[0025] Figure 1 It is a structural schematic diagram of a mesh detection device according to some embodiments of this specification.

[0026] In some embodiments, as Figure 1As shown, the mesh testing device includes a handheld clamp 100 and an airflow testing device 200. The airflow testing device 200 includes an air blowing device 210 and a testing device 220. The handheld clamp 100 includes two handheld rods 110, which are connected to the air blowing device 210 and the testing device 220, respectively. In some embodiments, the mesh to be tested is placed between the air blowing device 210 and the testing device 220. The two handheld rods 110 drive the air blowing device 210 and the testing device 220 to separate or engage, thereby loosening or clamping the mesh to be tested.

[0027] The handheld clamp 100 refers to the portion of the mesh testing device that the operator grasps or presses. The operator can grasp the handheld clamp 100 or apply a gripping force (e.g., pressing or pinching) to the handheld clamp 100. The airflow testing device refers to a device that performs airflow testing on a mesh to be tested to test its air permeability. In some embodiments, when the handheld clamp 100 is subjected to a gripping or pressing force, the airflow testing device 200 can open to allow the mesh to be placed. In some embodiments, the handheld clamp 100 can close to apply pressure to the mesh to be tested, thereby flattening the mesh to facilitate air permeability testing.

[0028] In some embodiments, as Figure 1 As shown, the handheld clamp 100 includes two handheld rods 110 , a rotating shaft 120 and a fixing member 130 . The rotating shaft 120 is located between the two handheld rods 110 , and the two handheld rods 110 are rotatably connected through the rotating shaft 120 ; the fixing member 130 limits the rotation angle of the two handheld rods 110 .

[0029] The shape of the handle bar 110 can be various, for example, a flat and long shape, a round rod shape, or a variable cross-section shape. The rotating shaft 120 is a circular shaft-shaped component. The rotating shaft 120 is located between the two handle bars 110, which means that the rotating shaft 120 is set in the middle position of the length direction of the handle bars 110. The two handle bars 110 can be rotatably connected by the rotating shaft 120, and the two handle bars 110 can be located on both sides of the rotating shaft 120 (such as Figure 1 As shown), or crossed into an X shape, the two hand-held rods 110 are rotatably connected to the rotating shaft 120 respectively.

[0030] In some embodiments, as Figure 1 As shown, the handheld wand 110 includes a handheld end 111 and a test end 112. Handheld end 111 refers to the portion held by the operator's hand; it can be configured in a convenient shape, such as an arc that fits snugly in the hand, a flat, elongated shape with a large gripping area, or with friction-enhancing patterns. Test end 112 refers to the end of handheld wand 110 that connects to the airflow detection device; see below for more information on test end 112.

[0031] The fixing member 130 is used to fix the positions of the two handle bars 110 to limit the rotation angle of the two handle bars 110. The fixing member 130 can have various structures. For example, the fixing member 130 can be a dovetail clip, a metal clip, or a strap to clamp or fix the two handle bars 110. In another example, the fixing member 130 can be a U-shaped member with its ends detachably connected to the two handle bars 110 (e.g., threaded connection) to secure or release the two handle bars 110.

[0032] In some embodiments, the fixing member 130 is a spring, and the two ends of the spring are respectively connected to the two hand-held rods; the rotating shaft 120 passes through the spring. A spring refers to a component that uses elasticity to deform under the action of an external force and return to its original shape after the external force is removed. The spring can include a tension spring, a compression spring, a torsion spring, etc. The two ends of the spring are respectively connected to the two hand-held rods, and the two ends of the spring can be fixedly connected to the two hand-held rods, or slidably connected. For example, the two ends of the spring are provided with straight segments, the hand-held rods are provided with an annular feature, and the straight segments of the spring pass through the annular feature of the hand-held rod. When the spiral segment of the spring is compressed or extended, the straight segments at both ends of the spring slide relative to the hand-held rod.

[0033] In some embodiments, as Figure 1 As shown, each of the two handle bars 110 includes a straight bar portion and a flange portion 113 , and the rotating shaft 120 is disposed through the flange portion 113 .

