可选地，机头组件20沿水平方向转动，供风组件30沿竖直方向转动。这样，通过控制机头组件20沿水平方向转动和/或控制供风组件30沿竖直方向转动，来增大风扇的送风范围。
如图7至图9所示，机头组件20包括支撑架21，支撑架21可枢转地设置在支架10上；供风组件30包括电机罩31，电机罩31可枢转地设置在支撑架21上。这样，支撑架21带动 电机罩31一起相对于支架10转动，电机罩31能够相对于支撑架21单独转动，本申请通过合理地设置风扇的结构，提升风扇的使用性能。
如图9所示，电机罩31具有安装腔314和与安装腔314连通的安装缺口315，供风组件30还包括供风电机32和罩盖33，供风电机32通过安装缺口315安装在安装腔314内，罩盖33盖设在安装缺口315处。这样，供风电机32安装在电机罩31内，罩盖33盖设在安装缺口315处，用于保护供风电机32，避免异物或灰尘进入安装腔314内，影响供风电机32的正常使用。
如图8所示，罩盖33包括盖板331和与盖板331连接的环形围板332，盖板331与电机罩31连接，盖板331上开设有避让孔333，供风电机32的输出轴321由避让孔333伸出。风扇还包括叶片，叶片与供风电机32的输出轴321驱动连接，通过控制供风电机32的启动，供风电机32带动叶片转动，来实现风扇的送风。
在本申请一具体实施例中，电机罩31的靠近盖板331的端面与盖板331通过螺钉固定连接。
可选地，盖板331和环形围板332一体成型。
可选地，供风电机32通过螺钉固定在电机罩31的中心位置处，电机罩31与支撑架21以安装孔212为旋转中心铰接。
如图1至图3所示，风扇还包括网罩50，网罩50与罩盖33连接，并将叶片罩设在内。这样，能够避免叶片在转动过程中伤人，也能避免有异物在叶片的转动过程中碰撞叶片，影响风扇的正常工作。在需要对电扇进行俯仰调节时，仅需要手动摆动网罩50，从而使网罩50、叶片和供风组件30一起相对于机头组件20和支架10转动，实现风扇的俯仰调节。
如图7至图9所示，机头组件20还包括机壳22，机壳22与支撑架21连接，并罩设在支撑架21和电机罩31的外侧；机壳22具有避让开口221，环形围板332位于避让开口221处，并与机壳22的内壁间隙配合。这样，机壳22罩设在支撑架21和电机罩31的外侧，用于保护支撑架21和电机罩31，保证风扇的外观整洁美观。在供风组件30相对于机头组件20转动时，环形围板332始终与机壳22的内壁存在一定的间隙。
可选地，机壳22的轴向中心与罩盖33的轴向中心重合设置。
如图9所示，环形围板332呈喇叭状，且环形围板332形成的孔截面积沿远离盖板331的方向逐渐增大。这样，罩盖33与机壳22间隙配合的部分为圆弧设计，在进行俯仰调节过程中，运动的罩盖33始终与机壳22保持间隙配合，避免罩盖33在转动时，与机壳22之间出现干涉，出现噪音磨损等问题，有利于提升风扇的使用性能和使用寿命。
如图9至图11所示，支撑架21具有两个间隔设置的安装板211，两个安装板211上均开设有安装孔212，两个安装孔212相对设置；电机罩31包括电机罩本体311和设置在电机罩本体311两侧的两个转轴312，转轴312上开设有螺纹孔313，电机罩本体311位于两个安装 板211之间，两个转轴312分别位于两个安装孔212处；风扇还包括紧固件40，紧固件40伸入螺纹孔313内，将安装板211夹设在紧固件40与电机罩本体311之间。电机罩31通过转轴312和安装孔212可枢转地设置在支撑架21上。
如图9和图11所示，风扇还包括止转轴套80和止转外罩90，止转轴套80套设在转轴312上，止转外罩90套设在止转轴套80上，止转轴套80和止转外罩90将安装板211夹设在两者之间，紧固件40伸入螺纹孔313将止转轴套80和止转外罩90紧固连接。这样，通过紧固件40施加预紧力，使电机罩31能够相对于支撑架21停止转动，停留在需要的俯仰位置处，在需要控制风扇进行俯仰调节时，手动掰动供风组件30来实现风扇的俯仰调节。
可选地，紧固件40为螺钉。
如图7至图9所示，支撑架21还包括连接在两个安装板211之间的连接板213和与连接板213的下表面连接的支撑筒214，支架10具有装配孔11，支撑筒214可枢转地安装在装配孔11内。这样，支撑架21通过支撑筒214和装配孔11与支架10可枢转地连接。
如图7和图8所示，连接板213上开设有让位孔215，机头组件20还包括驱动件23和传动组件24，驱动件23安装在连接板213上，且驱动件23的输出端由让位孔215伸出后通过传动组件24与支撑筒214驱动连接。这样，通过驱动件23和传动组件24驱动支撑筒214相对于支架10转动，实现电扇的左右摇头。
如图7和图8所示，驱动件23为驱动电机，传动组件24包括曲柄241和连杆242，曲柄241与驱动电机的输出轴连接，曲柄241与连杆242的第一端连接，连杆242的第二端与支撑筒214驱动连接。这样，驱动电机的输出轴驱动曲柄241转动，曲柄241带动连杆242转动，连杆242带动支撑筒214转动，通过控制驱动电机的启动，来实现风扇自动地左右摇头，增大风扇的送风范围。
可选地，机壳22的底部开设有避让支撑筒214的圆孔，支撑筒214由圆孔伸出后伸入装配孔11内，机壳22通过底部的圆孔套设在支架10上，提升电扇的整体美观。
如图7和图8所示，电扇还包括轴套70，轴套70与支架10连接，并位于装配孔11处，支撑筒214穿过轴套70伸入支架10的装配孔11内。
从以上的描述中，可以看出，本发明上述的实施例实现了如下技术效果：
本申请提供的风扇在进行俯仰调节的过程中，机头组件20始终保持水平状态，这样，机头组件20在长期运动过程中不会导致驱动电机的输出轴存在较大的径向受交变应力，避免机头组件20内部齿轮的配合间隙加大，出现摇头卡顿或异响等失效情况。
此外，风扇在进行俯仰调节时，机头组件保持不动，减轻了风扇俯仰调节的部分的重量，从而有效地避免了风扇出现倾倒的问题，这样，在不需要考虑风扇容易倾倒的问题时，能够增大风扇手动俯仰调节的角度范围。
本申请提供的风扇具有结构简单、成本低、运行平稳、良好的使用性能和使用寿命的优点。
