Compared with the first wall portion 131 extending away from the second wall portion 132 in an inclined manner and the second wall portion 132 extending toward the first wall portion 131 in an inclined manner, the extending directions of the first wall portion 131 and the second wall portion 132 are consistent with the inclined direction of the wind guiding sheet 12, which is beneficial to synchronously adjusting the wind outlet angle and guiding the wind direction. If the first wall portion 131 extends obliquely away from the second wall portion 132, a projected area of the first wall portion 131 in the direction of the fan 5 is increased, that is, a blocking surface of the first wall portion 131 against wind is increased, and the blocking of the first wall portion 131 against wind is increased, which is not favorable for smooth air flow.
