## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a shower head, and more particularly to a shower head having a closely sealing effect.
2. Description of the Related Art
A conventional shower head in accordance with the prior art is disclosed in U.S. Pat. No. 6,241,166. However, the conventional shower head has a complicated construction, thereby increasing costs of fabrication and assembly. In addition, when the bolt 38 is rotated to pull the bush 42 and the upper wall 8 upward to press the sealing ring 16, the upper wall 8 is easily deformed to reduce its diameter, thereby forming a clearance between the upper wall 8 and the spray plate 10 so that the shower head easily produces leak. Further, the spray plate 10 is integrally formed with the upper wall 8 so that the spray plate 10 cannot be removed from the upper wall 8, thereby causing inconvenience to a user when cleaning the water outlet holes of the spray plate 10. Further, the conventional shower head is not operated smoothly and does not have a constant water flow rate.

The upper portion of the mounting seat 20 is formed with an outer thread 200, and the mounting portion 22 of the mounting seat 20 is formed with an outer thread 221. The mounting portion 22 of the mounting seat 20 has a flattened face formed with at least one water inlet hole 222 communicating with an inside of the mounting seat 20 and an inside of the main body 10.
The locking nut 30 is secured on the mounting portion 22 of the mounting seat 20 and rested on the upper portion of the main body 10 to secure the mounting seat 20 on the upper portion of the main body 10. The locking nut 30 is located in the main body 10 and formed with an inner thread 31 screwed onto the outer thread 221 of the mounting portion 22 of the mounting seat 20.
The connecting disk 40 is mounted in the lower portion of the main body 10 and includes an annular disk body 41 rested on an inner wall of the main body 10, a threaded locking sleeve 43 located at a central portion of the disk body 41, and a plurality of radially arranged connecting ribs 42 mounted between the disk body 41 and the locking sleeve 43. The disk body 41 of the connecting disk 40 has a periphery formed with a radially and outwardly extended locking flange 411 and an annular groove 412 located above the locking flange 411. The locking sleeve 43 of the connecting disk 40 is formed with an inner thread 431.
The O-ring 50 is mounted between the disk body 41 of the connecting disk 40 and the inner wall of the main body 10 and located in the annular groove 412 of the disk body 41 of the connecting disk 40. The O-ring 50 has a substantially circular cross-sectional profile.
The gasket 60 is mounted on the periphery of the disk body 41 of the connecting disk 40 and enclosed around the locking flange 411 of the disk body 41 of the connecting disk 40. The gasket 60 has a substantially U-shaped cross-sectional profile having an opening directed toward the locking flange 411 of the disk body 41 of the connecting disk 40.
The water outlet faceplate 70 is mounted on a bottom of the disk body 41 of the connecting disk 40 and has a periphery formed with a substantially L-shaped clamping portion 71 pressed on the gasket 60 so that the water outlet faceplate 70 and the connecting disk 40 are combined integrally. The water outlet faceplate 70 has a substantially convex cross-sectional profile and has a surface formed with a plurality of water outlet holes 72 each communicating with the inside of the main body 10 and each provided with a nozzle 73.
The adjusting bolt 80 is rotatably mounted in the mounting seat 20 and has a distal end extended through the mounting portion 22 of the mounting seat 20 and screwed into the inner thread 431 of the locking sleeve 43 of the connecting disk 40. The adjusting bolt 80 has a bolt head 82 rotatably mounted in the mounting portion 22 of the mounting seat 20 and rested on a stepped bottom of the mounting portion 22 of the mounting seat 20.

In assembly, the distal end of the adjusting bolt 80 is screwed into the inner thread 431 of the locking sleeve 43 of the connecting disk 40 so that when the adjusting bolt 80 is rotated relative to the locking sleeve 43 of the connecting disk 40, the locking sleeve 43 of the connecting disk 40 is moved axially toward the main body 10 by rotation of the adjusting bolt 80. Thus, the O-ring 50 is moved upward with the disk body 41 of the connecting disk 40 and closely urged on the inner wall of the main body 10, thereby forming a closely sealing effect between the disk body 41 of the connecting disk 40 and the inner wall of the main body 10.
When in use, referring to FIG. 5, the universal connector 92 of the connector unit 90 is connected to a wall pipe to introduce the water from the wall pipe into the mounting seat 20. Then, the water flows through the water inlet hole 222 of the mounting seat 20 into the inside of the main body 10, then passes through the connecting ribs 42 of the connecting disk 40 and is finally injected outward from the water outlet holes 72 of the water outlet faceplate 70 for use with a user.
Accordingly, 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. In addition, the gasket is enclosed around the locking flange of the disk body of the connecting disk and the clamping portion of the water outlet faceplate is pressed on the gasket so that the water outlet faceplate and the connecting disk are combined integrally. Further, the user only needs to rotate the adjusting bolt to move the connecting disk and the water outlet faceplate toward the main body, thereby facilitating the user adjusting the tension between the water outlet faceplate and the main body. Further, the connecting disk and the water outlet faceplate are removed from the main body by unscrewing the adjusting bolt, thereby facilitating the user cleaning the water outlet holes of the water outlet faceplate. Further, the water is directly injected outward from the water outlet holes of the water outlet faceplate for use with a user, so that the shower head is operated smoothly and has a constant water flow rate. Further, the connecting disk is integrally formed with the locking sleeve, thereby decreasing costs of fabrication, and thereby simplifying the process of assembly.
Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention.
