[0002] Smoke fire alarm device, usually called smoke alarm or independent smoke fire detection alarm, is a device that does not need to be connected to wires and is powered by batteries. When a fire occurs in the early stage, once smoke is generated, the smoke alarm can sense and sound an alarm, leaving time for escape and alarm. This alarm is widely used in Internet cafes, dance halls, coffee shops, leisure halls, residences and other places for fire safety monitoring.
[0003] The existing fire detection alarm is provided with a smoke flow groove on the outer surface of the shell, so that smoke can enter the interior of the fire detection alarm, thereby sensing the smoke. Usually, there are no related dust-proof components around the smoke flow groove on the outer surface of the fire detection alarm shell, so that the electronic components inside the fire detection alarm are easily affected by dust. When the room is undergoing decoration work, a large amount of dust and other impurities may drift from the smoke flow groove into the interior of the fire detection alarm, which may damage the electronic sensing devices inside the fire detection alarm.
