Description

Technical Field

[0001] This utility model relates to the field of faucet technology, and in particular to a water outlet component and faucet. Background Technology

[0002] Currently, anti-splash faucets on the market typically consist of the faucet body and an aerator. The aerator is usually installed at the faucet spout and uses an internal mesh structure to reduce water consumption, achieving water conservation and splash prevention. However, with prolonged use, impurities and substances in the water accumulate and adhere to the inner wall of the faucet, especially on the aerator. This continuous buildup can lead to clogging or even damage to the faucet, affecting the user experience. Utility Model Content

[0003] This invention aims to at least partially solve one of the aforementioned technical problems in related technologies. To this end, this invention proposes a water outlet component that achieves a splash-proof effect and reduces clogging even without an aerator.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] This utility model also proposes a faucet having the above-mentioned water outlet component.

[0006] According to a first aspect of the present invention, a water outlet component includes a housing. Inside the housing, from top to bottom, are a flow-limiting plate, a splash guard, a flow rectifier, and a water outlet plate. The flow-limiting plate and the splash guard form a turbulent flow cavity, the splash guard and the flow rectifier form a flow rectifier cavity, and the flow rectifier and the water outlet plate form a water outlet cavity. The flow-limiting plate has a flow-limiting port communicating with the turbulent flow cavity. The splash guard includes a disc and multiple blocking columns. The disc has a turbulent flow zone and a water outlet zone. The water outlet zone is located on the outer periphery of the turbulent flow zone. The multiple blocking columns are spaced apart on the upper surface of the disc and located within the turbulent flow zone. The flow-limiting port is aligned with the turbulent flow zone.

The water outlet plate also has multiple water outlet holes.

[0007] The water outlet component according to the embodiment of this utility model has at least the following beneficial effects:

[0008] The water flow is controlled through a flow-limiting inlet, then enters the turbulent zone of the splash guard. The water is slowed down by collisions with multiple baffles, transforming the high-speed, concentrated flow into a low-speed, dispersed flow. During these collisions, kinetic energy is converted into frictional heat and the internal energy of turbulent flow, achieving pressure reduction and velocity reduction. Simultaneously, the water flow direction is controlled, flowing from the outlet on the outer periphery of the turbulent zone into the rectifier chamber, then through the rectifier holes into the outlet chamber, and finally out through the outlet holes. The rectifier plate further reduces the flow velocity and streamlines the water flow, minimizing splashing and ensuring uniform water distribution for excellent splash prevention. The outlet plate, with its multi-hole design, disperses the water flow, covering the area requiring cleaning more quickly.

[0011] According to some embodiments of this utility model, the height of the blocking posts on each step from the inside to the outside gradually increases, and the top of the blocking post on the outermost step abuts against the flow-limiting plate.

[0012] According to some embodiments of this utility model, the cross-sectional area of ​​the blocking columns on each step from the inside to the outside gradually increases.

[0013] According to some embodiments of the present invention, a busbar is provided inside the rectifier cavity, the busbar divides the rectifier cavity into an upper cavity and a lower cavity, and a funnel-shaped confluence port is provided in the middle of the busbar, the confluence port connecting the upper cavity and the lower cavity.

[0014] According to some embodiments of the present invention, the rectifier holes are distributed near the edge of the rectifier plate and arranged circumferentially along the rectifier plate.

[0015] According to some embodiments of this utility model, the rectifier hole and the outlet hole are staggered in the vertical direction.

[0016] According to some embodiments of this utility model, the outer shell is cylindrical and is integrally formed from a first annular wall and the water outlet plate.

[0027] Reference Figure 1-4A water outlet component includes a housing 100. Inside the housing 100, from top to bottom, are arranged a flow-limiting plate 200, a splash guard 300, a flow-rectifying plate 400, and a water outlet plate 110. The flow-limiting plate 200 and the splash guard 300 form a turbulent flow cavity 310, the splash guard 300 and the flow-rectifying plate 400 form a flow-rectifying cavity 410, and the flow-rectifying plate 400 and the water outlet plate 110 form a water outlet cavity 120. The flow-limiting plate 200 has a flow-limiting port 210 communicating with the turbulent flow cavity 310. The splash guard 300 encloses... The device includes a disc body 320 and multiple baffle posts 330. The disc body 320 has a turbulent flow zone and a water outlet zone. The water outlet zone is arranged around the outer periphery of the turbulent flow zone. Multiple baffle posts 330 are spaced apart on the upper surface of the disc body 320 and located within the turbulent flow zone. The flow limiting port 210 is aligned with the turbulent flow zone. The water outlet zone is provided with several water outlets 340, which are connected to the rectifier cavity 410. Multiple rectifier holes 420 are opened on the rectifier plate 400, which are connected to the water outlet cavity 120. Multiple water outlet holes 111 are opened on the water outlet plate 110.

