Description
FAUCET
FIELD OF THE INVENTION
The present invention relates to faucets, and more particularly to a pull-out faucet and a pull-down faucet.
BACKGROUND OF THE INVENTION
A conventional pull-out or pull-down faucet contains a hollow body, a control assembly arranged on a basin (in a kitchen), and an inlet pipe set including a cold-water inlet pipe and a hot-water inlet pipe and connected with the control assembly so as to supply mixing water of cold water and hot water to a mixing valve set of the control assembly.
A mixing ration of the mixing water is controlled by using a control element of the control assembly. A mixing-water outlet pipe is coupled with the control assembly so as to guide the mixing water. A pull hose is connected with the mixing-water outlet pipe so as to supply the mixing water to a spray head from the hollow body, wherein the spray head is fixed on an outflow portion of the hollow body so as to pull the spray head to any position of a water tank. A
counterweight assembly is secured on the pull hose under the basin, when the spray head is retracted or pulled, it moves back to an original position by using the counterweight assembly.
The basin has a housing aperture through which a threaded pipe is inserted so as to screw with a bottom of the hollow body, and a screw element is screwed with the threaded pipe and is abuts against a bottom fence of the basin, thus locking the hollow body on the basin.
When the pull hose contacts with the inlet pipe set and the mixing-water outlet pipe and the spray head is pulled, the pull hose is pulled forcefully. When the spray head is removed, it cannot move back to the original position quickly. To overcome such a problem, a size or a weight of the counterweight assembly is increased.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
SUMMARY OF THE INVENTION
One aspect of the present invention is to provide a pull-out faucet and a pull-down faucet which contain a spray head pulled and retracted smoothly.
Further aspect of the present invention is to provide a pull-out faucet and a pull-down faucet which contain a hollow body fixed securely by using an isolation pipe and a connection set.
Another aspect of the present invention is to provide a pull-out faucet and a pull-down faucet which contain a counterweight assembly configured to lock and unlock the connection set easily.
To obtain the above aspects, a faucet provided by the present invention contains: a hollow body, a control assembly, an

a mixing-water outlet pipe including a first connector and a second connector, the first connector extending into the inflow portion of the hollow body to connect with the mixing valve, thus guiding the mixing water out of the mixing-water outlet pipe;
a pull hose including an inlet segment and an outlet segment, the inlet segment connecting with the second connector of the mixing-water outlet pipe, and the outlet segment entering into the inflow portion of the hollow body and extending out of the outflow portion;
a spray head being in connection with the outlet segment of the pull hose, and the spray head being removed from and fixed on the outflow portion of the hollow body; and an isolation pipe, a part of which is coupled in the hollow body, and the other part of the isolation pipe extending out of a bottom of the basin from the inflow portion of the hollow body; wherein the isolation pipe includes a channel defined therein so that the pull hose slidably moves in the isolation pipe and avoids contacting with the inlet pipe set and the mixing-water outlet pipe;
wherein the hollow body includes a first part and a second part accommodated in the first part; wherein the first part has a first cylindrical portion and an extension integrally extending from the first cylindrical portion, and the extension has a conduit defined therein;
the second part has a hollow cavity formed therein, an outlet defined around the second part and communicating with the conduit, an accommodation portion formed on a top of the second part, a receiving room defined in the accommodation portion so as to accommodate the mixing valve of the control assembly, and the inflow portion formed on a bottom of the second part, wherein the extension of the first part has the outflow portion arranged on a distal end thereof so that the outlet segment of the pull hose extends out of the outlet and the conduit from the inflow portion along the hollow cavity;
wherein a top of the isolation pipe is connected with the bottom of the second part;
wherein the second part further has a holding portion formed on the bottom thereof, and a second cylindrical portion is connected between the receiving room and the holding portion, wherein the hollow cavity is located inside the second cylindrical portion, the outlet is defined on an outer wall of the second cylindrical portion, the holding portion has a trough and a first through aperture spaced from the trough, and the second cylindrical portion has an extending flap connected on an inner wall of the hollow cavity of the second cylindrical portion, wherein the extending flap separates a distance from a top of the holding portion so as to form a defining slot; the isolation pipe includes an annular nut fixed thereon, and the annular nut has an affix protrusion formed on a top thereof so that the annular nut partially retains in the defining slot, and the affix protrusion abuts against the extending flap so as to limit the annular nut, hence the isolation pipe is inserted through the basin and the through aperture to screw with the annular nut.
9. The faucet as claimed in claim 8, wherein a decoration assembly is connected between a bottom of the hollow body and the basin.
10. The faucet as claimed in claim 8, wherein the connection set includes a screw nut, a first washer, and a second washer; the first washer has a second through aperture corresponding to a housing aperture of the basin so that the inlet pipe set, the mixing-water outlet pipe, and the isolation pipe are inserted through the second through aperture; the second washer is formed in a disk shape, and the second washer has a recessed portion, a third through aperture passing through the recessed portion so that the isolation pipe is inserted through the third through aperture, a first forcing section arranged around the third through aperture so as to push the screw nut upward, a second forcing section formed in an arc shape and extending from a top of the recessed section so as to contact with a circular area of the first washer around the second through aperture; inner threads of the screw nut screw with the outer threads of the isolation pipe, and the second washer and the first washer contact with the housing aperture of the basin, thus fixing the second part on the basin
11. The faucet as claimed in claim 10, wherein a diameter of the third through aperture of the second washer is more than the isolation pipe.
12. The faucet as claimed in claim 11, wherein a cutout is defined between the second forcing section and the first forcing section so that the inlet pipe set and the mixing-water outlet pipe are inserted through the cutout and the second through aperture respectively.
13. The faucet as claimed in claim 10 further comprising a counterweight assembly, and the counterweight assembly including a tubular coupling sleeve and a hollow block; wherein the tubular coupling sleeve is fitted on the pull hose and has a disengagement segment and an engagement segment; the hollow block is fitted to the engagement segment from the disengagement segment of the tubular coupling sleeve so that the tubular coupling sleeve is pressed to deform inwardly so as to retain on the pull hose; the hollow block has a recess formed on at least one end thereof so as to matingly engage with the screw nut, thus rotating the screw nut tightly and loosely.
