在本公开的描述中，“多个”的含义是两个或两个以上。
下面参考附图描述根据本公开实施例的电磁阀1。
如图1-图5所示，根据本公开实施例的电磁阀1包括阀体100、阀芯200、静磁芯300和动磁芯400。
阀体100一体构造有磁芯安装部130，阀芯200可移动地设于阀体100内，用于控制电磁阀1的开闭。静磁芯300安装于磁芯安装部130，以与阀体100的相对位置固定。动磁芯400的至少一部分设于磁芯安装部130内，动磁芯400相对于阀体100可移动，以利用与静磁芯300之间的电磁力控制阀芯200的移动。
在一些实施例中，阀体100和阀芯200可以为不导磁的材质制成。其中，阀体100可以为不导磁的不锈钢材质制成。
根据本公开实施例的电磁阀1，通过将阀体100一体构造有磁芯安装部130，且静磁芯300安装于磁芯安装部130，以与阀体100的相对位置固定。动磁芯400的至少一部分设于磁芯安装部130内，动磁芯400相对于阀体100可移动。
通过设置磁芯安装部130，能够避免静磁芯300、阀体100和动磁芯400三者分离，且保证静磁芯300和阀体100的相对位置固定。动磁芯400和静磁芯300的相对运动范围也被阀体100限定。相对于相关技术中额外设置的电芯罩来定位动磁芯和静磁芯的电磁阀，由于本公开实施例的电磁阀1的阀体100和磁芯安装部130为一体构造成型，因此无需额外设置电芯罩，零件数量更少，并且，无需进行电芯罩和阀体100之间的装配，装配更简单且装配步骤更少。此外，阀体100和磁芯安装部130之间的相对位置也更为精准，加工精度更高。
另外，阀芯200可移动地设于阀体100内，用于控制电磁阀1的开闭，动磁芯400利用与静磁芯300之间的电磁力控制阀芯200的移动。由此，能够通过动磁芯400与静磁芯300之间的电磁力作用于阀芯200，以间接地实现电磁阀1切换至打开状态或关闭状态。
如此，根据本公开实施例的电磁阀1，电磁阀1具有零件数量少、装配简单、装配步骤少且加工精度高等优点。
根据本公开的一些具体实施例，如图1-图4所示，电磁阀1可以应用于空调系统中，阀体100的外周面可以设有螺纹160，阀体100可以通过螺纹160与空调系统中的管道连接，阀体100可以为不导磁的金属材质制成。
如此设置，电磁阀1装配于空调系统中的装配工艺简单可靠，便于后续维修拆换。而且，阀体100的外周面还设置定位槽150，密封圈800套设于阀体100，且位于定位槽150内，从而密封圈800能够密封阀体100和空调系统中的管道之间的间隙。
根据本公开的一些具体实施例，动磁芯400利用与静磁芯300之间的电磁力控制阀芯200移动，以控制电磁阀1打开。
具体地，如图1和图2所示，电磁阀1还包括第一弹性件600和第二弹性件700。第一弹性件600安装于磁芯安装部130内且位于动磁芯400和静磁芯300之间。第一弹性件600的两端分别止抵于动磁芯400和静磁芯300。例如，第一弹性件600在动磁芯400和静磁芯300之间被压缩。
其中，电磁阀1断电时，动磁芯400在第一弹性件600的弹力下推动阀芯200，以控制电磁阀1关闭。电磁阀1通电时，动磁芯400利用与静磁芯300之间的电磁力克服第一弹性件600的弹力，使第二弹性件700利用自身的弹力推动阀芯200，以控制电磁阀1打开。
在一些实施例中，第一弹性件600的弹力大于第二弹性件700的弹力、动磁芯400的重力以及阀芯200的重力三者之和。由此，无论电磁阀1处于什么样的摆放位置，在电磁阀1断电的情况下，第一弹性件600的弹力都能够推动阀芯200，以使电磁阀1稳定地保持在关闭状态。而且，在电磁阀1通电的情况下，动磁芯400和静磁芯300之间的电磁力能够驱动动磁芯400向远离阀芯200的方向移动(即向靠近静磁芯300的方向移动)，从而动磁芯400与阀芯200分离，阀芯200能够被第二弹性件700推动。此时，电磁阀1从关闭状态转变为打开状态。
根据本公开的一些具体实施例，动磁芯400利用与静磁芯300之间的电磁力控制阀芯200移动，以控制电磁阀1关闭。由此，动磁芯400利用与静磁芯300之间的电磁力能够控制电磁阀1从打开状态切换为关闭状态。
根据本公开的一些具体实施例，动磁芯400利用与静磁芯300之间的电磁力控制阀芯200移动，以控制电磁阀1打开以及关闭。例如，动磁芯400和阀芯200之间可以通过连杆等结构固定相对位置，以使动磁芯400和阀芯200之间可以同步移动。动磁芯400与静磁芯300之间可以设有第一弹性件600。
