具体实施方式
下面结合附图和实施例对本发明做进一步说明。
请参照图1，本摇头伸缩折叠风扇包括底座10、伸缩式支撑杆20、风扇本体40和第一电机30。其中，所述第一电机30安装在所述支撑杆20的顶端，所述风扇本体40安装在所述第一电机30，通过第一电机30驱动风扇本体40左右摆动实现摇头。在所述底座10的顶部设有第一收纳腔11，所述支撑杆20的底端设有枢轴21，底座10上对应该枢轴21设有枢孔14(见图4)，枢轴21和枢孔14配合将支撑杆20安装在底座10上。
使用状态下，支撑杆20与底座10的上端相垂直，如图8、图9所示。在使用状态下，将支撑杆20绕枢轴21转动90度后，支撑杆20即被收纳至所述第一收纳腔11中(见图3)，风扇本体40叠置在底座10的上端(如图2所示)，使风扇进入折叠状态。
在所述支撑杆20和所述底座10之间设有锁紧机构70，用于将所述支撑杆20锁定在收纳状态或使用状态。其中，锁紧机构70采用自动锁紧机构，如图4所示，所述自动锁紧机构70包括弹性波珠71和凹陷卡位72。以收纳状态为例，如图4所示，支撑杆20在使用状态 或收纳状态时，弹性波珠71陷入凹陷卡位72中，凹陷卡位72对弹性波珠71形成阻挡，将支撑杆20锁定在当前状态，当给支撑杆20施加绕枢轴的旋转外力，克服凹陷卡位72对弹性波珠71的阻挡力后，支撑杆20从当前状态自动解锁，可绕枢轴21转动，当支撑杆20转动至收纳状态或使用状态后，受波珠弹簧712的弹力作用，弹性波珠71陷入凹陷卡位72中，从而自动将支撑杆20锁定在当前状态。凹陷卡位72优选凹球面结构。采用自动锁紧机构70，风扇折叠或展开后自动锁定在当前状态，不需要额外的锁定操作，使用更方便。
参照图4，本实施例中，所述凹陷卡位72设于所述底座10内部的立板15上、且与所述枢轴21的端部相对，所述弹性波珠71设于所述枢轴21的端部。作为另一种实施方式，与上述相反，即：可以将所述凹陷卡位72设于所述枢轴21的端部，所述弹性波珠71设于所述底座10内部的立板15上、且与所述枢轴21的端部相对。
参照图4，本实施例中，对应枢轴21的每一端，分别设有凹陷卡位72，锁紧后稳定性更好。每一端包括两个所述凹陷卡位72，两个所述凹陷卡位72分别对应支撑杆20的使用状态和收纳状态，两个所述凹陷卡位72相对所述枢轴21的轴线呈90度夹角。这种结构，对应枢轴21的每一端，只需一个弹性波珠71，由于相比弹性波珠71，卡位72的结构及加工成本更低，因此优选该实施方式。作为另一种实施方式，与上述相反，即：对应枢轴21的每一端，分别设置两个所述弹性波珠71，两个所述弹性波珠71分别对应支撑杆20的使用状态和收纳状态，两个所述弹性波珠71相对所述枢轴21的轴线呈90度夹角。
请参照图4、图5，所述弹性波珠71包括波珠本体711和波珠弹簧712，所述波珠本体711和所述波珠弹簧712安装于一固定座73， 所述固定座73通过螺钉75固定在所述枢轴21的端部。枢轴21上设有杆套23，支撑杆20的底端插设在杆套23内，通过螺钉75固定。
伸缩式支撑杆20采用多节拉杆，收缩状态下，支撑杆20的长度能够收纳至第一收纳腔11中；伸开状态下，能够将风扇本体40支撑在合适的高度，例如图8中的状态或图9中的状态。
进一步所述摇头伸缩折叠风扇还具有喷雾机构60，所述喷雾机构60安装于所述底座10内，所述喷雾机构60的喷雾孔(见图1)朝向所述风扇本体40的出风端。通过控制开关，可以控制喷雾机构60喷水雾，风扇本体40吹出的风将水雾吹散在环境中，使人感觉更凉爽。
如图6所示，一实施例喷雾机构60包括水箱61，水箱61的顶部设有雾化头组件64和注水口62，注水口62配有胶塞63。该喷雾机构60为一个独立结构，可以整体从底座10拆卸，方便维修。雾化头组件64包括雾化片642、雾化片盖641、吸水海棉棒643和吸水海棉棒弹簧644。
