[0045] See also Figures 1 to 12 , a waterway control component in an embodiment of the present invention includes:
[0046] The housing 100 is provided with a water inlet and a water outlet;
[0047] A rotating handle 200 with a portion located inside the housing 100 and another portion extending outside the housing 100; a first ceramic plate 300 located inside the housing 100, with a plurality of communication ports provided on the first ceramic plate 300, the communication ports being connected to corresponding water outlets or water inlets; and
[0048] The second ceramic tile 400 cooperates with the first ceramic tile 300, and the second ceramic tile 400 is connected to the rotating handle 200. The second ceramic tile 400 is provided with a plurality of switching ports that can be connected with the corresponding water inlets. When the rotating handle 200 rotates, the second ceramic tile 400 is driven to rotate, and the corresponding switching port is switched to be connected with the corresponding connecting port.
[0049] In the waterway control assembly of the present invention, the waterway switching between the corresponding water inlet and water outlet is realized by providing the first ceramic tile 300 and the second ceramic tile 400. Compared with the structure of implanting the valve core assembly in the prior art, it is more reliable.
[0050] It should be noted that the housing 100 in the embodiment of the present invention supports all supporting layer structures located in the internal structure of the housing 100; the waterway switching between the water inlet and the water outlet can be achieved by rotating the handle 200. The water inlet and the water outlet can be one-to-many, many-to-one, or many-to-many. Among them, one-to-many can be understood as one water inlet corresponding to multiple water outlets, and by rotating the rotating handle 200, the second ceramic piece 400 is driven to rotate, so as to achieve water discharge from different water outlets; many-to-one can be understood as multiple water inlets corresponding to one water outlet, and by rotating the rotating handle 200, the second ceramic piece 400 is driven to rotate, so as to achieve water inlet from different water inlets; many-to-many can be understood as multiple water inlets corresponding to multiple water outlets, and by rotating the rotating handle 200, the second ceramic piece 400 is driven to rotate, so as to achieve the conduction between the water inlet and the corresponding water outlet, so that the waterway is conducted according to the predetermined requirements.
[0051] In the embodiment of the present invention, the water inlet includes a first water inlet 101 - 1 , and the first water inlet 101 - 1 is connected to the internal cavity of the housing 100 ;
[0052] The water outlet includes a first water outlet 102-1;
[0053] The communication port includes a first communication port 301, a second communication port 302 and a connection channel 303, wherein the connection channel 303 connects the first communication port 301 with the second communication port 302, and the connection channel 303 is connected with the first water outlet 102-1;
[0054] The switching port includes a first switching port 401. When located at the first position, the first switching port 401 is not conductive with the first connecting port 301 and the second connecting port 302; when located at the second position, the first switching port 401 is conductive with the first connecting port 301, and the first switching port 401 is not conductive with the second connecting port 302; when located at the third position, the first switching port 401 is not conductive with the first connecting port 301, and the first switching port 401 is conductive with the second connecting port 302.
[0055] It can be seen that in the embodiment of the present invention, there is a first water inlet 101-1 and a first water outlet 102-1. When the rotating handle 200 is turned to drive the second ceramic piece 400 to rotate to the first position, the first switching port 401 and the first connecting port 301 and the second connecting port 302 are all non-conductive. At this time, the water in the first water inlet 101-1 cannot flow out from the water outlet through the first ceramic piece 300 and the second ceramic piece 400.
[0056] When the rotating handle 200 is turned to drive the second ceramic piece 400 to rotate to the second position, the first switching port 401 is connected to the first connecting port 301, and the first switching port 401 is not connected to the second connecting port 302. At this time, the water in the first water inlet 101-1 enters the first connecting port 301 through the first switching port 401. Since the connecting channel 303 connects the first connecting port 301 and the first water outlet 102-1, the water will enter the first water outlet 102-1 through the connecting channel 303 and flow out.
