现在将参考附图更全面地描述示例实施例。然而，示例实施例能够以多种形式实施，且不应被理解为限于在此阐述的实施例；相反，提供这些实施例使得本公开将全面和完整，并将示例实施例的构思全面地传达给本领域的技术人员。图中相同的附图标记表示相同或类似的结构，因而将省略它们的详细描述。
参阅图1，其代表性地示出了本公开提出的电磁阀的剖视图。在该示例性实施方式中，本公开提出的电磁阀是以应用于空调系统的压缩机回流方案为例进行说明的。本领域技术人员容易理解的是，为将本公开的相关设计应用于其他类型的空调系统或其他设备中，而对下述的具体实施方式做出多种改型、添加、替代、删除或其他变化，这些变化仍在本公开提出的电磁阀的原理的范围内。
如图1所示，在本实施方式中，本公开提出的电磁阀包含阀体110以及芯铁120。配合参阅图2，图2中代表性地示出了图1示出的A部分的放大图。以下将结合上述附图，对本公开提出的电磁阀的各主要组成部分的结构、连接方式和功能关系进行详细说明。
如图1和图2所示，在本实施方式中，该阀体110具有阀腔、进口1101及出口1102，该进口1101和该出口1102分别连通于该阀腔。该芯铁120设置有通道1201，该通道1201的一端连通于阀腔，通道1201的另一端由密封件121封闭。通道1201与阀体110之间连接有复位件122，该复位件122用以使芯铁120可复位地通过该密封件121封闭于出口1102。在此基础上，电磁阀具有第一节流孔131。该第一节流孔131设置于密封件121，芯铁120封闭于出口1102时，第一节流孔131的一端连通于出口1102，第一节流孔131的另一端通过通道1201连通于阀腔，从而使得电磁阀在芯铁120关闭时仍具有一定流量。据此，当电磁阀应用于空调系统的压缩机回油方案中时，压缩机排出的制冷剂及润滑油经油分离器分离后的润滑油，可以该电磁阀回流到压缩机的吸气口。在正常运行时，润滑油 通过电磁阀节流孔回流到压缩机，当压缩机排出润滑油较多时，电磁阀打开，以确保润滑油及时回流到压缩机。通过上述结构设计，空调系统利用本公开提出的电磁阀，无需设置并联的毛细管和电磁阀，能够大幅降低设备成本，同时简化系统结构。
可选地，如图1和图2所示，在本实施方式中，电磁阀包含一个第一节流孔131，第一节流孔131设置于密封件121的中心位置，且第一节流孔131沿通道1201的中心线方向延伸。据此，本公开能够保证润滑油经由通道1201和第一节流孔131流至出口1102。
可选地，如图1和图2所示，在本实施方式中，密封件121可以大致呈柱状结构，即密封件121的截面可以大致呈矩形。在此基础上，密封件121可以采用居中的方式设置在芯铁120上，即密封件121的中心线可以与通道1201的中心线大致重合。据此，当第一节流孔131沿通道1201的中心线方向延伸时，亦是大致沿密封件121的中心线方向延伸。
可选地，如图1和图2所示，在本实施方式中，阀体110可以包含导管部111以及本体部112。具体而言，该导管部111可知大致呈筒状结构，导管部111的一端筒口封闭，芯铁120设置于导管部111的筒腔1111内，且芯铁120与导管部111的筒壁之间具有间隙G。该本体部112设置于导管部111的另一端筒口，本体部112具有内腔1121，该内腔1121与导管部111的筒腔1111连通，从而共同定义出电磁阀的阀腔，在此基础上，电磁阀的进口1101和出口1102可以分别设置于本体部112。
进一步地，如图1所示，基于阀体110包含导管部111呈筒状结构且一端筒口封闭的结构设计，在本实施方式中，导管部111的筒腔1111内可以设置有吸引子部件113，该吸引子部件113封闭导管部111的一端筒口。在此基础上，复位件122可以连接于吸引子部件113与芯铁120的通道1201之间。
进一步地，如图1所示，基于导管部111的筒腔1111内设置有吸引子部件113的结构设计，在本实施方式中，通道1201内可以设置有台阶结构1202，复位件122一端连接于该台阶结构1202的台阶面，复位件122的另一端伸出通道1201并连接于吸引子部件113。
可选地，如图1所示，在本实施方式中，复位件122可以包含复位弹簧。
可选地，如图2所示，在本实施方式中，芯铁120可以设置有平衡孔1202，该平衡孔1202大致沿芯铁120的径向延伸，且平衡孔1202与芯铁120的通道1201连通。
基于上述对本公开提出的电磁阀的第一实施方式的详细说明，以下将对电磁阀在第一实施方式中的工作原理进行大致说明。
