Abstract: An ultraviolet irradiation device includes a storage wall defining a space configured to store fluid, and a light source configured to simultaneously emit ultraviolet light and visible light into the space. The storage wall includes a first transmission portion which is formed thinner than other regions of the storage wall and is configured to transmit part of the visible light emitted from the light source to the space.

Abstract: A sterilization device includes: a reservoir, a supply port, an output port and a light source. The reservoir part includes a first half reservoir part having a substantially hemispherical shape and located on an upstream side in a flow direction of the fluid at the supply port, and a second half reservoir part having a substantially hemispherical shape and located on a downstream side in the flow direction. The supply port opens to the first half reservoir part. The output port opens to the second half reservoir part. When the supply port and the output port are projected on a virtual plane orthogonal to an extending direction of an inner surface of a supply channel connected to the reservoir part at the supply port, a center of gravity of the supply port and a center of gravity of the output port are separated from each other.

Abstract: The present invention relates to a sterilization device comprises: a storage part that is for storing a fluid and has a substantially spherical shape; a supply port for supplying the fluid into the storage part; an outlet for extracting the fluid from the storage part; and a light source for radiating ultraviolet light. When the supply port and the outlet are projected on an imaginary plane orthogonal to the extending direction of the inner surface of a supply channel that is connected to the storage part in the supply port, the centroid of the supply port is spaced apart from the centroid of the outlet. The light source is disposed such that the optical axis thereof is positioned at 75° to 105° with respect to a straight line that connects the centroid the storage part and the centroid of the outlet.