[0028] Working principle: The water flow is controlled by the flow limit port 210, and then enters the turbulent zone of the splash guard 300. The water flow is decelerated by collision with multiple blocking columns 330, which transforms the high-speed concentrated water flow into a low-speed dispersed water flow. During the collision, the kinetic energy is converted into frictional heat and the internal energy of the water flow turbulence, achieving the effect of pressure reduction and speed reduction. At the same time, the water outlet direction is controlled so that the water flows from the outlet 340 on the outer periphery of the turbulent zone into the rectifier cavity 410, and then flows into the outlet cavity 120 through the rectifier hole 420, and finally flows out from the outlet hole 111. The rectifier plate 400 plays a role in further reducing the flow velocity and sorting the water flow, reducing splashing, ensuring the uniformity of water output, and achieving a good splash prevention effect.

[0029] In some embodiments of this invention, a multi-level step 321 arranged in a concentric ring is formed within the turbulent zone, and the height of each step 321 decreases progressively from the inside to the outside. Each step 321 is provided with multiple blocking posts 330 along its circumference. Furthermore, the flow-limiting port 210 is aligned with the innermost step 321. The multi-stage steps 321 decrease in height from the inside out, creating a graded expansion space that expands from narrow to wide and from high to low. After the water flows out of the flow-limiting outlet 210, it first impacts the innermost highest step 321. The space above the innermost highest step 321 is relatively compact. With each step 321 transitioning outward, the height of the step 321 decreases, and the lateral flow space of the water (i.e., the radial space of the turbulent zone) expands accordingly. The longitudinal space formed by the height difference of the steps 321 also increases simultaneously. The water flow can achieve a "small expansion" at each step 321, and the water pressure gradually decreases, achieving pressure reduction, expansion, and deceleration. The pressure reduction process is smooth. In addition, the multi-stage steps 321 guide the water flow from the center to the periphery in an orderly manner, transforming the high-speed concentrated water flow into a low-speed dispersed water flow.

[0030] In some embodiments of this utility model, the blocking post 330 is in the shape of a polygonal column. The side of a circular column is a smooth curved surface, and water flow is easy to slide along the curved surface after impact, resulting in a small effective collision area. In contrast, a polygonal column has multiple planar side surfaces and edges, and water flow will contact the side surfaces when it impacts, resulting in a larger contact area, which can more effectively intercept the water flow, consume more kinetic energy, and reduce speed more efficiently. The edges of the polygonal column are sharp corner structures, and the water flow is easily cut into smaller units by the edges, quickly dispersing the concentrated water flow.

[0031] In some embodiments of this invention, the height of the blocking posts 330 on each level of the steps 321 increases progressively from the inside out, with the top of the blocking post 330 on the outermost step 321 abutting against the flow-limiting plate 200. High-speed water flow impacts the innermost step 321 and splashes outwards. Because the outermost blocking posts 330 are higher, the splashing water flow is slowed down by the collisions with multiple levels of blocking posts 330. The blocking post 330 on the outermost step 321 acts as the final barrier, ensuring that the water flow is slowed down and dispersed.

[0032] In some embodiments of this utility model, the cross-sectional area of ​​the blocking posts 330 on each step 321 from the inside to the outside gradually increases.

[0033] In some embodiments of this utility model, a manifold 500 is provided inside the rectifier cavity 410, which divides the rectifier cavity 410 into an upper cavity 411 and a lower cavity 412. A funnel-shaped confluence port 510 is provided in the middle of the manifold 500, which connects the upper cavity 411 and the lower cavity 412. Water flows into the manifold 500 from the outlet 340 and passes through the confluence port 510. The confluence port 510 plays a certain role in sorting the water flow, making the water flow more concentrated and continuous, avoiding dispersion and branching. In addition, the confluence port 510 ensures that the water flows smoothly along the preset path to the rectifier hole 420, reducing splashing.

[0034] In some embodiments of this utility model, the rectifier holes 420 are distributed near the edge of the rectifier plate 400 and arranged circumferentially along the rectifier plate 400. The water flows from the confluence port 510 to the middle of the rectifier plate 400, and then diffuses radially outward, flowing out from the rectifier holes 420 near the edge. This process prolongs the water flow path and further reduces the flow velocity.

[0035] In some embodiments of this utility model, the rectifier hole 420 and the outlet hole 111 are staggered in the vertical direction. The water flow from the rectifier hole 420 first hits the outlet plate 110 and then flows to the outlet hole 111, consuming kinetic energy again and reducing the flow velocity.

[0036] In some embodiments of this utility model, the outer shell 100 is cylindrical and integrally formed from a first annular wall 130 and a water outlet plate 110. A second annular wall 220 is provided around the outer periphery of the flow-limiting plate 200, a third annular wall 350 is provided around the outer periphery of the splash guard 300, and a fourth annular wall 430 is provided around the outer periphery of the rectifier plate 400. A positioning protrusion 131 is provided on the inner peripheral wall of the first annular wall 130. The second annular wall 220, the third annular wall 350, and the fourth annular wall 430 are embedded within the first annular wall 130 and stacked sequentially from top to bottom. The lower end of the fourth annular wall 430 abuts against the positioning protrusion 131. The second annular wall 220, the third annular wall 350, and the fourth annular wall 430 form a continuous support chain in the axial direction, facilitating the axial positioning of the flow-limiting plate 200, the splash guard 300, and the rectifier plate 400. This nested structure allows for tool-free, rapid assembly.

[0037] A faucet includes the aforementioned water outlet component, which is installed at the water outlet end of the faucet.
