Description

Technical Field

[0001] The invention relates to the field of shower faucets, and in particular to a shower faucet body. Background Art

[0002] Existing shower faucets are generally solid metal structures, and the water channels are processed by sand casting or drilling. They have problems such as heavy overall weight, high material cost, and complex production process. At the same time, the water channel from the hot water inlet to the mixing valve core is in direct contact with high-temperature hot water, and the temperature will be transmitted to the outer wall through the shell, which can easily cause burns to users when they touch it during use.

[0003] In response to the above problems, the applicant applied for a shower faucet body with application number CN202520687220.X on April 12, 2025. During the subsequent production process, the applicant found that after the pre-assembly of the accessories at both ends of the shell, the pipes had cantilever end position accuracy errors caused by bending or shrinkage after welding. After being assembled to the shell and welded to the shell, it is often difficult to align the pipes (position correction is required). When there are many pipes (many water outlets), each pipe needs to be aligned, which seriously affects the production efficiency, and it is easy to have inaccurate circumferential positioning during assembly; at the same time, the temperature control and gear switching are located at both ends of the main body, which brings certain restrictions to the appearance design and use control.
