Description
Technical field
The utility model relates to a kind of enviromental monitoring equipment, a kind of environment inside car monitoring alarm of saying so more specifically, formaldehyde and/or the carbon monoxide gas body burden in the monitoring car in real time.
Background technology
Along with increasing sharply and the raising of health of people awareness of safety of automobile pollution, air quality monitoring more and more is subject to people's attention in the car.Usually can contain vehicle production in the car and add the oxycarbide that formaldehyde, benzene series thing, oxides of nitrogen and engine that man-hour, used starting material brought turn round for a long time and produce, wherein with formaldehyde and the carbon monoxide harm maximum to the people.
Carbon monoxide is colorless and odorless gas, is difficult for being discovered by the people, and the human and animal is had height toxicity.Carbon monoxide is combined with haemoglobin after entering blood by breathing, forms carbonyl hemoglobin, thereby makes human body anoxia be subjected to major injury.In volume fraction is the carbon monoxide environment of 1600ppm, stay and will feel headache, dizziness in 20 minutes, will be dead after 1 hour.
Studies show that formaldehyde has become first kind carcinogen, can cause human diseases such as nasopharyngeal carcinoma, CARCINOMA OF THE NASAL CAVITY and nasal sinus cancer.If content of formaldehyde reaches the 0.1-2.0 milligram in the air in airtight environment, 50% normal person can smell foul smell; Reach the 2.0-5.0 milligram, eyes, tracheae will be subjected to intense stimulus, occur sneezing, symptom such as cough; Reach more than 10 milligrams expiratory dyspnea; Reach more than 50 milligrams, can cause critical illness such as pneumonia, even cause death.
Along with increasing the weight of day by day of atmospheric pollution, increasing driver closes vehicle window when selecting to drive and uses air-conditioning; During the broiling summer and cold people in winter also can use air-conditioning for a long time; Also having some to like driving air-conditioning has a rest in car.Under above-mentioned these situations, the running of engine long time, discharge toxic gases such as a large amount of carbon monoxide, these gases are detained in limited space for a long time, add door and window and close, inner air and outer air does not circulate, and the oxygen in the car can be consumed gradually, make the people produce intoxicating phenomenon, there is carbon monoxide poisoning event generation in a large amount of cars every year in China.
Sampling Detection result according to room air monitoring center of Chinese interior decoration association has nearly 7 one-tenth the automobile storage problem that formaldehyde exceeds standard in car, some car even exceed standard more than five or six times.Find that according to an external research test new car harmful gas concentration in the back car that dispatches from the factory is very high, and sustainable volatilization has in a large number and takes place because environment inside car pollutes the traffic hazard that causes more than 6 months every year.
It is the important means that prevents that toxic gas is poisoned that the interior carbon monoxide of car or formaldehyde alarm are installed.Though the carbon monoxide alarm of indoor use is of a great variety, also be not suitable for the carbon monoxide alarm that in car, uses at present.This mainly is based on following some reason: the one, and the gas sensor that adopts in the carbon monoxide alarm at indoor use mostly is cheap semiconductor-type gas sensor, has defectives such as precision is low, discreteness big, temperature is floated seriously, reliable serviceable life is too short; The 2nd, mostly be voltage ratio to pattern with the matching used sample circuit of above-mentioned semiconductor-type gas sensor, have defectives such as precision is low, anti-electromagnetic interference capability difference; The 3rd, the semiconductor-type gas sensor needs work at high temperature, power consumption is very big, electric current generally can reach about 100mA, this just makes common powered battery become unrealistic, and can provide the position of power supply considerably less in the car, in case taken and will bring great inconvenience to the driver by this alarm, after vehicle is flame-out, can't continue to provide power supply simultaneously, also just can't accomplish to monitor in real time environment inside car.In view of the present miscellaneous indoor carbon monoxide alarm of above reason can't be applied in the environment inside car.
Though formaldehyde is as a kind of very general indoor pollutant, its harm is widely known, and at present detection means commonly used is limited in the industry, comprises that mainly formaldehyde detects three kinds of box, off-line type analysis and portable formaldehyde detecting devices.Formaldehyde detects box and belongs to qualitative detection, and the cycle is longer, generally wants 6 to 8 hours just can provide testing result, safety that can't real-time guard people lives and properties; Mostly the off-line type analysis is that the resident entrusts environment measuring department to carry out, and coherent detection mechanism extracts atmospheric sample and takes back in the laboratory and analyze to the scene, can't provide warning message timely equally; Though portable formaldehyde detecting device can be taken to the place that various needs detect by people, response is more fast also arranged, expensive, can't popularize use.Simultaneously, monitor environment inside car in real time as need, need detecting device to work without cessation, therefore also have above-mentioned powerup issue.
Therefore, need a kind of environmental monitoring alarm that is suitable for use in the car of exploitation.
