Description
Technical field
The present invention is related with water treatment field, and in particular in terms of water purifier.
Technical background
Currently, barrelled water drinker is very universal at home, but due to there is the replacement because sending water, empty bucket,
" secondary pollution " phenomenon caused by bottled water drinking-water overlong time three aspect factor and since reservation is visited and brought not
Just and security risk, making barrel water drinking machine, gradually the water purifier similar in specification replaces.Although the water technology of water purifier
Varied, essence is constant, is all to remove impurity in tap water, for the purpose of bacterium using municipal tap water as raw water, pure
Water purification water principle is identical as bottled water.It may be said that reverse osmosis water purifier is the barreled water production device of scaled down version.With substance
The continuous extension of improvement of living standard and personalization market, people are more and more deeper to health and the concern and subdivision of commodity, instead
The pattern that can meet pure water requirement and commodity that infiltration this small-sized existing system of water purifier is now drunk increasingly are used widely.So
And with the popularization of reverse osmosis water purifier, also gradually it is exposed in the restricted problem of application aspect, i.e. reverse osmosis purified water
Machine needs water source, power supply, is typically only capable to be placed near the water source of kitchen.Municipal tap water pipeline not only difficulty but also influence beauty are reequiped,
Result in use inconvenience and it is sorry, to seriously affect the popularization of household drink water apparatus direct from unboiled water.The defect and insufficient serious shadow
It has rung the universal of reverse osmosis water purifier and has improved.
