A pull-out faucet main body including a valve core seat assembly and a pull-out faucet are provided. The faucet main body is composed of a main pipe and a side wall branch pipe. The valve core seat assembly includes a valve core seat and a main body fixing seat. The main body fixing seat has a body that matches an included angle between the main pipe and the side wall branch pipe. A lug is additionally provided horizontally outward on an outer side of the body, and at least one water inlet channel and a water outlet channel which are independent from each other are provided in an inner cavity of the body, and the main body fixing seat is locked and fixed inside the main pipe by a nut, and the valve core seat is exactly engaged into the side wall branch pipe.

A fluid delivery device comprises a faucet. The faucet includes a hub, a sprayhead, and a hose coupling the hub to the sprayhead. Each end of the hose has a pivot coupling. One of the pivot couplings is configured to permit rotation of the hose relative to the hub. Another of the pivot couplings is configured to permit rotation of the sprayhead relative to the hose.

Disclosed herein is a two-layer vanity unit. The two-layer vanity unit includes: a cabinet; an upper vanity unit disposed on a top of the cabinet and exposed to the outside; a lower vanity unit disposed inside the cabinet so that it is selectively put into the cabinet when not in use and withdrawn from the cabinet when in use; drain pipes connected to the upper and lower vanity units; and cold and hot water pipes connected to the upper vanity unit. Control is performed to adjust one or more of water supply and water cutoff for the upper or lower vanity unit and an amount and temperature of the available water according to an operation mode of the lever of the faucet provided on the upper or lower vanity unit, thereby controlling a type of supply of available water.

A faucet assembly including a spout with dual flow outlets resulting in two separate streams of water from a discharge outlet that combine into a single stream a distance below the flow outlets. In an illustrative embodiment, the faucet spout is formed is formed through additive manufacturing.

A drain valve structure contains: a body and a stop assembly. The body includes: an accommodation holder, a fixing holder, and a connection seat. The accommodation holder has a threaded groove, a through hole, and a threaded section. The fixing holder includes a first coupling segment, a connecting section, a second coupling segment, and a stepped orifice. The connection seat is connected with the second coupling segment and has an extension, a fitting segment, and an opening. The stop assembly includes a first ring, a second ring, and a third ring which are made of non-metal, the first ring is fixed on an inner wall of the threaded groove of the threaded section, the second ring is fitted with an inner wall of the stepped orifice of the fixing holder, and the third ring is fitted with an inner wall of the opening of the connection seat.

A faucet includes a faucet body and a spout attached to the faucet body and extending from the faucet body along an axis. The spout has an interior defining a fluid path. A cartridge seat is positioned within the faucet body and contacts a valve cartridge positioned offset from the axis. The valve cartridge is fluidically connected to the cartridge seat. A flexible tube fluidically connects between a fluid outlet of the cartridge seat and the spout, and is positioned entirely within a cavity formed by the faucet body and the spout.

A faucet assembly includes a housing which includes a first faceplate defining a first and second opening which extend through the first faceplate and spaced apart and a seal member on the first faceplate which surrounds the first and second openings. A cartridge assembly positioned within an opening in the housing which includes a second faceplate, which abuts the seal member and forms a seal between the second faceplate and the seal member. Second faceplate defines third opening which extends through the second faceplate. With rotation of the second faceplate, third opening changes position relative to first faceplate to include the third opening positioned in one of: alignment with a portion of first opening and a portion of second opening, alignment with the first opening or alignment with the second opening.

A crank connection structure includes a crank and a connection pipe. The crank and the connection pipe are connected in a plug-in manner and are rotatable relative to each other. A sealing ring is provided between the crank and the connection pipe. A faucet includes a body and the crank connection structure. The connection pipe is connected to the body. For the crank connection structure and the faucet using the structure, during the installation, only the angle relationship between the crank and the connection pipe needs to be adjusted, and the sealing ring is used for sealing the crank and the connection pipe without requiring raw material belt. The angles between the faucet body and the two cranks can be simultaneously adjusted to be at same level by rotating the faucet body, which abandons the traditional way of separately adjusting the cranks for leveling, achieving faster installation and adjustment.

Disclosed is a fitting structure of a water outlet device. The fitting structure comprises a fixed block, hoses, and joints. A peripheral of the fixed block comprises first position holes configured to be fixedly disposed with the hoses. The joints are fixedly connected to first ends of the hoses disposed above an upper surface of the fixed block, and each of the joints comprises a first water outlet passage and a second water outlet passage in communication with the first water outlet passage. An axis of each of the first water outlet passages and an axis of a corresponding one of the hoses is coaxial. The second water outlet passage is parallel to and is staggered with the first water outlet passage by a preset distance. The joints are staggered with the hoses by the preset distance in a radial direction and an outward direction of the fixed block.

System for washing the hair, including a first reservoir for receiving a first liquid (L1) constituted by or comprising water, a second reservoir for receiving a second liquid (L2) comprising a treatment product diluted in water in an amount of less than or equal to 2.5% by weight relative to the total weight of the second liquid (L2), a shower head with a supply rate of between 0.3 and 5 L/min, configured to deliver a jet of droplets onto the hair, and a means for supplying the shower head with liquid, taken exclusively from one or other of the reservoirs, with an overpressure.
