  • Personal vaporizer with liquid supply by suction
    Patent number: 10506828
    Abstract: A personal vaporizer having a pressure-induced liquid supply that allows a user to draw liquid from a liquid reservoir through applying a suction force on the mouthpiece. The amount of liquid drawn is proportional to the pressure induced, and proportional to the amount of vaporization a user may desire.

  • Micro-vaporizer heating element and method of vaporization
    Patent number: 9877509
    Abstract: A heating element for a micro-vaporizer including a heating element, and a wetted surface or a fluid storing membrane that fit snuggly onto an outer surface of the heating element. Vaporization is achieved by applying a current through the heating element that is higher than an inherent power rating of the heating element to generate heat that vaporizes fluids supplied to the wetted surface or stored in the fluid storing membrane.
