Description

Fire-fighting smoke alarm device Technical Field The utility model relates to the technical field of smoke alarm, in particular to a fire-fighting smoke alarm device. Background In the field of modern fire safety, smoke alarm devices are important equipment for guaranteeing life and property safety. At present, part of smoke alarm devices on the market are provided with one magnet at the top of the alarm through 3M glue, then the other magnet is stuck on the roof through 3M glue, and the installation of the smoke alarm device is realized by utilizing the magnetic force between the two magnets. However, this mounting has a number of drawbacks. First, the tackiness of 3M glue can be significantly affected by environmental factors. Under the high temperature environment, the viscosity of 3M glue can be reduced, and the adhesion between the magnet and the alarm and between the magnet and the roof is unstable, so that the smoke alarm device is easy to fall off. For example, in hot summer rooms, especially in direct sunlight areas, temperatures may reach 35 ℃ and higher, at which time the tackiness of the 3M glue may be significantly reduced. In a humid environment, water vapor can infiltrate into the contact surface of the 3M glue and the object to damage the viscous structure of the 3M glue, and the magnet can be dropped off. Like the plum rain season in the south, the air humidity is in a higher level for a long time, and the smoke alarm device adopting the installation mode often falls. Second, the firmness of the 3M paste decreases over time. After long-term use, the 3M adhesive can be aged gradually, and the original viscosity is lost. Smoke alarms are often required to maintain a stable installed condition for a long period of time as a device that operates for a long period of time. However, after the 3M glue is aged, even under normal environmental conditions, the stable installation of the smoke alarm device is difficult to ensure, and the smoke alarm device can be accidentally dropped, so that the timely monitoring and alarm functions of smoke are affected. In addition, the installation mode of double-magnet magnetic attraction is adopted, when the smoke alarm device is impacted or vibrated by external force, the smoke alarm device is easy to displace and even fall off due to limited attraction force between the magnets. For example, in the scenes of house decoration, furniture handling, etc., certain vibrations and collisions are inevitably generated, which is likely to cause a change or drop in the position of the smoke alarm device mounted by means of magnetic attraction, so that the smoke alarm device cannot effectively perform a monitoring function. Therefore, the fire smoke prevention alarm device needs to be designed and improved, and the phenomenon that the alarm falls off and is damaged due to unstable installation is effectively prevented, so that the resource is wasted and the environment friendliness is low is caused.
