Background technique

A household water purifier is a water purification device that purifies tap water. Existing household water purifiers have a single function and generally only have one or several stages of ultrafiltration treatment. Although the water quality can meet the general needs, the taste is not good. Moreover, after the existing household water purifier is generally connected to a faucet, it is difficult to meet the water demand of the whole house.

In addition, usually the water purifiers on the market are difficult to meet the water demand of the whole house. Usually, a pre-filter is used as a primary filter product, and then a water purifier is used as drinking water for making tea, etc., plus a Ultrafiltration membrane products are used to purify domestic water such as laundry or washing, which leads to occupying space and is troublesome in management, maintenance and installation. However, the existing central water purifiers on the market simply only purify, have no disinfection function, and cannot meet the standard for direct drinking. Moreover, the existing water purifier using RO reverse osmosis has a small water volume, which is difficult to meet the water demand of the whole house.

In addition, the water purifiers on the existing market are often unusable during power outages and cannot obtain purified water, so they are greatly limited during power outages.
