Description

电磁阀和可移动平台 技术领域
本发明涉及密封阀领域，特别涉及电磁阀和采用该电磁阀的可移动平台。
背景技术
在工业和农业等领域，常常需要对管道中的流体(气体或液体)进行自动控制。例如在农业无人机、农药喷洒车、人力喷洒装置等设备上通常需要对多条管道(包括多个出口)进行自动通断控制。这时一般采用在每个管道上分别设置一个可在电信号控制下开合的阀体，对每条管道的通断进行单独控制。然而，这种控制方式结构复杂，成本高，体积、重量大，控制信号多。
除此之外，现有的阀体依靠弹簧实现密封，阀体关闭后，如果管道中流体压力过高，弹簧会在流体的压力下被顶开，出现泄露现象，难以保证管道的良好密封。

具体实施方式
为了使发明的目的、技术方案和优点更加清楚，下面结合附图和具体实施例对发明作进一步详细的说明。虽然附图中显示了本公开示例性实施例，然而应当理解，可以以各种形式实现本发明而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更便于透彻的理解本发明， 并且能够将本发明的构思完整的传达给本领域人员。
请参照图1～5，本发明的一个实施例提供了一种电磁阀，包括静止部1、运动部2、驱动部3以及连通管4。具体地，静止部1设有进液/进气通道11，液体或气体从进液/进气通道11流入电磁阀。运动部2设有与进液/进气通道11相连通的液体/气体通道21，运动部2能够相对静止部1运动(如图4所示的上下方向运动)。驱动部3用于驱动运动部2靠近静止部1。连通管4具有一个进液/进气口41和至少一个出液/出气口42，液体或气体从至少一个出液/出气口42流出电磁阀。上述的运动部2远离静止部1的一端形成密封端22，当运动部2保持远离静止部1时，运动部2凭借密封端22密封连通管4的进液/进气口41。当运动部2在驱动部3的驱动力作用下靠近静止部1时，进液/进气通道11和进液/进气口41被连通，以使得从进液/进气通道11流入电磁阀的液体/气体流经液体/气体通道21后，从进液/进气口41进入连通管4，并从至少一个出液/出气口42流出电磁阀。
进一步地，运动部2的密封端22上设置有密封塞，运动部2凭借密封塞密封连通管4的进液/进气口41。
进一步地，当运动部2保持远离静止部1时，液体/气体通道21中的液压/气压能够持续地施加于密封端22，从而将密封端22向进液/进气口41压紧。
基于上述结构，本领域技术人员应当能够理解，液体或气体由静止部1的进液/进气通道11流入电磁阀后，如果运动部2处于远离静止部1的位置，则液压/气压会持续地施加于密封端22，促使密封端22向进液/进气口41压紧。换句话说，液体或气体提供的液压/气压越大，密封端22向进液/进气口41压的越紧。因此，本实施例提供的电磁阀处于关闭状态时，能够提供更好的密封，防止液体或气体泄露。
再者，在本实施例中，静止部1和运动部2上形成了进液/进气通道11和液体/气体通道21，因此不必从连通管4中设置进液/进气通道11和液体/气体通道21，使得整个电磁阀的结构更为简单，体积和重量更小，从而能够应用于更多的场合，特别是无人机。
进一步地，当运动部2保持远离静止部1时，进液/进气通道11靠近运动部2的一端与液体/气体通道21靠近静止部1的一端之间存在间隙。当运动部2在驱动部3的驱动力作用下靠近静止部1时，运动部2与静止部1抵接，进液/进气通道11靠近运动部2的一端与液体/气体通道21靠近静止部1的一端紧密相接。
进一步地，运动部2至少部分套设在静止部1内。也可以是，静止部1至少部分套设在运动部2内。
进一步地，运动部2至少部分套设于进液/进气通道11内；或者，静止部1至少部分套设在液体/气体通道21内。
进一步地，在本实施例中，进液/进气通道11穿设静止部1，液体/气体通道21穿设运动部2。
进一步地，运动部2能够在液体/气体通道中21的液压/气压的作用下保持远离静止部1，从而密封进液/进气口41。驱动部3能够向运动部2提供驱动力，以使得运动部2克服液体/气体通道21中的液压/气压以靠近静止部1。
继续参照图4和5，静止部1具有能够至少部分地容纳运动部2的腔室，腔室内壁上形成凸缘12。运动部2上设置有弹性元件23，弹性元件23的一端抵靠于凸缘12，弹性元件23的另一端抵靠于运动部2，以使得运动部2在弹性元件23的弹力作用下保持远离静止部1。因此，驱动部3能够向运动部2提供驱动力，以使得运动部2克服液体/气体通道21中的液压/气压和/或弹性元件23的弹力以靠近静止部1。
