Description

Technical Field

[0001] This utility model relates to the field of testing device technology, specifically a testing device for the thermal conductivity of an improved cooling agent. Background Technology

[0002] Cooling agents lower body surface temperature by accelerating the conduction of heat from the skin surface to the fabric. For example, additives containing highly thermally conductive ingredients (such as xylitol and peppermint oil) can quickly dissipate body heat; ingredients such as xylitol undergo an endothermic reaction when in contact with sweat, absorbing heat to achieve cooling; peppermint essential oil generates a cooling sensation by evaporating and dissipating heat; some cooling agents use phase change materials (such as modified alkanes) to absorb or release heat when the temperature changes, dynamically regulating the perceived body temperature.

[0003] After the cooling agent is produced, in order to understand its specific thermal conductivity performance, the batch of cooling agent is tested. Specifically, a portion of the cooling agent from the batch is sampled for the production of cooling products, thus obtaining test samples. Subsequently, items using the batch of cooling agent are tested using professional instruments (such as the Japanese KES-F7 precision instantaneous thermal property tester). However, during the above testing process, it was found that if the tested items are wrinkled when placed on the platform, resulting in unevenness of the tested samples, the test results will be inaccurate. Therefore, we propose an improved device for testing the thermal conductivity performance of cooling agents. Summary of the Invention

[0004] Therefore, the purpose of this invention is to provide a device for testing the thermal conductivity of an improved cooling agent, in order to solve the technical problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for testing the thermal conductivity of an improved cooling agent, comprising a platform, a top plate above the platform, and a limiting frame installed on the bottom end face of the top plate. An electric guide rail is installed inside the limiting frame, and a slider adapted to the electric guide rail is sleeved on the outer wall of the electric guide rail. The slider is slidably connected to the inner wall of the electric guide rail. An electric push rod is fixedly connected to the bottom end of the slider, and a pressure plate for leveling and pressing the test sample is connected to the output end of the electric push rod.

[0006] By adopting the above technical solution, the test sample can be flattened and pressed, ensuring the accuracy of the cooling agent test results. In addition, while the pressing plate flattens the test sample, it can also remove dust and impurities on the test sample, further improving the accuracy of the test results.

[0007] The present invention is further configured such that an extension plate is fixedly connected to the outer wall of the pressure plate, and an exhaust fan is installed inside the extension plate. An air intake is provided at the bottom end of the extension plate, the input end of the exhaust fan extends into the air intake, an exhaust box is connected to the outer side of the output end of the exhaust fan, and an exhaust pipe extending to the outside is connected to the top of the exhaust box.

[0008] By adopting the above technical solution, the gas can be discharged.

[0009] The present invention is further configured such that a driven turntable is installed on the side of the platform, and a drive turntable is installed above the driven turntable on the side of the top plate via a torsion spring shaft, and a transmission belt for transmission is connected between the driven turntable and the drive turntable.

[0010] By adopting the above technical solution, the transmission turntable is driven.

[0011] The present invention is further configured such that a driven gear, which is rotatably connected to the inner wall of the top plate, is installed inside the top plate on one side of the drive turntable, and a synchronous shaft is connected between the driven gear and the drive turntable.

[0012] By adopting the above technical solution, the driving effect of the drive turntable is achieved.

[0013] The present invention is further configured such that a toothed plate for driving the driven gear to rotate is fixedly connected to the top end of the pressure plate.

[0014] By adopting the above technical solution, the driven gear is effectively driven.

[0015] In summary, the present invention has the following main advantages:

[0016] 1. This utility model, by setting a pressure plate, firstly places the sample to be tested on the platform, then activates the electric push rod, which drives the pressure plate to move onto the test sample and achieves initial pressure and limitation on the test sample. Subsequently, the electric guide rail is activated, which drives the slider to move, thereby driving the electric push rod to move. The movement of the electric push rod will drive the pressure plate to move synchronously, so the pressure plate will move to one side. During the movement of the pressure plate, the pressure plate will achieve flatness of the test sample. After the pressure plate moves to the end of the platform, the output end of the electric push rod will continue to move a short distance to achieve pressure and limitation on the test sample, ensuring the stability of the test sample during the test. Furthermore, during the movement of the pressure plate to one side, the pressure plate will synchronously drive the extension plate to move, and the exhaust fan located on the extension plate will remove dust and impurities from the test sample through the air intake, thereby further improving the accuracy of the test results. Moreover, the gas containing impurities and dust will be discharged into the exhaust box and finally discharged to the outside through the exhaust pipe, without affecting the test process.

