When the deodorizing module 20 is desorbed, the room air passing through the deodorizing module 20 is mixed with the desorbed odor molecules to become turbid air. The purified air should be discharged into the room to improve the comfort of the indoor air, and if the turbid air is also discharged into the room, the indoor air may be polluted, which is contrary to the original purpose of eliminating the peculiar smell of the indoor air by the deodorizing module 20.

Referring to fig. 1 and 2, in view of this, in some embodiments, a purge air duct 101 is formed in a housing 10, the purge air duct 101 has an air inlet 1011 and an air outlet 1012 communicating with indoor air, an air door 102 is provided at the air outlet 1012, an air outlet 1013 is provided on the purge air duct 101, the air outlet 1013 communicates with outdoor air, and an air outlet valve 103 is provided at the air outlet 1013.
