Moreover, the second jet structure 11 can be connected or disconnected with the air intake structure 16 by only moving the transfer vehicle 6, which has the effect of convenient operation.

[0049] In some embodiments of the present application, the second jet structure 11 includes a plurality of second jet pipes 12 equidistantly fixed at the middle of the placement frame 7 , and the second jet pipe 12 is provided with a plurality of jet hole groups 13 equidistantly distributed along its length direction.

[0051] All the connecting pipelines 14 can simultaneously press against the air intake structure 16 and communicate with the air intake structure 16 .

[0052] In this embodiment, by setting up a plurality of equidistantly distributed second jet tubes 12, and each jet tube is provided with a plurality of equidistantly distributed jet hole groups 13, high-temperature steam can be evenly sprayed toward the middle position of the placement frame 7, that is, the high-temperature steam can be evenly dispersed in the middle position of the placement frame 7, thereby improving the sterilization effect.

[0053] In order to further improve the effect of uniform steam spraying. In some embodiments of the present application, the jet hole group 13 is composed of a plurality of jet holes distributed in an annular shape;

[0054] The gas jet holes of two adjacent gas jet hole groups 13 are distributed in a staggered manner.

[0055] In some embodiments of the present application, the air intake structure 16 includes a box 17 fixed inside the sterilization tank 1, and the box 17 is connected to the first jet structure 8 and the steam generating device 4. Specifically, the box 17 is arranged at the right end of the sterilization tank 1, the first jet pipe 9 is connected to the box 17, and the box 17 is connected to the steam generating device 4 through the gas pipeline 5.

[0056] One end of the box body 17 is provided with through holes 18 , which are equal in number to the connecting pipes 14 and correspond one to one.

[0057] The connecting pipe 14 is a T-shaped structure. The horizontal section of the connecting pipe 14 is connected to the second injection pipe 12. The vertical section of the connecting pipe 14 can press against the outer wall of the box body 17 and communicate with the corresponding through hole 18 and be concentric, thereby realizing the docking work between the second injection structure 11 and the air intake structure 16.

[0058] Furthermore, the inner diameter of the vertical section of the connecting pipe 14 is greater than the diameter of the through hole 18 .

[0059] In order to improve the sealing effect after the vertical end of the connecting pipe 14 is connected to the through hole 18 , in some embodiments of the present application, a rubber pad 15 is fixed to the contact end of the connecting pipe 14 and the box body 17 .

[0060] In some embodiments of the present application, the driving device 19 includes an internal threaded sleeve 20, which is distributed along the length direction of the guide rail 3.

One end of the screw 21 is rotatably connected to a push plate 22 through a bearing, and the other end of the screw 21 is fixed with a handle 23.

[0061] The internal thread sleeve 20 passes through the tank door of the sterilization tank 1 and is sealed and fixedly connected with the tank door.

[0062] During use, after the placement plate enters the sterilization tank 1, the sealing cover 2 is closed, and then the handle 23 is turned. The handle 23 drives the screw 21 to rotate, and the screw 21 rotates and drives the push plate 22 to move. When the push plate 22 contacts the corresponding placement frame 7, the push plate 22 pushes the placement frame 7 to move. At this time, the transfer cart 6 and all the placement frames 7 move synchronously. When the vertical section of the connecting pipeline 14 is pressed against the box body 17 and connected with the corresponding through hole 18, the rotation of the handle 23 is stopped. At this time, the push plate 22 presses the corresponding placement frame 7, that is, the transfer cart 6 is limited, and then the steam generating device 4 can be started to perform steam sterilization.
