a smoke alarm

Abstract

An embodiment of the present invention provides a smoke alarm, including: a rear shell assembly, a middle shell assembly, a front cover assembly, a smoke sensor assembly and a monitoring assembly; the rear shell assembly includes: a rear shell; the middle shell assembly includes: a middle shell cover and middle shell; the front cover assembly includes: a front cover; the monitoring assembly includes: a camera; the smoke sensor assembly is installed between the rear shell and the middle shell; the space between the middle shell and the middle shell forms a smoke sensing area; A smoke-sensing through hole is provided, so that the smoke-sensing area is communicated with the first cavity formed by the rear shell and the middle shell cover; the monitoring component is installed in the second cavity formed between the middle shell and the front cover; the front cover is provided with There are camera installation through holes, so that the camera of the monitoring component can shoot through the lens installation through holes. Since the smoke alarm has a monitoring component and a smoke sensor component, after the monitoring component and the smoke sensor component are electrically connected and turned on, the smoke alarm can timely know the specific fire situation while alarming the smoke.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a smoke alarm. Background technique [0002] With the rapid development of the economy, many high-rise residential buildings and densely populated office buildings have appeared. In order to ensure the safety of personnel in high-rise residential buildings and office buildings, a fire protection system is essential. In the fire protection system, a smoke alarm is usually included, and the location of the fire can be quickly determined through the smoke alarm, which can quickly extinguish the fire and prevent the fire from expanding. [0003] Under normal circumstances, when a fire occurs, smoke will enter the inside of the smoke alarm and be sensed by the smoke sensor installed inside the smoke alarm. When the concentration of smoke reaches the alarm concentration of the smoke sensor, the smoke alarm will generate an alarm. signal to alarm. [0004] However, since the s...
