  "country": "US",
  "title": "How a Device Delivers Aerosol with Controlled Airflow During Inhalation",
  "original_title": "Systems and methods of aerosol delivery with airflow regulation",
  "summary": "This patent describes an aerosol delivery device that heats a substance from a cartridge to release an aerosol into an airflow passage specifically when a user inhales, and includes a rechargeable internal power source.",
  "what_it_does": "This device delivers an aerosol, which is like a fine mist, to a user. It has a mouthpiece with an opening for air to come out and a path for air to flow through. A main body, called a housing, holds a replaceable container, or cartridge, which contains a substance that can turn into an aerosol and a heating part, called a vapor element. When the cartridge is in place, a controller tells the vapor element to heat the substance, releasing the aerosol into the air path, but only when the user breathes in through the mouthpiece. The device also has a built-in battery that can be recharged using an external power source through a special connector.",
  "what_it_does_not_cover": [
    "Does not cover aerosol delivery devices that do not use a replaceable cartridge for the aerosolizable substance.",
    "Does not cover devices where the aerosolizable substance is not heated by a dedicated vapor element.",
    "Does not cover devices that release aerosol continuously or without being triggered by a user's inhalation.",
    "Does not cover devices that lack an internal power source that can be recharged from an external source.",
    "Does not cover devices without a specific airflow passage extending between an inlet and an outlet in the mouthpiece."

  "abstract": "An example aerosol delivery device includes a mouthpiece having an airflow outlet, and an airflow passage extending between an airflow inlet and the airflow outlet. The example aerosol delivery device further includes a housing configured to receive a cartridge that includes an aerosolizable substance and a vapor element configured to heat the aerosolizable substance, and an internal power source configured to provide electrical power. The example aerosol delivery device further includes a controller coupled to the internal power source to receive a portion of the electrical power and configured to, when the cartridge is installed at the housing, cause the vapor element of the cartridge to heat the aerosolizable substance to release an aerosol into the airflow passage during an inhalation through the airflow outlet, and a connector configured to receive power from an external source to recharge the internal power source.",
