Abstract
A fan includes a column assembly, a fan head, a hinge assembly, and a support structure connected to the fan head and the column assembly. The hinge assembly includes a first connection member and a second connection member which are hinge-connected to each other. The first connection member is connected to the column assembly, and the second connection member is connected to the fan head. The fan head is configured to rotate around the support structure, and an axis around which the fan head rotates relative to the support structure coincides with an axis around which the first connection member and the second connection member rotate relative to each other.
