An integrated composite roll film, which is installed in a film shell, includes a roll film including a diaphragm and a hollow central pipe winding the diaphragm; wherein a central pipe has a plurality of water inlet holes cut thereon; being filtered by the diaphragm, water enters into a central pipe cavity through the water inlet hole; an inner diameter of the central pipe is matched with a pipe diameter of the roll film shell; and a filter material is installed in the cavity of the central pipe. The integrated composite roll film reduces the volume of the whole machine, increases the water outlet amount and facilitates assembly and disassembly. |