进一步地，运动部2在密封端22处形成凸台24，弹性元件23抵靠于运动部2的一端抵靠在凸台24上，且弹性元件23保持压缩状态。
在本实施例中，弹性元件可以采用弹簧，特别是可以采用塔簧。
本领域技术人员应当能够理解，当进入电磁阀的液体/气体压力过大时，为了防止外部管路爆裂，还可以将出液/出气口42所在的管路作为进液/进气管路(即出液/出气口42被当做进液/进气口使用)，将静止部1和运动部2上的进液/进气通道11和液体/气体通道21作为出液/出气管路。换句话说，液体/气体在整个电磁阀中反向流动。由此，当流入电磁阀的液体/气体的压力持续增大到可以克服弹性元件23施加在运动部2的弹力时，运动部2自动地离开进液/进气口41(此时作为出液/出气口使用)，电磁阀中的液体/气体流动通道被连通，有效地防止了外部管路中液压/气压过大而爆裂。
进一步地，在本实施例中，静止部1包括具有进液/进气通道11的静金属芯1a以及固定地套设于静金属芯1a上的金属套1b，上述的腔室设置于金属套1b上，静金属芯1a的磁导率大于金属套1b的磁导率。
本领域技术人员应当能够理解，静金属芯1a和金属套1b的连接方式可以为过盈压入，也可以是焊接、粘接或者冲压等方式或者多种方式的组 合。
进一步地，静金属芯1a与金属套1b之间设有第一密封圈13(例如O型密封圈)，第一密封圈13容纳于静金属芯1a与金属套1b相邻的外侧壁上开设有的凹槽内。若静金属芯1a和金属套1b采用上述的焊接方式，可以省略该第一密封圈13。
进一步地，静金属芯1a和金属套1b采用铁或不锈钢制成。比如10#钢或SUS 430、SUS304、SUS303不锈钢等。需要特别注意的是，为了防止静金属芯1a和金属套1b生锈，可以在静金属芯1a和金属套1b接触液体的表面做防腐蚀处理，以延长电磁阀的使用寿命。
运动部2为动金属芯，动金属芯也可以采用铁或不锈钢制成，并且也可以在动金属芯接触液体的表面做防腐蚀处理，以延长电磁阀的使用寿命。如图6所示，驱动部3包括线圈31，当电流通过线圈31时，静金属芯1a产生磁力，吸附动金属芯靠近静金属芯1a。在图示的实施例中，动金属芯的截面形状为六角形状，有利于减小动金属芯与金属套1b的内壁的接触面积，从而减小它们之间的摩擦力，便于动金属芯在金属套1b内滑动。当然，动金属芯的截面也可以是圆柱形、正方形或者其他形状。线圈31可以采用漆包线。
进一步地，驱动部3还包括套设于金属套1b上的线圈骨架32(截面类似“工字型”)，线圈31缠绕于线圈骨架32上，以及设置于线圈骨架32上的磁轭组件33，磁轭组件33围设于线圈骨架32，磁轭组件33呈环形。在本实施例中，磁轭组件33包相对地设置于述线圈骨架32上的磁轭上部331和磁轭下部332，磁轭上部331和磁轭下部332相互固定连接，线圈31位于磁轭上部331和磁轭下部332之间。
在本实施例中，磁轭下部332的相对两端向上弯折以形成磁轭侧部，并以该磁轭侧部和磁轭上部331连接，从而使得整个磁轭组件33呈环形。但本领域技术人员应当能够理解，这仅是一个示例，并非本发明对形成环形的磁轭组件33方式的限定。
进一步地，驱动部3包括包裹于线圈骨架32上的绝缘壳体34，磁轭组件33、线圈31密封于绝缘壳体34内，绝缘壳体34上形成有与线圈31电连接的接线端子。
进一步地，绝缘壳体34上形成有安装挂钩35，以便于驱动部3和外部设备连接，保证整个电磁阀安装稳固。
在另外的实施例中，电磁阀还包括了用于将静止部1锁定于连通管4的进液/进气口41处的锁止件5。
进一步地，进液/进气口41设于一柱状体43上，柱状体43具有外螺纹。锁止件5为具有内螺纹的旋盖，锁止件5能够通过内螺纹与上述外螺纹的配合锁止于柱状体43上。
进一步地，进液/进气口41和锁止件5(旋盖)之间设有第二密封圈44(例如O型密封圈)。
更进一步地，第二密封圈44夹设在锁止件5(旋盖)、柱状体43以及静止部1(金属套1b)配合形成的容纳空间内。
如图4和图7所示，连通管4的出液/出气口42的数量为多个，运动部2的密封端22能够同时断开或连通出液/出气口42与进液/进气口41。
