本实施例中，该装配载体为无人机，水箱应用于无人机中以使无人机具有喷洒功能，具体地该无人机可以为植保无人机。当然，本发明的水箱10并不限于应用于无人机中，其他需要使用水箱的装置均可以使用本发明的水箱10。以下实施例中装配载体以无人机为例进行详细描述。
如图1、图2配合图6所示，该阀控组件2包括阀壳体21以及装配于阀壳体21内的密封件22，该密封件22可在外力作用下相对阀壳体21移动。可选地，密封件22可沿阀壳体21的中轴线方向移动。其中，该密封件22与阀壳体21配合以使阀控组件2处于密封状态；或者密封件22在外力作用下脱离于阀壳体21以使阀控组件2处于开启状态。本实施例中，该阀控组件2在初始时，密封件22封堵于阀壳体21中的水流通道，以使阀控组件2处于密封状态；在水箱10装配于无人机100时，通过无人机100的部件作用于密封件22，以使密封件22脱离于阀壳体21，从而使阀控组件2处于开启状态，如此在水箱10装配于无人机100的机架101后即与机架101内的流道连通。
如图2和图3所示，该阀壳体21包括主壳体211以及设置于主壳体211内且部分固定于主壳体211的内壳体212，该内壳体212设置于主壳体211的中间位置，该内壳体212可以与主壳体211一体成型制成。其中，该内壳体212与主壳体211之间具有流道，密封件22穿设于内壳体212，如此以使密封件22悬接在阀壳体21内。具体地，该密封件22穿设于内壳体212内且可以沿内壳体212的中轴线的轴向移动。
如图2和图4所示，本发明的密封件22包括阀芯221、设置于阀芯221一端的密封部222、以及设置于阀芯221另一端的限位部223。其中， 该阀芯221为圆柱状或者条状，阀芯221装配于内壳体212内且可相对内壳体212滑动，具体阀芯221沿内壳体212的中轴线的轴向移动。该密封部222与主壳体211的上端部适配以封堵或开启主壳体211内的水流通道，该限位部223用于与内壳体212配合从而限制密封件22的移动范围。
其中，主壳体211的上端部朝向密封部222的表面包括自上而下向密封部222中轴线方向倾斜的斜面。相对应地，该密封部222在朝向限位部223的方向上具有自上而下减小的宽度，如此设计可以便于密封部222引导装配于主壳体211内，并且在装配过程中以使密封部222与上端部愈发紧密。
本发明的密封部222可拆卸地装配于阀芯221上，限位部223可以与阀芯221一体成型设置。通过密封部222可拆卸地装配于阀芯221，如此以便于将密封件22装配于主壳体211内且限制在内壳体212上。
在一实施例中，该密封部222包括堵头主体2221、锁配件2222以及设置于堵头主体2221周侧的堵头密封圈2223。其中，堵头主体2221通过锁配件2222连接于阀芯221。具体地，该堵头主体2221中设有连接孔，阀芯221的端部设有螺纹孔，锁配件2222为螺钉。在密封部222装配于阀芯221时，阀芯221从连接孔的下端装配入，螺钉从连接孔的上端装配入且螺纹锁紧于阀芯221，该螺钉的螺帽与堵头主体2221的配合处设有密封垫2224，以避免密封部222与阀芯221的连接处漏水。在又一实施例中，该密封部222为具有内螺纹的密封堵头，阀芯221的端部设有螺纹，该密封堵头通过内螺纹与阀芯221的螺纹密封连接。
当然，在其他实施例中，也可以使密封部222与阀芯221一体成型设置，限位部223可拆卸地装配于阀芯221；密封部222与限位部223均可拆卸地装配于阀芯221；或者密封部222与限位部223均与阀芯221一体成型设置，如此也可以满足便于将密封件22装配于主壳体211内且限制在内壳体212上。
如图2、图4配合图6至图8所示，该限位部223相背阀芯221的一端还设有配合部225，在水箱10装配于无人机100的机架101时，机架101上的定位部431与配合部225匹配预定位，从而可以将作用力全部作用于密封件22，实现对密封件22的准确控制。具体地，该配合部225可以为一凹槽，定位部431为与凹槽匹配的凸起，或者配合部225为凸起，定位部431为凹槽。
进一步地，该阀控组件2还包括设置于限位部223与内壳体212之间的弹性件224。其中，当密封部222脱离于主壳体211时，阀控组件2处于开启状态，弹性件224压缩且形成以使阀控组件2回复至密封状态的回复力。
本实施例中，该弹性件224为套设于阀芯221的弹簧，该弹簧限制在内壳体212与限位部223之间。该弹簧处于初始状态时(即不受外力作用时的状态)，密封件22与阀壳体21配合密封；当阀控组件2处于开启状态时，弹簧则处于压缩状态，在外力消除后，弹簧则驱使密封件22回复至与阀壳体21配合的密封状态。当然，在其他实施例中，该弹性件224也可以为套设于阀芯221上的橡胶圈、塑料圈或波形管等，弹性件224还可以为连接在内壳体212与限位部223之间的弹片。
