AI Technical Summary

Technical Problem

The existing detachable filter cartridge structure is complicated to disassemble when removing the composite filter cartridge, especially since it requires disassembly in steps, which makes it inconvenient for users to replace it.

Method used

The design incorporates a filter bottle, a composite filter element assembly, and a connecting handle. The filter bottle has an internal cavity, and the composite filter element assembly is housed within the cavity. Water filtration is achieved through an inlet and outlet structure. The combination of a pre-filter, a post-filter, and a central tube allows for easy assembly and disassembly, as well as water path separation. The connecting handle is detachably connected to the connector, simplifying the disassembly process.

Benefits of technology

It achieves convenient disassembly and assembly, water circuit separation and dual filtration, improves filtration effect, reduces maintenance difficulty and enhances system reliability, and simplifies the disassembly and replacement steps of composite filter element components.
