Abstract

A touch spray head is in connection with a water supply segment of a water supply pipe which is accommodated in a body of a faucet and includes a water channel, the touch spray head and the water supply pipe are pulled out of and retracted back to an outlet of the body, and the touch spray head contains: a casing, a positioning member, a control valve, and an actuation device. The casing includes a hole arranged thereon, the positioning member includes at least one first through orifice, and each of the at least one first through orifice communicates with the water channel and the hole. The control valve includes a movable stem configured to turn on the control valve, and the actuation device partially exposes outside the casing and is operated by a user so as to urge the movable stem of the control valve to move.

First claim

What is claimed is:

1. A touch spray head being in connection with a water supply segment of a water supply pipe which is accommodated in a body of a faucet and includes a water channel; the touch spray head and the water supply pipe being pulled out of and retracted back to an outlet of the body, and the touch spray head comprising:
a casing configured to be held and pulled by a user and including a hole arranged thereon;
a positioning member secured in the casing and including at least one first through orifice formed thereon, and each of the at least one first through orifice communicating with the water channel of the water supply pipe and the hole of the casing;
a control valve housed in the positioning member and including a movable stem configured to turn on the control valve, such that water flows to the at least one first through orifice of the positioning member from the water channel of the water supply pipe via the control valve; and
an actuation device partially exposed outside the casing and being operated by the user so as to urge the movable stem of the control valve to move;
wherein the actuation device includes a press member and a driving member; wherein a first end of the press member is rotatably connected with the positioning member, and a second end of the press member is limited in the casing; wherein an intermediate portion of the driving member is rotatably coupled with the positioning member, a first end of the driving member is abutted by the press member, and a second end of the driving member pushes the push post;
wherein the casing includes a peripheral fence, an opening formed on the peripheral fence so that a part of the press member extends out of the opening to be pressed by the user;
wherein the positioning member further includes a second through orifice corresponding to the opening and configured to accommodate a part of the actuation device; the second through orifice of the positioning member has two opposite first tabs and two opposite second tabs which are in relation to the actuation device; the press member has two first rotary shafts fixed on two sides of one end thereof, respectively, so as to rotatably connect with the two opposite first tabs, individually; the driving member has two second rotary shafts mounted on two sides of the intermediate portion thereof, respectively, so as to rotatably couple with the two opposite second tabs, individually.

2. The touch spray head as claimed in claim 1 , wherein the positioning member includes an accommodation chamber, a housing groove defined on a bottom of the accommodation chamber, and an aperture passing through a bottom of the housing groove; the control valve is housed in the accommodation chamber, and the movable stem inserts into the housing groove.

3. The touch spray head as claimed in claim 2 , wherein the control valve further includes a push post extending out of the housing groove via the aperture, such that the actuation device urges the push post to move the movable stem.

4. The touch spray head as claimed in claim 1 , wherein the positioning member includes an accommodation chamber, a housing groove defined on a bottom of the accommodation chamber, and an aperture passing through a bottom of the housing groove; the control valve is housed in the accommodation chamber, and the movable stem inserts into the housing groove; wherein the control valve further includes a push post extending out of the housing groove via the aperture, such that the actuation device urges the push post to move the movable stem.

5. The touch spray head as claimed in claim 4 , wherein the second through orifice of the positioning member further has a limiting fringe formed therein so as to limit the second end of the driving member between the limiting fringe and the push post.

6. The touch spray head as claimed in claim 1 , wherein the touch spray head further comprises a switching valve assembly disposed on the positioning member and configured to switch water supply mode of the touch spray head, and the touch spray head further comprises a water spray assembly, such that the switching valve assembly is pressed so that the water is guided to the water spray assembly from the at least one first through orifice, thus spraying the water out of the touch spray head.

7. The touch spray head as claimed in claim 6 , wherein the switching valve assembly is pressed so that the water is guided to flow out of a central portion of the water spray assembly or is guided to flow out around a peripheral wall of the water spray assembly.

8. The touch spray head as claimed in claim 7 , wherein the positioning member further includes a first cavity communicating with the at least one first through orifice and accommodating the switching valve assembly; and the positioning member further includes a second cavity configured to house the water spray assembly, wherein the second cavity has a central conduit and a peripheral conduit which are in communication with the first cavity; the water spray assembly includes a central nozzle formed on the central portion thereof so as to flow the water out of the central nozzle; and the water spray assembly also includes multiple peripheral nozzles arranged around the peripheral wall thereof so as to flow the water out of the multiple peripheral nozzles.

9. The touch spray head as claimed in claim 8 , wherein the hole is arranged on one end of the casing away from the water supply pipe, is at the same end as the second cavity.
