Furthermore, the first channel 25 connects to the second channel 33 through the first through hole 26, and the first channel 25 and the second channel 33 constitute an air inlet channel 18 extending along the first direction. The air inlet channel 18 can extend from the working chamber 15 to the first inlet 28. The space between the outer extension plate 30 and the intermediate plate 32, and the space between the annular plate 23 and the baffle 29 constitute a second air outlet channel 21, which can extend from the working chamber 15 to the first opening 35. The cover 7 and the diffuser 8 form two second air outlet channels 21. The outlet of the second air outlet channel 21 (i.e., the first opening 35) can be separated by the annular plate 23, so that the first opening 35 is far away from the air inlet channel 18, preventing the released ionized air from being re-inhaled into the sterilization device and avoiding air short-circuiting.
[0049] In some exemplary embodiments, such as Figures 3 to 6 As shown, the top cover 6 is located at and passes through the mounting hole 14. The support rib 31 rests on the storage cabinet 1, and the storage cabinet 1 supports the support rib 31. The sterilization device also includes a filter 9, which is detachably installed in the air inlet duct 18.
