And a particle mounting member 320 for mounting slow-release sterilization particles is arranged in the second mounting cavity 310, and an air outlet 311 is formed at one end of the second mounting cavity 310 in the length direction, that is, the air outlet 311 and the first opening 211 are located on the same side of the second mounting cavity 310 (the first mounting cavity 210) in the length direction. It is understood that the air outlet 311 is used for discharging the slow release sterilizing particles. It should be noted that, the slow-release sterilization particles contain sterilization substances, the sterilization substances can be slowly released by the slow-release sterilization particles, and the sterilization substances are in a gaseous state at normal temperature, that is, the sterilization substances are in a gaseous state after being released by the slow-release sterilization particles and discharged from the air outlet 311, and after being discharged, the sterilization substances can be combined with the water mist discharged from the atomizer 500 to form sterilization water mist, so that the sterilization effect of a short-time large area can be realized.

Specifically, as mentioned above, the inner surface of the second housing 230, the first housing 220 and the mounting plate 100 together define the first opening 211 facing a predetermined direction perpendicular to the mounting plate 100. That is, inside the first mounting cavity, the hydroxyl molecules generated by the ionizer 400 and the mist generated by the atomizer 500 are discharged from the first opening 211, and since the first opening 211 is oriented perpendicular to the mounting plate 100 and is oriented toward the side of the air outlet 311 (i.e., the predetermined direction), both the hydroxyl molecules and the mist are guided by the first opening 211 to be discharged toward the predetermined direction, and at this time, the hydroxyl molecules and the mist can further contact and mix with the slow-release sterilizing particles discharged from the air outlet 311, so as to improve the sterilizing effect.
