Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0032] The "multiple" involved in the embodiments of the present application means greater than or equal to two. It should be noted that in the description of the embodiments of the present application, the words "first" and "second" are only used for the purpose of distinguishing the description and cannot be understood as indicating or implying relative importance or order.

[0033] The terms "parallel" and "perpendicular" in this application refer to "substantially parallel" and "substantially perpendicular" in actual operation.

[0034] like Figure 1As shown, the material heat reflection performance testing device provided in the embodiment of the present application includes a device body, which is a sealed cubic structure formed by six covers 100, and at least one of the six covers 100 is a detachable structure. A heat source emitter 300 and a temperature detection unit are arranged in the device body, and each cover 100 includes a fabric layer 101, a lining layer 102 and a test layer distributed from the outside to the inside, so as to simulate clothing by distributing layered materials in sequence, so that the test layer is closer to the position in the actual clothing, and the test layer is detachably fixed to the lining layer 102 so as to be detachably fixed to the lining layer 102. Different materials are tested by replacing different test layers of the cover body 100. In this way, the test layer to be tested is connected to the bladder cloth layer 102, and a heat source is provided through the heat source emitter 300 to simulate the heat dissipation of the human body. The device body with a sealed cubic structure simulates the thermal insulation environment formed by the clothing wrapping the human body when the human body is wearing clothing. The temperature inside the device body is detected by the temperature detection unit, so that the test result can be closer to the actual thermal insulation effect of the test material on the human body when worn, thereby improving the accuracy of the thermal reflection performance test of the material in evaluating the thermal insulation effect of the material when actually worn.

[0035] In some embodiments, any one or two of the six cover bodies 100 can be detachably connected to adjacent cover bodies 100 to improve the convenience of replacing the test layer; of course, the six cover bodies 100 can also be detachably connected to further improve the convenience of replacing the test layer, which is not limited in this embodiment of the present application.

[0036] For example, Figure 4 As shown, in the device provided in the embodiment of the present application, the cover body 100 on the top surface can be detachably fixedly connected to the cover body 100 on the left side, the cover body 100 on the right side, the cover body 100 on the front side door, and the cover body 100 on the rear side through a zipper 110.

[0037] In order to make the device body form a stable cubic structure, such as Figure 1 As shown, adjacent covers 100 are supported and connected by connecting brackets 200 , and the supporting edges between adjacent covers 100 are supported by the connecting brackets 200 , so that the device body forms a stable cube, ensuring the stability of the detection process.

[0038] In some embodiments, the fabric layer 101 is Gore's windproof, waterproof and breathable material, and the lining layer 102 is 10D ultra-dense lining to further simulate the actual layered composition of clothing, so as to improve the sealing effect within the device body, and further make the test layer closer to the position in the actual clothing, so that the internal environment of the device body is closer to the actual insulation space formed between the human body and the clothing.

[0039] like Figure 2-Figure 3 As shown, the test layer includes a lining layer 104 and a protruding lining layer 105 sewn into an integral structure, wherein both the lining layer 104 and the protruding lining layer 105 are filled with filler 103 to simulate the insulation of actual clothing through the filler 103, so that the test layer is closer to the actual situation.

[0040] The protruding lining layer 105 is a strip structure filled with filler 103, and there are at least two protruding lining layers 105 in each test layer. The at least two protruding lining layers 105 are sewn to the inner side of the lining layer 104, and the at least two protruding lining layers 105 are parallel to each other and distributed in sequence along the same direction, so that the lining layer 104 and the protruding lining layer 105 form a test layer with a concave-convex structure, which is closer to the actual inner surface state of actual clothing after being filled with filler 103, so as to better simulate the temperature state of the space formed between the heat-reflective material inside the actual clothing and the human body, and further ensure the accuracy of the evaluation of the thermal insulation effect of the material under actual wearing conditions by the heat-reflective performance test of the material.

[0041] In some embodiments, each test layer may include two, three, four, or more protruding lining layers 105 to further simulate the inner surface state of actual clothing, which is not limited in this embodiment of the present application.

[0042] For example, Figure 2-Figure 3 As shown, in the embodiment of the present application, each test layer includes four protruding lining layers 105. The protruding lining layer 105 is sewn with the lining layer 104 to form a test layer with a concave and convex surface, so as to improve the accuracy of the evaluation of the heat reflection performance of the test layer.

[0043] In some embodiments, the test layer is bonded to the bile cloth layer 102 by Velcro to facilitate replacement of different test layers and improve detection efficiency.

[0044] In order to improve the bonding strength, the Velcro includes at least two, which can be two, three, four, etc., and the embodiments of the present application do not limit this.

[0045] In some embodiments, in order to facilitate bonding, each test layer can be composed of two, three or more structures. The lining layer 104 and the protruding lining layer 105 can be sewn into two, three or more structures, and then bonded to the bladder cloth layer 102 in turn through Velcro, thereby improving the convenience of the replacement process.

[0046] In some embodiments, the filling material 103 may be down, polyimide, or cotton wool, etc., which are filling materials capable of achieving thermal insulation, and this embodiment of the present application does not limit this.

