When the circulation fan 10 works, the cold air generated by the compressor 11 at the bottom of the refrigerated cabinet housing 1 will be input into the duct 9, and the duct 9 will transport this cold air to the cavity inside the top of the refrigerated cabinet housing 1. Then, this cold air will flow into the medicine refrigeration slot 7 through the L-shaped holes inside the inner support seat 5, so that the cold air can refrigerate and store the drugs and other items in the storage drawer 8; a circulation fan 10 is installed on the inner side of the bottom of the refrigerated cabinet housing 1. When the circulation fan 10 works, the cold air generated by the compressor 11 at the bottom of the refrigerated cabinet housing 1 will be input into the duct 9; a compressor 11 is also installed in the inner wall of the bottom of the refrigerated cabinet housing 1. The compressor 11 is used to cool the air inside the refrigerated cabinet, so as to be able to refrigerate and store drugs and other items.

[0034] In the embodiment of the present disclosure, as Figure 3 and Figure 7As shown, several L-shaped through holes are provided inside the inner support seat 5. Every two L-shaped through holes form a group and connect the cylindrical cavity in the middle of the inner support seat 5 with the medicine refrigeration tank 7. And one side of each group of L-shaped through holes is respectively located at the top and bottom of the inner cylindrical plate of the inner support seat 5. When the circulation fan 10 works, the cold air generated by the compressor 11 at the bottom of the refrigerator cabinet housing 1 will be input into the air duct 9, and the air duct 9 will transport this cold air to the cavity inside the top of the refrigerator cabinet housing 1. Then this cold air will flow into the medicine refrigeration tank 7 through the L-shaped holes inside the inner support seat 5. In this way, the cold air can refrigerate and store drugs and other items in the storage drawer 8. Then the cold air in the medicine refrigeration tank 7 will flow into the lower cavity between the inner circular plates of the inner support seat 5 through another L-shaped hole. After that, the cold air will continue to flow downward in the above-mentioned manner and pass through all the medicine refrigeration tanks 7.

[0035] In the embodiment of the present disclosure, as Figures 3 to 5 and Figure 7 shown, a circular plate is welded to the middle position at the top of the inner support seat 5 by six round rods, and the bottom end of the main shaft of the stepping motor 6 is connected to the circular plate at the top of the inner support seat 5. When the stepping motor 6 rotates, it can drive the inner support seat 5 to rotate by relying on the circular plate at the middle position at the top of the inner support seat 5. Moreover, the six round rods at the bottom of the circular plate will not block the upward flow of the cold air in the air duct 9 to the cavity inside the top of the refrigerator cabinet housing 1.

[0036] In the embodiment of the present disclosure, as Figures 1 to 3 and Figure 8 shown, the refrigerator cabinet housing 1 is a cylindrical housing, and a cylindrical cavity is provided inside the refrigerator cabinet housing 1. The inner support seat 5 can rotate in the cylindrical cavity inside the refrigerator cabinet housing 1. When taking and placing drugs and other items, the main control panel 4 can be used to control the stepping motor 6 to drive the inner support seat 5 to rotate. Therefore, different columns of the storage drawers 8 can be rotated to the opening at the front side of the refrigerator cabinet housing 1 for taking and placing.

[0037] In the embodiment of the present disclosure, as Figures 2 to 7 shown, an arc-shaped groove is provided on the outer side of the bottom of the medicine refrigeration tank 7. The width of the opening at the front side of the refrigerator cabinet housing 1 is twice the width of the storage drawer 8. When it is necessary to pull out the storage drawer 8, one can insert a hand into the arc-shaped groove on the outer side of the bottom of the medicine refrigeration tank 7 to pull it outwards, and the width of the opening at the front side of the refrigerator cabinet housing 1 can ensure that the storage drawer 8 can be pulled outwards.

