What is the design principle of Metal Kitchen Pull-Out Hose? How to implement stretch and telescopic functions?

The design principle of the Metal Kitchen Pull-Out Hose is based on the mechanism of a telescopic hose, which achieves the function of stretching and retracting through the internal structure and material properties. This kind of hose is made of metal material, has good elasticity and durability, can withstand tensile and compressive forces, and is not easy to deform. The inside of the hose is designed with a spiral structure, similar to the principle of a coil spring. This design makes the hose flexible enough to curl compactly inside the faucet when not in use, saving space and keeping things tidy.

When the user needs to use the nozzle, they simply apply a slight pull and the hose's spiral structure unfolds and the hose extends from the inside of the faucet to provide the desired length. This stretch mechanism allows the hose to remain stable while in use while providing sufficient length to meet a variety of cleaning needs. When the nozzle is no longer needed, the hose automatically shrinks and returns to the inside of the faucet through its elastic spiral structure, keeping it neat and compact. This telescopic mechanism prevents the hose from taking up too much space when not in use, while also effectively protecting the hose from damage.

In addition, the Metal Kitchen Pull-Out Hose's connectors and seals are designed to ensure a secure connection between the hose and the faucet and no leakage. Ensure that the hose can maintain stable and reliable performance during use.
