Hair dryer
The invention relates to an air blower which comprises a shell and a fan assembly, an air inlet and an air blowing opening are formed in the shell, and airflow flows in from the air inlet and flows out from the air blowing opening; the fan assembly at least comprises a first fan and a second fan; and in one working mode of the blower, the first fan and the second fan rotate in opposite directions. According to the air blower, the first fan and the second fan are at least arranged, on one hand, the flow speed of airflow is overlapped, and therefore the speed of the airflow flowing out of the air blowing opening is increased, and the requirement of a user for high air speed is met. And on the other hand, the rotation directions of the first fan and the second fan are opposite, so that the second fan can absorb the radial component force generated by the first fan on the airflow, the radial component force is changed into useful work on the second fan, and the airflow moves in the axial direction after passing through the second fan. In addition, the two fans enable the speed of airflow flowing out of the air blowing opening to be increased, and the requirement of a user for high air speed is met.
本申请涉及一种吹风机，包括壳体和风扇组件，其中，壳体形成进风口和吹风口，气流从进风口流入，并从吹风口流出；风扇组件至少包括第一风扇和第二风扇；在吹风机的一种工作模式下，第一风扇和第二风扇旋转方向相反。该吹风机通过至少设置第一风扇和第二风扇，一方面使得气流的流速进行叠加，从而使得气流从吹风口流出的速度得到提高，满足用户对高风速的需求。另一方面，第一风扇和第二风扇旋转方向相反，使得第二风扇可以吸收第一风扇对气流产生的径向分力，使径向分力变成对第二风扇的有用功，并且使得气流经过第二风扇后，实现沿轴向运动。此外，两个风扇使得气流从吹风口流出的速度得到提高，满足用户对高风速的需求。
