Dynamically temperature and shape changing fan with native air purification and room sterilization

Abstract

The present disclosure discloses a fan having a main hub and a main shaft. Each of the multiple fan blades has a detachable shaft to which a joinery assembly is detachably connected. The joinery assembly is configured to cause either angular shift or speed variation or both of the fan blades to impact air attack and air fluid dynamics of the fan on the basis of either of user input parameters or data collected from the multiple sensors or both. Thus, the fan dynamically changes either angular shift or speed variation or both of the fan blades to impact air attack and air fluid dynamics of the fan to provide the suction and circulation of cold or warm UV and HEPA purified air through the fan blades.
