[0039] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0040] The temperature measuring probe of this utility model is described below with reference to the accompanying drawings.

[0041] like Figures 1 to 5 As shown, this utility model provides a temperature probe, which includes an insert housing 10 and a temperature measuring component. The insert housing 10 is used to extend into the detection port of the PCR detection module, and an installation hole 11 is provided on the insert housing 10. The temperature measuring component includes a positioning block 20, a thermometer 30 and a connecting wire 40. The positioning block 20 is disposed in the installation hole 11 and has a receiving hole 21. The thermometer 30 is disposed in the receiving hole 21 and is used to detect the temperature in the detection port. The connecting wire 40 passes through the insert housing 10 and extends into the receiving hole 21 to be electrically connected to the thermometer 30.

[0042] Specifically, the thermometer 30 is disposed in the receiving hole 21 of the positioning block 20. The receiving hole 21 is used for positioning and installing the thermometer 30, so that the installation position of the thermometer 30 relative to the positioning block 20 is fixed, which improves the installation stability of the thermometer 30. The positioning block 20 is installed in the mounting hole 11 of the insert housing 10. The insert housing 10 can be inserted into the detection port of the PCR detection module. The thermometer 30 is used to detect the temperature in the detection port and transmit the detection result through the connecting cable 40. In the temperature probe of this embodiment, the positioning block 20 has a receiving hole 21 for positioning and installing the thermometer 30, so that the installation position of the thermometer 30 relative to the positioning block 20 and the insertion housing 10 is fixed, which improves the consistency of mass production of temperature probes, effectively prevents the thermometer 30 from shaking or shifting in the insertion housing 10, resulting in large differences in the temperature measurement results of multiple temperature probes, improves production quality, and saves screening time. Furthermore, the temperature probe is positioned and installed by the receiving hole 21 on the positioning block 20 and by the mounting hole 11 on the insertion housing 10, which makes assembly convenient and quick, simplifies the manufacturing process, and improves the production efficiency of temperature probes.

[0043] In this embodiment of the invention, the receiving hole 21 is filled with thermal grease to form a thermal grease block 211, which wraps around the temperature sensor 30. Figure 5As shown, the accommodating hole 21 is filled with thermal grease, so that the temperature sensor 30 extending into the accommodating hole 21 is wrapped in the thermal grease. By baking the thermal grease to form a thermal grease block 211, the thermal grease block 211 wraps around the temperature sensor 30 and thus stably fixes the temperature sensor 30 in the accommodating hole 21, further preventing the temperature sensor 30 from shaking or shifting, and improving the temperature measurement accuracy of the temperature sensor 30. Moreover, the thermal grease block 211 can be formed by baking thermal conductive silicone grease in the prior art. The thermal grease block 211 has the advantage of good thermal conductivity, which allows the thermal grease block 211 to conduct the internal temperature of the detection port to the temperature sensor 30, thereby improving the response speed and detection accuracy of the temperature sensor 30.

[0044] In this embodiment of the utility model, the insert housing 10 includes an insert section 12 and a connecting section 13. The insert section 12 is connected to the connecting section 13. An installation hole 11 is provided on the insert section 12. The insert section 12 is used to extend into the detection port and fit with the detection port. The connecting section 13 is used to connect to the base 201 of the temperature measuring fixture 200.

[0045] like Figures 1 to 4 and Figure 6 As shown, the insertion section 12 has a mounting hole 11, in which a positioning block 20 is installed, and a thermometer 30 is installed in the positioning block 20. The insertion section 12 can be inserted into the detection port so that the thermometer 30 can detect the temperature in the detection port. The installation position of the thermometer 30 is fixed relative to the insertion section 12, which improves the consistency of mass production of temperature probes, reduces the temperature measurement difference between multiple temperature probes, and saves screening time. In addition, the connecting section 13 can be connected to the base 201 to fix the insertion section 12 relative to the base 201. The insertion section 12 is inserted into the detection port, and the base 201 plays a role in stabilizing and supporting the insertion section 12. The base 201 is provided with electronic components for electrical connection with the connecting line 40 so that the thermometer 30 can transmit the temperature measurement result to the electronic components for processing and transmission through the connecting line 40.

