本实施例中，设置第三组插针43可以使压装时线路板组件130受力更均匀。在其他实施例中，可以不设置第三组插针41，而是将第一组插针41、第二组插针42对称设置，也可以使压装线路板组件130时受力更均匀。在一实施例中，第三组插针41可以设置为接地，一方面从第三组插针43与第一壳体1固定的一端引出导线与定子组件110的磁轭连接，通过第三组插针43实现电路板组件130的接地端与定子组件110的磁轭的电连接，从而改善电动阀的电磁兼容性；另一方面，第三组插针43电连接线路板组件130和阀体150，将线路板组件130的接地层与阀体150连接，改善线路板组件130的电磁兼容性(Electro Magnetic Compatibility,EMC)干扰。

第一壳体1还设置有导向筋17，导向筋17设置于第三基台153和第一壳体1的侧壁之间，导向筋17与第一壳体1的侧壁一体成形，导向筋17的高度大于第三基台153的高度，线路板组件130设置有与导向筋17配合的缺口部137，导向筋17部分伸入所述缺口部137，本实施例中，导向筋17为一根，设置于第三基台153的内周，导向筋17设置于第三基台153和第一壳体的侧壁之间，导向筋17设置于第一壳体1的侧壁的内侧，这样不需要占第一壳体1的其他位置，有效利用第一壳体1的空间，导向筋17的相对高度大于第三基台153的高度，这样在基台16的上方就形成导向，定位更加准确；当然导向筋17也可以设置于第一基台151、第二基台152以及第四基台154的内侧；线路板组件130还设置有与导向筋17配合的缺口部137，导向筋17作为线路板组件130的安装向导，这样可以更好的方便线路板组件130装入时的定位与导向，提高装配效率，防止装配线路板组件130的误装。导向筋17的数量包括但不限于一个，可以根据需要适当增加。
参见图3、图10及图15，第一壳体1还包括定位筋14，定位筋14与第一壳体1的侧壁一体成形，定位筋14自第二侧壁112、第三侧壁113、第四侧壁114中的至少一个向第一壳体1的腔体3突起形成，线路板组件130设置有凹槽结构136，定位筋14部分伸入凹槽结构136设置，其中，定位筋14的高度大于基台15的高度，定位筋14根据设置位置不同分为第一定位筋141、第二定位筋142、第三定位筋 143，第一定位筋141设置于第二侧壁112内侧，第二定位筋142设置于第三侧壁113内侧，第三定位筋143设置于第四侧壁114内侧，定位筋14自侧壁向第一壳体1的腔体3突起形成，同时，线路板组件130设置有与第一定位筋141、第二定位筋142、第三定位筋143配合的所述凹槽结构136，在一实施例中也可以不设置凹槽结构136，线路板组件130的外缘与定位筋14抵接。线路板组件130安装后，线路板组件130与定位筋14抵接或间隙配合，这样可以更好的方便线路板组件130装入时的导向，保证插针4与线路板组件130的通孔对正设置，提高装配效率。
参见图1及图2，本实施例的电动阀100还设计了防水透气膜5和连通通道，盒体180的腔体3内的空气可以通过防水透气膜5以及连通通道排出腔体3，这样腔体3内的水蒸气也可以通过防水透气膜5和连通通道排出盒体180，而外部空气通过防水透气膜5进入腔体3时防水透气膜5可以将外部空气中的水蒸气隔离，这样外部水蒸气不能通过防水透气膜5进入腔体，可以使腔体3内部环境保持相对干燥，这样可以防止相对较高湿度的环境下，腔体3内的空气可能随着温度变化产生的凝露现象，可以防止凝露对线路板组件130等产生损坏，同时也可以保证盒体180内外压力的相对平衡，同时也可以隔离外部空气中的污染颗粒。
