第一送风部2包括第一电机21、第一风扇22、风机支架23和环形导风隔栅24。第一电机21驱动第一风扇22运转。风机支架23和环形导风隔栅24安装在本体1上，风机支架23设置在环形导风隔栅24与本体1之间。在风机支架23和环形导风隔栅24内分别设置环形风道25，在环形导风隔栅24内还设置凹槽26。第一电机21通过第一电机螺丝26安装在风机支架23上。凹槽26设置在环形导风隔栅24的顶部中间，摇头组件3和抬头组件4设置在该凹槽26中。
所述摇头组件3包括摇头电机31、相互啮合的摇头齿轮32和摇头齿圈33、转盘底座34和转盘35。摇头电机31通过摇头电机螺丝固定在环形导风隔栅24上，在环形导风隔栅24上设置摇头电机安装孔213。摇头齿轮32固定在摇头电机轴上，摇头齿圈33设置在转盘35的内圈上。转盘底座34与转盘35通过转盘螺丝相互固定。
在转盘底座34上设置转动滑槽37，在转动滑槽37中设置滑动螺丝38，滑动螺丝38将转盘底座34与环形导风隔栅24连接在一起。在本实施例中，在转盘底座34上设置有位于同一圆周上的三段转动滑槽37，在每段转动滑槽37分别设置有一个滑动螺丝38。摇头电机31通过摇头齿轮32与摇头齿圈33的相互啮合带动转盘底座34和转盘35同时沿滑动螺丝38转动。在滑动螺丝38与转盘底座34的接触面之间设置滑动垫片36，既减少转盘底座34转动时的摩擦阻力，同时将转盘底座34进行上下限位，提高转盘底座34转动时的平稳性。
请同时参照图6、图7至图8所示，在所述环形导风隔栅24上设置至少三组位于同一圆周上的轴承定位轴27，在每个轴承定位轴27上设置轴承28，在转盘底座34的底面设置滑道39，每个轴承28均沿该滑道39滑动。这种结构可以保证环形导风隔栅24与转盘底座34的旋转同心度，减少偏心量。
轴承26过盈地安装在轴承定位轴27上。在所述环形导风隔栅24上安装轴承定位轴27的通孔11，轴承定位轴27贯穿通孔29。所述轴承定位轴27与通孔29之间是过盈配合。所述轴承定位轴27设置定位轴轴肩210，定位轴轴肩210抵靠在环形导风隔栅24的底面上。
风机支架23设置支撑台211。支撑台211支撑在轴承定位轴27的底面，防止轴承定位轴27松脱。
在所述环形导风隔栅24上设置凸环212，凸环212设置在环形导风隔栅24的顶面，且位于每个通孔29的顶部，轴承28的内圈281抵靠在凸环212上。
在所述转盘底座34上还设置台阶312，台阶312位于滑道39的底面，台阶312抵压在轴承28的外圈282上。
所述抬头组件4包括上关节组件41、下关节组件42和抬升臂43。抬升臂43的上端与第二送风部5活动连接，其下端与摇头组件3活动连接。上关节组件41带动第二送风部5绕Y轴转动，下关节组件42驱动抬升臂43抬起和降落。Z轴与第一风扇22的转动轴线一致，Y轴为垂直于Z轴方向并向外。
请参照图12所示，所述下关节组件42包括下关节电机421以及相互啮合的下关节齿轮422和下关节齿圈423。下关节电机421通过下关节电机螺丝和电机外罩424固定在转盘35上，下关节齿轮422设置在下关节电机轴上。在下关节齿轮422一端设置齿轮轴肩425。本实施例中，在齿轮轴肩425上套接轴肩轴承426，使得轴肩425转动更顺滑。在轴肩轴承426的下方设置支撑块427用于支撑轴肩轴承426，否则，支撑块427直接支撑齿轮轴肩425。支撑块427起到支撑作用，防止抬升臂43受力较大时下关节齿轮422会往下移影响抬升臂43的抬起和降落准确性
