The inner wall of the upper bevel gear 8 is fixedly connected to the central shaft 11. The inner wall of the top end of the liquid dispensing tank 1 is rotatably connected to the hollow tube 10. The inner wall of the hollow tube 10 is rotatably connected to the central shaft 11. The inner wall of the upper bevel gear 8 is fixedly connected to the outer wall 11 of the top end of the central shaft. The inner wall of the lower bevel gear 9 is fixedly connected to the outer wall of the hollow tube 10. The upper and lower bevel gears rotate in opposite directions to drive the hollow tube 10 and the central shaft 11 to rotate in opposite directions. The outer walls of the hollow tube 10 and the central shaft 11 are fixedly connected to the guide rod 12. The outer wall of the guide rod 12 is slidably connected to the stirring mechanism 13. The upper and lower stirring mechanisms 13 rotate and stir in opposite directions under the drive of the hollow tube 10 and the central shaft 11, thereby improving the liquid dispensing efficiency.

[0030] Reference Figure 1-Figure 3The outer wall of the central axis 11 is slidably connected with an adjusting rod 17, and the outer wall of the adjusting rod 17 is rotatably connected with two groups of rotating sleeves 15. The outer wall of the rotating sleeve 15 is hinged with two groups of brackets 16, and the end of the bracket 16 is hinged with the bottom of the stirring mechanism 13. When the stirring mechanism 13 rotates, the bracket 16 drives the rotating sleeve 15 to rotate together. When the rotating sleeve 15 moves in the vertical direction, the angle of the bracket 16 will change, thereby pushing the stirring mechanism 13 to move to both ends. The outer wall of the stirring mechanism 13 is fixedly connected with a cleaning mechanism 14. When the stirring mechanism 13 moves outward, it will drive the cleaning mechanism 14 to move outward together until it fits with the inner wall of the liquid dispensing tank 1. At this time, starting the stirring mechanism 13 again can make the cleaning mechanism 14 clean the inner wall of the liquid dispensing tank 1. The bottom end of the liquid dispensing tank 1 is rotatably connected with a ring 18, and the inner wall of the ring 18 is slidably connected to the outer wall of the adjusting rod 17. The inner wall of the ring 18 is elastically connected with a reset spring 19. The buckle assembly includes a limit block 20, one end of a return spring 19 is fixedly connected to the back of the limit block 20, and the other end of the return spring 19 is fixedly connected to the inner wall of the ring 18. The limit block 20 can squeeze the return spring 19 to move outward. At the same time, the elastic force generated by the deformation of the return spring 19 gives the limit block 20 an outward thrust to reset it. The outer wall of the adjusting rod 17 is provided with a plurality of groups of limit grooves 22. The outer wall of the limit block 20 is engaged with the inner wall of the limit groove 22. After the limit block 20 is inserted into the limit groove 22, the position of the adjusting rod 17 is fixed, so that the position of the stirring mechanism 13 and the cleaning mechanism 14 is fixed. A pull rod 21 is fixedly connected to the back of the limit block 20, and the back of the buckle assembly is fixedly connected to the inner end of the pull rod 21. Pulling the pull rod 21 outward can drive the limit block 20 to move outward and release the engagement with the limit groove 22. The outer wall of the pull rod 21 is slidably connected to the inner wall of the ring 18.

[0031] Working principle: the raw material is put into the liquid preparation tank 1 through the liquid inlet 2, and then the motor 5 is driven to make the main bevel gear 7 drive the upper bevel gear 8 and the lower bevel gear 9 to rotate, thereby driving the central shaft 11 and the hollow tube 10 to rotate, thereby driving the upper and lower two sets of stirring mechanisms 13 to rotate in opposite directions to improve the liquid preparation efficiency, and then the prepared liquid is discharged from the liquid outlet 3. When the inner wall of the liquid preparation tank 1 is cleaned, the pull rod 21 is pulled outward until the limit block 20 and the limit groove 22 are released, and the adjusting rod 17 is pushed upward to move the rotating sleeve 15 in the vertical direction, so that the angle of the bracket 16 is offset, and the stirring mechanism 13 is pushed to move to both ends together with the cleaning mechanism 14 to fit the inner wall of the liquid preparation tank 1. Then, when the motor 5 is started this time, the cleaning mechanism 14 can clean the inner wall of the liquid preparation tank 1.
