本申请提出一种叶片调节机构100。
参照图1至图4，本申请技术方案提出的叶片调节机构100应用于空气循环器200，所述空气循环器200包括外壳210，所述外壳210形成有出风口211，该出风口211具有进风侧和出风侧，所述叶片调节机构100包括：
固定支架10，所述固定支架10与所述外壳210固定连接；
至少两导风组件30，两所述导风组件30相互间隔设置，并部分伸入所述出风口211，所述导风组件30具有相对设置的两侧边，所述导风组件30的位于出风侧的一侧边与所述固定支架10转动连接；
至少两第一连杆50，一所述第一连杆50的一端与一所述导风组件30位于进风侧的一侧边转动连接，且两所述第一连杆50延其长度方向延长线相交；
第二连杆70，每一所述第一连杆50背离所述导风组件30的端部均与所述第二连杆70固定连接；
驱动所述第二连杆70相对所述导风组件30靠近运动或远离运动，使所述第一连杆50带动所述导风组件30绕固定支架10转动，所述导风组件30伸入出风口211的部分相对出风口211张开或聚拢，以使所述出风口211发散吹风或集中吹风。
本申请的技术方案通过在外壳210设置出风口211，以及在外壳210设置固定支架10、导风组件30、第一连杆50和第二连杆70，将导风组件30位于出风侧的一侧边与固定支架10转动连接，再将一第一连杆50的一端与导风组件30位于进风侧的侧边转动连接，另一端与第二连杆70转动连接，当需要使出风口211发散出风时，驱动第二连杆70靠近导风组件30运动，从而第一连杆50带动导风组件30绕固定支架10转动，进而带动导风组件30伸入出风口211的部分相对出风口211发散，即可使出风口211发散吹风；当需要使出风口211集中出风时，驱动第二连杆70远离导风组件30运动，从而第一连杆50带动导风组件30绕固定支架10转动，进而带动导风组件30伸入出风口211的部分相对出风口211聚拢，即可使出风口211集中吹风。如此，本申请技术方案可以使出风口211具备集中吹风和发散吹风的功能，提升用户体验。
在本申请的一实施例中，外壳210的大致呈圆筒状设置，其材质可以采用硬质塑料或轻质合金，只要能使外壳210具备一定的支撑功能即可，并且其内部形成有安装空间，可以理解的是，空气循环器200的部分部件安装于该安装空间内。该出风口211将空气循环器200的安装空间与外部空间连通，在本实施例中，出风口211大致呈扇形设置，以及该出风口211的开口角度可以根据实际需要进行设置，并且其形状也可以根据空气循环器200的出风要求进行设定。
以及，该固定支架10邻近出风口211安装固定，如此设置方便固定支架10与导风组件30的连接，需要说明的是，该固定支架10可以与外壳210一体成型设置，或者采用可拆卸的方式将二者相互连接，具体的，可以采用卡接件卡合或者使用扣合件将二者固定，当然，该固定支架10和外壳210还可以是不可拆卸连接的固定方式，具体的可以采用焊接固定等固定方式，只要能使二者较好的连接即可。
需要说明的是，两第一连杆50延其长度方向延长线相交，如此设置使得第二连杆70向前（靠近导风组件30）运动或向后（远离导风组件30）运动时，第一连杆50背离所述第二连杆70的端部相对远离或相对靠近运动，从而带动导风组件30绕固定支架10转动，使导风组件30相对出风口211张开或聚拢，使出风口211发散出风或集中出风。
可以理解的是，该两第一连杆50延其延其长度方向的延长线相交的位置改变时，第二连杆70驱动第一连杆50的效果相对应改变，从而使出风口211的聚散风效果改变。具体的，当该相交的位置位于进风侧时，驱动所述第二连杆70相对所述导风组件30靠近运动或远离运动，使所述第一连杆50带动所述导风组件30绕固定支架10转动，所述导风组件30伸入出风口211的部分相对出风口211张开或聚拢，以使所述出风口211发散吹风或集中吹风；当该相交的位置位于出风侧时，驱动所述第二连杆70相对所述导风组件30靠近运动或远离运动，使所述第一连杆50带动所述导风组件30绕固定支架10转动，所述导风组件30伸入出风口211的部分相对出风口211聚拢或张开，以使所述出风口211集中吹风或发散吹风。
