[0002] Anti-freezing components are often arranged inside faucets, showers or other water outlet devices, which can prevent the water inside these products from freezing and expanding in volume and then cracking the internal pipelines. At present, the anti-freezing components on the market generally adopt the structure of telescopic pistons. When installing, it is often necessary to additionally set an opening in the above internal pipeline and install an additional installation pipe at this opening to accommodate the above piston. This anti-freezing structure not only increases the size of the product, but also this type of installation structure needs to be independently designed, developed and assembled for each product, resulting in high development costs of the product. In addition, the above anti-freezing components have low independence and cannot be flexibly applied or adapted to each water outlet product. Summary of the Invention

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0033] Please refer to Figures 1 to 6 , an internally installed modular anti-freezing component, which is installed inside the water pipeline and includes an elastic change cavity 21. When the water inside the water pipeline freezes and expands in volume, the change cavity 21 of the anti-freezing component can be compressed under the action of external force, creating more space for water and ice, thereby preventing the water pipeline from being frozen and cracked.

[0034] In this embodiment, an elastic member 1 for pushing the variable chamber 21 to expand and recover is provided inside the variable chamber 21, so that after the ice thaws, the variable chamber 21 can automatically return to its initial state to cope with the next icing situation. Preferably, the elastic member 1 is a compressed spring, which has a simple structure and is easy to replace. An existing one can be directly purchased.

[0035] Based on the above embodiment, in one embodiment, the anti-freezing component includes a housing 2 and a plug 3. The variable chamber 21 is arranged inside the housing 2. The plug 3 closes the variable chamber 21 and is movably installed relative to the housing 2 to realize the compressibility of the variable chamber 21, and the elastic member 1 can push the plug 3 to reset.

[0036] For easier placement inside the water pipeline, in one embodiment, the housing 2 is tubular, and an opening of the variable chamber 21 is provided at one end. The plug 3 is telescopically installed in the opening. Additionally, in other embodiments, openings and plugs 3 are provided at both ends of the variable chamber 21, so that the variable chamber 21 has a larger compression space.

[0037] To prevent water from entering the variable chamber 21 and causing the anti-freezing function to fail, a sealing structure is provided between the plug 3 and the housing 2. Preferably, the sealing structure is an annular sealing rib 31 or a sealing ring provided on the circumferential portion of the plug 3.

[0038] To further increase the compression space of the variable chamber 21, the housing 2 is made of a soft rubber material. Under the action of an external force, the housing 2 itself can also compress the variable chamber 21 by deforming, thereby further improving the anti-freezing effect.

[0039] In one embodiment, radially extending support ribs 32 are provided on the outer circumference of the head of the plug 3 extending to the outside of the housing 2. During installation, the ends of the support ribs 32 closely adhere to the inner wall of the water pipeline, which can prevent the anti-freezing component from shaking under the impact of water flow. The gaps between the support ribs 32 provide a flow channel for the water flow to avoid blockage inside the water pipeline.

[0040] The anti-freezing component provided by the present utility model is an in-built type. During use, it can be directly installed inside the water pipeline without the need to additionally open a docking port outside the water pipeline and dock with an installation cavity, which reduces the forming difficulty of the water pipeline. Additionally, the independent components provided by the present utility model are applicable to various water pipelines inside, with a wide range of applications. They can enable various existing products to directly have the anti-freezing function without the need to redesign the structure, and have strong practicability and are easy to promote.
