[0010] Preferably, the spout joint and the water conduit are fixedly connected by an upper connecting piece.

[0011] The water pipe is composed of a water-passing hose, a water-passing joint and a water-passing pipe.

[0012] Preferably, the electrical component further includes a lower quick connector, an upper quick cover, an electronic housing and four fastening screws, and the four fastening screws are respectively fixed to the lower quick connector by a nut. The four corners are embedded between the two adjacent fastening screws, and the upper quick cover is disposed on the top of the four fastening screws and opposite to the lower quick connector.

[0013] As a preferred solution, the water pipe and the nozzle joint are both made of food grade plastic.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The metal curved pipe type plastic inner part zero-weight metal faucet of the invention aims to solve the common problem of the lead toxic and heavy metal precipitation in the existing faucet industry, which is a metal outer casing, and the inner water-passing component includes a water pipe, a joint, and water. Mouth, water flow power generation, magnetic valve, etc. are all food-grade plastic structural parts of the same as the water supply pipeline. The structure of the faucet of the invention is simplified, the production process is difficult, the manufacturing is convenient, and the production cost is reduced. And provide intelligent applications, water flow power generation does not require an external power supply.
