Abstract
Description
- 1. Field of the Invention
- The present invention generally relates to the field of vaporizers for consuming botanical materials, and more particularly to an apparatus and method for using a portable, self-contained vaporizer for heating the materials to a temperature sufficient to release the volatile components without combustion.
- 2. Discussion of the Background
- Devices for consuming botanical materials, including but not limited to tobacco, flowers, botanical blend, or aromatic herbs, commonly ignite the botanical materials, requiring that the consumer inhale products of combustion along with any volatile compounds that are present. For many botanical materials it is the volatiles, such as the nicotine present in tobacco, that provide a physiological response in the consumer, while the combustion products may actually be harmful.
- Prior art vaporizers commonly employ a continuous heating source such as a butane-powered flame, a butane powered catalytic burner, or an electrical resistive heater. The heat source in many such devices is conductive as it is in direct contact with the material or the receptacle containing the material. This may result in high temperatures, leading to singing and charring of the botanical material near the heat source.
- Further, many prior art vaporizers require several minutes of heat-up time as they need to heat both the mass of the botanical material and a holder of the material to a desired temperature before they can extract volatile vapors.
- Further, since the heating is typically continuous, rather than on-demand, many existing vaporizers use their power inefficiently as they are often providing heat to maintain a steady state of elevated temperature that does not correspond to the user's intended duty-cycle of intermittent inhalation of the vapors produced.
- One embodiment of the present invention overcomes the disadvantages of prior art by providing a vaporizer that entirely contains a botanical material to be consumed.
- Another embodiment of the present invention overcomes the disadvantages of prior art by providing a vaporizer having an upper portion that may be removably placed on a lower portion to contain a botanical material to be consumed. In one embodiment, the upper and lower portions are held in place with magnets.
- Yet another embodiment of the present invention overcomes the disadvantages of prior art by providing an enclosed vaporizer having a window for viewing a botanical material contained therein. In one embodiment, the window also allows the extracted vapor and glow from a heating element to be viewed.
- One embodiment of the present invention overcomes the disadvantages of prior art by providing an enclosed vaporizer that allows the glow from a heating element to also be viewed through an air inlet.
- Another embodiment of the present invention overcomes the disadvantages of prior art by providing a vaporizer having a heating element suspended in a transparent heating chamber that allows for the transmission of light generated by the heating element of the device.
- Yet another embodiment of the present invention overcomes the disadvantages of prior art by providing an enclosed vaporizer having a heating element suspended in a transparent heating chamber that is integrated with and concentric to the material chamber.
- One embodiment of the present invention includes a computer controlled temperature regulation system that allows for the proper vaporization temperatures for aromatic herbs, flowers, and tobacco.
- Another embodiment of the present invention includes a vaporizer having rechargeable battery that is removable by the user.
- It is one aspect of the present invention to provide vaporizer to provide a user with a vapor from a botanical material. The vaporizer includes a housing; a heater substantially within the housing including an electrical energy storage device, a user-operable switch, a heating element, and an electrical circuit including the electrical energy storage device, the user-operable switch, and the heating element, where the electrical circuit is adapted to provide energy from the electrical energy storage device to the heating element when the user-operable switch is actuated. The vaporizer further includes a passageway with the housing, the passageway including an air inlet, a heater section to provide thermal contact with air within the heater and the heating element, a receptacle for containing a botanical material, and an air outlet. The user may thus actuate the user-operable switch and inhale through the outlet to draw air external to the vaporizer to sequentially, heat air in contact with the heating element to a heated air temperature, at least partially vaporize the botanical material with the heated air, then provide at least a portion of the vaporized botanical material through the outlet to the user.
- It is another aspect of the present invention to provide a method of providing a vapor of a botanical material using a vaporizer. The method includes manually actuating the vaporizer, where the vaporizer includes stored electric energy, a receptacle for containing the botanical material, and a flow passageway extending from an inlet, through a manually actuatible heater to accept the stored electric energy and heat air, through the receptacle, to an outlet; and inhaling through the outlet. Air is thus drawn external to the vaporizer into the passageway and sequentially, has the air temperature increased in the heater, heats and extracts a vapor from the botanical material, and provides the vapor to the user.
- It is yet another aspect of the present invention to provide a vaporizer to provide a user with a vapor from a botanical material. The vaporizer includes a heating element, and a passageway including an air inlet; a heater section to provide thermal contact with air within the heater and the heating element; a receptacle for containing a botanical material; a window to transmit thermal radiation from the heater section to the user, and an air outlet. The user has a visual cue that inhaled air may be heated to a temperature sufficient to vaporize the botanical material.
- It is one aspect of the present invention to provide a method of providing a vapor of a botanical material using a vaporizer, where the method includes manually actuating the vaporizer, where the vaporizer includes a receptacle for containing the botanical material, and a flow passageway extending from an inlet, through a heater to heat air, through the receptacle, to an outlet, and a window to allow a user to view thermal radiation from the heater; and when a user perceives a glow from the heater through the window, inhaling through the outlet. The user thus has a visual cue that inhaled air may be heated to a temperature sufficient to vaporize the botanical material.
