Description

Independent fire detection alarm

Technical Field

The application relates to the field of fire alarm, in particular to a stand-alone fire detection alarm.

Background

With the increase of fire and electricity consumption in modern buildings, the occurrence frequency of fire in the buildings is higher and higher. Once a building fire happens, adverse factors such as untimely fire suppression, lack of fire extinguishing equipment, scare and misbehavior of bystanders, slow escape and the like easily occur, and finally, serious life and property loss is caused. One of the important means for detecting fire when the smoke alarm is used for detecting that a large amount of smoke causes fire, the smoke alarm has the function of generating alarm so as to timely warn people in a building, shorten the time for discovering and controlling the fire, enable the people to extinguish the fire or escape in time and further reduce property loss,

chinese patent publication No. CN208477688U discloses a stand-alone fire detection alarm. The fire detection alarm comprises an upper cover, wherein a battery bin is arranged on the inner side of the upper cover, and a battery installation indicating unit is arranged on the right side of the battery bin and used for making a fire detection alarm without a battery obviously incapable of being installed on a fixed base.

In view of the above-mentioned related arts, the inventors believe that there are disadvantages that when a fire just occurs, the amount of smoke generated by a burning object may be small, and the diffusion speed of smoke may be slow depending on the burning position when the object burns, resulting in a great delay in fire alarm by a fire alarm, and indoor personnel may easily lose the optimal fire fighting and escape time.
