Abstract

Embodiments of the present disclosure relate to a fan system. The fan system is adapted to be coupled to a mask, and comprises a fan configured to facilitate an airflow passing through a filter material of the mask and a controller configured to control the fan to operate with a drive signal. The controller is further configured to obtain operation data of the fan driven by a testing drive signal, and determine a type of the mask based on the operation data. In this case, the type is associated with a filtration characteristic of the mask. In accordance with embodiments of the present disclosure, a type of a mask can be automatically identified by the controller based on the operation data of the fan obtained from the fan without additional components, thereby providing a cost saving and design friendly solution.
