[0046] The device in this embodiment can switch between sterilization and degradation functions, as detailed below:
[0047] like Figure 2 As shown, when using the device of this embodiment for sterilization, clean air B enters the air input mechanism 1 from the air inlet, and then enters the vaporized hydrogen peroxide loading mechanism 2 through the three-way valve 4 to obtain air A carrying vaporized hydrogen peroxide, which is then discharged from the air outlet and can be introduced into a closed space for sterilization.
[0048] like Figure 3 As shown, when using the device of this embodiment for degradation, air A carrying vaporized hydrogen peroxide enters the air input mechanism 1 through the air inlet, and then enters the dehumidification and pyrolysis mechanism 3 through the three-way valve 4.

[0049] When it is necessary to clean the internal piping of the device, air can be introduced through the air inlet and then discharged through the exhaust pipe 6.

[0055] When using the device of this embodiment for degradation, air A carrying vaporized hydrogen peroxide enters the air input mechanism 1 from the air inlet under the action of the fan 11. After being heated by the heater 12, it enters the dehumidification pyrolysis mechanism 3 through the three-way valve 4. In the dehumidification pyrolysis mechanism 3, the hydrogen peroxide in the air is degraded by the dehumidification pyrolysis catalyst 31 to obtain clean air B, which is discharged from the air output port through the three-way discharge valve 5.
