Abstract

A faucet includes a faucet body, a bent tube mounted on the faucet body, a water outlet pipe retractably mounted in the bent tube and having a connector, an elastic sleeve mounted in the distal end of the bent tube, a first magnetic member mounted in the elastic sleeve, a locking sleeve mounted on the connector of the water outlet pipe and inserted into the elastic sleeve, a second magnetic member mounted in the locking sleeve and movable to approach the first magnetic member, and a spout locked onto the locking sleeve. Thus, when the locking sleeve is inserted into the elastic sleeve, the second magnetic member is attracted magnetically by the first magnetic member so as to position the locking sleeve in the elastic sleeve and to position the spout onto the distal end of the bent tube.

Claims

1. A faucet, comprising:

a faucet body;

a bent tube mounted on the faucet body;

a flexible water outlet pipe retractably mounted in the bent tube and having a distal end provided with a connector protruding outwardly from a distal end of the bent tube;

an elastic sleeve mounted in the distal end of the bent tube;

a first magnetic member mounted in the elastic sleeve;

a locking sleeve mounted on the connector of the water outlet pipe and detachably inserted into the elastic sleeve;

a second magnetic member mounted in the locking sleeve to move in concert with the locking sleeve and movable to approach the first magnetic member so that the second magnetic member is attracted magnetically by the first magnetic member to attach the locking sleeve to the elastic sleeve; and

a spout locked onto the locking sleeve and having an inner portion formed with a water inlet port connected to the connector of the water outlet pipe to connect the spout to the water outlet pipe.

2. The faucet of claim 1, wherein

the bent tube has an inner portion formed with a receiving chamber to receive the water outlet pipe;

the elastic sleeve has an inner portion formed with a receiving space to receive the locking sleeve and to allow passage of the water outlet pipe;

the receiving space of the elastic sleeve has a peripheral wall provided with a stepped stop shoulder to stop the first magnetic member;

the stop shoulder of the elastic sleeve has a side provided with a locking lug;

the first magnetic member is secured in the receiving space of the elastic sleeve and abuts the stop shoulder of the elastic sleeve;

the first magnetic member has an outer wall formed with a locking recess locked onto the locking lug of the stop shoulder to lock the first magnetic member in the receiving space of the elastic sleeve;

the locking sleeve has an inner portion formed with a mounting chamber mounted on the connector of the water outlet pipe;

the mounting chamber of the locking sleeve has a peripheral wall provided with an inner thread;

the second magnetic member is received in the mounting chamber of the locking sleeve and is sandwiched between the locking sleeve and the connector of the water outlet pipe;

the spout has a top provided with an outer thread screwed into the inner thread of the locking sleeve.

3. The faucet of claim 2, wherein

the locking sleeve has a top formed with a reduced through hole to allow passage of the connector of the water outlet pipe;

the through hole of the locking sleeve is connected to and has a diameter smaller than that of the mounting chamber;

the second magnetic member has an outer diameter greater than the diameter of the through hole of the locking sleeve.

4. The faucet of claim 2, wherein the connector of the water outlet pipe in turn extends through the first magnetic member, the receiving space of the elastic sleeve, the mounting chamber of the locking sleeve and the second magnetic member.

5. The faucet of claim 1, wherein the connector of the water outlet pipe is inserted into the water inlet port of the spout.

6. The faucet of claim 1, wherein

the distal end of the bent tube has an open end portion formed with an opening;

the elastic sleeve has a periphery provided with a protrusion inserted into the opening of the bent tube.

7. The faucet of claim 6, wherein

the protrusion of the elastic sleeve has a bottom formed with a depression;

the spout has a periphery provided with a boss inserted into the depression of the protrusion.

8. The faucet of claim 2, wherein the elastic sleeve has an outer wall provided with an annular stop flange protruding from the receiving chamber of the bent tube and abutting the distal end of the bent tube.

9. The faucet of claim 1, wherein

the distal end of the bent tube has a surface formed with a locking hole;

the elastic sleeve has a surface provided with a flexible locking stub locked in the locking hole of the bent tube.

10. The faucet of claim 1, wherein the north pole (N) of the first magnetic member faces and aligns with the south pole (S) of the second magnetic member so that the second magnetic member is attracted magnetically by the first magnetic member.

11. The faucet of claim 1, wherein the south pole (S) of the first magnetic member faces and aligns with the north pole (N) of the second magnetic member so that the second magnetic member is attracted magnetically by the first magnetic member.

12. The faucet of claim 5, wherein

the connector of the water outlet pipe has an outer periphery provided with a plurality of sealing rings;

the sealing rings of the water outlet pipe presses a peripheral wall of the water inlet port of the spout to provide an air-tight effect between the water outlet pipe and the spout.

13. The faucet of claim 1, wherein the bent tube has a curved shape.

14. The faucet of claim 1, wherein the first magnetic member has an annular shape.

15. The faucet of claim 1, wherein the second magnetic member has an annular shape.

16. The faucet of claim 2, wherein the locking sleeve is detachably inserted into the receiving space of the elastic sleeve.

17. The faucet of claim 2, wherein the elastic sleeve is mounted in the receiving chamber of the bent tube and is attached to the distal end of the bent tube.

18. The faucet of claim 2, wherein the outer thread of the spout is received in the mounting chamber of the locking sleeve.

19. The faucet of claim 2, wherein the water outlet pipe is movable in the receiving chamber of the bent tube.

20. The faucet of claim 2, wherein the connector of the water outlet pipe is movable to protrude outwardly from the receiving chamber of the bent tube.
