[0024] Three self-adjusting components 4 are respectively arranged above the three medicine storage boxes 3. The self-adjusting components 4 are used to adjust the storage space according to the capacity of the medicine. After a part of the medicine is used, the amount of medicine is reduced, and the self-adjusting component 4 will drop according to the reduction in the amount of medicine, so that the air on the top surface of the medicine and the medicine remain isolated, avoiding certain medicines (especially those containing unsaturated bonds or easily oxidized components) from undergoing oxidation reactions when contacting with oxygen in the air, resulting in degradation of the effective ingredients of the medicine, thereby reducing its efficacy. In addition, it can also avoid moisture in the air being absorbed by certain medicines, causing the medicine to agglomerate, change in solubility or change in chemical properties, and avoid volatilization of the medicine to change the concentration and effect of the medicine. The self-adjusting component 4 includes a screw cap shell 41 threadedly connected to the top of the medicine storage box 3, and an air hole 5 is opened on the top of the screw cap shell 41. A filter screen 6 is screwed on the thread above the screw cap shell 41, and the air hole 5 is used to balance the medicine storage The air pressure inside the box 3 prevents the partition 45 from being obstructed in movement due to pressure difference. A first annular telescopic shell 42 slides inside the screw-on cover shell 41, a second annular telescopic shell 43 slides inside the first annular telescopic shell 42, and an annular telescopic plate 44 slides inside the second annular telescopic shell 43. Two sliding grooves are provided on the inner wall of the screw-on cover shell 41, the inner wall of the first annular telescopic shell 42 and the inner wall of the second annular telescopic shell 43. Two sliders are fixed on the outer side of the first annular telescopic shell 42, the outer side of the second annular telescopic shell 43 and the outer side of the annular telescopic plate 44, and the sliders slide in the corresponding sliding grooves respectively. A partition 45 is provided below the annular telescopic plate 44, and the partition 45 presses on the medicine to seal the medicine and isolate the medicine from contact with the air. A plurality of assist springs 46 are provided above the partition 45, and the plurality of assist springs 46 are used to help the partition 45 to be tightly pressed against the upper surface of the medicine.

[0025] A plurality of first positioning ring covers 47 are fixed above the inner wall of the rotary cover shell 41, and a second positioning ring cover 48 is fixed above the partition 45. The number of the first positioning ring covers 47 and the second positioning ring covers 48 is the same and corresponds to each other up and down. The number of the two is the same as that of the assist spring 46. The first positioning ring cover 47 and the second positioning ring cover 48 respectively limit the two ends of the assist spring 46. The partition 45 includes a fixed plate 49, a rotating plate 410 and an internal threaded ring 411. The second positioning ring cover 48 is fixed on the fixed plate 49. The rotating plate 410 rotates on the outside of the fixed plate 49, and a sealing ring is fixed on the outside of the rotating plate 410 to increase the sealing of the partition 45 and the medicine storage box 3. The internal threaded ring 411 is fixed on the top of the rotating plate 410, and the internal threaded ring 411 is threadedly screwed to the bottom of the annular telescopic plate 44.

[0026] To enable those skilled in the art to fully understand the technical solution, this application provides the following overall overview:

[0027] When in use, put the medicine into the medicine storage box 3, screw the screw cover shell 41 on the medicine storage box 3 to seal the medicine storage box 3. According to the height of the medicine at this time, the partition 45 will be pressed above the medicine under the thrust of the assist spring 46 and its own gravity to isolate the medicine from the air. When the medicine is reduced after use, the height of the medicine will drop, and the partition 45 will move downward under the thrust of the assist spring 46, and drive the annular telescopic plate 44 to slide down. According to the downward distance, the annular telescopic plate 44, the first annular telescopic shell 42 and the second annular telescopic shell 43 will slide down. 3 will be pulled out as needed, maintaining the connection between the screw cap shell 41 and the partition 45. The position of the partition 45 can be automatically changed according to the reduction of the medicine volume, so that the medicine can always remain in a sealed state in the medicine storage box 3, slowing down the medicine oxidation reaction caused by the contact between air and medicine, and maintaining the stability and effectiveness of the medicine. For medicines containing volatile components, reducing the air space can reduce the volatilization loss of these components, maintain the concentration of the medicine, and prevent moisture in the air from being absorbed by certain medicines, resulting in medicine agglomeration, solubility changes, or changes in chemical properties.

[0028] The booster spring 46 will show elastic fatigue and aging after long-term use. After the booster spring 46 is fatigued, the internal threaded ring 411 and the annular telescopic plate 44 can be detached by rotating the rotating plate 410, so that the partition 45 can be removed and the booster spring 46 can be exposed. One end of the new booster spring 46 is placed into the first positioning ring cover 47, and then the second positioning ring cover 48 on the partition 45 is respectively inserted into the other end of each booster spring 46, and the rotating plate 410 is rotated until the internal threaded ring 411 and the annular telescopic plate 44 are screwed together. The booster spring 46 is replaced conveniently and can be replaced regularly to prevent the elastic fatigue of the booster spring 46 from affecting the downward movement of the partition 45, thereby reducing the effect of isolating the contact between air and medicine.
