## Background
FIELD OF THE INVENTION
The present invention relates to a control valve in a water channel, and more particularly to a control valve in a water channel that can control the amount of water and the open/close operation of two different water sources.
BACKGROUND OF THE INVENTION
A conventional control valve for a faucet is used to control the open/close operation or the amount of water flow by rotating or moving up the handle of the faucet.
However, the conventional control valve is disadvantageous because: (i) one control valve can only be used for one kind of flow (such as cold water or tap water). In other words, when a faucet has to provide two different kinds of flows (such as cold water and hot water, or tap water and purified water), there is a need to install another control valve in the faucet. As a result, it increases the complexity of the structure of faucet; and (ii) it is inconvenient for a user to operate two control valves in the same time. Therefore, there remains a need for a new and improved design for a control valve for water channel to overcome the problems presented above.
SUMMARY OF THE INVENTION
The present invention provides a control valve for water channel, which comprises of, from top to bottom, a control shaft bolt, a sliding valve disc, a fixing valve disc and a valve base. A valve shell combining with the valve base covers around a lower portion of the control shaft bolt, the sliding valve disc and the fixing valve disc to prevent mentioned components from falling out. The valve shell has a compartment, and an opening is formed at a top portion of the valve shell. The control shaft bolt is secured in the compartment of the valve shell, and an upper portion of the control shaft bolt penetrates through the opening to stick out from the valve shell. An arc edge vertically protrudes from an inner wall of the valve shell, and two locating slots are formed at relative positions on the arc edge with proper angle. An interval is formed between two ends of the arc edge to receive a rotating channel, and the position of the rotating channel is limited by the arc edge. By connecting the control shaft bolt to a shaft base, the shaft base can be driven to rotate with control shaft bolt simultaneously. Two locating pieces are formed at an outer periphery of the shaft base, and a driving block having an arc edge protrudes from an upper portion of the outer periphery of the shaft base. Two blocking edges are formed at two lateral sides of the driving blocking to achieve blocking effect, and a plurality of driving pins protrudes from a bottom of the shaft base. The bottom of the sliding valve disc has two recessed portions which are a first water sink and a second water sink, and the first water sink and the second water sink are separated with an angle. A plurality of driving grooves is formed at a top of the sliding valve disc, and when the sliding valve disc connects to a top of the fixing valve disc in the compartment, the driving pins are engaged with the driving grooves. The fixing valve disc is penetrated to form a first water inlet and a first water outlet on one side, and to form a second water inlet and a second water outlet on the other side. Also, the first water inlet and the second water inlet are aligned with the first water outlet and the second water outlet. A periphery edge of the fixing valve disc comprises of engaging slots to connect the fixing valve disc with the valve base. The valve base has a first inlet hole, a first outlet hole, a second inlet hole and a second outlet hole, which are at corresponding positions of the first water inlet, the first water outlet, the second water inlet and the second water outlet. A connecting piece are formed at a lateral periphery of the valve base to upwardly engage with the valve shell, and engaging blocks protrude from a surface of the valve base to engage with the engaging slots. As a result, the fixing valve disc can be loaded and secured on the top of the valve base.
Comparing with conventional control valve for water channel, the present invention is advantageous because: (i) the amount and the open/close operation of the two different kinds of water sources can be operated and controlled by a single control valve of the water channel to simplify the complexity in structure; and (ii) it is convenient for a user to control the amount and the open/close operation of two different kinds of water sources by a single control valve.

