Abstract:
A liquid flow control tap, comprising:a tap body having both a liquid outlet port and a lower opening and defining a liquid passage therein;a hand lever movably engaging with said tap body in order to selectively open the outlet port, said hand lever including:a handle and;a hook block provided at one end of said handle and received into said lower opening of the tap body, said hook block being movably caught by a stop shoulder of the tap body and;a valve operating end provided at the other end of the handle being interiorly seated on the outlet port of the tap body;an outer-threaded member brought into engagement with the outlet port, thus holding the valve operating end of the lever in the outlet port of the tap body;a spring-biased valve movably seated on an annular step provided in the liquid passage of the tap body, with a valve stem of the valve extending toward the outlet port and being seated on said valve operating end of the lever, said valve being selectively opened by the lever so as to discharge liquid from the outlet port;a hollow cylindrical magnet arranged in the liquid passage of the tap body, with one end of the magnet being seated on said valve at a position opposite to the valve stem, said magnet being adapted for magnetizing the liquid prior to discharging the liquid from the outlet port;a liquid junction member movably positioned on a hot and cold liquid inlet part of the liquid passage of the tap body, said junction member being adapted for mixing cold liquid with hot liquid into a mixed liquid while controlling the temperature of the mixed liquid;a rotating shaft engaging with both said liquid junction member at the interior of the tap body and a rotatable handle at the exterior of the tap body, thus selectively rotating the junction member relative to the hot and cold liquid inlet part in accordance with a rotating motion of the rotatable handle while controlling the temperature of the mixed liquid;a buoyancy-operable lever having a pushing part at one end thereof and interiorly hinged to said tap body by a pin in said opening of the tap body, said buoyancy-operable lever being adapted for selectively pushing the hook block of the hand lever so as to close the outlet port of the tap body;a vertical push rod connected to both the other end of said buoyancy-operable lever at its upper end and a floating member at its lower end; anda liquid tank receiving said floating member therein and connected to a liquid bowl containing liquid discharged from the outlet port of the tap body, thus allowing the push rod with the floating member to selectively operate the buoyancy-operable lever in accordance with a liquid level in said liquid bowl.
