In order to further prevent the air entering the second channel 403 from being atomized by the atomization mechanism and flowing back to the disinfection and purification mechanism to cause burden on the disinfection and purification mechanism, a vent 40331 may be provided on the other end side wall of the second channel 403, the second channel 403 is communicated with the atomization chamber 50 through the vent 40331, another part of purified air enters the atomization chamber 50 through the second channel 403 penetrating through the air guide chamber 40, and flows out from the vent 40331 on the side wall of the second channel 403, and forms water mist after being humidified by the atomization chamber 50 to be sprayed out from the second air outlet 103, even if part of water mist is not sprayed out from the second air outlet 103, the water droplets are adhered to each other in the atomization chamber 50 and form on the side wall of the second channel 403, and the water mist is not easy to enter the second channel 403 to flow back to the disinfection and purification mechanism through the vent 40331. Preferably, the other end of the second channel 403 extends to the top of the atomization chamber 50, and a vent 40331 is provided on the side wall of the second channel 403 near the top of the atomization chamber 50.

In some embodiments, the air guiding cavity 40 may include an upper air guiding cavity 402 and a lower air guiding cavity 401, and the air guiding cavity 40 is formed by connecting the upper air guiding cavity 402 and the lower air guiding cavity 401, so that the production is convenient (the upper air guiding cavity 402 and the lower air guiding cavity 401 may be respectively cast by two molds, and then the upper air guiding cavity 402 and the lower air guiding cavity 401 are assembled and connected to form the air guiding cavity 40). The opening 4011 is provided in the lower air guiding chamber 401. The second channel 403 penetrates the upper air guiding cavity 402 and the lower air guiding cavity 401.

Since the second air duct 302 is communicated with the first air outlet 102 through the first channel 404 of the air guiding cavity 40; the second air duct 302 is communicated with the second air outlet 103 through the second channel 403 penetrating the air guiding cavity 40, so in this embodiment, the first air outlet 102 may be configured to be U-shaped, L-shaped, mouth-shaped, etc. corresponding to the outer periphery of the air guiding cavity 40, in the embodiment, the U-shaped is taken as an example, and the second air outlet 103 is located in the U-shaped opening 4011 of the first air outlet 102.

To accelerate the discharge of the purified air, the width of the first channel 404 along the air flowing direction of the first channel 404 near the first air outlet 102 may be gradually reduced; the width of the second channel 403 near the second air outlet 103 in the air flow direction of the second channel 403 gradually decreases. The width of the first channel 404 and the width of the second channel 403 are gradually reduced, which is favorable for accelerating the discharge of the purified air or accelerating the fog diffusion speed of the fog outlet in the atomization cabin 50 (the fog outlet is arranged on the atomization cabin 50 corresponding to the second air outlet 103), thereby accelerating the disinfection and purification speed. Of course, the reinforcing ribs 40311 may be formed at the first connection portion 4031 during the gradual reduction of the width of the second channel 403, so that the reinforcing ribs 40311 help to increase the structural strength of the second channel 403 and avoid the breakage of the connection portion between the second channel 403 and the air guiding cavity 40.
