Description

Technical Field

[0001] This application relates to the field of liquid switch technology, and more particularly to an adjustable liquid switch. Background Technology

[0002] Adjustable liquid switches are switching devices mounted on hoses. However, there are very few existing hose-mounted switches. Some are inconvenient to operate with one hand, some have a diameter at the switch that is smaller than the diameter of the water pipe, some cannot be adjusted, and water will still leak out from the joint when the switch is half closed. Summary of the Invention

[0003] This application discloses an adjustable liquid switch, comprising: a main body, an upper connector, a leak-proof plate, and a switch plate. The upper connector is disposed on the main body and is used to connect a flexible hose. The main body has an assembly chamber and an assembly groove. The leak-proof plate is disposed in the assembly groove and prevents liquid from flowing out. When the switch plate is pushed, the through hole on the switch plate shifts, ensuring that liquid does not flow out. The assembly chamber is used to assemble the switch plate, and the switch plate is in close contact with the leak-proof plate. The main body, upper connector, leak-proof plate, and switch plate are all provided with through holes to allow liquid to pass through. Pushing the switch plate can adjust the flow rate or turn it off.

[0004] Furthermore, the adjustable liquid switch also includes a lower connector for connecting a hose. The lower connector is connected to the bottom of the main body and has a through hole inside.

[0005] Furthermore, the switch piece is reinforced to prevent deformation and breakage, thereby reducing the thickness of the switch piece and reducing processing time. The reinforcement is located on the edge of the switch piece.

[0006] Furthermore, the main body is also provided with a limit switch to facilitate the switch being opened to the maximum or closed, and the limit switch is provided on the main body.

[0007] Furthermore, the leak-proof sheet is provided with a deformation groove to reduce the useless pushing force of the middle part of the leak-proof sheet on the switch piece, making it easier to push the switch piece, and the deformation hole is provided on one side of the leak-proof sheet.

[0008] Furthermore, the through hole of the switch piece is located in the middle of the switch piece, so there is no need to consider the direction during installation.

[0009] Furthermore, the main body is processed separately and then fixed together. The joint between the separate parts is provided with grooves, which makes it difficult to shift during installation, increases the welding surface, and increases the welding firmness. Attached Figure Description

[0023] like Figure 1 — Figure 12As shown, this application embodiment provides an adjustable liquid switch, including: a main body 1, an upper connector 2, a leak-proof plate 3, and a switch plate 4. The upper connector 2 is disposed on the main body 1 for connecting a hose. The main body 1 is provided with an assembly chamber 5 and an assembly groove 6. The leak-proof plate 3 prevents liquid from flowing out. When the switch plate 4 is pushed to adjust the flow rate, the through hole 7 on the switch plate 4 moves to one side to ensure that the liquid does not flow out. The leak-proof plate 3 is disposed in the assembly groove 6. The assembly chamber 5 is used to assemble the switch plate 4, and the switch plate 4 is in close contact with the leak-proof plate 3. The main body 1, the upper connector 2, the leak-proof plate 3, and the switch plate 4 are all provided with through holes 7 to allow liquid to pass through. In use, the upper connector 2 is installed into the hose, and the liquid flows from the through hole 7 in the hose to the through hole in the switch plate 4, and then flows out from the through hole 7 under the main body 1. Pushing the switch plate 4 can adjust the flow rate or close it.

[0024] like Figure 4 — Figure 9 As shown, the adjustable liquid switch also includes a lower connector 8, which is used to connect a hose. The lower connector 8 is connected to the bottom of the main body 1, and a through hole 7 is provided in the lower connector 8 to allow liquid to pass through.

[0025] like Figure 7 , Figure 8 , Figure 9 , Figure 11 As shown, the switch piece 4 is provided with a reinforcing rib 9 to prevent the switch piece 4 from deforming or breaking, thereby reducing the thickness of the switch piece 4, thus reducing processing time and lowering costs. The reinforcing rib 9 is provided on the side of the switch piece 4.

[0026] like Figure 7 , Figure 8 , Figure 9 , Figure 11 As shown, the main body 1 is also provided with a limit switch 10 to facilitate the switch being opened to the maximum or closed. The limit switch 10 is located on the main body 1. When the switch piece 4 is pushed to the right to the end, the reinforcing 9 of the switch piece 4 hits the limit switch 10 on the main body 1 and cannot move forward. At this time, the through hole 7 of the switch piece just overlaps with the through hole 7 on the main body 1, and the flow rate is the maximum. When pushed to the left to the end, the reinforcing 9 of the switch piece 4 hits the limit switch 10 on the main body 1 and cannot move forward. At this time, the through hole of the switch piece 4 just leaves the through hole 7 of the anti-leakage piece 3 and the switch is closed.

[0027] like Figure 10 As shown, the leak-proof plate 3 is provided with a deformation groove 11. Under the pressure of the switch plate 4, the solid part of the leak-proof plate 3 moves into the deformation groove 11, reducing the useless pushing force of the middle part of the leak-proof plate 3 on the switch plate 4, reducing the friction between the leak-proof plate 3 and the switch plate 4, and facilitating the pushing of the switch plate 4. The deformation groove 11 is provided on one side of the leak-proof plate 3.

[0028] like Figure 11 As shown, the through hole 7 of the switch piece 4 is located in the middle of the switch piece 4, so there is no need to consider the direction during installation.

[0029] like Figure 4 , Figure 5 , Figure 12 As shown, the main body 1 is further processed in separate parts and then fixed together. The joint of the parts is provided with grooves 12, which makes it difficult to shift during installation, increases the welding surface, and ensures the welding firmness.
