Description

A small household capacitor deionized water purifier

technical field

The invention relates to a water purifier, in particular to a small household capacitor deionized water purifier.

Background technique

At present, household water purifiers have been popularized to a certain extent in China. Although there are many types of household water purifiers on the market, they are basically based on membrane water purification, including: microfiltration, nanofiltration, ultrafiltration, and reverse osmosis membrane methods. Among them, microfiltration and nanofiltration technologies are mostly used as pretreatment methods for water purification equipment; ultrafiltration technology is currently the most widely used water purification technology in China; reverse osmosis membrane method is mostly used in high-end water purifiers. Although the membrane water purifier has a good water purification effect, the filter element will be polluted and blocked by groceries in the water during use, and the water purification effect will be significantly reduced; moreover, the filter element needs to be replaced regularly, which increases the use cost ; In addition, because membrane equipment requires high water inlet pressure when working, this type of water inlet needs to be installed with a booster pump to increase the water inlet pressure, which increases the complexity of the equipment and the consumption of electric energy.
