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 an important test in the field of materials science and is widely used in the evaluation of packaging materials. Gas permeability testing devices are usually used to determine the permeability of materials to gases and other media, including but not limited to differential pressure method and equal pressure method. The test principle is to use a sample to separate the test chamber into an upper chamber and a lower chamber, where the upper chamber is filled with test gas, and the lower chamber is connected to a gas sensor to monitor the gas permeation in real time, thereby evaluating the gas permeability of the sample.

[0003] Traditional permeability test devices are mainly divided into two types: single-chamber and multi-chamber, according to the number of test chambers. Single-chamber equipment can only test a single sample, which limits the efficiency of the test. Multi-chamber equipment can test multiple gases and other media on the sample at the same time, which significantly improves the efficiency of the test. However, the insufficient sealing performance between the test chambers will have an adverse effect on the accuracy of the test results.

DETAILED DESCRIPTION

[0040] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0041] See also Figure 1 The penetration test structure 10 in one embodiment of the application can at least improve the sealing effect and avoid increasing the complexity of the structure. The penetration test structure 10 includes a detection body 100 and a penetration body 200. The sample to be tested is arranged 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 transmittance of the sample to be tested is detected.

[0042] See also 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, and the second detection chamber 120 is provided on the outer side of the first detection chamber 110, and at least two annular isolation grooves 130 are formed between the first detection chamber 110 and the second detection chamber 120, and an annular isolation groove 130 is also provided on the outer side of the second detection chamber 120 and is spaced from the second detection chamber 120, and the annular isolation groove 130 is used to pass a sealing medium. The annular isolation groove 130 can achieve sealing and isolation of the first detection chamber 110 and the second detection chamber 120.

[0043] See also Figure 8 and Fig. 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, and the second permeation cavity 220 is provided on the outer side of the first permeation cavity 210, and at least two annular sealing grooves 230 are formed between the first permeation cavity 210 and the second permeation cavity 220, and an annular sealing groove 230 is also provided on the outer side of the second permeation cavity 220 and is spaced from the second permeation cavity 220. By providing the annular sealing groove 230, the first permeation cavity 210 and the second permeation cavity 220 can be sealed and isolated. When the permeation body 200 is provided on the detection body 100, the first permeation cavity 210 is opposite to the first detection cavity 110, and the second permeation cavity 220 is opposite to the second detection cavity 120, and each annular isolation groove 130 is correspondingly opposite to an annular sealing groove 230. In this embodiment, the number of the annular isolation grooves 130 and the number of the annular sealing grooves 230 may be the same or different.

[0044] When in use, the sample to be tested is set 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, so that the permeability test of the two test media can be simultaneously performed 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 introduced with sealing media, and the annular isolation groove 130 located on the inner side can isolate and protect the first detection chamber 110, and the annular isolation groove 130 on the outer side and the annular isolation groove 130 on the outer side of the second detection chamber 120 can isolate and protect the second detection chamber 120, effectively realizing the sealed isolation of the first detection chamber 110 and the second detection chamber 120. At the same time, the flowing sealing medium can be effectively filled into each position of the annular isolation groove 130. If the sample is deformed at the position where the annular sealing groove 230 is opposite to the annular isolation groove 130, the flowing sealing medium can also adapt to the deformation of the sample to seal. Moreover, the flowing sealing medium can form a certain pressure area in the annular sealing groove 230 to prevent gas leakage in the first detection cavity 110 and the second detection cavity 120.

[0045] 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 area 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, which facilitates the statistics of subsequent test results. In other embodiments, the areas of the first detection chamber 110 and the second detection chamber 120 may not be consistent, and 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.

[0046] In one embodiment, the number of the second detection chambers 120 is one, two or more. When the number of the second detection chambers 120 is two or more, each second detection chamber 120 is radially spaced with the first detection chamber 110 as the center, and at least two annular isolation grooves 130 are formed between two adjacent second detection chambers 120. The number of second permeation chambers 220 is consistent with the number of second detection chambers 120, and each second permeation chamber 220 can correspond to a second detection chamber 120. The number of annular sealing grooves 230 is greater than or equal to the number of annular isolation grooves 130, and each annular isolation groove 130 can correspond to an annular sealing groove 230. The number of the second detection chamber 120 of the present application is one, and the first detection chamber 110 and the second detection chamber 120 are used for the detection of oxygen and water vapor respectively. In other embodiments, the number of the second detection chambers 120 can be two or more. By setting more second detection chambers 120, more test media can be tested synchronously, further improving the 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.

[0047] See also Figure 1 and Figure 7 In one embodiment, the two opposite 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, and an air intake docking area and an exhaust docking area are formed on the mounting surface 102, the number of the air intake docking area and the number of the exhaust docking area are consistent with the number of the detection cavities, and are both arranged at intervals. By arranging the air intake docking area and the exhaust docking area on the mounting surface 102 of the detection body 100, it is convenient to realize the air intake or exhaust of the first detection cavity 110 and the second detection cavity 120 from the same side, and improve the convenience of installing and docking the air intake and exhaust pipelines.

[0048] See also 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.

