Bladeless fans with a nozzle

A bladeless fan, comprising:

• a base comprising an interior having an impeller disposed therein;
• a support rod extending from the base, the support rod having an inner lumen in fluid communication with the interior of the base;
• and
• a fan arm rotatably coupled to the support rod, the fan arm having first and second rotatable fan arm portions positioned on opposite ends of the fan arm, and first and second nozzles positioned on the first and second rotatable fan arm portions, respectively, the first and second nozzles having first and second fan lumens, respectively, in fluid communication with the inner lumen;
• wherein rotation of the impeller is configured to generate airflow that flows into the interior of the base, through the inner lumen of the support rod, and through the first and second fan lumens to be emitted from the first and second nozzles, and
• wherein the first nozzle has a teardrop-shaped cross-section and tapers toward a first nozzle opening positioned along a narrowest point of the cross-section.
