Description

Technical Field

[0001] This utility model belongs to the technical field of water treatment equipment, and in particular relates to an integrated water purifier. Background Technology

[0002] In industrial raw water purification systems, filtration devices are the core components. To improve the efficiency of raw water purification, multiple filtration devices are often installed in a raw water purification system. These multiple filtration devices are often connected in series by pipes. Although this improves the efficiency of raw water purification, it makes the purification system structure too large and complex.

[0003] For example, patent document with publication number "CN220900033U" discloses a split-type reverse osmosis pipeline structure for seawater purification, relating to the field of water purification technology. It includes a fixed frame, with a first and second mounting rod rotatably mounted on the top of the inner wall of the fixed frame via an adjustment assembly. An installation assembly is located between the first and second mounting rods, comprising several first reverse osmosis pipeline bodies and several second reverse osmosis pipeline bodies. This patented technology increases the assembly error redundancy between the mounting block and the shock absorber by setting a connecting block, making the purification system easier to assemble. However, because this purification system uses multiple pipelines to connect multiple filtration devices in series, although it improves the raw water purification efficiency, it makes the entire purification system structure too large and complex.