如图24所示，防水透气膜5包括固定连接部51和透气部52，固定连接部51环绕透气部52设置，固定连接部51与盒体180通过烫压、焊接或固定胶固定设置，这样气体不能够通过固定连接部51连通腔体3内外，只能通过透气部52连通腔体3内外，防止外部的水通过连接固定部51进入腔体3。
图16为盒体180的第一种实施方式本实施例中，盒体180包括第一壳体1和第二壳体2，第一壳体1和第二壳体2通过焊接固定连接，第一壳体1和第二壳体2的连接处密封设置，其中第一壳体1与以上第一壳体1相同，以下不再赘述，以下着重介绍第二壳体2。
结合图17，第二壳体2包括基板21，盒体180还包括防水透气膜5及连通通道，防水透气膜5与盒体180接触固定设置，腔体3与盒体180外部通过防水透气膜5和连通通道连通设置，防水透气膜5与第二壳体2固定设置，第二壳体2具有连通通道和第一凹部6，第一凹部6自腔体3向第二壳体2的外部凹陷形成，连通通道与第一凹部6连通设置，防水透气膜5容置于第一凹部6并固定设置，腔体3设置于防水透气膜的第一侧，连通通道设置于防水透气膜的第二侧，本实施例中，防水透气膜5固定于基板21的内侧，防水透气膜5与基板21的连接处密封设置，比如防水透气膜5与基板21可以通过烫压或焊接固定并密封，焊接方式可以为超声 波焊接，在一实施例中，防水透气膜5与基板21也可以通过固定胶固定并密封，在其他实施例中，防水透气膜5与基板21也可以采用其他方式固定；基板21具有连通通道，盒体180外部与腔体3内通过连通通道以及防水透气膜5保持气体连通，通过对防水透气膜5的空隙以及材料进行设计，这样的防水透气膜5可以保证外界的水不能通过防水透气膜5进入腔体3，同时外界与盒体180保持气体连通。本实施例中防水透气膜5由具有防水及透气功能的材料制成，本实施例中，防水透气膜5材料的主要成分为膨体聚四氟乙烯(EPTFE)，在一实施例中也可以采用其他具有相似功能的材料。
基板21包括外缘部201、第一限位筋202及溢料槽203，溢料槽203成形于外缘部201和第一限位筋202之间，第一壳体1和第二壳体2组装后，焊接筋12设置于溢料槽203内，第一限位筋202的外侧与第二壳体1侧壁的内侧抵接设置。
为方便描述，将基板21相对远离线路板组件130的一面称为第一面211，将基板21相对靠近线路板组件130的一面称为第二面212，防水透气膜5设置于第二面212。
参见图19和图20，基板21具有第一凹部6、第一面211及第二面212，第一凹部6自第二面212向第一面211凹陷形成，第一凹部6与连通通道连通设置，第二壳体2包括形成第一凹部6的第一底壁61、第二底壁62以及第一凹部侧壁63，第一底壁61和第二底壁62呈阶梯布置，第一凹部侧壁63设置于第一底壁61和第二底壁62之间，第二底壁62相对低于第一底壁61设置，连通通道成形于第二底壁62，防水透气膜5与第一底壁61固定设置，防水透气膜5将第一凹部6分隔为第一腔和第二腔，第二腔与连通通道连通，第一腔与腔体3连通。
在一实施例中，第一底壁61和第二底壁62间隔预设的距离，防水透气膜5与第一底壁61固定设置，第一底壁61所在的平面相对低于第一面211所在的平面，防水透气膜5部分与第一底壁61接触，防水透气膜5的四周与第一底壁61通过烫压或焊接固定并密封，焊接方式可以是超声波焊接，在一实施例中，防水透气膜5的四周与第一底壁61也可以通过固定胶固定并密封，保证防水性能和焊接部的强度和密封性，同时，第一底壁61所在的平面低于第一面211所在的平面，防水透气膜5固定后，经过烫压、焊接或固定胶连接后，与第二面212大致平齐或相对低于第二面212，可以防止防水透气膜5安装后突出于第二面212所在的平面，避免防水透气膜5被碰到而损坏，在一实施例中，还可以对防水透气膜的位置预先设定，简化确定安装位置的工序；在其他实施例中，防水透气膜5也可突出于 第二面212设置。
