[0030] In one embodiment of the utility model, the top end face of the support rod 1 is fixedly connected to a rotating motor 4, the output end of the rotating motor 4 is fixedly connected to a rotating rod 5, the end of the rotating rod 5 away from the rotating motor 4 passes through the bottle stopper 2, the support rod 1 is hollow, the axis of the support rod 1 coincides with the axis of the rotating rod 5, the outer wall of the rotating rod 5 does not contact the inner wall of the support rod 1, the end of the rotating rod 5 away from the rotating motor 4 is fixedly connected to a trapezoidal block 6, the side wall of the rotating rod 5 is fixedly connected to a mounting frame 7, the bottom end face of the mounting frame 7 is fixedly connected to a vertical rod 8, the side wall of the vertical rod 8 is sleeved with a sleeve 9, the side wall of the sleeve 9 is fixedly connected to a stirring plate 10, and the number of stirring plates 10 is set. Several groups of stirring plates 10 are staggeredly distributed on the side wall of the sleeve 9. In the longitudinal direction, the edges of every two groups of stirring plates 10 are chamfered. When the stirring plates 10 are pushed by the liquid, the chamfers interrupt the stratification of the liquid and promote the mixing of the liquid. The side wall of the support rod 1 is sleeved with a heat sink 12, and the heat sink 12 is sleeved with an injection tube 13. The bottom end surface of the injection tube 13 is fixedly connected with an injection needle 14. The end of the injection needle 14 away from the injection tube 13 is sleeved with the bottle stopper 2. The injection tube 13 is movably connected with the injection push rod 15. The side wall of the support rod 1 is fixedly connected with an insulation plug 11, and the insulation plug 11 is sleeved with a calorimeter, so that the temperature in the calorimeter and the injection tube 13 remains stable.

When liquid is injected into the ampoule bottle 3, the air inside the ampoule bottle 3 is discharged through the ventilation tube 16, so that the air pressure in the ampoule bottle 3 remains stable.

[0032] The linear motor 17 drives the transmission block 18 and the injection push rod 15 to move downward, and then pushes the liquid in the injection tube 13 into the ampoule bottle 3 through the injection needle 14. The four injectors can mix different types of liquids at the same time, and each liquid can be controlled separately.

The stirring plate 10 moves relative to the liquid, and the liquid drives the stirring plate 10 to rotate around the vertical rod 8, so that a small vortex appears in the liquid near the stirring plate 10. Furthermore, the edges of each two groups of stirring plates 10 in the longitudinal direction of the stirring plate 10 are chamfered. When the stirring plate 10 is pushed by the liquid, the chamfer interrupts the stratification of the liquid.

[0037] Four injectors mix large doses of the same liquid, and four synchronous injections are achieved through the push rod synchronization disk 19, and the same liquid is injected into the mixing container evenly and simultaneously. This helps to enhance the mixing effect of the liquid, ensure that different parts of the liquid can fully contact and mix, and improve the uniformity and consistency of the mixing.
