Abstract

A pull-out faucet contains: a hollow body, a control valve assembly, a water supply pipe set, a water hose, and a spray head. The hollow body has a longitudinal chamber, an accommodation groove, and a first orifice. The control valve assembly includes: a right-angle valve block having multiple inlets, an outlet, and multiple apertures. A positioning element is configured to connect the right-angle valve block so as to accommodate a part of the right-angle valve block in the accommodation groove, a mixing valve is configured to communicate with the multiple apertures, a first cap is configured to position the mixing valve in the accommodation groove, and an operation lever is configured to turn on/off and to control the mixing valve.

First claim

What is claimed is:

1. A pull-out faucet comprising:
a hollow body, a control valve assembly mounted on the hollow body, a water supply pipe set communicating with the control valve assembly, a water hose communicating with the water supply pipe set so as to supply water, and a spray head disposed on an outlet segment of the hollow body and communicating with the water hose; the hollow body having a longitudinal chamber, an accommodation groove, and a first orifice defined in the accommodation groove and communicating with the longitudinal chamber; wherein the control valve assembly includes:
a right-angle valve block having multiple inlets, an outlet, and multiple apertures, each of the multiple inlets and the outlet respectively communicates with each of the multiple apertures; the right-angle valve block is moved into the longitudinal chamber from a bottom of the hollow body, and one end of the right-angle valve block corresponds to the first orifice enters into the accommodation grove via the first orifice;
a positioning element configured to connect the right-angle valve block so as to accommodate a part of the right-angle valve block in the accommodation groove;
a mixing valve configured to communicate with the multiple apertures;
a first cap configured to position the mixing valve in the accommodation groove; and
an operation lever configured to turn on/off and to control the mixing valve,
wherein the hollow body includes a casing in which the longitudinal chamber is defined, a seat portion horizontally extends outward from the casing, the accommodation groove is formed in the seat portion; the accommodation groove has a first peripheral rib formed around the first orifice and has at least one first fixing hole adjacent to the first peripheral rib,
wherein the right-angle valve block has a first bottom face configured to flow cold water and hot water, and the right-angle valve block has a peripheral face configured to communicate with the mixing valve; the right-angle valve block further has a locking slot proximate to the peripheral face, and the right-angle valve block has at least one second fixing hole extending to the peripheral face via the locking slot; after the right-angle valve block moves into the accommodation groove from the longitudinal chamber via the first orifice, the at least one second fixing hole corresponds to the at least one first fixing hole so that between each of the at least one first fixing orifice and each of the at least one second fixing orifice is defined a limitation orifice, and
wherein the right-angle valve block further has at least one trench extending from the locking slot and located adjacent to the peripheral face of the right-angle valve block; the positioning element includes a first affix ring and a second affix ring; the first affix ring has a first main part and at least one column extending inward from a first internal fringe of the first main part, wherein an outer diameter of a connection of the at least one column is equal to an outer diameter of the first main part, and an inner diameter of the connection of the at least one column is less than an inner diameter of the first main part; each of the at least one column is retained in each second fixing orifice of the right-angle valve block and the limitation orifice of each first fixing orifice so as to limit the rotation of the right-angle valve block; the first main part of the first affix ring has at least one mounting projection extending from an inner wall of the first main part; the second affix ring has a second main part and at least one crook extending inward from a second internal fringe of the second main part, the second main part has at least one securing notch.

2. The pull-out faucet as claimed in claim 1 , wherein the right-angle valve block has multiple trenches; the first affix ring has multiple columns and multiple mounting projection; and the second affix ring has multiple crooks and multiple securing notches.

3. A pull-out faucet comprising:
a hollow body, a control valve assembly mounted on the hollow body, a water supply pipe set communicating with the control valve assembly, a water hose communicating with the water supply pipe set so as to supply water, and a spray head disposed on an outlet segment of the hollow body and communicating with the water hose; the hollow body having a longitudinal chamber, an accommodation groove, and a first orifice defined in the accommodation groove and communicating with the longitudinal chamber; wherein the control valve assembly includes:
a right-angle valve block having multiple inlets, an outlet, and multiple apertures, each of the multiple inlets and the outlet respectively communicates with each of the multiple apertures; the right-angle valve block is moved into the longitudinal chamber from a bottom of the hollow body, and one end of the right-angle valve block corresponds to the first orifice enters into the accommodation grove via the first orifice;
a positioning element configured to connect the right-angle valve block so as to accommodate a part of the right-angle valve block in the accommodation groove;
a mixing valve configured to communicate with the multiple apertures;
a first cap configured to position the mixing valve in the accommodation groove; and
an operation lever configured to turn on/off and to control the mixing valve,
wherein the hollow body includes a casing in which the longitudinal chamber is defined, a seat portion horizontally extends outward from the casing, the accommodation groove is formed in the seat portion; the accommodation groove has a first peripheral rib formed around the first orifice and has at least one first fixing hole adjacent to the first peripheral rib,
wherein the right-angle valve block has a first bottom face configured to flow cold water and hot water, and the right-angle valve block has a peripheral face configured to communicate with the mixing valve; the right-angle valve block further has a locking slot proximate to the peripheral face, and the right-angle valve block has at least one second fixing hole extending to the peripheral face via the locking slot; after the right-angle valve block moves into the accommodation groove from the longitudinal chamber via the first orifice, the at least one second fixing hole corresponds to the at least one first fixing hole so that between each of the at least one first fixing orifice and each of the at least one second fixing orifice is defined a limitation orifice, and
wherein the positioning element includes a third affix ring and a fourth affix ring which are semicircular, wherein each of the third affix ring and the fourth affix ring has at least one extensions and at least one column.

4. A pull-out faucet comprising:
a hollow body, a control valve assembly mounted on the hollow body, a water supply pipe set communicating with the control valve assembly, a water hose communicating with the water supply pipe set so as to supply water, and a spray head disposed on an outlet segment of the hollow body and communicating with the water hose; the hollow body having a longitudinal chamber, an accommodation groove, and a first orifice defined in the accommodation groove and communicating with the longitudinal chamber; wherein the control valve assembly includes:
a right-angle valve block having multiple inlets, an outlet, and multiple apertures, each of the multiple inlets and the outlet respectively communicates with each of the multiple apertures; the right-angle valve block is moved into the longitudinal chamber from a bottom of the hollow body, and one end of the right-angle valve block corresponds to the first orifice enters into the accommodation grove via the first orifice;
