[0049] Please refer to Figure 3 and Figure 4 In some implementations of this embodiment, a pressure sensor 10 for sensing the food to be flipped is provided on the flipping table 405 , and the pressure sensor 10 is electrically connected to the control panel 9 .

[0050] In this embodiment, the pressure sensor 10 is disposed on the '|' part of the turnover table 405. When the pressure sensor 10 detects pressure, the drive rod 407 drives the turnover table 405 to rotate, thereby realizing the turnover of the块状 food, greatly improving its use effect.

[0051] During use, the conveying mechanism 2 is started through the control panel 9, and the conveyor belt 202 of the conveying mechanism 2 rotates. The food to be disinfected is placed at one end of the conveyor belt 202. After the food enters the sterilization box 301, the side and top surfaces are continuously irradiated by ultraviolet rays. When the food to be disinfected is conveyed to the position of the turnover table 405, the food presses the pressure sensor 10 through the conveying and extrusion of the conveyor belt 202. The drive rod 407 drives the sliding table 404 to move, and the movement of the sliding table 404带动 the connecting rod 406 to pull the turnover table 405. The bottom surface of the food on the turnover table 405 is turned to the side to be irradiated by ultraviolet rays, and after gradually separating from the turnover table 405 through the action of the conveyor belt 202, it can be output.

[0052] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application.
