Abstract: The present invention provides a spool seat with a positioning structure, which resolves the shortcomings of the assembly of a typical spool ceramic disc and spool seat. The spool seat of the present invention is provided with a chamber space for locating the fixed ceramic disc. The chamber space is provided with an internal locating portion which comprises an internal locating flange and external locating flange. An external locating portion is protruded from the chamber space. The chamber space is divided into inlet space and outlet space via the arrangement of internal locating portion. It is possible to eliminate the space restrictions for the fixed ceramic disc, and also prevent the rotation and slide or displacement when the fixed ceramic disc is assembled into the chamber space of the spool seat.

Abstract: The present invention provides a water control valve with snapping action. The valve shell of the water control valve includes a main body and combined base. A snapping assembly is arranged between the main body and combined base, being in snap-fit engagement, so that the inner space of the valve shell expands to accommodate more switching valve assemblies for better applicability. When the main body is coupled with the combined base, the overlapped portion of the main body and combined base can be reduced by configuration of the snapping assembly, thereby optimizing the utilization of the inner space. So, the switching valve assemblies of different dimensions and specifications are suitable for a wider range of applications.

Abstract: The present invention provides a spool of a faucet with a two-sided effluent structure to improve the shortcomings of a faucet spool with the known cold/hot water switching structure. The spool includes a spool assembly mounted into the valve shell. A valve base is placed at bottom of the valve shell and is provided with a cold water inlet, hot water inlet and two water outlets. The cold and hot water inlets are arranged centrally onto the bottom of the valve base, while two water outlets are assembled separately but symmetrically at both ends of cold and hot water inlets. When the spool is arranged separately onto the wall, the configuration of cold and hot water inlet pipes are greatly simplified to reduce the configuration cost of pipelines with improved applicability.

Abstract: The present invention provides a lateral draft tube for a water control valve core, which is defined by a through-type groove and upper and lower openings. The through-type groove is sleeved around the shell of the water control valve core. The upper and lower portions have different diameters on the external wall of the draft tube. A ring flange is formed on the upper portion, and a guide ring surface is formed on the lower portion. The ring flange is provided with a sealing ring, and a drainage portion is arranged at the lower end of the draft tube to connect the through-type groove and guide ring surface. The draft tube can be located higher than the water control valve core, such that upward flow of the guide ring surface is not limited by the water control valve core. Thus, the upward flow of the water control valve core improves.

Abstract: A ceramic plate for stick operated core shaft of a faucet is mainly made up of 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 the control stick activated by the faucet handle is engaged with the upper switch valve via an actuating block of the control stick inserted to a linkage groove disposed at the top of the upper switch valve for regulating the discharge of cold/hot water. When the faucet handle is switched to the right, the control stick will move the upper switch valve to slide to the left till a curved switch groove of the upper switch valve covers on top of a cold water inlet hole of the lower switch valve for the discharge of cold water out of a water outlet hole of the lower switch valve.
