Technical Field

[0001] The utility model relates to the technical field of temperature sensors, in particular to a temperature sensor. Background Art

[0002] With the development of society, temperature sensors are increasingly used in various fields. A temperature sensor is a device that measures temperature and converts the temperature signal into an electrical signal or other easily processable signal output. Temperature sensors play a vital role in many fields, including industrial production, scientific research, medical care, and environmental monitoring.

[0003] Existing temperature sensors typically use thermistors to measure temperature. A thermistor is a resistor element that is highly sensitive to temperature changes, with its resistance value varying significantly with temperature. By measuring the resistance of a thermistor, the temperature of the object being measured can be determined. Thermistors are widely used in temperature sensors due to their high sensitivity, fast response, compact size, and low cost.

[0004] However, existing temperature sensors present a significant problem. Thermistors are typically sealed within the device, making them difficult to repair or replace if damaged. This is because, in many cases, to ensure measurement accuracy and stability, the thermistor is enclosed in a sealed structure that is difficult to disassemble. Damage to the thermistor requires replacing the entire temperature sensor, which not only increases costs but can also lead to extended equipment downtime and compromise production efficiency. Summary of the Invention

[0025] Thermistor 4 is sensitive to temperature changes, and its resistance value changes accordingly when the temperature changes. The resistance change signal of thermistor 4 is transmitted through power line 3. When installing metal shield 5, metal shield 5 is aligned with cylindrical mounting block 2 and pressed downward. The inner wall of metal shield 5 squeezes block 603, causing block 603 to compress first spring 602 and slide into mounting slot 601. When metal shield 5 is fully installed, block 603 is ejected by first spring 602 and snaps into slot 604, thereby securing metal shield 5 to cylindrical mounting block 2. When thermistor 4 needs to be repaired or replaced, block 603 is pushed out of slot 604, allowing metal shield 5 to be removed for repair or replacement.

[0026] The rear end of the clamping block 603 is fixedly connected to the first spring 602 , and the rear end of the first spring 602 is fixedly connected to the inner wall of the mounting groove 601 .

[0027] When installing the metal shield 5, the first spring 602 is compressed, providing an outward elastic force to the clamping block 603, allowing the clamping block 603 to be locked into the clamping slot 604. When the metal shield 5 needs to be removed, the clamping block 603 is pushed, causing the clamping block 603 to compress the first spring 602 and withdraw from the clamping slot 604, thereby releasing the metal shield 5.

[0028] A second mounting groove 605 is provided on the inner wall of the metal protective cover 5. There are two second mounting grooves 605. The second mounting groove 605 is connected to the card slot 604. A push block 606 is slidably installed inside the second mounting groove 605.

[0034] A branch line 301 is fixedly connected to the power line 3 , and a display screen 10 is fixedly mounted on the outer wall of the cylindrical mounting block 2 . The display screen 10 and the branch line 301 are connected to each other.

[0035] The thermistor 4 converts the temperature signal into an electrical signal and transmits it to the branch line 301 through the power line 3. The branch line 301 transmits the electrical signal to the display screen 10. The display screen 10 converts the electrical signal into a temperature value and displays it.

[0036] A flange 11 is fixedly connected to the outer wall of the cylindrical mounting block 2 .

[0037] The temperature sensor can be installed at a designated location, such as a pipeline, equipment, etc., through the flange 11, thereby improving the convenience of using the temperature sensor.

[0038] Working principle: When the temperature sensor is used, the battery 8 provides power to the thermistor 4, the display screen 10 and other components through the power line 3.

[0039] Thermistor 4 senses the temperature change of the object being measured, and its resistance value changes. The change in resistance value is transmitted to the display screen 10 through the power line 3, and the display screen 10 converts the electrical signal into the temperature value and displays it.

[0040] When the thermistor 4 needs to be repaired or replaced, the baffle 607 is pushed to make the push block 606 squeeze the card block 603, and the card block 603 withdraws from the card slot 604, releasing the fixation of the metal protective cover 5, and then the metal protective cover 5 is removed, and the thermistor 4 can be repaired or replaced.
