[0026] A stirring component 2, wherein the stirring component 2 is located inside the mixing tank 1 and stirs and mixes the raw materials and ingredients added inside the mixing tank 1 to allow them to react fully;

[0027] The reciprocating component 3 is connected to the stirring component 2. When the stirring component 2 stirs the raw materials in the mixing tank 1, the reciprocating component 3 performs reciprocating motion in the vertical direction in the mixing tank 1 to improve the mixing effect of the raw materials and the ingredients.

[0028] The stirring assembly 2 includes a motor 20, which is fixedly connected to the outer surface of the upper end of the mixing tank 1. The output end of the motor 20 is fixedly connected to a stirring rod 21. The annular outer surface of the stirring rod 21 is fixedly connected to a gear 1 22. The annular outer surface of the gear 1 22 is meshed with a gear 24. The annular outer surface of the gear 2 24 is meshed with a gear ring 23.

The lower end of the gear 2 24 is provided with a sub-rod 31 for further stirring the raw materials. The motor 20 drives the stirring rod 21 to rotate to stir the raw materials inside the mixing tank 1. The gear 1 22 drives the gear 2 24 to rotate, and cooperates with the sub-rod 31 to further increase the stirring effect. At the same time, under the action of the gear ring 23, the gear 2 24 and the sub-rod 31 make circular motion with the gear 1 22 as the center.

[0029] The diameter of the gear 1 22 is smaller than the diameter of the gear 2 24 .

[0030] The outer surface of the lower end of the gear ring 23 is fixedly connected with a retaining ring 26, the outer surface of the lower end of the gear 1 22 is fixedly connected with a baffle 25, and the gear 2 24 is located at the upper end of the retaining ring 26 and the baffle 25, and the retaining ring 26 cooperates with the baffle 25 to increase the stability of the gear 2 24.

The spring 35 pulls the sub-rod 31 along the main rod 30 with a tendency to pull upward. When the gear 24 makes a circular motion, the thimble 34 contacts the wave groove 32. The cooperation of the two makes the sub-rod 31 fluctuate up and down while rotating, thereby further stirring the original liquid inside the mixing tank 1.

[0032] A through groove 37 is provided on the outer surface of the upper end of the auxiliary rod 31, and a one-way valve 38 is fixedly connected to the inside of the through groove 37. An exhaust hole 39 is provided on the outer surface of the auxiliary rod 31, and a one-way valve 1 36 is fixedly connected to the annular outer surface of the main rod 30.
