AI Technical Summary

Technical Problem

Existing concealed shower systems with pre-installed boxes cannot flexibly add water outlets, requiring consumers to remove and re-lay pipes when their needs are upgraded, thus limiting functional expansion.

Method used

A bypass clearance groove is added inside the box cavity of the pre-embedded box assembly, and a bypass water outlet is set on the side of the pre-embedded core. The water outlet is added by adapting to the water valve body with different bypass water outlets. The hot-melt outer pipe and positioning inner pipe structure are used for sealing connection, simplifying the installation process.

Benefits of technology

Water outlets can be added without dismantling the walls, simplifying the installation process, improving sealing reliability, reducing operational difficulty, lowering manufacturing costs, and enhancing water system reliability.