在电磁阀1通电的情况下，动磁芯400和静磁芯300之间的电磁力能够驱动动磁芯400向远离阀芯200的方向移动(即向靠近静磁芯300的方向移动)。此时，动磁芯400 带动阀芯200移动，以控制电磁阀1从关闭状态转变为打开状态。
在电磁阀1断电的情况下，第一弹性件600的弹力推动动磁芯400向靠近阀芯200的方向移动(即向远离静磁芯300的方向移动)，动磁芯400带动阀芯200移动，以控制电磁阀1从打开状态转变为关闭状态。
在本公开的一些实施例，如图1和图2所示，动磁芯400的朝向静磁芯300的一端设有第一凹槽410。静磁芯300的朝向动磁芯400的一端设有第二凹槽330。第一弹性件600的一端插入第一凹槽410且另一端插入第二凹槽330。
通过第一凹槽410和第二凹槽330的设置，能够固定第一弹性件600的上述一端和动磁芯400之间的相对位置，以及第一弹性件600的上述另一端和静磁芯300之间的相对位置。此外，第一弹性件600被压缩时，能够避免第一弹性件600的上述一端相对于动磁芯400滑动，以及第一弹性件600的上述另一端相对于静磁芯300滑动。第一弹性件600不会发生偏转或者扭转，从而第一弹性件600的弹力能够全部作用到动磁芯400和静磁芯300上，且第一弹性件600的弹力不会推动动磁芯400相对于磁芯安装腔131发生偏转，动磁芯400和磁芯安装腔131的腔壁之间滑动摩檫力更小。
在本公开的另一些实施例，动磁芯400的朝向静磁芯300的一端设有第一插柱(图中未示意)，静磁芯300的朝向动磁芯400的一端设有第二插柱(图中未示意)，第一弹性件600的一端套设于第一插柱且另一端套设于第二插柱。
由此，通过第一插柱和第二插柱的设置，能够固定第一弹性件600的上述一端和动磁芯400之间的相对位置，以及第一弹性件600的上述另一端和静磁芯300之间的相对位置。此外，第一弹性件600被压缩时，能够避免第一弹性件600的上述一端相对于动磁芯400滑动，以及第一弹性件600的上述另一端相对于静磁芯300滑动，从而第一弹性件600不会发生偏转或者扭转，第一弹性件600的弹力能够全部作用到动磁芯400和静磁芯300上。而且，第一弹性件600的弹力不会推动动磁芯400相对于磁芯安装腔131发生偏转，动磁芯400和磁芯安装腔131的腔壁之间滑动摩檫力更小。
根据本公开的一些具体实施例，如图1-图4所示，阀体100构造有向外凸出的套筒部110。磁芯安装部130形成于套筒部110，即，套筒部110构造成磁芯安装部130，套筒部110的远离阀体100的一端敞开。由此，便于实现阀体100和磁芯安装部130之间的一体化构造。而且，通过将套筒部110的远离阀体100的一端敞开，便于静磁芯300和动磁芯400安装在磁芯安装部130内。
如图1-图4所示，静磁芯300安装于套筒部110的敞开的一端并形成腔体340，动磁芯400位于腔体340中，动磁芯400可在腔体340内移动。
根据本公开的一些具体实施例，套筒部110的横截面的外轮廓所围绕的面积小于阀 体100的其余部分的横截面的外轮廓所围绕的面积。其中，套筒部110的横截面和阀体110的其余部分的横截面均为垂直于套筒部110的轴向的截面。这样，能够减小电磁阀1的体积，有利于电磁阀1的小型化设置，同时能够实现降低成本和减小重量的目的。
其中，套筒部110的横截面可以为圆环形。由此，在静磁芯300和动磁芯400安装于磁芯安装部130时，无需考虑相对于套筒部110的周向位置，装配难度进一步地降低。
根据本公开的一些具体实施例，如图1和图2所示，电磁阀1还包括阀座500。阀座500安装于阀体100，阀座500和磁芯安装部130分设于阀体100的相对两侧。阀座500和阀体100中的一个设有进口120，阀座500和阀体100中的另一个设有出口510。阀芯200通过控制进口120和出口510的通断，以控制电磁阀1的开闭。
在一些实施例中，阀体100的背向磁芯安装部130的一侧设有阀座安装口140，阀座500插入阀座安装口140。并且，阀体100上构造有多个进口120，多个进口120沿阀体100的周向间隔排布，阀座500上构造有沿其轴向贯通的出口510。其中，在电磁阀1断电的情况下，第一弹性件600的弹力推动动磁芯400向靠近阀芯200的方向移动，以使动磁芯400推动阀芯200向靠近出口510的方向移动，直至阀芯200封闭出口510，进口120和出口510之间不连通，此时，电磁阀1从打开状态转变为关闭状态。
