Misting fan

Abstract

A misting fan includes a fan assembly, a nozzle assembly, a motor, a battery pack, and a battery pack holder. The nozzle assembly is configured to spray mist in front of an air outlet of the fan assembly. The motor is configured to drive the fan blade assembly to rotate. The battery pack is configured to supply energy to the motor. The battery pack holder receives the battery pack. A fan housing is configured to rotate about a vertical axis relative to the battery pack holder. The battery pack holder does not rotate about the vertical axis along with the fan housing.
