The other end of the baffle 4 is engaged with the card slot 10, which plays a limiting role on the dissolving tank 3 placed inside the limiting plate 9.

[0050] Then, the medicine is placed inside the dissolution tank 3, and water is added to dissolve the medicine. Then, the switch of the motor 51 is turned on, and the motor 51 drives the transmission shaft 54 ​​to rotate. When the transmission shaft 54 ​​rotates, it drives the stirring teeth 53 to rotate. The medicine inside the dissolution tank 3 can be stirred under the rotation of the stirring teeth 53, thereby accelerating the dissolution rate.

[0051] If it is necessary to adjust the height of the motor 51, loosen the connecting piece 7, then press against the motor 51, and then change the position relationship of the sleeve 6 on the outer surface of the lifting rod 1. When the height adjustment of the motor 51 is completed, pass the connecting piece 7 through the sleeve 6 and screw it with the connecting hole 8 inside the lifting rod 1, thereby completing the height adjustment of the motor 51.
