[0058] The wind uniformity plate 402 is horizontally distributed and located at the lower end of the guide plate 401 for uniformizing the dispersed wind. The wind uniformity plate 402 is a PVC mesh plate that can perform wind uniformity processing, improve the filtering effect of the second high-efficiency filter 300, and avoid uneven filtering.

[0063] In another embodiment, Figure 4 As shown, the air guide plate 103 is spirally arranged from the side wall of the inner cavity 102 to the bottom wall of the inner cavity 102, and is slightly raised at one end of the air guide plate 103 located on the bottom wall of the inner cavity 102, so as to form a vortex pointing in the direction of the air outlet component 200, so as to facilitate the gathering of the peripheral wind to the lower middle end, and then gather to the position of the air outlet component 200 through the upward gathering for air discharge.

[0064] like Figure 1-Figure 5 As shown, the air outlet assembly 200 includes a bell mouth 201 and an air outlet 202, which is connected to one side of the exhaust cavity 100 where air is collected and is used to discharge air from the side.

[0067] To sum up, the utility model has a compact and reasonable structure and is easy to operate. The quality of fresh air is improved by filtering the air twice, and the wind speed is increased by using a double-stacked fan. The fresh air is then evenly treated by the wind uniformity component 400 to make the air output more uniform. Finally, the evenly-evened fresh air is laterally gathered and discharged through the exhaust chamber 100, thereby improving the air output effect, and has strong practicality.
