请参照图1-3，本申请提供一种驱动组件，用于驱动扇头组件100的扇头60转动。
所述驱动组件包括：
第一驱动电机20，该第一驱动电机20和扇头60连接，第一驱动电机20驱动扇头60沿水平方向摆动；
第二驱动电机70，该第二驱动电机70与第一驱动电机20及扇头60连接，第二驱动电机70驱动扇头60和第一驱动电机20沿水平方向转动。
在本申请一实施例中，驱动组件还包括电机支架10，所述第一驱动电机20设于电机支架10，所述第三驱动电机50设于电机支架10。
在本申请一实施例中，所述扇头60与第三驱动电机50的输出轴51连接。
本申请的驱动组件的第一驱动电机20和扇头60连接，该第二驱动电机70与第一驱动电机20及扇头60连接，第一驱动电机20驱动扇头60沿水平方向摆动，同时，第二驱动电机70驱动扇头60和第一驱动电机20沿水平方向转动，使得扇头60在沿水平方向摆动时，扇头60还沿水平方向转动（即，驱动扇头60左右摆动，同时左右转动），从而增加了风扇的送风范围。
进一步地，第一驱动电机20可驱动扇头60沿水平方向摆动，第二驱动电机70驱动扇头600沿水平方向转动，使得扇头60处会产生较大的负压，从而吸入较多的空气，使得扇头60可吹出较大的风，且风速较大。因此，应用该驱动组件的风扇还具有送风距离远、风速强的优点。
该驱动组件还包括与第一驱动电机20连接的传动组件，该传动组件包括传动齿轮30，所述传动齿轮30套设于第一驱动电机20的输出轴21，所述传动齿轮30呈水平设置。
该传动组件还包括与传动齿轮30相啮合的啮合件40，所述驱动组件还包括设于电机支架10的第三驱动电机50，所述第三驱动电机50与啮合件40远离传动齿轮30的一端连接，所述扇头60与第三驱动电机50的输出轴51连接。
可以理解的，扇头60的扇叶61可围绕中心轴线A旋转；传动齿轮30可围绕中心轴线B旋转。
啮合件40，所述啮合件40凸设有与传动齿轮30相啮合的啮合部41。
本申请至少一实施例中，传动齿轮30开设有容纳孔（未标示），输出轴21伸入容纳孔中，使得第一驱动电机20工作时，可通过输出轴21带动传动齿轮30转动。
本申请至少一实施例中，传动齿轮30设有保护套31，保护套31开设有所述容纳孔，输出轴21可容纳于保护套31的容纳孔，使得保护套31可保护输出轴21，还可带动传动齿轮30转动。
本申请技术方案的驱动组件的传动齿轮30套设于第一驱动电机20的输出轴21上。当第一驱动电机20工作时，驱动传动齿轮30先沿第一方向转动，再驱动传动齿轮30沿与第一方向相反的第二方向转动，如此不断重复。由于风扇正常放置时，传动齿轮30呈水平方向设置，此时，所述第一方向可为向左，第二方向可为向右。由于传动齿轮30与啮合部41相啮合，第三驱动电机50与啮合件40远离传动齿轮30的一端连接，且扇头60与第三驱动电机50的输出轴51连接，使得传动齿轮30带动第三驱动电机50和扇头60沿水平方向摆动，如先向左摆动，再向右摆动，如此不断重复。同时，第三驱动电机50还会通过其输出轴51驱动扇头60沿环绕其中心轴线A的方向旋转，具体地，第三驱动电机50还会通过其输出轴51驱动扇头60沿环绕其中心轴线A的方向继续360°旋转。将该驱动组件应用于风扇100时，扇头60的扇叶61在沿垂直于其中心轴线A的方向的转动过程中，还会左右摆动，从而增加了风扇的送风范围。进一步地，第三驱动电机50和扇头60左右摆动，使得送出的风也左右摆动，使得送出的风更加舒适、清爽。
具体地，扇头60与第三驱动电机50先向左摆动0°＜R≤30°，再摆动至初始位置，再向右摆到0°＜R≤30°，再摆动至初始位置，如此不断重复。可选地，根据实际需求，扇头60与第三驱动电机50向左和向右均摆动到10°、20°、30°、25°、或15°等。
