The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

The embodiment of the invention discloses a sealed-off carbon dioxide laser tube with air leakage detection, which is shown in the attached figures 1-4 and specifically comprises the following components: the laser tube, the body 1 of the laser tube has transparent reaction storehouse 6; the reaction bin 6 can be independently inserted into a reserved position on the pipe body 1, and can also be directly formed in the processing process of the pipe body 1; the reaction chamber 6 is disposed inside or outside the tube 1.

In one embodiment, one end of the reaction bin is fixedly sintered with the inner wall of the gas storage pipe; the reaction bin 6 is communicated with the gas storage pipe 4; the reaction chamber 6 can be communicated with a plurality of air holes 61 communicated with the air storage pipe 4; the reaction chamber 6 can be made of transparent glass, and the shape of the reaction chamber can be cylindrical, rectangular, elliptic cylinder or polygonal; the detection indicating component 7 is arranged in the reaction bin 6, the detection indicating component 7 comprises a carrier and an indicator, the indicator is attached to the carrier, and the carrier is inserted in the reaction bin 6 in parallel. The carrier is fiber paper, and can be in the form of line, belt or sheet, and the indicator can be chemically reacted with oxygen to change its color. The indicator may be pink in the absence of oxygen and blue in the presence of oxygen.

It is worth to be noted that, because the indicator contacts with air in the process of placing the detection indicating component, the indicator is oxidized from pink to blue, and because the deoxidizing and reducing effects of the indicator in the air after short-time exposure in the process of placing the indicator are not affected (within 1 hour), the indicator recovers pink after the gas storage tube is vacuumized and exhausted.

Because the inside negative pressure that is of carbon dioxide laser pipe gas storage tube, oxygen in the air gets into inside the gas storage tube by the leak point, and oxygen in the air and the indicator in the reaction storehouse produce chemical reaction rapidly, make the indicator generate for blue by pink oxidation reaction, form the warning colour, and the user of service can observe this warning information through transparent glass pipe.

Therefore, the method solves the problem that whether the product is air-leakage damaged or not can not be judged visually in the processes of production, debugging, transportation, installation and use of the carbon dioxide laser tube, and can efficiently and accurately assist personnel and equipment in confirming the damaged product. Thereby reducing the economic loss and dispute of the merchant and the user in the processes of production, transportation and use.