[0047] like Figure 1As shown, the inner surface of the top cover body 100 is connected to a fixed bracket 500, the heat source emitter 300 is hung on the fixed bracket 500, and the fixed bracket 500 is distributed along the symmetry axis of the top cover body 100, so that the heat source emitter 300 is located in the middle area of ​​the top cover body 100, so that the heat source is emitted from the middle, which is closer to the actual situation of human body heat dissipation.

[0048] like Figure 1 As shown, the outer cover of the heat source emitter 300 is a cone with far-infrared carbon fiber wire built in, and the cone gradually expands from top to bottom to guide heat diffusion, further simulate the heat dissipation of the human body, and improve the uniformity of heat dissipation of the heat source.

[0049] It should be noted that the fixing bracket 500 can be connected to the bile cloth layer 102 of the top cover body 100, and two or more test layers can be bonded to the bile cloth layer 102 through Velcro to facilitate replacement of the test layers.

[0050] like Figure 1 As shown, the temperature detection unit includes: a temperature detection disk 400, which has a disc-shaped structure. A number of sensor probes 410 are distributed in sequence on the circumferential surface of the temperature detection disk 400. Specifically, 30 sensor probes 410 can be evenly distributed according to the circumference of the circumferential surface. The sensor probe 410 can be selected as a K-type thermocouple, which is wired for transmission, so that the output temperature data is more accurate. After the temperature is detected simultaneously by 30 sensor probes 410, the detected temperature average is output, thereby improving the accuracy of the temperature detection inside the device body.

[0051] The temperature detection unit also includes: a connecting rod 420, the first end of the connecting rod 420 is fixedly connected to the center position of the bottom surface of the temperature detection disk 400, and the connecting rod 420 is a hollow structure. A first through hole is opened in the middle of the temperature detection disk 400, and the first through hole is connected to the interior of the connecting rod 420, so that the connecting wire of the K-type thermocouple can pass through the first through hole and be routed along the inside of the connecting rod 420.

[0052] The temperature detection unit also includes: a fixed disk 430, the center position of the fixed disk 430 is fixedly connected to the second end of the connecting rod 420, a second through hole is opened in the middle of the fixed disk 430, the second through hole is connected to the inside of the connecting rod 420, and the bottom surface of the fixed disk 430 is sealed and connected to the center position of the inner surface of the bottom cover 100 to ensure the sealing of the internal environment of the equipment body and reduce the leakage of heat source. A third through hole is opened at the center position of the bottom cover 100, and the third through hole is connected to the second through hole, so that the connecting wire of the K-type thermocouple can be led out to the outside of the equipment body along the inside of the connecting rod 420, the second through hole, and the third through hole, so as to facilitate connection with other devices to obtain detection data.

[0053] In some embodiments, the temperature detection plate 400 and the fixing plate 430 are both made of acrylic boards to improve stability in different temperature environments.

[0054] It should be noted that the fixing plate 430 can be adhered to the bile cloth layer 102 of the bottom cover body 100, and two or more test layers can be adhered to the bile cloth layer 102 through Velcro to facilitate replacement of the test layers.

[0055] The materials that can be tested for the lining layer 104 and the protruding lining layer 105 of the test layer include: 1#: honeycomb technology heat storage lining, 2#: graphene lining, 3#: metal coating lining, 4#: HiQ honeycomb heat reflective lining, 5#: 20D anti-down matte nylon lining, 6#: 25D polyester cotton soft spinning lining.

[0056] By replacing different test layers and conducting heat reflection performance tests in the device provided in the embodiment of the present application, Table 1 can be obtained: Ambient temperature tests of different heat reflection materials and heat reflection test data of the material itself.

[0057] Table 1 Ambient temperature test data of different heat reflective materials and the heat reflective test data of the material itself

[0058]

[0059] Table 1 shows that Sample 2# (with the highest far-infrared temperature rise of 2.9°C and the highest internal temperature of 38.7°C) demonstrates that the material has a strong ability to block infrared heat radiation, resulting in a higher temperature inside the garment. Sample 3# (with the lowest far-infrared temperature rise of 1.5°C and the lowest internal temperature of 35.5°C) demonstrates a weaker ability to block infrared radiation, resulting in a lower temperature inside the garment. The other samples (1#, 4#, 5#, and 6#) all show a trend where the higher the far-infrared temperature rise, the higher the internal temperature.

[0060] It can be seen from this that the better the material's blocking effect on thermal radiation, the higher the temperature inside the clothing space, and the higher the far-infrared temperature rise value; detecting the temperature of the internal space of clothing through the equipment provided in the embodiment of this application can effectively predict the material's ability to block thermal radiation.

[0061] The material heat reflective performance testing device provided in the embodiment of the present application simulates the heat-insulating space formed between the human body and clothing by forming a sealed cubic device body, and uses Velcro to replace different test layers for testing to simulate the position of the actual heat reflective material on the clothing and its relationship with the human body. The temperature inside the device body is detected by multiple sensor probes to improve the accuracy of the test data, so that the test results can be closer to the actual heat-insulating effect of the test material on the human body when worn, thereby improving the accuracy of the evaluation of the heat-insulating effect of the material under actual wearing conditions by the heat reflective performance test of the material.

[0062] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application.
