Abstract:
1. A ceramic plate for stick operated cure shaft of a faucet, comprising a faucet body, a locking unit, a valve case, a mount seat, a control stick, a stick fixing mount, a fixing unit, an upper switch valve, a lower switch valve, 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 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 mount seat having a large and a small stepwise cavities disposed at the inner side thereof with a pair of opposite semi-circular abutting grooves 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 control stick being made up of an arc actuating block having a flat facet disposed at the bottom thereof, a bulged lower section extending at the top of said arc actuating 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 fixing unit 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 semicircular cuts defining the upper edge of said receiving groove thereof; said upper switch valve having a linkage groove disposed at the top thereof, and a curved switching groove with a certain width disposed at the bottom thereof; said lower switch valve having a hot water inlet holes, a cold water inlet hole and a water outlet hole disposed thereon, and being mounted onto a base having cold/hot water through holes disposed thereon; in assembly, said control stick joined to said stick fixing mount is adapted to the large stepwise cavity of said mount seat thereof with the upper part of the control stick and stick fixing mount received at said small stepwise cavity thereof, and said fixing unit is led and joined to said large stepwise cavity from the bottom thereof; said mount seat thereof is then located onto the upper switch valve with the arc actuating block of said control stick inserted into the linkage groove of said upper switch valve; said valve case is adapted to encase said mount seat and said upper and lower switch valves 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 unit thereof; said main shaft body thereof extending out of said mount seat is screw joined to said faucet handle via said externally threaded upper section thereof to complete the assembly thereof; whereby, for the discharge of cold water, said faucet handle is switched to the right to activate said control stick which will slide said upper switch valve to the left for a certain angle via said actuating block thereof; said upper switch valve will keep sliding to the left till said curved switch groove thereof covers on top of both the cold water inlet hole and water outlet hole of the lower switch valve for cold water coming out through the cold water through hole of said base and the cold water inlet hole of said lower switch valve to go out at said water outlet hole thereof and discharge out of said faucet body for use; for the discharge of hot water, said faucet handle is switched to the left to activate said control stick which will slide said upper switch valve to the right for a certain angle via said actuating block thereof till said curved switch groove covers on top of both the hot water inlet hole and water outlet hole of the lower switch valve for hot water coming through the hot water through hole of said base and the hot water inlet hole of said lower switch valve to go out at said water outlet hole thereof and discharge out of said faucet body for use, which, without contradicting to the habitual manner of using a cold/hot water faucet, can safely prevent users from carelessly burning themselves by hot water.
