Abstract:
Disclosed is a fan. The fan comprises: an air outlet frame which is provided with a first air outlet (b) provided in an extending direction of the air outlet frame, and a second air outlet (a) provided in a peripheral surface of the air outlet frame; and several flow deflectors (4) arranged in the air outlet frame and arranged between the first air outlet and the second air outlet, wherein the flow deflectors are driven by an external force to have a first state of sealing the first air outlet and guiding fluid to the second air outlet and a second state of opening the first air outlet. According to the fan, a first air outlet and a second air outlet are provided in an air outlet frame, and the opening/closing of the first air outlet is controlled by means of a flow deflector structure. When the first air outlet is opened, the fan generates air output at an angle in a direction of the first air outlet, and when the first air outlet is closed, airflow flows out of the second air outlet under the action of the flow deflectors; and the second air outlet is provided in a peripheral surface of the air outlet frame and can meet the requirement for air output in a circumferential 360-degree range of the fan, so that an air outlet angle is increased to meet the requirement of air blowing in different directions for a user.
