Description

Technical Field

[0001] The present invention relates to the technical field of gas detection, and in particular to a portable gas detection device. Background Art

[0002] In the process of production, experiment, etc., some toxic, harmful, polluting, and corrosive gases are often used or generated to achieve a certain purpose. Usually, the residual or reaction-generated gases are treated to avoid harm. However, in the actual operation process, gas leakage may occur due to aging, wear, looseness, etc. of the reaction equipment or processing equipment. If the gas leakage problem cannot be timely known, it will cause safety hazards. For example, when working in coal mines, dangerous and harmful gases such as carbon monoxide and formaldehyde in the mine need to be monitored in real time, and attention should also be paid to detecting the air quality in narrow spaces. Although the current gas detection can detect different harmful gases, it cannot better achieve accurate gas detection in the face of harsh working environments. It has at least the following problems: 1) The current portable gas detection instrument cannot achieve harsh or space-intensive working environments; 2) The current gas detection instrument cannot be carried by the operator and is not convenient for working in a mobile working environment; 3) The detection accuracy of the working components of the current detection instrument is not high enough.

[0003] For example, in a Chinese invention patent document with the patent name of "A Gas Detection Device" and the authorization number of CN108303216B", the gas detection device includes a gas collection chamber, a detection component, a pipeline, and a plasma generator; the gas collection chamber is used to collect gas samples; the first end of the pipeline is connected to the gas collection chamber, and the second end is connected to the gas inlet of the plasma generator; the nozzle of the plasma generator faces the detection component; the detection component can chemically react with the plasma generated by the gas to be detected, so that the detection surface of the detection component is etched to detect whether the gas to be detected is contained in the gas sample, but the actual use steps are more cumbersome, and the detection accuracy cannot achieve a high accuracy.

[0004] For another example, in the Chinese invention patent document with the patent name of "A gas detection device and detection method" and the authorization number of CN 111766330B, the detection device includes a mixer, a gas conveying device to be tested, a catalytic gas conveying device and a catalytic combustion sensor. The mixer is provided with a guide area and a mixing area, and a premix area, a first gas guide area and a second gas guide area are formed in the mixing area. The gas conveying device to be tested is connected to the first gas guide area, and the catalytic gas conveying device is connected to the second gas guide area and can convey the catalytic gas to the premix area. The gas to be tested and the catalytic gas are mixed in the premix area to form a mixed gas, and the mixed gas is guided to the catalytic combustion sensor through the guide area; the detection method includes S1: conveying the gas to be tested and the catalytic gas to the mixer for mixing to obtain a gas sample to be tested; S2: detecting the gas sample to be tested by the catalytic combustion sensor to obtain the concentration value of the combustible gas. Although the detection effect of this gas detection device has met certain requirements, its device structure design is not convenient enough and it is difficult to use different gas detection environments.

[0005] Therefore, the gas detection devices in the prior art still have technical problems such as limited detection capability and poor applicability. Summary of the invention
