Integrated waterway board, filtering assembly and water purifier

The utility model relates to an integrated waterway board, a filter assembly and a water purifier. The integrated waterway board comprises a bracket; the filtering pipeline assembly is arranged on the bracket; the pure water pipeline assembly is arranged on the bracket, and the pure water pipeline assembly is communicated with the outflow end of the filtering pipeline assembly; the first valve is arranged on the pure water pipeline assembly and used for connecting or disconnecting the pure water pipeline assembly; the wastewater pipeline is arranged on the bracket and is communicated with the outflow end of the filtering pipeline assembly; and the second valve is arranged on the wastewater pipeline and is used for connecting or disconnecting the wastewater pipeline. According to the technical scheme, the technical problems that water channels in a traditional water purifier are disordered, assembling is difficult, and the occupied space is large are effectively solved. 本公开涉及一种集成水路板、过滤组件及净水机，该集成水路板包括：支架；过滤管道组件