本实施例中，如图18-图20所示，连通通道包括第一部分，第一部分包括第一槽64、第二槽65、第三槽66及第四槽67，第一槽64、第二槽65、第三槽66及第四槽67自第二壳体2的外表面向内表面凹陷形成，第一槽64、第二槽65、第三槽66及第四槽67的结构相同并且围绕第一凹部6设置，第一槽64、第二槽65、第三槽66及第四槽67分别与第一凹部6连通。第一凹部6还包括遮挡部，遮挡部凸出第一凹部侧壁设置，遮挡部631的凸出高度大于连通通道的宽度，遮挡部631距离第二底壁62设定距离，在一实施例中，第二壳体2包括遮挡部631，遮挡部631自第一凹部侧壁63向第一凹部6形成的内腔凸起，该遮挡部631的凸起高度相对大于等于连通通道的第一槽64、第二槽65、第三槽66及第四槽67的宽度，该遮挡部631的最下端距离第二底壁62设定距离，这样设置的遮挡部631使得流通通道形成迷宫结构，保证流通的前提下，使得连通通道的间隙减小，减少外界的异物进入第一凹部6，可以减少异物直接触碰到防水透气膜5而使防水透气膜5受损；在一实施例中，第一槽64、第二槽65、第三槽66及第四槽67的槽孔的开口方向也可以与第一面211的夹角小于90或大于90，即第一槽64、第二槽65、第三槽66及第四槽67的延伸方向与第一面211不垂直设置，也可以减少异物直接触碰到防水透气膜5而使防水透气膜5受损。第一槽64、第二槽65、第三槽66及第四槽67的设置使连通通道留有足够的空间，保证空气的流通面积。通过设置防水透气膜5，盒体180的腔体3内的空气可以通过防水透气膜5排出盒体180，腔体3内的水蒸气通过防水透气膜5排出盒体180，而外部空气通过防水透气膜5进入腔体3时防水透气膜5可以将外部空气中的水蒸气隔离，这样外部水蒸气不能通过防水透气膜5进入腔体，可以使腔体3内部环境保持相对干燥，这样可以防止相对较高湿度的环境下，腔体3内的空气可能随着温度变化产生的凝露现象，可以防止凝露对线路板组件130等产生损坏，同时也可以保证盒体180内外压力的相对平衡。同时，也可以防止外部的液体分子和污染颗粒通过防水透气膜5进入腔体3，起到防水及防异物的作用，可以防止水和异物颗粒对线路板组件等产生损坏。在一实施例中，防水透气膜5也可以根据需要安装于第一壳体1。电动阀100应用时，为防止第一凹部6积水，第一凹部6可以相对倾斜设置或相对朝下设置。在另一种转述中，第一凹部具有第一凹部侧壁631，连通通道包括第一槽64、第二槽65、第三槽66及第四槽67，第一槽64、第二槽65、第三槽66及第四槽67由第一凹部侧壁631向外凹陷形成，第一槽64、第二槽65、第三槽66及第四槽67 不贯穿第一壳体1。
图21-图24为盒体的第二种实施方式，本实施方式与第一种实施方式相比较，主要区别在于第二壳体2，本实施例中，第二壳体2包括基板21及盖板22，基板21和盖板22分别成形并固定连接，连通通道设置于基板21和盖板22之间，盒体180设置有防水透气膜5，本实施例中防水透气膜5安装于基板21和盖板22之间，本实施例中，基板21和盖板22单独注塑成型，通过焊接或卡接固定连接，焊接方式可以是超声波焊接。
连通通道为基板21和盖板22的之间的间隙，盒体180外部与腔体3内通过连通通道以及防水透气膜5保持气体连通，通过对防水透气膜5的空隙以及材料进行设计，这样的防水透气膜5可以保证外界的水不能通过防水透气膜5进入盒体180，同时使外界与腔体3保持气体连通。本实施例中防水透气膜5由具有防水及透气功能的材料制成，本实施例中，防水透气膜5的材料的主要成分为膨体聚四氟乙烯(EPTFE)，当然也可以采用其他具有相似功能的材料。
