DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Please refer to Figure 1. An embodiment of the present invention provides a liquid leakage detection tape, including a base tape 10 and a first liquid leakage detection wire 20 and a second liquid leakage detection wire 30 provided on the base tape 10. The base tape 10 can be a flexible tape, and the first liquid leakage detection wire 20 and the second liquid leakage detection wire 30 can be formed on the base tape 10 by electroplating. The shape of the base tape 10 can be a long strip. The first liquid leakage detection wire 20 and the second liquid leakage detection wire 30 can be provided on the base tape 10 in a straight manner, that is, the first liquid leakage detection wire 20 and the second liquid leakage detection wire 30 extend along the length direction of the base tape 10; the first liquid leakage detection wire 20 and the second liquid leakage detection wire 30 can be arranged in a continuous bending manner or in the form of a wavy line. The first leakage detection wire 20 and the second leakage detection wire 30 are spaced apart by a preset distance. When liquid leaking from the liquid cooling device falls and contacts the first leakage detection wire 20 and the second leakage detection wire 30 simultaneously, the first leakage detection wire 20 and the second leakage detection wire 30 are short-circuited, thereby realizing the leakage detection function. The leakage detection tape can be applied to leakage detection of infusion pipelines, and can also be applied to leakage detection of other structures of liquid cooling devices. Importantly, the first leakage detection wire 20 is provided with a first leakage detection tab 21, and the second leakage detection tab 31 is provided with a second leakage detection tab 31. The first leakage detection tab 21 is located at the same position along the length of the first leakage detection wire 20 as the second leakage detection tab 31 is located along the length of the second leakage detection wire 30. For example, as shown in FIG1 , the distance between the first leakage detection tab 21 and the left end of the baseband 10 is the same as the distance between the second leakage detection tab 31 and the left end of the baseband 10. The baseband 10, the first leakage detection wire 20, and the second leakage detection wire 30 can be cut along the first leakage detection tab 21 and the second leakage detection tab 31. The purpose of providing the first leakage detection tab 21 and the second leakage detection tab 31 is to increase the wiring area to facilitate wiring after cutting. Preferably, the width of the first leakage detection tab 21 is greater than the width of the first leakage detection wire 20, and the width of the second leakage detection tab 31 is greater than the width of the second leakage detection wire 30. When a shorter length of the leak detection tape is required, it can be cut from the first leak detection tab 21 and the second leak detection tab 31. When a longer length of the leak detection tape is required, a section of the leak detection tape can be connected to the cut-off position of the first leak detection tab 21 and the second leak detection tab 31. Therefore, the leak detection tape of the required length can be cut or connected according to the length of the infusion pipeline, thereby effectively improving the adaptability of the leak detection tape to the infusion pipeline. The first leak detection wire 20 and the second leak detection wire 30 can be provided with multiple sets of cut-off structures of the first leak detection tab 21 and the second leak detection tab 31. The multiple sets of cut-off structures can be evenly or unevenly distributed along the length of the base tape 10.

[0028] In some embodiments, the first and second leakage detection contacts 21 and 31 extend toward each other. As shown in FIG1 , the first and second leakage detection contacts 21 and 31 are disposed opposite each other, with a predetermined spacing therebetween. When liquid leakage simultaneously contacts the first and second leakage detection contacts 21 and 31, the first and second leakage detection wires 20 and 30 are electrically conductive and short-circuited. Alternatively, the first and second leakage detection contacts 21 and 31 may extend away from each other.

[0029] In some embodiments, as shown in Figure 3, the leakage detection strip also includes a first connector 70, and a first connecting wire 71 and a second connecting wire 72 are provided on the first connector 70. The first connecting wire 71 can be connected to the cut first leakage detection contact 21, and the second connecting wire 72 can be connected to the cut second leakage detection contact 31. In order to improve the convenience of the first connector 70 for connecting the two cut sections of the leakage detection strip, the first connector 70 is also provided with two first wire contacts respectively connected to the two ends of the first connecting wire 71, and two second wire contacts respectively connected to the two ends of the second connecting wire 72. When connecting, the two first wire contacts are respectively in contact with the first leakage detection contacts 21 of the two leakage detection strips to be connected, and the two second wire contacts are respectively in contact with the two second leakage detection contacts 31. Due to the surface-to-surface contact relationship, the convenience of connecting the strips can be effectively improved.

