[0025] Before describing the embodiments in detail, it should be understood that the present invention is not limited to the detailed structures or element arrangements described below or in the accompanying drawings. The present invention may be implemented in other ways. Furthermore, it should be understood that the wording and terminology used herein are for descriptive purposes only and should not be construed as limiting. The terms "comprising," "including," "having," and similar expressions used herein mean to include the items listed thereafter, their equivalents, and other additional items. In particular, when describing "an element," the present invention does not limit the number of elements to one, but may include multiple elements.

[0026] like Figure 1-6 As shown, this utility model provides a fan head and a rotating fan. Specifically, the fan head 100 can be installed on a portable bracket 200. The fan head 100 has a battery inside, a charging port, and an independent switch. The fan head 100 includes a housing 101, and a motor 102 is installed inside the housing 101. A first support column 103 and a second support column 104 are fixed on both sides of the motor 102, and the ends of the first support column 103 and the second support column 104 away from the motor 102 are connected to the housing 101.