参照图2，在本申请的一实施中，一所述导风组件30包括至少一导风板31，所述导风板31位于出风侧的侧边与所述固定支架10二者中的一个具有转接孔，二者中的另一个具有转动柱313，所述转动柱313插接于所述转接孔，以使所述导风板31与所述固定支架10转动连接。
在本实施例中，采用转接孔和转动柱313的方式实现导风板31和固定支架10转动连接，如此设置，使导风板31和固定支架10结构简单，并且具备较好的转接功能，降低生产成本。当然，还可以采用设置一固定副和一转动副，固定副和转动副之间通过滚珠或轴承等连接而实现转动。将导风板31位于出风侧的侧边转动连接，可以达到更好的导流效果。
参照图1、图3，进一步地，所述导风板31包括叶片311，所述叶片311伸入所述出风口211，所述叶片311的位于进风侧的侧边与所述第一连杆50转动连接，所述转动柱313设于所述叶片311的端部；
所述转接孔所述固定支架10，驱动第二连杆70相对导风板31靠近运动或远离运动，使所述第一连杆50带动所述叶片311绕转接孔的中心轴转动，所述叶片311相对出风口211张开或聚拢，以使所述出风口211发散吹风或集中吹风。
具体的，转动柱313位于叶片311出风侧的侧边，如此设置方便第二连杆70驱动第一连杆50，从而方便第一连杆50带动导风组件30转动，进而实现出风口211的集中出风和发散出风。
在本申请的一实施例中，将叶片311容置于出风口211，也即，导风板31主要通过叶片311实现对气流的聚拢或分散。可以理解的是，该导风板31可以为各种截面的形状，例如：空气动力学的翼型形状、矩形形状、弯曲形状等，只要方便出风即可，并且该导风板31集中吹风时，叶片311位于出风侧的侧面可以将出风口211朝向进风侧的边缘包络，从而使更多的空气被引导到中心开口处，进而实现更好的集中吹风效果，以及，该导风板31发散吹风时，叶片311位于出风侧的侧面可以将出风口211的内侧壁与叶片311之间的缝隙堵塞，从而使更多的空气被引导到中心开口处，从而实现空气的流速更高，从而具备更好的发散出风（广角出风）的效果。
参照图2至图4，在本申请的一实施例中，所述叶片311的位于进风侧的侧边端部和所述第一连杆50二者中的一个设有限位柱3111，二者中的另一个具有卡孔51，所述限位柱3111插接于所述卡孔51，以使所述第一连杆50与所述叶片311转动连接。本实施例中，通过限位柱3111和卡孔51的配合关系将第一连杆50与导风板31固定，如此可以使第一连杆50较好地带动导风板31转动，可以理解的是，该限位柱3111可以为多边形或圆形的柱体，该限位孔91的形状适配所述限位柱3111的形状设置。
进一步地，所述外壳210包括设于所述出风口211的分隔板20，所述分隔板20分隔两所述导风组件30，所述导风组件30包括至少两导风板31，两所述导风板31相互间隔设置；
所述叶片调节机构100还包括第三连杆90，所述第三连杆90与所述固定支架10所述第三连杆90的一侧与所述第一连杆50转动连接，另一侧设有至少两限位孔91，一所述限位柱3111插接固定于一所述限位孔91。
可以理解的是，该分隔板20对流出出风口211的风导流，从而使风的扩散范围更大。可以理解的是，一导风组件30包括多个导风板31，设置多个导风板31可以使得出风口211的导风效果更好，并且，多个导风板31被调整件驱动时，其转动角度应该为一致的，从而使其出风的气流相互平行，互不干扰。以及，当导风组件30包括多个导风板31时，设置与第一连杆50转动连接的第三连杆90，该第三连杆90邻近导风板31的一侧相应的具备多个限位孔91，从而使第三连杆90运动时，可以带动多个导风板31运动，进而出风板实现更好的集中出风和发散出风的效果。该第一连杆50连接于第三连杆90的位置，设于第三连杆90的中心处，如此设置可以使第一连杆50驱动第三连杆90的转动平衡，进而使位于分隔板20同侧的导风板31出风角度平行，方便出风，或者当第一连杆50连接于第三连杆90的其他位置时，对应改变转动柱313和限位柱3111的距离，从而使位于分隔板20同侧的导风板31出风角度平行，方便出风。
