The RO water purifier comprises a normally-open solenoid valve, a manual-automatic integrated backwashing pollution discharge control system, a folding multifunctional composite filter liner filtration device, an ultrafiltration membrane filtration device, an ultraviolet sterilizer and an RO reverse osmosis filtration device, wherein a spiral inner threaded opening connected with a cylinder body is formed in an upper sealed cover of a sealed container of the RO reverse osmosis filtration device; a spiral outer threaded opening connected with the upper sealed cover is formed in an upper opening of the cylinder body; a circular clamping tube is arranged at the bottom of the sealed container; an RO reverse osmosis filter element membrane shell can be fastened by the circular clamping tube; the RO reverse osmosis filter element membrane shell is arranged at the middle part of the sealed container, an RO reverse osmosis filter element is arranged in the membrane shell, and a water production pipe is arranged at the middle part of the RO reverse osmosis filter element; a silicon rubber sealing ring is arranged at one end of the water production pipe, and a concentrated water channel is arranged at the periphery of the water production pipe; a water inlet is formed in the top of the sealed container, a water outlet is formed in the bottom of the sealed container, and a front-washing drain outlet is formed in a left side surface of the lower part of the sealed container. The RO water purifier disclosed by the invention is economical and practical.

Description

technical field [0001] The invention relates to the field of water purification equipment, especially the manufacture of drinking water purifiers for domestic use. Background technique [0002] According to the survey of relevant departments, 80% of human diseases are related to water. The main disinfection method of tap water is chlorination. Although it can remove a large number of bacteria, there are also harmful substances, especially heavy metals, chlorine molecules and nitrite in water. ingredients, while the transportation process, water tower storage, etc. will cause a certain degree of secondary pollution. Although the water is boiled, it cannot remove harmful substances such as heavy metals in the water. Excessive intake of these substances can cause great harm to the human body and threaten Some of the tap water in urban and rural areas exceeds the standard and cannot meet the "Drinking Water Hygienic Standards" of the People's Republic of China. The above-mention...
