[0032] Moreover, since the active mist ion generating module 200 is built into the chassis 20, the response speed is fast, and the active mist ions can take effect immediately after being released from the active mist ion generating core 220, with small activity loss, which has a positive effect on improving the efficiency of air disinfection and purification.

[0033] It should be noted that the active mist ion generating mechanism 220 is existing and can collect water vapor in the air and convert water into active nano-scale water mist particles, namely active mist ions, by electrochemical means. The active mist ions can gather dust and cause the dust to settle. Moreover, the active mist ions contain active substances such as oxygen-containing free radicals and hydroxyl free radicals, which can disinfect viruses and bacteria by extracting hydrogen, and decompose formaldehyde, benzene, toluene, odorous substances, etc., thereby achieving disinfection and purification of the air.

[0038] Furthermore, the first mesh plate 311 is bent on one side away from the second mesh plate 312 to form a first bending edge 313, and the second mesh plate 312 is bent on one side away from the first mesh plate 311 to form a second bending edge 314; the first bending edge 313 and the second bending edge 314 make it easy for installers to take the ventilation mesh plate 310 and are not likely to cause harm to the installers.
