Specific embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings, referring to Fig. 1-6：
A kind of type variable electric pump including pump case 1, is combined with spiral case 5 in pump case 1, spiral case 5 forms a pressure with pump case 1
Chamber M is connected between the water inlet 1b of pump case 1 and the water sucking mouth of spiral case 5 by inlet channel 4, the water outlet 1a connections of pump case 1
Pressure chamber M；Pump case 1 is equipped with circulation port 1c, and modular injection group is detachably combined between circulation port 1c and water inlet 1b
Part 3；The ejection assemblies 3 include water inlet extension tube 3a, circulation pipe 3b and jet pipe 3d, and the 3a cooperations of water inlet extension tube are in pump case 1
