Ionizing fan with airflow rectification device

Abstract

An ion fan with an airflow rectification device includes a housing unit, a first ion fan unit, and a control unit. The housing unit includes a first outer shell and a second outer shell, which together define an accommodating space. The second outer shell has a first air outlet. The first ion fan unit includes a filter, a fan, a discharge needle assembly, and an airflow rectification device. The airflow rectification device has a guide channel. The guide channel communicates with the first air outlet. The diameter defining the guide channel is a diametrical length, and the length of the guide channel along the airflow direction is an axial length, which is less than the diametrical length. The control unit is signal-connected to the first ion fan unit and used to control the operation of the first ion fan unit.