[0030] In some embodiments, as shown in Figure 2, the first liquid leakage detection contact 21 includes two first tapping pieces 211 spaced apart along the length direction of the first liquid leakage detection wire 20, wherein the two first tapping pieces 211 are adjacently distributed, and the sizes of the two first tapping pieces 211 are preferably the same, and the area between the two first tapping pieces 211 can be cut off. The second liquid leakage detection contact 31 includes two second tapping pieces 311 spaced apart along the length direction of the second liquid leakage detection wire 30, wherein the two second tapping pieces 311 are adjacently distributed, and the sizes of the two second tapping pieces 311 are preferably the same, and the area between the two second tapping pieces 311 can be cut off. When the leakage detection tape needs to be cut, the base tape 10, the first leakage detection wire 20, and the second leakage detection wire 30 can be cut between the two first tapping pieces 211 and the two second tapping pieces 311. As shown in FIG2 , the leakage detection tape can be cut between the two first tapping pieces 211 and the two second tapping pieces 311 in a direction perpendicular to the base tape 10. In this embodiment, the first leakage detection tab 21 and the second leakage detection tab 31 are each designed as a two-piece structure, which makes it easier for the user to cut the leakage detection tape and avoids the problem of the first leakage detection tab 21 and the second leakage detection tab 31 on one section having a smaller area and the first leakage detection tab 21 and the second leakage detection tab 31 on the other section having a larger area after the leakage detection tape is cut.

[0031] In some embodiments, a cutoff indicator line 40 is provided on the base tape 10. The cutoff indicator line 40 can be an indentation or a drawn line, for example, a line of a color that is easily identifiable and distinct from the base tape 10, the first leakage detection wire 20, the first leakage detection tab 21, the second leakage detection wire 30, and the second leakage detection tab 31. The cutoff indicator line 40 passes through the first leakage detection wire 20, the first leakage detection tab 21, the second leakage detection wire 30, and the second leakage detection tab 31. When the leakage detection tape needs to be cut, the user can cut along the cutoff indicator line 40, thereby avoiding the problem of misaligned cutting and making it easier for the user to find the cutting position, thereby improving cutting efficiency.

[0032] In some embodiments, at least one first detection sheet 22 is provided on one side of the first leakage detection wire 20, extending toward the second leakage detection wire 30, and / or at least one second detection sheet 32 ​​is provided on one side of the second leakage detection wire 30, extending toward the first leakage detection wire 20. The detection sheets of the leakage detection strip can be distributed in three ways: the first detection sheet 22 is provided on one side of the first leakage detection wire 20; the second detection sheet 32 ​​is provided on one side of the second leakage detection wire 30; and the third detection sheet 22 is provided on one side of the first leakage detection wire 20, and the second detection sheet 32 ​​is provided on one side of the second leakage detection wire 30. In this arrangement, the first detection sheet 22 and the second detection sheet 32 ​​do not contact each other; the first detection sheet 22 and the second leakage detection wire 30 do not contact each other, and the second detection sheet 32 ​​and the first leakage detection wire 20 do not contact each other. During detection, when the leaked liquid contacts the first detection piece 22 and the second detection piece 32 at the same time, or contacts the first detection piece 22 and the second leakage detection wire 30 at the same time, or contacts the second detection piece 32 and the first leakage detection wire 20 at the same time, or contacts the first leakage detection wire 20 and the second leakage detection wire 30 at the same time, a leakage problem can be detected. Therefore, compared with the existing method of performing leakage detection only through the first leakage detection wire 20 and the second leakage detection wire 30, the leakage detection accuracy can be effectively improved.

[0033] In some embodiments, the first detection piece 22 and the second detection piece 32 are staggered and spaced apart with a predetermined distance between them. As shown in FIG1 , the first detection piece 22 and the second detection piece 32 are arranged in a comb-like pattern. The width of the first detection piece 22 and the second detection piece 32 can be greater than, less than, or equal to half the distance between the first leakage detection wire 20 and the second leakage detection wire. It should be noted that the first detection piece 22 and the second detection piece 32 shown in FIG1 and FIG2 are rectangular structures. In addition, other shapes such as triangles, trapezoids, L-shapes, or T-shapes are also possible. As long as the first detection piece 22 protrudes toward the second leakage detection wire 30, and the second detection piece 32 protrudes toward the first leakage detection wire 20, it is sufficient.