当芯铁120关闭时，即当芯铁120通过密封件121封闭于电磁阀的出口1102时，经 由分离器分离的润滑油仍能够经由“进口1101→阀腔(内腔1121→平衡孔1202→筒腔1111)→通道1201→第一节流孔131→出口1102”的路径流经电磁阀，从而使得电磁阀在关闭状态下具有一定流量。
当经由分离器分离的润滑油较多时，电磁阀开启，芯铁120打开，即芯铁120与出口1102脱离，润滑油能够经由“进口1101→阀腔(内腔1121)→出口1102”的路径流经电磁阀，当然同时也能够经由“进口1101→阀腔(内腔1121→筒腔1111)→通道1201→第一节流孔131→出口1102”的路径流经电磁阀，从而满足较大流量的流通。
电磁阀实施方式二
基于上述对本公开提出的电磁阀的第一实施方式的详细说明，以下将结合图3和图4，对本公开提出的电磁阀的第二实施方式进行说明。在该第二实施方式中，本公开提出的电磁阀采用与上述第一实施方式大致相同的结构设计，以下将对电磁阀在该第二实施方式的主要区别进行说明。
如图3所示，其代表性地示出了本公开提出的电磁阀在第二实施方式中的剖视图，图4代表性地示出了图3示出的B部分的放大图。
如图3和图4所示，在本实施方式中，密封件121大致呈球型结构。在此基础上，本公开提出的电磁阀具有第二节流孔132，且不具有第一节流孔131。具体而言，该第二节流孔132设置于阀体110，且第二节流孔132连通于阀腔与出口1102。据此，由于呈球型结构的密封件121在芯铁120动作过程中容易产生旋转，不再密封件121上设置第一节流孔131，能够避免第一节流孔131因密封件121的旋转而无法连通通道1201与出口1102。在阀体110上设置第二节流孔132能够将阀腔与出口1102直接连通，亦可保证本公开提出的电磁阀在关闭状态下仍具有一定流量。
可选地，如图3和图4所示，在本实施方式中，阀体110可以具有本体部112，该本体部112的内腔1121定义阀腔的一部分，且电磁阀的进口1101和出口1102分别设置于本体部112。在此基础上，第二节流孔132可以设置于本体部112，且第二节流孔132连通于内腔1121与出口1102。
需说明的是，在其他实施方式中，当本公开提出的电磁阀仅设置第二节流孔132时，电磁阀的密封件121亦可呈其他结构，例如与第一实施方式中的电磁阀的密封件121相同的结构，并不以本实施方式为限。
基于上述对本公开提出的电磁阀的第二实施方式的详细说明，以下将对电磁阀在第二实施方式中的工作原理进行大致说明。
当芯铁120关闭时，即当芯铁120通过密封件121封闭于电磁阀的出口1102时，经由分离器分离的润滑油仍能够经由“进口1101→阀腔(内腔1121)→第二节流孔132→出口1102”的路径流经电磁阀，从而使得电磁阀在关闭状态下具有一定流量。
当经由分离器分离的润滑油较多时，电磁阀开启，芯铁120打开，即芯铁120与出口1102脱离，润滑油能够经由“进口1101→阀腔(内腔1121)→出口1102”的路径流经电磁阀，当然同时也能够经由“进口1101→阀腔(内腔1121)→第二节流孔132→出口1102”的路径流经电磁阀，从而满足较大流量的流通。
电磁阀实施方式三
基于上述对本公开提出的电磁阀的第一实施方式和第二实施方式的详细说明，以下将结合图5，对本公开提出的电磁阀的第三实施方式进行说明。在该第三实施方式中，本公开提出的电磁阀采用与上述第一实施方式和第二实施方式大致相同的结构设计，以下将对电磁阀在该第三实施方式的主要区别进行说明。
如图5所示，其代表性地示出了本公开提出的电磁阀在第三实施方式中的部分放大图，据此可以参考图2相对应图1中的A部分放大区域。
如图5所示，在本实施方式中，本公开提出的电磁阀具有第一节流孔131和第二节流孔132。具体而言，第一节流孔131设置于密封件121，且第一节流孔131连通于通道1201与出口1102。第二节流孔132设置于阀体110，且第二节流孔132连通于阀腔与出口1102。通过上述结构设计，本公开提出的电磁阀利用第一节流孔131和第二节流孔132，在电磁阀关闭状态下仍能具有一定流量。
基于上述对本公开提出的电磁阀的第三实施方式的详细说明，以下将对电磁阀在第三实施方式中的工作原理进行大致说明。
当芯铁120关闭时，即当芯铁120通过密封件121封闭于电磁阀的出口1102时，经由分离器分离的润滑油仍能够经由“进口1101→阀腔(内腔1121→平衡孔1202→筒腔1111)→通道1201→第一节流孔131→出口1102”和“进口1101→阀腔(内腔1121)→第二节流孔132→出口1102”的路径流经电磁阀，从而使得电磁阀在关闭状态下具有一定流量。
