在以下的说明中，将涉及对智能药箱组件中的多个技术改进，在不冲突的情况下，这些技术改进可以全部或部分地以适当方式组合使用。可以理解的是，可以在不脱离本公开的技术构思的情形下对智能药箱组件中的相关结构和连接关系进行简单变型以获得其他变型的技术方案。在智能药箱组件使用过程中，盖体和测量组件属于易损件，同时，该智能 药箱组件并不限定为必然地具有与其连接的药箱本体。
相关技术中的一些可用于植保机械的储液箱，一般设有液位传感器，该液位传感器通过浮子随着液位的变化而触发不同高度位置处的磁性开关，从而可以测量储液箱内的液位。但是，一般地，液位传感器集成在储液箱盖上，该储液箱盖包括限定有容纳空间的上盖和下盖，并将连接液位传感器的处理器设置于容纳空间中。上述相关技术存在如下缺陷：在打开和关闭储液箱盖时，会使得集成的液位传感器一同动作，使用不便。
本实施例提供的智能药箱组件100可以缓解该技术问题。具体地，以下将对本实施例提供的智能药箱组件100进行详细的介绍。
图1所示为一种可用于如植保无人机等植保机械的智能药箱组件100，包括药箱本体1、盖体2和测量组件3。药箱本体1可以形成为具有大体呈倒L形截面的结构，以具有相对较大的容积并能够方便地安装至植保无人机的机体上。盖体2和测量组件3可以安装至形成在药箱本体1上的安装孔11。通常地，该安装孔11形成在药箱本体1的顶壁上，作为注入药液的注液孔。在药箱本体1的内腔12内的药液喷洒完或少于预定量时，可以拆下盖体2和测量组件3，并通过该安装孔11注入药液。注入药液完成后，再将测量组件3安装延伸至药箱本体1内，盖体2连接至药箱本体1的安装孔11上，并将测量组件3压紧固定至药箱本体1上。
具体地，在本实施例的描述中，在未作相反说明的情况下，使用的方位词例如“顶部、顶壁、底部、底端”等通常是指参考附图1所示的方位，例如测量组件3的顶部为该测量组件3靠近盖体2的部分；测量组件3的底部为该测量组件3伸入至药箱本体1内的靠近其箱底的部分(安装状态下)。同样地，使用的方位词如“内、外”是指相对于各部件本身轮廓的内、外。
结合图1和图2所示，在安装状态下，测量组件3可以穿过安装孔11延伸至药箱本体1内，以便实时测量其中的液位、药液温度等参数。盖体2连接至安装孔11并将测量组件3压紧固定至药箱本体1(具体地，固定至安装孔11中)。本实施例中，药箱本体1的安装孔11外周壁上形成有外螺纹111，盖体2的内周壁形成有与外螺纹111配合的内螺纹203，由此可以通过将盖体2拧紧至安装孔11而将测量组件3压紧固定并封闭该安装孔11。可选地，盖体2也可以通过卡接等方式连接至安装孔11。
本实施例中，智能药箱组件100的盖体2与测量组件3相对独立地设置(测量组件3未集成于盖体2)，因而可以在拆装时将测量组件3沿着安装孔11(具体地，为圆孔)的轴向插入或拉出，进而利用盖体2压紧固定。由此，可以避免测量组件3在如拧紧盖体2时随同转动，能够容易地完成各部件的拆装。同时，在拆装过程中，可以避免测量组件3随着盖体2转动而搅动药箱本体1内的药液，可以降低该测量组件3因药液冲击作用而引发变形、损坏、测量不准等问题的可能性。
参照图2至图10，智能药箱组件100的测量组件3大体可以分为配置成传感药液信息的液位传感模块(伸入至药箱本体1内)和配置成接收、处理药液信息的数据处理模块，液位传感模块可以包括延伸至药箱本体1内的液位传感器303，数据处理模块可以包括电连接于该液位传感器303的主板302等。由于在作业过程中需要向液位传感器303通电，因而应当避免主板302和液位传感器303与药箱本体1内的药液接触。这里的液位传感器303和主板302均可采用现有技术中的产品，因此，其原理和作用效果等不做赘述。
