另外，本申请各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本申请要求的保护范围之内。
本申请提出一种摇头机构，其可解决现有摇头机构摇头不顺畅、整体晃动的问题。
请参照图1、图2和图7，摇头机构包括底座1、传动组件（未标示）、与底座1连接的电机支架2以及设于电机支架2上的驱动电机3，传动组件的第一端与驱动电机3连接，传动组件的第二端与底座1连接，传动组件能够带动电机支架2相对于底座1往复运动，底座1上设有环形凹槽11，电机支架2上设有与环形凹槽11相适配的环形筋21，环形筋21置于环形凹槽11内。
本申请的一实施例中，环形凹槽11较深，以便在环形凹槽11内放置润滑油，保证摇头的顺畅，环形筋21的塑形变形程度小，环形凹槽11与环形筋21的配合，使底座与电机支架的连接更加稳固，从而增加摇头机构的刚度，避免出现晃动现象。
进一步地，请参照图2和图7，环形凹槽11的中心位置设有立轴12，电机支架2上设有套筒22，套筒22套在立轴12上且与立轴12间隙配合。套筒22套在立轴12上且与立轴12间隙配合，能够增加摇头机构的稳固程度，减少整机晃动。本申请的一实施例中，立轴12为圆锥形结构，立轴12的大端靠近环形凹槽11，立轴12的小端远离环形凹槽11，同样，套筒22也为圆锥形结构，使套筒22底端的受力面积更大，从而进一步增加摇头机构的刚度，减少整机晃动。
另外，请参照图2、图4和图5，底座1上设有弧形的限位腔16和通道13，通道13位于限位腔16的顶端且相互连通，限位腔16设置于环形凹槽11与立轴12之间，限位腔16的一端连接有进出孔14，电机支架2上设有连接杆23，连接杆23远离电机支架2的一端设有卡扣24，卡扣24能够进入进出孔14并转入到限位腔16中，限位腔16的顶壁限制卡扣24从限位腔16中脱离。
在安装电机支架2时，先将卡扣24放入进出孔14中并旋转电机支架2，则卡扣24转入限位腔16中，连接杆23转入通道13中，然后将驱动电机3与传动组件装好，装配完成后摇头机构的结构如图3和图6所示，摇头机构的整个安装过程方便快捷，提高了装配效率。驱动电机3和传动组件安装好后，能够限制电机支架2的运动轨迹，使卡扣24无法运动到进出孔14的位置。卡扣24卡在限位腔16中，能够防止电机支架2从底座1上脱落，同时卡扣24对电机支架2有拉紧作用，能够防止摇头机构整机晃动。
其中，请参照图4和图5，卡扣24远离立轴12的一端与限位腔16的顶壁的间距为h，卡扣24靠近立轴12的一端与限位腔16的顶壁的间距为H，h小于H。在电机支架2往复运动的过程中，卡扣24的远离立轴12的一端先与限位腔16的顶壁接触，卡扣24的远离立轴12的一端与限位腔16的13顶壁之间不断磨损，当磨损达到一定程度后，卡扣24靠近立轴12的一端再与限位腔16的顶壁接触，卡扣24继续卡紧底座1且拉紧电机支架2，能够进一步提高摇头机构的品质，避免因卡扣24磨损导致的整机晃动。
进一步地，请参照图7和图8，驱动电机3的两侧相对设有安装板，安装板上设有螺钉孔31以及定位孔32，电机支架2上设有与螺钉孔31相匹配的螺钉柱25以及与定位孔32相匹配的定位柱26，驱动电机3与电机支架2通过安装于螺钉孔31与螺钉柱25上的螺钉（未标示）固定。在安装驱动电机3时，先将螺钉孔31、定位孔32对准螺钉柱25和定位柱26安装，再将螺钉安装于螺钉孔31与螺钉柱25上。驱动电机3的两侧相对设有安装板，使驱动电机3与电机支架2之间的连接更加稳固；在电机支架2上设置螺钉柱25与定位柱26，通过螺钉柱25和螺钉孔31的配合固定，使驱动电机3和电机支架2的安装过程方便快捷，加快了装配效率，通过定位柱26和定位孔32的配合来定位和固定，可以减少螺钉的使用量，从而减少摇头机构的零件数量，提高生产效率。
另外，请参照图2和图7，电机支架2上设有弧形的限位槽27，底座1上设有安装柱15，安装柱15穿过限位槽27与传动组件的第二端连接。摇头机构运行时，驱动电机3驱动传动组件往复运动，传动组件作用于安装柱15上，进而推动电机支架2相对于底座1往复运动。
进一步地，请参照图1和图8，传动组件包括曲柄4以及连杆5，连杆5的第一端通过曲柄4与驱动电机3连接，连杆5的第二端与安装柱15连接。在一实施例中，驱动电机3上设有电机轴33，曲柄4的第一端设有与电机轴33连接的轴孔41，曲柄的第二端设有安装轴42，连杆5的第一端设有与安装轴42连接的安装孔51。驱动电机提供驱动力，带动曲柄4和连杆5移动，连杆5上的力作用于安装柱15上且带动电机支架2相对于底座1往复运动，从而实现摇头动作。
本申请还提供一种暖风机（未图示），该暖风机上设有如上文所述的摇头机构。暖风机上的摇头机构中环形凹槽11与环形筋21的配合，立轴12与套筒22的配合，卡扣24与限位腔16配合，使整个摇头机构摇头顺畅，避免摇头机构晃动现象的出现。
