Description

Fire detector

Technical field

The utility model relates to a kind of family fire alarming device, particularly relates to a kind of fire detector.

Background technology

Fire detector is in fire automatic alarm system, detects scene, finds the equipment of fire.Fire detector is system " sense organ ", and its effect monitors the generation whether having fire in environment.Once there be the condition of a fire, just by the feature physical quantity of fire, as temperature, smog, gas and radiation light intensity etc. convert electric signal to, and action sends alerting signal to fire alarm control unit immediately.

Comprise several types: smoke fire detector, smoke fire detector a kind ofly responds the solid or the fire detector of liquid particle that burning or pyrolysis produce, and is the maximum a kind of fire detector of use amount.Because the gasoloid that it can produce at the detecting material burning initial stage or smoke particle concentration, therefore, some countries claim smoke fire detector to be " early detection " detector.Common smoke fire detector has ion-type, photoelectric type etc. several.Ion smoke detector is mainly to form by inside and outside two ionization chambers.Outer ionization chamber (i.e. sensing chamber) is porose to communicate with the external world, and smog can enter in sensor from this hole; Internal ionization room (i.e. compensated chamber) is sealing, and smog can not enter.When fire occurs, smoke particle is altered into outer ionization chamber, disturbs the normal operation of charged particle, makes electric current, voltage changes to some extent, destroy the balance between inside and outside ionization chamber, and detector will produce induction and send alerting signal.There are a light-emitting component and a light activated element in optical detector of fire smoke inside, usually the light sent by light-emitting component, scioptics are mapped on light activated element, circuit remains normal, therefrom intercept if any smog, the light arrived on light activated element will significantly weaken, so light activated element just converts the change of light intensity to the change of electric current, sends alerting signal by amplifying circuit; Air suction type; aspirating smoke detector is changed heritage smoke detector and is waited for that smog flies away the passive mode of carrying out detecting of detector; but adopt new theory; namely initiatively Sample acquisition is carried out to air; when the air sample in protected location is sucked sampling conduit by the asepwirator pump of aspirating smoke detector inside; deliver to detector analysis, if find smoke particle, namely send warning.Existing a lot of fire detector also exists the problem of power consumption height and poor accuracy, plays inhibition to the popularization of fire detector.