同时，为了使得药箱本体1内的药液顺利向外喷洒，可以设置药箱通气结构，配置成使药箱本体1的内腔12与外部空间200保持压力平衡。采用传统技术，例如，将液位传感元件与药箱通气结构分开布置，可以较好地避免药箱通气结构排气携带的药液湿气损坏如主板302的电子器件，但增加了智能药箱组件100的制造成本和结构复杂度。
为此，在本实施例中，可以将药箱通气结构集成设置在测量组件3，在降低结构复杂度的前提下通过设置主板302和气流通道30511可以避免药液湿气接触主板302。具体地，测量组件3可以具有上壳体304和下壳体305，上壳体304可拆卸地密封连接至下壳体305以形成容纳腔301，主板302安装于该容纳腔301中。药箱通气结构可以具有配置成通气的气流通道30511，只要使得该气流通道30511与容纳腔301隔绝，即可防止药液湿气接触主板302。需要说明的是，测量组件3包括的两个壳体也可以是呈左右分布的，例如其包括左壳体和右壳体，左壳体和右壳体可拆卸地密封连接以形成容纳腔301。
本实施例中，如图3、图6至图9所示，下壳体305可以具有配置成坐落于药箱本体1的安装孔11上的边缘部，该边缘部环绕形成凹腔，构成容纳腔301的主体部分。该下壳体305设有连接管3051，该连接管3051具有与容纳腔301隔绝的气流通道30511，并使得药箱本体1的内腔12与外部空间200连通。由此可以保持药箱本体1的内腔12与外部空间200的压力平衡，药液能够顺畅排出。同时，通过将药箱通气结构集成设置在测量组件3 上，无需额外地在药箱本体1上设置透气孔，可以将实现注液、测量和透气的结构共同设置于作为注液孔的安装孔11中，降低了智能药箱组件100的结构复杂度。需要说明的是，上述提及的“外部空间200”指的是位于智能药箱组件100外的空间。即，通过连接管3051可使得药箱本体1的内腔12与大气保持连通。
其中，在通过下壳体305上的连接管3051通气以保持药箱本体1内外气压平衡时，药箱本体1内的药液可能会因振动等从连接管3051溢流。为此，还可以在连接管3051朝向药箱本体1内的一侧连接通气管307，从而，即使在工作过程中药箱本体1内的药液发生飞溅，其也不能直接通过连接管3051溢流至外部空间200。具体地，盖体2上形成有通气孔21，药箱本体1的内腔12依次通过该通气管307、连接管3051和通气孔21与外部空间200连通。
在本实施例中，通气管307至少具有一个完整螺旋。结合图6和图7所示，下壳体305可以设有前述连接管3051和与该连接管3051间隔的连通管3053，通气管307的一端连接至连接管3051，通气管307的另一端连接至该连通管3053并通过该连通管3053与药箱本体1的内腔12连通。该两端之间的中间部分螺旋延伸并设有至少一个完整螺旋。由此，若药液在连通管3053处飞溅进入通气管307，这部分药液需要克服重力进一步通过螺旋顶部才有可能从连接管3051溢出，因而这种设置能够有效降低药液溢出的可能性。通气管307可以为由如橡胶制成的柔性管，并由束箍件连接形成完整螺旋。此处的束箍件是指能够将两个或多个管段围束在一起的连接元件。
通气管307可以以多种现有的方式在连通管3053处连通至药箱本体1的内腔12。在图7所示的结构中，连通管3053的侧壁上形成有缺口3053a，通气管307插装在该连通管3053上并在该连通管3053的根部位置被凸起结构(未标记)支撑，以能够通过该缺口3053a连通药箱本体1的内腔12。可选地，也可以是连通管3053未设置有缺口3053a，通气管307过盈配合在连通管3053上，然后通过对通气管307和连通管3053的侧壁钻孔的方式实现通气管307与药箱本体1的内腔12连通。