[0034] In some embodiments, the spring is arranged on the inner side of the two flange portions 113 of the two hand-held rods, and the spring is a compression spring (the rotating shaft is arranged next to the spring) or a torsion spring (the rotating shaft can pass through the spring); the hand-held end 111 of the hand-held rod 110 can be far away from the spring and the rotating shaft, so as to utilize the lever principle to save pressing force; when the operator presses or holds the two hand-held ends 111 to apply pressing force, the airflow inspection device 200 can be easily opened, and when the pressing force is released, the airflow inspection device 200 can be closed.

[0035] In some embodiments, the material of the handheld clamp 100 can be metal, plastic, or a mixture of the two; for example, the material of the handheld rod 110 is plastic, and the material of the rotating shaft 120 and the fixing member 130 is metal; this is not limited here.

[0036] The airflow testing equipment can blow air toward one side of the mesh to be tested and receive the airflow that passes through the mesh to be tested on the other side, thereby testing the air permeability of the mesh to be tested.

[0037] In some embodiments, the airflow testing device includes an air blowing device 210 and a detection device 220. In some embodiments, the air blowing device 210 and the detection device 220 are respectively connected to the test ends 112 of two handheld rods 110; the mesh to be tested can be placed between the air blowing device 210 and the detection device 220, and the two handheld rods 110 drive the air blowing device 210 and the detection device 220 to separate or engage, thereby loosening or clamping the mesh to be tested.

[0038] The blowing device 210 refers to a device in the airflow testing device that blows air toward the mesh. The detecting device 220 refers to a device that detects the airflow rate or flow rate on both sides of the mesh to be tested.

[0039] In some embodiments, the air blowing device 210 and the detection device 220 can be fixedly connected or detachably connected to the test ends 112 of the two handheld rods 110, respectively. Fixed connection can include fixing by screws, gluing, hot melt, etc. Fixed connection can also be achieved by integrally forming a portion of the air blowing device 210 and the detection device 220 with the two handheld rods 110. For example, the housing of the air blowing device 210 and the detection device 220 and the handheld rods 110 are integrally formed and made of plastic by injection molding or compression molding. Removable connection can include threaded connection, snap-fit ​​connection, etc.

[0040] In some embodiments, the two hand-held rods 110 drive the blowing device 210 and the detection device 220 to separate or cooperate. The operator can press the two hand-held rods 110 to rotate, thereby separating the blowing device 210 and the detection device 220; when the mesh to be tested is placed, the two hand-held rods 110 are released, thereby cooperating the blowing device 210 and the detection device 220 (fitting with both sides of the mesh to be tested).

[0041] Figure 2a is a schematic cross-sectional view of a mesh detection device according to some embodiments of this specification; Figure 2b is another cross-sectional schematic diagram of the mesh detection device shown in some embodiments of this specification.

[0042] For example, Figure 2a This is a diagram showing the separation of the air blowing device 210 and the detection device 220 after pressing the two hand-held rods 110; after the mesh A to be tested is placed between the air blowing device 210 and the detection device 220, the two hand-held rods 110 are released, as shown in FIG. Figure 2b As shown, the blowing device 210 and the detection device 220 cooperate to compress the mesh cloth A to be tested, thereby performing an air permeability test on the mesh cloth A to be tested.

[0043] In some embodiments, when the two hand-held rods are detachably connected to at least one of the blowing device and the detection device, the mesh A to be tested is placed between the blowing device 210 and the detection device 220, and the two hand-held rods 110 are released. Figure 2bAs shown, the blowing device 210 and the detection device 220 cooperate to compress the mesh A to be tested, thereby performing an air permeability test on the mesh A to be tested; when the mesh is inconvenient to place (such as a mesh cover with structural parts), one of the blowing device and the detection device can be disassembled at any time as needed (such as by releasing the snap connection). In some embodiments, blowing devices and detection devices of different specifications can also be configured (such as setting blowing devices and detection devices of different sizes to test different mesh sizes to be tested). Different specifications can be replaced through detachable connections according to the needs of the test site, thereby increasing the testing flexibility of the mesh detection device.

[0044] In some embodiments, the detection device 220 is a wind speed detector, which refers to an instrument capable of detecting wind speed, such as an anemometer, an ultrasonic wind speed sensor, and the like.

