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.

[0026] Example 1:

[0027] like Figures 1 to 7 As shown, a water-saving device includes an inlet hose 5 and an angle valve 1. A water-saving valve 2 is connected between the inlet hose 5 and the angle valve 1. The water-saving valve 2 has a first cylinder 201 and a second cylinder 202. The diameter of the first cylinder 201 is smaller than the diameter of the second cylinder 202. The first cylinder 201 and the second cylinder 202 are coaxially connected. The first cylinder 201 and the second cylinder 202 have stepped through holes 203 inside.

[0028] Preferably, the stepped through hole 203 has a first axial through hole 2031 extending axially inward from the outer end of the first cylinder 201. The first axial through hole 2031 is connected to a first radial through hole 2034 at one end away from the outer end of the first cylinder 201. The first radial through hole 2034 is connected to a second axial through hole 2032 at one end away from the first axial through hole 2031. The second axial through hole 2032 is connected to a second radial through hole 2035 at one end away from the first radial through hole 2034. The second radial through hole 2035 is connected to a third axial through hole 2033 at one end away from the second axial through hole 2032.

[0029] Preferably, an angle valve connector 4 connects the inlet hose 5 and the angle valve 1, and the water-saving valve 2 is disposed inside the angle valve connector 4. Preferably, a rubber gasket 3 is provided between the water-saving valve 2 and the inlet hose 5 and the angle valve 1. Preferably, the stepped through hole 203 has a cross-section that is a semi-circular groove with an upward opening. This utility model mainly reduces pressure through this smaller outlet, and there are some baffles in this through hole.

[0030] In this embodiment of a water-saving device, the angle valve 1 connects to the water pipe (water source) and can turn the water source on and off. The water pressure can be adjusted via a knob on its head. The rubber gasket 3 protects the water-saving valve 2 and prevents leakage at its installation location. The water-saving valve 2, through its internal structure, reduces water pressure and thus lowers the water flow rate. The angle valve connector 4 is an intermediate component connecting the angle valve 1 and the inlet hose 5. At its intermediate position with the angle valve 1, the rubber gasket 3 locks the water-saving valve 2 in place. The inlet hose 5 has a lower nut that engages with the angle valve connector 4, and an upper connector that connects to the faucet, primarily delivering water to the faucet.

This invention mainly reduces pressure through this smaller outlet, while some baffles in this through hole slow down the water flow.

[0033] Preferably, the water-saving valve 2 is manufactured using FDM (Fused Deposition Modeling) 3D printing. Preferably, the material used for the water-saving valve 2 is PLA printing material, which is food-grade. The manufacturing process of this product is as follows: first, the designed part is pre-printing parameter settings are configured; then, the data is imported into the printer for printing; finally, the model is created.

[0034] By analyzing the relationship between water pressure and flow rate, this utility model utilizes digital design and manufacturing methods to design and manufacture a water-saving device including an angle valve 1 adapter internal pressure reducing connector, realizing the principle that water flow in public areas can be used for handwashing without waste, reducing the water flow rate from the original 24L per minute to 4.37L.

[0035] The water-saving valve 2 of this utility model adopts a semi-circular stepped design to prevent clogging during use, thus achieving pressure reduction while ensuring no clogging. Furthermore, considering the actual installation environment, a stepped cylindrical external shape is used for ease of installation.
