The display control module 4 includes a display screen 8, a main control chip U3, and a power supply module. The display screen is mounted at the first mounting position, and the display screen and the power supply module are respectively connected to and controlled by the main control chip U3. The second mounting position 14 includes a socket mounting hole 104. The socket assembly 2 is at least partially inserted into the socket mounting hole 104, and the portion of the socket assembly 2 located within the socket mounting hole 104 forms locking grooves on opposite sides, such that the locking portions on opposite sides of the socket mounting hole 104 are respectively embedded into the locking grooves to fix the socket assembly. The socket assembly 2 is connected to and controlled by the main control chip. The connector of the data cable on the food temperature detection probe is electrically connected to the socket assembly 2.

[0042] Specifically, the panel structure 1 includes a panel body 11 and two edge members 12. Both sides of the panel structure 1 are provided with folded edges 101, each folded edge 101 having a plurality of mounting holes 102. Each edge member 12 has mounting posts 103 corresponding to the mounting holes 102. The mounting holes 102 and mounting posts 103 are fixedly connected by bolts 3, so that the two edge members 12 are arranged opposite to each other and detachably connected to both sides of the panel body 11. At least one of the two edge members 12 has a socket mounting hole 104.

The socket assembly 2 includes an assembly shell 21 and a probe socket body 22. The probe socket body 22 is fixedly connected to the inner wall of the assembly shell 21. The assembly shell 21 is inserted into the socket assembly hole 104. The assembly shell 21 is connected to the socket assembly hole 104 by elastic buckle strips 202 on both sides, which can achieve easy installation. The limiting plate 201 of the assembly shell 21 can cover the socket assembly hole 104 to prevent dust and oil stains from entering and ensure the sealing and hygiene of the socket assembly 2. When it is necessary to maintain or replace the probe socket body 22, simply remove the panel structure 1 and operate the elastic buckle strips 202 to easily remove the socket assembly 2. This avoids the cumbersome and safety hazards of the traditional bolt fixing method and effectively prevents the socket assembly 2 from being damaged or lost due to improper operation.
