Background

Along with the continuous improvement of the living standard of people, more and more families begin to use the water purifier to improve the safety and the taste of drinking water. Currently common water purifiers include reverse osmosis water purifiers and ultra-filtration water purifiers.

The reverse osmosis water purifier has filtering precision of 0.0001-0.001 micron, and adopts reverse osmosis membrane technology, and its working principle is that certain pressure is applied to water to make water molecules and ionic mineral elements pass through the reverse osmosis membrane, so that most of inorganic salt (including heavy metal), organic matter, bacteria, virus, etc. dissolved in water can not permeate through the reverse osmosis membrane, and the permeated pure water and the concentrated water which can not permeate are strictly separated. This causes the reverse osmosis water purifier to have the following problems: 1. the effluent is too pure, and the human body drinks the reverse osmosis water all the year round, so that mineral substances in the human body are easily lost, especially calcium ions in the human body are lost, and osteoporosis is caused; 2. the water purifier adopts a multi-stage filtration mode, so that the auxiliary filter element is frequently replaced, the cost is increased, and the hidden danger of secondary pollution is easily generated; 3. the reverse osmosis water purifier needs to use a water pump, needs to be electrified, has electrical safety problems, has more joints, high water pressure, relatively higher failure rate and water leakage probability, complex structure and higher price cost.

The ultrafiltration water purifier has the filtering precision of about 0.01 to 0.1 micron, can filter silt, rust, bacteria and most viruses, has the advantages of no need of electricity, no waste water, energy conservation, environmental protection, low price, low use cost and the like compared with a reverse osmosis water purifier, and the filtered water still contains mineral substances, is mineral water and can be drunk for a long time. However, due to structural limitation, unpurified tap water is always present between the ultrafiltration membrane and the shell, which makes the content of the ultrafiltration water purifier easy to generate moss and needs to be cleaned frequently.

The existing ultrafiltration water purifier does not have a self-cleaning function, and the ultrafiltration membrane needs to be taken out after being disassembled, so that the existing ultrafiltration water purifier is very inconvenient.
