Description

Technical Field

[0001] This utility model relates to the field of faucets, specifically to a faucet with a water filtration and purification device. Background Technology

[0002] As we all know, although tap water undergoes sterilization and disinfection treatment after leaving the water treatment plant, it is subject to secondary pollution after passing through water pipes for many years. Tap water also contains large amounts of residual chlorine and harmful substances such as rust and scale, posing a serious threat to human health. Therefore, filtering and purifying tap water before use is crucial. However, the water pipes in newly built buildings or residential areas often lack any purification devices, leading to secondary pollution. Replacing them with faucets equipped with filters would effectively improve drinking water quality. However, currently available faucets with filters are often complex, inconvenient to replace filter cartridges, or take up a lot of space, making them inconvenient to use. Utility Model Content
