It also includes: A loading drawer assembly, a plurality of loading drawer assemblies are longitudinally distributed and installed on the inner side of the sterilizing cabinet body 2 corresponding to the inlet and outlet 17, and two adjacent loading drawer assemblies are slidably connected; a telescopic assembly for driving the bottom loading drawer assembly to move is also fixed on the sterilizing cabinet body 2, and a guide rail assembly for slidingly supporting the top loading drawer assembly is also installed in the sterilizing cabinet body 2; when the telescopic assembly drives the bottom loading drawer assembly to extend out of the sterilizing cabinet body 2, the remaining loading drawer assemblies extend out in sequence with the bottom loading drawer assembly and are finally distributed in a stepped manner; An upper sealed flow-balancing component is installed on the inner upper part of the sterilizing cabinet body 2, which is capable of sealing the uppermost loading drawer component. An exhaust component corresponding to the upper sealed flow-balancing component is also installed on the top of the sterilizing cabinet body 2. The upper sealed flow-balancing component is used to evenly discharge the air in the loading drawer component, and the exhaust component is used to assist in extracting excess air in the loading drawer component. A lower sealed pulsating steam exhaust component is installed at the lower inner side of the sterilizing cabinet body 2, which is capable of sealing the lowermost loading drawer component. The lower sealed pulsating steam exhaust component is also used to control the pulsating upward discharge of steam; A high-temperature steam component is installed on the outside of the sterilization cabinet body 2, and the high-temperature steam component is connected to the lower sealed pulsating steam exhaust component. The high-temperature steam component is used to control the delivery of high-temperature steam to the lower sealed pulsating steam exhaust component.

[0026] In the embodiment of the present invention, after the material to be sterilized is placed in the loading drawer assembly 2, the telescopic assembly drives the lowest loading drawer assembly to retract into the sterilization cabinet body 2, and the remaining loading drawer assemblies are successively retracted and finally completely placed in the sterilization cabinet body 2. The sealing door assembly is then closed to seal the inlet and outlet 17. The vacuum pump 18 is started to extract as much air as possible from the inner cavity of the sterilization cabinet body 2 to create conditions for the next sterilization step.

[0027] Next, the upper sealing flow-distributing assembly seals the uppermost drawer assembly, while the lower sealing pulsating steam exhaust assembly is responsible for sealing the lowermost drawer assembly. The high-temperature steam assembly starts to operate, and the lower sealing pulsating steam exhaust assembly controls the delivery of high-temperature steam into the system. Since the multiple drawer assemblies remain sealed and interconnected, the steam directly acts on the material without entering the inner cavity of the sterilizer cabinet 2, achieving an efficient steam sterilization effect.

The arc-shaped telescopic cylinder 11 adopts an arc-shaped structure, and the center of the arc-shaped telescopic cylinder 11 is located on the axis of the hinge shaft between the sealing door 12 and the sterilization cabinet body 2. When the arc-shaped telescopic cylinder 11 is extended, the sealing door 12 can abut against the sealing ring 16, and the sealing door 12 can completely seal the inlet and outlet 17, thereby realizing an automated opening and closing door structure, avoiding burns, and having high reliability.

When all the placement drawers 13 are retracted into the sterilization cabinet body 2, the inner cavities of the multiple placement drawers 13 are in a sealed and connected state, ensuring the reliability of sterilization.

[0031] A limiting member is also provided between two adjacent loading drawer assemblies, and the limiting member includes a slider 20 and a supporting ball 21.
