[0002] Faucets, as an indispensable pipe fitting in our daily lives, are usually installed at the end of water pipes to turn the water flow on or off. Anti-splash faucets are carefully improved and upgraded based on ordinary faucets. Through various designs, they reduce the impact of water flow and can effectively reduce or prevent water splashing.

[0003] Traditional faucets have the problem of not being able to adjust the water flow rate. Different usage scenarios require different water flow intensities. Excessive water flow may cause water to splash, wetting clothes or the surrounding environment and causing discomfort. Insufficient water flow may result in incomplete cleaning and waste time.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] In one embodiment, such as Figures 1-3 As shown, a splash-proof faucet includes a valve seat 100, a water outlet pipe 200, and a splash-proof assembly. The water outlet pipe 200 is located below one end of the valve seat 100. The splash-proof assembly includes an inlet section 301, which is located on the end of the water outlet pipe 200 away from the valve seat 100 and is connected to the water outlet pipe 200. A throat section 302 is connected to the end of the inlet section 301 away from the water outlet pipe 200. One end of the inlet section 301 is connected to the diffuser section 303. The throat section 302 is equipped with an adjustment component to adjust the cross-sectional area of ​​the throat section 302. Water is guided into the inlet section 301 through the outlet pipe 200 and then into the throat section 302. Subsequently, due to the decrease in channel area, the water flow velocity increases according to the principle of fluid continuity (mass conservation). Then, it reaches the diffuser section 303, where the channel area gradually increases and the water flow velocity gradually decreases, thereby preventing water splashing.

[0024] In one embodiment, such as Figure 2 and Figure 3 As shown, the adjusting assembly includes a first connecting rod 401, which is located at one end inside the throat section 302. A second connecting rod 402 is rotatably connected to the top of the first connecting rod 401. A valve plate 403 is provided at the end of the second connecting rod 402 away from the first connecting rod 401. Baffles 404 are provided at both ends inside the throat section 302, and the valve plate 403 is movably abutted against the two baffles 404. A rotating assembly is provided inside the throat section 302 to drive the valve plate 403 to rotate. By rotating the valve plate 403, the second connecting rod 402 is subsequently driven to rotate on the first connecting rod 401.

[0025] In one embodiment, such as Figure 2 and Figure 3As shown, the rotating assembly includes a rotating seat 501, which is located on the end of the valve plate 403 away from the baffle 404. A third connecting rod 502 is rotatably connected inside the rotating seat 501. A fourth connecting rod 503 is rotatably connected to the bottom of the end of the third connecting rod 502 away from the rotating seat 501. The fourth connecting rod 503 is slidably connected inside the throat section 302. A driving assembly for moving the fourth connecting rod 503 is provided at one end of the throat section 302. By pulling the fourth connecting rod 503, the third connecting rod 502 is rotated, thereby causing the rotating seat 501 and the valve plate 403 to rotate.

[0026] In one embodiment, such as Figure 2 and Figure 3 As shown, the drive assembly includes a support plate 601, which is disposed on one end of the throat section 302. A bending member 602 is rotatably connected to the top of the support plate 601. One end of the fourth connecting rod 503 is disposed inside the bending member 602. A limiting groove 603 is formed on the end of the bending member 602 near the fourth connecting rod 503. A limiting post 604 is fixedly connected inside the fourth connecting rod 503, and the limiting post 604 is disposed inside the limiting groove 603. By bringing one end of the bending member 602 close to the throat section 302, the limiting post 604 is driven to move inside the limiting groove 603, thereby driving the fourth connecting rod 503 away from the throat section 302.

[0027] In one embodiment, such as Figure 3 As shown, tension springs 700 are provided on both ends of the bent member 602 near the throat section 302. When one end of the bent member 602 is close to the throat section 302, the other end will move away from the throat section 302. Then, when the pushing force on the bent member 602 is removed, the bent member 602 will be driven to reset under the action of the tension springs 700.

[0028] In one embodiment, such as Figure 1 As shown, the water outlet pipe 200 is a corrugated pipe, which facilitates direction adjustment.

[0029] In one embodiment, such as Figure 1 As shown, an aerator 800 is installed at the bottom of the valve seat 100, and the bottom of the aerator 800 is connected to the water outlet pipe 200 to reduce the impact force of the water flow.

[0030] In one embodiment, such as Figure 3 As shown, a sealing gasket is provided at the point where the fourth connecting rod 503 contacts the throat section 302 to prevent water leakage.

[0031] The above embodiment discloses an anti-splash faucet, in which water is guided through the outlet pipe 200 to the inlet section 301, then to the throat section 302. Subsequently, due to the decrease in channel area, the water flow velocity increases according to the principle of fluid continuity (mass conservation). Then, reaching the diffuser section 303, the channel area gradually increases, and the water flow velocity gradually decreases. When the water flow velocity increases, its pressure decreases; conversely, when the velocity decreases, the pressure increases. Therefore, in the throat section 302, the water flow velocity is the highest and the pressure is the lowest; in the diffuser section 303, the water flow velocity decreases and the pressure increases. The pressure change helps control the shape of the water flow, reduce water flow turbulence, and thus prevent water splashing. It can also bring one end of the bent part 602 closer to the throat section 302, and then drive the limiting post 604 to move inside the limiting groove 603, thereby driving the fourth link 503 away from the throat section 302, thereby driving the third link 502 to rotate, thereby driving the rotating seat 501 and the valve plate 403 to rotate, and then driving the second link 402 to rotate on the first link 401, thereby changing the cross-sectional area inside the throat section 302, thereby controlling the pressure inside the valve.

[0032] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
