Abstract: A personal vaporizer has a vaporizer case defining a vaporizer interior, a vaporization chamber within the vaporizer interior, an air flow passage from one or more air intake openings in the case to the vaporization chamber, a vaporization mixture flow passage extending from the vaporization chamber to an exit port, and a heating arrangement having at least one heating element disposed within the vaporization chamber. The heating arrangement is connected to a power source for selective activation by a user. A first fluid reservoir is configured for retaining a first vaporizable fluid within a first reservoir interior and a second fluid reservoir is configured for retaining a second vaporizable fluid within a second reservoir interior. A fluid transport arrangement is configured for transporting the first and second vaporizable fluids from the first and second fluid reservoirs into the vaporization chamber.

Abstract: A personal vaporizer has a case, a vaporization chamber, a fluid reservoir configured for retaining a vaporizable fluid, a fluid transport structure, a heating element disposed within the vaporization chamber, an air flow passage from one or more air intake openings in the case wall to the vaporization chamber, a vaporization mixture flow passage extending from the vaporization chamber to an exit port, and an activation circuit connected to the heating element. The activation circuit includes a power source, a vaporizer control processor, an authorization control device that is selectively connectable to and disconnectable from the activation circuit, and an activation mechanism configured and positioned for manual operation by a user to selectively complete the activation circuit when the authorization control device is connected and the use authorization criteria are met.

Abstract: A micro-vaporizer has a main body in which are disposed a vaporization chamber and a vaporizable liquid reservoir. A heating element disposed within the vaporization chamber is configured to vaporize liquid drawn from the liquid reservoir. An air flow passage from an inlet portal to the vaporization chamber provides a first fluid communication path between the vaporization chamber and an ambient environment external to the main body. A vaporization products flow passage from the vaporization chamber to an exit port provides a second fluid communication path between the vaporization chamber and the ambient environment. An air-permeable liquid barrier disposed within the air flow passage is configured to inhibit passage of the vaporizable liquid through the air flow passage.
