A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. Therefore, when testing a temperature sensor, its performance is also tested by detecting the temperature. However, existing temperature sensors usually only measure a single temperature, which makes the detection results of the temperature sensor prone to deviation, thus affecting the subsequent use of the temperature sensor. Therefore, a structure is designed to solve the problem that the detection effect of some existing temperature sensor detection devices is poor due to the single detection environment.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] The temperature sensor uses a detection device, such as... Figures 3-5As shown, the structure includes a support frame 1, which provides stable support for the overall structure, ensuring its stable function. The support frame 1 has a detection chamber 2 with a bottom opening. A detection box 3 is detachably connected inside the detection chamber 2. The detection box 3 has a detection slot 4 with a top opening for a temperature sensor. The detection box 3 is used to stably position and limit the temperature sensor, ensuring stable detection. An observation port 5 is provided on the inner top surface of the detection chamber 2, facing the detection slot 4. A transparent cover sheet 6, made of glass, is fixedly connected to the observation port 5 using adhesive. The combined effect of the transparent cover sheet 6 and the observation port 5 allows the user to observe the temperature sensor through the observation port 5 and the transparent cover. The element 6 enables stable observation of the temperature sensor detection process, ensuring a more convenient detection process. The support frame 1 is equipped with an air supply section that can supply air to the detection tank 4. The air supply section has several air outlets 7 arranged in an array, with the outlet temperature gradually changing along the array direction. The air supply section is slidably connected to the support frame 1, and its sliding direction is consistent with the array direction of the air outlets 7. The support frame 1 has air inlets 8 that can communicate with each of the air outlets 7 and with the detection tank 4. By sliding the air supply section, different air outlets 7 are connected to the detection tank 4, thereby allowing gas of different temperatures to be supplied into the detection tank 4, thus changing the temperature inside the detection tank 4 and providing different temperature environments for the temperature sensor detection process, thereby enabling multiple and stable detection of the temperature sensor.

[0026] like Figures 3-5 As shown, the detection box 3 has a connecting groove 9 that connects the air inlet 8 and the detection groove 4. Air entering from the air inlet 8 enters the detection groove 4 through the connecting groove 9, allowing the outside air to switch the temperature inside the detection groove 4. Magnetic sheets 10 that attract each other are fixedly connected to the cavity wall of the detection chamber 2 near the inner side and the outer wall of the detection box 3 by adhesive. The mutual attraction between the magnetic sheets 10 ensures that the state of the detection box 3 stored in the detection chamber 2 is more stable, thereby ensuring that the detection process and detection effect of the temperature sensor are more stable. A pull groove 11 is provided at the bottom of the detection box 3 near the outer side. The pull groove 11 allows the user to apply force to the detection box 3 more effectively, thereby better moving the detection box 3 and causing the temperature sensor to enter or exit the detection chamber 2.

[0027] like Figure 1 and Figure 2As shown, symmetrically arranged limiting plates 12 are fixedly connected to the top surface of the support frame 1 by welding. The air supply part includes a sliding strip 13. Near the bottom of the sliding strip 13, symmetrically arranged guide strips 14 are fixedly connected to it by welding. The limiting plate 12 has a guide groove 15 for the guide strip 14 to pass through and slide. Through the joint action of the guide strip 14 and the guide groove 15, the sliding process of the sliding strip 13 is stably guided and limited, ensuring that the sliding process of the sliding strip 13 is more stable, and at the same time, a stable sliding connection is achieved between the sliding strip 13 and the support frame 1.

[0028] like Figures 3-5 As shown, the bottom of the sliding bar 13 has several first sliding holes 16 arranged in an array along its length. The top wall of each first sliding hole 16 has a second sliding hole 17. A sliding tube 18, which slides vertically, is installed inside each second sliding hole 17. A sliding ring 19, which slides within the first sliding hole 16 and communicates with the sliding tube 18, is fixedly connected to the bottom of the sliding tube 18 by welding. An elastic ring 20, which communicates with the sliding ring 19 and abuts against the top surface of the support frame 1, is fixedly connected to the bottom of the sliding ring 19. The elastic ring 20 is made of EPDM rubber. The sliding tube 18... The outer side is fitted with a first elastic element 21, the two ends of which abut against the top wall of the sliding ring 19 and the first sliding hole 16 respectively. The first elastic element 21 is configured to be in a state of compression deformation when it abuts against the sliding ring 19 and the top wall of the first sliding hole 16. The elastic force generated by the elastic deformation of the first elastic element 21 is used to stably push the elastic ring 20 against the support frame 1, so that the state of communication between the elastic ring 20, the sliding ring 19 and the sliding tube 18 and the air inlet 8 is more stable, so that the gas sent from the sliding tube 18 can be better sent into the air inlet 8.

[0029] like Figures 3-5 As shown, an air outlet pipe 22 is fixedly connected to the detection box 3 and communicates with the detection tank 4. The air outlet 7 is located at the bottom of the air outlet pipe 22. The air outlet pipe 22 is connected to a vacuum pump. The suction force generated by the vacuum pump is used to draw the air out of the detection tank 4, making the air exchange process in the detection tank 4 more convenient. This allows air of different temperatures from the outside to flow into the detection tank 4, which can better change the temperature inside the detection tank 4 and thus better detect the temperature sensor.

[0030] like Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, a first through hole 23 is provided on the limiting plate 12 located on one side. A plurality of locking holes 24 are provided on the sliding strip 13, directly opposite the first sliding hole 16, with their central axes coplanar with the central axis of the first through hole 23. A locking rod 25, which can pass through the locking holes 24, is slidably connected within the first through hole 23. A pull block 26 is fixedly connected to the locking rod 25 by welding. The pull block 26 allows the user to apply force to the locking rod 25 and pull it to slide, thus achieving stable adjustment of the position of the locking rod 25. The pull block 26 and the limiting plate 12... A second elastic element 27 is fixedly connected to the locking rod 25 by welding. When the locking rod 25 is inserted into the locking hole 24 and abuts against the wall of the opening of the locking hole 24, the second elastic element 27 is in a state of being stretched and deformed. The elastic force generated by the elastic deformation of the second elastic element 27 can push the locking rod 25 to better penetrate into the locking hole 24 and realize the stable limiting of the sliding bar 13 during the sliding process, so that the sliding bar 13 can be in a relatively stable position, ensuring that the air outlet 7 of the sliding tube 18 can better communicate with the air inlet 8, and realize the stable air supply to the air inlet.

[0031] like Figures 3-7 As shown, a force-applying rod 28 is fixedly connected to the sliding bar 13 on the side away from the locking rod 25 by welding. The force-applying rod 28 allows the user to apply force to the sliding bar 13 more effectively, thereby pushing the sliding bar 13 to slide. The sliding of the sliding bar 13 drives the sliding tube 18 to slide, so that different sliding tubes 18 can connect to the air inlet 8 one by one and send air into the air inlet 8. This allows gases of different temperatures to be sent into the detection tank 4, so that the temperature in the detection tank 4 can change and realize the detection of different temperatures of the temperature sensor, enabling multiple and sufficient detection of the temperature sensor.
