上述夹管阀相较于传统的夹管阀至少具有以下优点：
1、相较于圆形或椭圆形的流体通道，上述挤压通道在保证流量大致相同的前提下，还具有较厚的壁厚，故阀芯的主体的耐压及抗疲劳性能也更加突出，主体在经多次开关切换后依然还能保持较好的弹性。如此，可显著减缓阀芯老化的速度，使得上述夹管阀具有较长的使用寿命。
2、由于具有较厚的壁厚，故阀芯的主体的支撑性也更强。在夹管阀的使用过程中，不易因挤压通道内压力的变化而导致阀芯产生不必要的变形，从而保证流量控制的精准。
3、相较于圆形或椭圆形的流体通道，两个半壁结构相互抵接以使挤压通道闭合时，抵持件所需的行程较小，故上述夹管阀开关响应更及时。

请参阅图1至图4，本申请提供了一种夹管阀10及阀芯100。其中，夹管阀10包括阀芯100、阀体200及执行机构300。
请一并参阅图5，阀芯100包括能够弹性形变的主体110，主体110一般由橡胶等弹性材料成型。主体110为两端开口的中空结构，其两端形成有开口102。主体110形成有挤压通道101及受压部111，两端的开口102与挤压通道101连通。具体的，挤压通道101可以贯通主体110并由其中一端的开口102延伸至另一端的开口102。此外，挤压通道101也可仅为主体110内中空部分的一段，并与受压部111的位置对应。
通过作用于受压部111，能够使主体110变形并使挤压通道101闭合，从而将夹管阀10关闭。
阀体200用于支撑及收容阀芯100，一般为两端开口的筒状结构。阀体200具有进液口201及出液口202，阀芯100收容于阀体200且两端的开口102分别与进液口201及出液口202连通。流体，如电解液可经进液口201进入阀芯100，并在流过挤压通道101后再由出液口202流出。阀体200可以是一体成型的结构，也可由多个部分组装而成。譬如，在本实施例中，阀体200包括底座210、筒体230及上盖220，阀芯100可先定位于底座210，再由筒体230及上盖210进行封装。
执行机构300包括动力组件310及抵持件320，动力组件310能够提供动力以驱使抵持件320作用于受压部111，从而使挤压通道101闭合。抵持件320可以是杆状、块状等结构。动力组件310可以通过电动、气动或手动等方式驱使抵持件320动作，从而对夹管阀10的开关状态进行控制。
请再次参阅图2及图4，在本实施例中，阀体200上开设有进气口203，阀体200形成有围绕阀芯100的周向布设的气室204，通过进气口203向气室204通气或排气，能够使动力组件310驱动抵持件320作用于受压部111，以使挤压通道101闭合。
具体的，气室204形成于底座210、上盖220及筒体230之间。而且，底座210与筒体230间配置有密封圈240，以保证其实204的气密性。通过进气口203向气室204通气，使得气室204内的气压升高，从而驱动抵持件320撤销作用于受压部111的作用力。通过进气口203使气室204排气可使气室204内的气压降低，从而驱动抵持件320作用于受压部111。也就是说，夹管阀10的初始状态处于常闭状态，只有通过进气口101向气室204内通气，才能撤销作用于受压部111的作用力，进而将夹管阀10切换至打开状态。
抵持件320可以呈柱状，穿设于气室204的内侧壁并抵持于受压部111。通过使抵持件320相对于受压部111伸缩，便能够对受压部111施加外力的作用，进而关闭或打开夹管阀10。
进一步的，在本实施例中，动力组件310包括活塞311、导向套312及弹性件313。
活塞311安装于气室204内。当气室204充气后，可驱使活塞311沿气室204滑动。导向套312固定于活塞311的一端并绕阀芯100的周向布设，导向套312具有抵持斜面3121。弹性件313收容于气室204并作用于导向套312。具体的，弹性件313可以是压缩弹簧。抵持斜面3121在弹性件313的作用于与抵持件320相抵持，以使抵持件320作用于受压部111并使挤压通道101闭合。向气室204通气可驱使活塞311带动导向套312克服弹性件313的弹性力沿气室204滑动，抵持件320回退，以使挤压通道101打开。
以图2所示为例，初始状态下，导向套312在弹性件313的作用于抵持于气室204的下表面，抵持斜面3121则驱动抵持件320朝阀芯100伸出，从而使挤压通道101闭合以使夹管阀10处于关闭状态；当通过进气口203向气室204充气后，将驱使活塞311向上滑动。同时，抵持斜面3121逐渐解除对抵持件320的挤压，阀体110则复位并推动抵持件320回退，从而使夹管阀10切换至打开状态。
需要指出的是，在其他实施例中，夹管阀10的初始状态也可处于常开状态。此时，通过进气口203向气室204通气可使气室204内的气压升高，从而驱动抵持件320作用于受压部111，并将夹管阀10切换至关闭状态。
请一并参阅图6至图8，挤压通道101的内壁包括两个相对设置半壁结构112，在挤压通道101的径向截面内，具有相互垂直平分的第一轴a及第二轴b，第一轴a及第二轴b能够共同限定圆形或椭圆形，两个半壁结构112分布于第二轴b的两侧，且均位于上述与圆形或椭圆形的范围内。
具体的，第一轴a及第二轴b共同限定的圆形或椭圆形，指的是第一轴a及第二轴b作为直径的圆形，或作为长轴及短轴的椭圆形。需要指出的是，第一轴a及第二轴b均为虚拟的轴线，并非挤压通道101内实际存在的轮廓线。本实施例中，第二轴b的长度大于第一轴a的长度，故两者可共同限定一椭圆形c，且第二轴b及第一轴a分别作为椭圆形c的长轴及短轴。可见，相较于圆形或椭圆形的孔，挤压通道101在一定程度上向内收缩。
