Particularly, in the application, the resistor layer is divided into a plurality of independent temperature measuring areas, namely, the projections of any two temperature measuring areas on the bearing plate 102 are not overlapped, so that the temperature value or the temperature change value in each temperature measuring area can be determined by acquiring information of the resistor wires filled in each temperature measuring area, and the position accuracy of temperature detection on the bearing plate 102 is greatly improved.
It should be emphasized that, in the present application, the position of the fan 108 is limited, in the running process of the device, the fan 108 is generally required to run, so that the heating wire coil or other electronic components are cooled, however, in the running process of the fan 108, the fan inevitably blows to the resistor layer, so that the temperature detected by the resistor layer is different from the temperature in the actual bearing area 1022, and generally is lower than the actual temperature, so that the accuracy of the detection is greatly deviated.

The resistance wire is a temperature-sensitive material, and when the temperature changes, the resistance value of the resistance wire also changes.
In a specific embodiment, the coverage of the wind deflector 104 is limited, so that the projection of the wind deflector on the carrier plate 102 is limited to cover the resistance layer completely, thereby ensuring that the fan 108 cannot blow to the resistance layer during operation, and improving the accuracy of temperature detection of each temperature measurement area by the resistance layer.
