[0002] A water purifier is a water treatment device that deeply filters and purifies water according to the user's water usage requirements. Its technical core is the filter membrane in the filter element device. Currently, the main technologies come from three types: ultrafiltration membrane, RO reverse osmosis membrane and nanofiltration membrane.

[0003] Existing water purifiers usually use multi-stage filter elements to filter and purify water, but the multi-stage filter elements are installed vertically in a water filter box. During installation, the filter element needs to be tilted at a certain angle to be connected to the same water circuit board. In addition, complex pipelines are also provided on the outside of the water filter box. These pipelines are connected to the multi-stage filter element through the water circuit board, which makes it difficult to disassemble and assemble the filter element and inconvenient to replace it.
