Abstract
A faucet includes a faucet body, a control valve mounted in the faucet body and a check valve mounted in the faucet body. The faucet body is provided with a first inlet, a second inlet, an upper outlet and a lower outlet. The control valve includes a valve body, a valve shaft, a sealing gasket and a stopper. The check valve includes a valve housing, a base, a plug and an elastic member. Thus, the plug is inserted into the socket of the valve housing to isolate the check valve from the lower outlet of the faucet body, while the sealing gasket presses the peripheral wall of the flow channel to isolate the flow channel from the check valve so that the faucet has a double anti-reverse function to prevent the waste water from flowing backward into the faucet.
