However, this structure makes the main body of the faucet difficult to mold and the material cost is extremely high. Therefore, this utility model provides an assembled plastic water channel structure that can solve the above-mentioned technical problems. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model proposes a plastic water channel structure for faucets.
[0004] A faucet plastic water circuit structure includes a main body, a valve core seat, a water inlet core, and a fixing component.
