Abstract

A shower head includes a main body, a mounting seat, a locking nut, a connecting disk, an O-ring, a gasket, a water outlet faceplate, an adjusting bolt, and a connector unit. Thus, the connecting disk is moved toward the main body by rotation of the adjusting bolt so that the O-ring is moved upward with the connecting disk and closely urged on the inner wall of the main body, thereby forming a closely sealing effect between the connecting disk and the inner wall of the main body.

Claims

1. A shower head, comprising:

a main body having a closed upper portion and an open lower portion;

a connecting disk mounted in the lower portion of the main body;

an O-ring mounted between the connecting disk and an inner wall of the main body;

a water outlet faceplate mounted on and combined with the connecting disk integrally;

wherein the connecting disk includes an annular disk body rested on the inner wall of the main body and having a periphery formed with a radially and outwardly extended locking flange and an annular groove located above the locking flange.

2. The shower head in accordance with claim 1, wherein the connecting disk further includes a locking sleeve located at a central portion of the disk body and formed with an inner thread.

3. The shower head in accordance with claim 2, wherein the connecting disk further includes a plurality of radially arranged connecting ribs mounted between the disk body and the locking sleeve.

4. The shower head in accordance with claim 1, wherein the O-ring is mounted between the disk body of the connecting disk and the inner wall of the main body and located in the annular groove of the disk body of the connecting disk.

5. The shower head in accordance with claim 1, wherein the O-ring has a substantially circular cross-sectional profile.

6. The shower head in accordance with claim 1, further comprising a gasket mounted on the periphery of the disk body of the connecting disk and enclosed around the locking flange of the disk body of the connecting disk.

7. The shower head in accordance with claim 6, wherein the gasket has a substantially U-shaped cross-sectional profile having an opening directed toward the locking flange of the disk body of the connecting disk.

8. The shower head in accordance with claim 6, wherein the water outlet faceplate is mounted on a bottom of the disk body of the connecting disk and has a periphery formed with a clamping portion pressed on the gasket so that the water outlet faceplate and the connecting disk are combined integrally.

9. The shower head in accordance with claim 8, wherein the clamping portion of the water outlet faceplate is substantially L-shaped.

10. The shower head in accordance with claim 1, wherein the water outlet faceplate has a substantially convex cross-sectional profile.

11. The shower head in accordance with claim 1, wherein the water outlet faceplate has a surface formed with a plurality of water outlet holes each communicating with the inside of the main body and each provided with a nozzle.

12. The shower head in accordance with claim 2, further comprising:

a mounting seat secured on the upper portion of the main body and having an upper portion protruding outward from the main body and a lower end formed with a mounting portion;

a locking nut secured on the mounting portion of the mounting seat and rested on the upper portion of the main body to secure the mounting seat on the upper portion of the main body;

an adjusting bolt rotatably mounted in the mounting seat and having a distal end extended through the mounting portion of the mounting seat and screwed into the inner thread of the locking sleeve of the connecting disk.

13. The shower head in accordance with claim 12, wherein:

the upper portion of the main body is formed with a circular recess having a bottom face formed with a substantially square chamfered positioning hole;

the mounting portion of the mounting seat is secured in the positioning hole of the main body and formed with an outer thread;

the locking nut is located in the main body and formed with an inner thread screwed onto the outer thread of the mounting portion of the mounting seat;

the adjusting bolt has a bolt head rotatably mounted in the mounting portion of the mounting seat and rested on a stepped bottom of the mounting portion of the mounting seat.

14. The shower head in accordance with claim 12, wherein the mounting seat has a mediate portion formed with an outward extended substantially arc-shaped resting flange rested on the upper portion of the main body.

15. The shower head in accordance with claim 12, wherein the connecting disk is moved toward the main body by rotation of the adjusting bolt so that the O-ring is moved upward with the connecting disk and urged on the inner wall of the main body, thereby forming a closely sealing effect between the connecting disk and the inner wall of the main body.

16. The shower head in accordance with claim 2, wherein the connecting disk is integrally formed with the locking sleeve.

17. The shower head in accordance with claim 1, wherein the main body has a bell shape.

18. The shower head in accordance with claim 12, wherein the mounting portion of the mounting seat has a substantially square chamfered shape.

19. The shower head in accordance with claim 12, wherein the mounting portion of the mounting seat has a flattened face formed with at least one water inlet hole communicating with an inside of the mounting seat and an inside of the main body.
