The hidden forward switching angle valve device as claimed in claim 7, further comprising an intermediate connection tube, wherein said intermediate connection tube communicates said valve core and said fixed seat, and when the left end of said inner nipple is protruded out of said fixed sleeve, said water passage hole communicates with said intermediate connection tube.

9. The concealed forward angle valve apparatus of claim 1, wherein the water inlet pipe is perpendicular to the switch assembly and the water outlet pipe assembly, and is integrally F-shaped.

10. The concealed forward switching angle valve device as set forth in claim 1, wherein the case includes a main body and a flap detachably attached to an upper side and/or a lower side of the main body, the side opening is formed on the flap, and the first and second positive openings are formed on the main body.
