Portable vaporizer




Title: Portable vaporizer.
Abstract: A vaporizer and method of vaporizing a botanical material is described. Embodiments of the apparatus include a self-contained, fully enclosed, battery operated vaporizer having an air inlet and a mouthpiece. The vaporizer includes a window for viewing a botanical material contained therein and a heating element that is also visible through the window and through an air inlet. The vaporizer also includes a push-button switch that rapidly provides power to heat air, which is then drawn through the botanical material by inhaling. Embodiments of the method include utilizing a push-button switch for heating vaporizer air and viewing the glow of the heating element as a signal that the vaporizer is ready for use. ...

BACKGROUND

OF THE INVENTION

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.

BRIEF

SUMMARY

- Top of Page


OF THE INVENTION

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.

These features together with the various ancillary provisions and features which will become apparent to those skilled in the art from the following detailed description, are attained by the vaporizer of the present invention, preferred embodiments thereof being shown with reference to the accompanying drawings, by way of example only, wherein:
