Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0038] Example 1:

[0039] like Figure 4-6 As shown, this embodiment provides a flow control structure 100, which is installed on a pipe 1, and the pipe 1 has a medium channel 11. The flow control structure 100 includes a blocking member 2 and an adjusting member 3. The blocking member 2 is rotatably connected to the pipe 1 and is located in the medium channel 11. The adjusting member 3 is installed on the pipe 1 and is used to control the rotation of the blocking member 2 so that the blocking member 2 controls the flow rate of the fluid in the medium channel 11.

[0040] In this embodiment, the flow control structure 100 is installed on the pipeline 1 to block or partially block the medium channel 11 inside the pipeline 1. The blocking member 2 forms a flow port between the medium channel 11 and the inner wall of the pipeline 1 to adjust the size of the flow port of the medium channel 11 inside the pipeline 1, thereby controlling the flow rate of the fluid inside the medium channel 11. Specifically, the flow control structure 100 includes a blocking member 2 and an adjusting member 3. The blocking member 2 is located inside the medium channel 11, and the adjusting member 3 can control the rotation of the blocking member 2. When it is necessary to increase the fluid flow rate of the medium channel 11, the adjusting member 3 controls the blocking member 2 to rotate relative to the pipeline 1. The rotation of the blocking member 2 increases the flow port diameter of the medium channel 11, thereby increasing the fluid flow rate through the flow port, that is, increasing the amount of fluid flowing out of the pipeline 1. When it is necessary to decrease the fluid flow rate of the medium channel 11, the adjusting member 3 controls the blocking member 2 to decrease the flow port diameter of the medium channel 11, thereby decreasing the fluid flow rate through the flow port, and thus reducing the amount of fluid flowing out of the pipeline 1. By controlling the sealing component 2 to block the medium channel 11 in the pipe 1 through the adjusting component 3, the flow diameter of the medium channel 11 can be adjusted, thereby achieving efficient control of the flushing force and flow rate of the first and second spray arms of the spray cleaning system. This results in a balanced and stable flushing force and flow rate of the first and second spray arms, thereby improving the washing effect and efficiency of the tableware.

[0041] like Figure 1 and 2 As shown, when this flow control structure 100 is applied to a dishwasher, the flow control structure 100 is installed on the spray arm or other pipe 1 of the spray cleaning system to control the size of the flow opening in the spray arm or other pipe 1, so as to ensure that the water sprayed from the spray arm is appropriate and effectively avoid the dishwasher wasting water.

[0042] As another embodiment, this flow control structure 100 can also be applied to other devices that require flow control in order to control the fluid flowing out of the device and avoid fluid waste.

[0043] like Figure 5 and 6 As shown, the sealing component 2 includes a sealing plate 21 and a rotating shaft 22. The sealing plate 21 is fixedly connected to the rotating shaft 22, and the rotating shaft 22 is rotatably connected to the pipe 1. By rotating the rotating shaft 22, the sealing plate 21 can adjust the diameter of the medium channel 11 to control the flow rate of the fluid in the medium channel 11.

[0044] In this embodiment, the sealing plate 21 is fixedly connected to the rotating shaft 22, which is rotatably connected inside the pipe 1. When it is necessary to adjust the flow diameter of the medium channel 11 inside the pipe 1, the rotating shaft 22 is controlled to rotate by the adjusting component 3, causing the sealing plate 21 to rotate inside the medium channel 11. The sealing plate 21 adjusts the diameter of the medium channel 11, thereby adjusting the flow diameter and controlling the flow rate of the fluid inside the medium channel 11. It can be understood that to increase the flow rate of the fluid inside the medium channel 11, rotating the sealing plate 21 increases the flow diameter, thus increasing the flow rate; conversely, to decrease the flow rate of the fluid inside the medium channel 11, rotating the sealing plate 21 decreases the flow diameter.

[0045] like Figure 5 and 6 As shown, the adjusting component 3 includes an adjusting plate 31 and a fixing component 32. The rotating shaft 22 is rotatably connected inside the pipe 1 and both ends of the rotating shaft 22 extend to the outer side of the pipe 1. The adjusting plate 31 is fixedly connected to one end of the rotating shaft 22. The adjusting plate 31 can drive the rotating shaft 22 to rotate. The fixing component 32 is used to fix the adjusting plate 31 to the pipe 1.

