具体实施方式
下面将结合本实用新型的实施例的附图，对本实用新型的技术方案进行说明。
本实用新型的一个实施例的风扇灯的开合结构，其包括主体结构1以及复位结构2。
主体结构1包括基座11以及与基座11铰接的离心件12。
通常，基座11固定设置(比如通过镶嵌实现固定)有轴承119，离心件12的内圈与轴承119固定连接(比如通过螺栓以及复位连接件22夹持固定)；以保证离心件12开合比较顺畅。
通常，旋转装置8设置安装件81，安装件81用于将旋转装置8安装到所需的位置，比如房间顶壁等处。
复位结构2包括弹性件21。
弹性件21分别与离心件12、基座11连接，使离心件12有闭合的趋势。
工作原理为：离心件12表面与垂直于旋转装置8的旋转轴心的平面之间、设置有非零的夹角，旋转装置8驱动基座11基座旋转、使离心件12依靠离心力展开(此时为展开状态)并旋转、推动空气实现吹风功能。旋转装置8停止旋转时，弹性件21使离心件12复位为闭合状态。
由上述可以看出，能够使离心件12顺利地展开、闭合。
优选的，离心件12为两个以上，主体结构1还包括与基座11铰接的联动圈13，离心件12与联动圈13啮合。通常，离心件12、联动圈13均设置有联动齿139，以实现相互啮合。能够实现离心件12同步开合，且展开状态时的离心件12的展开同步(即展开状态时各离心件12绕旋转装置8的旋转轴心旋转对称)。
优选的，联动圈13开始有俯视时为环扇形的限位孔141，基座11固定设置(螺纹连接)有限位件14，限位孔141插入限位孔141且顶端与联动圈13相抵，从而使联动圈13与基座11铰接。通常，限位孔141为两个以上且绕旋转装置8的旋转轴心均布。实现限位功能的同时、能够简化联动圈13与基座11铰接的结构，有利于降低成本。
进一步的，复位结构2还包括复位连接件22，复位连接件22与离心件12固定连接(通常与离心件12的铰接座121固定连接)，离心件12、复位连接件22分别位于基座11的两面，弹性件21分别与复位连接件22、基座11连接，从而使弹性件21分别与离心件12、基座11连接。通常，离心件12位于基座11的顶端面、离心件12位于基座11的底端面，但反之也可以。组装弹性件21时、弹性件21不会被离心件12阻挡，便于弹性件21的组装；同时，离心件12开合的过程中离心件12不会被离心件12阻挡干涉，能够提高可靠性。
进一步的，复位连接件22的两端分别为复位端221、连接端222，离心件12开设有连接槽123，连接端222设置有连接耳223，连接耳223插入连接槽123。便于弹性件21以及复位连接件22的组装。
优选的，弹性件21为直线弹性件(比如为弹簧、气弹簧等、提供的弹力的方向始终沿一直线)，闭合状态时离心件12与基座11铰接轴心、弹性件21与基座11的铰接轴心之间的连线，与弹性件21的弹力方向的夹角为复位力矩角α，复位力矩角α为大于等于零度且小于等于十度，优选为六度。旋转装置8启动时开始阶段的旋转速度较慢；复位力矩角α为大于等于零度且小于等于十度，弹性件21提供的力矩(弹力大小固定、到弹性件21的弹力方向的距离较小)较小，从而离心件12提供的离心力产生的力矩 能够尽快克服弹性件21提供的力矩，从而能够使离心件12较快速地展开。
作为一种实施方式，弹性件21为提供拉力的弹簧、且两端分别与复位端221、基座11挂钩连接。提供拉力的弹性件21不会弯曲，便于弹性件21的组装。
