A second channel transporting second liquid is formed between the first pipe and the second pipe. A connecting sleeve is hollow and is mounted around a front end of the first pipe. A valve core is mounted on a front end of the connecting sleeve, and having a center hole centrally and axially formed through the valve core and multiple water outlets formed in a periphery of the valve core and communicating with the second pipe. The inlet water pipes gathers two different waterways in one inlet pipe and allow easy connection with faucet, and ensures good hermetic seal.
