AI Technical Summary

Technical Problem

In various water usage scenarios, existing water purifiers often experience frequent system startups due to water pressure differences in the low-flow water circuit module, affecting stability and efficiency.

Method used

The system employs an intelligent water distribution module. By setting a first one-way valve and a pressure reducing chamber on the low-flow water circuit module, combined with a graded filtration system of pre-filter and reverse osmosis filter, it achieves intelligent water distribution and pressure relief, avoiding frequent starts caused by excessive water pressure.

Benefits of technology

This effectively avoids the problem of frequent start-stop of low-flow water circuit modules, improves the stability and filtration efficiency of the water purifier, extends the service life of the reverse osmosis filter element, and reduces the operating cost of the system.

Abstract

This invention provides an intelligent water distribution system adapted for water purifiers, relating to the field of water purification equipment technology. The system includes a composite filter element, an intelligent water distribution module, a low-flow water distribution module, and a high-flow water distribution module. The intelligent water distribution module includes a liquid flow component, a first one-way valve, a reverse osmosis filter element, and a high-pressure switch. The liquid flow component includes a pressure-reducing chamber, a first pure water chamber, and a second pure water chamber. The first pure water chamber is connected to both the pressure-reducing chamber and the second pure water chamber. The first one-way valve allows liquid to flow exclusively from the first pure water chamber to the pressure-reducing chamber. The inlet end of the reverse osmosis filter element is connected to the outlet end of the pressure-reducing chamber. The high-pressure switch is located at the purified water outlet end of the reverse osmosis filter element. The inlet end of the first pure water chamber and the high-flow water distribution module are both connected to the high-pressure switch. The composite filter element includes a pre-filter element located at the inlet end of the pressure-reducing chamber. The low-flow water distribution module is connected to the outlet end of the second pure water chamber. This invention enables multi-scenario water use of the water system and avoids frequent startup.
