AI Technical Summary
Technical Problem
Existing air-cooling devices face challenges in achieving efficient cooling while maintaining portability and user comfort, as refrigerant-based systems consume high energy and occupy space, and evaporative coolers require large absorbent media and can lead to mold growth.
Method used
An air-cooling device with an absorbent medium and an agitator that moves relative to each other to release droplets, utilizing a motorized drive system and protruding elements to enhance evaporation efficiency and reduce medium size, allowing for compact design and mold prevention.
Benefits of technology
The device achieves efficient cooling with a smaller absorbent medium, reduces mold risk, and eliminates the need for additional airflow post-use, enhancing user experience and portability.

Abstract
Provided is an air-cooling device (10) comprising an absorbent medium (12) configured to absorb a liquid, and an agitator (14) for contacting a surface of the absorbent medium. The absorbent medium and the agitator are moveable relative to each other to cause the agitator to agitate the surface of the absorbent medium and thereby release droplets of the liquid from the absorbent medium. Once released from the absorbent medium, the droplets of the liquid can evaporate to cool air.
