Abstract
In a vapor delivery device, a carrier or an expedient for an active ingredient is a liquid that can be vaporized by exposure to a concentrated, focused heating point using an efficient electrical power source. The device may have a vaporizing element and an electrical power source in a housing. A switch controls supply of electrical power to the vaporizing element from the electrical power source. A tube connects a liquid reservoir to the vaporizing element. A first valve, a second valve, and a pump are generally associated with the tube. A lever pivotally supported on or in the housing may be positioned to operate the first valve, the second valve, the pump and the switch, via pivoting movement of the lever. The device efficiently provides a uniform dose of vapor with each actuation.