当经由分离器分离的润滑油较多时，电磁阀开启，芯铁120打开，即芯铁120与出口1102脱离，润滑油能够经由“进口1101→阀腔(内腔1121)→出口1102”的路径流经电磁阀，当然同时也能够经由“进口1101→阀腔(内腔1121→筒腔1111)→通道1201→第一节流孔131→出口1102”和“进口1101→阀腔(内腔1121)→第二节流孔132→出口 1102”的路径流经电磁阀，从而满足较大流量的流通。
电磁阀实施方式四
基于上述对本公开提出的电磁阀的第三实施方式的详细说明，以下将结合图6，对本公开提出的电磁阀的第四实施方式进行说明。在该第四实施方式中，本公开提出的电磁阀采用与上述第三实施方式大致相同的结构设计，以下将对电磁阀在该第四实施方式的主要区别进行说明。
如图6所示，其代表性地示出了本公开提出的电磁阀在第四实施方式中的部分放大图，据此可以参考图2相对应图1中的A部分放大区域。
如图6所示，在本实施方式中，本公开提出的电磁阀具有三个第一节流孔131和两个第二节流孔132。具体而言，三个第一节流孔131设置于密封件121并间隔布置，且第一节流孔131连通于通道1201与出口1102。两个第二节流孔132设置于阀体110并间隔布置，且第二节流孔132连通于阀腔与出口1102。通过上述结构设计，本公开提出的电磁阀利用三个第一节流孔131和两个第二节流孔132，在电磁阀关闭状态下仍能具有一定流量。
需说明的是，在其他实施方式中，当本公开提出的电磁阀仅具有第一节流孔131时，第一节流孔131的数量可以为一个，亦可为两个以上。当本公开提出的电磁阀仅具有第二节流孔132时，第二节流孔132的数量可以为一个，亦可为两个以上。当本公开提出的电磁阀同时具有第一节流孔131和第二节流孔132时，第一节流孔131的数量可以为一个，亦可为两个以上，第二节流孔132的数量可以为一个，亦可为两个以上。另外，电磁阀同时具有第一节流孔131和第二节流孔132时，第一节流孔131与第二节流孔132的数量可以但不限于相同。
在此应注意，附图中示出而且在本说明书中描述的电磁阀仅仅是能够采用本公开原理的许多种电磁阀中的几个示例。应当清楚地理解，本公开的原理绝非仅限于附图中示出或本说明书中描述的电磁阀的任何细节或任何部件。
综上所述，本公开提出的电磁阀，通过设置第一节流孔和/或第二节流孔，使得，电磁阀在芯铁封闭出口时仍然具有一定的流量。据此，压缩机排出的制冷剂及润滑油经油分离器分离后的润滑油，可以该电磁阀回流到压缩机的吸气口。在正常运行时，润滑油通过电磁阀节流孔回流到压缩机，当压缩机排出润滑油较多时，电磁阀打开，以确保润滑油及时回流到压缩机。通过上述结构设计，空调系统利用本公开提出的电磁阀，无需设置并联的毛细管和电磁阀，能够大幅降低设备成本，同时简化系统结构。
基于上述对本公开提出的电磁阀的几个示例性实施方式的详细说明，以下将结合图7，对本公开提出的空调系统的一示例性实施方式进行说明。

如图7所示，在本实施方式中，本公开提出的空调系统包含压缩机200以及油分离器300。具体而言，该压缩机200具有排油口及吸气口，该油分离器300具有进油口及出油口，该排油口连通于该进油口。在此基础上，空调系统还包含本公开提出的并在上述实施方式中详细说明的电磁阀100，电磁阀100的进口通过第一管路410连通于出油口，电磁阀100的出口通过第二管路420连通于吸气口。据此，通过采用本公开提出的电磁阀100，在正常运行时，润滑油通过电磁阀100节流孔回流到压缩机200，当压缩机200排出润滑油较多时，电磁阀100打开，以确保润滑油及时回流到压缩机200。通过上述结构设计，本公开提出的空调系统无需设置并联的毛细管和电磁阀100，能够大幅降低设备成本，同时简化系统管路，保护电磁阀100及空调系统。
在此应注意，附图中示出而且在本说明书中描述的空调系统仅仅是能够采用本公开原理的许多种空调系统中的几个示例。应当清楚地理解，本公开的原理绝非仅限于附图中示出或本说明书中描述的空调系统的任何细节或任何部件。
综上所述，本公开提出的空调系统，通过采用本公开提出的电磁阀，在正常运行时，润滑油通过电磁阀节流孔回流到压缩机，当压缩机排出润滑油较多时，电磁阀打开，以确保润滑油及时回流到压缩机。通过上述结构设计，本公开提出的空调系统无需设置并联的毛细管和电磁阀，能够大幅降低设备成本，同时简化系统结构。
虽然已参照几个典型实施例描述了本公开，但应当理解，所用的术语是说明和示例性、而非限制性的术语。由于本公开能够以多种形式具体实施而不脱离公开的精神或实质，所以应当理解，上述实施例不限于任何前述的细节，而应在随附权利要求所限定的精神和范围内广泛地解释，因此落入权利要求或其等效范围内的全部变化和改型都应为随附权利要求所涵盖。
