A disinfection device for a trapped-liquid comprising of a drain trap for a liquid flow having an inner surface to trap a volume of the trapped-liquid and a helical coil capable of generating metal ions to eliminate biological cells attached to said drain trap. An electric valve is connected to a tap water and the helical coil and a power supply provides a current and a voltage to the helical coil for a period of ionization and a sensor system installed in the drain trap to sense flow of a liquid through the drain trap. A timer system to determine the length of a stagnant-time that the trapped-liquid is stagnant in the drain trap; and to determine the length of an ionization-time for the period of ionization.

The present disclosure relates to the field of fluid switches, and more particularly to an extractable faucet, comprising a faucet housing configured as a tubular member with a cavity; a faucet body including an extractable head and an extractable conduit, an water inlet end of the extractable head is connected to the extractable conduit; a first support received in the cavity and located in a water outlet end of the faucet housing, the extractable head is freely received in the first support and a purified water pipe is embedded detachably into the first support; a mounting seat configured to function as a water distributor and is detachably engaged with the faucet housing; a valve cartridge received in the mounting seat and is used for controlling the shut off of the extractable conduit and the purified water pipe, and separating the flow path of the tap-water and that of the purified water. The extractable faucet makes the purified water line incorporate into the extractable faucet and is controlled by one valve cartridge for the switching on and the switching off for the purified water and tap-water, satisfying the use convenience requirement of user for direct drinking water, while reducing the occupied area in the kitchen and improving user experience.

A waterway transferring device comprises a transferring body, a water outlet joint, and an anti-releasing mechanism. The transferring body comprises a first water inlet passage, a second water inlet passage, and a water outlet passage. The water outlet joint comprises an outer joint and an inner joint extending in the outer joint and connected to the first water inlet passage. The anti-releasing mechanism comprises a first anti-releasing member and a second anti-releasing member. When the outer joint is rotated to be connected to the water outlet passage, the first anti-releasing member and the second anti-releasing member are rotated relative to each other to be connected together, and when the outer joint is rotated reversely, the first anti-releasing member and the second anti-releasing member abut each other in an opposite direction to inhibit a rotation of the outer joint.

The present inventive concept relates to a water recycling device comprising: an outlet configured to output treated water; a drain for collecting used water output from said outlet; a return/evacuation path in liquid communication with said drain, wherein said return/evacuation path comprises an inlet for receiving water collected by said drain; a return path in liquid communication with said return/evacuation path; a treatment path in liquid communication with said return path and said outlet; an external water path in liquid communication with said treatment path, said external water path being connected to an external water outlet; a valve arrangement configured to accept as inputs used water from said return path and/or external water from said external water path, said valve arrangement being placed between said return path and said treatment path, said valve arrangement being configured to direct said inputs to said treatment path, said valve arrangement being configured to mix said external water with said used water from said return path; a circulation pump for providing a flow in said water recycling device; and a water treatment arrangement placed downstream to said valve arrangement.

Provided by the present invention is a faucet water purifier for filtering a raw water, which comprises a control valve and a filtering device, wherein the filtering device defines a first communicating opening and a second communicating opening, the control valve comprises a valve body and a valve core, wherein the valve body defines a valve cavity, a first opening, a second opening, a third opening, a raw water inlet and a draining opening, wherein the valve core is disposed inside the valve cavity, wherein the first opening is communicated with the first communicating opening of the filtering device, the second opening is communicated with the second communicating opening of the filtering device, the third opening is communicated with a water outlet of the filtering device, and the raw water inlet of the valve body is adapted to be communicated with a raw water source.

In a filter insert for use in a water outlet fitting with integrated drinking water filter, which has a structure closed on all sides and with an inner hollow space and in which at least a part of its outer surface is designed as a filter-active surface through which water to be filtered passes from the outside inward, a mouthpiece pointing outward in the shape of a collar and forming a mouth orifice is arranged which can be received by an opening in a fitting-side filter housing and from which filtered water can flow freely out of the inner hollow space without contact with the filter housing.

A multifunctional water outlet fitting for selectively dispensing service water and filtered drinking water has a fitting member having at least one water supply, a first outlet for service water which branches off from the fitting member, a second outlet for filtered drinking water which branches off from the fitting member and, for a drinking water filter, a filter receiving space through which water can flow connected to the second outlet so as to carry water. The filter receiving space is formed by a filter housing which is arranged at the end of the second outlet facing away from the fitting member, and the filter housing has a downwardly facing base in which there is formed a mouth opening, from which filtered drinking water can be removed. The filtered drinking water is consequently removed directly from the filter housing so that any formation of germs in a connected waterway is prevented.
