Abstract

The invention provides a fire alarm device and relates to the field of alarm devices. The fire alarm device comprises a shell. A controller is fixedly mounted on one side of the shell. Slide grooves are symmetrically arranged in two sides of the inner wall of the shell. Limit blocks are mounted at the tops and bottoms of the slide grooves. A slide rod matched with each slide groove is mounted on each slide groove. A support plate is fixedly mounted between the slide rods. Support rods are symmetrically mounted at the bottom of the support plate. A sound production plate is fixedly mounted at the bottoms of the support rods. Fixing blocks are symmetrically mounted at the top of the support plate. The fire alarm device has the advantages that by a pressure sensor, a support spring and the slide grooves, impact of an impacting ball when the impacting ball impacts the sound production plate is reduced effectively, the pressure sensor receives the impact pressure, a motor reverses when the pressure is excessively large, impact of the impacting ball on the sound production plate is reduced, the structural integrity of the sound production plate is protected effectively, and the service life of the alarm device is prolonged effectively.

Description

technical field [0001] The invention relates to the technical field of alarm devices, in particular to a fire alarm device. Background technique [0002] Fire refers to burning that is out of control in time or space. Among various disasters, fire is one of the main disasters that most frequently and commonly threatens public safety and social development. Human beings can use and control fire. It is an important symbol of progress, so the history of human use of fire and the history of fighting against fire go hand in hand. While using fire, people constantly summarize the law of fire occurrence and reduce fire and its damage to humans as much as possible. When encountering fire, people need to escape safely and as soon as possible. [0003] When a fire breaks out, it is impossible for people in the building to know the fire at the first time, so it is necessary to install sensors in various places of the building. When a fire breaks out, the sensor sends information to th...
