Description

Technical Field

[0001] The present application relates to the technical field of detection equipment, and in particular to a penetration test structure and a penetration tester. Background Art

[0002] Gas permeability testing is a key test in materials science, widely used in the evaluation of packaging materials and other applications. Gas permeability testing equipment is typically used to determine a material's permeability to gases and other media, including but not limited to differential pressure and equal pressure methods. The test principle involves using a test specimen to separate the test chamber into an upper chamber and a lower chamber. The upper chamber is filled with the test gas, while the lower chamber is connected to a gas sensor for real-time monitoring of gas permeation, thereby evaluating the sample's gas permeability.

[0003] Traditional permeability testers are primarily categorized into single-chamber and multi-chamber types, depending on the number of test chambers. Single-chamber devices can only test a single sample, limiting test efficiency. Multi-chamber devices can simultaneously test a sample with multiple gases and other media, significantly improving test efficiency. However, insufficient sealing between test chambers can negatively impact the accuracy of test results. Improving sealing performance often requires increasing structural complexity, which in turn increases manufacturing costs. Utility Model Content

DETAILED DESCRIPTION

[0042] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0043] See Figure 1 The penetration test structure 10 of one embodiment of the present invention can at least improve the sealing effect and avoid increasing the structural complexity. The penetration test structure 10 includes a detection body 100 and a penetration body 200. The sample to be tested is placed between the detection body 100 and the penetration body 200. By passing the test medium through one side of the detection body 100, the test medium's transmittance of the sample to be tested is tested.

[0044] See Figure 1 and Figure 2 Specifically, the detection body 100 is provided with a first detection chamber 110 and a second detection chamber 120. The second detection chamber 120 is an annular groove disposed on the outer side of the first detection chamber 110. At least two annular isolation grooves 130 are formed between the first and second detection chambers 110, 120. An annular isolation groove 130 is further disposed outside the second detection chamber 120, spaced apart from the second detection chamber 120. The annular isolation grooves 130 are used to pass a sealing medium. The annular isolation grooves 130 seal and isolate the first and second detection chambers 110, 120.

[0045] See Figure 8 and Figure 9 Specifically, the permeation body 200 is provided with a first permeation cavity 210 and a second permeation cavity 220. The second permeation cavity 220 is an annular groove disposed on the outer side of the first permeation cavity 210. At least two annular sealing grooves 230 are formed between the first and second permeation cavities 210 and 220, respectively. An annular sealing groove 230 is also disposed on the outer side of the second permeation cavity 220, spaced apart from the second permeation cavity 220. The provision of the annular sealing grooves 230 enables sealing and isolation between the first and second permeation cavities 210 and 220. When the permeation body 200 is disposed on the detection body 100, the first permeation cavity 210 faces the first detection cavity 110, and the second permeation cavity 220 faces the second detection cavity 120. Each annular isolation groove 130 corresponds to an annular sealing groove 230. In this embodiment, the number of annular isolation grooves 130 and annular sealing grooves 230 may be the same or different.

[0046] During use, the sample to be tested is placed between the permeation body 200 and the detection body 100, and then different test media can be introduced into the first detection chamber 110 and the second detection chamber 120 respectively. The test medium in the first detection chamber 110 can penetrate into the first permeation chamber 210 through the sample, and the test medium in the second detection chamber 120 can penetrate into the second permeation chamber 220 through the sample, thereby simultaneously performing transmittance tests of the two test media on the sample to be tested. Since there are at least two annular isolation grooves 130 spaced apart between the first detection chamber 110 and the second detection chamber 120, the two annular isolation grooves 130 are filled with sealing media. The inner annular isolation groove 130 can isolate and protect the first detection chamber 110, and the outer annular isolation groove 130 and the outer annular isolation groove 130 of the second detection chamber 120 can isolate and protect the second detection chamber 120, effectively achieving sealed isolation between the first detection chamber 110 and the second detection chamber 120. Simultaneously, the flowing sealing medium effectively fills every position within the annular isolation groove 130. If the sample deforms in the position where the annular sealing groove 230 faces the annular isolation groove 130, the flowing sealing medium adapts to the deformation and seals the sample. Furthermore, the flowing sealing medium creates a constant pressure zone within the annular sealing groove 230, preventing gas leakage from the first and second detection cavities 110, 120.

[0047] In one embodiment, the area of ​​the first detection chamber 110 is consistent with the area of ​​the second detection chamber 120. The area of ​​the first permeation chamber 210 is consistent with the area of ​​the second permeation chamber 220. By setting the areas of the first detection chamber 110 and the second detection chamber 120 to be the same, the areas of the two test media to be tested are consistent, facilitating the statistical analysis of subsequent test results. In other embodiments, the areas of the first detection chamber 110 and the second detection chamber 120 may be different, while the cross-sectional shape and size of the first permeation chamber 210 are consistent with those of the first detection chamber 110, and the cross-sectional shape and size of the second permeation chamber 220 are consistent with those of the second detection chamber 120.