[0046] In this embodiment, the adjusting plate 31 is fixedly connected to one end of the rotating shaft 22. The adjusting plate 31 can drive the rotating shaft 22 to rotate. When it is necessary to adjust the flow rate of the fluid in the medium channel 11 in the pipeline 1, by rotating the adjusting plate 31, the adjusting plate 31 drives the rotating shaft 22 to rotate, which in turn drives the sealing plate 21 to rotate, thereby adjusting the flow diameter in the medium channel 11 and realizing the control of the flow rate of the fluid in the medium channel 11 by the sealing plate 21. When the flow rate of the fluid flowing out of the medium 1 reaches the required level, the adjusting plate 31 is fixed to the pipeline 1 by the fixing member 32, which effectively restricts the rotating plate from rotating again, so as to keep the flow rate of the fluid flowing out of the pipeline 1 constant.

[0047] like Figure 5 and 6 As shown, the fixing member 32 includes a fixing bolt 321 and a fixing nut 322 adapted to the fixing bolt 321. The fixing bolt 321 is fixedly connected to the pipe 1. The adjusting plate 31 has an arc-shaped groove 311. The end of the fixing bolt 321 away from the pipe 1 passes through the arc-shaped groove 311. The fixing nut 322 locks the adjusting plate 31 onto the fixing bolt 321.

[0048] In this embodiment, the fixing bolt 321 is fixed to the pipe 1. The end of the fixing bolt 321 away from the pipe 1 passes through the arc groove 311 on the adjusting plate 31. When it is necessary to fix the sealing plate 21, the fixing nut 322 presses the adjusting plate 31 and locks the adjusting plate 31 onto the fixing bolt 321, thereby fixing the sealing plate 21. When it is necessary to adjust the flow diameter in the medium channel 11, the fixing nut 322 loosens the adjusting plate 31, the adjusting plate 31 is rotated, the fixing bolt 321 slides in the arc groove 311, the adjusting plate 31 rotates, and the sealing plate 21 rotates, thereby adjusting the flow diameter in the medium channel 11.

[0049] Example 2:

[0050] like Figure 1-3 As shown, this embodiment provides a spray assembly, including a water inlet pipe 4, a first connecting pipe 5, a second connecting pipe 6, a first spray arm structure 7, and a second spray arm structure 8; the water inlet pipe 4 has a water inlet 41; the first connecting pipe 5 is installed at the end of the water inlet pipe 4 near the water inlet 41, and the first connecting pipe 5 is connected to the water inlet pipe 4, and the first connecting pipe 5 is provided with the flow control structure 100 described in Embodiment 1; the second connecting pipe 6 is installed at the end of the water inlet pipe 4 away from the water inlet 41, and the second connecting pipe 6 is connected to the water inlet pipe 4, and the end of the water inlet pipe 4 near the second connecting pipe 6 is provided with the flow control structure 100 described in Embodiment 1; the first spray arm structure 7 is installed at the end of the first connecting pipe 5 away from the water inlet pipe 4, and the first spray arm structure 7 is connected to the first connecting pipe 5; the second spray arm structure 8 is installed at the end of the second connecting pipe 6 away from the water inlet pipe 4, and the second spray arm structure 8 is connected to the second connecting pipe 6.

[0051] In this embodiment, the water inlet pipe 4 has an inlet 41 through which water can enter the water inlet pipe 4. A first connecting pipe 5 is installed at the end of the water inlet pipe 4 near the inlet 41 and is connected to the water inlet pipe 4. A second connecting pipe 6 is installed at the end of the water inlet pipe 4 away from the inlet 41 and is connected to the water inlet pipe 4. A first spray arm structure 7 is installed at the end of the first connecting pipe 5 away from the water inlet pipe 4 and is connected to the first connecting pipe 5. A second spray arm structure 8 is installed at the end of the second connecting pipe 6 away from the water inlet pipe 4 and is connected to the second connecting pipe 6. Preferably, the first... The connecting pipe 5 is a straight pipe, and the second connecting pipe 6 is a bent pipe, so that the first spray arm structure 7 and the second spray arm structure 8 are opposite each other, forming a spray space between the first spray arm structure 7 and the second spray arm. Water can enter the water inlet pipe 4 through the water inlet 41 and then be divided into the first connecting pipe 5 and the second connecting pipe 6. The divided water flows through the first connecting pipe 5 to the first spray arm structure 7 and through the second connecting pipe 6 to the second spray arm structure 8. The first spray arm structure 7 and the second spray arm structure 8 respectively spray water into the spray space between the first spray arm structure 7 and the second spray arm structure 8, thereby spraying and cleaning the dishes placed in the spray space. Since the first connecting pipe 5 is equipped with the flow control structure 100 of Embodiment 1, the first connecting pipe 5 is the same as the pipe 1 in Embodiment 1. The flow control structure 100 controls the water flow in the first connecting pipe 5, thereby controlling the water flow to the first spray arm structure 7, so that a suitable amount of water is sprayed through the first spray arm to clean the dishes; the end of the water inlet pipe 4 near the second connecting pipe 6 is also equipped with the flow control structure 100 of Embodiment 1. In this case, the water inlet pipe 4 is the same as the pipe 1 in Embodiment 1, and the flow control structure 100 controls the water flow in the second connecting pipe 6. Furthermore, the water flow rate to the second spray arm structure 8 is controlled to ensure that an appropriate amount of water is sprayed through the second spray arm to clean the dishes. This spray assembly controls the flow rate to the first and second spray arms through the flow control structure 100 of Embodiment 1, so that an appropriate amount of water is sprayed from the first and second spray arms to clean the dishes. This achieves efficient control of the scouring force and flow rate of the fluid sprayed from the first and second spray arms, and achieves a balance and stability of the scouring force and flow rate of the first and second spray arms, thereby improving the washing effect and efficiency of the tableware.

