Compound, fresh air is displaced by silicon window；When concentration reaches capacity alarm.So as to reach the purpose of room air safety；And
And provided with screen cover is covered, uv damage can be prevented.
Background technology is because industrial development is too fast, exhaust emissions amount is sharply increased, and the reason such as climate warming, air is serious
Contamination phenomenon is protruded very much, and haze has seriously threatened the healthy and life security of people.Have no need for reticence, in the market really
Real storage is but relatively simple in some air detection equipment and air cleaning facility, and only detection is not purified, or only purifies and do not examine
Survey (such as " flammable gas alarm " circuit, the advanced reader of electrophile, Fujian science tech publishing house, ISBN 7-5335-
2001-7/TN264, P：863-864)." air purifier " is mainly made up of systems such as motor, fan, airstrainers, its