[0048] In one embodiment, the number of second detection cavities 120 is one, two, or more. When the number of second detection cavities 120 is two or more, each second detection cavity 120 is radially spaced apart with the first detection cavity 110 as the center, and at least two annular isolation grooves 130 are formed between two adjacent second detection cavities 120. The number of second permeation cavities 220 is the same as the number of second detection cavities 120. Each second permeation cavity 220 can correspond to a second detection cavity 120. The number of annular sealing grooves 230 is greater than or equal to the number of annular isolation grooves 130. Each annular isolation groove 130 can correspond to an annular sealing groove 230. In the present application, the number of second detection cavities 120 is one, and the first detection cavity 110 and the second detection cavity 120 are used for detecting oxygen and water vapor, respectively. In other embodiments, the number of second detection cavities 120 can be two or more. By providing more second detection cavities 120, more test media can be tested simultaneously, further improving detection efficiency. The two adjacent second detection chambers 120 are sealed and isolated by the annular isolation groove 130 to ensure the sealing of the test.

[0049] See Figure 1 and Figure 7 In one embodiment, the two opposing surfaces of the detection body 100 are respectively a test surface 101 and a mounting surface 102. The first detection cavity 110 and the second detection cavity 120 are both formed on the test surface 101. The mounting surface 102 is formed with air intake and exhaust docking areas. The number of these air intake and exhaust docking areas is the same as the number of detection cavities, and they are spaced apart. By providing both the air intake and exhaust docking areas on the mounting surface 102 of the detection body 100, air intake and exhaust of the first detection cavity 110 and the second detection cavity 120 can be facilitated from the same side, improving the convenience of installing and docking the air intake and exhaust pipelines.

[0050] See Figure 3 、 Figure 4 and Figure 7 In one embodiment, a first air inlet channel 112 is formed in the detection body 100 , one end of the first air inlet channel 112 is connected to the first detection cavity 110 , and the other end of the first air inlet channel 112 is connected to an air inlet docking area.

[0051] Specifically, a first exhaust channel 114 is formed within the detection body 100. One end of the first exhaust channel 114 communicates with the first detection chamber 110, and the other end of the first exhaust channel 114 communicates with an exhaust docking area. Air is introduced into the first detection chamber 110 via the first air inlet channel 112, and gas within the first detection chamber 110 is exhausted via the first exhaust channel 114. The transmittance of the sample can be tested using the isobaric method. In other embodiments, the first exhaust channel 114 can be omitted, and the first detection chamber 110 can then perform transmittance testing on the sample using the differential pressure method.

[0052] Furthermore, the positions at which the first air inlet channel 112 and the first exhaust channel 114 communicate with the first detection chamber 110 are symmetrically arranged relative to the first detection chamber 110. After the test medium enters the first detection chamber 110 through the first air inlet channel 112, it can be evenly diffused within the first detection chamber 110 before being discharged through the first exhaust channel 114. Furthermore, the first air inlet channel 112 and the first exhaust channel 114 are of the same length. This symmetrical arrangement allows one channel to be selected as the first air inlet channel 112 and the other as the first exhaust channel 114 during use, improving ease of use.

[0053] See Figure 3 、 Figure 5 and Figure 7 In one embodiment, a second air inlet channel 122 is formed in the detection body 100 , one end of the second air inlet channel 122 is connected to the second detection cavity 120 , and the other end of the second air inlet channel 122 is connected to another air inlet docking area.

[0054] Specifically, a second exhaust channel 124 is formed within the detection body 100. One end of the second exhaust channel 124 communicates with the second detection chamber 120, and the other end of the second exhaust channel 124 communicates with another exhaust docking area. Air is introduced into the second detection chamber 120 via the second air inlet channel 122, and gas within the second detection chamber 120 is exhausted via the second exhaust channel 124. In the second detection chamber 120, the transmittance of the sample can be tested using the isobaric method. In other embodiments, the second exhaust channel 124 can be omitted, in which case the second detection chamber 120 can perform transmittance testing on the sample using the differential pressure method.

[0055] Furthermore, the positions at which the second air inlet channel 122 and the second exhaust channel 124 communicate with the second detection chamber 120 are symmetrically arranged relative to the second detection chamber 120. After the test medium enters the second detection chamber 120 through the second air inlet channel 122, it is evenly diffused within the second detection chamber 120 before being discharged. Furthermore, the second air inlet channel 122 and the second exhaust channel 124 are of the same length. During use, one channel can be selected as the second air inlet channel 122 and the other as the second exhaust channel 124, improving ease of use.

[0056] In one embodiment, a sealing ring is provided in the annular sealing groove 230. A flowing sealing medium, such as a protective gas, is introduced into the annular isolation groove 130. The elasticity of the sealing ring can press against the sample to be tested. The sealing medium can fill the entire space in the annular isolation groove 130 and can press the sample to be tested against the sealing ring under a certain pressure, thereby improving the reliability of the seal. The present application improves the reliability of the seal by introducing a flowing sealing medium, such as a protective gas, on one side and providing a sealing ring on the other side without increasing the complexity of the structure.

