Direct drinking machine is a kind of equipment that provides direct drinking water. It purifies tap water by ultrafiltration membrane separation technology, and retains minerals in the water while filtering impurities, providing people with direct drinking water rich in minerals, and the effluent is healthy and safe.
Water purifier is a kind of pure water produced by filtering raw water (physical method) through reverse osmosis without adding any compounds, which is popular in the world at present.

Working principle of water purifier
The first level: Microfiltration membrane: Microfiltration membrane removes all kinds of visible objects/dust and impurities from tap water. These particles come from pipeline aging, rust, secondary pollution of roof water tank and so on.
Second stage: compressed carbon: compressed carbon removes chlorine and organic impurities, such as harmful pesticides. It can also absorb the odor, color and smell produced by organic matter in water, which come from disinfection by-products of tap water.
The third stage: ultrafiltration membrane: ultrafiltration membrane can remove bacteria, viruses and spores from water.
The fourth stage: filter life indicator: the device adopts gear structure design. With the passage of water, the rotation of the gear makes an inner shaft move upward until the water outlet is blocked and the water cannot pass through, that is, the total amount of water passing through the water purifier is calculated through the designed stroke, thus ensuring the safety of the water outlet.
