如图2和图3所示，网罩10还包括后网12，后网12上开设有过孔121，供风电机41的输出轴411穿过过孔121伸入网罩10内，主动风叶42套设在供风电机41的输出轴411上，并位于前网11和后网12之间，伸入网罩10内的输出轴411还与位于前网11和后网12之间的马达31的转子转轴311连接，供风电机41的输出轴411带动马达31的转子转轴311和主动风叶42同步转动。
如图1和图3所示，风扇还包括电机支架50和主板60，供风电机41设置在电机支架50上，主板60安装在电机支架50上，主板60和显示面板24上均设置有无线传输模块，主板60与显示面板24通过无线传输模块通讯连接。这样，用户通过显示面板24进行人机交互操作，显示面板24与主板60通讯连接，从而通过主板60控制供风电机41的工作状态。
需要说明的是，主板60连接有电源线，与市电连接，实现电源供电。
可选地，显示面板24上设置有按键，用户通过按键输入信息，与主板60进行信息交互。
可选地，显示面板24用于显示风扇的供风模式等信息。
如图1和图3所示，风扇还包括电机罩70，电机罩70罩盖在供风电机41、电机支架50和主板60的外侧，从而保护供风电机41、电机支架50和主板60，提升风扇的外观美感和使用寿命。
如图2和图3所示，电机罩70具有让位开口71，让位开口71与过孔121相对设置，后网12与电机罩70连接，其中，让位开口71用于避让供风电机41的输出轴411。
可选地，风扇还包括蓄电池，发电部30通过蓄电池与显示部20连接。这样，发电部30可以将产生的电能存储在蓄电池内，以便在风扇刚启动时为显示部20供电。
实施例二
与实施例一的区别在于，如图6所示，发电部30包括马达31和从动风叶32，从动风叶32与马达31的转子转轴311驱动连接，发电元件为从动风叶32；驱动部40包括供风电机41和主动风叶42，其中，供风电机41驱动主动风叶42转动，以使风扇送风，且主动风叶42与从动风叶32相对设置，以驱动从动风叶32转动。这样，供风电机41的输出轴411带动主动风叶42转动，主动风叶42驱动从动风叶32转动，从动风叶32带动转子转轴311转动，转子转轴311转动使线圈内的磁通量发生变化而产生感应电动势，从而使发电部30产生电能，为显示部20供电。
本申请实施例二提供的风扇，利用主动风叶42转动产生的风能发电，这样，供风电机41的输出轴411不需要与马达31的转子转轴311直接连接，能够更加灵活地设置马达31和供风电机41的位置。
本申请提供的风扇能够利用发电部30和驱动部40自动发电，从而为显示部20有效地供电，同时，不影响主动风叶42的正常运行，显示部20的续航能力强。
