[0031] It also includes a motor 12, a worm 13, a sleeve 14 and a worm gear 15; the water diversion plate 5 is installed with the motor 12; the output shaft of the motor 12 is fixedly connected to the worm 13; the water diversion plate 5 is rotatably connected to the sleeve 14; the sleeve 14 is movably connected to the support rod 11; the upper part of the outer ring surface of the sleeve 14 is fixedly connected to the worm gear 15; the worm gear 15 is meshed with the worm 13.

[0032] The structure also includes a pressure rod 16 ; the lower portion of the support rod 11 is hingedly connected to the pressure rod 16 ; a torsion spring is provided between the pressure rod 16 and the support rod 11 for resetting the pressure rod 16 .

[0033] The lower part of the pressure rod 16 is detachably connected with a spherical head, so that the spherical head of the pressure rod 16 can be easily replaced after being worn.

[0034] An electric heating wire is also provided in the spherical head of the pressure rod 16 for heating the sportswear fabric sample 001, simulating the effect on the breathability of the sportswear fabric sample 001 caused by the temperature rise of the sportswear fabric sample 001 after the human body comes into contact with the sportswear fabric sample 001.

[0035] It also includes a protective cover 17; the lower cylinder 1 is fixedly connected to the protective cover 17; the protective cover 17 is located at the pipe mouth of the suction pipe 4; the protective cover 17 is fixedly connected to the gas sensor 18; and a filter cloth is provided on the protective cover 17.

[0036] A silicone pad is provided on the facing sides of the lower cylinder 1 and the upper cylinder 2 to seal the upper opening of the lower cylinder 1 and increase the friction between the lower cylinder 1 and the sportswear fabric sample 001 to prevent the sportswear fabric sample 001 from sliding.

[0037] The working steps of the above embodiment are:

[0038] Before using the air permeability testing equipment, the operator first needs to cut the sportswear fabric to obtain a sportswear fabric sample 001 with regular edges, and then the operator removes the fastener 3 from the handles of the lower cylinder 1 and the upper cylinder 2, and then moves the upper cylinder 2 away from the top of the lower cylinder 1, and then the operator naturally flattens the sportswear fabric sample 001 and covers it on the lower cylinder 1, and then the operator covers the upper cylinder 2 on the sportswear fabric sample 001, and then uses the fastener 3 to clamp it on the handles of the lower cylinder 1 and the upper cylinder 2 to fix the lower cylinder 1 and the upper cylinder 2 together, wherein the silicone pad layer on the opposite sides of the lower cylinder 1 and the upper cylinder 2 clamps the sportswear fabric sample 001, which not only serves as a seal for the lower cylinder 1, but also adapts to irregular The air tightness test of sportswear fabric sample 001 of the same thickness has a wide range of applicability. Then, by connecting the suction tube 4 to the external pump, the external pump draws out the air in the lower cylinder 1 through the suction tube 4. The lower cylinder 1 is under negative pressure, and the outside air first enters the upper cylinder 2, and then the air passes through the sportswear fabric sample 001 and enters the lower cylinder 1, and then the air enters the suction tube 4 through the gas sensor 18. The gas sensor 18 is connected to the computer. Here, the air flow passing through the gas sensor 18 represents the air permeability of the sportswear fabric sample 001. The gas sensor 18 obtains the air permeability data curve of the sportswear fabric sample 001 in the initial state. When the curve state tends to be stable, this data is used as the initial air permeability data of the sportswear fabric sample 001.

[0039] Next, considering that the sportswear will sweat during use, in order to maintain the comfort of the user, the sportswear generally has the function of absorbing moisture. After the sportswear absorbs moisture, the moisture blocks the pores of the sportswear, which will affect the breathability of the sportswear. At this time, the atomizing nozzle 7 is controlled to start, and the physiological saline simulating human sweat in the water distribution tray 5 is evenly atomized and sprayed downward, so that the sportswear fabric sample 001 is evenly wetted by the atomized saline. At the same time, the humidity sensor in the upper cylinder 2 is used to monitor the humidity changes in the upper cylinder 2 in real time. The atomizing nozzle 7 is used to simulate the situation that the human body sweats more as the exercise time increases during exercise. At this time, the lower cylinder 2 is controlled to start the atomizing nozzle 7. 1 is used to extract air, and then the air flow rate at this time is measured by the gas sensor 18 to obtain the air permeability data of the sportswear fabric sample 001 at this time. This simulates the influence of the sportswear absorbing sweat on the air permeability of the sportswear during use. By comparing the data at this time with the original air permeability data, the influence of the sportswear being wetted by sweat on the air permeability of the sportswear can be obtained, which in turn affects the user's experience of using the sportswear. Then, the atomizing nozzle 7 is controlled to be closed, and the water vapor on the wetted sportswear fabric sample 001 begins to evaporate under the influence of continuous air extraction by the lower cylinder 1 and is extracted by the external pump until the sportswear fabric sample 001 is dry. Then the next test can be started.

