Electronic Vaping System
Patent No. EP3863452 (titled "Electronic Vaping System") was filed by AYR on Oct 14, 2019. The application was issued on Sep 17, 2025.
Patent Summary
This vaping system comprises an automatically re-fillable liquid reservoir that supplies liquid to an atomizer. It features a liquid level sensing sub-system that detects the liquid amount or level by measuring electrical characteristics of the reservoir that vary based on the liquid volume. A fluid transfer system, controlled by the sensing sub-system, automatically transfers liquid into the reservoir. In one embodiment, the sensing sub-system utilizes sensor plates to measure capacitance, which increases as the liquid level rises. A capacitance measuring circuit, typically located in a docking station, activates a pump to refill the reservoir when the measured capacitance falls below a predefined threshold, ensuring the device is replenished without manual user intervention.