[0046] In this embodiment of the present invention, the insertion section 12 includes a guide section 121 and a transition section 122. The transition section 122 is connected to the connecting section 13. The guide section 121 is connected to the end of the transition section 122 away from the connecting section 13. The guide section 121 is provided with a mounting hole 11. The guide section 121 has a first guide edge 1211 and a second guide edge 1212. The distance between the first guide edge 1211 and the second guide edge 1212 is gradually reduced in the direction away from the transition section 122.

[0047] like Figures 1 to 4As shown, the guide portion 121 is connected to the connecting section 13 via the adapter portion 122. The guide portion 121 has a first guide edge 1211 and a second guide edge 1212 that are arranged opposite to each other. The distance between the first guide edge 1211 and the second guide edge 1212 gradually decreases in the direction away from the adapter portion 122, so that the size of the guide portion 121 gradually decreases in the direction away from the adapter portion 122, thereby facilitating insertion into the detection port and serving as a guide for the adapter portion to be inserted into the detection port. The mounting hole 11 is opened on the guide portion 121 to ensure that the thermometer 30 in the positioning block 20 extends into the detection port to accurately detect the heating temperature of the PCR detection module.

[0048] In this embodiment of the utility model, the positioning block 20 includes an adapter segment 22 and an extension segment 23. The adapter segment 22 is connected to the extension segment 23. The adapter segment 22 has a first support edge 221 and a second support edge 222. The first support edge 221 is arranged parallel to the first guide edge 1211, and the second support edge 222 is arranged parallel to the second guide edge 1212.

[0049] like Figures 1 to 5 As shown, mounting holes 11 are formed on the guide portion 121 and are adapted to the positioning block 20. The adapting section 22 of the positioning block 20 has a first support edge 221 and a second support edge 222 arranged opposite to each other. The first support edge 221 is parallel to the first guide edge 1211 and the second support edge 222 is parallel to the second guide edge 1212. The distance between the first support edge 221 and the second support edge 222 gradually decreases in the direction away from the adapter portion 122, so that the first support edge 221 and the second support edge 222 form a V-shaped structure to support the guide portion. The function of 121 is to improve the structural strength of the guide part 121. The extension section 23 of the positioning block 20 is connected to the adapter section 22 to increase the area of ​​the positioning block 20 and extend the length of the receiving hole 21, thereby providing sufficient installation space for the temperature sensor 30 and effectively preventing the temperature sensor 30 from falling out of the receiving hole 21. The structure is stable and reliable. The thermal grease block 211 is filled in the receiving hole 21. The increase in the length of the receiving hole 21 increases the volume of the thermal grease block 211, improves the thermal conductivity of the thermal grease block 211, and further improves the detection accuracy of the temperature sensor 30.

[0050] In this embodiment of the utility model, a limiting groove 131 is provided on the connecting section 13, and the limiting groove 131 is used for the limiting pressure block on the base 201 to extend into. Figures 1 to 4 and Figure 6As shown, the connecting segment 13 is used to connect with the base 201 and has a limiting slot 131. The limiting pressure block on the base 201 can extend into the limiting slot 131 to fix the connecting segment 13 relative to the base 201, effectively preventing the insertion segment 12 from shaking or shifting, and playing a role in stabilizing and supporting the insertion segment 12. In addition, the base 201 is provided with a clamping block 202, which is used to clamp the connecting segment 13. The limiting pressure block can be set on the clamping block 202 and extend into the limiting slot 131 to fix the connecting block, further improving the connection stability.

[0051] In this embodiment of the present invention, a locking groove 111 is provided on the wall of the mounting hole 11, and a locking flange 24 is formed on the edge of the positioning block 20, the locking flange 24 extending into the locking groove 111. Figures 2 to 4 As shown, the snap-fit ​​flange 24 extends along the outer periphery of the positioning block 20, so that the snap-fit ​​flange 24 can extend into and be embedded in the snap-fit ​​groove 111. The groove wall of the snap-fit ​​groove 111 acts to stop the snap-fit ​​flange 24, effectively preventing the positioning block 20 from coming out of the mounting hole 11 and improving the structural stability.

