如图1所示，一种立体旋摆结构，包括第一旋转组件10和第二旋转组件20；所述第一旋转组件10包括第一转轴12和第一电机11，所述第一转轴12上设有物件30，所述第一电机11驱动所述第一转轴12旋转，所述物件13随之旋转；所述第二旋转组件20包括第二转轴22和驱动机构21；所述第一旋转组件10设置在所述第二转轴22上，所述驱动机构21驱动所述第二转轴22旋转，带动所述第一旋转组件10旋转，所述物件30随之旋转。
应理解，所述第一转轴12的轴心线和所述第二转轴22的轴心线可以是在同一个平面上的相交直线，也可以是不同平面上的直线。不管二者是同面线，还是异面线，二者之间的交角记为β，且β≠0、90°、180°。换而言之，所述第一转轴12的轴心线和所述第二转轴22的轴心线不重合，不平行。当二者平行、重合或垂直时，不能实现旋摆的效果。
应理解，所述第一旋转组件10设置在所述第二转轴22上，其可以通过一中间连接件实现。该中间连接件设置在所述第二转轴上，且能够绕所述第二转轴旋转，所述第一旋转组件10安装在该连接件，随该中间连接件和第二转轴同步旋转即可。
在本实用新型的较佳实施例中，所述中间连接件设置为一壳体40。所述壳体40固定设置在所述第二旋转轴上22，随所述第二转轴22同步旋转；所述第一电机11固定设置在所述壳体40上，位于所述壳体40内部或外部；所述第一转轴12和所述物件30容置在所述壳体40内。

所述第一转轴12和所述第二转轴22之间的夹角β可以在0～90°内任意选取。较佳地，10°<β<80°；优选地，30°<β<60°。最优地，β为45°。
应理解，所述第一转轴12和所述第二转轴22的轴心线可以设置在不同一平面内，也能实现本实用新型所述的立体旋摆效果。然而，为了使风扇结构稳固，或寻求结构或视觉上的和谐，在最佳的实施例中，所述第一转轴12和所述第二转轴22的轴心线设置在同一平面内，且二者均过球心。
以如图2所示的状态为所述立体旋摆结构的初始状态，所述壳体40上的切面41，朝向右方，垂直水平面。
启动所述第一旋转组件10和第二旋转组件20。所述第一电机11驱动所述第一转轴12和扇叶旋转。应理解，所述扇叶的旋转在垂直所述第一转轴12的面上。此时，所述驱动机构21驱动所述第二转轴22旋转，带动所述壳体40同步旋转。所述第一旋转组件10也随着所述壳体40同步旋转。
当所述第二转轴22逆时针旋转90°时，则所述壳体40也逆时针旋转90°到如图3所示的状态，此时，所述壳体40上的切面41绕所述第二转轴22的轴心延长线逆时针旋转90°，朝向右后方，且倾斜于水平面。
当所述第二转轴22逆时针旋转180°时，则所述壳体40也逆时针旋转180°到如图4所示的状态。此时，所述壳体40的切面41绕所述第二转轴22的轴心延长线逆时针旋转180°，朝向上方，与水平面平行。
当所述第二转轴22逆时针旋转270°时，则所述壳体40也逆时针旋转270° 到如图5所示的状态。此时，所述壳体40上的切面41绕所述第二转轴22的轴心延长线逆时针旋转270°，朝向右前方，且倾斜于水平面。
当所述第二转轴22逆时针旋转360°时，则所述壳体40也逆时针旋转360°回到如图2所示的状态。此时，所述壳体13的切面绕所述第二转轴22的轴心延长线逆时针旋转360°，朝向右方，回到垂直于水平面的状态。
应理解，所述第二转轴22的轴心的延长线与所述壳体40的切面41相交，在本实用新型较佳的实施例中，所述第二转轴22的轴心的延长线与所述壳体40的切面41的交角α为45°。
应理解，所述壳体40的切面41与所述第二转轴22的轴心的延长线的夹角α并不仅仅限定为45°。实际上，所述夹角α的取值范围可以是0<α<180°，且α≠0、90°、180°。这是因为，当α为90°时，所述切面41绕所述第二转轴22的轴心的延长线旋转，其旋转轨迹聚集在同一平面上，不能产生如上所示的翻转或摆动效果。当α为0或180°时，所述第二转轴22的轴心的延长线在所述切面41上，所述切面41绕所述第二转轴22的轴心的延长线旋转，也不能产生如上所示的翻转或摆动效果。而当0<α<90°时，如图2-图5所示，所述第二转轴22的轴心的延长线经过所述切面41内时，所述切面41绕所述第二转轴22的轴心的延长线旋转呈现较佳的翻转的视觉效果，当α为45°时，则呈现最佳的翻转视觉效果。
另外，所述壳体40的切面41可以为平面、弧形面或不规则面。如图6所示，当切面41’为弧形面时，所述壳体40的切面41’与所述第二转轴22的轴心的延长线具有一交点，过该交点做所述弧形面的切线，所述第二转轴22的轴心的延长线与该切线的夹角α应该满足的取值范围是0<α<180°，且α≠0、90°、180°。
较佳地，所述立体旋摆结构中，所述第二旋转组件20包括底座50。所述底座50上设有所述安装面51。应理解，所述安装面51与水平面之间的夹角取值范围应为0～90°。较佳地，为45°。
较佳地，参照图1，所述底座50还具有圆台形基座53，该基座上设有弧形面52，所述弧形面52和所述安装面51与所述基座53围成空腔。所述驱动机构21设置在所述空腔内。这样的设置使得所述立体摆头机构能够方便地安装于墙角类结构中，而不会在旋摆过程中遭遇空间阻碍。
参照图7，所述驱动机构21包括：设于所述底座50内的第二电机211，套于所述第二电机21主动齿轮212和套于所述第二转轴212上的从动齿轮213；所述主动齿轮212和所述从动齿轮213相互啮合。所述第二旋转轴22设置在所述从动齿轮213上。
较佳地，所述底座50上设有提手54，所述提手54设置在所述弧形面52上。
应理解，所述立体旋摆结构可以适用于取暖电风扇，舞台闪光灯等需要立体旋摆的结构中。因此，本实用新型还包括一种具有上述立体旋摆结构的风扇、风扇取暖器或闪光灯等。
以上内容是结合具体的优选实施方式对本实用新型所作的进一步详细说明，不能认定本实用新型的具体实施只局限于这些说明。对于本实用新型所属技术领域的普通技术人员来说，在不脱离本实用新型构思的前提下，其架构形式能够灵活多变，可以派生系列产品。只是做出若干简单推演或替换，都应当视为属于本实用新型由所提交的权利要求书确定的专利保护范围。
