Description

Technical Field

[0001] The utility model belongs to the technical field of water purification and filtration, and specifically relates to a water purification filter. Background Art

[0002] The antibacterial ultrafiltration water purifier is a component of water purification equipment. It uses ultrafiltration membrane technology to effectively filter out tiny impurities in the water. At the same time, it is equipped with an antibacterial coating to inhibit, sterilize and ultrafilter the water. This type of water purifier is widely used in shopping malls, industrial parks, hospitals, schools and many other places.

[0003] However, in actual use, this type of water purifier product usually directly connects the water inlet pipe and the filter barrel, without any components between the two to reduce the impact pressure of the water body. Sometimes, the connection may become disconnected or the water impact pressure is high, resulting in leakage. At the same time, the number of filter barrels installed cannot be adjusted according to the actual water pressure and water consumption, and branching and graded adjustable zoning water purification is not possible, resulting in poor water conservation effect. When replacing or cleaning the filter barrels, all of them need to be replaced or cleaned at once, and branching or graded replacement and cleaning of the filter barrels is not possible, resulting in high cost of use. To this end, we have proposed a water purifier that can reduce the impact pressure of the water body and has branching or graded zoning water purification functions. Utility Model Content