更具体地，连通管4在进液/进气口41处设置有多个过渡流道45，每个出液/出气口42和相应的过渡流道45连通以形成出液/出气通道。多个过渡流道45的液体/气体入口位于同一平面上，运动部2的密封端22能够通过同时密封或打开多个过渡流道45的液体/气体入口，从而使得过渡流道45的液体/气体入口与多个出液/出气通道同时断开(如图5所示)或连通(如图4所示)。
在本实施例中，连通管4包括沿第一方向设置的具有进液/进气口41的第一管路4a，垂直于第一方向设置的具有出液/出气口42的第二管路4b和第三管路4c，所述第二管路4b和第三管路4c分别与第一管路4a连通。
基于上述结构，本领域技术人员应当能够理解，本发明并不限定连通管4包括的出口数量，一个出口、两个出口或者更多的出口都是根据需要选择的。
请参见图8和图9，本发明提供另一种不限流向的电磁阀。本实施例提供的电磁阀包括静止部221、运动部222、驱动部223以及连通管224。运动部222设有第一液体/气体通道2221，运动部222能够相对静止部221运动。驱动部223用于驱动运动部222靠近静止部221。连通管224具有第二液体/气体通道224a。其中，运动部222远离静止部221的一端形成密封端2222，当运动部222保持远离静止部221时，运动部222凭借密封端2222密封第二液体/气体通道224a的端口2241；当运动部222在驱动部223的 驱动力作用下靠近静止部221时，第一液体/气体通道2221和第二液体/气体通道连通224a。
进一步地，第一液体/气体通道2221穿设于运动部2中。
进一步地，第一液体/气体通道2221与静止部1中设有的第三液体/气体通道相连通2211。
进一步地，第二液体/气体通道224a为进液/进气通道及/或出液/出气通道中的一种，第三液体/气体通道2211为进液/进气通道及/或出液/出气通道中的另一种。
需要说明的是，上述图示中的电磁阀仅为本发明的一实施方式，本领域技术人员在不脱离本发明的基本原理和精神的基础上，得到的其他所述实施方式仍然落入本发明的保护范围。例如，本领域技术人员可以结合图1～图7得到其他实施方式仍然落入本发明的保护范围。
如图10所示，本实施例提供了一种可移动平台，包括上述的电磁阀以及喷嘴6。电磁阀用于控制可移动平台是否喷出液体/气体。当电磁阀控制可移动平台不喷出液体/气体时，电磁阀能够密封连通管4的进液/进气口41，并防止液体/气体从喷嘴6泄露；当电磁阀控制可移动平台喷出液体/气体时，喷嘴6与连通管4的出液/出气口42连通，以使得液体或气体经由所述电磁阀后从喷嘴6喷出。
进一步地，可移动平台还包括储液箱7和水泵(图未示)。所述水泵用于将所述储液箱7中的液体泵出，再经由所述电磁阀后从所述喷嘴6喷出。
在本实施例中，上述的可移动平台可以是无人机，特别是农用无人机。

  29. 根据权利要求28所述的可移动平台，其特征在于，包括：
    储液箱和水泵；
    所述水泵用于将所述储液箱中的液体泵出，再经由所述电磁阀后从所述喷嘴喷出。
  30. 根据权利要求29所述的可移动平台，其特征在于：
    所述可移动平台是无人机。
  31. 根据权利要求30所述的可移动平台，其特征在于：
    所述可移动平台是农用无人机。
  32. 一种电磁阀，其特征在于，包括：
    静止部；
    运动部，设有第一液体/气体通道，所述运动部能够相对所述静止部运动；
    驱动部，用于驱动所述运动部靠近所述静止部；以及
    连通管，具有第二液体/气体通道；
    其中，所述运动部远离所述静止部的一端形成密封端，当所述运动部 保持远离所述静止部时，所述运动部凭借所述密封端密封所述第二液体/气体通道的端口；当所述运动部在所述驱动部的驱动力作用下靠近所述静止部时，所述第一液体/气体通道和所述第二液体/气体通道连通。
  33. 根据权利要求32所述的电磁阀，其特征在于，所述第一液体/气体通道穿设于所述运动部中。
  34. 根据权利要求32所述的电磁阀，其特征在于，所述第一液体/气体通道与所述静止部中设有的第三液体/气体通道相连通。
  35. 根据权利要求34所述的电磁阀，其特征在于，所述第二液体/气体通道为进液/进气通道及/或出液/出气通道中的一种，所述第三液体/气体通道为进液/进气通道及/或出液/出气通道中的另一种。
