The rotation motor 327 drives the steering worm 314 to rotate. The steering worm 314 matches with the steering worm gear 305 to drive the central shaft 313 to rotate. The central shaft 313 drives the rotation base 304 to rotate, thereby providing power for the adjustment of the material picking and placing position; A sealing ring matching the inner wall of the cabinet 100 is provided on the outer side of the lower end of the rotation base 304, improving the sealing effect between the rotation base 304 and the cabinet 100; The movable door group includes opening door chutes 102 symmetrically arranged on the outer side of the cabinet 100. A movable door 200 is slidably fitted in the opening door chutes 102. The movable door 200 is made of a transparent material. The movable door 200 is connected to an opening door driving member for driving its combination or separation. The opening door driving member includes a displacement cavity 205 provided inside the cabinet 100. A transmission connecting rod 204 is slidably arranged in the displacement cavity 205. A threaded block 203 is provided at the end of the transmission connecting rod 204. The threaded block 203 is threadedly arranged on an opening screw rod 202. One end of the opening screw rod 202 is rotatably connected to the inner wall of the cabinet 100. The other end of the opening screw rod 202 is fixedly connected to the output end of an opening door motor 201. The opening door motor 201 is installed on the inner wall of the cabinet 100. Threaded areas corresponding to the two threaded blocks 203 are provided on the opening screw rod 202. The helix directions of the two threaded areas are opposite. Driven by the opening door motor 201, the opening screw rod 202 cooperates with the threaded block 203 to drive the two threaded blocks 203 to approach or move away from each other. In this way, combined with the transmission of the transmission connecting rod 204, the two movable doors 200 are driven to open and close; The door opening seal includes a sealing chute 331 provided at the lower end of the sealing top plate 328. A sealing pressure block 317 is slidably provided in the sealing chute 331. The lower end of the sealing pressure block 317 matches the upper end of the drying area 326 to achieve sealing. The upper end of the sealing pressure block 317 is connected to the inner wall of the sealing chute 331 through a return spring. The upper through hole of the sealing chute 331 communicates with the lower end of the inflatable sealing tube 210. The upper end of the inflatable sealing tube 210 passes through the upper partition plate 309 and communicates with the sealing air cylinder 206. A piston block 209 is slidably provided inside the sealing air cylinder 206. The piston block 209 is connected to the inner bottom of the sealing air cylinder 206 through a return spring. An outer end of the piston block 209 is provided with a piston pull rod 208. An outer end of the piston pull rod 208 is provided with a traction rod. The end of the traction rod is connected to the transmission link 204 through an elastic cord 207. When the transmission link 204 drives the movable door 200 to open the door, the transmission link 204 will pull the piston pull rod 208 to move through the elastic cord 207. The piston pull rod 208 drives the piston block 209 to compress the air inside the sealing air cylinder 206, so as to send the gas along the inflatable sealing tube 210 into the sealing chute 331. The sealing pressure block 317 in the sealing chute 331 will be pressed down, and the sealing pressure block 317 will seal the upper end of the drying area 326. At this time, the position of the sealed drying area 326 is actually isolated from the inner cavity of the cabinet body 100, so that taking materials will not cause a large amount of external air to enter and break the internal drying environment. On the contrary, when the transmission link 204 drives the movable door 200 to close the door, under the action of the return spring, the piston block 209 returns to its original position. At this time, the sealing pressure block 317 will leave from the upper end of the drying area 326 to avoid affecting the rotation of the rotating base 304; A caching component for caching instruments is further provided on the cabinet body 100. The caching component includes a caching port 103 provided on the lower side of the cabinet body 100. A drawer box 104 is cooperatively provided in the caching port 103. A drawer pull ring 105 is provided on the outer side of the drawer box 104. A partition plate 107 is arranged inside the drawer box 104. The partition plate 107 divides the inner cavity of the drawer box 104 into two storage areas 106, so as to cache medical instruments for temporarily storing the dried instruments; Working principle: In actual use, first control the rotation driving part to work through the control panel, so that the drying area 326 outside the rotating base 304 without load stays at the loading and unloading port 101 position. Then open the movable door group, and the door opening seal is triggered. When the transmission connecting rod 204 drives the movable door 200 to open, the transmission connecting rod 204 will pull the piston pull rod 208 to move through the elastic rope 207. The piston pull rod 208 drives the piston block 209 to squeeze the air inside the sealing air cylinder 206, so as to send the gas along the inflatable sealing pipe 210 into the sealing chute 331. The sealing pressure block 317 in the sealing chute 331 will be pressed down, and the sealing pressure block 317 will block the upper end of the drying area 326. At this time, the position of the blocked drying area 326 is actually isolated from the inner cavity of the cabinet body 100; Then just put the instrument to be dried into the support outer disc 324. First, perform a preliminary disinfection operation on the instrument through the disinfection component, and then close the movable door group. At this time, the door opening seal will be cancelled. Drive the rotating base 304 to rotate through the rotation driving part, and perform drying treatment by heating the instrument and ultraviolet disinfection. At the same time, suck the air in the drying area away through the negative pressure pump 311, so as to construct a negative pressure environment, which is helpful for the rapid drying of the instrument. When the rotating base 304 rotates, the instrument will complete revolution and rotation along with the placing rack group, which is helpful for the rapid drying of the instrument.
