TECHNICAL FIELD OF THE INVENTION
The technical field relates to a device for vaporization of phyto materials and more specifically to a device for aromatherapy vaporization.
BACKGROUND OF THE INVENTION
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 released the essential oils therefrom. 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, an aroma or vapor is given off, which is then inhaled by a user for its therapeutic benefits. Devices that provide such operation are generally known as vaporizers. Different phyto materials release vapors at different temperatures. Some release vapors at 120 degrees Celsius, whereas others at 220 degrees Celsius. Ideally the predetermined temperature is less than a combustion temperature of the phyto material or loose leaf material.
Many herbal vaporization devices on the market utilize a heating chamber in order to heat herbal leaf material in order to vaporize its contents so that desired oils and other flavor materials can be separated from the leaf material in order to be consumed by a user of the device in a vaporized form.
Unfortunately, many of these herbal vaporization devices have long heating times as well as are large in size and are not convenient to be carried around.
It is therefore an object of the invention to provide an aromatherapy vaporization device that overcomes the aforementioned deficiencies.

In the first mode of operation the housing first portion first surface 181a and the housing second portion first surface 181b are approximately inline. An angle of the hinge as measured between the housing first portion first surface 181a and the housing second portion first surface 181b is at an approximately 180 degrees (FIG. 1A) and for operating in a second mode of operation (FIG. 1D) where the angle of the hinge is at an approximately 2 degree and the housing first portion first surface 181a and the housing second portion first surface 181b are facing opposite each other.
Referring to FIG. 1B, the AVD 100 is shown in the first mode of operation from a top view where the housing first portion first surface 181a and the housing second portion first surface 181b are removed for clarity. As is illustrated, the housing first portion 101 has an inhalation aperture 188 disposed proximate a first end 101a thereof and has a second end 101b opposite the first end 101a. A heating chamber first portion 102 is disposed proximate the second end 101b of the housing first portion 101 having a first conductive heating element 801 disposed therein. A fluid pathway 109 is disposed between the inhalation aperture 188 and the heating chamber first portion 102.
A heating chamber first portion aperture 102a is provided for fluidly coupling of the heating chamber first portion 102 with the fluid pathway 109. A first battery 104 disposed within the housing first portion, wherein preferably the battery is a lithium polymer battery. A first control circuit 105 electrically coupled with the first battery 104 and a first conductive heating element 801, which is disposed within the heating chamber first portion 101. A first electrical contact 805 is disposed within the first housing portion 101 and protruding through the housing first portion first surface 181a and electrically coupled with the first control circuit 105. A second electrical contact 806 is disposed within the second housing portion 110 and protruding through the housing second portion first surface 181b and is also electrically coupled with the first control circuit 105.
The heating chamber first portion 102 is for receiving of phyto material 419 in the first mode of operation and for heating of the phyto material 419 in the second mode of operation. A transition from the first mode of operation into the second mode of operation of the AVD 100 is shown in FIG. 1C where the angle of the hinge is reduced in the transition.
A heating chamber second portion 103 is disposed in the housing second portion 110, for in the second mode of operation, as is shown in FIG. 1D, the heating chamber second portion 103 and the heating chamber first portion 102 form an approximately closed heating chamber having an ambient air input port 123. As is illustrated in FIG. 1D, a gap 868 is formed between the heating chamber first portion 102 and the heating chamber second portion 103 for allowing of ambient air to enter into the heating chamber first and second portions 102 and 103.
In use, in the second mode of operation, the first electrical contact 805 and the second electrical contact 806 are electrically coupled with each other and electrical current flows from the first battery 104 to the first conductive heating element 801 and the phyto material 419 is heated to a predetermined temperature, such as 160 degrees Celsius to 230 degrees Celsius, and vapor 422 is emitted from the heating of the phyto material 419 and is captured in the heating chamber second portion 103 and flows through the heating chamber first portion aperture 102a and propagates through the fluid pathway 109 for inhalation from the inhalation aperture 188. In the second mode of operation the hinge is at an approximately 2 degree angle and the housing first portion first surface 181a and the housing second portion first surface 181b are facing opposite each other with the phyto material 419 disposed therebetween.
Referring to FIGS. 1B and 1C, a second conductive heating element 802 is disposed within the heating chamber second portion 103 and electrically coupled with the control circuit 105, wherein in the second mode of operation at least one of the first conductive heating element 801 and the second conductive heating element 802 heat the phyto material 419 for the releasing of vapor 422 therefrom. Furthermore as shown in FIG. 1B, disposed proximate to the at least one of the first electrical contact 805 and the second electrical contact 806 is at least a first magnet 888 and a second magnet 890. The at least a first magnet 888 and a second magnet 890 operate in order to maintain the AVD 100 in the second mode of operation. In the case where there is one of the a first magnet 888 and a second magnet 890, a metal plate is used and disposed on the opposite side for providing for a magnetic coupling to result.
Preferably the fluid pathway 109 comprises a thermally conductive material to cool the vapor and air propagating therethrough to a temperature that is comfortable for inhalation by a user. So for example the thermally conductive material comprises aluminum or copper or stainless steel and a temperature that is comfortable for inhalation for the user is approximately under fifty degrees Celsius.
