Description

Technical Field

[0001] The utility model relates to the technical field of air leakage detection of inflatable products, in particular to an air leakage detection cover structure of an inflatable product. Background Art

[0002] Common inflatable products on the market, such as inflatable beds, inflatable tables, inflatable boats, inflatable toys, etc., are widely favored by consumers due to their advantages such as light weight, foldability, easy to carry, and good comfort. They have a very wide range of applications and have become one of the must-have products for people at home and traveling, with extremely high market prospects. The air tightness of inflatable products is a key indicator for judging the product quality of inflatable products. Whether the air tightness is excellent directly affects consumers' experience of using inflatable products. Therefore, most inflatable products will be tested for air tightness before being put on the market.

[0003] Gas detection is one of the most commonly used air tightness detection methods, and the most widely used gas detection method is helium detection. Existing helium detection devices usually include a test hood and a helium mass spectrometer, wherein a plurality of detection holes are arranged in the test hood, and these detection holes are connected to the helium mass spectrometer pipeline. At the same time, a control valve is also arranged on the pipeline to enable each detection hole to be connected to the helium mass spectrometer in sequence. After filling the inflatable product with helium, the inflatable product is placed in the test hood and sealed. If there is a leak in the inflatable product, the helium mass spectrometer will detect the helium and can roughly determine the location of the leak.

[0004] In order to save the cost of testing equipment, a set of testing devices usually does not only perform air tightness testing on a single inflatable product. For inflatable beds, there are also differences in width, length, and thickness, while the specifications of the test cover are fixed. Therefore, different inflatable products have different distances from the surface to the detection hole. Some detection holes are far away from the surface of the inflatable product. If there is a leak here, the helium leaked from the detection hole directly opposite the leak position when connected to the helium mass spectrometer may not reach the detection hole and be undetected. In order to avoid this situation, the inflatable product can only be placed in the test cover for a period of time and the connection time of each control valve is extended. In general, a single test takes a long time and the detection efficiency is relatively low. In addition, when some of the specifications of the inflatable product are similar to those of the test cover, for example, when the thickness of the inflatable bed is close to the width of the inner cavity of the test cover, the surface of the inflatable bed may be against the inner wall of the test cover, resulting in the blocking of the detection hole, which in turn leads to the appearance of a detection blind spot. Utility Model Content

[0005] The utility model aims to provide an inflatable product leakage detection cover structure, which can be suitable for air tightness detection of inflatable products of different specifications and can ensure a faster detection speed.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A gas leakage detection cover structure for inflatable products comprises a cover body, wherein a detection cavity for accommodating the inflatable product is provided in the cover body; N detection areas are provided on the cover surface of the cover body, N≥2; a plurality of detection holes are arranged in the detection area, each of the detection holes is correspondingly provided with a hose, one end of the hose passes through the detection hole and extends into the detection cavity, and the hose is sealedly connected to the detection hole, and the other end of the hose is connected to an external gas leakage detection device.

[0008] Through the above arrangement, one end of the hose is connected to the external air leakage detection device, and the other end of the hose extends into the detection cavity. When the specifications of the inflatable product are smaller than the mask body, the hose mouth can also be close to or approach the surface of the inflatable product. If there is air leakage in the area near the hose mouth, it can be detected more quickly. When the specifications of the inflatable product are close to the mask body, the hose can be bent, and the hose mouth is not easily blocked by the inflatable product, which can ensure the reliability of the detection.

[0009] The end of the hose extending into the detection cavity is arranged obliquely relative to the cover surface of the cover body, or the end of the hose extending into the detection cavity is arranged in an arc shape. Through the above arrangement, the end of the hose extending into the detection cavity can be better adapted to inflatable products of different specifications, and the pipe opening of the hose is less likely to be blocked by the inflatable product.

[0010] The distance between the pipe opening of the end of the hose extending into the detection cavity and the cover surface of the cover body is 1-10 cm. Through the above arrangement, it can be ensured that the end of the hose extending into the detection cavity can better adapt to inflatable products of different specifications.

