Abstract

The invention discloses an active heat dissipation type smoke alarm, and the alarm comprises an installation box installed together with a substrate and an indicator light arranged on the outer side of the installation box; an installation groove is formed in the middle of the inner top wall of the installation box, a rotating shaft is vertically and rotationally installed in the installation groove, and a coil spring is elastically connected between the rotating shaft and the installation groove. By arranging the electromagnetic ring and the permanent magnet plate, the permanent magnet platereciprocates up and down in the mounting box by utilizing the alternating effect of the permanent magnet plate between magnetic repulsion and attraction, so gas below the mounting box can be activelycarried to the monitoring mechanism, and the early warning reaction speed of the equipment is increased; meanwhile, in the reciprocating motion process of the permanent magnet plate, the exchange speed of the interior of the mounting box and external gas is increased, heat emitted by electrical apparatus elements in the mounting box can be rapidly discharged, the situation that the temperature inthe mounting box is too high is avoided, and the service life of the equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to an active heat dissipation smoke alarm. Background technique [0002] With the development of science and technology, fire warning equipment has also made significant progress. The smoke alarm is a kind of advanced fire warning equipment. Compared with the traditional gas sensitive resistor alarm, its operation is more stable and reliable, so it has been widely used. In factories, office buildings, hospitals and other important places. [0003] The monitoring mechanism of the smoke alarm is based on the intensity of infrared beams scattered by smoke particles as a reference. Therefore, only when more smoke enters the box of the smoke alarm during a fire can the smoke alarm detect the fire signal in time. Some smoke alarms are generally installed on the roof. Only when a lot of smoke gathers on the roof, the smoke alarm can issue an alarm, and the response speed i...