阀控组件2可以设置于箱体1的底部，该箱体1的液体可以在液体的压力下流向装配载体。当然，根据结构特征需求，该阀控组件2还可以设置于箱体1的侧面，在水箱10与装配载体连通后，通过水泵的作用可以使水箱10内的液体流向装配载体。如图1和图2所示，在阀控组件2设置于箱体1的侧面的实施例中，该箱体1包括相互连通的上部箱体11和下部箱体12，上部箱体11部分凸出下部箱体12，即上部箱体11的横向尺寸大于下部箱体12的横向尺寸，如此设计以使水箱10可以适配无人机100的机架101。其中，该阀控组件2设置于上部箱体11凸出下部箱体12的下方空间。
本发明的水箱10还包括设置于箱体1内的液位计16，通过该液位计16可以获知水箱10内液体的容量。本实施例中，该液位计16为两个，一个设置于上部箱体11，一个设置于下部箱体12内。当然，为了更加精准地获取液体容量，可以在上部箱体11和下部箱体12内设置更多数量的液位计16。
该水箱10还包括管路13。其中，该管路13的一端连通于阀控组件2，另一端连通于箱体1的底部，以与箱体1内的容纳腔连通。本实施例中，将管路13的一端连通于箱体1的底部，可以使箱体1内的液体全部流出，避免部分液体始终留存在箱体1内。
相对应地，该水箱10还包括连接于管路13与阀控组件2的安装座3，该安装座3起到衔接作用，如此以使管路13与阀控组件2实现连接。具体地，该安装座3为U型结构，装配在上部箱体11与下部箱体12的连接拐角处。
相对应地，如图3所示，该阀壳体21还包括从主壳体211向外延伸出的装配段壳体213，阀壳体21通过装配段壳体213密封装配于安装座3。该装配段壳体213与主壳体211的上端部之间形成装配空间，装配段壳体213上设有螺纹并通过螺纹连接装配于安装座3的一端，安装座3的另一端则与管路13连接。此外，为了增强阀壳体21与安装座3之间的密封性，在装配空间内还设有装配密封圈215。
如图5所示，本发明的水箱10还包括设置于箱体1顶部的注液口15以及装配于注液口15的盖体(未图示)，该注液口15倾斜设置，从而便于为水箱10加液。此外，该水箱10的箱体1顶部还设有手提把手14，用户通过该手提把手14便于对水箱10进行拆卸、装配及运输。
本发明设计了一种可以即插即用的水箱，该水箱上设有初始密封的阀控组件。水箱装配于无人机的过程中，阀控组件在外力的作用下处于开 启状态，在水箱脱离于无人机时，阀控组件在弹性的作用下可以回复至密封状态，如此以使水箱装配后即完成与无人机的连通，实现了水箱可快速拆卸的需求，从而可以便捷地为水箱加液，可以极大地提高作业效率。
如图5至图8所示，根据本发明实施例的又一方面，还提供了一种无人机100，该无人机100包括：机架101、设置于机架101上的机架底座4以及装配于机架101的水箱10。该水箱10在装配于机架101后通过与机架底座4配合而使得水箱10与机架101上的流道连通。其中，该水箱10的结构如上述各个实施例所述，在此不再赘述。
其中，在水箱10装配于机架101时，机架底座4抵持于水箱10中阀控组件2的密封件22，以使阀控组件2处于开启状态，此时弹性件224处于压缩状态，如此即实现了水箱10的即插即用的功能，无需再通过其他结构的调节而使水箱10与机架101上的流道连通。在机箱从机架101上拆卸时，该阀控组件2在弹性件224的作用下回复至密封状态，如此可以简化对水箱10的操作步骤，提高该水箱10的便捷性，而且可以方便用户将水箱10拆卸出为水箱10加液。
机架底座4开设有安装槽42，安装槽42内设置有抵持件43。其中，当水箱10装配于机架101时，抵持件43抵持于阀控组件2的密封件22，以使得阀控组件2处于开启状态。机架底座4内设有底座流道，抵持件43镂空设置以使安装槽42与机架101上的流道连通。其中，该安装槽42的槽口呈喇叭状，如此以便于阀控组件2装配于机架底座4上。此外，为了增强阀控组件2与机架底座4装配的密封性，阀控组件2的主壳体的下端部的周侧面还设有主壳体密封圈214。
该抵持件43上还设有定位部431，该定位部431用于与密封件22上的配合部225进行预定位，从而避免抵持件43的力未全部施加到密封件22上。在水箱10装配于无人机100的机架101时，机架101上的定位部431与配合部225匹配预定位，从而可以将作用力全部作用于密封件22， 实现对密封件22的准确控制。具体地，该配合部225可以为一凹槽，定位部431为与凹槽匹配的凸起，或者配合部225为凸起，定位部431为凹槽。
此外，该无人机100还包括连接于机架101上的脚架102以及连接于机架101上的旋翼组件(未图示)，该脚架102用于起到支撑作用，旋翼组件为多个，用于控制该无人机100的飞行。其中，本发明的无人机100具体地可以为植保无人机，用于农业喷洒农药及洒水等。
本发明设计了一种水箱及具有该水箱的无人机，当该水箱在单独放置时，阀控组件在弹性件的作用下使得密封件与阀壳体紧密压合进行密封，水箱的出水口密封，不漏液。当水箱装配于无人机的机架时，机架上的抵持件抵持于密封件，此时克服阀控组件中的弹性件的弹性力以使弹性件压缩，密封件的密封堵头脱离于阀壳体，以使阀控组件处于开启状态，如此即打开了水箱的出水口，以使水箱装配后即完成与机架上的流道连通，实现了水箱可快速拆卸的需求，从而可以便捷地为水箱加液，可以极大地提高作业效率。