具体地，扇头60与第三驱动电机50先向左转动0°＜R≤180°，再转动至初始位置，再向右转到0°＜R≤180°，再转动至初始位置，如此不断重复。可选地，根据实际需求，扇头60与第三驱动电机50向左和向右均转动到180°、170°、160°、155°、或150°等。
进一步地，驱动组件可驱动扇头60围绕中心轴线A旋转，并左右摆动，使得扇头60处会产生较大的负压，从而吸入较多的空气，使得扇头60可吹出较大的风，且风速较大。因此，应用该驱动组件的风扇还具有送风距离远、风速强的优点。
所述驱动组件还包括支撑第一驱动电机20的支撑件23，所述支撑件23设于电机支架10远离扇头60的一端，所述支撑件23开设有通孔2311，所述传动齿轮30套设于输出轴21穿过通孔2311的部分。
在本申请一实施例中，第一驱动电机20通过支撑件23牢固地连接于电机支架10远离扇头60的一端。
支撑件23包括支撑板231，该支撑板231大致呈正方体结构。支撑板231的表面凸设有支撑筒233，该支撑筒233与该通孔2311连通。传动齿轮30可转动地设于支撑筒233的自由端，输出轴21依次穿过通孔2311和支撑筒233，使得传动齿轮30套设于输出轴21穿过通孔2311和支撑筒233的部分。当第一驱动电机20工作时，输出轴21转动，从而带动传动齿轮30转动。
所述啮合件40还包括与第三驱动电机50连接的底板43，底板43背向第三驱动电机50的表面设有与传动齿轮30相啮合的啮合部41。
底板43大致呈圆盘状结构。
本申请至少一实施例中，底板43固设于第三驱动电机50上。可以理解的，啮合部41凸设于底板43远离第三驱动电机50的表面。
由于第三驱动电机50与底板43固接，且扇头60与第三驱动电机50的输出轴51连接，使得第一驱动电机10可通过啮合件40驱动第三驱动电机50和扇头60不断往复地沿水平方向左右摆动，从而增大风扇的送风范围。
所述第三驱动电机50包括连接板53，连接板53的中心区域设有保护筒533，连接板53还开设有与保护筒533连通的过孔531，输出轴51穿过过孔531和保护筒533与扇头60连接。
该连接件13开设有容纳槽131，连接板53容纳于容纳槽131，以将第三驱动电机50固设于电机支架10的连接件13上。
连接板53容纳于容纳槽131，第三驱动电机50的输出轴51穿过连接板53的过孔531，使得连接板53不仅可将第三驱动电机50与电机支架10相连接，还可作为第三驱动电机50的输出轴51的支点，输出轴51可以在过孔531中转动，以保护第三驱动电机50不受磨损。同时，输出轴51穿过过孔531后与扇头60连接，以带动扇头60的扇叶61环绕中心轴线A进行360°旋转。
所述驱动组件还包括轴承55，轴承55套设于保护筒533，输出轴51穿过过孔531和保护筒533及轴承55与扇头60连接。
轴承55可作为第三驱动电机50的输出轴51的支点，输出轴51可以在轴承55中转动，以保护第三驱动电机50不受磨损。
该第二驱动电机70设于电机支架10远离扇头60的一端。
驱动组件还包括将第二驱动电机70安装于电机支架10的的安装件71。
在本申请至少一实施例中，电机支架10包括基底11、连接件13和连接条15，连接件13和连接条15分别设于基底11两端。可选地，连接条15的数量可为两个，所述两个连接条15可以间隔设置，从而形成一安装区域。
安装件71设于基底11，并容纳于连接条15之间的安装区域中，以使第二驱动电机70固设于电机支架10上。
在本申请一实施例中，安装件71还凸设有至少一安装块711。可选地，该安装块711的数量为两个，第二驱动电机70设于安装件71上，并位于两个安装块711之间。
支撑板231搭设于连接条15，以将第一驱动电机20固定连接于电机支架10上，并与第二驱动电机70相对设置。
