[0035] Working principle: First, the medical staff opens the cabinet door 2 by turning it, presses the storage plate 4 to slide to the rear side, drives the storage plate 4 to squeeze the rear push rod 18, and then slides the slider 17 to the rear side, so that one end of the rotating card plate 19 is separated from the heart-shaped card slot at the top of the slider 17, and then the hook plate 24 at the bottom is rotated downward by gravity, and separated from the folding plate 15 at the bottom of the storage plate 4, and then the storage plate 4 is completely slid out from the inside of the slide 3 and disinfected separately. After the disinfection is completed, the storage plate 4 is slid back from the inside of the slide 3 to the rear side, and squeezes The top rod 18 drives the slider 17 to slide, so that the rotating card plate 19 is engaged with the heart-shaped card groove at the top of the slider 17, and the sliding groove plate 22 at the bottom slides so that the sliding column 25 is limited by the connecting strip 23, driving the hook plate 24 to rotate upward and hook with the folding plate 15 to form a fixed position. Through a simple mechanical structure, the storage plate 4 can be easily disassembled and installed, which is convenient for medical staff to disinfect the storage plate 4 separately, thereby improving the pertinence and thoroughness of disinfection, effectively reducing the residual bacteria and viruses in the refrigerator and freezer, and providing a safer environment for stored medical items.
[0036] Secondly, by turning on the switch of the ozone generator 6, ozone is emitted, which has strong oxidizing properties and can effectively kill bacteria, viruses and other microorganisms. Then, the switch of the motor 10 is turned on, and the driving end of the motor 10 rotates, driving the bottom top rod 18 to rotate, and then driving the bottom fan 9 to rotate, generating wind force, and blowing the ozone to every corner inside the cabinet 1. At the same time, the rotation of the worm 8 drives the turbine 11 to rotate, thereby driving the front connecting plate 12 to perform circular motion. The connecting plate 12 is connected to the rotating plate 13 through rotation, and the swinging motion of the entire structure is realized, which further prompts the fan 9 to blow the ozone more evenly, ensuring that every part inside the cabinet 1 can be fully exposed to ozone, greatly improving the quality and efficiency of disinfection.
