具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
参见图1至图5所示，根据本申请的实施例，提供了一种电器件，本实施例中的电器件尤其指立式带旋转机身结构的电器件，例如电暖器、电风扇等结构，本实施例中的电器件尤其指电暖器。本实施例中的电器件包括机身和支撑件(图中未示出)，本实施例中的立式带机身结构的电器件的机身沿重力方向或与底座垂直方向自转。安装时，将机身安装在支撑件上，正如背景技术中记载的那样，现有的电暖器安装好之后，外壳组件的底部与用于安装支撑件的结构之间具有一定间隙，受外力作用时，机身容易晃动，容易造成支撑件断裂，因此，本申请中对电暖器的结构进行了改进。
具体而言，本实施例中的电暖器还设置有防晃动机构，该防晃动机构包括外壳组件10、底座组件20以及摩擦支撑组件30，其中，外壳组件10设置在底座组件20上；摩擦支撑组件30包括第一摩擦件31、第二摩擦件32以及滚动支撑机构33，第一摩擦件31设置在外壳组件10的底部，第二摩擦件32设置在底座组件20的顶部，滚动支撑机构33设置在第一摩擦件31和第二摩擦件32之间，且滚动支撑机构33与第一摩擦件31和第二摩擦件32之间均为多点接触或线接触或面接触。
安装时，将支撑件安装在防晃动机构上，然后将机身安装在外壳组件10上，当机身或外壳组件受外力作用时，机身或外壳组件传递给摩擦支撑组件30，由于滚动支撑机构33与第一摩擦件31和第二摩擦件32之间均为多点接触或线接触或面接触，外壳组件或机身受力后作用力直接施加在底座组件20上，不会使外壳组件或机身产生过大的晃动，进而对支撑件进行保护，提高电暖器的结构强度和稳定性。
可见，本实施例中通过设置防晃动机构，能够有效防止机身晃动，便于对支撑件进行保护。
为了便于安装，本实施例中的外壳组件10上设置第一轴孔13，底座组件20上设置有与第一轴孔13对应的第二轴孔21，实际组装时，通过第一轴孔13和第二轴孔21的作用，便于将转轴类支撑件安装在外壳组件10和底座组件20上，机身安装在外壳组件10上并与转轴驱动连接，进而便于对机身进行支撑。
再次参见图1至图5所示，本实施例中的外壳组件10的底部设置有与第一轴孔13同轴设置的第一环形凹槽14，第一摩擦件31为安装在第一环形凹槽14内的第一摩擦环，结构简单，便于安装。当然，在本申请的其他实施例中，还可以将第一摩擦件31设置其他形状的摩擦块，只要是在本申请的构思下的其他变形方式，均在本申请的保护范围之内。
为了防止第一摩擦环在外壳组件10的底部转动，本实施例中的第一摩擦环和第一环形凹槽14两者之一上设置有第一防转凸块311，两者另一上设置有与第一防转凸块311相适配的第一凹陷部15。
同样地，底座组件20的顶部设置有与第二轴孔21同轴设置的第二环形凹槽22，第二摩擦件32为安装在第二环形凹槽22内的第二摩擦环，结构简单，便于实现。
第二摩擦环和第二环形凹槽22两者之一上设置有第二防转凸块321，两者另一上设置有与第二防转凸块321相适配的第二凹陷部23，通过第二防转凸块321和第二凹陷部23的作用，便于防止第二摩擦环在底座组件20上转动。
滚动支撑机构33包括支撑架331和钢珠332，多个钢珠332沿支撑架331的周向安装在支撑架331上，各钢珠332与第一摩擦件31和第二摩擦件32点接触，通过多个钢珠332分别与第一摩擦件31和第二摩擦件32形成多点接触，进而便于安装在外壳组件10上的机身进行支撑，防止机身受外力作用而产生晃动，与此同时，还能够有效防止机身转动过程中发生过大的噪音。本申请使得钢珠332处于支撑架331的上下两端之间，其下端与第二摩擦件32接触，支撑架331固定在底座组件20上；钢珠332的上端面与第一摩擦件31的底面接触，使得钢珠332对机身有支撑作用，便于防止机身晃动。
当然，在本申请的其他实施例中，还可以将钢珠332设置成滚动柱，使得滚动支撑机构33与第一摩擦件31和第二摩擦件32形成线接触，或者在第一摩擦件31和第二摩擦件32上设置球面槽，将钢珠332安装在球面槽内，使得钢珠332与第一摩擦件31和第二摩擦件32实现面接触，只要是在本申请的构思下的其他变形方式，均在本申请的保护范围之内。
实际安装时，支撑架331通过锁定组件安装在外壳组件10或者底座组件20上。优选地，本实施例中的锁定组件为卡扣3311或者螺钉或者销钉，结构简单，便于组装。
优选地，在本申请的一种优选的实施例中，将锁定组件为卡扣3311，对应地，在底座组件20上设置有与卡扣3311对应的卡孔24，卡扣3311穿过第二摩擦件32与卡孔24配合固定，使卡扣3311穿过第二摩擦件32固定在卡孔24内，能够在支撑架331固定的同时将第二摩擦件32固定在底座组件20上。
本实施中的外壳组件10包括前壳部11和与前壳部11扣合设置的后壳部12，通过外壳组件的作用，便于对机身进行安装，且便于将外壳组件安装在转轴上。本实施例中的前壳部11和后壳部12固定在一起组成外壳组件10，外壳组件10下部中间部分设置有第一轴孔13，第一轴孔13的四周围边；在围边第一轴孔13外侧安装第一摩擦件31，使第一摩擦件31固定在外壳组件10上，且轴心保持与外壳组件10的第一轴孔13同心。
优选地，本实施例中的第一摩擦件31和第二摩擦件32均采用自润滑材料制作而成。当人为推动机身或外壳组件时，外壳组件10底部会给钢珠332一个作用力，钢珠332受力后对底座组件20产生作用力，因钢珠332上下端面与第一摩擦件31和第二摩擦件32均为接触状态，因此机身或外壳组件受力后作用力直接施加在底座组件20，不会使机身或外壳组件产生过大的晃动。当将防晃动机构应用于具有摇头功能的暖风机电暖器上时，在摇头转动过程中，机身带动第一摩擦件31一起转动，底座组件20静止不动，此时钢珠332还可以起到支撑机身转动的功能。
可见，本申请中的防晃动机构容易实现，零件较少，能够解决机身受外力晃动大的问题，且该方案可靠性高。
从以上的描述中，可以看出，本申请上述的实施例实现了如下技术效果：本申请通过在机身和支撑件之间增加防晃动机构，当人手推动整机时，机身晃动小，保持平稳，同时保证支撑件不易被损坏，增加使用寿命，可靠性高，运行稳定。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
