The invention discloses a self-cleaning device for a range hood oil net, an oil net module with the same and a range hood. The self-cleaning device comprises a bracket module provided with a fluid channel inside, and a rotating module rotationally arranged on the bracket module; the rotating module includes a spraying pipe communicated with the fluid channel; the spraying pipe is provided with a driving spraying hole and a washing spraying hole; and when the driving spraying hole sprays a fluid, the rotating module is driven to rotate around a rotating center shaft. According to the self-cleaning device for the range hood oil net, the driving spraying hole is formed in the spraying pipe for rotating the rotating module to realize rotary spraying and washing of the oil net, so that the cleaning coverage area can be enlarged, no cleaning blind area exists, the cleaning effect is good, and the cleaning efficiency is high.
