[0028] Through the design of the level 16 , the level 16 transmits the position of the cover plate 2 to the controller 14 .

[0029] Specifically, the upper end of the movable plate 10 is fixedly connected with a guide rod 11, and the guide rod 11 is slidably connected with the cover plate 2.

[0030] Through the design of the guide rod 11 , when the movable disk 10 moves, the guide rod 11 guides the movable disk 10 to prevent the movable disk 10 from rotating.

[0031] In this embodiment, a sealing ring 12 is in contact with the outer side of the movable plate 10 , the sealing ring 12 is in contact with the sterilizer body 1 , and the sealing ring 12 is fixedly connected to the cover plate 2 .

[0032] Through the design of the sealing ring 12, the sealing ring 12 seals the connection between the cover plate 2 and the sterilizer body 1, and through cooperation with the movable plate 10, the sealing effect is more sufficient.

[0033] On the other hand, fixing bolts 17 are provided inside the rotating disk 15 , and the fixing bolts 17 are in contact with the cover plate 2 .

The first magnetic block 7 is rotated, and the second magnetic block 8 rotates with the first magnetic block 7, and the screw 9 rotates with the second magnetic block 8. A threaded motion occurs between the screw 9 and the second magnetic block 8, driving the movable disk 10 to move downward, and the movable disk 10 squeezes the sealing ring 12. The connection between the sealing ring 12 and the sterilizer body 1 is tighter, and a better sealing effect is achieved. The connection method of the power component adopts a magnetic connection, which avoids the need for common connection methods. A hole needs to be opened on the cover plate 2, which affects the sealing of the cover plate 2. At the same time, the first magnetic block 7 is limited by the limit plate 6 to prevent the device from loosening during use and affecting the sealing of the device. When the movable disk 10 moves, the guide rod 11 guides the movable disk 10 to prevent the movable disk 10 from rotating. At the same time, the rotating disk 15 is rotated to adjust the angle of the level 16 to prevent the level 16 from tilting due to uneven ground, which affects the use of the level 16. The level 16 is adjusted to a horizontal position and fixed with the fixing bolts 17. The sterilizer body 1 is sterilized. When the sterilization is completed, hold the handle 18 and the detection plate 20, squeeze the pressure sensor 19, and the pressure sensor 19 transmits the signal to the controller 14. The controller 14 controls the electromagnetic block 21 to cut off the power, so that the handle 18 can be pulled up conveniently, the cover plate 2 can be opened, and the items inside can be taken out.
