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.

A neck fan includes an arc-shaped shell and a fan assembly. The arc-shaped shell is configured to be worn around a neck of a user. The shell has a first side and a second side opposite to the first side. Each of the first side and the second side defines air inlets. At least one of the first side and the second side defines air outlets. The shell further defines a receiving space, and the receiving space includes an air duct communicating with the air inlets and outlets. The fan assembly is received in the receiving space and configured to drive the air to flow from the air inlets of both sides, through the air duct, reaching the air outlets.

A neck fan, configured to be worn around a neck of a user, 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, wherein 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. Each of the inner shell and the outer shell defines a plurality of air inlets, each fan assembly corresponds to both the air inlets in the inner shell and the air inlets in the outer shell, each of the plurality of fan assemblies is configured to intake air from an outside of the neck fan into the receiving space through the corresponding plurality of air inlets.
