Description

technical field [0001] The invention relates to the technical field of faucets, in particular to a reverse-proof faucet. Background technique [0002] With the continuous improvement of living standards, people's requirements for drinking water are also increasing. Household water purifiers have also become commonly used small household appliances. The purified water produced by the water purifier usually flows out through a water tap after passing through a section of water pipe. And the pipeline in the faucet on the market is all connected with the water purifier for a long time at present, and during the non-use period, the water pipe between the water purifier and the faucet and the space in the faucet are all filled with water, and contact with air. This can easily nourish bacteria and cause secondary pollution of water sources. Therefore, there is a need in the art for a faucet that is isolated from the outside world during non-use periods.
