Description

Technical Field

[0001] The present application relates to the technical field of water purification equipment, and in particular to a household ultrafiltration water purification equipment. Background Art

[0002] Water is the source of all things. People cannot live without water. Polluted water can cause various parasitic diseases and other diseases after being absorbed by the human body. Water purification equipment is a kind of equipment that produces purified water. It can remove particles, bacteria, viruses and other microorganisms in the water to improve the water quality.

[0003] At present, the household ultrafiltration water purifiers available on the market all have stainless steel shell structures. When cleaning the membrane fibers, the shell needs to be disassembled, and the membrane fibers need to be taken out of the shell for cleaning. Such household ultrafiltration water purifiers are generally used for filtering tap water or rainwater. However, the turbidity of pond water in mountainous areas is relatively high. When the water consumption is relatively large, the sludge in the water will quickly clog the surface of the membrane fibers. Users may need to clean the membrane fibers once a day. It is very inconvenient to frequently disassemble the shell to take out the membrane fibers for cleaning. At the same time, the ultrafiltration water purifier with such stainless steel shell structure is troublesome to disassemble and assemble, and frequent disassembly and assembly will affect the sealing of the shell, thereby reducing the water quality and shortening the service life of the equipment.
