The rectangular plates 21, in multiple sets, are provided on one side of which is a drive unit for raising and lowering the lifting plate 19. The drive unit includes a first rack 22, a first gear 23, and a first servo motor 24. A positioning assembly is also provided, including a lifting box 25 and a lifting block 26. A lifting unit for raising and lowering the lifting block 26 is provided inside the cavity of the lifting box 25. The lifting unit includes a rotating shaft 29, a second gear 30, and a second rack 27. Rotation of the second gear 30 causes the second rack 27 and the lifting block 26 to rise and fall synchronously. Multiple sets of baffles 18 are evenly spaced.

[0027] A pure steam sterilizer includes a cabinet body 10 and the sealing structure described above. A rectangular groove is provided at the front end of the cabinet body 10.

One side of the side door 11 is movably connected to the rectangular groove by a hinge. The limiting component is installed in the corresponding second mounting groove, and the locking component is installed in the corresponding first mounting groove.

[0028] Specifically, this application sets a hinge to connect the side door 11 to the cabinet 10. A sealing plate 15 is fixedly connected to one side of the side door 11. A rubber sealing gasket 16 is set on the outer wall of the sealing plate 15 to play a sealing role. In order to prevent the side door 11 from moving and causing air leakage during operation, a limiting component and a locking component are set to tightly fix the side door 11 to the cabinet 10, thereby effectively improving the sealing performance and sealing effect of the device. The operation is simple and convenient.

[0029] The second mounting slot has recessed holes at both the top and bottom, through which a guide cylinder 20 moves. The end of the guide cylinder 20 away from the recessed hole is fixedly connected to the lifting plate 19. A first rack 22 is fixedly connected to one side of the lifting plate 19, and a first gear 23 is movably meshed with the first rack 22. A first servo motor 24 is fixedly installed inside the cabinet 10 cavity, and the output shaft of the first servo motor 24 is fixedly connected to the first gear 23.

After the lifting block 26 moves to its end, it engages movably with the corresponding latch 17. A first switch 13 is provided on the outer wall of the cabinet 10, and the first switch 13 is electrically connected to the second servo motor 28.

[0032] Specifically, by setting one end of the lifting block 26 to movably pass through the lifting box 25, and the second rack 27 is fixedly connected to one end of the lifting block 26 inside the cavity of the lifting box 25, the operator controls the switch of the second servo motor 28 through the first switch 13. The second servo motor 28 drives the rotating shaft 29 to rotate. The rotating shaft 29 is fixedly passed through the second gear 30. The second gear 30 is movably meshed with the second rack 27, so that the rotation of the second gear 30 drives the second rack 27 and the lifting block 26 to rise and fall synchronously. By setting a loop guide frame 31 fixedly installed on the lifting block 26, and the rotating shaft 29 movably passing through the loop guide frame 31, the stability of the lifting block 26 during the lifting process is improved.
