This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,856,990.

Background and Problem Solved

Existing electronic atomization devices suffer from liquid leakage and insufficient liquid supply in their liquid supply systems. The present invention builds upon the original patent's capillary liquid conducting and atomizing unit, addressing these limitations by introducing novel features and enhancements that improve the overall performance and efficiency of the device.

Novelty and Inventive Step

The novelty of the present invention lies in the introduction of multiple sub-channels in the capillary liquid absorbing channel, the use of a heat-resistant material for the housing, the incorporation of a temperature control module, and the hydrophilic coating treatment of the capillary liquid absorbing channel. These features, individually and in combination, provide a significant improvement over the original patent and existing electronic atomization devices.

Alternative Embodiments and Variations

Alternative embodiments of the invention may include varying the shape and size of the sub-channels, using different materials for the housing, or incorporating additional features such as sensors or monitoring systems to further enhance the device's performance and efficiency.

Potential Commercial Applications and Market

The enhanced capillary liquid conducting and atomizing unit has significant commercial potential in the fields of electronic atomization, including but not limited to e-cigarettes, medical devices, and industrial applications, where improved efficiency, thermal stability, and reduced liquid leakage are critical.
