A fluid purification device includes a screen plate, a first filtration layer, a second filtration layer, a third filtration layer, a main body, and a dispensing plate. The screen plate has a plurality of inflow holes for filtering particles in fluid passing therethrough. Around a periphery of the screen plate, several convex sections are arranged and spaced apart from one another. The main body is hollow and has an open top and an open bottom opposite to the open top. Around an inner wall of the open top, several concave sections are arranged and spaced apart from one another. The concave section is shaped in conformity with the convex section, so that the screen plate can be secured to the open top of the main body.

The present inventive concept relates to a method for recycling water in a water recycling device, the method comprising: receiving used water via a drain; determining a water quality measure of the used water; if the water; quality measure of the water is above a first quality threshold, feeding the used water to a valve arrangement; in the valve arrangement, forming water to be treated by providing external water, the used water or a combination of the external water and the used water; generating treated water by treating the water to be treated using a water treatment arrangement; and feeding the treated water to an outlet. The present inventive concept also relates to a water recycling device.

The present invention provides a valve element cover plate, comprising a cover plate body. The cover plate body is provided with a water mixing valve mounting position and at least one switching valve mounting position. A cold water inlet, a hot water inlet and water outlets connected to water mixing valve mounting position are arranged on the back of the cover plate body; a water diverting channel is arranged in the cover plate body. A mixed water channel is arranged in the water mixing valve mounting position; fixing parts are arranged on the side of the cover plate body. The present invention has good sealing effect, and can maintain good sealing performance even when the cover plate body is deformed. It also has good filtering effect, and can effectively reduce the wear of downstream switching valve elements, and avoid blockage at the downstream outlets.

A light sanitization system and method is disclosed that provides neutralization of pathogens and chemicals by embedding light waveforms within a stream of fluid.

Provided is a mixer faucet that can suppress the occurrence of water leakage. A mixer faucet includes: a fixed valve body including a hot water supply hole, a cold water supply hole, and a drain hole; a movable valve body that includes a flow path forming recess and is configured to slide on the fixed valve body; and a handle configured to control the movable valve body. The fixed valve body includes a collection groove that is not connected to either the hot water supply hole or the cold water supply hole and is connected only to the drain hole. The collection groove can capture water leaking from the hot water supply hole, the cold water supply hole, or the drain hole. The captured water can flow into the drain hole through the collection groove.

This disclosure relates to a sanitary fitting for dispensing prepared liquids, for example, for beverages. A disclosed system includes a first control element for setting a quantity of the prepared liquid to be dispensed and an actuating element for providing the quantity of prepared liquid set by means of the first control element, wherein at least one second control element is configured to select a type of preparation, for example, from at least two different types of preparation, of non-prepared liquid, wherein the first and the at least one second control element are actuatable independently of one another.

Water disinfecting modules, water supply systems, methods of assembling a water supply system as well as method of disinfecting water are provided. The water disinfecting module includes a frame, hot and cold water flow switches and hot and cold UV treatment modules is provided. The frame supports a hot and cold water inlets and hot and cold water outlets. Hot and cold water flow switches are fluidly interposed between the respective inlets and outlets for sensing water flow. Hot and cold water UV treatment modules are fluidly interposed between corresponding inlets and outlets and are coupled to flow switches for activation upon sensing of water flow. All of the components are supported by the frame to form a complete unit. The systems and methods incorporate the use of such a water disinfecting module.

A multi-mode showerhead having a housing with a front and a rear and an offset integrated water filter system incorporated into the showerhead. The multi-mode offset filtered showerhead has multiple nozzle assemblies, one of which is movable or rotatable and another of which is removable and may contain a unit to hold a water filter cartridge for insertion and removable from the integrated water filter system incorporated into the showerhead. A selector switch and other water flow control devises are used to selectively control the flow of water through the showerhead to the nozzle assemblies. The showerhead is mounted on a shower arm by means of a single water inlet on the rear of the housing and is fluidly connected to a hollow filter chamber in the integrated water filter system.

A filter cartridge for a showerhead includes a frame having an upstream plate and a downstream plate, both having a respective plurality of openings formed therein. The frame defines at least one upstream void outside of the upstream plate, and at least one downstream void outside of the downstream plate. A filter element is coupled to the frame and has a conical configuration including upstream and downstream faces, and a sidewall extending between the upstream face and the downstream face, with the upstream face being smaller than the downstream face. The filter element is positioned relative to the frame with the upstream face in direct fluid communication with the at least one upstream void and the plurality of openings formed in the upstream plate, and the downstream face in direct fluid communication with at least one downstream void and the plurality of openings formed in the downstream plate.

Provided is a functional unit for a bathroom that includes a functional component for a bathroom, separated from a water faucet device and fixed to a bathroom wall part; and a reforming unit that is formed integrally with the functional component for a bathroom and that includes a cartridge capable of reforming raw water flowing through a water supply passage from the water faucet device to a water discharge device. The reforming unit includes a casing that houses the cartridge, and the casing is detachably connected to the functional component.
