 421c and is cooled and filtered by water that is stored in the water reservoir 421 d of the water pipe 421.
In the current state of the art, in order to use the vaporization element with the water pipe 421 with the phyto material extract, the vaporization element is typically heated by a blow torch. The blow torch imparts thermal energy onto the vaporization element, which is heated to a desired point by the end user. Usually these vaporization elements are heated to a point where, if they are manufactured from glass (such as quartz glass), the glass glows red hot, or in the case of metal to a point where the metal also starts to glow. This is beneficial to in order to burn off any residue from the vaporization element.
Typically post heating, the user then sets a timer in order to allow a fixed amount of time for the vaporization elements of cool, say for example 30 seconds, before placing the phyto material extract onto the vaporization element for the vaporization thereof.
Unfortunately, these vaporization elements are typically heated much too high by the end user and not allowed sufficient time to cool prior to being used by the end user. As a result, when phyto material extract is applied to the vaporization elements, it is typically combusted.
Through titration the user determines whether the vaporization element is too hot or too cold after they inhale the vapor generated by the vaporization element heating the phyto material extract. If the vaporization element is too hot, then the extract is overheated and combusted and the user should then determine, they should wait longer post heating of the vaporization element before applying extracts the vaporization element.
In some cases when there's not enough of a vapor produced when the extract is placed on the vaporization element, the user then determines that the vaporization element should be heated longer or the user should not wait as long for the vaporization element to cool before placing phyto material extract onto the vaporization element.
This method significantly relies on titration, and is other than scientific. It would be advantageous to approximately know a temperature of the vaporization element prior to the application of phyto material extracts to its surface. For example, for high temperature use a desired temperature range is about 500-600° F., and for low temperature use a desired temperature range is about 350-450° F. In some embodiments the temperature may be 585° F. as may be indicated in
Some of the more advanced vaporization devices on the market offer a temperature readout and claim to provide for an accurate vaporization surface temperature, however it would be further beneficial for the end user to be better informed about the temperature at which they are vaporizing their phyto material extracts. The more advanced vaporization devices seldom offer accurate temperature readings that are within +/−5 degrees Celsius. In some cases, it would also be beneficial to know a temperature at which they are vaporizing their phyto materials that are derived from leaf.
The TMD 100 may further include a base unit 101 disposed at a second end thereof 100b. An arm 102 may be provided for coupling the temperature sensor 121 at the first end 100a with the base unit 101 at a second end 100b. The temperature sensor 121 disposed at the first end 100a may be electrically coupled with the base unit 101 at the second end 100b of the arm 102. The first end of the arm 102a may be for contacting the floor 422a of the vaporization element 422 or in some cases a sidewall of the of the vaporization element 422.
The base unit 101 may include a control circuit 130 electrically coupled with the temperature sensor 121 and a battery 131 and a temperature indication unit 199, which may include an electronic display module 132 for providing a digital temperature reading. The control circuit 130 may be for receiving of the first temperature signal from the temperature sensor 121 and in some embodiments may be for displaying a visual representation of the temperature signal on the temperature indication unit 199. The temperature indication unit 199 may be a digital character display module or a LED color indication module that indicates a temperature through color changing or combinations thereof. In some embodiments, an auditory indication may also be provided based on the first temperature signal as part of the temperature indication unit 199. In some embodiments the temperature indication unit 199 may include a LED indicator displaying a visual representation of the temperature signal through color changing, where when the temperature of the vaporization element floor 422a is hot and above 700 Fahrenheit the LED is red and when its below 400 Fahrenheit the LED is illuminated blue and varying colors therebetween.
When the TMD 100 is used in conjunction with a heating element or the vaporization element, the base unit 101 may be disposed below the temperature sensor 121 such that the temperature sensor 121 or the arm proximate the first end 100a may create a contact point with the floor 422a of the vaporization element, such as is show in
Referring to
In some embodiments the first arm proximate the first end 100a is fabricated from a ceramic or thermally less conductive material then a metal material. In some embodiments this material can withstand temperatures that are about 1000 Fahrenheit without melting or deforming and in some embodiments this material may be a platinum RTD temperature sensor that is embedded within a metal housing as is known in the art.
In some embodiments the temperature sensor has may have a contact area with the vaporization element that is a smaller area than a cross sectional area of the arm such as to take away minimal heat from the vaporization element. In some embodiments the temperature sensor may protrude past the first and 100a, such as a K type thermocouple bead or a housed thermistor or other type of sensor that exhibits a temperature coefficient of resistance. In some embodiments the arm is manufactured from a metal material or a combination of metal and non-metal materials.
In some embodiments the U shaped bend 179 is disposed within a first third 100c, of the TMD 100, a second third 100d is the a portion of the arm 102 and the base unit 101 is found within a third portion 100e. Where in use the base unit 101 hangs approximately below the floor 422a of the vaporization element 422 when the first end 100a is engaged with the floor 422a of the vaporization element 422. The weight of the TMD 100 may provide for an improved thermal communication between the temperature sensor 121 proximate the first end 100a.
Referring to
In accordance with embodiments of the invention, TMD may provide a visual color indication of the temperature of the floor 422a of the vaporization element 422 and also optionally provides a digital display of the temperature of the floor of the vaporization element. In some embodiments, a power button 123 is provided to turn the TMD 100 to an ON functionality and to an OFF functionality conserve battery power. Optionally a mode button 124 is provided to change a temperature reading being shown when the temperature indication unit 199 includes the electronic display module 132. from Celsius to Fahrenheit.