其中，外力作用于受压部111能够使两个半壁结构112靠拢，以使挤压通道101闭合。相较于圆形或椭圆形的流体通道，上述挤压通道101在保证流量大致相同的前提下，还具有较厚的壁厚，故阀芯100的主体110的支撑性更强。在夹管阀10的使用过程中，不易因挤压通道101内压力的变化而导致阀芯100产生不必要的变形，从而保证流量控制的精准。由于具有较厚的壁厚，阀芯100的主体110耐压及抗疲劳性能也更加突出，主体110在经多次开关切换后依然还能保持较好的弹性。而且，两个半壁结构112连接处的间距较小，挤压主体110时连接处的形变量较小，故不易因为频繁形变而疲劳，从而导致材料开裂损坏老化。由此可见，故上述夹管阀10还具有较长的使用寿命。
此外，相较于圆形或椭圆形的流体通道，两个半壁结构112相互抵接以使挤压通道101闭合时，抵持件320所需的行程较小，故上述夹管阀10开关响应更及时。
具体在本实施例中，第一轴a的长度小于第二轴b的长度。也就是说，挤压通道101更狭长，在保证流量大致相同的前提下，两个半壁结构112连接处之间的间距更小，故在使挤压通道101闭合时抵持件320所需的行程能够进一步减小。
具体在本实施例中，在挤压通道101的径向截面内，两个半壁结构112以长轴b为对称轴呈轴对称分布。如此，两个半壁结构112的对称性更好，在挤压通道101闭合时能够更加紧密的配合，从而保证夹管阀10关闭的可靠性。
请再次参阅图5，在本实施例中，主体110的中部向内收缩形成收缩部113，受压部111位于收缩部113，挤压通道101形成于主体110与收缩部113对应的位置。
也就是说，挤压通道101并未完全贯通主体110，而是仅形成于与收缩部113对应的位置。收缩部113的径向尺寸较小，在需要使挤压通道101闭合时，受压部111只需较小的形变即可，故可显著减小抵持件310的行程，从而进一步提升上述夹管阀10在开关过程中的响应速度。
如图6及图7所示，在一个实施例中，每个半壁结构112包括第一弧形壁1121及连接于第一弧形壁1121两端的第二弧形壁1122。而且，第一弧形壁1121朝挤压通道101的外侧凸起，第二弧形壁1122朝挤压通道101的内侧凸起。
也就是说，第一弧形壁1121与第二弧形壁1122的弯曲方向相反，第一弧形壁1121使得挤压通道101对应第一弧形壁1121的区域向外膨胀，具有较大的过流面积；而第二弧形壁1122使得挤压通道101对应第二弧形壁1122的区域向内收缩，过流面积减小，但主体110对应第二弧形壁1122区域的壁厚相应增加。
进一步的，挤压通道101的径向截面内，第一轴a将第一弧形壁1121分为两段，第二弧形壁1122在远离第一弧形壁1121的延伸方向上逐渐朝第二轴b收敛。
第二弧形壁1122在延伸方向上逐渐朝第二轴b收敛，指的是第二弧形壁1122逐渐靠近第二轴b。如此，在第二弧形壁1122的延伸方向上，两个半壁结构112之间的间距也逐渐减小。而且，第一弧形壁1121及第二弧形壁1122使得半壁结构122的内壁更平滑，当挤压通道101闭合时两个半壁结构122能够更好地贴紧。
请再次参阅图6，在第一个实施例中，在挤压通道101的径向截面内，两个半壁结构112同一端的两个第二弧形壁1122延伸至第二轴b并相连。
即，图示位于上端的两个第二弧形壁1122延伸至第二轴b的上端并相连， 而位于下端的两个第二弧形壁1122也延伸至第二轴b的下端并相连。如此，两个半壁结构112更容易贴紧，故在夹管阀10关闭后具有更佳的截流效果。可选的，位于上端的两个第二弧形壁1122在第二轴b的上端相切，而位于下端的两个第二弧形壁1122则在第二轴b的下端相切。
请再次参阅图7，在第二个实施例中，两个半壁结构112同一端的两个第二弧形壁1122通过第三弧形壁114连接，在挤压通道101的径向截面内，第二轴b将第三弧形壁114分为两段，且第三弧形壁114朝所述挤压通道101的外侧凸起。
也就是说，两个半壁结构112的第二弧形壁1122通过第三弧形壁114进行过渡，从而避免两个第二弧形壁1122之间形成角度较小的折角，挤压通道101的内壁更为平滑。如此，能够有效地避免流经挤压通道101的流体在挤压通道101内发生残留，也能够在一定程度上增加挤压通道101的过流面积。
进一步的，具体在本实施例中，第三弧形壁114与相邻的两个第二弧形壁1122光滑连接。如此，能够进一步避免折角的产生，从而使挤压通道101内壁各处均呈光滑的曲面，进一步避免发生残留。
请再次参阅图8，在第三个实施例中，每个半壁结构122包括两个相互连接的平面壁1223，且两个平面壁1223之间的夹角呈钝角。
此时，挤压通道101呈菱形。需要指出的是，挤压通道101不限于呈上述三个实施例中所示出的形状。
基于上述内容，本申请还提供一种电解液注液装置。该电解液注液装置包括夹管阀10、注液杯(图未示)及注液嘴(图未示)，注液杯及注液嘴分别与进液口201及出液口202连通。
注液杯用于存储电解液，注液嘴用于向电池壳体内注入电解液。在进行注液操作时，夹管阀10切换至打开状态，注液杯内的电解液便可经夹管阀10流向注液嘴，并由注液嘴完成注液操作。由于夹管阀10能够保证流量控制的精准度，故上述电解液注液装置的注液精度也较高。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
