Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment technology, and in particular to a faucet aerator. Background Technology

[0002] An aerator is a device that creates a foaming effect on the water flow and saves water. An aerator allows the water and air to mix thoroughly, resulting in a larger contact area and a gentler, splash-free water flow when washing hands. It enhances the rinsing power of the water while maintaining a smooth, splash-free spray, thus meeting people's needs for a better water experience. However, existing aerators only have a foaming function and cannot adjust the flow rate or switch to other water outlet modes, making their functionality limited and their applicability poor.

[0003] The applicant previously filed a Chinese utility model patent with authorization announcement number CN219219235U, which discloses an aerator, including a shell and a water inlet, a water passage component, and a water outlet component arranged sequentially inside the shell. The upper end of the shell has an opening corresponding to the position of the water inlet, and the bottom of the shell has a first water outlet area and a second water outlet area. The second water outlet area is located on the outer periphery of the first water outlet area. The water inlet has a water inlet hole and a connecting section. The water passage component is rotatably connected to the water inlet. The lower end of the water passage component has a water outlet. The water outlet component is located between the water passage component and the bottom wall of the shell. The water outlet component has a first water outlet channel communicating with the first water outlet area. A second water outlet channel communicating with the second water outlet area is formed between the water outlet component and the inner side wall of the shell at intervals. Rotating the water inlet component controls the water outlet to communicate with the first water outlet channel or with the second water outlet channel. A sealing element is provided at the bottom of the water outlet component between the first water outlet area and the second water outlet area.

[0004] The aforementioned structure has numerous components, making assembly inconvenient and inefficient. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects of the prior art by providing a faucet aerator that reduces the number of parts, making the structure simpler and the assembly efficiency higher.

[0006] The technical solution of this utility model: A faucet aerator includes a housing and an inlet and an outlet component disposed within the housing. The inlet and outlet components are rotatably connected. The inlet component has an inlet port. The bottom wall of the housing has a first outlet area and a second outlet area. The outlet component is located between the inlet component and the bottom wall of the housing. The outlet component has a first outlet channel corresponding to the first outlet area. A second outlet channel is formed between the outlet component and the side wall of the housing, corresponding to the second outlet area. The bottom of the outlet component is located at the first outlet area. A sealing element is provided between the water zone and the second water outlet zone. The water inlet includes an integrally formed connecting part and a water filter part. The water inlet is located on the connecting part. The water filter part is hollow. The bottom of the water filter part is provided with a water outlet that communicates with the hollow part. The water filter part is provided with a water outlet channel and several slots. The water outlet channel communicates with the water inlet. The water outlet channel communicates with the hollow part through each slot. A filter element is sleeved on the outside of the water filter part at the corresponding slot position. When the water inlet and the water outlet rotate relative to each other, the water outlet can be driven to communicate with the first water outlet channel or with the second water outlet channel.

[0007] By adopting the above technical solution, the connecting part and the water filter part are integrally formed, reducing the number of parts and making the aerator easier to assemble. It can be quickly disassembled and assembled, solving the problem of numerous parts and complicated assembly in the existing technology. When in use, the connecting part is connected to the faucet, or it can be connected through the universal ball joint assembly to achieve 360-degree rotation. The water from the faucet enters from the inlet, then flows out from the outlet channel, and after being filtered by the filter element, it enters the hollow part from the slot and then flows out from the outlet. With the relative rotation of the inlet and outlet parts, the water can flow from the first outlet channel to the first outlet area, or from the second outlet channel to the second outlet area. The shower mode or aeration mode can be switched.