[0057] When the rotating handle 200 is turned to drive the second ceramic piece 400 to rotate to the third position, the first switching port 401 is connected to the second connecting port 302, and the first switching port 401 is not connected to the first connecting port 301. At this time, the water in the first water inlet 101-1 enters the second connecting port 302 through the first switching port 401. Since the connecting channel 303 connects the second connecting port 302 and the first water outlet 102-1, the water will enter the first water outlet 102-1 through the connecting channel 303 and flow out.
[0058] The number of the first water inlets 101 - 1 is one or more, and the first water inlets 101 - 1 can be connected to the corresponding first water inlets 101 - 1.
[0059] In order to further optimize the above solution, in the embodiment of the present invention, the water inlet further includes a second water inlet 101-2;
[0060] The water outlet includes a second water outlet 102-2;
[0061] The communication port includes a third communication port 304 and a fourth communication port 305; wherein the third communication port 304 is communicated with the second water inlet 101-2, and the fourth communication port 305 is communicated with the second water outlet 102-2;
[0062] The switch port further includes a second switch port 402 . When located at the first position and the second position, the second switch port 402 is not connected to the third communication port 304 and the fourth communication port 305 . When located at the third position, the second switch port 402 is connected to both the third communication port 304 and the fourth communication port 305 .
[0063] In combination with the above scheme, when the rotating handle 200 is rotated to drive the second ceramic piece 400 to rotate to the first position, the first switching port 401 is not conductive with the first connecting port 301 and the second connecting port 302, and at the same time, the second switching port 402 is not conductive with the third connecting port 304 and the fourth connecting port 305; at this time, the water in the first water inlet 101-1 and the water in the second water inlet 101-2 cannot flow out from the corresponding water outlets through the first ceramic piece 300 and the second ceramic piece 400.
[0064] When the rotating handle 200 is turned to drive the second ceramic plate 400 to rotate to the second position, the first switching port 401 is connected to the first connecting port 301, and the first switching port 401 is not connected to the second connecting port 302. At this time, the water in the first water inlet 101-1 enters the first connecting port 301 through the first switching port 401. Since the connecting channel 303 connects the first connecting port 301 and the first water outlet 102-1, the water will enter the first water outlet 102-1 through the connecting channel 303 and flow out; at the same time, the second switching port 402 is not connected to the third connecting port 304 and the fourth connecting port 305, and the water in the second water inlet 101-2 cannot flow out from the second water outlet 102-2 through the first ceramic plate 300 and the second ceramic plate 400.
[0065] When the rotating handle 200 is turned to drive the second ceramic plate 400 to rotate to the third position, the first switching port 401 is connected to the second connecting port 302, and the first switching port 401 is not connected to the first connecting port 301. At this time, the water in the first water inlet 101-1 enters the second connecting port 302 through the first switching port 401. Since the connecting channel 303 connects the second connecting port 302 and the first water outlet 102-1, the water will enter the first water outlet 102-1 through the connecting channel 303 and flow out; at the same time, the second switching port 402 is connected to the third connecting port 304 and the fourth connecting port 305, and the water in the second water inlet 101-2 enters the fourth connecting port 305 from the third connecting port 304 through the second switching port 402. Since the fourth connecting port 305 is connected to the second water outlet 102-2, the water in the second water inlet 101-2 flows out through the second water outlet 102-2.
[0066] In order to further optimize the above solution and further realize linkage, in an embodiment of the present invention,
[0067] The water inlet also includes a third water inlet 101-3;
[0068] The communication port includes a fifth communication port 306; wherein the fifth communication port 306 is communicated with the third water inlet 101-3;
[0069] The switch port further includes a second switch port 402 . When located at the first position and the third position, the second switch port 402 is not connected to the fifth communication port 306 and the fourth communication port 305 . When located at the second position, the second switch port 402 is connected to both the fifth communication port 306 and the fourth communication port 305 .
