The present invention discloses an ultraviolet light-emitting faucet comprising an inlet assembly, an outlet assembly, an operation assembly configured between the inlet assembly and the outlet assembly, and a waterproof light emitting module disposed in the operation assembly. The operation assembly has a conduit and an operation room that communicates, the waterproof light emitting module is disposed in the conduit and capable of emitting an ultraviolet light into the operation room in order to sterilize the water flowing through the operation room.

A fluid treatment device including: a pipe having an inlet through which fluid is introduced into the pipe from a fluid treatment space, an outlet through which sterilized fluid is discharged to the fluid treatment space, and a flow channel connecting the inlet to the outlet, the pipe providing a sterilization area in the flow channel; a solvent filling at least a portion of the sterilization area; and at least one light source module disposed in the sterilization area, and including a light source to emit sterilizing light and a substrate on which the light source is mounted, in which the fluid introduced through the inlet passes through the solvent towards the outlet, the solvent traps contaminants contained in the fluid when the fluid passes through the solvent, and the light source module sterilizes the solvent with the contaminants trapped therein.

A fluid treatment apparatus including: a pipe having an inlet and an outlet through which a fluid is configured to pass, and a flow channel connecting the inlet to the outlet to define a sterilization area; a fan to control a flow of the fluid; and at least one light source module including a light source to emit sterilizing light towards the sterilization area of the pipe and a substrate, in which the inlet and the outlet of the pipe are disposed adjacent to bottom and top surfaces of an external space of the pipe, respectively, the pipe includes a bent portion such that a flow direction of the fluid passing through the inlet and the outlet of the pipe is different from a flow direction of the fluid passing through sterilization area, and a length of the sterilization area is greater than a diameter of the sterilization area.

This disclosure relates to aggregating, neutralizing, and filtering ultra-fine particles in fluids such as air and water. Fluid may be drawn from an ambient environment into a neutralization chamber. Within the neutralization chamber, particles in the fluid may be agglomerated. An acoustic field may be applied to the fluid to agglomerate the particles. The agglomerated particles may be exposed to light. The light may denature or deactivate the agglomerated particles. The agglomerated and inert particles maybe passed through a filter. After agglomeration and neutralization, the fluid may be released back into the ambient environment.

A portable water bottle includes a water bottle body having water stored therein; and a sterilizing module for irradiating the inside of the water bottle body with sterilizing ultraviolet rays. The sterilizing module further includes a housing having an ultraviolet outlet through which the sterilizing ultraviolet rays pass; a light source module for emitting the sterilizing ultraviolet rays; and a power storage member for supplying power to the light source module.

A water tank configured to store water from a water supply includes an inlet configured to receive water from the water supply, and an outlet configured to dispense water. The water tank includes a reflective coating positioned on an inner surface of the tank, and an end wall including a light emitting diode oriented toward the outlet. The light emitting diode and the reflective coating are operable to disinfect water from the water supply

A sterilizer for an aquarium includes a pump for sucking water in an aquarium and a filtering member for filtering the water. The pump includes an inlet from which the water in the aquarium is sucked. The filtering member is connected to the underside of the pump and includes an outlet through which the filtered water flows back into the aquarium. Multiple reflectors are connected to the periphery of the filtering member, and a coat is mounted to outside of the filtering member and covers the reflectors. Multiple ultraviolet sterilizer bulbs are located in the filtering member so as to treat the water sucked from the pump. A cotton sleeve is mounted to the pump and located around the inlet to remove debris and grease.

Metal working fluid decontamination apparatus (10) includes: an intake arrangement (40) for metal working fluid (42); a pump (16) for providing, in use, flow pressure to the metal working fluid (42); a decontaminator (50) for reducing contamination in the metal working fluid (42); and an outlet arrangement (34) for the metal working fluid. The metal working fluid (42) is a fully synthetic metal working fluid, which comprises water and a water soluble synthetic concentrate which does not comprise oil.

A method and apparatus for treating a liquid using ultraviolet radiation. A thin flow of liquid in a supercritical flow is irradiated by at least one radiation source external to the thin flow. The flow may desirably have a Froude number greater than 3 and a velocity greater than 0.8 m/s. The apparatus for treating a liquid including may have a reservoir supplying liquid though a slot into an open channel to generate a thin flow of liquid having a supercritical flow along the channel with at least one radiation source external to the thin flow to irradiate the thin flow.
