TECHNICAL FILED
[0001] The present disclosure relates to the technical field of faucets, more particularly to a faucet structure for a washbasin.
BACKGROUND
[0002] Washbasin faucets are water outlet apparatus installed on washbasins. Conventional washbasin faucets in the market typically use all-copper materials. However, copper materials are expensive, and often result in excessive heavy metal precipitation. Therefore, structures that employ plastic components for water passage, with a metal shell (the shell material can be plastic, zinc alloy, aluminum alloy, etc.) which reduce costs, and with plastic components for water passage and a non-water-passing shell they prevent issues such as exceeding the standard for nickel metal in electroplated parts or exceeding the lead content in copper materials.
