Abstract: Traditional reverse osmosis (RO) water purifiers generally consist of five step filter units, which have many series of filter elements, occupy space, different life and inconvenient replacement. In addition, filter bottles, water valves, pressure switches and other water-related components are basically connected through water pipes, with many leakage points, inconvenient production and maintenance, and high cost. The shortcomings of the traditional water purifier, it is necessary to introduce a new integrated design of filter element and waterway plate. Through the new integrated design of water purifier, the performance and reliability of water purifier are further improved, user feel is better, and product upgrade is promoted.

Key words: Reverse osmosis (RO) water purifier, Integrated filter, Integrated waterway plate
