[0002] At present, in conventional turbine fans, whether single-turbine or multi-turbine overlapping, the spiral direction of the turbine is arranged to rotate in the same direction relative to the air inlet, so that the wind-cutting surface of each blade extends outward from near the center of the turbine, resulting in a vacuum suction effect at the central air intake when the turbine is running.

[0003] In the prior art, a turbo blower is composed of a motor, a fan, a volute and a lower cavity. Therefore, when using the turbo blower, the fan and the volute are assembled, and then the lower cavity is placed at the bottom of the motor to support the position of the motor. At the same time, the motor delivery end is combined with the assembled fan, and then the motor is started, so that the turbo blower can be used. However, when the turbo blower is in use, since the turbo blower is controlled by a motor, the air volume of the turbo blower cannot be controlled, so that the turbo blower cannot control the air volume as needed.
