PROBLEM TO BE SOLVED: To solve a problem that the mixing efficiency of a chemical liquid by one rotor is limited.SOLUTION: In a rotary mixer in a multi-liquid mixing type injector comprising a housing 1 having a discharge nozzle 7 at a lower part, one drive rotor 3 located in a space part 2 within the housing 1 and driven rotors 4, 4 disposed in parallel with the drive rotor 3,: the through hole 5 of the drive shaft S of a head part is formed at the upper part of the housing 1; the top edge of the drive rotor 3 is connected to the lower end of the drive shaft S; and a mixed liquid can be agitated and mixed with a plurality of rotors 3, 4, 4 by forming the injection ports 6, 6a of a chemical liquid to the space part 2 at the upper side of the housing 1. |
