Abstract
A faucet with pipe-in-pipe structure may include a control valve and a valve shell, and a rotating base, a sliding valve piece, and a fixing valve piece are sequentially formed inside the valve shell. The rotating base has a valve rod outwardly sticking out of the valve shell to connect to a handle. The valve rod operated by a handle can rotate the rotating base with the sliding valve piece, so that relative positions between the sliding valve piece and the fixing valve piece are controlled to operate the on/off operation of the faucet, the mixing ratios of hot water and cold water, and the amount of water flow. A valve base connected to a lower end of the valve shell is configured to prevent the fixing valve piece, the sliding valve piece and the rotating base from falling out of the valve shell.