In some embodiments the control circuit and temperature sensor is auto activated so that when a large temperature change is detected by the temperature sensor it awakes the control circuit to function as programmed and then when the temperature decrease is detected, for example when the TMD is removed, the control circuit enters a lower power mode, however this may consume additional power in standby mode and deplete the battery at a faster rate than when the ON functionality and to an OFF functionality conserve battery power is implemented within the control circuit.
In some embodiments, the control circuit comprises a Bluetooth or Wi-Fi module for transmitting of wireless temperature data to a wireless receiver, such as a smartphone. Optionally, the arm proximate the first end thereof made from a ceramic or material with reduced thermal conductivity. Preferably the temperature sensor comprises a platinum RTD temperature sensor, where preferably the temperature sensor is able to operate up to 1500 Fahrenheit and in some embodiments its able to operate up to 1200 Fahrenheit where material for fabrication of the arm proximate the first end is able to withstand these temperatures.
In some embodiments the unit may include a housing that is translucent or transparent material and a colored LED is provided for illuminating the housing, wherein a color of the LED is indicative of the temperature of the vaporization element floor as determined by the temperature signal. In other embodiments the used may set an alarm within the control circuit and the temperature indication unit may provide an auditory or visual or vibration alarm to the end user when the vaporization surface is at their optimal temperature.
In use of the TMD in accordance with the embodiments of the invention, the user heats the vaporization element by a blow torch. The blow torch imparts thermal energy onto the vaporization element, which is heated to a desired point by the end user. Usually these vaporization elements are heated to a point where, if they are manufactured from glass (such as quartz glass), the glass glows red hot, or in the case of metal to a point where the metal also starts to glow. This is beneficial to in order to burn off any residue from the vaporization element. Post heating, the user then hangs the TMD with the first end proximate the floor of the vaporization element and waits for the temperature to be indicated on the temperature indication unit to a level which is preferably. Then the TMD is removed and the user is able to enjoy their phyto material extracts with the vaporization element. Furthermore, the In some embodiments the rotatably mounted of the arm with respect to base unit 101 allows for the hot first end of the arm to be angled away from a surface on which the TMD is rested post temperature measurement. In some cases the first end may be at a temperature that is close to a thousand degrees Fahrenheit and may cause combustion if placed on a wooden surface.
For the type of temperature sensor, a RTD (resistance temperature detector) is potentially envisaged for temperature measurement by correlating the resistance of the RTD element with temperature. In some cases the RTD consists of a film or a wire wrapped around a ceramic or glass core and in some cases platinum is used and some RTDs can also be made from nickel or copper. Preferably a platinum RTD is utilized as this offers a fairly linear temperature output signal that is accurate (0.1 to 1° C.) across a range of about 25° C. to around 600° C. Potentially a thermocouple, suck as a K type thermocouple is utilized, which consists of two wires of different metals connected at two points. The varying voltage between these two points reflects proportional changes in temperature. These sensors are nonlinear in the temperature signal they provide and may require use with a lookup table and they are also not as accurate as platinum RTD, where they have an accuracy from about 0.5° C. to 5° C., and they also operate across a wide temperature range of about 25° C. to 1750° C.
Some of the advantages of the embodiments of the invention are the TMD 100, 200 is portable, it hangs with the first end within a bowl or recess of the vaporization element, similar to a candy cane, which ensures that the temperature sensing element is in thermal contact with the surface of the vaporization element where the first end may be in a corner of the vaporization element or proximate a flat surface of the vaporization element.
The weight of the TMD resting on the temperature sensor therefore may ensure that the vaporization element may be in thermal communication for optimal heat transfer to the temperature sensor and therefore for providing of accurate temperature readings of the vaporization surface as well as a provision of a fast temperature response to the user.
Furthermore, the TME in accordance with embodiments of the invention has advantages over infrared thermometers because it is able to directly contact the vaporization element with the temperature sensor at its first end. Every material that is used for the vaporization element will radiant heat or infrared radiation at its own specific rate period. For example, ceramic or quartz glass or titanium may radiate at different heat levels as perceived by the infrared thermometer. Shiny surfaces such as titanium will also affect the readings as indicated by the infrared thermometer as will matte surfaces. As such, because of the various types of materials and the surface properties and the vaporization element temperatures, these vaporization elements will appear to have varying temperatures as perceived by the infrared thermometer. Furthermore, the proximity of the infrared thermometer to the vaporization surface and the measurements pot size of the infrared thermometer also play a role and an accuracy of the temperature that is displayed by the infrared thermometer.
It is therefore preferable to use the TMD 100, 200 in accordance with embodiments of the invention for measurement of the temperature of the vaporization element as opposed to an infrared thermometer.
Other temperature measurement devices that do not have a U shaped bend as advantageously described within the embodiments of the invention that may have a straight temperature probe that extends from the base unit will fall out from the vaporization element and may not be preferable as they will be held in place by the user and cannot be hang in place on the vaporization element and left there until the optimal temperature of the vaporization element is reached and then end user then removes the TMD and uses the vaporization element for vaporization of their phyto material extracts.
In some embodiments having a flexible coupling between the first arm and the second arm allows for the TMD to be converted into various orientation of the first end with respect to the base unit as required by the user. In some embodiments the flexible coupling is in the form of a flexible gooseneck tubing.
The TMD in accordance with embodiments of the invention is also applicable for use with electronic nails (or e-nails) where there is a vaporization element that is heater by a heating coil where it is desired to know the temperature of the vaporization element.
In some embodiments the battery 131 may be a lithium polymer battery or a coin cell battery and in some embodiments the battery may be rechargeable.
Other embodiments are also envisaged where the TMD may be used with a leaf vaporization device where the first end is placed within a bowl of the leaf vaporization device proximate the vaporization element thereof.