当第二驱动电机70工作时，第二驱动电机70驱动电机支架10、第一驱动电机20、第三驱动电机50及扇头60沿平行于扇头60的中心轴线A的方向往复摆动，也就是说，第二驱动电机70驱动电机支架10、第一驱动电机20、第三驱动电机50及扇头60于水平方向左右摆动。使得扇头60在第三驱动电机50的驱动下环绕中心轴线A进行360°旋转，在第一驱动电机20的驱动下要水平方向进行左右摆动，还在第二驱动电机70的驱动下水平方向左右摆动，使得扇头60的送风范围较大。
本申请还提供一种扇头组件100，所述扇头组件100包括所述驱动组件和扇头60，扇头60包括扇叶61。
本申请一实施例中，扇叶61包括主扇叶611和千叶613，所述轮毂63固设有多个主扇叶611，相邻主扇叶611间设千叶613，所述千叶613与主扇叶611在轮毂63轴向上呈鸭式布局布置。扇头60旋转时，进风侧气流经千叶613加速形成干扰主扇叶611气流的分离涡，于主扇叶611吸力面上产生将主扇叶611根部前缘堆积的回流带走的吸力，使主扇叶611根部前缘气流变得顺畅、实际做功面积增加，因而本扇头60内流品质佳、效率高。使得扇头60的送风范围更大、送风距离更远、风速更快。
通常，相对于流经扇头60的气流，所述千叶613在轮毂轴向上的位置位于主扇叶611的上游，使扇头60内流品质更佳。
本申请实施例中所述主扇叶611和千叶613分别为前弯掠和后弯掠设计，所述千叶613采用后弯前缘和直后缘造型且该后缘具有一前掠角。其中，所述千叶613与主扇叶611呈上位鸭式布局布置在轮毂63上。需要注意的是，此处还可使所述千叶613与主扇叶611呈下位鸭式布局布置在轮毂63上，增强扇头60设计的灵活性。应当理解，所述主扇叶611还可以是后掠或直叶片设计。
由于该扇头组件100采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
参图4，述扇叶61旋转时所形成的理论气流柱的最外缘与扇叶61的旋转中心轴线A的夹角定义为风扩散角R，本申请的风扩散角R满足：0°＜R≤45°。
可选地，本申请的风扩散角R满足：5°＜R≤45°。
本申请技术方案的风扇的风扩散角为0°＜R≤45°，在此范围下，风扇可以具有较大的送风范围，吹出的风也可满足用户对舒适度的要求。
设定现有技术中扇叶的风扩散角为R0。
其中，R＜R0，表明本申请的风扇送出的风具有风速较大的优点，送风距离更远。
所述扇头组件100还包括外壳80，电机支架10设于外壳80上，所述外壳80开设有孔81，输出轴51穿过孔81与扇头60连接。
外壳80还设有卡合端83，卡合端83卡合于第三驱动电机50的外表面，将第三驱动电机50与外壳80连接。
外壳80可以增加扇头组件100的外观的美观性，同时可以防止进入扇头组件100。
所述扇头组件100还包括夹设于外壳80和扇头60之间的网罩索母90，网罩索母90开设有贯穿孔91，输出轴51穿过孔81和贯穿孔91与扇头60连接。
本申请一实施例中，网罩索母90位于外壳80的远离电机支架10的一侧。
本申请一实施例中，网罩索母90与外壳80螺纹连接，第三驱动电机50的输出轴51穿过外壳80和网罩索母90与扇头60连接。网罩索母90用于将扇头60的轮毂63限定在外壳80与网罩索母90之间，起到固定轮毂63的目的。
本申请还提供一种风扇（未图示），包括支撑组件（未图示）和上述扇头组件100，所述扇头组件100可转动地设于支撑组件。
由于该风扇采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
以上仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是在本申请的申请构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接或间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
