Abstract:
A core shaft of the control stick of a vertical type faucet, comprising a faucet body, a locking ring unit, a valve case, a valve, a core shaft of the control stick, a stick fixing mount, a support base, a switch mount, and a faucet handle wherein said faucet body has a receiving cavity with an internally threaded locking upper section disposed at the rear center thereof to be communicated with internal water inlet and outlet passages thereof, and said locking ring unit has a locking hole disposed at the center thereof and externally threaded locking section disposed at the lower outer periphery thereof; said present invention characterized by that,said valve case, stepwise, having a valve chamber disposed at the inner side thereof and two limiting blocks disposed at the top of said valve chamber thereof; said valve having a large and a small stepwise cavities disposed at the inner side thereof with a pair of opposite semi-circular abutting flanges disposed at the bottom edge of said small stepwise cavity thereof, an eccentric through hole disposed at the top side thereof, and a positioning block extending outwards at the bottom of the outer periphery thereof; said core shaft of the control stick being made up of an arc actuation block disposed at the bottom thereof, a bulged lower section extending at the top of said arc actuation block thereof with a post projecting at both ends out of the middle bulged section thereof, a main shaft body extending for a proper length at top of said bulged lower section thereof, and an externally threaded upper section disposed at the top thereof; said stick fixing mount having a through hole disposed at the center thereof, a symmetric tapered facet with a bulged middle section defining the outer periphery thereof, a slant abutment facet disposed at the upper inner periphery of said through hole thereof, and a pair of corresponding slots and two symmetric positioning blocks disposed respectively at the bulged middle section of said symmetric tapered facet thereof; said support base having a receiving groove disposed at the top thereof, a stop ring disposed at the lower end thereof, an arc recess defining one edge of said stop ring thereof and a pair of symmetric semi-circular cuts defining the upper edge of said receiving groove thereof; said switch mount being made up of an upper switch valve and a lower switch valve wherein said upper switch valve, having a link activation cavity disposed at the top thereof, can be horizontally moved and rotated on said lower switch valve thereof for regulating the discharge and temperature of cold and hot water; said faucet handle, vertical in type, has a coupling end disposed at the bottom thereof and a turning part extending at the upper section thereof; in assembly, said core shaft of the control stick joined to said stick fixing mount is adapted to the large stepwise cavity of said valve thereof with the upper part of said joined core shaft thereof and stick fixing mount received at said small stepwise cavity thereof, and said support base is led and joined to said large stepwise cavity from the bottom thereof; said valve thereof is then located onto said switch mount with the arc actuation block of said core shaft thereof inserted into the link activation cavity of said switch mount thereof; said valve case is adapted to encase said valve and said switch mount therein to complete a switch valve unit which is then adapted to the receiving cavity of said faucet body thereof and screw joined thereto via said locking ring unit thereof; said main shaft body thereof extending out of said valve thereof is screw joined to said faucet handle via said externally threaded upper section thereof to complete the assembly; whereby, in operation, the turning part of said faucet handle is pushed forwards or downwards, bending said core shaft of the control stick along with said arc actuation block which will activate said link activation cavity and said upper switch valve to move backwards for cold and hot water to be channeled via said lower switch valve for the discharge thereof for use; or, to adjust the water temperature, said faucet handle thereof is first bent forwards and then switched to the right or left to activate said upper switch valve therewith via said arc actuation block so as to adjust the amount of cold or hot water channeled via said lower switch valve thereof for use.
