DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 through FIG. 6 shows a preferred embodiment of the present invention.
A button switching type handheld shower head comprises a body 1, a panel 2, a water diversion seat 3, a water diversion body 4, a switching shaft 5, a switching sheet 6, a spring 7, a connecting piece 8, a turning sheet 9, and a button 10.
In order to assemble the components conveniently, the body 1 is formed with a body front lid 11. The body front lid 11 and the body 1 are assembled to form a handle. An inlet tube 12 is provided and installed in the handle.
The water diversion seat 3 is installed between the body 1 and the panel 2. The water diversion seat 3 has functional water channels corresponding to functional water outlets of the panel 2, which has the same configuration as a common multi-function shower head.
The water diversion body 4 is installed at a side of the water diversion seat 3, which has the same configuration as a common multi-function shower head. The water diversion body 4 is formed with functional water diversion holes 41 corresponding to the functional water channels of the water diversion seat 3 for switching the water route conveniently. The water diversion body 4 has a center hole 42. An inner wall of the center hole 42 of the water diversion body 4 is formed with a guiding groove 43 and a bevel 44.
A front end of a switching shaft 5 is inserted into the center hole 42 of the water diversion body 4. The switching shaft 5 is formed with a first guiding bar 51 thereon to match with the guiding groove 43.
The switching sheet 6 and the spring 7 are sleeved on the switching shaft 5. The switching sheet 6 is attached to a side of the water diversion body 4 by means of the elasticity of the spring 7. The switching sheet 6 is formed with a switching hole 61. The switch sheet 6 can be turned to align the switching hole 61 with one of the functional water diversion holes (41) for switching the water route. The center of the switching sheet 6 is formed with a second guiding bar 62 to match with the guiding groove 43. The second guiding bar 62 is formed with a guiding bevel 63 corresponding to the bevel 44. For a precise switch operation, one side of the switching shaft 5, close to the water diversion body 4, is formed with first axial teeth 52, and one side of the switching sheet 6, close to the water diversion body 4, is formed with second axial teeth 62. The first axial teeth 52 mesh with the second axial teeth 64, such that the switching sheet 6 is radially positioned on the switching shaft 5.
A front end of the connecting piece 8 is connected with a rear end of the switching shaft 5. A rear end of the connecting piece 8 is connected with an executing end of the turning sheet 9. The turning sheet 9 is pivoted in the body 1 (or the inlet tube 12). An operation end 92 of the turning sheet 9 right faces the top of the button 10. For a precise and stable transmission, the turning sheet 9 has an L shape. The L-shaped turning sheet 9 has an angled portion pivoted on the body 1 or the inlet tube 12. The operation end 92 of the L-shaped turning sheet 9 right faces the top of the button 10. The executing end 91 of the L-shaped turning sheet 9 is inserted and connected to the rear end of the connecting piece 8. The front end of the connecting piece 8 is formed two forked pieces 81. The two forked pieces 81 are configured to clamp two sides of the rear end of the switching shaft 5 and pivotally connected with the switching shaft 5.
The button 10 is installed on the handle of the body 1 and extends out of the body 1. In this embodiment, the body front lid 11 and the inlet tube 12 are formed with installation holes 13, 14. The button 10 is installed in the two installation holes 13, 14. A lower end of the button 10 is exposed out of the installation hole 13 of the body front lid 11, and an upper end of the button 10 is inserted into the installation hole 14 of the inlet tube 12. For a stable and precise transmission, the body 1 or the inlet tube 12 is provided with a press member 15. The press member 15 has a U shape. The press member 15 is located between the button 10 and the turning sheet 9. The operation end 92 of the turning sheet 9 right faces the center of the U-shaped press member 15. The center of the top of the button 10 is provided with a push plate 101 inserted in the center of the U-shaped press member 15. The push plate 101 right faces the operation end 92 of the turning sheet 9.
During use, when the button 10 is not pressed, under the action of the spring 7, the switching shaft 5 and the switching sheet 6 are moved forward. The first guiding bar 51 and the second guiding bar 62 are matched with the guiding groove 43. The water diversion body 4 and the switching shaft 5 are radially positioned to the switching sheet 6. The switching hole 61 of the switching sheet 6 is aligned with one or two functional water diversion holes 41 of the water diversion body 4 for a corresponding functional discharging.
If the user wants to switch the outflow function, the button 10 is pressed to turn the turning sheet 9. The switching shaft 5 and the switching sheet 6 are driven by the connecting piece 8 to compress the spring 7 to move rearward. The second guiding bar 62 of the switching sheet 6 is moved out of the guiding groove 43. The switching hole 61 of the switching sheet 6 is moved away from the initial aligned water diversion hole 41. The button 10 is released. The switching shaft 5 and the switching sheet 6, under the restoring force of the spring 7, are moved forward. The guiding bevel 63 of the second guiding bar 62 of the switching sheet 6 cooperates with the bevel 44 of the center hole 42 of the water diversion body 4. With the aid of water pressure, the switching sheet 6 is turned a corresponding angle, and the second guiding bar 62 cooperates with the guiding groove 43 again. At this time, the switching hole 61 of the switching sheet 6 is aligned with another water diversion hole 61 for switching a different function.
Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
