1. A light-detector, hand-controlled faucet with water temperature regulator comprising in combination:

  • (a) a cross-type manifold having an end which can be connected to a source of water, said source including a pipe for supplying hot water and a pipe for supplying cool water;

    said manifold also having a tubular transverse portion for mounting in it a respective cylindrical valve control post, said tubular transverse portion including a first walled selector slot, said tubular transverse portion including a water outlet, and said water outlet including a circular pipe coupling, and said tubular transverse portion including a valve aperture including a tubular projection and a circular, walled valve-connecting opening;

    said manifold having a water temperature control section for mounting in it a respective cylindrical water temperature control post, said water temperature control section having a first end adapted to communicate with the hot water pipe and the cool water pipe, and said water temperature control section including a second walled slot at the end thereof which is opposite from said end adapted to communicate with the hot water pipe and the cool water pipe;

    said manifold having a mixed water outlet positioned in communication at the hot water pipe; and

    said manifold having an electric wire conduit extending from the space between said circular pipe coupling and said water outlet to the respective lateral end surface near said circular valve-connecting opening of the transverse section of said manifold;

    (b) a circular tie ring with a circular protuberance around its center and a tubular water pressure pipe at its peripheral surface, said circular tie ring being adapted to be operatively seated in said circular valve-connecting opening of said manifold;

    (c) a pliable valve sleeve, said pliable valve seat being adapted to be operatively seated in said circular valve-connecting opening of said manifold, said pliable valve sleeve having an outer diameter in conformity with the inner wall of said valve-connecting opening of said cross-type manifold, said pliable valve sleeve having a shoulder as extension of its peripheral surface, and said pliable valve sleeve having a valve cover with an outer diameter just equal to that of said valve-connecting opening of said cross-type manifold and with a connection hole at the center of said valve cover, and a hole in said shoulder for communication with said tubular water pressure pipe of said tie ring;

    (d) a valve extender adapted to be seated at least in said pliable valve sleeve, said valve extender having a conical head, a neck with an outer diameter in conformity with that of the connecting hole in said shoulder of said pliable valve sleeve, a cylindrical portion, a disc-shaped recess in its bottom, and a tubular water pressure balance duct extending along its center;

    (e) an annular connection cover adapted to be seated in said valve-connecting opening of said cross-type manifold, said annular connection cover having a stop hole for communication with said tubular water pressure pipe of said circular tie ring;

    (f) a metal extending pin with magnetic properties;

    (g) a pliable cylindrical stop head operatively connected at one end of said metal extending pin;

    (h) an extending pin container comprising a dish-shaped portion and a tubular extension, for containing said extending pin;

    (i) a compression spring, operatively mounted in said tubular extension of said extending pin container;

    (j) an induction coil for mounting in it said extending pin container and said compression spring in said induction coil, said induction coil being adapted to be operatively connected to said cross-type manifold;

    (k) a cylindrical valve control post which is adapted to operatively disposed in and which corresponds in diameter to said tubular transverse portion of said cross-type manifold, said cylindrical valve control post having two leak-proof rings mounted at its central portion, said cylindrical valve control post having at its front end a pin adapted to be aligned with the center of said valve aperture in said tubular transverse portion of said cross-type manifold, and said cylindrical valve control post having a cylindrical selector element corresponding in size to said first selector slot in said tubular transverse portion of said cross-type manifold;

    (l) a valve control ring having a first groove at its inner wall for cooperating with said cylindrical selector element of said cylindrical valve control post;

    (m) a cylindrical water temperature control post adapted to be operatively mounted in and having a diameter in conformity with said water temperature control section in said cross-type manifold, said control post having a hollow rear tubular section, a water outlet at said rear end, and a water inlet in the central portion of said hollow rear tubular section at a position in conformity with the cool water pipe, said cylindrical water temperature control post having two leak-proof rings mounted at its central portion, and said cylindrical water temperature control post having beneath its forward end a cylindrical selector duct corresponding in size to said second selector slot of said water temperature control section of said cross-type manifold;

    (n) a ring with a projecting block at its inner circumference corresponding to said first selector slot for cooperating therewith;

    (o) a temperature control ring having an oblique groove in its inner wall for cooperating with and corresponding in size to said second walled slot of said water temperature control section of said cross-type manifold, and said temperature control ring also having a plurality of openings along its inner wall;

    (p) a circular temperature setting disc adapted to be connected at said temperature control ring and having a mounting block, at least one rectangular opening, and a pin hole in said block above said opening, and said temperature setting disc having a central round hole, and two screw holes below said central hole;

    (q) a temperature setting pin adapted to be mounted in and corresponding in diameter to said pin hole in said block of said temperature setting disc;

    (r) a compression spring for said circular temperature setting disc and adapted to be positioned beneath said block of said circular temperature setting disc;

    (s) a disc-shaped cover having four equidistant retainer blocks arranged about at one side about its center;

    wherein said valve extender neck is inserted in said pliable valve sleeve, and clamped by said circular tie ring at one side and said annular connection cover at the other side, with said water pressure pipe of said circular tie ring passing through said hole in said shoulder of said pliable valve sleeve and said stop hole of said annular connection cover, and said valve extender neck is fixed in said stop hole of said annular connection cover;

    wherein said selector element of said cylindrical valve control post is located within said first groove in said valve control ring, with said valve control post and said valve control ring being connected to said cross-type manifold in such a way that said cylindrical selector element is cooperatingly mounted in said first selector slot, and said pin of said valve control post is positioned at the center of said valve aperture of said transverse portion of said cross-type manifold;

    wherein said cylindrical selector duct of said cylindrical water temperature control post is located within said oblique groove of said temperature control ring in such a way that said cylindrical selector duct is operatively disposed in said second selector slot of said water temperature control section of said cross-type manifold, for regulating outgoing water temperature by selectively matching said water inlet of said cylindrical water temperature control post with the cool and hot water pipes, and permitting flowing of cool and hot water alone;

    wherein said valve control ring cooperatingly engages said water temperature control post, and said valve control ring is operatively connected on said cross-type manifold;

    wherein the valve composed of said valve extender, said pliable valve sleeve, said annular connection cover, and said circular tie ring, is operatively connected to the valve-connecting opening of said cross-type manifold; and