In order to further understand the goal, characteristics and effect of the present invention, a number of embodiments along with the drawings are illustrated as following:
Referring to FIGS. 1 to 6, the present invention provides a control valve for water channel, which comprises of, from top to bottom, a control shaft bolt (20), a sliding valve disc (30), a fixing valve disc (40) and a valve base (50). A valve shell (10) combining with the valve base (50) covers around a lower portion of the control shaft bolt (20), the sliding valve disc (30) and the fixing valve disc (40) to prevent mentioned components from falling out. The valve shell (10) has a compartment (11), and an opening (12) is formed at a top portion of the valve shell (10). The control shaft bolt (20) is secured in the compartment (11) of the valve shell (10), and an upper portion of the control shaft bolt (20) penetrates through the opening (12) to stick out from the valve shell (10). An arc edge (13) vertically protrudes from an inner wall of the valve shell (10), and two locating slots (14) are formed at relative positions on the arc edge (13) with proper angle. An interval is formed between two ends of the arc edge (13) to receive a rotating channel (15), and the position of the rotating channel (15) is limited by the arc edge (13). By connecting the control shaft bolt (20) to a shaft base (21), the shaft base (21) can be driven to rotate with control shaft bolt (20) simultaneously. Two locating pieces (211) are formed at an outer periphery of the shaft base (21), and a driving block (212) having an arc edge protrudes from an upper portion of the outer periphery of the shaft base (21). Two blocking edges (213) are formed at two lateral sides of the driving blocking (212) to achieve blocking effect, and a plurality of driving pins (214) protrudes from a bottom of the shaft base (21). The bottom of the sliding valve disc (30) has two recessed portions which are a first water sink (31) and a second water sink (32), and the first water sink (31) and the second water sink (32) are separated with an angle. A plurality of driving grooves (33) is formed at a top of the sliding valve disc (30), and when the sliding valve disc (30) connects to a top of the fixing valve disc (40) in the compartment (11), the driving pins (214) are engaged with the driving grooves (33). The fixing valve disc (40) is penetrated to form a first water inlet (41) and a first water outlet (42) on one side, and to form a second water inlet (43) and a second water outlet (44) on the other side. Also, the first water inlet (41) and the second water inlet (43) are aligned with the first water outlet (42) and the second water outlet (44). A periphery edge of the fixing valve disc (40) comprises of engaging slots (45) to connect the fixing valve disc (40) with the valve base (50). The valve base (50) has a first inlet hole (51), a first outlet hole (52), a second inlet hole (53) and a second outlet hole (54), which are at corresponding positions of the first water inlet (41), the first water outlet (42), the second water inlet (43) and the second water outlet (44). A connecting piece (44) are formed at a lateral periphery of the valve base (50) to upwardly engage with the valve shell (10), and engaging blocks (56) protrude from a surface of the valve base (50) to engage with the engaging slots (45). As a result, the fixing valve disc (40) can be loaded and secured on the top of the valve base (50).
In one embodiment, an O-ring (22) is affixed to an outer periphery of the shaft base (21) of the control shaft bolt (20).
In another embodiment, gaskets (57) are affixed to positions on the top and the bottom of the valve base (50), corresponding to the first inlet hole (51), the first outlet hole (52), the second inlet hole (53) and the second outlet hole (54).
In actual application, a first kind of water source such as cold water or tap water is conducted by the first water inlet (41) through the first inlet hole (51) into the control valve, and a second kind of water source such as hot water or purified water is conducted by the second water inlet (43) through the second inlet hole (53) into the control valve. As a result, the amount and the open/close operation of the two different kinds of water sources can be operated and controlled by a single control valve of the water channel. Before the control shaft bolt (20) is rotated, the two locating pieces (211) are engaged with the locating slots (14) of the valve shell (10) to keep the driving block (212) align with a center portion of rotating channel (15) (as shown in FIG. 4). Also, the maximum rotation angle of the control shaft bolt (20) is limited while the blocking edge (213) bears against the arc edge (13). The control valve can be closed by misaligning the first water sink (31) and the second water sink (32) with the first water inlet (41) and the second water inlet (43), leading to the first water inlet (41) and the second water inlet (43) blocked by the sliding valve disc (30) (as shown in FIGS. 5 and 6). When the first kind of water source is needed, a user can rotate the control shaft bolt (20) in one direction to drive the sliding valve disc (30). Referring to FIGS. 7 to 9, by aligning the first water sink (31) with the first water inlet (41) and the first water outlet (42), the first water source from the first inlet hole (51) can flow through the first water inlet (41), first water sink (31) and first water outlet (42), and flow out of the control valve from the first outlet hole (52). Further, the control valve can be closed by rotating the control shaft bolt (20) back to initial position. On the other hand, referring to FIG. 10, when the faucet has to provide the second kind of water source, a user can rotate the control shaft bolt (20) in the other direction to align the second water sink (32) with the second water inlet (43) and the second water outlet (44), leading to providing the second kind of water source.
Comparing with conventional control valve for water channel, the present invention is advantageous because: (i) the amount and the open/close operation of the two different kinds of water sources can be operated and controlled by a single control valve of the water channel to simplify the complexity in structure; and (ii) it is convenient for a user to control the amount and the open/close operation of two different kinds of water sources by a single control valve.
Having described the invention by the description and illustrations above, it should be understood that these are exemplary of the invention and are not to be considered as limiting. Accordingly, the invention is not to be considered as limited by the foregoing description, but includes any equivalents.
