A kind of transparent Shui nationality germitron around rotation water channel of tool,Include ultraviolet lamp,Shell ontology,Watertight transparent pipe,It is formed with transparent around rotation water channel,The ultraviolet lamp system wears one lateral margin face of shell ontology and prolongs in tool UV discharge tube what shell ontology,The shell ontology lateral margin face can be provided with water inlet and water outlet,The watertight transparent piping is arranged the what shell body interior and can completely entangle UV discharge tube to avoid water flow contact,This is transparent can to enclose Qu Huanshe or plane installs between outside the what shell body interior and the watertight transparent pipe periphery to go for a stroll up and down around rotation water channel,And by this it is transparent around rotation water channel up and down structure characteristic for going for a stroll and generate and increase flow path to reach the design for extending the UV discharge tube and carrying out sterilizing time,The shell ontology inner edge surface of arranging in pairs or groups can be sticked and have the structure of reflecting piece,In order to what combination Hou in use,Water through this it is transparent around rotation water channel water inlet pipe mouth flow into this it is transparent go for a stroll around rotation water channel and revolve Hou,By this it is transparent around rotation water channel effluent pipe mouth outflow,And water flow or air this it is transparent enclose grid and go for a stroll around rotation water channel revolve the effect of Hou and therefore will increase time that UV discharge tube is sterilized and the corresponding and sterilizing function of promotion.一種具透明繞旋水道之水族用紫外線燈裝置，包括有紫外線燈具、殼本體、防水透明管，與透明繞旋水道所組成，該紫外線燈具係穿設殼本體一側緣面延具UV放電管於該殼本體內，該殼本體側緣面可開有進水口與出水口，該防水透明管係套設於該殼本體內部而可將UV放電管完整套住以避免水流接觸，該透明繞旋水道以上下繞彎可圍曲環設或平面置設於該殼本體內部與該防水透明管周緣外之間，並藉由該透明繞旋水道上下繞彎的結構特徵而產生增加水流路徑以達到延長該UV放電管進行殺菌時間的設計，搭配該殼本體內緣面可貼設有反光片的結構，俾於結合
