[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a high-precision temperature sensor with the following advantages:

[0015] 1. This high-precision temperature sensor, through its protective components, can effectively isolate dust, dirt, and other tiny particles from the external environment. If these particles adhere to the temperature sensor, they may cause measurement errors and affect the accuracy of the data.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] This embodiment is a high-precision temperature sensor.

[0024] like Figure 1-4As shown, the device includes a junction box 1, an extension tube 2 fixedly installed on the lower outer surface of the junction box 1, a protective tube 3 fixedly installed on the lower outer surface of the extension tube 2, a wire 6 installed inside the protective tube 3, a temperature sensing element 7 connected to the lower end of the wire 6, the temperature sensing element 7 being located at the bottom of the inner cavity of the protective tube 3, a protective assembly 4 installed on the lower outer wall of the protective tube 3, the protective assembly 4 including a first fixing block 8 and a protective cover 9, an opening and closing structure 5 provided between the protective cover 9 and the protective tube 3, the opening and closing structure 5 including a second fixing block 10, an electric telescopic rod 11, a mounting block 12, a connecting rod 13 and a connecting block 14, the first fixing block 8 being fixedly installed on the lower outer wall of the protective tube 3.

[0025] The protective cover 9 covers the bottom of the protective tube 3; one end of the second fixing block 10 is fixed to the outer wall of the upper part of the protective tube 3; the upper outer surface of the electric telescopic rod 11 is fixedly connected to the lower outer surface of the second fixing block 10 away from the protective tube 3; the lower outer surface of the piston rod in the electric telescopic rod 11 is between the upper outer surface of the mounting block 12; the connecting rod 13 is fixedly installed on the lower outer surface of the mounting block 12; the connecting block 14 is fixedly installed between the lower part of one side of the outer surface of the connecting rod 13 and one side of the outer surface of the protective cover 9.

[0026] It should be noted that this utility model is a high-precision temperature sensor. The junction box 1, extension tube 2, protective tube 3, wire 6, and temperature sensing element 7 described herein are all prior art. The temperature sensing element 7 is located at the bottom of the inner cavity of the protective tube 3, which is readily known to those skilled in the art and will not be elaborated further. The protective component 4 and the opening and closing structure 5 are as shown in the appendix to the specification. Figure 1 As shown, at this time, the protective cover 9 in the protective assembly 4 covers the outer wall of the lower end of the protective tube 3, protecting the area where the temperature sensing element 7 is located, preventing dust from adhering to the outer wall of the lower part of the protective tube 3, keeping the outer wall of the lower end of the protective tube 3 clean, reducing errors, and improving measurement accuracy. When it is necessary to detect and measure the temperature, the operation of the electric telescopic rod 11 in the opening and closing structure 5 drives the mounting block 12, connecting rod 13 and connecting block 14 to descend. The connecting block 14 drives the protective cover 9 to descend. Opening the protective cover 9 can quickly expose the temperature sensor to the measured environment, thereby quickly responding and accurately measuring the current temperature. This not only ensures effective protection of the sensor under normal circumstances, but also enables rapid temperature measurement when needed, improving measurement efficiency.