[0034] In some embodiments, the leakage detection strip further includes a first disconnection detection wire 50 and a second disconnection detection wire 60 provided on the base strip 10, one end of the first disconnection detection wire 50 is connected to one end of the first leakage detection wire 20, and one end of the second disconnection detection wire 60 is connected to one end of the second leakage detection wire 30. During normal detection, when the first leakage detection wire 20 is not disconnected, current will pass through the first disconnection detection wire 50. When the first leakage detection wire 20 is disconnected, no current will pass through the first disconnection detection wire 50. Similarly, when the second leakage detection wire 30 is disconnected, no current will pass through the second disconnection detection wire 60. Therefore, through the first disconnection detection wire 50 and the second disconnection detection wire 60, it can be determined whether the first leakage detection wire 20 and the second leakage detection wire 30 are disconnected, so as to facilitate timely maintenance to prevent disconnections that cannot be discovered in time, thereby effectively improving the detection accuracy of the leakage detection strip.

[0035] In some embodiments, as shown in Figures 1 and 2, a first disconnection detection contact 51 is provided on the first disconnection detection wire 50, and the first end of the first disconnection detection wire 50 is flush with the first end of the first leakage detection wire 20. The distance between the first disconnection detection contact 51 and the first end of the first disconnection detection wire 50 is the same as the distance between the first leakage detection contact 21 and the first end of the first leakage detection wire 20; a second disconnection detection contact 61 is provided on the second disconnection detection wire 60, and the first end of the second disconnection detection wire 60 is flush with the first end of the second leakage detection wire 30. The distance between the first end of the second disconnection detection contact 61 and the first end of the second disconnection detection wire 60 is the same as the distance between the second leakage detection contact 31 and the first end of the second leakage detection wire 30. The first end of the first leakage detection wire 20, the first end of the second leakage detection wire 30, the first end of the first disconnection detection wire 50, and the first end of the second disconnection detection wire 60 are the same end, such as the left end or the right end as shown in Figure 1. The first disconnection detection contact 51 can increase the wiring area of ​​the first disconnection detection wire 50, thereby facilitating connection of the first disconnection detection wire 50. The second disconnection detection contact 61 can increase the wiring area of ​​the second disconnection detection wire 60, thereby facilitating connection of the second disconnection detection wire 60. As shown in FIG1 , the first disconnection detection wire 50 is located outside the first leakage detection wire 20, and the second disconnection detection wire 60 is located outside the second leakage detection wire 30. The first disconnection detection contact 51 extends away from the first leakage detection wire 20, and the second disconnection detection contact 61 extends away from the second leakage detection wire 30. As shown in Figure 2, the first disconnection detection contact 51 includes two first disconnection detection tapping pieces 511 spaced apart along the length direction of the first disconnection detection wire 50, and the second disconnection detection contact 61 includes two second disconnection detection tapping pieces 611 spaced apart along the length direction of the second disconnection detection wire 60. The leakage detection belt can be cut between the two first disconnection detection tapping pieces 511 and between the two second disconnection detection tapping pieces 611.

[0036] In some embodiments, the leakage detection strip further includes a second connector 80, which is provided with a first end connecting wire 81 and a second end connecting wire 82. One side of the second connector 80 is provided with a first wire break detection wire end tab 83, a first wire break detection wire end tab 84, and a second wire break detection wire end tab 85 and a second wire break detection wire end tab 86. The ends of the first end connecting wire 81 are respectively connected to the first wire break detection wire end tab 83 and the first wire break detection wire end tab 84, while the ends of the second end connecting wire 82 are respectively connected to the second wire break detection wire end tab 85 and the second wire break detection wire end tab 86. For a truncated leakage detection strip, one end of the strip can be connected to another strip via the first connector 70, while the other end is connected to the second connector 80. The first disconnection detection wire end contact 83 contacts the first disconnection detection contact 51 , the first leakage detection wire end contact 84 contacts the first leakage detection contact 21 , the second leakage detection wire end contact 85 contacts the second leakage detection contact 31 , and the second disconnection detection wire end contact 86 contacts the second disconnection detection contact 61 , thereby achieving the connection between the first leakage detection wire 20 and the first disconnection detection wire 50 , and the connection between the second leakage detection wire 30 and the second disconnection detection wire 60 .