Preferably at least one of the first and second conductive heating elements 801 and 802 are manufactured from a low thermal inertia conductive heating element and comprises a metal material that comprises a nickel metal alloy. Optionally a ceramic pancake heater is also envisaged for at least one of the first and second conductive heating elements 801 and 802. Having a low thermal inertia conductive heating element allows for quick heating and is advantageous when the user is impatient.
Because the first embodiment of the invention uses conduction heating to heat the phyto material 419, preferably the phyto material 419 is compressed between the heating chamber first portion and the heating chamber second portion 102 and 103 in the second mode of operation.
Referring to FIG. 1B, preferably the housing first portion comprises a recharging port 113 electrically coupled with the first battery 104 for receiving of electrical current for recharging thereof. Having the ability to recharge the first battery 104 is not essential, however if this recharging port 113 is not provided then the AVD 100 becomes a disposable device. The AVD 100 as such therefore starts to heat the phyto material 419 upon the housing first portion first surface 181a and the housing second portion first surface 181b facing each other with the first and second electrical contacts 805 and 806 are in electrical communication with each other and stops heating when the first and second electrical contacts 805 and 806 are other than in electrical communication with each other. This allows the user to customize their experience by opening and closing of the housing first portion 101 with respect to the housing second portion 110. The holding together of the housing first portion 101 with respect to the housing second portion 110 can be performed either manually by the user in the second mode of operation or the magnets are utilized to maintain an attraction between the housing first portion 101 and the housing second portion 110.
FIG. 1E illustrates an AVD 200 in accordance with a second embodiment of the invention and in a first mode of operation. Shown in FIG. 1E, is a temperature sensor 898 that is thermally coupled proximate one of a heating chamber first portion 202 and a heating chamber second portion 203. The AVD 100 is formed from the housing first portion 101 having a housing first portion first surface 181a, which is removed for clarity in this drawing, the housing first portion 101 coupled with a hinge 807 to a housing second portion 110 having a housing second portion first surface 181b, which is removed in this figure for clarity. In the first mode of operation the hinge 807 is at an approximately 180 degrees angle. The housing first portion 101 includes a recharging port 213 electrically coupled with the first battery 104, in this embodiment the recharging port 113 is a micro USB port, however a USB C port is also envisaged. A first control circuit 205 is provided and electrically coupled with the first battery 104 and also coupled with at least one of a first conductive heating element 901 and a second conductive heating element 902. In this embodiment, a temperature adjustment dial 999 is provide and electrically coupled with the first control circuit 205 for in combination with the temperature sensor 898 for providing a controlled heating to the at least one of the first conductive heating element 901 and the second conductive heating element 902. Providing of controlled heating allows for heating of the phyto material 419 in such a manner that combustion thereof is potentially avoided. The temperature adjustment dial 999 is for example formed from a variable resistor that provides a variable resistance to the first control circuit 205 for analog temperature adjustment of the first and second conductive heating elements 901 and 902.
A switch 707 is also optionally provided and electrically coupled with the first control circuit 205 for enabling and disabling the provision of controlled heating to the at least one of the first conductive heating element 901 and the second conductive heating element 902 in dependence upon a switch control signal.
An ambient air input port 223 is provided and in fluid communication with the second conductive heating element 902, where optionally there is a one-way airflow valve 223a, such as an umbrella valve, to allow air to flow only in a single direction into the heating chamber first and second portions 202 and 203 when in the second mode of operation. Preferably with the use of the one-way airflow valve 223a, there is a high temperature silicone rubber seal disposed between the heating chamber first and second portions 202 and 203 so that the vapor and ambient air 422 does not flow out of the heating chamber first and second portions 202 and 203 when in the second mode of operation other than flowing through the fluid pathway 109.
Preferably at least one of the first and second conductive heating elements 901 and 902 are manufactured from a low thermal inertia conductive heating element that comprises a metal mesh as is shown in FIG. 1E.
Preferably the battery is lithium polymer battery. There are some lithium polymer batteries that are approximately 1 mm thick. The conductive heating element in accordance with the embodiments of the invention is made from a thin nickel containing resistive metal plate or a thin nickel containing resistive mesh as is shown in FIG. 1E for the first and second conductive heating elements 901 and 902 where preferably the thickness is about 0.1 mm. A spiral or coil heating element is also envisaged or also a ceramic pancake heater element as options.
In the first mode of operation because the heating chamber first and second portions 102 and 103 are other than coupled together, it makes for easy cleaning and emptying of vaporized phyto material that is leftover within the heating chamber first and second portions 102 and 103.
It is advantageous to have a vaporizer that is a small form factor as well as one that is discrete to bring along for various adventures. It is envisaged that the vaporization device in accordance with the embodiments of the invention is about 5 mm thick and has a size of about 80 mm×50 mm. Of course, if possible a thickness of less than 3 mm is also envisaged where it can be stored in a wallet because the size resembles that of a pair of credit cards stacked together. Also one that provides for easy cleaning and for having the vapor that is emitted therefrom to not be too hot for inhalation by the end user.
Numerous other embodiments are envisaged without departing from the spirit or scope of the invention