[0057] In other embodiments, the permeation body 200 may further include a protective air inlet channel and a protective air exhaust channel, both of which are in communication with the annular sealing groove 230. Protective gas is introduced into the annular sealing groove 230 through the protective air inlet channel. For example, when harmful gas is introduced into the detection chamber or the permeation chamber, the introduction of protective gas reduces the possibility of gas leakage. Specifically, the annular sealing grooves 230 may be partially or completely connected in series, and protective gas may be introduced into each annular sealing groove 230.

[0058] See Figure 3 、 Figure 6 and Figure 7 In one embodiment, a sealed air inlet channel 131, a sealed air exhaust channel 132, and a series channel 133 are formed within the detection body 100. The number of sealed air inlet channels 131 and sealed air exhaust channels 132 is the same; there is only one sealed air inlet channel 131 and one sealed air exhaust channel 132, respectively. Each annular isolation groove 130 is connected in series via the series channel 133. One end of the sealed air inlet channel 131 and one end of the sealed air exhaust channel 132 are respectively connected to the two outermost annular isolation grooves 130 on the series path. The other end of the sealed air inlet channel 131 is connected to one of the air inlet docking areas, and the other end of the sealed air exhaust channel 132 is connected to one of the air exhaust docking areas. By connecting the annular isolation grooves 130 in series, it is only necessary to control the sealing medium to enter through one sealed air inlet channel 131 and to be discharged through one sealed air exhaust channel 132.

[0059] In another embodiment, there are two sealed air inlet channels 131 and two sealed air exhaust channels 132, wherein the two annular isolation grooves 130 are connected via a series channel 133, wherein one end of one sealed air inlet channel 131 and one end of one sealed air exhaust channel 132 are respectively connected to the two annular isolation grooves 130 connected in series, and one end of another sealed air inlet channel 131 and one end of another sealed air exhaust channel 132 are respectively connected to the other annular isolation groove 130, and the other ends of the two sealed air inlet channels 131 are respectively connected to two air inlet docking areas or both are connected to one of the air inlet docking areas, and the other ends of the two sealed air exhaust channels 132 are respectively connected to two air exhaust docking areas or both are connected to one of the air exhaust docking areas. The air inlet of the annular isolation groove 130 and the air inlet of the first detection chamber 110 or the second detection chamber 120 are located in the same area, facilitating simultaneous docking of the air inlet pipe joints; the same applies to the air exhaust. For example, in this embodiment, there are two air intake docking areas and two exhaust docking areas, so the number of sealed air intake channels 131 and sealed exhaust channels 132 is less than or equal to two, so as to avoid increasing the air intake and exhaust docking areas due to the need to pass the sealing medium through the annular isolation groove 130.

[0060] Specifically, the two annular isolation grooves 130 adjacent to the second detection cavity 120 are connected via a series channel 133 , so as to facilitate isolation and sealing of the inner and outer sides of the second detection cavity 120 with the same sealing medium.

[0061] In this embodiment, the position where the sealed air inlet channel 131 communicates with the annular isolation groove 130 and the position where the sealed air exhaust channel 132 communicates with the annular isolation groove 130 are arranged symmetrically relative to the annular isolation groove 130. When the sealing medium enters the annular isolation groove 130, it can be discharged after being evenly diffused, so that the sealing medium effectively fills the annular isolation groove 130.

[0062] In other embodiments, each annular isolation groove 130 may be connected to a sealed inlet channel 131 and a sealed exhaust channel 132. Alternatively, some of the annular isolation grooves 130 may be connected in series. The number of sealed inlet channels 131 may be less than or equal to the number of inlet docking areas, and the number of sealed exhaust channels 132 may be less than or equal to the number of exhaust docking areas.

[0063] See Figure 3 and Figure 7In one embodiment, the air intake docking area is formed with an air intake docking groove 141. An air intake portion 142 and an air intake ring 143 are disposed within the air intake docking groove 141. A first air intake hole 144 is defined within the air intake portion 142. The air intake ring 143 is sleeved around the air intake portion 142 and spaced apart from the air intake portion 142. A second air intake hole 145 is defined within the air intake ring 143. The sealed air intake passage 131 communicates with one of the first air intake hole 144 and the second air intake hole 145, while the first air intake passage 112 or the second air intake passage 122 communicates with the other of the first air intake hole 144 and the second air intake hole 145. Taking one of the air intake docking areas as an example, when the air intake connector is docked in the air intake docking groove 141, the test medium can effectively enter the first air intake channel 112 or the second air intake channel 122, while the sealing medium can also enter the sealed air intake channel 131 through the air intake docking groove 141, thereby improving installation and docking efficiency. In other embodiments, the shape and structure of the air intake docking area can be determined by the shape of the docking air intake connector.

[0064] In one embodiment, the exhaust docking area is formed with an exhaust docking groove 151. An exhaust portion 152 and an exhaust ring 153 are disposed within the exhaust docking groove 151. A first exhaust hole 154 is defined within the exhaust portion 152. The exhaust ring 153 is sleeved over and spaced from the exhaust portion 152, and a second exhaust hole 155 is defined within the exhaust ring 153.
