Solution Overview

Problem

Conventional devices for vaporizing volatile substances, such as fragrances and active agents, require high temperatures and large structures, leading to complex designs and increased production and assembly costs due to the separate heating block and wick configuration.

Innovation Solution

Integrating the electrical heating element into the container itself, allowing for direct heat conduction to the capillary element, thus reducing the need for high temperatures and enabling a compact design with reduced production complexity.
