Gas detecting device

The invention provides a gas detecting device and relates to the technical field of gas detection, and the problem that whether gas is leaked can not be quickly detected in real time in the prior artcan be solved. The gas detecting device includes a gas collecting chamber, a detecting component, a pipe and a plasma generator. The gas collecting chamber is used for collecting a gas sample. A firstend of the pipe is in communication with the gas collecting chamber, and a second end of the pipe is in communication with a gas inlet of the plasma generator. A nozzle of the plasma generator facesthe detecting component. The detecting component can chemically react with a plasma generated by a gas to be tested such that the detecting surface of the detecting component is etched to detect whether the gas to be tested is contained in a gas sample. 本发明提供种气体检测装置，涉及气体检测技术领域，可解决现有技术中无法快速、实时检测是否有气体泄漏的问题。所述气体检测装置，包括气体收集腔、检测部件、管道、以及等离子体发生器；所述气体收集腔用于收集气体样本；所述管道的第端与所述气体收集腔连通，第二端与所述等离子体发生器的气体进口连通；所述等离子体发生器的喷口朝向所述检测部件；所述检测部件能够与待
