[0004] In order to achieve the above purpose, the technical solution adopted by the present invention is: a tube core, including a retractable hose, the water inlet end and the water outlet end of the hose are respectively connected to a first pipe liner and a second pipe liner, the first pipe liner and the second pipe liner are both provided with through holes connected to the internal channel of the hose, stretching the hose can make the first pipe liner move away from the second pipe liner, and contracting the hose can make the first pipe liner and the second pipe liner move closer to each other.

[0005] Compared to the existing technology, the advantages of the present invention lie in its use of a retractable hose, allowing the tube core to be freely adjusted between different lengths. This design greatly enhances the tube core's flexibility in practical applications, enabling it to adapt to a variety of usage scenarios and space requirements. Users can easily extend or retract the hose as needed without the need for additional tools, improving operational convenience and efficiency. Whether unfolding for use or folding for storage, it can be completed quickly, saving time and effort. By connecting the first and second tube liners at both ends of the hose and providing through-holes to maintain connectivity within the internal channels, the tube core's structural stability during expansion and contraction is ensured, preventing structural damage caused by frequent expansion and contraction. The integrated design of the hose and tube liner effectively disperses stress during expansion and contraction, reducing the risk of excessive local stress on the hose, thereby helping to extend the overall service life of the tube core. This retractable tube core is not only suitable for home environments such as kitchens and bathrooms, but can also meet the needs of a variety of other applications, including industry, agriculture, and commerce, significantly enhancing its versatility and adaptability.