下关节齿圈423设置在抬升臂43上，在抬升臂43的下端还设置两个同轴的下关节转轴4210。本实施例中，在每个下关节转轴4210上套接下关节轴承428，使得下关节转轴427转动更顺滑。在每个下关节轴承428外套接下关节转轴套429，否则，下关节转轴套429直接套接在下关节转轴427上。下关节转轴套429通过轴套螺丝固定在转盘35上。
下关节电机421通过相互啮合的下关节齿轮422和下关节齿圈423带动抬升臂43绕下关节转轴427转动，实现抬升臂43的抬起和降落。在所述下关节转轴427上还设置下关节扭簧4211。设置下关节扭簧4211的作用是下关节扭簧4211施加向下的压力减少抬升臂43在抬起和降落时的晃动量。
所述上关节组件41包括上关节电机411、以及相互啮合的上关节齿轮412、上关节齿轮组413和上关节输出齿轮414、上关节转轴415。上关节电机411固定在抬升臂43上，上关节齿轮412设置在上关节电机轴上。上关节齿轮412通过上关节齿轮组413带动上关节输出齿轮414转动，上关节输出齿轮414设置在上关节转轴415上，上关节转轴415安装在抬升臂43的上端，上关节转轴415与第二送风部5相连接。在上关节转轴415上套接上关节轴承416，减少与抬升臂43之间转动摩擦阻力。两个关节轴承416分别设置在上关节转轴415的两端。
上关节电机411通过相互啮合的上关节齿轮412、上关节齿轮组413和上关节输出齿轮414带动第二送风部5绕上关节转轴415转动。在上关节转轴415上还设置上关节扭簧417。设置上关节扭簧417的作用是上关节扭簧417施加向上的压力，减小第二送风部5在抬起时电机所需的力，同时减少第二送风部5在抬起和降落时的晃动量。
请再同时参照图3和图4所示，第二送风部5用于将从环形导风隔栅24出来的风再吹向更远的区域和更大的范围。所述第二送风部5包括第二电机51、第二风扇52、前风罩53、后风罩54、外罩56和固定板57。第二电机51和后风罩54分别固定在固定板57上，第二风扇52设置在第二电机轴上且位于前风罩53和后风罩54之间。前风罩53套装在后风罩54上，外罩56套装在前风罩53上。
在上关节转轴415的中部还设置四方轴段418，第二送风部5的固定板57上设置与四方轴段418相配合四方孔58。
在所述转盘35上还设置用于放置抬升臂43的收纳槽310，在转盘35顶面设置转盘盖板311，在所述抬升臂43的两侧分别设有左抬升臂盖板431和右抬升臂盖板432。
在环形导风隔栅24的顶部周缘设置第一防夹手的感应线圈7。在收纳槽310的顶部周缘设置第二防夹手的感应线圈8。第一防夹手的感应线圈7和第二防夹手的感应线圈8分别与主控系统（图中未示出）进行信号连通。第一防夹手的感应线圈7和第二防夹手的感应线圈8分别感知进入该区域的人手并将感知信号反馈到主控系统，主控系统控制抬抬头组件4的启动或关闭。设置第一防夹手的感应线圈7和第二防夹手的感应线圈8给本风扇提供双重安全保护，防止抬头组件4和第二送风部5在降落过程中夹到用户手指，极大地提高其安全性。
 本发明的实施方式
本发明还公开一种空气净化器，在所述空气净化器内使用了如前所述的具有摇抬头功能的风扇。
请同时参照图1、图2、图3、图14和图15所示。在所述空气净化器中设置空气过滤器6，所述空气过滤器6位于第一送风部2的正下方，空气过滤器6的出风口与第一送风部2的环形风道25连通，空气过滤器6的进风口通过设置在空气过滤器壳体9上的导风孔10连通壳体9外的空气。壳体9外的空气经过导风孔10进入空气过滤器6，经过空气过滤器6过滤后的空气流再经过第一送风部2吹送到第二送风部5，再由第二送风部5发散到更远范围内。如图3所示，图中的箭头线指示方向示意的是空气净化器的空气流的流动方向。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