[0049] Specifically, a first exhaust channel 114 is also formed in the detection body 100, one end of the first exhaust channel 114 is connected to the first detection chamber 110, and the other end of the first exhaust channel 114 is connected to an exhaust docking area. The first air intake channel 112 is used to intake air into the first detection chamber 110, and the first exhaust channel 114 is used to discharge gas in the first detection chamber 110, and the isobaric method can be used to perform transmittance detection on the sample. In other embodiments, the first exhaust channel 114 can be omitted, so that the first detection chamber 110 can perform transmittance detection on the sample using the differential pressure method.

[0050] Furthermore, the positions where the first air inlet channel 112 and the first exhaust channel 114 are connected to the first detection chamber 110 are arranged symmetrically 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 in the first detection chamber 110 and then discharged through the first exhaust channel 114. Furthermore, the lengths of the first air inlet channel 112 and the first exhaust channel 114 are the same. Through the symmetrical arrangement structure, when in use, one of the channels can be selected as the first air inlet channel 112 and the other channel as the first exhaust channel 114, thereby improving the convenience of use.

[0051] See also 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.

[0052] Specifically, a second exhaust channel 124 is formed in the detection body 100, one end of the second exhaust channel 124 is connected to the second detection chamber 120, and the other end of the second exhaust channel 124 is connected to another exhaust docking area. The second air intake channel 122 is used to intake air into the second detection chamber 120, and the second exhaust channel 124 is used to discharge gas from the second detection chamber 120. In the second detection chamber 120, the isobaric method can be used to perform transmittance detection on the sample. In other embodiments, the second exhaust channel 124 can be omitted, so that the second detection chamber 120 can perform transmittance detection on the sample using the differential pressure method.

[0053] Furthermore, the positions where the second air inlet channel 122 and the second exhaust channel 124 are connected to the second detection chamber 120 are arranged symmetrically relative to the second detection chamber 120. When the test medium enters the second detection chamber 120 from the second air inlet channel 122, it is convenient to be uniformly diffused in the second detection chamber 120 and then discharged. Furthermore, the lengths of the second air inlet channel 122 and the second exhaust channel 124 are the same. When in use, one channel can be selected as the second air inlet channel 122 and the other channel as the second exhaust channel 124 to improve the convenience of use.

[0054] 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, and 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 circulating 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.

[0055] In other embodiments, the permeation body 200 may also be formed with a protective air inlet channel and a protective air exhaust channel, both of which are connected to 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 possibility of gas leakage is reduced by introducing protective gas. Specifically, the annular sealing grooves 230 may be partially connected in series, or not connected in series at all, and protective gas may be introduced into each annular sealing groove 230.

[0056] See also 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 in the detection body 100, and the number of the sealed air inlet channels 131 and the sealed air exhaust channels 132 is the same; wherein, the number of the sealed air inlet channels 131 and the sealed air exhaust channels 132 are both one, and each annular isolation groove 130 is connected in series through 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, and 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 each annular isolation groove 130 in series, it is only necessary to control the sealing medium to enter through a sealed air inlet channel 131 and to be discharged through a sealed air exhaust channel 132.

[0057] In another embodiment, the number of sealed air inlet channels 131 and sealed air exhaust channels 132 are both two, wherein two annular isolation grooves 130 are connected through a series channel 133, wherein one end of a sealed air inlet channel 131 and one end of a sealed air exhaust channel 132 are respectively connected to the two annular isolation grooves 130 connected in series, one end of another sealed air inlet channel 131 and one end of another sealed air exhaust channel 132 are connected to another annular isolation groove 130, the other ends of the two sealed air inlet channels 131 are respectively connected to two air inlet docking areas or are both 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 are both 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, so as to facilitate simultaneous docking of the air inlet pipeline joints; the same applies to the air exhaust. For example, in this embodiment, there are two intake docking areas and two exhaust docking areas, so the number of sealed intake channels 131 and sealed exhaust channels 132 is less than or equal to two, so as to avoid increasing the intake and exhaust docking areas due to the need to pass the sealing medium through the annular isolation groove 130.

[0058] Specifically, the two annular isolation grooves 130 adjacent to the second detection cavity 120 are connected via a series channel 133 , so that the inner and outer sides of the second detection cavity 120 are isolated and sealed by using the same sealing medium.

[0059] In this embodiment, the position where the sealed air inlet channel 131 is connected to the annular isolation groove 130 and the position where the sealed air exhaust channel 132 is connected to the annular isolation groove 130 are arranged symmetrically with respect to the annular isolation groove 130. When the sealing medium enters the annular isolation groove 130, it can be discharged after uniform diffusion, so that the sealing medium effectively fills the annular isolation groove 130.

[0060] In other embodiments, a sealed air inlet channel 131 and a sealed air exhaust channel 132 may be connected to each annular isolation groove 130. Alternatively, some of the annular isolation grooves 130 may be connected in series. The number of sealed air inlet channels 131 may be less than or equal to the number of air inlet docking areas, and the number of sealed air exhaust channels 132 may be less than or equal to the number of air exhaust docking areas.

[0061] See also 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 arranged in the air intake docking groove 141, a first air intake hole 144 is opened in the air intake portion 142, the air intake ring 143 is sleeved outside the air intake portion 142 and spaced from the air intake portion 142, and a second air intake hole 145 is opened on the air intake ring 143. The sealed air intake channel 131 is communicated with one of the first air intake hole 144 and the second air intake hole 145, and the first air intake channel 112 or the second air intake channel 122 is communicated with the other of the first air intake hole 144 and the second air intake hole 145.
