  • Patent number: 10881131
    Abstract: This non-combusting flavor inhaler is provided with a control unit which, as an instruction to a battery, outputs to the battery a prescribed instruction instructing the battery that the amount of aerosol vaporized by a vaporizer unit should fall within a desired range. The control unit stops power supply from the battery to the vaporizer unit once a prescribed period has elapsed since the start of supplying power to the vaporizer unit. The prescribed period is shorter than the upper limit value of a standard puff period, which is derived from a statistic of the user's puff period.

  • Patent number: 10603459
    Abstract: A vaporizer and vaporizer cartridge for inhaling vapors from vaporized oil. The vaporizer has a mouthpiece for use by a user to inhale the vapors. The mouthpiece is connected to a cartridge which contains the oil to be vaporized and the apparatus for vaporizing the oil. The vaporizer cartridge contains a reservoir of the oil which flows down to a wick, which is heated by a heating coil to a temperature necessary to vaporize the oil. Under the wick is a residue basin which collects any oil which fails to vaporize. The residue basin is placed at an optimal distance from the wick such that when the next user initiates another draw on the vaporizer, the un-vaporized oil in the residue basin is vaporized. Below the cartridge is a battery component that provides power to a heating coil which heats the wick to vaporize the oil. Air flows up from below the cartridge on one side, then cross-flows across the wick and residue basin, and up the other side of the cartridge to the mouthpiece.
