| 发明名称 | Sterilization device | ||
| 摘要 | A sterilization device includes a housing having a flow passage R of a fluid that is to be sterilized; and an LED element being disposed in the housing to irradiate ultraviolet light into the flow passage R, wherein an inner wall surface of the flow passage has a pair of reflection surfaces (a first reflection surface and a second reflection surface) which directs the ultraviolet light irradiated from the LED element from one side of the flow passage R to another side thereof while reflecting the ultraviolet light a plurality of times; and a return surface that includes a surface that is perpendicular to an optical axis of the light which has been reflected a plurality of times from one side to the other side, and returns the light toward its original direction is formed on a side of the first reflection surface. | ||

| 主权项 | 1. A sterilization device, comprising: a housing having a flow passage of a fluid that is to be sterilized; and a light source being disposed in the housing to irradiate ultraviolet light into the flow passage, wherein an inner wall surface of the flow passage has a pair of reflection surfaces which direct the ultraviolet light irradiated from the light source from one side of the flow passage to another side thereof while reflecting the ultraviolet light a plurality of times; and a return surface disposed within the flow passage and that is composed of a surface that is perpendicular to an optical axis of the light which has been reflected a plurality of times from the one side to the other side, and returns the light toward its original direction is formed on a side of one of the pair of reflection surfaces. | ||
