Description

A water regulating device

technical field

The utility model relates to the field of water treatment, in particular to a water volume regulating device.

Background technique

Water tap is the popular appellation of water valve, is used for controlling the size switch of water flow, and water tap is installed in every household. As water pollution becomes more and more serious, people need more reliable water quality to protect their health. Therefore, many families will install filters on the faucets, and filter the tap water through the filters before using them. In existing faucets, the filter screen is generally installed at the water outlet of the faucet, and using the existing faucet to filter tap water has the following disadvantages:
