Background technique

Most of the basin faucets and kitchen faucets with the traditional mechanical opening method adopt a single water outlet method. Although some double water outlet faucets can meet the double water outlet function, there are the following problems:

(1) The traditional double waterway faucet mainly installs a water diversion valve on the faucet body and cooperates with two valve cores. The pure water does not directly enter the water pipe of pure water but passes through the water diversion valve, so the pure water will contaminated by tap water;

(2) The material with high copper content is used as the water-passing object, and the copper element of the product is easily detected as unqualified in the detection of metal pollutant precipitation, so the product does not meet the national standard GB18145-2014 and is a substandard product. There is a problem of drinking water safety in the pure water channel;

(3) Copper tubes are used for water passage inside the outlet pipe. Since the wall thickness of the copper tube is too thin, it cannot be sealed with an O-ring. It can be sealed only by welding to make it integrated. This process is complicated and has many limitations. For example, the material of the outlet elbow can only be H62 copper pipe or better material, and the cost remains high. At the same time, the R rounded corner of the outlet elbow Too large, making the appearance of the product too exaggerated and uncoordinated;

(4) The two switch operations of a general dual waterway faucet are both set at the water inlet end of the faucet body, and are not separately set, which may cause the user to misoperate when switching the waterway.
