Shower head structure

[0002] 1. Field of the Invention

[0003] The present invention relates to a shower head structure, and more particularly to a shower head structure, wherein the user can operate the push button by his one hand only, so as to switch and adjust the water flow, thereby facilitating the user switching and adjusting the water flow of the shower head structure.

[0004] 2. Description of the Related Art

[0005] A conventional shower head in accordance with the prior art comprises a flow switch disk, and a water outlet panel. In operation, the flow switch disk is used to switch the water flow flowing through the water outlet panel, thereby achieving a multi-stage water flow. However, the user has to hold the shower head by his one hand, and to rotate the water outlet panel by his other hand, so as to switch the water flow, thereby causing inconvenience to the user in adjustment of the shower head.

[0006] The present invention has arisen to mitigate and/or obviate the disadvantage of the conventional shower head.

[0007] The primary objective of the present invention is to provide a shower head structure, wherein the user can operate the push button by his one hand only, so as to switch and adjust the water flow, thereby facilitating the user switching and adjusting the water flow of the shower head.

[0026] The water guide member 40 is mounted in the seat 21 of the front housing 20 and has a disk shape. The water guide member 40 has a center formed with a hole 41. A locking screw 42 is extended through the hole 41 of the water guide member 40, and is screwed into the fixing seat 16 of the body 10, thereby securing the water guide member 40 on the body 10. The water guide member 40 has a surface formed with a plurality of water outlet holes 43. The water guide member 40 has a periphery formed with a receiving recess 44 for receiving a third compression spring 45 and a positioning block 46, wherein the third compression spring 45 is urged between the positioning block 46 and a wall of the receiving recess 44 of the water guide member 40. The water guide member 40 has a side formed with a protruding lug 47 inserted into the annular flange 13 of the body 10. A waterproof O-ring 48 is mounted between the protruding lug 47 of the water guide member 40 and the annular flange 13 of the body 10.

[0027] The flow switch disk 50 is rotatably mounted on the water guide member 40. The flow switch disk 50 is formed with a protruding flange 51 rested on the surface of the water guide member 40. Two semi-circular snapping members 52 are mounted on the protruding flange 51 of the flow switch disk 50, for locking the flow switch disk 50 on the water guide member 40. The flow switch disk 50 has a surface formed with a plurality of holes 53 each having a periphery provided with a waterproof gasket 54. Preferably, the holes 53 in the flow switch disk 50 are located at different positions. The flow switch disk 50 has a first side formed with a plurality of concave portions 55 (see FIG. 3) for insertion of the positioning block 46 of the water guide member 40.

The threaded seat 71 of the second water outlet panel 70 has a wall formed with a hole 72. A locking screw 73 is extended through the hole 72 of the threaded seat 71 of the second water outlet panel 70, and is screwed into the fixing seat 56 of the flow switch disk 50, thereby securing the second water outlet panel 70 on the flow switch disk 50.

[0030] The third water outlet panel 80 is mounted on the second water outlet panel 70, and is formed with an outer threaded section 82 screwed into the threaded seat 71 of the second water outlet panel 70. A waterproof O-ring 81 is mounted between the third water outlet panel 80, and the second water outlet panel 70.

[0031] In operation, referring to FIGS. 1-5, the water guide member 40 introduces and guides the water flow into the flow switch disk 50. The user can press and push the push button 30, so that the wedge-shaped block 35 of the push button 30 pushes and moves the ratchet teeth 57 of the flow switch disk 50, thereby forcing the flow switch disk 50 to rotate. At this time, the holes 53 in the flow switch disk 50 located at different positions are rotated with the flow switch disk 50 to align with the first water outlet panel 60, the second water outlet panel 70 and the third water outlet panel 80 respectively, thereby switching the water flow.

[0032] Accordingly, the user can operate the push button 30 by his one hand only, so as to switch and adjust the water flow through the first water outlet panel 60, the second water outlet panel 70 and the third water outlet panel 80, thereby facilitating the user switching and adjusting the water flow, and thereby enhancing the versatility of the shower head.
