Pulling Faucet Inner Liner Structure for Noise and Flush-Out Control

The patent introduces a noise reduction structure as an intermediary component between the metal spring and metal support tube. This structure includes a first noise reduction component sleeved on the spring and a second noise reduction component disposed on the inner wall of the support tube, which contact each other to form a damping structure. The damping structure absorbs and dissipates the vibration and noise generated during the rubbing process, while still allowing the spring to perform its automatic restoration function.

The patent applies beforehand cushioning by designing an anti-flushing out structure that prevents the water outflow device from being separated under high pressure. This structure includes a limiting component that limits the movement distance of the water outflow device relative to the support tube, and a position limitation structure that works with the elastic restore member to constrain the water outflow device within a safe range, preventing it from being flushed out even when subjected to high water pressure.

The patent applies segmentation by dividing the connection system into multiple functional components: the inner tube, the support tube, the intermediate connector, and the position limitation structure. The position limitation structure specifically constrains the relative movement between the inner tube and support tube, preventing twisting and loosening during swinging, while the threaded connection provides assembly capability.
