In this embodiment, the fan 93 is disposed at the second port 92 of the airflow path 9, the opening at the upper end of the ventilation shaft 31 communicates with the first ventilation opening 931 of the fan 93 through the through hole 131 in the top plate 13 of the sterilization chamber 10, and the second ventilation opening 932 of the fan 93 communicates with the second port 92 of the airflow path 9. In order to better communicate the vent shaft 31 with the first vent 931 of the blower 93, in this embodiment, the upper port 312 of the vent shaft 31 is flared and covers the through hole 131 of the top plate 13, and in order to achieve a stable installation of the vent shaft 31, the upper end of the vent shaft 31 is fixed on the top plate 13 of the sterilization chamber 10 through a bearing seat 94.

In addition, a flap 95 is provided across the air flow path 9 in the height direction thereof, and the flap 95 is hinged to the top wall of the air flow path 9. When the airflow passes through, the swinging blade 95 can rotate along with the airflow direction, so that the airflow is guided; when no air flow passes through, the flap 95 can block the air flow channel 9, so that dust, cockroaches and other insects can be prevented from entering the disinfection cavity 10 to pollute the disinfection cavity 10.
