现有技术中，植保无人机内设置有喷洒装置、药箱和泵，泵用于将药箱内的药水输向喷洒装置。植保无人机在飞行过程中，同时对农作物进行喷水药水，一般的，植保无人机的飞行速度根据喷洒装置喷洒出的药水的量来决定。为了保证农作物不少喷药和不多喷药的前提下，提高植保无人机的工作效率，发明人尝试了通过改变泵的输出功率、改变控制喷洒装置的阀门的大小等方式来改变植保无人机的飞行速度，但是，会出现农作物少喷药或者多喷药的情况。
发明人在大量的研究中发现，通过安装两个不同的喷嘴，并通过换向阀来控制不同的喷嘴可以在保证农作物不少喷药和不多喷药的前提下，实现间接控制植保无人机的飞行速度，进而提高植保无人机的工作效率。以下对该喷头组件进行详细介绍。
实施例1
请参照图1，本实施例提供了一种喷头组件100，其包括换向阀13、第一喷嘴11和第二喷嘴12；
换向阀13具有第一输出部和第二输出部；
换向阀13的第一输出部与第一喷嘴11的输入部连通，换向阀13的第二输出部与第二喷嘴12的输入部连通；

请参照图1，换向阀13的第一输出部与第一喷嘴11连通，换向阀13的第二输出部与第二喷嘴12连通，需要说明的是，第一输出部和第二输出部不能同时输出药液，即第一喷嘴11和第二喷嘴12相互独立工作，且不能同时喷洒药液。
值得注意的是，第一喷嘴11的喷孔的孔径的尺寸与第二喷嘴12的喷孔的孔径的尺寸是不相等的，也就是说第一喷嘴11和第二喷嘴12采用不同型号的喷嘴。需要说明的是，不同型号的喷嘴的额定压力值不一样，喷洒出的药液的尺寸也是不一样的。
本实施例中，第一喷嘴11和第二喷嘴12采用不用型号的喷嘴，工作人员可以根据实际情况切换第一喷嘴11和第二喷嘴12喷，同时可以改变植保无人机的飞行速度，提高植 保无人机的工作效率。
请参照图2-图3，在本实施例中，喷头组件100还包括人字形的第一基体14；

需要说明的是，在本实施例中，第一连接件141、第二连接件142和第三连接件143均为圆柱形结构，第一连接件141的轴线、第二连接件142的轴线和第三连接件143的轴线两两平行，第二连接件142和第三连接件143对称分布在第一连接件141的两侧。
第二连接件142远离第一连接件141的一端与第一喷嘴11连接，第三连接件143远离第一连接件141的一端与第二喷嘴12连接。请参照图2，第一连接件141、第二连接件142、第三连接件143、第一延伸件20和第二延伸件21形成人字形结构。
需要说明的是，当喷头组件100与植保无人机连接时，这种人字形结构可以保证第一喷嘴11和第二喷嘴12竖直朝下，可以更好的对农作物喷洒药水，提高植保无人机的工作效率。
需要说明的是，在其它实施例中，也可不采用第一延伸件20和第二延伸件21，可以将第一连接件141、第二连接件142和第三连接件143直接一体注塑出来。
请参照图3-图5，在本实施例中，喷头组件100还包括用于与植保无人机连接的第二 基体15；
第一连接件141远离第二连接件142的一端设置有第一环形齿1411；
第二基体15设置有第二环形齿151；
第一环形齿1411和第二环形齿151相互啮合，且第一基体14和第二基体15能够相对固定。
第一连接件141设置有第一通孔1413，第一通孔1413的轴线方向与第一连接件141的轴向方向一致；
第一连接件141的内壁沿第一连接件141的径向凸设有连接部1412，连接部1412与第二基体15可拆卸连接；
连接部1412与第一连接件141的内壁之间形成用于管道通过的容纳空间1415；
第一连接件141的两侧对称设置有第一槽孔1414和第二槽孔(图中未示出)，第一槽孔1414和第二槽孔(图中未示出)均与容纳空间1415连通。

工作人员可以将第一连接件141和第二基体15拆卸下来，然后旋动一定的预设角度，旋动一定角度后，第一连接件141和第二基体15通过第一环形齿1411和第二环形齿151啮合，可以保证第一连接件141和第二基体15的在第一连接件141的周向上相对固定，即此时的第一连接件141和第二基体15不会产生相对转动，避免影响之前预设的角度。然后，工作人员可以通过螺栓将第一连接件141与第二基体15连接，使第一连接件141与第二基体15相对固定。
需要说明的是，由于连接部1412位于第一连接件141的内部，工作人员在拆装第一连接件141时，工作人员手持的拆装工具，需要通过第一连接件141上的第一通孔1413从而完成拆装作业。具体的，工作人员手持拆装工具，从图4中的第一连接件141的下方进入，通过第一通孔1413完成对螺栓的拆装，从而完成第一连接件141的拆装。
请参照图3，连接部1412与第一连接件141的内壁之间形成了一个容纳空间1415，该容纳空间1415可以通过连通第一喷嘴11和第二喷嘴12的管道，请参照图4，第一连接件 141的两侧还对称设置有第一槽孔1414和第二槽孔(图中未示出)，第一槽孔1414和第二槽孔(图中未示出)均与容纳空间1415连通，植保无人机中的输液管道可以通过容纳空间1415、第一槽孔1414和第二槽孔(图中未示出)，从而实现与第一喷嘴11和第二喷嘴12连通。设置该第一槽孔1414和第二槽孔(图中未示出)还可有效的节约第一连接件141的材料，降低生产成本。
值得注意的是，设置容纳空间1415、第一槽孔1414和第二槽孔(图中未示出)的设置方式可以保证植保无人机上的输液管道位于第一通孔1413内部，可以有效的防止管道被刮伤，同时，将管道集合在第一通孔1413内部不会影响植保无人机的飞行，保证植保无人机的工作效率。
