Smoke alarm devices for fire fighting

Abstract

The invention relates to the technical field of firefighting, and discloses a smoke alarm device for firefighting, which includes a housing and a wall. The inside of the housing is fixedly connected with a photosensitive component, the inside of the housing is fixedly connected with lamp beads, and the inside of the housing is fixedly connected with The filter membrane is fixedly connected with an electromagnet inside the shell, and is connected with a touch plate inside the shell. The outside of the touch plate is fixedly connected with a fixed assembly, and the outside of the fixed assembly is connected with a clamp rod. Under the interaction between all the structures of the device, the device can exhaust the indoor environment when it is used under normal conditions, which not only ensures the smooth flow of air in the indoor environment, but also makes the smoke emission point far away. The smoke can be gathered to the outside of the device, and the smoke alarm function can be played in time, so that the smoke alarm function of the device is more sensitive.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a smoke alarm device for fire protection. Background technique [0002] Nowadays, as people pay more and more attention to fire safety, the smoke alarm equipment used to detect smoke has become a necessary safety guarantee equipment for people at home. Not only that, most public places are also equipped with such equipment, but now Some smoke alarm devices generally can only sense the situation of high smoke concentration, and cannot discharge the smoke. Although this has an early warning effect, it cannot effectively remove the smoke in the air, and the smoke with too high concentration will block people. In this way, a stampede may occur when escaping, and if the smoke is emitted far from the smoke alarm device, this will affect the normal warning function of the smoke alarm device, and it will not be able to remind people in time. [0003] So in response to these prob...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a smoke alarm device for fire protection, which has the advantages of timely early warning and timely smoke exhaust, and solves the situation that the existing smoke alarm equipment can only sense the relatively high smoke concentration, and The smoke cannot be discharged. Although this has played an early warning role, it cannot effectively remove the smoke in the air. The smoke with too high a concentration will block the sight of people escaping, so that a stampede may occur when fleeing, and If the location where the smoke is emitted is far away from the smoke alarm device, this will affect the normal warning function of the smoke alarm device
