本申请提供的风扇100，包括立柱组件102和风扇头104，风扇头104和立柱组件102通过铰链组件106和支撑结构108相连接，其中，铰链组件106的第一连接件1060和第二连接件1061相铰接，也就是第一连接件1060与第二连接件1061可实现相对转动，风扇头104适于绕支撑结构108转动，且风扇头104绕支撑结构108转动所围绕的轴线，与第一连接件1060和第二连接件1061之间转动所围绕的轴线相重合，从而使得风扇头104能够围绕第一连接件1060和第二连接件1061之间转动所围绕的轴线相转动，也即使得风扇头104围绕立柱组件102转动，进而实现风扇头104的出风角度的调节，同时，支撑结构108连接风扇头104和立柱组件102，提高了风扇头104与立柱组件102的连接的可靠性，同时也使得风扇100的外形更加美观，提升用户使用体验。
具体地，铰链组件106包括相铰接的第一连接件1060和第二连接件1061，第一连接件1060和第二连接件1061分别连接风扇头104和立柱组件102使得风扇头104可围绕立柱组件102转动，同时，风扇头104和立柱组件102还通过支撑结构108相连接，一方面，风扇头104绕支撑结构108转动所围绕的轴 线，与第一连接件1060和第二连接件1061之间转动所围绕的轴线相重合，使得风扇头104和立柱组件102在铰链组件106和支撑结构108这两个结构的连接下仍然可实现转动，另一方面，支撑结构108连接风扇头104和立柱组件102，使得在铰链组件106失效时，还可通过支撑结构108连接风扇头104和立柱组件102，避免风扇头104掉落，提高了风扇头104和立柱组件102之间的连接强度，提高了风扇100的可靠性，同时，也可在风扇头104调节到某一角度时，通过支撑结构108支撑风扇头104，保证了风扇头104的可靠性。
具体地，支撑结构108可呈圆环形，从而支撑结构108的圆心与第一连接件1060和第二连接件1061之间相对转动所围绕的轴线相重合。

具体地，由于风扇头104绕支撑结构108转动时所围绕的轴线与第一连接件1060和第二连接件1061转动时所围绕的轴线相重合，因此风扇头104绕支撑结构108转动时所围绕的轴线也与立柱组件102的长度方向相垂直。

实施例四：
如图2所示，根据本申请的一个实施例，包括上述实施例限定的特征，以及进一步地：铰链组件106还包括：转轴1062，第一连接件1060和第二连接件1061设置在转轴1062上，第二连接件1061适于绕转轴1062转动，其中，沿转轴1062的轴线方向，第二连接件1061设置在第一连接件1060的一侧；调节件，调节件与转轴1062相连接，调节件适于沿转轴1062的轴线方向挤压第二连接件1061。

具体地，调节件沿转轴1062的轴线方向挤压第二连接件1061，且对第二连接件1061的轴向压力的大小可被调节。第二连接件1061受到的轴向压力越大，第二连接件1061转动时所受到的阻力就越大，进而使其能够绕转轴1062转动所需要的力就越大，因此可通过调节件调节第二连接件1061转动所需要 的力的大小，同时，通过调节第二连接件1061受到的轴向压力，可调节第二连接件1061与相邻零部件之间的摩擦力，也即第二连接件1061受到的轴向压力越大，其与相邻结构之间的摩擦力就越大，当该摩擦力能够与第二连接件1061所受到的能够使其转动的力相抵时，可使得第二连接件1061固定在指定位置，进而使得与第二连接件1061相连接的部件固定在指定位置而不会随意转动，提高了铰链组件106的可靠性。可以理解的是，第二连接件1061转动时所受到的阻力包括第二连接件1061和与第二连接件1061轴向相邻的零部件之间产生的摩擦力。
具体地，第一连接件1060和第二连接件1061能够依次沿重力方向套设在转轴1062上，装配方便，且第一连接件1060和第二连接件1061之间沿转轴1062的轴向的距离可随意调节，提高了铰链组件106的通用性。

在该实施例中，调节件还包括阻尼件1064，阻尼件1064与转轴1062相连接，阻尼件1064能够增加第二连接件1061转动所受到的阻力，从而使得第二连接件1061转动时产生的摩擦力增加、第二连接件1061转动所需要的力也会增加，进而提高了铰链组件106的稳定性。其中，第一连接件1060与旋紧件1063之间、第二连接件1061与第一连接件1060之间均可选择性地设有阻尼件1064。
具体地，第二连接件1061转动时所需要的力的大小可通过增加或减少阻尼件1064来调节。比如，可在旋紧件1063旋在转轴1062的同一位置时通过增加阻尼件1064来增加第二连接件1061转动时所受到的阻力，从而使得第二连接件1061转动所需要的力增加，也就是第二接件若需要转动则需要施加更大的力，当第二连接件1061转动所受到的阻力大于或等于其他结构或人对第二连接件1061施加的力时，可使铰链组件106保持当前状态，也即保持第二连接件1061保持不动，提高了铰链组件106的稳定性。
具体地，第二连接件1061上可连接除铰链组件106之外的其他结构，其他结构包括风扇100的风扇头104或风扇100的立柱组件102，其他结构可沿第二连接件1061的转动方向对第二连接件1061施加力，当第二连接件1061转动所受到的阻力大于或等于其他结构对第二连接件1061施加的力时，可使铰链组件106及安装在第二连接件1061上的其他结构保持当前状态，从而提高了第二连接件1061及连接在第二连接件1061上的其他结构的稳定性。
进一步地，阻尼件1064为弹性垫，进而可调节第二连接件1061转动所需要的力。
进一步地，调节件还包括：垫片1065，与转轴1062相连接，第二连接件1061与限位结构之间设有垫片1065，和/或第一连接件1060与第二连接件1061之间设有垫片1065，和/或第一连接件1060与所旋紧件1063之间 设有垫片1065。

具体地，沿转轴1062的轴向，垫片1065两端与其他结构相抵，也就是垫片1065可挤压两侧的结构，进而可增加垫片1065两侧的结构转动所需要的力，提高了铰链组件106的稳定性。

具体地，转轴1062与铰链组件106上除了第二连接件1061及旋紧件1063外的其他结构相连接的部分均可对应设有限位面，且除了第二连接件1061及旋紧件1063外的其他结构与转轴1062相连接的安装孔部分的形状也与转轴1062相适配，进而防止其他结构转动，提高结构的可靠性。
进一步地，限位面的数量至少为两个，沿转轴1062的轴线的周向，至少两个限位面相对设置。
