In addition, the product needs to be dried after detection, resulting in a complex process.

[0003] Therefore, how to provide a temperature detection system with a simple and safe process has become a problem to be solved by those skilled in the art. SUMMARY

[0006] Optionally, a second circulating water path connected with the constant-temperature water tank is further arranged on the inner side of the top of the test cavity, and the second circulating water path is provided with a second heat conduction layer.

[0007] Optionally, a water path control module is further included, which is used for connecting the constant-temperature water tank with the first circulating water path and the second circulating water path, and controlling the flow rate of the first circulating water path and the second circulating water path.

[0008] Optionally, the water circuit control module includes a water distributor, a first flow switch, and a second flow switch. The inlet of the water distributor is connected to the outlet of the constant temperature water tank. The first outlet of the water distributor is connected to the inlet of the first flow switch.

[0022] This invention provides a temperature detection system for wearable devices, which has high safety and a simple testing process, thus improving testing efficiency.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please refer to Figure 1 , Figure 1This is a schematic diagram of a temperature detection system for a wearable device provided in an embodiment of the present invention. The temperature detection system includes a constant-temperature water bath 1 and a test chamber 2. The bottom of the test chamber 2 is provided with a first circulating water path 21 connected to the constant-temperature water bath 1. A first heat-conducting layer 22 is provided on the first circulating water path 21. A temperature-sensing element 23 is pre-embedded at the bottom of the test chamber 2. The constant-temperature water bath 1 heats the first heat-conducting layer 22 through the first circulating water path 21, keeping the temperature of the first heat-conducting layer 22 constant. The first heat-conducting layer 22 is used to heat the product to be tested placed on top of the first heat-conducting layer 22. The temperature-sensing element 23 is used to measure the temperature of the first heat-conducting layer 22.

[0025] It should be noted that, in this embodiment of the invention, when performing temperature detection on the product under test (e.g., a smartwatch), the product under test can be placed on the first thermally conductive layer 22 of the test chamber 2. Since the test chamber 2 is connected to the constant temperature water bath 1 through the first circulating water channel 21, and since the temperature of the liquid in the constant temperature water bath 1 is constant, the liquid in the constant temperature water bath 1 heats the test chamber 2 through the first circulating water channel 21, transferring the heat to the first thermally conductive layer 22 disposed on the first circulating water channel 21 to heat the first thermally conductive layer 22. The constant flow water channel forms a uniform thermal field on the first thermally conductive layer 22. To ensure the stability of the temperature inside the test chamber 2, the product under test placed above the first thermally conductive layer 22 is heated. Since a temperature sensing element 23 for detecting the temperature of the first thermally conductive layer 22 is pre-embedded at the bottom of the test chamber 2 in this embodiment, the temperature of the first thermally conductive layer 22 can be measured through the temperature sensing element 23, which also allows for the measurement of the actual temperature of the product under test. The measured temperature of the product under test is then read using its own temperature sensing function. Based on the actual temperature and the measured temperature, the temperature accuracy of the product under test can be further determined, achieving constant temperature testing of the product under test. The first thermally conductive layer 22 can be a thermally conductive layer made of thermally conductive silicone.

[0026] It should also be noted that the test chamber in this embodiment of the invention can be made of copper. A first circulating water channel 22 is provided at the bottom of the test chamber, and a copper plate is placed above the first circulating water channel 22. A first heat-conducting layer 22 is then placed above the copper plate to better conduct heat to the first heat-conducting layer 22. A top view of the bottom of the test chamber 2 is shown below. Figure 2 As shown, A is the inlet of the first circulating water path, B is the outlet of the first circulating water path, and C is the pre-embedded area of ​​the temperature sensing element. A first heat-conducting layer 22 (not shown) is provided above the temperature sensing element 23. The schematic diagram of the first circulating water path at the bottom is shown below. Figure 3 As shown, a cross-sectional view of the bottom structure of the test chamber is as follows. Figure 4 As shown.

[0027] Furthermore, the method may also include a second circulating water channel 24 disposed on the inner side of the top of the test chamber 2 and connected to the constant temperature water bath 1, and a second heat-conducting layer 25 disposed on the second circulating water channel 24.