在本实施例中，该第一连杆50与第二连杆70、第一连杆50与第三连杆90之间的转动连接均采用，每二者之一采用凸柱93，二者之外采用插接孔53的方式，将凸柱93插接于插接孔53从而实现相互之间的转动连接。
进一步地，每一所述导风组件30位于出风口211的进风侧的一侧边设有多个间隔设置的插销315，所述固定支架10包括多个间隔设置的固定板11，所述固定板11沿所述出风口211的延伸方向排布；
每一所述固定板11均设有多个相互间隔的限位口111，每一所述插销315伸入一所述限位口111内。
设置多个插销315和多个限位口111的方式，可以使导风板31与固定支架10的转动连接更稳固，在本实施例中，出风口211沿上下方向延伸，可以理解的是，固定板11于固定支架10沿上下方向间隔排布，如此设置可以进一步提高导风板31与固定支架10的转接稳定性，进而提高导风板31的导风效果，提高出风口211的集中出风和发散出风。在本实施例中，限位口111的延伸方向与导风板31的转动方向一致，具体的，将限位口111的延伸方向设为圆弧状，如此设置，是导风板31的转动更方便，进而提高导风板31的导风效果，提高出风口211的集中出风和发散出风效果。
参照图2、图4，在本申请的一实施例中，所述第二连杆70形成有容纳部71，所述叶片调节机构100还包括偏心轮组件80，所述偏心轮组件80包括轮体81和自所述轮体81连接的调节杆，所述轮体81可活动地容纳于所述容纳部71内，并与所述容纳部71的侧壁抵接，所述调节杆自所述轮体81背离所述容纳部71的表面延伸；
驱动所述调节杆转动，所述轮体81抵接所述容纳部71的侧壁，带动所述第二连杆70相对所述导风组件30靠近运动或远离运动。
该容纳部71可以是滑槽或滑孔或滑动空间等，只要能方便轮体81在容纳部71内活动即可，其具体结构根据实际需要设定。具体的，该偏心轮组件80的轮体81大致呈圆盘状设置，该圆盘的侧边与容纳部71抵接，该圆盘的底部与容纳部71的底部抵接，该圆盘还形成有轴心，该杆体83自圆盘背离容纳部71的底部的表面延伸，并且该杆体83的轴心与圆盘形成的轴心互不重合，从而形成偏心设置，驱动杆体83转动，从而该轮体81的运动轨迹为非圆形，从而带动第二连杆70向前（靠近导风组件30）运动或向后（远离导风组件30）运动，方便驱动第二连杆70，从而方便实现聚散风。
进一步地，所述偏心轮组件80还包括杆帽85，所述杆帽85套接固定于所述调节杆背离所述轮体81的一端。设置杆帽85可以方便用户转动杆体83。可以理解的是，外壳210还形成有贯穿孔，该杆体83的一端伸出贯穿孔，杆帽85套接于杆体83伸出贯穿孔的一端，从而使叶片调节机构100在外壳210的保护下更好的工作，方便用户使用。
在本申请的一实施例中，所述第二连杆70与所述固定支架10二者中的一个具有导向限位槽73，二者中的另一个具有限位凸块13，所述限位凸块13伸入于所述导向限位槽73，限位所述第二连杆70相对所述固定支架10的运动。
设置导向限位槽73和限位凸块13使第二连杆70和固定支架10的相对运动位置固定，具体的，该导向限位槽73的延伸方向为前后方向，如此设置方便第二连杆70在最短的距离驱动第一连杆50，提高响应。当然，该导向限位槽73的设置方向还可以根据实际需要设定，只要能使第二连杆70较好的驱动第一连杆50即可。以及，该导向限位槽73可以设置为两个或多个，当设置为多个时可以为左右对齐或者前后对其的方式，只要能使第二连杆70较好的驱动第一连杆50即可。
可以理解的是，第二连杆70的运动范围和两导风板31之间的间距等影响叶片调节机构100的导风板31的转动角度范围，在本实施例中，导风板31的角度范围为5度至45度。并且，还可以在设置驱动组件驱动旋钮转动，并通过控制电路控制驱动组件，如此，方便用户使用。具体的，该驱动组件可以为同步电机或步进电机等，只要方便使用即可。以及，该叶片调节机构100也可以安装于外壳210的安装空间外，只要方便用户使用即可。
