Description

Technical Field

[0001] The utility model relates to the field of bathroom faucet accessories, in particular to a faucet water distribution core. Background Art

[0002] Existing shower faucets are generally divided into one-piece and split combination types. The one-piece type is produced by sand casting and other processes. Its material is generally brass, so the cost is relatively high. Then, the corresponding valve core installation position needs to be drilled on its main body, so the production is more troublesome. The split type generally uses brass for its water channel and is installed in the shower faucet belly shell by a combination installation method. Although it can reduce a lot of weight compared with the traditional one-piece type, it requires complicated processes to process the various sealing surfaces after the sand casting is completed, and the installation and fixation of the valve core is also more troublesome.