[0045] In some embodiments, the blowing device 210 and the detection device 220 have the same structure. For example, the blowing device 210 and the detection device 220 are both wind tubes or wind tube anemometers. The wind tube on one side (i.e., the blowing device 210) blows air to the mesh to be tested, and the wind tube on the other side (i.e., the detection device 220) receives the wind that passes through the mesh and passively rotates. By comparing the set wind speed and the passive rotation wind speed of the wind tubes on both sides, the air permeability of the mesh to be tested can be obtained. For more information about airflow testing equipment, see below. In some embodiments, the blowing device 210 can provide three wind speeds of high, medium and low or more wind speeds to meet different testing needs.

[0046] In some embodiments of the present specification, a handheld clamp and an airflow inspection device can be used to miniaturize the mesh detection device and make it easy to carry. At the same time, by setting the fixing part as a spring, the pressing force of the handheld clamp and the elastic force of the spring itself can be used to make the blowing device and the detection device loosen or clamp the mesh to be tested, which facilitates operation, improves test efficiency, reduces additional components, and reduces costs.

[0047] Figure 3 This is another structural schematic diagram of the mesh detection device shown in some embodiments of this specification. Figure 4 It is a schematic top view of a mesh detection device according to some embodiments of this specification. Figure 5 This is a schematic diagram of the AA cross-sectional view of the mesh detection device shown in some embodiments of this specification. Figures 3 to 5 The following embodiments are understood, but the accompanying drawings are only illustrative of some of the implementation methods and do not constitute a limitation of the implementation methods.

[0048] In some embodiments, as Figures 3 to 5As shown, the blowing device 210 includes a first shell 211 and a first air cylinder 212. The first shell 211 is provided with a first opening 211-1 and a second opening 211-2 relative to each other. The air inlet of the first air cylinder 212 faces the first opening 211-1, and the air outlet of the first air cylinder 212 faces the second opening 211-2. The detection device 220 includes a second shell 221 and a second air cylinder 222. The second shell 221 is provided with a third opening 221-1 and a fourth opening 221-2 relative to each other. The air inlet of the second air cylinder 222 faces the third opening 221-1, and the air outlet of the second air cylinder 222 faces the fourth opening 221-2. The second opening 211-2 is provided on the side of the detection device 220 close to the third opening 221-1. The mesh A to be tested (such as Figure 5 The air duct (shown in Figure 2) is placed between the first air duct 212 and the second air duct 222. The first housing 211 and the second housing 221 are respectively fixedly connected to the test ends of the two handheld poles; that is, the first housing 211 is fixedly connected to the test end of the handheld pole 110-1, and the second housing 221 is fixedly connected to the test end of the handheld pole 110-2. The air outlet refers to the side of the air duct where air flows out; the air inlet refers to the side where air enters the air duct, causing it to rotate.

[0049] In some embodiments, the end surfaces of the second opening 211-2 and the third opening 221-1 are flat to compress the mesh to be tested. In some embodiments, the sizes of the second opening 211-2 and the third opening 221-1 match, enabling testing of a mesh assembled from the mesh and related structural components. An exemplary operation for testing the mesh is as follows: an operator grasps the handheld clamp and applies a gripping force, separates the blowing device 210 and the testing device 220, and places the mesh between the first air cylinder 212 and the second air cylinder 222; the structural components of the mesh are located outside the first shell 211 and the second shell 221.

[0050] In some embodiments, as Figure 5 As shown, the second shell 221 includes an inner shell 221-3 and an outer shell 221-4. The inner diameter of the first shell 211 and the outer diameter of the inner shell 221-3 are clearance-matched, and the clearance is related to the thickness of the mesh A to be tested. The outer diameter of the first shell 211 is smaller than the inner diameter of the outer shell 221-4. It should be noted that the definition of inner diameter and outer diameter only refers to the inner diameter and outer diameter of the first shell 211 and the second shell 221 where they meet, and the sizes of other parts are not limited. The structures of the first shell 211 and the second shell 221 are interchangeable, that is, the first shell 211 includes an inner shell and an outer shell, and the inner diameter of the second shell 221 and the outer diameter of the inner shell are clearance-matched, and the clearance is related to the thickness of the mesh to be tested. The outer diameter of the second shell 221 is smaller than the inner diameter of the outer shell.

