Understanding Patent US8205622B2
US8205622B2, titled “Electronic Cigarette,” describes a two-part vaping device designed to resemble a traditional cigarette. The invention consists of:
- An electronic inhaler that houses the power source and control mechanisms.
- An electronic atomizer that contains the liquid to be vaporized.
The inhaler and atomizer are connected via electric connectors, allowing them to function as a unit. The device is activated when a user inhales, triggering an electric airflow sensor that controls the atomization process.
