[0002] With the improvement of life quality, people's comfort requirement of home environment is increasing, and the use experience of faucet becomes the focus. When the traditional faucet is out of water, due to water flow impact and pipeline vibration, it often generates a large noise, especially at night or in a quiet environment, which will affect the user's use experience. In addition, the outer wall of the ordinary faucet water outlet pipe is easy to heat when conveying hot water, and there is a risk of scalding, and the single-layer metal or plastic pipe structure is difficult to effectively suppress water flow noise.

[0003] The current market mute faucet mainly adopts the following several noise reduction ways:

[0004] 1. Single-layer pipeline + sound-absorbing cotton: paste sound-absorbing material on the inner wall of metal or plastic pipe, but the noise reduction effect is limited, and the sound-absorbing material is easy to age and fall off after long-term use.

[0005] 2. Buffer chamber design: set buffer chamber at the water outlet to reduce water flow impact, but the structure is complex, and the high-frequency noise suppression is insufficient.

[0006] 3. Double-layer pipe structure: some high-end products adopt double-layer pipe design, but usually only rely on air layer sound insulation, and the noise reduction effect is not significant, and lacks optimization for water flow turbulence noise.

[0007] But the existing technology has the following problems:

[0008] 1. Poor noise reduction effect: single-layer pipeline or simple double-layer structure cannot effectively absorb wideband noise (such as water flow impact sound, pipeline resonance sound).

[0009] 2. Insufficient heat insulation performance: when conveying hot water, the outer wall temperature is high, which has safety hazards.

[0010] 3. Insufficient structural strength and durability: some mute designs sacrifice the mechanical strength of the pipeline, which is easy to deform or break after long-term use.

[0011] Therefore, a new type of faucet water outlet pipe structure is needed, which can effectively reduce noise while ensuring smooth water flow, and has good heat insulation performance and structural stability to meet the needs of high-end home and commercial scenarios. Utility model content
