同时，现有水龙头盖在首次使用时，出液管不便于将用于封堵作用的密封片撕裂，造成使用不安全卫生和出液不顺畅。
为此，本发明即针对现有技术的不足而研究提出。

与现有技术相比较，本发明一种水龙头盖，具有以下优点：
1、本发明的阀门杆与套管之间通过导向凸起和螺旋导向槽配合连接，故阀门杆转动时，可相对套管轴向运动，相应顶压撕裂第一密封件和第二密封件，使出液口敞开，或使阀门杆远离出液端孔而轴向移动以将出液口与出液端孔导通，或使阀门杆抵近出液端孔而轴向移动以将出液口密封堵住，具有操纵便捷及结构简单的特点；同时，通过将第一密封件和第二密封件设在套管上，即设在阀门杆沿套管轴向运动路径上，则便于阀门杆作用第一密封件和第二密封件撕裂，及在连接座上部与套管之间或连接座上部设有进气口，为此具有使用安全卫生和出液顺畅的特点。

【具体实施方式】
下面结合附图1-12对本发明的实施方式作详细说明。
如图1-12所示，本发明一种水龙头盖，包括连接座1和阀门杆2，所述连接座1用于与容器口部或管端口部连接，所述连接座1上部设有套管3，所述套管3两端开口且分别为连接端孔31和出液端孔32，所述连接座1上部与套管3之间设有出液口11，所述套管3上且位于连接端孔31与出液口11之间可撕裂设有第一密封件33，所述套管3上且位于出液端孔32与出液口11之间可撕裂设有第二密封件34，所述阀门杆2可从连接端孔31插入套管3内，所述阀门杆2与套管3之间设有当阀门杆2相对套管3转动时可相应沿套管3轴向运动的导向机构。所述阀门杆首次插入套管前，阀门杆可拆卸连接于连接座上，且当阀门 杆首次插入套管沿一方向转动时，阀门杆同时向出液端孔轴向移动并顶压撕裂第一密封件和第二密封件而致使出液口敞开，当阀门杆沿另一方向转动时阀门杆同时沿连接端孔轴向移动并使得出液口与出液端孔导通。如图1-2所示，在使用前，阀门杆插放于连接座上，使用者首次使用时，则将可拆卸连接在连接座上的阀门杆取下，然后通过导向机构将阀门杆旋入套管内，旋入后的阀门杆外侧壁与套管的内侧壁则密封接触，故能将敞开的出液口密封堵住。因此采用本发明结构，具有结构简单、制造成本低、操纵使用便捷、使用安全卫生、出液顺畅，以及使用后仍能密封保存的特点。
根据设计需求，所述导向机构包括设在相应阀门杆2和套管3上互相配合的导向凸起35和螺旋导向槽21。
如图1-12所示，所述导向凸起35设在套管3内壁上，相应地所述螺旋导向槽21设在阀门杆2上。转动阀门杆时，螺旋导向槽21则沿着导向凸起35滑动，故阀门杆可相应地沿套管的轴向移动。
如图1-12所示，根据设计需求，所述套管3沿横向设在连接座1上部。
如图1-6所示，为了便于放置阀门杆，所述连接座1上设有用于容纳放置阀门杆1的存放空间4。
进一步地，所述存放空间4为靠近于连接端孔31且沿竖向设在连接座1上的盲孔。如图1和图2所示，在使用前的初始状态，阀门杆则插放于存放空间内，有效提高组装的便利性。
如图1、3、5、7、9、11所示，为了使用方便，所述阀门杆2外端上设有扳手22。
如图1-6所示，为了出液顺畅，所述连接座1上部与套管3之间设有进气孔12，所述进气孔12上密封连接有可撕裂的进气密封件121。
如图7-12所示，为了出液顺畅，所述连接座1上部位于连接端孔31一侧设有进气孔12，所述进气孔12上密封连接有可撕裂的进气密封件121，所述阀门杆2上设有用于撕裂进气密封件121的破坏进气结构。
进一步地，所述破坏进气结构为设在阀门杆2外端上的进气开启件23。
如图7-12所示，为了使阀门杆相对套管稳定连接且防止阀门杆在初次使用前掉落、丢失，所述第一密封件33朝向连接端孔31一侧上设有用于与阀门杆 2插接的插接管套图中未标示出来，具有干净卫生的特点。
第一具体实施例的工作原理：如图1-6所示，所述阀门杆首次插入套管前，阀门杆可拆卸连接于连接座上，为了便于驱动阀门杆转动，在阀门杆外端上设有扳手，且当阀门杆首次插入套管内时，作用扳手，阀门杆可转动并向出液端孔轴向移动使得进气密封件、第一密封件和第二密封件被撕裂，相应地出液口和进气口则敞开，当阀门杆沿另一方向转动时，该阀门杆同时沿连接端孔轴向移动并使得出液口与出液端孔导通，进气口同时与外界及容器内腔连通。故进行倒液时，外界的空气则通过进气口进入容器内腔，出液口及出液端孔均可以顺畅地流出。
待倒取结束后，则可旋转阀门杆使其向出液端孔方向移动而将进气口、出液口和出液端孔封堵住，为此具有重复密封使用的特点，同时确保开启使用后仍能密封存放。
第二具体实施例与第一具体实施例的不同之处在于：
第二具体实施例工作原理：如图7-12所示，初始状态时，阀门杆连接于套管连接端孔一侧上，为了便于驱动阀门杆转动，在阀门杆外端上设有扳手，首次使用时，使用者作用扳手，阀门杆可转动并向出液端孔轴向移动使得第一密封件和第二密封件被撕裂，进气开启件使得进气密封件被撕裂，相应地出液口和进气口则敞开，且进气口将外部与容器内腔导通，当阀门杆沿另一方向转动时，阀门杆同时沿连接端孔轴向移动并使得出液口与出液端孔导通。故进行倒液时，外界的空气则通过进气口进入容器内腔，出液口及出液端孔均可以顺畅地流出。
