Abstract

A touch spray head is removably connected on an outlet of a faucet body and contains: a casing, a fixing cylinder, a water valve, and a manual operation. The casing includes a surrounding fence, an accommodation space, and a through hole. The fixing cylinder is housed in the accommodation space and includes an inlet segment communicating with the outlet, an outlet segment, at least one first orifice defined between the inlet segment and the outlet segment, and a receiving zone. The water valve is accommodated in the fixing cylinder and includes an operation bar touched to movably turn on the water valve. The manual operation device is housed in the receiving zone and the through hole, and the manual operation device includes a driving portion formed in the through hole so as to be driven by a user to actuate the operation bar to move.

First claim

What is claimed is:

1. A touch spray head being removably connected on an outlet of a faucet body and comprising:
a casing including a surrounding fence, an accommodation space defined inside the surrounding fence, and a through hole formed on the surrounding fence and communicating with the accommodation space;
a fixing cylinder housed in the accommodation space of the casing and including an inlet segment communicating with the outlet of the faucet body, an outlet segment, at least one first orifice defined between the inlet segment and the outlet segment, and a receiving zone;
a water valve accommodated in the fixing cylinder and including an operation bar touched to movably turn on the water valve so that the water flows into the at least one first orifice of the fixing cylinder from the outlet of the faucet body;
a manual operation device housed in the receiving zone of the fixing cylinder and the through hole of the casing, and the manual operation device including a driving portion formed in the through hole so as to be driven by a user to actuate the operation bar of the water valve to move;
a switch valve assembly arranged on the fixing cylinder and configured to switch to water spraying mode; and
a water spray set;
wherein the switch valve assembly is pressed so as to guide the water to the water spray set from the at least one first orifice, thus producing at least two water spraying modes;
wherein the fixing cylinder includes a first trench communicating with the at least one first one orifice so as to fix the switch valve assembly in the first trench; the fixing cylinder further includes a second trench for accommodating the water spray set, wherein the second trench has a central channel and a peripheral channel communicating with the first trench; the water spray set includes a first aperture communicating with the central channel so as to spray the water out of the first aperture in the central spraying mode, and the water spray set includes multiple second apertures communicating with the peripheral channel so as to spray the water from the multiple second apertures in the peripheral spraying mode.

2. The touch spray head as claimed in claim 1 , wherein the fixing cylinder further includes a second orifice formed in the receiving zone and includes a first connection portion; the manual operation device includes a pressing button which has a force portion and a drive stem extending from the force portion; a part of the drive stem is limited in the second orifice of the fixing cylinder; the force portion has an external face and an internal face, wherein the external face has an operating zone configured to form the driving portion, the internal face has a second connection portion rotatably connected with the first connection portion and being opposite to the driving portion in relation to the drive stem, hence when the operating zone is pressed, the drive stem in the second orifice touches the operation bar of the water valve to move by way of the first connection portion and the second connection portion.

3. The touch spray head as claimed in claim 2 , wherein the fixing cylinder further includes a receiving cavity located on the inlet segment, a groove formed in the receiving cavity, and a third orifice passing through the groove, wherein the at least one first orifice communicates with the receiving cavity and the outlet segment; the water valve is accommodated in the receiving cavity, and the operation bar is housed in the groove.

4. The touch spray head as claimed in claim 3 further comprising a push column extending out of the groove from the third orifice and pushing the drive stem of the pressing button to actuate the operation bar.

5. The touch spray head as claimed in claim 4 , wherein the push column includes a fitting portion sliding in the groove, and the push column includes an extension extending out of the third orifice from the fitting portion; the fitting portion is configured to drive the operation bar of the water valve; a distal end of the extension is driven by the drive stem of the pressing button.

6. The touch spray head as claimed in claim 5 further comprising a compression spring accommodated in the groove between the water valve and the fitting portion of the push column so that the push column and the pressing button are pushed by the compressing spring to move back to original positions respectively.

7. The touch spray head as claimed in claim 5 , wherein the extension of the push column has a seal washer fitted thereon and contacting with the groove so as to avoid water leakage out of the third orifice from the groove.

8. The touch spray head as claimed in claim 2 , wherein the first connection portion of the fixing cylinder is at least one rotary shaft; the second connection portion of the pressing button is at least one rotatable tab configured to retain with the at least one rotary shaft.

9. The touch spray head as claimed in claim 8 , wherein the first connection portion is a rotary shaft, and the second connection portion is two rotatable tabs.

10. The touch spray head as claimed in claim 2 , wherein the second orifice of the fixing cylinder has two opposite limiting fringes defined therein so that when the drive stem of the pressing button is pressed and released, the drive stem moves between the two opposite limiting fringes.

11. The touch spray head as claimed in claim 2 , wherein the second connection portion of the pressing button is opposite to the operating zone of the pressing button.

12. The touch spray head as claimed in claim 1 , wherein the water spray set is configured to flow the water in a central spraying mode and a peripheral spraying mode.

13. The touch spray head as claimed in claim 1 , wherein the fixing cylinder further includes a receiving cavity located on the inlet segment, a groove formed in the receiving cavity, and the at least one first orifice communicates with the receiving cavity and the outlet segment; the water valve is accommodated in the receiving cavity, and the operation bar is housed in the groove.

14. The touch spray head as claimed in claim 13 further comprising an inflow connector screwed in the receiving cavity, and the inflow connector having a threaded connecting portion extending out of the casing so as to screw with a screw sleeve on the outlet of the faucet body.

15. The touch spray head as claimed in claim 13 further comprising an inflow connector screwed in the receiving cavity, and the inflow connector has a threaded connecting portion extending out of the casing, wherein the inflow connector has a protruded section formed thereon and has at least one engagement projection arranged around an outer wall of the protruded section and rotatably retained in a screw sleeve formed on the outlet of the faucet body.

16. A touch spray head being removably connected on an outlet of a faucet body and comprising:
a casing including a surrounding fence, an accommodation space defined inside the surrounding fence, and a through hole formed on the surrounding fence and communicating with the accommodation space;
a fixing cylinder housed in the accommodation space of the casing and including an inlet segment communicating with the outlet of the faucet body, an outlet segment, at least one first orifice defined between the inlet segment and the outlet segment, and a receiving zone;
a water valve accommodated in the fixing cylinder and including an operation bar touched to movably turn on the water valve so that the water flows into the at least one first orifice of the fixing cylinder from the outlet of the faucet body
