Description
Technical field
The utility model relates to a kind of Portable Detector of Carbon Monoxide.
Background technology
Along with developing rapidly of industry; the place that the mankind contact toxic and harmful gets more and more; cause thus the mankind's harm itself increasing; each intoxication accident; make the to protect mankind inherently safe importance in developing industry of recognizing that people regain consciousness, therefore various harmful gas detecting instruments gradually become industry security produce in requisite safeguard.
Gas detecting instrument instrument application field is extensive, cover industry, agricultural, traffic, science and technology, environmental protection, national defence, the each side such as space flight and aviation and daily life, the common common miniaturization of gas detecting instrument instruments and meters, portable, work alone or be unified into network, be widely used in oil, chemical industry, metallurgical, mining, pharmacy, semiconductor machining, industry spot and the families such as spraying packaging, market, liquefied gas station, gas station, gas stations etc. are civilian, commercialization needs fire-proof and explosion-proof, preventing poisoning, air-polluting place, and Agricultural greenhouse gas detects, biogas is analyzed and biogas security monitoring and environmental protection emergent accident, the attack of terrorism, the aspects such as dangerous material accumulating.
Detect airborne carbon monoxide and have important value. On the one hand, carbon monoxide is scentless, but has height toxicity simultaneously. Therefore for carbon monoxide, present maximum working space concentration is only 30ppm. Now, if at indoor burner or the chimney of existing, at imperfect combustion, while lacking air, in flue gas, carbonomonoxide concentration may be several percent by volume. If smoke pipe blow-by or device chimney exhaust gas be due to disadvantageous pressure dependence, for example, because the chimney adversely extending or operation nearby have smoke exhaust ventilator, and leak into indoorly, can form and cause poisoning carbonomonoxide concentration. This is enough to cause Health cost and even death due to poisoning in worst situation. For example CDC is in " anthracemia: fact sheet provides: have every year 500 people dead due to anthracemia in the U.S.. The in the situation that of vexed combustion, also can form a large amount of carbon monoxide. Except the poisoning danger of personnel, therefore this gas be also used as fire instruction gas and therefore its detection be also used to find ahead of time fire condition.
At present, Portable Detector of Carbon Monoxide device instrument key circuit possesses two aspect functions, require under the state of system boot on the one hand, the input block of man-machine interaction is provided, be on the other hand under system closedown power-down conditions, give with system an of short duration powered on moment is provided, to realize power up function. Because portable apparatus is high for space requirement, when in the situation of instrument finite volume, be difficult to realize the key circuit of many buttons, in order to solve problems, on market, a lot of instruments have adopted the pattern of single-button, can dwindle although it is so machine volume, but because single-button mode is in the situation that expressing multiple meaning, can only use the button length time to distinguish, this has just brought a lot of troubles, complicated operation to operating personnel, difficult memory, easily make mistakes, most key part is easily water inlet also, and instrument especially easily damages.