[0052] like Figure 1-3As shown, the first spray arm structure 7 includes a first through pipe 71 and a plurality of first spray pipes 72 disposed on and connected to the first through pipe 71; one end of the first through pipe 71 is connected to the end of the first connecting pipe 5 away from the water inlet pipe 4, and the end of the first through pipe 71 away from the first connecting pipe 5 has a closed opening; the plurality of first spray pipes 72 are evenly arranged in the axial direction of the first through pipe 71, and the first spray pipes 72 are provided with a plurality of first spray holes 721, which are evenly arranged in the axial direction of the first spray pipes 72.

[0053] In this embodiment, one end of the first pipe 71 is connected to the end of the first connecting pipe 5 away from the water inlet pipe 4. The end of the first pipe 71 away from the first connecting pipe 5 has a closed opening. A plurality of first spray pipes 72 are evenly arranged in the axial direction of the first pipe 71. When the water flow is diverted from the water inlet pipe 4 to the first connecting pipe 5, it flows through the first connecting pipe 5 to the first pipe 71, and finally enters and exits the first spray pipe 72 through the first pipe 71. Since the first spray pipe 72 is provided with a plurality of first spray holes 721, and the plurality of first spray holes 721 are evenly arranged in the axial direction of the first spray pipe 72, the water flowing into the first spray pipe 72 is sprayed out through the plurality of first spray holes 721, thereby spraying and cleaning the dishes, realizing the function of the first spray arm structure 7 in spraying and cleaning the dishes.

[0055] In this embodiment, one end of the second pipe 81 is connected to the end of the second connecting pipe 6 away from the water inlet pipe 4. The end of the second pipe 81 away from the second connecting pipe 6 has a closed opening. A plurality of second spray pipes 82 are evenly arranged in the axial direction of the second pipe 81. When the water flow is diverted from the water inlet pipe 4 to the second connecting pipe 6, it flows through the second connecting pipe 6 to the second pipe 81, and finally enters and exits the second spray pipe 82 through the second pipe 81. Since the second spray pipe 82 is provided with a plurality of second spray holes 821, and the plurality of second spray holes 821 are evenly arranged in the axial direction of the second spray pipe 82, the water flowing into the second spray pipe 82 is sprayed out through the plurality of second spray holes 821, thereby spraying and cleaning the dishes, realizing the function of the second spray arm structure 8 in spraying and cleaning the dishes.

[0057] In this embodiment, the first connecting pipe 5 is a straight pipe, and the second connecting pipe 6 is a bent pipe. After the first through pipe 71 and the second through pipe 81 are connected to the first connecting pipe 5 and the second connecting pipe 6 respectively, the first through pipe 71 and the second through pipe 81 are arranged opposite to each other. The first spray pipe 72 connected to the first through pipe 71 and the second spray pipe 82 connected to the second through pipe 81 form opposite faces, forming a spray space in the middle. The first spray hole 721 is arranged facing the second spray pipe 82, and the second spray hole 821 is arranged facing the first spray pipe 72. After the water flows out through the first spray hole 721 and the second spray hole 821, it sprays and cleans the bowls placed in the spray space. The first spray pipes 72 and the second spray pipes 82 are staggered so that the water sprayed from the first spray pipes 72 and the second spray pipes 82 is staggered, so that the bowls are sprayed and cleaned more thoroughly and the bowls are cleaned.

[0058] like Figure 3 As shown, the first connecting pipe 5 has a first connecting portion 51 at the end away from the water inlet pipe 4, and the first through pipe 71 has a first insertion portion 711 at the end near the first connecting pipe 5. The first insertion portion 711 is inserted into the first connecting portion 51, and a first sealing ring 712 is provided between the first insertion portion 711 and the first connecting portion 51. The second connecting pipe 6 has a second connecting portion 61 at the end away from the water inlet pipe 4, and the second through pipe 81 has a second insertion portion 811 at the end near the second connecting pipe 6.