在连接管3051的另一端，可以通过盖体2上的通气孔21与外部空间200连通。如图5所示，盖体2大致呈圆柱状，其可以具有轴向相接的大径部23和小径部24，大径部23的内周壁上可以形成有螺接至药箱本体1的安装孔11上的内螺纹203，大径部23的外周壁上形成有交替布置的凹部231和凸部232，操作人员可以通过该凸部232拧动盖体2以 实现拆装。通气孔21形成在小径部24上。由此，当药液通过该通气孔21溢流时，由于大径部23的外径大于小径部24的外径，可以在一定程度上避免药液流到凸部232的径向表面，从而降低操作人员接触药液的可能性，即，即使药液通过通气孔21流出，基本上也只能流至凹部231内。
图8所示的测量组件3的上壳体304中。该上壳体304具有盖体支撑部3044、壳体连接部3045和凸起部3041，该凸起部3041上形成有配置成安装按键电路板308的沉槽3043。具体地，盖体支撑部3044支撑于安装孔11的上沿，盖体2安装到安装孔11上后，能够压紧该盖体支撑部3044。更具体地，由于盖体2的周壁201内侧形成有螺接至安装孔11上的内螺纹203，当盖体2安装到安装孔11上后，盖体2的顶壁202的底侧压紧该盖体支撑部3044。
结合图3、图6、图8和图9所示，上壳体304可拆卸地密封连接于下壳体305上，以便保持容纳腔301的密封性并能够更换位于该容纳腔301内的如电池、主板302等元件。具体地，下壳体305朝向上壳体304的一侧周缘可以形成有环形槽3052，该环形槽3052内设有密封环312，上壳体304压紧于该密封环312并通过穿过壳体连接部3045的第二螺纹紧固件316(例如，螺钉)固定于下壳体305上。
上壳体304的壳体连接部3045可以形成有定位凹槽3042，下壳体305上的连接管3051可以穿过该定位凹槽3042延伸，以限定上壳体304与下壳体305的周向相对位置，便于定位安装。
在对应于上壳体304的凸起部3041的位置，盖体2可以具有中心通孔22。在安装状态下，盖体2罩设至上壳体304上，并使得凸起部3041伸入至中心通孔22内，盖体2的顶壁202内侧支撑于盖体支撑部3044以压紧固定测量组件3。具体地，盖体支撑部3044支撑在安装孔11的上沿，盖体2压紧该盖体支撑部3044，以实现将整个测量组件3压紧固定至药箱本体1上。
本实施例中，测量组件3设有安装至上壳体304的按键电路板308，按键电路板308可以通过第一螺纹紧固件314(例如，螺钉)固定于沉槽3043内。为了保证容纳腔301的密封，可以在按键电路板308朝向容纳腔301的一侧设置防水硅胶313。该按键电路板308可以通过弹簧顶针连接器309电连接于主板302，由此能够通过盖体2的中心通孔22直接 操控按键电路板308上的按键，无需拆下盖体2即可实现测量组件3的启停操作，有效改善了使用便利性。其中，在按键电路板308背离容纳腔301的一侧也可以设置防水硅胶313，并在凸起部3041的顶面上设置按键贴膜315，以改善美观性和操作手感。
测量组件3通过电连接于主板302的液位传感器303感测药箱本体1内的液位变化。液位传感器303可以形成为多种适宜的形式。本实施例中，液位传感器303可以包括电路板和设置于该电路板上的多个磁性开关，该磁性开关可以由浮子311(下详述)触发以获得相应的液位信号。为了避免通电元件与药箱本体1内的药液接触，本实施例中，利用传感器护筒306(具体地，为圆筒)将液位传感器303与药液隔绝，液位传感器303可以设置于该传感器护筒306内。例如，前述设置磁性开关的电路板可以为条状，并延伸至该传感器护筒306内。即，该测量组件3还包括从下壳体305向药箱本体1内延伸的传感器护筒306，液位传感器303穿过下壳体305延伸至传感器护筒306内。
