Vapor delivery devices and methods

A vapor delivery device comprising:

• a housing;
• a liquid delivery system;
• a vaporizing system;
• and an electrical power system;
• substantially within the housing;
• a lever pivotally supported on or in the housing;
• the vaporizing system having an electrically powered vaporizing element electrically connected to the electrical power system;
• the electrical power system having a switch for switching on and off electrical power to the vaporizing element;
• the liquid delivery system including a pressurized liquid reservoir;
• a tube having a pump section and an outlet section;
• a first valve and a second valve;
• with the reservoir connected to the second valve via the pump section of the tube, and the outlet section of the tube extending from the second valve to the vaporizing system;
• and with the lever positioned to pivot to close the first valve, compress the pump section of the tube, open the second valve, to move liquid from the pump section of the tube through the second valve and the outlet section to the vaporizing element in the vaporizing system, and actuate the switch.

A method for delivering a dose of vapor, comprising:

• pivoting a lever in a first direction, with the lever movement:
• pinching off a liquid supply tube at a pinch point;
• squeezing the supply tube between the lever and a fixed rigid surface;
• opening a valve allowing liquid to move from the supply tube into a vaporizing element;
• and
• closing a switch to deliver electrical current to the vaporizing element, with the vaporizing element vaporizing the liquid.

A vapor delivery device comprising:

• a housing;
• a vaporizing element in the housing;
• a wick adjacent to the vaporizing element;
• an electrical power source in the housing;
• a switch for switching on and off electrical power to the vaporizing element from the electrical power source;
• a liquid reservoir in the housing;
• a tube connecting the liquid reservoir to the wick;
• a valve in the housing associated with the tube;
• a button on the housing, with movement of the button actuating the switch and the valve.
