The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] like Figures 1 to 8 As shown, some embodiments of this application provide a water distribution valve with a first direction Z, which is mainly used to improve the assembly efficiency and ease of assembly between the seal 600 and the fastener 500, and to improve the sealing quality and stability of the seal 600 between the fastener 500 and the housing.

[0026] The water distribution valve includes a housing 100, a shaft 200, a moving plate 300, a stationary plate 400, a fastener 500, and a seal 600.

[0027] The outer shell 100 defines a receiving cavity 110 with a liquid inlet 120 along the first direction Z. The side wall of the outer shell 100 is provided with at least one drain outlet 130 communicating with the receiving cavity 110. In this embodiment, the number of drain outlets 130 can be one, two or more, and can be specifically set according to the actual situation.

[0028] It is understood that the inlet 120 is connected to the outlet 130 through the receiving cavity 110, that is, external liquid can enter the receiving cavity 110 through the inlet 120 and be discharged from the outlet 130.

[0029] The outer shell 100 has a first wall surface 140 facing the receiving cavity 110. It should be noted that the first wall surface 140 is located between the liquid inlet 120 and the liquid outlet 130, that is, the first wall surface 140 is the inner wall of the receiving cavity 110.

[0030] Additionally, the shaft 200 passes through the outer casing 100 along the first direction Z, and is rotatably connected to the outer casing 100. It should be noted that the end of the shaft 200 facing away from the liquid inlet 120 along the first direction Z is located outside the receiving cavity 110; that is, the end of the shaft 200 facing away from the liquid inlet 120 along the first direction Z extends to the outside of the casing, while the end of the shaft 200 close to the liquid inlet 120 along the first direction Z is located in the receiving cavity 110 and is rotatably connected to the casing about the axis of the shaft 200.

[0031] In this embodiment, the movable piece 300 is housed in the receiving cavity 110, and the movable piece 300 is connected to one end of the shaft 200 near the liquid inlet 120, that is, the shaft 200 can drive the movable piece 300 to rotate synchronously during the rotation of the housing.

[0032] The stationary plate 400 is disposed on the side of the moving plate 300 away from the shaft 200, and the stationary plate 400 is rotatably connected to the moving plate 300, with the side of the stationary plate 400 facing the moving plate 300 in contact with the side of the moving plate 300 facing the stationary plate 400.

[0033] Fastener 500 is disposed on the side of the stationary piece 400 away from the moving piece 300 and connects the fastener 500 to the housing 100. Specifically, the fastener 500 is connected to the first wall surface 140. The connection method between the fastener 500 and the housing 100 includes any one of bonding, snap-fit, threaded connection, bolt connection, tenon and mortise connection or integral molding, which can be specifically set according to the actual situation.

[0034] The fastener 500 has a first connecting portion 510 on its side wall, and the sealing member 600 has a second connecting portion 610 at one end near the fastener 500. The second connecting portion 610 is connected to the first connecting portion 510, and the side of the second connecting portion 610 away from the first connecting portion 510 abuts against the first wall surface 140, thereby forming a sealed connection between the fastener 500 and the first wall surface 140 through the sealing member 600.

[0035] It should be noted that by connecting the first connecting part 510 and the second connecting part 610, the fastener 500 and the seal 600 are connected. Then, the connected fastener 500 and seal 600 are assembled into the receiving cavity 110, and the side of the second connecting part 610 away from the fastener 500 abuts against the first wall surface 140, thereby connecting the seal 600 to the first wall surface 140. The mutual abutment between the seal 600 and the first wall surface 140 not only ensures the stability of the connection between the seal 600 and the housing, enabling the water distribution valve provided in this application to withstand greater water pressure, but also improves the convenience of connection and assembly between the seal 600, the fastener 500, and the housing while ensuring the sealing quality of the seal 600 between the fastener 500 and the housing.

[0036] In some embodiments, one of the first connecting portion 510 and the second connecting portion 610 is a groove and the other is a protrusion. The protrusion is disposed in the groove and is connected to the inner wall of the groove to improve the stability and assembly efficiency of the connection between the first connecting portion 510 and the second connecting portion 610, thereby improving the stability, assembly efficiency and assembly convenience of the connection between the seal 600 and the fastener 500.