参见图23，基板21包括第二凹部7和第一通孔部8，第二凹部7自第二壳体2的外部向腔体3凹陷形成，第二凹部7通过第一通孔部8与腔体3连通，第二凹部7包括第二凹部侧壁72和第二凹部底部71，第二凹部底部71和第二凹部侧壁72围绕第二凹部7内腔。第一通孔部8贯穿第二凹部7底部设置，防水透气膜5的固定连接部51与第二底壁62固定设置。第二壳体2还包括第一焊接部711，第一焊接部711自第二凹部底部71凸出设置，第一焊接部711与第二凹部侧壁72间隔设定距离，盖板22与基板21通过第一焊接部711焊接固定，第一焊接部711与第一通孔部8之间设有第一安装部712，防水透气膜5的四周与第一安装部712接触固定设置，在一实施例中，第二凹部底部71具有第一焊接部711，第一焊接部711凸出第二凹部底部71设置，第一焊接部711靠近第二凹部侧壁72并间隔设定距离。本实施例中，第一焊接部711为四个并间隔预定距离设置，防水透气膜5的四周与第一安装部712接触并通过烫压或焊接固定并密封，焊接方式可以是超声波焊接，在一实施例中，也可以通过固定胶固定并密封，第一焊接部711具有第一筋部2211，第一筋部2211突出第一焊接部711的顶部设置，第一筋部2211自顶部向下横截面积逐渐增大，第一筋部2211设置为与盖板22焊接，这样设置一方面有利于提高第一筋部2211与第一焊接部711的连接强度，另一方面第一筋部2211的顶部与盖板22接触，由于第一筋部2211的顶部的截面较小，达到第一筋部2211融化并焊接固定需要的能量越小，有利于节能，还有利于减小对盖板22和盒体 180的其他部分的影响。盖板22包括周侧部220，部分第二凹部侧壁72与周侧部220抵接配合或小间隙配合，部分第二凹部侧壁72与周侧部220之间形成连通通道；连通通道包括第一部分和第二部分，第二凹部侧壁72和周侧部220中至少一处具有凹槽，凹槽自第二凹部侧壁72和周侧部220中的至少一处凹陷形成，凹槽的长度小于盖板22的长度，且大于等于盖板22长度的三分之一，第二部分包括设置于盖板22的周侧部220并与凹槽配合的缺口2201，第二部分还包括盖板22与基板21通过所述缺口2201形成的间隙。第一部分包括第二凹部侧壁和周侧部中的至少一个通过凹槽形成间隙，其中，所述凹槽包括第五槽721、第六槽722、第七槽723及第八槽724，第五槽721、第六槽722、第七槽723及第八槽724自第二凹部侧壁72和周侧部220中的至少一处凹陷形成，第五槽721、第六槽722、第七槽723及第八槽724的长度小于盖板22的长度，且大于等于盖板22长度的三分之一，第二部分包括设置于盖板22的周侧部220，且与第五槽721、第六槽722、第七槽723及第八槽724配合的缺口2201。第一部分与第二部分连通设置，第五槽721、第六槽722、第七槽723及第八槽724的长度小于盖板的长度大于等于盖板长度的三分之一，这样保证流通通道的情况下，形成迷宫结构，防止异物直接触碰到防水透气膜5而使防水透气膜5受损。盖板22与第二凹部底部71连接的一端也可以设置焊接筋，焊接筋设置为与基板21连接。本实施例中，防水透气膜5的作用与第一种实施例中防水透气膜5的作用相同，在此不在赘述。电动阀100应用时，为防止第二凹部7积水，第二凹部7可以相对倾斜设置或相对朝下设置。本实施例中通过在基板21上形成第五槽721、第六槽722、第七槽723及第八槽724，在盖板22上形成缺口2201，这样形成连通通道，相对于将以上连通通道同时成形于基板21或盖板22上，使得基板21和盖板22成形容易，工装简单。
以上第一凹部6和第二凹部7是为了区别不同的实施方式，第一凹部6和第二凹部7为凹部。
