Description

Technical Field

[0001] This utility model belongs to the technical field of smoke alarms, specifically relating to a voice-indicating smoke alarm. Background Technology

[0002] Smoke detectors, as an important fire safety device, are widely used in various buildings such as homes, commercial spaces, and industrial plants, playing a crucial role in fire prevention and early warning. Traditional smoke detectors primarily use simple audible and visual alarms to indicate the occurrence of a fire. These detectors emit identical sounds and lights, and neither conveys evacuation information. While people escaping a fire may receive the alarm signal, they cannot obtain evacuation instructions through these audible and visual alarms. For example, in large commercial buildings or industrial sites, where evacuation routes and precautions vary from area to area, existing smoke detectors cannot provide specific and detailed evacuation guidance.
