<p>A sleep fan (1) comprises a shell (10), the shell (10) having a base (11) and a pushing body (12) extending upwards from the base (11). The base (11) has a pair of side walls (13) that are separated by a certain distance, and one bottom surface (14) that can be placed on the ground. The sleep fan (1) further comprises a cross flow fan (20), placed between the pair of side walls (13) and having an axis (21), the axis (21) being basically parallel to the bottom surface (14) and the pair of side walls (13). The sleep fan (1) further comprises multiple air inlets (15), provided at positions, on the side walls (13), corresponding to the cross flow fan (20), and further comprises a motor (23), placed in the base and driving the cross flow fan (20), and an air guiding device (40), having a main body (41) slidably sleeved on the pushing body (12) and a header (42) having a certain angle with the main body (41). The air inlets of the sleep fan can be arranged on a side wall of any surface, the speed of an air flow flowing through the air inlets is reduced, and the noise and the energy consumption of the motor are reduced.</p> |
