Abstract

A touch faucet contains: a body, a connector, and a touch valve assembly. The body includes an inlet segment, an outlet segment, a first connecting part, a second connecting part, and an accommodation chamber. The connector is housed in the accommodation chamber and includes an inflow portion, a first coupling portion, a second coupling portion, and an outflow portion. The touch valve assembly is connected with the second connecting part and includes a positioning cylinder which has at least one through orifice, a province valve, and a driving post, such that the water flow enters into the at least one through orifice from the first coupling portion via the positioning cylinder. The touch valve assembly also includes an actuation device, at least one part of which extends out of the body so as to be operated by user and to drive the driving post to move.

First claim

What is claimed is:

1. A touch faucet comprising:
a body including an inlet segment, an outlet segment, a first connecting part, a second connecting part, and an accommodation chamber defined between the first connecting part and the second connecting part;
a connector housed in the accommodation chamber of the body, and the connector including an inflow portion configured to guide water flow; a first coupling portion located opposite to the first connecting part of the body and communicating with the inflow portion; a second coupling portion located opposite to the second connecting part of the body and communicating with the first coupling portion; and an outflow portion communicating with the second coupling portion and the outlet segment of the body so that the water flow enters into the outlet segment;
a touch valve assembly connected with the second connecting part of the body and including a positioning cylinder joined with the second coupling portion, wherein the positioning cylinder has at least one through orifice communicating with the first coupling portion and the outflow portion, a province valve is in connection with the positioning cylinder and has a driving post configured to drive the province valve, such that the water flow enters into the at least one through orifice from the first coupling portion via the positioning cylinder; the touch valve assembly also includes an actuation device, at least one part of which extends out of the body so as to be operated by user and to drive the driving post of the province valve to move.

2. The touch faucet as claimed in claim 1 further comprising a water inflow assembly, and the water inflow assembly including a cold-water inlet pipe and a hot-water inlet pipe; wherein the inflow portion of the connector has a cold-water inlet connected with the cold-water inlet pipe so as to guide cold water into the first coupling portion, and the inflow portion of the connector has a hot-water inlet coupled with the hot-water inlet pipe so as to guide hot water into the first coupling portion.

3. The touch faucet as claimed in claim 2 , wherein the control valve assembly includes a joining part and an operation lever configured to drive the joining part.

4. The touch faucet as claimed in claim 3 , wherein the first coupling portion has a first retaining groove; the joining part has a casing defined between the first connecting part and the first retaining groove; a valve core mounted in the casing; and a rotary shaft extending out of the casing and pulled and rotated by the operation lever; the rotary shaft is pulled to start the cold water flowing into the second coupling portion from the cold-water inlet via the joining part and to start the hot water flowing into the second coupling portion from the hot-water inlet via the joining part; the rotary shaft is rotated to adjust a mixing temperature and a mixing flow of the cold water and the hot water in the second coupling portion.

5. The touch faucet as claimed in claim 2 , wherein the outflow portion of the connector has an outlet, and the body includes a holder and an outlet pipe fitted with the holder on which the inlet segment, the outlet segment, the first connecting part, and the second connecting part form; the outlet pipe forms the outlet segment of the body; and the outlet connects with the outlet pipe.

6. The touch faucet as claimed in claim 5 , wherein the body further includes a fitting mount and a fitting column connecting with the fitting mount; the fitting mount is accommodated in the holder and is fitted with the outlet pipe; and the fitting column is in connection with the outlet, such that the outlet of the connector communicates with the outlet pipe and the fitting mount via the fitting column.

7. The touch faucet as claimed in claim 5 , wherein the inflow portion is located on a bottom of the connector, and the outflow portion is located on a top of the connector.

8. The touch faucet as claimed in claim 2 , wherein the second coupling portion has a second retaining groove; the positioning cylinder includes a housing cavity, a receiving groove defined on a bottom of the housing cavity, and an aperture passing through a bottom of the receiving groove, wherein the at least one through orifice communicates with the second coupling portion via the housing cavity; the province valve is accommodated between the housing cavity and the second retaining groove, and the driving post is housed in the receiving groove; the actuation device includes a drive rod extending into the receiving groove from the aperture so as to drive the driving post of the province valve to move.

9. The touch faucet as claimed in claim 8 , wherein the actuation device further includes a press member exposing outside the second connecting part so as to be pressed by the user, and the second connecting part drives the press member; the drive rod has a limiting segment limited in the receiving groove and configured to drive the driving post to move.

10. The touch faucet as claimed in claim 2 further comprising a spray head pulled out of and retracted back to an outlet segment of a body; a hose having a water inflow end and a water outflow end, wherein the water outflow end is coupled with the spray head so that the hose is pulled outwardly or is retracted inwardly with the spray head.

11. The touch faucet as claimed in claim 10 , wherein the inflow portion and the outflow portion are located on a bottom of the connector.

12. The touch faucet as claimed in claim 1 , wherein an action force of the actuation device to drive the province valve is less than 12 newton (N).

13. The touch faucet as claimed in claim 1 , wherein the control valve assembly and the touch valve assembly are fixed on a central axis.
