s3-6, after the time T, acquiring a differential pressure delta P5 by the differential pressure sensor b5 of the toilet in the pollution area and the pollution area, and judging whether the differential pressure delta P5 of the differential pressure sensor b5 of the toilet in the pollution area and the pollution area is in a set range:

If the pressure difference delta P5 of the toilet pressure difference sensor b5 between the pollution area and the pollution area is smaller than the set range, the set range is-15 Pa to-10 Pa, and the duration time is longer than or equal to the time T1, the gear of the exhaust module E is reduced; returning to the step S3-6;

If the pressure difference delta P5 of the toilet pressure difference sensor b5 between the pollution area and the pollution area is larger than a set range, the set range is-15 Pa to-10 Pa, and the duration time is larger than or equal to the time T1, the gear of the exhaust module E is increased;

If the differential pressure delta P5 of the differential pressure sensor b5 between the pollution area and the toilet in the pollution area is in the set range, the set range is-15 Pa to-10 Pa, and the previous operation gear of the air exhaust module E is maintained.