[0070] In conjunction with the above solutions, please refer to Figure 7 and Figure 8When the rotating handle 200 is rotated to drive the second ceramic piece 400 to rotate to the first position, the first switching port 401 is not conductive with the first connecting port 301 and the second connecting port 302, the second switching port 402 is not conductive with the third connecting port 304 and the fourth connecting port 305, and the second switching port 402 is not conductive with the fifth connecting port 306 and the fourth connecting port 305; at this time, the water in the first water inlet 101-1 and the water in the second water inlet 101-2 cannot flow out from the corresponding water outlets through the first ceramic piece 300 and the second ceramic piece 400.
[0071] See also Fig. 9 and Fig.10 When the rotary handle 200 is turned to drive the second ceramic piece 400 to rotate to the second position, the first switching port 401 is connected to the first connecting port 301, and the first switching port 401 is disconnected from the second connecting port 302. At this time, the water in the first water inlet 101-1 enters the first connecting port 301 through the first switching port 401. Since the connecting channel 303 connects the first connecting port 301 and the first water outlet 102-1, the water will enter the first water outlet 102-1 through the connecting channel 303 and flow out. out; the second switching port 402 is not connected with the third connecting port 304 and the fourth connecting port 305, and the water in the second water inlet 101-2 cannot flow out from the second water outlet 102-2 through the first tile 300 and the second tile 400; the second switching port 402 is connected with the fifth connecting port 306 and the fourth connecting port 305, and the water in the third water inlet 101-3 enters the fifth connecting port 306 and then enters the fourth connecting port 305 through the second switching port 402, and flows out from the fourth connecting port 305.
[0072] See also Fig.11 and Fig.12 , when the rotary handle 200 is turned to drive the second ceramic piece 400 to rotate to the third position, the first switching port 401 is connected to the second connecting port 302, and the first switching port 401 is not connected to the first connecting port 301. At this time, the water in the first water inlet 101-1 enters the second connecting port 302 through the first switching port 401. Since the connecting channel 303 connects the second connecting port 302 and the first water outlet 102-1, the water enters the first water outlet 102-1 through the connecting channel 303 and flows out. At the same time, the second switching port 4 02 is connected with the third connecting port 304 and the fourth connecting port 305, and the water in the second water inlet 101-2 enters the fourth connecting port 305 from the third connecting port 304 through the second switching port 402. Since the fourth connecting port 305 is connected with the second water outlet 102-2, the water in the second water inlet 101-2 flows out through the second water outlet 102-2; the second switching port 402 is not connected with the fifth connecting port 306 and the fourth connecting port 305, and the water in the third water inlet 101-3 cannot flow out from the fourth connecting port 305.
[0073] In order to facilitate the external water circuit, the second water inlet 101-2 is detachably provided with a first water inlet pipe 600, and the water inlet channel in the first water inlet pipe 600 is communicated with the second water inlet 101-2; the third water inlet 101-3 is detachably provided with a second water inlet pipe 700, and the water inlet channel in the second water inlet pipe 700 is communicated with the third water inlet 101-3. By providing the first water inlet pipe 600 and the second water inlet pipe 700, it is more convenient to arrange the water pipes on the water circuit control assembly. The first water inlet pipe 600 and the second water inlet pipe 700 can also be provided with joints to more quickly arrange the water connection. In addition, in order to adapt to different application scenarios, a first plug 601 is provided at the other end of the first water inlet pipe 600. When water needs to flow out from the other end, the first plug 601 can be removed; a second plug 701 is provided at the other end of the second water inlet pipe 700. When water needs to flow out from the other end, the second plug 701 can be removed.
[0074] From the above content, it can be seen that the present solution has three water inlets and two water outlets. By setting corresponding ports on the first ceramic tile 300 and the second ceramic tile 400, corresponding water path switching can be achieved. Moreover, the present invention only sets switching ports and connecting ports, which is simple in structure and more reliable in coordination compared with the valve core assembly in the prior art.
