Abstract

A positioning structure of a water supply hose for a pull-out faucet contains: a faucet body including an outlet; a water supply hose accommodated in the faucet body so as to supply water and including an outlet segment; a spraying head connected with the outlet segment of the water supply hose and being pulled outwardly and retracted inwardly with the water supply hose; a magnetic attraction device including a first connecting member and a second connecting member which magnetically attract with each other. The first connecting member is disposed in the outlet, the second connecting member is mounted on an outlet segment, the second connecting member retracts back to its original position with the water supply hose and the spraying head and moves into the outlet so as to magnetically attract with the first connecting member, hence the water supply hose and the spraying head are magnetically attracted and fixed.

First claim

What is claimed is:

1. A positioning structure of a water supply hose for a pull-out faucet comprising:
a faucet body including an outlet;
a water supply hose accommodated in the faucet body so as to supply water and including an outlet segment;
a spraying head connected with the outlet segment of the water supply hose and being pulled outwardly and retracted inwardly with the water supply hose by a user;
a magnetic attraction device including a first connecting member and a second connecting member which magnetically attract with each other; the first connecting member being disposed in the outlet of the faucet body; the second connecting member being mounted on the outlet segment of the water supply hose; the second connecting member retracting back to its original position with the water supply hose and the spraying head and moving into the outlet of the faucet body so as to magnetically attract with the first connecting member, hence the water supply hose and the spraying head are magnetically attracted and fixed;
wherein the first connecting member has a first attracting element, and the second connecting member has a second attracting element for magnetically attracting with the first attracting element;
wherein the outlet segment of the water supply hose has a limiting sleeve, and the limiting sleeve has an annular recess formed around an outer wall thereof, the annular recess has an upper fringe and a lower fringe which are arranged on two ends of the annular recess; the second connecting member has an inner retainer and an outer retainer; wherein the inner retainer is formed in a C shape and has two first free segments flexibly expanding to retain with an outer wall of the annular recess and to be limited between the upper fringe and the lower fringe; the second attracting element is a magnet and is formed in a C shape, the second attracting element has two second free segments flexibly expanding to retain with the outer wall of the annular recess and to be limited between the upper fringe and the inner retainer; the outer retainer is fitted above the limiting sleeve from the outlet segment of the water supply hose and then is moved downwardly so that the inner retainer and the second attracting element are limited in the outer retainer, such that the outer retainer is limited by the inner retainer to move downwardly and is restricted by the second attracting element to move upwardly.

2. The positioning structure of the water supply hose for the pull-out faucet as claimed in claim 1 , characterized in that the inner retainer has a protrusion arranged on a top end thereof and two stepped faces located on two sides of the protrusion; a top end of the protrusion abuts against the upper fringe of the annular recess; a bottom end of the second attracting element contacts with the two stepped faces of the inner retainer, and the two second free segments of the second attracting element abut against two sides of the protrusion.

3. The positioning structure of the water supply hose for the pull-out faucet as claimed in claim 1 , wherein the inner retainer also has a stopping rib arranged around an peripheral side of a bottom end thereof so as to abut against a bottom end of the outer retainer, thereby limiting the outer retainer to move downwardly; the outer retainer has a hooked projection extending outwardly from an inner wall thereof, such that when the outer retainer moves downwardly, the hooked projection passes through the second attracting element to hook the bottom end of the second attracting element, thus limiting the outer retainer to move upwardly.

4. The positioning structure of the water supply hose for the pull-out faucet as claimed in claim 1 , wherein the first attracting element is a magnet and is circular, the first attracting element has an orifice defined thereon; the second attracting element is a magnetically attractive material and is moved close to the orifice so as to magnetically attract with the first attracting element.

5. A positioning structure of a water supply hose for a pull-out faucet comprising:
a faucet body including an outlet;
a water supply hose accommodated in the faucet body so as to supply water and including an outlet segment;
a spraying head connected with the outlet segment of the water supply hose and being pulled outwardly and retracted inwardly with the water supply hose by a user;
a magnetic attraction device including a first connecting member and a second connecting member which magnetically attract with each other; the first connecting member being disposed in the outlet of the faucet body; the second connecting member being mounted on the outlet segment of the water supply hose; the second connecting member retracting back to its original position with the water supply hose and the spraying head and moving into the outlet of the faucet body so as to magnetically attract with the first connecting member, hence the water supply hose and the spraying head are magnetically attracted and fixed;
wherein the first connecting member has a first attracting element, and the second connecting member has a second attracting element for magnetically attracting with the first attracting element;
wherein the outlet segment of the water supply hose has a limiting sleeve; the second connecting member further has a guiding sheath applied to accommodate the second attracting element and fixed on the limiting sleeve of the water supply hose;
wherein the guiding sheath has two symmetrically hollow casings for covering an outer wall of the limiting sleeve.

6. The positioning structure of the water supply hose for the pull-out faucet as claimed in claim 5 , wherein the guiding sheath has a positioning trench defined around an outer wall thereof; the second attracting element is formed in a C shape, such that the second attracting element is flexibly retained in the positioning trench of the guiding sheath, and the second attracting element is a magnetically attractive material, the first attracting element is a magnet.

7. The positioning structure of the water supply hose for the pull-out faucet as claimed in claim 5 , wherein the outlet segment of the water supply hose further has a connector, between the connector and the limiting sleeve is defined an annular groove, the guiding sheath has a tab extending outwardly around an inner wall thereof so as to retain with the annular groove of the water supply hose, thus limiting the guiding sheath to move along the limiting sleeve.

8. The positioning structure of the water supply hose for the pull-out faucet as claimed in claim 5 , wherein the first attracting element is a magnet and is circular, and the first attracting element has an orifice defined thereon; the second attracting element is a magnetically attractive element and is moved into the orifice so as to magnetically attract with the first attracting element;
wherein the guiding sheath has an internal segment, an external segment, and a conical guide face formed on an outer wall thereof adjacent to the internal segment so as to guide the guiding sheath to fit into the orifice of the first attracting element, such that the second attracting element on the guiding sheath faces to and magnetically attracts with the first attracting element;
wherein the guiding sheath further has a positioning trench defined around the outer wall thereof; the second attracting element is formed in a C shape, such that before connecting the guiding sheath, the second attracting element is fitted on the limiting sleeve of the water supply hose and then is moved downwardly so that the second attracting element is guided to move into the positioning trench by using the conical guide face of the guiding sheath, thus retaining the second attracting el
