step S100, in the daily use process, most light dust in the environment is isolated outside the dust cover 5, smoke dust in the environment and a small part of light dust pass through the broken-line-shaped smoke dust passage and are separated at the filter cylinder 3, and the light dust falls into the dust collection bin 201 downwards;
step 200, referring to fig. 4 and fig. 7, the smoke is guided into the smoke detection space and detected by the smoke detection sensor 7, and the temperature detection sensor 12 directly detects the smoke in the environment;

case one: if the temperature sensing detection sensor 12 is not triggered yet, the temperature sensing detection sensor 12 is proved to be damaged, and the smoke sensing detection sensor 7 is triggered at the moment, so that a fire disaster is likely to occur, a fire alarm needs to be triggered, and workers are informed that the temperature sensing detection sensor 12 is damaged;
and a second case: if the temperature sensing detection sensor 12 is triggered, it is proved that the smoke sensing detection sensor 7 generates false alarm or high temperature is not detected due to diversity of ignition materials, at the moment, based on the principle that nine air holes are prevented rather than ten, fire alarm is triggered, and the remote control end smoke sensing detection sensor 7 is timely prompted to generate false alarm faults through the communication module.
Step S600, if the smoke detection sensor 7 is not triggered, the temperature detection sensor 12 is triggered; it is necessary to determine whether the temperature-sensing detection sensor 12 has false alarm or the smoke-sensing detection sensor 7 has been damaged;

case one: if the smoke detection sensor 7 is not triggered yet, the smoke detection sensor 7 is proved to be damaged, the fire disaster is detected with high probability, a fire alarm is triggered, and the staff is informed that the smoke detection sensor 7 is damaged;
and a second case: if the smoke detection sensor 7 is triggered, it proves that the temperature detection sensor 12 may report by mistake, and the smoke is not detected due to the diversity of the ignition materials, at this time, based on the principle that the fire is prevented by ten times rather than nine times rather than everywhere, a fire alarm is triggered, and the remote control end temperature detection sensor 12 is timely prompted by a communication module to report by mistake.
