[0039] In the storage state, the temperature measuring assembly 30 can be clamped on the side of the shell 10.

[0040] In the working state, the temperature measuring assembly 30 is exposed to the shell 10.

[0041] In the embodiment, when temperature measurement is needed to be performed by the temperature measurement assembly 30, the temperature measurement assembly 30 can be adjusted from the storage state to the working state to expose the temperature measurement assembly 30, and then temperature measurement can be performed. After the temperature measurement is completed, the temperature measurement assembly 30 can be adjusted back to the storage state, and the temperature measurement assembly 30 is clamped to the side of the shell 10 to be stored, thereby improving the convenience of the high-precision rapid temperature measurement device.

[0042] Please refer to Figure 3 The shell 10 includes a rear shell 12 and a front shell 11 detachably mounted on the rear shell 12. The front shell 11 and the rear shell 12 enclose a receiving cavity 13. The display and control assembly 20 is arranged in the receiving cavity 13. The power supply component 40 is arranged on the side of the rear shell 12 away from the front side. In the embodiment, the front shell 11 and the rear shell 12 can be detachably connected by means of bolt connection, buckle connection or the like, so as to facilitate subsequent disassembly and maintenance of internal parts.

[0043] The end of the shell 10 and the side are provided with a cavity 14 for accommodating the temperature measurement assembly 30.

The temperature measurement is performed by the thermocouple wire at the end of the second end. The measured temperature can be transmitted to the display and control assembly 20 through the wire arranged in the probe part 32 and displayed on the display and control assembly 20.

[0045] Specifically, the display and control assembly 20 includes a control circuit board 21 and a display screen 22 mounted on the control circuit board 21.

[0054] The voltage output end outputs 2.4V reference voltage, the thermistor NTC samples to make environmental temperature compensation, and the second resistor R2 is used as the voltage dividing resistor of the thermistor NTC.

[0055] The first capacitor C1 is used for stabilizing the reference voltage output by the voltage output end.

[0056] The third resistor R3 and the fourth resistor R4 form a voltage dividing resistor, divide the reference voltage, and supply the base voltage of the negative end of the thermocouple 33.

[0057] The second capacitor C2 is used for stabilizing the voltage dividing voltage of the third resistor R3 and the fourth resistor R4.

[0058] The first resistor R1 supplies the base voltage of the positive end of the thermocouple 33.
