AI Technical Summary

Technical Problem

Existing water purifiers have limited functions, focusing only on direct drinking water, which cannot meet the diverse water needs of users. Furthermore, the filter cartridges have low efficiency and high maintenance costs.

Method used

A water purification system was designed, comprising an inlet water path, a pre-filter cartridge, a fine filter cartridge, a post-filter cartridge, a first pure water path, and a domestic water path. It achieves the dual function of providing drinking water and domestic water through a three-stage filtration process, and outputs domestic water separately through the pre-filter cartridge, avoiding unnecessary wear and tear on the fine filter cartridge.

Benefits of technology

It expands the functional scope of the water purification system, meets the diverse water needs of users, optimizes the efficiency of filter cartridges, extends the service life of fine filter cartridges, and reduces the operation and maintenance costs of the water purification system.

Abstract

The application provides a water purification system and a water purifier. The water purification system comprises: a water inlet channel for inputting raw water; a pre-filtering filter element having a raw water inlet and a rough filtering water outlet, the raw water inlet being connected with the water inlet channel and used for rough filtering raw water output by the water inlet channel; a fine filtering filter element having a first water inlet and a first pure water outlet, the first water inlet being connected with the rough filtering water outlet and used for fine filtering rough filtering water output by the pre-filtering filter element; a post-filtering filter element having a second water inlet and a second pure water outlet, the second water inlet being connected with the first pure water outlet and used for filtering pure water output by the fine filtering filter element; a first pure water channel connected with the second pure water outlet and used for outputting pure water; and a domestic water channel connected with the rough filtering water outlet and used for outputting rough filtering water. The water purification system realizes the dual functions of direct drinking water supply and domestic water supply.