[0051] A clearance fit refers to a fit in which the inner diameter of the first shell 211 is larger than the outer diameter of the inner shell 221-3, so that a clearance exists between the first shell 211 and the inner shell 221-3 after the blowing device 210 and the detection device 220 are closed. In some embodiments, the clearance is related to the thickness of the mesh A to be tested, that is, the clearance is slightly larger than the thickness of the mesh A to be tested. For example, if the thickness of the mesh A to be tested ranges from 0.02mm to 2.0mm, the clearance is 3mm (that is, the inner diameter of the first shell 211 is 3mm larger than the outer diameter of the inner shell 221-3). It should be noted that, in order to facilitate the opening of the blowing device 210 and the detection device 220, the size of the overlapping portion where the first shell 211 is inserted into the second shell 221 or the second shell 221 is inserted into the first shell 211 can be smaller (for example, the overlapping size is one-quarter of the shell thickness) to avoid interference between the relatively tilted positions of the first shell 211 and the second shell 221 when rotating to open.

[0052] In some embodiments, the operator can press or hold the handheld clamp to separate the blowing device and the detection device, and place the mesh A to be tested in a flat posture between the blowing device and the detection device; release the handheld clamp to close the blowing device and the detection device; the structure in which the inner diameter and outer diameter of the first shell 211 and the second shell 221 match can make the edge of the mesh A to be tested subjected to friction, and the friction is converted into a pulling force from the center to the outside of the mesh A to be tested, so that the mesh A to be tested is evenly pressed, automatically flattened and tightened; this structure can ensure that the blowing device and the detection device fit tightly with the mesh A to be tested without leaving any gaps, thereby improving the accuracy of the mesh detection device.

[0053] In some embodiments, as Figure 3 As shown, the mesh detection device further includes an analyzer 300, which is communicatively connected to the airflow inspection equipment.

[0054] Analyzer 300 is an instrument that analyzes data acquired by the various devices of the mesh testing device to accurately determine the air permeability of the mesh under test. Analyzer 300 can obtain the set wind speed of the air blowing device 210 and the wind speed detected by the detection device 220 passing through the mesh under test, and through calculation, determine the air permeability of the mesh under test. For example, as previously mentioned, if the air blowing device 210 and the detection device 220 have the same structure, the detection device 220 can receive changes in the voltage signal caused by the passive rotation of the detection device 220. The analyzer determines the magnitude and change in wind speed due to the passive rotation based on these changes in the voltage signal. Through analysis and calculation, the analyzer determines the pressure difference across the mesh under test, thereby determining the air permeability of the mesh under test.

[0055] The analyzer and the airflow testing device can be connected to each other via a network connection to exchange data and / or information. The network can be any one or more of a wired network and a wireless network. In some embodiments, the analyzer is further provided with a screen capable of displaying or displaying test data and test results in real time.

[0056] In some embodiments of this specification, the analyzer can accurately analyze the air permeability of the mesh to be tested by analyzing the data of the blowing device 210 and the detection device 220; by displaying the test data and test results in real time, the operator can view the data in real time, thereby improving the convenience of the mesh testing device.

[0057] In some embodiments, as Figure 3 As shown, the analyzer 300 is connected to the airflow test device via a connecting line 310. The connecting line 310 refers to a wire or cable used to exchange data or provide power. The connection through the connecting line can improve the stability of data transmission, thereby improving the reliability of the test results.

[0058] In some embodiments, as Figure 3 As shown, the mesh detection device also includes a limit buckle 400. The limit buckle 400 refers to a component that further clamps the blowing device and the detection device, thereby limiting the relative position of the blowing device and the detection device. In some embodiments, the limit buckle 400 includes a male buckle and a female buckle, which are respectively provided on the blowing device and the detection device, and the male buckle and the female buckle are snap-connected. For example, the male buckle is an elastic protrusion provided on the blowing device, and the female buckle is a groove provided on the detection device, and the elastic protrusion is snapped into the groove to limit the position; for another example, the male buckle is an L-shaped hook provided on the blowing device, and the female buckle is a groove or protrusion provided on the detection device, and the L-shaped hook hooks the protrusion or snaps into the groove, thereby snapping the connection.

[0059] In some embodiments of this specification, by providing a limit buckle, the blowing device and the detection device can be further clamped, and when the blowing device or the detection device vibrates or generates strong wind force, the poor accuracy caused by test leakage can be avoided.

[0060] In some embodiments of the present specification, a handheld clamp and an airflow inspection device can be used to make the mesh detection device miniaturized, low-cost, easy to carry and easy to operate; by designing the structure of the detection device and the air blowing device, the mesh to be tested can be fitted with the detection device and the air blowing device, thereby improving the test accuracy.
