Neck fan

Abstract

A neck fan includes a neck hanging body for hanging on a neck of a human body and fan assemblies. First air channels are defined inside the neck hanging body. First air inlets and first air outlets are defined on the neck hanging body. The first air inlets and the first air outlets are communicated with the first air channels. Fan accommodating structures are protruded from one the side, facing the human body, of the neck hanging body. Each of the fan assemblies is at least partially installed in a corresponding fan accommodating structure to reduce spaces for accommodating the fan assemblies in the neck hanging body. Namely, a volume and a thickness of the neck hanging body is reduced. The fan assemblies are configured to enable external air to enter the first air channels from the first air inlets and blow out along the first air outlets.
