Neck fan
A neck fan includes: an inner shell, disposed near the neck; an outer shell, connected to the inner shell and disposed opposite to the inner shell and away from the neck. The outer shell and the inner shell cooperatively define a receiving space; a plurality of fan assemblies. Each fan assembly is received in the receiving space and connected to the inner shell and the outer shell. The inner shell defines a plurality of air inlets, located near and facing towards the neck. At least a part of the receiving space serves as an air duct communicating with the air inlets. Each fan assembly corresponds to the air inlets. Each fan assembly is configured to intake air from an outside of the neck fan through the air inlets and to further drive the air to flow into the air duct.