对于传感器护筒306的细长结构，一体成型会导致较高的开模成本。在本实施例中，传感器护筒306构造成包括可拆卸地连接的多个护筒段3061。如图3和图10所示。由此，各个护筒段3061可分别成型，并相互连接形成所需的传感器护筒306。通过这种设置，还可以根据适配的药箱本体1的尺寸(深度)而选择连接形成的传感器护筒306的长度，适应性较好。
上述多个护筒段3061可以具有相同或不同的长度。在图3所示中，传感器护筒306的多个护筒段3061包括基础护筒段306a、续接护筒段306b和底端护筒段306c。其中，基础护筒段306a可以与下壳体305形成为一体，其底端连接一个或多个续接护筒段306b，在该续接护筒段306b远离基础护筒段306a的一端连接一底端护筒段306c。为了便于连接并保证较好的密封性，各个护筒段3061的端部可以形成有螺纹部3062，例如续接护筒段306b一端可以具有内螺纹，另一端具有外螺纹，以利用螺纹连接本身的密封性防止药液通过连接部位进入传感器护筒306内。
传感器护筒306内的液位传感器303可以由随药液量变化而升降的浮子311触发，该浮子311可以以适当的方式保持与液位传感器303的间距，以保证测量准确性。在图2、图3中，测量组件3还包括与传感器护筒306并行延伸的浮子导杆310，浮子311滑动套设于该浮子导杆310上。
浮子导杆310可以为不锈钢空心管，以减小药液腐蚀速度。该浮子导杆310的一端设有卡夹317，配置成与传感器护筒306的顶部的卡止槽3063卡合固定，浮子导杆310的另一端设有具有周向限位结构的限位件319，配置成与传感器护筒306的底部通过螺纹端盖318固定，以能够具有较好的装配性和测量精度。
具体地，在基础护筒段306a相应于浮子导杆310顶端部的位置设有卡止槽3063，卡夹317可以卡止于该卡止槽3063中；在底端护筒段306c的外周壁上形成有与限位件319配合的周向限位结构，以能够限定浮子导杆310与传感器护筒306的周向相对位置，避免浮子导杆310的底端绕传感器护筒306的中心轴线转动，保持浮子311在平行于传感器护筒306的中心轴线的方向上下浮动，保证较高的测量精度。
前述底端护筒段306c和限位件319的周向限位结构可以为形成在底端护筒段306c底端部外周面上的外齿部3064和形成在限位件319上的内齿部3191，如图4所示。由此，为了便于装配，可以在限位件319上形成有彼此间隔并平行延伸的通孔和盲孔，内齿部3191形成在通孔内，浮子导杆310插装于盲孔中，该限位件319可以由连接至传感器护筒306底端的螺纹端盖318固定。在装配时，可以首先将多个护筒段3061相接形成传感器护筒306，进而将限位件319套设于底端护筒段306c上并使得周向限位结构相互配合，然后将螺纹端盖318螺接于传感器护筒306的底端，以夹持固定限位件319，并封闭传感器护筒306的底端开口(若有)。之后，将连接有卡夹317的浮子导杆310的底端插入限位件319的盲孔中，并将卡夹317夹持于传感器护筒306上的卡止槽3063。
为了更好地实施植保作业，除了对药箱本体1内的液位进行监测外，还可以利用测量组件3监测药液温度。为此，可以在传感器护筒306的底端部的位置设置温度传感器，例如，该温度传感器可以设于底端护筒段306c。
本实施例还提供了一种植保机械，该植保机械包括上述的智能药箱组件100。
该植保机械可以为植保无人机，智能药箱组件100安装至植保无人机的机体上。该植保机械也可以为植保无人车，智能药箱组件100安装至植保无人车的车体上。该植保机械具有该智能药箱组件100的全部功能。