[0052] In this embodiment of the utility model, the insert housing 10 is integrally injection molded, and a plurality of injection positioning grooves 14 are formed on the insert housing 10. The plurality of injection positioning grooves 14 are arranged at intervals along the outer periphery of the mounting hole 11. The injection positioning grooves 14 are used to adapt to the injection limiting block on the injection mold.

[0053] like Figures 1 to 4 As shown, the insert housing 10 can be integrally injection molded using existing injection molding technology. The positioning block 20, which is equipped with the thermometer 30 and the connecting wire 40, is placed into the injection mold. Multiple injection limiting blocks on the injection mold abut against the positioning block 20 to limit its position. Injection material is injected into the injection mold to form the insert housing 10. An injection positioning groove 14 is formed on the insert housing 10 corresponding to the position of the injection limiting block. This ensures that the positioning blocks 20 of multiple temperature probes are fixed relative to the insert housing 10 during mass production of temperature probes. This effectively prevents the thermometer 30 from shaking or shifting, which could lead to large differences in the temperature measurement results of multiple temperature probes. This improves the dimensional consistency of mass production of temperature probes and the consistency of the installation position of the thermometer 30, thereby improving production quality. Furthermore, the edge of the positioning block 20 is formed with a snap-fit ​​flange 24. During the injection molding process of the insert housing 10, an insert groove 111 is formed on the insert housing 10, so that the snap-fit ​​flange 24 is embedded into the insert groove 111 to further limit the positioning block 20, and the assembly is stable and reliable.

[0054] In this embodiment of the invention, the positioning block 20 is made of aluminum alloy or copper. Specifically, the positioning block 20 is made of aluminum alloy or copper, giving it good thermal conductivity. A receiving hole 21 is formed on the positioning block 20, and thermal grease is injected into the receiving hole 21 to further improve the thermal conductivity. The temperature sensor 30, connected to the connecting wire 40, is inserted into the receiving hole 21, and the thermal grease wraps around the temperature sensor 30 to fix it in place and prevent it from shaking or shifting. The positioning block 20 is then placed in a centrifuge for centrifugation, allowing the air in the receiving hole 21 to be discharged, effectively preventing trapped air and improving production quality. Finally, the positioning block 20 is baked to solidify the thermal grease and form a thermally conductive material. The thermal grease block 211, which wraps around the temperature sensor 30, further improves the installation stability. The positioning block 20 is placed into the injection mold for injection molding, and the insert housing 10 is formed by injection molding. Injection molding ensures that the mass-produced insert housing 10 has high dimensional consistency, and the positioning block 20 plays the role of positioning and installing the temperature sensor 30, which improves the detection accuracy of multiple temperature probes. In addition, after the production is completed, the temperature probes are screened, and qualified temperature probes are placed in a constant temperature water bath for testing and calibration, thus completing the mass production of temperature probes. The temperature probe manufacturing process is simple and convenient, which greatly improves production efficiency.

[0055] In a preferred embodiment of this utility model, the positioning block 20 is made of 6061 aluminum alloy. The heat transfer rate of 6061 aluminum alloy is lower than that of copper. The reagent used in the PCR detection module is liquid, and the heat transfer rate of liquid is lower than that of copper. The positioning block 20, made of 6061 aluminum alloy, can accurately reflect the heating temperature of the liquid reagent by the PCR detection module, further improving the accuracy of temperature measurement.

[0056] Furthermore, this utility model also provides a temperature measuring fixture 200, which includes a temperature measuring probe as described above. For example... Figure 6 As shown, the temperature measuring fixture 200 also includes a base 201. The end of the insert housing 10 away from the positioning block 20 is connected to the base 201 to stably support the positioning block 20, so that the positioning block 20 can be inserted into the detection port so that the thermometer 30 can detect the temperature in the detection port.
