[0026] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects and do not necessarily have to be used to describe a specific order or sequence.

[0027] The terms "including" and "having" in the description and claims of the present application, and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those clearly listed steps or units, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products, or devices.

[0028] Such as Figures 1-8The T-shirt air permeability test device shown includes a supporting part 2 with an open end. The end face where the open end of the supporting part 2 is located is a plane. The T-shirt to be tested is flatly covered on the open end of the supporting part 2, forming a cavity between it and the inner wall of the supporting part 2. An electronic barometer 3 is arranged outside the supporting part 2, which can convert the physical air pressure value into an electronic signal. The specific structure of the supporting part 2 includes a negative pressure cover 201. The negative pressure cover 201 gradually bulges from the edge of the open end towards the middle. A handle 202 is also fixedly connected to the outer side of the negative pressure cover 201. Usually, two handles 202 are symmetrically arranged, close to the edge of the negative pressure cover 201. The outer side of the negative pressure cover 201 has an extension pipe 208. The extension pipe 208 is hollow. A communication hole 203 connected to the inside of the extension pipe 208 is opened on the inner wall of the negative pressure cover 201. In this way, the pressure inside the negative pressure cover 201 is the same as the pressure inside the extension pipe 208. The electronic barometer 3 is fixedly connected to the end of the extension pipe 208. The probe of the electronic barometer 3 is located inside the extension pipe 208, used to detect the air pressure inside the supporting part 2 and obtain the air pressure data inside the negative pressure cover 201 in real time.

[0029] An air pipe 6 is also connected outside the supporting part 2. The air pipe 6 is connected to the outer surface of the central bulge of the negative pressure cover 201. An electronic flow meter 4 is arranged on the air pipe 6, used to detect the air flow rate flowing through the air pipe 6 and convert the physical quantity of the air flow rate into an electronic signal. The other end of the air pipe 6 is connected to a fan 7, used to drive the air to generate an air flow. The input end of the fan 7 is connected to the inside of the supporting part 2 through the air pipe 6, used to extract the air inside the negative pressure cover 201 to generate negative pressure. A convection hole 204 penetrating the inner and outer walls is opened at the center of the negative pressure cover 201, used to connect the air pipe 6 and the inside of the negative pressure cover 201. The air pipe 6 includes two parts, a primary conduit 601 and a secondary conduit 602. The primary conduit 601 is connected between the negative pressure cover 201 and the electronic flow meter 4, while the secondary conduit 602 is connected between the electronic flow meter 4 and the fan 7. In fact, an insertion groove 207 is also opened on the outer side of the central bulge of the negative pressure cover 201, which just fits with the end of the primary conduit 601. Without using curing glue for fixation, good stability and airtightness can be achieved.

[0030] A processor 5 is also arranged on the back of the electronic flow meter 4, used to be electrically connected to the electronic barometer 3, the electronic flow meter 4 and the fan 7, obtain the detection information of the electronic barometer 3 and the electronic flow meter 4, and thus control the output power of the fan 7.

[0031] The T-shirt air permeability detection device further includes an annular pressing part 1. The inner diameter of the pressing part 1 is the same as the inner diameter of the opening of the negative pressure cover 201. The main body part of the pressing part 1 is a steel ring 101. A configuration groove 209 is provided on the end face where the opening of the negative pressure cover 201 is located. A magnetic attraction ring 205 is arranged in the configuration groove 209 of the negative pressure cover 201, which can magnetically attract the steel ring 101, so as to press the test part of the T-shirt against the end face where the opening end of the negative pressure cover 201 is located. A second friction ring 206 is fixedly connected to the end face where the opening of the negative pressure cover 201 is located, which can prevent the test part of the T-shirt from moving on the end face of the negative pressure cover 201. The second friction ring 206 covers the magnetic attraction ring 205. Since the second friction ring 206 is usually made of a soft elastic material such as rubber or silica gel, it can effectively prevent the magnetic attraction ring 205 from being broken by hard contact and impact with other components, and can better maintain the integrity of the magnetic attraction ring 205 during long-term use. Usually, a first friction ring 102 is fixedly connected to the corresponding end face of the steel ring 101, which is also in direct contact with the test part of the T-shirt, further suppressing the movement of the pressing part 1. The end face of the first friction ring 102 has friction grooves 104 to increase the contact friction force with the test part of the T-shirt. A lifting groove 103 is provided on the outer side surface of the steel ring 101. Since the steel ring 101 is usually made of stainless steel material and the surface is relatively smooth, the lifting groove 103 is convenient for fingers or nails to hold the steel ring 101, so as to overcome the magnetic attraction force and separate the pressing part 1 from the supporting part 2.

[0032] Working principle: When in use, first cover the T-shirt to be tested flatly on the opening of the negative pressure cover 201, and then attach the pressing part 1 to the other side of the test part of the T-shirt. The pressing part 1 will be automatically sucked tightly on the end face of the supporting part 2, so as to press and fix the test part of the T-shirt. Then start the blower 7 to extract the air in the negative pressure cover 201 to generate negative pressure. Due to the action of the air pressure difference, the air will pass through the test part of the T-shirt, causing an air flow in the air pipe 6. When these air flows pass through the electronic flow meter 4, their speeds will be detected. The rated flow rate value is set through the processor 5. When the flow rate is lower than this set value, the processor 5 will control the blower 7 to increase the output power; when it is higher than this set value, the processor 5 will control the blower 7 to reduce the output power, so as to control the flow rate of the air flow within the error range allowed by the set value. When the air flow rate is stable, the processor 5 will obtain the data of the electronic pressure gauge 3. The higher the data detected by the electronic pressure gauge 3, the better the air permeability of the T-shirt; the lower the detected data, the worse the air permeability of the T-shirt.
