A water supply apparatus with antibacterial substances is mainly composed of an outer case, a valve and an antibacterial sealing member. The outer case comprises a water inlet joint, an unfiltered water inlet, a filtered water outlet and flow channels connecting the aforementioned inlet, the outlet and joint. The valve can be externally operated at the outside of the outer case through the manual control device. The valve has an antibacterial sealing member for opening/closing the unfiltered water inlet and the filtered water outlet. The surfaces of the antibacterial sealing member or the flow channels are coated with a layer of a mixed solution containing metal ions or particles, capable of being directly used or increasing adhesion through high temperature sintering to compose an antibacterial sealing member so as to form a long life composite antibacterial film. It has a significantly bacteriostatic and sterilization effect and effectively inhibits the growth of bacteria while fluid flows out of the filtered water outlet.一種具有抗菌物質的給水裝置,主要包括一外殼、一閥以及一抗菌密封件所構成;該外殼具有一進水接頭、一未過濾水入口、一過濾水出口以及連接前述的流道;該閥係由人工控制裝置能自外殼外部操作,該閥具有一抗菌密封件開啟或關閉未過濾水入口及過濾水出口;該抗菌密封件或該流道的表面上塗佈一層含金屬離子或粒子的混合溶液,可直接使用或經高溫燒結增加附著性而成一抗菌密封件形成一種長效型的複合抗菌膜,具有顯著的抑菌及殺菌效果,當流體由從過濾水出口流出能有效抑制菌生長的效果。1‧‧‧外殼11‧‧‧進水接頭12‧‧‧未過濾水入口13‧‧‧過濾水出口14‧‧‧流道15‧‧‧水流出口3‧‧‧閥31‧‧‧抗菌密封件4‧‧‧複合抗菌膜
