在本申请中，除非另有明确的规定和限定，第一特征在第二特征之“上”或之“下”可以包括第一和第二特征直接接触，也可以包括第一和第二特征不是直接接触而是通过它们之间的另外的特征接触。而且，第一特征在第二特征“之上”、“上方”和“上面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”包括第一特征在第二特征正下方和斜下方，或仅仅表示第一特征水平高度小于第二特征。
如图1-图5所示，本实施例的防爆阀组件，包括防爆阀主体1和透气膜2。其中，防爆阀主体1内贯通设置有中空腔，防爆阀主体1包括第一端11，第一端11连接于电池包主体，防爆阀主体1包括导向段12，导向段12与中空腔同轴设置，导向段12的内径沿第一方向逐渐增大。示例性的，防爆阀主体1靠近导向段12的侧壁开设有排污口13，示例性的，排污口13连通于中空腔，且位于中空腔的下方腔壁，导向段12使污物堆积于临近排污口13处，污物在重力作用下经排污口13排出。第一方向为防爆阀主体1的轴向，且指向导向管3。透气膜2设置在中空腔内，且沿第一方向，第一端11、透气膜2、导向段12和排污口13依次设置。即从防爆阀主体1远离电池包主体的一端进入中空腔的水和灰尘等污物，经过一段时间后可能沉积在中空腔内，且位于透气膜2远离电池包主体的一侧。通过设置导向段12和排污口13，有助于污物朝向远离透气膜2的方向移动，并从防爆阀主体1远离电池包主体的一端或排污口13排出，从而避免了污物影响透气膜2的受压形变，造成防爆阀组件失效的风险。
为了防止污物从排污口13进入中空腔，示例性的，排污口13的轴向与防爆阀主体1的轴向呈锐角，即排污口13远离中空腔的一端往靠近中空腔一端的面积逐渐增加，即排污口13倾斜开设。
示例性的，该防爆阀组件还包括导向管3，防爆阀主体1还包括第二端14，导向管3卡接于第二端14，中空腔连通于导向管3的内腔。示例性的，防爆阀主体1上设置有第二卡接凸出18，导向管3的侧壁上开设有第二卡接通孔311，第二卡接凸出18与第二卡接通孔311相配合，以实现快速卡接。

示例性的，导向管3包括相连接的水平管31和竖直管32，水平管31卡接于防爆阀主体1，竖直管32的一端开口向下设置。
示例性的，该防爆阀组件还包括第一保护盖4，第一保护盖4盖设在导向管3远离防爆阀主体1的端口处，以防止在车辆行驶过程中，有较大的物体进入中空腔，将透气膜2击穿。

示例性的，该防爆阀组件还包括第二保护盖5，第二保护盖5盖设在透气膜2远离导向段12的一侧。由于透气膜2与防爆阀针7之间的距离非常小，设置第二保护盖5能够防止装配过程中人为触碰透气膜2，以使透气膜2接触防爆阀针7，造成透气膜2击穿。
示例性的，第二保护盖5卡接于防爆阀主体1，示例性的第二保护盖5上设置有第一卡接凸出51，防爆阀主体1的侧壁上开设有第一卡接通孔17，第一卡接凸出51与第一卡接通孔17相配合，以实现快速卡接。
为了固定透气膜2在中空腔内的位置，示例性的，防爆阀主体1的内壁设置有台阶部15，台阶部15包括垂直于防爆阀主体1轴向的支撑面151，透气膜2焊接于支撑面151。
