Abstract

A touch faucet contains: a body, a temperature control valve, a water control valve, and an actuation member. The body includes an inlet segment, an outlet segment, and a first cavity which has a first hole. The temperature control valve is housed in the first cavity and includes a water inflow portion configured to flow cold water and hot water, a mixing chamber in which the cold water and the hot water are mixed to form a mixing water, and a water outflow portion configured to flow the mix water. The water control valve includes an operation post touched to turn on the water control valve, such that the mixing water flows into the water outflow portion from the mixing chamber, and the actuation member partially exposes outside the body so as to be operated by a user to drive the operation post to move.

First claim

What is claimed is:

1. A touch faucet comprising:
a body including an inlet segment, an outlet segment, and a first cavity defined between the inlet segment and the outlet segment; the first cavity having a first hole;
a temperature control valve housed in the first cavity of the body, and the temperature control valve including a water inflow portion configured to flow cold water and hot water, a mixing chamber in which the cold water and the hot water are mixed together at a predetermined ratio so as to form a mixing water, and a water outflow portion configured to flow the mix water; the water outflow portion being in communication with the outlet segment of the body so that the mixing water flows out of the outlet segment;
a water control valve fixed between the mixing chamber and the water outflow portion of the temperature control valve, and the water control valve including an operation post extending outwardly therefrom and touched to turn on the water control valve, such that the mixing water flows into the water outflow portion from the mixing chamber; and
an actuation member partially exposing outside the body so as to be operated by a user to drive the operation post of the water control valve to move;
wherein the body includes a cylinder and a water supply assembly: the cylinder has the inlet segment and the first cavity; and the water supply assembly has the outlet segment communicating with the water outflow portion of the temperature control valve via the cylinder, such that the mixing water flows into the outlet segment from the water outflow portion;
wherein the water supply assembly has a casing secured on an outer wall of the cylinder, a holder accommodated in the casing adjacent to the outlet segment, a first outlet tube mounted between the holder and the water outflow portion, and an aerator fixed in the holder.

2. The touch faucet as claimed in claim 1 , wherein the actuation member includes a forced portion, and the actuation member includes a driving portion extending from the forced portion and inserted into the water outflow portion of the temperature control valve, wherein the actuation member is pressed to drive the driving portion to actuate, and the operation post of the water control valve is actuated by the driving portion to move.

3. The touch faucet as claimed in claim 2 further comprising a returning device configured to return the actuation member back to an original position, after not pressing the actuation member.

4. The touch faucet as claimed in claim 3 , wherein the returning device is a resilient element which is defined between the actuation member and the water outflow portion, and the resilient element is a disc spring or a compression spring.

5. The touch faucet as claimed in claim 1 , wherein the first cavity of the body has a second hole defined on an inner wall of the first cavity; the water outflow portion of the temperature control valve has a vent formed thereon opposite to the second hole; and the first outlet tube of the water supply assembly communicates with the vent through the second hole.

6. The touch faucet as claimed in claim 1 , wherein the temperature control valve further includes:
a valve seat housed in the first cavity of the body, a first conduit configured to flow the cold water, and a second conduit configured to flow the hot water, hence the first conduit and the second conduit form the water inflow portion;
a valve core connecting with the valve seat and having the mixing chamber defined in the valve core, the valve core also having a flowing channel configured to flow the mixing water and communicating with the mixing chamber, wherein the flowing channel is located at the water outflow portion; and
an adjustment column rotatably fitted with the valve core within a rotatable range and limited between the valve core and the valve seat; between the adjustment column and the valve core being defined a cold-water passage and a hot-water passage; wherein when the adjustment column is rotated, a communicating portion of the cold-water passage and the first conduit and a communicating portion of the hot-water passage and the second conduit are adjustable so as to control a mixing ratio and a mixing temperature of the cold water and the hot water in the mixing chamber.

7. The touch faucet as claimed in claim 6 , wherein between the valve seat and the adjustment column is defined a rotatable limitation structure so as to rotate the adjustment column within the rotatable range.

8. The touch faucet as claimed in claim 7 , wherein the rotatable limitation structure includes a positioning protrusion formed on a top of the valve seat and includes an arcuate groove defined on a bottom of the adjustment column so as to limit a sliding of the positioning protrusion in the arcuate groove.

9. The touch spray head as claimed in claim 6 , wherein the cylinder has a peripheral fence and a support fence connecting with an inner surface of the peripheral fence; and the support fence separates the first cavity from a second cavity in the peripheral fence; the support fence has two third holes, two fourth holes, and a fifth hole; wherein the two third holes respectively accommodate a cold-water supply pipe and a hot-water supply pipe which are connected with the first conduit and the second conduit individually; the valve seat includes two first threaded orifices and a second threaded orifice which are formed on a bottom of the valve seat, and each of two first screw bolts inserts through each of the two fourth holes of the cylinder so as to screw with each of the two first threaded orifices, hence the valve seat is fixed on the cylinder; and a screw rod inserts through the fifth hole of the support fence so as to screw with the second threaded orifice and to lock with a screwing element, such that the valve seat and the cylinder are mounted on a fixing wall in a bathroom or in a kitchen.

10. The touch faucet as claimed in claim 9 , wherein the body further includes a fitting mount arranged on a bottom thereof and abutting with the fixing wall, and the body includes a circular locking shoulder configured to retain with the second cavity below the cylinder.

11. The touch faucet as claimed in claim 6 , wherein the valve seat further has a first connecting slot defined on the top thereof so as to retain with the bottom of the adjustment column; and the valve seat further has a second connecting slot arranged on the bottom thereof so as to retain with a bottom of the valve core; the valve seat further includes a central orifice communicating with the second connecting slot so that a second screw bolt inserts through the central orifice to screw with a third threaded orifice, thus fixing the valve core on the valve seat.

12. The touch faucet as claimed in claim 6 , wherein the valve core has a cylindrical portion and a tubular portion extending outwardly from a bottom of the cylindrical portion; the cylindrical portion forms the water outflow portion, the flowing channel, and the vent; the tubular portion has the mixing chamber defined therein and connects with the valve seat; the adjustment column has a circular rib extending out of the first hole of the body so that the user operates the adjustment column by way of the circular rib, and the adjustment column also has a housing trench defined in a top thereof so as to accommodate the cylindrical portion of the valve core and the actuation member, the housing trench has a first orifice passing through a bottom thereof so as to fit with the tubular portion and has two troughs formed under the first orifice; the cold-water passage and the hot-water passage are defined by the first orifice, the two
