In the spray pump, because the cutter group 45 is positioned at the sewage inlet side of the cutter disc 44, when the cutter group 45 rotates at a high speed (the rotating speed is generally more than 2000n/min), various types of dregs flowing into the sewage suction port 43 can be stirred, including lumpy dregs and long-strip fibers, and meanwhile, the cutter group 45 is matched with the cutter disc 44 to work, so that the size of the dregs is cut to be smaller than the minimum through passage of the spray pump and a pipeline, and the cut dregs and excrement sewage can be continuously pumped under the negative pressure action of the centrifugal rotor 42, thereby ensuring that the spray pump and the pipeline can continuously and normally work without blockage, reducing the difficulty of cleaning and maintenance, and the use cost, and being suitable for large-scale popularization and use; the structure of the cutter set outside and inside the cutter head can fully stir and cut the dregs flowing to the dirt suction port 43, especially has very obvious stirring and cutting effects on the agglomerated dregs, prevents the phenomenon that fibers wind the centrifugal rotor 42, and the cutter set 45 can cut long fibers with any length to avoid the phenomenon that the fibers wind the centrifugal rotor.
