Combined type smoke and temperature sensing fire detector

Abstract

The invention relates to a combined type smoke and temperature sensing fire detector, and relates to the field of fire detection technology. The combined type smoke and temperature sensing fire detector comprises a universal base and a universal middle buckle arranged in the universal base, the peripheral side of the universal base is covered with an outer cover, the outer cover is buckled with the universal base, the peripheral side of the outer cover is provided with a plurality of openings, a laser lamp is arranged on the side surface, away from the base, of the universal middle buckle, a laser emitted by the laser lamp is emitted out of the opening, and a built-in power system used for supplying power to the laser lamp is arranged in the universal base. The laser lamp works, the laser is emitted from the opening of the outer cover till that the laser is irradiated to the position of an emergency exit, and the effects that correct guidance is made for the trapped person to escape, the time for the trapped person to search for the emergency exit in dense smoke is shortened, and the escape probability is improved are achieved.

Description

technical field [0001] The present application relates to the field of fire detection technology, and in particular to a composite smoke and temperature-sensing fire detector. Background technique [0002] Photoelectric smoke detectors are developed using the characteristic that smoke generated during a fire can change the propagation of light. It is divided into two types: shading type and scattering type. During use, regular cleaning is required to remove accumulated dust. Especially the light source and the surface of the lens should not have dust and dirt, otherwise it will lead to a significant drop in sensitivity or even failure. [0003] In view of the above-mentioned related technologies, when a fire occurs, the power supply in the building is cut off, and the indoor smoke is everywhere, which affects the position of the trapped people to find the emergency exit. The inventor believes that only through the emergency exit signboard, there is inconvenience Personnel...
