[0002] The windproof performance of sportswear fabrics is an important indicator to measure their functionality, which directly affects the comfort and safety of the wearer in outdoor sports. With the popularization of outdoor sports, the market demand for testing of windproof fabrics is increasing.

[0003] At present, the test devices for the windproof performance of fabrics in the existing technology usually use fans to simulate natural wind, fix the fabric samples through clamping mechanisms, and detect the pressure loss or leakage when the airflow passes through the fabric. However, traditional fan systems mostly have fixed wind speed output, which is difficult to simulate the directional wind in complex environments, and lack the optimization of airflow uniformity by the guide structure. Existing devices generally only focus on wind factors, and the actual use environment of sportswear is often accompanied by complex conditions such as high temperature and high humidity. However, most devices do not have integrated temperature control modules, and cannot evaluate the windproof stability of fabrics under high temperature conditions, which needs further improvement.

In addition, turning on the air guide component on the ventilation box 2 can adjust the wind speed, and can detect the wind resistance of the fabric body 9 under different wind speed adjustments.

[0036] See also Figure 1 、 Figure 5 and Figure 6In this embodiment, the first blowing assembly 6 includes a second air supply frame 61, an air supply tube 62, a first blower 63, a second fixing ring 64 and an electric heating wire 65; the second air supply frame 61 is fixedly connected to the other side of the ventilation box 2, the air supply tube 62 is fixedly connected to the other side of the second air supply frame 61, the air inlet end of the first blower 63 is fixedly connected to the other side of the air supply tube 62, the second fixing ring 64 is fixedly connected to the inner wall of the air supply tube 62, and multiple electric heating wires 65 are fixedly connected to the inner wall of the second fixing ring 64, - the first blower 63 provides basic wind input, the electric heating wire 65 is arranged in the air supply tube 62 to heat the airflow, and cooperates with the electric heating plate 47 to realize temperature loading on both sides of the fabric body 9, simulating the influence of high temperature environment on windproof performance, the second fixing ring 64 supports the electric heating wire 65 and ensures that the airflow passes through the heating area evenly.

[0037] See also Figure 1 、 Figure 5 and Figure 6 In this embodiment, the first wind detection mechanism includes a third fixing ring 66 and a wind force detector 67. The third fixing ring 66 is fixed to the inner wall of the air supply tube 62, and the first vertical block is fixed to the inner wall of the third fixing ring 66. The wind force detector 67 is fixed through the center of the first vertical block, and the first temperature sensor is fixed to the side wall of the first vertical block. The wind generated by the second air supply frame 61 is blown onto the wind force detector 67 through the inner wall of the second fixing ring 64. The wind detector 67 collects the initial wind speed output by the first blowing component 6 in real time, and the first temperature sensor synchronously monitors the supply air temperature to ensure the environmental adaptability and accuracy of the detection data.

[0038] See also Figure 1 and Figure 6 In this embodiment, the second wind detection mechanism includes a first fixing ring 51 and a wind speed tester 52. The inner wall of the air outlet box 5 is flush with the inner wall of the first air inlet slot 42. A second vertical block is fixed to the inner wall of the air outlet box 5. The wind speed tester 52 is fixed through the center of the second vertical block. A second temperature sensor is fixed to the side wall of the second vertical block.

The second temperature sensor monitors the temperature of the rear side of the fabric body 9 and compares it with the temperature data of the first wind detection mechanism to realize the coupled detection of the temperature field and the wind field, which can comprehensively evaluate the impact of high temperature on the windproof performance of the fabric.

[0039] See also Figures 1-6 In this embodiment, the ventilation box 2, the first air supply frame 3, the clamping box 4, the air outlet box 5 and the first blowing assembly 6 correspond to each other. Circular grooves are opened on both sides of the ventilation box 2. The inner wall of the circular groove is flush with the inner wall of the first air inlet groove 42. The circular groove is flush with the inner wall of the first air inlet groove 42 to ensure that the wind passes through the fabric body 9 in a straight line and vertically, avoiding airflow scattering or edge leakage due to channel misalignment, and improving the reliability of the detection results.

[0040] See also Figure 1 and Figure 3 In this embodiment, the inner diameter of the third air inlet slot 48 is not larger than the inner diameter of the first air inlet slot 42, and the inner diameter of the second air inlet slot 44 is equal to the inner diameter of the first air inlet slot 42. The equal diameter design of the second air inlet slot 44 and the first air inlet slot 42 ensures that the flow rate is stable when the airflow passes through the placement plate 43, avoiding sudden changes in wind speed caused by local diameter reduction. The slightly smaller inner diameter of the third air inlet slot 48 can slightly increase the wind pressure on the rear side of the fabric body 9, simulating the pressure difference on both sides of the fabric in actual use, so that the detection conditions are closer to the real environment.

[0041] See also Figure 1 、 Figure 7 and Figure 8 In this embodiment, the second blowing assembly 8 includes an air supply channel 81, a fixed body 82 and a second blower 83; the left and right ends of the ventilation box 2 are both frame-shaped, and the left and right ends of the ventilation box 2 are fixed with one end of the air supply channel 81, the air supply channel 81 is U-shaped, and the other end of the air supply channel 81 is fixed with a fixed body 82, and the fixed body 82 is fixed with evenly distributed second blowers 83 in a through-type manner. The U-shaped air supply channel 81 introduces the wind force of the second blower 83 from the left and right ends of the ventilation box 2, and the evenly distributed second blowers 83 provide lateral wind force, which is mixed with the forward wind force of the first blowing assembly 6 to form a multi-directional composite airflow, which solves the shortcomings of the single flow direction simulation of the traditional device and realizes the wind resistance test under different wind pressure and wind direction conditions.