[0017] 2. This utility model, by setting a toothed plate and a turntable, after completing the test of the thermal conductivity of the cooling agent of the test sample, starts the electric push rod to reset and move. At this time, the electric push rod will drive the pressure plate to move upward to release the pressure limit on the test sample. During this process, the toothed plate will move towards the driven gear until it meshes with the driven gear to drive the driven gear to rotate. After the driven gear rotates, it will drive the drive turntable to rotate through the synchronous shaft. After the drive turntable rotates, it will drive the transmission turntable to rotate through the transmission belt. After the transmission turntable rotates, it will drive the platform to rotate. After the platform rotates, the test sample on its end face will be automatically unloaded. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] A device for testing the thermal conductivity of an improved cooling agent, such as Figure 1-4 As shown, the device includes a platform 1, a top plate 2 on top of the platform 1, and a limiting frame 3 installed on the bottom end face of the top plate 2. An electric guide rail 4 is installed inside the limiting frame 3, and a slider 5 adapted to the electric guide rail 4 is sleeved on the outer wall of the electric guide rail 4. The slider 5 is slidably connected to the inner wall of the electric guide rail 4. An electric push rod 6 is fixedly connected to the bottom end of the slider 5, and a pressure plate 7 for leveling and pressing the test sample is connected to the output end of the electric push rod 6.

[0026] Furthermore, in this embodiment, an extension plate 8 is fixedly connected to the outer wall of the pressure plate 7, and an exhaust fan 9 is installed inside the extension plate 8. An air intake 10 is opened at the bottom end of the extension plate 8. The input end of the exhaust fan 9 extends into the air intake 10. An exhaust box 11 is connected to the outer side of the output end of the exhaust fan 9, and an exhaust pipe 12 extending to the outside is connected to the top of the exhaust box 11.

[0027] Please see Figure 1 , Figure 2 as well as Figure 4 A driven turntable 13 is mounted on the side of the platform 1, and a drive turntable 14 is mounted on the side of the top plate 2 above the driven turntable 13 via a torsion spring shaft. A transmission belt 15 for transmission is connected between the driven turntable 13 and the drive turntable 14.

[0028] Please see 1 and Figure 4 Inside the top plate 2, on one side of the drive turntable 14, there is a driven gear 16 that is rotatably connected to the inner wall of the top plate 2. A synchronous shaft is connected between the driven gear 16 and the drive turntable 14. The top of the pressure plate 7 is fixedly connected to a toothed plate 17 for driving the driven gear 16 to rotate, thereby driving the driven gear 16.

[0029] The working principle of this utility model is as follows: First, the sample to be tested is placed on the stage 1. Then, the electric push rod 6 is activated, which drives the pressure plate 7 to move onto the test sample and achieves initial pressing and limiting of the test sample. Then, the electric guide rail 4 is activated, which drives the slider 5 to move, thereby driving the electric push rod 6 to move. The movement of the electric push rod 6 will drive the pressure plate 7 to move synchronously. Therefore, the pressure plate 7 will move to one side. During the movement of the pressure plate 7, the pressure plate 7 will achieve flatness of the test sample. After the pressure plate 7 moves to the end of the stage 1, the output end of the electric push rod 6 will continue to move a small distance to achieve pressing and limiting of the test sample, ensuring the stability of the test sample during the test process.

[0030] Furthermore, as the pressure plate 7 moves to one side, the pressure plate 7 will simultaneously drive the extension plate 8 to move, and the exhaust fan 9 located on the extension plate 8 will remove dust and impurities from the test sample through the air intake 10, thereby further improving the accuracy of the test results. The gas containing impurities and dust will be discharged into the exhaust box 11 and finally discharged to the outside through the exhaust pipe 12, without affecting the testing process.

[0031] Finally, the process of human skin contacting the fabric was simulated using a precision instrument, namely the KES-F7 precision instantaneous thermal property tester, and the maximum heat flux density (Q-max value) at the moment of contact was recorded. The higher the Q-max value, the stronger the thermal conductivity of the cooling agent.

[0032] In addition, after completing the test of the thermal conductivity of the cooling agent of the test sample, the electric push rod 6 is activated to reset and move. At this time, the electric push rod 6 will drive the pressure plate 7 to move upward to release the pressure limit on the test sample. During this process, the toothed plate 17 will move towards the driven gear 16 until it meshes with the driven gear 16 to drive the driven gear 16 to rotate. After the driven gear 16 rotates, it will drive the drive turntable 14 to rotate through the synchronous shaft. After the drive turntable 14 rotates, it will drive the driven turntable 13 to rotate through the transmission belt 15. After the driven turntable 13 rotates, it will drive the platform 1 to rotate. After the platform 1 rotates, the test sample on its end face will be automatically unloaded.
