Abstract
The application discloses a portable fan, which comprises a fan shell, a fan assembly assembled in the fan shell, and an air inlet and an air outlet of the fan shell being communicated with the fan assembly. A plurality of first static blades are arranged in the fan assembly, a plurality of second static blades are arranged at the air outlet of the fan shell, and a plurality of third static blades are arranged between the first static blades and the second static blades. The three-stage static blades are adopted to effectively separate the airflow, so that the flow path of the airflow in the fan is more orderly. The first static blades in the fan assembly, the second static blades at the air outlet, and the third static blades between the first static blades and the second static blades can all hinder the rotational movement of the airflow, gradually reduce the spiral rotation kinetic energy of the airflow in the flow process, reduce the energy loss caused by the rotation, and improve the airflow flow efficiency.