[0042] See also Figure 1 and Figure 3 In this embodiment, a controller 7 is fixedly connected to the upper end of the base plate 1, and a handle is fixedly connected to the upper end of the electric heating plate 47. The controller 7 integrates the control of the electric heating plate 47, the hair dryer, the motor 21 and other equipment to realize the automation of the detection process and improve the test efficiency. The handle of the electric heating plate 47 is convenient for manual installation and disassembly, and the placement design of the fixed frame 41 in the groove 10 is convenient for fabric sample replacement and equipment maintenance.

[0043] Example 2: Please refer to Figure 5 On the basis of Example 1, the present application provides a technical solution: the air guide assembly includes a motor 21, a rotating rod 22 and an air guide plate 23; two motors 21 are fixedly connected to the upper end of the ventilation box 2, the lower end of the output shaft of the motor 21 passes through the upper end of the ventilation box 2 and is fixedly connected to the rotating rod 22, and the side wall of the rotating rod 22 is fixedly connected to the air guide plate 23. The motor 21 drives the rotating rod 22 to drive the air guide plate 23 to rotate, and the direction and uniformity of the airflow in the ventilation box 2 are adjusted by changing the angle of the air guide plate 23. In combination with the lateral wind force of the second blowing assembly 8, the complex wind speed and wind direction changes in the natural environment can be accurately simulated, further improving the accuracy of the airflow change simulation and the environmental adaptability of the detection device.

[0044] Example 3: The difference from Example 1 is that the present application provides a technical solution: the third air inlet slot 48 is not provided on the electric heating plate 47. When in use, the electric heating plate 47 is placed on the end of the inner wall of the fixed frame 41 away from the first blowing assembly 6, so that the electric heating plate 47 and the end of the fabric body 9 that are close to each other are in contact with each other. The electric heating plate 47 is turned on to heat the fabric body 9. After heating for a period of time, the electric heating plate 47 is taken out of the fixed frame 41. This can simulate the working condition in which the fabric is first heated and then exposed to wind in actual use, thereby improving the detection effect of the detection device on complex high-temperature environments.

[0045] Working principle: When in use, first place the fabric body 9 on the inner walls of the two mounting grooves 45 of the placement plate 43, manually rotate the bolts 46 at the upper and lower ends of the placement plate 43, so that the bolts 46 pass through the wall layer of the placement plate 43 and squeeze the outer wall of the fabric body 9, thereby pressing the fabric body 9 to the inner wall of the mounting groove 45;

[0046] Next, place the placement plate 43 on the inner wall of the fixed frame 41 near the end of the first blowing assembly 6, and place the electric heating plate 47 on the inner wall of the fixed frame 41 away from the first blowing assembly 6, so that the electric heating plate 47 and the fabric body 9 are in contact with each other. Turn on the electric heating plate 47 to heat the fabric body 9 to simulate a high temperature environment;

[0047] Subsequently, the first blowing assembly 6 is turned on, and the first blower 63 supplies air to the ventilation box 2 through the air supply tube 62. The electric heating wire 65 in the air supply tube 62 can heat the airflow, and the heated airflow enters the ventilation box 2 through the second air supply frame 61. At this time, the wind force detector 67 of the first wind detection mechanism detects the initial wind speed in the air supply tube 62 in real time, and the first temperature sensor monitors the air supply temperature;

[0048] The wind acts vertically on the fabric body 9 through the circular grooves on both sides of the ventilation box 2, the first air inlet groove 42 of the fixed frame 41, and the second air inlet groove 44 of the placement plate 43. The air flow passing through the fabric body 9 enters the air outlet box 5 through the third air inlet groove 48 of the electric heating plate 47. The wind speed tester 52 of the second wind detection mechanism detects the wind speed, and the second temperature sensor monitors the temperature of the back side of the fabric body 9. The first wind detection mechanism first measures the initial wind speed. The second wind detection mechanism measures the wind speed , through the formula: windproof efficiency = (1- / ) × 100% calculates the fabric's ability to block wind. The higher the value, the stronger the windproof performance.

[0049] At the same time, the second blowing components 8 at the left and right ends of the ventilation box 2 are turned on, and the evenly distributed second blowers 83 blow lateral wind into the ventilation box 2 through the U-shaped air supply channel 81, which mixes with the forward wind force of the first blowing component 6 to form a multi-directional composite airflow, simulating different wind pressure environments;

[0050] During testing, the air guide assembly can also be turned on, and the motor 21 drives the rotating rod 22 to rotate the air guide plate 23 to adjust the direction and uniformity of the air flow in the ventilation box 2, thereby achieving simulation of different wind speeds and directions;

[0051] During the testing process, the controller 7 integrates and controls the electric heating plate 47, the first blower 63, the second blower 83, the motor 21 and other equipment. The handle of the electric heating plate 47 is convenient for installation and removal, and the fixing frame 41 is placed in the groove 10 of the bottom plate 1, which is convenient for replacing fabric samples and equipment maintenance, thereby comprehensively testing the windproof performance of the fabric body 9 under different temperature, wind pressure and wind speed conditions;

[0052] In addition, the third air inlet slot 48 may not be provided on the electric heating plate 47. At this time, the electric heating plate 47 is placed on the inner wall of the fixed frame 41 at the end away from the first blowing assembly 6, so that the electric heating plate 47 and the end of the fabric body 9 that are close to each other are in contact with each other. The electric heating plate 47 is turned on to heat the fabric body 9. After heating for a period of time, the electric heating plate 47 is taken out of the fixed frame 41. This can simulate the working condition in which the fabric is first heated and then exposed to wind in actual use.
