Fig. 11 and 12 schematically show the state of each part of the medicine dropping device of the medicine bottle shown in fig. 9 in the workflow.

Referring to fig. 11 and 12, in step S1, when the upper cover plate 302, the upper dial 306 and the positioning body 309 of the lower dial 307 are overlapped, the particle-type preparation in the bottle body fills up the two input receiving grooves 3021 of the upper cover plate 302 due to gravity. At this time, the input receiving groove 3021 of the upper cover 302 is not communicated with the transfer groove 3041 of the outer turntable 304.

In step S2, the lower dial 307 rotates counterclockwise to drive the inner dial 303 to rotate counterclockwise; at the same time, the upper dial 306 rotates counterclockwise, which drives the outer dial 304 to rotate counterclockwise. The striker plate 3031 forms a fan-shaped relay space 3042 with a variable angle with the front edge of the relay groove 3041 (the front edge when the relay groove 3041 rotates counterclockwise). The striker plate 3031 of the inner rotary disc 303 rotates to the side near the input receiving groove 3021 and stops, the front edge of the intermediate groove 3041 rotates to the lower side of the input receiving groove 3021 of the upper cover plate 302, and at this time, the fan-shaped intermediate space 3042 is located below the input receiving groove 3021 of the upper cover plate 302.

In step S3, the upper dial 306 rotates clockwise to rotate the outer dial 304 clockwise; meanwhile, the lower dial 307 rotates clockwise, which drives the inner dial 303 to rotate clockwise. The upper dial 306 and the lower dial 307 rotate to the input containing groove 3021 of the upper cover plate 302 and the transfer groove 3041 of the outer dial 304, the fan-shaped transfer space 3042 is communicated with the medicine leakage port 3051 of the lower cover plate, and the granular preparation in the fan-shaped transfer space 3042 leaks out through the medicine leakage port 3051, thereby completing the output of the granular preparation once.

The upper cover plate 302, the upper dial 306 and the lower dial 307 can be reset under the magnetic force of the magnet, and the positions of the positioning bodies 309 of the upper cover plate 302, the upper dial 306 and the lower dial 307 are overlapped to wait for the next output of the particle-type preparation.

The positions of the upper dial 306 and the lower dial 307 when the rotation stops, that is, the included angle between the striker plate 3031 and the front edge of the transit groove 3041 at this time, determine the mass of the output granular preparation. The particle-type preparation with corresponding quality can be output by respectively driving the upper dial 306 and the lower dial 307 to rotate to a certain angle through gear transmission according to the quality of the particle-type preparation to be output.