[0040] It should also be taken into account that during the use of sportswear, the sportswear will directly contact with the user's limb joints and cause pulling, which will cause the sportswear to deform. The deformation will change the pores of the sportswear, and then change the breathability of the sportswear. Therefore, the two electric actuators 8 are controlled to contract, and the connecting rod 9 and the corresponding parts thereon are synchronously driven to move downward. The support rod 11 drives the pressure rod 16 to move downward. The pressure rod 16 presses down the middle part of the sportswear fabric sample 001 and deforms it. By controlling the downward pressure distance of the pressure rod 16, the sportswear fabric sample 001 can be controlled. 01's deformation degree, and then the air is extracted through the suction tube 4, and then the air permeability data of the sportswear fabric sample 001 at different pores is obtained. At this time, combined with the influence of water absorption of the sportswear, the atomizing nozzle 7 is controlled to start, the sportswear fabric sample 001 is wetted, and is also pressed down and deformed by the pressure rod 16. At this time, air is extracted through the suction tube 4, and then the air permeability data of the sportswear fabric sample 001 that is closer to the actual use process is obtained, so that the air permeability data has more practical reference significance for the production of sportswear.

[0041] On the basis of the above test, only by vertically pressing down the pressure rod 16, only the detection effect of a single position of the sportswear fabric sample 001 can be obtained. In order to obtain a more comprehensive detection effect, the support rod 11 and the pressure rod 16 are connected in a hinged manner, and a torsion spring is added between the support rod 11 and the pressure rod 16. Therefore, after completing the downward pressure test of the pressure rod 16, the deformation of the middle part of the sportswear fabric sample 001 reaches the maximum. At this time, the support rod 11 is moved downward again, and the pressure rod 16 rotates with the support rod 11. Due to the presence of the torsion spring, the lower part of the pressure rod 16 is still pressed on the sportswear fabric sample 001. Figure 9 As shown, the motor 12 is controlled to be started, and the output shaft of the motor 12 drives the worm 13 to drive the worm gear 15 to rotate. The worm gear 15 drives the sleeve 14 to drive the support rod 11 to rotate, and synchronously drives the pressure rod 16 to rotate. The lower portion of the pressure rod 16 performs a circular motion on the sportswear fabric sample 001. In conjunction with the downward movement distance of the support rod 11, the contact position between the pressure rod 16 and the sportswear fabric sample 001 can be controlled to change. The electric heating wire in the spherical head of the lower portion of the pressure rod 16 is controlled to be started, so that the temperature of the spherical head of the lower portion of the pressure rod 16 is increased to 37 degrees Celsius. This is used to simulate the effect of the temperature increase of the user's limbs on the air permeability of the sportswear fabric sample 001 during actual exercise. In this way, the sportswear fabric sample 001 can be squeezed and deformed at different positions to detect the effect of different tensions at the contact position on the air permeability of the sportswear fabric sample 001. In this way, the actual air permeability of the sportswear can be measured when the user's limbs move during actual exercise, causing the sportswear to be pulled by the limbs.

[0042] By comparing and analyzing the above test data, we can get the comprehensive breathability performance results of the sportswear fabric sample 001. Compared with the existing technology, the breathability test of sportswear in the existing technology only stays at the initial breathability test stage of this device, and the initial breathability data can only show the influence of the material of the sportswear fabric sample 001 on the breathability, and cannot fully reflect the breathability performance of the sportswear and the actual experience of the user when wearing the sportswear in actual use. This device can simulate the user's sweating during use by wetting the sportswear fabric sample 001. Afterwards, the sweat is absorbed by the sportswear, and the sweat blocks the pores of the sportswear, so that the breathability of the sportswear changes. Further, pressure is applied to the sportswear fabric sample 001 through the pressure rod 16, and the spherical head of the pressure rod 16 is heated to deform the sportswear fabric sample 001. In addition, the position where the pressure rod 16 applies pressure to the sportswear fabric sample 001 is changed, so that deformation occurs at different positions of the sportswear fabric sample 001, resulting in the stretching of the sportswear fabric sample 001. The performance of the breathability of the sportswear fabric sample 001 in actual use is then comprehensively evaluated to determine the quality of the breathability of the sportswear fabric sample 001.

