[0013] The utility model will be further explained below in conjunction with the drawings of the specification.

[0014] As Figs. 1 to 3The powder medicine dispensing device comprises a cylindrical box body 2, a box cover 1 matched with the box body 2 and a switch mechanism 3. The box body 2 comprises a barrel 21 and a plurality of partitions arranged in the barrel. The partitions comprise a top partition 24, a bottom partition 22 and a plurality of intermediate partitions 23. The space between adjacent intermediate partitions 23 forms a middle storage space, the space between the bottom partition 22 and the intermediate partitions 23 forms a bottom storage space, and the space above the top partition 24 forms a top storage space. In this embodiment, two intermediate partitions 23 are arranged, and four storage spaces are arranged in total. A first through hole 25 is arranged on the bottom partition 22, and a second through hole 26 is arranged on each of the intermediate partitions 23 and the top partition 24. The positions of the second through holes 26 are corresponding, and the first through hole 25 and the second through hole 26 are arranged staggeredly. The first through hole 25 and the second through hole 26 are both fan-shaped, and the area of each of the first through hole 25 and the second through hole 26 accounts for one fourth of the area of the partition. The lower end of the barrel 21 extends downward and forms a groove at the bottom of the box body 2, and the bottom partition 22 is spaced apart from the lower end of the box body 2 by a distance. The switch mechanism 3 comprises a rotating shaft 33 arranged in the middle of the barrel 21 and penetrating through the top partition 24, the intermediate partitions 23 and the bottom partition 22, and a plurality of baffles arranged on the rotating shaft 33. The baffles correspond to the partitions one by one, and are tightly attached to the bottom of the partitions. The baffles comprise a first baffle 31 for shielding the first through hole 25 and a second baffle 32 for shielding the second through hole 26. The first baffle 31 and the second baffle 32 are arranged staggeredly. The first baffle 31 is arranged in the groove, and the box body 2 can stand stably without affecting the movement of the first baffle 31. The bottom of the bottom partition 22 is provided with a first stop block 33 for limiting the closing stroke of the first baffle 31 on the first through hole 25 and a second stop block 34 for limiting the opening stroke of the first baffle 31 on the first through hole 25.