参照图1、图6，所述喷雾机构60的顶部设有注水口62，所述底座10的顶部对应所述喷雾机构60设有盖板12，所述盖板12对应所述喷雾孔设有过孔13。正常使用时，盖板12将注水孔遮蔽，底座10表面整洁美观。需要向水箱61补水时，打开盖板12，取下注水口62的胶塞63即可，非常便捷。
请参照图1、图7，所述摇头伸缩折叠风扇进一步还具有照明机构50，所述风扇本体40的背部的中心设有第二收纳腔(未图示)，所述照明机构50通过软管51安装于所述风扇本体40，需要照明时，将照明机构50从第二收纳腔中拉出，调节软管51的角度，使照明机构50的出光面朝向需要的位置，例如图9中的位置；不需要照明时，将照明机构50收纳在第二收纳腔中，如图1所示，不影响风扇本体40 的外观。这样，当在户外等没有照明设备的场所，能够方便地提供照明。照明机构50优选板形结构的LED灯。
参照图7，进一步在所述风扇本体40的背板设有线槽44，所述照明机构50的控制及供电线缆置于所述线槽44中、并通过所述支撑杆20的内部后与所述底座10内的控制板相连。线缆通过压线板43封闭在线槽44中，不会外露。
所述风扇本体40包括面罩41、扇叶42、背壳45和驱动扇叶42的第二电机，所述第二电机为外转子电机，外转子电机的转子部分固定在扇叶42中心，外转子电机的定子部分固定在背壳45的中心。采用外转子电机，电机运行中产生的热量可通过转子能更好地外散，可以降低风扇长时间运行时电机发热引起的故障率。
进一步参照图1，所述第一电机30和所述支撑杆20的顶端之间还设有连杆22，所述连杆22和所述支撑杆20的顶端枢接。这样，当支撑杆20收纳至第一收纳腔11后，可以将风扇本体40绕支撑杆20的顶端转动90度，可以进一步减小底座10的占地面积，并且，使得在折叠状态下，风扇本体40的背面与底座10的顶部贴合，将照明机构50夹在风扇本体40和底座10之间，从外部看不到照明机构50，外形美观，而且在震动等外力作用下照明机构50不会脱出，安全性好。
请参照图10、图11，在本实施例中，风扇本体40通过轴承34支撑于所述连杆22，所述第一电机30与所述风扇本体40卡配、且其转轴贯穿所述轴承34与所述连杆22固定。具体地，轴承34的外圈与风扇本体40的背壳45卡配，轴承34的内圈与连杆22紧配，以此将风扇本体40通过轴承34支撑于所述连杆22、可绕轴承34的轴线转动，在第一电机30的转轴固装轴套31，轴套31通过转承固定件 33与轴承34的内圈紧配，轴承固定件33通过固定螺栓32与连杆22固连。工作时，控制板控制第一电机30正反交替工作，驱动风扇本体40绕所述轴承34的轴线摆动。
请参照图10、图11，在本实施例中，所述支撑杆20的顶端固定有安装环26，所述连杆22成型有凸轮部24，所述凸轮部24通过偏心轴27支撑在所述安装环26中、且在所述凸轮部24和所述安装环26之间设有胶圈25，通过所述凸轮部24和所述安装环26配合，将连杆22和支撑杆20顶端枢接，凸轮部24绕偏心轴27转动时，大径点对应安装环26的内壁的位置发生变化，以此可以实现连杆22绕支撑杆20顶端的旋转定位。
进一步在所述底座10还设有供电电池80(见图3)以及给所述供电电池80充电的充电接口，可以在户外等没有外接电源的场合给风扇、照明机构50、喷雾机构60供电，实现吹风、照明和喷雾功能。
上述第一电机30优选步进电机。
由上可见，本风扇集吹风、喷雾、照明功能于一体，至少具有以下有益效果：风扇本体40和底座10可折叠，便于收纳、携带和保存；其风扇本体40可摇头，吹风区域大；采用自动锁紧机构70，不需要手动进行锁紧操作，使用方便；自带电池，可适于户外等无电源场合使用；采用可拆卸喷雾机构60，维修方便。
上述通过具体实施例对本发明进行了详细的说明，这些详细的说明仅仅限于帮助本领域技术人员理解本发明的内容，并不能理解为对本发明保护范围的限制。本领域技术人员在本发明构思下对上述方案进行的各种润饰、等效变换等均应包含在本发明的保护范围内。