- a receptacle for containing the botanical material, and a flow passageway extending from an inlet, through a heater to heat air, through the receptacle, to an outlet, and a window to allow a user to view thermal radiation from the heater, the method comprising: manually actuating the heater; and when a user perceives a glow from the heater through the window, inhaling through the outlet. The user thus has a visual cue that inhaled air may be heated to a temperature sufficient to vaporize the botanical material.

Withpower switch 201 in the “off” setting, all electronics invaporizer 100 are powered off. Withpower switch 201 in an “on,” “low temperature” or “high temperature” setting,processor 725 has a corresponding stored on temperature (TON), low temperature (TL) or high temperature (TH) which are target temperatures for controlling a temperature measured bytemperature sensor 942. As described above,temperature sensor 942 measures the air temperature just before the heated air flows throughbowl 640. -
Indictor lights 307 may include lights that are programmed to provide an indication of the operation ofvaporizer 100. Thus, for example and without limitation, indicator lights 307 may include a dim green light that is powered to indicate thatvaporizer 100 is powered on in a low temperature setting, a bright green light that is powered to indicate that the vaporizer is powered in a high temperature setting, blinking blue light to indicate that the vaporizer is charging, a red light to indicate that battery power is low, and a solid red light to indicate the device is overheated and has been automatically shut down. - In addition, with
power switch 201 in an “on,” “low temperature” or “high temperature” setting, and with push-button switch 109 pressed,processor 725 provides signals topower controller 727 to provide electric power frombattery 731 toheating element 715. In certain embodiments,processor 725 uses a control algorithm, such as a PID control algorithm, topower heating element 715 such that the temperature, T, measured bytemperature sensor 942 is maintained at the temperature indicated bypower switch 201. - The target temperature of
temperature sensor 942 is selected to effectively drive off volatiles from the botanical material. While not meant to limit the use of the present invention, the Table I contains effective vaporization temperatures of some botanical material -

For multiple temperature settings, such as a “low temperature” and “high temperatures,” the low temperature setting maybe suitable for vaporizing low temperature volatiles such as tobacco and have a temperature in the range of from 150° C. to 165° C., with a value, for example of 150° C., 155° C., 160° C., or 165° C. The high temperature setting maybe suitable for vaporizing higher temperature volatiles, such as ginseng, and have a temperature of 190° C. to 205° C., with a value, for example of 190° C., 195° C., 200° C., or 205° C. - The following are examples of the user of
vaporizer 100. With reference toFIGS. 1 and 3 , withpower switch 201 in an “off position,” a user graspslower portion 220 in one hand and places their thumb inrecess 309 to removeupper portion 210. With reference toFIG. 6 , a user may then clean the various internal surfaces andbowl 640, and place a fresh sample of a botanical material in the bowl.Upper portion 210 may then be securely placed on top oflower portion 220. - As shown in
FIGS. 6 and 7 , a user may, at any time, look throughwindow 107 to verify the presence of a botanical material. - Next, the user switches
power switch 201 to an appropriate non “off” setting (such as “on,” “low temperature,” or “high temperature”). - Next, the user presses push-
button switch 109. Within a few seconds,control electronics 720 has provided sufficient power to raise the air neartemperature sensor 942 to the target temperature, as stored withinprocessor 725. The glow fromheating element 715 may be seen by the user throughwindow 107 and/or throughair inlet 105. For certain botanical materials the extracted vapor may also be viewed throughwindow 107. - With the visible indication of a proper temperature, the user may then inhale through
mouthpiece 103. Air is then drawn intoair inlet 105, throughpassageway 713, through the botanical material inbowl 640, betweengrooves 635 andsurface 601, alongsurface 601 intoopening 607, and then throughopening 311 to the user's mouth. - The majority of power provided to
heating element 715 heats air withinpassageway 713, and thus the botanical material withinbowl 640 is vaporized convectively as the hot air flows through the botanical material. - The surfaces which contact the heated air as it flows between
surface 601 andupper portion 210 will act as a “heat sink,” causing the gases to cool from high temperature ofheating element 715 to approximately room temperature. After inhaling, the user then releases push-button switch 109, which reduces the power thoughheating element 715. - It will be understood that the apparatus described herein includes, but is not limited to, certain digital and analog components. It will be understood that the invention is not limited to any particular implementation, programming technique, or combination of analog or digital components, and that the invention may be implemented using any appropriate devices or techniques for implementing the functionality described herein.
- Reference throughout this specification to “one embodiment” or “an embodiment” means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, appearances of the phrases “in one embodiment” or “in an embodiment” in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner, as would be apparent to one of ordinary skill in the art from this disclosure, in one or more embodiments.
- Similarly, it should be appreciated that in the above description of exemplary embodiments of the invention, various features of the invention are sometimes grouped together in a single embodiment, figure, or description thereof for the purpose of streamlining the disclosure and aiding in the understanding of one or more of the various inventive aspects. This method of disclosure, however, is not to be interpreted as reflecting an intention that the claimed invention requires more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive aspects lie in less than all features of a single foregoing disclosed embodiment. Thus, the claims following the Detailed Description are hereby expressly incorporated into this Detailed Description, with each claim standing on its own as a separate embodiment of this invention.
- Thus, while there has been described what is believed to be the preferred embodiments of the invention, those skilled in the art will recognize that other and further modifications may be made thereto without departing from the spirit of the invention, and it is intended to claim all such changes and modifications as fall within the scope of the invention.
