Abstract

The invention relates to the structural design of a gas sensing head, and in particular relates to a quartz enhancing photoacoustic spectrophone and an assistant assembling device and an assistant assembling method thereof. The technical problem that the existing quartz enhancing photoacoustic spectrophone is not high in sensitivity and low in assembling efficiency is overcome. The quartz enhancing photoacoustic spectrophone comprises a quartz tuning fork and a pair of miniature sound resonant cavities fitting with the tuning fork, and also comprising a structural support for fixing the quartz tuning fork and the pair of miniature sound resonant cavities, wherein the structural support comprises a cube, the top of the cube is downwards provided with a groove along a central line, the center of the groove is downwards provided with a through hole, and a pair of raised tubular trays with cube structures are formed on two sides of the groove. According to the quartz enhancing photoacoustic spectrophone and the assistant assembling device and method thereof, through designing the assembling technological process and researching the assisting assembling device, assembling efficiency is greatly improved, and the technical problem that the quartz enhancing photoacoustic spectrophone is not high in assembling precision is overcome.

Description

technical field [0001] The invention relates to the structural design of a gas sensor head, in particular to a quartz-enhanced photoacoustic spectrum sound detector and an auxiliary assembly device and method thereof. Background technique [0002] Real-time detection of trace gases in the air has major applications in various fields such as industrial process control, environmental testing, medical analysis, and exhaust emission monitoring. As a traditional spectral detection technology, photoacoustic spectroscopy has been widely used in the above fields because of its zero absorption background, high detection sensitivity, and no wavelength selectivity in detection. In particular, the quartz-enhanced photoacoustic spectroscopy technology developed in recent years uses quartz tuning forks instead of microphones in traditional photoacoustic spectroscopy to detect gases, greatly reducing the size of the device and achieving good results. The core detection part of this device...
