Who invented the drinking fountain?

Since 1998 pioneered the special water purifier for drinking fountains in the world, Ningbo Qinyuan Environmental Protection Technology Co., Ltd. has guided the healthy development of the household water purifier industry with its strong scientific and technological innovation ability, and recently launched the QSM- 1 ultrafiltration hydrophilic membrane series water purifier, which is the sixth-generation water purifier developed by Qinyuan Company using world-class water purification technology, with an aperture of 0. 1 micron, which can effectively filter bacteria and viruses. Not only can it be used with ordinary drinking fountains, but also it is convenient to clean and replace, and the price is low. The cost per liter of purified water is only 0.06 yuan, which is equivalent to a barrel of water 1.2 yuan, far lower than the price of bottled water. You can buy a state-of-the-art water purifier at the cost of drinking bottled water for one year, and bid farewell to the bottled water era.
