Abstract

The invention belongs to the field of gas detection and especially relates to a convenient gas detector. The convenient gas detector comprises a housing and an ionization chamber, an ultraviolet driver, a signal detection circuit, a single-chip microcomputer, a liquid crystal display module, a USB interface communication module and an audible and visual alarm which are arranged inside the housing. The ionization chamber is positioned at the lower part of the housing. The ultraviolet driver is disposed on the ionization chamber. The signal detection circuit is mounted near the ultraviolet driver. A micro-pump driving module is arranged at the right side of the signal detection circuit. A DC high-voltage module is arranged at the right side of the micro-pump driving module. The single-chip microcomputer is disposed above the ultraviolet driver. The liquid crystal display module is mounted near the single-chip microcomputer. The USB interface communication module is arranged near the liquid crystal display module. The audible and visual alarm is disposed near the USB interface communication module. The convenient gas detector provided by the invention has a simple and reasonable structure, is small in volume, is convenient to carry, meets real-time and continuous detection requirements of working sites and has a wide application range.

Description

technical field [0001] The invention belongs to the field of gas detection, in particular to a convenient gas detector. Background technique [0002] The development of modern organic chemical industry, petroleum refining and other industries has provided human beings with more and more new materials and new products, but at the same time it has also brought more and more organic substances. In addition to the common inorganic gases in industrial safety, such as carbon monoxide, hydrogen sulfide, nitrogen oxides, etc., organic substances that are more toxic and harmful have also begun to attract widespread attention. If you work in an environment containing these gases for a long time, they can damage the hematopoietic function of the human body, and in severe cases, it will induce lung cancer, leukemia and other diseases, which will seriously endanger people's health. Therefore, on-site low-concentration and continuous detection of harmful gases should become a necessary m...
