现有技术中的电磁阀，通常包括阀体和盖板，阀体内部具有空腔，盖板与阀体通过焊接(例如：钎焊)的方式来连接，并有效密封阀体内部的空腔；在焊接过程中，因盖板与阀体的相对位置、重力等外部因素的影响，焊料在焊接时会同时向焊缝及焊缝的反方向流动，本应填充在焊缝处的焊料因反方向的流动会导致焊料对于焊缝处的填充不足，导致盖板和阀体之间的焊接不充分，进而可能出现空腔发生泄漏等问题，同时，反方向流动的焊料在凝固后会在盖板的表面形成不规则结构，影响电磁阀整体外观的美观和一致性。
现有技术中的电磁阀，其盖板与阀体的焊接端通常会进行常规倒角设计，形成一些小型凹槽，这些小型凹槽中的至少一部分在焊接时会容纳一部分焊料，以保证盖板在阀体上焊接固定的效果，但是上述小型凹槽仍然无法解决上述焊料在焊接时向焊缝反方向流动的问题，进而导致焊料对于小型凹槽的填充依然存在填充不足的问题。

本申请通过在盖板30上设置焊料阻挡结构32，焊料阻挡结构32在焊接时可以有效止挡焊接位置311上的焊料50向背离焊接位置311的方向流动，使得焊料50集中在焊接位置311附近，避免了本应填充在焊缝处的焊料50因反方向的流动而导致焊料50对于焊缝处填充不足的问题，进而保证了盖板30和阀体10之间的充分焊接，避免了空腔11发生泄漏等问题；同时，焊料阻挡结构32也有效阻止了反向流动的焊料50在盖板30的表面形成不规则结构，进而提高了电磁阀整体外观的美观和一致性。
如图2、图3和图4所示，在本申请的实施例一中，焊料阻挡结构32为凸柱结构321，凸柱结构321在轴向上的一端固定设置在板体31上，凸柱结构321在周向上的曲面止挡背离焊接位置311流动的焊料50。通过设置焊料阻挡结构32为凸柱结构321，既保证了焊料阻挡结构32易于加工成型，又保证了凸柱结构321在周向上对反向流动的焊料50的可靠阻隔。
如图2所示，凸柱结构321在轴向上的长度A的数值范围为0.2～0.5mm。这样设置，既保证了凸柱结构321对反向流动的焊料50的止挡效果满足实际要求，又使得凸柱结构321易于加工；在实际使用时，可以在板体31上通过常规的切削加工步骤，形成凸柱结构321，更加简单便捷。
可选地，如图5和图6所示，在本申请的实施例二中，凸柱结构321的中部开设有通孔322，通孔322的轴线与凸柱结构321轴线共线，开设有通孔322的凸柱结构321为环状结构。通过设置通孔322，使得凸柱结构321整体结构轻量化。
如图2所示，在焊接位置311和焊料阻挡结构32之间，板体31还具有焊料缓冲区40，焊料缓冲区40引导背离焊接位置311流动的焊料50运动。通过设置焊料缓冲区40，实现了对于反向流动的焊料50的有效容纳和引导，进而有效提高了整体焊接的质量。
如图2至图8所示，板体31在焊接位置311设置有倒角环槽312，以容纳焊料50；板体31位于焊料阻挡结构32和倒角环槽312之间表面为连接环面41，连接环面41形成焊料缓冲区40。通过设置倒角环槽312，进一步限位和容纳焊料50，进而提高了焊接质量，保证了盖板30和阀体10之间的充分焊接，避免了空腔11发生泄漏等问题；通过设置连接环面41，在焊料50凝固后，进一步提高了电磁阀整体外观的美观和一致性。
具体地，连接环面41的圆环宽度范围为1～3.5mm。这样设置，既保证了连接环面41易于加工成型，又保证了连接环面41对于反向流动的焊料50的容纳和引导效果。
可选地，如图7所示，在本申请的实施例三中，连接环面41为斜面，斜面与倒角环槽312的连接处为第一边，斜面与焊料阻挡结构32的连接边为第二边，在盖板30的轴向上，第二 边所在平面比第一边所在平面更靠近焊料阻挡结构32远离板体31的端面(即斜面的倾斜方向与焊料50自发流动的方向相适配)。这样设置，保证了反向流动的焊料50能够沿斜面顺畅流动，并且在焊料50凝固后，在一定程度上保证了焊接位置311的外观平整度。
可选地，如图8所示，在本申请的实施例四中，连接环面41为凹曲面，凹曲面中部形成容纳腔，以容纳焊料50。通过设置连接环面41为凹曲面，在结构上保证了对于反向流动的焊料50的较大容纳空间，并且在焊料50凝固后，在一定程度上保证了焊接位置311的外观平整度和美观程度。
具体地，盖板30为一体结构。这样设置，便于盖板30加工成型。
如图1所示，装配口111内具有止挡台阶112，板体31背离焊接位置311的端面和止挡台阶112的底面止挡配合，装配口111的侧壁端部为缩口段113，缩口段113和板体31铆接，缩口段113的内表面通过焊料50和板体31焊接。通过设置止挡台阶112，实现了对于板体31的可靠定位；通过设置缩口段113和板体31铆接，进一步提高板体31在阀体10上的安装强度，并且更加便于后续板体31在阀体10上的焊接工作。
如图1所示，阀体10的内部还具有分别与空腔11连通的第一接口60、第二接口70和第一流道80；活动组件20用于控制第一接口60和第二接口70的连通或关闭；第二接口70与空腔11的连接端处设有第二流道90；电磁阀还包括阀芯组件100，阀芯组件100设置在阀体10上，用于控制第一流道80和第二流道90的连通或关闭。这样设置，便于活动组件20在较大压差的条件下(例如：第一接口60和第二接口70之间的压差较大)，能够灵活开闭(例如：通过调节阀芯组件100控制第一流道80和第二流道90的连通，平衡空腔11内的压力，以便于电磁阀的开闭)。
综上所述，本申请提供了一种电磁阀，本申请通过在盖板30上设置焊料阻挡结构32，焊料阻挡结构32在焊接时可以有效止挡焊接位置311上的焊料50向背离焊接位置311的方向流动，使得焊料50集中在焊接位置311附近，避免了本应填充在焊缝处的焊料50因反方向的流动而导致焊料50对于焊缝处填充不足的问题，进而保证了盖板30和阀体10之间的充分焊接，避免了空腔11发生泄漏等问题；同时，焊料阻挡结构32也有效阻止了反向流动的焊料50在盖板30的表面形成不规则结构，进而提高了电磁阀整体外观的美观和一致性。
