Preferably, the first wind-guiding sheet 160 is inclined at a certain angle relative to the airflow direction, so that the second end of the first wind-guiding sheet is closer to the first fan 40 than the first end, the distance between the first wind-guiding sheet 160 and the first fan 40 is gradually reduced from the first end to the second end, and a guiding effect is provided for the airflow, so that a part of the airflow can flow out through the first wind outlet 19 between the first wind-guiding sheet 160 and the first fan 40, and a majority of the airflow flows out through the first wind outlet 164 and continues to flow towards the distal end of the first wind channel 16, thereby equalizing the wind outlet volume of the first wind channel 19 at the proximal end corresponding to the first wind channel 16, so that the wind volume at each position of the first wind outlet 19 is relatively uniform, and meanwhile, the arrangement of the first wind-guiding sheet 160 can also change the flowing direction of the airflow from the first wind outlet 19 between the first wind-guiding sheet 160 and the first fan 40, so that the airflow can be vertically blown upwards towards the face of the human body when flowing out from the part of the first wind outlet 19, rather than an inclined blow back neck. In the illustrated embodiment, the first end of the first air guiding plate 160 is integrally connected to the upper sidewall of the first casing 10, and the airflow of the first fan 40 can only continue to flow to the distal end of the first air duct 16 through the first air outlet portion 164. It should be understood that the first end of the first wind-guiding plate 160 may be spaced apart from the upper side wall of the first casing 10, so that a small portion of the airflow of the first fan 40 may flow out from the space between the first end of the first wind-guiding plate 160 and the upper side wall of the first casing 10 and continue to flow toward the distal end of the first wind channel 16.

In the illustrated embodiment, the second end of the second wind-guiding sheet 162 is integrally connected to the partition 34, and all the airflow flowing into between the first wind-guiding sheet 160 and the second wind-guiding sheet 162 through the first wind-outlet portion 164 flows obliquely upward under the action of the second wind-guiding sheet 162, wherein a part of the airflow passes through the second wind-guiding sheet 162 and continues to flow to the distal end of the first air duct 16, so that a part of the airflow can flow out through the first wind outlet 19 between the second wind-guiding sheet 162 and the first wind-guiding sheet 160, and the remaining part of the airflow flows out through the first wind outlet 19 between the second wind-guiding sheet 162 and the second casing 20, so as to equalize the wind outlet amount of the first wind outlet 19 at different positions corresponding to the first air duct 16, and at the same time, when the airflow flows out from the first wind outlet 19 between the first wind-guiding sheet 160 and the second wind-guiding sheet 162, the flow-out direction is substantially perpendicular to the extending direction of the first wind outlet 19, i.e. so that the wind is not blowing directly towards the back neck. It should be understood that the second end of the second air guiding plate 162 and the partition plate 34 may also be spaced apart, so that a small portion of the air flow can flow out from the space between the second end of the second air guiding plate 162 and the partition plate 34 and continue to flow toward the distal end of the first air duct 16.

Preferably, the first air duct 16 further includes a third air-guiding sheet 168 disposed between the first air-guiding sheet 160 and the second air-guiding sheet 162, and the length of the third air-guiding sheet 168 is much shorter than that of the second air-guiding sheet 162, so that the airflow can cross the third air-guiding sheet 168 and reach the second air-guiding sheet 162. One end of the third air guiding plate 168 is integrally connected to the partition plate 34, and the other end is away from the upper sidewall of the first casing 10. Preferably, an included angle between the third air guiding plate 168 and the partition plate 34 is greater than an included angle between the second air guiding plate 162 and the partition plate 34, that is, an upward inclination angle of the third air guiding plate 168 relative to the second air guiding plate 162 is larger, the airflow flowing out through the first air outlet portion 164 is firstly guided upward greatly under the action of the third air guiding plate 168, the airflow is diffused between the first air guiding plate 160 and the second air guiding plate 162 along with the flowing airflow, and then is guided upward again under the action of the second air guiding plate 162, so as to ensure that the air outlet volume at each position of the first air outlet 19 is uniform.
