Description
OUTLET PIPE STRUCTURE OF A FAUCET
FIELD OF THE INVENTION
The present invention relates to an outlet pipe structure of a faucet.
BACKGROUND OF THE INVENTION
Conventional outlet pipe of a faucet is cast molded from copper material, so its production cost is high.
CN Publication No. 201606557U discloses that a composite faucet is comprised of a filler body and a housing, but such a structure is not applied in an outlet pipe of a faucet. However, it is difficult to machine the filler body of the composite faucet so as to form an inlet, an outlet, and a channel. Also, the machining cost is high.
In addition, the channel has a channel tube inserted therein, but it cannot be embodied. Due to a flexible pipe or a plastic pipe is flexible, two ends of the flexible pipe or the plastic pipe cannot connect with the inlet and the outlet, thus leaking water and dropping easily. If the copper pipe or an aluminum pipe is used as the outlet pipe of the faucet, it is easy to be fixed, yet its flexibility is too poor to insert into a curved channel. Likewise, an opening of the filler body screws with a threaded connector, but the filler body is made of cements, calcium carbonates or gypsums, so the threaded connector looses easily, thus leaking water.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
SUMMARY OF THE INVENTION
One aspect of the present invention provides an outlet pipe structure of a faucet which is capable of overcoming the shortcomings of the conventional outlet pipe structure of the faucet.
To obtain this, an outlet pipe structure of a faucet provided by the present invention contains:
a metal tube including a first segment, a second segment, and a channel communicating with the first segment and the second segment; the first segment having a first recess defined on an inner wall thereof adjacent to a first opening; and the second segment having a pedestal disposed on a peripheral side of a second opening;
a hose assembly including a hose having a passage, an inlet end, and an outlet end; an inlet connector connected with the inlet end and having at least one locking block mounted on an outer wall of the inlet connector; an outlet connector coupled with the outlet end and having at least one boss arranged around an outer wall of the outlet connector; the hose assembly being inserted from the first segment of the metal tube such that the outlet connector reaches to the second segment via the channel, and one of the at least one boss retains in the first recess so that the hose assembly is fixed in the metal tube;
a seat including a first slot, a second slot, a connecting orifice communicating with the first slot and the second slot; the connecting orifice having at least one trough defined on an inner wall thereof and having two opposite retaining faces formed on one side of the seat relative to the second slot; the at least one locking block passing through the at least one trough and retaining with the two opposite retaining faces after the seat rotates a predetermined degrees, such that the seat is fixed on the inlet connector of the hose assembly; the seat also including at least one coupling tab formed on an outer wall thereof and coupling with the pedestal of the second segment after the seat is fixed.
The outlet pipe structure of the faucet further contains two bolts, the pedestal of the second segment of the metal tube having two screwing holes; the seat also including two coupling tabs formed on the outer wall thereof, and each coupling tab having an aperture; each bolt screwing with a respective one of the two = screwing holes of the pedestal via the aperture of the each coupling tab, such that the seat is screwed with the pedestal of the metal tube.
The inlet connector has two locking blocks symmetrically mounted the outer wall thereof; the connecting orifice has two troughs symmetrically defined on the inner wall thereof so as to insert the two locking blocks and to retain with the two opposite retaining faces after the seat rotates 90 degrees clockwisely or anticlockwisely.
The outlet connector has four bosses isometrically arranged around the outer wall thereof so that one of the four bosses retains in the first recess.
The inlet connector also has a tunnel defined therein, an upper inserting portion and a lower inserting portion formed on the outer wall of the inlet connector, and a stopping rib defined between the upper inserting portion and the lower inserting portion; the upper inserting portion is inserted onto the inlet end of the hose assembly; the lower inserting portion is inserted into the first slot of the seat; and the stopping rib abuts against an end wall of the inlet end and an end wall of the seat; the at least one locking block of the inlet connector is located at a bottom end of the lower inserting portion.
The lower inserting portion has two grooves defined on the outer wall thereof so as to retain with two sealing rings.
The outlet connector also has a passageway deformed therein, a mount formed on the outer wall of the outlet connector, an insertion section with a small diameter extending outwardly from the mount; a stop fence arranged on a connection of the mount and the insertion section; the insertion section is inserted to the outlet end of the hose and is abutted by the stop fence and an end wall of the outlet end; the at least one boss of the outlet connector is arranged around the outer wall of the mount.
The hose, the inlet connector, and the outlet connector are integrally formed from plastic material.
Thereby, in assembly, the inlet connector of the hose assembly is inserted to the second segment from the first segment through the channel, and then the four bosses of the outlet connector retain in the first recesses of the first segment so that the hose assembly does not disengage from the metal tube, such that the inlet connector of the hose assembly is inserted into the seat, and then the seat is rotated 90 degrees so that two apertures of the seat align with the two screwing holes of the pedestal of the metal tube.
Due to the two locking blocks of the inlet connector retain with the two opposite retaining faces of the seat, the seat is fixed on the inlet connector of the hose assembly securely so that the two bolts screw with the two screwing holes via the two apertures, thus finishing assembly easily and quickly.
The hose assembly connects with the seat securely so that the metal tube is isolated completely without contacting water, hence the metal tube is made of zinc alloy material instead of copper material. Also, the hose assembly and the seat are made of plastic material so as to avoid lead extraction in a faucet, to prevent from lead pollution, and to reduce material cost.
In addition, the hose assembly and the seat are integrally formed from plastic material so as to reduce material cost, to prevent from lead pollution, and to enhance production efficiency.

The hose assembly 20 connects with the seat 30 securely so that the metal tube 10 is isolated completely without contacting water, hence the metal tube 10 is made of zinc alloy material instead of copper material. Also, the hose assembly 20 and the seat 30 are made of plastic material so as to avoid lead extraction in a faucet, to prevent from lead pollution, and to reduce material cost In addition, the hose assembly 20 and the seat 30 are integrally formed from plastic material so as to reduce material cost, to prevent from lead pollution, and to enhance production efficiency.
