[0037] A through hole is provided at the bottom of the rotating shaft 7, the top end of the fixed rod 10 is rotatably connected to the axial position of the top of the rotating shaft 7, the bottom end of the fixed rod 10 passes through the through hole and is fixedly connected to the bottom inner wall of the outer shell 1, and the outer wall of the fixed rod 10 is fixedly connected to the first bevel gear 11.

[0038] A penetrating rotating hole is opened at one end of the first stirring blade 8 near the rotating shaft 7, and the rotating hole extends to the inner wall of the rotating shaft 7. The sliding seat 13 is rotatably connected to the inner wall of the rotating hole, and the adjusting rod 14 is slidably connected to the inner wall of the sliding seat 13. The sliding seat 13 is fixedly connected to the axial position of one end near the fixed rod 10 with a second bevel gear 12 that meshes with the first bevel gear 11.

[0039] like Figure 5 As shown, the inner wall of the sliding seat 13 is provided with a plurality of circumferentially arranged limiting grooves 18, and the outer wall of the adjusting rod 14 close to one end of the sliding seat 13 is fixedly connected with a plurality of circumferentially arranged limiting guide rails 19, which are slidably connected to the inner wall of the limiting groove 18.

[0040] When stirring and mixing is required, the servo motor 6 drives the rotating shaft 7 and the first stirring blade 8 thereon to rotate, and the internal solution is rotated and stirred. At this time, there is relative rotation between the sliding seat 13 that rotates with the first stirring blade 8 and the fixed rod 10 fixed on the outer shell 1, and the sliding seat 13 can be driven to rotate by the first bevel gear 11 and the second bevel gear 12 that are meshed with each other.

This process is repeated, and the adjusting rod 14 and the second stirring blade 9 thereon can be driven to reciprocate in the horizontal direction.

[0045] Through the sliding part, the second stirring blade 9 can move back and forth in the horizontal direction to expand the area of ​​solution stirring, further improve the heating efficiency of the solution, and can move back and forth with the solution to avoid stratification of the solution with stirring in the same direction, affecting the mixing efficiency and the heating efficiency of the solution.