[0037] In some embodiments of this application, the first connecting portion 510 includes a plurality of mounting slots, and the second connecting portion 610 includes a plurality of protrusions. The number of mounting slots and protrusions can be any number of two or more values, and can be specifically set according to actual conditions. It should be noted that in this embodiment, the number of mounting slots and the number of protrusions are equal, and one protrusion corresponds to a connection with the wall of one mounting slot.

[0038] In this embodiment, the side of the protrusion facing the fastener 500 abuts against the inner wall of the mounting groove to seal the connection between the fastener 500 and the seal 600, and the side of the protrusion away from the fastener 500 abuts against the first wall surface 140 to form a sealed connection between the seal 600 and the housing.

[0039] like Figures 3 to 5 As shown, in some embodiments of this application, a plurality of mounting slots are spaced apart, and the plurality of mounting slots are arranged at equal intervals around the fastener 500, and the plurality of mounting slots are arranged in a ring around the fastener 500. In addition, a plurality of protrusions are spaced apart, and the plurality of protrusions are arranged at equal intervals around the fastener 500, and the plurality of protrusions are arranged in a ring around the fastener 500.

[0040] In some embodiments, the plurality of mounting slots are interconnected to form a first annular groove, and the plurality of protrusions are interconnected to form an annular protrusion. The annular protrusion is engaged in the first annular groove. It is understood that by connecting the annular protrusion to the first annular groove, the ease of connection between the fastener 500 and the seal 600 can be improved, and the sealing quality between the fastener 500 and the seal 600 can be further improved.

[0041] It should be noted that the annular protrusion in this embodiment is the second connecting part 610 in any of the above embodiments, and the first annular groove in this embodiment is the first connecting part 510 in any of the above embodiments.

[0042] like Figure 3 , Figure 5 and Figure 6 As shown, in some embodiments of this application, the fastener 500 has a limiting protrusion 520 on its periphery. The limiting protrusion 520 is annular, and the side of the limiting protrusion 520 facing the stationary piece 400 along the first direction Z is the sidewall of the mounting groove. The side of the limiting protrusion 520 facing the first wall surface 140 is spaced apart from the first wall surface 140 to form a clearance space, so that the second connecting part 610 of the seal 600 can be assembled into the clearance space and the side of the second connecting part 610 away from the fastener 500 abuts against the first wall surface 140, thereby sealing the clearance space.

[0043] In this embodiment, the inner wall of the sealing member 600 is provided with a limiting groove 620, which is an annular groove. The limiting protrusion 520 is connected to the groove wall of the limiting groove 620, thereby fixing the fastener 500 and the sealing member 600 together.

[0044] It is understandable that by connecting the first connecting part 510 and the second connecting part 610, and simultaneously connecting the limiting protrusion 520 and the limiting groove 620, a double sealing connection structure is formed, which further improves the stability of the connection between the sealing element 600 and the fastener 500, and also further improves the sealing quality between the sealing element 600 and the fastener 500, enabling the water divider valve to withstand greater water pressure and improving the stability of the water divider valve.

[0045] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the sealing element 600 is an elastic sealing element 600. That is, when the sealing element 600 abuts against the first wall surface 140, the sealing element 600 is squeezed by the first wall surface 140 and undergoes elastic deformation, so that the sealing element 600 has an elastic force on the first wall surface 140 along the first direction Z perpendicular to the first direction. This not only improves the stability of the connection between the sealing element 600 and the first wall surface 140, but also further improves the sealing quality between the sealing element 600 and the first wall surface 140, thereby improving the sealing quality between the sealing element 600 and the housing.

[0046] In addition, it is understandable that since the seal 600 is in a compressed state between the fastener 500 and the first wall surface 140, that is, in the direction perpendicular to the first direction Z, the side of the seal 600 away from the first wall surface 140 has an elastic force on the fastener 500, making the connection between the fastener 500 and the seal 600 tighter, thereby further improving the sealing quality between the fastener 500 and the seal 600.

[0047] Along the first direction Z, the outer diameter of the seal 600 gradually increases from the side closer to the fastener 500 to the side farther away from the fastener 500.

[0048] Furthermore, the outer diameter of the protrusion on the side closer to the stationary plate 400 along the first direction Z is equal to or greater than the inner diameter of the first wall surface 140, so that the side of the protrusion away from the stationary plate 400 along the first direction Z is pressed against the first wall surface 140 and undergoes elastic deformation, thereby improving the sealing quality and connection stability between the seal 600 and the first wall surface 140.