[0038] In the embodiment of the present disclosure, as Figure 3 and Figure 7As shown, a cylindrical cavity is provided at the middle position of the inner support seat 5, and a total of five circular plates are equidistantly arranged in the cylindrical cavity. The cylindrical cavity in the middle of the inner support seat 5 enables the cold air to flow up and down repeatedly in the medicine refrigeration tank 7, so as to refrigerate and store items such as drugs in the storage drawer 8. The circular plates in the cylindrical cavity can divide the cylindrical cavity to ensure that the cold air can flow through all the medicine refrigeration tanks 7.

[0039] In the embodiment of the present disclosure, as Figure 3 and Figure 7 shown, the air duct 9 is located at the middle position of the circular plates in the cylindrical cavity inside the inner support seat 5. The top end of the air outlet pipe of the circulation fan 10 is rotatably connected to the bottom end of the air duct 9. When the circulation fan 10 works, the cold air generated by the compressor 11 at the bottom of the refrigerated cabinet housing 1 will be input into the air duct 9, and then the air duct 9 will transport this cold air to the cavity inside the top of the refrigerated cabinet housing 1, so that the cold air can flow into the medicine refrigeration tank 7. Moreover, there will be no conflict between the inner support seat 5 and the air duct 9 and the circulation fan 10 when they rotate.

[0040] Embodiment 2, on the basis of Embodiment 1, as Figures 1 to 8 shown, a cylindrical protrusion is provided at the middle position of the bottom inner wall of the refrigerated cabinet housing 1, and the outer diameter of the cylindrical protrusion is equal to the inner diameter of the cylindrical cavity in the middle of the inner support seat 5. The cylindrical protrusion at the middle position of the bottom inner wall of the refrigerated cabinet housing 1 can support the bottom of the inner support seat 5, so as to ensure the stability of the inner support seat 5 when it rotates.

[0041] Working principle of this embodiment: When installing, the refrigerator cabinet housing 1 can be placed appropriately. When it is necessary to take or place items such as drugs, the fingerprint lock panel 3 on the cabinet door 2 can be used to unlock it first, and then the cabinet door 2 can be rotated outward to open. At this time, the storage drawer 8 in the medicine refrigeration tank 7 can be pulled outwards. Moreover, after the storage drawer 8 is pulled out, the outer wall of the rear side of the storage drawer 8 will seal the outside of the medicine refrigeration tank 7, so that the cold air in the refrigerator cabinet housing 1 can be prevented from escaping outwards. Then, items such as drugs can be taken or placed. After taking or placing, the storage drawer 8 is pushed back into the medicine refrigeration tank 7 again. Labels corresponding to the drugs can also be pasted on the outside of the storage drawer 8 to facilitate the search for drugs. Moreover, when taking or placing items such as drugs, the main control panel 4 can be used to control the stepping motor 6 to drive the inner support seat 5 to rotate. Therefore, the storage drawers 8 in different columns can be rotated to the opening at the front side of the refrigerator cabinet housing 1 for taking or placing. After taking or placing, the cabinet door 2 can be closed again. During the storage process, the compressor 11 can cool the air inside the refrigerator cabinet. When the circulation fan 10 works, the cold air generated by the compressor 11 at the bottom of the refrigerator cabinet housing 1 will be input into the air duct 9, and the air duct 9 will transport this cold air to the cavity inside the top of the refrigerator cabinet housing 1. Then, this cold air will flow into the medicine refrigeration tank 7 through the L-shaped holes inside the inner support seat 5. In this way, the cold air can refrigerate and store items such as drugs in the storage drawer 8. Then, the cold air in the medicine refrigeration tank 7 will flow into the lower cavity between the circular plates on the inner side of the inner support seat 5 through another L-shaped hole. After that, the cold air will continue to flow downward in the above-mentioned manner and pass through all the medicine refrigeration tanks 7. Finally, the cold air will flow into the cavity inside the bottom of the refrigerator cabinet housing 1 to complete the cycle, so as to realize the refrigeration of items such as drugs.
