Description
Technical field
This utility model relates to alarm technical field, particularly relates to a kind of gas concentration lwevel alarm.
Background technology
Being a kind of colorless and odorless, gas the most combustion-supporting, non-flammable under carbon dioxide room temperature, density is bigger than air, is slightly soluble in water, reacts with water and generates carbonic acid it is considered to be aggravate the main source of greenhouse effect.Carbon dioxide is one of arch-criminal of global warming, global warming in outdoor, in indoor to one of main cause that Health Impact and traffic safety misgivings can not be ignored especially.In the middle of life, carbon dioxide is that the mankind are manufacturing all the time but through commonly overlooked gas, the change of 21 new century popular life kenels, especially modern to fear that noise adds open-air quality the best, people are to seek isolation noise and enjoy living space or comfortable facility that office space air conditioning system is brought, for a long time by airtight for indoor window so that indoor carbon dioxide levels is far above outdoor meansigma methods, medical science is more had to sleep continuous eight hours in being reported in cold air room, grow owing to air has the convection current of suitable foot to help dust mite, there will be nasal obstruction in the morning, skin is red the symptom such as itches.The concentration of carbon dioxide reaches more than 1%, and people will be made to have a dizzy spell.Reach 4 ~ 5%, people will nausea and vomiting, hypopnea.More than 10%, people will be dead.
Utility model content
The purpose of this utility model is to solve shortcoming present in prior art, and a kind of gas concentration lwevel alarm proposed.
To achieve these goals, this utility model adopts the technical scheme that
A kind of gas concentration lwevel alarm, including base, housing and the controller being arranged in housing, described enclosure interior is provided with test chamber, the upper end of described test chamber connects air inlet pipe, described air inlet pipe is provided with air exhauster, the lower end of described test chamber connects escape pipe, it is provided with mounting seat in described test chamber, described mounting seat is arranged on the center of test chamber by bracing frame, described mounting seat is provided with gas concentration lwevel sensor, setting alarm device on the outer wall of described housing, described controller electrically connects with gas concentration lwevel sensor, alarm device respectively.
