Abstract:
1. A multi-functional switching apparatus for bathroom showers, comprising a set of first and second control valves, a set of first and second adjusting valve units, a set of first and second control valve spindle units, and a set of first and second handle units wherein the first and the second control valves are respectively provided with an upper end having an insert recess preset at the edge thereon and a receiving chamber with external screw threads defining the outer periphery thereon; the first control valve having a set of cold and hot water inlet tubes symmetrically extending at preset positions of both lateral sides thereon, and one side equipped with a connecting portion with a screw hole defined thereon for the registration of a screw element therewith wherein the connecting portion has a flow passage defined therein to communicate with the receiving chamber thereby, and the receiving chamber has a set of water inlets symmetrically defining the appropriate positions of the bottom side to fluidly associate with cold and hot water inlet tubes; the second control valve having a plurality of water intake ports disposed at the bottom end of the receiving chamber thereon to communicate with a plurality of water outlet ducts respectively, the first and second adjusting valve units being respectively composed of an upper valve, a watertight ring, a lower valve, and a coupling hoop; the first adjusting valve unit also includes a packing piece and the second adjusting valve unit also has a positioning collar wherein each upper valve of the first and second adjusting valve units has an accommodating groove defined therein for the accommodation of the watertight ring therein, a restricting element protruding at one side thereon, a stop flange preset at a lower step of the accommodating groove thereon, and an insert block extending at the outer periphery of one side thereon; the upper valve of the second adjusting valve unit also having an upper end defined by an indented cavity with a plurality of ribs annularly arranged therein for the abutting location of the positioning collar thereby; each lower valve of the first and second adjusting valve units having a positioning upper end to form a retaining space thereon for the engagement of the coupling hoop therewith wherein the lower valve of the first adjusting valve unit has a water intake port disposed at the lower end thereon and a plurality of protrusions annularly extending at the bottom edge thereon to define a plurality of conjoining sections for secure connection of insert hooks of the matched packing piece therewith, and the packing piece has a set of water intakes symmetrically disposed at appropriate positions thereon; the lower valve of the second adjusting valve unit has a water intake orifice disposed at the bottom side thereon; the first and second control valve spindle units being respectively equipped with a first valve spindle and a second valve spindle wherein the first valve spindle has an adjusting device mounted thereto, and the adjusting device is made up of a central bore defined by a connecting section thereon, and a limiting block protruding at one side thereof; the first and second handle units being respectively equipped with a fixed cover, a cover seat, and a cap; the first handle unit also includes a handle, and the second handle unit also has a cross-shaped grip wherein each of the fixed covers and the cover seats is formed in a hollow tubular shape with internal screw threads defining the inner surface thereon respectively; each of the cover seats has a set of locking portions symmetrically disposed at the bottom surface; each of the caps has an external screw-threaded section defining the outer surface, an inner threaded section disposed at the internal bottom edge thereon, and a central insert hole extending in the middle there-through; the handle and the cross-shaped grip being respectively provided with an insert opening, a screw hole and a matched screw element; characterized by that; the second control valve having a coupling portion extending at one side wherein a flow-passing channel is disposed defining the coupling portion therein; each upper valve of the first and second adjusting valve units having an opening disposed therein to communicate with the accommodating groove thereof for the extension of the first and second valve stems there-through respectively; each lower valve having a fitting groove with a screw hole preset at appropriate positions thereon, and a screw element matched to the screw hole; the second adjusting valve unit having a positioning collar mounted thereto, and the first and the second control valve spindle units being respectively equipped with the first valve spindle and the second valve spindle; the first control valve spindle unit having the adjusting device mounted thereto wherein on one side of the adjusting device is disposed a limiting block with inner screw threads defined therein for the registration of a matched screw shaft therewith; the second control valve spindle unit having a water-switching device mounted thereto; each fixed cover of the first and second handle units has a plurality of regulating slots annularly arranged at preset positions thereon; wherein, the present invention can achieve more flexible and convenient application, and provide multiple functions.
