In accordance with aspects and embodiments, a multifunctional smart faucet system is provided comprising a faucet that, in addition to having traditionally plumbed hot and cold water lines, includes a plurality of reservoirs, each of the plurality of reservoirs having a reservoir channel extending from the reservoir through the body of the faucet. The faucet systems disclosed includes a manual push button able to dispense fluids in the reservoirs, as well automated systems for dispensing fluids on intervals and according to pre-determined programming. In some embodiments, the disclosed smart faucet systems are controllable by smart devices with the aid of a dedicated application.

The present disclosure provides a luminous water outlet device, which includes a hydroelectric power generation module, a waterway separation body, a waterway switching module, a water outlet panel, and a light board. The hydroelectric power generation module is arranged at a water inlet, the waterway separation body has two waterways, the waterway switching module is used to switch a flow of water in the two waterways, and the water outlet panel is correspondingly arranged below the two waterways, the light board is electrically connected with the hydroelectric power generation module. Compared with the prior art, the hydroelectric power generation module is arranged in the water inlet to ensure that the light board works no matter which waterway is opened and allows water to flow through. Further, the present disclosure has simpler installation, smaller volume, and simpler waterway structure.

Provided is a mixer faucet configured such that a lubricant can be effectively supplied. The mixer faucet includes a fixed valve body and a movable valve body. The fixed valve body includes a hot water supply hole, a cold water supply hole, a drain hole, a first sliding surface, and a lubricant retention portion. At least a part of the lubricant retention portion is provided in a circumferentially extended region of the hot water supply hole and a circumferentially extended region of the cold water supply hole. In the circumferentially extended region, only the first sliding surface is present between the hot water supply hole and the lubricant retention portion. In the circumferentially extended region, only the first sliding surface is present between the cold water supply hole and the lubricant retention portion.

Provided is a liquid dispensing device. The liquid dispensing device includes a cylinder body coupled to a sink and at least one nozzle coupled to the cylinder body. The at least one nozzle may include a first liquid discharge nozzle coupled to an upper region of the cylinder body to extend horizontally, the first liquid discharge nozzle being configured to supply a drinkable liquid, such as a purified liquid, a heated liquid, or a cooled liquid. The at least one nozzle may a second liquid discharge nozzle coupled to the cylinder body to extend horizontally, the second liquid discharge nozzle being positioned to be spaced apart from the first liquid discharge nozzle to supply a non-drinkable liquid, such as a sterilizing liquid containing hypochlorous acid or other additive.

A faucet hose adapter includes an elongated tube having a first end opposite a second end defining a channel therebetween. The first end is dimensioned to secure over a faucet such that fluid dispensed from the faucet exits through the second end. An aperture is disposed through the elongated tube adjacent to the first end, wherein the aperture can receive a faucet valve handle therethrough.

A domestic water tap (1000) is disclosed. The present application relates to a tap and an inner body for routing liquid within a tap, for example, a domestic water tap or faucet. The domestic water tap (1000) comprises an outer body (1010, 1012) and an inner body (100). The inner body (100) is housed within the outer body (1010, 1012). The outer body (1010, 1012) comprises at least one flow channel (1020, 1022) in which water can flow through the tap (1000) without contacting the outer body (1010, 1012). The inner body (100) is made from plastics and comprises at least one non-threaded bore for securely receiving a connector for delivering water from a source into the inner body (100).

A set of universal switching modules is provided for mechanical touch faucets. The switching modules afford the same operational benefits and features as an electronic faucet without the necessity of resort to an electrical power supply, eliminating the need for electronic control circuitry, and simplifying installation while increasing long term operational reliability. The switching modules are activated by a linear depressing or a rocking motion that contrasts with rotary motions associated with rotating a valve stem. The switching module designs are agnostic to the faucet design meaning that the switching modules are universal in that the modules fit any faucet design. The switching modules work with a variety of activation methods used in faucet design illustratively including rocker switch concepts, push concepts, and a horizontal/perpendicular push concepts. Faucet manufacturers purchase a module based on the type of activation that they prefer for seamless integration in their faucet design.

Novel plumbing products, including faucets, are fabricated, e.g., using metallic 3-dimensional or other 3-D printing techniques, to have complex geometries, such as multiple channels that may diverge and re-converge near the spout. The geometries of the various channels can resemble interwoven net-like patterns that define various shapes between the channels. The plumbing fixtures may be formed from one or more of stainless steels, INCONEL, brass, bronze, polycarbonate, PVC, acrylics, rigid polyolefins, PET, carbon fiber, AES, or other plumbing fitting suitable corrosion resistant materials. In some embodiments, the handles of an exemplary faucet can include the same or a similar multiple channel configuration as the spout, providing an advantageously, aesthetically pleasing faucet system. In exemplary embodiments, faucet spouts and their handles are formed so as to couple to standard faucet underbodies, standard valve platforms, or standard threaded hose/waterway connections.