[0049] like Figure 5 and Figure 6As shown, in some embodiments of this application, the fastener 500 is provided with a first opening 530 through the first direction Z, and the seal 600 is provided with a second opening 630 along the first direction Z. The axis of the first opening 530 and the axis of the second opening 630 coincide, and the first opening 530 and the second opening 630 are in communication with each other.

[0050] The fastener 500 has a limiting ring 540 on the side facing away from the stationary piece 400 along the first direction Z. The limiting ring 540 abuts against the inner wall of the second opening 630 on the side facing the first wall surface 140. The limiting ring 540 and the first wall surface 140 limit the sealing member 600 along the direction perpendicular to the first direction Z, thereby further improving the stability of the connection between the sealing member 600 and the fastener 500, as well as the stability of the connection between the sealing member 600 and the housing 100, and improving the sealing quality between the sealing member 600, the fastener 500 and the housing 100.

[0051] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments of this application, the water distribution valve includes a first sealing ring 700, and the fastener 500 has a second annular groove 550 on the side facing the stationary plate 400. The first sealing ring 700 is disposed in the second annular groove 550. The first sealing ring 700 protrudes at least partially from the second annular groove 550 along the first direction Z and abuts against the side of the stationary plate 400 away from the moving plate 300, so as to form a sealed connection between the stationary plate 400 and the fastener 500, thereby improving the sealing quality between the fastener 500 and the stationary plate 400.

[0052] like Figure 2 As shown, in some embodiments of this application, the moving piece 300 has a first position and a second position relative to the stationary piece 400.

[0053] When the moving plate 300 is in the first position relative to the stationary plate 400, the liquid inlet 120 is connected to the liquid outlet 130 through the moving plate 300 and the stationary plate 400, so that external liquid can enter the receiving cavity 110 through the liquid inlet 120 and be discharged from the liquid outlet 130.

[0054] When the moving plate 300 is in the second position relative to the stationary plate 400, the moving plate 300 and the stationary plate 400 seal the liquid inlet 120. At this time, the moving plate 300 and the stationary plate 400 form a sealing barrier structure between the liquid inlet 120 and the liquid outlet 130 to prevent external liquid from entering the receiving cavity 110 through the liquid inlet 120.

[0055] like Figure 2 , Figure 7 and Figure 8 As shown, in some embodiments of this application, the stationary plate 400 has a first sealing part 410 and a first guide hole 420, the first guide hole 420 being connected to the liquid inlet 120, and the moving plate 300 has a second sealing part 310 and a second guide hole 320, the second guide hole 320 being connected to the liquid outlet 130.

[0056] In the first position, the first guide hole 420 is at least partially connected to the second guide hole 320. It is understood that during the rotation of the shaft relative to the housing 100, the moving plate 300 rotates synchronously. When the moving plate 300 is in the first position relative to the stationary plate 400, a portion of the first guide hole 420 is connected to the second guide hole 320, or the first guide hole 420 and the second guide hole 320 are completely connected, meaning the first guide hole 420 and the second guide hole 320 overlap. It is understood that the water inflow rate is adjusted by regulating the overlapping portion between the first guide hole 420 and the second guide hole 320.

[0057] In the second position, the first sealing part 410 covers the second guide hole 320 along the first direction Z, and the second sealing part 310 covers the first guide hole 420 along the first direction Z, thereby disconnecting the liquid inlet 120 and the liquid outlet 130 through the first sealing part 410 and the second sealing part 310 to prevent external liquid from entering the receiving cavity 110 through the liquid inlet 120.

[0058] like Figure 3 As shown, in some embodiments of this application, the sidewall of the outer shell 100 is provided with a plurality of drain ports 130, the plurality of drain ports 130 are spaced apart, and the plurality of drain ports 130 are connected through the receiving cavity 110 to increase the drainage volume.

[0059] like Figure 2 As shown, in some embodiments of this application, the moving piece 300 is provided with a cover 800 on the side opposite to the stationary piece 400, so as to seal the side of the receiving cavity 110 near the drain port 130 by the cover 800, thereby ensuring that the liquid can be discharged from the drain port 130.

[0060] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0061] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0062] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
