[0002] Smoke alarm is actually another name for smoke sensor or smoke alarm. Smoke alarm achieves fire prevention by monitoring the concentration of smoke. The existing smoke alarm has a simple structure and single function. It does not have the function of automatic fire extinguishing when smoke is detected. Therefore, we propose a smoke alarm for indoor fire safety engineering.

[0003] The current smoke alarms rely on the air in the room to automatically flow into the alarm after smoke is generated, and then the alarm can detect whether there is smoke. The existing alarms cannot circulate the external air independently, so that the fire can only be discovered after a period of time. At the same time, it is inconvenient for people to install the alarm. To solve the above problems, we have launched the following device. Utility Model Content
