其中，所述出液口11位于靠近所述套筒10的另一侧端部处设置，能够有效的延长水流的流动路径，保证加热效果，所述套筒10的一侧端部上设置有一用于对所述套筒10内液体进行杀菌照射的紫外线杀菌单元50。
作为本发明一实施例，所述紫外线杀菌单元50包括：
一基座55，其一侧嵌设于套筒10的一侧端部，另一侧设置有一基板52，所述基板52上朝向所述套筒10内方向的内侧端面上设置有紫外线灯珠57，所述基板52的外侧端面贴合设置有一散热板51，所述散热板51由铝板制成，增强散热效果，所述基座55上开设有一沿套筒10的中心轴向贯通的基孔551；
一密封环53，其设置于所述基孔551内，所述密封环53上开设有一与所述基孔551同轴且贯通的中心孔532，所述密封环53的内壁上开设有一卡槽531，所述卡槽531将所述密封环53分隔成一入射密封环533和一出射密封环534；

尽管本发明的实施方案已公开如上，但其并不仅限于说明书和实施方式中所列运用，它完全可以被适用于各种适合本发明的领域，对于熟悉本领域的人员而言，可容易地实现另外的修改，因此在不背离权利要求及等同范围所限定的一般概念下，本发明并不限于特定的细节和这里示出与描述的图例。
