Its main function is to sound an alarm when the concentration of combustible gas exceeds the preset safety threshold, thereby preventing dangerous situations such as fire and explosion. For example, smoke alarms require regular fault detection during daily use to ensure that the alarm can work accurately and stably at critical moments.

[0003] The document with the publication number CN219778330U specifically discloses a fire detection device, including a smoke rod body and a smoke generator installed on the smoke rod body. This patent uses a positioning device to assist the detection personnel to make the nozzle correspond to the air inlet of the smoke alarm, so that the detection personnel can quickly match the nozzle with the air inlet of the smoke alarm, reducing the burden of the detection personnel and facilitating the detection of the smoke alarm. However, after the smoke alarm is detected by spraying smoke from the nozzle, the smoke cannot be effectively recovered, causing the sprayed smoke to spread into the indoor air. The smoke contains a variety of harmful substances, such as particulate matter, harmful gases, etc. After these substances spread indoors, they will seriously pollute the indoor air, causing the air quality to decline and posing a threat to human health.
