[0002] A water pipe is a pipeline for supplying water. In modern decoration, water pipes are all constructed in a wall-embedded manner. There are three categories of water pipes. The first category is metal sleeves, such as hot-dip cast iron pipes with internal plastic coating, copper pipes, stainless steel pipes, etc. The second category is plastic-coated metal sleeves, such as plastic-coated steel pipes, aluminum-plastic composite pipes, etc. The third category is plastic pipes, such as PB, PP-R, etc.

[0003] For the water inlet pipe used outdoors, it is very easy to freeze in winter at low temperatures. Once the water pipe freezes, it will be unable to be used normally at worst, and at best, the water pipe will be damaged. In the prior art, heat preservation materials are used to wrap the outer wall of the water pipe to avoid the freezing problem of the water pipe, but the joints at both ends of the water pipe cannot be well heat-insulated and anti-frozen, making the water pipe easy to freeze at the joints. Therefore, the utility model provides a water inlet pipe with an anti-freezing function to solve the deficiencies in the prior art. Summary of the Utility Model
