背景技术Background Art
一氧化碳通常状况下为是无色、无臭、无味的气体，一氧化碳具有毒性，较高浓度时能使人出现不同程度中毒症状，由于一氧化碳属于可燃烧气体，为保证一氧化碳的安全使用需要对一氧化碳进行浓度检测。Carbon monoxide is normally a colorless, odorless, tasteless gas. It is toxic and can cause varying degrees of poisoning in humans at higher concentrations. Since carbon monoxide is a combustible gas, concentration testing is required to ensure its safe use.
在公开号为CN219121822U的中国专利中，提到了一种高密封气体取样器，包括取样筒和固定块，所述固定块连通在取样筒的一端，所述固定块远离取样筒的一侧设置有吸嘴，所述取样筒的外表面滑动连接有推拉杆，所述推拉杆贯穿取样筒的表面并延伸至取样筒的内部，所述推拉杆位于取样筒内部的一端固装有活塞，实现了对气体取样器进行密封的功能，改进了气体取样器的样式，可以防止气体取样器内部的气体与外界空气连通。In a Chinese patent with publication number CN219121822U, a highly sealed gas sampler is mentioned, comprising a sampling barrel and a fixed block, wherein the fixed block is connected to one end of the sampling barrel, a suction nozzle is arranged on the side of the fixed block away from the sampling barrel, a push-pull rod is slidably connected to the outer surface of the sampling barrel, the push-pull rod passes through the surface of the sampling barrel and extends to the interior of the sampling barrel, a piston is fixedly mounted on one end of the push-pull rod located inside the sampling barrel, thereby realizing the function of sealing the gas sampler, improving the style of the gas sampler, and preventing the gas inside the gas sampler from being connected to the outside air.
然而为保证一氧化碳的浓度需要通过化学吸收法或者是分离法实现提纯效果，由于一氧化碳在提纯时需要进行吸附和过滤处理，且检定管需要和储存管进行分离，在长时间使用下，检定管和储存管之间的密封效果会下降，造成检定管内进入其他的气体，从而影响到一氧化碳的检测。However, in order to ensure the concentration of carbon monoxide, it is necessary to achieve purification through chemical absorption or separation methods. Since carbon monoxide needs to be adsorbed and filtered during purification, and the test tube needs to be separated from the storage tube, the sealing effect between the test tube and the storage tube will decrease after long-term use, causing other gases to enter the test tube, thereby affecting the detection of carbon monoxide.
为此，本领域技术人员提出了一种抗干扰一氧化碳检定管来解决背景技术提出的问题。Therefore, those skilled in the art have proposed an anti-interference carbon monoxide test tube to solve the problems raised by the background technology.

When the protection rod 7 is closed, the protection rod 7 protects the test tube 4 to avoid damage to the test tube 4, and the protection rod 7 is used to rotate in the opposite direction to open one end of the test tube 4, and the test tube 4 is fixed to the side wall of the connecting tube 304 by threaded connection between the test tube 4 and the connecting tube 304, and the protection rod 7 is rotated at the same time to make one end of the protection rod 7 clamped on the side wall of the connecting tube 304, so that the test tube 4 is fixed to the side wall of the connecting tube 304, and the connecting tube 304 is pushed. 04, so that one end of the connecting pipe 304 is embedded in the interior of the tube body 1, and the threaded sleeve 301 contacts the outer side of the upper tube body 1, and the connecting pipe 304 is rotated in the opposite direction to make the connecting pipe 304 clamped in the interior of the tube body 1, and the connecting pipe 304 and the interior of the tube body 1 form a sealed state, and the rotating plate 203 is pushed to embed into the interior of the impeller 204, and the impeller 204 is driven to rotate by the rotation of the rotating plate 203. At the same time, the impeller 204 will drive the torsion spring 205 to rotate synchronously when rotating. It is worth noting that the torsion spring 205 needs to be tightened first, and the tube body 1 and the sleeve 201 are connected by threaded connection. By pushing the connecting pipe 304, the connecting pipe 304 is The end is embedded into the interior of the tube body 1, and the threaded sleeve 301 contacts the side wall of the tube body 1, and the sleeve 201 is pushed to the position where carbon monoxide needs to be detected. By pulling the rotating plate 203, the torsion spring 205 can rotate in the opposite direction. The reverse rotation of the torsion spring 205 drives the impeller 204 to rotate in the opposite direction. The suction force generated by the reverse rotation of the impeller 204 allows the carbon monoxide mixed gas to enter the interior of the tube body 1. Through the cooperation of the adsorption cotton 206 and the filter cotton 207 in the tube body 1, the carbon monoxide gas is filtered and processed to reduce the components of other gases in the carbon monoxide. By pushing the connecting tube 304, the side wall of the connecting tube 304 contacts the magnetic block 306 in the tube body 1. The connecting tube 304 is fixed by two magnetic blocks 306, and the connecting tube 304 is in an embedded state, thereby improving the sealing effect between the connecting tube 304 and the tube body 1. At the same time, when the connecting tube 304 moves, the push rod 307 pushes the baffle 303 to move, so that the carbon monoxide filtered in the tube body 1 enters the interior of the test tube 4, and the concentration of carbon monoxide is detected through the test tube 4 to prevent other gases from entering the test tube 4 and causing inaccurate carbon monoxide detection. When the detection is completed, the connecting tube 304 is pulled to make the spring 302 in the tube body 1 push the baffle 303 to move, so that the interior of the tube body 1 is in a sealed state, thereby ensuring the next detection of carbon monoxide.
实施例二：本实施例与上一个实施例基本相同，区别在于，所述叶轮204的外部转动连接在扭簧205一端，所述转板203侧壁嵌入在叶轮204的一端，所述套筒201螺纹连接在管体1的侧壁，所述过滤棉207位于吸附棉206的外侧。Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the external rotation of the impeller 204 is connected to one end of the torsion spring 205, the side wall of the rotating plate 203 is embedded in one end of the impeller 204, the sleeve 201 is threadedly connected to the side wall of the tube body 1, and the filter cotton 207 is located on the outside of the adsorption cotton 206.
由上可知，通过对叶轮204的转动，使叶轮204形成反吸力，使管体1内的气体全部排出，减少管体1内其他气体的存在，同时在反向吸力作用下，使吸附棉206和过滤棉207内杂质进行分离处理，减少吸附棉206和过滤棉207内部堆积灰尘的情况。As can be seen from the above, by rotating the impeller 204, the impeller 204 forms a reverse suction force, so that all the gas in the tube body 1 is discharged, reducing the presence of other gases in the tube body 1. At the same time, under the action of the reverse suction force, the impurities in the adsorption cotton 206 and the filter cotton 207 are separated and processed, reducing the accumulation of dust inside the adsorption cotton 206 and the filter cotton 207.