[0043] Second embodiment

[0044] On the basis of the first embodiment, according to Figure 1-Figure 3 and Figure 6-Figure 9 As shown, it also includes an air pump 101, a conduit I 102, a conduit II 103 and a powder barrel 104; a partition is provided in the lower cylinder 1, which divides the lower cylinder 1 into two separate spaces, the suction pipe 4 is connected to the upper space of the lower cylinder 1, and the air pump 101 is installed in the lower space of the lower cylinder 1; the input end of the air pump 101 is connected to the suction pipe 4; the output end of the air pump 101 is connected to the conduit I 102; the conduit I 102 is detachably connected to the conduit II 103; a powder barrel 104 is installed on the upper part of the upper cylinder 2, and the powder barrel 104 is equipped with a solenoid valve for quantitatively controlling the discharge of powder; the discharge port of the powder barrel 104 is connected to the conduit II 103; the support rod 11 is a hollow rod; the conduit II 103 is connected to the support rod 11 through the hollow tube 10.

[0045] It also includes a connecting pipe 105; two symmetrically distributed connecting pipes 105 are installed at the lower part of the support rod 11; the pressure rod 16 is a hollow rod; the pressure rod 16 is connected to all the connecting pipes 105.

[0046] It also includes a sealing piece 106; a plurality of air holes 1601 are opened on the pressure rod 16; a plurality of sealing pieces 106 are hingedly connected to the pressure rod 16, and the lower portion of the sealing piece 106 is movable; each sealing piece 106 corresponds to one air hole 1601.

[0047] The working steps of the above embodiment are:

[0048] On the basis of the first embodiment, it should also be considered that during the actual use of sportswear, dust and impurities will adhere to the surface of the sportswear, or the oil secreted by the skin will combine with the dust and impurities. During the contact between the skin and the sportswear, the oil and dust impurities will be transferred to the sportswear. The combination of oil and dust impurities will block the pores of the sportswear, affecting the breathability of the sportswear. Therefore, by directly connecting the input end of the air pump 101 with the suction pipe 4, and then inserting the lower end of the conduit II 103 into the conduit I 102, and in advance The powder barrel 104 is filled with fine powder. When the air pump 101 evacuates the lower cylinder 1, the extracted gas enters the conduit II 103 through the conduit I 102, and then the air enters the hollow tube 10 from the conduit II 103. Before the air enters the hollow tube 10, the solenoid valve of the powder barrel 104 is controlled to open, and the powder enters the conduit II 103. Then, the powder is mixed with the air and enters the support rod 11 together. Then, the air mixed with the powder enters the pressure rod 16 through the connecting pipe 105. When the pressure rod 16 is tilted, Figure 9As shown, the sealing piece 106 on the lower side is separated from the air hole 1601, while the air hole 1601 on the upper side is still blocked by the sealing piece 106. The air entering the pressure rod 16 is ejected along the air hole 1601, and the dust is also evenly ejected onto the surface of the sportswear fabric sample 001. Then, as the pressure rod 16 rotates along the surface of the sportswear fabric sample 001, and the atomizing nozzle 7 sprays salt water mist onto the surface of the sportswear fabric sample 001, it simulates the dust impurities being wetted by sweat and adhering to the sportswear fabric. The surface of the material sample 001 is shown in FIG1 , wherein the sealing piece 106 blocks the air hole 1601 on the upper side, effectively preventing the salt water mist from entering the pressure rod 16, causing the dust to combine with moisture in the pressure rod 16 and the air hole 1601 to be blocked by the wet dust. At this time, the sportswear fabric sample 001 is vacuumed to obtain the final air permeability data under the influence of the comprehensive conditions at this time, thereby having a more comprehensive understanding of the air permeability performance of the sportswear fabric sample 001 and contributing to a comprehensive evaluation of the air permeability effect of the sportswear.

[0049] By integrating the air pump 101 into the lower cylinder 1, not only the weight of the lower cylinder 1 can be increased, and the center of gravity of the device can be moved downward, so that the device can operate stably during the detection process, and the extracted gas can be reintroduced into the upper cylinder 2, and the dust can also be brought into the upper cylinder 2, so that the dust is evenly distributed on the surface of the sportswear fabric sample 001, which is convenient for simulating the effect of sweat, grease and dust adhering to the sportswear during actual use of the sportswear fabric sample 001, and the impact on the breathability of the sportswear, and then comprehensively evaluating the breathability performance of the sportswear fabric sample 001.

[0050] It should be understood that this embodiment is only used to illustrate the present invention and is not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall equally within the scope limited by the appended claims of the application.