[0028] Specifically, in order to further improve the heating rate within the test chamber 2, a second circulating water channel 24 can be provided on the inner top side of the test chamber 2. This second circulating water channel 24 is connected to the constant temperature water bath 1, and a second heat-conducting layer 25 is provided on the second circulating water channel 24. Alternatively, in practical applications, a corresponding circulating water channel can be provided inside the side wall of the test chamber 2 to improve heating efficiency. The second heat-conducting layer 25 can be a heat-conducting layer made of thermally conductive silicone.

[0029] Furthermore, in order to better control the flow rate of the first circulating water channel 21 and the second circulating water channel 22, such as... Figure 5 As shown, the system may also include a water circuit control module 3, which is used to connect the constant temperature water tank 1 with the first circulating water circuit 21 and the second circulating water circuit 24, and to control the flow rate of the first circulating water circuit 21 and the second circulating water circuit 24.

[0030] Specifically, such as Figure 6 As shown, the water circuit control module 3 includes a water distributor 31, a first flow switch 32, and a second flow switch 33. The inlet of the water distributor 31 is connected to the outlet of the constant temperature water tank 1. The first outlet of the water distributor 31 is connected to the inlet of the first flow switch 32. The outlet of the first flow switch is connected to the outlet of the constant temperature water tank 1 via the inlet component A1 of the first circulating water circuit 22 and the inlet component A2 of the second circulating water circuit 24. The second outlet of the water distributor 31 is connected to the inlet of the second flow switch 33. The outlet of the second flow switch 33 is connected to the inlet of the constant temperature water tank 1 via the outlet component B1 of the first circulating water circuit 22 and the outlet component B2 of the second circulating water circuit 24.

[0031] Furthermore, in order to achieve accurate temperature measurement, the temperature sensing element in this embodiment of the invention can be a platinum resistance thermometer. Of course, other temperature sensing elements can also be used in practical applications. This embodiment of the invention does not make any special limitation on which temperature sensing element to use.

[0032] To further improve the heating efficiency of the product under test, the system in this embodiment of the invention may further include a preheating device 4 for preheating the product under test so that the preheated product can be placed on the first heat-conducting layer 22 of the test chamber for heating. That is, in practical applications, to accelerate the heating of the product under test, it can be placed in the preset device 4 before being placed in the test chamber 2, and preheated by the preset device 4, for example, by heating the product to a preset temperature (e.g., 33°C), before being placed in the test chamber for heating. Specifically, after preheating, the preheated product can be transported to the first heat-conducting layer 22 of the test chamber 2 by the conveying mechanism 5 for heating. Specifically, a heating fan can be installed at the bottom of the preheating device 4 to provide a heating source, with a rated airflow of 5.5 m³ / s for a single fan. 3 / min, the total area of ​​the hot air zone is 5.9×10 -2 m 2 Without wind loss, the outlet air velocity is 1.5 m / s, thus providing a preset environment. The conveying mechanism can be constructed with three cylinders for three-axis conveying, enabling movement in the X / Y / Z directions. Specifically, the cylinders can first move the product to be tested, placed in the loading position, to the preset area of ​​the preheating device 4 for prediction, and then transport the preheated product to the first heat-conducting layer 22 of the test chamber 2 for heating.

[0033] As can be seen, the temperature detection system in this embodiment of the invention uses a constant temperature water bath connected to the test chamber to heat the first heat-conducting layer located on the first circulating water path within the test chamber. Since the temperature of the constant temperature water bath is constant, the temperature of the first heat-conducting layer can be kept constant. When performing temperature detection on the product under test, the product under test is placed on the first heat-conducting layer of the test chamber. Heat is transferred to the product under test through the first heat-conducting layer, thereby heating the product under test. The temperature of the first heat-conducting layer is measured by a temperature measuring element embedded in the bottom of the test chamber. Furthermore, the accuracy of the temperature measurement of the product under test can be determined by reading the temperature displayed by the product under test itself. This invention does not require waterproof performance of the product, has high safety, and the testing process is simple, which is conducive to improving testing efficiency.