在电磁阀1通电的情况下，动磁芯400和静磁芯300之间具有电磁力，动磁芯400在电磁力的驱动下向靠近静磁芯300的方向移动。此时，阀芯200在第二弹性件700的推动下向远离出口510的方向移动，出口510和阀芯200之间分离，进口120和出口510之间连通。此时，电磁阀1从关闭状态转变为打开状态。
第二弹性件700可以套设于阀芯200的朝向出口510的一端，第二弹性件700的两端分别止抵阀座500和阀芯200。在电磁阀1处于关闭状态时，第二弹性件700被压缩。
根据本公开的一些具体实施例，如图1-图3所示，磁芯安装部130构造有磁芯安装腔131。静磁芯300的至少一部分安装于磁芯安装腔131内，动磁芯400的至少一部分设于磁芯安装腔131内，且位于静磁芯300的朝向阀芯200的一侧。
如此设置，动磁芯400相对于静磁芯300更靠近阀芯200，便于动磁芯400控制阀芯200的移动。而且，阀芯200移动时不会与动磁芯400发生干涉，电磁阀1内零件布局更为方便。此外，静磁芯300的至少一部分和动磁芯400的至少一部分均设于磁芯安装腔131，能够减少静磁芯300、动磁芯400和磁芯安装部130三者整体的所占用的空间，有利于电磁阀1的小型化设置，并且静磁芯300、动磁芯400和磁芯安装部130三者之间的连接更为稳定可靠。
根据本公开的一些具体实施例，如图1-图3所示，磁芯安装腔131的背向阀芯200的一端敞开，静磁芯300的至少一部分插接于磁芯安装腔131内，且与磁芯安装腔131 过盈配合。
通过将磁芯安装腔131的背向阀芯200的一端敞开，可以便于将静磁芯300插入到磁芯安装腔131内，并且，静磁芯300的插入磁芯安装腔131内的部分和磁芯安装腔131过盈配合。由此，既能够固定静磁芯300和磁芯安装部130的相对位置，又便于后续静磁芯300和磁芯安装部130之间的拆卸维修，且电磁阀1的密封性好。
根据本公开的一些具体实施例，如图1-图3所示，静磁芯300包括插接段310和限位段320。
插接段310插接于磁芯安装腔131内且与磁芯安装腔131过盈配合。限位段320连接于插接段310的背向阀芯200的一端，限位段320的横截面积大于插接段310的横截面积。其中，限位段320的横截面和插接段310的横截面均为垂直于套筒部110的轴向的截面。限位段320位于磁芯安装腔131外且止抵于磁芯安装部130的远离阀芯200的一端。
通过设置插接段310，能够实现静磁芯300和磁芯安装部130之间的相对位置固定。此外，静磁芯300封闭了磁芯安装腔131的远离阀芯200的一端，避免动磁芯400从磁芯安装腔131的远离阀芯200的一端脱离磁芯安装部130，从而提高电磁阀1的密封性。而且，通过设置限位段320，能够避免静磁芯300全部插入磁芯安装腔131内，从而能够保证静磁芯300始终存在至少一部分位于磁芯安装腔131外，便于静磁芯300和阀体100之间的拆卸和维修。在一些实施例中，静磁芯300的外周面和磁芯安装部130的外周面可以位于同一曲面，以保证静磁芯300的外周面和磁芯安装部130的外周面之间平滑过渡。
根据本公开的一些具体实施例，如图1和图2所示，磁芯安装腔131的横截面的形状与动磁芯400的横截面的形状相适配。其中，动磁芯400和磁芯安装腔131之间可以间隙配合。由此，磁芯安装腔131的腔壁可以对动磁芯400的运动轨迹进行限定，无需额外设置对动磁芯400的运动轨迹进行限定的结构，零件数量更少，且结构更为简单可靠。
根据本公开的一些具体实施例，如图1和图2所示，动磁芯400的外周面与磁芯安装腔131的内周面配合，以限定动磁芯400沿磁芯安装腔131的轴向可移动。由此，复用了磁芯安装部130的内周面，无需额外设置限定动磁芯400移动路径的结构，减少了电磁阀1的零件数量，装配步骤少，装配难度低，并且有利于减小电磁阀1的体积。
根据本公开实施例的电磁阀1的其他构成以及操作对于本领域普通技术人员而言都是已知的，这里不再详细描述。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、 “示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本公开的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。