[0011] It also includes a manifold that is arranged in one-to-one correspondence with the detection areas, and one end of all the hoses placed outside the cover is connected to the manifold, and the hoses are connected to the external air leakage detection equipment through the manifold. By setting the manifold, the detection points (the pipe openings at one end of the hoses extending into the detection cavity) in the same detection area can be collected for detection, thereby improving the detection efficiency.

[0012] The collector is connected to the cover body. Such an arrangement can ensure the connection between the collector and the hose, and the hose is not easy to fall off.

[0013] After adopting the above solution, by connecting one end of the hose to the external air leakage detection device and extending the other end of the hose into the detection cavity, when the specifications of the inflatable product are smaller than the mask body, the hose mouth can also be close to or approach the surface of the inflatable product, and if there is air leakage in the area near the hose mouth, it can be detected more quickly. When the specifications of the inflatable product are close to the mask body, the hose can be bent, and the hose mouth is not easily blocked by the inflatable product, which can ensure the reliability of the detection.

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0021] like Figure 1-2 As shown, the utility model discloses a gas leakage detection cover structure for inflatable products, which includes a cover body 10, in which a detection cavity 11 for accommodating an inflatable product 20 is provided, and the detection cavity 11 can accommodate inflatable products 20 of various specifications. N detection areas are provided on the cover surface of the cover body 10, and N ≥ 2. In this case, the cover body 10 is in the shape of a wall, and only four detection areas are provided on the two largest side walls of the cover body 10, respectively. Of course, detection areas can be provided on the other two side walls and the top surface of the cover body 10, and adaptive adjustments can be made according to the actual detection products.

[0022] Each detection area is provided with a plurality of detection holes, and each detection area is provided with a collector 12, and each detection hole is provided with a hose 13. One end of the hose 13 (hereinafter defined as the detection end of the hose 13) passes through the detection hole and extends into the detection cavity 11. The gap between the hose 13 and the detection hole is sealed, and can be sealed with a sealant. The other end of the hose 13 is connected to an external air leakage detection device through the collector 12. It is preferred that the collector 12 is connected to the cover body 10 to consolidate the connection between the hose 13 and the collector 12, and the hose 13 is less likely to fall off.

[0023] Through the above arrangement, when the specifications of the inflatable product 20 in the detection cavity 11 are smaller than the mask body 10, the mouth of the hose 13 can also be close to or approach the surface of the inflatable product 20. If there is a leak in the area near the mouth of the hose 13, it can be detected more quickly. When the specifications of the inflatable product 20 are close to the mask body 10, the hose 13 can be bent, and the mouth of the hose 13 is not easily blocked by the inflatable product 20, which can ensure the reliability of the detection. By setting the manifold 12, the detection points in the same detection area (the mouth of the hose 13 at one end of the detection cavity 11) can be combined for detection, thereby improving the detection efficiency. Of course, the manifold 12 is not provided, and the hose 13 can be directly connected to the external leakage detection equipment.

[0024] Preferably, the detection end of the hose 13 is tilted relative to the cover surface of the mask body 10, or the detection end of the hose 13 is arc-shaped, so that the end of the hose 13 extending into the detection cavity 11 can better adapt to inflatable products 20 of different specifications, and the pipe opening of the hose 13 is less likely to be blocked by the inflatable product 20. In addition, the distance between the pipe opening of the detection end of the hose 13 and the cover surface of the mask body 10 is preferably 1-10 cm, so as to ensure that the end of the hose 13 extending into the detection cavity 11 can better adapt to inflatable products 20 of different specifications.

[0025] The key point of the utility model is that by connecting one end of the hose 13 to the external air leakage detection device, and the other end of the hose 13 is inserted into the detection cavity 11, when the size of the inflatable product 20 is smaller than the mask body 10, the pipe mouth of the hose 13 can also be close to or approach the surface of the inflatable product 20, and if there is air leakage in the area near the pipe mouth of the hose 13, it can be detected more quickly. When the size of the inflatable product 20 is close to the mask body 10, the hose 13 can be bent, and the pipe mouth of the hose 13 is not easily blocked by the inflatable product 20, which can ensure the reliability of the detection.

[0026] The above description is only an embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
